Hi all,
We've finished the PoC of isolation level 3 along with the new TFM HAL on the feature branch.
And now we are migrating the patches to master branch by cherry-picking, squashing and refining.
Here are the several topics ongoing parallel:
* Linker script changes for isolation L3<https://review.trustedfirmware.org/q/topic:%22linker_script_isolation%22+(s…>
* Isolation HAL API<https://review.trustedfirmware.org/q/topic:%22isolation_api_implementation%…>
* SPM log<https://review.trustedfirmware.org/q/topic:%22SPM_LOG%22+(status:open%20OR%…>
* SP log<https://review.trustedfirmware.org/q/topic:%22tfm_sp_log%22+(status:open%20…>
And the HAL API docs:
* Docs: Design of the TF-M isolation HAL<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/4829>
More patches will be coming soon, will keep you update-to-date.
Please help on reviews, thanks.
Best Regards,
Kevin

Subject: [TF-M] Feature branch 'feature-isolation-level3' is created for related patches merging
Hi,
A new branch created for two repos 'TF-M/tf-m-tests' and 'TF-M/trusted-firmware-m', this feature branch is for isolation related patches merging.
The POC patches would come in following days, first platform would be AN521. If you want to try this branch, please:
IMPORTANT:
Checkout 'feature-isoaltion-level3' branch for both 'TF-M/tf-m-tests' and 'TF-M/trusted-firmware-m'.

Hi,
Thank Tamas for the scenario, this is a good example.
There were some queries and initial investigations before, which shows that some users want to protect the implementation of their services, and check if there are mechanisms to help on that. I think isolation level 3 is applicable to this scenario.

Hi Andrej,
the following scenario comes to my mind:
* There is a product where secure services from different vendors are merged together and these are together make up the ARoT code.
* There is a vendor who has a novel algorithm what he wants to protect against reverse engineering.
* Image is delivered to the device in encrypted format. But on the device it is decrypted when moved to primary slot.
* This secure partition needs the L3 isolation to be hidden from the other secure services within ARoT code.

Hi Kevin,
Do you know any real (not academic) MCU application where L3 isolation is required?
People ask, but I have nothing to tell. Even for L2 is difficult to find something, for most of cases L1 is enough.

Hi Chris,
I've raised a ticket https://github.com/ARM-software/psa-arch-tests/issues/239 on PSA Arch test github repo. It will be fixed by PSA Arch test team later.
We will follow the fix status. Thanks again for reporting this issue.

Subject: Re: [TF-M] Another build issue
Hi Chris,
I agree with you. It looks like PSA arch test doesn't check the correct clone destination.
According to https://github.com/ARM-software/psa-arch-tests/blob/master/api-tests/CMakeL…, PSA arch test checks whether psa_qcbor exists.
However, the actual clone destination of psa_qcbor folder is under CMAKE_CURRENT_BINARY_DIR as https://github.com/ARM-software/psa-arch-tests/blob/master/api-tests/CMakeL… sets.
Therefore, I guess this issue will be triggered as long as CMake script execution is in the different directory as binary folder is.
I changed the destination to ${CMAKE_CURRENT_BINARY_DIR}/${PSA_TARGET_QCBOR} in check step and it looks like the issue is fixed.
IMOO, the quick workaround is to entirely remove the build directory.
I will discuss with Raef to determine a final solution.
Thanks a lot for reporting this issue!

Hi Anton
If it's not possible to avoid a file generation now, it's good to have pre-generated files for a most typical configuration (l2, IPC etc.).
As I mentioned before, ideally to use TFM as a real component/framework without generation of any source code.
BUT If you believe, this requirement breaks a TFM concept, just tell us.
Thanks,

Try to make TFM a component/framework, which is configurable by compile & run time parameters.

Subject: [TF-M] Generated files location
Hi,
Some source files in TF-M are templated and generated inside /<build_dir>/generated/ on the fly as a part of build process. This guaranty consistency between templates and generated but might make a trouble for IDE, where not all source files exist at the first run.
I see 2 options for solution:
1. Explicitly generate those files via cmake as a part of IDE project creation (1 time action)
2. Relay on CMSIS Pack for IDE, where generated files must be presents
Any alternative thoughts?

Looks like that test is indeed not supported on PSoC64. The error message threw me because it says what the valid values are for -DTARGET (which does include one containing "psoc64"), but it doesn't tell me what -DTAREGT was actually set to.

We definitely used to be able to at least build ConfigPsaApiTestIPC.cmake (and the level 2 version) for PSoC64 under the old build system. It looks like we've always done so with one of the other PSA test suites also selected, which doesn't seem to be an option with the new build system.
Is there an example TEST_PSA_API=IPC build for another platform I can look at?

Looking at docs/getting_started/tfm_build_instruction.rst, it mentions that TEST_PSA_API=IPC is a valid option ("Firmware Framework test suite"). When I try to configure for that build, though, I get an error:

Hi,
Some source files in TF-M are templated and generated inside /<build_dir>/generated/ on the fly as a part of build process. This guaranty consistency between templates and generated but might make a trouble for IDE, where not all source files exist at the first run.
I see 2 options for solution:
1. Explicitly generate those files via cmake as a part of IDE project creation (1 time action)
2. Relay on CMSIS Pack for IDE, where generated files must be presents
Any alternative thoughts?
Anton
Hi, yes apologies that seems to have been lost. I was doing my best to track changes in the original cmake but it seems this one got missed.
Can I ask - for the vendor triplet compilers (arm-etc-eabi-gcc), is it a compiler that the vendor is developing? In the new buildsystem, it might make sense to create a new compiler toolchain file that is almost identical to the GNU one, which would allow the two compilers to diverge slightly (in command-line options etc) if necessary.

It looks like the GNUARM_PREFIX changes got dropped as part of the new build system.
Can someone look at restoring those changes?

Tárgy: Re: [TF-M] Behavior difference in Crypto IPC vs Library modes
Hi Soby and Summer,
Thank you for pointing me to the complete chain of patches. I didn’t notice. With this, PSoC64 behaves quite well without any buffer changes. In fact, the results look better than previously published AN521 results – what are the latest AN521 results? It looks like 250 and 251 now passes but failed in previous AN521 results. Again, this is for PSoC64
As for Musca-B1, it looks like it is better (CC312 enabled). 241/242 is still failing and 250 is failing (passes for PSoC64). Disabling CC312 will result in 241/242 passing
Thank you,
Ray

Subject: RE: Behavior difference in Crypto IPC vs Library modes
Hi Raymond,
Some of the PSA Crypto tests require a larger buffer size and previously this was done within the build system. This size is required irrespective of IPC or Library mode. The new build system broke this buffer size configuration for API tests and the patch mentioned by Summer resolves that. Could you try with that and let us know ?
Regarding Musca-B1, we switched to using Cryptocell as default for that platform recently. There are some limitations for the CC-312 with respect to some crypto APIs and I suspect the failures are related to this. I will create a ticket to look further into this. Meanwhile could you try whether you have failures if you disable CC-312 for Musca-B1 :

Hi Raymond,
Do you cherry-pick all the series patches (topic:

) or just only pick the one Soby provided?
I testes on AN521, without all the series patches, 219, 241, 242, and 243 are failed. But when you cherry-pick all series patches, they can pass.
And I think patch https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/6251 already increase the size for CRYPTO_ENGINE_BUF_SIZE.
Thanks,

Subject: Re: [TF-M] Behavior difference in Crypto IPC vs Library modes
Hi Soby,
Thank you for that fix! It does indeed fix this particular issue when using IPC.
On another note, I’ve been running Musca-B1 and the results differ from what you sent out in the past for AN521. Specifically, Musca-B1 fails 219, 241, 242, and 243. Is this something you can have a look at on the Musca-B1 side?
With that said, I’ve been running on PSoC64 and I can reproduce the AN521 results. I needed the patch you provided below but I was still running into memory issues and I had to bump the following (both of them).
#define TFM_CRYPTO_IOVEC_BUFFER_SIZE (8120)
#define TFM_CRYPTO_ENGINE_BUF_SIZE (0x5040) /* >8KB for EC signing in attest */
If I do not bump these, I would see 239 to 244 fail. Might you have any comments on the larger size requirements for these? Possibly when running in IPC mode?
Thank you,

Subject: RE: Behavior difference in Crypto IPC vs Library modes
Hi Raymond,
After further analysis, it seems to me that having separate checks for Library mode and IPC mode is the easiest way to go. The current design was done in such a way that both Library and IPC mode can reuse the same crypto service API involving IOVECs. Any change to how the API is invoked from the tfm_crypto_call_sfn() will have ramifications for Library mode.
I have done a patch with different checks for IPC and Library mode here: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/6432 . The patch relaxes the checks for IPC mode to allow empty buffers and hardens the checks for Library mode. Hopefully this should resolve the issue.

Hi Raymond,
As you pointed out, the difference in this case basically boils down to how the 2 models handles empty buffers. In the library mode, the empty buffers are passed down to the target API whereas the IPC mode optimizes the empty buffer from the IOVEC by reducing the buffer length. This results in different error codes in the 2 modes.
The sanity check of IOVEC in incoming sizes is needed and I less inclined to remove it or enhance it. The error code certainly seems to be one way to resolve this problem. The other option is to make the IPC mode IOVEC less aggressive in optimizing away zero buffers from IOVEC (Need more investigation) thus attaining parity with library mode.

Hi all,
I’m seeking some assistance in determining the correct fix for a difference in behavior between IPC and Library modes that cause the Crypto PSA Arch Tests to fail when using IPC. Specifically, I’ve been testing on a PSoC64 for IPC mode and Musca-B1 for Library mode. The problem I am encountering is related to this check in crypto (e.g. crypto_aead.c in secure_fw/partitions/crypto).
if ( !((in_len == 2) || (in_len == 3)) || (out_len > 1)) {
return PSA_ERROR_CONNECTION_REFUSED;
}
This is true for direct function call since in_len and out_len are sizes of in_vec[] and out_vec[]. However, in library mode, in_len and out_len is not based on the size of in_vec[] and out_vec[] but based on the contents. Specifically, out_len is determined via the following in tfm_crypto_call_sfn().
/* Check the number of out_vec filled */
while ((out_len > 0) && (msg->out_size[out_len - 1] == 0)) {
out_len--;
}
>From the above, if out_size (which is passed in by the user) is 0, the resultant out_len will be 0. The out_len is passed into the crypto function and PSA_ERROR_CONNECTION_REFUSED is returned due to the check above. PSA, on the other hand, expects PSA_ERROR_NOT_SUPPORTED to be returned. Btw, in_len suffers from the same issue.
I’m not sure if the check above is valid for IPC mode. I’ve removed the check temporarily to avoid the problem. However, if the check still makes sense, possibly it should return PSA_ERROR_NOT_SUPPORTED instead of PSA_ERROR_CONNECTION_REFUSED.
Thank you. I look forward to comments.

Ah okay. This is the behavior we saw with the other VS generators, and why we added the check to make sure "Unix Makefiles" or "Ninja" was used. Because it sets the C compiler to MSVC, it won't correctly compile TFM (which currently only supports ARMClang, GCC, and IAR). While there are other symptoms, such as the issues with python etc, this is the main one.
I'd advise to just use -G"Unix Makefiles" (or ninja)

/* Check the number of out_vec filled */
while ((out_len > 0) && (msg->out_size[out_len - 1] == 0)) {
out_len--;
}
>From the above, if out_size (which is passed in by the user) is 0, the resultant out_len will be 0. The out_len is passed into the crypto function and PSA_ERROR_CONNECTION_REFUSED is returned due to the check above. PSA, on the other hand, expects PSA_ERROR_NOT_SUPPORTED to be returned. Btw, in_len suffers from the same issue.
I'm not sure if the check above is valid for IPC mode. I've removed the check temporarily to avoid the problem. However, if the check still makes sense, possibly it should return PSA_ERROR_NOT_SUPPORTED instead of PSA_ERROR_CONNECTION_REFUSED.
Thank you. I look forward to comments.

Hi, Raef,
I can get past the CMSIS issue by dup'ing the GNU links. It now fails for lack of the correct Python.
Using the -G option, CMakeCache.txt lists all the pythons in my system and the build completes:
$ grep python cmake_build/CMakeCache.txt
PYTHON_EXECUTABLE:FILEPATH=C:/Python/Python27/python.exe
FIND_PACKAGE_MESSAGE_DETAILS_Python3:INTERNAL=[C:/Users/cXXXXX/AppData/Local/Programs/Python/Python38-32/python.exe][cfound components: Interpreter ][v3.8.5()]
_Python3_EXECUTABLE:INTERNAL=C:/Users/cXXXXX/AppData/Local/Programs/Python/Python38-32/python.exe
Without the -G option, the compiler is MSVC, and the cache has no entry for python at all.

Hi, Raef,
The combination that worked was the most-recent commit and gnu tools (-G option). Using VS it fails at lib/ext/CMSIS_5/CMakeLists.txt:25 for lack of CMSIS RTX static libraries.
...this command worked....

Thanks. I'm interested if you've managed to build TFM using the visual studio generator? That check was actually added because we had a problem with at least one of the visual studio generators (VS10) setting the C compiler to `MSVC`. If you've managed to get it to build with VS16, then we can look in to adding that as a known good generator.

Hi,
I'm interested in the changes that you made to the validity checks, would you mind sending a patch / outlining what you had to change. The windows generator checks are still not working exactly as they should and I'd like to know what your experience was.
For the build failure, I believe this might be related to an issue with the windows PSA file generation. We've got a patch in review for this at https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/6386, can you test and see if that fixes the problem.

Hi,
While digging the clean issue brought up by Soby, I started wondering if external dependency handling would be better in a slightly different way. There is a lot of hack in the build system around including the psa-arch test project, mostly to work around cmake limitations on namespaces and symbol separation. A stronger barrier could eliminate the mess. In TS we use the following pattern (let's call it "Internal Project"):
* External dependencies are fetched with fetch_content()
* Right after the fetch, execute_process() is called to start the build of the component. So external component builds configuration time.
* The project get's installed into a directory and the main project is using the installed content, possibly through find_package().
* Benefits:
* This gives a stronger separation, elimination any name clash between the main project and the external dependency. Also global settings cannot collide like when a dependency sets CMAKE_BUILD_TYPE.
* Faster main project build times, as external projects are only built once.
* Makes it more "natural" to use an externally built binary for an external component. This might be handy from QA perspective if binary releases are going to happen. (If ever of course.)
* Strong separation could allow using different version of the same tools for components. (i.e. main project is built with GCC, component with IAR.)
* Drawbacks:
* It is harder to develop the external component together with tf-m s tracking changes is more difficult. Might be a problem if debugging tf-m vs external component interaction. This should be rare and might be an acceptable issue.
* It is unnatural to run builds configuration time in cmake world.
* Configuration phase will take longer.
* Since the build happens right where the external component is added (point A), cmake execution flow might need to be different to ensure all information needed to configure the external component is present at point A.
* Since external component is built by a separated cmake run, tool detection happens separate. This means the same tools will be searched for multiple times. Initial cache files can be a workaround.
This is very similar to how external projects work in cmake, but makes better integration possible. The main project can use information from the dependency as it's source and output files become available configuration time. In turn external project changes are harder to track.

Hi,
I tried to dig deeper into this, but the cmake command used by Soby fails for me.
"
[ 33%] Performing patch step for 'psa_arch_tests-populate'
error: patch failed: api-tests/platform/targets/tgt_dev_apis_tfm_an521/nspe/pal_driver_intf.c:128
...
"
It would be nice to understand why cmake fails to clean properly, but well, I cannot deep-dive due to the above. What I wanted to check is if https://cmake.org/cmake/help/v3.15/prop_tgt/ADDITIONAL_CLEAN_FILES.html could be used to get "make clean" remove the psa-arch test binary directory. But:
* I am not sure which build directory is used. I have the feeling we use ${CMAKE_CURRENT_BINARY_DIR}/psa_api_tests and not psa_arch_tests_BINARY_DIR, which would be build\lib\ext\psa_arch_tests-build. Strange.
* ADDITIONAL_CLEAN_FILES was introduced in cmake v3.15 and if my memories are correct tf-m allows an older version if not using IAR.
Soby: can you please test if ADDITIONAL_CLEAN_FILES works? This solution would give a more streamlined.

Thanks Karl, Gyorgy for your inputs.
I agree with the principle that `BUILD` shall be only folder the cmake modifies. The trouble is, after a `make clean`, there are still artefacts from the previous configuration which affects the new build and gives the wrong output. Hence the suggestion to introduce a `cleanall` custom target which endeavours to clean the all the remnant config information from previous build and leave auto cloned dependant repositories untouched (or maybe print some status info).
Does that sound like a good plan then ?

Subject: Re: [TF-M] New TF-M Build doesn't track config changes
Hi,
I think the build directory is owned by cmake and the same rules shall apply to all files there. Also the only directory cmake does modify without the users consent shall be the build directory. As long as cmake is owning the external dependencies it is the responsibility of the build system to keep the dependencies in a healthy state and to ensure the correct version is built. To do this safely the "clean" operation, which is used to get out of a "non-operational" state, shall fix the dependencies too.
So the correct operation (in my opinion) is to make the dependency download work in the following way:
* If the dependency is already present at the target location, cmake shall use it as is. Possibly some status information should be printed (i.e. version number, if the git working copy is dirty etc...)
* If not cmake shall do the fetch.
This way if the user specify an external location (one not in the build directory), cmake will "export" the dependency when the first fetch is done, and do no modifications after. This gives us a well-defined act of handing over the responsibility of keeping the dependency clean.
As far as I can see (was not digging into the details) this more or less matches how the current implementation works, and what is missing is more details in the documentation.

I met the same problem before, and I think your suggestions are helpful. There might be more check needed if the 'make clean' does not delete the auto cloned repos. Because the dependencies may update by a new TFM commit.
The new build system supports to specify the patch of each dependency, which can avoid clone automatically to the build folder each time. Hope it can mitigate the inconvenient scenario.

Subject: [TF-M] New TF-M Build doesn't track config changes
Hi,
With the new build system, TF-M downloads all dependant repositories to the BUILD folder as part of CMAKE configuration. CMake does provide `make clean` target to clean the build and rebuild but this doesn't track any config changes between the builds. Previously, the CMake workflow was to delete all contents in the BUILD folder before re-configuring for a new build but now this means the developer has to re-download all the dependant git repositories before the project can be build again. This can be a slow and cumbersome process for developers. Deleting the CMakecache.txt doesn't seem to solve the problem either.
The most obvious solution is to move the cloned repositories outside the BUILD/ folder , so we can follow the previous workflow of deleting the BUILD folder before re-build. The sample test sequence to reproduce the problem is given below:
/* Build secure regressions test suite */
$ make clean; cmake .. -DTFM_PLATFORM=mps2/an521 -DCMAKE_TOOLCHAIN_FILE=../toolchain_GNUARM.cmake -DTEST_S=ON -DCMAKE_BUILD_TYPE=Debug; make install
/* reconfigure and build PSA Crypto API test suite */
$ make clean; cmake .. -DTFM_PLATFORM=mps2/an521 -DCMAKE_TOOLCHAIN_FILE=../toolchain_GNUARM.cmake -DCMAKE_BUILD_TYPE=Debug -DTEST_PSA_API=CRYPTO; make install
Built binary is still for regression test suite.
There are multiple suggestions to solve the problem, One is to move the clone repositories outside the BUILD/ folder, or introduce a build target like `make cleanall` which does the equivalent of rm -rf !(lib) within the BUILD folder (i.e the build target will remove all folders except the lib folder which has the cloned repositories). Please let us know of your suggestions on this.
Best Regards
Soby Mathew

This can be a slow and cumbersome process for developers. Deleting the CMakecache.txt doesn't seem to solve the problem either.
The most obvious solution is to move the cloned repositories outside the BUILD/ folder , so we can follow the previous workflow of deleting the BUILD folder before re-build. The sample test sequence to reproduce the problem is given below:
/* Build secure regressions test suite */
$ make clean; cmake .. -DTFM_PLATFORM=mps2/an521 -DCMAKE_TOOLCHAIN_FILE=../toolchain_GNUARM.cmake -DTEST_S=ON -DCMAKE_BUILD_TYPE=Debug; make install
/* reconfigure and build PSA Crypto API test suite */
$ make clean; cmake .. -DTFM_PLATFORM=mps2/an521 -DCMAKE_TOOLCHAIN_FILE=../toolchain_GNUARM.cmake -DCMAKE_BUILD_TYPE=Debug -DTEST_PSA_API=CRYPTO; make install
Built binary is still for regression test suite.
There are multiple suggestions to solve the problem, One is to move the clone repositories outside the BUILD/ folder, or introduce a build target like `make cleanall` which does the equivalent of rm -rf !(lib) within the BUILD folder (i.e the build target will remove all folders except the lib folder which has the cloned repositories). Please let us know of your suggestions on this.

Thanks Karl, Gyorgy for your inputs.
I agree with the principle that `BUILD` shall be only folder the cmake modifies. The trouble is, after a `make clean`, there are still artefacts from the previous configuration which affects the new build and gives the wrong output. Hence the suggestion to introduce a `cleanall` custom target which endeavours to clean the all the remnant config information from previous build and leave auto cloned dependant repositories untouched (or maybe print some status info).
Does that sound like a good plan then ?

Hi,
I think the build directory is owned by cmake and the same rules shall apply to all files there. Also the only directory cmake does modify without the users consent shall be the build directory. As long as cmake is owning the external dependencies it is the responsibility of the build system to keep the dependencies in a healthy state and to ensure the correct version is built. To do this safely the "clean" operation, which is used to get out of a "non-operational" state, shall fix the dependencies too.
So the correct operation (in my opinion) is to make the dependency download work in the following way:
* If the dependency is already present at the target location, cmake shall use it as is. Possibly some status information should be printed (i.e. version number, if the git working copy is dirty etc...)
* If not cmake shall do the fetch.
This way if the user specify an external location (one not in the build directory), cmake will "export" the dependency when the first fetch is done, and do no modifications after. This gives us a well-defined act of handing over the responsibility of keeping the dependency clean.
As far as I can see (was not digging into the details) this more or less matches how the current implementation works, and what is missing is more details in the documentation.

Hi Soby,
I met the same problem before, and I think your suggestions are helpful. There might be more check needed if the 'make clean' does not delete the auto cloned repos. Because the dependencies may update by a new TFM commit.
The new build system supports to specify the patch of each dependency, which can avoid clone automatically to the build folder each time. Hope it can mitigate the inconvenient scenario.

Subject: [TF-M] Behavior difference in Crypto IPC vs Library modes
Hi all,
I'm seeking some assistance in determining the correct fix for a difference in behavior between IPC and Library modes that cause the Crypto PSA Arch Tests to fail when using IPC. Specifically, I've been testing on a PSoC64 for IPC mode and Musca-B1 for Library mode. The problem I am encountering is related to this check in crypto (e.g. crypto_aead.c in secure_fw/partitions/crypto).
if ( !((in_len == 2) || (in_len == 3)) || (out_len > 1)) {
return PSA_ERROR_CONNECTION_REFUSED;
}
This is true for direct function call since in_len and out_len are sizes of in_vec[] and out_vec[]. However, in library mode, in_len and out_len is not based on the size of in_vec[] and out_vec[] but based on the contents. Specifically, out_len is determined via the following in tfm_crypto_call_sfn().
/* Check the number of out_vec filled */
while ((out_len > 0) && (msg->out_size[out_len - 1] == 0)) {
out_len--;
}
>From the above, if out_size (which is passed in by the user) is 0, the resultant out_len will be 0. The out_len is passed into the crypto function and PSA_ERROR_CONNECTION_REFUSED is returned due to the check above. PSA, on the other hand, expects PSA_ERROR_NOT_SUPPORTED to be returned. Btw, in_len suffers from the same issue.
I'm not sure if the check above is valid for IPC mode. I've removed the check temporarily to avoid the problem. However, if the check still makes sense, possibly it should return PSA_ERROR_NOT_SUPPORTED instead of PSA_ERROR_CONNECTION_REFUSED.
Thank you. I look forward to comments.

Subject: Re: [TF-M] Disabling IRQ test with new build system
Hi Chris,
Thanks a lot for reporting this.
It looks like the IRQ test case is enabled on NS side as long as the Platform service is enabled. The IRQ test service in SPE is controlled by `TFM_ENABLE_IRQ_TEST`, which, however, is neither explicitly configured in CMake nor exported for manual configuration. Therefore IRQ test service is not enabled by default.
Thus the IRQ test case will hang the execution and configuration of IRQ test in command line won’t take effect.
I’ve been looking for the solution. Just need some time to sort out the dependencies of those test control flags in the new build system. 😊
Sorry for any inconvenience.

Hi,
The IRQ test part of the CORE_TEST is all conditioned on TFM_ENABLE_IRQ_TEST, and docs/reference/services/core_test_services_integration_guide.rst states that “A platform can skip IRQ handling test by setting ``TFM_ENABLE_IRQ_TEST`` to ``OFF`` in its cmake configuration file.”, but doing so doesn’t seem to actually work. I tried a number of options to the cmake command (including -DTFM_ENABLE_IRQ_TES=OFF, -U TFM_ENABLE_IRQ_TEST), too, but I can’t figure out how to avoid that test.

Hi Tamas,
It didn't make a difference. I have an old muscb1 image around and that continues to work fine but the new images do not work.
I wrote 2MB of 0xFF btw.

Hi Raymond,
The build command and the hex creation are correct.
Could you try to erase the entire eFlash before programming it?
It can be done with Keil MDK, or you can create a hex file with srec_cat which only contains 0xFF bytes and program that one to the board.
Let me know whether does it solved the issue.

The observed behaviour has two reason:
- In the new build system the default CMAKE_BUILD_TYPE=Release. In this case the logging is disabled in MCUboot to get smaller binary. You can set manualy to Debug in the command line to enable logging from bootloader
* This commit 7d591a684b4abb0f61fbba8668dd6ea7b4b68698 introduced a crash in Musca S1/B1. Fix is ongoing.

Hi,
FIY this variable in the Linux world used to be called "CROSS_COMPILE" and both TF-A and OP-TEE is using the same convention. Would it be possible to align with this and rename the variable? For backwards compatibility it could be possible to use both for a while, and issue a warning when the with a deprecation message when the old one is sued.

Hi, yes apologies that seems to have been lost. I was doing my best to track changes in the original cmake but it seems this one got missed.
Can I ask - for the vendor triplet compilers (arm-etc-eabi-gcc), is it a compiler that the vendor is developing? In the new buildsystem, it might make sense to create a new compiler toolchain file that is almost identical to the GNU one, which would allow the two compilers to diverge slightly (in command-line options etc) if necessary.

Hi Øyvind
Yes, you are right, we don't use wchar_t within TF-M and it does seem a trivial optimization without much benefit for TF-M other than introducing incompatibilities. Could you submit a patch to remove the same from GCC and ARMCLANG ?

Could you try to do a debug build? By default the build type is release and in this case the MCUboot does not log anything.
Set '-DCMAKE_BUILD_TYPE=Debug' in the command line when invoking the CMake generation phase.

Dear all,
I’m a researcher exploring TF-M.
I have a Musca-A board, and I was able to build it with tests.
Now, it seems that the examples running the tests [1] are outdated: I simply do not have the same files.
My understanding is that I should merge two files (secure and non-secure) but it is not clear which ones and how the offset are computed.
Can somebody help me on this?
The output files in the /bin folder are: bl2, tfm_ns, and tfm_s in .axf, .bin, .elf, .hex, .map; tfm_s_ns.bin; and tfm_s_ns_signed.bin.

Hi Antonio,
And welcome to the TF-M community. To get a better understanding of your issue it I would like to ask from some further details, such as the HEAD of the TF-M which you are trying to build, as well as the HEAD of the test branche.
There has been a large overhaul of several components on the TF-M project, including the build system, so it would be good to have a common point of reference /
By examples, do you refer to the official user guide?
https://ci.trustedfirmware.org/view/TF-M/job/tf-m-build-docs-nightly/lastSt…
For Musca_A you only need the hex file to flash it, which is generated using the srec_cat command mentioned above which utilises the platform specific offsets and merges the signed secure and non-secure binaries with the bootloader.
If you are facing any issues flashing the HEX file, make sure that you have an up-to date daplink firmware.
https://community.arm.com/developer/tools-software/oss-platforms/w/docs/554…
If your output folder contains the HEX file, you can try flashing it by dragging and dropping, and see if it runs the regression tests.
Regards,
Minos Galanakis

Hi,
With the new build system, TF-M downloads all dependant repositories to the BUILD folder as part of CMAKE configuration. CMake does provide `make clean` target to clean the build and rebuild but this doesn't track any config changes between the builds. Previously, the CMake workflow was to delete all contents in the BUILD folder before re-configuring for a new build but now this means the developer has to re-download all the dependant git repositories before the project can be build again. This can be a slow and cumbersome process for developers. Deleting the CMakecache.txt doesn't seem to solve the problem either.
The most obvious solution is to move the cloned repositories outside the BUILD/ folder , so we can follow the previous workflow of deleting the BUILD folder before re-build. The sample test sequence to reproduce the problem is given below:
/* Build secure regressions test suite */
$ make clean; cmake .. -DTFM_PLATFORM=mps2/an521 -DCMAKE_TOOLCHAIN_FILE=../toolchain_GNUARM.cmake -DTEST_S=ON -DCMAKE_BUILD_TYPE=Debug; make install
/* reconfigure and build PSA Crypto API test suite */
$ make clean; cmake .. -DTFM_PLATFORM=mps2/an521 -DCMAKE_TOOLCHAIN_FILE=../toolchain_GNUARM.cmake -DCMAKE_BUILD_TYPE=Debug -DTEST_PSA_API=CRYPTO; make install
Built binary is still for regression test suite.
There are multiple suggestions to solve the problem, One is to move the clone repositories outside the BUILD/ folder, or introduce a build target like `make cleanall` which does the equivalent of rm -rf !(lib) within the BUILD folder (i.e the build target will remove all folders except the lib folder which has the cloned repositories). Please let us know of your suggestions on this.

Yes, it seems like the core tests slipped through conversion. I've already had a report of this and got a patch together but it needs some thorough testing since it affects the linking order.
I'll notify here once the patch is submitted for review. Should be this morning.

Subject: [TF-M] CORE_TEST and the new build system
It seems that docs/reference/services/core_test_services_integration_guide.rst hasn’t been updated to reflect the new build system (it says to build using ConfigCoreTest.cmake). That config isn’t mentioned in docs/getting_started/tfm_build_instruction.rst.
So how do I build the CORE_TEST stuff with the new build system (I’m particularly interested in the IRQ test).
Thanks,

Hi Raymond,
Thanks for reporting the issue!
The observed behaviour has two reason:
- In the new build system the default CMAKE_BUILD_TYPE=Release. In this case the logging is disabled in MCUboot to get smaller binary. You can set manualy to Debug in the command line to enable logging from bootloader
* This commit 7d591a684b4abb0f61fbba8668dd6ea7b4b68698 introduced a crash in Musca S1/B1. Fix is ongoing.

Subject: [TF-M] Musca-B1 and new build system
Hi all,
I am attempting to build Musca-B1 with the latest in master but I'm not able to get it to run (nothing shows on the UART). At a minimum, the User Guide is out of date in terms of how the final hex is created. So, I have a couple questions.
1. Is the latest tested with Musca-B1?
2. Can I obtain some updated information on how to build and create an image for Musca-B1?
Thank you,
Ray

Subject: [TF-M] Removal of MCUboot fork from TF-M
Hi,
In the last few quarter TF-M team have worked on actively to upstream the TF-M related features from the forked MCUboot repo to the original repository.
This activity has been finished recently and as a result the MCUboot fork has been removed from TF-M repo.
Currently TF-M exclusively relies on MCUboot project as a secure bootloader. From now on all new development will be directly contributed to the upstream repo.
List of feature which were upstreamed:
* HW rollback protection
* HW key integration
* Data exchange between MCUboot and runtime firmware
* RAM_LOAD boot mode
* DIRECT_XIP boot mode

Hello Jaouen,
I have a development issue when running TFM download process on the STM32L562.Print a error log"[ERR] Image in the secondary slot is not valid!" when download tfm_s_enc_sign.bin.ALL other 3 bin(tfm_s_sign.bin,tfm_ns_sign.bin,tfm_ns_enc_sign.bin) download success.
I follow the document UM2671 chapter 11.4 Download a new firmware image.
The project is en.stm32cubel5_v1-3-0.zip,file:Projects\STM32L562E-DK\Applications\TFM
Steps to reproduce:
1.run Projects\STM32L562E-DK\Applications\TFM\TFM_SBSFU_Boot\MDK-ARM\regression.bat to init device
2.build TFM_SBSFU_Boot application,TFM_Appli secure application,TFM_Appli non-secure application,Build TFM_Loader application

Hi,
I would merge this one as it has been put there review for a while, thanks all the reviewers.
This would provide a basic shape while we are creating new features, also could be viewed better after rendered.
There would be many points can be updated later, let’s try to use it and see how it works – Create issues at https://developer.trustedfirmware.org/ and assign to me if there are, reply here is also workable.

Subject: [TF-M] [RFC] The code review guideline
Hi,
We are creating one document to describe the code review guidelines:
https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5372
The goal of this document is to introduce the source management level concepts to be followed while reviewing a code – which try to simplify the contribution (but burdens the reviewers? 😉).
Difference to the `coding style`:
* It focuses more on the source placement, interface definition and including, etc.
As this document is keeping evolving in a period, the plan is we merge a simple version as start and adding more contents by new patches, so please give enough comments if you have, and don’t forget the concept: we want to make things rational and simple.
Thanks.

Thanks for the clarification. This would mean that given the current PSA Crypto design, the only way to achieve this would be to implement a custom RoT service in SPE. Hence the NSPE cannot make use of the key for arbitrary signing operation.

Yes, that does seem like a good candidate. From my reading, several aspects of provisioning seem to be outside TF-M realm.

I see, thanks. We use certificate chains when firmware images need from different vendors need to be deployed in different privilege levels or multiple boot stages are present in A-profile. The Platform boot guide document https://developer.arm.com/documentation/den0072/0101/ mentions this as well. Possibly this is an enhancement to MCUBoot (Boot loader for TF-M).
After talking with Adrian, I think there is consensus that certificate chain is a useful feature to have. So from my point of view, if there is some collaborative effort to develop such a service as TF-M specific extension, I think it would be very useful to the community.

Soby Mathew

Thanks for the clarification. This would mean that given the current PSA Crypto design, the only way to achieve this would be to implement a custom RoT service in SPE. Hence the NSPE cannot make use of the key for arbitrary signing operation.

Yes, that does seem like a good candidate. From my reading, several aspects of provisioning seem to be outside TF-M realm.

I see, thanks. We use certificate chains when firmware images need from different vendors need to be deployed in different privilege levels or multiple boot stages are present in A-profile. The Platform boot guide document https://developer.arm.com/documentation/den0072/0101/ mentions this as well. Possibly this is an enhancement to MCUBoot (Boot loader for TF-M).
After talking with Adrian, I think there is consensus that certificate chain is a useful feature to have. So from my point of view, if there is some collaborative effort to develop such a service as TF-M specific extension, I think it would be very useful to the community.

Hi all,
Just to let you know, some time ago Cypress has officially released the PSoC64 platform. With this, we are planning to stop supporting old PSoC64 development kits and move our focus on the new release boards.
This is mainly because the old boards were programmed with an old firmware which is not compatible with the changes we do to the TFM code and it would be an unnecessary overhead to support both versions.
Please let us know if it causes any issues.
The new PSoC64 kit:

Hi all
The new buildsystem has now been merged to both the trusted-firmware-m and
tf-m-tests repositories.
There are a few known issues:
* STM platforms run into issues with flash space when building under debug
configuration.
* nxp/lpcxpresso66s69 fails regression tests - this is being looked into as a
priority.
For building with the new buildsystem, there have been some changes to the
command-line. An example invocation is shown below.
```
cd <TFM root dir>
mkdir build && cd build
cmake .. -DTFM_PLATFORM=mps2/an521 -DCMAKE_TOOLCHAIN_FILE=../toolchain_GNUARM.cmake
make
```
CMAKE_TOOLCHAIN_FILE and TFM_PLATFORM are the only required arguments.
CMAKE_TOOLCHAIN_FILE is conceptually a replacement for COMPILER. It is a path to
one of the three toolchain files in the TFM root dir.
* <TFM root dir>/toolchain_GNUARM.cmake
* <TFM root dir>/toolchain_ARMCLANG.cmake
* <TFM root dir>/toolchain_IARARM.cmake
TFM_PLATFORM is conceptually a replacement for TARGET_PLATFORM. Unlike
TARGET_PLATFORM it takes as an argument the path between `platform/ext/target`
and the target dir. For example:
* -DTFM_PLATFORM=musca_s1
* -DTFM_PLATFORM=cypress/psoc64
* -DTFM_PLATFORM=nxp/lpcxpresso55s69
PROJ_CONFIG has now been removed. Instead configuration has been simplified
using composable variables.
Enable regression tests: -DTEST_NS=ON -DTEST_S=ON
Enable IPC mode: -DTFM_PSA_API=ON
Set isolation level: -DTFM_ISOLATION_LEVEL=2
So instead of ConfigRegressionIPC:
-DTEST_NS=ON -DTEST_S=ON -DTFM_PSA_API=ON
For integration with other projects, there is a new option:
-DNS=[ON/OFF]
If NS is set to OFF, TFM will build only the secure image (as bin tfm_s.axf) and
the PSA api as a static library. This should make integration with other
projects much simpler.
Other miscellaneous improvements:
* Full ninja support
* Automatic dependency management
* generation of axf, elf, hex and bin files for all outputs
* Full support for partial rebuilding and parallel building
* Modular support for crypto accelerators
* better integration of multi-core support
For full details of buildsystem variable changes, refer to
`docs/getting_started/tfm_build_instructions.rst` and
`config/config_default.cmake`
Raef
Thanks all for the inputs.
May I collect answers for these questions:
* Does the build system/IDE support sub-project for components and finally assemble them into one final image? The intention is to check the possibility to integrate TFM with sub-projects instead of a whole item.
* Is there scenarios that dynamic sections being added into sct/ld, how do you deal with this? A reference link is also helpful.
The intention:
TF-M is actually a set of components, and the secure firmware part (secure boot is another image binary so not listed here) contains:
1. Libraries.
2. Partitions.
3. SPM.
4. Image assembling with all above components.
The straight way is to generate ABC as *.a and assemble them together into a final image.
Then go through each component, A and C can be configured in C domain, as what they needs maybe just some feature flags. B is a bit special but we still could provide specification defined .json and its compatible .yaml manifest and pre-generated C-based manifest with preprocessors.
D is the hard part, as it needs special arrangement inside ld/sct, which make this discussion happen. Even the ‘include’ and ‘preprocessor’ are supported inside sct/ld, we still can not avoid the partitions including part, we can not do a foreach on the partition list which involve the preprocessor complexity into sct/ld. Looks like the templating can’t be avoided here. For platform specific requirements like:
* Some platform won’t separate RODATA and CODE;
* Some platform got non-continuous memory regions for special data;
Put a platform dedicated sct/ld into the platform folder would help; but to mitigate the effort of platform, a common sct/ld needs to be abstracted.
Thanks again for your great feedback.

Hello Gyrogy:
Your comment raises the question. Why is TF-M so complex and does it need to be the only answer? Either it needs to be simplified or respect must be paid to support in commercial tools as a first class citizen. Commercial tools are the path for large scale product developers. If they can’t engage TF-M with commercial tools or SiP tools then developers will face challenges to develop with it. It there are challenges they may even avoid using it in favor of simplified solutions much as they do today.
Multiple target use cases will be using various components of TF-M (MbedTLS with and without hardware interfaces, Attestation, Audit Logs, etc.):
1. Arm v8M – Cortex-M33, M35, M55
2. Dual Core Systems – Multiple possible configs
3. Cortex v6M of v7M – M0, M0+, M3 & M4
4. TF-A
5. Other Cortex-R & Cortex-A implementations
This reality argues for a more modular build packaging system that allows for it.
All the best!

Subject: Re: [TF-M] Proposal to separate SCT/LD into each platform folder
Hi Andrej,
TF-M relies heavily on compile time configuration, and C is quiet limited on that. This means we cannot rely on the only standardized part of the “ecosystem” solely, and we have to use non-standard tools. I would love to have a portable automation solution supported by most IDEs.
Yes, a lot of projects can go well with a single configuration header but unfortunately TF-M is more complex than that:
* How could we get information from manifest files to the build?
* How could we generate signed binary packages for the boot-loader?
* How could we control memory map in sync with the hw configuration in source files? (The current pre-processing linker files approach is already non-standard.)
None of these can be solved with IDEs in a portable way. I understand that adding IDE support for TF-M is challenging but the root cause is not how we implemented the build system, but how IDEs can handle the complexity needed by TF-M.

Hi Ken,
So we are using one default/typical configuration. If any change in it, a user have to do changes manually which are not clear without deeper knowledge of the TFM project.
But this is the issue of the TF-M chosen approach - fully rely on cmake preprocessing.
The proposal is to use approach which is good for all worlds (cmake and IDEs) and which is used by all embedded MCU open-source projects like MbedTLS, FreeRTOS, lwIP, FNET and etc.
Which is to have only one set of platform-independent files and the framework configuration from a user/project configuration file.
It will work for both worlds, will solve all configuration issues we have, and will make TF-M easy to use and more popular.
I am talking about this from very beginning. As no steps in right direction, we have a forked TF-M for our SDK.
Thanks George for support ;)

Hi Andrej,
Sounds like your IDE is using the default .sct/.ld file, may I ask some a question that:
* Is there a scenario that someone wants to add more partitions other than the default ones into your system, and how could they do that? I believe the existing .sct/.ld do not support extra partitions out of the default ones unless some manually modification is done.
We need to support more components (partition is the direct example), so in this case, the sct/ld can’t be avoided to be modified.
Or do you think if we put a specific .sct/.ld under nxp folder would work if there is no other partitions are needed?
Thanks.

Hi,
Good point, this is an important factor. I think templating can be IDE compliant as long as the IDE does support pre-build step(s). The current build flow already contains steps requiring this and thus I don’t think situation would be much worse with any mentioned solution than it is today.

Subject: Re: [TF-M] Proposal to separate SCT/LD into each platform folder
Hi Ken,
I think templating is a good approach here, the current C preprocessor based solution is a very limited implementation of this.
I see two main contenders for templating:
1. cmake has built in support for templating with the configure_file() [1] command. This would move ownership of this information info the build scripts, which are the focus point for such info already. A cmake based solution would feel more native to the existing system. On the other hand other solutions might have more features, which could lead to easier to read template files. Also cmake as a template engine is not that widely adopted.
2. jinja2 [2]. A widely adopted and more feature rich templating engine. TF-M already uses it for manifest file handling. I suggest using yahsa [3] instead of a custom pyhton script as the cli frontend though. This could speed up development as long as no complex processing is needed and the templates can be filled based on “simple” values.
Which of the above is the best for the task depends on template file readability and on complexity of the task. It could be nice if a clean split could be made, and we could stop using the C preprocessor based processing completely.
“Not sure if all these format support #include”
The build system works around that by implementing a compiler specific cmake function to add the pre-processing step for compilers not supporting pre-processing out of the box.

Subject: Re: [TF-M] Proposal to separate SCT/LD into each platform folder
Hi,
During the level3 prototyping, we found using a unified sct/ld/file would be hard because we are trying to cover platform-specific setting in ONE place.
The biggest concern of preventing spreading the LD is: if there are COMMON changes then every platform source needs to be updated.
I believe the COMMON change is the arrangement of ARoT and PRoT, those platform-specific things such as CODE_SRAM and MPU alignment issue should not be covered inside the common sct/ld/icf.
Not sure if all these format support #include but as we are using a template so it should be possible to put COMMON settings inside a COMMON template and let platform to contain these common part and then add the specific settings.
I have a rough idea (see above) and need more investigation, request for ideas/concerns about this part.
Thanks.

Subject: [TF-M] Proposal to separate SCT/LD into each platform folder
Hi all,
There are many differences in linker scripts between each platform. Using a common_s.sct/ld makes it too complicated.
And at the same time, in order to achieve isolation level 3, the position of the sessions in scatter and linker script file needs to be adjusted.
The common linker scripts would be more complicated with isolation L3.
So I would like to propose to have dedicated linker scripts for platforms with enough differential arrangements.
What’s your opinion on this?
Best regards,
Shawn
Thanks Gyorgy for your inputs.
I haven't checked out the details of all the pre-build processing, but it does seem complex to solve this in a portable way, but one suggestion from me is that perhaps the output from the pre-build processing should be a standard C header and from then on the standardized C pre-processing can be used for the rest of the configuration.
For example, instead of the pre-build step generating producing the final linker script , it could instead generate a C header file which then can be consumed by the linker script. Here only the C header is generated and the linker script is untouched.
This means that, if the IDEs can find a path to generate this C header file somehow (either via IDE configuration or different custom pre-build processing), then rest of the setup continues in a C standard way.
Best regards

Or do you think if we put a specific .sct/.ld under nxp folder would work if there is no other partitions are needed?

Hi,
Good point, this is an important factor. I think templating can be IDE compliant as long as the IDE does support pre-build step(s). The current build flow already contains steps requiring this and thus I don't think situation would be much worse with any mentioned solution than it is today.

Hi Ken,
I think templating is a good approach here, the current C preprocessor based solution is a very limited implementation of this.
I see two main contenders for templating:
1. cmake has built in support for templating with the configure_file() [1] command. This would move ownership of this information info the build scripts, which are the focus point for such info already. A cmake based solution would feel more native to the existing system. On the other hand other solutions might have more features, which could lead to easier to read template files. Also cmake as a template engine is not that widely adopted.
2. jinja2 [2]. A widely adopted and more feature rich templating engine. TF-M already uses it for manifest file handling. I suggest using yahsa [3] instead of a custom pyhton script as the cli frontend though. This could speed up development as long as no complex processing is needed and the templates can be filled based on "simple" values.
Which of the above is the best for the task depends on template file readability and on complexity of the task. It could be nice if a clean split could be made, and we could stop using the C preprocessor based processing completely.
"Not sure if all these format support #include"
The build system works around that by implementing a compiler specific cmake function to add the pre-processing step for compilers not supporting pre-processing out of the box.

Subject: Re: [TF-M] Proposal to separate SCT/LD into each platform folder
Hi,
During the level3 prototyping, we found using a unified sct/ld/file would be hard because we are trying to cover platform-specific setting in ONE place.
The biggest concern of preventing spreading the LD is: if there are COMMON changes then every platform source needs to be updated.
I believe the COMMON change is the arrangement of ARoT and PRoT, those platform-specific things such as CODE_SRAM and MPU alignment issue should not be covered inside the common sct/ld/icf.
Not sure if all these format support #include but as we are using a template so it should be possible to put COMMON settings inside a COMMON template and let platform to contain these common part and then add the specific settings.
I have a rough idea (see above) and need more investigation, request for ideas/concerns about this part.
Thanks.

Subject: [TF-M] Proposal to separate SCT/LD into each platform folder
Hi all,
There are many differences in linker scripts between each platform. Using a common_s.sct/ld makes it too complicated.
And at the same time, in order to achieve isolation level 3, the position of the sessions in scatter and linker script file needs to be adjusted.
The common linker scripts would be more complicated with isolation L3.
So I would like to propose to have dedicated linker scripts for platforms with enough differential arrangements.
What's your opinion on this?
Best regards,
Shawn
Hi Andrej,
TF-M relies heavily on compile time configuration, and C is quiet limited on that. This means we cannot rely on the only standardized part of the "ecosystem" solely, and we have to use non-standard tools. I would love to have a portable automation solution supported by most IDEs.
Yes, a lot of projects can go well with a single configuration header but unfortunately TF-M is more complex than that:
* How could we get information from manifest files to the build?
* How could we generate signed binary packages for the boot-loader?
* How could we control memory map in sync with the hw configuration in source files? (The current pre-processing linker files approach is already non-standard.)
None of these can be solved with IDEs in a portable way. I understand that adding IDE support for TF-M is challenging but the root cause is not how we implemented the build system, but how IDEs can handle the complexity needed by TF-M.

Hi Ken,
So we are using one default/typical configuration. If any change in it, a user have to do changes manually which are not clear without deeper knowledge of the TFM project.
But this is the issue of the TF-M chosen approach - fully rely on cmake preprocessing.
The proposal is to use approach which is good for all worlds (cmake and IDEs) and which is used by all embedded MCU open-source projects like MbedTLS, FreeRTOS, lwIP, FNET and etc.
Which is to have only one set of platform-independent files and the framework configuration from a user/project configuration file.
It will work for both worlds, will solve all configuration issues we have, and will make TF-M easy to use and more popular.
I am talking about this from very beginning. As no steps in right direction, we have a forked TF-M for our SDK.
Thanks George for support ;)

Hi,
Thanks for the input - this should be the goal we are approaching. I believe the updated build system has changed something, and I will raise an proposal based on that during October, let's discuss when the proposal is done.
Before that, two more questions:
* So if a user have to modify the file manually, will they work on the .sct directly, or the .sct.template?
* Does your IDE support pre-build function? What kinds of command it could support? An IDE specific script or general shell commands or python?
Thanks.

Subject: Re: [TF-M] Proposal to separate SCT/LD into each platform folder
Hi,
During the level3 prototyping, we found using a unified sct/ld/file would be hard because we are trying to cover platform-specific setting in ONE place.
The biggest concern of preventing spreading the LD is: if there are COMMON changes then every platform source needs to be updated.
I believe the COMMON change is the arrangement of ARoT and PRoT, those platform-specific things such as CODE_SRAM and MPU alignment issue should not be covered inside the common sct/ld/icf.
Not sure if all these format support #include but as we are using a template so it should be possible to put COMMON settings inside a COMMON template and let platform to contain these common part and then add the specific settings.
I have a rough idea (see above) and need more investigation, request for ideas/concerns about this part.
Thanks.

Subject: [TF-M] Proposal to separate SCT/LD into each platform folder
Hi all,
There are many differences in linker scripts between each platform. Using a common_s.sct/ld makes it too complicated.
And at the same time, in order to achieve isolation level 3, the position of the sessions in scatter and linker script file needs to be adjusted.
The common linker scripts would be more complicated with isolation L3.
So I would like to propose to have dedicated linker scripts for platforms with enough differential arrangements.
What's your opinion on this?
Best regards,
Shawn
Please, do not add changes to sources & linker-files which may harm Non-Cmake systems (IDEs).
Thanks,

Hi Ken,
I think templating is a good approach here, the current C preprocessor based solution is a very limited implementation of this.
I see two main contenders for templating:
1. cmake has built in support for templating with the configure_file() [1] command. This would move ownership of this information info the build scripts, which are the focus point for such info already. A cmake based solution would feel more native to the existing system. On the other hand other solutions might have more features, which could lead to easier to read template files. Also cmake as a template engine is not that widely adopted.
2. jinja2 [2]. A widely adopted and more feature rich templating engine. TF-M already uses it for manifest file handling. I suggest using yahsa [3] instead of a custom pyhton script as the cli frontend though. This could speed up development as long as no complex processing is needed and the templates can be filled based on "simple" values.
Which of the above is the best for the task depends on template file readability and on complexity of the task. It could be nice if a clean split could be made, and we could stop using the C preprocessor based processing completely.

For the record, I have attached the full log of the PSA Arch Crypto test run on AN521.
The SHA of respective repositories are the test run given below:
TF-M - 8f895ab8
PSA Arch tests - ee3c463d
tf-m-tests - 7789423
mbedtls - tag: mbedtls-2.23.0
There is an additional failure for test "psa_close_key with RSA 2048 keypair" compared to the summary report below. This is due to incorrect build flag propagation for changing the ITS_MAX_ASSET_SIZE. This will be corrected in the following days.

Just an update to this,
I have merged the patch which upgrades to the latest mbedTLS tag. The PSA Arch initial attestation test suite fails to build after this merge due to width change of `ecc_curve_t` type. The issue is reported here in PSA Arch test github project : https://github.com/ARM-software/psa-arch-tests/pull/232
The patch for changing the ITS_MAX_ASSET_SIZE is still outstanding and I hope to merge it after a week.

Hi Everyone
The following patch updates the crypto service in TF-M to use the latest mbedTLS tag v2.23.0. All reviews for the same will be much appreciated.
https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5252/1
With this update, additional PSA APIs psa_hash_compute() and psa_hash_compare() are now supported.
There is also another patch for platforms to update the ITS_MAX_ASSET_SIZE when testing with PSA Crypto API compliance test as one of the tests require a larger size: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5253/1 . Could the platform owners review the same and let me know whether the size changes are OK ?
With the above patches, the API compliance remains the same as v1.0 Beta 3 and the PSA Crypto compliance test suite gives the below results (as tested on AN521) :
************ Crypto Suite Report **********
TOTAL TESTS : 61
TOTAL PASSED : 42
TOTAL SIM ERROR : 0

Dear All,
Following the tech forum presentation (back in 6th August) I uploaded the draft design document for the Secure Enclave topic:
https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5653
I also updated the first implementation of the proposed solution for the Musca-B1 board with minimal features, marked as WIP:
https://review.trustedfirmware.org/q/topic:%22Secure+Enclave%22+(status:ope…
Limitations, missing features, notes:
* No support for isolation level2 on SSE-200
* Protected Storage is an Application RoT partition, but PS also moved to Secure Enclave
* Some regression tests running on secure side of SSE-200 fail as all messages are forwarded with the same client ID to Secure Enclave
* All IPC message forwarding is a blocking call
* Only one message is put into the mailbox at a time
* Musca-B1 related documentation is not complete yet
* Generated files are not committed, manifest parser should be run before build.
* The BL0 component mentioned in the tech forum presentation is not uploaded, as it is based on the new cmake system, and not so interesting right now
* Cmake changes are rudimentary, will be rebased to new cmake system.
Any feedback very welcomed!

Thanks, if the different approach for project compilation has its own ld file then we can remove these 4 lines - going to create a patch for this.

Hi Ken,
Guess, these lines where upstream from NXP SDK, which is using a different approach for project compilation.
Most probably they may be removed for the original TFM.
Best regards,
Andrej

Subject: [TF-M] The GNUARM linker script change about psa_client objects and the integration method [NXP]
Hi,
When I was trying to re-arrange the linker script I found below changes:
*psa_client.*(.text*) /* NXP */
*psa_client.*(.rodata*)
*psa_service.*(.text*) /* NXP */
*psa_service.*(.rodata*)
*psa_lifecycle.*(.text*) /* NXP */
*psa_lifecycle.*(.rodata*)
*tfm_log_raw.*(.text*) /* NXP */
I think at least the psa_client.o and psa_service.o are included into the libtfmsprt.a so these items looks duplicated.
What is the purpose of this change? Would it fix build problem or runtime problem?
Thanks.
