Hi Raymond
Thanks for the detailed report. This issue was reported here https://developer.trustedfirmware.org/T822 previously but I didn't get time to look into it further due to other priorities. Your analysis seems right and I will look further into this.

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.

Hi,
There is a patch that should allow better configuration of the IRQ tests / other platform-related tests, as well as clarifying the documentation.
https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/6350https://review.trustedfirmware.org/c/TF-M/tf-m-tests/+/6351
Any reviews would be appreciated

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,
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.

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.

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.

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.
