Hi Raymond,
Could you test this fix, it worked for me:

Subject: Re: [TF-M] Musca-B1 and new build system
Hi Raymond,
I propose the following way to debug:
* I will build and send you a Musca-B1 image based on current master (fc8d2f7 Build: Remove PSA arch tests patch) for testing on your board.
* Please send me both of your images, and if you have the corresponding *.axf files, and if you know the commit-id when they were built.
* I would like to test and debug in my environment.
* By the way do you have a debugger? Can you identify actually what does return an error during security counter init?
BR,
Tamas

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.
Thanks,

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.

Thanks Tamas.
Unfortunately, this did not work for me. Here is what I did to build. Let me know if I did something wrong.
cmake -DTFM_PLATFORM=musca_b1 -DCMAKE_TOOLCHAIN_FILE=../toolchain_GNUARM.cmake -DCMAKE_BUILD_TYPE=Debug -DTEST_NS=ON -DTEST_S=ON ../
cmake --build . --target install
srec_cat install/outputs/MUSCA_B1/bl2.bin -Binary -offset 0xA000000 install/outputs/MUSCA_B1/tfm_s_ns_signed.bin -Binary -offset 0xA020000 -o tfm.hex -Intel
The resultant output is the following.
Entering standby..
[INF] Starting bootloader
[ERR] Error while initializing the security counter

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 At a minimum, the User Guide is out of date in terms of how the final hex is created.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

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.

Subject: Re: [TF-M] New build system missing GNUARM_PREFIX support
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?

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 ?
Best Regards

Hi guys. I'm curious why -fshort-wchar is enabled for ARMCLANG and GNUARM (not IAR, interestingly). This should have little or no impact since wchar_t is so rarely used, and causes incompatibility when I try to link my Zephyr app with TF-M libs.

Hi Antonio,
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.

Thank you.
However, it seems to flash without problem but after reset I don't get the expected output.
The most I can get from the UART is the message "Musca A Firmware Version 3.0" when I power off and on, but none of the logging message expected from tf-m.
Am I missing something?

Subject: [TF-M] Running Tests on Musca-A
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
