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,

Ray

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

Thank you,

Ray

Hi Raymond,

Here is the proposed fix:
https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/6028

Could you verify on your board? Pls use at build -DCMAKE_BUILD_TYPE=Debug for full logging in bootloader.

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.

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 At a minimum, the User Guide is out of date in terms of how the final hex is created.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

Is the latest tested with Musca-B1?
Can I obtain some updated information on how to build and create an image for Musca-B1?

Thank you,

Ray
