Hi David,
I saw your message earlier, but I did not realize your question was for me, and not for Antonio, I was new to this forum and missed reading your intent correctly. I now believe your question was about the command line I used to build the TF-M sources. I will answer it this way:
- In the Zephyr env: cd /home/zephyr/zephyrproject/zephyr west build -b v2m_musca_s1_ns samples/tfm_integration/tfm_regression_test/ This builds the TF-M's regression test, but in the Zephyr env. - In TF-M build env cd /host/trusted-firmware-m-linaro cmake -S . -B cmake_build -DTFM_PLATFORM=arm/musca_s1 -DTEST_S=ON -DTEST_NS=ON cmake --build cmake_build -- install As I have posted in an earlier message, this fails for the Musca S1 with the "sbrk" issue, but works ok for the MPS2_AN521.
Regards, -Arun.
