Hi all,
Currently build of psa arch tests fail for CM55 core of our PSE84 platform
File: api-tests/tools/cmake/compiler/{ARMCLANG,GNUARM}.cmake (same in secure-debug/).
Problem: The toolchain file unconditionally adds -march=... derived from CPU_ARCH. When built inside TF-M, mcpu_features.cmake already sets -mcpu=... with extension toggles. The compiler then sees two CPU specs that disagree on extensions.
Why CM33 works, CM55 doesn't:
CM33: -mcpu=cortex-m33 and -march=armv8-m.main describe the same extension set → accepted. CM55: -mcpu=cortex-m55+nomve+... and -march=armv8.1-m.main disagree on MVE/FP → rejected. Fix (generic): Skip the -march block when an outer build already selects the CPU (e.g. TFM_SYSTEM_PROCESSOR defined, or CMAKE_C_FLAGS contains -mcpu=/--target=). Long-term: switch psa-arch-tests to -mcpu-based selection.
We have not yet pushed PSE84 psa arch tests target, but maybe this can be check by ARM team using one of ARM CM55 based platforms (e.g. Corstone-300 (MPS3))?

Hello,
Indeed, by default PSA-Arch tests adds compile options to avoid it and use TF-M non-secure toolchain only could you add -DTOOLCHAIN=INHERIT option to PSA-Arch tests build?
Thanks, Anton
