Hi Chris,

I agree with you. It looks like PSA arch test doesn’t check the correct clone destination.

According to https://github.com/ARM-software/psa-arch-tests/blob/master/api-tests/CMakeLists.txt#L318, PSA arch test checks whether psa_qcbor exists.

However, the actual clone destination of psa_qcbor folder is under CMAKE_CURRENT_BINARY_DIR as https://github.com/ARM-software/psa-arch-tests/blob/master/api-tests/CMakeLists.txt#L322 sets.

Therefore, I guess this issue will be triggered as long as CMake script execution is in the different directory as binary folder is.

I changed the destination to ${CMAKE_CURRENT_BINARY_DIR}/${PSA_TARGET_QCBOR} in check step and it looks like the issue is fixed.

IMOO, the quick workaround is to entirely remove the build directory.

I will discuss with Raef to determine a final solution.

Thanks a lot for reporting this issue!

Best regards,

Hu Ziji

Subject: [TF-M] Another build issue

This one is a failure when re-configuring the build (even though the configuration is the same):

$ mkdir build_GNUARM_Release

$ cmake -S . -B build_GNUARM_Release -G"Unix Makefiles" -DTFM_PLATFORM=cypress/psoc64 -DCMAKE_TOOLCHAIN_FILE=toolchain_GNUARM.cmake -DCMAKE_BUILD_TYPE=Release -DTEST_PSA_API=INITIAL_ATTESTATION

(lots of output – eventually succeeds)

$ cmake -S . -B build_GNUARM_Release -G"Unix Makefiles" -DTFM_PLATFORM=cypress/psoc64 -DCMAKE_TOOLCHAIN_FILE=toolchain_GNUARM.cmake -DCMAKE_BUILD_TYPE=Release -DTEST_PSA_API=INITIAL_ATTESTATION

(less output, eventually fails)

fatal: destination path 'psa_qcbor' already exists and is not an empty directory.

CMake Error at build_GNUARM_Release/lib/ext/psa_arch_tests-src/api-tests/CMakeLists.txt:324 (message):

  git clone failed for https://github.com/laurencelundblade/QCBOR.git

I suspect that this might be due to the PSA stuff, rather than TFM per se, but it manifests when building TFM…
