Hi,

It's interesting case. I cannot reproduce the problem with IAR V9.30.1.335 in Windows host using CMake v3.21.7. There are warnings but your configuration builds and all artifacts are installed. I could try install and build using your version later this week.

Hope that helps, Anton

Hi,

It could happen because we have a circular dependency somewhere. Other compilers don't care about this, but IAR could process libraries multiple times. For quick and dirty "solution" you can suppress these warnings, the real solution would be to find the circular dependencies and resolve them. There could be a cmake option for that, it needs more investigation.

Hi

When compiling with IAR bxarm 9.7.1 i get the following linker errors:

cmake -S . -B cmake_build -DTFM_PLATFORM=arm/mps2/an521 -DTFM_TOOLCHAIN_FILE=toolchain_IARARM.cmake cmake --build cmake_build -- install

[25/31] Linking C executable bin/tfm_s.axf Warning[Li065]: duplicate file: "/home/ubuntu/import/source/trusted-firmware-m/ cmake_build/platform/libplatform_s.a" Warning[Li065]: duplicate file: "/home/ubuntu/import/source/trusted-firmware-m/ cmake_build/secure_fw/partitions/lib/runtime/libtfm_sprt.a" Warning[Li065]: duplicate file: "/home/ubuntu/import/source/trusted-firmware-m/ cmake_build/secure_fw/spm/libtfm_spm.a"

In the build.ninja file you can see that all those libraries are includes twice. LINK_LIBRARIES = platform/libplatform_s.a secure_fw/partitions/lib/runtime/libtfm_sprt.a secure_fw/spm/libtfm_spm.a secure_fw/partitions/internal_trusted_storage/libtfm_psa_rot_partition_its.a secure_fw/partitions/platform/libtfm_psa_rot_partition_platform.a platform/libplatform_s.a secure_fw/partitions/lib/runtime/libtfm_sprt.a secure_fw/spm/libtfm_spm.a secure_fw/partitions/internal_trusted_storage/libtfm_psa_rot_partition_its.a secure_fw/partitions/platform/libtfm_psa_rot_partition_platform.a

Is there a reason this is not resolved or this just the way Cmake works? Is there an easy way to resolve this on the platform level? I used the an521 as a template to create my platform.

In my platform this list grows with every feature I activate:

If possible, I want to build without warnings.

Thanks for your help

Kind regards, Nico
