Any hints on how to provoke the issue?

I can test it with an IAR build.

Cheers, Thomas

 Hi,

We’ve been investigating a problem with the armclang builds for PSoC. The symptoms are that the board just repeatedly reboots. We’ve narrowed it down to commit 300c68da11 “SPM: Use Main Stack for initialization”. This commit is fine with the gcc toolchain but doesn’t seem right for armclang (we haven’t yet looked at IAR). Still digging into the issue, but I figured it might be helpful to give it more publicity.

Hi Thomas,

Thanks for testing. Much appreciated.

The line I’m using (for ARMCLANG) is: cmake -S . -B build_ARMCLANG_Relwithdebinfo '-GUnix Makefiles' -DTFM_PLATFORM=cypress/psoc64 -DTFM_TOOLCHAIN_FILE=toolchain_ARMCLANG.cmake -DCMAKE_BUILD_TYPE=Relwithdebinfo -DTEST_NS=ON -DTEST_S=ON -DTFM_ISOLATION_LEVEL=2

Looks like we have a fix to the armclang PSoC assembly code that I’ll push to gerrit soon.

Chris

I have tested builds with all three tool chains and I'm not seeing any issues.

I had an initial issue with the ARMCLANG build, where it would not boot properly, but after running an IARARM and GNUARM build, the ARMCLANG build appears to work, at least running the regression tests and leaving it running.

Can you provide the cmake command line?
