Behaves the same with IAR.

Build command is:
cmake -S . -B output -G"Unix Makefiles" -DTFM_PLATFORM=cypress/psoc64 -DTFM_TOOLCHAIN_FILE=toolchain_GNUARM.cmake -DTEST_NS_MULTI_CORE=ON -DTFM_ISOLATION_LEVEL=1
The result is a hang at this point:
Executing 'MULTI_CLIENT_CALL_HEAVY_TEST'
Description: 'Multiple outstanding NS PSA client calls heavyweight test'
Totally 5 threads for test start
Each thread run 0x20 rounds tests
Some experimentation shows that:
It happens with both gcc and armclang (unable to test IAR).
It doesn’t always happen, but does seem to hang more often than it succeeds.
It doesn’t happen with TFM_ISOLATION_LEVEL=2.
It looks like this test was passing consistently before 5e68b11764673ee32bae0de8ecf3cde45cc55ea1, so I guess this is another scheduling issue. There’s not a lot of code that differs with TFM_LVL, so I wonder if there’s a race condition that is always present but just doesn’t happen to get hit at TFM_LVL=2…?
BTW, being able to build just the one test is extremely useful!
