I'm working on the IAR part of this and I'm having a problem with the following test in isolation level 3: --- Running Test Suite TFM IRQ Test (TFM_IRQ_TEST_1xxx)...
Executing 'TFM_NS_IRQ_TEST_SLIH_1001'
Description: 'SLIH HANDLING Case 1' ---
If I run the test at full speed, it will run into a MemManage fault while if I single step through the entire test it will pass.
Is there a race condition somewhere in there?
If I disable the SLIH tests it succeeds.
The exception happens when dereferencing "dev" in this function:
bool timer_cmsdk_is_initialized(const struct timer_cmsdk_dev_t* dev) { return dev->data->is_initialized; }
dev is 0x30002440 at the time.
I've been trying to figure out what part of the memory protection system it is that is causing the exception. DACCVIOL is set and MMFAR shows the faulting address.
Ideas?
The build line: cmake -GNinja -S .. -B . -DTFM_PLATFORM=arm/musca_b1/sse_200 "-DTFM_TOOLCHAIN_FILE=..\toolchain_IARARM.cmake" -DTEST_NS=ON -DTEST_S=ON -DCMAKE_BUILD_TYPE=Debug -DBL2=ON -DTFM_ISOLATION_LEVEL=3 -DTEST_NS_SLIH_IRQ=ON -DTEST_NS_QCBOR=OFF
Notice that this build runs into a linker bug in the IAR toolchain and I have a non-released fixed version I'm using, in case anyone is attempting to replicate the issue.
Cheers, Thomas
