Hi Guys,

This issue's still there. Still no RM57 restart triggered by STC test. Any further info about this?

Hello Ke,

After enabling the STC test by writing the STC enable key, the test is triggered only after the CPU is taken
to idle mode by executing the CPU Idle Instruction asm(“ WFI”).

Thanks for the reply
Currently we're using function sl_selftest_STC in safeTILib, which eventually invokes "WFI".

As below:
_SL_Kickoff_STC_execution

WFI
BX LR

Still, no reset after this operation.
