S32K144 SCST fail when interrupt nesting happen

[stanley_wu]

Hello, we run the SCST in Thread Privileged, but the test always will be failed after several minutes system operation. If we set all the interrupts with the same priority, the SCST will be passed. So it seems like the interrupt nesting has impact on the SCST.

Could you explain if there is a conflict between interrupt nesting and SCST? And how to solve this problem?

Thank you in advance!

Hi Stanley,

To avoid problems with nesting, the solution is to run the first group of tests (TestID 0-15) with disabled interrupts in the NVIC controller. Second group of tests (TestID 16-43) can be executed without any restrictions.

Hope this helps.
