SCST Lib test error

Loky

Hi team:

MPU_config() is called before m7_scst_execute_core_tests as mentioned in <M7_S32K3_SCST_User_Manual>. And I find the signature is incorrect value(the value in library is 0x2F6AB216U) in debug mode. But it is correct in run-time mode(without Debugger). I think it is weird. Is it normal?

Hello,

Here is the feedback from SCST team:

I guess that was answered in the email thread, most likely in Trace32 it was set to catch exceptions (BusFault, Hardfault), so it needs to be removed to be able to catch those by SCST correctly.
There is Trace32 command "tronchip" for that.

Best regards,

Peter

Hello,

I expect that this is expected behaviour as debugger can influence the tested parts.

However I have raised this question to the SCST team to confirm/explain this behavior.

I will feedback you ASAP.

Best regards,

Peter
