S32K146 Application layer codes stop at DefaultISR:

[609510318]

When I debugger the S32K146 board,my application layer codes stop at  “b DefaultISR” after running for a while.How can I solve this problem?What is the reason?Thanks.

DefaultISR:
b DefaultISR
.size DefaultISR, . - DefaultISR

Hello,

Could you, please, specify the line/ function after which triggers DefaultISR (when you debug the code)?
One of the reasons could be that you do not configure the clock for some peripherals.

Best regards,
