WDOG_IRQHandler() at startpup issue

[pankajprasad100]

Hi,

We have a code from the ref-Solved: S32K SDK LIN Stack not working properly with UDS - NXP Community

In the above ref code we just changed the Enable and UART pins and flashed the code and after some time we get interrupt from watch dog.

What you can suggest so that we can avoid the interrupt.

Hello @pankajprasad100,

This is probably a Hard Fault exception.

Please implement HardFault handler in the project and try to debug it as explained in this thread:

Thank you,
