Program Stuck In DefaultISR

chaitanya_kalyani — Wed, 10 Mar 2021 12:55:26 GMT

Hello,

We have developed board for one of the project and using S32K118 MCU but when I am trying to flash the program then it is getting stuck in ISR. For programming we are using PE Multilink Fx.

For every program it is having same issue. It is entering in DefaultISR only.

when I write HardFault_Handler then it is entering into the function.

void HardFault_Handler(void)
{
while(1){}
}

Debugger showing bus fault message

BusFault: A bus fault has occurred on exception entry.
BusFault: An imprecise (asynchronous) data access error has occurred.
HardFault: A fault has been escalated to a hard fault.

Is it hardware issue or software issue.

Quick response highly appreciated.

Hello @chaitanya_kalyani,

Does it happen also with examples from the IDE or with a new empty project?

Can you show the debug configuration?

You can try to halt it at SystemInit() instead of main() and step the code.

Regards,

Daniel
