jumping to application with watchdog timer

[Prasad_330]

 I am using S32k324

I have bootloader address - 0x4000

I have application address  - 0x50400

I am using the watchdog timer in my application,  which generates the interrupt when the window time period is expired. Now when the window time period is expired i wanted the program to be executed from the address 0x50400 is it possible ??

I tried it but i am getting hard fault once i jump back 0x50400.

Plz let me know wat are the other parameter that has to taken care.

Hi @Prasad_330,

I understand you don't have any problems jumping to the application for the first time, but you can't jump there once the watchdog expires.

Do you jump there from the ISR() or main()?

Jumping from the handler mode can cause problems.

Regards,

Daniel
