RTOS/CC2640: User call stack from watchdog

Hot snow

Part Number: CC2640

Tool/software: TI-RTOS

Hi,

I am using CC2640 target and CCSV7.

I would like to know if it's possible to have my user call stack info if a watchdog reset was triggered. For example if I call a long delay in my function3 and before the watchdog circuit will reset my system, I want to have my user call stack context or at least the PC info in that time ( if this is possible how to implement it in C code).

Kind regards,

Hello,

Is there any exception handler which stores the user call stack before getting to the watchdog callback function. I managed to get the stack pointer from Task_stat() function, but it contains functions addresses for my own functions and TI-RTOS functions as well, which I am not interested in.

Hello Hot snow,

The watchdog driver does not store any data upon a watchdog expiry. You can use the guidance in this post to store data in a panic buffer upon a reset:
