Checking for stack overflow

Hi,

I wonder what mechanism I can use to check a stack overflow. My company develops systems that should shut down if anything uncontrollable occurs. We are using the STM32F103 micro controller and dont use an RTOS or alike and write all the code ourselves. Is there some hardware guard to catch a stack overflow?

Thanks,

Henk

Hi,

I managed to construct a function that fills the stack with dummy values and let another function check on change of a stack value at an arbitray location 10 (32-bits) dwords above the lowest stack position and it works fine.

thanks,

Henk
