I figured that the while statement was there for debugging :)

Sorry for typo mistake. I will rewrite the code again:

int main(void)
{
register uint32_t __regProcessStackPointer  __ASM("msp");
     stackStart = (uint32_t )__regProcessStackPointer;
     stackEnd = stackStart - 0x800; //stack size 2048
  while(1)
{
  ////
}
return 0;
}

uint32_t getRemainingStack(void)
{
    uint32_t currentSP;
    uint32_t stack;
    register uint32_t __regProcessStackPointer  __ASM("msp");
     currentSP = (uint32_t )__regProcessStackPointer;
     stack = currentSP - stackEnd;
    return (stack);
}

Hi Aryan,

I found that Keil startup files do not expose the stack nor the heap location in memory. Till now the solution i implemented is:

int main(void)
{
register uint32_t __regProcessStackPointer  __ASM("msp");
	 stackStart = (uint32_t )__regProcessStackPointer;
	 stackEnd = stackStart - 0x800; //stack size 2048
}

uint32_t getRemainingStack(void)
{
	uint32_t currentSP;
	uint32_t stack;
	register uint32_t __regProcessStackPointer  __ASM("msp");
	 currentSP = (uint32_t )__regProcessStackPointer;
	 stack = currentSP - stackEnd;
	return (stack);
  while(1)
{
  ////
}
return 0;
}

To get the stack usage periodically, getRemainingStack handler is called by app timer every 10ms. It is polling method. but idea was have get an exception whenever stack overflow happens.

Thanks

I will have to try this out in my leisure time, hope someone who has already tried this gives us an answer.
