unwind stack STM32H7 Free RTOS

[DCorn]

Hi

I would like to store the call stack when the STM32H7 crashes. I implemented unwind.h

The code works on a bare metal  simple est code but not with   FreeRTOS is running

Any idea as to why?

The code

static uint16_t CallStackAddr;

CALLSTACK_DATA uint32_t Address[MaxCallDepth];

_Unwind_Reason_Code trace_func(struct _Unwind_Context *context, void *arg)

{

void *ip = (void *)_Unwind_GetIP(context);

Address[CallStackAddr] = (uint32_t) ip;

if(CallStackAddr < MaxCallDepth)

{

CallStackAddr++;

}

return _URC_NO_REASON;

}

void GetTrace(void)

{

__disable_irq();

_Unwind_Reason_Code ret = _Unwind_Backtrace((_Unwind_Trace_Fn)&trace_func, NULL);

Address[CallStackAddr] = 0xF0F0F0F0;

}
