Find out who is writing to memory address

[MFäh.1]

Hi 

Is there a way to sort of set a breakpoint to figure out which part of my code is messing with a specific memory address in STM32CubeIDE?

I've got this dynamically allocated address that keeps getting changed by something else in my code, and I'm trying to track down where it's happening. Any tips on how I can find the culprit function or module would be awesome :beaming_face_with_smiling_eyes:

Thanks

Depending on the core there's DWT / FPB to watch and break point.

You could instrument flow, and check values in SysTick. Pin down where and when it changes

Create the expression in the expressions window. Now right click it and set a hardware watchpoint. The code will break when it gets modified.

Thank you, this works...

Now, i have to find the problem :-). It seems that it is suddenly being changed at numerous locations in the code, but I dynamically allocated it and have not freed it.

 

Any ideas?
