Debug of code in ITCMRAM on STMH7 nucleo board

Hi!

I'm developing a software on the STM37H753ZIT nucleo board, I place some time critical functions inside the ITCMRAM to improve performance, the code is correctly running and the behaviour meets the expectations execpt for a fact:

When I place a breakpoint to stop inside a function located in ITCMRAM, the debugger stops in another place:

Here an example is provided, the function placed in ITCMRAM is TIM15_IRQHandler, when I try to stop inside the function the debugger stops in CAN_DeInit, that is a function never called in the code.

Note: Rebuilding and relauncing the project, brings the debugger to stop in another place, different from CAN_DeInit, but still stops in unused code piece. 

 

Does anyone knows why this happens?

Thanks in advance,

Luca
