M4 Core debug issue

[Harsh_18]

Hi, I'm trying to debug and run simple assembly code in Nucleo-H745ZI-Q board .The IDE successfully builds the program without throwing any errors, However when I try to debug the program CM4 throws the following error:

Error in Final Launch Sequence 

Failed to start GDB server

[KDJEM.1]

Hello @Harsh_18 and welcome to the Community 🙂,

I recommend you to take a look to Getting started with projects based on dual-core STM32H7 microcontrollers

in STM32CubeIDE application note and precisely 3 Debugging chapter.

This chapter highlights some of the points to bear in mind while debugging a device in the STM32H7 Series.

Thank you.

I don't know if it can help in your case, but I found these videos about advanced debugging:
