Problems with ST-Link multicore debugging of STM32H755ZiQ #1008
Comments

Were you able to resolve this? I would also like to debug from vscode the STM32H755ZIT but cannot get to main of the application or anywhere in the application. get warning "Could not step over: Cannot find bounds of current function (from exec-next --thread 1) |

Hi, I am using an STM32H755 with the extension, I needed to change "-m", "1" in the CM4 config to "-m", "3". As far as I understood, the CM4 is on port 3. |

I'm having trouble setting up the extension for multicore debugging of the STM32H755ZiQ. I don't think the extension has a bug, I'm more looking for hints on how to debug my issues and adjust the configuration to work correctly...
My reference here is your wiki page regarding multicore debugging and this issue. Debugging the CM7 works just fine, but the attaching the CM4 core crashes the gdb-server immediately.
I saw this statement on your wiki page
But unfortunately no hints on how to try to debug this. Would appreciate any pointers on how to debug the issue.
Expected behavior
Launch multi-core debug session
