Issue raised in dual core debugging while adding images in the external sdram memory

Shivani · ‎2025-02-11

Hii,

I am using STM32H745XIX6 microcontroller for our custom boards and also enabling the Touch GFX in it, we are doing dual core debugging, and the both the cores got activated and working fine after changing some settings in debug configurations of both the cores.

To check the dual core debugging, I have changed the debug configurations to "Connect under Reset" and selected "Halt all cores" in 1st Core (CM7) and changed the debug configurations to "None" in 2nd Core (CM4).

To add the images in the external SDRAM, I have added the external flash section in the flash linker script. Images that I have added in the Touch GFX are storing in the external SDRAM Memory. Then, I am getting problem in the debugging. What might be the issue?

If I've changed the debug configurations to "None" in 1st Core (CM7) then the debugging after changing the linker file is fine. But only 1st Core is going into debug.

Both the dual core debugging and when storing the Images in the external SDRAM Memory after changing the linker file are not working simultaneously (i.e. Issue in Debugging). I need to work on dual core debugging and also my images should store in the external SDRAM Memory.

Thank You...

What problem, exactly, are you getting?

Hii @Andrew Neil ,

When adding the data in the external SDRAM Memory rather than Internal flash, I am getting debug issue as"Error in final launch sequence"
