Issues Setting Up TouchGFX Project for STM32N6570-DK

[TerZer]

I’m running into some trouble when trying to create a new application with TouchGFX Designer version 4.24.2 on the STM32N6570-DK board. After generating the code and opening the project in STM32CubeMX, I encounter a clock configuration error. It seems to resolve itself automatically, but the real issue starts when I move to STM32CubeIDE.

In STM32CubeIDE, I get an error saying the .elf file does not exist. When I try to build the project, I encounter numerous errors like "bad instruction" in tx_initialize_low_level.S.

Has anyone successfully set up a TouchGFX project for the STM32N6570-DK? Any guidance on how to resolve these issues would be greatly appreciated!

Thanks in advance for your help.

Hello @TerZer ,

I have reproduced the steps you did :

1. Create a STM32N6 project from TouchGFX Designer
2. Generate code from TouchGFX Designer
3. Open STM32CubeMX and generate code to fix the clock issue
4. Open STM32CubeIDE and try to build the application

I do get multiple error when building on step 4, however, I am able to fix these issues by going back to TouchGFX Designer and regenerating code between step 3 and 4.
After generating code from STM32CubeMX, you should re-generate code from TouchGFX Designer aswell.

If this comment solves your issue I invite you to select it as "best answer".
Hope this helps!

Hi @GaetanGodart ,

That helped, but now when I run the application, I get the following error: "Could not verify ST device! Please verify that the latest version of the GDB-server is used for connection."

Here’s the full console output:

It seems like the debugger cannot read memory. I also noticed that using STM32CubeProgrammer, I am unable to read memory after running the application. However, after unplugging and reinserting the cable, I can read memory again.

Any ideas on how to resolve this?
