TouchGFX on STM32N6570-DK

[Duc]

Hello everyone,

I’m working with the STM32N6570-DK and trying to bring up a TouchGFX project by following the official STM tutorial:

https://www.youtube.com/watch?v=NFljjd_vQGA

I generated the project with TouchGFX Designer and programmed the board using STM32CubeProgrammer exactly as shown in this one:

• FSBL flashed at address: 0x7000 0000

• Application flashed at address: 0x7010 0000

The flashing process completes without any errors.
However, when the board boots, the GUI is completely corrupted. The display only shows colored noise/static like in the video I attached.

It seems like framebuffer data, LTDC configuration, cache handling, or memory mapping might be wrong… but everything was generated by TouchGFX. 

Any guidance would be greatly appreciated.

Thank you!

Hello @Duc ,

For the STM32N6570-DK, we advise our users to use the provided script that is intended for flashing. You'll find more explanation about the flashing procedure in the readme file (located in your project root folder), but in your case, this part is the most important :

We will release soon another version for this STM32N6570-DK TBS where you can flash directly through TouchGFX Designer like all the other TBSs.
