Blank screen on the STM32U5G9 board with TouchGFXDesigner

I am working with the STM32U5G9 board and I have some trouble when displaying applications 

 

As indicated in the tutorial (link below), I installed the 4 applications. I took the last ones from ST website.

CubeIDE is already installed since I work with TOF sensors quite regularly

Here are my application versions.

  1. CubeMx Version

In CubeMx, I add the TouchFX Generator

After setting CubeMx, I followed the tutorial below

With the configuration

In TouchGFX Designer, I can simulate my application

Unfortunately, in the CubeIDE step When I compile the project and upload the compiled application, nothing happens on the display (blank screen).

From CubeIDE, I'm able to load the tutorial application and debug it by stepping into the code.Unfortunately, in runtime the display remains black.

This is the same cases for all demo in TouchGFX except only 1 demo (Flash limited E-Bike demo), 

Otherwise, I get a black screen for the other demos.

I don't know where I am wrong

This is confirmed, this is a trouble with the STM32U5G9J-DK2, ES Version.

With the official release version of the STM32U5G9J-DK2, we don't have anymore problem to upload any application.

I did not have the good board version.

Hello @PoP ,

Are you able to run on target from TouchGFX Designer?
Have you tried to reset your board (clicking the reset button on the hardware directly - or plug/unplug the cable)?

Thanks for your help but this is not so much easy.

The environment is correctly installed because applications are working well in the Touch Designer environment.

After discussion with a ST Field Engineer, it appears that the trouble is coming from that the board STM32U5G9J-DK2, I have is an ES version.

On this kind of board, the blank screen was reproduced by the ST Field Engineer. I am waiting an official board of the STM32U5G9J-DK2 (not ES version). I'll tell you if it works better and if the problem is fixed

Great to hear that your issue has been solved with the official board and not the ES version. May I know where did you get it from?

I am facing the same issue on 2 out 10 STM32U5G9J-DK2 Boards I have bought 5 months ago. How can I check out the board version (ES Version or official version)? Is there any indication referring to the board version?

Normally our ES have this label printed and sticked on the board itself, like on the shared picture. Have you bought your boards (including the ES boards) from our store or from another supplier?

Thanks for the prompt reply!

I have purchased the boards from Mouser. According to your feedback, the boards do not belong to the ES category. Let me restart all the tests. I'll come later back to you. Maybe there is another issue I am overseeing..

Unfortunately I am still facing the same problem on one board. I have started a small TouchGFX application. After downloading the application into the Flash memory, the board has been properly restarted.  Every thing went smooth and no error has been reported. But the display remained blank. 

@DILK have you tried to debug and see what happens in this case? What do you use to compile your project? and for flashing?
