Blank screen on the STM32U5G9 board with TouchGFXDesigner

[PoP]

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

1. CubeIDE Version

STM32CubeProgrammer

TouchGFX (last one)

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

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)?
