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.
STM32CubeProgrammer
TouchGFX (last one)
In CubeMx, I add the TouchFX Generator
After setting CubeMx, I followed the tutorial below
https://www.youtube.com/watch?v=NFljjd_vQGA&list=PLnMKNibPkDnF9x-s1e-v9Wtvv-fB88VWA&index=2
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
Solved! Go to Solution.

&^)$^(^*^#$&^%* This is example of your info. You write on one board , is this info on second board same code shows display ok etc. @Osman SOYKURT info about not working demos on ES is fine, but more better is info where make change to ES go working... On my planet result for action is reaction

Hello @MM..1 ,
I don't know about the differences between the "ES" and "official" board, but I think ST's quality department may have the answer. We wrote this in our User Manual :
"Parts marked as “ES” or “E” are not yet qualified and therefore not approved for use in production. ST is not
responsible for any consequences resulting from such use. In no event will ST be liable for the customer using
any of these engineering samples in production. ST’s Quality department must be contacted prior to any decision
to use these engineering samples to run a qualification activity." .
I'll also try to look for the differences on my side and message you back if I find anything interesting
