Hi,

I am trying to flash a single screen Touch GFX application on my STM32F7508-DK board but I got a blank screen.

Did anyone face that problem before ? What could be the solution ?

My actual configuration:

TouchGFX Designer 4.21.0

Thanks in advance!

Do you mean the STM32H750B-DK? Did you press the black reset button? I'm working on this board this very minute. Unlike other TouchGFX projects, this one does not start after being programmed from STM32CubeIDE until you reset it.

No. I think they are different.

I did press the reset button many times but nothing had changed.

Even the examples are not displayed after being flashed. The screen remains blank.

Have you've checked to see if the External Loaders section has a memory device selected?
