STM32F746G-DISCO does not work with TouchGfx 4.22.1

[hbZhao]

Hello,

I just bought a STM32F746G-DISCO from Mouser (Mouser #:511-STM32F746G-DISCO).

When it arrived, the LCD and touchscreen were working well. However, after I downloaded the demo project (STM32F746G-DISCO Control LED from GUI v3.0.6) in the TouchGfx 4.22.1, there was nothing displayed. 

And I tried to import the project into STM32CubeIDE 1.13.2 to build it. The external loader was 'N25Q128A_STM32F746G-DISCO.stldr'. But there was not any luck.

The board is the blue one. The label on the front is 'STM32F746G-DISCO DK32F746G$CU2', and the label on the back is 'MB1191-F746-C01 / C222103562'.

May I know how to generate a WORKING project with TouchGfx? Thanks.

Hello @hbZhao,

Do you have any error while running the demo on target in TouchGFXDesigner ?

What happens if you try to flash your board with another demo project ?

Hello @Yoann KLEIN 

Thanks for your reply. As you suggested, I checked the compiler log. There is not any error.

Also I flashed anther demo project (Intertask Communication Demo v3.0.6), the display is still white.

The interesting is there are some lines which can be seen after programming the project, while it is pure clean if I erase the full flash chip. Please check the attached photo.

The below is the compiler log. And I attach the logs of 'generate code' and 'run target'.

Check build options new boards might use different parts, screen, etc

[hbZhao]

Hello @Tesla DeLorean ,

May I have more information about the build options? The following is the screenshot of the build options in my TouchGfx.

It would be better to have a working demo project, even if it is a single touchable button on the screen.
