TouchGFX Not working STM32F746G-DISCO

[janid_a]

I am facing some problems with TouchGFX 4.24.1.

After creating a project from Demos -> Board Specific Demo and selecting the STM32F746G-DISCO, and selecting the project: STM32F746G-DISCO Control LED from GUI. I got two problems:

- Problem 1: Frozen Screen and incorrect display of toggle button and light icon
Program and Run Target "F6", After flashing it

The light toggle button is not showing correctly and not interacting from the touchscreen.

- Problem 2: incorrect display of toggle button and light icon

After opening the project with STM32CubeIDE 1.16.0, compiling and running the project. It interacts but the LED icon and the toggle button are still displaying incorrectly.
(I have faced the some problem also with 1.16.1, but since TouchGFX suggests software tools CubeMX 6.12.0 and FW 1.17.2)

- Problem 3:  Program and Run Target "F6", with TouchGFX fails sometimes

Can anyone help me to get TouchGFX running properly?

Thanks

Hello @janid_a and welcome to the community!

 

I have been able to flash the demo on a STM32F746DK board.
Can you try to flash it again?
What happens when you flash from STM32CubeIDE or from STM32CubeProgrammer?
Can you test other demos?

[janid_a]

Flashing using the programmer or the IDE both running and Debug mode results in Problem 2; It is possible to interact with the toggle button by turning off and on the pool light , but the icons are not displayed correctly (Green and ugly).

I tried generating other demos or examples from the TouchGFX by specifying the Board, generating the code, running to target and they don't work!! (Also by opening the project with STM32CubeIDE).

 

[GaetanGodart]

Since it works on my side and it doesn't work for you on other demos and IDE, I would assume this is an issue with either your computer (compiler, dependencies, etc) or with your board (previous surtension, static electricity, etc).

Can you try on a different board or computer to try to isolate the issue?

Hello @janid_a and @OU_it ,

 

We will create a new TBS (TouchGFX Board Setup) for this board revision (C0 and newer).
I will notify you once it is available.

Hello @janid_a and @OU_it ,

 

The new TBS revision (3.0.23) is available :

Hi @GaetanGodart. Can tell me what was the main issue?
Thanks.

[GaetanGodart]

There was a new board revision with a different memory.

 

Regards,

[GaetanGodart]

Hello @janid_a ,

 

The issue occurs because that board got a new revision, it's memory got changed.
A new TBS (TouchGFX Board Setup) is available in TouchGFX Designer, therefore you should not face the issue anymore.
