STMF469I DISCO TouchGFX demo problem

[olivier.scalbert]

Hi,

I have compiled and load the demo to the board with STMCubeIDE 1.4.0 on Linux.

When I start the board, it seems that the display is correct during a quarter of second or less.

Then the colors are getting weird, like if there is a palette problem.

Does anyone have the same problem?

Thanks,

Olivier

I can see that you didn't use the Application Template for F469-DISCO board available in TouchGFX Designer.

We create these Application Templates to help users start off with a working project. Please try with the Application Template and check if it works.

Hi Alexandre,

As I am on Linux, generating a project from TouchGFX Designer is not an option.

That is why I generate the project by using STM32CubeIDE (New project / Example Selector / ...).

This approach works well for the STM32F769I DISCO board. I see no reason why it should not work for the STM32F469I DISCO board, as it is proposed by ST.

​Generally, working with TouchGFX requires the Designer, but when you're using CubeIDE to run an "example" this comes out of the Cube Firmware pack for said MCU. It should definitely work, but the issue with the "examples" is that they don't follow the general updates we have for a specific board. I'll look into this.
