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

Hi,

Please provide more details. Images, videos would be great.

Thanks!

Here is a video where I reset the board several times.

Sorry for the bad quality !

[Martin KJELDSEN]

Looks like, among other things, the external flash hasn't been programmed with any images. Can you verify?

[olivier.scalbert]

First thanks for your help !

I am more a vim/emacs makefile guy, so I am not comfortable with ide ...

After the "build", I press "run". I get this on the console:

Should I do something else ?

[Martin KJELDSEN]

Nothing in there says anything about programming the external flash (starts at 0x90000000)

Can you try choosing the right flash loader in CubeProgrammer? Try using the stand alone CubeProgrammer application.

[olivier.scalbert]

Ok, I have installed CubeProgrammer, select the External loader.

Things are better but not fully ok. Here are the logs and a photo of the main menu.

Note: it is compiled in debug mode.

For your info, I have done the same thing with the TouchGFX demo for the STM32F769I Disco and it works well !

So my setup seems ok.

Hello,

Can you send your project ? It will be easier if we test on our side.

Please remove all unnecessary folders like the build folder in TouchGFX/ folder and touchgfx middleware folder so that your project is not too large.

Here t is ...

Sorry for my late reply ...

[Alexandre RENOUX]

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.
