STMF469I DISCO TouchGFX demo problem

olivier.scalbert · ‎2020-10-30

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 !

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

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:

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.

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.
