Has anybody already tried the new CubeIDE 1.4.1 and Touch GFX 4.14, I cannot get it working.

Question

I did start the project with F469I Discovery board, I got all the settings then I add Graphics Application it generates new folder TouchGFX.

I start from this folder TouchGFX, I build simple screen, generate code.

then I build the projects no errors I upload to the board.

dark screen, nothing there.

am I missing something ?

I got all the same setting for LTDC like RGB888, 800 x 480 pixels form other working project I ma sure I am not missing anything here

how do I set it up so it works ?

Did you upgrade CubeMX to 6.0.0 as well? I experienced the same issue after any change to the .ioc file. If a program is generated in TouchGFX and then run right to the target F469i-Disco board, it functions. I can also open it in Cube IDE 1.4.1 and run or debug it as well. However, as soon as any change is made to the .ioc in Cube IDE (version 6.0.0 of CubeMX), it states that the version of the MX file is 5.5.0 (the one generated by TouchGFX 4.14.0) and it needs to be migrated or an older package is required F4 V1.24.2. Either way, as soon as any change is made and new code is generated from the .ioc file, both migrated or not, the program no longer displays anything. This happens both with TouchGFX "Run Target" and either Debug or Run in Cube IDE 1.4.1. Not sure if you are modifying anything in CubeMX 6.0.0, but that appears to be the issue I am experiencing. The workaround is to modify the .ioc file in CubeMX5.5.0. I installed a separate instance of CubeMX 5.5.0 and load the .ioc into that instance to liberate my peripherals. I then generate the code and exit. I am careful not to open the .ioc file in CubeIDE after that. Maybe you will find something in here helpful.
