Bugs in STM32H743I-EVAL Example projects

I bought a STM32H743I-EVAL2 board and updated to the latest STM32Cube 1.8.0 with firmware V1.9.0 and V1.9.1

I tried 2 examples project and they both shows graphics issues.

The example "DMA2D_MemToMemWithBlending" show the 2 first image incorrectly (then the final blending is correct)

The example "DMA2D_MemToMemWithBlendingAndCLUT" is also incorrect with an issue which seems to be related to endianess (the pixels are shown reversed each 4 pixels)

I'm new to STM32 MCU and trying to learn, but if the factory example are not correct, it badly starts.

Also, I saw in some example that the LCD buffer is mapped to an address defined at 0xD0000000 but I can't find anywere how this address is configured ? to which chip is it mapped ? there is so much code that I don't know where to start.

Thank you,

Best regards,

Cedric B

Not sure about the LCD issues, it is not typical that examples don't work correctly.
