My MCU is H7R7, the image type in touchgfx designer only have RGB565 and ARGB8888, no L8 type.

Framework features can not be changed.

What is wrong with that?

Hello ​@amb ,

This is expected. L8 images with an RGB565 palette are not supported by DMA2D. Since STM32H7R7 includes DMA2D, TouchGFX Designer does not offer L8 for this target.
