I try migrate project from RGB888 , that works ok , to L8 - ARGB2222 , but here i have issue, code hang . Changed is only LTDC to L8 and touchgfx part.

When L8 starts result on display is only grayscale without colors.

For simple design i ask L4 indexed palette mode say 4bit per pixel. Is this doable?

Second qustion stay here howto reduce ram usage with 4bit per pixel setup?
