Cant swith Touchgfx RGB888 to ARGB2222 config . Next question, howto setup framebuffer 4bits per pixel?

[MM..1]

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?

I reply for first question myself. For changing and generate new config before edit ico need manualy erase all files from folder target, because cubeMX refresh generated target files, but not target files and here place CLUT init...

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