LTDC with internal SRAM only - any examples?

Hi, are there any examples available on how to use LTDC in memory-constrained systems (internal SRAM only), L8/L4/AL44 pixel formats (indexed color), CLUT and DMA2D?

I am trying to draw a simple line on DPI LCD connected to STM32F767ZI - so far without a success.
The SRAM memory available on this MCU should be sufficient to drive 800x480 LCD in indexed color mode.
Would anyone care to share his/her experience?
