We are currently developing a product that involves the DSI host interface. We were successful with the STM32F469 disco but we aren't having any luck with a custom solution. We are using the same series chip for our custom board as the discovery kit. Attached are schematics, the CubeMX,IDE and toughgfx project files and the datasheet for the screen. The person doing the UI for the project told me that I wouldn't need external ram (which I almost added anyway) to run his program so that's why there isn't any external RAM on this board. So I guess our main questions are:

You'd need 1.1 MB of RAM for the frame buffer (480x800 24bpp)
Perhaps you can make a test pattern with less.

I think it's at 200 X 400 16 bpp right now
