This time it's now with the 800x480 GLCD driver. It's working, but I'm not sure if the initialization is complete (i.e. the hardware is, most probably, already initialized by the bootloader). I've just modified the sources from Wondermedia (look at "\common\wmt_logo\" folder). LCD routines here are not using the graphics engine (GE) of WM8505.
Read my previous post on how to set-up the tool-chain and how to load the program on WM8505.
