I think that too, I read somewhere that this CPU doesn't support MMU, but there are some wicked MMU-like features for better handling SD Card. I am not sure where I read it, but it was some site with comparision of ARM7 and ARM9 which is the main CPU of WIZ game console.

BTW. Does any one know what are the functions in IOMUX for? I am trying to fix the audio problem in my RK2705 player. And all my clues go to this function. But I don't want to waste time if that has nothing to do with audio.

The audio has kind of weak signal, it doesn't work properly if there isn't any addition amplifier connected to the player. Maybe someone know which functions in the SDK are resposible for headphone amplifier?

Knob, and Sid6581 I uploaded IDA project (BASE ORIGINAL.rar) for our original FW. There is huge load of functions in NAME window. If you wish to play a little with IDA Disassembler it will definitely help you.
