Been speaking behind the scene's a bit with Ker Nel and I gave him the Rockchip RK26xx datasheet's he's posted them up:

I suggest we all start to look closely at this chip and lets start to see about how we could potentially get a Linux kernel onto it, remove its proprietary OS and look to get Rockbox onto it as well as other apps.

This chip based on the pair of RM100's I've taken apart and from the datasheet seems to be unbelievable powerful, so now lets see how far we can take it !


Rock On !!!

Rockbox does not depend on a linux kernel.

The datasheet doesn't say anything about a ARM core and the assembler instructions in the examples suggest it's MIPS based I think. I couldn't find anything on the "shll.e" instruction. Doesn't look good.

Laserboy:
hey guys i found this form mympxplayer.org seems like a way (risky thought) how to edit the firmware off rockchip players... but like it says there seems to be no way of actaully extracting it for editing.... how this helps

Here is a clue into the onboard Codec of some of the Rockchip processors:

http://www.dolphin.fr/flip/analog/analog_overview.html
http://www.dolphin.fr/corporate/announcements/publications/pdf/rockchip.pdf

From both pages: "Our CODEC is embedded in Rockchip RK2606" someone might be able to glean some info from Dolphin Integration for programming information (like what happened with AustriaMicrosystems and their AS3514 chip).

Edit:
I just found a rar of the Rockchip USB driver and what seems to be the firmware update program:

Edit (again):
I just found this also, its a page with a very large driver collection for all your cheap Chinese electronics (I even own a few of the listed devices ;) )
