This player uses the ZSP400 instruction set I understand, here is the full technical manual,

along with a Beta Disassembler and Assembler,

It's wonderful if Rockbox can run on RK chips. ;D
But people said the RK27 chips are different with RK26, and there is no RK27 datasheet or anything else. Maybe it's more difficult to process the Rockbox on RK27...

Cabewse:
Yes, the RK27 chips are very different. I beleive they are ARM7 200Mhz + Rockchip DSP 200Mhz.

I couldn't find the datasheet, but here's a schematic.

we've done some research on one RK27 OF, we can dispack the OF and get files out. Most of them are media sources such as BMPs,fonts,etc. nothing looks like main process, or maybe main process is made into the chip?

I always think the only thing we can done with RK27 is change its HMI or develop some small apps. And I think that run ROCKBOX may be a mission-impossible. so, it's really wonderful if the ROCKBOX can run on RK chips.  ;D

Hello!
I'm new here. Today I found on mympxplayer.org Rockchip Developer Package. There is firmware source to RK27xx i think (im not sure). Maybe there is any way to make rockbox on it?
Here is link to topic and next 2 linx to package:

Rockchip RK27xx have players like pentagram eon cineo, vedia c6, ramos rm970 etc.
I can't do anything with it because i'm not good in c programming. But maybe your better than me? :)
