RockChip RK26xx - Porting is now possible !

[MrRockchip]

Porting is now possible! 
Here's a Rockchip SDK with a lot of NEW Rockchip Documents:
Please, go to :
http://mympxplayer.org/rockchip-gdk-game-development-kit-df1003.html

P.S. The name of this download is wrong. It's not only for developing games,
but for everything related to Rockchips.

Hello :-)

But that kind of hardware is very volatile, no? with many variations, etc? no?

I guess that is not interesting to have a port since that hardware is volatile.

Uh? There are several targets out there with Rockchips inside. In what ways do they differ from any other ordinary targets Rockbox runs on?

They are produced just one time, probably. While Ipod and others like have more "stable" versions in market.

Not at all. They are quite the same to us for all practical purposes. An ipod that is out is one fixed specific model that we can reverse engineer and run Rockbox on. A target based on a Rockchip chip is exactly the same.

Ok, I agree on that. But I think there is no point to work on firmware for some hardware that have short life on market. They may have the same IC core but wires to/from IOs are for sure different on each other.

I think Ipods have good support on Rockbox because many people own them and their versions don't change a lot, unlike that Chinese player that are targeted for being cheap, without any costumer support.

That's entirely your subjective opinion. Ports to music players are made by people who own them and who does the work. That work is not done based on what others think is worthy or not.

So, owners of devices with Rockchip internals now have a greater chance to work on putting Rockbox on them than before. That's a good thing. And that may very well be interesting to a whole bunch of Rockchip device owners. Who knows?

Theres actually not much of use in that link.  Its just an SDK for game development and a pirated Microsoft compiler.  Neither seem all that useful.

[MrRockchip]

Actually, all of them are compatible with each other:
a LOT of unbranded players are Rockchip RK26xx based,
mainly RK2608, because RK2606 is outdated.
So, the one port will allow the owners of those no-name players
to launch the Rockbox without any modifications.

P.S. Both Rockchip and iPod are ARM-based

Very good idea I did own Nationite S: Flo with a rock chip 2706

Bump this idea, rockchip players are dirt cheap. Prices (including shipping) are around $40 from dx:

My guess (from comparison with pictures from mympxplayer.org) is that these are all RockChip 26xx players. I've been looking at the SDK and it looks like everything you could possibly want in terms of documentation and code is there. Somebody was saying something about different versions of the hardware, but the SDK includes drivers for different chips like LCD controllers and optional components like FM radio, tv-out, camera etc. A rockchip port could easily be compiled for a given player if its components are known.

These players are dirt cheap but suffer from godawful firmware. Rockbox on a $40 player with miniSD slot would be pretty dope imho.

@saratoga: are you sure you have the whole thing? Because I'm looking at pretty much the entire firmware source, including LCD drivers with TV-out support, and whatnot. Hardware driver sources are in /Rockchip Developer Package/RK27SDK_0722/System/driver. Note things like touchscreen, FM, and sensor (camera).
