Hooray!!! Rockchip SDK!

[AleMaxx]

1) I have a player with 2608a chip, can I develop for it?

I think so, the folder "RK225_Dict" (in the SDK archive) contains the rk2608 firmware afaik.

2) I am more into modifying the firmware (at least the main menu) as well as developing new applications/games. Is that possible?

The firmware is in there (see above).

3) What compiler should I use? Can GCC for ARM do it?

I havent been working on the rk2608 but I think its a 8051 + zsp400 dsp combo. So you will need those compilers.

4) In what page, in this thread, should I start reading (47 pages are too much to follow)

I recommend reading the source and I think there is a rk2608 datasheet available somewhere.

5) Any instructions on how to compile and build games?

Ask wizard or knob, I think there is some special app available that lets you compile rkp-games.

6) Any instructions on how to compile/build the firmware? I know there is a custom firmware around , where can I get it.

There should be some kind of Makefile or project file in the firmware source so you might just try that.

Thanks for the help.

I still have doubts before go ahead and write something to test on my player:

1) My player does not have a game menu. How can I run .rkp files? The player is based on rk2608a
2) How can I backup my player firmware? I tried the rkusb.tag trick but it did not work for me. Any help?
3) Where can I get the community firmware (binary and source)? Will it work for my player?

rkusb.tag is a trick only for Rockchip 27xx, not for 26xx. If you don't have a backup FW you may kill your player forever. There is a risk that compiled SDK source won't work on your player and you'll be in trouble. Most often there are incompatibilities with screen driver but this can be easily repaired. But some players have very unique keyboard chips or touchpads and it will be hard. I have RK2606 player with touchpad, and after many trails I ran SDK on this player, but touchpad was dead and I still have no driver for it, though I have a working backup so I was able to experiment and return into my original FW.

As far as I know, there is no way to backup your current FW from the player, so if you bought a noname RK2608 player with no FW included, I have bad news for you.

The best I can recommend you is to search through the internet and find whether there is a company which sales exactly the same player as yours (I mean clone), and there are pretty good chance that the FW they provide will work for you as a backup. Nevertheless there is still a huge risk.

BTW. If you don't have game menu, you wont run any RKP files, they requires a new Firmware. Sorry.

Thanks AleMaxx.

Is the only problem of using the community FW the LCD configuration? I can try all the configurations the matches my 2.8" LCD. I believe one will work.

hi guys,

did anyone compiled the SDK with VB yet?

when i try do to so i get this error:

c:\rk27sdk_new\system\os\timer\slist.h(36) : error C2011: '_SINGLE_LIST_ENTRY' : 'struct' type redefinition
1> c:\program files\microsoft sdks\windows\v6.0a\include\winnt.h(857) : see declaration of '_SINGLE_LIST_ENTRY'

I still dont understand the reason why is giving me that...
can anyone let me know

Thank you,

ps - great progress guys... took me 2 days to read all the thread replies lol

The code is in c++. You will need ADS to compile it, you can't compile it with VB.
There is a download for ADS somewhere, might taken another 2 days to find it! lol

well this is what i have as of now


thank you, i was a little confused on how to compile the code...

Good you already have ADS1.2
Install ADS.

Go to C:\rk27sdk_new\Ide\Rk27_board and load rk27_baord.mcp into ADS.
Then hit Project\Make to build it. you will find some errors at first.

Here is my build which should compile fully :- http://www.sendspace.com/file/fjfwpa

Here is my build which should compile fully :- Download rk27sdk_new.rar from Sendspace.com - send big files the easy way

any idea on how to get rid of the errors ?
