RockChip mp3/mp4 players

[mortalis]

This is one of the ways to install drivers for windows 7:
 Run command line with administrative privileges and run following commands

• cd "full path to folder where inf, sys, cat files located"
  
  For x64 Win7 you should use drivers in amd64/win7 folder (It doesn't matter that you have intel machine).
  
  
• pnputil -a rockusb27.inf

You also could try to read detailed instruction about uninstalling rockbox  here

I am proud to announce that I've commited dualboot capable bootloader for rk27xx based players.

You probably have this already, but heres an RK Nano schematic: http://www.upurload.com/files/2ee4c33b48f3595bfaccb4d9a183cb1f.pdf

I have lots of RK27xx tools if you want them just ask and ill upload them:

The folder is 65mb worth, and its only 8.55mb in a .RAR
its easy to upload

[wodz]

You mix rk27xx and rknano (which are probably related but are two different things). Nano schematic is known but of little use as it contains only little more then rknano chip itself. Without datasheet and better understanding of firmware file format rknano port is not going to happen.

Has anyone tried this with touchscreen RK27xx players?

Here's exactly the one that I have:

What resolution is your player?
Have you got a firmware backup?

The reference build is 400x240 screen, but without a touch screen driver, I noticed that there are 3 regular buttons on your player which may work.

You need to do make the bootloader and make the zip to unpack on the uSD card, there is no support for flash memory only uSD.

You could try the dual boot with the original firmware, but the screen must be 400x240 or you will need to do the screen driver for sure.

I have a backup and the resolution is 400x240 so those are already covered. I just don't have a micro-SD card at the moment so I have to buy a spare one before I can actually test the Rockchip firmware.

Post Merge: May 08, 2012, 03:21:06 PMDo I use rk27load to upload bootloader.bin to the player? I am just not sure what I use as stage2.bin as it wasn't compiled with Rockbox sources.

For example sudo ./rk27load -e1 -e2 -s1  bootloader.bin -s2 stage2.bin -s3 rockbox.bin

Sorry if I have stupid questions, I just don't want to brick the player.

Do I use rk27load to upload bootloader.rkw to the player?

No need for rk27load just rename bootloader.rkw to BASE.rkw and replace it in the firmware image and flash to player if you have .img file update.

If your player has .RKW firmware update then just open the firmware partition and copy the bootloader over to the player.

Rockbox.rkw and original firmware  BASE.rkw goes in the .rockbox folder on the uSD card then you can do a dual boot, the dual boot works very well and makes updating and testing very easy.


Hope this helps.

p.s. Do you have the original diel-symphony-300 player?

There are no .img updates for this player and it is original Diel Symphony 300.

I'll test the booting as soon as I get the micro-sd card.

Would it be possible to use the internal memory for the .rockbox  folder or is it completely out of question?

[wodz]

Internal memory is not supported and will not be unless someone reverse engineer FTL they used.

Touch version will need some work. All designs I saw use HSADC for reading touch position and currently we don't have driver for that part of the hardware. It should be pretty easy to write one though. Another thing to note is that resolution doesn't matter. What is really important is the lcd controller chip used.

Does anybody found datasheets for RKnano\RKnano-B\RKnano-C ?
i search on chinese websites like pudn.com, docin.com, download.csdn.net, ishare.iask.sina.com.cn and i tried to get documents form IC suppliers on alibaba.
all i found is pin assignment from texet schematic diagrams and thist pdf - http://www.sendspace.com/file/ofldjd
and i have different tools for RKnano.

[saratoga]

Does anybody found datasheets for RKnano\RKnano-B\RKnano-C ?

Just whats been reverse engineered here:  http://rockbox.haxx.se/wiki/RockChipNanoB

FWIW, if thats correct its not a very interesting target since it has too little RAM to do much with.

Hi ! I want to install Rockbox on this cheap (<30$) RK 2738 device smartscreens TuchMe - it is an ebook reader : http://www.smartscreens.com/801/73223.html

It has 800x480 touchscreen and 8 Gb internal flash. It is very similar to this device :
http://www.prestigio-tech.it/products/eBook-readers/3-series/PER3274B

It is possible to run firmware on TouchMe made for PER3274B, but there are some differences in touchscreen driver and battery information is incorrect. There is no radio function in TouchMe.

I was able to use tool for flashing firmware from PER3274B and it works OK, we can flash img files without MD5 checksums required by tool provided by smartscreens.

I have compiled rockbox under my debian wheezy - and the botloader too. Mounted img file, and copied botloader.rkw into system/base.rkw and prepared sd card with .rockbox folder - I have copied there all files from rockbox.zip and original base.rkw.

I have flashed my new img file into device and... system started from /system00/base.rkw not from my sd card

Then I have replaced /system00/base.rkw with rockbox bootloader.rkw and flashed this image into device - reboted and ... device runs in that switched mode waiting for flashing new firmware.

I believe rockbox bootloader.rkw is somehow not accepted by bootloader from original firmware and it can't be executed.

I'm curious why it does not work and how this device boots - some bootloader (uboot?) runs rock2729boot.bin and then /system/base.rkw?

@wodz : what tools did you use to diassemble yours rk 2706 bootloader (Ida?), what do I need to know, if I want to change yours bootloader to run on this rk 2738 devices?

 I have schematic of generic cheap RK 2738 ebook reader from some chinese site. It is probably wery similar or identical to my device. I will attach it here and also rock2729boot.bin.

Is there any public SDK for RK 2729, RK2738 or RK 2808 devices?

[wodz]

273x series is much closer to 280x AFAIK so no, rk27xx port will not work according to my knowledge. There are 3 sources of information available: 1) There are products briefs from Rockchip (which in case of rk2738 states it uses arm926-ejs core like rk280x and not arm7-ejs like rk270x) 2) There is preliminary and incomplete datasheet for rk280x flaying around 3) There are linux kernel sources for rk2808 released by Archos once upon a time.
