Hi,

I have a RK27SDK. I tried to use the rkusb.tag file such as renaming this one to "teclast.sys" and "FRK.TAG" but I couldnt succeded.

When i connect the Mp3 player to my computer, i get 2 new external hard drive. In the first one, i have all my commons files like musics pictures etc but when i try to open the second one, windows says me something like "Insert a disk in the drive" Confused So i can't make a backup of my firmware, or trying to flash to a new one (mine seems to be quite old).

My Hardware Id is 080422 and Major Id 1.2.

I'm very interesting about customising this device especially the music player, but i cant' do anything without seeing the hidden partition.

Plz help me Crying or Very sad

Insert a disk in the drive ... this is not the partition it is referenceing the SD card and i assume you have no sd card int he slot

if renaming the file did not work

did you turn off the player after putting the file on the player and then reconnect, did you try all combinations???

hi bahathir

Quote: › As a GNU/Linux user, I were also having problems to access the device. But
luckily the problem has been resoled in the new Linux kernel v2.6.27.

Here is the link/solution to the probolem.
http://bugzilla.kernel.org/show_bug.cgi?id=11423

If you can to acces other DRIVES in the device, you still need to
enable certain feature SCSI module. Here is my simple guide to enable it.

# make menuconfig
Device Drivers -> SCSI Device Support

Enable "Probe all LUNs on seach SCSI device"
Code: › ‹ Select ›‹ Expand ›

*** Some SCSI devices (e.g. CD jukebox) support multiple LUNs
==> [*] Probe all LUNs on each SCSI device
[*] Verbose SCSI error reporting (kernel size +=12K)
[ ] SCSI logging facility



Compile it and use the new module or restart with the new kernel.


Now here is how it looks when I hooked the device to my PC.
Code: › ‹ Select ›‹ Expand ›

# dmesg

Notice that the device has 3 DRIVES.
/dev/sdb - 63MB (system)
/dev/sdc - around 2GB (user)
/dev/sdd - around 2GB miniSD drive.

Now you can mount to the drives. Example: to mount to the device's sys drive.
Code: › ‹ Select ›‹ Expand ›

# mount /dev/sdb /mnt/usb/

# ls -l /mnt/usb/
total 10
drwxr-xr-x 4 root root 2048 2008-05-08 09:47 appdata/
drwxr-xr-x 6 root root 2048 2008-05-08 09:47 resource/

drwxr-xr-x 2 root root 2048 2008-10-31 22:27 system00/



Before removing the device, please do and wait until the umount
command finished. Code: › ‹ Select ›‹ Expand ›

# umount /mnt/usb
#

Thanks for this information, sorry i didn't see this before, I've got Linux as well as XP so I'm gonna try this out!

So basically it means we can access the firmware partition directly from Linux without playing with rkusb.tag. Thanks, this is gonna come in VERY useful.

Thanks you very much for sharing this information Wink

ATTENTION!!!

Here the solution at the problem of the two devices!!!
If we copy the file rkusb.tag into the root, restart and connect it to PC, we can see 2 devices,
but if you delete the file rkusb.tag, at the next restart the second devices (the hidden partition of the system files) doesn't disappear!...
This happens because we must replace some system file before deleting rkusb.tag!!!

Go to /Resource/BID of the hidden partition
I tried to copy BMP0.BIN on my PC, then I've deleted BMP0.BIN in the folder, then I've modified BMP0.BIN (changing some images with RK27UIEditor2) and recopied this BMP0.BIN from the PC to the folder of the hidden partition.
Then I've deleted the file rkusb.tag, disconnected the MP5, so a red screen appears, because it's changed some images, and finally I've restarted the MP5 ...
So with the next connections the hidden partition disappear!!!

For the download... I didn't know that I had to wait a bit... '^_^ sorry!...

However... putting the solution of the 2 devices at the end of the guide in the first post isn't a bad idea... no? Wink

If this doesn't happens, you tried to modify the file BMP0.BIN changing some image before the "recopying" onto device! Wink


DOES NOT WORK!!!!!!

Dingchow, have you tried to modify the file BMP0.BIN before replacing in the hidden device???
Because if you delete the file rkusb.tag, and then replace the modified file BMP0.BIN, at the disconnection and the updating of the library (before the restarting), you should see a red screen!!!
If you don't see this, you haven't correctly done the procedure...

It was kinda hard to understand. I did not edit the BMPO.BIN file and did not see red screen. I cant find RK27UIEditor2 to download it. You have a link for it?
