Hello world,
This is my first post in this forum.

I have the RK27xx based MP4 player, MWalker BL621 (Nebula).
http://www.quantum-optimum.com/mp4/bl621.html

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"

 *** 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.

# 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.

# mount /dev/sdb /mnt/usb/

# ls -l /mnt/usb/

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.

# umount /mnt/usb

About the player.

Pro:
1) It has nice and simple looking look.
2) The UI also very simple with no fancy/animated menu.
3) It has miniSD slot, radio and TV out
4) Plays FLV, MOV, AVI, MP3, FLAC quite well.

Cons:
1) Navigations quite terrible and have to make use of it.
2) It cannot play OGG and MIDI format, even the files are listed in
Playlist
3) Sometimes, it no responsive to any buttons when auto display off and
auto lock are enabled.
4) In the system drives/appdata, there are koules and tank games, but
no GAME menu in UI

Wishlist...
1) Games
2) OGG playback
3) If possible MIDI playback.


Thank you

[toutenkarton]

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" :? 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 :cry:

[makd511]

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???

[toutenkarton]

I tried all combinations, but without restarting the device. I'll try now and replie after that. Thanks for the anwser

[toutenkarton]

Ok I get it working now ! That was idiot from me to didnt restarting the device ... I will now backup the original firmware and than upload to the site for others (but like I sais it seems to be very old).

Thanks again

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:
