    Which one did you take? I never tought that I could use the same kernel for linux and android...

    The first one is not working (screen blinking) like in picuntu... The finless is working (for now) and I'm installing right now ubuntu from the xubuntu package.

    Latest update: first one not working, blinking screen like every kernel from picuntu... finless is working but far too more limitations because of the android security. I have no choice but go back with android until linux is far more mature. At first I wanted a linux desktop with my MK908... but right now, I'm hesitating, android with the coming of andropen office and xbmc... seems to me a good contestant for any desktop linux.

    TY!

    I tried to install it too but whenever it's completed in Rom Flash tool it's not booting... you seem to have been able to install it on a mk908 v5 which I have also. Did you do it through Linux? What steps aren't I doing?

    This is what I did:
    • Downloaded Kernel 720p MK908 from https://disk.yandex.com/public/?hash...CxQoP%2BN00%3D
    • Downloaded Xubuntu stuff from the same site
    • Double click on Rom_Flash_Tool.exe and changing kernel to the one downloaded.
    • Tried the following systems:
      • first checking system-install that is already included but unchecked.
      • secondly I tried an to install that system onto a sdcard (win32diskimager) and reflash everything without checking the box.
      • thirdly checking with the linuxium-ubuntu that you talked about (I'm currently installing it)
    • I also tried to flash a recovery kernel (that was mentionned on the site Yandex as out-imagetext-recovery but still nothing on my screen from another tool (since in the tool offered in the xubuntu package there's no recovery))
    • I changed the original Loader for the xubuntu package to the Finless Rom 1,7a loader since it was said in one post that it could help someone to take the last one.



    Since I see no output, I cannot know where resides my error and what I have done incorrectly however, maybe by reading me, you'll know what might be wrong

    THanks and have a nice day.

    on my mk908 v5, but it can't load in graphics interface. I've got a message like "system run in low graphics mode" and no ubuntu desktop appears.
    How can i fix this? It is neccessary to install video driver or something else?
    Now i can boot into command line, and it's working ok, but x-server do not start.

    upd:
    If i break down to command line with Ctrl+Alt+F1 and run 'startx', i get a ubuntu-like desktop with same color background, but no menu's and so on.

    Hello,

    Picuntu has been running real smooth for weeks on my hdmi dongle (RK3188). Yesterday I needed to shut it down, and now it won't startup anymore.

    Using the same power supply, when I plug it in I can see the lue led lighting inside the plastic case, but it's not booting. No output on the HDMI. If I plug an USB optical mouse before the power supply, I can see its light for a fraction of second. But nothing more.

    Is it a known issue? What do you suggest? Should I try flashing the kernel again? Or flashing everything again (I would rather not as I have spent hours in configuring all the needed services, and didn't do any backup)? or do you believe it is definitely bricked?

    Succesful Install on T428 - but now cannot reflash?

    I sucessfully installed on the T428 using - It is amazing !!

    Here are a few of my findings:

    1. Internal WIFI and Bluetooth not recognised. External Bluetooth device also doesn't seem to be recognised ( I installed bluetooth manager, no adapters found)
    2. External USB Wifi recognised (DLINK DWA 140 ) but still working on trying to get it to work.
    3. Sound worked out of the box via HDMI.
    4. External USB Sound card is recognised , but it is not producing any sound (I selected playback of the recognised device in the pulse audio mixer, unmuted, mixer volume max - still no sound) : update - uninstalled pulseaudio, then reinstalled it and also included all recommended and suggested packages, then used pulse audio volume control and voila ! USB sound :-)
    5. Cannot install Skype (architecture problems). I had hoped to at least get audio with skype but no success.
    6. Of course MALI accelerated graphics not supported.
    7. Firefox and chromium worked fine, most flash video sites don't work. Limited success with youtube in firefox using gnash. Very choppy.
    8. Playing Videos (even low res) with Parole is very choppy full screen, have to have a very small window to play sort of smoothly.
    9. Playing videos with gnome mplayer - will only play in a small window.
    10. Libre Office works great.
    11. Overall a very 'snappy' peformance, amazing , eventually this will become a full blown replacement desktop, well done to all !!

    Now I have had a good play with it I want to go back to Android, at least for now as there is still work to be done with teh linux system. However my stick is now not recognised at all by my Windows PC. I had no problems before flashing to picuntu. The stick is just not recognised at all i.e. no usb sound, no new drive letter, just no reaction at all from the PC or Rockchip Tools software (even with the flash/reset button pressed). I have flashed and reflashed this stick hundreds of times before, this is the first time I faced this problem.

    Any advice anyone?

    Many thanks

    Yes, I am experiencing the same problem. I have posted a issue on this on alok's github. If anyone else has the same issue please post it in that issue on github to make alok aware of this bug.

    First of all, a huge thanks to Alok, as well as the entire PicUntu team and community members, for your hard work in getting PicUntu onto RK3188 devices!

    Following the postings from gmtii and alok's response, I've re-compressed a version of the installer 7z (DOWNLOAD HERE) which contains an updated system.img that includes Omegamoon's 3.0.72+ kernel modules (/lib/modules/3.0.72+/ folder copied from gmtii's archive, /lib/modules/*.ko.3.0.72+ compiled from omegamoon's git repo), as well as gmtii's compiled kernel_nand.img and kernel_sd.img. I hope that this can allow more people to try out PicUntu on their MK908 devices!


    Flashing Instructions (derived from Alok's; tested on MK908 v3):
    0. Make sure you have the Rockchip device drivers installed on your Windows PC. You can use Google to find instructions. Also, read Alok's original post before continuing.

    1. On a Windows PC, download and uncompress PicUntu-4.5-BasicGUI-Nand-MK908v3.7z.

    2. Run rk_flash_1.37/RKAndroidTool.exe. Every entry except for misc, recovery, and backup should be checked.

    3. Disconnect all USB connections to your MK908 device; make sure a USB-to-mini-USB cable is connected to your PC.

    4. While holding down the reset/flash button (accessed via the small hole near the HDMI jack that does not light up during normal boot-up), connect the mini-USB cable to the side mini-USB jack (labelled OTG). Hold for 2+ seconds until RkAndroidTool.exe reports "Device Found for Flashing". (If this does not happen, make sure you have the Rockchip device drivers installed)

    5. Click on Erase NAND and wait until messages stop (~20 sec)

    6. Click on Flash ROM and wait until messages stop (~3 mins)

    Currently, you need to manually load the wifi module on every boot, although you can probably create an upstart/init.d script/cronjob/etc. script to do this automatically.

    7. Once you log into PicUntu, open up a Terminal (2nd icon in the bottom launchpad).

    8. Type 'sudo insmod /lib/modules/rkwifi.ko.3.0.72+', and enter password when prompted.

    (Edit: there seems to be a permission issue after running this command, where only root user can access internet -- ping/ssh/apt/wget/firefox/etc all fails under picuntu user. Try removing the sudo when running the insmod command... I have yet to test this since I'm in the middle of compiling.)

    9. Enjoy PicUntu on your MK908 device!


    I'm in the process of configuring a MK908 to control an AR.Drone quadrotor autonomously using OpenCV and ROS. More on that soon (I hope)


    Sidenote: to find out what is the board version of you MK908, you need to open the case (by slowly propping it open using a spadger/ flat screwdriver/etc), and look for the text "MK908 V3.0 2013/05/13" on the side with the reset/flash button, near the OTG mini-USB jack.


    P.S. to Alok: in RkAndroidTool.exe, you can right-click on the list of items and export an updated flash configuration into config.cfg

    MK908 - Wifi stops after some time

    Thank you gmtii. Your kernel here works really well. I flashed it onto my mk908v3 and now it doesn't have the problem with requiring root for network based activities (i.e. firefox/chromium).

    A new request for your: Is it possible to compile a kernel with 1920x1080 output?
    I successfully installed picuntu on my mk908 too (not sure which version), managed to have wifi module loaded at boot time (just had to move the file in the right driver folder for 3.0.72+), without root required for firefox/chrome, but know the wifi stops itself after some time (some hours, haven't checked if it's always the same amount). Does anyone with a mk908 have the same problem ? And maybe a solution ? ^^

    I want to use it as a little web/dev/files/scripting server, so a stable wifi connexion would be usefull

    Anyway, thanks a lot for all this work !

    It works!

    Today i flashed image ubuntu-12.04 from whis post http://www.gizfun.com/content/instal...ksmk908mk802iv in 'system' block of nand
    Then i've resized root parition with commands (i've took this command from rc.local of vmkogeretla's image, thanks to him )
    Code:
        resize2fs -p /dev/mtdblock2
        mount -o remount,rw /dev/mtdblock2
    Now i have almost 8G of disk space, and 75% free space;

    For installing applications (like chromium) you need update packages with

    Code:
    apt-get update
    Works fine, no resets, no hangs.


    But color depth is low, i think it 16bits per pixel. Is color depth configured in kernel or somewhere else?

    Hi, now i have reinstalled picuntu for mk908 distr. It loads and works, i have installed some software like vsftp and apache2. And it works ok too.
    Also i need some application development. For it i have installed QDevelop via Synaptic Package Manager.
    And i have it cruhes when building project from IDE, if i build project from console, it builds ok.
    Error - "segmentation fault" when builing from IDE.

    Second problem - device suddenly reboots. My suggestion - is overheating, but i run stress utility, wich loads cores for 100% and device continues running.
