    Graugans, just tested your image and all work fine with lvds7 ...
    I did this :
    download the image
    copy it to the sd : $ zcat udoo-image-qt5-udooneo.sdcard.gz | sudo dd of=/dev/sdd bs=32M
    open uEnv.txt in kate and modify the video_output=hdmi to lvds7 (don't forget to erase # !)
    boot the card ok :D

    I am planning to write a tool for managing this uEnv.txt stuff. The PHP5 is a bit too heavy for a BSP layer. So I'll go with C++ or ruby (due to the fact ruby is on master now :))

    CAN is in the external pin, and thus has been disabled on mqx/Arduino. In order to make it work you have to fix mqx by hand.

    It looks like the default m4 firmware occupied those PINs on arduino. Thus CAN can not be used. By uploading a custom m4 firmware everything works fine. This also applies to UDOObuntu
