Hello,
After serveral tries, I cannot make the ubuntu 12 distro booting on my igepv2.
The tutorial http://labs.isee.biz/index.php/IGEPv2_Ubuntu_Distro to use ubuntu on sd card is working fine but I cannot transfer the image to flash (ubi) despite the clear isntructions from this tutorial http://labs.isee.biz/index.php/IGEPv2_Ubuntu_Distro_flash.
(I am using the armel version of ubuntu 12).
Here is the output from the serial console:

It seems that it cannot fing the rootfs...

Maybe I am missing something silly but after several attempts, I don't know what to do next...
So if you have some ideas, I would be grateful.

I guess you should change the igep.ini file root variable from:

root=ubi0:igep0020-rootfs

to

root=ubi0:rootfs

    Thank you for your advice Manel, I can move a little step forward, but I got stuck again. Is it ok to have 0KiB for root?

    Ok, I can now boot ubuntu from flash!
    In fact, I had to keep the original /etc/fstab file to boot :
    /etc/fstab:
    LABEL="boot" /boot vfat defaults 0 0


    After first boot, I installed the linux image and wifi packages and reboot. Everything is now working! (However the fstab file is now empty, not sure why, maybe somebody has an answer...)
    Thank you for your help!
