    I will be using the Udoo in a few different prototypes. For some I need a Quad, but for others I only need a dual. I am going to maintain a single image for all the Udoos. Is it possible for my Quad Ubuntu image to work on a Dual? If so, how would I do this?

    Thanks

    You'll probably need to change the "Device Tree blob" file corresponding to to Quad or the Dual loaded by U-boot, depending on which one you're using. (I don't know if you can use theses things with kernel 3.0.35, but it's how it seems to work now with 3.10.17). Except that, it should work with the same rootfs and kernel without any problem I guess.

    The following dts files are from jas-mx's 3.10.17beta kernel (here). Thanks to him !

    Here's the dts file I slightly modified for the dual (I'm currently using this one):
    Udoo Dual DTS
    And for the Quad, from jas-mx's git repo:
    Udoo Quad DTS
