What about GeeXboX? Some i.MX 6 based boards are compatible with it, so I think it can't be so hard to port it to UDOO... Look at http://download.geexbox.org/snapshots/.
Yeah i think this would be great. Is somone in the staff can say if a official support of XBMC (or its distribution like OpenElec or GeexboX) is planed ? (and when ?) I hesitate with the SolidRun when i bought the Udoo, and now it's seems to me that i made the wrong choice. The hardware is great but i don't find any software solution to run smoothly XBMC, some of them are close to be OK but we still miss the good and stable version.
