I'm writing this because this is what i did (just to give my little experience). I have an udoo quad and we bought a seco A62 to use the industrial version in my company. The first point when you move from udoo to Sa62 is that you can't use the same os image to boot to the card (you can't use udoobuntu directly). The reason is that the kernel and uboot is different ! When you buy this card, you have an access to a ftp (i don't know if we can give the information to access it here ? --> udooteam) .In this ftp, you have the FS and you need to build kernel and uboot (they gives good tutorials for that). They already have a tutorial for yocto 1.7, but i didn't have any success to make it ! I build an image with ubuntu 11.10 and qt 5.4.1 what work find (with a seco tutorial) for the moment. It's very too bad, that seco don't give an image (to put on sd card) that we can use for the first test like udoobuntu, you need to build your own under ubuntu 12.04. It would be interesting, that you provide a little guide to adapt udoobuntu2 to Sa62 udooteam ? I hope, with Graugans , we can adapt yocto 2.0.1 (that we test for the moment for quad and neo with qt5.5.1 --> works very well, another big thanks to him !) to Sa62 ! If someone that have an udoo and would have more information, i can try to answer with pleasure !
