It's now running a headless version of Debian. Apparently a lot of chips have been sent out which did not boot at all, but with re-flashing it seems to be possible to navigate around the bad blocks issue on the NAND flash. I didn't look too deep into the re-flashing but it seemed to me quite a stable and re-doable action. So, basically it's looking at uboot, how the DTB would have to look like and then we would end up with a booting kernel and a few drivers missing, you seem to know more about that than I do.
