Unfortunately I need support for a newer kernel than the one that Phytec supports (3.12). Mainline kernel 4.4 is supposed to work ”out of the box” on this module, but I have a problem booting the machine: > > I use Barebox as bootloader and it works up until the point where the kernel is loaded.

I have the 4.4 kernel configured as close as possible to the known working config of 3.12, and if I exchange the 4.4 image with 3.12 it works as expected. > > I’m running out of ideas and since there is no console output at all I don’t know how to debug this any further… Any hints?
