A bit of crude hackery has it booting most of the way through device setup, but then it hangs. Also, no devices work yet that could host the rootfs. The ethernet never sees a link-up, usb never probes the busses sucessfully, and something hangs before mmc/sd even gets a chance to do its bus probing. Still, I made some progress compared to my 15-minute attempt a few days ago where I couldn't even seem to get the kernel to start (turns out it was kinda starting, but the hobbitboard puts the serial debug console on uart6 so I didn't see it). -- Ian
