What are you trying to boot?

I kept the rootfs line to boot from internal flash, but, with fanoush's initfs, you can still choose which to boot from.

If you go into device drivers->watchdogs there should be an option "Disable watchdog shutdown on close" - you don't want that. Without it, you can at least see what's messing up your boot.

I've also set up a n810-dedicated thread here:

in an effort to make stuff easier to find and more consolidated.
