Some hifive boards appear to work after reflashing with new procedure, others don't, investigating.

I've determined that this is indeed a crostini problem, likely caused by the latest update to the cros dev channel that had other exciting breakage as well. For the time being, if you're using a chromebook use a chroot; termina /dev/ttyUSB0/1 connectivity is ... a bit of a mess.
