Hello @sbender, first of all welcome to the balena community!
How do you trying booting? Are you using an SD card? If so, have you verified that SD card is flashed fine?
As far as I understand, Beaglebone Black has a rather different booting method. I saw other users having boot issues as well and they resolved it by making sure that their board boots from the SD card for the first time:
Could you please check this and make sure you follow the recommended steps?
