Kerry,
I seem to have the same problem than Manohj. Beaglebone board is plugged in computer, blue light in Pocket NC flashes but that's about it, in my mind it is getting electricity but there isn't any red light flashing.
I have to add that we have used the machine, that actually I am in the middle of a project and I was changing the head when the problem happened. We are using the machine with a Chromebook. I tried to look for updates to the drive but I have not been successful, the wheel keeps spinning when I tell the "website" to look for the updates.
If you could help me to solve the problem, I would appreciate it. Thank you!
