However, with that said, the documentation I've seen to date is not what I'd consider to be complete.

About the only thing I can think of is that you could hook up a 3v3 logic USB to UART module / cable to see if uboot gives you any additional information as to what's happening. I'd probably contact the reseller you purchased this from however, and look into getting an RMA. Because if everything is as you say( no left out details ), it sounds like a potentially defective board. Which I've yet to see a defective beaglebone black, or green to date, and I've handled quite a few greens( 50 +). I'm considering buying one myself just so I can help others troubleshoot the board once in a while. But that may / may not happen. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
