Oh, and right. If you have a serial debug cable plugged in. Remove it from the remote end while the board boots. I've personally run into a no boot situation when the serial debug cable is plugged in. I can not tell you how that happens, but I can tell you what I was doing when that happened. Basically I was attempting to get output from the serial port on the remote end formated properly, and I was using cat to dump the text e.g. cat /dev/ttyUSB0. However it will not happen most of the time, which is why it's hard to track down *how*.
