I managed to bring my Beagleboard to a complete halt. For no good
reason, that I can recall, I reset the board at the prompt immediately
after erasing NAND as shown below. I've attempted to reboot from the
SD and USB per "http://elinux.org/BeagleBoardRecovery". Only the LED
closest to the audio input comes on. I am holding down the user
button prior to connecting the the USB cable to the PC. Any
suggestions? Thanks.
