Hi eveybody, Recently I have received a beagleboard-XM. I experienced exactly the same problem. it was running without problem. once I wanted to insert audio jack, I touched SD card, then I tried to restart the board then it never boot again!! Same signs, D5 remains green, D13 blinkd red when I plug the power supply. D14 just turn on (Green) and then off.
Have any of you found a solution? Thanks in advance On Friday, February 25, 2011 at 6:11:13 PM UTC+1, Jacek Radzikowski wrote: > > Recent versions of xm don't have flash memory on board.
