Needs more investigation. > Anyone else having problem booting on beagleboard xM? Seems something > wrong happened after 1.1 release... We are working on several bugs on our reference beagleboard. The problem is that my beagleboard died (a horrible painful death) and the other boards that are directly available to are RevC and they are booting. So things are slowed down a bit .. but we are trying to get to the bottom of it, as fast as possible.
