weird, this is likely either flakey DC Jack connection, or PMIC going bonkers. How do you guys reproduce this ? Is the board idle or is it running ? Which gadget driver ? Is USB cable connected to a host ? A desktop host or wired back into the host port of BBB itself ? I wanna try to reproduce it here. -- balbi -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
