I've seen similar behaviour on a subset of my BBB-s and BeagleCores - perhaps 1-3 out of ten just refused to shut down when powered via 5V supply input. Hasn't bothered me enough to dig in, but since it's specific to a few hardware specimens, it doesn't look like a software issue. -- Kind regards, Tarmo -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
