Yes indeed, and that is a perfect way to shut down our baby. It's another way of pressing the power button. Thing is you need another 10 sec. of shutdown power (to cleanly shutdown). So I'm looking for the use case where somebody stupid (talking 'bout me) yanks the 5V and I still get a clean shutdown. We need external 'ups' power for that last 10 sec. of shutdown. Now I keep 5V always on. Till power company screws up. 64 million dollar question: how many times can power company screw up before bbb screws up? Question remains why I get a unclean shutdow with me (the stupid one) feeding 5v to otg usb with powerbar and getting clean shutdown when connected to regular pc. Call me stupid but the correct answer awaits tickets for the next frank zappa concert! thx, Michiel -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
