There is a signal, on P9 I believe, called “power”. If you pull this pin low with a pushbutton switch, you will get the clean shutdown you are looking for.

I like this behaviour and thought I could use it to cleanly shutdown the bbb. I therefore connected a 'powerbar' usb battery to the usb otg port. Now when I remove the 5V (strangely called ac) I expect a clean shutdown on power delivered by my cheap 'ups'. Only I find out that in /this/ case the bbb shutdown immediate instead of a clean shutdown! So there seams to be a difference in connecting the otg usb to a pc or just to a powerbar. Anyone who can explain this behaviour? In my quest to shutdown a bbb simple, cheap and clean. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
