I'm working on a PCB now to mate with some software to allow the user to press a button, which will send a long GPIO signal to the ARM system. A daemon process monitors that GPIO and does an orderly shutdown when it goes low. The daemon also sets another GPIO high as it begins to shutdown. When that line falls low again after the board powers down then the external power switch cuts the power completely. This was designed to plug into my own power distribution board for a robot.
Might be not-to-difficult to make up a carrier board for that PCB that just feeds the BBB (or a RaspPi) with a barrel connector and a two-pin cable. If the prototypes function right I could send you one. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
