You can use a LiPO battery, connected to the PMIC battery test points( ask an EE if you need specifics ), then install the debian package acpid. Then everything should be fine. e.g. the board will power down cleanly. However, the PMIC will still be supplying a bit of power from the battery. So if you need it shutdown for an extended time period. You'll need to disconnect the battery. As for remotely installed systems. You'll have to design a watchdog / power management system to disconnect the battery, and reset the processor when power is reapplied. This is why in Jason's post yesterday, or the day before. I mentioned I like to see a proper UPS cape with good power management features built in. The beaglebone as it is is what I'd consider a very good board, but to cut costs, when designed. Several things were left out of the board. So instead of paying $100 + per board, we pay ~$50 per board, and design in features we need for our own situations. A fair trade, but something we need to be aware of. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
