I'm not saying what you want is not possible, I'm honestly not sure if this is possible on this platform or not. More or less like it's possible and most if not all X86 style systems. What I am saying is that if you rely solely on the beaglebone, you're asking for trouble. For several reasons, but for starters, there is no functional watchdog hardware module on the beaglebone. Passed that, if the processor on the beaglebone has to be active, but even in low power mode. The PMIC has to be active as well. Comparatively, this will use a lot of power. Compared to something that was specifically designed to use micro, or nano amps. Those are just two reasons. There are many more reasons if you think about it hard. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
