Mark, Have you considered using an external embedded MCU for this task ? e.g. . . .
Board boots, does its thing, notifies and external MCU it's about to shutdown, then shuts down. The MCU then breaks the connection from battery to beaglebone, reconnects after 5 minutes, and toggles RESETn. As for which MCU ? That up to you, but there are MCU's that can run off a single button cell for 10 + years . . . On Mon, Jul 25, 2016 at 11:09 AM, Mark A.
