An update: For the A6 (Beaglebone Black) version, I connected U4 pin 1 (enable) back to VDD_3V3AUX (same as A5C). It now shuts down correctly while on battery. This was verified on two A6 BBB.
The mystery is what causes the VDD_3V3A to hang up on the A6 version when shutting down while on battery. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
