I have a Li-Ion battery connected to BBB (A6) to supply backup power in case of 5V power failure. If starting with 5V connected and I remove 5V the board continues to run as expected with no issues. If I then re-apply 5V power to power connector after a short while the BBB shuts down. I assume it’s in the OFF mode as pressing the POWER button will cause board to wake up.
If I start with just battery power and no 5V connected by pressing the POWER button to start (wake up) board then the board runs fine until I apply 5V power which again causes board to shutdown.
Has anyone experienced this or have any suggestions?
Thanks,
Colin
