TPS65217 and Battery question


Have a BBB with a LiPo battery attached as per all relevant instructions. Appears to be working fine with the exception of when the main DC supply is disconnected; The Prompt to Shut Down/Restart/Discard flashes on/off rapidly and since I am then on LiPo power not user input can be made. It defaults to shutting down in 40 seconds.

I am ultimately trying to use the battery port as a “UPS” of sorts to allow the unit to weather temporary power dropouts (Industrial environment where I suspect this will happen often) without any user input. I have read the 65217 data sheet but nothing jumps out at me (surely I am looking right at the answer, but I don’t “see” it). Any suggestions?
