Hi ,

I am using AM335x (RTC only )+TPS65910A with a rechargable 3.0V battery.

I find anissue regarding the charging . When I enable the charging by set up the register bit ,actually always enabled after power on, the battery voltage is charged to 3.0V around and also  the RTC running ok if power keep running , but when I power off and power on again, I found the RTC seems losing power, its time has been reset to 2000 Jan 1. if I diable the the charging function after power on , then power off and power on again, the RTC  works ok, the time is kept ,not reset, Can you advice how to fix the issue?

Appreciate your reply!

Jason
