Hello, I am trying to setup the RTC with a CR1225 battery following the instructions in the forum (just soldering the bracket and inserting the cell coin), but the RTC resets every time I power off the board. I checked the voltage between the (+) in the battery and GND in the board and it is 3.3V,…

Coin cell is connected to PMIC_BBAT of PMIC, PMIC_BBAT is bidirectional. It will supply power to external when nano board have DC_IN supplied. The diode prevent current supply to Coin cell. The diode is needed on the design.

The diode or shorting connection is necessary… It was assumed to be there, so the problem is the coin cell is not connected to RTC as no diode or shorting?
