Date and time problem

Hi, I have a problem with the date and time update on Xavier NX.
After the board is turned off for more than a day, it won’t update the date and time after booting.

How to make the date and time automatic update after booting without internet?

Many thanks.

Did you have connect coin battery to NX board?

Not yet, I use Xavier NX developer kit.
Which part is the baterry slot?

Oh, I found the battery slot.
Do we need the 40V/3A Schottky Diode?

Sure, it is necessary otherwise the battery is not connected to module connector pin.

ok, thanks

Hi, for Xavier NX it doesn’t need diode, it already has diode on D4.
I’ve tried it without additional diode and the RTC works.

Hi, I soldered on a Xavier NX a CR1220 battery with its holder but the date and time is not restored after reboot.

Do I need to modify something on the software ?

Please let me know
