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?
Hello,
Searching around the net and on NVIDIA forums I see some people claim they had success with adding RTC battery to Nano. Here is what I just tried a couple of hours ago. I have Development board B revision.
After soldering RTC battery holder and inserting non rechargable CR1220 battery (I ordered several CR1225 online I will use these when I get them), I booted with the latest L4T created with the SDK manager. Nano is connected to the network so system time is synced automatically soon …

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.

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
