How to use RTC on Orbitty Board


I’m using jetson tx2 module with Orbitty carrier board.
I connected CR2032 battery like the attached image,
but jetson module does not hold time.
Do I need to do anything else?

Thank you

Please ask Orbitty for this directly.


The RTC battery maintains the hardware clock which is separate from the system clock displayed in Ubuntu.
Hardware clock: hwclock --show
System clock: date

The hardware clock can be set manually
sudo hwclock --set --date=“2017-10-24 20:49:00”

The system clock can be synchronized to the hwclock with the following command.
sudo hwclock –s
