[Odroid C2] RTC

Can the c2 RTC be used with armbian?

I bought one of these RTC shields when I bought my C2. It seems to work as expected, i.e. I can set or read it with hwclock, /dev/rtc exists, etc.

 

You do need to follow the instructions on the hardkernel wiki, though:

Basically, you enable it in /boot/dtb/meson64_odroidc2.dtb, add the aml_i2c module to /etc/modules, and add "hwclock -s" to /etc/rc.local

 

N.B., having just upgraded to 5.20, I needed to reenable it in the updated dtb file.
