Setting up the RTC on an ODROID C2 running Arch Linux

Published 2016-12-08

The Hardkernel wiki page for the ODROID C2 RTC shield is mostly specific to Ubuntu and Android. Here’s a quick update if you’re using Arch Linux ARM. Install community/dtc to get fdtput. sudo pacman -S dtc Enable the RTC shield in the device tree. NOTE that this should all be on one line as one command. sudo fdtput -t s /boot/dtbs/meson64_odroidc2.dtb \ /i2c@c1108500/pcf8563@51 status "okay" Load the Amlogic i2c kernel module.
