Software support

For ROCK 3A

Upgrade kernel to at least version 4.19.193-35-rockchip

You can uncomment line like "deb http://apt.radxa.com/buster-testing/ buster main" in file /etc/apt/sources.list.d/apt-radxa-com.list to add testing source.

See file /etc/apt/sources.list.d/apt-radxa-com.list

deb http://apt.radxa.com/buster-stable/ buster main

After adding testing source, you need to update APT and install your needed packages.

$ sudo apt-get update
sudo apt install -y linux-4.19-rock-3-latest

Add the item "radxa-5inch-touchscreen-on-rock-3a" to line "overlays=" in /boot/uEnv.txt
