I had problems with setting up an official image that I could not solve even with the support of the Radxa team.

I found unofficial Ubuntu images for Rockchip RK35XX chips, which I managed to get running. Here I describe a small guide on how I managed to do it. The biggest challenge is that I run Radxa Zero 3W in headless mode and connect only via SSH. To do this, you need to configure WiFi before the initial boot (or even after the initial boot).

(here are ArchLinux images for Rockchips)

To configure WiFi on the SBC without the ability to interact with the operating system itself, I configured the file /etc/netplan/50-cloud-init.yaml where I set the parameters of my WiFi network. Then I start SBC and monitor my network, waiting for a new device to connect. Having found the connected device, I connect to it via SSH using the default user for Ubuntu - ubuntu with the password - ubuntu.

In the end, I have a working Ubuntu on Radxa Zero 3W
