Raspberry Pi Imager Writing Roxora with Imager

Repository file

Raspberry Pi Imager can list operating systems from a repository other than its default one. Roxora publishes one, rebuilt from the releases every time this site is built:

https://roxora-os.github.io/os_list.json

It lists the newest image for each board. Imager downloads the image from the release on GitHub and checks it against the checksum in the file before it writes anything.

In the app

Open Imager 2 and choose App Options.
Next to Content Repository, choose Edit.
Select Use custom URL, enter the address above, and choose Apply & Restart.
At the device step, choose your board. Then choose the Roxora image and the card or drive to write to.

To go back to the default list, open the same dialog and select Raspberry Pi (default).

From the command line

Start Imager with the repository given as an option. It applies to that run only.

rpi-imager --repo https://roxora-os.github.io/os_list.json

What to expect

Roxora images are for the boards on the Boards page (Radxa ROCK 4D, ArmSoM CM5-IO and RK3576 boards with UEFI firmware). They do not boot on a Raspberry Pi.

Devices: The device list shows the boards Roxora supports, and each board shows only its own images.
Radxa ROCK 4D: The ROCK 4D does not boot from an SD card until U-Boot is in its SPI flash. See Boards and the Radxa ROCK 4D documentation.
First login: User roxora, password roxora, on the console or over SSH. You are asked to choose a new password straight away. Imager’s OS customisation is not offered for Roxora images.
Other tools: Imager is optional. The Download page has every image file, and any tool that writes compressed raw images works.
