We’ve been working on a couple generic SBC images. These images should be considered “beta”. They can currently be found here. There are some notes in the readme. Boards currently being tested include several from Libretech (tritium, la frite, potato, renegade and renegade elite) as well as a few rockchip-based boards such as the orange pi 5 and rock 5b.
Please share feedback via the “sig/altarch” channel on mattermost.
