I'm thinking of getting https://www.beagleboard.org/boards/beagley-ai
I see there is this page for it
https://www.armbian.com/beagley-ai/
I also see references to it in the code: https://github.com/search?q=org%3Aarmbian+beagley&type=code
Are there any pre-built images available for it? Or would I have to build one?
