I run OctoPrint on a RockPi, but I also rolled my own embedded Linux distro (PrintNanny OS) to package this setup.

There are a lot of small papercuts, like OctoPrint using `vcgencmd` to measure CPU throttling. `vcgencmd` is part of Raspberry Pi's userland. Not a big deal (aliased to another util). I've also added WebRTC-based streaming to my build.

The recommended way to use OctoPrint is the OctoPi image, which is based on Raspbian / Raspberry Pi OS. The OctoPi image includes extras like haproxy and mjpg streamer for HTTP-based JPEG frame stream. If you end up baking a RockPi image, here's the OctoPi root file system for reference: https://github.com/guysoft/OctoPi/tree/devel/src/modules/oct...
