Is umbrelOS compatible with Buffalo NAS devices, such as the LS220?
If you mean installing umbrelOS directly on the LS220, that model isn’t supported. It has an older ARM processor and only 256 MB of RAM. The NAS/PC download is for 64-bit Intel or AMD hardware, and the Raspberry Pi image won’t work on the Buffalo.
You could still keep the Buffalo as a NAS and run umbrelOS on a separate mini PC or Raspberry Pi 5, then access its shared folders over the network through Umbrel’s Files app.
