Hello,
As of my knowledge cutoff in September 2021, the latest OrangePi board available was the OrangePi 4, and Deepin 20.x was not listed as a compatible operating system for it. However, it's always a good idea to check the official OrangePi website or relevant forums for the most up-to-date information on compatibility and supported operating systems for the OrangePi 5 board.
I see that OrangePi lists Debian as a compatible OS. Can Deepin 20.x run on the latest OrangePi 5 board?
