Hi. I bought some time ago a OPi One and a OPi PC. Yesterday i tried to setup them with armbian without success until I switched images from one to another and...it worked. I think that the download page for each should be fixed ( 5.4.20 image ). Made me crazy as a beginner until I figured out, tried different micro sd cards, different power supplies... Sorry for my english. Many thanks for developers who makes something stable for this boards.
