Hello guys with same interests on this Nanopi M4 SBC. I got one around a month ago, and tested all the OS they uploaded to Google drive in Sep. Lubuntu has problem on bluetooth, Bionic has problem on sound and video. 3rd party ROM also doesn't work well. For starting guy with embedded Linux like me, it's really painful to debug. many GB source codes to download if you wish to compile from the very beginning and spend hours setting up environment. While I don't have that much time to learn and act. So I just contacted their engineer for the bugs. They told to fix in later ROM's. I checked daily. Just now found they uploaded something new to Baidu netdisk https://pan.baidu.com/s/1rZmMQEQL1tu15R6IeYrksw#list/path=%2FFriendlyELEC-RK3399 on 11/7. I'm trying to download one and test. Stingy Baidu, they limit the download bandwidth if you didn't subscribe their golden medal membership. Guys out of China may wait for vendor to upload to Google. Google doesn't constraint your downloading. I love Google.
