@062621AM Hello, I have been an Ob3pi user for a few months. The problem that I have seen is that there are 3 types of models v1, v1.1.1, v2.1, it is in the latter where the Wi-Fi and Bluetooth chip changes and also the size of the NVME (2280). For these changes to work correctly in the official distribution, they add a dts (orangepi3b-v2.1.dts). The latter is not integrated into any old distribution, since the manufacturer just distributed this board a few months ago. If you use the hardware as a server, you may not notice errors in the GPU, VPU, BLUETOOH or WIFI. Until the moment I write this comment, the only distro that I have been able to use is the Ubuntu - Rockchip project. But even this has problems with the hardware already mentioned.
