Hello, I have installed Ubuntu 20.04 in my bpi-r2 , I have a problem, if I restart or shutdown my board, I ping my bpi-r2 and the ping never stop, ping still active, I need restart with the reset switch on board.
Best way is always install a fresh system instead of upgrading,but you can try upgrading my 18.4 which also has a newer kernel. As i tried official images i noticed some bugs while running (don’t remember if it was debian or ubuntu) so i created clean minimal images for debian stretch/buster/bullseye and ubuntu 18.04…not created a 20.4,but wrote steps down in my wiki…
Basicly bootstrap an ubuntu 20.04,backup /lib/modules from image, delete all from root partition (do not touch bpi-boot),copy bpotstrapped rootf and copy back /lib modules. Then proceed with steps i’ve wrote down in wiki. At least change root-pw and add apt sources.
It’s ok,so issue solved? I guess armbian kernel does not support r2 internal wifi,but if you don’t need it you can use it. Maybe you can replace kernel with mine to have the mt6625 driver
