Hi, every one:
I installed Armbian Xenial desktop legacy kernel 3.10.y on my OPI win plus , it's good.
(At least, Bluetooth, WIFI and Ethernet are good).
But after i execute "apt upgrade",The bluetooth is fault.
So, I tried to freeze the kernel upgrades, and hold "armbian-firmware"package, then run "apt upgrade", All do not work.
However, when i insert a BT-dongle(USB), this dongle is functional.
So I think there is a bug in some package, please help me to solve.
