Hardware issues with Rock64
#11
I don't usually use "Armbian" so I'm not familiar with this distribution.
But, you referred to "Armbian" as a concrete example.
So I decided to list the results I confirmed about "Armbian" that below.
The result is as follows.

Armbian: 2020-09-03 -> Now version
Code:
