I just wanted to report that F22 works very well on the PcDuino3 Nano. In fact, I installed the LXDE image, and this is the first time I've seen the graphical startup screen.
There are a few things to note.
1 - The graphics were at the lowest res and couldn't get any higher. (Was expecting this)
2 - I haven't tested the SATA yet (need to get the cables)
