Problem Installing Linux on Rock64

[Rockfan]

if I was you I would test out the following:

* Try a different power supply, especially if the one you are using is below a 3A rating.

* See if you can get a slower SD card to try. It seems to me that (at least with mainline) the Rock64 may have some trouble with some cards. Like I have some Samsung EVO cards that seem to have problems with the Rock64 but slower Patriot Class 10 ones work OK.

Well I'm using the official power supply adapter which was supplied with the Rock64 so that shouldn't be an issue. 

Ive tried three different cards so far. I dont have a slower card than class 10, but the cards I have are all 2-3 years old, one of them brand new.
