Pine A64+ won't boot?

[tllim]

Hm, well, that's something I hadn't thought of.  Is there a list of verified working micro SD cards?

There are two things to take care of when it's about SD cards:

a) an enormous amount of fake SD cards exists (less real capacity or simply fraud)

b) random I/O matters therefore don't only look at the 'speed class' but rely on real tests that measured also random I/O. Using the wrong card will result in the Pine64 behave sluggish or not

That's why we (Armbian team) recommend the following: https://github.com/igorpecovnik/lib/blob...re-sd-card

That's brilliant stuff. Thanks for posting.

I got 3 of those Sandisk Extreme U3s so I'm lucky enough having the 2nd best according to that test. 
I'll be buying a Samsung EVO+ at some point to try it as well.

I've tried two different micro SD cards, both of which aren't fake and perform as expected:
PNY U3 Turbo Performance 32GB Class 10 UHS-I
Transcend 32GB MicroSDHC Class10 UHS-1

I've also tried 3 different power supplies:
Oneplus One 2.0A
2.4A (can't remember the brand)
Amazon basics 2.1A

I've also tried 3 different USB cables which all work fine for charging my phone

Either the Pine64 is super picky about the devices it can work with, or I got a dead board.  I've of course contacted Pine64 but don't expect a reply any time soon.

Please advise how you judge by not boot up or dead board. If judge by no video output, please advise what type of  HDTV or monitor that you are using?
