I have a Raspberry Pi 2 running without a hitch off of this microusb power supply, but my Pine64 just won't boot. The image looked like it installed to the card just fine, but can't boot at all. Just get a red LED (tried all combinations of peripherals, including none at all).
What is the voltage and amperage of the power supply? How long is the cable? How did you confirm that the image burned correctly?
Charger is listed as 5V 2.4a (total). It has two ports, so I don't know if it's supplying 2.4a when only one is in use or not. Cable is approximately 3ft in length.
Not sure how I would verify that the operating system was written properly. When using the image writer, it looked like it completed without a problem.
Ah, it sounds like you may be using one of those 'intelligent' chargers that changes amperage provision based upon what it senses the device to be. If it doesn't sense it as requiring a specific amperage, the default is only to provide 500mA (USB 2.0 standard). I would try a different power supply.
Also possible that the resistance presented by your USB cable is too high. Trying a different cable might also be beneficial.
These two things you have probably already considered and maybe even have tried by now.
The third thing, verifying the OS burn: if you have a computer running Linux, you should be able to detect the various partitions on the card (I certainly could via Ubuntu). Windows, however, did not properly detect the OS, though it did show that a certain amount of the micro sd was in use, indicating that there was something on there.
You could also try reformatting the card again and then reinstalling the OS. Some formatting programs seem to be more effective at formatting than others. I used gparted on Ubuntu, but there is also SD Card Formatter for Windows you could use (https://www.sdcard.org/downloads/formatter_4/).
Reformat and reinstall. Some users doing test-installs early on claimed that sometimes the install didn't seem to take first time but worked second time, so you could try that.
So - different charger, different micro USB, reformat and reinstall OS. Try these things by a process of elimination.
