Also, I have a 3.5A uUSB wall wart that I bought for my Pi2 (I got tired of seeing the rainbow cube while watching videos in kodi)
If the latter successfully prevented that RPi symptom then please give this PSU a try first (since then it's NOT a smart charger but provides the amount of amperage to Pine64 that is needed and not maxes out at 500mA).
Regarding Euler bus. When I made the picture above I simply got so sick of Micro USB related power problems that I used 4 cables. 2 are enough (5V to pin 4, GND to pin 6). And according to TL Lim and schematic the Micro USB based DC-IN and these Euler pins are connected directly (so when you power your Pine through the Euler pins you could also use the Micro USB barrel to charge phones and the like
) I would give the 3.5A PSU a try first (Pine64 won't exceed 1A with normal 'workloads' but the real problem are voltage drops mostly caused by USB cables with insufficient gauge ratings -- never try anything above AWG 20)
