I just flashed Debian Stretch Minimal via PINE64 Installer onto my SAMSUNG EVO 16GB MicroSD Card and plugged to my 2GB ROCK64, boot it up and wait for the boot messages running through my monitor and finally reached login prompt. So, no problem with my setup.
Note that, I don't have eMMC, I just connect power cable, HDMI cable and network cable. I tried boot with jumper on the 2 pins near the power button and also boot without the jumper, both also no problem.
You can probably try flashing other OS or try another MicroSD Card.
