I just connected to the Pine A64+ with a Raspberry Pi A+
Pi GPIO-Pin6 --> Pine EXP Pin9
Pi GPIO-pin8 --> Pine EXP Pin8
Pi GPIO-Pin10 --> Pine EXP Pin7
on the Pi, using minicom
dev serial device: /dev/ttyAMA0
Bps/par/Bits: 115200 8N1
Hardware flow control: N
Software flow control: Y
if you see:
HELLO! BOOT0 is
then you're in
if you're already connected when you power on the Pine, you'll see the boot messages before it drops to a shell
