Hi,
Just for anyone interested, I bought an FTDI Chip TTL-232RG-VREG1V8-WE (1.8 volt) USB to TTL serial cable and soldered the wire leads the the Hikey J16 as so:
ftdi orange (TX) - Hikey pin2 (RX) ftdi yellow (RX) - Hikey pin4 (TX) ftdi black (GND) - Hikey pin3 (GND) ftdi red (VCC) - open ftdi green (RTS) - open ftdi brown (CTS) - open
Seems to be working fine.

Working fine here too. I have the variable voltage version (TTL-232RG-VIP-WE) which requires the red lead to be connected to the HiKey pin 1 (1.8V).
Let me add that I use miniterm.py to connect: miniterm.py --lf /dev/ttyUSB0 115200 Install with 'sudo apt-get install python-serial' if you're using Ubuntu. Very simple and works perfectly.
Cheers,
