- Do not use a DVI-HDMI adapter. If you want video output, use a HDMI cable direct to a HDMI monitor or TV. This may change as development continues.
- Get a USB power supply that is at least 5V/1.5A. An underpowered supply will not boot the board.
This paragraph describes a successful connection providing a UART Serial Console on a Linux Host. The PINE64 board used is a 2GB version (A64-DB-2B-Rev 6). The connection is provided by a FTDI TTL-232R-RPi 3-wire cable purchased from Digikey:
The successful connection is made on the EXP connector:
- Connect the Black GND wire to Pin 6 or 9 of the EXP connector.
- Connect the Yellow RX wire to Pin 7 of the EXP connector.
- Connect the Orange TX wire to Pin 8 of the EXP connector.
Plug the FTDI TTL-232R-RPi USB end into your Linux host. Find the tty that has been assigned to the FTDI TTL-232R-RPi by opening a terminal window and typing $dmesg. The last group of messages will show you how Linux has mapped the FTDI TTL-232R-RPi to the tty. In my case the output appears as:
[308564.376087] usb 3-1.1: new full-speed USB device number 10 using ehci-pci [308564.474534] usb 3-1.1: New USB device found, idVendor=0403, idProduct=6001 [308564.474541] usb 3-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [308564.474545] usb 3-1.1: Product: TTL232R-3V3 [308564.474548] usb 3-1.1: Manufacturer: FTDI [308564.474551] usb 3-1.1: SerialNumber: FT99JN2P [308564.476846] ftdi_sio 3-1.1:1.0: FTDI USB Serial Device converter detected [308564.476906] usb 3-1.1: Detected FT232RL [308564.477263] usb 3-1.1: FTDI USB Serial Device converter now attached to ttyUSB0
The final line of the output indicates the FTDI USB Serial Device has been assigned to ttyUSB0. Now open a screen session with:
$sudo screeen /dev/ttyUSB0 115200
Boot the PINE64 and you should see output in the terminal window on your Linux host.
