Create the Boot Image

  1. Obtain a high quality microSD card.  A Class-10 card of 16GB or more is recommended.
  2. Follow the latest instruction for installing an image from the Raspberry Pi download site.

Boot for the First Time

  1. Place the microSD card in the Raspberry Pi.
  2. Attach a monitor and keyboard/mouse to the Raspberry Pi
  3. Attach Ethernet via the RJ-45 jack to your network.
  4. Apply power via the microUSB port next to the HDMI port 
  5. Allow the Raspberry Pi to boot up
  6. Login  (User: pi, Password: raspberry)
  7. Perform any Linux configuration specific to your installation, e.g. assign specific network addresses, install favorite tools, etc. (This is beyond the scope of NW Digital Radio support, please use Linux support resources for assistance.)
    Note: DO NOT RUN raspi-update - it will break your install
  8. You may wish to edit the /etc/hosts file and add a reference to the hostname, for example if you keep the default 'compass' hostname, add a line compass
    If you want to change the computer hostname use the command:
    sudo raspi-config
    Then select "Advanced Options" -> "Hostname" and follow the instructions.  It will update the hostname for your Raspberry Pi and will make the change in /etc/hosts
  9. Insert the ThumbDV™ and observe that it appears at /dev/ttyUSB0
    ls /dev/ttyU* will list all USB serial ports, if you have a GPS, another ThumbDV™, or other serial device they may also be listed. Be sure to locate the one with the newly installed ThumbDV™.
  10. To gracefully shutdown the Raspberry Pi, you may use the command:
    sudo halt

Install AMBEserver

Use the on ambeserver-install from Github.

Reboot your system.  AMBEserver should be running and listening on UDP port 2460.
