Ubuntu 14.04 installation instructions for x-gene Mustang reference board (ARM64)

Before You Begin

You will need the following:

  1. An Applied Micro Mustang reference board (get yours here!)

  2. A management device for console access
  3. DHCP available which will provide Internet access (to access the Ubuntu package archive)
  4. A TFTP Server accessible from the system

Download netboot images

Download netboot images from X-gene netboot images and place them in a directory on your tftp server. Subsequent instructions assume you have placed these files in the directory xgene in your tftp server root. Please modify as required if you chose a different path.

Hardware Requirements

Requires a board with A3 silicon, running firmware based on the APM's 1.13.28 release.

Currently only 1 of the 4 ethernet ports is supported (the one over the USB ports), and only at Gig and 10Gig speeds link rates (10/100 is known not to work). These limitations will be removed overtime.
