Step by step setup and startup guide
General Notes
The procedure described in the following pages shows how to add the Ubuntu System to
the SD card. The SD card is the boot device for Babbage 2.5 board. The procedure shown
is made entirely using an Ubuntu host; this implies that the commands are specific to this
distribution.
The sections in grey indicate the commands that need to be executed in each step using
the Linux host. Most of the commands executed, require a supervisor level, so most of
the cases use the sudo before each command. The sections in blue indicate the commands
needed to be executed in the terminal when Ubuntu is launched in the Babbage board.
