This step will set up minicom (serial communication application) for

SDK development

For boards that contain a USB-to-Serial converter on the board such as:

    * BeagleBone

    * Beaglebone Black

    * AM335x EVM-SK

the port used for minicom will be automatically detected. By default Ubuntu

will not recognize this device. Setup will add a udev rule to

/etc/udev/ so that from now on it will be recognized as soon as the board is

plugged in.

For other boards, the serial will defualt to /dev/ttyS0. Please update based

on your setup.
