serial communication to the board by pressing the Call button.
4. Press and release pushbutton S3, /POR. The board will reboot and eventually display

Note:
The initial error about configuration checksum error is expected for a brand new board or a board where the Flash device
has been completely erased. This happens because the Flash memory has not been initialized for redboot yet.
Note:
Linux is case sensitive, pay close attention to the commands that follow.
Note:
Steps 5-9 are for new boards only or when putting Linux on the board for the first time or for boards where the Flash device
has been completely erased. If you have already configured the board, proceed to step 10.
5. Initialize Flash memory by typing "fis init -f" at the RedBoot> prompt.
