1. Load Ramdisk via U-Boot

To set up the flash memory environment, do the following:
a. As a preliminary step, ensure that the board console port is connected to the PC using these RS232 parameters:
   * 115200bps
   * 8N1
b. Confirm that the PC is connected to the board using one of the Ethernet ports.
c. Set a static ip 192.168.99.8 for Ethernet that connects to board.
d. The PC must have a TFTP server launched and listening on the interface to which the board is connected.
e. At this stage power up the board and, after a few seconds, press 4 and then any key during the countdown.

U-BOOT> set serverip 192.168.99.9 && tftpboot 0x84000000 192.168.99.8:openwrt.itb && bootm
