Flash instruction (using U-Boot CLI and tftp server):

 - Configure PC with static IP 192.168.1.10 and tftp server.
 - Rename "sysupgrade" filename to "firmware.bin" and place it in tftp
   server directory.
 - Connect PC with one of RJ45 ports, power up the board and press
   "enter" key to access U-Boot CLI.
 - Use the following command to update the device to OpenWrt: "run lfw".

Flash instruction (using U-Boot web-based recovery):

 - Configure PC with static IP 192.168.1.xxx(2-254)/24.
 - Connect PC with one of RJ45 ports, press the reset button, power up
   the board and keep button pressed for around 6-7 seconds, until LEDs
   start flashing.
 - Open your browser and enter 192.168.1.1, select "sysupgrade" image
   and click the upgrade button.
