Flash instruction through LuCI:

This device is flashed OpenWRT base firmware with this target.
The LuCI webpage is integrated in default for upgrading.

Flash instruction through u-boot:

1. Prepare the TFTP server on PC.
2. Connect uart to PC, select "2. Upgrade firmware" in u-boot menu.
3. Select "0 - TFTP client (Default)", input client IP, server IP, flashed bin file path
4. Wait about 60 seconds to complete flashing
