Flash instruction:
Using UART:
1. Configure PC with a static IP address and setup an TFTP server.
2. Put rootfs into the tftp directory.
3. Connect the UART line as described on the PCB.
4. Power up the device and press Ctrl+C to break auto boot.
5. Use `system 6` command and follow the instruction to set device
and tftp server IP address and input the rootfs file name.
U-boot will then load the rootfs and write it into
the flash.
6. Use `system 1` command and follow the instruction to set device
and tftp server IP address and input the firmware file name.
U-boot will then load the firmware once.
7. Login to LuCI and use LuCI upgrade firmware.
