The U-boot menu will automatically appear at startup, and then select
the required options through UP/DOWN Key.
NAND Flash and eMMC Flash instructions:
1. Set your computers IP adress to 192.168.1.2.
2. Run a TFTP server providing the sysupgrade.bin image.
3. Power on the router, into the U-Boot menu.
4. Select "2. Upgrade firmware"
5. Update sysupgrade.bin file name, input server IP and input device
IP (if they deviate from the defaults)
6. Wait for automatic startup after burning
