1. Place openwrt-ramips-mt76x8-skw92a-squashfs-sysupgrade.bin on a TFTP server
2. Connect to serial console at USB3 on EVB (57600 8N1)
3. Connect ethernet between port 1 (not WAN) an your TFTP server (e.g.
   192.168.11.20)
4. Start terminal software (e.g. screen /dev/ttyUSB0 57600) on PC
5. Apply power to EVB
6. Interrupt u-boot with keypress of "2"
7. At u-boot prompts:
   Warning!! Erase Linux in Flash then burn new one. Are you sure?(Y/N) Y
   Input device IP (10.10.10.123) ==:192.168.11.21
   Input server IP (10.10.10.3) ==:192.168.11.20
   Input Linux Kernel filename (root_uImage) ==:openwrt-ramips-mt76x8-skw92a-squashfs-sysupgrade.bin
8. When transfer is complete or as OpenWrt begins booting, move ethernet to
   port 0 (WAN).
