   How to update WebControl 8 firmware

The older WebControl firmware must send to factory office for getting firmware update. Since 3.02.17d firmware, we implemented a bootloader feature allowing user to update firmware in its own locaiton without shipping the board in. There are two ways to identify if your board has bootloader support or not. First, if you simply power off your board and power back on, if the amber LED on the network socket blinking 3 to 5 times before change to steady on, your board has bootloader. Another way is to check the build-date on your firmware. If that has build data July 26, 2013 or later, you have a bootloader enabled firmware.

This document describe how to update firmware with bootloader enabled firmware. If your board has older firmware, please contact us directly to send your board in for updating your firmware. Any HW rev 2.2.2 board will be updated to latest firmware with bootloader support during update.

Firmware update should be done on a wired network, DO NOT ever perform update over WIFI network, best directly connected to the computer over cross over cable, since WIFI can suddenly reset the connection when any WIFI connected device sending request to the WIFI router, that will terminate the firmware update in the middle. Any unreliable network, package loss, or power loss during updating could result board not operational.
