13 Updating firmware
13.1 Overview
The EU5C-SWD-SERCOS Gateway is shipped with its most recent
firmware already loaded. The version of the loaded firmware is stated on
the device type label.
The firmware can be easily updated via the Ethernet interface of the
Gateway. When you perform a firmware update, the old firmware file in the
gateway will automatically be overwritten. The project configuration and the
target configuration in the gateway remain untouched by the firmware
update.
Please note that updating firmware via Ethernet is only possible if the
gateway is connected to the SmartWire-DT network and if it has a valid
SmartWire-DT configuration (SWD LED of the gateway is showing steady
green light), otherwise the gateway will not activate its Ethernet interfaces
(PHYs).
Hazard of device damage by disruption of voltage supply during
firmware update!
Do not interrupt the voltage supply while updating the firmware of the
gateway. Power failure during a writing process in the file system can
cause severe malfunctioning of the device.
Note:
In case of a missing or defective firmware (which is indicated by a
green
POW
LED), the “regular” firmware update process described
in this chapter is not working. In this case, proceed as described in
chapter
Firmware recovery via HTTP

There are two possible ways of updating the firmware:
Updating firmware via web interface of gateway
The integrated web server of the gateway provides a function to update the
firmware of the gateway by HTTP via its Ethernet interface. All you need is
a PC with an ordinary web browser connected to the gateway via Ethernet.
By entering the IP address
192.168.0.1
(this is the default address of the
gateway) into the address bar of your browser, you can connect to the
gateway’s web interface from where you can navigate to firmware update
page of the gateway.
Step-by-step instructions for this can be found in section
