Software update

As of software release 2.1.0 the system automaticly checks for updates when the host computer is connected to internet. If you have the latest release you will see a green checkmark as shown below. A warning will indicate if a newer release is available.


A software update package (.wlup file) includes all files required to update the system. Some software updates also requires an update of the low-level FPGA image. The FPGA image is encrypted with a unique key. To generate a new FPGA image for your board, Water Linked needs to know the Chip ID of your board. The Chip ID can be found in the About tab of the GUI. To get the latest software package for your kit, go to and enter the Chip ID of your kit.
