Installing CUL Firmware

The CUL-stick has a ATMega32U4 processor on board and it has to be loaded with firmware in order to work. There is a special CUL-firmware developed for NetHomeServer, which works together with the encoders and decoders in NetHomeServer and ProtocolAnalyzer.

The firmware is in a file called NetHomeCUL.hex. In order to install this firmware on the CUL-stick you need the FLIP-tool from Atmel.

Here is a step by step instruction for how to install the firmware from a Windows PC:

1. Install Flip

Dowload Flip from the Flip download site and install it, but don't start it yet.

2. Install USB-Drivers

This requires some dexterity… Unplug the CUL-Stick (if you have it plugged in). Locate the tiny button on the bottom just below the USB socket. Now you have to press this button while you plug in the CUL-Stick.
