Downloading and flashing the firmware
● In OpenTX companion's preferences window, make sure the proper firmware is selected (OpenTX for
FrSky Taranis), and the language / options match your preference, then click the top Download button
and select a location for the file. This will automatically build and download the latest available version
of OpenTX for Taranis.
● Close the Preferences window, and select the Burn -> Write Flash memory command. Make sure your
radio is powered off and connected.
● Browse for the file you just downloaded. It will be recognised automatically and the version will be
displayed.
● If you wish to replace the radio's splash screen, you can either load one from a file or select it from the
available library, and click the "Substitute image in firmware" box.
● Click "Burn to TX".
● Once the progress bar is done and the success prompt is shown you can dismiss it and disconnect your
radio :)
● If you get an error about the dfu-util executable not being found, open the flashing tool settings with the
Burn -> Configure menu item. Browse for the dfu-util executable, which should be:
○ On Windows: In the OpenTX companion installation folder (by default C:\Program
Files\companion9x\dfu-util.exe on 32-bit systems, and C:\Program Files
(x86)\companion9x\dfu-util.exe on 64-bit systems).
○ On Mac OS: /opt/local/bin/dfu-util.
