We are now switching our images to OpenSoar. Far-reaching and sensible changes have been made here both in the image for the OpenVario and in OpenSoar (offshoot of XCSoar). The most obvious thing is that the OpenVario start menu no longer exists and has been meaningfully integrated into OpenSoar. It is also very important that all settings are now saved in a third partition of the SD card. This partition is not touched during the update, so your device retains all settings after an update. There are many other differences, but it’s best to just give it a try.

The images published here currently differ slightly from those published by Uwe and are only useful in conjunction with a FreeVario. If you don’t have FreeVario, we recommend Uwe’s images. https://opensoar.de/releases/

The most important difference is the new version of the FreeVario driver, which Uwe will soon incorporate into the official OpenSoar. As soon as these developments are incorporated into the official release of OpenSoar, our images will expire here. 

If you want to update from one of the old images to this version, you first have to load a special version of Uwe and enter a few commands using the keyboard in the terminal. As this is explained here: OpenVario-Upgrade

You can then drag the image from here to your USB stick and run the update in the OpenSoar menu under OpenVario. So you never have to remove the SD card for an update again!

You will also find everything you need to build here. All data is also published in GitHub: https://github.com/freevariode/FreeVarioGauge
In the GitHub, you can find the older files in particular, in case you need access to the old files again.
