SWUpdate is a Linux Update agent with the goal to provide an efficient and safe way to update an embedded Linux system in the field. SWUpdate supports local and OTA updates and multiple update strategies and it is designed with security in mind. To start with SWUpdate, it is suggested you look at the documentation and build for one evaluation board (or you run SWUpdate on your host for a first overview). If you plan to update your device locally or remotely, SWUpdate is the right framework for you. Thanks to its high flexibility, you can tune any aspect of the update and integrate it into your project. SWUpdate does not set any special requirement and it can be integrated in any embedded Linux project. It does not matter if you want to update from a local USB stick, or via a Webserver, or via fleet management – SWUpdate will fit your needs.
