Open Source Summit + Embedded Linux Conference Europe 2020

Software update of fleets of embedded Linux IoT devices has always been an important part of any product. In the past years several high-quality open source solutions for end to end updates emerged. The Yocto Project is an open source collaborative project of the Linux foundation for creating custom Linux-based systems for embedded devices using the OpenEmbedded build system. This session will explore the integration in Yocto and OpenEmbedded of A/B and binary delta updates over the air or through a USB stick. Comparison of four popular solutions will be provided: OSTree (meta-updater), Mender (meta-mender), RAUC (meta-rauc) and SWUpdate (meta-swupdate). We will discuss the advantages of each technology, review real life use cases, for example in Automotive Grade Linux (AGL), and provide the exact steps for using them on a Raspberry Pi. The Yocto Project and OpenEmbedded have been already adopted by a wide variety of industries. However, different industries have different requirements for software updates. This presentation will help you select the most appropriate solution for your use case based on practical examples. The talk is appropriate for anyone, including beginners.
