Software Update Mechanisms: Selecting the Best Solution for Your Embedded Linux Device
August 18, 1 pm EDT
Updating device software has always been a complicated process. Today, widespread use of connected IoT device fleets, along with escalating concern over cybersecurity, has made that process even more complex. Fortunately, there are a number of well-established open source solutions to help you address software update needs. But, with so many options, how do you determine which solution is right for your device?
This webinar will provide the foundation you need to make an informed decision. We’ll examine several different industry approaches, including A/B updates with a dual-redundant scheme, delta updates, container-based updates and combined strategies, as well as the leading technologies that support these approaches. Open source technologies such as Mender, RAUC and libostree-based solutions implement these strategies and provide tools to manage updates of multiple devices.
We’ll also review a variety of open source Linux software update technologies, and offer practical examples for integrating them using the Yocto Project and OpenEmbedded. In order to help you better understand the strengths and weaknesses of each technology, we’ll deep dive into various real-world use cases, including leveraging CAAM (Cryptographic Accelerator and Assurance Module) hardware on Freescale i.MX6 hardware for encrypted and signed updates and using Microsoft Azure IoT to host software updates from the cloud.
