Explore embedded update tools and real-world experiences in this Birds of a Feather (BoF) session led by Jan Lübbe from Pengutronix. Begin with an overview of open-source update tools and servers before engaging in an open discussion on user experiences and unsolved problems. Delve into topics such as multiple signatures, successful update detection, automated testing, delta-updates for bandwidth-constrained devices, user data migration, and peer-to-peer update distribution. Gain insights from Lübbe's extensive background in Linux smartphones, open-source GSM networks, and kernel development. Participate in this collaborative session to address challenges and share knowledge about embedded update tools across various platforms and use cases.
