The AUTOSAR standard describes an architecture for embedded automotive systems. The lack of flexibility is a major drawback of this architecture and updates are not easily possible. In our work we explore the various facets of software updates in the context of AUTOSAR embedded applications. With few modifications that remain compatible with the development process, we propose specific concepts for updates. Such updates can be remotely achieved, for maintenance and/or evolution purposes. As functional updates may lead to safety mechanisms updates, we also highlight how safety mechanisms can be added or updated with different level of granularity. We illustrate these concepts and capabilities with a simple case study as a proof of concepts. We finally draw the lessons learnt from this work.
