Following the same trend of consumer electronics,safety-critical industries are starting to adopt Over-The-AirSoftware Updates (OTASU) on their embedded systems. Themotivation behind this trend is twofold. On the one hand,OTASU offer several benefits to the product makers and usersby improving or adding new functionality and services to theproduct without a complete redesign. On the other hand, theincreasing connectivity trend makes OTASU a crucial cybersecuritydemand to download latest security patches. However,the application of OTASU in the safety-critical domain is notfree of challenges, specially when considering the dramaticincrease of software complexity and the resulting high computingperformance demands. This is the mission of UP2DATE, arecently launched project funded within the European H2020programme focused on new software update architectures forheterogeneous high-performance mixed-criticality systems. Thispaper gives an overview of UP2DATE and its foundations, whichseeks to improve existing OTASU solutions by considering safety,security and availability from the ground up in an architecturethat builds around composability and modularity.
