Automotive OTA technology with differential system

By eeNews Europe



Keeping updates as small as possible reduces distribution time and cost, update transmission time, and memory required on automotive ECUs. Efficient differential updates are important for a successful, production-grade automotive OTA solution. Edge Sync is a modular, end-to-end OTA update and software lifecycle management solution that allows fast, safe, and secure updates to software and firmware.

Edge Sync differential system technology includes:

• Patch streaming: Stream smaller chunks of updates when memory on the target ECU is insufficient to store the full differential update

• Patching in place: Optimize for low memory/performance ECUs, enabling the application of the update within a single active memory partition

• A/B updates: Write to a secondary, inactive memory partition to apply the patch

• Pause and resume: Allow the installation to be paused and resumed from exactly where it left off, eliminating the need to restart from scratch

• Reduced memory footprint of software client: Configurable software client that enables optimization for resource-constrained environments, including adding/removing functionality as needed to support only the relevant use cases for a given ECU
