ota-reference-design
A practical reference design for reliable and secure over-the-air updates on embedded Linux.
This repository is intended as an educational reference design. It demonstrates one possible approach to designing and implementing a reliable OTA update system for embedded Linux.
The project focuses on the engineering decisions behind OTA systems, including:
- update strategies;
- system and storage architecture;
- bootloader interaction;
- atomic updates;
- rollback and recovery;
- integrity verification and signing;
- testing and failure handling.
It is not tied to a specific OTA framework, hardware platform, or cloud provider.
Raspberry Pi may be used for practical demonstrations, but the underlying concepts are applicable to a broader range of embedded Linux devices.
This repository is not intended to be a production-ready framework. Instead, it is designed to explain the architectural principles, trade-offs, and failure scenarios that should be considered when building a real OTA system.
The repository is being developed incrementally as a structured series of articles, diagrams, architecture decisions, and practical examples.
