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. + + +## License + +This project is licensed under the MIT License.
