Evolution of (OTA) Update in the IoT World
summary
SWUpdate is a FOSS update agent that already handles delta updates (via librsync-style diffs), signed meta descriptions, and storage-aware installs for kernels, bootloader environments, FPGA bitstreams and MCU firmware; it adds a compound image format plus a gateway handler that uses a REST API and WebSocket to push and monitor per-controller installs across a ship engine network and to auto-provision replacement controllers. Factory provisioning supports a factory mode workflow. Builds integrate with Yocto/bitbake and Debian, tests use Tabata/Jenkins, and security audits report fixable issues. SWUpdate supports skipping unrelated artifacts to save bandwidth.
