Firmware updates for embedded devices

The embedded-update crate implements firmware update protocol for embedded devices connected to a firmware update service, which works in no_std environments.

Both the device to be updated and the update service are pluggable, so the protocol can be used with any device flash or service that implements the provided traits. This means you can use the library directly on an embedded device, or on a gateway that proxies requests across multiple devices.

The library provides the InMemory and Serial reference implementations of the UpdateService trait, and the Simulator and Serial implementations for the FirmwareDevice trait.

Update service and device implementations can be added to embedded-update when types and traits for interacting with device flash and network connections are more widely available.

Supported update services

• (builtin) Serial - implements a serial update protocol for a device, that can be used over UART, USB Serial etc.
• (builtin) InMemory - implements a hard coded update service that serves an update from memory.
• (external) Drogue Device HttpUpdater - implements an update protocol over HTTP using Drogue Cloud + Drogue Ajour.
• (external) Drogue Device LorawanService - implements an update protocol over LoRaWAN using Drogue Cloud + Drogue Ajour.

Supported devices

• (builtin) Serial - implements a serial update protocol allowing to talk to a device implementing this protocol over UART, USB Serial etc.
• (builtin) Simulated - implements a simulated device for testing update services.

Minimum supported Rust version (MSRV)

embedded-update requires a feature from nightly to compile when using the nightly flag.
