The embedded-update crate implements a firmware update protocol for embedded devices connected to a firmware update service, which works in no_std (bare metal) environments.
Both the device to be updated and the update service are pluggable, so the protocol can be used with any device 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 multiple devices.
The library provides an InMemory update service reference implementation, and a Simulator reference implementation for devices.
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.
An implementation for Drogue Cloud can be found in Drogue Device.
Device side implementations can be found in Drogue Device.
embedded-update requires two features from nightly to compile:
generic_associated_typestype_alias_impl_traitThese features are complete, but are not yet merged to stable.
