Nerves.Firmware

Elixir API for upgrading and managing firmware on a Nerves device.

Looking for over-the-network firmware updates? see nerves_firmware_http, which provides an HTTP micro-service providing over-network firmware management.

Leans heavily on Frank Hunleth's excellent fwup, which is included of the standard Nerves configurations.
