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.

Installation

It's published in Hex, so..

  1. Add nerves_firmware to your list of dependencies in mix.exs:

     def deps do
       [{:nerves_firmware, "~> 0.4.0"}]
     end
    
  2. Ensure nerves_firmware is started before your application:

     def application do
       [applications: [:nerves_firmware]]
     end
    

Usage

in config.exs you can configure the block device and signing of the firmware.

use Mix.Config

config :nerves_firmware,
  device: "/dev/mmcblk0",
  pub_key_path: "/etc/fwup-key.pub"
