v0.13.11

This change adds a simple firmware validator for Nerves devices that validate their firmware the first time it's run. It's optional and the default is to not use it. This is useful for all Nerves systems that require validation on boot and is intended to ease the change on the Raspberry Pi "2.0" Nerves systems.

The simple firmware validator only checks that all OTP applications have started up successfully. If you already have a firmware validator, you can just ignore this.

If you don't know if you need a firmware validator, you likely don't since your device boots with the assumption that the firmware will work. If you need to run fw_validate or Nerves.Runtime.validate_firmware/0 every time you load new firmware, then you'll want some code to do it automatically and this is an option.

See the main README.md and Nerves.Runtime.StartupGuard for integration with your project.

• Changes
  • Add Nerves.Runtime.StartupGuard
  • Fix new Elixir 1.20 warnings

v0.13.10

• Changes
  • Support overriding or disabling data partition initialization. See the :init_module option documentation.
  • Support passing extra options to fwup to enable fwup to run third party programs. See the :fwup_extra_options option documentation.
  • Defer Nerves KV loading until actually needed. This removes many unnecessary loads, but most importantly defers work that could potentially fail from early initialization. This allows it to fail in places that are easier to debug.
  • Support passing arguments to rngd and haveged if you're using them. See rngd_args and haveged_args in the application config. This is a rare use case especially since Linux kernels have improved their support for early entropy.
