rpi0_2 tag

[tomazbracic]

Instructions on how to work with this tag were not working for me. I changed tag as suggested to rpi0_2 in command line and withing mix.exs, but somehow had issue with mix firmware.

In my mix.exs i added {:nerves_system_rpi3a, "~> 1.24", runtime: false, targets: :rpi0_2} and commented out the line for targets: :rpi3a

This is the output of the mix firmware command

I assume I have mis configuration issue, but from the docs on https://hexdocs.pm/nerves_system_rpi0_2/readme.html#using I didn't find any further suggestion on what to change.

Any suggestion is welcome.

Thnx.

In your project's mix.exs, take a look for nerves_pack in the dependency list. This looks like the error that you get when the targets specification for it doesn't include the target that you're building. That means that Elixir won't add the nerves_pack library to the Mix release that it makes. The fix is to add :rpi0_2 to your @all_targets list.
