## Targets
|
||
|
|
|
||
|
|
Nerves applications produce images for hardware targets based on the
|
||
|
|
`MIX_TARGET` environment variable. If `MIX_TARGET` is unset, `mix` builds an
|
||
|
|
image that runs on the host (e.g., your laptop). This is useful for executing
|
||
|
|
logic tests, running utilities, and debugging. Other targets are represented by
|
||
|
|
a short name like `rpi3` that maps to a Nerves system image for that platform.
|
||
|
|
All of this logic is in the generated `mix.exs` and may be customized. For more
|
||
|

## Getting Started
|
||
|
|
|
||
|
|
To start your Nerves app:
|
||
|
|
* `export MIX_TARGET=my_target` or prefix every command with
|
||
|
|
`MIX_TARGET=my_target`. For example, `MIX_TARGET=rpi3`
|
||
|
|
* Install dependencies with `mix deps.get`
|
||
|
|
* Create firmware with `mix firmware`
|
||
|
|
* Burn to an SD card with `mix firmware.burn`
|
||
