## Using
The most common way of using this Nerves System is create a project with `mix
nerves.new` and to export `MIX_TARGET=rock_5bp`. See the [Getting started
guide](https://hexdocs.pm/nerves/getting-started.html#creating-a-new-nerves-app)
for more information.
If you need custom modifications to this system for your device, clone this
repository and update as described in [Making custom
systems](https://hexdocs.pm/nerves/customizing-systems.html).
## Supported WiFi devices
The Radxa Rock 5B+ comes with a Realtek RTL8852BE WiFi/BT module. Unfortunately,
there's no driver in the radxa kerenl (6.1) for this device. So, we're using an out-of-tree
driver `rtw89`.
Currently the module is not loaded automatically. To load the driver, run the following command:
```elixir
cmd "modprobe rtw89_8852be_git"
```
## Linux kernel configuration
The Linux kernel compiled for Nerves is a stripped down version of the default
Radxa Linux kernel. This is done to remove unnecessary features, select
some Nerves-specific features like F2FS and SquashFS support, and to save space.
