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
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.
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:
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.
