Building Android Auto Wireless

This repository contains a docker setup to make the build process easy.

If you choose to build without Docker, refer the Buildroot user manual for more details on dependencies and setup.

Clone

$ git clone --recurse-submodules https://github.com/kronflux/WirelessAndroidAutoDongle

Build with Docker

$ docker compose run --rm rpi4 # See docker-compose.yml for available options.

You can use rpi0w, rpi02w, rpi3a or rpi4 to build and generate an sdcard image. Once the build is successful, it'll copy the generated sdcard image in images/ directory.

You can also use the bash service for more control over the build process and experimentation.

$ docker compose run --rm bash

Build with manual setup

Once you have a recursive clone, you can manually build using the following set of commands.

$ cd buildroot
$ make BR2_EXTERNAL=../aa_wireless/ O=output/rpi0w raspberrypi0w_defconfig # Change output and defconfig for your board
$ cd output/rpi0w
$ make

When successful, this should generate the sd card image at images/sdcard.img in your output directory. See the "Install and Run" instructions above to use this image.

Use one of the following defconfig for the board you intend to use:

  • raspberrypi0w_defconfig - Raspberry Pi Zero W
  • raspberrypizero2w_defconfig - Raspberry Pi Zero 2 W
  • raspberrypi3a_defconfig - Raspberry Pi 3A+
  • raspberrypi4_defconfig - Raspberry Pi 4
