This project contains all necessary files to build a custom OpenWRT image for Raspberry Pi model 4 or CM4 with the following additions to the oficial image:
- has all dependencies for Ansible support;
- supports RPi CM4 DFRobot Carrier Board Mini.
The latest Raspberry Pi 4 compatible image can be downloaded from the official OpenWRT website from the target bcm2711
Custom OpenWRT images can be created with the official bcm2711 image builder. This image builder is stored in the same folder with the original build openwrt-imagebuilder-bcm27xx-bcm2711.Linux-x86_64.tar.xz.
The builder requires Linux-based operating system running on x86_64 CPU.
Vagrant prepares a virtual Debian host using Ansible playbook for building a new image. It uses VirtualBox as a provider for virtual hosts.
The build.sh script downloads all necessary files on the virtual host, runs all build steps and returns the final build to the workstation.
If your workstation is a linux host, you don't need a virtual machine and can execute scripts/build.sh directly from the repo's root folder.

Install all dependencies before moving forward
- Vagrant
brew install vagrant - Ansible
brew install ansible - VirtualBox can be downloaded from https://www.virtualbox.org
- Note: ARM64(aka Apple CPU) hosts are not supported at the moment
Clone the builder repo:
git clone https://github.com/mkoshtenko/openwrt-builder.git
cd openwrt-builder
Setup the infrastructure:
vagrant up
Create build:
vagrant ssh -c './scripts/build.sh'
Clean up:
vagrant destroy
The image file should be in ./builds directory, e.g. ./builds/openwrt-rpi-4.img.gz
Run Ansible playbook w/o destroying the deployment:
vagrant provision
