# openwrt-builder
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](https://wiki.dfrobot.com/Compute_Module_4_IoT_Router_Board_Mini_SKU_DFR0767).
The latest Raspberry Pi 4 compatible image can be downloaded from the official OpenWRT website from the target [bcm2711](https://downloads.openwrt.org/snapshots/targets/bcm27xx/bcm2711/)
## How it works
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.
## Hardware RPi-4 setup
```

## OSX Steps
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`
## Troubleshooting
Run Ansible playbook w/o destroying the deployment:
```
vagrant provision
```
