nrmmota / buildroot-external

A buildroot configuration with helper scripts for using br2-external trees. Not supported by or endorsed by the buildroot project. See http://buildroot.org for information about the buildroot project.

Buildroot Base Project Template

This is an example based project template for buildroot. It uses an br2-external configuration file storage and the official buildroot repository as a git submodule. Scripts are provided to make it easy to perform a build, save configuration, or start the build using qemu.

Installing Dependencies

Run ./install_ubuntu.sh to install any dependencies. This should work on Ubuntu or on the vagrant container referenced on the Buildroot Manual startup page.

Building

Run ./build.sh to build the image. This script is currently hard-coded to use an x86_64 default build target config. The config will only be updated when the .config file does not exist. When pulling in configuration changes, delete the buildroot/.config file before running the build script. This will require a complete rebuild.

Starting Qemu

Typically you will want to open a new screen. session using screen -S qemu or similar before starting QEMU. Then from this screen session, run ./start_qemu.sh. To detach, use Ctrl-a d. You can reconnect to this screen later using screen -r qemu. When you want to stop the qemu target, use pkill qemu

Saving Configs

When you make changes to buildroot configuration files, run ./save_configs.sh to export these configurations to the br2-external tree for commit.
