Download

The latest stable release is 2014.05, which can be downloaded here:

buildroot-2014.05.tar.gz (PGP signature) or buildroot-2014.05.tar.bz2 (PGP signature).

You can also obtain Daily Snapshots of the latest Buildroot source tree if you want to to follow development, but cannot or do not wish to use Git.

Repository

The buildroot repository can be browsed online through cgit at http://git.buildroot.net/buildroot. To grab a copy of the repository use 
git clone git://git.buildroot.net/buildroot
Or if you're behind a firewall blocking git: 
git clone http://git.buildroot.net/git/buildroot.git

Please use the native git protocol if at all possible, as it's a lot more efficient than HTTP.

If you are not already familiar with using Git, we recommend you visit the Git website.

Once you've checked out a copy of the source tree, you can update your source tree at any time so it is in sync with the latest and greatest by entering your buildroot directory and running the command: 

git pull
Because you've only been granted anonymous access to the tree, you won't be able to push your changes to the repo. Changes can instead be submitted for inclusion by posting them to the buildroot mailing list.
