The latest stable release is 2015.05, which can be downloaded here:
buildroot-2015.05.tar.gz (PGP signature) or buildroot-2015.05.tar.bz2 (PGP signature).
This and earlier releases (and their PGP signatures) can always be downloaded from http://buildroot.net/downloads/.
You can also obtain daily snapshots of the latest Buildroot source tree if you want to follow development, but cannot or do not wish to use Git.
Older versions can be downloaded from the release archive.
git clone git://git.buildroot.net/buildrootOr 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 pullBecause 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.
