Gaisler Buildroot

We provide Gaisler Buildroot  distributions, aimed for both LEON and NOEL, based on LTS versions of the open-source Buildroot tool.. Buildroot is developed by the community at buildroot.org. Gaisler Buildroot is our officially supported Linux development and build environment. It can automatically download all needed LEON utilities, be used to configure, develop and build both kernel and user space environment, produce RAM images with MKLINUXIMG, and create bootable ROM images from the RAM images with MKPROM. Similarly for NOEL it can download and build everything needed and produce loadable RAM images using OpenSBI.

Buildroot targets embedded systems supporting GLIBC, which makes it suitable for the typical LEON or NOEL user. It supports several hundreds of useful userspace applications which can be automatically included in the generated root file system as selected by the user. Our Gaisler Buildroot environment makes it easy to get started with default configurations ready to build example RAM images with both kernel and RAM file system, and to be used as a starting point.

LEON and NOEL specific documentation about Buildroot is found in the Gaisler Buildroot User's Manual. The general Buildroot manual is included in the Gaisler Buildroot release.
