KaeilOS
KaeilOS is an embedded linux GNU/GPL distribution composed of a collection of the best publicly available Open Source packages. Version 4.00 available since January 2009 has joined OpenEmbedded project offering a wider selection of packages and recipes.
The OpenEmbedded Project (OE for short) is a software framework to create Linux distributions aimed for embedded devices. Primarily, the project maintains and develops a collection of BitBake recipes. The bitbakes consist of the source URL of the package, dependencies and compile or install options. During the build process they are used to track dependencies, cross-compile the package and pack it up, suitable to be installed on the target device. It’s also possible to create complete images, consisting of root file system and kernel. As a first step the framework will build a cross-compiler toolchain for the target platform.
