Overview

The Yocto Project is an project that intends to provide an OpenSource build system, based on top of Poky and Open Embedded, that enables developers to create their own linux distribution specific to their environment. To ease this even further, Yocto offers some templates of different sizes (tiny to fullblown), which the developer can adapt (extend or shrink) by the simple means of editing some configuration files.

Internally Yocto uses bitbake recipes which are quite similar to Gentoo's ebuild system, so adding new packages or modifying packages is quite easy.

When Yocto is then run, it takes care of fetching the sources, compiling, packaging and creating the image, but also provides the developer with a toolchain for cross compilation and a Application Developer Kit (ADK) tailored to his own distribution. Depending on the configuration, the created image can then be deployed directly onto the target hardware or emulated via qemu.

Unfortunately Yocto currently leaves out the bootloader part of the system, "as this should be provided by the board vendor".

It currently supports x86, x86_64, ARM, PowerPC and MIPS.

Yocto intends to work closely with the upstream projects - e.g. updating the kernel at least once every 6 months for regular releases, but also providing the possibility to run the latest git version of the kernel - and tries to be software and vendor agnostic - thus you can e.g. choose which package manager format you intend to use in your embedded linux distribution (deb, rpm, ipkg).

Yocto has also an excellent integration into the Eclipse IDE, and allows you to do most of the necessary steps from within Eclipse.
