The Yocto Project is a collaborative Open Source project that provides templates, tools and methods to help create custom Linux-based systems for embedded products, regardless of the hardware architecture. It was founded in 2010 as a collaboration among hardware manufacturers, open-source operating systems vendors, and electronics companies to help standardize embedded Linux development. This talk will present an introduction to the Yocto framework, starting with an overview of Yocto including its advantages and limitations as compared to other approaches for building an embedded Linux image. It will describe the major components of Yocto, including what it provides and the tools and components it offers to create embedded Linux systems. An example will be given of creating a Yocto image for the Beaglebone, a low-cost ARM development board. The steps will include building the OS image, creating an SDK for cross-compilation, and deploying the image to the board. It will introduce key tools including bitbake and its related configuration files as well as the graphical “toaster” tool. The development platform used will be a Linux-based desktop system. We’ll wrap things up with some suggestions on how to get started using Yocto and a list of references to more information including web sites and published books. Attendees will gain a good overall understanding of what Yocto provides, the advantages it offers, and the basic process for using it to create an embedded Linux distribution. No previous experience with Yocto will be assumed, although a general understanding of embedded systems development is useful.
