Introduction

Once we have our build environment ready with the Yocto project, it's time to think about beginning development work on our embedded Linux project.

Most of the embedded Linux projects require both custom hardware and software. An early task in the development process is to test different hardware reference boards and the selection of one to base our design on. We have chosen the Wandboard, a Freescale i.MX6-based platform, as it is an affordable and open board, which makes it perfect for our needs.

On an embedded project, it is usually a good idea to start working on the software as soon as possible, probably before the hardware prototypes are ready, so that it is possible to start working directly with the reference design.

But at some point, the hardware prototypes will be ready and changes will need to be introduced into Yocto to support the new hardware.

This chapter will explain how to create a BSP layer to contain those hardware-specific changes, as well as show how to work...
