Setting up the base for the project
First, we should set up the base for our Yocto Project implementation. Most of the techniques used in this section have been covered throughout the book, so they will not be explained in detail. In this part of the chapter, we perform the basic setup for our Yocto Project implementation, which will be used for the home automation project.
Creating a new layer
We will begin by creating a new layer. The new layer will act as the base of our home automation project. For now, it will only contain our image recipe, but we will add more content to the layer throughout the chapter until we have all the parts needed for our server. Just as described in Chapter 7, Deploying a Custom Layer on the Raspberry Pi, we will use yocto-layer to help us set up the structure of the layer. We need to set a high priority to ensure that content from this layer is prioritized over, for example, content in meta-raspberrypi, like so:
$ /path/to/poky/scripts/yocto-layer create packt...
