In Chapter 10, Exploring External Layer, we learned that the Yocto Project allows for the split of its metadata among different layers. It organizes the metadata so we can choose which exact meta layer to add to our project.
The way to find the BSP for a board varies, but generally we can find it by visiting http://layers.openembedded.org/. We can search for the machine name and the website finds on its database which layer contains it.
In the next sections, we will describe the steps needed to go from source code to the final binary to be copied to the board. Feel free to skip a section if the board isn't available to you.
