By convention, Yocto layer names start with meta, short for metadata. A BSP layer may then add a bsp keyword, and finally a unique name. We will call our layer meta-bsp-custom.

There are several ways to create a new layer:

• Manually, once you know what is required
• By copying the meta-skeleton layer included in Poky
• By using the yocto-layer command-line tool

You can have a look at the meta-skeleton layer in Poky and see that it includes the following elements:

• A layer.conf file, where the layer configuration variables are set
• A COPYING.MIT license file
• Several directories named with the recipes- prefix with example recipes for BusyBox, the Linux kernel and an example module, an example service recipe, an example user management recipe, and a multilib example.
