As we saw, Poky metadata starts with the
meta-yocto-bsp layers, and it can be expanded by using more layers.
An index of the available OpenEmbedded layers that are compatible with the Yocto project is maintained at http://layers.openembedded.org/.
An embedded product's development usually starts with hardware evaluation using a manufacturer's reference board design. Unless you are working with one of the reference boards already supported by Poky, you will need to extend Poky to support your hardware.
The first thing to do is to select which base hardware your design is going to be based on. We will use a board that is based on a Freescale i.MX6 System on Chip (SoC) as a ...
