The Source Directory
contains both general layers and BSP
layers right out of the box.
You can easily identify layers that ship with a
Yocto Project release in the Source Directory by their
folder names.
Folders that represent layers typically have names that begin with
the string meta-
.
meta-
, but it's a commonly accepted
standard in the Yocto Project community.
For example, when you set up the Source Directory structure,
you will see several layers:
meta
, meta-hob
,
meta-skeleton
,
meta-yocto
, and
meta-yocto-bsp
.
Each of these folders represents a distinct layer.
As another example, if you set up a local copy of the
meta-intel
Git repository
and then explore the folder of that general layer,
you will discover many Intel-specific BSP layers inside.
For more information on BSP layers, see the
"BSP Layers"
section in the Yocto Project Board Support Package (BSP)
Developer's Guide.
