+ Each release of the Yocto Project provides a few Linux
+ kernel recipes from which you can choose.
+ These are located in the
+ Source Directory
+ in meta/recipes-kernel/linux.
+
+
+
+ To begin with, create a minimal, custom layer from which you
+ can work.
+ See the
+ "Get Your Layer Setup for the Build" section
+ of the Yocto Project Development Manual for information.
+
+
+
+ Next comes the .bbappend file.
+ You create this file in your custom layer.
+ You also name it accordingly based on the linux-yocto recipe
+ you are using.
+ For example, if you are modifying the
+ meta/recipes-kernel/linux/linux-yocto_3.4.bb
+ recipe, the append file will typical be located as follows
+ within your custom layer:
+
+ <your-layer>/recipes-kernel/linux/linux-yocto_3.4.bbappend
+
+ The append file should initially contain the following text:
+
+ FILESEXTRAPATHS := "${THISDIR}/${PN}"
+
+ The path ${THISDIR}/${PN} expands
+ to "linux-yocto" in the current directory for this example.
+ If you add any new files that modify the kernel recipe, you need
+ to place them in your layer in the following area:
+
+ <your-layer>/recipes-kernel/linux/linux-yocto/
+
+ If you are working on a new machine Board Support Package
+ (BSP), be sure to refer to the
+ Yocto Project Board Support Package (BSP) Developer's Guide.
