- Consider a BSP that uses the <filename>linux-yocto-stable_git.bb</filename> kernel,
+ Supppose you use a BSP that uses the <filename>linux-yocto-stable_git.bb</filename> kernel,
which is the preferred kernel to use for developing a new BSP using the Yocto Project.
+ In other words, you have selected the kernel in your
+ <filename><bsp_name>.conf</filename> file by adding the following statement:
+ <programlisting>
+PREFERRED_PROVIDER_virtual/kernel ?= "linux-yocto-stable"
+ </programlisting>
You would use the <filename>linux-yocto-stable_git.bbappend</filename> file to append
specific BSP settings to the kernel, thus configuring the kernel for your particular BSP.

- Consider an example for the existing "crownbay" BSP.
- The append file used for the "crownbay" BSP is:
+ Now take a look at the existing "crownbay" BSP.
+ The append file used is:
<programlisting>
meta-crownbay/recipes-kernel/linux/linux-yocto-stable_git.bbappend
</programlisting>
The file contains the following:
<programlisting>
FILESEXTRAPATHS := "${THISDIR}/${PN}"
-COMPATIBLE_MACHINE_crownbay = "cronwbay"
+COMPATIBLE_MACHINE_crownbay = "crownbay"
KMACHINE_crownbay = "crownbay"
</programlisting>
This append file adds "crownbay" as a compatible machine,
For example, suppose you had a set of configuration options in a file called
<filename>defonfig</filename>.
If you put that file inside a directory named
- <filename class='directory'>/linux-yocto-stable_git</filename> and then added
+ <filename class='directory'>/linux-yocto-stable</filename> and then added
a SRC_URI statement such as the following to the append file, those configuration
options will be picked up and applied when the kernel is built.
