Kernel selection using yocto
Select which kernel to build in your machine configuration, see BSP manual and for example stackoverflow question
Basically, for selecting kernel you can add
PREFERRED_PROVIDER_virtual/kernel = "my-kernel-recipe"
To your mymachine.conf
.
You should have or create kernel bb layer for having kernel source.
Once you have kernel source, add following in your local.conf file.
PREFERRED_PROVIDER_virtual/kernel ?= "<bb_layer_name>"
PREFERRED_VERSION_<bb_layer_name> ?= "<version>"
E.g.
mkdir -p meta-imx/recipes-kernel/linux/linux-imx_4.11.bb
add whatever you want in bb file.
vi build/local.conf
# kernel preference
PREFERRED_PROVIDER_virtual/kernel ?= "linux-imx"
PREFERRED_VERSION_linux-imx ?= "4.11%"
Once you are good with it you can merge build/local.conf to your target such as local.conf.sample or what ever name you have given.
