hello,

   Thanks for the reply. I searched for what you have suggested, but it
looks like I am missing something here. I didn't see kernel.conf file I
have shared my bblayers.conf details also , please let me know what I am
missing here. I am using the yocto for the first time for kernel build.

Please suggest me if I am doing anything wrong here.

Below is the bblayers.conf file details:


 # POKY_BBLAYERS_CONF_VERSION is increased each time
build/conf/bblayers.conf
 # changes incompatibly
 POKY_BBLAYERS_CONF_VERSION = "2"
 BBPATH = "${TOPDIR}"

 BBFILES ?= ""
 BBLAYERS ?= " \

   /home/siddhu/Documents/yocto/sources/poky/meta \
   /home/siddhu/Documents/yocto/sources/poky/meta-poky \
   /home/siddhu/Documents/yocto/sources/poky/meta-yocto-bsp \
   /home/siddhu/Documents/yocto/sources/meta-openembedded/meta-oe \
   /home/siddhu/Documents/yocto/sources/meta-openembedded/meta-multimedia \
   /home/siddhu/Documents/yocto/sources/meta-openembedded/meta-python \
   /home/siddhu/Documents/yocto/sources/meta-openembedded/meta-networking \
   /home/siddhu/Documents/yocto/sources/meta-openembedded/meta-filesystems \
   /home/siddhu/Documents/yocto/sources/meta-cloud-services \
   /home/siddhu/Documents/yocto/sources/meta-selinux \
   /home/siddhu/Documents/yocto/sources/meta-virtualization\
   /home/siddhu/Documents/yocto/sources/meta-raspberrypi \
   "

Am I missing any layers here? Please suggest me.
