Hello.
First you need to reconfigure your kernel configuration (ncurses must be
properly installed in your host PC):
$ bitbake -c menuconfig virtual/kernel
After you need to generate a fragment.cfg (containing a diff betweeen your
default and your recently customized kernel config):
$ bitbake -c diffconfig virtual/kernel
Thak will generate the fragment.cfg fine into your ${WORKDIR}
Then you need to create a bbappend in your own BSP layer extending the
content of your working kernel recipe. Something similar to this:
$ cat your-custom-bsp-layer/recipes-kernel/linux/linux-kernel_%.bbappend
FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"
SUMMARY = "Linux kernel customization for your board"
LINUX_VERSION = "x.y.z"
inherit kernel
SRC_URI += " \
file://fragment.cfg \
"
Just replace x.y.z by your specific kernel version. The fragment.cfg file
must be available inside your own kernel recipe, in a directory named ${PN}
(as indicated by FILESEXTRAPATHS_prepend):
$ ls your-custom-bsp-layer/recipes-kernel/linux/linux-kernel
fragment.cfg
Then you already can build your new kernel:
$ bitbake virtual/kernel
Hope this helps!
