[bitbake-devel] source modification and re-build

[nousi]

Hi,

kernel image name is "uImage-nousi-linux.img" in
"poky/build/tmp/deploy/images/nousi12k/" directory when I use "bitbake
nousi-dev-image", it will create all the images including rootfs,
u-boot, dtb and takes lot of time to build.

I would like to build only kernel image "uImage-nousi-linux.img".
Please, let me know how can I do it.

Thanks,
Nousi.
