Hi All,

Am new to yocto environment, please let me know the process to change
kernel source using "bitbake nousi-linux -c menuconfig".

I can able to make changes using "bitbake nousi-linux -c menuconfig" this
command but my changes were not included in the new re-built image.
Am using the development linux source code.
Any help is appreciated.

Hi Nousilal,

“bitbake -c menuconfig nousi-linux” is used for changing the kernel configs instead of modifying source code, you can run “bitbake -C compile -f nousi-linux ” to force rebuild with updated kernel configs.

To modify the source code, you can do it in tmp/work-shared/<machine>/kernel-source/, then run “bitbake -C compile –f nousi-linux” to rebuild new kernel image.


Best Regards,

Zhenhua

please, ignore my previous mail.
There was an issue with the option "-C", it should be "-c".

I have compiled modified kernel using " bitbake -c compile -f nousi-linux"
command but, it seems kernel image does not get update with new
configuration at below path.

"poky/build/tmp/deploy/images/nousi123k/"

Please, let me know if I am missing something in the process.

You forced a kernel compile only, after that you probably want to
re-generate the image ("bitbake <image-name>").

Note that this method of modifying kernel configuration is not how you'd do
it in production: See
http://www.yoctoproject.org/docs/current/kernel-dev/kernel-dev.html#generating-configuration-files
for how to create a defconfig or a config fragment and
http://www.yoctoproject.org/docs/current/kernel-dev/kernel-dev.html#changing-the-configuration
for configuring your kernel with them.

Re: 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.
