[OE-core] bzImage not included in rootfs

[Chiz Chikwendu]

Hi Scott,

Thanks for your help. 

I went another route. In my layer, I created an image.bb file. 
The .bb file tells yocto to include the kernel in the rootfs. I do this with the command:
IMAGE_INSTALL += kernel-image
IMAGE_INSTALL += kernel-module

This installs the kernel image and module in the rootfs. 
I can also try your suggested method.

Hi Chiz,

Which MACHINE are you building for? This is probably something that is
set in the machine's BSP, since some hw platforms use bootloaders which
look for the kernel in a separate flash disk than the rootfs, so for
those devices there's no need to put the kernel in the rootfs.

If you're building one of the qemu machine targets, note that in
meta/conf/machine/include/qemu.inc there is:

# Don't include kernels in standard images
RDEPENDS_kernel-base = ""

Finally, where are you trying to set RDEPENDS_kernel-base in your
example above? I'm assuming in your local.conf file? I believe that
should be the place to do it so that it overrides the machine
configuration's definition.

Finally, make sure you've cleared the build cache for the image
generation by running bitbake -c cleanall <image-name> before trying to
generate it again.

Scott
