Hi Bruce,
I've been able to reproduce the problem in a more minimal environment.
To build a basic Yocto Raspberry Pi environment I based my build on the
instructions found here:
https://themeaningfulengineer.github.io/exploring-yocto-with-raspberrypi/
The steps that I actually executed are:
git clone -b morty --single-branch git://git.yoctoproject.org/poky
cd poky/
git clone -b morty http://git.yoctoproject.org/git/meta-raspberrypi
source oe-init-build-env rpi-build
In rpi-build/conf/local.conf I changed the MACHINE assignment to "raspberrypi2" from
"qemu86"
In rpi-build/conf/bblayers.conf I added " /home/gwilson/Qt/poky/meta-raspberrypi
\" to pick up the raspberry layer.
At this point I ran:
bitbake rpi-hwup-image
to verify that the environment was correct. The build finished with only a
couple of warnings about checksum problems and using alternate mirrors.
I then copied in my kernel scripts and added in the directory to the bblayers
file.
When I rebuilt with these changes I get the same warnings/errors about changing
the kernel config that I get with my full build environment.
I've attached my meta-test directory with the kernel configuration .bbappend and .scc
& .cfg files, and the final bblayers.conf & local.conf files.
Thanks for the layers and cut & paste instructions. They helped
a lot.
.. even with that start, it took me a bit to figure things out.
In the end, I can't actually figure out how to get the fragment
working with the rpi kernel configuration routines as they stand
in the morty timeframe.
in recipes-kernel/linux/linux-rpi.inc, there's a do_configure_prepend
routine who's first action is to clear ${B}/.config .. which is where
the kernel-yocto bbclass would have put the merged config + fragment.
(The defconfig is also a placeholder defconfig, I could work around
that, but in the end, it doesn't matter since that routine zeros out
anything that has merged).
So as I see it, you'll either need to carry your own defconfig, patch
the in-tree defconfig that is used, or write routines in your bbappend
to modify the configuration directly. I admit to not looking to see
if the techniques to do this are described anywhere, since I was just
trying to sort out why the fragment wasn't being properly applied.
Sorry I couldn't be of more help.
Cheers,
Bruce
Thank you for taking a look at this.

I can't tell from the information provided.
But if you can send me a set of layers to clone, and configure locally, I can
figure it
out.
