Hi Bruce,
I've got another question. I know that in a .bbappend I can specify functions
to run during the build procedure, would it be possible to add in a function
that would run after the do_configure_prepend() in the linux-rpi.inf file? If I
could do that, then I could modify the config file that is produced by that
...prepend() function.
Yep. You can specify routines like that. You just need to get the
content and ordering right to do what you want.
Bruce
Or the other option is to modify the linux-rpi.inc file itself.

Hi Bruce,
Thanks for all of your help in looking into this. I did get another response
that
detailed using an out of tree defconfig. They didn't know if it would work with
Morty,
they are using it with Sumo. I'll have to try it with Morty.
Thanks again,

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-raspber
ry
pi/
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.

Greg Wilson-Lindberg

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.

Yocto is seeing my request to change the kernel config, suggests
that the change is acceptable, but then doesn't make it.
Thanks in advance for any insight,
Greg
