Hello,
I'm porting a kernel to use yocto-style build process. The kernel
fetches fine, but there's a problem with '.config' file generation. I'd
like to supply a 'defconfig' and a configuration fragment file
'test.cfg' (which should be overlayed on top of 'defconfig') from the
bitbake recipe. What I end up getting is a '.config' file that looks
like it used the default values - neither 'defconfig' nor 'test.cfg' was
used. Here's what I have going in my recipe:
The defconfig + fragment wouldn't have been ignored, but it is
also possible that other settings / fragments were applied that
are making it look like they were not applied.
Can you look at your kernel-source/.kernel-meta/bsp_definition
file, and see what was used as the entry point to the configuration ?
If something was generated by the system, it would be pulling in
the standard definitions/fragments.
Cheers,
Bruce

Configuration files are fetched as intended:

I've followed instructions from
https://www.yoctoproject.org/docs/2.5/kernel-dev/kernel-dev.html#creating-a-defconfig-file
and
https://www.yoctoproject.org/docs/2.5/kernel-dev/kernel-dev.html#creating-config-fragments.
Am I doing something wrong here?
