I'm trying to change some kernel configuration flags in a raspberrypi3 Morty build and I get warnings that it isn't working.


Here is the build info and warnings:

Here is my linux-raspberrypi_4.4.bbappend for the kernel:

# Scribe additions to Kernel configuration

FILESEXTRAPATHS_prepend := "${FILE_DIRNAME}/files:"
FILESEXTRAPATHS_prepend := "${FILE_DIRNAME}/${PN}:"

SRC_URI += "file://Scribe.scc"
SRC_URI += "file://mcp251x.c.patch"



The Scribe.scc file:

# Scribe additions to kernel configuration
kconf hardware Scribe.cfg



And the Scribe.cfg file:

# Scribe additions to kernel configuration

# Enable MAX9768
#CONFIG_SOC_ALL_CODECS=m
#CONFIG_COMPILE_TEST=y
CONFIG_SND_SOC_MAX9768=y

# Enable MAX11606
#IIO=y
CONFIG_MAX1363=m

# Enable EMS CPC-USB
CONFIG_CAN_EMS_USB=m


Here is my directory tree:

Qt-5.9.6

     Yocto-mirror                                                     # Yocto build mirror
     Yocto-build-RPi3                                              # Yocto build root
                build-raspberrypi                                   # build directory
                sources                                                 # yocto sources
                       meta-sakura                                   # our recipes
                               recipes-kernel                        # directory for kernel changes
                                       linux                               # directory that contains linux-raspberrypi_4.4.bbappend
                                              files                         # directory that contains .scc & .cfg files

As seen above none of the changes are accepted although there is nothing that blocks any of them.

Any help understanding this would be greatly appreciated.
