[yocto] changing kernel config in Morty build

[Greg Wilson-Lindberg]

Does anybody else have any idea about what is going on here?

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

Subject: changing kernel config in Morty build


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<file:///\\Scribe.scc>"

SRC_URI += "file://mcp251x.c.patch<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

                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.
