[yocto] Kernel config fragments are not applied

[Neuer User]

Hello

I am trying to add a custom kernel config to my layer. I followed the
following guide:
http://www.yoctoproject.org/docs/1.6/dev-manual/dev-manual.html#creating-config-fragments

I have the following files in my layer:

recipes-kernel/linux/linux-cubox-i_3.0.35.bbappend:

FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}-${PV}:"

inherit kernel
COMPATIBLE_MACHINE_cubox-i = "(cubox-i)"

SRC_URI += "file://videoin.cfg"


recipes-kernel/linux/linux-cubox-i-3.0.35/videoin.cfg:

CONFIG_VIDEOBUF_VMALLOC=y
CONFIG_VIDEO_TVEEPROM=y
CONFIG_VIDEO_TUNER=y
CONFIG_VIDEO_ADV7180=y
CONFIG_VIDEO_MXC_CAMERA=y
CONFIG_MXC_TVIN_ADV7180=y
CONFIG_USB_VIDEO_CLASS=y
CONFIG_USB_GSPCA=y
CONFIG_USB_M5602=y
CONFIG_USB_STV06XX=y
...

The layer is included in conf/bblayers.conf. The file videoin.cfg is
found and "installed" in the correct tmp/work directory. However the
config is never added to the kernel config file.

What am I doing wrong?

I use Yocto "master-next", cubox-i4pro.

Thanks

Michael
