The bug you filed needs to get fixed, when it does, the MACHINE_FEATURES
+= "bluetooth" combined with the stock linux-yocto kernel will combine
with the definition of task-base-bluetooth to give you what you are
looking for.
See meta/recipes-core/tasks/task-base.bb:
RDEPENDS_task-base-bluetooth = "\
bluez4 \
"
RRECOMMENDS_task-base-bluetooth = "\
kernel-module-bluetooth \
kernel-module-l2cap \
kernel-module-rfcomm \
kernel-module-hci-vhci \
kernel-module-bnep \
kernel-module-hidp \
kernel-module-hci-uart \
kernel-module-sco \
${@base_contains('COMBINED_FEATURES', 'usbhost',
'kernel-module-hci-usb', '',d)} \
${@base_contains('COMBINED_FEATURES', 'pcmcia',
'kernel-module-bluetooth3c-cs', '',d)} \
${@base_contains('COMBINED_FEATURES', 'pcmcia',
'kernel-module-bluecard-cs', '',d)} \
${@base_contains('COMBINED_FEATURES', 'pcmcia',
'kernel-module-bluetoothuart-cs', '',d)} \
${@base_contains('COMBINED_FEATURES', 'pcmcia',
'kernel-module-dtl1-cs', '',d)} \
What this does is include the required kernel module packages created by
the linux-yocto recipe in the package feed for your image.
Saul mentioned he would try and have a look at that bug, CC'ing him for
reference. Looking at that bug though, I see Richard has commented:
http://bugzilla.yoctoproject.org/show_bug.cgi?id=1814
Can you try with his suggestion, using:
MACHINE_FEATURES_append_crownbay = " bluetooth"
I believe the assignment you were using before explains why you hit the
original modutils-depmod failure. See:
$ git grep modutils-depmod
meta/recipes-kernel/update-modules/update-modules_1.0.bb:RDEPENDS_${PN}
= "${@base_contains("MACHINE_FEATURES", "kernel26",
Note that the recipe depends on kernel26 being part of MACHINE_FEATURES,
since you set MACHINE_FEATURES to "bluetooth", it failed to build.
