conf/machine/<machine.conf> in my custom layer doesn't get parsed

conf/machine/<machine.conf> in my custom layer doesn't get parsed

[Isaac Nickaein]

Hi,

I've created a custom meta layer over poky rocko and added it to
bblayer.conf. I've also set the appropriate MACHINE value in
conf/local.conf:

MACHINE = "colibri-imx6"

There is a machine specific conf file in this meta layer, but it
doesn't get parsed. This file is located at
"conf/machine/colibri-imx6.conf" inside the meta layer.

By checking the output of

bitbake -e

it seems that other machine-specific conf files like
"meta-freescale-3rdparty/conf/machine/colibri-imx6.conf" are
referenced and parsed. But there is not even a reference to my
machine-specific conf file.

Should I set some variables that hint the bitbake to parse machine
specific files in my layer?

Bests,
Isaac

Have you defined BBPATH in your layer.conf correctly?

Thanks,

Hi Anuj,

I guess so. Here is relevant lines in layer.conf for BBPATH:


# We have a conf and classes directory, add to BBPATH
BBPATH .= ":${LAYERDIR}"

# We have recipes-* directories, add to BBFILES
BBFILES += "${LAYERDIR}/recipes-*/*/*.bb \
        ${LAYERDIR}/recipes-*/*/*.bbappend \
        ${LAYERDIR}/*.bb"

BBFILE_COLLECTIONS += "samim-saba"
BBFILE_PATTERN_samim-saba = "^${LAYERDIR}/"
BBFILE_PRIORITY_samim-saba = "99"


And there the layout of conf directory of my layer:

yocto@yocto-server:/opt/yocto/rocko-poky/poky/meta-samim-saba/conf$ find
.
./layer.conf
./machine
./machine/colibri-imx6.conf
yocto@yocto-server:/opt/yocto/rocko-poky/poky/meta-samim-saba/conf$

I hope that this machine name, colibri-imx6, isn't being used in some
other included layer as well ...

meta-freescale-3rdparty/conf/machine/colibri-imx6.conf? Can you try
changing the name?

Thanks,

You are a lifesaver. Bitbake was picking "colibri-imx6.conf" from
"meta-freescale-3rdparty" and ignored my conf.
I thought conf files can be overridden but apparently just one
machine-specific conf can be provided.

Thanks Anjug.


Here is more info if someone had the same problem:

I reordered the included layers in BBLAYERS variable defined in
conf/bblayers.conf so that my layer be at the top of the list:

BBLAYERS ?= " \
  ${BSPDIR}/meta-mylayer \
  ${BSPDIR}/meta \
  ${BSPDIR}/meta-poky \
  ${BSPDIR}/meta-openembedded/meta-oe \
  ${BSPDIR}/meta-openembedded/meta-python \
  ${BSPDIR}/meta-openembedded/meta-networking \
  ${BSPDIR}/meta-openembedded/meta-webserver \
  ${BSPDIR}/meta-freescale \
  ${BSPDIR}/meta-freescale-3rdparty \
"

Apparently the assigned priority for layers is only considered for
*.bb/*.bbappend files and does not have any effect for conf files.

Placing my layer at the first layer causes bitbake to pick up it's
config in very early stage and ignore other machine specific files.


As I wasn't sure whether other config files are dependent on MACHINE
value and applying any configuration based on machine type
colibri-imx6, I decided to keep "colibri-imx6" the same for now.


Bests,
Isaac
