Building Mender Yocto Image: Error adding Raspberry Pi layer.

[Luke]

I'm following the docs: https://docs.mender.io/1.3/artifacts/building-mender-yocto-image

Having executed the commands below....

sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \

     build-essential chrpath socat cpio python python3 python3-pip python3-pexpect \

     xz-utils debianutils iputils-ping libsdl1.2-dev xterm

git clone -b rocko git://git.yoctoproject.org/poky

cd poky

git clone -b rocko git://github.com/mendersoftware/meta-mender

source oe-init-build-env

bitbake-layers add-layer ../meta-mender/meta-mender-core

bitbake-layers add-layer ../meta-mender/meta-mender-demo

bitbake-layers add-layer ../meta-mender/meta-mender-raspberrypi

I get this error....

NOTE: Starting bitbake server...

Loading cache...done.

Loaded 1302 entries from dependency cache.

Parsing recipes...done.

Parsing of 840 .bb files complete (838 cached, 2 parsed). 1305 targets, 44 skipped, 0 masked, 0 errors.

Summary: There was 1 ERROR message shown, returning a non-zero exit code.

ERROR: Parse failure with the specified layer added

I've no idea where to start looking to fix this.  Any help appreciated.

Thanks,

Luke.

Hi, 

did you forget to include meta-raspberrypi? 

please take a look at the instructions here: https://github.com/mendersoftware/meta-mender/tree/rocko/meta-mender-raspberrypi

Thanks,

Greg

Thank you Greg. 

I think you're right, I've probably not included the dependency.....and am not sure how I would!

Perhaps the installation of the dependency could be include in the documentation. 

So far all I've done is copy/paste this:

You need to do:

git clone -b rocko https://github.com/agherzan/meta-raspberrypi.git

Additional docs on raspberrypi integration can be found here:

Thanks Mirza, but I'm still not getting all the way through the process.

sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \

     build-essential chrpath socat cpio python python3 python3-pip python3-pexpect \

     xz-utils debianutils iputils-ping libsdl1.2-dev xterm

git clone -b rocko git://git.yoctoproject.org/poky

cd poky

git clone -b rocko git://github.com/mendersoftware/meta-mender

git clone -b rocko https://github.com/agherzan/meta-raspberrypi.git 

source oe-init-build-env

Then change my local.conf to:

MENDER_ARTIFACT_NAME = "release-1"

INHERIT += "mender-full"

MACHINE = "raspberrypi3"

RPI_USE_U_BOOT = "1"

MENDER_PARTITION_ALIGNMENT_KB = "4096"

MENDER_BOOT_PART_SIZE_MB = "40"

IMAGE_INSTALL_append = " kernel-image kernel-devicetree"

IMAGE_FSTYPES_remove += " rpi-sdimg"

DISTRO_FEATURES_append = " systemd"

VIRTUAL-RUNTIME_init_manager = "systemd"

DISTRO_FEATURES_BACKFILL_CONSIDERED = "sysvinit"

VIRTUAL-RUNTIME_initscripts = ""

IMAGE_FSTYPES = "ext4"

and run....

bitbake-layers add-layer ../meta-mender/meta-mender-core

bitbake-layers add-layer ../meta-mender/meta-mender-demo

bitbake-layers add-layer ../meta-mender/meta-mender-raspberrypi

ERROR:  OE-core's config sanity checker detected a potential misconfiguration.

    Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).

    Following is the list of potential problems / advisories:

    MACHINE=raspberrypi3 is invalid. Please set a valid MACHINE in your local.conf, environment or other configuration file.

Did you not add "meta-raspberrypi" to your layers.conf?

You only listed:

bitbake-layers add-layer ../meta-mender/meta-mender-core

bitbake-layers add-layer ../meta-mender/meta-mender-demo

bitbake-layers add-layer ../meta-mender/meta-mender-raspberrypi

Thanks,

Greg

Hi Greg, 

I thought I had by including the command provided by Mirza...

   git clone -b rocko https://github.com/agherzan/meta-raspberrypi.git

...is that not it.

Thanks,

Luke.

Above only clones the git repository.

You must also add it to the bblayers, otherwise bitbake wont parse it.
That is you must run:

bitbake-layers add-layer ../meta-raspberrypi

This is really Yocto basics that you should read about more in the
Yocto mega manual:
