Create a Yocto* Image with OpenVINO™ toolkit

This document provides instructions for creating a Yocto* image with OpenVINO™ toolkit.

Instructions were validated and tested for Yocto OpenVINO 2020.3 release.

System Requirements

Use the Yocto Project* official documentation to set up and configure your host machine to be compatible with BitBake*.

Setup

Set up Git repositories

The following Git repositories are required to build a Yocto image:

Clone these Git repositories to your host machine:

git clone https://git.yoctoproject.org/git/poky
git clone https://git.yoctoproject.org/git/meta-intel
git clone https://git.openembedded.org/meta-openembedded
git clone https://github.com/kraj/meta-clang.git

Set up BitBake* Layers

source poky/oe-init-build-env
bitbake-layers add-layer ../meta-intel
bitbake-layers add-layer ../meta-openembedded/meta-oe
bitbake-layers add-layer ../meta-openembedded/meta-python
bitbake-layers add-layer ../meta-clang

Set up BitBake Configurations

Include extra configuration in conf/local.conf in your build directory as required.

# Build with SSE4.2, AVX2 etc. extensions
MACHINE = "intel-skylake-64"
# Enable clDNN GPU plugin when needed.
# This requires meta-clang and meta-oe layers to be included in bblayers.conf
# and is not enabled by default.
PACKAGECONFIG_append_pn-openvino-inference-engine = " opencl"
# Enable building inference engine python API.
# This requires meta-python layer to be included in bblayers.conf.
PACKAGECONFIG_append_pn-openvino-inference-engine = " python3"
# This adds inference engine related libraries in the target image.
CORE_IMAGE_EXTRA_INSTALL_append = " openvino-inference-engine"
# This adds inference engine samples in the target image.
CORE_IMAGE_EXTRA_INSTALL_append = " openvino-inference-engine-samples"
# Include inference engine python API package in the target image.
CORE_IMAGE_EXTRA_INSTALL_append = " openvino-inference-engine-python3"
# This adds inference engine unit tests in the target image.
CORE_IMAGE_EXTRA_INSTALL_append = " openvino-inference-engine-ptest"
# Enable MYRIAD plugin
CORE_IMAGE_EXTRA_INSTALL_append = " openvino-inference-engine-vpu-firmware"
# Include model optimizer in the target image.
CORE_IMAGE_EXTRA_INSTALL_append = " openvino-model-optimizer"

Build a Yocto Image with OpenVINO Packages

Run BitBake to build the minimal image with OpenVINO packages:

bitbake core-image-minimal

Verify the Created Yocto Image with OpenVINO Packages

Verify that OpenVINO packages were built successfully. Run 'oe-pkgdata-util list-pkgs | grep openvino' command.

oe-pkgdata-util list-pkgs | grep openvino

Verify that it returns the list of packages below:

openvino-inference-engine
openvino-inference-engine-dbg
openvino-inference-engine-dev
openvino-inference-engine-ptest
openvino-inference-engine-python3
openvino-inference-engine-samples
openvino-inference-engine-src
openvino-inference-engine-staticdev
openvino-inference-engine-vpu-firmware
openvino-model-optimizer
openvino-model-optimizer-dbg
openvino-model-optimizer-dev
