The 7th Generation Intel® Core Halo Reference Platform BSP is supported by Intel Common Core BSP.

Building Common Core BSP layer for the 7th Generation Intel® Core Halo Reference Platform:
Please download the Poky build system to your development machine.
$ git clone -b pyro git://git.yoctoproject.org/poky.git

Download the corresponding BSP tarball from this ‘Board Support
Package (BSP) Downloads’ page of the Yocto Project website.

Extract the downloaded BSP tarball into meta-intel folder
$ tar -xvjf meta-intel-7.0-pyro-2.3.tar.bz2

Rename the folder of the extracted BSP tarball to meta-intel.
Note: Ignore this step if there is already a folder with the same name.
$ mv meta-intel-7.0-pyro-2.3 meta-intel

Create a build folder at the same level of “poky” directory.
$ mkdir yocto_build
$ cd yocto_build

Assuming that you have downloaded the BSP tarball and extracted the content at top level of your development build tree, you need to
prepare the build environment using the “source” command.
$ source ../poky/oe-init-build-env .

You can build an image for 7th Generation Intel® Core Halo Reference Platform by adding the location
of meta-intel layer to bblayers.conf, e.g.:
/path/poky/meta \
/path/poky/meta-yocto \
/path/poky/meta-yocto-bsp \
/path/meta-intel \

To build a 64-bit image, add “intel-corei7-64” MACHINE to local.conf:
MACHINE = “intel-corei7-64”

Suggested settings for better graphic driver support:

meta-intel contains support for the i915 graphics driver.
However, to have a minimum setup of video components, gstreamer plugins need to be installed.
These gstreamer plugins require license flags in order to be included in the build.
Add “commercial” in the LICENSE_FLAGS_WHITELIST in local.conf. For example:

Note: By adding LICENSE_FLAGS_WHITELIST = “commercial”, it signifies that you understand the legal
requirements imposed by all of those included software ingredients.

To enable full hardware acceleration for video decode support, GStreamer 1.x base
and GStreamer-VAAPI packages need to be included as part of the Yocto Project build output
image. This can be done by adding the meta-intel as part of the bblayers.conf (as mentioned above).
The default GStreamer packages do not come with full codecs support; some additional
plugins need to be added manually in local.conf to support certain playback:
IMAGE_INSTALL_append =+ ” gstreamer1.0-plugins-ugly gstreamer1.0-libav”

For those who required to execute a 32-bit standalone application on Yocto,
the multilib environment need to be turned on in yocto_build/conf/local.conf as the configuration below:

require conf/multilib.conf
DEFAULTTUNE = “corei7-64”
MULTILIBS = “multilib:lib32”
DEFAULTTUNE_virtclass-multilib-lib32 = “corei7-32″

To enable 32-bit libraries into final bootable image, you need to add the following settings in
IMAGE_INSTALL_append = ” lib32-glib-2.0 lib32-gcc”

Once the configurations are added, build an image as such:
$ bitbake core-image-sato

For building an image with the development tools, type the following command:
$ bitbake core-image-sato-sdk

A bootable image will be generated in yocto_build/tmp/deploy/images/intel-corei7-64/ once the
compilation successful.
File name that will be generated:

At the end of a successful build, you should have a live image that can be used to directly
boot Yocto off of a USB flash drive.

Under Linux host machine, insert a USB flash drive. Assuming the USB flash drive
takes device /dev/sdf, use dd to copy the live image to it. For
# dd if=core-image-sato-intel-corei7-64.hddimg of=/dev/sdf bs=4M
# sync
# eject /dev/sdf

This should give you a bootable USB flash device. Insert the device into a bootable USB socket on the
platform, and power on. This should result in a system booted to the Sato graphical desktop. The root
password is empty on the Poky reference distribution images.
