Release Notes

Saddle Brook (Skylake) BSP is supported by Intel Common Core BSP.

Building Common Core BSP layer for Skylake-Saddle Brook:
Please download the Poky build system to your development machine.
$ git clone -b krogoth git://git.yoctoproject.org/poky.git

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

Extract the downloaded BSP tarball into meta-intel folder
$ tar -xvjf intel-corei7-64-5.0-krogoth-2.1.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 intel-corei7-64-5.0-krogoth-2.1 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 Saddle Brook 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, they are dependent on gstreamer plugins and ffmpeg plugins.
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:

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 64-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”

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
# sync
# eject /dev/sdf

This should give you a bootable USB flash device. Insert the device
into a bootable USB socket on the Saddle Brook 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.

Note: All prebuilt binaries utilize a time-limited kernel. Yocto Project users should build their own kernel image in their end product.
