Valley Island (Bay Trail) BSP is supported by Intel Common Core BSP.

Building Common Core BSP layer for Valley Island (Bay Trail):
===============================================
Please download the Poky build system to your development machine.
$ git clone -b rocko git://git.yoctoproject.org/poky.git

Get the BSP layer either by cloning with Git or downloading the BSP tarball.

Option 1: git clone git://git.yoctoproject.org/meta-intel -b 8.1-rocko-2.4.2

Option 2: Download the corresponding BSP tarball from this ‘Board Support Package (BSP) Downloads’ page of the Yocto Project website.

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 “source” command.
$ source ../poky/oe-init-build-env .

Build an image for Valley Island by adding the location of meta-intel layer to conf/bblayers.conf, e.g.:
BBLAYERS ?= ” \
/path/poky/meta \
/path/poky/meta-poky \
/path/poky/meta-yocto-bsp \
/path/meta-intel \
”

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

To build 32-bit image, add “intel-core2-32” MACHINE to local.conf:
MACHINE = “intel-core2-32”

To build image with specified kernel version of linux-intel (Eg. linux-intel 4.14), add these parameters to local.conf:
PREFERRED_PROVIDER_virtual/kernel = “linux-intel”
PREFERRED_VERSION_linux-intel = “4.14%”

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:
LICENSE_FLAGS_WHITELIST = “commercial”

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-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-vaapi”

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”

Once the configurations are added, kick start the image building process by using bitbake command.
To build an image with sato graphical interface :
$ 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:
core-image-sato-intel-corei7-64.hddimg
OR
core-image-sato-sdk-intel-corei7-64.hddimg

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
example:
# 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.
