        <title>Welcome!</title>
        <para>
            Welcome to the Yocto Project!
            The Yocto Project is an open-source collaboration project whose
            focus is developers of embedded Linux systems.
            Among other things, the Yocto Project uses a build host based
            on the OpenEmbedded (OE) project, which uses the
            <ulink url='&YOCTO_DOCS_DEV_URL;#bitbake-term'>BitBake</ulink>
            tool, to construct complete Linux images.
            The BitBake and OE components are combined together to form
            a reference build host, historically known as
            <ulink url='&YOCTO_DOCS_DEV_URL;#poky'>Poky</ulink>.
        </para>

        <para>
            If you do not have a system that runs Linux and you want to give
            the Yocto Project a test run, you might consider using the Yocto
            Project Build Appliance.
            The Build Appliance allows you to build and boot a custom embedded
            Linux image with the Yocto Project using a non-Linux development
            system.
            See the
            <ulink url='https://www.yoctoproject.org/tools-resources/projects/build-appliance'>Yocto Project Build Appliance</ulink>
            for more information.
        </para>

        <para>
            This quick start is written so that you can quickly get a host
            build host set up to use the Yocto Project and then build some
            Linux images.
            Rather than go into great detail about the Yocto Project and its
            many capabilities, this quick start provides the minimal
            information you need to try out the Yocto Project using a
            supported Linux build host.
            Reading and using the quick start should result in you having a
            basic understanding of what the Yocto Project is and how to use
            some of its core components.
            You will also have worked through steps to produce two images:
            one suitable for emulation and one that can be used on actual
            hardware.
            The examples highlight the ease with which you can use the
            Yocto Project to create images for multiple types of hardware.

        <title>Introducing the Yocto Project Development Environment</title>

        <para>
            The Yocto Project through the OpenEmbedded build system provides an
            open source development environment targeting the ARM, MIPS,
            PowerPC, and x86 architectures for a variety of platforms
            including x86-64 and emulated ones.
            You can use components from the Yocto Project to design, develop,
            build, debug, simulate, and test the complete software stack using
            Linux, the X Window System, GTK+ frameworks, and Qt frameworks.

        <para>
            Here are some highlights for the Yocto Project:
        </para>

        <itemizedlist>
            <listitem><para>
                Provides a recent Linux kernel along with a set of system
                commands and libraries suitable for the embedded
                environment.

                Makes available system components such as X11, GTK+, Qt,
                Clutter, and SDL (among others) so you can create a rich user
                experience on devices that have display hardware.
                For devices that do not have a display or where you wish to
                use alternative UI frameworks, these components need not be
                installed.
                </para></listitem>
            <listitem><para>
                Creates a focused and stable core compatible with the
                OpenEmbedded project with which you can easily and reliably
                build and develop.
                </para></listitem>
            <listitem><para>
                Fully supports a wide range of hardware and device emulation
                through the Quick EMUlator (QEMU).
                </para></listitem>
            <listitem><para>
                Provides a layer mechanism that allows you to easily extend
                the system, make customizations, and keep them organized.
                </para></listitem>
        </itemizedlist>

        <para>
            You can use the Yocto Project to generate images for many kinds
            of devices.
            As mentioned earlier, the Yocto Project supports creation of
            reference images that you can boot within and emulate using QEMU.
            The standard example machines target QEMU full-system
            emulation for 32-bit and 64-bit variants of x86, ARM, MIPS, and
            PowerPC architectures.
            Beyond emulation, you can use the layer mechanism to extend
            support to just about any platform that Linux can run on and that
            a toolchain can target.
        </para>

        <para>
            Another Yocto Project feature is the Sato reference User
            Interface.
            This optional UI that is based on GTK+ is intended for devices with
            restricted screen sizes and is included as part of the
            OpenEmbedded Core layer so that developers can test parts of the
            software stack.

                versions of the most popular Linux distributions that
                provide stable releases.
                In general, if you have the current release minus one of the
                following distributions, you should have no problems.

            <para>
                The OpenEmbedded build system should be able to run on any

                If your build host does not meet any of these three listed
                version requirements, you can take steps to prepare the
                system so that you can still use the Yocto Project.
                See the

        <section id='packages'>
            <title>The Build Host Packages</title>

            <para>
                Required build host packages vary depending on your
                build machine and what you want to do with the Yocto Project.
                For example, if you want to build an image that can run
                on QEMU in graphical mode (a minimal, basic build
                requirement), then the build host package requirements
                are different than if you want to build an image on a headless
                system or build out the Yocto Project documentation set.
            </para>

            <para>
                Collectively, the number of required packages is large
                if you want to be able to cover all cases.
                <note>
                    In general, you need to have root access and then install
                    the required packages.
                    Thus, the commands in the following section may or may
                    not work depending on whether or not your Linux
                    distribution has <filename>sudo</filename> installed.
                </note>
            </para>

            <para>
                The following list shows the required packages needed to build
                an image that runs on QEMU in graphical mode (e.g. essential

            <para>
                The last requirement you need to meet before using the
                Yocto Project is getting a Yocto Project release.
                It is recommended that you get the latest Yocto Project release
                by setting up (cloning in
                <ulink url='&YOCTO_DOCS_DEV_URL;#git'>Git</ulink> terms) a
                local copy of the <filename>poky</filename> Git repository on
                your build host and then checking out the latest release.
                Doing so allows you to easily update to newer Yocto Project
                releases as well as contribute back to the Yocto Project.
            </para>

            <para>
                Here is an example from an Ubuntu build host that clones the
                <filename>poky</filename> repository and then checks out the
                latest Yocto Project Release (i.e. &DISTRO;):

                <para>
                    By default, the build process searches for source code
                    using a pre-determined order through a set of
                    locations.
                    If you are working behind a firewall and your build
                    host is not set up for proxies, you could encounter
                    problems with the build process when fetching source
                    code (e.g. fetcher failures or Git failures).
                </para>

                <para>
                    If you do not know your proxy settings, consult your
                    local network infrastructure resources and get that
                    information.
                    A good starting point could also be to check your web
                    browser settings.

                    Before using BitBake to start the build, you can
                    look at this file and be sure your general

                    Use the following command to build the minimal image for
                    MinnowBoard MAX.
                    Because configuration changes are minimal to set up for
                    this second build, the OpenEmbedded build system can
                    re-use files from previous builds as much as possible.
                    Re-using files means this second build will be much faster
                    than an initial build.

     $ bitbake core-image-minimal

                    You can write the image to a USB key, SATA drive, or SD
                    card by using the <filename>mkefidisk.sh</filename> script,

                    <replaceable>TARGET_DEVICE</replaceable> is the name of the

                    With the boot device provisioned, you can insert the
                    media into the MinnowBoard MAX and boot the hardware.
                    The board should automatically detect the media and boot to
                    the bootloader and subsequently the operating system.
