Welcome to the Application Development Toolkit User’s Guide. This manual provides

Project.

The Yocto Project presents the kernel as a fully patched, history-clean git
|
Fundamentally, the ADT consists of an architecture-specific cross-toolchain and
|
||||||
repository.
|
a matching sysroot that are both built by the Poky build system.
|
||||||
The git tree represents the selected features, board support,
|
The toolchain and sysroot are based on a metadata configuration and extensions,
|
||||||
and configurations extensively tested by Yocto Project.
|
which allows you to cross develop for the target on the host machine.
|
||||||
The Yocto Project kernel allows the end user to leverage community
|
|
||||||
best practices to seamlessly manage the development, build and debug cycles.

This manual describes the Yocto Project kernel by providing information

Additionally, to provide an effective development platform, the Yocto Project

on its history, organization, benefits, and use.
|
makes available and suggests other tools as part of the ADT.
|
||||||
The manual consists of two sections:
|
These other tools include the Eclipse IDE Yocto Plug-in, an emulator (QEMU),
|
||||||
<itemizedlist>
|
and various user-space tools that greatly enhance your development experience.
|
||||||
<listitem><para>Concepts - Describes concepts behind the kernel.

You will understand how the kernel is organized and why it is organized in
|
|

the way it is. You will understand the benefits of the kernel's organization
|
|
||||||
and the mechanisms used to work with the kernel and how to apply it in your
|
|
||||||
design process.</para></listitem>
|
|
||||||
<listitem><para>Using the Kernel - Describes best practices and "how-to" information
|
|
||||||
that lets you put the kernel to practical use. Some examples are "How to Build a
|
|
||||||
Project Specific Tree", "How to Examine Changes in a Branch", and "Saving Kernel
|
|

Modifications."</para></listitem>

<title>The Cross-Toolchain</title>

You can find more information on Yocto Project by visiting the website at

<para>

||||||
<ulink url='http://www.yoctoproject.org'></ulink>.
|
The cross-toolchain consists of a cross-compiler, cross-linker, and cross-debugger
|
||||||
|
that are all generated through a Poky build that is based on your metadata
|
||||||
|
configuration or extension for your targeted device.
|
||||||
|
The cross-toolchain works with a matching target sysroot.

<title>Sysroot</title>
|

|
<para>
|
||||||
|
The matching target sysroot contains needed headers and libraries for generating
|
||||||
|
binaries that run on the target architecture.
|
||||||
|
The sysroot is based on the target root filesystem image that is built by
|
||||||
|
Poky and uses the same metadata configuration used to build the cross-toolchain.

The QEMU emulator allows you to simulate your hardware while running your

application or image.
|

QEMU is installed several ways: as part of the Poky tree, ADT installation
|
||||||
|
through a toolchain tarball, or through the ADT Installer.
