[http://www.pokylinux.org/about Poky] is an open source platform build tool. It is a complete software development environment for = How to get the creation of Linux devices. It enables you to design, develop, build, debug, and test a complete, modern, software stack using Yocto Linux, the X Window System and GNOME Mobile based application frameworks for both x86 and ARM based platforms. Key features include:distribution =
*Full, fast, cross device filesystem creation with '''It's not an embedded Linux Kernel 2.6.x, GCC, GNU C library, Busybox, networking and much more.*Highly configurable and extendable with full documentation, granular feature control, packaging, and wide machine coverage.*Developer friendly with QEMU device virtulisation, SDK generation, Anjuta IDE, OProfile and GDB integration.*Complete GNOME Mobile platform with the X Window System, Matchbox, GTK+ 2.12, D-Bus, GStreamer and distribution – it creates a custom one for you''Sato' reference implementation.*Support for bleeding edge OpenGL user interfaces with the Clutter toolkit.*A supported, stable and proven base for real world products built on Linux and open source software.

==Why use the Yocto Project™ = Feedback and Contributing ===At any point, if you see a mistake you can contribute to this How-To.
==== How Because it's a complete embedded Linux development environment with tools, metadata, and documentation - everything you need. The free tools are easy to get involved started with, powerful to work with (http://pokylinuxincluding emulation environments, debuggers, an Application Toolkit Generator, etc.org/support/) ====and they allow projects to be carried forward over time without causing you to lose optimizations and investments made during the project’s prototype phase. The Yocto Project fosters community adoption of this open source technology allowing its users to focus on their specific product features and development
There are many ways to get involved with the Poky project. Poky has a friendly community providing informal support and discussion.== Build Platform Setup Environment ==
'''Mailing list'''In order to build an image with BSP support for a given release, you need to download the corresponding BSP repository. At this time latest stable branch for IGEP devices is denzil.
To subscribe send mail to; $ git clone -b denzil git://git.isee.biz/pub/scm/poky.git
Enter to the poky+subscribe <at> openedhand <dot> comdirectory,
And follow simple instructions in subsequent reply. Archives are available here. $ cd poky
'''Bugs'''and clone the meta-isee layer.
Problems with Poky should be reported in the bug tracker: http $ git clone -b denzil git://bugzillagit.isee.obiz/pub/scm/meta-handisee.com/git
'''IRC''' $ source oe-init-build-env
Chat with Having done that, and assuming you downloaded the Poky development team and community in #poky on freenodeBSP contents at the top-level of your yocto build tree, you can build a igep image by adding the location of the 'meta-igep' layer to 'bblayers.conf'

MACHINE ?=== Poky Platform Setup Environment ==="igep00x0"
Poky is derivative of the Open Embedded. In order You should then be able to function properly, the Virtual Machine need some adaptations of the development system.build a image as such:
The first thing we need to do is set Bash as default sh shell, execute<pre> $ sudo dpkgbitbake demo-reconfigure dash</pre>and answer no when asked whether you want to install dash as /bin/sh. So, now, "/bin/sh" file links to "/bin/bash" (not to "/bin/dash").image-sato
An other change we need to perform is to change some default settings At the end of the kernel. Edit the /etc/sysctl.conf file as root with your preferred editor and set the vm.mmpap_min_addr to 0<pre>$ sudo nano /etc/sysctl.confvm.mmap_min_addr = 0</pre>thena successful build, run this command<pre>$ sudo sysctl you should have an image that you could use for boot device from flash or a micro-p</pre>SD card.
Install extra == Extending the available packages necessary for bitbake to function.<pre>$ sudo apt-get update$ sudo aptitude install subversion cvs git-core \ build-essential help2man diffstat texi2html texinfo \ libncurses5-dev gawk python-dev python-psyco python-pysqlite2 \ scrollkeeper gnome-doc-utils gettext automake mercurial libx11-dev \ libgl1-mesa-dev libglu1-mesa-dev libsdl1.2-dev</pre>with others layers ==
==== Poky version 3.2 codename Purple (stable branch) ====Poky version 3.2 ( stable branch) is available from a GIT repository located at git://git.igep.es/pub/scm/poky.git. The first thing You can append more layers to your environment in order to build more packages, in following wxample you will do is clone 'll download the Poky projectmeta-openembedded layer.In your poky directory

At this point Add the Poky layer into build environment needs to be set up, you will do this with the poky-init-build-env script. Sourcing this file in a shell makes changes to PATH and sets other core bitbake variables based on the current working directory/conf/bblayers.conf:
Refer <path to http:>/poky/www.pokylinux.orgmeta-openembedded/doc/poky-handbook.html#refmeta-images for standard imagesoe \
Refer to [[Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine]] to how to install and use poky images on a NFS-mounted root filesystem.Now you can build any of the new packages added, for example:
==== Poky version 3.3 codename Green (under development) ==== $ bitbake postgresql
[http://www.pokylinux.org/releases/green-3.3/doc/poky-handbook.html The Poky handbook guides] users through getting started with Poky and explains how the build system components fit together and interact. The setup and use of the SDK is also covered along with other common development tasks such as debugging and profiling applications. It also contains extensive reference material on many other aspects of Poky such as the classes, variables and other technical details.== Create your own Linux image ==
A customized Poky version 3.3 for IGEP platforms is available from a GIT repository located at git://git.igep.es/pub/scm/poky.git. TODO
The first thing you will do is clone the Poky project== Yocto 1.2 'denzil' documentation ==
