=='''What is the Yocto Project™'''==
The Yocto Project™ is an open source collaboration project that provides templates, tools and methods to help you create custom Linux-based systems for embedded products regardless of the hardware architecture.
Taken directly from the Yocto Project website:
'''Yocto Project™ it's not an embedded Linux distribution – it creates a custom one for you'''
The Yocto Project™ is an umbrella project covering a fairly wide swath of embedded Linux technologies an distributions. For example, the [http://www.angstrom-distribution.org/ Angstrom Distribution ] is declared as a [https://www.yoctoproject.org/organization/angstrom-distribution Yocto Project Participant]

Also target image should be built correctly.   ==='''What is Yocto Project SDK'''===Yocto Project offers a set of tools for developers to create applications (that will run in Yocto created Linux Distributions ) from powerful Host machines. This is also called cross compiling. Yocto Project SDK allows developers to cross compile, debug, and test applications. In fact Yocto Project SDK provides: <div class="itemizedlist">* <span class="emphasis">''Cross-Development Toolchain''</span>: This toolchain contains a compiler, debugger, and various miscellaneous tools.* <span class="emphasis">''Libraries, Headers, and Symbols''</span>: The libraries, headers, and symbols are specific to the image (i.e. they match the image).* <span class="emphasis">''Environment Setup Script''</span>: This <code class="filename">*.sh</code> file, once run, sets up the cross-development environment by defining variables and preparing for SDK use. The SDK is installed on any machine and can be used to develop applications, images, and kernels. An SDK can even be used by a QA Engineer or Release Engineer. The fundamental concept is that the machine that has the SDK installed does not have to be associated with the machine that has the Yocto Project installed. [[CategoryFile:Software_distributionssdk-environment.png|Yoctocenter|869x429px|border]] A developer can independently compile and test an object on their machine and then, when the object is ready for integration into an image, they can simply make it available to the machine that has the Yocto Project. Once the object is available, the image can be rebuilt using the Yocto Project to produce the modified image.   ==='''Why use Yocto Project SDK'''===</div>Normally Target systems specifications are quite restricted, specifically in embedded target systems. It is convenient for the developer, in order to save time, to develop, compile and test their applications on their host platform which is usually a powerful machine. This is the basic of the cross compiling process. Later an emulator is used to test the application.   ==='''How to build ISEE Yocto Project SDK'''===Developers can build ISEE Yocto Project SDK in order to use it at their convenience. First of all a SDK installed will be produced and then developers will user the SDK installer in their Host machines to install all ISEE Yocto Project SDK components. To produce the SDK installer run this command after sourcing Yocto environment (source oe-init-build-env).  bitbake -c populate_sdk igep-image-nameIt is also posible to build an extensible SDK with  bitbake -c populate_sdk_ext igep-image-nameThe resulting SDK installer script can be found in yocto project build folder ./tmp/deploy/sdk/*.sh ==='''How to use ISEE Yocto Project SDK'''===In order to use the ISEE Yocto Project SDK first of all the Installer script must be run in the Host machine where it is intended to develop the software:  ./isee-release-no-x11-glibc-x86_64-igep-basic-image-cortexa9hf-neon-toolchain-2.3.3.shOnce it is installed the environment must be set up with the source script in  After the environment is set up developers can already compile and debug aplications. It can also be used qemu emulator available in  folder to emulate target applications.
