1. Introduction

Welcome to the Yocto Software Development Kit (SDK) Guide. SDK allows developers in quick development and testing during development stage. It eliminates the need of downloading & setting-up of full repository environments.

Setting a full RDK stack is also quite time consuming and requires a high end machine having good disk space and CPU power for the build process. In the other hand SDK supports following features to overcome above challenges.

• A minimal collection of tool chain, development binaries, supporting headers & libraries are shipped in the form of a self extracting script.
• Allows to build any component using generic auto tool or similar build approach.
• Supports packaging so as to install the modified software in target in a easy manner while taking care of the dependencies.

This page provides information that explains how to use both the Yocto SDK to develop images and components using the Yocto Project. A SDK consists of the following:

...

Fundamentally, the SDK fits into the development process as follows:

Image Removed

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. 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.
