Introduction

Dedicated applications are what define an embedded product and Yocto offers helpful application development tools, as well as the functionality to integrate with popular Integrated Development Environments (IDE) such as Eclipse and Qt Creator. It also provides a wide range of utility classes to help in the integration of finished applications into the build system and target images. A normal embedded Linux software development team is logically divided into the following roles:

• BSP developers in charge of the Board Support Package, which is the bootloader and Linux kernel. This team has the greatest exposure to the hardware. As we have seen in Chapter 2, The BSP layer, BSP development uses primarily the Yocto SDK.
• Application developers will work on the Linux user space applications that define the product, including user interfaces. Developing applications for embedded Linux is not that different from developing applications for a Linux server or desktop, as the kernel abstracts...
