Standard Level - 4 days
The Yocto Project is ideal for rapid prototyping and provides the tools and processes required to develop an embedded Linux-based product. The collaboration has widespread support from leading hardware manufacturers, open-source operating systems vendors, and electronics companies looking to address the challenges of developing embedded technology.
This course from Doulos Embedded has been designed to help you understand how to use the Yocto Project tools to manage key components of a Linux distribution: Toolchains, bootloaders, kernels and package management systems. You will learn how to use a Yocto Project based toolchain and tools to develop, debug and test your software, as well as how to use Yocto to customize and maintain an Embedded Linux distribution for multiple boards.
- Engineers who are migrating to a Yocto Project based distribution environment
- Project managers and engineers who are evaluating the use of Linux for their projects
- Project managers and engineers who are considering supporting their own Linux distribution and tools
- Engineers responsible for build systems and software releases
Project managers: This course is designed for those looking to maximise their effectiveness in utilising Yocto to complete embedded systems projects on time and in budget. New Linux projects and projects which will require a long term maintenance cycle would benefit from investigating the components of the Yocto Project. The Yocto Project infrastructure is suitable for Linux projects of any size. Starting from a minimal Linux system, it can be scaled up by integrating additional software in a managed environment.
Engineers: This course outlines how development teams can directly benefit from the tools and SDKs produced by the build system. It clearly separates development cycle tasks from the tasks required to integrate, maintain and distribute software.
Delegates must have attended Developing with Embedded Linux or an equivalent course, or have some experience of using Linux for Embedded Systems. Please contact Doulos to discuss and assess your specific experience against the pre-requisites.
