Designing Embedded Systems with Yocto Online

• 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.

The Live ONLINE training is delivered in 6 hour sessions each day. This includes live tuition and class interaction with the Doulos subject matter expert during the full scope of each session. 

Labs are incorporated within the 6 hour sessions with the Doulos lab platform providing individual (private) tutor support at all times for each delegate. On occasion, labs may require time outside of the 6 hour session to complete. Additional lab material is available in some subjects for individuals to reinforce their understanding of the course content.

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.

Doulos course materials are renowned for being the most comprehensive and user friendly available. Their unique style, content and coverage has made them sought after resources in their own right. The materials include fully indexed class notes creating a complete reference manual.
