Course Summary:
This 4-day technical training course provides advanced training in the Linux Operating System and the development of Embedded Linux Board Support Packages (BSPs), Device Drivers and Distributions. The first part of the course focuses on advanced applications development in an Embedded Linux context with a focus on application performance measurement and improvement. The latter part of the course covers Linux BSP and Device Driver development including detailed Memory Management approaches for embedded systems and deployment considerations for embedded Linux applications software.
Who Should Attend
The course is designed for real-time engineers who are developing advanced networked Linux applications, BSPs, and Device Drivers for Embedded Linux distributions. It is also targeted at experienced developers requiring a refresher course on Linux BSP and Device Driver development.
Course Objectives
- To gain an understanding of advanced Embedded Linux applications development.
- To provide an overview of Linux application performance measurement and improvement.
- To provide a basic understanding of the Linux I/O Subsystem and the Device Driver Models provided with Embedded Linux distributions.
- To gain an understanding of the complexities of BSP and Device Driver development and their uses in Embedded Linux systems.
- To give students the confidence to apply these concepts to their next Embedded Linux project.
