Linux is a great OS for embedded devices. Good knowledge of linux layers from the kernel to the user application is a key to the success of the final product. Porting linux to a custom board can also be a complex task depends on the differences between the evaluation board and the custom board.

This course goes deep inside the development process of an Embedded linux system covers many practical tasks in user space and kernel space. It covers how to port linux to a custom board, how to use linux effectively and some patterns and good practices



On Completion, Delegates will be able to

Building BSP (board support package)

Advanced topics in user space programming

Linux network subsystem

Hard real-time in linux

Practices and patterns


Who Should Attend

Embedded Linux developers and software engineers who wants to write more effective code in user and kernel space
