Embedded Linux Basics

Course description

The course Embedded Linux Basics is designed to teach developers how to customise and use the Linux operating system for embedded systems. Participants learn by doing - with several practical exercises and examples. The Linux system architecture with the main subsystems and their functionality is described along with the tools needed for development.

Both theory and exercises follow the natural steps of commissioning a new target system: we start with the bootloader, continue with the kernel, and then add a fully functional root file system.

The course is based on over 15 years of experience in Linux for Embedded Systems courses and experience from more than 50 different development projects. We share many of our experiences.

The exercises are normally based on common ARM-based target systems but can, for local customised courses, be adapted to customer-specific target systems.

The course is normally given in Swedish but all course material is in English. The course is given in English on request.
