This course introduces the open source operating system Linux and its use for building embedded and real-time systems.
We will define embedded computing and see why the GNU/Linux operating system is a major player in this huge market.
Think about embedded software in smartphones, network devices, entertainment, Internet of Things...
We will also look at the internals, key elements, essential knowledge, common processes and development tools to build an embedded system.
The rest of the course is devoted to case studies running Linux on a Raspberry-Pi ARM-based development board.
