This intensive four-day course will teach you the techniques required to build Linux into embedded systems. During the hands-on sessions you will learn about the fundamental elements that underpin all embedded Linux projects: the toolchain, the bootloader, the Linux kernel and the root filesystem. You will create each of these elements from scratch, and discover out how to automate the process using tools such as Buildroot and the Yocto Project. In later sessions you will delve into architectural issues such as file system layout, how to split functions between user and kernel space and real-time programming. You will also find out how to debug and profile code at both the application level and within the kernel so that you will be able to identify bugs and resolve performance bottlenecks.
The theory is backed up with hands-on labs where you will get a chance to try out all the concepts covered in the presentations. At the moment it is only available on-line, using a virtual classroom. You will build a fully-functional system using the QEMU emulator as the target.

This course is ideal for software engineers who are familiar with embedded devices but need to apply that knowledge to Linux development, and to those who are familiar with Linux, but want to apply that knowledge to embedded systems
Essential: good knowledge of the C programming language, since this is used in the programming portions of the course
Desirable: either a good background in embedded devices, or a reasonable proficiency in Linux command-line tools. Delegates with neither will find the learning curve rather steep
All students will receive:
Introduction to Embedded Linux
The bootloader and kernel
Device trees
Root filesystem
File systems and flash memory
Embedded Linux build systems
Init, device management and logging
Understanding Toolchains
Debugging using GDB
Linux device drivers
Profiling and tracing
Real time
