This course is perfect for those wanting to develop for or build an Embedded Linux system from scratch or commercial embedded Linux solutions.

In this course,

• we start by looking at the various components of an embedded Linux target, development choices and debugging possibilities;
• we learn to use the most common buildsystems: Buildroot and Yocto.
• we take a more detailed look at the Linux kernel architecture: important issues such as cross compilation and building of the most important components;
• we finish by some more specific subjects of your choice (such as Real Time Linux, QT development, ... ).

• A more in-depth look at the system architecture
  • the kernel
  • file systems
  • processes
  • networking
  • more on Bash
  • text editors and Linux command line utilities
• Development tools
  • GNU make, gas, gcc, ld, gdb
  • bootup process of Linux
  • compiler options
  • remote debugging
  • options, builtins and defaults
  • build hierarchy - structure, scripts and makefiles
  • setting up the cross compiler environment toolchain
  • Busybox, buildroot, openembedded/angstrom, ltib
• Kernel architecture
  • processes and the scheduler
  • interrupts
  • memory management
  • modules, kernel
  • char, block, network
  • how to optimize the kernel for latency
  • how to optimize the boot time
  • real-time Linux
• Host/target relationship
  • cross compilation
  • compiler preparation (exercise)
  • linker preparation - ldscript, crt0
  • building an embedded kernel
  • building the root file system
  • the most important components
  • booting - u-boot, redboot, grub, lilo, other boot loaders
  • a running system
  • upgrading your target
• Additional topics
  • networked targets updating techniques
  • Linux Kernel development overview
  • real-time Linux and Xenomai, performance analysis
  • a deeper look into embedded GTK, QT embedded, WebKit and Enlightenment
  • further study

Classical education with practical exercises. During this course all participants will have the opportunity to build and experiment with an ARM-based Embedded Linux board. After the course, the participants can take the board with them to continue experimenting.

Delivered as a live, interactive training: available in-person or online, or in a hybrid format.

IT Background and general Linux skills. Knowledge of things such as kernel compilation and file system internals are prerequisites. C/C++ programming experience is also required.

Everybody who is responsible for designing and maintaining Embedded Linux.systems
