Intended audience
Architect or engineer needing to port Linux to new hardware or extend an embedded system.
Prerequisites
Programming skills. Knowledge of Linux (user level).
Practical details
Hands-on work
Practical work is carried out on Linux servers and Raspberry Pi 4 boards, which you will be able to take away with you after the course.
Course schedule
1 Creating an embedded Linux system
- Embedded Linux environment: concepts, components, generation tools, Buildroot and Yocto Project.
- Standard image production: working environment, Poky, configuration, specific layers, BitBake tool...
- Composition of an embedded Linux system: hardware, bootloader, Linux kernel, init process, boot scripts.
Hands-on work
Installation of Poky and meta-raspberrypi, production of a standard image.
2 On-board system customization
- System discovery and analysis: connection, file systems, standard tree structure, boot.
- Image customization: .bb file, recipe syntax, image recipe creation, users and passwords.
- Adding packages: standard Poky packages, supplied by OpenEmbedded, BusyBox configuration.
Hands-on work
Production of a complete, customized image for Raspberry Pi 4 with packages provided by Poky and meta-openembedded.
3 Advanced system configuration
- Recipe extensions: .bbappend files, recipe file overload, static network configuration.
- Create and apply patches: on a recipe data file, on a source file to be compiled.
- Linux kernel and Device Tree: kernel configuration, kernel patching, Device Tree patching.
Hands-on work
Extensions and patches for base-files, init-ifupdown, nano, BusyBox, kernel...
4 Business code development
- SDK installation: production, extraction and installation of the Yocto SDK.
- Application code compilation: toolchain examination, initialization scripts, cross-compilation of personal code.
- Debugging and fine-tuning: remote debugging with gdbserver, fine-tuning tools (gprof, valgrind, gcov...).
- Integration of business code in the image: recipes, startup launch.
Hands-on work
Writing, debugging and integrating business code into the image.

It would be more interesting to have all the files already in place, so that there are no intentional errors to correct.
