Open-source cross development tools
- Architecture overview. Overview of an embedded system and of the Linux kernel architecture.
- Cross development tool chain, gcc cross compiler, C libraries, glibc and uClibc, GNU debugger, GNU ELF tools.
- Embedded development tools, QEMU, BUILDROOT, BUSYBOX.
Hands-on work
Installation and practice of Buildroot to build a cross compilation toolchain.
The universal Boot loader: uBoot
- uBoot project overview. A walk through the source code. Supported architectures.
- Basic functionalities. The uImage format for booting uBoot Images.
- Practice on a ARM-9 device with uBoot. Configuration, compilation and installation in a qemu sandbox for testing.
- The uBoot configuration options. uBoot commands and environment.
- Integration of new uBoot commands. Development of a standalone program using uBoot as BIOS.
Hands-on work
You will add a new command to uBoot and test uBoot inside QEMU.
Linux kernel
- Licenses implications on kernel and kernel modules development.
- Kernel development tools, quilt, GDB, GIT, LTT. Kernel configuration tool Kbuild.
- Kernel configuration and compilation. Module development and compilation.
- The Linux boot process. The schedulers, preemption and scheduling.
- The Linux driver framework and standard drivers.
- VFS Essentials callbacks, implementing a quick and dirty driver with open, read and write callbacks.
Hands-on work
How to modify the kernel tree to add a new driver to the kernel tree. Generate a patch formatted for the LKML. Develop a character driver outside of the kernel tree.
Root File system
- Bottom-up approach for the root file system creation.
- Adding users management with busybox.
- Application integration.
- Copying the root file system on a memory technology device.
Hands-on work
Create rootfs from scratch using busybox and test it on a real ARM target. Use buildroot to build new generic applications. Add your own application.
Linux and Real-Time
- History and kernel evolution.
- Linux-RT a realtime evolution.
- Nano kernels and interrupt virtualisation.
- Xenomai applications development.
- Real-time Hypervisors.
Hands-on work
Installation of Xenomai, development of a realtime application with Posix and Native Interface. Benchmark comparing Linux standard applications and Xenomai applications under heavy load.
