Practical details
Hands-on work
Every step of the training session is immediately applied as a case study on an embedded ARM board with a touch screen to test graphical developments.

Course schedule

1
The cross development tools

  • 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 and Scratchbox

2
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.
  • Configuration, compilation and installation in a QEMU sandbox for testing.
  • Development of a standalone program using uBoot as BIOS.
  • uBoot BSP. Adding a new SOC and a new board in the uBoot BSP tree.
Hands-on work
Add a new command to uBoot and test uBoot inside QEMU, generate a new BSP for uBoot and develop a simple stand alone program using uBoot as BIOS.

3
Linux kernel

  • Licenses implications and kernel modules development. Development cycles.
  • Kernel development tools, quilt, GDB, GIT, LTT. Configuration tool Kbuild.
  • The Linux boot process.
  • Devices drivers. The Linux driver framework and standard drivers.
  • The Linux BSP. Adding a new board to Linux.
  • Specific embedded systems drivers MTD drivers, CAN, SPI and I2C drivers.
Hands-on work
Modify the kernel tree to add a new driver to the kernel tree and generate a patch formatted for the LKML. Develop a character driver outside of the kernel tree.

4
Root File system

  • Creation of a rootfs. A tiny root file system, back to UNIX fundamentals and the init program.
  • Manage users on an embedded system with busybox.
  • Dynamic libraries or static programs. Choosing a root file system architecture.
  • Building a rootfs as CPIO or as EXT2 file system.
  • Creating JFFS2, UBIFS or YAFFS file systems.
Hands-on work
Create rootfs from scratch using busybox and test it on a real ARM target.Use buildroot to add new applications.Add your own application developed using SCRATCHBOX.Test the buildroot generated rootfs.

5
Limits of Linux Embedded

  • Industrial realtime application.
  • Power management.
  • Embedded interfaces.
  • Complete embedded framework.
  • Debugging. Using QEMU to debug and embedded system.
Hands-on work
You will modify the Linux boot-logo using standard Linux graphical tools. Test a hard realtime solution. Debug an application on the ARM target.

Participants also complete a placement test before and after the course to measure the skills they’ve developed.

TEACHING AIDS AND TECHNICAL RESOURCES
• The main teaching aids and instructional methods used in the training are audiovisual aids, documentation and course material, hands-on application exercises and corrected exercises for practical training courses, case studies and coverage of real cases for training seminars.
• At the end of each course or seminar, ORSYS provides participants with a course evaluation questionnaire that is analysed by our instructional teams.
• A check-in sheet for each half-day of attendance is provided at the end of the training, along with a course completion certificate if the trainee attended the entire session.

TERMS AND DEADLINES
Registration must be completed 24 hours before the start of the training.
