Work Tutorials




Introduction to Real-Time Linux

Michael Barabanov

This full day tutorial tackles basic concepts as installation, kernel patching, executables modules, compatibility issues, introduction to the API and designing RT tasks. In detail the tutorial will cover the following fields.

Installation of RTLinux:

  • Installing the base system
  • Patching the kernel for RTLinux
  • Installing the rtlinux executables and kernel modules

Basic concepts:

  • How does RTLinux work
  • The RTLinux API (V3) and compatibility notes
  • A simple kernel module
  • Introduction to the RTLinux API

Modules and Examples:

  • The RTLinux kernel modules
  • How to run the examples - passing parameters
  • Interpretation of the results - how to evaluate a platform
  • Using the debugger and tracer

Designing an RT-Task:

  • How to split the job
  • Outlining the code for a simple driver
  • Introduction to debugging and profiling
  • Interprocess communication


Perfecting Your POSIX Potential

Mario Taschwer

An introduction to programming with the POSIX 1003.c interface using both real time and "normal" Linux. The API will be explored and example code created. The tutorial will show how to create code under user space and then use the same code in a real "real time" environment. Posix scheduler, threads, mutexes, semaphore, conditions etc. will all be covered.



Embedded Real-Time Linux

Nicholas McGuire

A full day tutorial offers a better understanding of system overview, compiling, building a system, kernel modules, passing parameters, platform evaluation and debugging over the network.

Introduction to MiniRTL:

  • MiniRTL system overview
  • Compiling with MiniRTL coplient libs
  • Building a system

Basic concepts:

  • The MiniRTL boot process
  • How does RTLinux work
  • The RTLinux API (V3) and compatibility notes

Modules and Examples:

  • Booting MiniRTL
  • The RTLinux kernel modules
  • how to run the examples - passing parameters
  • Interpretation of the results - how to evaluate a platform
  • Using the debugger over the network

Designing an Embedded RTLinux System:

  • Outlining the code for a simple driver
  • Integrating the driver into the MiniRTL system
  • Communication between MiniRTL and Desk-top Computers


Writing RTLinux Device Drivers

Peter Wurmsdobler, Thomas Leibner

Topics covered are: driver definitions, driver structure, using kernel facilities, boot process, passing arguments at module initialization, using interprocess communication as well as a Data Acquisition Driver design line-by-line.

What is a driver:
  • Outlining the structure of a RTLinux driver
  • Using Linux kernel facilities
  • Communicating with the non-RT task.
Basic concepts:
  • The MiniRTL boot process
  • How does RTLinux work
  • The RTLinux API (V3) and compatibility notes
Kernel Modules:
  • What do the RTLinux Modules provide
  • Passing arguments at module initialization and the proc interface
  • Using Interprocess communication facilities (SHM,FIFO's,signals)
A Data-acquisition driver line by line:
  • Init_module
  • The driver "library"-module
  • Accessing the driver functions
  • Cleanup_module
