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