Course Description

The VxWorks® Intermediate Application Development Use Cases course provides engineers with a solid grounding in a selection of the more sophisticated APIs provided in VxWorks.

Course Results

After this course, participants will be able to perform the following:

  • Effectively use two different signal interfaces to deal with synchronous events
  • Leverage semaphores, message queues, and events to support applications with complex interactions
  • Use three VxWorks-specific printing APIs that provide greater capability and flexibility than printf
  • Use VxWorks APIs to map physical memory to the virtual address space of a real-time process
  • Create and use shared libraries to decrease memory footprint of applications

Products Supported

  • Wind River® VxWorks 6.9
  • Wind River Workbench 3.3
  • Wind River Simics 4.6

Who Should Attend

  • Software developers needing to implement synchronous behavior in an application
  • Engineers needing to provide graceful exception-handling capabilities to application developers
  • Software developers needing to understand how to use VxWorks kernel calls in a complex application
  • Software developers needing a variety of simple debug tools akin to printf but with greater capability
  • Engineers required to provide device driver support within the context of a real-time process
  • Software developers needing to share code between applications running in multiple real-time processes

Course Format

  • One day of hands-on use cases covering five topics, with technical assistance and individual guidance available from an expert instructor
  • Use of VxWorks 6.9, Workbench 3.3, and Simics 4.6 to gain experience with the topics presented

Syllabus

Use Cases

Day 1

Using Signals

  • VxWorks generic and POSIX signal APIs
  • Writing simple handlers
  • Passing parameters
  • Multiplexing signals through a single handler
  • Masking and signal deferral

Inter-task Coordination and Communication

  • Semaphores for synchronization and mutual exclusion
  • Synchronization through the events API
  • Message passing

Instrumenting Code by Printing

  • Advantages of print services
  • Printing at interrupt time
  • Graphical printing
  • Event points and instrumenting dynamically

Accessing Physical Memory from a Real-Time Process

  • BSP modification requirements
  • Mapping physical addresses to the RTP virtual address space
  • Tools and techniques for examining the RTP virtual address space mapping

Using Shared Libraries from a Real-Time Process

  • Creating shared libraries using Workbench
  • Creating file systems to support real-time processes and shared libraries
  • Dynamically linking real-time process code to shared libraries

Prerequisites

Prerequisite Courses

Prerequisite Skills
