Course Description

The VxWorks® Application Debugging Use Cases course provides development and test engineers with a solid foundation in the use of Wind River® Workbench debugging tools in a variety of situations.

Course Results

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

  • Identify when VxWorks has generated an exception
  • Use the information VxWorks produces as a result of an exception to identify the location and instruction that caused the exception
  • Identify a deadlock condition using System Viewer
  • Use VxWorks facilities to identify the location of a race condition
  • Identify the location and cause of a buffer or stack overflow
  • Use System Viewer to track down the cause of a bug in an interrupt service routine
  • Use the System Mode debug feature in Workbench to trace a problem ISR and fix the bug
  • Use System Viewer to debug a problem that causes a warm boot of VxWorks
  • Add data logging code to an application to be used in conjunction with the System Viewer debugging tool.

Products Supported

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

Who Should Attend

  • Application developers and test engineers faced with diagnosing the cause of an exception
  • Application developers and test engineers needing a way to identify and correct deadlock conditions in VxWorks
  • Engineers, application developers, and test engineers needing a method to diagnose the causes of warm-start events in VxWorks
  • Engineers needing information on how to debug an ISR using Workbench tools
  • Application developers requiring highly customized System Viewer data collection schemes

Course Format

  • One-day set of hands-on use cases covering six 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

Debugging an Application Generating an Exception

  • Understand how VxWorks reports exceptions
  • Interpret the exception message and use it effectively in debugging

Discovering and Fixing a Deadlock Condition

  • Use System Viewer to identify and locate the cause of a deadlock condition
  • Identify the resources involved in a deadlock without seeing the source code
  • Fix the deadlock condition

Debugging a Memory Scribbler

  • Use an exception message to identify a race condition
  • Use the exception message to locate the problem instruction
  • Examine the source code associated with the race condition and provide a fix

Debugging an Interrupt Service Routine

  • Build and boot a defective application
  • Identify the location and context under which the defect manifests
  • Perform system-mode debugging to determine where the algorithm can be modified to eliminate the problem

Using System Viewer in Postmortem Mode to Detect an MMU Violation

  • Configure a VxWorks image to set aside memory not to be initialized on a warm start
  • Configure System Viewer to acknowledge and place data into the configured memory
  • Examine the System Viewer log obtained from the configured memory and determine the location of the offending instruction

Using System Viewer Programmatically

  • Configure and build a VxWorks image that supports System Viewer data collection utilities
  • Write a custom application that makes use of System Viewer instrumentation
  • Run the application to collect and upload data for examination

Prerequisites
