About this course

You will understand how the VxWorks exception mechanism helps you to diagnose the cause of application software faults. You will also learn how to catch exceptions from the kernel and RTPs so that the target will recover from them within your application code. The Error Detection and Reporting (ED&R) mechanism lets you understand the cause and status of target exceptions. Further, you will learn about hardware interrupts by exploring the watchdog timer API. You will discover how the VxWorks work queue minimises kernel latency, and you can best write your interrupt service routines to take account of it. The labs will let you practically explore exceptions and the ED&R system.
