One of the greatest challenges facing development teams today is preventing and managing their software bugs. On average, development teams spent at least 40% of their time debugging! For an average development project (1 year), that’s 4.8 months! There are many techniques that developers can follow to dramatically decrease their debug efforts which can result in decreased development costs, faster times to market, a less stressful work environment and more time to focus on product differentiation and features. In this course, attendees will learn the strategies necessary to minimize, prevent and manage software defects while also learning how to quickly and efficiently troubleshoot their systems when bugs do squeak through. Each attendee will assess their own defect management capabilities and will develop an action plan to follow that will improve their skills.

Attendees will also get a hands-on approach as we examine microcontroller hardware and interfaces such as SWD, ITM and the ETM. We will examine traditional debugging techniques such as printf and assertions in addition to examining cutting edge real-time techniques such as OS aware debugging, tracing and deep insight analysis.

The techniques used in this course can be applied to nearly any embedded system and hardware setup.

The course consists of the following sessions:

Session 1 – Managing Defects
Session 2 – Modern Debugging Techniques and Interfaces
Session 3 – Understanding Basic Debugging Techniques
Session 4 – Employing the ITM
Session 5 – The Serial Wire Viewer
Session 6 – Data Tracing, Profiling and Deep Insight Analysis
Session 7 – Using Trace to Understand your Application

The course is taught in a convenient, hands-on style that provides developers with ample time to not just absorb the material but begin to apply it. The course is offered in several different formats that can be found below:

Who Should Attend?

Attendees are engineers and engineering managers who are interested in getting a handle on the amount of time spent debugging their microcontroller based embedded systems. Attendees should understand the fundamentals of the C programming language. Advanced concepts are reviewed as they apply.

Key Take-a-ways:

  • How to strategically evaluate a developer/team’s debugging capability and how to generate an action plan to decrease debug time.
  • The tactics experts employ to minimize the time spent debugging embedded software
  • The modern interfaces, tools and software that can be used to debug a system
  • The different techniques that can be used to debug an embedded system
  • How to setup and use the ITM
  • How to monitor memory and data in real-time with minimal overhead
  • Techniques for tracing application code to find problems quickly
  • How to identify and resolve common RTOS application issues
  • Example code and test hardware platform
  • Best practices for managing and preventing application defects

Hardware and Software:

This course is designed to allow developers dramatically decrease the time they spend debugging. While there will be a focus on the development strategies to follow to accomplish this, each session will accompany a hands-on tactical example to accomplish the strategy. The examples in this course are designed to be usable with any RTOS and platform. Developers can easily use any hardware of their choosing, however, all the examples in the course will use the following hardware and software:

  • FreeRTOS
  • ARM Cortex-M Processor
