(Embedded) Linux Debugging

title-1
Note

This course can be delivered as an Embedded/Native combo with target boards, or Native Only where target boards are not required.

Course Objectives

The aim of this course is to provide a basic overview of debugging/tracing/profiling facillitites available with (embedded) GNU/Linux. Hands-on exercises provide you with the necessary practical experience to go ahead and choose the right tool for your debugging needs.

Description

This 2-day or 3-day training class uses hands-on exercises combined with instruction to illustrate some basic concepts of debugging/tracing/profiling Embedded GNU/Linux. Hands on sessions are performed with the freely available ELDK, which is derived from Yocto, on a Beagle-XM Rev.C and/or native on Ubuntu. The whole workshop is designed to bring you quickly up to speed. The concepts and commands necessary to make effective use of Embedded GNU/Linux's debugging/tracing/profiling facilties are described through a combination of theory and on-the-job training. Don’t reinvent the wheel, but learn from an experienced trainer and take home a working knowledge of Embedded GNU/Linux debugging and the ability to use it effectively in your own embedded development project.

Prerequisites

  • Basic knowledge of how to use Linux (Ubuntu)
  • Familiarity with embedded C concepts and programming
  • Ability to develop software using C syntax
  • Basic knowledge of embedded processor development boards
  • ... or no fear to learn the aboveand programming

Who should attend?
