This book describes how to use the version 1.2 Trace Debug Tools (TDT) extension to the ARM Debugger Suite (ADS) version 1.2, especially the ARM eXtended Debugger (AXD). This book documents only TDT version 1.2. It does not describe the core AXD functionality or any other installed extensions.

The main part of this book describes TDT for the ARM ETM. TDT also supports the use of an XScale target. If you are using TDT with an XScale, some elements of the functionality and user interface are different. Chapter 7 Using TDT with XScale describes these differences.
