Decoding binary traces with a Dictionary file

To activate and deactivate binary traces that are in the Open System Trace (OST) format, you must first define the used Dictionary file for the component that is outputting the traces. Dictionary files are in XML and are usually available in your development environment. They are automatically re-generated everytime you compile a component that contains OST traces.

You can open a Dictionary file to be used for decoding binary traces, based on a decode model.

To open a Dictionary file:

  1. On the TraceViewer menu, select Trace Activation.
  2. In the Activation dialog, click Add Dictionary.
  3. In the Open file dialog, choose one or more decode files from the file system.

    By default, these files are located in the \epoc32\ost_dictionaries directory, and named [componentname]_uid_dictionary.xml
    Note: You can also load a ZIP file containing one or more Dictionary files.

  4. Click OK.

    TraceViewer will load the chosen files to the decoding model and decode the traces currently in the view.
