ARM DS-5 Using the Debug Hardware Configuration Utilities

Using Trace7.3 Configuring trace lines (DSTREAM and RVT2 only)If you have a DSTREAM unit or RVT2 unit, you can configure delays on the trace lines. To dothis:1. Open the Debug Hardware Config utility.2. If you have already configured a debug hardware unit, select Open from the File menu tolocate and open the corresponding configuration file.Otherwise:a. Connect to the required debug hardware unit.b. Create a new debug hardware configuration.3. Select the Trace node in the tree control. The following figure shows an example:Figure 7-1 Trace node in Debug Hardware ConfigYou can delay each line by a specified amount of time (expressed in picoseconds, in 75psintervals). Default delays are configured into the unit, and you are able to delay eachsignal by a specified amount relative to these defaults, allowing for variations in targethardware.You can also invert the clock so that data is sampled on the falling edge (rather than onthe rising edge) of the clock. To do this, select the True/False checkbox. The default isFalse (unchecked).NoteSome debuggers have limitations when tracing with DSTREAM. See the DS-5 Debuggerdocumentation for details of the trace capabilities.7.3.1 See alsoTasks• Connecting to a debug hardware unit on page 2-8• Creating a debug hardware configuration file on page 5-4• Configuring your debugger for trace capture on page 7-6.ARM DUI 0498F Copyright © 2010-2012 ARM.
