3.9. Viewing information about the target topology

If your development platform supports trace components, then you can view information about the target topology.

Note

This feature is supported only for connections through the RealView ICE Debug Interface, and only when using a DSTREAM unit or a RealView ICE unit with v3.1 firmware or later.

To view the target topology:

  1. Before you can view the topology for your development platform, you must set up the associations for the target processors and other components. To do this:

    1. Create a text file containing the device associations for your development platform.

    2. Open the RVConfig utility for your RealView ICE Debug Configuration.

    3. Assign the associations file to your Debug Interface configuration.

    Example 3.1 shows the associations file entries for the topology shown in Figure 3.15:

    Example 3.1. Trace device associations

    Name=ARMCS-DP;Type=ARMCS-DP;
    Name=Cortex-R4_1;Type=Cortex-R4;ETM=CSETM_1;
    Name=CSETM_1;Type=ETM;TraceOutput0=CSTPIU;TraceOutput1=CSETB;Core=Cortex-R4_1;
    Name=CSETB;Type=ETB;Port0=CSETM_1;
    Name=CSTPIU;Type=TPIU;Port0=CSETM_1;
    

  2. Select Target → Connect to Target... from the Code window main menu to open the Connect to Target window.

  3. Select View → Show NonCores from the menu to display the non-processor devices.

    Note

    Non-processor devices are hidden by default.

  4. Select Configuration from the Grouped By field.

  5. Expand the RealView ICE Debug Interface.

  6. Expand the Debug Configuration for your development platform. An example of a development platform with CoreSight components is shown in Figure 3.15:

  7. Expand the processor node to show the ETM associated with the processor.

  8. Right-click on the component for which you want to view the topology. For the example shown in Figure 3.15, right-click on CSETM_1.

  9. Select Topology from the context menu to open the Topology dialog box. Figure 3.16 shows an example:

    Note

    The Topology menu option is enabled only when the associated Debug Interface configuration has an associated device topology.
