This section describes the requirements and procedure for setting up the trace system for ARM ETM. See Setting up the trace hardware for XScale for information on setting up the trace system for XScale.

You can:

To trace your target hardware, you must set up a hardware trace system, assembling the following components:

When choosing the target hardware and setting up the trace capture system, you must take care not to exceed the timing specifications of the target ETM signals or of the trace capture hardware. Exceeding the timing specifications results in synchronization and data errors that render the trace useless. More information can be found in the chapter on designing the target in the ARM Multi-Trace Version 1.0 User Guide.

You must decide between the available trace capture systems that you can use to connect the ETM to the debugger. The following trace capture systems are described in this manual and are directly supported by TDT:

The following JTAG interfaces are supported by TDT:

The following sections describe how to set up the trace capture hardware for use with TDT:

See The ARM trace solution for a description of how your hardware interacts to complete the real-time trace solution.
