What do you want to do?

The ETM Function Trace window is available from the C-SPY driver menu during a debug session.

This window displays a subset of the trace data displayed in the ETM Trace window. Instead of displaying all rows, the ETM Function Trace window shows:

  • The functions called or returned to, instead of the traced instruction

  • The corresponding trace data.

Requirements

One of these alternatives:

  • The C-SPY Simulator. (Not available for all cores and devices.)

  • An I-jet or I-jet Trace in-circuit debugging probe

  • A J-Link/J-Trace JTAG/SWD probe

  • An ST-LINK JTAG/SWD probe

  • A TI XDS probe

Display area

There are two sets of columns available, and which set is used in your debugging system depends on the debug probe and which trace sources that are available:

  • For some combinations of debug probe and trace sources, the available columns are the same as in the ETM Trace window, see Trace window.

  • For the simulator, I-jet Trace, and I-jet and depending on the trace source, these columns are available:

Timestamp

The number of cycles elapsed to this point according to the timestamp in the debug probe.

Address

The address of the executed instruction.

Call/Return

The function that was called or returned to.
