3.3.3. Setting the port size

The port size is the maximum data width that can pass from the target to the RealView Trace 2 hardware.

Use the Port Size drop-down menu to specify the port size of the target's ETM. The port size is 16 by default, but can be changed to any of the following values:

Note

Trace implementations with insufficient bandwidth limits may result in ETM buffer overflows when profiling in cycle accurate mode. This is most common in 8 bit or lower trace port widths.
