1.1 About DSTREAM

DSTREAM is a debug and trace hardware unit that enables powerful software debug and optimization on any ARM processor-based hardware target.

DSTREAM enables you to connect a software debugger to an ARM processor-based target using a hardware interface such as JTAG or Serial Wire Debug (SWD). It also enables the collection of trace from the device for non-intrusive debug and code optimization.

Note

Some debuggers are unable to capture trace from the external trace port of a System-on-Chip (SoC) device. See the documentation that accompanies your debugger for details of the trace capabilities of your debugger.
