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. It connects to the target using hardware interfaces such as
JTAG or Serial Wire Debug (SWD).
DSTREAM 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.

TRC CLK
If green, the TRC CLK LED indicates that a valid trace clock is detected. If red, the TRC CLK
LED indicates that there is a problem with the trace clock.
If the probe TRC CLK LED is green and the DSTREAM unit TRC CLK LED is red then the
target is outputting a trace clock but the DSTREAM unit is unable to lock on to it. Possible
causes for this are that the clock frequency is too high or that the clock frequency is varying too
much.
Note
The DSTREAM unit contains an internal cooling fan that operates to control the internal temperature
when necessary. Do not obscure the ventilation panels on the front and back of the DSTREAM unit.

1.5 The DSTREAM probe
The DSTREAM probe unit allows DSTREAM to interface with commonly-used debug and trace
interfaces provided on a target.
The probe connects to the main DSTREAM unit by a 100mm high-density ribbon cable. An optional 2m
cable is available. When connecting to the target, select the appropriate connectors on the probe to match
the connectors on the target. Cables for each of these connectors are supplied with DSTREAM. At any
one time, use only the cables that are to be connected to the probe unit for the current debug and trace
session.
1.5.1 DSTREAM probe connectors
Various connectors are available on the DSTREAM probe to enable you to connect to the corresponding
connector on your target hardware.
The available connectors for the DSTREAM probe are:
Arm JTAG 14
This is an older Arm connector standard which is now rarely used.
TI JTAG 14
This is a Texas Instruments connector standard used by most TI-based target boards.
Arm JTAG 20
This is the most commonly-used debug connector standard for Arm architecture-based target
boards.
MICTOR 38
This is the most commonly used trace connector standard for Arm architecture-based target
boards. It can also incorporate all the debug signals if they use the same voltage domain.
MIPI 34
This is a MIPI connector standard that supports debug and trace signals. It has two VTref
signals, allowing debug and trace signals to use different voltage domains.
CORESIGHT 10/20
These are high-density connectors that support the 10-way and 20-way CoreSight standards in
addition to a subset of the MIPI debug connection standards.
The following figure shows the layout of the DSTREAM probe connectors:

1.8 The DSTREAM host software
The DSTREAM host software provides the interface between your debugger and the DSTREAM
hardware that controls the target devices.
It translates debugger commands, such as start, stop, and download, into control sequences for a
particular processor. The debug software provides support for debugging on a wide range of Arm
processors. To see a list of supported processors, open the installed Update utility, connect to your debug
hardware, and expand the Templates tree and sub-trees. A list of templates for all supported processors
is displayed.
The DSTREAM software:
• Can address each target device individually, without affecting other devices on the board. It uses this
ability to create virtual connections for each of the JTAG devices on the board. Your debugger can
attach to one of these virtual connections, and perform debugging operations with no knowledge of
the other devices on the board.
• Enables multiple concurrent connections. You can debug or control multicore systems from a single
client debugger, or you can debug or control distinct devices in the system from separate client
debuggers. Depending on the system, the software can also perform a synchronized start or stop of
processors, for debugging multiprocessor systems where the processors interact with each other. For
more information on the capabilities of multicore debug and synchronization, see the DS-5 Debugger
documentation.
• Supports connections across a network, so that you can run the debugging software on several
different computers.
The DSTREAM hardware and software supports multiple concurrent connections from single or multiple
clients.
