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
TI JTAG 14
Arm JTAG 20
MICTOR 38
MIPI 34
CORESIGHT 10/20

This is an older Arm connector standard which is now rarely used.
This is a Texas Instruments connector standard used by most TI-based target boards.
This is the most commonly-used debug connector standard for Arm architecture-based target
boards.
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.
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.
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.
