Voltage domains of the DSTREAM probe
The DSTREAM probe supports two separate voltage domains to work with debug and trace interfaces on
differing voltage rails.
Voltage domain A is used by the following connectors:
•
ARM JTAG 20.
•
TI JTAG 14.
•
ARM JTAG 14.
•
CoreSight 10.
•
CoreSight 20.
•
MIPI 34.
Voltage domain B is used by the following connectors:
•
Mictor 38.
•
MIPI 34.
The MIPI 34 connector is the only one which supports both voltage domains, and is equipped with two
VTREF pins to achieve the correct logic levels.
The VTREF A and VTREF B LEDs on the probe indicate when targets have been detected in the
respective voltage domains.
