Connect and power up the DSTREAM-PT system

Describes how to connect your DSTREAM-PT system to your host PC and target hardware.

Before you begin

  • You must have installed Arm Development Studio to access the software drivers and debug hardware configuration utilities.

  • Your target hardware must have a debug connector supported by DSTREAM-PT. For a list of supported connectors, see Target interface connectors the Arm® DSTREAM-PT System and Interface Design Reference Guide.

  • You must have the following items from the Arm DSTREAM-PT box contents:

    • The DSTREAM-ST unit.

    • The Parallel Trace probe, with the 60-way AUX cable.

    • The power supply unit, dual DC power cable, and the mains cable that is appropriate for your region.

    • To connect the DSTREAM-ST unit to the host PC or the network, you need either: * The USB cable, to connect the DSTREAM-ST unit directly to the host PC using the USB 3.0 port. * The Ethernet cable, to connect the DSTREAM-ST unit to the network.

    • To connect DSTREAM-PT to the target hardware, you need a target-compatible cable. For a list of supplied cables, see Arm DSTREAM-PT box contents.

Warning

  • If DSTREAM-PT or the target hardware are not earthed, potential differences can occur between them. During connection, potential differences cause unwanted pulses in the debug interface. This might also cause unwanted resets to occur.

  • Ensure the target connector has a compatible pinout before use. Incorrect connections might damage the debug or target hardware.

Procedure

  1. Connect the DSTREAM-ST unit, the Parallel Trace probe, and the power supply unit:

    1. Connect the DSTREAM-ST unit and the Parallel Trace probe using the 60-way AUX cable.

    2. Attach the shorter 5V DC input end of the split power supply cable to the DSTREAM-ST unit, and attach the longer 5V DC input end to the Parallel Trace probe.

      Note

      Depending on your device arrangement, the 5V DC inputs are identical and you can attach them to either the DSTREAM-ST unit or the Parallel Trace probe.

    3. Attach the Power Supply Unit (PSU) to the PSU-adapter end of the split power supply cable.

  2. Connect the DSTREAM-ST unit to the host PC:

  3. Power up the DSTREAM-PT system.

    When you power up the DSTREAM-ST unit and Parallel Trace probe, both units follow a boot sequence. The LEDs identify the progress of the boot sequence. For more information, see DSTREAM-PT system boot sequence.

    Note

    Arm recommends that both the DSTREAM-ST unit and Parallel Trace probe are powered-up simultaneously. Powering simultaneously ensures that the DSTREAM-ST unit correctly detects the Parallel Trace probe during its boot sequence.

    If you need to reset the DSTREAM-PT system, press the reset button on the rear of the DSTREAM-ST unit. When a DSTREAM-ST unit is connected in a DSTREAM-PT system, the reset button on the DSTREAM-ST unit re-initializes both the DSTREAM-ST unit and the Parallel Trace probe.

  4. If you are connecting across an Ethernet network, configure the Ethernet and internet protocol settings for your DSTREAM-ST unit. To configure these settings, use the Debug Hardware Configure IP view in Arm Development Studio.

    You can also use the Debug Hardware Configure IP view to assign a name for the DSTREAM-ST unit. For more information, see the Arm Development Studio documentation for Debug Hardware Configure IP view.

  5. Connect the DSTREAM-PT system to the target hardware. Use the appropriate cables and adapters for the target debug and trace connector (or connectors). Some targets have debug and trace on a single connector, and some targets split them between two connectors. Each connector, and the appropriate cable to use for that connector, is described in Target interface connectors in the Arm DSTREAM-PT System and Interface Design Reference Guide.

    Warning

    When connecting the DSTREAM-PT system to target hardware, to avoid damaging the target or debug hardware, ensure that the debug and trace connector (or connectors) on the target use pinouts supported by DSTREAM-PT. For supported pinout information, see the Arm DSTREAM-PT System and Interface Design Reference Guide.

    • If your target has debug and trace on a single connector, connect the Parallel Trace probe to the target using the 60-way MIPI cable and the appropriate adapter:

      DSTREAM-PT connection.
    • If your target has separate debug and trace connectors, connect the DSTREAM-PT system with the debug cable bypassing the Parallel Trace probe:

      1. Connect the Parallel Trace probe to the target using the 60-way MIPI cable and appropriate adapter.

      2. Connect the DSTREAM-ST unit to the target using the appropriate JTAG or CoreSight ribbon cable.

      DSTREAM-PT debug bypass connection.
  6. Power up the target hardware.

    Note

    When the DSTREAM-PT system is powered-up, ensure that the air intakes on the top of each unit, are not blocked.

    • If the DSTREAM-ST unit overheats, it shuts down, all the LEDs turn off, and it remains in a safe state.

    • If the Parallel Trace probe overheats, it enters a low-power mode and all of its LEDs flash red.

    To re-initialize the DSTREAM-PT system, press the reset button on the rear of the DSTREAM-ST unit.
