Connect and power up the DSTREAM-ST unit
This topic describes how to connect your DSTREAM-ST unit to your host PC and target hardware.
- You must have installed Arm Development Studio to access the software drivers and debug hardware configuration utilities.
- Your target hardware must contain a debug interface supported by DSTREAM-ST. For a list of supported connectors, see Target interface connectors the Arm® DSTREAM-ST System and Interface Design Reference Guide.
To connect the DSTREAM-ST unit between your PC and the target hardware, you need:
- The DSTREAM-ST unit.
- The power adapter for the DSTREAM-ST unit and the mains cable for the power adapter that is appropriate for your region.
To connect the DSTREAM-ST unit to the PC or the network, you need either:
- The USB cable, to connect the DSTREAM-ST unit directly to the PC using the USB 3.0 port.
- The RJ-45 Ethernet cable, to connect the DSTREAM-ST unit to the network.
- To connect the DSTREAM-ST unit to the target hardware, you need a target-compatible cable. For a list of provided cables, see Arm® DSTREAM-ST box contents.
NoteIf the DSTREAM-ST unit or the target hardware are not properly earthed, potential differences can occur between them, causing unwanted pulses in the debug interface during connection. This can cause unwanted resets to occur.
Connect the host PC to the DSTREAM-ST unit as shown in the following figure. Use either the USB port or a TCP/IP network connection, as required:
Figure 2-1 Connecting the host PC to the DSTREAM-ST unit.
If you are connecting using the USB port, connect the DSTREAM-ST unit to the host PC using the supplied USB 3.0 cable.
NoteThe USB drivers are provided with Arm Development Studio. For more information, see the USB driver installation topics: Install the USB drivers for the DSTREAM-ST unit on Windows or Install the USB drivers for the DSTREAM-ST unit on Linux.
- If you are connecting across an Ethernet network, connect the DSTREAM-ST unit to the local network using the supplied RJ-45 Ethernet cable.
Power up the DSTREAM-ST unit.
When you power up the DSTREAM-ST unit, it follows a boot sequence. The LEDs identify the progress of the boot sequence. For more information, see DSTREAM-ST unit boot sequence.
NoteIf you need to reset the DSTREAM-ST unit, press the reset button on the rear of the DSTREAM-ST unit.
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.
Connect the DSTREAM-ST unit to the target hardware. Use the appropriate cables and connector. Each connector, and the appropriate cable to use for that connector, is described in Target interface connectors in the Arm DSTREAM-ST System and Interface Design Reference Guide.
WarningWhen connecting the DSTREAM-ST unit 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 the DSTREAM-ST unit. For supported pinout information, see the Arm DSTREAM-ST System and Interface Design Reference Guide.
Power up the target hardware.
When the DSTREAM-ST unit is powered-up, ensure that the air intake, on the top of the unit, is not blocked.
If the DSTREAM-ST unit overheats, it shuts down, all the LEDs turn off, and it remains in a safe state.
To re-initialize the DSTREAM-ST unit, press the reset button on the rear of the DSTREAM-ST unit.
