Connecting the RVT hardware

Before you can capture trace from an ETM provide, you must connect the hardware for RVT.

Show/hidePrerequisites

Beforeconnecting the RVT hardware, ensure that you have all the relevant items from the RVT product kit.

When considering your system requirements, you must also provide some target hardware containing a device supported by RVT.

Show/hideConnection instructions

To connect RVT hardware:

  1. Ensure that the RVI unit is disconnected from the power supply and from the target board.

    Warning

    Failure to remove the power from the RVI unit before connecting it to the RVT unit can cause damage to the hardware and/or personal injury.

  2. Remove the plastic ventilation grill from the top of the RVI unit by unclipping it.

  3. Screw the four 16mm plastic spacers onto the four 8mm plastic spacers exposed inside the RVI unit, as shown in the following figure.

  4. Using the four lengthened threaded inserts as guides, plug the RVT unit into the RVI unit. Apply downward pressure directly above the two connectors to ensure a positive fit.

  5. Screw the four 8mm plastic spacers onto the four threaded inserts exposed through the PCB inside the RVT unit. This fastens the two units together, making the assembly safe for transportation. The following figure shows a profile view of the connected units.

  6. Clip the plastic ventilation grill that you removed from the RVI unit onto the top of the RVT unit.

  7. For up to 16-bit trace port widths, connect one end of the interface cable to the 60-way trace probe connector of the RVT unit, and the other end of the cable to the trace probe.

    Connect one end of the JTAG cable or Low Voltage Differential Signaling (LVDS) probe to the respective JTAG socket on the RVI run control unit. Connect the other end to the 20-way JTAG header on the target hardware. The following figure shows a typical system for RVT.

    If your target board does not have separate trace and RVI sockets, use the RVI socket on the trace probe as shown in the following figure.

    Plug the trace probe into the trace connector on the target board.

    32-bit trace port widths are supported by RVT2. Connect the split-ribbon cable to the 40- and 60-way trace probe connectors on the RVT unit, and connect the other end of the cable to the 32-bit dual-Mictor probe.

    Plug the dual-Mictor probe into the vertical plug-in trace connector on the target board. See the following figure.

    Extender cables can be used if necessary, for example when using dual-Mictor trace probes.

  8. Connect the RVI unit to a network shared by a PC running a debugger.

  9. Power up the RVI unit and the target board. The RVT unit is powered from the RVI unit, and does not require a separate power supply.

Warning

Do not obstruct the ventilation grills on the top of the RVT unit or the bottom of the RVI unit, because doing so causes the units to overheat.

Note

You can also use the following alternative connections:

  • use a USB cable to connect the RVI run control unit directly to your host workstation

  • connect one end of the JTAG cable or LVDS probe to the trace probe JTAG socket.
