Connecting the RVI hardware

The procedures described in this topic provide information on how to set up the hardware for the RVI unit.

Show/hidePrerequisites

Before setting up the RVI hardware, ensure that you have all the relevant items that comprise the RVI product kit.

You must also provide the following items:

  • a host computer that conforms to the host software and hardware requirements.

  • some target hardware containing a JTAG-capable device supported by RVI.

Show/hideProcedure

To connect the RVI run control unit to your host computer and to the target hardware:

  1. Ensure the RVI software is installed on the host computer.

  2. Connect the host computer to the RVI run control unit, using either the USB port or an Ethernet connection, as required. The following figure shows connections using both the USB and Ethernet cables, and the JTAG 20-way ribbon cable:

    Connect the host computer to the RVI run control unit as shown in the figure above, using either the USB port or an Ethernet connection, as required:

    • If you are connecting using the USB port, connect one end of the supplied USB cable to a USB port on the host computer, and the other end of the cable to the USB port on the run control unit.

      Note

      The USB drivers are installed with the RVI host software.

    • If you are connecting across an Ethernet network, connect the Ethernet port of the run control unit to a socket for the Ethernet network using the supplied RJ-45 Ethernet cable.

    • If you are using the cross-over cable, connect one end of the cross-over cable to the Ethernet port of the host computer, and the other end to the Ethernet port of the run control unit.

  3. Connect the RVI run control unit to the target hardware, using the appropriate cable:

    • If you want to use the highest JTAG clock speeds, or if you cannot position the run control unit close to the target hardware, use the Low Voltage Differential Signaling (LVDS) cable and probe:

      • connect one end of the supplied LVDS cable to the 40-way connector on the probe

      • connect the other end of the LVDS cable to the 40-way JTAG B socket on the RVI run control unit.

      • plug the supplied LVDS probe into the 20-way JTAG header on the target hardware

      Note

      Cable selection is performed when the RVI run control unit boots. If you change the cable, you must reboot the unit.

    • Otherwise, use the JTAG cable:

      • connect one end of the supplied JTAG cable to the 20-way JTAG header on the target hardware

      • connect the other end of the cable to the 20-way JTAG A socket on the RVI run control unit.

    The Insulation Displacement Connector (IDC) connectors used for these cables are keyed using a small protrusion that must be matched up with a slot in the header or socket.

  4. Power up the target hardware.

  5. Connect the external power supply to the RVI run control unit, and to the mains electricity.

  6. Switch on the power supply. The power LED and the expansion bus power LED both switch on.

  7. The RVI run control unit firmware is based on an embedded Linux kernel. Therefore, the unit takes a short time to boot up and establish either a network or USB connection. When the unit is booting:

    • The Compact Flash Activity (CFAC) LED lights up, and the STAT LED flashes.

      As the RVI run control unit boots, the STAT LED flash rate increases.

    • The unit detects which JTAG socket has a cable attached:

      • If RVI detects that the LVDS cable and probe are connected to JTAG B socket, it uses them. It also switches on the LVDS LED.

      • If RVI detects that a JTAG cable is connected to the JTAG A socket, the LVDS LED remains unlit.

    • When the STAT LED is permanently On, the RVI run control unit has finished booting, and is ready to use.

  8. If your RVI unit is connected to a network, you must now run the installed Config IP utility to configure the network settings.

    Note

    You have only to do the network configuration once.

    If the RVI unit is powered up with only a USB connection, it uses an IP address of 127.0.0.0. However, if a network cable is also attached, the IP address associated with the USB connection is the IP address that you have assigned to the RVI unit, or that it obtains from a Dynamic Host Configuration Protocol (DHCP) server.

Warning

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