2.2.2. Connection instructions

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

  1. Ensure the RealView ICE software is installed on the host computer. See the RealView ICE Installation Guide for information on how to do this.

  2. Connect the host computer to the RealView ICE run control unit, using either the USB port or a TCP/IP network connection, as required (see Figure 2.1):

    • 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 RealView ICE 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 RealView ICE 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 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 RealView ICE 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 RealView ICE 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 RealView ICE run control unit.

    The 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.

    Caution

    If the target hardware does not have a 20-way IDC connector that conforms to the current ARM JTAG connection standard (as described in Appendix A JTAG Interface Connections), see Using nonstandard connectors.

  4. If you are using RealView Trace, you have to connect the RealView Trace unit to the RealView ICE unit and to the target board. See Connecting the RealView Trace hardware for information on how to do this.

  5. Power up the target hardware.

  6. Connect the external power supply to the RealView ICE run control unit, and to the mains electricity.

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

  8. The RealView ICE 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 CFAC LED lights up, and the STAT LED flashes.

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

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

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

      • If RealView ICE 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 RealView ICE run control unit has finished booting, and is ready to use.

  9. If your RealView ICE unit is connected to a network, you must now run the Config IP application to configure the network settings, as described in Chapter 3 Configuring RealView ICE Networking.

    Note

    You have only to do the network configuration once.

    If the RealView ICE 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 RealView ICE unit, or that it obtains from a DHCP server.

Warning

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