2.2.2. Connection instructions

You must connect the Multi-ICE interface unit to the your workstation and to the target hardware. An example is shown in Figure 2.2.

Figure 2.2. Multi-ICE interface unit cable connection

To connect the hardware together:

  1. Ensure the Multi-ICE software is installed on the host machine. This is described in the section on installing the Multi-ICE software in the Multi-ICE Installation Guide.

  2. Connect one end of the parallel cable to the parallel port of the host computer (variously labeled Printer, Parallel, IEEE 1284, or with a graphic), and the other end of the cable to the Multi-ICE interface unit.

  3. Ensure that the Multi-ICE unit has a power source:

    • Determine the Model No. of your Multi-ICE interface unit. This is printed on the underneath of the unit. If the interface unit is model 83 or later, and it is to draw power from the target, you must ensure that a link is fitted to jumper J8. This jumper is situated under the removable cover on the interface unit, as shown in Figure 2.3.

      Figure 2.3. Location of jumper J8

    • If independent power to the Multi-ICE interface unit is required, for example because the target cannot supply sufficient current or because you are connecting to an already-running target, you must connect the external power supply to the Multi-ICE interface unit and switch it on.

      Note

      If you are connecting Multi-ICE to hardware that is powered and running, for example to find out what is happening, refer to Post-mortem debugging.

  4. Connect one end of the JTAG cable to the JTAG connector on the Multi-ICE interface unit, and the other end of the cable to either:

    • the JTAG connector on the target board, if this is a 20-way IDC connector conforming to the Multi-ICE connection standard

    • the 20-way connector on the optional JTAG interface adaptor, if the target JTAG connector is a 14-way IDC connector conforming to the EmbeddedICE Interface Unit connection standard.

    The IDC sockets used for this cable are keyed using a small protrusion that must be matched up with a slot in the plug.

    If the target board has another variety of connector, see Connecting to nonstandard hardware.

  5. If it is not already powered up, switch on the power to the target board.
