Setting the Cable Options
After connecting the cable for download, verification, or debug, power your target board to enable the software to communicate with the cable and invoke the Hardware Debugger. You must then set the cable options.
- Select Cable
Communications to invoke the Communication Setup dialog box, shown in the “Communication Setup Dialog Box” figure.
- In the Cable Type field, select the cable type that you installed for downloading. The parallel cable is supported for the PC only.
- In the Port Name list box, select the port to use for downloading and readback. If the port name you want is not listed, select the blank name from the list box and type in the new port name. This list box saves up to two user-specified port names.
The Port Name list box contains a list of valid ports for the platform, as shown in the “Serial and Parallel Ports” table. If you selected a serial cable or an XChecker cable, the serial ports are displayed. If you selected a parallel cable, the parallel ports are displayed.
