This target interface supportsprogram loading and debugging of both RAM and FLASH based applications. Thereare two variants of the Wiggler, one with 20 pins and one with 14 pins, and both aresupported.Connection properties•Parallel Port The parallel port connection to use to connect to the target.146 Chapter 13 Target interfaces
•Parallel Port Address The base address of the currently connected parallel port (ifavailable).•Parallel Port Sharing If set to Yes, parallel port may be shared with other devicedrivers and programs. If set to No, the target interface will demand exclusive useof the port.Interface properties•Version The device driver version information.Current device properties•Device Type The JTAG device ID of the currently connected device.JTAG properties•Identify Target Specifies whether the target should be identified on connection.Use this setting with caution as setting this to "No" disables the checks carried outon connection that the JTAG interface is functioning correctly and may makean malfunctioning JTAG connection appear as if it is working.•Invert nSRST Specifies whether the nSRST signal should be inverted.•JTAG Clock Divider The value to divide the JTAG clock frequency. This featureallows the JTAG clock frequency to be reduced in order to allow CrossStudio tocommunicate with boards with unreliable target interfaces.Loader properties•Erase All If set to Yes, all of the target's FLASH memory will be erased prior todownloading the application. This can be used to speed up download of largeprograms as it generally quicker to erase a whole device rather than individualsegments. If set to No, only the areas of FLASH containing the program beingdownloaded will be erased.•Erase All Timeout The timeout period for an erase all operation in milliseconds.Target properties•Debug Interface Type The type of debug interface that the target has. Note that thevalue of this property will be automatically set to a project's ARM DebugInterface property on connection.Chapter 13Macraigor Wiggler (20 and 14 pin) Target interface147
