Use the scan chain controls to configure a scan chain for the currently connected debug hardware unit:
As you add devices to the JTAG scan chain, a schematic diagram of the scan chain is created, as shown in the following example:
If a platform configuration file exists for your target, the Select Platform dialog box is displayed. If you want to use the platform configuration file:
Select the platform.
Click OK. A label identifying the platform is included at the top of the schematic diagram.
Managing devicesThe following buttons enable you to manage the devices in your configuration:
Click Add... to add a device to the scan chain.
When a device is selected in the schematic diagram:
click Remove to remove the selected device
click Properties... to update the properties for the selected device
click Configure to display the Device configuration settings
For a scan chain containing multiple devices, click:
Move Left to move the selected device to the left
Move Right to move the selected device to the right.
To display the device context menu, right-click on a device in the scan chain schematic. The following options are available for all devices:
Select Properties... to change the properties of the device.
Select Configuration... to configure the device.
Select Remove Device to remove the chosen device.
For a CoreSight system, the Read CoreSight ROM table option is available for the ARMCS-DP device. This enables your debug hardware to read the CoreSight ROM table.
To manage a platform file for your development board:
If a platform file exists, click Select Platform... to choose a platform that corresponds to your development board.
When a platform is assigned to your configuration, the Select Platform ... button changes to Clear Platform. Click Clear Platform to remove the platform assignment from your configuration.
If you are configuring a CoreSight system, click the Trace Associations ... to manage the CoreSight trace associations.
