RealView Debugger might fail to connect to your chosen debug target because of the following reasons:
you do not have a valid license to use the debug target (RealView Debugger displays a message if this is the case)
the debug target is not installed or the connection is disabled
the target hardware is in use by another user
the connection has been left open by software that exited incorrectly
the target has not been configured, or a configuration file cannot be located
the target hardware is not powered up ready for use
the target is on a scan chain that has been claimed for use by something else
the target hardware is not connected.
If RealView Debugger attempts to make a connection and fails, it normally displays a list selection box to offer possible actions, shown in Figure 3.9. Some Target Access interfaces, such as Multi-ICE, might also display their own dialog boxes or messages.
The message displayed at the top of the selection box indicates the type of problem encountered by RealView Debugger. The message displayed, and the options available, depends on the Target Access you are using:
If you have identified the cause of the failure and corrected it, for example you have connected a board or switched on power, then:
Select Retry (you fix the problem first)
Click OK to connect.
To close the list selection box and display the Connection Properties window where you can edit your target configuration details (see the RealView Debugger v3.0 Target Configuration Guide for details):
Select Edit Board-file to give the specific pathname...
Click OK.
Save the new settings and then close the Connection Properties window before trying to make the connection using the Connection Control window.
To display the configuration dialog box for the target:
Select Configure Device Information...
Click OK.
You must configure certain targets before you can make your first connection, for example RealView ICE, Multi-ICE, or RealMonitor. See the RealView Debugger v3.0 Target Configuration Guide for more details.
To close the message box and abandon the connection, click Cancel.
