7.2.7. Troubleshooting RealView ICE connections

This section describes problems you might encounter when attempting to connect to a RealView ICE unit, and what you can do to solve them:

Multiple programs attempting to scan

Only one program can scan the TCP/IP network for available RealView ICE units. If another program is scanning the network, the RVI Update application displays the error message shown in Figure 7.5.

You must stop one of the programs from scanning the network. To do this, click the Scan tool.

USB server not accessible

If the USB server is not accessible, the error message shown in Figure 7.6 appears:

This indicates a problem with your RealView ICE installation. Click OK. If you do not want to connect to any devices over a USB connection, you can continue using RealView ICE over only TCP/IP connections. If you want to connect to a device using USB, you must reinstall RealView ICE. If the error persists, there might be a problem with your operating system.

Timeouts

The default timeout for establishing a TCP/IP connection is 5 seconds. If you repeatedly get timeouts when attempting to connect to a RealView ICE run control unit, you can change this setting. To do this:

  1. If the environment variable RVI_COMMS_CONNECT_TIMEOUT does not already exist, then create it.

  2. Set the value of this variable to the timeout that you want, in seconds. This must be an integer in the range 0-120.

For details of how to create and set an environment variable, see the documentation for the operating system that is supplied with your host computer.

Other active connections

If you connect to a RealView ICE run control unit that has other active connections, the RVI Update application displays the error message shown in Figure 7.7.

If you continue, the changes that you make might interfere with the correct operation of these applications. Do one of the following:

  • ensure that the other applications are disconnected, and then click Yes to continue using the RVI Update application

  • click No to stop using the RVI Update application, and try again later.
