On Windows Vista and Windows 7, launching a debug configuration with platform as Cortex-A8 RTSM or FVP may give the following error:

Windows cannot find 'c:\windows\system32\telnet.exe


DS-5 Debugger uses telnet capabilities of your computer for a debug session over serial connection to the RTSM and FVP. This error occurs when you try to connect to the RTSM and FVP from the debugger and the telnet client is disabled. The telnet client is not enabled by default on Windows Vista and Windows 7.


Enable telnet client on your computer and restart the debug session. To enable telnet client on Windows Vista and Windows 7:

  1. Open Control Panel from the Windows Start menu.
  2. Select Programs.
  3. Under Programs and Features, click Turn Windows features on or off.
  4. From the list that appears, select the Telnet Client checkbox to enable telnet.
  5. Click OK to close the dialog.
