Debug error in visual studio 2013

I did everything almost correctly.I Ran the debugger client on the target board. Captured the IP address from the message displayed. Configured the IP address in the Visual Studio project (project->Properties. Under Configuration Properties, select Debugging. Inserted the target IP Address. Now why this error is occuring ? Please suggest me a solution . I have attached the following occured error message.

Dear @sth

Keep the Debugger Client application running on the target. Otherwise the debugger will only connect for a short time window.

If this does not help, please try the following:

  1. ping the IP address from your PC - do you get a proper response from the Colibri?
  2. Enable the debug messages and send us the complete debug log from booting the device until the debug connection fails. Is there any hint about the failure reason?
