Run and Debug problems

[jacoblòpez]

Hello!  I'm using i.mx53 jumpstart kit. I have a new problem, I have configured the network using DCHP, I used the ping command and the connection works very well, but when I try to  debug  the application it goes wrong, the console display that the connection is refused and the remote console don't show  anything, I have attached the screenshots of the Run configuration Display and Debug configurations display, Thanks!

P.D.   

I'm using Ubuntu 12.04  on a native PC, wired local network and serial USB converter
