[ixp1200] Running sample application on ENP2611 board

Folks, Recently we got ENP2611 board based on IXP2400. After successfully installed and boot, we are confused to run a simple sample application on the hardware. It is really different with our previous one- ENP2505 based on IXP200. Can you share your experience of playing ENP2611 or kindly point me the right documentation for it? Thanks in advance, Ning
