[ixp1200] MicroC development.

Hi all, We are trying to run the examples from the IXP1200 Programming book (not using the ACE framework and debugging from the WorkBench) in the enp2505 board. They are working well in simulation mode, but once we indicate to run them in hardware, the rcv_rdy_lo register is always 0x00 even we are sending packets to the port 0. What do we need to activate the ports? We can see only the Hardware->Options->Ports tab to start them, is there something more we have to do? Thanks Jorge H
