MCF54451EVB and MQX 3.6.1

Has anyone been able to succesfull port the MCF54455EVB MQX to the MCF54451EVB ? I am talking about basit port , like networking.


I was able to update for the diference in hardware (eg PHY) but with limited results. There is something extremely strange happening with the network trafic. For example, I initialize the fec0 and assign a static ip, then I try a ping to the host (connected vai twisted cable). I see the packets beeing receved at the host - ARP request, then ARP reply sent back, then the sequence repeats.  It seems that the ARP reply is not properly received on the MQX  side.  A breakpoint in the MCF5XXX_FEC_process_rx_bds() shows that packets are received, but only broadcast packets, and no packets that have as destination the preset MAC.  Of course, as a fun exercise I tried to enable the MCF5XXX_FEC_RCR_PROM, without any help.
