MPC8541/55 have CPM lite compare to CPM for MPC8560. The dport ram size is different. To make the FCC code work for CPM lite, the dport RAM pointers (various pointers used by the RISC) need to be adjusted.

My main question is: has anyone ever used FCC as ethernet on u-boot for mpc85xx, and with what success?

It works well for us on MPC8560, and also the FEC on the MPC8540 works fine. But the same code on the basicly the same hardware (just different CPU) fails for MPC8541 and MPC8555.

Best regards,
