STM32F107 + DP83848(Ethernet controller)

I have a problem with the ethernet controller DP83848 in combiantion with a STM32F107.  I designed a PCB with these two components, I copied a part of the schematic of the STM3210C-EVAL board. I am using the RMII mode so I didn't connect the lines needed for MII. I know the software works because I tested it with the EVAL board. I suspect that the ethernet controller works because I can read and write to it. My problem is that I am getting a lot of false carrier sense errors from the ethernetcontroller so I think it has something to do with receiving data over ethernet. Does anybody have any experience with this problem or the ethernetcontroller?

Thank You,
