STM32F437ZGT6 with KSZ8463MLI

Hello everybody.
I am working in a project with STM32F437ZGT6 MCU connected to a Micrel KSZ8463MLI Ethernet transceiver, via MII interface.
I am experimenting some trouble with the transmission data pins from STM32F4 (TXD0-3). With an oscilloscope, I have tested this pins and the signal is always the same (and wrong). Reception pins work fine.
Also I have tested the same source code with an STM32F4 evaluation board, and all work OK.
I wonder if anyone has had similar problems with Ethernet MII connection.

Thank you.
