ML405 ethernet

I am trying to send UDP packets from the ML405 and I send my data to the expansion header on the board, it looks perfect( ie the same as the timing diagram in the data sheet for marvell's phy).  Although I am not getting any data out of the RJ-45 connector.  Am I missing something?  I am currently utilizing the 25MHz clock from the PHY and throw the tx_en on the rising edge.  Then on the next falling edge I send my 4bits of data consecutively on each falling edge after that.  Then on the last 4bits I throw the TX_EN low.  Any help would be great.

Re: ML405 ethernet

Are you driving the PHY reset pin?
