Dear Community,

 

I have i.mx6dl based board with Micrel KSZ9021 PHY.  PHY needs 25 MHz clock from MX6 MAC to generate 125 MHz reference clock, in its RGMII mode. 

 

I am using u-boot 2009.08.  There is 6 MHz clock at RGMII_TXC pin. Is it possible to output 25 MHz clock from this pin?  If yes, How can I do it?

 

Thanks and best regards.
