8E1111 PHY tx_clk and rx_clk

[Altera_Forum]

Hi, 

 I have a custom board with altera Stratix 4 and 8E1111 PHY. i am trying to initiate the triple speed ethernet IP. a 25MHz crystal is connected with the PHY.  i have used the Simple Socket Server Software Example to initiate the IP.   i have tried to probe the tx_clk and rx_clk, clock signals from PHY. there is no clock coming from PHY.  is there any initiation needs to be performed to start the clock from PHY?  Thanks Vinay

Are you setting the Phy interface to RGMII?

No. i am trying to set it for GMII/MII mode. 

 the link you posted is not working.

My point was that you may have to set the interface you want. Try this link:

Thanks for the link.  

if i am following this configurations, how can i verify the setting?  i want to initiate the MII interface. can i check the behavior by probing the tx_clk/rx_clk signals?

Hi, 

 I just figured out that in the config[4] of 8e1111 connected to ground. so i think PHY is getting initialized in RGMII mode. is that true?  Thanks Vinay
