Honored Contributor8E1111 PHY tx_clk and rx_clk
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 Vinay5 Replies
Altera_ForumAre 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. - Altera_Forum
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? - Altera_Forum
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
