KSZ9131RNX UltrazedEV SOM PHY Problem

Hi,

I am tring to work on Micrel KSZ9131RNX PHY on RGMII port of Ultrazed MPSOC. 

PHY Address : 0x3

PHY MODE: 1110 -> Full Dublex 1000GigE

I both tried LWIP Echo server and UDP IPERF Client, but i couldnt see the ethernet packages on wireshark. Status leds are flickering on board but i cannot see the packages. 

Is there any register settings or something to work it. BTW, Marvell PHY was working without any issue previously with same board. Pls see the schematics for further connection if needed.

Hi @umtkyck ,

Lwip does not support all PHYs. Please check the following AR:

You will have to manually initialize the PHY.

Don’t forget to reply, kudo, and accept as solution.

If starting with Versal take a look at our Versal Design Process Hub and our Versal Blogs and our Versal Ethernet Sticky Note.
