problem in accessing ps ethernet through sfp in zcu102(revision 1.0 and part no. xczu9eg-ffvb1156-2-i) evm.

Actually i am using ZYNQ Ultra+ MPSoC ZCU102 EVM for project xapp1306 in which i want to access PS ethernet using SFP ->pcs,pma/sgmii ->GEM0, but i m not able to do pinging in teraterm. it is showing like this-

                                                 -------lwIP TCP echo server------

                                       TCP packet sent to port 6001 will be echoed back

                                                      start PHY autonegotiation

                                          waiting for PHY to complete autonegatiation

i am able to do generate bit stream, export to hardware,program to FPGA, lunch SDK and build and debug the design.

done led, SW13 has 8 led in which DS38,DS40,DS43,DS44 is glowing. other led's is off.

I thought the problem in SDK side means PS side in .c files.

so plz share your knowledge to help me.

I am using zcu102 evm with part no. xczu9eg-ffvb1156-2-i and board revision 1.0

Could you please check the with the 100Mbps? force speed mode to 100 Mbps and test it again. 

Try to use the below patch: https://www.xilinx.com/support/answers/71295.html

Is the correct GT ref clock getting generated? Should be 156.25Mhz.

You can use the scui tool to check your clocks on the zcu102

Hi @vikaskanha ,

PS GEM is 1G speed.

Please check if you have - 125MHz for PS GEM.

That is the reason link is not up.
