I want to get a KC705 SFP ise project or a bit file.
i meet a question, when a use KC705 and ML505 to communicate using SFP ,the loopback test all passed, but when i connect two board together,it failed.

Can you elaborate what do you want exactly and how are you communicating when you are connecting KC705 and ML605.
How you are testing the loopback connection and how are driving the data,So that we can know what do you want and give
you some clues or inputs.

One of the below is might be the possible resons

Alternatively check with some SMA cable and see if the link works.
What SFP ise project are you looking for? Do you want that project to communicate with the External board. However the SFP is just a cable which is used for high speed communication and i guess there is no special connections to it.
There is an IBERT test with the SFP loopback. You can use it to test the SFP on the KC705 board itself but not with the external boards. Check this link - link for the instructions.

First,thanks for your response!
I use temac IP core connect to 1000baseX IPcore in KC705, when i use a 1000BASE-TX SFP and a network cable，then connect to the PC, no communication established. Bus when using PCS/PMA loopback the tx into rx,it works.
So,I want you can give me a KC705_temac_to_1000basex ISE project. I wonder something maybe changed in GTX

I ask an another question, I want to use two KC705 to establish a PCIE system.Use one KC705 to be a RC,and another to be a EP.
I make an additional board. it takes one KC705's TX to anothers RX pin, and use a 100M differntial clk to clock two kc705's pcie clk.
But when a program two bit file, the auto-negotiation failed.
what's the problem?
