Virtex-5 Embedded Ethernet MAC TX Problem

Dear Experts

                       I am using ml507 board with fx70T device and trying to run example design of loopback. Its my first fpga development experience. I am generating the core with the configuration

                      1- GMII interface 1Gb/s fixed speed 

      2- Remaining are on default no changes

                       3- Host type None.

I am using an application name ostinato to send frames to the board. Rx LED on the board blinks and I can see the sent frames on the PC side. But no frames are sent back by the Board. I would be highly thankfull for your support.

Waiting for your reply.

 

Regards

Re: Virtex-5 Embedded Ethernet MAC TX Problem

You are more likely to get help if you post the UCF, noting where you think the problem area might be...
