    I assume that you don't have a license for the TSE-IP.

    In that case the TSE only keeps on working as long as you don't close that small message box that opens after downloading the logic onto your FPGA (using the JTAG port). If you close it, the TSE will not transmit any longer, but will keep on receiving, putting you on the wrong foot ...

    Thank you very much it is really very helpful reply. I really haven't a license, but i keep the JTAG connected all the time and also i didn't close the small window. Do you think it is not working also if i don't close the small window and keep the JTAG connected?

    :DReally thanks from my heart:D

    What software are you using to communicate with the TSE? Does it say anything?

    Could you check the ready signal from the TSE on the Avalon Stream input?

    Can you communicate with the PHY on the MDIO interface?

    Thanks Daixiwen for your reply.

    I am using NIOS II and i can write on any register i want, so i wrote on the command register

    to enable the TX and RX and after that the TX and RX leds are blinks and also the led in router

    is blink. The problem i can't capture any packet and the output from TSE always low.

    The ready signal always high, so that means it is fine.
