questions about tse with phy(rtl8201cp)

hi,everyone.

I have been in trouble with tse mac communication with phy(rtl8201cp).

in the sopc hardware design, add the tse(v7.2) ipcore, and select the 10/100Mb small mac. in the nios IDE software design, use the simple_socket_sever template, and not change anything of the program.

download the *.sof file into fpga, and run software as nios hardware, and get info as follow:

nios2-terminal: connected to hardware target using JTAG UART on cable

nios2-terminal: "USB-Blaster [USB-0]", device 1, instance 0

nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)
