Using TSE MAC+ 88e1111 PHY on De2i 150 board to send data between FPGA and PC

Hello，

I have tried what you mentioned above. Firstly I used .sof file to configure my FPGA,which is similar to the document you mentioned above.Secondly,I copied the tse_tutorial.c file to my Nios II project, then I made some changes to fit my appliciation

volatile int * tse = (int *) 0x12042000;

printf("%x",*(tse + 2));

// Initialize the MAC address

*(tse + 3) = 0x116E6001;

*(tse + 4) = 0x00000F02;

// Specify the addresses of the PHY devices to be accessed through MDIO interface

*(tse + 0x0F) = 0x10;

//*(tse + 0x10) = 0x11;

// Write to register 20 of the PHY chip for Ethernet port 0 to set up line loopback

//*(tse + 0x94) = 0x4000;

// Write to register 16 of the PHY chip for Ethernet port 1 to enable automatic crossover for all modes

*(tse + 0x90) = *(tse + 0x90) | 0x0060;

// Write to register 20 of the PHY chip for Ethernet port 2 to set up delay for input/output clk

*(tse + 0x94) = *(tse + 0x94) | 0x0082;

// Software reset the second PHY chip and wait

*(tse + 0x80) = *(tse + 0x80) | 0x8000;

while ( *(tse + 0x80) & 0x8000 );

printf("PHY reset over");

But it seems that it failed to complete the Software reset the second PHY chip and wait . Can you tell me what i should solve this problem ?
