# W5500 interface with TI

## Question

Asked by Akash Ahirwar on 2024-01-02 in Ethernet Chips.

I implement version read command is working and I get 0x04.
but i try to ping from my system mi not getting ping response.
please look into the configurations. and please let me know if there is something wrongs.

void WInzip_init()
{

// Read_adddress = ((Uint32)(0x00000039) << 8) | Read_OPCODE;
// IINCHIP_READ_add_data(Read_adddress);

// Write_adddress = ((Uint32)IP_adddress << 8) | Write_OPCODE;
// IINCHIP_WRITE_BUF_data(Write_adddress,0x00,10);
//
// Read_adddress = ((Uint32)IP_adddress << 8) | Read_OPCODE; // 0x00 is the control phase bit sets
// IINCHIP_READ_Buf_data(Read_adddress,&read_data[0],10);

```
// comman registers

Write_adddress = ((Uint32)Base_address << 8) | Write_OPCODE;
IINCHIP_WRITE_add_data(Write_adddress , MR_R);
```

// Read_adddress = ((Uint32)Base_address &lt;&lt; 8) | Read_OPCODE;

Read_adddress = ((Uint32)Base_address << 8) | Read_OPCODE;  // 0x00 is the control phase bit sets

```

//Socket Registers Settings//

```
Write_adddress = ((Uint32)Base_address << 8) | Write_Socket_OPCODE; // tcp 0x01

```

```
Read_adddress = ((Uint32)Base_address << 8) | Read_Socket_OPCODE;
IINCHIP_READ_add_data(Read_adddress);

Write_adddress = ((Uint32)0x00000001 << 8) | Write_Socket_OPCODE;
IINCHIP_WRITE_add_data(Write_adddress , Sn_CR);

Write_adddress = ((Uint32)0x00000001 << 8) | Write_Socket_OPCODE;
IINCHIP_WRITE_add_data(Write_adddress , Sn_CR);

Read_adddress = ((Uint32)(0x00000003) << 8) | Read_Socket_OPCODE;  // check port is init or not
IINCHIP_READ_add_data(Read_adddress);

Read_adddress = ((Uint32)Base_address << 8) | Read_Socket_OPCODE;  // 0x00 is the control phase bit sets
IINCHIP_READ_Buf_data(Read_adddress,&read_socket_data[0],10);

//
// Read_adddress = ((Uint32)Base_address &lt;&lt; 8) | 0X01;
// IINCHIP_READ_add_data(Read_adddress);

}

Thank in advance.

when i setting Sn_CR for OPEN Socket and check Sn_SR status it is showing me 0x00 it means it is not set. please resolve my problem
