操作S3C6410的SPI端口驱动W5200网络模块,传输网络参数时发生错误,求解
先贴上主函数:
u8 MAC[6] = {0x00, 0x08, 0xDC, 0x01, 0x02, 0x03};//MAC Address

u8 IP[4] = {192, 168, 0, 103};//IP Address
u8 GateWay[4] = {192, 168, 11, 1};//Gateway Address
u8 SubNet[4] = {255, 255, 255, 0};//SubnetMask Address

void main(void)
{

    SYSTEM_InitException();
    SYSTEM_InitMmu();
   
    SYSC_POWER_Set();

    InitUartPort(0, FALSE);
    UART_InitDebugCh(0, 115200);
    UART_SetConfig(3,0,1,1,4,1,2,1,115200,1,1,1,1);
    UART_Open2(3);   
   
       GPIO_Init();
       printf("yanjiasi\n");
   
  
      
       Reset_W5200();  ///yanjiasi///5.23////
      
               
       WIZ_Config(); // network config & Call Set_network ();
   
   
   
      // Start Application         
        printf("\r\n\r\n------------------------------------------- \r\n");
        printf("TCP Server Loopback using W5200\r\n");  
    //    printf("UDP Loopback using W5200\r\n");
        printf("------------------------------------------- \n");
    //while(1) {
    //    tempa++;
    //    tempa=0;
    //    loopback_tcps(0, 5000);
    //    loopback_tcps(1, 5001);
    //    loopback_tcps(2, 5002);
    //    loopback_tcps(3, 5003);        
    //  loopback_tcpc(4, 5004);              
    //    loopback_udp(5, 3000);
    //    loopback_udp(6, 3001);
    //    loopback_udp(7, 3002);               
//}
}

贴上ResetW5200()的代码:
void Reset_W5200(void)
{
    GPIO_SetFunctionEach(eGPIO_E, eGPIO_0, 0x1);
       GPIO_SetPullUpDownEach(eGPIO_E, eGPIO_0, 0);
    Delay_us(2);  
    GPIO_SetPullUpDownEach(eGPIO_E, eGPIO_0, 1);
    Delay_ms(150);
    *rGPEDAT=1;
   
}

其实我有点怀疑我的w5200是否是重置过,重置的过程要求先给一个至少2us的低电平重置信号,然后加高电平至少150ms,我不明白S3C官网给的这个GPIO_SetPullUpDownEach()函数到底是什么意思,,反正最后就是拉高了电平。

再贴上 WIZ_Config()的代码:
void WIZ_Config(void)
{
  // Call Set_network(): Set network configuration, Init. TX/RX MEM SIZE., and  Set RTR/RCR
  Set_network(); // at util.c
}      

void Set_network(void)
{
        uint8 tmp_array[6];      
        uint8 i;
        
        // MAC ADDRESS
        for (i = 0 ; i < 6; i++)
        {
        Config_Msg.Mac[i] = MAC[i];
        }
        // Local IP ADDRESS
        Config_Msg.Lip[0] = IP[0]; Config_Msg.Lip[1] = IP[1]; Config_Msg.Lip[2] = IP[2]; Config_Msg.Lip[3] = IP[3];
        // GateWay ADDRESS
        Config_Msg.Gw[0] = GateWay[0]; Config_Msg.Gw[1] = GateWay[1]; Config_Msg.Gw[2] = GateWay[2]; Config_Msg.Gw[3] = GateWay[3];
        // Subnet Mask ADDRESS
        Config_Msg.Sub[0] = SubNet[0]; Config_Msg.Sub[1] = SubNet[1]; Config_Msg.Sub[2] = SubNet[2]; Config_Msg.Sub[3] = SubNet[3];
        
        setSHAR(Config_Msg.Mac);
//        setSUBR(Config_Msg.Sub);
        saveSUBR(Config_Msg.Sub);
        setGAR(Config_Msg.Gw);
        setSIPR(Config_Msg.Lip);

        // Set DHCP
        Config_Msg.DHCP = Enable_DHCP;   
        //Destination IP address for TCP Client
        Chconfig_Type_Def.destip[0] = Dest_IP[0]; Chconfig_Type_Def.destip[1] = Dest_IP[1];
        Chconfig_Type_Def.destip[2] = Dest_IP[2]; Chconfig_Type_Def.destip[3] = Dest_IP[3];
        Chconfig_Type_Def.port = Dest_PORT;

        //Set RTR and RCR register   
        setRTR(6000);
        setRCR(3);

        //Init. TX & RX Memory size
        sysinit(txsize, rxsize);
        
        printf("\r\n----------------------------------------- \r\n");                 
        printf("W5200E01-M3                       \r\n");        
        printf("Network Configuration Information \r\n");        
        printf("----------------------------------------- \n");                 
        
        printf("\r\nMAC : %.2X.%.2X.%.2X.%.2X.%.2X.%.2X\n", IINCHIP_READ(SHAR0+0),IINCHIP_READ(SHAR0+1),IINCHIP_READ(SHAR0+2),
                                                          IINCHIP_READ(SHAR0+3),IINCHIP_READ(SHAR0+4),IINCHIP_READ(SHAR0+5));
        
        getSIPR (tmp_array);
        printf("\r\nIP : %d.%d.%d.%d", tmp_array[0],tmp_array[1],tmp_array[2],tmp_array[3]);
        
        getSUBR(tmp_array);
        printf("\r\nSN : %d.%d.%d.%d\n", tmp_array[0],tmp_array[1],tmp_array[2],tmp_array[3]);
        
        getGAR(tmp_array);
        printf("\r\nGW : %d.%d.%d.%d", tmp_array[0],tmp_array[1],tmp_array[2],tmp_array[3]);
}


以setSHAR()为例子,就是写入物理地址:
void setSHAR(
    uint8 * addr    /**< a pointer to a 6 -byte array responsible to set the MAC address. */
    )
{
    IINCHIP_WRITE((SHAR0 + 0),addr[0]);
    IINCHIP_WRITE((SHAR0 + 1),addr[1]);
    IINCHIP_WRITE((SHAR0 + 2),addr[2]);
    IINCHIP_WRITE((SHAR0 + 3),addr[3]);
    IINCHIP_WRITE((SHAR0 + 4),addr[4]);
    IINCHIP_WRITE((SHAR0 + 5),addr[5]);
}
写函数的定义:
uint8 IINCHIP_WRITE(uint16 addr,uint8 data)
{
        IINCHIP_ISR_DISABLE();                      // Interrupt Service Routine Disable

    //SPI MODE I/F
    SPI_CSControl(0);
    delayLoop(0xffff);                           // CS=0, SPI start
   
    IINCHIP_SpiSendData((addr & 0xFF00) >> 8);  // Address byte 1
//    printf("step1\n");
    IINCHIP_SpiSendData(addr & 0x00FF);         // Address byte 2
    IINCHIP_SpiSendData(0x80);                  // Data write command and Write data length 1
    IINCHIP_SpiSendData(0x01);                  // Write data length 2
    IINCHIP_SpiSendData(data);                  // Data write (write 1byte data)
//    printf("step last\n");
    delayLoop(0xffff);
    SPI_CSControl(1);
    delayLoop(0xffff);                            // CS=1,  SPI end

    IINCHIP_ISR_ENABLE();                       // Interrupt Service Routine Enable
    return 1;
}
读函数的定义:
/**
@brief    This function reads the value from W5200 registers.
*/
uint8 IINCHIP_READ(uint16 addr)
{
    uint8 data;
        
    IINCHIP_ISR_DISABLE();                       // Interrupt Service Routine Disable
   
    SPI_CSControl(0);                             // CS=0, SPI start
    delayLoop(0xffff);
   
    IINCHIP_SpiSendData((addr & 0xFF00) >> 8);   // Address byte 1
    IINCHIP_SpiSendData(addr & 0x00FF);          // Address byte 2
    IINCHIP_SpiSendData(0x00);                   // Data read command and Read data length 1
    IINCHIP_SpiSendData(0x01);                   // Read data length 2      
    data = IINCHIP_SpiSendData(0x00);            // Data read (read 1byte data)
    delayLoop(0xffff);
   
    SPI_CSControl(1);                              // CS=1,  SPI end
    delayLoop(0xffff);
   
    IINCHIP_ISR_ENABLE();                        // Interrupt Service Routine Enable
    return data;
}
发送函数的定义:
u8  IINCHIP_SpiSendData(uint8 dat)
{
    printf("dat = %d ",dat);
    return(SPI_WriteByte(dat));
}

u8 SPI_WriteByte(u8 dat)
{
    SPI_channel *ch1;
    u8* uMTxBufAddr = (u8*)SPI_getBuffer(0, TRUE, TRUE);
    u8* uMRxBufAddr = (u8*)SPI_getBuffer(1, FALSE, TRUE);
    ch1=SPI_open(TEST_CHANNEL1,SPI_MASTER, SPI_TEST_CPOL, SPI_TEST_FORMAT, CLK_SOURCE, SPI_SPEED,
              SPI_TEST_CHANNEL_WIDTH, SPI_TEST_BUS_WIDTH, NULL );
    uMTxBufAddr[0]=dat;
    printf("uMT[0] = %d ",uMTxBufAddr[0]);
    SPI_transaction(ch1, SPI_POLLING_MODE, uMTxBufAddr, uMRxBufAddr, 1, NULL);
    printf("uMR[0] = %d\n",uMRxBufAddr[0]);
    return uMRxBufAddr[0];
   
}
SPI_open()参数:
#define SPI_BUFFER_SIZE 0x100000            // Reserved Buffer Size.
#define SPI_SPEED 20000000    // .            // Transfer Speed, that is limit to clock source.
#define SPI_DATA_COUNT (0x4)                // max Buffer size.
#define CLK_SOURCE SPI_PCLK                    // SPI Clock Source.
#define TEST_CHANNEL0 0                        // SPI Test Peripheral 0
#define TEST_CHANNEL1 1                        // SPI Test Peripheral 1
#define SPI_TEST_CPOL    SPI_ACTIVE_LOW        // SPI Test polarity
#define SPI_TEST_CHANNEL_WIDTH SPI_BYTE    // SPI Channel Size
#define SPI_TEST_BUS_WIDTH SPI_WORD        // SPI Bus Size
#define SPI_TEST_DMA_TYPE SPI_DMA_SINGLE    // SPI DMA Mode
#define SPI_TEST_FORMAT SPI_FORMAT_A        // SPI Test Phase
// When polling mode test, must using board to board test.
#define SPI_TEST_TRANSFER_MODE SPI_POLLING_MODE    // SPI transfer mode selection

代码先贴到这里,请大神们给意见,我再贴出程序运行的结果截图,就是读出来的不对:
