eeprom writiand reading problem with c2000 TMS320F28027 controller

Other Parts Discussed in Thread: TMS320F28027, CONTROLSUITE

Hi friend ,

I have return eeprom interface with c2000  TMS320F28027 through i2c . I have problem in read and write please any one help me

this is my code...

    while(I2caRegs.I2CSTR.bit.XRDY == 0){};
    I2caRegs.I2CDXR = *txBuf_pu8;

}

void i2cRead(Uint16 memAddr_u16, unsigned char *rxBuf_pu8, Uint32 rxDataLen_u32)
{
    Uint32 i = 0;
    I2caRegs.I2CSAR = I2C_SLAVE_ADDR;             //Set slave address
    I2caRegs.I2CCNT = 2;                         //Set count to 2 address bytes
    I2caRegs.I2CDXR =((memAddr_u16 >> 8) & 0xFF);            //Send eeprom high address
    I2caRegs.I2CMDR.bit.TRX = 1;                 //Set to Transmit mode
    I2caRegs.I2CMDR.bit.MST = 1;                 //Set to Master mode
    I2caRegs.I2CMDR.bit.FREE = 1;                //Run in FREE mode
    I2caRegs.I2CMDR.bit.STP = 0;                 //Dont release the bus after Tx
    I2caRegs.I2CMDR.bit.STT = 1;                 //Send the start bit, transmission will follow
    
    while(I2caRegs.I2CSTR.bit.XRDY == 0){};         //Do nothing till data is shifted out
    I2caRegs.I2CDXR = ( memAddr_u16 & 0xFF );              //Send eeprom low address
    I2caRegs.I2CCNT = rxDataLen_u32;                //read 5 bytes from eeprom
    I2caRegs.I2CMDR.bit.TRX = 0;                 //Set to Recieve mode
    I2caRegs.I2CMDR.bit.MST = 1;                 //Set to Master mode
    I2caRegs.I2CMDR.bit.FREE = 1;                //Run in FREE mode
    I2caRegs.I2CMDR.bit.STP = 1;                 //Stop when internal counter becomes 0
    I2caRegs.I2CMDR.bit.STT = 1; //Repeated start, Reception will follow
    for(i = 0; i < rxDataLen_u32; i++)
    
        while(I2caRegs.I2CSTR.bit.RRDY == 0){};     //I2CDRR not ready to read?
        *rxBuf_pu8 = I2caRegs.I2CDRR;
        rxBuf_pu8++;
    }
}


void main(void)
{
       Uint16 address = 0x0005;
       unsigned char txdata = 'H';
       unsigned char rxdata = 0;

       InitSysCtrl();
       InitI2CGpio();
       DINT;
       InitPieCtrl();
       IER = 0x0000;
       IFR = 0x0000;
       InitPieVectTable();
       i2cInit();
       EINT;

       i2cWrite( address, &txdata, 1);

       while(1)
       {
           i2cRead( address, &rxdata, 1);
       }
