TM4C1294NCPDT INTERFACING WITH DS1307

I have written the program given below which is working perfectly with TM4C123gh6pm but the program get stuck in "while(I2CMasterBusy(I2C0_BASE))" when running in TM4C1294NCPDT.

Can anyone help???

void RTC_WRITE()
{
while(run_once)
{
I2CMasterSlaveAddrSet(I2C0_BASE, 0x68, false); // The address of the Slave is 0x68

I2CMasterDataPut(I2C0_BASE, RTCRegister); // Addr 0x00

I2CMasterControl(I2C0_BASE, I2C_MASTER_CMD_BURST_SEND_START);
while(!(I2CMasterBusy(I2C0_BASE)));

while(I2CMasterBusy(I2C0_BASE));
// SysCtlDelay(3000);

for (i=0;i<7;i++)
{
I2CMasterDataPut(I2C0_BASE, RTCSetup[i]); 
I2CMasterControl(I2C0_BASE, I2C_MASTER_CMD_BURST_SEND_CONT);
while(!(I2CMasterBusy(I2C0_BASE)));
while(I2CMasterBusy(I2C0_BASE));

}

I2CMasterControl(I2C0_BASE, I2C_MASTER_CMD_BURST_SEND_FINISH );

while(!(I2CMasterBusy(I2C0_BASE)));
while(I2CMasterBusy(I2C0_BASE));
run_once = false;
}

SysCtlDelay(550000); // writing time
}



int main(void)

uint32_t FREQ=0;
FREQ=SysCtlClockFreqSet((SYSCTL_XTAL_25MHZ | SYSCTL_OSC_MAIN | SYSCTL_USE_PLL |SYSCTL_CFG_VCO_480), 120000000);
