Are you using the TivaWare drivers? All 8 UARTs are configured the same way. You configure the appropriate pins and then use the appropriate base address UART0_BASE ... UART7_BASE. Can you describe the problem you are having?

Hi Bob,

                I am not using any drivers. I am accessing uart through registers 

SYSCTL_RCGCUART_R |= 0x00000020;
SYSCTL_RCGCGPIO_R |= 0x00000010;
GPIO_PORTC_LOCK_R = 0x4C4F434B;
GPIO_PORTC_CR_R |= 0x000000FF;
GPIO_PORTC_AFSEL_R |= 0x00000030;
GPIO_PORTC_PCTL_R |= 0x00110000;
GPIO_PORTC_DEN_R |= 0x00000030;
UART5_CTL_R &= ~(0x00000001);
UART5_IBRD_R = iBaudrate;
UART5_FBRD_R = intBaudrateFloat;
UART5_LCRH_R = 0x00000060;
UART5_CC_R = 0x00000000;
UART5_CTL_R |= 0x00000301;

i tried like this but i can't transmit or receive data

Thanks in advance
