MSPM0G3507: UART Configuration Confusion

Part Number: MSPM0G3507

Tool/software:

Hi all,

I am completely new to programming MCU's and am stuck on UART. I have followed the "uart_echo_interrupts_standby_LP_MSPM0G3507_nortos_ticlang" example and deconstructed it from higher level macros to something that I can understand. My code and the example code look exactly the same except for the two "ti_msp_dl_config.h" files. That seems to be the difference maker but I can't change that file. Can someone please tell me where I am going wrong with configuring UART? I posted my code below.

#include "ti_msp_dl_config.h"
static const DL_UART_Main_ClockConfig gUART_0ClockConfig = {
    .clockSel    = DL_UART_MAIN_CLOCK_LFCLK,
    .divideRatio = DL_UART_MAIN_CLOCK_DIVIDE_RATIO_1
};

static const DL_UART_Main_Config gUART_0Config = {
    .mode        = DL_UART_MAIN_MODE_NORMAL,
    .direction   = DL_UART_MAIN_DIRECTION_TX_RX,
    .flowControl = DL_UART_MAIN_FLOW_CONTROL_NONE,
    .parity      = DL_UART_MAIN_PARITY_NONE,
    .wordLength  = DL_UART_MAIN_WORD_LENGTH_8_BITS,
    .stopBits    = DL_UART_MAIN_STOP_BITS_ONE
};
volatile uint8_t gEchoData = 0;
int main(void)
{
    //SYSCFG_DL_init()
    DL_GPIO_reset(GPIOA);
    DL_GPIO_reset(GPIOB);
    DL_UART_reset(UART0);

    DL_GPIO_setPins(GPIOA, DL_GPIO_PIN_10 | DL_GPIO_PIN_11);
    DL_GPIO_enableOutput(GPIOA, DL_GPIO_PIN_10);

    DL_GPIO_enablePower(GPIOA);
    DL_GPIO_enablePower(GPIOB);
    DL_UART_enablePower(UART0);

    DL_GPIO_initPeripheralOutputFunction(IOMUX_PINCM21, IOMUX_PINCM21_PF_UART0_TX);
    DL_GPIO_initPeripheralInputFunction(IOMUX_PINCM22, IOMUX_PINCM22_PF_UART0_RX);

    DL_GPIO_initDigitalOutput(IOMUX_PINCM1);
    DL_GPIO_initDigitalOutput(IOMUX_PINCM37);

    DL_GPIO_setPins(GPIOA, DL_GPIO_PIN_0 | DL_GPIO_PIN_15);
    DL_GPIO_enableOutput(GPIOA, DL_GPIO_PIN_0 | DL_GPIO_PIN_15);

    /* Module-Specific Initializations*/

    DL_UART_setClockConfig(UART0, (DL_UART_Main_ClockConfig *) &gUART_0ClockConfig);

    DL_UART_init(UART0, (DL_UART_Main_Config *) &gUART_0Config);
    /*
     * Configure baud rate by setting oversampling and baud rate divisors.
     *  Target baud rate: 9600
     *  Actual baud rate: 9576.04
     */
    DL_UART_setOversampling(UART0, DL_UART_OVERSAMPLING_RATE_3X);
    DL_UART_setBaudRateDivisor(UART0, 1, 9);

    /* Configure Interrupts */
    DL_UART_enableInterrupt(UART0,DL_UART_INTERRUPT_RX);

    DL_UART_enable(UART0);
    DL_GPIO_enableOutput(GPIOA, DL_GPIO_PIN_10);

    NVIC_ClearPendingIRQ(UART0_INT_IRQn);
    NVIC_EnableIRQ(UART0_INT_IRQn);

    DL_SYSCTL_enableSleepOnExit();

    while (1) {
        __WFI();
    }
}

void UART_0_INST_IRQHandler(void)
{
    switch (DL_UART_getPendingInterrupt(UART0)) {
        case DL_UART_IIDX_RX:
            DL_GPIO_togglePins(GPIOA,DL_GPIO_PIN_0 | DL_GPIO_PIN_15);
            gEchoData = DL_UART_receiveData(UART0);
            DL_UART_transmitData(UART0, number);
            break;
        default:
            break;
    }
}
