trouble reading uart

I have 2 UARTs I am using on the K02 Board I have.


One is set up for DEBUG and it works normal. I can Use Interrupts no problem.

When I configure the 2nd UART, UART1 I cannot read anything out of the port. I cannot use Interrupts as well.


Here is my configuration:


/*! User configuration structure 0 */

/*! fsl_uart1 configuration structure */

const uart_user_config_t fsl_uart1_InitConfig0 = {

    .baudRate = 115228U,

    .parityMode = kUartParityDisabled,

    .stopBitCount = kUartOneStopBit,

    .bitCountPerChar = kUart8BitsPerChar,



static uart_status_t uart1_init(void)


    uart_status_t status = UART_DRV_Init(FSL_FSL_UART1, &uart1_state, &fsl_uart1_InitConfig0);


    return status;



I have tried reading using blocking and also using an Interrupt and It never reads anything. I can transmit out no problem but I cannot read.

I know it is not a hardware issue because when i switch this port to the debug instance it works correctly. Something must be configuring it differrently when used as Debug.


Please Help!!!
