AM625-Q1: The issue regarding the DebugP_log printing function

Part Number: AM625-Q1
Other Parts Discussed in Thread: SYSCONFIG

I have a question that I'd like to ask you for advice

One: I can print garbled characters in CCS using the vprintf_ function, but cannot print in the serial port tool as shown in the figure in Attachment 1. 

Two: DebugP_log debug cannot be accessed and there is no print either. As shown in Figure 2 of Attachment.

The current UART configuration is as follows :

/* UART Driver Parameters */

UART_Params gUartParams[CONFIG_UART_NUM_INSTANCES] =

{

    {

        .baudRate           = 115200,

        .dataLength         = UART_LEN_8,

        .stopBits           = UART_STOPBITS_1,

        .parityType         = UART_PARITY_NONE,

        .readMode           = UART_TRANSFER_MODE_BLOCKING,

        .readReturnMode     = UART_READ_RETURN_MODE_FULL,

        .writeMode          = UART_TRANSFER_MODE_BLOCKING,

        .readCallbackFxn    = NULL,

        .writeCallbackFxn   = NULL,

        .hwFlowControl      = FALSE,

        .hwFlowControlThr   = UART_RXTRIGLVL_16,

        .transferMode       = UART_CONFIG_MODE_POLLED,

        .skipIntrReg        = FALSE,

        .uartDmaIndex = -1,

        .intrNum            = 219U,

        .intrPriority       = 4U,

        .operMode           = UART_OPER_MODE_16X,

        .rxTrigLvl          = UART_RXTRIGLVL_8,

        .txTrigLvl          = UART_TXTRIGLVL_32,

        .rxEvtNum           = 0U,

        .txEvtNum           = 0U,

    },

};

I would like to ask: 1. Why doesn't DebugP_log take effect? 2. How to print normally?
