here is my code:

/*

#include <xdc/std.h>

#include <xdc/runtime/Error.h>
#include <xdc/runtime/System.h>

#include <ti/sysbios/BIOS.h>

#include <ti/sysbios/knl/Task.h>
#include <ti/board/board.h>
/*
 *  ======== taskFxn ========
 */
Void taskFxn(UArg a0, UArg a1)
{
    System_printf("enter taskFxn()\n");

    Task_sleep(10);

    System_printf("exit taskFxn()\n");

    System_flush(); /* force SysMin output to console */
}

/*
 *  ======== main ========
 */
Int main()
{ 
    Board_initCfg boardCfg;
    boardCfg = BOARD_INIT_PINMUX_CONFIG | BOARD_INIT_UART_STDIO;
    Board_init(boardCfg);

    Task_Handle task;
    Error_Block eb;

    System_printf("enter main()\n");

    Error_init(&eb);
    task = Task_create(taskFxn, NULL, &eb);
    if (task == NULL) {
        System_printf("Task_create() failed!\n");
        BIOS_exit(0);
    }

    BIOS_start();    /* does not return */
    return(0);
}

Board_Init API comes from the board library which is part of PDK. If you are runnning this on LCDK platform then, you need to add the following in your .cfg file.

var devType = "omapl138"

/* Load the OSAL package */
var osType = "tirtos"
var Osal = xdc.useModule('ti.osal.Settings');
Osal.osType = osType;
Osal.socType = devType;

/*use CSL package*/
var Csl = xdc.loadPackage('ti.csl');
Csl.Settings.deviceType = devType;

/* Load the Board package and set the board name */
var Board = xdc.loadPackage('ti.board');
Board.Settings.boardName = "lcdkOMAPL138";

Please note, before creating your examples refer to some of the PDK examples to understand how this works. to Create PDK driver examples, you need to run the pdkProjectCreate script as shown here:

Make sure that your PDK or Processor SDK RTOS build environment is setup before you run the Project create script.

Regards,

Rahul

Problem solved

i found your uart sample app.cfg.
