TMS320C6748: Log_info无显示？

main文件代码：

#include <xdc/std.h>

#include <xdc/runtime/System.h>
#include <ti/sysbios/BIOS.h>

#include <xdc/runtime/Log.h>
#include <ti/sysbios/knl/Task.h>



/*
 *  ======== main ========
 */

void fun_task0(void);
void fun_task1(void);
Void main()
{ 
    System_printf("hello world\n");

    BIOS_start();
}

void fun_task0(void)
{
    Int count = 0;
    while(count<10)
    {
        Log_info1("Task0 is doing %d\n",count);
        Task_yield();
        count++;
    }
    BIOS_exit(0);
}

void fun_task1(void)
{
    Int count = 0;
    while(count<10)
    {
        Log_info1("Task1 is doing %d\n",count);
        Task_yield();
        count++;
    }
    BIOS_exit(0);
}

运行结果：

System_printf有结果，Log在printf窗口没有结果输出

请问有没有修改建议？
