CCS设置Task问题

我在ccs中设置task

Task_Handle task;

Task_Params taskParams;

Task_Params_init(&taskParams);
    taskParams.stackSize=512;

    taskParams.priority=15;

    task = Task_create((Task_FuncPtr)taskFxn, &taskParams, &eb);

    //task = Task_create(taskFxn, NULL, &eb);

    if (task == NULL) {

        System_printf("Task_create() failed!\n");

        BIOS_exit(0);

    }

Debug时报错
