RTOS/CC2640R2F: task creation fail question

Part Number: CC2640R2F

Tool/software: TI-RTOS

Hi, 

I am trying to create an individual task in the simple_peripheral project. so I created two files called: blink.c and blink.h under Application folder, in my blink.c, I have:

#include <string.h>

#include <ti/sysbios/knl/Task.h>
#include <ti/sysbios/knl/Clock.h>
#include <ti/sysbios/knl/Event.h>
#include <ti/sysbios/knl/Queue.h>

#include <ti/drivers/GPIO.h>

#include "board.h"
#include "blink.h"

// Task configuration
#define BLK_TASK_PRIORITY                     1

#ifndef BLK_TASK_STACK_SIZE
#define BLK_TASK_STACK_SIZE                   128
#endif

// Task configuration
Task_Struct blkTask;
Char blkTaskStack[BLK_TASK_STACK_SIZE];


static void blinkled_taskFxn(UArg a0, UArg a1);

void blinkled_createTask(void)
{
  Task_Params taskParams;

  // Configure task
  Task_Params_init(&taskParams);
  taskParams.stack = blkTaskStack;
  taskParams.stackSize = BLK_TASK_STACK_SIZE;
  taskParams.priority = BLK_TASK_PRIORITY;

  Task_construct(&blkTask, blinkled_taskFxn, &taskParams, NULL);
}



static void blinkled_taskFxn(UArg a0, UArg a1)
{
    // Testing Codes
    GPIO_init();
    GPIO_write(Board_GPIO_LED1, Board_GPIO_LED_ON);
}

and in blink.h, I have:


#ifndef BLINK_H #define BLINK_H #ifdef __cplusplus extern "C" { #endif extern void blinkled_createTask(void); /********************************************************************* *********************************************************************/ #ifdef __cplusplus } #endif #endif

basically, I just followed simple_peripheral.c kind of style. and in main.c, I call blinkled_createTask();, expecting this code would live in the project. but when I compile it, it thrown an error says:

error: symbol "blinkled_createTask" redeclared with incompatible type:
"int [ExplSign]()"
in "../Startup/main.c" at line 220 and:
"void()"
in "../Application/blink.c" at line 27)

any help would be great!
