RTOS/CC2640: How to set CC2640 watchdog with TIRTOS 2.13

Tool/software: TI-RTOS

Hi all:

Now I want to add watchdog to my project. When I delete the feed dog function，the program keep restart all the time, this looks like that my setting is success.

But when I add the feed dog function，program can only run the feed dog function even if I press the key over and over.

My own board uses CC26404*4 chip, and soft version is ble_sdk_2_02_01_18 and tirtos_simplelink_2_13_00_06.

My project is based on key_fob.

Here is  my operation steps.

1、add Watchdog.c、Watchdog.h、WatchdogCC26XX.c、WatchdogCC26XX.h in ble_sdk_2_02_01_18\src\components\services\src\watchdog .

2、add option include route:$SRC_BLE_CORE$/components/services/src/watchdog

3、add code

/////////////////////////////////CC2650DK_4SX.c     begin///////////////////////////////

#include "Watchdog.h"
#include "WatchdogCC26XX.h"

WatchdogCC26XX_Object watchdogCC26XXObjects[CC2650_WATCHDOGCOUNT];

const WatchdogCC26XX_HWAttrs watchdogCC26XXHwAttrs[] = {
{
.baseAddr = WDT_BASE,
.intNum = INT_NMI_FAULT,
//.intNum = INT_WDT_IRQ,
}
};

const Watchdog_Config Watchdog_config[] = {
{ &WatchdogCC26XX_fxnTable, &watchdogCC26XXObjects[0], &watchdogCC26XXHwAttrs[0] },
{ NULL, NULL, NULL },
};

/////////////////////////////////CC2650DK_4SX.c     end///////////////////////////////

/////////////////////////////////CC2650DK_4SX.h     begin///////////////////////////////

typedef enum CC2650_WatchdogName {
CC2650_WATCHDOG0 = 0,
CC2650_WATCHDOGCOUNT,
} CC2650_WatchdogName;

/////////////////////////////////CC2650DK_4SX.h     end///////////////////////////////

/////////////////////////////////keyfobdemo.c     begin///////////////////////////////

#include "Watchdog.h"
#include "WatchdogCC26XX.h"
#include <ti/drivers/power/PowerCC26XX.h>

...

void wdtCallback(UArg handle)
{
printS("wdtclear\r\n");
Watchdog_clear((Watchdog_Handle)handle);
//HAL_SYSTEM_RESET();
}

static Watchdog_Handle watchdog=NULL;

void wdtInitFxn()
{
//Board_initWatchdog();
Watchdog_Params wp;
Watchdog_Params_init(&wp);
wp.callbackFxn = wdtCallback;
wp.debugStallMode = Watchdog_DEBUG_STALL_ON;
wp.resetMode = Watchdog_RESET_ON;

watchdog = Watchdog_open(CC2650_WATCHDOG0, &wp);
Watchdog_setReload(watchdog, 3000000); // 1sec (WDT runs always at 48MHz/32)

}

static void KeyFobDemo_init(void)

{

wdtInitFxn();

}
