Dear Friends,

Now i am working with CC3220SF evaluation kit, i wan't to add watch dog code to my base code,i was trying to create a code for CC3220SF in past 15 days but i get errors so  i am trying in multiple examples like
https://forum.43oh.com/topic/9346-cc3200-watchdog/
https://forum.43oh.com/topic/11170-watchdog-in-cc3200/

these examples does not work for my CC3220SF because these examples are support only CC3200 boards, i don't know how to create watchdog header's for CC3220SF, can you please help me to find the correct example for CC3220SF.

SInce no other responses have come along, I will get the ball rolling by asking for a bit more detail.

What errors are you getting?

What are you trying to do with the watchdog?

As far as I know (not using the CC32XX series), Energia supports the 3220 launchpad board. See https://forum.43oh.com/topic/13311-connecting-cc3220sf-to-cayenne-mqtt-using-energia/ (Rei Vilo's msg: 6th in the thread)

Dear friend,

thanks for your reply, i just use the watch dog for reset my CC3220SF when that is struck or not working well, this is code what i am trying to compile  

//#include <stdlib.h>
#include "inc/hw_types.h"
#include "inc/hw_wdt.h"
#include "driverlib/wdt.h"

typedef void (*fAPPWDTDevCallbk)();

void setup() {
  boolean bRetcode;
  Serial.begin(115200);
  Serial.println("**************************************************");
  Serial.println("*             CC3200 Watchdog Test               *");
  Serial.println("**************************************************");

  //
  // Set up the watchdog interrupt handler.
  //
  WDT_IF_Init(WatchdogIntHandler, MILLISECONDS_TO_TICKS(WD_PERIOD_MS));

  bRetcode = MAP_WatchdogRunning(WDT_BASE);
  if (!bRetcode)
  {
    Serial.println("Watchdog failed to run. Shutting down");
    WDT_IF_DeInit();
    while (1);
  }
}

void loop() {
  Serial.print("Watchdog interrupt count: ");
  Serial.println(g_ulWatchdogCycles);
  delay(1000);
}

void WatchdogIntHandler(void)
{
  //
  // After 10 interrupts, switch On LED6 to indicate system reset
  // and don't clear watchdog interrupt which causes system reset
  //
  if (g_ulWatchdogCycles >= 10)
  {
    MAP_UtilsDelay(800000);
    return;
  }
  //
  // Clear the watchdog interrupt.
  //
  MAP_WatchdogIntClear(WDT_BASE);
  //
  // Increment our interrupt counter.
  //
  g_ulWatchdogCycles++;

}

void WDT_IF_Init(fAPPWDTDevCallbk fpAppWDTCB, unsigned int uiReloadVal)
{
  //
  // Enable the peripherals used by this example.
  //
  MAP_PRCMPeripheralClkEnable(PRCM_WDT, PRCM_RUN_MODE_CLK);
  //
  // Unlock to be able to configure the registers
  //
  MAP_WatchdogUnlock(WDT_BASE);

  if (fpAppWDTCB != NULL)
  {
    MAP_IntPrioritySet(INT_WDT, INT_PRIORITY_LVL_1);
    MAP_WatchdogIntRegister(WDT_BASE, fpAppWDTCB);
  }
  //
  // Set the watchdog timer reload value
  //
  MAP_WatchdogReloadSet(WDT_BASE, uiReloadVal);
  //
  // Start the timer. Once the timer is started, it cannot be disable.
  //
  MAP_WatchdogEnable(WDT_BASE);
}

void WDT_IF_DeInit()
{
  //
  // Unlock to be able to configure the registers
  //
  MAP_WatchdogUnlock(WDT_BASE);
  //
  // Disable stalling of the watchdog timer during debug events
  //
  MAP_WatchdogStallDisable(WDT_BASE);
  //
  // Clear the interrupt
  //
  MAP_WatchdogIntClear(WDT_BASE);
  //
  // Unregister the interrupt
  //
  MAP_WatchdogIntUnregister(WDT_BASE);
}

 

if i choose board cc3200 this code compiled with out error but if i choose cc3220SF i get these errors,

Dear friends,

this is my new code and also i get some error, anybody can help me to find the solution for this ,

#include <stdlib.h>
#include "inc/hw_types.h"
#include "inc/hw_wdt.h"
#include "driverlib/wdt.h"
#include "driverlib/utils.h"

#include <ti/devices/cc32xx/driverlib/wdt.h>
#include <ti/drivers/watchdog/WatchdogCC32XX.h>
#include <ti/drivers/Watchdog.h>

unsigned long count;
//uint_least8_t WDT_BASE;
void setup()
{

  Serial.begin(115200);
  Serial.println("*             CC3220 Watchdog Test               *");
  
  Watchdog_Handle handle;
  Watchdog_Params params;
  uint32_t tickValue;

  Watchdog_init();

  Watchdog_Params_init(&params);
  params.resetMode = Watchdog_RESET_ON;
  params.callbackFxn = watchdogCallback;
  //handle = Watchdog_open(Watchdog_configIndex, &params);
  
  handle = Watchdog_open(Board_WATCHDOG, &params);
  if (handle == NULL) 
  {
    Serial.println("*             Error opening watchdog               *");
  }
  // Set timeout period to 100 ms
  tickValue = Watchdog_convertMsToTicks(handle, 100);
  Watchdog_setReload(handle, tickValue);
}

void loop()
{
  Serial.print("Watchdog interrupt count: ");
  Serial.println(count);
  delay(1000);

}
void watchdogCallback(UArg handle)
{
  //Watchdog_clear(handle);
  Serial.print("Watchdog: ");
  Serial.println(count);
}

Dear kannan,

try this code it's working fine with cc3220sf, this code reset your device when Cycles increase greater than 10, 

#include <stdio.h>
#include <stdint.h>
#include <inc/hw_types.h>
#include <inc/hw_ints.h>
#include <inc/hw_memmap.h>
#include <driverlib/prcm.h>
#include <driverlib/wdt.h>
#include <driverlib/rom.h>
#include <driverlib/rom_map.h>
#include <driverlib/interrupt.h>
 

volatile unsigned long Cycles;
#define WD_PERIOD_MS                 1000
#define MAP_SysCtlClockGet           80000000

#define MILLISECONDS_TO_TICKS(ms)    ((MAP_SysCtlClockGet / 1000) * (ms))

void setup()
{
      Serial.begin(115200);
      Serial.println("Watchdog Test");
    MAP_PRCMPeripheralClkEnable(PRCM_WDT, PRCM_RUN_MODE_CLK);
    MAP_WatchdogUnlock(WDT_BASE);
    MAP_IntPrioritySet(INT_WDT, INT_PRIORITY_LVL_1);
    MAP_WatchdogIntRegister(WDT_BASE,&WatchdogIntHandler);
    MAP_WatchdogReloadSet(WDT_BASE,MILLISECONDS_TO_TICKS(WD_PERIOD_MS));
    MAP_WatchdogEnable(WDT_BASE);
}

void loop()
{
  Serial.println("Watchdog Reset test");

 delay(2000);
}


void WatchdogIntHandler(void)
{
    Serial.println("Watch rest");
    Serial.println(Cycles);
    if(Cycles>=10)
    {
      Serial.println("Reseting..........");
      return;
    }
    MAP_WatchdogIntClear(WDT_BASE);
    Cycles++;

}
