hardware： CC2650_LaunchPad

TI-RTOS：2.20

define xPOWER_SAVING

I user the watchdog driver, this is my code

static Watchdog_Handle hWDT=NULL;

void watchdogCallback(UArg handle)
{
    Watchdog_clear(hWDT);
}

void watchdog_init()
{
    // open watchdog
    Watchdog_init();
    Watchdog_Params wdParams;
    uint32_t tickValue;

    Watchdog_Params_init(&wdParams);
    wdParams.resetMode = Watchdog_RESET_ON;
    wdParams.debugStallMode = Watchdog_DEBUG_STALL_OFF;
    wdParams.callbackFxn = watchdogCallback;
    hWDT = Watchdog_open(Board_WATCHDOG, &wdParams);
    // set timeout period to 100 ms
    tickValue = Watchdog_convertMsToTicks(hWDT, 2000);
    Watchdog_setReload(hWDT, tickValue);
}

but the device will restart once every 4 seconds.

Look callback function no execution.

Did you implement all the needed HW_attribute in your board.c/.h? Those have been missing in Ti-RTOS 2.20 and the upcoming TI-RTOS has it fixed.

thanks you answer：

Yes，I add the HW_attribute.

current the watchdog is working. because the device will reset。

My problem is the callback function not execute。

/*
 *  ============================= Watchdog begin =====================================
*/

/* Include drivers */
#include <ti/drivers/Watchdog.h>
#include <ti/drivers/watchdog/WatchdogCC26XX.h>

WatchdogCC26XX_Object wdCC26XXObject[CC2650_LAUNCHXL_WATCHDOGCOUNT];

/* Generic Watchdog instance identifiers */
#ifndef  WDT_RELOAD_VALUE_MS
#define WDT_RELOAD_VALUE_MS             5000
#endif


const WatchdogCC26XX_HWAttrs wdCC26XXHWAttrs[CC2650_LAUNCHXL_WATCHDOGCOUNT] = {
    {
        .baseAddr = WDT_BASE,           /*!< Base adddress for Watchdog */
        .intNum   = INT_WDT_IRQ,         /*!< Watchdog interrupt number */
        .reloadValue= WDT_RELOAD_VALUE_MS,   /*!< Reload value in milliseconds for Watchdog */
    },
};

/* Watchdog configuration structure */
const Watchdog_Config Watchdog_config[CC2650_LAUNCHXL_WATCHDOGCOUNT+1] = {
    {
        .fxnTablePtr = &WatchdogCC26XX_fxnTable,
        .object  = &wdCC26XXObject,
        .hwAttrs = &wdCC26XXHWAttrs
    },
    {NULL, NULL, NULL},
};

I need help，everybody who knows?

the interrupt number used in TI-RTOS watchdog driver is INT_NMI_FAULT.

Change .intNum = INT_WDT_IRQ, to .intNum = INT_NMI_FAULT,

Then it should work for you too. I just tried it on my setup. It resets in 2 seconds after loading the value.

I have changed.

but the device is dead.

not working and don't restart.

What do you mean by the device is dead? How do you verify is watch dog reset has performed? do you toggle an IO?
Also when performing watchdog reset, please disconnect JTAG, or else, the device will enter Halt in Boot once it resets.

yes, device is dead.

no, i use uart print log.

I use the cc2650_LaunchPad, i disconnect the TMS, TCK,TDI,TDO,SWO. and reset the device，but still dead.

Is there anything else need to be aware of?

Can you program the device with different example to check if it's actually not functioning?
If launchpad is still not running after programming with other example project, please perform HW debug

the device is ok.
when i delete the watchdog code, is working normal.

Can you make it to run with the code I provided? Do you still have problem performing watchdog?
