RTOS/CC1310: How to change WDT clock source

Hi Yama,

Are your device using low power modes? The watchdog timer will only run when the device is active; when going into standby mode, the watchdog clock will stop counting. This could be interpreted as the watchdog clock being "slower" while in reality, it simply stops counting when in standby.

The Watchdog timer clock source (or frequency) should not change depending on you using a debugger or not, using the debugger can however keep your device out of true standby.

Hi M-W
I don't use low power modes.
I write the program below. I use only one task.

__________________________________________________
Watchdog_Handle watchdogHandle;
volatile bool watchdogExpired;

void watchdogCallback(uintptr_t unused)
{
Watchdog_clear(watchdogHandle); /* Clear watchdog interrupt flag */
watchdogExpired = true;
}

int main(void)
{
Board_initGeneral();
Board_initUART();
Board_initWatchdog();
Board_initGPIO();
Board_initSPI();
dbgCnsl_open();

Watchdog_Params params;
Watchdog_init();
Watchdog_Params_init(&params);
params.callbackFxn = (Watchdog_Callback)watchdogCallback; /*!< Pointer to callback. Not supported on all targets. */
params.resetMode = Watchdog_RESET_ON; /*!< Mode to enable resets. Not supported on all targets. */
params.debugStallMode = Watchdog_DEBUG_STALL_ON; /*!< Mode to stall WDT at breakpoints. Not supported on all targets. */
watchdogHandle = Watchdog_open(Board_WATCHDOG0, &params);

Error_Block eb;
Error_init(&eb);

Task_Params_init(&u_task_params);
u_task_params.stackSize = MAIN_TASK_STACK_SIZE;
u_task_params.priority = MAIN_TASK_PRIORITY;
u_task_params.stack = &u_task_stack;
Task_construct(&u_task, MainCtrl_task, &u_task_params, &eb);

BIOS_start();
return 0;
}

void MainCtrl_task(UArg arg0, UArg arg1)
{
dbgCnsl_puts(PfStdout, "Main St\n");

for (int i=0; i<(40*60); ++i)
{
dbgCnsl_printf(PfStdout, "%d\n", WatchdogValueGet());
Task_sleep(100000); // 1sec
}
...........
}

Result with SmartRF06EBK is
__________________________________________________
Main St
89999660
88493518
86987527
85481341
83975356
...........
-------------------------------------------------------------------
89999660 - 88493518 = 1506142 : 1.5MHz


Result without SmartRF06EBK is
__________________________________________________
Main St
89999659
89862683
89861906
89861129
89860351
...........
-------------------------------------------------------------------
89999659 - 89862683 = 136976
89862683 - 89861906 = 777
89861906 - 89861129 = 777
The result of this time is from 777Hz to 136976Hz.

How can I change the above program?
