void wdtInitFxn()   
{  
  Watchdog_Params wp;  
  Watchdog_Handle watchdog;
  Watchdog_Params_init(&wp);  
  wp.callbackFxn    = wdtCallback;  
  wp.debugStallMode = Watchdog_DEBUG_STALL_ON;  
  wp.resetMode      = Watchdog_RESET_ON;  
   watchdog = Watchdog_open(Board_WATCHDOG0, &wp);  
  Watchdog_setReload(watchdog, 1000); // 1sec (WDT runs always at 48MHz/32)  
} 

运行这句的时候  Watchdog_setReload(watchdog, 1000); // 1sec (WDT runs always at 48MHz/32) 报The processor has escalated a configurable-priority exception to HardFault.   

Eggsy Pang：

Watchdog_setReload(watchdog, 1500000);这才是1s

150000 的时候也是一样 后来改成1000 还是这样

我这边是可以成功的：// Call watchdog init functionsWatchdog_init();Watchdog_Params params;params.callbackFxn= (Watchdog_Callback)watchdogCallback;params.resetMode= Watchdog_RESET_ON;params.debugStallMode = Watchdog_DEBUG_STALL_ON;watchdogHandle= Watchdog_open(Board_WATCHDOG0, &params);//1 seconds. Watchdog_setReload(watchdogHandle, 150000);

我这直接报异常

if (watchdog == NULL) {
return；}
加了一个判断 结果发现 watchdog 是NULL 没初始化成功

Eggsy Pang：

回复 user5159541:

你没有调用
Watchdog_init();

user5159541：

回复 Eggsy Pang:

void wdtInitFxn(){Watchdog_init();Watchdog_Params wp;Watchdog_Handle watchdog;Watchdog_Params_init(&wp);wp.callbackFxn= wdtCallback;wp.debugStallMode = Watchdog_DEBUG_STALL_OFF ;wp.resetMode= Watchdog_RESET_OFF;watchdog = Watchdog_open(Board_WATCHDOG0, &wp); if (watchdog == NULL) {return; }Watchdog_setReload(watchdog, 1500000); // 1sec (WDT runs always at 48MHz/32)}
结果还是一样

watchdog非空了 貌似 ok了 但是一初始化好以后，仿真器就不能工作了 ？是这样的吗？

user5159541：

回复 user5159541:

WATCHDOG已经可以工作了 但是出现新的问题 蓝牙在连接状态下会经常断开连接

Eggsy Pang：

回复 user5159541:

开门狗改大一点啊，连接需要时间啊 Watchdog_setReload(watchdog, 5*1500000); // 5sec
