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.

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 functions
Watchdog_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);

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

你没有调用
Watchdog_init();

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？

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

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

0 user5159541 6 年多前回复 Eggsy Pang

Watchdog_setReload(watchdog, 10*1500000); // 10sec (WDT runs always at 48MHz/32) 已经改10秒了

中断有没有清除标志位

void wdtCallback(UArg handle)
{
Watchdog_clear((Watchdog_Handle)handle);
}
回调函数里处理了

您可以试一下使用如下代码

void Watchdog_Init(void)
{
    Watchdog_Params params;    
        
    Watchdog_init();
    
    Watchdog_Params_init(&params);
    params.resetMode = Watchdog_RESET_ON;
    WatchdogHandle = Watchdog_open(Board_WATCHDOG0, &params);
        
    if (WatchdogHandle == NULL) {
        /* Error opening Watchdog */
        while (1);
    }
}

基于哪个例程？断开连接输出什么串口信息呢
