TC397 CPU看门狗二次复位后，一直处于复位状态不再重启是什么原因导致的？

请问TC397 CPU看门狗二次复位后，一直处于复位状态，不再重启。这是什么原因导致的？ /* !!WATCHDOG0 AND SAFETY WATCHDOG ARE DISABLED HERE!! * Enable the watchdogs and service them periodically if it is required */ // //IfxScuWdt_disableCpuWatchdog(IfxScuWdt_getCpuWatchdogPassword()); IfxScuWdt_disableSafetyWatchdog(IfxScuWdt_getSafetyWatchdogPassword()); IfxScuWdt_changeCpuWatchdogReload(IfxScuWdt_getCpuWatchdogPassword(), REL_VAL); IfxScuWdt_serviceCpuWatchdog(IfxScuWdt_getCpuWatchdogPassword()); /* Wait for CPU sync event */ IfxCpu_emitEvent( g_cpuSyncEvent); IfxCpu_waitEvent( g_cpuSyncEvent, 1);
