Re: Enter Light Sleep Mode cause reset

I add code in the user init to check the reset reason,it seems the wdt cause the reset,how can I fix this?all the timers are already turn off.

Code:

   struct rst_info *rst_info = system_get_rst_info();
   os_printf("reset reason: %x\n", rst_info->reason);
   if(rst_info->reason == REASON_WDT_RST || rst_info->reason == REASON_EXCEPTION_RST || rst_info->reason == REASON_SOFT_WDT_RST)
   {
         if (rst_info->reason == REASON_EXCEPTION_RST)
         {
            os_printf("Fatal exception (%d):\n", rst_info->exccause);
         }
         os_printf("epc1=0x%08x, epc2=0x%08x, epc3=0x%08x, excvaddr=0x%08x, depc=0x%08x\n",rst_info->epc1, rst_info->epc2, rst_info->epc3, rst_info->excvaddr, rst_info->depc);
   }

Code:

reset reason: 3
epc1=0x40232284, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000

Code:

Enter Light Sleep Mode cause reset

2018-11-02T14:08:42+08:00

I'm trying out to enter light sleep mode in a timer interrupt function,but it will crash and reset as it do sleep sometimes.I found when it is in smart config mode ,it won't crash.If it's in station mode and connected to the AP,it will have this matter.Here is my code and log ,PLS help!! MY SDK version is NONOS 3.0.0

Code:

sleep_time_cnt: 60

enter sleep mode

wifi disconnected

pm close 7
fpm open,type:1 0
fpm 758

 ets Jan  8 2013,rst cause:2, boot mode:(3,6)

   wifi_set_opmode(STATION_MODE);

   wifi_station_get_config_default(&stationConf);

   if (os_strlen(stationConf.ssid) != 0) {
      os_printf("user_scan\n");
      //net_status   = 1;
      os_timer_disarm(&check_ip_timer);
      os_timer_setfn(&check_ip_timer, (os_timer_func_t *) user_check_ip, NULL);
      os_timer_arm(&check_ip_timer, 100, 0);

   } else {
