Enter Light Sleep Mode cause reset

[JacksonLv]

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: Select all

sleep_time_cnt: 60

enter sleep mode

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: Select all

   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);
   }
