I tried it with both the NONOS sdk and the RTOS sdk, same problem. We also tried it with several different ESP breakout boards (for example the Adafruit Huzzah and others) and they all had the same problem.

Here is example code using the Sming framework:

Code:

#include <user_config.h>
#include <SmingCore.h>

Timer procTimer;

byte value;

void countdown()
{
   if (value == 0)
   {
      System.restart();
   }
   else
   {
      Serial.print("Restart in ");
      Serial.println(value--);
   }
}


void init()
{
   Serial.begin(SERIAL_BAUD_RATE); // 115200 by default
   Serial.systemDebugOutput(false); // Disable debug output

   value = 3;

   procTimer.initializeMs(1000, countdown).start();
}


Just in case the problem was in Sming, I also modified the example "blinky" app that just uses the ESP SDK, and it also has the same problem:

Code:

#include "ets_sys.h"
#include "osapi.h"
#include "gpio.h"
#include "os_type.h"
#include "user_config.h"

#define user_procTaskPrio        0
#define user_procTaskQueueLen    1
os_event_t    user_procTaskQueue[user_procTaskQueueLen];
static void user_procTask(os_event_t *events);

static volatile os_timer_t some_timer;

void some_timerfunc(void *arg)
{
    static int elapsed = 0;

    if (++elapsed == 3)
    {
       system_restart();
    }

    //Do blinky stuff
    if (GPIO_REG_READ(GPIO_OUT_ADDRESS) & BIT2)
    {
        //Set GPIO2 to LOW
        gpio_output_set(0, BIT2, BIT2, 0);
    }
    else
    {
        //Set GPIO2 to HIGH
        gpio_output_set(BIT2, 0, BIT2, 0);
    }
}

//Do nothing function
static void ICACHE_FLASH_ATTR
user_procTask(os_event_t *events)
{
    os_delay_us(10);
}

void ICACHE_FLASH_ATTR
user_init()
{
    // Initialize the GPIO subsystem.
    gpio_init();

    //Set GPIO2 to output mode
    PIN_FUNC_SELECT(PERIPHS_IO_MUX_GPIO2_U, FUNC_GPIO2);

    //Set GPIO2 low
    gpio_output_set(0, BIT2, BIT2, 0);

    //Disarm timer
    os_timer_disarm(&some_timer);

    //Setup timer
    os_timer_setfn(&some_timer, (os_timer_func_t *)some_timerfunc, NULL);

    //Arm the timer
    //&some_timer is the pointer
    //1000 is the fire time in ms
    //0 for once and 1 for repeating
    os_timer_arm(&some_timer, 1000, 1);

    //Start os task
    system_os_task(user_procTask, user_procTaskPrio,user_procTaskQueue, user_procTaskQueueLen);
}



Is this a known problem? Is there a solution to it?
