#25656 I solved the problem with flashing, just updated to newest SDK and evertyhing is flashing without errors.
The problem is esp8266 reseting every 3 seconds. I tried esp-01 and esp-12, same issue.
This is just blink example...

Code: Select all/*
   The obligatory blinky demo
   Blink an LED on GPIO pin 2
*/

#include <ets_sys.h>
#include <osapi.h>
#include <gpio.h>

// see eagle_soc.h for these definitions
#define LED_GPIO 2
#define LED_GPIO_MUX PERIPHS_IO_MUX_GPIO2_U
#define LED_GPIO_FUNC FUNC_GPIO2

#define DELAY 500000 /* microseconds */

extern void ets_wdt_enable (void);
extern void ets_wdt_disable (void);

void user_rf_pre_init(void)
{
}

void user_init(void)
{
   uint8_t state=0;
   ets_wdt_enable();
   ets_wdt_disable();
   // Configure pin as a GPIO
   PIN_FUNC_SELECT(LED_GPIO_MUX, LED_GPIO_FUNC);
   for(;;)
   {
      GPIO_OUTPUT_SET(LED_GPIO, state);
      os_delay_us(DELAY);
      state ^=1;
   }
}


and a makefile, I changed baud, port and mode to DIO, just like in Arduino esp8266. I also tried to enable/disable wdt in code.

#27567 Hi All

A new version of my build Espressif DevKit for Windows v2.0.8
The list of changes to the first page

Update procedure:
1. Remove the old version.
2. Install the new version DevKit.
ATTENTION!!! When you delete the old version will be removed entire directory C:\Espressif
