Hi guys

I am new on esp8266. I am trying to realize a simple meto station with Arduino and this shield:
ESP8266-Web-Server-Port-WiFi-Expansion-Board-ESP-13-Compatible-With-Arduino-p-1008124.html?rmmds=myorderIf
I installed into Arduino IDE the support for esp8266. If I try to load on the board with Arduino IDE an example sketch, for example the blink:


ESP8266 Blink by Simon Peter
Blink the blue LED on the ESP-01 module
This example code is in the public domain

The blue LED on the ESP-01 module is connected to GPIO1
(which is also the TXD pin; so we cannot use Serial.print() at the same time)

void setup() {
pinMode(LED_BUILTIN, OUTPUT); // Initialize the LED_BUILTIN pin as an output
}

// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, LOW); // Turn the LED on (Note that LOW is the voltage level
// but actually the LED is on; this is because
// it is acive low on the ESP-01)
delay(1000); // Wait for a second
digitalWrite(LED_BUILTIN, HIGH); // Turn the LED off by making the voltage HIGH
delay(2000); // Wait for two seconds (to demonstrate the active low LED)
}


I have the errors:
warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed

reading some tutorial on posts it seems is a firmware problem. So I try to flash a new firmware following this tutorial:
micropython-basics-how-to-load-micropython-on-a-board/serial-terminal?view=all
but I receive the error:

A fatal error occurred: Failed to connect to ESP8266
Can someone help me to solve this problem?


Thanks.

I didn't find the right solution from the Internet.
