我试图从Arduino IDE将代码上传到esp8266，它给了我这个错误：

我在Arduino IDE上安装了esp8266扩展板，并将其设置为'Generic ESP8266 Module'。我尝试更改上传速度，但仍然失败。这是我使用的代码：
#include <ESP8266WiFi.h>
const char* ssid = "SSID";//type your ssid
const char* password = "PASSWORD";//type your password
int ledPin = 2; // GPIO2 of ESP8266
WiFiServer server(80);
void setup() {
Serial.begin(115200);
delay(10);
pinMode(ledPin, OUTPUT);
digitalWrite(ledPin, LOW);
// Connect to WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
// Start the server
server.begin();
Serial.println("Server started");
// Print the IP address
Serial.print("Use this URL to connect: ");
Serial.print("http://");
Serial.print(WiFi.localIP());
Serial.println("/");
}
void loop() {
// Check if a client has connected
WiFiClient client = server.available();
if (!client) {
return;
}
// Wait until the client sends some data
Serial.println("new client");
while(!client.available()){
delay(1);
}
// Read the first line of the request
String request = client.readStringUntil('\r');
Serial.println(request);
client.flush();
// Match the request
int value = LOW;
if (request.indexOf("/LED=ON") != -1) {
digitalWrite(ledPin, HIGH);
value = HIGH;
}
if (request.indexOf("/LED=OFF") != -1){
digitalWrite(ledPin, LOW);
value = LOW;
}
// Set ledPin according to the request
//digitalWrite(ledPin, value);
// Return the response
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println(""); // do not forget this one
client.println("<!DOCTYPE HTML>");
client.println("<html>");
client.print("Led pin is now: ");
if(value == HIGH) {
client.print("On");
} else {
client.print("Off");
}
client.println("<br><br>");
client.println("Click <a href=\"/LED=ON\">here</a> turn the LED on pin 2 ON<br>");
client.println("Click <a href=\"/LED=OFF\">here</a> turn the LED on pin 2 OFF<br>");
client.println("</html>");
delay(1);
Serial.println("Client disonnected");
Serial.println("");
}
（我已经更改了SSID和密码值）我已经搜索了所有可以找到的网站，但仍然无法修复。 esp8266处于闪存模式。另外，我知道esp8266没有损坏。我将不胜感激。
您可以发布上传设置吗？
可能出问题的地方：
您可能有一个NODEMCU模块，请尝试在上传设置中切换到该板。
您是否在插入ESP时确认出现新的COM端口？
您是否选择了正确的COM端口？
这些是我的ESP8266设置，here
如果您实际上有一个NODEMCU，如果上面没有任何作用，请尝试使用所有这些说明来更新固件：https://github.com/nodemcu/nodemcu-firmware
