Hello,

I have a project which is using OTA and all was fine.
But I need to reinstall my computer and now, I have Arduino 1.6.12 and I update my esp8266 boradmanager.

Now i can't do any OTA update.
AFter a try, I need to erase the flash before downloding the sktech from Arduino IDE again.

I try on an ESP07 and an ESP12F.
My Flash configuration is 512k with 64ko SPIFFS

I validate the debug information on the ESP and I have this trace:

Then my ESP boot endlessly.

My sketch is based on the example ESP8266httpUpdate
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>
#include <ESP8266mDNS.h>
#include <ESP8266HTTPUpdateServer.h>

const char* host = "esp8266-webupdate";
const char* ssid = "XXXX";
const char* password = "YYYY";

ESP8266WebServer httpServer(80);
ESP8266HTTPUpdateServer httpUpdater;

void setup(void){

Serial.begin(74880);
Serial.println();
Serial.println("Booting Sketch...");

/*WiFi.softAPdisconnect(true);
WiFi.disconnect(true);
ESP.eraseConfig();
ESP.reset();*/

WiFi.mode(WIFI_AP_STA);
WiFi.begin(ssid, password);

while(WiFi.waitForConnectResult() != WL_CONNECTED){
WiFi.begin(ssid, password);
Serial.println("WiFi failed, retrying.");
}

Serial.print ("Connecté!\n adresse IP DHCP: " + WiFi.localIP().toString());

MDNS.begin(host);

httpUpdater.setup(&httpServer);
httpServer.begin();

MDNS.addService("http", "tcp", 80);
Serial.printf("HTTPUpdateServer ready! Open http://%s.local/update </br> http://%s/update in your browser\n", host, WiFi.localIP().toString().c_str());
}

void loop(void){
httpServer.handleClient();
}

Any idea will be welcome

Hello,

I looked on many websites and I found how to solve the problem.

It is very important o choose the right chip in Arduino IDE.

I don't remember what was my previous configuration around "Generic ESP8266 Module", but now I choose "WifInfo" and I define the Module as an ESP07 (1M/192K SPIFFS) and all works fine.
