Hello,I have a problem while I try to write the program into flash by OTA

[TimeBather]

Log: C:\Program Files (x86)\Arduino\hardware\tools\avr/bin/arduinoOTA -address 192.168.0.170 -port 65280 -username arduino -password password -sketch C:\Users\DELL\AppData\Local\Temp\arduino_build_272676/ArduinoOTA1.ino.bin -upload /sketch -b Connecting to board ... done Uploading sketch ... done Flashing sketch ... Error flashing the sketch Error flashing the sketch

Why did it happend and how can I resolve it?I try to find Baidu and Google but there is no solution.

I'm using Arduino MEGA2560&Arduino Ethernet Shield. The version of IDE:Arduino 1.8.10 The source code:

#include <EEPROM.h>

/*

 This example polls for sketch updates over Ethernet, sketches
 can be updated by selecting a network port from within
 the Arduino IDE: Tools -> Port -> Network Ports ...

 Circuit:
 * W5100, W5200 or W5500 Ethernet shield attached

#include <SPI.h>
#include <Ethernet.h>
#include <ArduinoOTA.h>
//#define Serial SerialUSB
IPAddress ip(192, 168, 0, 170);
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, ip[2], ip[3] };
void setup() {
  pinMode(LED_BUILTIN, OUTPUT);
  Serial.begin(115200);
  //while (!Serial);  // only needed for Leo?
  Serial.print("\n\nVer: 2\nReboots: ");
  int reboots;
  EEPROM.get(1, reboots);
  reboots++;
  EEPROM.put(1, reboots);
  Serial.println(reboots);

  // start the Ethernet connection:
  Serial.println("Initialize Ethernet");
  Ethernet.begin(mac, ip);
  Serial.println(Ethernet.localIP());
  // start the OTEthernet library with internal (flash) based storage
  ArduinoOTA.begin(Ethernet.localIP(), "Arduino","password", InternalStorage);
}

void loop() {
  // check for updates
  ArduinoOTA.poll();

  // add your normal loop code below ...
} 

Then,I change the configure from "arduino" to "Arduino":

Connecting to board ...  done
Uploading sketch ...  done
Flashing sketch ...  done
Error flashing the sketch:
Error flashing the sketch:

I have never seen "Error flashing the sketch:" with :. What does print it? With "Flashing sketch ... done" arduinoOTA tool is done.

[TimeBather]

It print nothing.So I can't get any infomation from them. I copyed all of the error log.

[TimeBather]

I used the Example OTA 'programmer' configuration in programmers.txt and copied The context of '/extras/avr/plantform.local.txt' to 'plantform.txt'

[JAndrassy]

and is the new sketch uploaded over OTA running?

[TimeBather]

I remember it doesn't work.

[TimeBather]

I will try again after I get home.It may take me about half an hour.

[JAndrassy]

after "Flashing sketch ... done" the sketch is uploaded and applied and the arduinoOTA tool finished The "Error flashing the sketch:" is a mystery.

Add in WiFiOTA.cpp to sendHttpResponse

  Serial.print("OTA upload response: ");
  Serial.println(status);

to see if the upload was successful.

[TimeBather]

It doesn't work.I found there is nothing except the network Infomation(IP Address and so on)

[JAndrassy]

It doesn't work.I found there is nothing except the network Infomation(IP Address and so on)

did you add the Serial.println(status); and it doesn't print anything?

[TimeBather]

It doesn't work.I found there is nothing except the network Infomation(IP Address and so on)

did you add the Serial.println(status); and it doesn't print anything?

Yes,I upload them by OTA but nothing displayed except network infomation.But it displayed if I upload by Serial Port(USB)

[JAndrassy]

did you add the print to WiFiOTA.cpp in the library in sendHttpResponse function?

[TimeBather]

Ok,I will add it and test the sketch later.

[JAndrassy]

so the "Error flashing the sketch:" is printed if IDE upload verbose mode is enabled. with ArduinoOTA 1.0.4 version the fail reason is printed after the semicolon
