Hello,I have a problem while I try to write the program into flash by OTA about arduinoota HOT 14 CLOSED

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

from arduinoota.

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:

from arduinoota.

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

from arduinoota.

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

from arduinoota.

and is the new sketch uploaded over OTA running?

from arduinoota.

I remember it doesn't work.

from arduinoota.

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

from arduinoota.

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.

from arduinoota.

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

from arduinoota.

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?

from arduinoota.

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)

from arduinoota.

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

from arduinoota.

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

from arduinoota.

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

from arduinoota.
