OTEthernet example works?

[imskanti]

No its not

[JAndrassy]

do you use my_boards or MegaCore? did you burn the Optiboot bootloader?

[imskanti]

yes im using my_boards. burnt the Arduino mega 2560(optiboot) in my boards

[JAndrassy]

can you try to upload with 'fake programmer'?
https://github.com/jandrassy/ArduinoOTA#ota-upload-from-ide-without-network-port

[imskanti]

I HAVE TRIED BOTH OF THE METHODES.

[imskanti]

As per my understanding its a issue with the bootloader, because connecting to board ... done , uploading sketch ... done but its not flashing.

i have tried arduino mega bootloader as well as your bootloader(optiboot) in both condition its same problem.

[JAndrassy]

why did you try with the Mega bootloader? it doesn't make sense to try it with that.
Are you sure the Optiboot is successfully flashed?
the response sent to upload tool is before the uploaded sketch is applied so there is no way to report an error with flashing. it is just the upload tool's generic message.

[imskanti]

im sure Optiboot is flashed.
im using arduino as isp to upload the bootloader is there any problem?

[JAndrassy]

im using arduino as isp to upload the bootloade

me too. it is ok

[imskanti]

please help im stuck in the situation

can you give me the step by step check points

[JAndrassy]

I've seen this error too in some case, which I can't remember what it was or it go away before I could determine it.. The error is strange because checking the upload tool's source code I see that it prints "Error flashing the sketch" only once.

can you show me the upload with the 'fake programmer'?

[JAndrassy]

I would expect it to use the arduinoOTA tool in my_boards/tools since the platform.txt file has
tools.arduinoOTA.cmd={runtime.hardware.path}/tools/arduinoOTA

[imskanti]

can you please clarify i did'nt got your point.

[JAndrassy]

upload with fake programmer with current version of my_boards should use
C:\Users\skant\Documents\Arduino\hardware\my_boards\tools\arduinoOTA
but your has
C:\Users\skant\AppData\Local\Arduino15\packages\arduino\tools\arduinoOTA\1.2.1/bin/arduinoOTA

Hi , let me follow up here with this topic, I have same issues with my OTA/WIFI combination,
sometimes its working, sometimes not... (using Programmer, Serial monitor is closed, no Web Server Access in parallel

If I repeat it several times it is somewhen working again...
I am using some interrupts, tried to deactivate them, but even worse... so deleted the change again
cli();
ArduinoOTA.poll();
sei();

[JAndrassy]

Mega with Ethernet library?

[Bordman-ger]

WeMOS Mega + WiFi R3 ATmega2560 + ESP8266 with WIFIESPAT

[JAndrassy]

the SerialWiFiOTA example works?

[Bordman-ger]

Yes everything is working, also OTA Updates works sometimes... b

[JAndrassy]

didn't we already solve this?
JAndrassy/WiFiEspAT#97

[Bordman-ger]

no, we fixed that both is working in general in parallel . yes that is fixed...
but Time by Time its not working... fix is still implemented...

Shall I stop the Web server and check if issue is gone? I will do ...

[Bordman-ger]

4 times it worked, 5th time is failing again, Web server is off... so seem to be an other issue?
// start WEB Server
// server.begin();
and
// webserver();

[JAndrassy]

how large is the sketch? what is the baud rate for AT?
do you have verbose mode for upload set in IDE preferences? it should print the cause of the upload error.
btw. don't turn off interrupts. Serial will not work efficient without interrupts

[Bordman-ger]

Size: 38798 Bytes (14%)
#define AT_BAUD_RATE 250000
Serial3.begin(AT_BAUD_RATE);
WiFi.init(&Serial3);

Verbose is active for Upload only:

About the Interrupts: I have set 4 different interupts and I am using Serial1 in parallel - might this be a problem?
Wifi is connected to Serial3

[JAndrassy]

to debug you can add in WiFiOTA.cpp to sendHttpResponse

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

[JAndrassy]

does the upload tool (arduinoOTA) time out (30 seconds)?

[Bordman-ger]

yes it looks like this is a timeout
I was also able to run the update with this output after exactly 30 seconds...
Connecting to board ... done
Uploading sketch ... done
Flashing sketch ... done
Error flashing the sketch
Error flashing the sketch

The update takes fifferent lenght, 20/25/17/30/19/26/18/24 20/15/27/25/30 seconds after last output...

so two times it timed out... and i got the error message this will also explain why its failing mor often if a client is connected to the Web server in parallel

[JAndrassy]

has the esp8266 a good WiFi signal? 38798 bytes large bin shouldn't need 30 seconds

[Bordman-ger]

I think its good... -44dB
the first two steps take less than one second...
Connecting to board ... done
Uploading sketch ... done

I startet the stop watch after "Flashing sketch ..." is shown...

[JAndrassy]

try longer timeout
-t parameter in platform.local.txt

if the upload is stable and only needs more time, then it should help

[Bordman-ger]

too easy (-: but it looks much better now.. I will keep watching - also running Webserver in parallel is okay...

[JAndrassy]

ArduinoOTA does flashing while it receives the uploaded data. so those are not two separate steps.

[Bordman-ger]

update: its now working fine...
setup: Client connected to the Webserver, in parallel OTA Update is done with WIFI, -47 dB connection...
I had only one issue today: after updating okay, the board was not longer reachable, after reboot it was okay... so maybe a reset issue??? but only 5% of updates will fail in this way...
Yesterday I had the situation tha the RX led was flassing but board was also not reachable - not with OTA, not with web client...
after reset it worked fine again...
I will pusht the board to the attic now - WIFI will be worse, we will see...

And please add this two in one board to the "working boards" list... clone of:WeMOS Mega + WiFi R3 ATmega2560 + ESP8266

and as promised I will work on a quick start guide...

Hi, I have the same board as @Bordman-ger and the same issue with large sketches. Could you provide more detail on setting an increased timeout? -t isn't a valid arg for my ArduinoOTA.exe (ver 1.3.0). Thanks

my build of the arduinoOTA in my_boards already has the -t parameter

[megacct]

Thanks. Hadn't spotted the newer version. -t option with this new version of the tool sorted my problem.
