not working with Ethernet library

[miksumin]

It seems it is not working properly with Ethernet library I am using MegaCore with EthernetENC library on ATmega2561 with ENC28j60 chip

Everything done as you wrote in OTA Upload from IDE without 'network port' IDE output: Connecting to board ... done Uploading sketch ... done Flashing sketch ... Error flashing the sketch Flashing sketch ... Error flashing the sketch

[JAndrassy]

try this Connect the board to computer and add in WiFiOTA.cpp to sendHttpResponse

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

to see the response message.

[miksumin]

OTA upload response: Unauthorized

[miksumin]

Using as in example: ArduinoOTA.begin(Ethernet.localIP(), "Arduino", "password", InternalStorage);

[JAndrassy]

did you copy extras/avr/platform.local.txt to MegaCore? the upload over 'programmer' has the password in upload command in platform.local.txt

[miksumin]

Have copied the content of extras/avr/platform.local.txt to MegaCore platform.txt file. It contains the following:

This configuration file supports the general ArduinoOTA library https://github.com/jandrassy/ArduinoOTA

Create output (bin file)

recipe.objcopy.bin.pattern="{compiler.path}{compiler.elf2hex.cmd}" -O binary {compiler.elf2hex.extra_flags} "{build.path}/{build.project_name}.elf" "{build.path}/{build.project_name}.bin" tools.avrdude.network_cmd={runtime.tools.arduinoOTA.path}/bin/arduinoOTA tools.avrdude.upload.network_pattern="{network_cmd}" -address {serial.port} -port 65280 -username arduino -password "{network.password}" -sketch "{build.path}/{build.project_name}.bin" -upload /sketch -b

arduinoOTA as programmer. add entries with {ip} into programmers.txt

tools.arduinoOTA.cmd={runtime.tools.arduinoOTA.path}/bin/arduinoOTA tools.arduinoOTA.program.params.verbose= tools.arduinoOTA.program.params.quiet= tools.arduinoOTA.program.pattern="{cmd}" -address {ip} -port 65280 -username arduino -password password -sketch "{build.path}/{build.project_name}.bin" -upload /sketch -b

So where is the password?

[miksumin]

Also tried to copy file platform.local.txt to MegaCore directory and got the following: Connecting to board ... done Uploading sketch ... done An error occurred while uploading the sketch Flashing sketch ... Error flashing the sketch

[miksumin]

Please help

[JAndrassy]

still "OTA upload response: Unauthorized"?

set the IDE in Preferences to upload verbose mode and then post here the upload command

[miksumin]

upload verbose mode in IDE is set and the output I posted above: Connecting to board ... done Uploading sketch ... done An error occurred while uploading the sketch Flashing sketch ... Error flashing the sketch

[miksumin]

upload command: ...\AppData\Local\Arduino15\packages\arduino\tools\arduinoOTA\1.3.0/bin/arduinoOTA -address 192.168.0.125 -port 65280 -username arduino -password password -sketch ...\AppData\Local\Temp\arduino_build_123594/MegaD-2561.ino.bin -upload /sketch -b

[miksumin]

So what I'm doing wrong or what is going wrong in my case?

[JAndrassy]

still "OTA upload response: Unauthorized"?

[miksumin]

Did you read my previous posts?

[JAndrassy]

Did you read my previous posts?

yes. upload command is ok. does WiFIOTA always print Unauthorized?

[miksumin]

WiFIOTA gives nothing output

[JAndrassy]

you use OTEthernet example without changes?

[miksumin]

Yes, the code is identical OTEthernet example

[JAndrassy]

it is strange that it continues with "Flashing sketch" after "An error occurred while uploading the sketch". add some additional output to the OTA uploaded sketch to see if it is applied.

[miksumin]

Sketch is not starting after the above OTA upload error

[JAndrassy]

did you burn Optiboot from current version of MegaCore?

[miksumin]

I have to use existing bootloader

[JAndrassy]

I have to use existing bootloader

Optoboot with copy_flash_pages function is requirement.

[miksumin]

How I can burn Optiboot?

[JAndrassy]

How I can burn Optiboot?

with AVR hardware programmer or https://www.arduino.cc/en/Tutorial/BuiltInExamples/ArduinoISP

[miksumin]

Tried to burn Optiboot using FT232R USB UART connected to ATmega2561 SPI without success:

     Programmer Type : ftdi_ft2xx
     Description     : Arduino: FT232R connected to ISP
     Pin assignment: 0..7 = DBUS0..7

Me be you can help me find a way to solve this?

Tried to burn Optiboot using FT232R USB UART connected to ATmega2561 SPI without success:

You can't burn the bootloader with USB UART

[miksumin]

I had to burn Optiboot from current version of MegaCore with copy_flash_pages function enabled. Still getting an error uploading the sketch: Connecting to board ... done Uploading sketch ... done An error occurred while uploading the sketch Flashing sketch ... Error flashing the sketch

[JAndrassy]

still "OTA upload response: Unauthorized"?

[miksumin]

No any response from sendHttpResponse

[miksumin]

Going restart after request received

[miksumin]

Connecting to board ... done Uploading sketch ... [restart] done An error occurred while uploading the sketch Flashing sketch ... Error flashing the sketch

[miksumin]

The same result using your example "OTEthernet.ino" with EthernetENC library

[JAndrassy]

I will test it with MegaCore version of the bootloader. did you use the latest vesion of MegaCore? Optiboot in older versions doesn't have copy_flash_pages function

[miksumin]

Yes, I used the latest one

[JAndrassy]

I tested it and everything works. But your uploads look like doubled. There shouldn't be "Flashing sketch" twice or "Flashing sketch" after failed upload.

[miksumin]

I am using ATmega2561 with ENC28j60 ethernet burned with optiboot_flash bootloader and your example "OTEthernet.ino" compiled in Arduino 1.8.7 using last version of MegaCore with EthernetENC library. What I am doing wrong?

[JAndrassy]

do you have upload verbose mode in IDE Preferences checked?

[miksumin]

Yes, of cause

[JAndrassy]

this could be related to enc28j60 and uIP stack. it can't finish sending the response to the upload tool and close the connection. try to add a beforeApply function. before setup define function

void beforeApplyUpdate() {
  for (int i = 0; i < 4; i++) {
    Ethernet.maintain();
    delay(UIP_PERIODIC_TIMER);
  }
}

in setup() add

ArduinoOTA.beforeApply(beforeApplyUpdate);
