flash integration into Arduino GUI

[pgollor]

Hi everyone.,
first of all i would to says this project is a great one. :-)

I have a question. Is it possible to flash an Arduino directly from the Arduino GUI?
In the GUI i get under ports the esp link (this information comes from mDNS). But if i try to flash it i get the following error:

/usr/local/arduino-1.8.2/hardware/tools/avr/bin/arduinoOTA -address XXX.XXX.XXX.XXX -port {upload.network.port} -sketch /tmp/arduino_build_970563/Ofentermometer.ino.hex -upload {upload.network.endpoint_upload} -sync {upload.network.endpoint_sync} -reset {upload.network.endpoint_reset} -sync_exp {upload.network.sync_return} 
Resetting the board
Failed to reset the board, upload failed

XXX.XXX.XXX.XXX is the right address, but the other parameters are not be available.

• It is possible to use the ArduinoOTA script from above?
• Or could you integrate the avrflash tool into the GUI like this one under the tools menu?

My system:

• Linux
• esplink 3.0.14 alpha
• Arduino UNO
• Arduino 1.8.2

Thanks.

Thanks for your interest in esp-link! Yes, integration into the GUI is theoretically possible, but someone has to write the code for it... I never really used the GUI and am mostly using stm32 processors at this time, so I cannot spend the time to do the integration, sorry. Pull requests always welcome.

WRT the failure you're observing, I would highly recommend you use the avrflash script that comes with esp-link. It uses direct HTTP requests to esp-link to do the programming and will give you better error messages. Once that works, you can try arduinoOTA again (I didn't know that existed).

i am doing exactly this since quite a time using this great esp-link software - i am flashing Arduino devices installed elsewhere right from the Arduino IDE. All you need for this is a virtual com port (using a software like e.g. "netburner") pointing to the IP & port of the target...

Thanks for your posts. For me it is not problem to use the avrflash script or another solution. But I'm locking for a easy GUI solution for my project group in my university. An i have the same problem like @tve: the time ;)

@tve do you have any (easy to access) information for flashing an STM32 chip with esp-link? We are using STM32 boards too. Thanks.

not sure if i understood your problem - i also meant this to be an "easy GUI solution". I am using the Arduino IDE and click on "compile & upload" - that's it.
You only have to configure this once (for a target); with Linux, this is even more easy, and only a one-liner, e.g.:
socat pty,link=/dev/virtualcom0,raw tcp:192.168.254.254:8080&

You need to make sure it works using avrflash first, one that works, use the virtual com port.

Dunno about "easy" :-). I use stm32L0 and stm32F1 series that can be reprogrammed over serial and I use the update command in https://github.com/jeelabs/folie but you would likely want to extract the update code and make your own tool.

thanks for your info @tve

If someone else receives this error in the IDE (> 1.8.5):

I was trying to use the NodeMCU V3 Lolin instead of the ESP-01, and the IDE started reporting this error "Failed to reset the board, upload failed"

Then I realized that I was trying to upload to "Arduino UNO",
But the correct one is for "Arduino UNO WiFi".

I am using Arduino Pro Mini with UNO bootloader.
(Currently the Pro Mini bootloader does not work with Watchdog).

I was successful in setting up:
The assignment of "swap_uart" pins in the esp-link web interface,
(NodeMCU D6) GPIO12: connect to the RESET of the microcontroller
(NodeMCU D7) GPIO13: Connect to the TX of the microcontroller
(NodeMCU D8) GPIO15: Connect to the microcontroller RX (need pull-down to ensure proper startup)
