Hi, it should be filled as 2 independent issues. 1) move to another issue - need to check it how it is possible 2) MegaCore uses optiboot - so it is more like an issue for MegaCore/Arduino IDE
"flash2560.py" or "megaflash" are designed for original mega bootloader
esp-link still has no support for 2560 with optiboot - it is on my really long todo list, maybe I need to give it a try
hello, thanks for your response.
i read anywhere if i use optiloader the OTA works with esp link. maybe it was a uno i dont know.
so if i want a working 2560 with esp-link i should use original arduino (Arduino as ISP) Bootloader ? OTA Upload is working only with fllash2560 and megaflash ? Im sure i tried with clean arduino mega bootloader and tried network upload but i get a "ip not reach" or "cant access" errors. Tried clean ide installation too.
maybe we can tweak esp-link to work with MegaCore optiboot as expected need to find my mega board and reflash bootloader from MegaCore
no u dont need to if u say original bootloader works normally i could use it. i only heard from optiboot because i searched for my problems in google .. i didnt know before
sometimes cheap chinese clones of mega have different bootloader - don't know what it is exactly and you need to reflash original
i reflashed original (Mode Arduino as ISP)
Hello Dear esp-link community
first im running Windows 10,
i bought this board and i would like to use esp-link so I can OTA update the ATmega2560. Wemos Mega: https://www.banggood.com/Geekcreit-Mega-WiFi-R3-Module-ATmega2560ESP8266-32Mb-Memory-USB-TTL-CH340G-p-1205437.html?rmmds=search&cur_warehouse=CN schematics in the "documents"-tab
im sure the dip switches are set correctly and espt-RxTx goes to uart3
esp-link version: 3.2.47 alpha is working fine on the esp. WebInterface and RX/TX console work fine.
i think my problems are somehow related:
1) i connected the gpio12 to the reset of the atmega when i hit the Console>reset uC Button in the esplink web-interface i get a message "Error Resetting uc". But i know for sure that the atmega resets fine, why doesnt the web interface show this correct?
1.1) if i remove the resetpin from esp to arduino the reset uC Button replies: reset ok. but i see no reset - as there is no connection between esp and atmega.
2) uploading via IDE no working
either i get the the following error when i use Board Arduino Mega/Mega 2560: "Resetting the board Failed to reset the board, upload failed An error occurred while uploading the sketch"
or i get this error when I use MegaCore Atmega 2560: "avrdude: ser_open(): can't open device "192.168.0.24": The system cannot find the file specified."
i tried both bootloader with both board options - a fresh arduino bootloader and the optiboot bootloader - but no change. cant get the phyton "flash2560.py" or "megaflash"-script to work. should i give this another try ?
does esp-link OTA even work with atmega 2560?
i wish u a great new year and thank you
