Hi,
I have a custom board with mega2560 chip and W5500 ethernet controller.
There is no USB port and I use any bootloader.
I currently program it through ICSP.
I tried ArduinoOTA library but whenever I try to upload the code, the IDE asks for password, then gives this error Resetting the board Failed to reset the board, upload failed
Has anyone here successfully programmed any mega board over the air?
of course it works. it is not a joke.
but you must have the Optiboot bootloader from MegaCore, which supports bootloading from internal flash memory for the ArduinoOTA library.
I did try the bootloader mentioned in the link as modified optiboot. But I am still getting the same error.
I will try again and state the exact steps that i am following
