Hello everyone!
I have just solved the programming issue thanks to this thread and want to share the experience.
Google does not have exact steps for the solution so I have decided to continue this conversation
In all "out of the box" arduino IDE I had the following error messages for Mega2560 board
Can't find programmer id "wiring"
But thanks to clever people above, I have found what to do.
-
Open boards.txt and find
mega2560.upload.protocol=wiring -
Replace this string with
mega2560.upload.protocol=stk500v2 -
Save the file and restart IDE
-
In main menu Tools->Programmer please change AVR ISP MKII to AVR ISP
-
Program your sketches fellas!!!
