Do I need to connect both boards with USB as well as independent power?
Which serial port# do I use in Arduino IDE if both boards are connected via USB leading up to the next step?
Do I need to open Nick Gammon programmer sketch into Arduino IDE and select "upload using programmer" or "Burn Bootloader" with that sketch open using the programmer and targertas in step 4). Or do I upload to Arduino Diecimal (Both approaches timeout or say out of sync)"Upload Nick Gammon Programmer" to Arduino programmer or "Upload using Programmer with Nick Gammone Programmer" to Target Atmega2560?
After that the last step is to Burn Bootloader?
Arduino Diecimil capable of performing the role as a programmer?

Thank you.An error occurred while uploading the sketchThis report would have more information with"Show verbose output during compilation"option enabled in File -> Preferences.
I used the my custom programmer to upload this sketch that keeps failing via USB using the ISP communication
