I have two sunfounder mega2560s. I am using one as an ISP programmer and the other is my target. The programmer has the original bootloader on it. I have placed the ArduinoISP sketch on my programmer and connected LEDs and stuff as here: https://www.arduino.cc/en/pmwiki.php?n=Tutorial/ArduinoISP
I have connected all six pins on my programmer to all six pins on the target. I'm using the ICSP towards the middle of the board on both boards as opposed to the one near the USB cable.
I am trying to place megacore on the target. I have followed the directions here: https://github.com/MCUdude/MegaCore#how-to-install.
I am running Arduino IDE on Windows 10. I am selecting Tools->Board->megacore->Mega2560 and then Tools->Programmer->Arduino as ISP.
I believe all of this setup is correct, so I Click Burn Bootloader. I get the following results:
Arduino: 1.8.15 (Windows Store 1.8.49.0) (Windows 10), Board: "ATmega2560, Yes (UART0), EEPROM retained, Arduino MEGA pinout, BOD 2.7V, LTO disabled, External 16 MHz"
avrdude: Version 6.3-20201216

Double check connections and try again, or use -F to override
this check.
avrdude done. Thank you.
I have double checked all of my connections and am powering the target 2560 from a power block on a USB cable.
All research on the web turned up only issues with connections or separate power. Also, I don't know how to use the avrdude from the command prompt to add the -F as suggested.
Having tried everything, I'm looking for help here. Thanks.

The answer was that you must connect the reset pin of the target ICSP to pin 10 of the programmer Mega 2560. This was not very clear in the tutorial here: https://www.arduino.cc/en/pmwiki.php?n=Tutorial/ArduinoISP.
This fixed the problem for me, so it was a connection issue.
I have connected all six pins on my programmer to all six pins on the target. I'm using the ICSP towards the middle of the board on both boards as opposed to the one near the USB cable.-- That sounds very wrong. I suggest finding a reliable tutorial to follow.
