You may refer the pin diagram provided in step 1 or the datasheet of Atmega2560 for your circuits. Now you can upload your Arduino MEGA sketches & connect your own circuit keeping the crystal connection as it is & with above settings in tools. The LED connected to 2560 chip should blink. (or copy the code attached) & upload the code with following settings in tools: In void setup & void loop, change output pin 13, to 50. Now connect arduino board, open Arduino IDE & open 'Blink' sketch from Files-> Examples-> Basics. Now, REMOVE THE ATMEGA328 FROM UNO BOARD. Now as we have done bootloading, we proceed with uploading a blink sketch to our 2560 chip.ĭisconnect the Arduino from your computer.ĭisconnect the previous connections we have made, except the connections of the crystal to 2560. If everything is done correctly, the process will take some seconds and will finish with no errors. Connect the Arduino UNO board & open Arduino IDE, go to tools, and select as following:Īnd now from tools, click "Burn Bootloader". Save the changes and close the text editor. So the line could look like this (we can keep the original line commented as I did.) This is so, because in stand-alone ATMEGA2560 chips, if the BOOTRST fuse is not set, the chip will be correctly programmed, but the programs will never run. We have to replace the value of " 0xD8" with " 0xD9". Open it with a text editor (I used Notepad++) and locate to the ATMEGA2560 section. In my case, the path is "C:\Program Files (x86)\Arduino\hardware\arduino\avr". Once done with the connections, now find a file called "boards.txt" in your Arduino installation directory.
