  • ATMEGA2560 Standalone Using Arduino UNO

    Seems some communication issue.. as your bootloader got programmed and you were able to program 2560 with blink.Check your crystal & capacitors connection once again. Make sure the crystal and the capacitor are connected neatly and are tight. If you see in the very first image of this instructable (the one before the start of this instructable), you will see that I have put cap pin and crystal pin in only one hole of the red breedboard.Try to keep it as close as possible and make sure the connection between the 2560 and crystal circuit is good and is nor floating or loosely connected.Hope this solves your problem

    Hello,First of all sorry for late reply..Assuming you have kept the crystal connections as it is while uploading your program & settings as I told.I understand your problem, it seems that you did not edit or incorrectly edited "boards.txt" file.. because if you incorrectly edit the file, your program will get uploded but never run.Follow the "Step 5: Bootloading 2560. Part II"this may solve your problem :)

    I got your problem..This device signature issue is not new..Can you tell me the exact number of your 2560 IClike for me it is "ATMEGA2560 16U-TW"The number after ATMEGA2560 if different, causes this issue..I'm soo sorry for late reply

    Thank you :)
