Error while boot loading Atmega 2560 using Arduino Mega 2560

Question

I have developed custom board using Atmega 2560. I am doing boot loading process using the process of migrate from an Arduino board to a standalone microcontroller.

Custom Atmega 2560 Board

I have followed this steps...

1) Upload the ArduinoISP sketch onto your Arduino board.

2) Wire up the Arduino board and microcontroller as connections mentioned on Arduino Site.

3) Select "Arduino/Genuino Mega/ Mega 2560" from the Tools> Board menu.

4) Select "Arduino as ISP" from Tools> Programmer

5) Run Tools> Burn Bootloader

While doing this process I am getting this Error...

avrdude: Yikes! Invalid device signature. Double check connections and try again, or use -F to override this check. Error while burning bootloader.

I have done connection like this...

MISO - D50
MOSI - D51
SCK - D52
Reset - D53/Reset
+5V - Vcc
GND - GND

What wrong I am doing? Or any step I have missed?

• Sagnik Pradhan: Is that a clone of mega just without the FTDI IC ?
• karanrp: @SagnikPradhan Yes it is a clone without FTDI IC

Answer 1

You wired the whole thing backwards. The proper wiring is

Your board - Arduino
 MISO - D50
 MOSI - D51
 SCK - D52
 Reset - D53
 Vcc - 5V
 GND - GND

This is kind of obvious from the picture: you would normally use the ISP connector of the target board.

Answer 2

Same connections worked for me. Just one connection have to change.

Reset - D10
