Arduino Bootloader Burning



If you are working with arduino, you must know about the BOOT LOADER of arduino. When you buy ATMEGA chips those are coming with boot loader and without boot loader. If it is with boot loader no issue. You can programme the IC directly. But if it is without the boot loader , you have to burn the boot loader. Remember that most of ICs with boot loader are bit expensive than without boot loader.

In this tutorial, I will explain you the way of burning boot loader for well known ATMEGA328 IC using
  1.     Arduino Uno
  2.     Arduino Mega
  3.    On bread board

The thing you should understand that, if you want to update boot loader, you must have atleast one Arduino board and ATMEGA chip with boot loader.

  1.    With two Arduino Uno boards

In this method you must have two Arduino Boards

  • Arduino Boards =  2 Nos
  • Atmega 328 with boot loader = 1
  • Jumper Wires


STEP 01
Install the Atmega 328 with boot loader IC to the Arduino Uno board and Connect the Arduino Uno to PC

 

STEP 02
Run Arduino Software and Files > Examples > ArduinoIsp > ArduinoIsp

STEP 03
Select from Tools > Board > Arduino Genuino/Uno

STEP 04
Select from Tools > Programmer > ARISPMkll


STEP 05
Select from Tools > Port > Relevant port

STEP 06
Now upload the programme from Sketch > Upload
Once the upload is completed you have to connect the ARduino Uno board (Programmer) with 2nd arduino board (Target board) with the chip without Boot loader.

Wiring connectors as follows
Programmer
Target Board
+5v pin
+5v pin
GND Pin
GND Pin
Pin 13
Pin 13
Pin 12
Pin 12
Pin 11
Pin 11
Pin 10
Reset


STEP 07
Once the wiring is over ,
Go to Tools > Programmer > Arduino as ISP

 STEP 08
Now to burn the bootloader go to Tools > Burn Bootloader



It will take a time to burn the boot loader, then once the burning is completed you can start programming. But do not forget to change the settings as Tools > Programmer > ARISPMkll.

02. Using Ardduino MEGA




In this, the PROGRAMMER is Arduino Mega and the Target is Arduino Uno.

You need the followings
  • Arduino Mega board (as the Programmer)
  • Arduino Uno Board
  • 10uf Capacitor
  • Jumper wires



STEP 01
Connect Arduino MEGA to PC

STEP 02
GO TO TOOLS > BOARD > ARDUINO/GENUINO MEGA OR MEGA 2560

STEP 03
Select the PORT

STEP 04
GO TO TOOLS > PROGRAMMER > AVRISP mkll

STEP 05
GO TO FILES > EXAMPLES >Arduino ISP > ArduinoISP

STEP 06
SKETCH > UPLOAD

Once the upload is completed, you have to connect the Target board with without bootloader IC to the Programmer board which is Arduino Mega.

Wiring Details as Follows
Programmer (MEGA)
Target (UNO)
+5 V
+5 V
Ground
Ground
PIN 50
PIN 11
PIN 51
PIN 12
PIN 52
PIN 13
PIN 10
RESET
Connect Arduino Mega reset pin and ground pin using a 10uf capacitor.


STEP 06
Important : Arduino MEGA should be connected to PC
GO TO TOOLS > BOARD > Arduino /Genuino Uno

STEP 07
GOTO TOOLS > PROGRAMMER > Arduino  as ISP

STEP 08
TOOLS > BURN BOOTLOADER

Once the burning is completed, you can use the arduino uno (atmega 328) for programming. Only change is when we burning boor loader we connect Arduino Mega but we select the Arduino uno from Board.


Do not forget to change as TOOLS > PROGRAMMER > AVRISP mkll after burning is completed for programming.


03. Single Board Method

What if you have only one board either Arduino Uno or Arduino Mega. So, this is the way to burn boot loader in such a situation.
You need the followings,

  • ATMEGA 328IC
  • 22pf Ceramic Capacitors x 2
  • 16 MHz crystal x 1
  • Breadboard


Make the TARGET board as the described in my Arduino on vero board tutorial. The you can burn the IC using either 1st method or 2nd method having followed the above steps.
