Arduino Bootloader Burned Method

Introduction

When you have chosen the right board and port, and there is no connection between TX/RX and the circuit. If you still fail to deliver the code, the bootloader of your board may have lost, then you need to re-burn the bootloader to your board. Just take how to burn it to UNO as an example, there are two ways, if you already have one USBtinyUSP, the burning will be much easier, if you don’t have one, you can use UNO or Duemilanove as the programmer.


Method 1 Use USBTinyUSP as the Programmer

Preparations

-USBtinyISP Module (burning tool)

-Arduino Board (use Uno here)

-PC

-Arduino IDE

-USB cable

Wiring

Connect components as follows. Then connect the buring tool USBtinyISP to the computer by a USB cable. You can connect the Uno later because the UNO will take power from the USBtinyISP.

Arduino Uno R3 has two ICSP headers: one for the ATmega16U2 and one for the ATmega328. To reflash the bootloader on this board, you would use just the ICSP header for the ATmega328

USBtinyISP Module -------- Uno
MOSI --------------- MOSI
MISO --------------- MISO
RST --------------- RST
SCK --------------- SCK
VCC --------------- VCC
GND --------------- GND

Burn Bootloader

1)Open the Arduino IDE and choose your board type. What should be burnt here is UNO, so choose UNO.

2)Choose Programmer USBTinyISP here

3)Click Burn Bootloader

4)Wait for a while and if there appears Done Burning bootloader in IDE. It indicates that you have uploaded the bootloader successfully.

Method2 Use Uno or Duemilanove as the programmer

Note: After testing, this kind of method just used successfully in Arduino Duemilanove, arduino nano, arduino uno who use 328P.

Preparations

-2 Arduino Board ( One as the Prammer and one need to burn bootloader)

-PC

-Arduino IDE

-USB cable

Upload code to the Programmer

Open ArduinoISP.ino in File->Examples-> ArduinoISP and upload it to your programmer.

After Upload, it will basically act as an AVR programmer. This isn’t really recommended for production of boards, or boards with lots of memory, but, in a pinch, it works pretty well. Also as of this writing the code only works on ATmega328 boards.

Wiring

Wire your Arduino board to the target as shown in the diagram below. (Note for the Arduino Uno: you'll need to add a 10 uF capacitor between reset and ground.)
