Arduino how to burn bootloader into other chips

we may encounter such situation bootloader falls off when using arduino, thing can freak out when got no bootloader tools on hand. shall do? here we'll introduce way on how burn bootloader via arduino, rather practical in cases when without bootloader burning tools , no arduinos.

1. burning preparation

* arduino duemilanove

* dupont line

* in-line resistance



2. burning process

(1) burn arduino isp arduino duemilanove.
* open arduino ide 1.0.5, select arduinoisp under secondary menu "examples" of file.



* compile arduinoisp code , download arduino duemilanove. note must refer picture below select board.




note: must follow picture select board; serial port number, select according actual port number of ide.

(2) burn bootloader uno's atmega328p via arduino duemilanove.
* connect isp burning port of arduino duemilanove uno's burning port via dupont line.



* short 100 ohm resistor between reset pin , 5v on uno.



* configure arduino ide achieve bootloader burning functions.





follow mentioned guides click on burn bootloader, wait short period of time, below prompt appear indicate burning done successfully.



note: if still can't done though covered steps, please check resistance between reset pin , 5v pin. sure resistance must around 110 ohm.

can't correct. target's reset pin on target's icsp connector must wire digital output pin on 'programming uno' board. wiring reset pin reset pin not going work.
