I have some Atmega328-Pu micro-controllers without boot-loader program. Now I need to burn boot-loader to them all. I have two arduino uno boards having Atmega328 P-Pu micro-controllers on board. I used this circuit from this page Installing an arduino boot-loader It does not work. The boot-loader is not uploaded. Can you please help me out? If you need any more informations please ask. I have been struggling with this kind of boot-loading techniques for more than a week. I am using arduino IDE 1.0.1 and the board is Arduino uno R3
Hi friends thanks for your support. It worked well as it is. No external capacitor I used. I made the connection as shown in the above picture taken from LINK1. I modified the file "boards.txt" and "avrdude.conf" as given in step 4 of LINK2 I first uploaded the ArduinoISP sketch to the board on the left. And then I opened an "EMPTY ARDUINO SKETCH". From that empty sketch I made the following changes Tools->Board = "Arduino328" Port = COM4 in my pc Programmer = Arduino as ISP Last step "Burn Bootloader" Ta Da.... It worked. When I posted this question I burnt the boot-loader having the arduino ISP sketch opened. Only thing I changed now is I opened an empty sketch and hit burn from that sketch. Anyway.. thank you all. I dont think I wasted your time. If so, I apologise.
