I'm having trouble burning bootloader to my new ATMEGA328-pu chips. I have two arduino UNO
I tried http://arduino.cc/en/Tutorial/ArduinoISP, this did not work. I even inserted a 124 ohm resistor from 5v to reset and a 10uf cap from reset to ground. Found this on a forum somewhere.
my steps. -> select arduino isp sketch in the examples,,, then go to tools -> Programmer -> arduino as ISP
then -> tools burn bootloader.
AVR dude sync error
C:\Users***\Documents\Arduino\optiLoader\optiloader.ino and optiloader.h
changed name of the Include Wprogram.h to arduino.h as im using the new arduino IDE 1.0
then I go file->sketchbook-> optiloader.
upload it....
i get Binary sketch size: 13018 bytes (of a 30720 byte maximum)
avrdude: stk500_getsync(): not in sync: resp=0x00
Furthermore, when I try upload to arduino the serial rx and tx do flash then all of sudden stop and then with a little bit of a wait then I get the error above.
Hi,
Strongly recommend optiLoader, have used it program ATMega8's.
You run the sketch on your main Arduino, the sketch contains three copies of the bootloader within itself and uses these copies to load your target chip. It has a copy each for ATMega 8, 168 and 328.
It gives useful feedback during the processes so you have a good chance of troubleshooting should you need to.
One tip - double check your wiring before powering up the two boards, a mistake could lock you out of the target chip, other than that it is pretty simple.
You can use the same breadboard wiring as used in the ArduinoISP tutorial, use the version withe crystal, the bootloaders in optiLoader are design for boards with a crystal.
Hi
I have been also trying to burn a bootloader onto an Atmaga 168 20PU on a breadboard from an Arduino Uno. I have set up the board as shown in DuaneB's post and also played with putting in a 120 ohm resistor and a 10 microfarad capacitor between 5v and reset. I also added this code to the end of the boards.txt file as suggested on the old forum
##############################################################
atmega168bb.name=ATmega168 on a breadboard (8 MHz internal clock)
I load in the ARduino ISP from the examples menu then select Arduino Uno for the board and upload it . All Ok so far. I then hook up the reset override resistor between the reset pin and the 5v rail and set "Arduino as ISP" for the programmer and "ATmega168 on a breadboard (8 MHz internal clock)" for the board then do burn bootloader.
I get this message "avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check."
I have double checked the connections and am sure they are right. I saw somewhere something that says you can't do this burn to a breadboard process from an Arduino Uno. Is that correct or should the changes described above fix this?
I saw the references to Optiloader on Github and tried to do something with that but I'm not sure where to put the header file and the pde file. I tried compiling the pde file in sketch but this give me errors.
Is there a problem with the code I added to the boards.txt file? or can anyone sugegst how this process should work for an Arduino Uno and an atmega168 20PU on the breadboard. I haven't put my 16Mhz crystal and 18-22pf capacitors on the breadboard as the boards file addition post suggested they should not be used
I've been struggling all day so any help would be much appreciated.

I've given optiLoader a try with apparent success as follows:
OptiLoader Bootstrap programmer.
2011 by Bill Westfield (WestfW)
Target power on! ...
Starting Program Mode [OK]
Reading signature:950F
Searching for image...
Found "optiboot_atmega328.hex" for atmega328P
Start address at 7E00
Total bytes read: 502
Setting fuses for programming
Lock: 3F FFE000 Low: FF FFA000 High: DE FFA800 Ext: 5 FFA400
Only problem is that if I then take the bootloaded target and install it into my Arduino Duemilanove board I get the following error when attempting to then load a normal sketch.
avrdude: stk500_recv(): programmer is not responding
I'm using Arduino IDE 1.0 under MacOSX 10.6.8.
This seems to suggest the optiLoader bootstrap is incompatible with IDE 1.0.
