tried to bootload an atmega8 on a breadboard but always get this error.
Error while bootloading
avrdude: stk500_getsync(): not in sync: resp=0x15
Help please
thnx
There's a great Instructable about putting Bootloader on many different ATMEL's here:
The kid who wrote this is way cool... 8)
i followed this one,
negative results though
Have you disabled autoreset?
After much searching I found that disabling reset involved putting a 120 ohm resistor between 5v and reset on the arduino doing the burning. It worked for me. I think people need to be a bit more specific when they say simply "disable autoreset." I think the tutorial needs to be updated because it is pretty useless without that step. I never was able to upload sketches though. Once the chip had the bootloader I could plug it into an arduino and upload the sketch that way, then remove the chip and put it back in the breadboard- not the most elegant solution but it worked.
I used this one:

It's more thorough.
i dun have breakout boards
can i ask something, i did put a 120 ohm resistor from reset to 5v pin
but didn't remove the 10kohm resistor connected from the reset pin to the source.
ive been trying to bootload this atmega8 for 2 days, i didn't find any solution to my problem.
please help me i need this on monday. Thanks
Which Arduino model are you using?
Im using arduino duemilanove as the ISP
and im bootloading atmega8 on a breadboard.
I followed this link http://arduino.cc/en/Tutorial/ArduinoISP
additionally I added the 120 ohm resistor b/w the reset and 5v pins to disable autoreset.
but still dun have positive results.
using this atmega8L-8PI
I need this bootloaded tomorrow
anyone willing to help please..
I haven't tried the resistor to prevent reset so I don't know how well it works.
If you have a serial cable with a MAX232 or the like (connected to TX & Rx) you can use that and you won't get a reset. That worked very well for me.
I do know that if the ArduinoISP resets when you try loading the ATmega8 sketch through it - your hosed.
Other options are here

if you haven't seen it. Good luck.
Thanks for those who helped I already got it.
I used the core files from avr developers.
Thanks a lot, the links helped a lot.
hey,
So did you finally get the bootloader working on Atmega8L ?
Even I've some of these lying around, could you share your settings please.
