Hi everyone,
I'm new at using Arduino and in particular at using the microcontroller Atmega328P-PU.
I've benn trying for days to burn the bootloader on my atmega with an arduino uno, but it doesn't want to work. I'm very disappointed because I bought it with the bootloader and it worked fine but at 1MHz and I wanted one faster for different purposes.
I've tried many tutorials. I'm sure about my wirings, because I used EXACTLY the same with an ATmega known to work and everything worked fine with it.
Here what I've done : I wanted to burn the bootloader with my arduino uno. I wired my atmega up and I configured the file boards.txt to burn a bootloader at 16mHz. It failed, and I learned after that I needed an oscillator to do such a thing. So I bought one and and two capacitors at 22pF as specified in many tutorials. I tried again and here's what I've got when I try :

Double check connections and try again, or use -F to override

avrdude done. Thank you.
I don't really understand why the oscillator is "off" along this log as I wired it on my breadboard.
If someone has an idea... Otherwise I will throw away this atmega and stay with thoses which works ^^
Thx
