Thank you, Mr.Coding Badly.
Sometime I can burn the bootloader,other time I can not with same bread board. I think it is problem of the bread board. By the way, when I can not burn, the following message is showed. Does anyone have advice?
avrdude: Expected signature for ATMEGA328P is 1E 95 0F.
Double check chip, or use -F to override the check.?
This means that avrdude cannot recognize the mcu or can't correctly communicate with it.
Doublecheck your connections.
but avrdude reads a different signature than the expected or it doesn't read any signature?
