i have been searching the net and trying, i still can’t get the bootloader to go on the blank chip….I am usint the Diavolino as my ISP…i keep getting this for the last 2 chips i tried
avrdude: Expected signature for ATMEGA328P is 1E 95 0F
Double check chip, or use -F to override this check.hope somebody can help…i am pulling my hair out
Can you say what signature you *are* getting?
There is supposed to be a line above that one, saying what it actually read– the “expected signature” line always follows that if the value is wrong. It should be something like “avrdude: Device signature = 0x1e9514 .
You may need to just scroll up a line to see it.If you’re doing this from within the Arduino IDE, you may need to turn on verbose mode in the preferences.You *do not* want to override the check. This is a *symptom* of something else wrong, not the cause of the problem.
Do you have the verbose option turned on?
And, to be clear, you are *not* reporting nearly enough information here to figure out what the problem is. I can give you a list of things to check (like, for example, that your target chip actually is an an ATmega328P), but until you can see the actual error, it’s pretty hard to guess what might be wrong.
Exactly what chip are you using? Are you certain that it’s a ‘328P, not just a ‘328?
The verbose option, as I said, is in the Arduino preferences.Yes, that would be the problem right there. That’s actually a different chip, with a different signature, from the one supported by Arduino.
You can work around this by changing the expected signature in your avrdude.conf file, following the instructions from this thread: http://www2.evilmadscientist.com/forum/viewtopic.php?showtopic=4997
