Hi I’m trying to follow this guide: http://hackaday.com/2010/10/25/avr-prog … -hardware/ to get started with AVR and I’m having some problems…
I’m using an AVR Dragon on OSX… I checked the connections and pins 10 times… I’m getting the following error:
avrdude: Device signature = 0×000000
avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override this check.
NOTE: I’m using a 328 instead of a 168… but I checked the datasheet and the pinout is the same… Any advise?
Here is a screenshot of my terminal output and my wiring

(also note I brought up the command I used at the bottom of the screenshot)

Also, to further test the wiring I tried disconnecting the VCC wire from the ribbon cable and I got this error… which seems to say it’s hooked up correctly (in my mind)?

Please note I’m a TOTAL beginner at this whole AVR thing (hence why i’m trying to make an LED blink) … My best guess so far is that it has something to do with the “fuse bits”? However, I have no idea how to check this or fix it…
I purchased this chip new from sparkfun… I have 2 (I tried both with the same outcome)… I do remember an option to have them install the aurduino bootloader (which i said no to) is there a chance they sent me one with the bootloader? would that cause this problem?
is there any way to do like a factory reset on the chip?
any help is MUCH appreciated. I usually NEVER ask questions as most things can be figured out with google, but since I’m TOTALLY new to this I don’t even know where to start.
thanks in advance
