When i try to upload the blink example i get an error which says.
avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check.
I know that the issue is with avrdude but 0011 has no issue with the same example.
What could be causing this?
Which chip are you using?
You can modify the software to pass a -F to avrdude to override
There was a post showing how to do this on the forums
On Linux you could run it by hand
avrdude -F -v -v -v -v -pm168 -cstk500v1 -P/dev/ttyUSB0 -b19200 -D -Uflash:w:program.hex
This assumes you have an ATmega168 and your board is attached to /dev/ttyUSB0
avrdude uses the same options on other operating systems but you need to pass the correct port ( -P option ) and so on
Probably you have a fried ATMEGA168 chip.
I hope it isn't fried, it's barely been used. In any case it works fine in the Arduino 0011 IDE.
I'll have a look at passing the option with avrdude. I have i may have seen something too. Maybe at ladyada.
Are you sure you have the right board selected under the Tools->Board drop down in the Arduino IDE?
I don't think it remembers your selection across upgrades
Yep, i'm pretty sure. It was the first thing i checked. I can't get to my main pc right now so i can't re-check for a while.
Try to run avrdude by hand as mentioned earlier with the -F and see if it works
That'll tell you what's going on
Hi all again. Thanks for your help.
Ok, i ran the command with the Blink.hex file. Absolutely no problems.
I then went back to the IDE and de-set the Board selection. When i did the program hung for a bit and then the following was spit out.

Reselected the Diecimilla (the same warnings flew out again) and tried to upload the hexfile. No dice.

There should be a custom version of avrdude that comes with the Arduino software. The standard one can't read the device signature from the bootloader on the Arduino.
Ah. Just copied over the file "avrdude" to remove the symlink. All is fine. Someone remind me in 2 days to edit the Gentoo-Linux install guide.
