I had programed the Atmega64A once, so i don't think there was any problem with my connections, i used the usbtiny programmer, when i executed the command, show the error:
Code: Select all
C:\>Avrdude -c usbtiny -p t85
Avrdude: Device signature = 0xffffff
Avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override this check.
i had tried 20 pieces, always show this error.
can anybody help me ?
I will be crashed....
help...help...
