I'm currently in the middle of a project in which I've made a pcb equipped with a Atmega328-AU. Unfortunattely I'm not able to burn a bootloader on my chip, I'm using an arduino UNO to do so. The error message I get is: "avrdude: Yikes! Invalid device signature. Double check connections and try again, or use -F to override this check."
Though, I checked my connections multiple times. I guess it has to do with the signature bytes of the 328-au?
Any suggestions on how to solve this are welcome!
