Hi all, I bought a ATMEGA328p from ebay, already programmed with the bootloader. It also has the blink sketch running on it. I was hoping to use my uno to act as a programmer so i could download a sketch that I want to run in a standalone project.
When I put the processor in the uno I can see the blink sketch starts up but I cant download to it. I get this error avrdude: stk500_getsync(): not in sync: resp=0x00. When the IDE is trying to upload I see the RX led flash a few times then nothing and the blink sketch continues to run.
I have just put the original 328p back in the same board and that will upload fine.
Is there something vital I'm missing or is it likely to be a dodgy processor?
