i bought new atmega 328p for my ardurino with bootloder from ebay and change it and it now showing that your programer is not responding ,i tried with my previous chip and it work fine..how could i resolve it
- Did u mount the chip the right way round?
- Maybe it does not have a bootloader.
You could breadboard the chip into a "standalone" Arduino and test it.
Otherwise try re-burning the bootloader.
