I have a new atmega328p IC that I wanted to program. To do so I placed it into the socket of an arduino uno. I accidentally placed it the wrong way around (180° rotated), and powered it via USB and tried to upload the blink sketch, which obviously did not succeed. After I noticed it I turned it around and placed it into the socket the right way. I tried again uploading the blink sketch again without success.
- Have I fried the atmega328p by placing it in the socket the wrong way?
- Is there something else you need to do to new atmeag328p before you can program them the usual way?
Update: It seems that just rotating the IC did not damage it in the state where there was no bootloader programmed. And and the bootloader needed to be programmed first before the IC could be used.
