Hi everyone! I recently designed a circuit around the ATMEGA328P-AU (TQFP package) and was having trouble communicating with it. I salvaged an old Arduino UNO and loaded it with the ArduinoISP sketch. Hooked up the 328P through a breadboard and went to burn the bootloader and got the error message:…

I believe I have figured out the issue. Bear with me. With the 328P on the breadboard, it required an 8 MHz crystal to function. The issue was that I was using 10 nF caps instead of 22 pF caps like the tutorial recommended. So crystal with no caps worked fine Going back to my main circuit board, l…

There is a jumper to 5V missing in the image, vs. the Fritzing you posted.
