I created a PCB for a project and the main chip is the atmega32u4. I have tried burning the Leonardo Bootloader to it using an Arduino Uno with Arduino as isp for the programmer. The Uno has the ArduinoISP sketch uploaded to it. The error is "Yikes Invalid address of 0X00000".
I realize I have missed some components and connections on the Atmega32u4, but I have now fixed them.

Any help would be greatly appreciated.
