I need someone with experience in troubleshooting and resolving this issue. Ideal skills for this project would include proficiency in Arduino, atmega2560, and troubleshooting. The project requires knowledge of hardware connections and software compatibility. The final deliverable should be a successfully bootloaded atmega2560 with no error messages.
