I have built a custom ATmega2560 with some extra features and program it via Arduino ISP. When I burn the bootloader on it I manage to upload a new program via TX, RX but when I try to upload a new one I get an error and can't program it until I burn the bootloader again. The bootloader that I use is from the Arduino IDE. Can anyone help?
