hi,
ive made a board based on the arduino micro schematic, and flashed using the Caterina-Micro.hex bootloader. I have made two boards off the same schematic. Im using Atmel-Studio.
The first board once i set the fuses worked fine, fully recognised USB Serial COM port, and also accepts uploads using the Arduino IDE.
The second board also shows up as a USB Serial port in device manager, and if i do a hold reset down and release once the Arduino IDE is looking for the COM port it finds the COM port but cant find the programmer.
any tips??
should i try a different boot loader??
