I am using Microsoft Visual Studio Community 2013 C# to develop firmware for G400-D Dev Board. Now I am using USB-Debug port on Dev Board for development.
I know there is a bootloader inside microcontroller. How to use USB<->Serial COM1 or RS232 COMM2 port to upload hex file into the Atmel microcontroller? With Microsoft Visual Studio Community 2013, how to generate hex file? I looked at GHI Bootloader document, cannot understand it. Is there a step by step procedure of doing it?
