I have the Atmel Ice available to flash the ATSAMD21G18-MU microcontroller which I am using. I believe I need a hex file that will be executed during the flashing/bootloading process.
Would I be able to use this github file here as a hex file to flash?
My main goal is to flash the IC to upload code using the native MicroUSB port of my PCB. I am fairly new to this so any advice and helpful information is greatly appreciated.
