USB bootloader of ATSAMR21 MCU


My MCU is a ATSAMR21E16 of Microchip company.

My board was already manufactured and there is only one MCU as CPU.

I am going to look over the boot load method using USB port which is directly connected to the MCU.

Of course, I have a main firmware and if you can deliver the code of USB bootloader, then I will combine them.
