    Hello. 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. Regards.
