The STM32F7xx, which is used for the main MCU on the OpenCR board, supports

DFU(Device Firmware Upgrade). This enables the built-in bootloader of the MCU by itself to

boot the DFU protocol by using USB, primarily for the bootloader initialization, the recovery

mode, and the bootloader update. The biggest advantage to let the users be able to use

bootloader with USB but no other JTAG equipment. Write the firmware by using the DFU

mode which is embedded in MCU without writing / debugging equipment, such as STLink.
