6. Firmware encrypt
In order to make sure the firmware could not be modified after programming in the module, firmware must be
encrypted with the bootloader drivers and the chip ID MXCHIP offered.
Bootloader driver is used to drive the device in the module and integrated with one AES encryption way. The
application part of the firmware must be combined with the bootloader driver to generate one MVA/bin file after
adding the chip ID details which can be used to identify MXCHIP module. Check the official website for more
information.
