The invention relates to the field of electric
digital data processing, and discloses a remote upgrading method based on an STM32F746 processor, which comprises the following steps of: dividing a program memory into four regions, namely a boot region, a running region, a
backup region and a
system variable region, the boot region is used for storing a bootloader program and finishing the moving and starting guidance of an application program; the running area is used for storing a truly running user application program, completing transmission and
processing of a remote upgrading file and storing the remote upgrading file in the
backup area; the
backup area is used for storing a new version of user application program which is remotely upgraded and transmitted; the
system variable area isused for storing
system variables. According to the remote upgrading method, the remote upgrading function is realized; according to the technical scheme, remote transmission of the application program can be completed under the condition that the overall function of the system is not affected, and even if transmission interruption is caused by human or non-human factors in the transmission process, it can still be guaranteed that the equipment normally operates after being powered on next time, and the application program needs to be upgraded to restart
remote data transmission.
