The invention discloses an HTTP (
Hyper Text Transport Protocol) transmission method remote OTA (
Over the Air) upgrading application
system based on a domestic micro controller, which relates to the technical field of embedded systems and comprises a processor and HTTP
server connection establishment module, a Flash storage partition planning and configuration module, a
firmware file
processing module, a program
processing module and a
database, the FM33LG0xxA series processor performs data interaction with the 4G module, logs in to connect with the
server with an HTTP
server, divides a Flash model into a Bootloader program area, a local user program area App1, a remote OTA user program area App2 and a flag bit
storage area, then generates a flag frame and a data frame, finally verifies the integrity of a remote OTA program, and determines the integrity of the remote OTA program according to a
firmware version, a mandatory bit and a hardware ID. Whether the remote OTA needs to be upgraded or not is judged, the accurate matching performance of the domestic micro controller and the 4G module and the file
information analysis efficiency are guaranteed, and the accuracy of remote OTA upgrading judgment is also guaranteed.
