Abstract

The invention provides an application program self updating and backup recovery method. The application program self updating and backup recovery method includes: dividing a flash memorizer of an embedded system into a Bootloader program area, a Boot parameter area, an application program parameter area, a main program area, a downloading program area and a backup program area; simultaneously supporting a local serial port to update an application program, download an update file into the downloading program area when the application program runs and restart so as to enter a boot program, wherein the boot program performs a verification test on the downloaded file, and copies the downloaded file to the main program area so as to achieve an application program self updating function. The application program self updating and backup recovery method solves the problem that several products which use the same series of platforms need to repeatedly achieve boot loading programs.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a method for self-updating and backup recovery of application programs. Background technique [0002] The bootloader is the first piece of code that the embedded system executes after it is powered on. After it completes the initialization of the CPU and related hardware, it loads the operating system image or the solidified embedded application into the memory and then jumps to the operating system. The space where the system is located, starts the operating system to run. Many embedded products today require the implementation of a bootloader. In this way, it is difficult to implement self-updating and backup recovery of the application program, and several products using the same series of platforms need to repeatedly implement the boot loader. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a meth...
