Embodiment 1

[0023] As shown in Figures 1 and 2, in the prior art, the method for updating the embedded system loader and application program requires two operations, one for burning (Figure 1) and one for downloading (Figure 2).

[0024] As shown in Figures 3 and 4, the integrated update method of the embedded system loader and application program includes the following steps:

[0025] (1) Input the loading program, loading information and application program into the computer, compile the combination of the loading program and application program through the compiler, and generate data that can be burned at one time, and the data is output from the computer to the burner, and burned The device is burned into the unique set of memory FLASH ROM of the embedded processor through the burning cable; the loading information is used to save the information of the application program that needs to be loaded;

[0026] At the same time, the application program is decomposed from the compiled loadi...

Abstract

An integral-updating method of embedded system loading program and application program includes downloading function program and receiving program data transmitted from communication interface to finalize back-up application program when embedded operation system and application program are started up, activating back-up application program and setting current application program state to be back-up state when download is finished, resetting system and loading new application program for carrying out operation.

Description

technical field [0001] The invention relates to an update technology of an embedded system software program, in particular to an integrated update method for an embedded system loading program and an application program. Background technique [0002] Embedded systems are application-centric, special-purpose computer systems with tailorable hardware and software. It is generally composed of embedded processors, peripheral hardware devices, embedded operating systems and user applications, and is used to control, monitor and manage other devices. The startup sequence of the embedded system is generally, when the system is powered on, the CPU runs from a fixed address, usually the 0x00000000 location of the FLASH ROM; The system boot environment starts the embedded operating system and application programs. The download mode is used to complete the user's work of updating the operating system or application program, and this part of the work program is usually stored in an is...
