Partial upgrading method of embedded software

Abstract

The invention provides a partial upgrading method of embedded software. The partial upgrading method of the embedded software comprises the following steps: S1, generating an embedded operating systemfile in an ELF format by using a compiler; S2, downloading the embedded operating system file in S1 to a single-chip microcomputer system, and running the embedded operating system file; S3, generating an upgrading program file X in an ELF format by using a compiler; S4, transmitting the upgrading program file X to the single-chip microcomputer system through a communication link; S5, after the single-chip microcomputer system determines that transmission of the upgrading program file X is completed, the embedded operating system verifies the effectiveness and integrity of the file; S6, performing an upgrading operation, wherein an embedded operating system in the single-chip microcomputer system analyzes the received file X data during upgrading. According to the partial upgrading methodfor the embedded software, the software upgrading speed is increased, the upgrading stability is higher, and the steps are simple and easy to implement.

Description

technical field

[0001] The invention relates to the field of embedded software, in particular to a partial upgrade method of embedded software. Background technique

[0002] Embedded software is the operating system and development tool software embedded in the hardware. Its relationship in the industry is reflected in: chip design and manufacturing, embedded system software, embedded electronic equipment development and manufacturing. Embedded system refers to the A dedicated computer system that performs an independent function. It consists of a series of microelectronic chips and devices including microprocessors, timers, microcontrollers, memories, sensors, etc., as well as micro-operating systems and control application software embedded in memories, to achieve real-time control, monitoring, management, etc. , mobile computing, data processing and other automated processing tasks.
