Abstract
The invention discloses a method and system for generating and compounding an embedded firmware differential upgrading file. The method comprises the following steps that A, the differential updating file is generated, different data bytes of existing firmware and to-be-updated firmware of a terminal are obtained by comparing the existing firmware of the terminal and the firmware needing to be updated, a removal package and an adding package are obtained with the data bytes as units, and the removal package and the adding package are compounded into an upgrading package; B, the upgrading package is downloaded; C, the differential upgrading file is compounded, the upgrading package is analyzed into the removal package and the adding package, and the removal package, the adding package and the existing firmware of the terminal are compounded into the firmware needing to be updated. The same data bytes and the different data bytes in the two files are distinguished, data are packaged to upgrade the upgrading package in a differential mode, the upgrading file is compressed, upgrading time is shortened, resource consumption is reduced, and fast upgrading of the firmware is achieved.
Description
Technical field
The present invention relates to by air interface technologies, embedded firmware is upgraded to upgrading, a kind of specifically generation method of embedded firmware difference upgrade file, and by synthetic method and the system of the synthetic corresponding embedded firmware of difference upgrade file.
Background technology
Along with the rise of Internet of Things industry, the development of low-consumption wireless communication technology bluetooth and zigbee, demand is maked rapid progress, and needs to upgrade to embedded product fast and effectively.The firmware upgrade technology of traditional a pair of same form, escalation process takies too many resource, expends data traffic huge, and escalation process is slow, more and more can not meet client's demand.
Therefore there is a kind of mode of upgrading by difference bag, adopted by increasing people.But original difference bag upgrading mode, for large-scale embedded software products such as mobile phones, can not be applicable to the product of the wireless communication technology such as bluetooth and the zigbee air interface upgrading based on low rate low-power consumption.As the application number patent of invention " AKU generates method and the terminal of method and system, the upgrading of living document difference " that is 201210209785.4, this upgrading mode is for large-scale embedded system firmware, this firmware tape file system, what upgrading can be controlled differentiation is each file.
As shown in Figure 1, the thought of this patent packing AKU is, if had this file in terminal (mobile phone), when packing AKU, just need not be packed into account, if there is no this file, he goes inside just it being bundled to AKU.Like this, because most of file is identical, do not change, different files is just fewer, so the AKU of packing is also smaller, can shortens to a certain extent update time and reduce resource consumption.
This upgrading thought is more macroscopical.Just look like a bookcase, we will upgrade the books above bookcase, will see name and the front cover of books, just needs can be removed to the books that come and just lift down, and need the books that upgrade just to put up.
Although this upgrading thought shortens to a certain extent update time and reduces resource consumption, but do not find yet the most effectively scheme, because Single document is not minimum data unit, it comprises a large amount of byte datas Single document, in the time needing just some byte data of renewal in escalation process, it is also extremely slow and waste resource upgrading whole file, the product of especially upgrading in bluetooth and the zigbee etc. of low rate low-power consumption wireless communication technology air interface.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of embedded firmware difference upgrade file of realizing quick upgrading and generate and synthetic method and system.
The technical solution used in the present invention is:
The file generated of embedded firmware difference upgrading and synthetic method, comprise the following steps:
The generation of A, difference upgrade file: compare the two different data byte according to the existing firmware of terminal and the firmware that need to upgrade, obtain delete bag and increase bag taking data byte as unit, deletion is wrapped and increased inclusion becomes AKU;
B, download described AKU;
Synthesizing of C, difference upgrade file: described AKU is resolved to and deletes bag and increase bag, wrap deleting, increase and wrap and the synthetic firmware that needs renewal of the existing firmware of terminal.
Further, in described steps A, deleting content that handbag contains and be the existing firmware of terminal has and needs the firmware upgrading not have, and increasing the content that handbag contains is that the existing firmware of terminal does not have to need the firmware of renewal to have.
Further, in described step C the existing firmware of terminal to participate in synthetic content be the existing firmware of terminal and need the two identical part of firmware of upgrading.
Wherein, described AKU also comprise AKU length, AKU type, delete packet length, increase packet length, firmware updating check value, file verification.
Further, after described step B has downloaded, described step C resolves before AKU and is provided with a checking routine, when verification succeeds enters step C.
The present invention also comprises and the file generated of a kind of embedded firmware difference upgrading of said method based on same inventive concept and synthetic system, comprise at least one server and/or main process equipment end and with server and/or the mutual at least one terminal of main process equipment end;
This server and/or main process equipment end are used for the generation of difference upgrade file: compare the two different data byte according to the existing firmware of terminal with the firmware that needs renewal, obtain taking data byte as unit and delete bag and increase bag, deletion is wrapped and increased inclusion becomes AKU;
This terminal comprises a protocol stack module, an AKU parsing module, a firmware Knockdown block, a firmware upgrade module, wherein, protocol stack module and server and/or main process equipment end are alternately to download described AKU, AKU parsing module resolves to described AKU to delete bag and increase bag, firmware Knockdown block wraps, increases the existing firmware of bag and terminal and synthesizes the firmware that needs renewal by deleting, firmware upgrade module is the firmware that needs renewal by existing terminal firmware upgrade.
Further, the content that described deletion handbag contains is that the existing firmware of terminal has and needs the firmware upgrading not have, and increasing the content that handbag contains is that the existing firmware of terminal does not have to need the firmware of renewal to have.
Further, to participate in synthetic content be the existing firmware of terminal to the existing firmware of described terminal and need the two identical part of firmware of upgrading.
Wherein, described AKU also comprise AKU length, AKU type, delete packet length, increase packet length, firmware updating check value, file verification.
Further, download AKU complete after, resolve before AKU and be provided with a checking routine, when verification succeeds enters parsing link.
Beneficial effect of the present invention:
The present invention proposes a kind of embedded firmware difference upgrade file and generates and synthetic method and system, by distinguish two files in and different data byte, carry out the AKU that packing data carries out difference upgrading, compression upgrade file size, shorten update time and reduce resource consumption, realizing the quick upgrading of firmware.
