Description
Technical field
The present invention relates to a kind of update method and system of Embedded Double system, more particularly to one kind in bootloader
（BootLoader is exactly the one section of small routine run before operating system nucleus operation.By this section of small routine, we can be with
Initiating hardware equipment, memory headroom mapping graph is established, so as to take the hardware environment of system to a proper states, so as to
Correct environment is got out for final call operation system kernel.In embedded systems, generally not as BIOS（Substantially it is defeated
Enter output system）Such firmware program（Note, some embedded type CPUs can also embed one section of short and small startup program）, therefore it is whole
The loading of individual system starts task and just completed completely by BootLoader.
Background technology
With information-based, intelligent, networking development, embedded system technology has obtained wide development space, mesh
Before be widely used in the multiple fields such as network service, consumer electronics, manufacture, safety-protection system, Industry Control, military affairs.Now should
Enriched constantly with the function of software so that our stability requirement more and more highers to operating system, but when system runs into not
During reversible destruction, it would be desirable to which a kind of simple and effective way can rapid recovery system operation.
It is at present dual system using commonplace method, but the defects of certain be present in current Dual System Design, than
Such as existing dual system update mode is complicated, to storage device（A such as flash（Flash memory））Subregion and complex operation, this is just
So that technical staff will be also longer in face of the operation of complexity, the time of cost when updating system image.Therefore, it is necessary to a kind of behaviour
Make simply and easily mode and overcome above mentioned problem.
The content of the invention
The technical problem to be solved in the present invention be in order to overcome the update mode of Embedded Double system in the prior art it is complicated,

It is small.
The storage device 1 is a flash equipment in the present embodiment.
Next, the technical side of the present invention is further illustrated by taking the entire flow of the startup of an Embedded Double system as an example
Case, infra for the facility in description, dual system is referred to as system A and system B.
The Embedded Double system includes the image file of Embedded Double system（Whether system A and system B is total in the present invention
With a bootloader image file）, and Booting sequence includes the system of default system bootstrap technique and update mode
Bootstrap technique.Described image file is by startup message part, bootloader mirrored portions and kernel and its root file mirrors
Part forms（The operating system software for functioning as PC of both kernel and its root file mirrors altogether）.Start information
Part includes the address space size of flash configuration informations, bootloader mirror image initial addresses and occupancy, and system image starts
The address space size that address, system image check value and system image take（Herein, system image refer to kernel and
Its root file mirrors）.
Described flash configuration informations include flash equipment partition informations, system image A startup address and system mirror
As B startup address.
Described flash equipment includes bootloader subregions（Bootloader subregions are used to deposit bootloader mirrors
As file）, start information subregion, system image A subregions, system image B subregions, environmental variance subregion（Wherein environmental variance point
Area is used for some parameters that storage system starts）And reserved partition.
The flow of described default system bootstrap technique is to obtain the information in information subregion on activation system first,
Judge that Systematic selection starts from which mirrored partition, then read and start corresponding address and the mirror image of starting in information
Check value.If the check value for verifying mirror image is correct, program will jump at the startup address read and go to run；If no
Correctly, then select another mirrored partition to start, and read to start and start address corresponding to its in information subregion, verify mirror image
Check value, if correctly, program to read startup address at go to run.If two systems all can not normally start, or
The check value that person verifies mirror image is all incorrect, and system enters the renewal order to be entered such as command mode into the system of update mode
Guiding.
The system boot method of described update mode includes more newer command, generation patterns and System guides mode.Wherein
Generation patterns include starting message part generation patterns, and bootloader mirror image generation patterns, kernel and its root file mirrors are more
New model, whole mirror image generation patterns.The system boot method detailed process of update mode is as follows, when system enters command mode
Afterwards, after inputting more newer command and its generation patterns, judge that it belongs to above-mentioned any generation patterns：
If a) belonging to whole mirror image generation patterns, the flash equipment partition informations of flash configuration informations are read, will
Flash equipment is divided into bootloader subregions, starts information subregion, system image A subregions, system image B subregions, environmental variance
Subregion and reserved partition（When needing other subregions, the flash configurations of the image file of Embedded Double system need to be only remodified
Then information reuses the system boot method guiding system of update mode）, then bootloader mirror images are write
Bootloader subregions, the write-in of flash configuration informations start information subregion, kernel and its root file mirrors writing system mirror image A
Subregion and system image B subregions.
B) if starting message part generation patterns, flash configuration informations need to only be write and starts information subregion.
C) if bootloader mirror image generation patterns, only bootloader mirror images need to be write bootloader points
Area.
D), need to be by kernel and its root file mirrors writing system mirror image if kernel and its root file mirrors generation patterns
A subregions and system image B subregions.
Then restarting systems, then according to default system bootstrap technique activation system.
The invention provides the update method and system for the Embedded Double system that can be upgraded in time, and it can be with simple and flexible
Mode come update it is any required for partial image or whole mirror image, successfully solve technical staff in more new system mirror
As when faced complex operation, spend the time it is longer the problem of, improve production efficiency.And effective and reasonable make use of is deposited
Store up equipment（A such as flash）Space, be storage device section because dual system is used in conjunction with a bootloader mirror image
Many spaces are saved.The information subregion of flash equipment provides a platform for setting system starting state well simultaneously.
Although the foregoing describing the embodiment of the present invention, it will be appreciated by those of skill in the art that these
It is merely illustrative of, protection scope of the present invention is defined by the appended claims.Those skilled in the art is not carrying on the back
On the premise of principle and essence from the present invention, various changes or modifications can be made to these embodiments, but these are changed
Protection scope of the present invention is each fallen within modification.
