Good autgmentability.
In another embodiment, as a example by it there are two embedded systems in embedded device, the disclosure is provided
The method of embedded system upgrading carries out explanation explained in detail.As shown in Fig. 2 the method for embedded system upgrading includes：
In step s 201, the current system version with startup ability of determination in already present two embedded systems
This number highest embedded system is used as the first embedded system to be launched, and starts the first embedded system；
For the step, before this step is performed, logical partition is carried out to the storage media of embedded device in advance, with
The each self-corresponding storage media subregion of to be implanted two embedded system is obtained, so as to divide in corresponding storage media subregion
Corresponding embedded system is not implanted into.
Wherein, when the storage media to embedded device carries out logical partition, the quantity of the storage media subregion for obtaining
Concretely 8, certainly, outside the number of partitions divider value 8 of storage media, can also be other numerical value, for example, 16 or 32 etc.
Deng the present embodiment is not especially limited to the quantity of storage media subregion, depending on the number of visual embedded system to be implanted.
Additionally, the size of each storage media subregion can be the same or different.For example, the less storage matchmaker of memory space can be divided
Matter subregion, starts mark for storing a class；The larger storage media subregion of memory space can be also divided, it is embedding for storing two
The associated documents of embedded system.Wherein, the big I of the less storage media subregion of memory space is 64 kilobytes；Memory space
The size of larger storage media subregion concretely 4 gigabit.Certainly, the little storage media subregion of memory space and memory space
The size of big storage media subregion in addition to above-mentioned numerical value, can also be other numerical value, such as 32 kilobytes or 2 gigabits, this reality
Apply example to be equally not especially limited the size of each storage media subregion.
In another embodiment, the different storage media subregions in embedded device are implanted into corresponding embedded system respectively
The implementation of system, including but not limited to：By the kernel image file and root file system image file of two embedded systems
It is respectively written into corresponding storage media subregion；And two embedded systems are write in other storage media subregions
BootLoader。
Wherein, in embedded device, presence (preserves into disk file shape to the kernel of embedded system in the form of a file
Formula), i.e. kernel image file；In embedded device, equally presence (preserves into disk text to root file system in the form of a file
Part form), i.e. root file system image file.Further, since the effect of the BootLoader of each embedded system and program
Code is consistent, therefore, when the kernel image file and root file system image file of two embedded systems is write, it is only necessary to
Two embedded systems of write just can be actuated for control, save storage so as to reach by one BootLoader of write
The purpose in space.
Except above-mentioned in addition to the different storage media subregions of embedded device write the mode of corresponding embedded system, also
Other writing modes, the present embodiment can be taken to be not especially limited this.
In another embodiment, it is current with startup energy in order to determine in already present two embedded systems
, used as the first embedded system to be launched, the method that the present embodiment is provided is also for the system version highest embedded system of power
Start mark, the second startup including setting first to identify and the 3rd startup mark, and start mark, the second startup by first and identify
And the 3rd start mark and be respectively written into step in the storage media subregion of embedded device.
Wherein, first starts mark, can be identified with symbol flag_where_reboot, be opened for current subsystem
For dynamic, for representing whether carried out system upgrade in the upper embedded system for once starting；The present embodiment is with flag_
Where_reboot=1 represents " having carried out system upgrade in the upper embedded system for once starting "；flag_where_
Reboot=0 represents " not carrying out system upgrade in the upper embedded system for once starting ".
Second starts mark, can be identified with symbol flag_last_success, starts to come for current subsystem
Say, for identifying the last system for successfully starting up is which system in two embedded systems；For example, if with system 1
Identify two embedded systems of write with system 2 respectively, can be with flag_last_success=0 marks in the present embodiment
The system for once successfully starting up is system 1；It is to be that the last system for successfully starting up is identified with flag_last_success=1
System 2.
3rd starts mark, can be identified with symbol flag_last_boot_try, be opened for embedded system for the first time
For dynamic, can start when mark determines embedded system initial start-up which embedded system started according to the 3rd.
For example, if identifying two embedded systems of write with system 1 and system 2 respectively, can be with flag_last_ in the present embodiment
Boot_try=0 answers activation system 1 when representing embedded system initial start-up；Represent embedding with flag_last_boot_try=0
Activation system 2 is answered during embedded system initial start-up.
It should be noted that above-mentioned 3rd startup mark is upgraded successfully in embedded system or embedded system normally starts
When, will not play a role.When embedded system initial start-up or during embedded system startup separator, can just play a role.
It is in order to which system should be started when determining and starting first, and when it is determined that the system start-up fails it is another to continue to start
Individual system, prevents repeatedly start fault embedded system and arranges.Its concrete effect can combine program in subsequent step
Code is explained.
In another embodiment, after above three startup mark is set, respectively three start mark and assign initial values
0.When the storage media subregion write above three to embedded device starts mark, in order to prevent to storage media subregion
Middle write is broken down in starting identification procedure, so as to the startup indicating failure for causing to be successfully written, so above three is opened
Dynamic mark is write in the storage media subregion of three files for being different from two embedded systems of storage respectively.
Three based on above-mentioned setting start mark, and the determination in already present two embedded systems currently has and starts
Implementation of the system version highest embedded system of ability as the first embedded system to be launched, including but not
It is limited to：
According to first start mark determine under the upper embedded system for once starting it is whether not actuated embedded to other
Formula system is upgraded；
If under the upper embedded system for once starting, the embedded system not actuated to other is upgraded, root
Start the embedded system that mark determines last upgrading according to second, and the embedded system after last upgrading is defined as working as
The front system version highest embedded system with the ability of startup, and by the current system version number with startup ability most
High embedded system is used as the first embedded system to be launched.
If the embedded system not actuated to other is not upgraded under the upper embedded system for once starting, will
The last embedded system for starting is defined as the currently system version highest embedded system with startup ability, and will
The current system version highest embedded system with startup ability is used as the first embedded system to be launched.
In another embodiment, in already present at least two embedded system, it is determined that currently having startup ability
System version highest embedded system as the first embedded system to be launched, including but not limited to：
If the embedded device with already present at least two embedded system is initial start-up, open according to the 3rd
The currency of dynamic mark determines current first embedded system to be launched.
Two embedded systems are identified respectively with system 1 and system 2 now, the first startup is designated flag_where_
Reboot, and the value of flag_where_reboot is 0 or 1, the second startup is designated flag_last_success, and flag_
The value of last_success is 0 or 1, the 3rd startup mark flag_last _ boot_try, and flag_last_boot_try
As a example by being worth for 0 or 1, the current system version number with startup ability is determined in already present two embedded systems to above-mentioned
Highest embedded system is visually illustrated as the first embedded system to be launched.Wherein, each starts mark
The concrete meaning that the numerical value of knowledge is represented is introduced in the previous section of this step, and here is omitted.Comprise the following steps that：
The first step：Determine that the first startup identifies the currency of flag_where_reboot；
Second step：If the currency of flag_where_reboot is 1, by the currency of flag_where_reboot
0 is assigned, and continues to determine the second currency for starting mark flag_last_success；
3rd step：In second step, if the currency of flag_last_success is 1, it is determined that current to be launched
First embedded system is system 1；If the currency of flag_last_success is 0, it is determined that currently to be launched first
Embedded system is system 2；
4th step：In the first step, if the currency of flag_where_reboot is 0, continue to determine that second starts
