It can be applied to built-in terminal, this method may include steps of:
Step 501: after the built-in terminal starts and powers on, using predetermined guidance loading system, reading mesh
Mark subregion.
It in the embodiment of the present invention, powers on after built-in terminal booting, is read using bootloader (guidance loading system)
Target partition in memory is preset, bootloader is equivalent to BIOS (Chinese: basic input output system；English:
Basic Input Output System), illustratively, guidance loading system bootloader is kernel in an operating system
The one section of small routine run before operation carries out hardware initialization to built-in terminal by this section of small routine.For example, obtaining embedding
Enter the memory size information etc. of formula terminal, adaptation state is adjusted to correspondence.In technical solution according to the present invention,
Bootloader can carry out reading data to the target partition in current memory, further to determine that target is grasped according to below step
Make system, to complete the starting of built-in terminal.
It should be noted that bootloader, which is generally based on particular hardware platform, to be come in fact for embedded system
Existing, therefore, none is suitable for the general bootloader of all embedded systems, that is, for different places
Reason device framework has different bootloader.Built-in terminal according to the present invention preferably regards networked terminals, can also
To be the terminal device using Ethernet (internet).
Step 502: according to the numerical value of target partition, determining the destination OS that will start on built-in terminal.
Wherein, destination OS includes the first operating system or the second operating system, and the numerical value of target partition is to use
In the numerical value of instruction destination OS.
Illustratively, for built-in terminal, the first operating system in destination OS can operate for Linux
System or Android operation system, corresponding, the second operating system can be Android operation system or (SuSE) Linux OS.
That is, the flag bit for being used to indicate destination OS can be preset in target partition, i.e., by the flag bit
Numerical value of the numerical value as target partition, so that different numerical value of the bootloader according to this flag bit, are embedded end
End is corresponding to determine that its destination OS is (SuSE) Linux OS or Android operation system.
In a particular application, such as Android operation system can be set to the first operating system, corresponding target is divided
The numerical value in area is 1 (the first default value), sets the second operating system, corresponding target partition for (SuSE) Linux OS
Numerical value be 0 (the second default value).Preferably, which may include:
In the case where the numerical value of target partition is the first default value, determine that destination OS is the first operation system
System；
In the case where the numerical value of target partition is the second default value, determine that destination OS is the second operation system
System.
That is, destination OS is determined as Android operation system when the numerical value (flag bit) of target partition is 1
System；Conversely, destination OS is then determined as (SuSE) Linux OS when the numerical value of target partition is 0.
Step 503: starting destination OS on built-in terminal.
In a particular application, that is, the destination OS according to determined by step 502 will with starting the built-in terminal
Built-in terminal operates in the environment of destination OS.
In conclusion the embodiment of the present invention can be applied on built-in terminal, after built-in terminal starts and powers on,
Using predetermined guidance loading system, target partition is read；According to the numerical value of target partition, determination will be in built-in terminal

Step 504: obtaining the setting for target partition to be arranged and instruct.
Wherein, setting instruction is for setting default value for the numerical value of target partition.
Illustratively, based on the embodiment described of Fig. 5, destination OS is determined according to the numerical value of target partition, embedding
Enter after starting destination OS in formula terminal, can inquire whether the user needs to carry out operating system after start completion
Switching.Such as, if (SuSE) Linux OS is switched to Android operation system, or whether is cut Android operation system
It is changed to (SuSE) Linux OS, that is, according to the demand of user, after obtaining corresponding setting instruction, to target partition pair
The flag bit answered is configured, that is, carries out the operation of below step.
Step 505: being instructed in response to setting, judge whether the numerical value of target partition is consistent with default value.
Illustratively, setting instruction is therefore the instruction for the numerical value of target partition to be arranged in default value is sentenced first
Whether the numerical value of disconnected current goal subregion is consistent with default value.Under unanimous circumstances, the numerical value without target partition is more
Change, that is, carry out the operation of step 506, directly the corresponding destination OS of operation default value；Otherwise, in target partition
Numerical value and default value it is inconsistent in the case where, then need the numerical value for carrying out target partition to reset, that is, walked
Rapid 507 operation sets default value for the numerical value of target partition, and restarts built-in terminal, so that the embedded end
End operates under destination OS corresponding to default value.
Step 506: under the numerical value of target partition and default value unanimous circumstances, operational objective operating system.
Illustratively, when the numerical value of target partition is consistent with default value, illustrate the current operation system of built-in terminal
It is consistent with the desired operating system of user, it can continue to operate in built-in terminal under destination OS, without carrying out mesh
Mark the change of the numerical value of subregion.
Step 507: in the case where the numerical value of target partition and default value are inconsistent, the numerical value of target partition being arranged
For default value, to restart built-in terminal.
Illustratively, when the numerical value of target partition and default value are inconsistent, illustrate the current operation system of built-in terminal
It unites inconsistent with the desired operating system of user, needs to switch over.Such as the operating system that built-in terminal is currently started
For (SuSE) Linux OS, that is to say, that the numerical value of target partition is 0, and it is 1 that the default value being arranged needed for instruction, which is arranged, then
It needs for the operating system of built-in terminal to be switched under Android operation system representated by default value 1, that is, restarts embedding
Enter formula terminal, to read the numerical value of target partition using bootloader, and since the numerical value of target partition can be true for 1
Surely the destination OS of the built-in terminal after restarting is Android operation system.

Step 509: target partition is set on built-in terminal.
Illustratively, it in order to realize that the dual system on built-in terminal switches, needs to carry out on built-in terminal preparatory
Setting the first operating system and the system files subregion such as the corresponding startup program of the second operating system and data content is arranged
In the memory of built-in terminal, to guarantee the normal starting of destination OS.It should be noted that the data of operating system
The memory stored belongs to the memory space without clear operation after restart, to guarantee that operating system after restart opens
It is dynamic.In addition, open up a target partition in the memory, for store with flag bit corresponding to destination OS, with true
Protecting built-in terminal can be in the operation under destination OS.
Optionally, referring to Fig. 8, a kind of specific steps stream of the switching method embodiment of operating system of the invention is shown
Cheng Tu starts destination OS described in step 503 on built-in terminal, can specifically include following steps:
Step 5031: according to destination OS, generating the corresponding environmental parameter of destination OS.
In a particular application, build environment parameter (bootargs), such as object run are corresponded to according to destination OS
When system is Android operation system, then the bootargs for generating Android operation system is corresponded to；It is Linux behaviour in destination OS
When making system, then the bootargs for generating (SuSE) Linux OS is corresponded to, and then be convenient for the operation of below step.
Step 5032: according to environmental parameter, starting the kernel of destination OS.
Step 5033: the initialization process in starting kernel, with carry partition data corresponding with destination OS.
