In another embodiment, to exist two embedded systems as example in embedded device, the method for the embedded system upgrading that the disclosure is provided is at length explained.As shown in Figure 2, the method for embedded system upgrading comprises:
In step S201, in already present two embedded systems, determine that embedded system that the current system version with startup ability is number the highest is as the first embedded system to be started, and start the first embedded system;
For this step, before carrying out this step, in advance the storage media of embedded device is carried out to logical partition, to obtain the each self-corresponding storage media subregion of two embedded systems to be implanted, thereby implant respectively corresponding embedded system in corresponding storage media subregion.
Wherein, in the time that the storage media of embedded device is carried out to logical partition, the quantity of the storage media subregion obtaining specifically can be 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., the present embodiment is not done concrete restriction to the quantity of storage media subregion, is determined by the number of embedded system to be implanted.In addition, the size of each storage media subregion can be the same or different.For example, can divide the storage media subregion that storage space is less, be used for storing a class and start mark; Also can divide the storage media subregion that storage space is larger, be used for storing the associated documents of two embedded systems.The size of the storage media subregion that wherein, storage space is less can be 64 kilobyte; The size of the storage media subregion that storage space is larger specifically can be 4 gigabits.Certainly, the size of the storage media subregion that the storage media subregion that storage space is little and storage space are large is except above-mentioned numerical value, can also be other numerical value, for example 32 kilobyte or 2 gigabits, the present embodiment is not done concrete restriction equally to the size of each storage media subregion.
In another embodiment, the implementation of implanting respectively corresponding embedded system at the different storage media subregions of embedded device, includes but not limited to: the kernel image file of two embedded systems and root file system image file are write respectively to corresponding storage media subregion; And in other storage media subregions, write the BootLoader of two embedded systems.
Wherein, there is (preserving into disk file form), i.e. kernel image file in the kernel of embedded system form with file in embedded device; In embedded device, there is (preserving into disk file form), i.e. root file system image file with the form of file equally in root file system.In addition, because effect and the program code of the BootLoader of each embedded system are all consistent, therefore, in the time writing the kernel image file of two embedded systems and root file system image file, only need to write a BootLoader, just can control the startup of write two embedded systems, thereby reach the object of saving storage space.
Except the above-mentioned different storage media subregions at embedded device write the mode of corresponding embedded system, can also take other writing modes, the present embodiment is not done concrete restriction to this.
In another embodiment, in order to determine in already present two embedded systems that embedded system that the current system version with startup ability is number the highest is as the first embedded system to be started, the method that the present embodiment provides also comprises that the first startup mark, the second startup mark and the 3rd startup are set to be identified, and the first startup mark, the second startup mark and the 3rd startup are identified to the step in the storage media subregion that writes respectively embedded device.
Wherein, first starts mark, can identify by symbol flag_where_reboot, starts for current subsystem, whether has carried out system upgrade for being illustrated in the last embedded system starting; The present embodiment represents " in the upper embedded system once starting, having carried out system upgrade " with flag_where_reboot=1; Flag_where_reboot=0 represents " in the upper embedded system once starting, not carrying out system upgrade ".
Second starts mark, can identify by symbol flag_last_success, start for current subsystem, and be which system of two embedded systems for identifying the last successful system starting; For example, if identify respectively with system 1 and system 2 two embedded systems that write, in the present embodiment, can the last successful system starting of flag_last_success=0 mark be system 1; The system starting with the last success of flag_last_success=1 mark is system 2.
The 3rd starts mark, can identify by symbol flag_last_boot_try, for embedded system initial start-up, can start when mark is determined embedded system initial start-up to start which embedded system according to the 3rd.For example, if identify respectively with system 1 and system 2 two embedded systems that write, while can flag_last_boot_try=0 in the present embodiment representing embedded system initial start-up, should start system 1; While representing embedded system initial start-up with flag_last_boot_try=0, should start system 2.
It should be noted that, above-mentioned the 3rd startup is identified at when embedded system upgrades successfully or embedded system normally starts, and all can not play a role.In the time of embedded system initial start-up or when embedded system starts fault, just can play a role.It is in order to determine while starting first to start which system, and continues to start another system in the time that definite this system starts unsuccessfully, for preventing what repeatedly start fault embedded system from arranging.Its concrete effect meeting is explained in conjunction with program code in subsequent step.
In another embodiment, setting after above-mentioned three startup marks, be respectively three and start mark initializes 0.In the time that the storage media subregion to embedded device writes above-mentioned three startup marks, in order to prevent breaking down in write-enable identification procedure in storage media subregion, thereby the startup that causes successfully writing mark lost efficacy, write on respectively in three storage media subregions that are different from the file of storing two embedded systems so start mark by above-mentioned three.
Start mark based on three of above-mentioned setting, in already present two embedded systems, determine embedded system that the current system version with startup ability the is number the highest implementation as the first embedded system to be started, include but not limited to:
Determine that according to the first startup mark the embedded system whether other not being started upgrades under the upper embedded system once starting;
If the embedded system under the upper embedded system once starting, other not being started is upgraded, determine the embedded system of last upgrading according to the second startup mark, and the embedded system after last time upgrading is defined as to the current system version number the highest embedded system with startup ability, and using embedded system number the highest the current system version with startup ability as the first embedded system to be started.
If the embedded system other not being started under the upper embedded system once starting is upgraded, the embedded system last time being started is defined as the current system version number the highest embedded system with startup ability, and using embedded system number the highest the current system version with startup ability as the first embedded system to be started.
In another embodiment, in already present at least two embedded systems, determine that embedded system that the current system version with startup ability is number the highest, as the first embedded system to be started, includes but not limited to:
If having the embedded device of already present at least two embedded systems is initial start-up, determine the first embedded system current to be started according to the 3rd currency that starts mark.
Now identify respectively two embedded systems with system 1 and system 2, 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 the value of flag_last_success is 0 or 1, the 3rd starts mark flag_last_boot_try, and the value of flag_last_boot_try is 0 or 1 for example, to above-mentioned in already present two embedded systems determine the current system version number the highest embedded system with startup ability explain visually as the first embedded system to be started.Wherein, each concrete meaning that starts the numeric representation of mark is introduced in the previous section of this step, repeats no more herein.Concrete steps are as follows:
The first step: the currency of determining the first startup mark flag_where_reboot;
Second step: if the currency of flag_where_reboot is 1, the currency of flag_where_reboot is composed to 0, and continue to determine that second starts the currency of mark flag_last_success;
The 3rd step: in second step, if the currency of flag_last_success is 1, determine that the first embedded system current to be started is system 1; If the currency of flag_last_success is 0, determine that the first embedded system current to be started is system 2;
The 4th step: in the first step, if the currency of flag_where_reboot is 0, continue to determine that second starts the currency of mark flag_last_success;
The 5th step: in the 4th step, if the second currency that starts mark flag_last_success is 1, start system 2; If the second currency that starts mark flag_last_success is 0, continue to determine that the 3rd starts the currency of mark flag_last_boot_try;
The 6th step: in the 5th step, if the 3rd currency that starts mark flag_last_boot_try is 0, starts system 1, and flag_last_boot_try is composed to 1; If the 3rd currency that starts mark flag_last_boot_try is 1, start system 2.
The implementation of the above-mentioned first step to the six steps, also can be realized by program code, and program code is specific as follows:
In another embodiment, start the implementation of the first embedded system, include but not limited to:
The kernel image file of first embedded system of storing in storage media corresponding the first embedded system is loaded in internal memory and is moved, and the root file system image file of carry the first embedded system.
Wherein, carry refers to an equipment (normally memory device, for example, storage media) is articulated in an already present catalogue.While wanting the file in accessing storage device, the subregion at file place need be mounted in an already present catalogue, then visit memory device by accessing this catalogue.
For root file system image file that can successful carry the first embedded system, before the root file system image file of carry the first embedded system, also be required to be each storage media subregion address is set respectively, and set up the mapping table of storage media subregion and address.Thereby search this mapping table and just can find the place storage media subregion of the root file system image file of the first embedded system according to storage media partition address; And then the root file system image file of successful carry the first embedded system.
In step S202, under the first embedded system, obtain system upgrade bag, system upgrade bag is write in storage media subregion corresponding to the second embedded system, complete the upgrading to the second embedded system.
For this step, when embedded device is set up with the exploitation main frame of far-end after network connection, exploitation main frame is as the promoter of system upgrade task, detecting while there is new system upgrade bag, just initiatively to embedded device transmitting system upgrading order, to indicate embedded device to carry out system upgrade.And in order to make the clear and definite system upgrade bag that when obtains of embedded device, the method that the present embodiment provides also comprises the step that judges whether to receive system upgrade indication.
About the implementation that judges whether to receive system upgrade indication, include but not limited to:
Judge whether to receive the system upgrade order that comprises specific character that exploitation main frame sends; If receive the system upgrade order that comprises specific character, send the reply message of confirming to carry out system upgrade to exploitation main frame; If do not receive the system upgrade order that comprises specific character, executive system updating operation not.
Wherein, reply message and specifically can be ACK(Acknowledgement, acknowledge character) message, certainly, reply message except ACK message, can also be the message of other types, the present embodiment is not done concrete restriction to the type of replying message.
In another embodiment, under the first embedded system, obtain the implementation of system upgrade bag, include but not limited to:
The first embedded system receives each packet that far-end exploitation main frame sends, often receive after a packet, exploitation main frame to far-end sends acknowledge message, receive the checking data bag of the exploitation main frame transmission of far-end simultaneously, if packet verification is errorless, judge and successfully obtain this packet, and receive next packet to exploitation main frame back-checking result and the continuation of far-end; If packet verification is wrong, judgement does not get this packet.
Wherein, each packet is split as multiple data cells of regular length by the kernel image file of latest edition and root file system image file in advance by the exploitation main frame of far-end, and forms packet take each data cell as core.Wherein, packet comprises data packet head mark, command header, packet sequence, data cell, CRC check code, packet tail tag will and overall budget number etc.
Getting after system upgrade bag, whether complete for confirming the content of the system upgrade bag getting, to guarantee that the system upgrade bag that follow-up basis gets successfully upgrades to system, the method that the present embodiment provides also comprises the step of system upgrade bag being carried out to verification.
Wherein, system upgrade bag is carried out to the implementation of verification, includes but not limited to:
Whether the bag number of confirming the packet receiving is consistent with the overall budget number comprising in each packet; If the bag number of the packet receiving is consistent with the overall budget number comprising in each packet, to system upgrade bag verification succeeds, determine the content intact of the AKU getting.
Certainly, except above-mentioned mode of system upgrade bag being carried out to verification, also can take other verification modes, the present embodiment is not done concrete restriction to this.
Alternatively, after to system upgrade bag verification succeeds, system upgrade bag can be written in storage media subregion corresponding to the second embedded system.Wherein, system upgrade bag is written to the implementation in storage media subregion corresponding to the second embedded system, includes but not limited to:
The original packet of storing in storage media subregion corresponding the second embedded system is wiped, the system upgrade bag obtaining is written in storage media subregion corresponding to the second embedded system.Because system upgrade bag comprises kernel image file and the root file system image file after upgrading, system upgrade bag is write in storage media subregion corresponding to the second embedded system, comprising: the kernel image file after the upgrading that system upgrade bag is comprised and root file system image file write in storage media subregion corresponding to the second embedded system.By upgrading after kernel image file and root file system image file write storage media subregion corresponding to the second embedded system in after, owing in the first embedded system, the second embedded system being upgraded, therefore, the currency of the first startup mark need be upgraded, be updated to flag_where_reboot=1 by flag_where_reboot=0.
Alternatively, because the version of system upgrade bag is better than the version of the first embedded system, in order to guarantee the system works performance of embedded system, need to carry out embedded system switching, control the first embedded system out of service, and start the second embedded system after upgrading.Control the kernel image file of the first embedded system by BootLoader out of service.After control the first embedded system is out of service, restart the second embedded system.
Wherein, start the implementation of the second embedded system after upgrading, include but not limited to:
The kernel image file that the system upgrade bag of storing in storage media corresponding the second embedded system is comprised is loaded in internal memory and moves, and the root file system image file that comprises of carry system upgrade bag.
In another embodiment, in the time of the second embedded system starting after upgrading, the method that the present embodiment provides also comprises the step that judges whether successfully to start the second embedded system after upgrading; If successfully start the second embedded system after upgrading, the currency of the second startup mark and the 3rd currency that starts mark are upgraded.
