It describes in detail below to the embodiment of the present invention.
Referring to Fig. 1, the step flow chart for the firmware update showing in one embodiment of the invention, the firmware is more
New method includes the following steps:
Terminal can for cell phone, tablet computer, personal digital assistant (Personal Digital Assistant,
PDA), the electronic equipments such as mobile internet device (Mobile Internet Device, MID), internet of things equipment, the present invention are real
It applies example and this is not construed as limiting.
Existing system is in upgrading, at the terminal after electricity, main starting guiding module (the Primary boot of system loads
Loader, PLB), reload time starting guiding module (Second boot loader, SBL).Later, it is guided by secondary starting
Module loading power resources management module, security module and application operating system start-up loading module, and by application operating system
The kernel module etc. united under start-up loading module loading recovery mode.Due to file system (system module), air protocol mould
Block (modem module) is upgrade method file-based, is needed before upgrading to file system, air protocol module by file system
Subregion carry where system, air protocol module is read-write file system.However, when the unexpected power down of terminal, it may
Cause file system occur file lose and file system corruption situation, especially will it is file system mounted be it is read-write when, if
Unexpected power down, it is possible that the case where file system corruption, then cause terminal can not normal boot-strap.
It may cause the deficiency of file system corruption when system upgrade to reduce, upgrade file system in the present embodiment,
Air protocol module is then the mode based on image upgrade, wherein image upgrade is represented by image file writing module pair
The upgrading that can be completed in the subregion answered.
Step 100, the upgrade package target partition to be stored is determined.
In the present embodiment, since the file system in terminal has biggish memory space, file system can be multiplexed
Subregion where system, subregion where upgrade package is directly stored in file system, at this point, the subregion where file system is target
Subregion.
For example, the storage device (such as flash memory) of terminal may include several partition holdings, each partition holding is for storage pair
The file system answered, for example, terminal may include the first to the 9th partition holding, wherein starting module can be stored in the first storage
Subregion, power resources management module can be stored in the second partition holding, and security module can be stored in third partition holding, using behaviour
Making system start-up loading module can be stored in the 4th partition holding, and kernel module can be stored in the 5th partition holding, file system
It can be stored in the 6th partition holding, air protocol module can be stored in the 7th partition holding, and the 8th partition holding can be used as backup
Subregion, the mirror image of the file system for storing target partition, size is more bigger than the mirror image of the file system of target partition, the
Nine partition holdings are used for storage state parameter, size can be 1 block (BLOCK) as configuration information subregion.
Since system is subregion where the file system of root file system and user, so the storage where file system
Subregion (i.e. system subregion or the 6th partition holding) can generally occupy very large space, and therefore, the upgrade package of downloading can be with
It is multiplexed the entire space of the subregion.When downloading upgrade package, the file system mounted to be read-only of system subregion prevents other
Write operation is carried out using to it, then directly the upgrade package of downloading is stored in this subregion, in the present embodiment, upgrade package
It stores and FLASH read-write interface can be used to be stored, the mode for being not based on file is stored.In other embodiments, by
Also have the biggish space being not used by, therefore, can also deposit by upgrade package in the partition holding where air protocol module
Storage is in the partition holding where air protocol module.
In the present embodiment, if when partition holding of the target partition of upgrade package storage where file system, it may be determined that mesh
Mark subregion is the 6th partition holding；If, can when partition holding of the target partition of upgrade package storage where air protocol module
Determine that target partition is the 7th partition holding.
Step 102, the backup operation for executing the file system that the target partition is stored, by the file system
Mirror back-up is to backing up subregion.
In the present embodiment, in order to be updated to file system and air protocol module, if upgrade package is also stored in file
The 6th partition holding where system or the 7th partition holding where air protocol module, at this time, it may be necessary to the 6th storage point
The mirror image of the file system of area or the 7th partition holding carries out backup operation.
For example, then needing the content backup to the 6th partition holding when determining the 6th partition holding as target partition
It, such as will be in the mirror back-up of the 6th partition holding to backup subregion to backup subregion；When determining the 7th partition holding as mesh
When marking subregion, then need in content backup to the backup subregion to the 7th partition holding, it is such as that the mirror image of the 7th partition holding is standby
In part to backup subregion.In the present embodiment, the size for backing up subregion needs the mirror image of the file system slightly larger than target partition
Size.In addition, since file system mirror the space occupied practical than file system can be much smaller, so entire upgrading scheme is only
It needs additionally to increase the space for being slightly larger than file system mirror.If target partition size is smaller than maximum upgrade package, need
Target partition is tuned up a bit, to guarantee that target partition is bigger than maximum upgrade package.
Step 104, the state parameter of configuration partitioned storage is obtained when the terminal executes reboot operation.
The state parameter FOTA_FLAG for configuring partitioned storage can complete for triggering upgrade status, downloading beginning state, downloading
One in state, upgrading completion status and removing state.
When triggering upgrade status, 0x01 can be set by state parameter FOTA_FLAG, to indicate that terminal can be risen
Grade operation.
When downloading beginning state, 0x02 can be set by state parameter FOTA_FLAG, to indicate can detect whether distal end
The upgrade package of storage, and in remote storage upgrade package, download upgrade package.
When downloading completion status, 0x03 can be set by state parameter FOTA_FLAG, to indicate the upgrading by distal end
Local is loaded under packet；When upgrading completion status, 0x04 can be set by state parameter FOTA_FLAG, it is each to indicate to be completed
The updating operation of subregion.
In the state of removing, 0xFF can be set by state parameter FOTA_FLAG, to indicate not having to carry out updating operation.
In the present embodiment, when storage device is flash memory, configuring space size shared by subregion can be a block
(block), wherein first page in block can storage state parameter FOTA_FLAG value.
In order to enable power resources management module, security module can also be upgraded, therefore, it is necessary in power resources management
Updating operation is executed before module, security module load.Therefore, it in the present embodiment, after load time starting guiding module, is opening
In dynamic bootstrap, the state parameter of configuration partitioned storage is obtained, to execute liter according to the state parameter of configuration partitioned storage
Grade operation, and then other modules such as power resources management module, security module load can be upgraded.
In the present embodiment, after terminal is restarted, if the state parameter of configuration subregion is triggering upgrade status, expression can be right
Terminal carries out updating operation.At this point, can carry target partition file system be it is read-only.The 6th as where file system deposits
Store up subregion, the 7th partition holding where air protocol module is file system, therefore, during upgrading, to avoid except downloading
The other applications of upgrade package cause upgrading to fail to the write operation of target partition, and controllable target partition is in read-only shape
State, to forbid except write operation of the other applications to the target partition for downloading upgrade package application program.In an embodiment
In, when existing except the write operation carried out except the other applications for carrying upgrade package application program to target partition, described in control
It is exited using journey, to guarantee that the application program of only downloading upgrade package can carry out write operation to target partition.
When configuring state parameter in subregion is triggering upgrade status, after booting, the application program for downloading upgrade package can be examined
Distal end is looked into the presence or absence of upgrade package.If there are upgrade package for distal end, the state parameter of configuration subregion is set for downloading beginning state.
If upgrade package is not present in distal end, the state parameter that configuration subregion is arranged is removing state, to indicate without executing liter to terminal
Grade operation, then restarts.
In one embodiment, it is understood that there may be the case where power down occur in terminal downloads upgrade package.To avoid by terminal liter
Grade when power down and cause terminal that can not start, after terminal is restarted, if detect configuration subregion state parameter for downloading start
State, it may be determined that power down occur when terminal downloads upgrade package, at this point, the mirror image of the file system in backup subregion can be restored
To target partition, to realize the reduction of system.For example, when target partition be file system where six partition holdings when, if
Terminal detects the state parameter of configuration subregion for downloading beginning state, due to the file system of the 6th partition holding after restarting
Mirror image has backed up in backup subregion, at this point, only the 6th partition holding need to be written in the mirror image of the file system in backup subregion
, the state parameter that configuration subregion is arranged again later is removing state.In this way, when terminal is restarted again, due to file system
System has restored, and then can avoid the possibility for causing terminal that can not start due to power down in escalation process.
By upgrade package from being distally downloaded in target partition, wherein upgrade package is since the first page of the target partition
Storage.
Referring to Figure 2 together, it show the schematic diagram of the storage format of the upgrade package in the embodiment of the present invention.
Upgrade package 40 includes header information 400 and one or more mirror images 402 to be upgraded, wherein shared by header information 400
Space can be one page in flash memory, space shared by each mirror image 402 to be upgraded can be the integral multiple of page, and insufficient section is mended
0xff.Each mirror image to be upgraded 402 successively stores, can depositing according to mirror image 402 to be upgraded in upgrade package 40 when being upgraded
Storage sequence is in turn upgraded.Upgrade package may not include the mirror image of all partition holdings, for example, when file system does not need more
When new or upgrading, mirror image to be upgraded corresponding to target partition can not be included in upgrade package；If power resources management module, safety
It then may include the mirror image to be upgraded of power resources management module, security module when module needs to be updated, in upgrade package.
Also referring to Fig. 3, the schematic diagram of the storage format of the header information in upgrade package is shown in Fig. 2.Head letter
Breath 400 contain the quantity img_cnt of mirror image to be upgraded, the partition holding name img_name of each mirror image to be upgraded, each to
Upgrade image size img_size, the offset address img_addr of each mirrored storage to be upgraded and each mirror image to be upgraded
CRC (Cyclic Redundancy Check, cyclic redundancy check) refers to check value img_crc, and structural body can describe such as
Under:
After the completion of the downloading of upgrade package 40, verification operation can be executed to upgrade package 40.
The state parameter of settable configuration subregion is downloading completion status after 40 verification operation of upgrade package passes through.For example,
The header information 400 that upgrade package 40 is included can be obtained, and executes the verification behaviour of each mirror image 402 to be upgraded in upgrade package 40
Make, to obtain the comparison check value of each mirror image to be upgraded 402.Judge whether there is the comparison of at least one mirror image 402 to be upgraded
The reference check value of the corresponding mirror image to be upgraded stored in check value and the header information 400 is not identical.When in upgrade package 40
The reference school of the corresponding mirror image to be upgraded stored in the comparison check value of each mirror image to be upgraded 402 and the header information 400
Test value it is all the same when, indicate upgrade package downloading is completed, at this point, setting configuration subregion state parameter be downloading completion status.
The corresponding mirror image to be upgraded stored in the comparison check value of at least one mirror image 402 to be upgraded and the header information 400 if it exists
Reference check value it is not identical, controlling terminal execute reboot operation.When terminal is restarted, due to the state parameter in configuration subregion
To download beginning state, at this point, loading time starting module can revert to the file system mirror of backup area in subregion, then just
After normally opened machine, the application program of operation downloading upgrade package is re-downloaded.
Step 106, it if the state parameter of the configuration subregion is downloading completion status, executes and is located at the target partition
The parsing of upgrade package operates, and obtains the mirror image to be upgraded that the upgrade package is included.
In the present embodiment, parsing operation can be carried out to upgrade package in Fig. 2, so can be obtained that upgrade package included it is to be upgraded
Mirror image.
When the state parameter for configuring subregion is downloading completion status, the upgrade package 40 being stored in target partition has been indicated
By verification operation, at this point, can be upgraded according to upgrade package to system.Upgrading is read such as from first page of target partition
Then the header information of packet updates each mirror image to be upgraded of upgrade package to where respective file system according to header information
Image upgrade can be completed in subregion.
In one embodiment, if indicating that upgrade package does not upgrade successfully, at this point, can weigh in upgrade package downloading when power down
New root is upgraded according to the head description of download package.
Step 108, judge whether include the mirror image of the target partition in the mirror image to be upgraded, if so, executing step
110；If it is not, executing step 112.
Due to storing upgrade package in target partition, in order to upgrade successfully, whether target point is included for upgrade package
Mirror image to be upgraded corresponding to area is judged, if upgrade package includes mirror image to be upgraded corresponding to target partition, is needed
Adjust the sequence of image upgrade to be upgraded；If upgrade package does not include mirror image to be upgraded corresponding to target partition, can root
The mirror image to be upgraded sequence for being included according to control upgrade package upgrades the mirror image in corresponding partition holding.
Step 110, when the mirror image to be upgraded for being included according to the upgrade package updates the mirror image in corresponding partition holding,
It controls in the mirror image final updating to the target partition to be upgraded for corresponding to the target partition in the upgrade package.
In one embodiment, if target partition is the 6th partition holding where file system, if containing in upgrade package
Mirror image to be upgraded corresponding to 6th partition holding, at this time, it may be necessary to finally execute the include in upgrade package the 6th storage point
The update operation of mirror image to be upgraded corresponding to area, is such as finally updated to the 6th for mirror image corresponding to the 6th partition holding and stores
Subregion.
In the present embodiment, when being upgraded according to the sequence of header information in upgrade package, in the to be upgraded of performance objective subregion
When the upgrading of mirror image, the controllable mirror image to be upgraded for including target partition for upgrade package is updated to the backup subregion and target point
Area, and the state parameter of configuration subregion is set for upgrading completion status.In one embodiment, it is understood that there may be configure subregion in setting
State parameter be upgrading completion status before when power down the case where, can be held since step 104 again after terminal is restarted
Row, re-starts updating operation.
For example, in upgrade package include three Coutinuous stores mirror image to be upgraded, respectively positioned at first position first to
Upgrade image (corresponding first partition holding), positioned at the second mirror image (corresponding 6th partition holding) to be upgraded of the second position and position
In the third of the third place mirror image to be upgraded (corresponding second partition holding), wherein the second mirror image to be upgraded is corresponding target point
The mirror image to be upgraded in area.At this point, when executing updating operation, it is at the first time, executing that the first image upgrade to be upgraded is corresponding extremely
After first partition holding, when executing the second mirror image to be upgraded of update in the second time, since the second mirror image to be upgraded will update
Partition holding be target partition, at this point, can skip the upgrading of the second mirror image to be upgraded, execute the liter of third mirror image to be upgraded
Grade, is such as updated to the second partition holding for third mirror image to be upgraded；After the completion of third image upgrade to be upgraded, then last execution
Second mirror image to be upgraded is such as updated in backup subregion and the 6th partition holding, in this way, reaching by the upgrading of the second mirror image to be upgraded
To the target for completing upgrade package upgrading.
In one embodiment, it is understood that there may be the mirror image to be upgraded that upgrade package includes target partition is updated to the backup point
Area, and the case where configuring power down when the state parameter of subregion is upgrading completion status, is set.To avoid by power down when terminal upgrade
And cause terminal that can not start, after terminal is restarted, if detecting, the state parameter of configuration subregion for upgrading completion status, can be incited somebody to action
The mirror image to be upgraded of target partition in backup subregion is written to target partition.For example, where target partition is file system
Six partition holdings when, if terminal detected after restarting configuration subregion state parameter for upgrading completion status, due to target
The mirror image to be upgraded of subregion has been written into backup subregion, at this point, only need to by corresponding to the target partition in backup subregion to
The 6th partition holding is written in upgrade image, and the state parameter that configuration subregion is arranged again later is removing state.In this way, when eventually
When end is restarted again, since file system has updated, and then it can avoid causing terminal that can not open due to power down in escalation process
Dynamic possibility.
Step 112, it controls the mirror image to be upgraded sequence that the upgrade package is included and upgrades the mirror image corresponded in partition holding.
In one embodiment, if target storage is the 6th partition holding where file system, if not wrapping in upgrade package
Containing mirror image to be upgraded corresponding to the 6th partition holding, at this point, the mirror image to be upgraded that can included according to control upgrade package is suitable
Sequence upgrades the mirror image in corresponding partition holding.
For example, in upgrade package include three Coutinuous stores mirror image to be upgraded, respectively positioned at first position first to
Upgrade image (corresponding first partition holding), positioned at the second mirror image (corresponding 4th partition holding) to be upgraded of the second position and position
In the third of the third place mirror image to be upgraded (corresponding second partition holding).At this point, execute updating operation when, at the first time,
It executes the first image upgrade to be upgraded is corresponding to the first partition holding；In the second time, execute the second mirror image liter to be upgraded
Grade is corresponding to the 4th partition holding；In the third time, execute third image upgrade to be upgraded is corresponding to the second partition holding.?
In other embodiments, it can not also be executed according to the sequence of the storage of mirrored storage to be upgraded, can such as randomly choose mirror to be upgraded
The updating operation of picture.
Above-mentioned firmware upgrade method can save the space of air upgrading: only need to reserve a backup Area-Specific Archive file system
System and a very small partitioned storage configuration parameter, the traditional full packet upgrading of relative contrast, can eliminate recovery mould
Formula, the boot and file system for saving recovery mode are taken up space, and storage upgrade package and progress power down protection

Grade when power down and cause terminal that can not start, after terminal is restarted, if processor 500 detect configuration subregion state parameter be
Download beginning state, it may be determined that power down occur when terminal downloads upgrade package, at this point, processor 500 can will be in backup subregion
The mirror image of file system is restored to target partition, to realize the reduction of system.For example, where target partition is file system
When six partition holdings, if terminal detects that the state parameter of configuration subregion for downloading beginning state, is deposited due to the 6th after restarting
The mirror image for storing up the file system of subregion has backed up in backup subregion, at this point, only need to be by the mirror of the file system in backup subregion
As the 6th partition holding of write-in, and then the state parameter of setting configuration subregion is removing state.In this way, working as terminal again
It is secondary when restarting, since file system has been restored, and then can avoid causing terminal that can not start due to power down in escalation process
Possibility.Processor 500 is also used to upgrade package from being distally downloaded in target partition, wherein upgrade package is from the target point
The first page in area starts to store.
After the completion of the downloading of upgrade package 40, processor 500 is also used to execute verification operation to upgrade package 40, when upgrade package 40
After verification operation passes through, processor 500 is also used to the state parameter of settable configuration subregion as downloading completion status.Processor
500 are also used to judge whether there is and store in the comparison check value and the header information 400 of at least one mirror image 402 to be upgraded
The reference check value of corresponding mirror image to be upgraded is not identical.When mirror image 402 to be upgraded each in upgrade package 40 comparison check value with
When the reference check value of the correspondence mirror image to be upgraded stored in the header information 400 is all the same, indicate that upgrade package downloading is complete
At at this point, processor 500 is also used to be arranged the state parameter of configuration subregion as downloading completion status.At least one wait rise if it exists
The reference check value of the corresponding mirror image to be upgraded stored in the comparison check value of class mirror-image 402 and the header information 400 not phase
Together, processor 500 is also used to controlling terminal and executes reboot operation.When terminal is restarted, due to the state parameter in configuration subregion
To download beginning state, at this point, loading time starting module can revert to the file system mirror of backup area in subregion, then just
After normally opened machine, the application program of operation downloading upgrade package is re-downloaded.
If the state parameter of the configuration subregion is downloading completion status, processor 500, which is also used to execute, is located at the mesh
The parsing operation for marking the upgrade package of subregion, obtains the mirror image to be upgraded that the upgrade package is included.
When the state parameter for configuring subregion is downloading completion status, the upgrade package 40 being stored in target storage is indicated
Verification operation is passed through, at this point, processor 500 can upgrade system according to upgrade package.Such as from first of target partition
The header information of upgrade package is read in page, then, is updated each mirror image to be upgraded of upgrade package to correspondence according to header information
Subregion where file system, can be completed image upgrade.
In one embodiment, the state parameter that configuration subregion is determined in restarting is downloading completion status, indicates that terminal exists
Power down when upgrade package is downloaded, i.e. processor 500 determine that upgrade package does not upgrade successfully, at this point, processor 500 can be again under
The head description for carrying packet is upgraded.
Processor 500 is also used to judge in the mirror image to be upgraded whether include the mirror image of the target partition, if so, locating
Reason device 500 is also used to the control when the mirror image to be upgraded for being included according to the upgrade package updates the mirror image in corresponding partition holding
It makes in the mirror image final updating to the target partition to be upgraded for corresponding to the target partition in the upgrade package；If it is not, processing
Device 500 is also used to control the mirror image sequential update to be upgraded that the upgrade package is included and corresponds to mirror image in partition holding.
