High pass dual processor chip QSD7xxx and QSD8xxx family chip with intelligent mobile terminal employing illustrate following embodiment provided by the invention below.This chip is dual processor (referred to as double-core) chip, is made up of with application processor (ApplicationProcessor, AP) dual processor baseband processor (BasebandProcessor, BP).As in figure 2 it is shown, chip is made up of ARM9 (BP) and two processors of ARM11 (AP), the two processor is realized by shared drive (SharedMemory) alternately.ARM9 is responsible for processing communication protocol, radio frequency, universal input/output (GPIO) etc..ARM11 is responsible for usual task, and the operating system nucleus of operation is Linux, is loaded on the LINUX firmware of ARM11, and operating system Android is called by LINUX firmware, is loaded on ANDROID firmware.ARM11 is called by ARM9 and loads, ARM9 and the main control chip on ordinary meaning.Below against Fig. 2, the Main firmware of high pass QSD8 system chip is substantially described below:

PBL (PrimaryBootLoader) i.e. is basic start-up loading device: be positioned at ARM9, is in onboard read-only memory (Read-OnlyMemory, ROM), has the original code that terminal starts, and is responsible for loading following DBL, generally without updating.

DBL (DeviceBootLoader) i.e. equipment start-up loading device: be positioned at ARM9, adopt, by reading flash memory flash, following OSBL, FSBL are loaded into random access memory (randomaccessmemory, RAM) mode in, carry out the basic equipment configuration of terminal initialization, generally without updating.

FSBL (Fail-safeBootLoader) namely starts recovery loader of makeing mistakes: be positioned at ARM9, for the recovery made mistakes during terminal is started, and loads following OSBL, generally without updating.The processor chips of some manufacturer do not have independent FSBL, and its function is completed by DBL.

OSBL (OperatingSystemBootLoader) i.e. os starting loader: be positioned at ARM9, for loading following A DSP, AMSS, APPSBL, and realize ARM9 processor end SD card upgrade, checking verification and and call the display etc. of start logo.

APPSBL (Applicationsystembootloader) application system start-up loading device: be positioned at ARM11, it it is the loader of ARM11 processor, it is used for realizing ARM11 processor end SD card upgrade, and loads operating system nucleus (KERNEL) etc..In present processor chip, operating system nucleus is LINUX.

ADSP: be positioned at ARM9 end, is the digital signal processor (DigitalSignalProcessing, DSP) of ARM9 end, by the loading of above-mentioned OSBL when terminal starts.

AMSS (AdvancedMobileSubscriberSoftware): be positioned at ARM9 end, is the operating system (OperatingSystem, OS) of processor ARM9, by the loading of above-mentioned OSBL when terminal starts.

LINUX (linuxkernel): be positioned at ARM11 end, is the operating system nucleus of processor ARM11, by the loading of above-mentioned APPSBL when terminal starts.

ANDROID (androidsystem): the operating system of ARM11 core, by the loading of above-mentioned LINUX when terminal starts.

Shown in each firmware arrow line called sequentially in Fig. 2 in terminal start-up course, OSBL in baseband processor (BP) loads with it with ADSP, AMSS of core, and the APPSBL of application processor (AP), it is achieved load across core (processor).

Fig. 2 also comprises the firmware more new module of a Fota_ua by name, i.e. wireless firmware update (FirmwareOver-the-Air, FOTA) renewal agency (updateagent), it is positioned on the LINUX of ARM11 end, for firmware is updated, when terminal starts by the loading of above-mentioned APPSBL.In the prior art, owing to firmware more new module itself is positioned on LINUX, so the renewal of the ANDROID to its loading can only be realized by LINUX, and other need the firmware that updates, such as AMSS, ADSP, and the firmware such as LINUX itself, because not being loaded by LINUX, (LINUX also cannot realize self and update, can only be realized it by PC to update), so LINUX then cannot be passed through, it is updated, namely cannot realize completing either directly through mobile terminal the renewal of these firmwares.

In one embodiment of the invention, firmware more new module is realized the renewal to other firmwares separately as a firmware, first firmware and firmware more new module is Fota-ua (hereinafter referred to as Fota), operating system nucleus is LINUX, and the operating system firmware of its loading is ANDROID (corresponding operating system is Android software system).

Communication terminal knows that LINUX needs to update, then downloading LINUX needs to update required more new data, and predetermined flag position is set to a certain particular value, is used for representing that LINUX needs to update.It is again started up in process in terminal, being loaded into Fota place, Fota reads the value of this predetermined flag position, knows that LINUX needs to update, it is thus determined that the writing position that above-mentioned more new data is in LINUX, and above-mentioned more new data is write this position realize the renewal to LINUX.If writing successfully, this predetermined flag position is set to another particular value by Fota, and mark LINUX is updated successfully.

Above-mentioned communication terminal knows that LINUX needs to update, it is when LINUX has had more redaction, obtained latest edition by server end and in the way of radio broadcasting, notify all communication terminals (if the communication terminal of fixing connected mode, then notified by fixed network circuit) and know.Server end by the mirror image respectively of version before the latest edition of LINUX and its or data, can utilize pre-defined algorithm to make the mirror image of two versions or the difference bag of data, and preserve.

Latest edition relatively before version compare, it may be possible to upgraded version, it is also possible to needs, because of some mistake of version before, the legacy version being reduced into, so above-mentioned renewal can be upgrading or reduce.And utilize difference bag and the incremental data of two versions that pre-defined algorithm produces, it is possible to it is the data directly increased or covers the data to the former data position of part, or both comprise.The above-mentioned different update status of pre-defined algorithm used, it is possible to for any of incremental data algorithm or retrieving algorithm etc., such as server end can use the Redband algorithm provided and instrument to make mirror image difference bag.

Server end can not also make difference bag, but directly preserves the full content of redaction, directly downloads the total data of redaction for communication terminal, it is determined that the covering position on LINUX, the data of redaction is directly overlayed on LINUX.But the data volume that this mode makes terminal downloads is relatively big, the speed of renewal is also relatively slow, especially to using the mobile terminal of wireless network and the terminal that internal memory is less, uses the writing mode more advantage of difference bag.

Above-mentioned communication terminal knows that LINUX needs to update, it is the file system (FileSystem being operated by system firmware (i.e. ANDROID), FS) unit detects that server end has firmware (for LINUX in this example) to need to update, FS unit then downloads above-mentioned image difference bag (having mirror image difference bag for server end in this example), and it is deposited in the presumptive area of communication terminal, in the particular zones of presumptive area such as nand (a kind of flash memory), or on emmc card (a kind of embedded memory, be usually used in mobile terminal).Or can also be detected, by the software run on ANDROID, the difference bag whether server end has firmware to update, notify after difference bag having been detected that FS unit is downloaded, or this software directly downloads to communication terminal.

After FS unit has downloaded the LINUX mirror image difference bag updating needs, a status information file writes the LINUX mark needing to update, then restarts terminal；This status information file can update status indicator for firmware, is referred to herein as flag bit FOTA_FLAG, can be read by DBL, FSBL (when this firmware exists) and Fota and LINUX.LINUX needs the mark updated to be above-mentioned second value, it is assumed here that be 2 (being herein only for example, such as can represent with binary number 0010).The initial value of flag bit FOTA_FLAG is assumed to be 1 (binary number 0001, i.e. above-mentioned first value), and initial value represents that in terminal, each firmware is all without being updated.

In the process that terminal is again started up, DBL reads the value of flag bit FOTA_FLAG, knows that the firmware needing to update is LINUX, then without processing especially, basic equipment configuration is loaded, maintains normal loading sequence, make terminal progressively be loaded into APPSBL.Above-mentioned DBL reads the value of flag bit FOTA_FLAG also can be undertaken by FSBL, only because some chip products do not have independent FSBL, this place is only described with the DBL value reading flag bit FOTA_FLAG.Owing to the process without being again started up in terminal being made process especially, so the reading of flag bit FOTA_FLAG is not realized steps necessary LINUX being updated by Fota by DBL and FSBL.After APPSBL loads Fota, Fota reads the value of flag bit FOTA_FLAG, namely know that LINUX needs to update, then first confirm that the writing position in LINUX of the data in above-mentioned image difference bag, then utilize RedBend algorithm to write this position and realize the renewal to LINUX.

After completing above-mentioned write, namely after being updated successfully, Fota writes complement mark in flag bit FOTA_FLAG, this complement mark can identify being updated successfully of LINUX (i.e. other firmwares be updated successfully other values of use) specially, initial value 1 (above-mentioned first value) can also be directly returned to, because initial value mark does not have firmware to need to update, and the renewal of LINUX is complete, and there is no other firmwares simultaneously need to when updating (general seldom several firmwares occur simultaneously need to more news), also can represent that LINUX has been updated over initial value.Fota does not carry out the wireless renewal of firmware only, and when wired renewal, Fota can use update mode described in this application equally, it is achieved the renewal to firmware.

In a specific embodiment, the more new data packets that communication terminal is downloaded above-mentioned second firmware renewal and needed is drawn together: the more new data of the second firmware renewal needs is verified by communication terminal, and the more new data by verifying is stored in precalculated position；

The more new data write said write position that being updated by described second firmware needs includes: obtains the second firmware from described precalculated position and updates the more new data of needs, and the second firmware updates the more new data write said write position needed.

After FS unit on terminal ANDROID has downloaded mirror image difference bag, presumptive area can be directly stored in, first buffer memory being verified after can also downloading, such as server end and information publisher are identified, if be information publisher's (such as LINUX mirror image difference bag is not issued by official) of forged identity.After being verified, then mirror image difference bag is write presumptive area.And in follow-up renewal step, Fota by verifying, and will be saved in LINUX in this presumptive area and update the difference bag needed and read and write.

In another specific embodiment, the mirror image difference bag of LINUX is write the particular zones of nand by FS unit, and after FOTA_FLAG is arranged the LINUX ident value needing renewal, directly guiding terminal entrance can be again started up state, also display reminding message can be first passed through, ask whether to restart terminal, if user selects to skip renewal link, then flag bit FOTA_FLAG identifies LINUX needs the value of the flag bit updated to be left 2, LINUX updates the mirror image difference bag needed and is also retained in the particular zones of nand, the LINUX being continuing with in terminal current version, until when terminal starts next time, when being read this flag bit by Fota, carry out the renewal of LINUX again.

In another embodiment, Fota oneself itself does not directly read the value of flag bit FOTA_FLAG.Meet above-mentioned FS and downloaded the difference bag that LINUX renewal needs, and when being again started up by communication terminal, the first firmware knows that predetermined flag position is that the second value includes:

After being known that predetermined flag position is set to the second value by the 3rd firmware, calling described first firmware, described predetermined flag position is the second value to make described first firmware know；

Wherein, described 3rd firmware is, in described communication terminal start-up course, is loaded directly into the firmware of described first firmware.

The 3rd above-mentioned firmware is APPSBL, and Fota is loaded by it in terminal start-up course.After APPSBL loads, the value reading flag bit FOTA_FLAG is 2, namely know that LINUX needs to update, then loading the value of notification flag position FOTA_FLAG during Fota is 2 (value having flag bit FOTA_FLAG in Fota identifies the synopsis of content with it), or directly notice LINUX needs to update, make Fota be determined by the more new data writing position of LINUX and be updated the write of data in this position, complete the renewal to LINUX.

In another embodiment, communication terminal includes the processor containing the first core and the second core, and the first firmware is positioned at the second core, and operating system nucleus is positioned at the second core；And the second firmware farther includes: be positioned at the firmware of the first core.

In this embodiment, the second firmware also comprises ADSP and AMSS.First firmware Fota and operating system nucleus LINUX is arranged in the second core and ARM11, and ADSP and AMSS is respectively positioned in the first core and ARM9.Fota not only can update the firmware LINUX of core same with it (being namely positioned at same processor, hereinafter referred to as same core), moreover it is possible to updates firmware ADSP and the AMSS in ARM9 across core.Because being interacted by shared drive between dinuclear, so ADSP or AMSS downloaded by the FS unit of ANDROID updates the difference bag needed (for convenience of describing, hereafter all realize firmware and update writing differential data) it is stored in the particular zones of nand, it is can be realized updating for reading to ADSP or AMSS being in different IPs with it by Fota.The particular zones of nand in this example, same particular zones can be shared with the particular zones of nand in precedent, which firmware the difference bag that the identification information wrapped by difference is distinguished in subregion belongs to, LINUX, ADSP and AMSS can also be made to update the difference bag needed and to be stored in the particular zones of different nand respectively, namely can recognise that from the position of subregion which firmware the difference bag being stored in belongs to.After the relevant position of ADSP or AMSS is successfully written difference bag by Fota, feeding back to OSBL, ADSP or AMSS after allowing OSBL re invocation update enters internal memory.

The value of the flag bit FOTA_FLAG in above-described embodiment be 2 only mark LINUX need to update (i.e. a concrete firmware need renewal), ADSP and AMSS needs the flag bit updated to could be arranged to other values (such as binary number 0011 and 0100) so that Fota knows when reading flag bit FOTA_FLAG which concrete firmware needs to update.In an alternative embodiment, the value of flag bit FOTA_FLAG is that 2 any one or the multiple firmwares that also can identify in LINUX, ADSP or AMSS need to update, because the update mode of these several firmwares is roughly the same, can playback a class firmware.Owing to more new data (difference bag) carrying the identification information of different firmware, Fota is reading flag bit FOTA_FLAG knows it is after which kind of firmware needs renewal, can according to these identification informations in more new data, judge which concrete firmware needs to update, flag bit is so made to become simple, such as only needing 8 binary systems i.e. 1 Byte to arrange the length of flag bit, embodiment follow-up herein is illustrated description all in this way.Two or three firmwares in LINUX, ADSP and AMSS are simultaneously need to the scene updated is little, even if running into this kind of scene, Fota knows this type of firmware that be there is a need to update in the identification information from difference bag, only after this type of firmware that be there is a need to update all is successfully obtained renewal, the value of flag bit FOTA_FLAG just can be set to the first value (such as initial value 1) by Fota.

In another embodiment, after above-mentioned second firmware is updated successfully, predetermined flag position is set to the first value and specifically includes by the first firmware:

Predetermined flag position is set to the first value by the first firmware.

In a specific embodiment, FS unit updates, from the firmware more new data packets that server end is downloaded, the difference bag needed containing LINUX, ADSP and/or AMSS, and ANDROID updates the difference bag needed.Certainly, ADSP and/or AMSS and ANDROID is simultaneously need to the scene updated is little, and only on rare occasion, LINUX and ANDROID is simultaneously need to update.When only one of which flag bit FOTA_FLAG, the value of flag bit FOTA_FLAG is set to 2, and being used to refer to LINUX, ADSP and/or AMSS needs to update, and now Fota cannot know whether ANDROID is also required to update.In this embodiment, after LINUX, ADSP and/or AMSS are updated successfully, Fota is first changed flag bit FOTA_FLAG into 3 by 2, then notifies LINUX, LINUX judge that ANDROID is the need of renewal.If ANDROID need not update, then LINUX changes flag bit FOTA_FLAG into 1 (0001).1 is original state, does not namely have any firmware to need renewal or all firmwares to be updated successfully.If ANDROID needs to update, then LINUX determines that difference wraps in the writing position in ANDROID, and difference bag is write this position, completes the renewal to ANDROID.

In a preferred embodiment on above-described embodiment basis, after predetermined flag position is set to the 3rd value, before predetermined flag position is set to the first value by the first firmware, this firmware update farther includes:

Known that by flag bit FOTA_FLAG which or which the class firmware of terminal needs to update, when this updates unsuccessfully, in next time, start-up course can navigate to rapidly the firmware needing to update and again carry out the renewal of this firmware.

In these embodiments above-mentioned, at Fota to LINUX, when ADSP or AMSS is updated, Fota determines that difference wraps in LINUX, after writing position in ADSP or AMSS, difference is wrapped in when this position reads break down (including terminal power down), terminal is caused to be again started up, owing to the value of flag bit FOTA_FLAG is still 2, terminal is again started up in process, Fota knows LINUX from the value of flag bit FOTA_FLAG, this type of firmware of ADSP or AMSS needs to update, then by last time renewal process it has been determined that LINUX, in the writing position of ADSP or AMSS more new data, the corresponding more new data of write again, realize LINUX, the renewal of ADSP or AMSS.After being updated successfully, the value of flag bit FOTA_FLAG is arranged back initial value by Fota.If this renewal still runs into fault, then, in upper once start-up course, continue the above-mentioned renewal to LINUX, ADSP or AMSS.

After flag bit FOTA_FLAG is set to 3 by above-mentioned Fota, if LINUX judges, ANDROID needs to update, and then ANDROID is updated.When the renewal process of ANDROID is broken down by LINUX, so when the value of flag bit FOTA_FLAG is not also set to 1 by LINUX, terminal is again started up because updating fault, and the value of flag bit FOTA_FLAG is left 3.In the process being again started up, it is 3 that Fota reads the value of flag bit FOTA_FLAG, then know that ANDROID needs to update, and then directly ANDROID is updated by notice LINUX.After ANDROID is updated successfully by LINUX, the value of flag bit FOTA_FLAG is set to 1, if the renewal failure again that LINUX is to ANDROID, still may proceed to above-mentioned terminal be again started up and Fota to read the value of flag bit FOTA_FLAG be 3, and notify the LINUX step that ANDROID is updated.

Mention in described above, communication terminal needs the firmware updated also to include OSBL, APPSBL and Fota self, it is directed to OSBL, when APPSBL and Fota self needs to update, if realizing terminal self only with the method in above-described embodiment these firmwares are updated, at Fota to OSBL, in the process that APPSBL is updated, OSBL is caused if there is fault, APPSBL damages, due to OSBL, APPSBL loads Fota after successfully and could load, so OSBL or APPSBL cannot be recovered when terminal is again started up, then cannot load Fota to continue the renewal being not fully complete last time.It addition, self also be cannot be carried out updating by Fota.As it is shown on figure 3, the embodiment of the present invention carries out firmware renewal in the following way:

Communication terminal knows that the 5th firmware needs to update；

When communication terminal is again started up, 4th firmware knows that predetermined flag position is after the 3rd value, form the backup firmware of the 5th firmware, determine that the 5th firmware updates the more new data needed the first writing position in the backup firmware of the 5th firmware, and the more new data that the 5th firmware updates needs writes the first writing position, form the backup updating firmware of the 5th firmware；

The second writing position in the 5th firmware determined by 4th firmware, by the data in backup updating firmware, writes the second writing position, it is achieved the renewal of the 5th firmware；

Wherein, the 4th firmware is firmware more new module, and the 5th firmware is the 4th firmware, and/or in communication terminal start-up course, early than the 4th invoked firmware of firmware.

Above-mentioned 5th firmware includes OSBL, APPSBL and Fota self, certainly ADSP, AMSS and LINUX can also be comprised, but adopt previously mentioned various embodiments all can realize the renewal of rear three, so the update method of OSBL, APPSBL and Fota self is only described below.Still it is described for difference bag the broadcast announcement communication terminal of server end making mirror image or data below.

In a specific embodiment, by running an inspection software on FS unit or ANDROID, communication terminal knows that OSBL and above-mentioned 5th firmware need upgrading (this example for firmware upgrade), OSBL is updated the difference bag needed and is downloaded on emmc card (certainly also can be stored in the particular zones of nand) by FS unit or inspection software (hereafter for FS unit), the value of predetermined flag position (under be described for flag bit FOTA_FLAG) is set to 2 (herein only for citing, such as 2 i.e. binary number 0010, mark OSBL needs to update), i.e. above-mentioned 4th value.

When terminal is again started up, above-mentioned 4th firmware and Fota are 2 know that the 5th firmware (OSBL) needs to update by reading the value of flag bit FOTA_FLAG, then in the presumptive area of terminal, (such as in RAM), form the backup firmware of OSBL, it is then determined that OSBL updates the difference needed wraps in the writing position on the backup firmware of OSBL i.e. the first writing position, and the difference bag that OSBL updates needs writes the first writing position, the backup firmware of OSBL is upgraded.Namely the backup updating firmware of OSBL is generated after upgrading successfully.

Now Fota first determines second writing position of OSBL, and the backup updating firmware of OSBL is write this second writing position.In general, in the write of this second position, it is the covering to OSBL prototype version, is also achieved that the renewal of OSBL when covering successfully.Covering after successfully, the value of flag bit FOTA_FLAG is reverted to 1 (initial value) by Fota, does not namely have firmware to need to update.Because OSBL is successfully updated, so " not having firmware to need to update " also can be used to identify OSBL and be updated successfully.

In another embodiment, communication terminal knows that Fota itself needs to update, at above-mentioned FS unit, Fota is updated the difference bag needed and be downloaded on emmc card, and flag bit FOTA_FLAG is set to 2, in this example, 2 mark these class firmwares of OSBL, APPSBL and Fota need to update, and specifically which firmware needs to update, then can know from the identification information that difference is wrapped.After terminal is again started up, Fota is known from flag bit FOTA_FLAG self to be needed to update, in presumptive area, then (such as in RAM), form the backup firmware of Fota, it is then determined that Fota updates the difference needed wraps in the writing position on the backup firmware of Fota i.e. the first writing position, and the difference bag that Fota updates needs writes the first writing position, the backup firmware of Fota is upgraded, generates the backup updating firmware of Fota.Then, Fota determines the second writing position of self, makes the backup updating firmware of Fota write this second writing position.Writing after successfully, the value of flag bit FOTA_FLAG is reverted to initial value 1 by Fota.

In a preferred embodiment, the more new data that above-mentioned communication terminal is downloaded the 5th firmware renewal and needed is specially, 5th firmware is updated the more new data needed and is verified by communication terminal, and the more new data that the 5th firmware by verifying updates needs is stored in precalculated position；

After FS unit on communication terminal ANDROID has downloaded mirror image or the data difference subpackage of the 5th firmware, presumptive area can be directly stored in, first buffer memory being verified after can also downloading, such as server end and information publisher are identified, if be information publisher's (mirror image of such as OSBL or data difference subpackage are not issued by official) of forged identity.After being verified, then above-mentioned image or data difference subpackage are write presumptive area.And in follow-up renewal step, Fota will by verify, and be saved in this presumptive area the 5th firmware (such as OSBL) update need difference bag read and write.

In a specific embodiment, after flag bit FOTA_FLAG is configured, FS unit guiding terminal entrance can be again started up state, it is possible to first passes through display reminding message, asks whether to restart terminal, if user selects to skip renewal link, then the value of flag bit FOTA_FLAG is left mirror images that 2, OSBL renewals need or data difference subpackage is also retained on emmc card, until when terminal starts next time, by Fota read the value of this flag bit be 2 time, then OSBL upgrades by row.

In another embodiment, above-mentioned 5th firmware updates the more new data needed is that the 5th firmware updates the difference bag needed；

In a specific embodiment, more new data is the mirror image difference bag (following abbreviation difference bag) of the 5th new and old two versions of firmware (such as APPSBL), after difference bag is stored in the presumptive area of terminal by the FS unit in operating system, Fota i.e. the 4th firmware is initially formed the backup firmware of APPSBL, APPSBL updates the firmware needed the first writing position on the backup firmware of APPSBL to utilize pre-defined algorithm to determine, difference bag is read, forms the backup updating firmware of APPSBL.Pre-defined algorithm can be any of incremental data and corresponding incremental data retrieving algorithm, as used the Redband algorithm provided and instrument.

Alternative embodiment can also be with it, terminal directly downloads the full content of APPSBL latest edition, when the backup firmware of APPSBL is updated, latest edition is completely covered on legacy version, namely without using difference algorithm to determine the writing position of difference bag and to carry out difference write.

In above-mentioned renewal process, 5th firmware experienced by the link of backup-renewal-covering, and any of which link is if there is fault, flag bit FOTA_FLAG can be used to indicate that firmware updates state in which, in order to can navigate to rapidly, in upper once start-up course, the link broken down and carry out the process that continues.Namely occurring that any failure or power down etc. are unexpected in updating (most for upgrading) process, Fota can both according to FOTA_FLAG knows which kind of state that stops in terminal last renewal process.

In another specific embodiment, the 4th firmware farther includes following steps: predetermined flag position is set to the 6th value by the 4th firmware after forming the backup firmware of the 5th firmware；

Before the 5th firmware is updated successfully, the method farther includes:

Still need to be updated to example with OSBL, after the 4th firmware Fota forms the backup firmware of the 5th firmware OSBL, predetermined flag position and flag bit FOTA_FLAG are recorded as above-mentioned 6th value by Fota, it is such as 3 (in this example, after down loading updating difference bag, the value of this flag bit is still set to 2), in the upgrading being by the backup firmware to OSBL.If the upgrading of the backup firmware of OSBL is broken down and again restarts, Fota is 3 namely would know that the backup firmware of OSBL is formed from the value of FOTA_FLAG flag bit, and to the upgrading of the backup firmware of OSBL and be not fully complete (namely the backup updating firmware of OSBL is not successfully generated), so the first writing position place that Fota can directly determine in updating last time, carry out OSBL and update the write that the difference needed wraps on the backup firmware of OSBL, the first writing position can also be redefined, then carry out the renewal of the backup firmware of OSBL.

On the basis of above-described embodiment, or in another independent embodiment, after the 4th firmware forms the backup updating firmware of the 5th firmware, the method farther includes: predetermined flag position is set to the 7th value by the 4th firmware；

Before the 5th firmware is updated successfully, the method farther includes:

If communication terminal is again started up, the 4th firmware knows that predetermined flag position is the 7th value, then return the step of the second writing position determined in described 5th firmware.

In one embodiment, if upgrading successfully the backup firmware of OSBL, then the value of flag bit FOTA_FLAG is set to the 7th value (being such as 4) by Fota, then proceeds by the covering to former OSBL of the backup updating firmware of OSBL.Before the value of FOTA_FLAG is set to 4, its value can be 3, the backup firmware of mark OSBL has been formed and the backup updating firmware of OSBL does not also generate, can also be 2, namely only mark OSBL needs to be updated, and does not adjust the value of flag bit FOTA_FLAG when the backup firmware of OSBL is formed.In the case of the latter, if covering unsuccessfully, then terminal is again started up in process, will be unable to know that the backup firmware of OSBL is formed, and Fota also needs again to generate the backup firmware of OSBL.

On the basis of above-mentioned two embodiment, or in another independent embodiment, after the 4th firmware forms the backup updating firmware of the 5th firmware, the method farther includes: predetermined flag position is set to the 7th value by the 4th firmware；

Before the 5th firmware is updated successfully, the method farther includes:

In a specific embodiment, if the covering success that the backup updating firmware of OSBL is to OSBL, the value (by 4, continue above-described embodiment) of flag bit FOTA_FLAG is again set at initial value 1 by Fota, it was shown that OSBL updates complete.If overwrite procedure breaks down, the value of flag bit FOTA_FLAG is left 4, when terminal is again started up to Fota, it is 4 that Fota reads the value of FOTA_FLAG, know that the backup updating firmware of OSBL generates, and owing to overwrite procedure occurs in that fault, then Fota directly makes the backup updating firmware of OSBL cover the second writing position on OSBL, or redefine the second writing position, then OSBL is covered.

Owing to OSBL, APPSBL or Fota backup updating firmware overwrite procedure on former firmware breaks down, cannot normal load Fota when being likely to cause terminal to be again started up, so in the process that is again started up of terminal, the 6th firmware (including DBL or FSBL) also can read the value of flag bit FOTA_FLAG.This example, for DBL, when the value that DBL reads flag bit FOTA_FLAG is 4, then can change the loading sequence of firmware.In this example, the covering link that the value of flag bit FOTA_FLAG is in 4 renewals only identifying this class firmware of OSBL, APPSBL or Fota goes wrong, and specifically do not indicate in the renewal process of which firmware therein, the covering of former firmware is gone wrong by backup updating firmware, so DBL reads the value of flag bit FOTA_FLAG when being 4, also need to update, in conjunction with firmware, the identification information that the difference needed is wrapped, which concrete firmware is confirmed.

Such as when the value of flag bit FOTA_FLAG is 4, that the overwrite procedure of backup updating firmware of judging DBL breaks down is OSBL, then DBL is changed firmware loads order into FSBL-OSBL ' APPSBL, OSBL by FSBL-OSBL-APPSBL ' i.e. the backup updating firmware of OSBL.When being loaded into Fota, Fota knows that the value of flag bit FOTA_FLAG is 4, and the identification information wrapped also by difference knows the fault being occur in the renewal process of OSBL, then the backup updating firmware of OSBL the second writing position on OSBL is covered.

When DBL judge that the overwrite procedure of backup updating firmware breaks down be APPSBL time, FSBL-OSBL-APPSBL change loading sequence into FSBL-OSBL-APPSBL ', APPSBL ' i.e. the backup updating firmware of APPSBL.When DBL judge that the overwrite procedure of backup updating firmware breaks down be Fota time, OSBL-APPSBL-Fota change loading sequence into OSBL-APPSBL-Fota ', Fota ' i.e. the backup updating firmware of Fota.

It should be noted that, DBL will read the value of flag bit FOTA_FLAG in each start-up course of terminal, when not needing it and changing firmware loads order, it is loaded into Fota in the normal order, the value being read flag bit FOTA_FLAG by Fota judges the more new state that terminal is current, is further continued for corresponding process；And when at needs, it changes firmware loads order, loading sequence is adjusted, thus avoiding the occurrence of the above-mentioned situation that cannot restart.

The above-mentioned situation that need not change firmware loads order includes: needs load in advance, when firmware (such as OSBL, APPSBL) that Fota could load or Fota self need to update, break down not due to the covering of backup updating firmware and make terminal need the situation being again started up；And early than, be later than or load with Fota simultaneously, but its firmware (such as ADSP, AMSS, LINUX and ANDROID) whether successfully loading the loading not interfering with Fota needs situation when updating.

In a specific embodiment, this firmware update farther includes:

Communication terminal knows that the 7th firmware needs to update；

After 7th firmware is updated successfully, predetermined flag position is set to the first value by the 4th firmware；

Wherein, described 7th firmware includes: operating system nucleus.

Above-mentioned 7th firmware includes LINUX, after by FS unit, communication terminal knows that LINUX needs renewal, flag bit FOTA_FLAG is rewritten as after FS unit download difference bag the 8th value (being such as 5), and guiding terminal is again started up.In terminal restarting process, it is after 5 that Fota reads the value of flag bit FOTA_FLAG, it is not necessary to generate the backup firmware of LINUX, so directly determining the writing position of the more new data of LINUX, and this writing position on LINUX, write above-mentioned difference bag.

In another embodiment, communication terminal includes processor, and processor includes the 3rd core and the 4th core, and the 4th firmware is positioned at the 4th core, and operating system nucleus is positioned at the 4th core, and the 7th firmware farther includes: be positioned at the firmware of the 3rd core.

In a specific embodiment, the processor that terminal adopts is double-core and baseband processor (BP) and application processor (AP), and the 3rd core is BP, and the 4th core is AP.Fota and LINUX is positioned on AP, and the 7th firmware comprises ADSP or AMSS being positioned on BP further.Interacted by shared drive between dinuclear, so ADSP or AMSS downloaded by the FS unit of ANDROID updates the difference bag needed and be stored in presumptive area, it is can be realized updating for reading to ADSP or AMSS being in different IPs with it by Fota.

On the basis of above-described embodiment, after the 7th firmware is updated successfully, predetermined flag position is set to the 5th value and specifically includes by described 4th firmware:

Described predetermined flag position is set to the 5th value by the 4th firmware.

To after being updated successfully of the 7th firmware, flag bit FOTA_FLAG is set to the 9th value (being such as 6) by Fota, and notify that LINUX judges whether to need ANDROID is updated, if it is judged that need not update for ANDROID, then flag bit FOTA_FLAG is set to the 5th value that is 1 (binary number 0001) by LINUX, or LINUX notifies Fota, Fota flag bit FOTA_FLAG is set to 1.If it is judged that need to update for ANDROID, then LINUX determines that difference wraps in the writing position in ANDROID, and difference bag is write this position, it is achieved the renewal to ANDROID.It should be noted that, if whole renewal process only has ANDROID to need to update, FS starts to be set to 6 by flag bit FOTA_FLAG, Fota can directly invoke LINUX ANDROID is updated after obtaining the value of flag bit FOTA_FLAG, thus above-mentioned update mode mostly be LINUX and ANDROID issued redaction simultaneously thus simultaneously need to the occasion updated is recommended.

Further, after predetermined flag position is set to the 9th value, before predetermined flag position is set to the 5th value by the 4th firmware, the method farther includes: if communication terminal is again started up, operating system nucleus knows that predetermined flag position is the 9th value, then return the step that operating system is updated.

Concrete, if LINUX breaks down to cause in the renewal process to ANDROID updates unsuccessfully (power-off in such as renewal process), then the value of flag bit FOTA_FLAG is maintained as 6 (the 9th values), in the upper once start-up course of terminal, it is 6 that Fota identifies flag bit FOTA_FLAG, then ANDROID is updated by notice LINUX, after being updated successfully until ANDROID, LINUX notifies Fota, flag bit FOTA_FLAG is set to the 5th value (i.e. initial value 1) by Fota, completes whole renewal process.

In one embodiment, before the 7th firmware is updated successfully, after 4th firmware determines that the 7th firmware updates the more new data needed writing position in the 7th firmware, the method farther includes: the 7th firmware is updated the more new data needed and writes this writing position, it is achieved the renewal of the 7th firmware.

If the 7th firmware (such as ADSP) breaks down at no point in the update process, cause that terminal is again started up, to Fota be loaded time, from the value of flag bit FOTA_FLAG be the 8th value (5) identify the 7th firmware need be updated, then ADSP is updated the difference bag needed and writes the writing position on ADSP determined in renewal process last time, it is achieved the renewal to ADSP.

Present invention also offers a kind of chip, as shown in Figure 4, be applied in communication terminal, chip comprises the first firmware and the second firmware, and wherein, the first firmware comprises:
