The high pass dual processor chip QSD7xxx and the QSD8xxx family chip that adopt with intelligent mobile terminal below illustrate following embodiment provided by the invention.This chip is dual processor (abbreviating double-core an as) chip, and (Baseband Processor, BP) (Application Processor, AP) dual processor constitutes with application processor by BBP.As shown in Figure 2, chip is made up of ARM9 (BP) and two processors of ARM11 (AP), and these two processors are realized through shared drive (Shared Memory) alternately.ARM9 is responsible for handling communication protocol, radio frequency, general I/O (GPIO) etc.ARM11 is responsible for common 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 the LINUX firmware, is loaded on the ANDROID firmware.ARM11 is called and is loaded by ARM9, and ARM9 is the main control chip on the ordinary meaning.Following map 2 is that the main firmware of chip is roughly introduced as follows with high pass QSD8:

PBL (Primary Boot Loader) is basic start-up loading device: be positioned at ARM9, be in plate carry read-only memory (Read-Only Memory, ROM) in, have the original code of starting terminal, be responsible for loading following DBL, generally need not to upgrade.

DBL (Device Boot Loader) is the device start loader: be positioned at ARM9; Employing is loaded into RAS (random access memory through reading flash memory flash with following OSBL, FSBL; RAM) mode in; Carry out the basic equipment configuration of terminal initialization, generally need not to upgrade.

FSBL (Fail-safe Boot Loader) promptly starts the recovery loader of makeing mistakes: be positioned at ARM9, be used for the recovery that makes mistakes to starting terminal, and load following OSBL, generally need not to upgrade.The processor chips of some manufacturer do not have independent FSBL, and its function is accomplished by DBL.

OSBL (Operating System Boot Loader) is the os starting loader: be positioned at ARM9, be used to load following A DSP, AMSS, APPSBL, and realize ARM9 processor end SD card upgrade, the checking verification with and the demonstration etc. of calling start logo.

APPSBL (Application system boot loader) application system start-up loading device: being positioned at ARM11, is the loader of ARM11 processor, is used for realizing ARM11 processor end SD card upgrade, and load operation system kernel (KERNEL) etc.In these processor chips, operating system nucleus is LINUX.

ADSP: being positioned at ARM9 end, is that (Digital Signal Processing DSP), receives the loading of above-mentioned OSBL during starting terminal for the digital signal processor of ARM9 end.

AMSS (Advanced Mobile Subscriber Software): being positioned at ARM9 end, is that (Operating System OS), receives the loading of above-mentioned OSBL during starting terminal for the operating system of processor A RM9.

LINUX (linux kernel): being positioned at the ARM11 end, is the operating system nucleus of processor A RM11, receives the loading of above-mentioned APPSBL during starting terminal.

The operating system of ANDROID (android system): ARM11 nuclear receives the loading of above-mentioned LINUX during starting terminal.

Each firmware is calling order shown in the arrow line among Fig. 2 in the starting terminal process, and OSBL on the BBP (BP) loads with it ADSP, the AMSS with nuclear, and the APPSBL of application processor (AP), realizes striding nuclear (processor) loading.

Fig. 2 also comprises the firmware update module of a Fota_ua by name; Be that (Firmware Over-the-Air, update agent FOTA) (update agent) are positioned on the LINUX of ARM11 end wireless firmware update; Be used for firmware is upgraded, when starting terminal, receive the loading of above-mentioned APPSBL.In the prior art, owing to the firmware update module is positioned on the LINUX itself, so can only realize renewal by LINUX to the ANDROID of its loading; And other firmwares that need upgrade, like AMSS, ADSP, and firmware such as LINUX itself; Cause is not that (LINUX also can't realize self upgrading by the LINUX loading; Can only realize its renewal by PC), so then can't upgrade it, promptly can't realize directly accomplishing the renewal of these firmwares through portable terminal through LINUX.

In one embodiment of the invention; The firmware update module is realized the renewal to other firmwares as a firmware separately; First firmware is that the firmware update module is Fota-ua (hereinafter to be referred as Fota); Operating system nucleus is LINUX, and the operating system firmware of its loading is ANDROID (relative operation system is the Android software systems).

Communication terminal knows that LINUX needs to upgrade, and then download LINUX and need upgrade needed Updating Information, and the predetermined flag position is set to a certain particular value, is used to represent that LINUX needs to upgrade.At the terminal once more in the start-up course; Be loaded on the Fota place, Fota reads the value of this predetermined flag position, knows that LINUX needs to upgrade; So confirm the above-mentioned writing position that Updates Information in LINUX, and above-mentioned Updating Information write this position and realize the renewal to LINUX.If write success, this predetermined flag position of Fota is set to another particular value, the renewal success of sign LINUX.

Above-mentioned communication terminal knows that LINUX needs to upgrade; Be when LINUX has had the renewal version; Obtain latest edition and notify all communication terminals (if the communication terminal of the mode of fixed connection is then notified through the fixed network circuit) to know by server end with the mode of radio broadcasting.Server end can with the latest edition of LINUX with and before version divide other mirror image or data, utilize pre-defined algorithm to make the mirror image of two versions or the difference bag of data, and preserve.

The version of latest edition before compared, and possibly be upgraded version, also maybe be therefore before the wrong and legacy version that need be reduced into of some of version, so above-mentioned renewal can be upgrading or reduction.And utilize the difference bag of two versions that pre-defined algorithm produces is incremental data, can be the data that directly increase or covers to the data of the former data of part position, and perhaps the both comprises.The above-mentioned different more new situation of using of pre-defined algorithm can be made mirror image difference bag such as algorithm and instrument that server end can use Redband to provide for any known incremental data algorithm or retrieving algorithm etc.

Server end also can not made the difference bag, but directly preserves the full content of redaction, directly downloads the total data of redaction for communication terminal, confirms the covering position on the LINUX, and the data of redaction are directly overlayed on the LINUX.But this mode makes the data volume of terminal downloads bigger, and the speed of renewal is also slower, especially to using the portable terminal and the less terminal of internal memory of wireless network, uses the writing mode of difference bag to have more advantage.

Above-mentioned communication terminal knows that LINUX needs to upgrade; Be through file system (the File System in the operating system firmware (being ANDROID); FS) unit detects server end has firmware (being LINUX in this example) to need to upgrade; So above-mentioned image difference bag (having mirror image difference bag with server end in this example is example) is downloaded in the FS unit, and deposits it in presumptive area of communication terminal in, in the particular zones of presumptive area such as nand (a kind of flash memory); Perhaps on the emmc card (a kind of embedded storer is usually used in portable terminal).Perhaps also can go up a software that moves and detect the difference bag whether server end has firmware update, detected the difference bag and notified the FS unit to download afterwards, or this software directly be downloaded to communication terminal by ANDROID.

FS writes the sign that LINUX need upgrade after having downloaded the unit mirror image difference bag of LINUX renewal needs in a status information file, restart the terminal then; This status information file can be the firmware update status indicator, is called zone bit FOTA_FLAG here, can be read by DBL, FSBL (when this firmware exists) and Fota and LINUX.The sign that LINUX need upgrade is above-mentioned second value, is assumed to be 2 (being merely for example, such as available binary number 0010 representative) here here.The initial value of zone bit FOTA_FLAG is assumed to be 1 (binary number 0001, promptly above-mentioned first value), and initial value representes that each firmware all need not to upgrade in the terminal.

In the process that the terminal starts once more, DBL reads the value of zone bit FOTA_FLAG, knows that the firmware that needs to upgrade is LINUX; So need not to handle especially; Configuration loads to basic equipment, keeps normal loading sequence, makes the terminal progressively be loaded on APPSBL.Above-mentioned DBL reads the value of zone bit FOTA_FLAG also can be undertaken by FSBL, and just because some chip products do not have independent FSBL, this place is only described with the value that DBL reads zone bit FOTA_FLAG.Owing to need not in the process that the terminal starts once more, to do special the processing, so DBL and FSBL are not the steps necessary that realization is upgraded LINUX by Fota to reading of zone bit FOTA_FLAG.After APPSBL loads Fota; Fota reads the value of zone bit FOTA_FLAG; Know that promptly LINUX needs to upgrade,, utilize the RedBend algorithm to write this position then and realize renewal LINUX so at first confirm the writing position of data in LINUX in the above-mentioned image difference bag.

After accomplishing above-mentioned writing; After promptly upgrading successfully; Fota writes complement mark in zone bit FOTA_FLAG, this complement mark can identify the renewal success (other values are successfully used in the renewal that is other firmwares) to LINUX specially, also can directly return to initial value 1 (above-mentioned first value); Because of having firmware, the initial value sign do not need to upgrade; And the renewal of LINUX has been accomplished, and (several firmwares needs news more simultaneously generally seldom occurs) when not having other firmwares need upgrade simultaneously, and also available initial value representes that LINUX has upgraded completion.Fota does not carry out the wireless renewal of firmware only, and Fota can use the update mode of describing among the application equally when wired renewal, realizes the renewal to firmware.

In a specific embodiment, communication terminal is downloaded Updating Information of above-mentioned second firmware update needs and comprised: communication terminal is verified second the Updating Information of firmware update needs, and will be deposited the precalculated position in through Updating Information of checking;

Updating Information of said second firmware update needs write the said write position to be comprised: obtain Updating Information of the second firmware update needs from said precalculated position, and Updating Information of second firmware update needs write the said write position.

FS unit on the ANDROID of terminal has been downloaded after the mirror image difference bag; Can directly deposit presumptive area in; Also can download back first buffer memory and verifying; Such as being that the information publisher discerns to server end, whether be information publisher's (is not by official's issue such as LINUX mirror image difference bag) of forged identity.After checking is passed through, again mirror image difference bag is write presumptive area.And in the follow-up step of updating, Fota will be through checking, and the difference bag that is kept at LINUX the renewals needs in this presumptive area reads and writes.

In another specific embodiment, the FS unit writes the particular zones of nand with the mirror image difference bag of LINUX, and after FOTA_FLAG is provided with the ident value that LINUX need upgrade; Directly guiding terminal gets into starting state once more, also can pass through display reminding message earlier, and whether inquiry restarts the terminal; If the user selects to skip the renewal link, then the value of the zone bit FOTA_FLAG sign LINUX zone bit that need upgrade is left 2, and the mirror image difference bag of LINUX renewals needs also is retained in the particular zones of nand; Continue to use the LINUX of current version in the terminal; When startup next time of terminal, when reading this zone bit, carry out the renewal of LINUX again by Fota.

In another embodiment, Fota oneself itself does not directly read the value of zone bit FOTA_FLAG.Meets above-mentioned FS and downloaded the difference bag that the LINUX renewal needs, and when communication terminal started once more, first firmware knew that the predetermined flag position is that second value comprises:

After knowing that by the 3rd firmware the predetermined flag position is set to second value, call said first firmware, make said first firmware know that said predetermined flag position is second value;

Wherein, said the 3rd firmware is in said communication terminal start-up course, directly to load the firmware of said first firmware.

The 3rd above-mentioned firmware is APPSBL, and it loads Fota in the starting terminal process.After APPSBL loads; The value that reads zone bit FOTA_FLAG is 2; Know that promptly LINUX needs to upgrade,, or directly notify LINUX to need renewal so the value of notification flag position FOTA_FLAG is 2 (tables of comparisons that in Fota, have value and its sign content of zone bit FOTA_FLAG) when loading Fota; Make Fota through confirming the writing position and write of Updating Information of LINUX, accomplish renewal LINUX what this position Updated Information.

In another embodiment, communication terminal comprises the processor that contains first nuclear and second nuclear, and first firmware is positioned at second nuclear, and operating system nucleus is positioned at second nuclear; And second firmware further comprises: the firmware that is positioned at first nuclear.

In this embodiment, second firmware also comprises ADSP and AMSS.It is ARM11 that the first firmware Fota and operating system nucleus LINUX are arranged in second nuclear, and to examine be ARM9 and ADSP and AMSS all are arranged in first.Fota not only can upgrade and its firmware LINUX with nuclear (promptly being positioned at same processor, hereinafter to be referred as examining together), can also stride nuclear and upgrade firmware ADSP and AMSS among the ARM9.Because carry out alternately through shared drive between the dinuclear; So the difference bag that ADSP that is downloaded by the FS unit of ANDROID or AMSS renewals need (is convenient description; Hereinafter is that example realizes firmware update to write differential data all) deposit the particular zones of nand in, be can be used for ADSP or AMSS that Xiang Yuqi is in different IPs by Fota to write and realize upgrading.The particular zones of nand in this example; With the particular zones of nand in the precedent can shared same particular zones; Which firmware the difference bag that the identification information of wrapping through difference is distinguished in the subregion belongs to; The difference bag that LINUX, ADSP and AMSS renewal are needed deposits the particular zones of different nand respectively in, can discern the difference bag that deposits in from the position of subregion and belong to which firmware.After Fota successfully writes the difference bag to the relevant position of ADSP or AMSS, feed back to OSBL, the ADSP or the AMSS that let OSBL call again after the renewal get into internal memory.

The value of zone bit FOTA_FLAG in the foregoing description is 2 only to identify LINUX and need to upgrade (promptly a concrete firmware needs renewal); The zone bit that ADSP and AMSS need upgrade can be set to other values (such as binary number 0011 and 0100), makes to know when Fota reads zone bit FOTA_FLAG that which concrete firmware needs to upgrade.In an alternative embodiment, the value of zone bit FOTA_FLAG is that 2 any or a plurality of firmwares that also can identify among LINUX, ADSP or the AMSS need to upgrade, because the update mode of these several kinds of firmwares is roughly the same, one type of firmware can playback.Carried the identification information of different firmwares in (difference bag) owing to Update Information; Fota is after reading zone bit FOTA_FLAG and knowing that which kind of firmware need upgrade; Can judge that which concrete firmware needs to upgrade according to these identification informations in Updating Information, make zone bit become simple like this; Such as only needing 8 scale-of-two is that the length that 1 Byte is provided with zone bit gets final product, and the follow-up embodiment of this paper all comes to describe for example in this way.The scene that two or three firmwares need upgrade simultaneously among LINUX, ADSP and the AMSS seldom; Even run into this kind scene; Know this type of firmware that all need upgrade in the identification information of Fota from the difference bag; Only after all these type of firmwares that need upgrade all successfully to upgrade, the value that Fota just can zone bit FOTA_FLAG is set to first value (like initial value 1).

In another embodiment, after above-mentioned second firmware update success, the first firmware predetermined flag position is set to first value and specifically comprises:

The first firmware predetermined flag position is set to first value.

In a specific embodiment, the firmware update data that the FS unit is downloaded from server end comprise the difference bag that LINUX, ADSP and/or AMSS upgrade needs, and the difference bag of ANDROID renewal needs.Certainly, the scene that ADSP and/or AMSS and ANDROID need upgrade simultaneously seldom, only under individual cases, LINUX and ANDROID need renewal simultaneously.Under the situation of having only a zone bit FOTA_FLAG, the value of zone bit FOTA_FLAG is set to 2, is used for indicating LINUX, ADSP and/or AMSS to need to upgrade, and this moment, Fota can't know whether ANDROID also needs to upgrade.In this embodiment, after LINUX, ADSP and/or AMSS upgraded successfully, Fota changed zone bit FOTA_FLAG into 3 by 2 earlier, notifies LINUX then, judged by LINUX whether ANDROID needs to upgrade.If ANDROID does not need to upgrade, then LINUX changes zone bit FOTA_FLAG into 1 (0001).1 is original state, promptly has no firmware to upgrade or all firmware update successes.If ANDROID needs to upgrade, then LINUX confirms that difference wraps in the writing position among the ANDROID, and the difference bag is write this position, accomplishes the renewal to ANDROID.

In the preferred embodiment on the foregoing description basis, after the predetermined flag position was set to the 3rd value, before the first firmware predetermined flag position was set to first value, this firmware update further comprised:

Know that through zone bit FOTA_FLAG which or which type firmware at terminal needs to upgrade, can upgrade under the situation of failure that in next start-up course, navigating to rapidly needs the firmware that upgrades and carry out the renewal of this firmware once more at this.

In above-mentioned these embodiment; When Fota upgrades LINUX, ADSP or AMSS; After Fota confirms that difference wraps in the writing position among LINUX, ADSP or the AMSS, difference is wrapped in this position write fashionable breaking down (comprising the terminal power down), cause the terminal to start once more; Because the value of zone bit FOTA_FLAG still is 2; In the start-up course, Fota knows that from the value of zone bit FOTA_FLAG this type of firmware of LINUX, ADSP or AMSS needs to upgrade once more at the terminal, in the writing position that then will Update Information at LINUX, ADSP or the AMSS that confirmed in the renewal process last time; Write accordingly once more and Update Information, realize renewal LINUX, ADSP or AMSS.After upgrading successfully, Fota returns the value setting of zone bit FOTA_FLAG to initial value.If this upgrades and still to run into fault, then in start-up course next time, continue above-mentioned renewal to LINUX, ADSP or AMSS.

Be set to after 3 at above-mentioned Fota zone bit FOTA_FLAG, if LINUX judges that ANDROID needs to upgrade, so ANDROID is upgraded.When LINUX breaks down to the renewal process of ANDROID, thus LINUX also not the value of zone bit FOTA_FLAG be set at 1 o'clock, the terminal starts because of upgrading fault once more, the value of zone bit FOTA_FLAG is left 3.In the process that starts once more, the value that Fota reads zone bit FOTA_FLAG is 3, knows that then ANDROID needs to upgrade, so directly notify LINUX that ANDROID is upgraded.After LINUX upgrades successfully to ANDROID; The value of zone bit FOTA_FLAG is set to 1; If LINUX fails to the renewal of ANDROID once more; Can continue still that above-mentioned terminal starts once more and value that Fota reads zone bit FOTA_FLAG is 3, and notice LINUX carries out updating steps to ANDROID.

Preamble is mentioned in describing; The firmware that communication terminal need upgrade also comprises OSBL, APPSBL and Fota self; When being directed to OSBL, APPSBL and Fota self and need upgrading, if only adopt method in the foregoing description to realize that terminal self upgrades these firmwares, in the process that Fota upgrades OSBL, APPSBL; If fault causes OSBL, APPSBL to damage; Back Fota could load because OSBL, APPSBL load successfully, so OSBL or APPSBL can't be recovered when starting once more in the terminal, then can't load Fota and continue uncompleted renewal last time.In addition, Fota also can't upgrade self.As shown in Figure 3, the embodiment of the invention adopts following mode to carry out firmware update:

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

Communication terminal predetermined flag position is set to the 4th value;

When communication terminal starts once more; After the 4th firmware knows that the predetermined flag position is the 3rd value; Form the backup firmware of the 5th firmware; First writing position in the backup firmware of the 5th firmware of Updating Information of confirming that the 5th firmware update needs, and Updating Information of needing of the 5th firmware update write first writing position, form the backup updating firmware of the 5th firmware;

The 4th firmware is confirmed second writing position in the 5th firmware, with the data in the backup updating firmware, writes second writing position, realizes the renewal of the 5th firmware;

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

Above-mentioned the 5th firmware comprises OSBL, APPSBL and Fota self; Certainly also can comprise ADSP, AMSS and LINUX; But the various embodiments that adopts preamble to mention to back three's renewal all can realize, so the following update method of only describing OSBL, APPSBL and Fota self.Difference bag and the broadcast announcement communication terminal of still making mirror image or data with server end below are that example is described.

In a specific embodiment; Communication terminal upward moves a detection software through FS unit or ANDROID knows that OSBL is that above-mentioned the 5th firmware needs upgrading (this example is example with the firmware upgrade); The difference bag that FS unit or detection software (hereinafter is an example with the FS unit) need the OSBL renewal is downloaded on the emmc card (also can be stored in the particular zones of nand) certainly; The value of predetermined flag position (being that example is described with zone bit FOTA_FLAG down) is set to 2 (here only for giving an example; Such as 2 being binary number 0010, sign OSBL needs to upgrade), promptly above-mentioned the 4th value.

When the terminal starts once more; Above-mentioned the 4th firmware is Fota through the value that reads zone bit FOTA_FLAG is 2 to know that the 5th firmware (OSBL) needs to upgrade; Satisfy the backup firmware of (in RAM) formation OSBL in the presumptive area at terminal; Confirm that then difference that OSBL renewals needs wraps in i.e. first writing position of writing position on the backup firmware of OSBL, and the difference bag of OSBL renewal needs is write first writing position, the backup firmware of OSBL is upgraded.Promptly generate the backup updating firmware of OSBL after upgrading successfully.

This moment, Fota confirmed earlier second writing position of OSBL, and the backup updating firmware of OSBL is write this second writing position.In general, writing of this second place, be covering to the OSBL prototype version, when covering successfully, also just realized the renewal of OSBL.After covering successfully, Fota reverts to 1 (initial value) with the value of zone bit FOTA_FLAG, does not promptly have firmware to need to upgrade.Because OSBL successfully upgrades,, " not having firmware to need to upgrade " upgrade successfully so also can be used to identify OSBL.

In another embodiment; Communication terminal knows that Fota itself needs to upgrade; The difference bag that the Fota renewal is needed in above-mentioned FS unit is downloaded on the emmc card, and zone bit FOTA_FLAG is set to 2, and 2 sign OSBL, APPSBL and this type of Fota firmware need to upgrade in this example; And specifically which firmware needs to upgrade, and then can from the identification information that difference is wrapped, know.After the terminal starts once more; Fota is known from zone bit FOTA_FLAG self to be needed to upgrade; Then (in RAM) forms the backup firmware of Fota in presumptive area, confirms that then difference that Fota renewals needs wraps in i.e. first writing position of writing position on the backup firmware of Fota, and with the Fota renewal need the difference bag write first writing position; Backup firmware to Fota is upgraded, and generates the backup updating firmware of Fota.Then, Fota confirms second writing position of self, makes the backup updating firmware of Fota write this second writing position.After writing successfully, Fota reverts to initial value 1 with the value of zone bit FOTA_FLAG.

In a preferred embodiment; Above-mentioned communication terminal is downloaded Updating Information of the 5th firmware update needs and is specially; Communication terminal is verified Updating Information of the 5th firmware update needs, and will be deposited the precalculated position in through the Updating Information of the 5th firmware update needs of checking;

FS unit on the communication terminal ANDROID has been downloaded after the mirror image or data difference subpackage of the 5th firmware; Can directly deposit presumptive area in; Also can download back first buffer memory and verifying; Such as being that the information publisher discerns to server end, whether be information publisher's (mirror image or data difference subpackage such as OSBL are not by official's issue) of forged identity.After checking is passed through, again above-mentioned image or data difference subpackage are write presumptive area.And in the follow-up step of updating, Fota will be through checking, and the difference bag that is kept at the 5th firmware (such as OSBL) the renewals needs in this presumptive area reads and writes.

In a specific embodiment, after zone bit FOTA_FLAG was provided with, the FS unit can get into starting state once more by guiding terminal; Also can pass through display reminding message earlier, whether inquiry restarts the terminal, if the user selects to skip the renewal link; Then the value of zone bit FOTA_FLAG is left 2, and mirror image or data difference subpackage that the OSBL renewal needs also are retained on the emmc card, when startup next time of terminal; The value that is read this zone bit by Fota is 2 o'clock, and row is upgraded to OSBL again.

In another embodiment, Updating Information that above-mentioned the 5th firmware update needs is the difference bag that the 5th firmware update needs;

In a specific embodiment; Updating Information is the mirror image difference bag (following abbreviation difference bag) of new and old two versions of the 5th firmware (such as APPSBL); After FS unit in the operating system deposited the difference bag presumptive area of terminal in, Fota i.e. the backup firmware of the formation APPSBL of the 4th firmware elder generation, utilizes pre-defined algorithm to confirm first writing position of firmware on the backup firmware of APPSBL that the APPSBL renewal needs; Come the difference bag is write, form the backup updating firmware of APPSBL.Pre-defined algorithm can be any known incremental data and corresponding incremental data retrieving algorithm, like algorithm and the instrument that uses Redband to provide.

Alternative with it embodiment also can be; The full content of APPSBL latest edition is directly downloaded at the terminal; When the backup firmware to APPSBL upgrades; Latest edition covered on the legacy version fully get final product, the writing position that promptly need not to use difference algorithm to confirm the difference bag with carry out difference and write.

In above-mentioned renewal process; The 5th firmware has experienced the link of backup-renewal-covering; And wherein arbitrary link is if fault; But service marking position FOTA_FLAG indicates the residing state of firmware update, so that can in start-up course next time, navigate to the link that the breaks down processing that continues rapidly.Promptly in upgrading (most for upgrading) process, accidents such as any failure or power down occur, Fota can both know in renewal process last time of terminal to stop at which kind of state according to FOTA_FLAG.

In another specific embodiment, the 4th firmware forms after the backup firmware of the 5th firmware, comprises the steps: that further the 4th firmware predetermined flag position is set to the 6th value;

Before the 5th firmware update success, this method further comprises:

Still need be updated to example with OSBL; After the 4th firmware Fota forms the backup firmware of the 5th firmware OSBL; Fota is that zone bit FOTA_FLAG is recorded as above-mentioned the 6th value with the predetermined flag position; Such as being 3 (in this example behind the down loading updating difference bag value of this zone bit still be set to 2), so carry out upgrading to the backup firmware of OSBL.If the upgrading of the backup firmware of OSBL is broken down and when restarting once more; Fota is 3 can know that the backup firmware of OSBL forms from the value of FOTA_FLAG zone bit; And (the backup updating firmware that is OSBL successfully generates) do not accomplished in the upgrading to the backup firmware of OSBL; So first writing position place that Fota can directly confirm in upgrading last time; The difference that carrying out the OSBL renewal needs wraps in writing on the backup firmware of OSBL, also can confirm first writing position again, carries out the renewal of the backup firmware of OSBL again.

On the basis of the foregoing description, perhaps in another independent embodiment, the 4th firmware forms after the backup updating firmware of the 5th firmware, and this method further comprises: the 4th firmware predetermined flag position is set to the 7th value;

Before the 5th firmware update success, this method further comprises:

When if communication terminal starts once more, the 4th firmware knows that the predetermined flag position is the 7th value, then returns the step of confirming second writing position in said the 5th firmware.

In one embodiment, if to the upgrading success of the backup firmware of OSBL, then the value of Fota zone bit FOTA_FLAG is set to the 7th value (such as being 4), proceeds the covering of the backup updating firmware of OSBL to former OSBL then.Value at FOTA_FLAG was set to before 4; Its value can be 3; The backup firmware of sign OSBL has formed and the also not generation of backup updating firmware of OSBL; Also can be 2, promptly only identifying OSBL need upgrade, and when the backup firmware of OSBL has formed, does not adjust the value of zone bit FOTA_FLAG.Under latter event, if cover failure, then the terminal in the start-up course, can't know that the backup firmware of OSBL forms once more, and Fota also need generate the backup firmware of OSBL once more.

On the basis of above-mentioned two embodiment, perhaps in another independent embodiment, the 4th firmware forms after the backup updating firmware of the 5th firmware, and this method further comprises: the 4th firmware predetermined flag position is set to the 7th value;

Before the 5th firmware update success, this method further comprises:

In a specific embodiment, if the backup updating firmware of OSBL is successful to the covering of OSBL, Fota is set to initial value 1 once more with the value (by 4, the foregoing description continues) of zone bit FOTA_FLAG, shows that the OSBL renewal finishes.If overwrite procedure breaks down, the value of zone bit FOTA_FLAG is left 4, when the terminal starts to Fota once more; The value that Fota reads FOTA_FLAG is 4; The backup updating firmware of knowing OSBL generates, and because fault has appearred in overwrite procedure, then Fota directly makes the backup updating firmware of OSBL cover second writing position on the OSBL; Perhaps confirm second writing position again, again OSBL is covered.

Because OSBL, APPSBL or the overwrite procedure of Fota backup updating firmware on former firmware break down; Can't normal load Fota in the time of possibly causing the terminal to start once more; So in the process that the terminal starts once more, the 6th firmware also can read (comprising DBL or FSBL) value of zone bit FOTA_FLAG.This example is example with DBL, when the value that reads zone bit FOTA_FLAG as DBL is 4, then can change the loading sequence of firmware.In this example; The value of zone bit FOTA_FLAG is that the 4 covering links that only identify in the renewal of OSBL, APPSBL or this type of Fota firmware go wrong; And do not indicate specifically in the renewal process of which firmware wherein that the backup updating firmware goes wrong to the covering of former firmware, be 4 o'clock so DBL reads the value of zone bit FOTA_FLAG; The identification information that also need combine the difference of firmware update needs to wrap to which concrete firmware is confirmed.

When being 4 such as value as zone bit FOTA_FLAG; That the overwrite procedure of backup updating firmware of judging DBL breaks down is OSBL; Then DBL changes the firmware loads order into FSBL-OSBL ' APPSBL by FSBL-OSBL-APPSBL, and OSBL ' is the backup updating firmware of OSBL.When being loaded on Fota, Fota knows that the value of zone bit FOTA_FLAG is 4, and the identification information of also wrapping through difference knows the fault that occurs in the renewal process of OSBL, and then second writing position of backup updating firmware on OSBL to OSBL covers.

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

Need to prove; DBL will read the value of zone bit FOTA_FLAG in each start-up course at terminal; When not needing it to change the firmware loads order; Be loaded on Fota in the normal order, read the value of zone bit FOTA_FLAG by Fota and judge the update mode that the terminal is present, continue corresponding the processing again; And when its change firmware loads order of needs, loading sequence is adjusted, thereby avoided occurring the above-mentioned situation that can't restart.

The above-mentioned situation that need not change the firmware loads order comprises: needs load in advance; When firmware that Fota could load (like OSBL, APPSBL) or Fota self need upgrade, the covering of backup updating firmware was broken down and is made the terminal need the situation that starts once more no thanks to; And early than, be later than or load simultaneously with Fota, but whether it successfully load the situation of the firmware (like ADSP, AMSS, LINUX and ANDROID) that can not have influence on the loading of Fota when needing to upgrade.

In a specific embodiment, this firmware update further comprises:

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

Communication terminal predetermined flag position is set to the 8th value;

After the 7th firmware update success, the 4th firmware predetermined flag position is set to first value;

Wherein, said the 7th firmware comprises: operating system nucleus.

Above-mentioned the 7th firmware comprises LINUX, and after communication terminal knew that through the FS unit LINUX need upgrade, the FS unit was rewritten as the 8th value (such as being 5) with zone bit FOTA_FLAG after downloading the difference bag, and guiding terminal starts once more.In the restarting process of terminal, after the value that Fota reads zone bit FOTA_FLAG is 5, need not to generate the backup firmware of LINUX, thus directly confirm the writing position that Updates Information of LINUX, and this writing position on LINUX, write above-mentioned difference bag.

In another embodiment, communication terminal comprises processor, and processor comprises the 3rd nuclear and the 4th nuclear, and the 4th firmware is positioned at the 4th nuclear, and operating system nucleus is positioned at the 4th nuclear, and the 7th firmware further comprises: the firmware that is positioned at the 3rd nuclear.

In a specific embodiment, the processor that adopt at the terminal is that double-core is BBP (BP) and application processor (AP), and the 3rd nuclear is BP, and the 4th nuclear is AP.Fota and LINUX are positioned on the AP, and the 7th firmware further comprises ADSP or the AMSS that is positioned on the BP.Carry out alternately through shared drive between the dinuclear; So the ADSP that is downloaded by the FS unit of ANDROID or the difference bag of AMSS renewals needs deposit presumptive area in, be to be used for ADSP or AMSS that Xiang Yuqi is in different IPs by Fota to write and realize upgrading.

On the basis of the foregoing description, after the 7th firmware update success, said the 4th firmware predetermined flag position is set to the 5th value and specifically comprises:

The said predetermined flag of the 4th firmware position is set to the 5th value.

After renewal success to the 7th firmware; Fota zone bit FOTA_FLAG is set to the 9th value (such as being 6); And notice LINUX judges whether and need upgrade ANDROID that do not need to upgrade if judged result is ANDROID, then LINUX zone bit FOTA_FLAG is set to i.e. 1 (binary number 0001) of the 5th value; Perhaps LINUX notifies Fota, and FOTA_FLAG is set to 1 by the Fota zone bit.Need to upgrade if judged result is ANDROID, then LINUX confirms that difference wraps in the writing position among the ANDROID, and the difference bag is write this position, realizes the renewal to ANDROID.Need to prove; If whole renewal process has only ANDROID to need to upgrade; FS begins soon, and zone bit FOTA_FLAG is set to 6; Fota obtains and can directly call LINUX after the value of zone bit FOTA_FLAG and come ANDROID is upgraded, so mostly above-mentioned update mode is that LINUX and ANDROID have issued redaction simultaneously thereby the occasion that need upgrade is simultaneously recommended.

Further; After the predetermined flag position is set to the 9th value; Before the 4th firmware predetermined flag position is set to the 5th value; This method further comprises: if when communication terminal starts once more, operating system nucleus knows that the predetermined flag position is the 9th value, then returns operating system is carried out updating steps.

Concrete; Upgrade failure (cutting off the power supply in such as renewal process) if LINUX breaks down to cause in the renewal process to ANDROID, then the value of zone bit FOTA_FLAG still remains 6 (the 9th values), in the start-up course next time at terminal; It is 6 that Fota identifies zone bit FOTA_FLAG; Then notify LINUX that ANDROID is upgraded, after ANDROID upgraded successfully, LINUX notified Fota; Fota zone bit FOTA_FLAG is set to the 5th value (being initial value 1), accomplishes whole renewal process.

In one embodiment; Before the 7th firmware update success; The 4th firmware confirms that the 7th firmware update needs Updates Information after the writing position in the 7th firmware; This method further comprises: Updating Information of the 7th firmware update needs write this writing position, realize the renewal of the 7th firmware.

If the 7th firmware (such as ADSP) breaks down in renewal process; Cause the terminal to start once more; When Fota is loaded; From the value of zone bit FOTA_FLAG is that the 8th value (5) identifies the 7th firmware and need upgrade, and the difference bag that then the ADSP renewal is needed writes the writing position of confirming in renewal process last time on ADSP, realizes the renewal to ADSP.

The present invention also provides a kind of chip, and is as shown in Figure 4, is applied in the communication terminal, and chip comprises first firmware and second firmware, and wherein, first firmware comprises:
