Embodiment
Below, 1～2 method and the device of describing on-line upgrade of cross-platform version of the present invention in detail with reference to the accompanying drawings.
As shown in Figure 1, the method for on-line upgrade of cross-platform version of the present invention comprises the following steps:
Step 100: reserve fixed memory at new system start-up Bootstrap Software (Bootloader) version and old key plate respectively in this in advance, for example reserve the 11M fixed memory, store data to be preserved in new key plate this and the old key plate respectively.
Wherein, the size basis of reservation fixed memory is waited to keep standing originally and the calculating of the size of data gets, can so it is big relatively to reserve the fixed memory size, there be certain surplus to prevent that redaction from becoming big and reserving the not enough situation of fixed memory like this in continuous variation owing to consider the redaction size.In addition, be divided into 4 logic areas, deposit key plate presents, start-up parameter data, user's configuration order data and business configuration order data respectively reserving the fixed memory address.Each logical partition correspondence a data management structure, comprises zone name, partition size, partition data type, actual length of preserving data etc. are managed.In addition, carried out the ramdisk map operation to reserving fixed memory.In the version downloading process, version file is to be saved in successively in the internal memory earlier, and this internal memory directly points to the version logical partition memory address of the high memory of reserving in advance, and after version file carried out verification succeeds, order can directly be returned.This just requires ramdisk to operate must be corresponding one by one to the data and the physical memory of its read-write.The ramdisk of standard can not satisfy this condition, thus when carrying out map operation, fixed memory need create a memory file equipment to reserving, and, realize the function of needs separately to its management, be not described in detail in this.
Step 200: obtain version file and old key plate data to be preserved in this; Wherein, version file comprises new key plate basis, firmware version and Bootloader version.
Wherein, in step 200, can pass through USB or FTP mode, from computer server or NM server obtain new key plate this, old key plate data to be preserved this, and new Bootloader version; Perhaps main control board obtains new key plate presents by communication between plate, FTP mode from neighbouring device, and downloads to the reservation fixed memory.
Wherein, communication is when neighbouring device obtains new key plate presents between main control board is by plate, and the specific implementation process is as follows: main control board initiates to obtain new this operation of key plate by order line or webmaster.The message that slave control board is initiated according to master control borad is initiated operation, and the edition upgrading process of slave control board can be carried out with the upgrading of main control board fully automatically like this.Main control board obtains the key plate presents to computer server or NM server, and downloads to the reservation fixed memory by starting a ftp client.If version file to be obtained has multiple version file, then can repeatedly obtain version file, according to filename or version in front the information of face record distinguish corresponding memory address.
Step 300: after this new this verification succeeds of key plate, it is saved in the reservation fixed memory, and with the adaptive reservation fixed memory that remains into of data to be preserved in the old key plate basis.
Wherein, in step 300 since the new version file that obtains the inside have version head, the inside preserve data length and version exclusive or check and, can carry out verification to the version file of downloading by these information.If verification also remains into the success of reservation fixed memory, then main control board sends message to slave control board, and main control board wait slave control board is replied.Slave control board can start a ftp client after receiving message, main control board starts the ftp server, like this as long as main control board is told the filename that slave control board obtains, slave control board just can promptly be reserved fixed memory and be obtained corresponding version file by ftp from main control board visit ramdisk equipment.Reply verification to main control board after the slave control board verification is finished and preserve success message.If version file obtains failure, perhaps active and standby with master control borad version file verification failure, order line is returned failure and error reason.Whether user's decision continues redaction loads, and does not load if do not continue redaction, does not also influence the former old key plate presents that is saved in the file system.
In addition, in step 300, the data that need obtain comprise start-up parameter data, user's configuration order and business configuration order data, obtain and preserve the subregion the inside of corresponding reservation fixed memory respectively by module separately.Wherein, the configuration order data are because early version and redaction command format are incompatible, so need make adaptation processing.Obtain data to be preserved in the old key plate basis, it is adaptive and remain into the reservation fixed memory, this operation can be after key plate this verification succeeds new to this be saved in it to be carried out after reserving fixed memory, such two orders can be merged into a command execution, user's operation is also simple, if operation failure then can return miscue together.
Step 400: after the new Bootloader version verification succeeds of obtaining, its programming to the bootrom district, is restarted system then.
In step 400, the order of obtaining new Bootloader version file is that main control board passes through order line or webmaster is initiated operation, and slave control board is sent out message by master control borad to it and initiated operation.New Bootloader version can directly be saved among the bootrom of system after obtaining successfully, does not need to remain into the reservation fixed memory.
Particularly, the verification in internal memory of new Bootloader version file is arrived bootrom chip the inside by the direct programming in back, backup to file system simultaneously, main control board sends message to standby plate then, slave control board starts the ftp client, and main control board starts the ftp server end, obtains system start-up Bootstrap Software version file from the main control board file system, directly programming is to the bootrom district of slave control board after the verification, and concurrent message is upgraded successfully to master control borad.If active and standby have operation failure with master control borad, then return with the main control board order line, be to upgrade again or the version rollback by user's decision.
Step 500: new Bootloader version obtains the new key plate presents reserved in the fixed memory and the data of preservation in start-up course, resolve and be saved in flash or file system, and redaction loads also and starts.
Wherein, in step 500, new Bootloader version can not carry out operations such as initialization to reserving the patch internal memory in start-up course, can directly obtain data, and new key plate presents is saved in file system, is saved in the precalculated position after the data parsing.
As shown in Figure 2, the device of on-line upgrade of cross-platform version of the present invention comprises: reserve fixed memory module, software version acquisition module.
Wherein, reserve the fixed memory module, be used for by carrying out logical partition to reserving fixed memory, different subregions are used for depositing respectively new various key plates bases and old key plate significant data originally to be preserved.In addition,, reserve the fixed memory module, also be used for fixed memory is mapped as the operation of file map for other system (such as back-up system) can conveniently obtain data in the fixed memory by the ftp mode.
Software version and data acquisition module are used to provide the passage that obtains version file, and from PC server, NM server, perhaps master control borad obtains version file to be upgraded, and obtain data to be preserved in the old key plate basis.Wherein, software version comprises system's key plate presents, firmware version file (such as the nest plate initialization files) and system start-up Bootstrap Software Bootloader version file.In the version file acquisition process, by USB or FTP mode, from computer server or NM server obtain new key plate this, old key plate data to be preserved this, and new Bootloader version; Perhaps main control board obtains new key plate presents by communication between plate, FTP mode from neighbouring device, and downloads to the reservation fixed memory.In addition, in acquisition process, at first to download to version file in the internal memory or among the flash, then to its verification, if verification just can be preserved it after no problem.Consider that Installed System Memory is limited, software version and data acquisition module are by the judgement and the analysis of certain condition, adopt the internal memory of buffer memory and the shared mode of reservation fixed memory that is used to preserve, can solve like this owing to reserve a fixed memory, cause Installed System Memory that the big internal memory problem to the version file buffer memory can't be provided.If Installed System Memory is abundant certainly, also can not take this mode.
In addition, software version and data acquisition module, the data that can be further used for obtaining are converted to the redaction recognition data, comprise data are compressed processing or adaptation processing, can be divided into different submodules according to data function to be obtained, each submodule obtains the data of corresponding function from system.
Software version and data memory module, be used to discern whether the new version that obtains is the software version of current system compatible, if new version is the incompatible version of current system, then new key plate originally is saved in the reservation fixed memory, and the old key plate that will obtain in this data to be preserved be saved in the fixed memory subregion of reservation, with new Bootloader version, programming is to the bootrom district, if version to be upgraded is the version file of present system compatible, then according to original storage mode, version file directly is saved in flash.
In addition, software version and data memory module, be further used for programming to the new Bootloader version file of bootrom read out again with the file of internal memory relatively, if consistent just returning upgraded successfully; If the upgrading failure is arrived bootrom as long as original Bootloader version file is obtained also programming again, system just return back to original version.
Module is preserved in version and data parsing, is used for new key plate basis and the data of new Bootloader version in the reservation fixed memory that start-up course is obtained are resolved and are saved in local flash or the file system.Some system need be updated to the cpld the inside to firmware version files such as cpld, and corresponding position is resolved and be saved in to the data that will reserve in the fixed memory.
In sum, method and device according to on-line upgrade of cross-platform version of the present invention, temporarily preserve the mode of data and redaction by reserving fixed memory, treat that new system start-up Bootstrap Software is saved in flash reserving fixed memory version and data after starting again, system obtains and adaptation data automatically, thereby has finished the online upgrading of incompatible cross-platform version, has reduced the cost of product, improve updating speed, reduced manual operation.
More than be in order to make those of ordinary skills understand the present invention; and to detailed description that the present invention carried out; but can expect; in the scope that does not break away from claim of the present invention and contained, can also make other variation and modification, these variations and revising all in protection scope of the present invention.
