Embodiment
Below, with reference to accompanying drawing 1～2, describe method and the device of on-line upgrade of cross-platform version of the present invention in detail.
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: in new system, start guiding software (Bootloader) version and old key plate reserved fixed memory respectively in this in advance, reserved 11M fixed memory for example, store respectively new key plate this and old key plate originally in data to be preserved.
Wherein, the size basis of reserved fixed memory is waited to keep standing originally and the calculating of the size of data gets, owing to considering that redaction is big or small, can, in continuous variation, so reserved fixed memory size is relatively larger, there is so certain surplus to prevent that redaction from becoming large and reserving the inadequate situation of fixed memory.In addition, reserved fixed memory address is divided into 4 logic areas, deposits respectively key plate presents, start-up parameter data, user's configuration order data and business configuration order data.Each logical partition correspondence a data management structure, comprises length of zone name, partition size, partition data type, actual save data etc. is managed.In addition, reserved fixed memory has been carried out to ramdisk map operation.In version downloading process, version file is to be first saved in successively in internal memory, and this internal memory directly points to the version logical partition memory address of the high memory of advance reservation, and version file carries out after verification succeeds, and order can directly be returned.This just requires ramdisk to operate must be corresponding one by one to the data of its read-write and physical memory.The ramdisk of standard can not meet this condition, thus when being carried out to map operation, reserved fixed memory need to create a memory file equipment, and separately to its management, realize the function needing, 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 in this, and new Bootloader version; Or main control board obtains new key plate presents by communication between plate, FTP mode from neighbouring device, and downloads to reserved fixed memory.
Wherein, between main control board is by plate, communication is when neighbouring device obtains new key plate presents, and 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 completely automatically like this.Main control board, by starting a ftp client, obtains key plate presents to computer server or NM server, and downloads to reserved fixed memory.If version file to be obtained has miscellaneous editions file, can repeatedly obtain version file, according to filename or the version information that face records in front, distinguish corresponding memory address.
Step 300: after this new this verification succeeds of key plate, be saved in reserved fixed memory, and data adaptation to be preserved in old key plate basis is remained into reserved fixed memory.
Wherein, in step 300, due to the new version file the inside obtaining have version head, the inside preserve data length and version exclusive or check and, by these information, can carry out verification to the version file of downloading.If verification also remains into reserved fixed memory success, 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 ftp server, like this as long as main control board is told the filename that slave control board obtains, slave control board just can be by ftp from main control board access ramdisk equipment, and reserved fixed memory obtains corresponding version file.After slave control board verification completes, to main control board, reply verification and preserve success message.If version file obtains failure, or standby usage master control borad version file verification failure, order line is returned to failure and error reason.User determines whether to continue redaction to be loaded, if do not continue redaction, does not load, and does not also affect the former old key plate presents being saved in file system.
In addition, in step 300, the data that need to obtain comprise start-up parameter data, user's configuration order and business configuration order data, respectively by the subregion the inside that corresponding reserved fixed memory was obtained and preserved to module separately.Wherein, configuration order data due to early version and redaction command format incompatible, so need to make adaptation processing.Obtain data to be preserved in old key plate basis, it is adaptive and remain into reserved fixed memory, this operation is carried out can be saved in reserved fixed memory after this verification succeeds of key plate new to this after, such two orders can be merged into a command execution, user's operation is also simple, if operation failure, can return to miscue together.
Step 400: after the new Bootloader version verification succeeds of obtaining, its programming, to bootrom district, is then restarted to system.
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, after obtaining successfully, can directly be saved in system bootrom, does not need to remain into reserved fixed memory.
Particularly, the verification in internal memory of new Bootloader version file is arrived bootrom chip the inside by rear direct programming, backup to file system simultaneously, then main control board sends message to standby plate, slave control board starts ftp client, and main control board starts ftp server end, and the system of obtaining from main control board file system starts guiding software version file, after verification, directly programming is to the bootrom district of slave control board, and concurrent message upgrades successfully to master control borad.If standby usage master control borad has operation failure, with main control board order line, return, by user, determine it is again to upgrade or version rollback.
Step 500: new Bootloader version obtains new key plate presents in reserved fixed memory and the data of preservation in start-up course, resolves and be saved in flash or file system, and redaction loads and starts.
Wherein, in step 500, new Bootloader version, in start-up course, can not carry out the operations such as initialization to reserved patch internal memory, can directly obtain data, and new key plate presents is saved in file system, is saved in precalculated position after Data Analysis.
As shown in Figure 2, the device of on-line upgrade of cross-platform version of the present invention, comprising: reserved fixed memory module, software version acquisition module.
Wherein, reserved fixed memory module, for by reserved fixed memory is carried out to logical partition, different subregions are for depositing respectively originally significant data to be preserved of new various key plates this and old key plate.In addition, for other system (such as back-up system) can conveniently obtain the data in fixed memory by ftp mode, reserved fixed memory module, also for being mapped as the operation of file map to fixed memory.
Software version and data acquisition module, for the passage that obtains version file is provided, from PC server, NM server, or master control borad obtains version file to be upgraded, and obtains old key plate data to be preserved in this.Wherein, software version comprises that system key plate presents, firmware version file (such as nest plate initialization files) and system start guiding software Bootloader version file.In 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 in this, and new Bootloader version; Or main control board obtains new key plate presents by communication between plate, FTP mode from neighbouring device, and downloads to reserved fixed memory.In addition, in acquisition process, first version file to be downloaded in internal memory or in flash, then to its verification, if verification is no problem, just can preserve it afterwards.Consider that Installed System Memory is limited, software version and data acquisition module are by judgement and the analysis of certain condition, adopt internal memory and the shared mode of reserved fixed memory for preserving of buffer memory, can solve like this due to a reserved fixed memory, cause Installed System Memory that the large internal memory problem to version file buffer memory cannot be provided.If Installed System Memory is abundant certainly, also can not take this mode.
In addition, software version and data acquisition module, can be further used for the data of obtaining to be converted to the data of redaction identification, comprise data are compressed and processed or adaptation processing, can according to data function to be obtained, be divided into different submodules, each submodule obtains the data of corresponding function from system.
Software version and data memory module, for identifying whether the new version obtaining is the software version of current system compatibility, if the new version incompatible version that is current system, new key plate is originally saved in to reserved fixed memory, and data to be preserved in the old key plate basis of obtaining are saved in to reserved fixed memory subregion, by new Bootloader version, programming is to bootrom district, if version to be upgraded is the version file of current system compatible,, according to original storage mode, version file is directly saved in flash.
In addition, software version and data memory module, be further used for programming again to read out the file comparison with internal memory to the new Bootloader version file of bootrom, if unanimously just return and upgrade successfully; If upgraded unsuccessfully, as long as original Bootloader version file is obtained again, also programming is to bootrom, and system just return back to original version.
Version and Data Analysis are preserved module, and new key plate basis and data in the reserved fixed memory obtaining in start-up course for the Bootloader version to new are resolved and are saved in local flash or file system.Some system need to be firmware version file updates such as cpld to cpld the inside, and corresponding position is resolved and be saved in to the data in reserved fixed memory.
In sum, method and device according to on-line upgrade of cross-platform version of the present invention, by the mode of the reserved temporary transient save data of fixed memory and redaction, treat that new system is saved in flash reserved fixed memory version and data after starting guiding software startup again, system automatic acquisition adaptation data, thus the online upgrading of incompatible cross-platform version completed, reduced the cost of product, improve updating speed, reduced manual operation.
More than in order to make those of ordinary skills understand the present invention; and the detailed description that the present invention is carried out; but can expect; within not departing from the scope that claim of the present invention contains, can also make other changes and modifications, these variations and revising all in protection scope of the present invention.
