Description

Method and device for online upgrade of cross-platform versions

technical field

The invention relates to the field of communication technology, in particular to a method and device for online upgrading of cross-platform versions.

Background technique

Version upgrade is the most common operation in communication products. In order to meet new functions or new requirements, product versions need to be upgraded, and there may be cross-platform or cross-system version upgrades. For example, the original system uses the vxWorks operating system. In order to support some new functions, it needs to be replaced with a linux operating system; another example, due to the relationship between the platform, there may be inconsistencies between the data structure and module interface of the old and new versions. In order to upgrade the versions of these systems, the data compatibility of the versions before and after the upgrade must be considered first, and at the same time, the important data required by the system must not be lost; secondly, considering the cost of version upgrades, it is best to support remote batch online upgrades.

In the current version upgrade method, if the old system startup boot program can correctly guide the new main version, and the old and new file systems are compatible, then the version is directly stored in non-volatile storage media such as flash during the upgrade process , or the version is temporarily saved to memory first, and then saved to flash. If the data and module interfaces in the old version are not compatible in the new version, they will be used after compatibility processing in the new version. If the bootloader of the old system cannot boot the new main version, or if the old and new file systems are not compatible, you can only upload the data to be backed up to the network management server or computer in the old system, and then upgrade the new system to start Boot version, after the boot version starts, upgrade the main version file, the main version starts running, restore the pre-backed data in the main version, parse the data to meet the compatibility of the new version of the data interface and the module interface and save it .

However, the disadvantage of this method is that the new main version cannot be directly upgraded in the old version, and the main version must be upgraded in the new boot software, which is complicated to operate and cannot satisfy online upgrades; due to the incompatibility of the old and new file systems , the data cannot be saved, and needs to be backed up to other servers in advance, and the data can only be restored after the new main version runs. The operation is complicated and it is difficult to meet the batch online upgrade.

Detailed ways

Hereinafter, the cross-platform version online upgrade method and device of the present invention will be described in detail with reference to the accompanying drawings 1-2.

As shown in Figure 1, the method for cross-platform version online upgrade of the present invention comprises the following steps:

Step 100: Reserve fixed memory respectively in the new system boot software (Bootloader) version and the old main version in advance, for example reserve 11M fixed memory, respectively store the data to be saved in the new main version and the old main version .

Among them, the size of the reserved fixed memory is calculated according to the size of the version to be stored and the data. Considering that the size of the new version will continue to change, the size of the reserved fixed memory should be relatively large, so that there is a certain margin to prevent new versions When the size becomes larger and the fixed memory is not enough. In addition, the reserved fixed memory address is divided into 4 logical areas, which respectively store the main version file, startup parameter data, user configuration command data and service configuration command data. Each logical partition corresponds to a data management structure, including the management of the partition name, partition size, partition data type, and the length of the actual stored data. In addition, the ramdisk mapping operation is performed on the reserved fixed memory. During the version download process, the version files are first saved in the memory one by one. This memory directly points to the storage address of the version logical partition of the high-end memory reserved in advance. After the version file is verified successfully, the command can return directly. This requires that the ramdisk operation must have a one-to-one correspondence between the data it reads and writes and the physical memory. The standard ramdisk cannot meet this condition, so when performing mapping operations on reserved fixed memory, it is necessary to create a memory file device and manage it separately to achieve the required functions, which will not be described in detail here.

Step 200: Obtain the version file and data to be saved in the old main version; wherein, the version file includes the new main version, firmware version and Bootloader version.

Wherein, in step 200, the new main version, the data to be saved in the old main version, and the new Bootloader version can be obtained from the computer server or the network management server through USB or FTP; or the main main control board Obtain the new main version file from the adjacent device through inter-board communication and FTP, and download it to the reserved fixed memory.

Wherein, when the main main control board obtains a new main version file from an adjacent device through inter-board communication, the specific implementation process is as follows: the main main control board initiates an operation of obtaining a new main version through a command line or a network management system. The standby main control board initiates an operation according to the message initiated by the main control board, so that the version upgrade process of the standby main control board can be carried out automatically along with the upgrade of the active main control board. The main main control board obtains the main version file from the computer server or the network management server by starting an ftp client, and downloads it to the reserved fixed memory. If there are multiple versions of the version file to be obtained, the version file can be obtained multiple times, and the corresponding storage addresses are distinguished according to the information recorded in the file name or the version header.

Step 300: After the verification of the new main version is successful, save it to the reserved fixed memory, and adapt and save the data to be saved in the old main version to the reserved fixed memory.

Wherein, in step 300, since the acquired new version file contains a version header, which stores the data length and version XOR checksum, the downloaded version file can be verified through these information. If the verification and reservation are successful until the reserved fixed memory is successful, the active main control board sends a message to the standby main control board, and the active main control board waits for the standby main control board to reply. After receiving the message, the standby main control board will start an ftp client, and the active main control board will start the ftp server. In this way, as long as the active main control board tells the standby main control board the name of the file obtained, the standby main control board can use ftp from The main control board accesses the ramdisk device, that is, reserves fixed memory to obtain corresponding version files. After the verification of the standby main control board is completed, the main main control board shall reply with a verification and save success message. If the acquisition of the version file fails, or the version file verification of the active and standby main control boards fails, the command line returns the failure and the error reason. The user decides whether to continue loading the new version. If not, the old master version files originally saved in the file system will not be affected.

In addition, in step 300, the data to be obtained includes startup parameter data, user configuration commands and service configuration command data, which are respectively obtained and stored in corresponding partitions of reserved fixed memory through respective modules. Among them, the configuration command data needs to be adapted because the command formats of the old version and the new version are not compatible. Obtain the data to be saved in the old main version, adapt it and save it in the reserved fixed memory. This operation can be performed after the new main version is successfully verified and saved in the reserved fixed memory. Two commands can be combined into one command to execute, and the user operation is also simple. If the operation fails, an error message can be returned together.

Step 400: After successfully verifying the obtained new Bootloader version, burn it into the bootrom area, and then restart the system.

In step 400, the command to obtain the new Bootloader version file is initiated by the active main control board through a command line or network management, and the standby main control board sends a message to it through the main control board to initiate the operation. After the new Bootloader version is successfully obtained, it can be directly saved to the system bootrom, and does not need to be reserved for fixed memory.

Specifically, after the new Bootloader version file passes the verification in the memory, it is directly burned into the bootrom chip, and backed up to the file system at the same time, and then the active main control board sends a message to the standby main control board, and the standby main control board starts the ftp client. The main control board starts the ftp server, obtains the system startup boot software version file from the file system of the main control board, and after verification, directly writes it to the bootrom area of the standby main control board, and sends a message to the main control board that the upgrade is successful . If there is an operation failure on the main and standby main control boards, it will be returned together with the command line of the active main control board, and it is up to the user to decide whether to re-upgrade or roll back the version.

Step 500: During startup, the new Bootloader version acquires the new main version file and stored data in the reserved fixed memory, parses and saves them to flash or file system, and the new version is loaded and started.

Wherein, in step 500, during the startup process of the new Bootloader version, the reserved patch memory cannot be initialized and other operations can be directly obtained, and the new main version file is saved to the file system, and the data is parsed and saved to a predetermined location.

As shown in FIG. 2 , the cross-platform version online upgrade device of the present invention includes: a reserved fixed memory module and a software version acquisition module.

Wherein, the reserved fixed memory module is used for logically partitioning the reserved fixed memory, and different partitions are used to respectively store important data to be saved in various new main versions and old main versions. In addition, for other systems (such as standby systems) to conveniently obtain data in the fixed memory through ftp, a fixed memory module is reserved, and it is also used to map the fixed memory to a file image.

The software version and data acquisition module is used to provide a channel for obtaining version files, obtain the version files to be upgraded from the PC server, the network management server, or the main control board, and obtain the data to be saved in the old main version. Wherein, the software version includes a system main version file, a firmware version file (such as a chip initialization file) and a system startup boot software Bootloader version file. In the process of obtaining the version file, obtain the new main version, the data to be saved in the old main version, and the new Bootloader version from the computer server or the network management server through USB or FTP; Obtain the new main version file from the adjacent device through inter-board communication and FTP, and download it to the reserved fixed memory. In addition, in the acquisition process, the version file must first be downloaded into memory or flash, and then verified, and it will be saved only after the verification is correct. Considering that the system memory is limited, the software version and data acquisition module use the method of sharing the cached memory and the reserved fixed memory for storage through the judgment and analysis of certain conditions. Unable to provide large memory for version file cache. Of course, if the system memory is sufficient, this method may not be adopted.

In addition, the software version and data acquisition module can be further used to convert the acquired data into data recognized by the new version, including compressing or adapting the data, and can be divided into different sub-modules according to the function of the data to be acquired. Each sub-module obtains the data of the corresponding function from the system.

The software version and data storage module are used to identify whether the new version obtained is a software version compatible with the current system, and if the new version is a version incompatible with the current system, save the new main version to the reserved fixed memory, and Save the data to be saved in the obtained old main version to the reserved fixed memory partition, and burn the new Bootloader version to the bootrom area. If the version to be upgraded is a version file compatible with the current system, follow the original Storage method, the version file is directly saved to flash.

In addition, the software version and data storage module are further used to reread the new Bootloader version file programmed into the bootrom and compare it with the file in the internal memory. The file is reacquired and programmed into the bootrom, and the system returns to the original version.

The version and data parsing and saving module is used for parsing the new main version and data in the reserved fixed memory acquired by the new Bootloader version during startup and saving them in the local flash or file system. Some systems need to update the cpld and other firmware version files into the cpld, and analyze and save the data in the reserved fixed memory to the corresponding location.

To sum up, according to the cross-platform version online upgrade method and device of the present invention, the data and the new version are temporarily saved by reserving a fixed memory, and the reserved fixed memory version and the new version are saved after the new system boot software is started. The data is saved to flash, and the system automatically acquires and adapts the data, thus completing the online upgrade of incompatible cross-platform versions, reducing product costs, improving the upgrade speed, and reducing manual operations.

The above is a detailed description of the present invention for those skilled in the art to understand the present invention, but it is conceivable that other changes and modifications can be made without departing from the scope covered by the claims of the present invention. Variations and modifications are within the scope of the present invention.
