本发明涉及计算机技术领域，尤其涉及一种设备远程备份升级方法、装置、计算机存储介质及设备。The present invention relates to the field of computer technology, in particular to a device remote backup and upgrade method, device, computer storage medium and device.
背景技术Background technique
嵌入式设备从上电到应用程序正常运行，其间经历过一系列漫长的过程。嵌入式设备上电后，CPU开始运行，通常CPU会从某一个固定的物理地址开始运行，这个物理地址一般是Flash芯片的起始物理地址。Flash芯片的最初一段通常存放的是u-boot(UniversalBoot Loader，通用引导加载程序)，于是CPU就会开始运行u-boot的代码。完成Boot loader初始化后，根据代码中设定的内核区物理地址，Bootloader会把内核区压缩后的Linux镜像拷贝到内存中并解压。同时准备好内核的启动参数，如：console＝ttyS0,115200root＝31:2mtdparts＝ar7100-nor0，这里主要是把Bootloader里设置的MTD(memory technologydevice，存储技术设备)分区信息传递给内核，还有需要加载的根文件系统。最后跳转到内核入口开始运行。接下来Linux内核会挂载根文件系统，要挂载的根文件系统是通过内核启动参数来获取的。Embedded devices have gone through a series of long processes from power-on to normal operation of the application program. After the embedded device is powered on, the CPU starts to run. Usually, the CPU starts to run from a certain fixed physical address. This physical address is usually the starting physical address of the Flash chip. The first section of the Flash chip usually stores u-boot (Universal Boot Loader, universal boot loader), so the CPU will start to run the u-boot code. After completing the boot loader initialization, according to the physical address of the kernel area set in the code, the Bootloader will copy the compressed Linux image of the kernel area to the memory and decompress it. At the same time, prepare the startup parameters of the kernel, such as: console＝ttyS0, 115200root＝31:2mtdparts＝ar7100-nor0, here is mainly to pass the MTD (memory technology device, storage technology device) partition information set in the Bootloader to the kernel, there is also a need Mounted root filesystem. Finally jump to the kernel entry to start running. Next, the Linux kernel will mount the root file system, and the root file system to be mounted is obtained through the kernel startup parameters.
Linux内核继续初始化各种类型的驱动程序，完成之后会启动第一个应用程序，它的进程ID为1。这个应用程序可以由内核启动参数传入，如果没有则会默认执行/sbin/init。init进程会读取配置文件/etc/inittab，根据配置文件的内容它会完成两个工作，执行rcS和启动Shell。至此，Linux系统已经启动完成，给用户提供了一个Shell的交互环境，后续的行为就取决于用户的输入或者系统特定应用的加载。The Linux kernel continues to initialize various types of drivers, and after completion, it starts the first application, which has a process ID of 1. This application can be passed in by the kernel boot parameters, if not it will execute /sbin/init by default. The init process will read the configuration file /etc/inittab. According to the content of the configuration file, it will complete two tasks, execute rcS and start the Shell. So far, the Linux system has been started, and a Shell interactive environment is provided to the user, and the subsequent behavior depends on the user's input or the loading of a specific system application.
以上是嵌入式设备正常启动相关流程，但是现有嵌入式设备启动流程中进场会发现存在内核、文件系统升级成功但应用程序升级失败，或者内核与应用程序都升级成功但应用程序启动异常则运行另一目录的软件版本的问题，增加了由于内核已升级故与当前应用程序不兼容的情况。The above is the process related to the normal startup of embedded devices, but in the startup process of existing embedded devices, it will be found that the kernel and file system are successfully upgraded but the application upgrade fails, or both the kernel and the application are successfully upgraded but the application starts abnormally. Problems with running software versions from another directory, adding cases where the kernel has been upgraded and is not compatible with the current application.

本发明的目的在于提高一种嵌入式设备的远程备份升级方法，以解决外场发现的存在内核、文件系统升级成功但应用程序升级失败，或者内核与应用程序都升级成功但应用程序启动异常的问题，进一步解决由于内核已升级与当前应用程序不兼容的情况。The purpose of the present invention is to improve a remote backup and upgrade method for embedded devices to solve the problems found in the field that the kernel and file system upgrades are successful but the application program upgrades fail, or both the kernel and application programs are successfully upgraded but the application programs start abnormally. , to further solve the situation that the kernel has been upgraded and is not compatible with the current application.
图1为本发明一个实施例的设备远程备份升级方法的流程图。参照图1，本发明实施例的设备远程备份升级方法具体包括以下步骤：FIG. 1 is a flow chart of a method for remote backup and upgrade of equipment according to an embodiment of the present invention. Referring to Fig. 1, the device remote backup upgrade method of the embodiment of the present invention specifically includes the following steps:
S11、根据备份升级标志确定嵌入式设备待引导的目标系统文件是否为系统升级文件，所述嵌入式设备的flash存储空间中包括用于存储当前系统文件的第一存储区域、用于存储系统升级文件的第二存储区域以及备份升级标志管理区域。S11. Determine whether the target system file to be booted by the embedded device is a system upgrade file according to the backup upgrade flag, and the flash storage space of the embedded device includes a first storage area for storing the current system file for storage system upgrade A second storage area for files and a backup and upgrade sign management area.
其中，当前系统文件包括升级前的内核和根文件系统，系统升级文件包括升级的内核和根文件系统。在flash存储空间中内核kernel和根文件系统的存储方式如图2所示。参见图2，本发明对内核和根文件系统实现了双冗余备份。其中，第一存储区域包括两部分，一部分存储升级前的内核kernel1，一部分存储升级前的根文件系统rootfs1；第二存储区域也包括两部分，一部分存储升级的内核kernel2，一部分存储升级的根文件系统rootfs2。Wherein, the current system file includes the kernel and the root file system before the upgrade, and the system upgrade file includes the upgraded kernel and the root file system. The storage mode of the kernel kernel and the root file system in the flash storage space is shown in Figure 2. Referring to Fig. 2, the present invention realizes dual redundancy backup to the kernel and the root file system. Among them, the first storage area includes two parts, one part stores the kernel kernel1 before the upgrade, and the other part stores the root file system rootfs1 before the upgrade; the second storage area also includes two parts, one part stores the upgraded kernel kernel2, and the other part stores the upgraded root file System rootfs2.
本实施例中，在根据备份升级标志确定所述嵌入式设备待引导的目标系统文件是否为系统升级文件之前，远程获取升级包，即所述系统升级文件，判断所述系统升级文件是否为待更新的升级文件；若所述系统升级文件为待更新的升级文件，则将所述系统升级文件存储到所述第二存储区域，并修改所述备份升级标志，以将待引导的目标系统文件更新为所述系统升级文件。具体的，当应用层需要升级时，可根据获取的系统升级文件的版本号判别当前是否需要更新升级，若需要升级，则利用底层接口库进行升级包校验，并在校验成功后，更新对应备份升级标志区域。In this embodiment, before determining whether the target system file to be booted by the embedded device is a system upgrade file according to the backup upgrade flag, the upgrade package, that is, the system upgrade file, is obtained remotely, and it is judged whether the system upgrade file is a pending system upgrade file. An updated upgrade file; if the system upgrade file is an upgrade file to be updated, the system upgrade file is stored in the second storage area, and the backup upgrade flag is modified so that the target system file to be booted Update the system upgrade file as described. Specifically, when the application layer needs to be upgraded, it can be judged according to the version number of the obtained system upgrade file whether it needs to be updated and upgraded. Corresponds to the backup upgrade flag area.
S12、若目标系统文件为系统升级文件，则从所述第二存储区域中获取所述系统升级文件，并对所述系统升级文件进行数据校验。S12. If the target system file is a system upgrade file, acquire the system upgrade file from the second storage area, and perform data verification on the system upgrade file.
S13、若所述系统升级文件校验失败，则修改所述备份升级标志，以标识嵌入式设备备份升级失败，以及将待引导的目标系统文件切换为当前系统文件。S13. If the verification of the system upgrade file fails, modify the backup upgrade flag to indicate that the backup upgrade of the embedded device fails, and switch the target system file to be booted to the current system file.
本发明实施例中，在所述系统升级文件校验失败之后，还包括：当备份升级标志标识嵌入式设备备份升级失败时，根据备份升级标志确定嵌入式设备当前待引导的目标系统文件为当前系统文件，此时获取所述当前系统文件，并对所述当前系统文件进行数据校验。若所述当前系统文件校验成功，则根据所述当前系统文件进行系统启动。若所述当前系统文件校验失败，则再次将待引导的目标系统文件切换为系统升级文件。具体的，系统文件，即内核或根文件系统，切换次数try不大于切换阈值，由于本实施例中，内核和根文件系统只实现双冗余备份，3次就能遍历完Flash中能使用的映像，所以切换阈值可设置为3次，当大于3次则，进入控制台。In the embodiment of the present invention, after the verification of the system upgrade file fails, it further includes: when the backup upgrade flag indicates that the backup upgrade of the embedded device fails, according to the backup upgrade flag, it is determined that the target system file to be booted by the embedded device is the current System files, at this time, the current system files are obtained, and data verification is performed on the current system files. If the verification of the current system file is successful, the system is started according to the current system file. If the verification of the current system file fails, the target system file to be booted is switched to a system upgrade file again. Concretely, system file, i.e. kernel or root file system, switching times try is not greater than switching threshold value, because in this embodiment, kernel and root file system only realize double redundant backup, just can walk through all available in Flash 3 times image, so the switching threshold can be set to 3 times, and when it is greater than 3 times, it will enter the console.
本发明实施例中，嵌入式设备的flash存储空间中包括了内核kernel及其备份区域、根文件系统及其备份区域以及额外增加的备份升级标志区域管理区。系统远程升级需要u-boot的支持，u-boot引导内核和根文件系统是通过bootm命令来完成的，所以本发明通过改变bootm的处理流程实现。In the embodiment of the present invention, the flash storage space of the embedded device includes the kernel kernel and its backup area, the root file system and its backup area, and an additional backup upgrade flag area management area. The remote upgrade of the system requires the support of u-boot, and the u-boot guides the kernel and the root file system through the bootm command, so the present invention is realized by changing the processing flow of the bootm.
在实际应用中，完成Bootloader初始化后，根据代码中设定的内核区物理地址，Bootloader会把内核区压缩后的Linux镜像拷贝到内存中并解压。同时准备好内核的启动参数，如：console＝ttyS0,115200root＝31:2mtdparts＝ar7100-nor0，这里主要是把Bootloader里设置的MTD分区信息传递给内核，然后加载根文件系统。因此，内核和根文件系统分别对应自己的备份升级标志，参见图3。在flash存储空间中备份升级标志管理区域的存储方式如图3所示，备份升级标志包括current、pending、update三个标志位，初始时刻三个标志位均为0。In practical applications, after bootloader initialization is completed, according to the physical address of the kernel area set in the code, the Bootloader will copy the compressed Linux image of the kernel area to the memory and decompress it. At the same time, prepare the startup parameters of the kernel, such as: console=ttyS0,115200root=31:2mtdparts=ar7100-nor0, here mainly transfer the MTD partition information set in the Bootloader to the kernel, and then load the root file system. Therefore, the kernel and the root file system respectively correspond to their own backup and upgrade marks, as shown in Figure 3. The storage mode of the backup upgrade flag management area in the flash storage space is shown in Figure 3. The backup upgrade flag includes three flag bits current, pending, and update, and the three flag bits are all 0 at the initial moment.
当远程获取到系统升级文件，将pending指向待引导的目标系统文件，即pending取值1，标识待引导的目标系统文件为第二存储区域的系统升级文件，update取值0xff，表示需要重新启动进行升级。When the system upgrade file is obtained remotely, point pending to the target system file to be booted, that is, the value of pending is 1, indicating that the target system file to be booted is the system upgrade file in the second storage area, and the value of update is 0xff, indicating that a restart is required to upgrade.
该方法在uboot启动时，执行bootm，bootm根据备份升级标志区域current、pending与update来确定拟引导的内核与根文件系统，当current、pending、update三个标志位取值为0、1、0xff时，表示需要重新启动进行升级，从第二存储区域中获取系统升级文件，然后对其进行CRC校验，校验成功则继续，否则切换到另一个映像，重新执行bootm流程。解压后，u-boot交出控制权。This method executes bootm when uboot starts, and bootm determines the kernel and root file system to be booted according to the backup and upgrade flag areas current, pending, and update. When the three flags of current, pending, and update take values of 0, 1, and 0xff , it means that it needs to be restarted to upgrade, obtain the system upgrade file from the second storage area, and then perform CRC verification on it, and continue if the verification is successful, otherwise switch to another image and execute the bootm process again. After decompression, u-boot surrenders control.
如果根据系统升级文件系统能正常启动，则会对备份升级标志作进一步处理，即current＝pending，update＝0xff，此时表示嵌入式设备备份升级成功。否则，将update取值设置为0，即current、pending、update三个标志位此时为0、1、0，系统自动重启。这时候，u-boot读取update，update没被设置为0xff,u-boot判定为上一次系统没启动升级成功，然后系统会切换映像，即切换到第一存储区域的当前系统文件，此时，current＝pending，pending＝(pending+1)％2。If the file system can be started normally according to the system upgrade, the backup upgrade flag will be further processed, namely current=pending, update=0xff, which means that the backup upgrade of the embedded device is successful. Otherwise, set the value of update to 0, that is, the three flags of current, pending, and update are 0, 1, and 0 at this time, and the system will automatically restart. At this time, u-boot reads update, and update is not set to 0xff, and u-boot judges that the last system failed to start and upgrade successfully, and then the system will switch the image, that is, switch to the current system file in the first storage area, at this time , current=pending, pending=(pending+1)%2.
