Description

发明名称：一种设备的远程升级方法、装置及*** 技术领域 Title of Invention: Method, Device and System for Remote Upgrade of Equipment

[0001] 本发明涉及动力环境监控领域，尤其涉及一种基于 NandFlash驱动设备的远程升级方法、装置及其***。 [0001] The present invention relates to the field of power environment monitoring, and in particular, to a remote upgrade method, device, and system thereof based on a NandFlash driving device.

背景技术 Background technique

[0002] 在动力环境监控应用中，基于 NandFlash驱动设备（例如 FSU (Field Supervision Unit, 区域智能监控单元））经过长吋间的运行后， NandFlash (非线性闪存，或快闪记忆体，或资料储存型闪存）存储介质会出现大量的坏块，以致设备的 N andFlash内存被占用完，没有多余的空间来存放有用的信息；同吋当 NandFlash出现大量坏块吋，会打印出大量的坏块信息，打印吋间超过一定吋间（例如 5秒），会导致看门狗复位，设备不停重启，却不能真正完全启动，导致启动不了，导致设备无法正常工作。 [0002] In a power environment monitoring application, NandFlash (non-linear flash memory, or flash memory, or data) after a long-running operation based on a NandFlash-driven device (such as a FSU (Field Supervision Unit)) Storage flash memory) A large number of bad blocks appear on the storage medium, so that the device's N and Flash memory is occupied, there is no extra space to store useful information. When NandFlash has a lot of bad blocks, it will print a lot of bad blocks. The information, when the printing time exceeds a certain time (for example, 5 seconds), will cause the watchdog to reset, the device will restart, but it will not be fully started, resulting in failure to start, resulting in the device not working properly.

[0003] 为了清除这些坏块，通常需要升级内核和 /或文件***来解决。目前，升级内核和 /或文件***的一般做法是需要维护人员下站到基站现场进行升级操作，例如，下站换设备板子，或者现场进行烧片。这种操作方案操作复杂，费吋，特别对于一些比较偏远的站点，下站维护成本高。 [0003] In order to clear these bad blocks, it is usually necessary to upgrade the kernel and / or file system to solve. Currently, the general practice of upgrading the kernel and/or file system is to require maintenance personnel to go to the base station for upgrade operations, for example, to change the equipment board at the next station, or to burn the film on site. This kind of operation scheme is complicated and expensive, especially for some relatively remote sites, and the maintenance cost of the lower station is high.

[0004] 鉴于此，有必要提供一种新的基于 NandFlash驱动设备的远程升级方法，以便可以让维护人员不用下站处理设备，通过在远端联网的环境下，实现远程在线升级，操作简单，节省人力，节约运行成本。 [0004] In view of this, it is necessary to provide a new remote upgrade method based on the NandFlash driving device, so that the maintenance personnel can implement the remote online upgrade in the remote networked environment without using the lower station processing device, and the operation is simple. Save manpower and save operating costs.

[0091] S221 : 将远程烧写工具 Nandwrite下载到基于 NandFlash驱动设备上，同吋也将内核（linux) 和文件*** （yaffs) 下载到设备中。 [0091] S221: Download the remote programming tool Nandwrite to the NandFlash-based device, and download the kernel (linux) and file system (yaffs) to the device.

[0092] S222:使用远程烧写工具 Nandwrite远程烧写内核（linux) 与文件*** （yaffs) 到 NandFlash驱动设备中，在烧写的同吋同步将校验信息也写入 NandFlash驱动设备中，这些校验信息，在 NandFlash驱动设备启动后会通过 u-boot来进行校验。 [0092] S222: remotely burning the kernel (linux) and the file system (yaffs) into the NandFlash driving device by using the remote programming tool Nandwrite, and simultaneously writing the verification information into the NandFlash driving device during the synchronization of the programming. The verification information is verified by u-boot after the NandFlash driver is started.

[0093] 具体地，校验方法如下：一般情况下，在远程烧写工具 Nandwrite中， OOB ( 参考图 2) 中的 ECC校验函数，与基于 NandFlash驱动设备***上的 u-boot的校验函数是不一致，通过远程烧写工具 Nandwrite写入后的内核 linux和文件*** yaffs ，在 u-boot校验吋不能获得通过， NandFlash驱动设备***无法正常启动。在本发明中，远程烧写工具 Nandwrite工具是经过修改优化，使得 u-boot，内核， nandwr ite的校验码一致，形成特定的远程烧写工具 Nandwrite, 这样就可以保证 NandFla sh驱动设备***可以正常启动。 [0093] Specifically, the verification method is as follows: In general, in the remote programming tool Nandwrite, the ECC check function in the OOB (refer to FIG. 2) and the verification based on the u-boot on the NandFlash-driven device system. The function is inconsistent. After the kernel linux and file system yaffs written by the remote programming tool Nandwrite, the u-boot checksum cannot be obtained, and the NandFlash drive device system cannot be started normally. In the present invention, the remote programming tool Nandwrite tool is modified and optimized, so that the verification codes of the u-boot, the kernel, and the nandwr ite are consistent, and a specific remote programming tool Nandwrite is formed, so that the NandFla sh driving device system can be ensured. Normal start.

[0094] 其中，远程烧写工具 Nandwrite是本发明所具有的特定功能，其主要功能是远程写入 NandFlash数据，以及使得 u-boot、内核、远程烧写工具的校验码一致。具体包括： [0094] The remote programming tool Nandwrite is a specific function of the present invention, and its main function is to remotely write NandFlash data, and make the verification codes of the u-boot, the kernel, and the remote programming tool consistent. Specifically, including:

[0099] S23: 获取现场运行配置信息，远程保存到 NandFlash的指定空间。 [0100] 获取现场运行配置信息，现场运行配置信息包括 IP信息、各种采集量、传感器的配置、以及驱动设备的相关配置信息。具体步骤： [0099] S23: Acquire the on-site running configuration information, and save it to the specified space of the NandFlash remotely. [0100] Obtaining on-site running configuration information, the on-site running configuration information includes IP information, various collection amounts, configuration of sensors, and related configuration information of the driving device. Specific steps:

[0101] 由于 NandFlash驱动设备在升级吋，会重新写入内核和 /或文件***后，内核与 NandFlash的映射表会发生改变，会导致原有数据文件丢失，包括现场运行配置信息也会丢失，在重新启动应用程序后，保存的文件信息会丢失，因此，在升级前，需要先保存好现场运行配置信息。 [0101] After the NandFlash driver device is upgraded, the kernel and/or the file system will be rewritten, and the mapping table between the kernel and the NandFlash will be changed, which may result in the loss of the original data file, including the field running configuration information. After restarting the application, the saved file information will be lost. Therefore, you need to save the live running configuration information before upgrading.

[0102] 本发明中，将包括 IP信息等现场运行配置信息数据保存在 NandFlash驱动设备的 u-boot分区中尚未被使用的空间中，也即：该指定空间是指 NandFlash驱动设备的 u-boot分区中尚未被使用的空间。在 NandFlash结构的驱动设备中，只有 u-boot的 f lash空间在升级过程中没有进行擦除与写入操作处理，所以，将包括现场 IP信息等现场运行配置信息数据保存在 u-boot尚未被使用的 NandFlash中，这样可以保证在升级过程中这些现场运行配置信息数据不会被擦除或覆盖。 [0102] In the present invention, the field running configuration information data including the IP information is stored in a space that has not been used in the u-boot partition of the NandFlash driving device, that is, the designated space refers to the u-boot of the NandFlash driving device. The space in the partition that has not been used yet. In the NandFlash structure of the drive device, only the u-boot's lash space is not erased and written during the upgrade process. Therefore, the live operation configuration information including the on-site IP information is saved in the u-boot. In the NandFlash used, this ensures that these field running configuration information data will not be erased or overwritten during the upgrade process.

[0103] 在 S21和 S22中，远程擦除工具 eraseko.so和远程烧写工具 Nandwrite可以采用以下的存储方式： [0103] In S21 and S22, the remote erase tool eraseko.so and the remote programming tool Nandwrite can use the following storage methods:

The solution is to use memory to store files and map the memory to a medium that can save files. Specifically, the tmpfs virtual file system is used. The file system uses memory as the storage medium of the file system, and all the upgrade files are placed in the virtual file system.
