[0058] Through the above-mentioned drawings, specific embodiments of the present disclosure have been shown, and more detailed descriptions will be provided later. These drawings and textual descriptions are not intended to limit the scope of the concept of the present disclosure in any way, but to illustrate the concept of the present disclosure to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0059] Here, exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure.

[0060] Currently, during the use of embedded devices, in order to better cope with more application scenarios, updates are required.

[0061] In one example, the online upgrade method of the embedded device mainly involves downloading and updating the complete firmware package. However, in the prior art, when downloading and updating the complete firmware package, since the firmware package for updating is too large, the download process takes a long time. Moreover, during the wireless transmission process, problems such as network instability may cause the upgrade to fail, affecting the usage effect, resulting in low data transmission efficiency, and further leading to low update efficiency.

[0062] In one example, the online upgrade method of the embedded device includes partition upgrade of the firmware package, that is, partitioning the firmware package program and upgrading according to the changed partition. However, partition upgrade is mainly for large systems, and it is necessary to configure the FLASH address range for each module code during the program development process, which has many restrictions, is cumbersome, and the reserved amount is not easy to control.

[0063] An update processing method, device, embedded device, and system for an embedded device provided in this application aim to solve the above technical problems in the prior art.

[0064] The following uses specific embodiments to elaborate in detail on the technical solution of this application and how the technical solution of this application solves the above technical problems. These several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0065] Figure 1 The following is a schematic flowchart of an update processing method for an embedded device provided in an embodiment of this application, which is applied to an embedded device. The embedded device is deployed with an application program, such as Figure 1 As shown, the method includes:

[0066] Step 101: If a new firmware package sent by the code management system is received, store the new firmware package in the storage module; where the new firmware package is generated by the code management system when it determines that the current running version of the application program is different from the target update version; the target update version is determined according to the obtained version information of the application program.

[0067] Exemplarily, the execution subject of this embodiment can be an embedded device. First, Figure 2 The following is a schematic flowchart of another update processing method for an embedded device provided in an embodiment of this application, such as Figure 2As shown in the figure, the embedded device includes a single-chip microcomputer, instruments such as a flowmeter, sensors for collecting data, etc. An application program APP 22, a storage module 24, and a BootLoader 23 are deployed on the single-chip microcomputer. The update process of the embedded device is realized through wired / wireless interaction between the embedded device and the code management system 21. The code management system 21 is used to manage the firmware codes of various versions of various types of embedded devices, and the code management system 21 includes the firmware codes of various versions of the embedded device imported in advance.

[0068] In this step, during the interaction between the code management system and the embedded device, the code management system obtains the version information of the application program. The version information includes the software version information and the hardware version information of the currently running version. According to the mapping relationship between the preset hardware version information and the update version, the code management system determines and recommends the most suitable target update version corresponding to the hardware version information, and judges whether the currently running version is the target update version. If it is not the target update version, the code management system compares the software version information with the target version information of the target update version to generate a new firmware package, and finally sends the new firmware package to the embedded device. When the embedded device receives the new firmware package sent by the code management system, it stores the new firmware package in the storage module of the application program.

[0069] Specifically, during the process of the code management system generating a new firmware package, the code management system compares the target version information of the target update version with the software version information of the currently running version to obtain the same code content and different code content obtained by the comparison. It copies the address information and length information of the same code content obtained by the comparison to the new firmware package, and writes the different code content obtained by the comparison into the new firmware package, thereby obtaining a complete new firmware package. The new firmware package includes a start symbol, the number of frames, frame data, and a firmware CRC check code.

[0070] Step 102: Switch the current operating mode to the Bootloader mode.

[0071] Exemplarily, the embedded device switches the current operating mode to the Bootloader mode.

[0072] Step 103: In the Bootloader mode, update the currently running version of the application program according to the new firmware package to obtain the updated application program.

[0073] Exemplarily, in the Bootloader mode, first, the embedded device determines whether there is a new firmware package in the storage module according to the start symbol in the new firmware package. If it is determined that there is a new firmware package in the storage module, for the same code content, according to the address information and length information of the same code content in the new firmware package, the backup address corresponding to the address information in the pre-backup backup program is determined, and the firmware code at the backup address is copied to the application program. For different code content, the different code content in the new firmware package is decompressed, and the decompressed content is updated to the application program to obtain the updated application program.

[0074] For example, Figure 3 is a data structure diagram of an update processing method for an embedded device provided by an embodiment of the present application, as Figure 3 shown Figure 3 is the firmware compressed file structure in the new firmware package, including: start symbol, number of frames, frame data, firmware CRC check code, where the new firmware package compresses the firmware code into n frame data.

[0075] (1) The start symbol is used to determine whether there is a new firmware package in the storage module during the update process.

[0076] (2) There are two types of frame data in the new firmware package. One is copied from the old version of the APP, that is, the same code content, including the firmware copy address and copy data length of the old version of the APP. When it is parsed that the new firmware package contains the old version of the APP copy frame, the firmware code needs to be copied from the copy address in the pre-backup APP to the flash of the MCU. The other type of frame data is the newly added firmware block, that is, different code content. The newly added firmware block contains the newly added firmware content, which is compressed and needs to be decompressed and updated to the flash of the MCU.

[0077] (3) The firmware CRC check code is used to verify whether the firmware update of the old version of the APP is successful.

[0078] In the embodiment of the present application, if a new firmware package sent by the code management system is received, the new firmware package is stored in the storage module; wherein, the new firmware package is generated by the code management system according to the target update version and the current running version when it is determined that the current running version of the application is different from the target update version; the target update version is determined according to the obtained version information of the application. Switch the current running mode to the Bootloader mode. In the Bootloader mode, update the current running version of the application according to the new firmware package to obtain the updated application. In this solution, the code management system obtains the version information of the application, generates the most suitable target update version according to the version information, and determines whether the current running version is the target update version. If it is not the target update version, the code management system generates a new firmware package according to the target update version and the current running version, and sends the new firmware package to the embedded device. After receiving the new firmware package, the embedded device enters the Bootloader mode and updates the current running version of the application. Therefore, the size of the firmware upgrade package that needs to be downloaded during software update is greatly reduced, the data transmission efficiency of online upgrade is improved, the code management system automatically manages each version of the firmware by itself, avoiding incorrect updates, and solving the technical problem of low update efficiency of embedded devices.

[0079] Figure 4 FIG. is a schematic flowchart of another update processing method for an embedded device provided by an embodiment of the present application, which is applied to an embedded device on which an application is deployed, such as Figure 4 shown, the method includes:

[0080] Step 301, if a new firmware package sent by the code management system is received, store the new firmware package in the storage module; wherein, the new firmware package is generated by the code management system according to the target update version and the current running version when it is determined that the current running version of the application is different from the target update version; the target update version is determined according to the obtained version information of the application.

[0081] In an example, the version information includes software version information and hardware version information; the software version information is the information of the current running version; the new firmware package is generated by the code management system comparing the target version information of the target update version with the software version information of the current running version, copying the address information and length information of the same code content obtained by the comparison to the new firmware package, and writing the different code content obtained by the comparison into the new firmware package.

[0082] In an example, the new firmware package includes a start symbol, a frame number, frame data, and a firmware CRC check code.

[0083] Exemplarily, this step can be referred to Figure 1Step 101 in [the above] will not be elaborated further.

[0084] Step 302: Switch the current operating mode to the Bootloader mode.

[0085] Exemplarily, the embedded device can switch the current operating mode to the Bootloader mode.

[0086] Step 303: In the Bootloader mode, determine that there is a new firmware package in the storage module according to the start symbol in the new firmware package.

[0087] Exemplarily, in the Bootloader mode, the embedded device can determine whether there is a new firmware package in the storage module according to the start symbol in the new firmware package.

[0088] Step 304: According to the address information and length information of the same code content in the new firmware package, determine the backup address corresponding to the address information in the pre-backup backup program, copy the firmware code at the backup address to the application program; and decompress the different code content in the new firmware package, and update the decompressed content to the application program to obtain an updated application program.

[0089] Exemplarily, when the embedded device is updated, it needs to pre-backup and obtain a backup program, and then erase the current running version of the application program to be updated. Therefore, according to the address information and length information of the same code content in the new firmware package, determine the backup address corresponding to the address information in the backup program, and copy the firmware code at the backup address to the application program. And decompress the different code content in the new firmware package, and update the decompressed content to the application program to obtain an updated application program.

[0090] Step 305: According to the firmware CRC check code, check the target update version in the updated application program to obtain check result information; wherein, the check result information indicates whether the application program is updated successfully.

[0091] Exemplarily, Figure 5 is a data structure diagram of another update processing method for the embedded device provided by the embodiments of the present application. As Figure 5 shown, Figure 5 are the new firmware code and the old firmware code. The binary file (1, 4) blocks and (3, 6) blocks are the same parts, and the (2, 5) blocks are the different parts. When checking, the diff algorithm can be used to compare the two binary files. Regarding the same parts of the content, the position information and length information of the same parts in the original application program need to be written into another compressed file. Regarding the different parts, the code content of the different parts needs to be completely written into another compressed file. According to Figure 5It can be seen that 3 frames of data can be generated. The first frame is the old version APP copy frame, with the copy start address being 0 and the copy length being 1000. The second frame is the new firmware block frame, and the firmware block content is the gzip compressed data from the new firmware address 1000 to 1200, and the data length is the length after compression of 201 bytes. The third frame is the old version APP copy frame, with the copy start address being 1101 and the copy length being 1000.

[0092] In the embodiment of the present application, if a new firmware package sent by the code management system is received, the new firmware package is stored in the storage module; wherein, the new firmware package is generated by the code management system when it determines that the current running version of the application is different from the target update version, and the target update version is determined according to the obtained version information of the application. The current running mode is switched to the Bootloader mode. In the Bootloader mode, according to the start symbol in the new firmware package, it is determined that there is a new firmware package in the storage module. According to the address information and length information of the same code content in the new firmware package, the backup address corresponding to the address information in the pre-backup backup program is determined, and the firmware code at the backup address is copied to the application; and the different code content in the new firmware package is decompressed, and the decompressed content is updated to the application to obtain the updated application. According to the firmware CRC checksum, the target update version in the updated application is checked to obtain the check result information; wherein, the check result information indicates whether the application is updated successfully. Therefore, it greatly reduces the size of the firmware upgrade package that needs to be downloaded during software update, improves the data transmission efficiency of online upgrade, the code management system automatically manages each version of the firmware by itself, avoids incorrect updates, and solves the technical problem of low update efficiency of embedded devices.

[0093] In one example, Figure 6 is a schematic flowchart of another update processing method for an embedded device provided by the embodiment of the present application, as Figure 6As shown in the figure, it includes: start; the code management system reads the software and hardware version information from the embedded device; the code management system generates a new compressed package according to the version information; the embedded device obtains the new compressed package from the program management module and saves it to the specified storage area; the embedded device enters the Bootloader mode; determines whether the new compressed package contains a start symbol; if it contains a start symbol, determines whether the APP firmware code has been backed up; if it has been backed up, erases the APP firmware code; if it has not been backed up, backs up the APP firmware code; parses the new compressed package and writes it to the FALSH address of the APP; verifies the updated current APP firmware code; if it is determined that the verification is successful, switches to the APP mode; if it is determined that the verification fails, erases the updated current APP firmware code, rewrites the backed-up APP firmware code to the APP's flash, and erases the start symbol of the new compressed package.

[0094] Therefore, in the embodiment of the present application, the APP firmware code will be pre-backed up before firmware update to prevent the embedded device from malfunctioning after the update fails; moreover, compared with the firmware package partition upgrade in the prior art, in the present application, there is no need to configure the addresses of each module, and the implementation is simple, convenient and easy to operate.

[0095] In one example, Figure 7 is a storage information allocation diagram of an embedded device provided by an embodiment of the present application. As Figure 7 shown, 1 is used to store the Bootloader program, which is saved in the internal FLASH of the MCU; 2 is used to store the application program, which is saved in the internal FLASH of the MCU; 3 is used to back up the application program (which can be saved in the external FLASH); 4 is used to store the received new firmware package (which can be saved in the external FLASH).

[0096] Figure 8 is a schematic flowchart of another update processing method for an embedded device provided by an embodiment of the present application, which is applied to the code management system. As Figure 8 shown, the method includes:

[0097] Step 401, obtain the version information of the application program in the embedded device; and determine the target update version corresponding to the version information.

[0098] Step 402, if it is determined that the current running version of the application program is different from the target update version, generate a new firmware package according to the target update version and the current running version.

[0099] Step 403, send the new firmware package to the storage module of the application program, so that the application program switches its current running mode to the Bootloader mode, and in the Bootloader mode, update the current running version of the application program according to the new firmware package to obtain the updated application program.

[0100] The method of this embodiment can execute the technical solutions in the above method. The specific implementation process and technical principle are the same, and will not be elaborated here.

[0101] Figure 9 As shown in the flowchart of another update processing method for an embedded device provided by an embodiment of the present application, which is applied to a code management system, such as Figure 9 shown, the method includes:

[0102] Step 501, obtain the version information of the application program in the embedded device.

[0103] In one example, the version information includes software version information and hardware version information, and the software version information is the information of the currently running version.

[0104] Step 502, determine the target update version corresponding to the hardware version information.

[0105] Step 503, if it is determined that the currently running version of the application program is different from the target update version, then compare the target version information of the target update version with the software version information of the currently running version, copy the address information and length information of the same code content obtained by the comparison to the new firmware package, and write the different code content obtained by the comparison to the new firmware package.

[0106] In one example, the new firmware package includes a start symbol, the number of frames, frame data, and a firmware CRC check code.

[0107] Step 504, send the new firmware package to the storage module of the application program, so that the application program switches its current running mode to the Bootloader mode, and in the Bootloader mode, update the currently running version of the application program according to the new firmware package to obtain an updated application program.

[0108] In one example, the updated application program is obtained in the Bootloader mode of the embedded device. According to the start symbol in the new firmware package, it is determined that there is a new firmware package in the storage module; according to the address information and length information of the same code content in the new firmware package, the backup address corresponding to the address information in the pre-backup program is determined, and the firmware code at the backup address is copied to the application program; and the different code content in the new firmware package is decompressed, and the decompressed content is updated to the application program.
