[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] The inventors of the present application noticed in their research that, during the firmware OTA upgrade process, the server background obtains the latest firmware version information by manually uploading the new firmware upgrade package and filling in the new firmware configuration file to describe the firmware version. Therefore, errors may occur in manually uploading the new firmware version, but the firmware version information in the configuration file describing the new firmware is correct, resulting in an abnormal situation in which the actual firmware version issued is inconsistent with the expected firmware version, which in turn causes the firmware upgrade to fail or functional abnormalities.

[0041] For terminals, traditional firmware OTA upgrades usually go through the following steps: 1. Version detection, the terminal regularly checks or the user manually checks whether there is a new firmware version available for update; 2. Downloading the firmware, after starting the firmware update process, the terminal sends a request to the server through the network to download the new firmware; 3. Updating the firmware, after the download is complete, the terminal prompts the user to confirm whether to start the upgrade, and the terminal writes the new firmware to the corresponding storage area for updating. After the update is completed, the terminal will restart to load the new firmware; 4. Verifying the upgrade result, the terminal detects the correctness of the version information of the new firmware during the restart process to ensure that the new firmware can work normally. If the firmware upgrade fails or there is a problem with the firmware, the terminal will revert to the old version; 5. Feedback on the upgrade result, the terminal will feedback the upgrade result to the server.

[0042] In the MCU chip, the firmware version information is stored after the interrupt vector table, but the specific location is not fixed, and the firmware version information may change as the program changes position. The correctness of the new firmware version can only be verified after the new firmware is installed. This firmware update method takes a long time, is inefficient, and has the risk of update failure.

[0043] Based on this, the present application provides a terminal firmware online upgrade method, a firmware generation method and a device, by setting the firmware version information after the interrupt vector table and adjacent to the interrupt vector table, and setting the interrupt vector table and the firmware version information at the starting position of the new firmware file (i.e., the executable file), thereby realizing rapid acquisition of the firmware version information of the new firmware, reading the firmware version information in the form of reading a file, and at the same time improving the efficiency and convenience of firmware updating and maintenance.

[0044] For ease of understanding, the terms involved in the embodiments of the present application are explained below:

[0045] Firmware files are the storage form of firmware and are the digital representation of firmware programs. They contain the necessary instructions and parameters to run on the device. The firmware file structure refers to the organization of firmware files in the system. It usually contains all the code, data, and configuration information required to perform specific functions. Different devices and MCU chips may have different firmware file structures.

[0046] The firmware file structure generally includes: code segment and data segment.

[0047] The interrupt vector table is a data structure used to map interrupt or exception types to the addresses of corresponding interrupt service routines. The interrupt vector table usually includes: interrupt vectors and interrupt service routine addresses, etc. Among them, the interrupt vector is a unique identifier for each interrupt, usually arranged in a certain order, such as hardware interrupts, software interrupts, and exceptions; the interrupt service routine address is that for each interrupt vector, there is a corresponding address pointing to the service routine that handles the interrupt. When an interrupt occurs, the processor will look up the interrupt vector table, find the corresponding address according to the interrupt type, and jump to the address to execute the code. Among them, the interrupt vector table contains multiple address offsets, each offset corresponds to the entry address of an interrupt service program.

[0048] The link files in the firmware file usually refer to the link files related to the firmware image file, which are various auxiliary files designed to help developers build and debug firmware.

[0049] The target constant data of the firmware file is immutable data that will not be modified during the execution of the firmware, such as firmware version information, hardware configuration data, system parameters, and configuration settings.

[0050] In the present application, since the size of the interrupt vector table in the platform (certain models of MCU) to which the firmware (i.e., executable file) is adapted is fixed, the offset of the target constant data after the interrupt vector table and adjacent to the interrupt vector table is also fixed, so that the target constant data, such as firmware version information, can be subsequently obtained by reading the size of the interrupt vector table in the first package data downloaded from the firmware.

[0051] Link script is a compilation technology that converts the source program from one language (source language) to a target language (target language).

[0052] Firmware version information includes version number, release date, manufacturer, and update content. The version number is a unique code used to identify the firmware and is used to distinguish different firmware versions.

[0053] Figure 1The flowchart of a firmware generation method provided in the embodiment of the present application is shown in FIG. 1 , wherein the execution subject of the method is a PC compiler. Figure 1 As shown, the method may include:

[0054] Step S110 , obtaining a link script, wherein the link script is used to indicate that the target constant data is set after the interrupt vector table, and the start address of the target constant data is adjacent to the end address of the interrupt vector table.

[0055] The internal data of the firmware file includes other data such as the interrupt vector table and the constant data area, wherein the constant data area includes multiple immutable data, such as firmware version information, hardware configuration data, system parameters and other data.

[0056] The target constant data is any data in the constant data area.

[0057] The target constant data is set after the interrupt vector table and adjacent to the interrupt vector table, and the target constant data in the firmware file can be quickly and accurately obtained through the size of the interrupt vector table.

[0058] Furthermore, in order to achieve fast access and retrieval of target constant data, the interrupt vector table and target constant data are set at the file start position of the firmware file, thereby improving the system startup speed and operation effect and reducing the performance loss caused by data access delay.

[0059] Among them, the address offset of the target constant data is obtained based on the size of the interrupt vector table, and the target constant data is read through the address offset of the target constant data, so that the target constant data is read in the form of reading a file. It can be achieved that the target constant data can be obtained without starting the firmware file, which improves the efficiency of data reading and reduces the complexity of data processing.

[0060] In some optional embodiments, determining the address offset of the target constant data based on the data length of the interrupt vector table includes:

[0061] Get the starting address of the interrupt vector table;

[0062] Based on the start address of the interrupt vector table and the data length of the interrupt vector table, an address offset is obtained, and the address offset is the address offset of the target constant data.

[0063] Among them, the starting address and data length of the interrupt vector table can be obtained through a specific system call. By obtaining the starting address of the interrupt vector table, and then calculating the ending address of the interrupt vector table according to the starting address of the interrupt vector table and the data length of the interrupt vector table, the address offset of the target constant data is obtained, so as to conveniently locate the location of the target constant data and realize efficient management of the interrupt vector table and its associated data.

[0064] Step S120: Based on the link script, a firmware file is obtained in which the target constant data is set after the interrupt vector table.

[0065] In a possible embodiment, in step S140, based on the link script, a firmware file is obtained in which the target constant data is set after the interrupt vector table, including:

[0066] Get the first data block where the interrupt vector table is located;

[0067] Get the second data block where the target constant data is located;

[0068] Based on the link script, the second data block is located after the first data block and adjacent to the first data block, so as to obtain a firmware file in which the target constant data is set after the interrupt vector table.

[0069] By modifying the link script, the target constant data is set after the interrupt vector table and adjacent to the interrupt vector table. This allows the target constant data to be obtained without starting the firmware file, thereby improving the efficiency of data reading.

[0070] For example, declare the interrupt vector table in a corresponding segment named ".isr_vt";

[0071] Declare the firmware version information into a fixed-size array and specify the segment name of the array as CodeVersion:

[0072] Eg.cosnt uint8_t g_app_version

[32] __attribute__((section(CodeVersion)))="NOR_V1.0.0"

[0073] Then, through the compilation technology, the compilation link file is modified to set the firmware version information after the interrupt vector table and adjacent to the interrupt vector table.

[0074] Among them, the link file extension of gcc is lds, and the link file is used to set various data blocks inside the firmware.

[0075] Based on Eg., compile the link file, modify the firmware's running start address on the target device (0x01032000), and ensure that the ORIGIN and LENGTH of the CODEVERSION part correspond to the ORIGIN of the ISRVECTOR part. That is, the ORIGIN value corresponding to CodeVersion is the firmware version information set after the interrupt vector table and adjacent to the interrupt vector table, and the offset value of the firmware version information is equal to the ORIGIN+LENGTH of ISRVECTOR.

[0076] Finally, save the modified link file and recompile to generate the firmware file.

[0077] A firmware generation method in the present application sets the target constant data after the interrupt vector table and adjacent to the interrupt vector, generates a corresponding link file based on a link script, further recompiles the firmware file, and finally obtains the firmware file; and achieves the technical effect of small code changes and no impact on program processing logic. At the same time, since it does not rely on the constant data storage address, it has high adaptability and significantly improves the compatibility and convenience of the firmware file.

[0078] Figure 2 The present invention provides a method for online terminal firmware upgrade, the execution subject of the method is a terminal, and the terminal can be a phone, a laptop computer, a tablet computer, etc. Figure 2 As shown, the method may include:

[0079] S210: Acquire a new firmware file information package and acquire first firmware version information, wherein the new firmware file is obtained by the above-mentioned firmware generation method, and the first firmware version information is firmware version information that the terminal is expected to upgrade.

[0080] When the firmware is upgraded online, the terminal can send a download request to the server through the network so that the server can send the new firmware, or the server can send the new firmware to the terminal by itself through the network.

[0081] In order to improve download efficiency and reduce the number of retransmissions triggered by download failures, the firmware data of the new firmware can be downloaded to the terminal in sequence by means of packet download.

[0082] Further, through the firmware generation method, the firmware version information is set after the interrupt vector table and adjacent to the interrupt vector table. Based on the data length of the interrupt vector table, the address offset of the firmware version information is determined. Based on the link script, a link file is obtained in which the firmware version information is set after the interrupt vector table, and the firmware file is recompiled to obtain a new firmware file, such as Figure 3 As shown, the internal data layout of the new firmware is shown. Figure 4The following is a comparison of the internal data layout of the new firmware and the traditional firmware.

[0083] In a possible embodiment, obtaining the new firmware file and the first firmware version information includes:

[0084] Get the configuration file corresponding to the new firmware file;

[0085] The first firmware version information is read from the configuration file.

[0086] Before obtaining the new firmware file, the terminal first obtains the first firmware version information in the configuration file corresponding to the new firmware file, and the first firmware version information is the firmware version information that the terminal is expected to upgrade.

[0087] S220. Obtain the firmware version information address offset according to the size of the interrupt vector table of the new firmware file information packet to obtain second firmware version information, wherein the second firmware version information is the version information of the new firmware file.

[0088] In a possible embodiment, obtaining the firmware version information address offset according to the size of the interrupt vector table of the new firmware file to obtain the second firmware version information includes:

[0089] Get the interrupt vector table of the new firmware file;

[0090] According to the size of the interrupt vector table, the address offset of the firmware version information is obtained;

[0091] Based on the firmware version information address offset, the second firmware version information is read.

[0092] For example, when obtaining the second firmware version information of the new firmware by reading data, the first 4K data of the new firmware file is read as a byte array, and the second firmware version information of the new firmware is obtained according to the address offset of the firmware version information. The data length of the interrupt vector table of a certain MCU chip is (71*4)=284, then the address offset of the firmware version information relative to the interrupt vector table is 284, which is the data length of the interrupt vector table.

[0093] S230: Obtain a verification result based on the first firmware version information and the second firmware version information, and determine that the terminal firmware is to be upgraded online based on the verification result.

[0094] When the server issues the new firmware, it manually uploads the upgrade package of the new firmware file to the server, and when uploading the upgrade package of the new firmware file, it is necessary to fill in the configuration file of the new firmware file to indicate the firmware version, so the first firmware version information in the configuration file is different from the second firmware version information in the new firmware file. Therefore, it is necessary to verify whether the second firmware version information of the new firmware file is correct based on the first firmware version information.

[0095] Specifically, if the first firmware version information matches the second firmware version information, the terminal firmware is upgraded online; if they do not match, the online upgrade is exited and an upgrade failure is prompted.

[0096] In the present application, the new firmware is downloaded in sub-packages, and the sub-package data of the new firmware is updated package by package, that is, updated while downloading.

[0097] The present application provides a terminal firmware online upgrade method, which obtains a new firmware file through an existing firmware generation method, obtains a firmware version information address offset according to the size of an interrupt vector table of an information packet of the new firmware file, so as to obtain second firmware version information, and uses the first firmware version information to verify whether the second firmware version is correct. If correct, the terminal firmware is upgraded online, that is, the version information of the new firmware file itself can be obtained without starting the firmware file, and after obtaining the first packet (i.e., information packet) data of the new firmware file, it can be determined whether the firmware version of the actually issued new firmware file is consistent with the firmware version information of the terminal expected to be upgraded, thereby ensuring the accuracy and security of the upgrade, and the operation is simple, which greatly reduces the difficulty of operation. The method can be widely used in firmware management systems, simplify the version upgrade process, and enhance the user's operating experience.

[0098] When the firmware needs to be ported to a new MCU platform, different platforms may have different Flash address ranges. Since the location of the version information in the technical solution of this application is fixed and close to the interrupt vector table, there is no need to worry about the change of the Flash address during the porting process.

[0099] Corresponding to the above method, the embodiment of the present application also provides a terminal firmware online upgrade device, such as Figure 5 As shown, the device comprises:

[0100] The download module 310 is used to obtain a new firmware file and first firmware version information, wherein the new firmware file is obtained by the above-mentioned firmware generation method, and the first firmware version information is the firmware version information that the terminal is expected to upgrade;

[0101] The acquisition module 320 is used to acquire the firmware version information address offset according to the size of the interrupt vector table of the new firmware file information packet to obtain the second firmware version information, wherein the second firmware version information is the version information of the new firmware file;

[0102] The verification module 330 obtains a verification result based on the first firmware version information and the second firmware version information, and determines that the terminal firmware is to be upgraded online based on the verification result.

[0103] In a possible embodiment, the download module 310 is further used for:

[0104] Get the configuration file corresponding to the new firmware file;

[0105] The first firmware version information is read from the configuration file.

[0106] In a possible embodiment, the acquisition module 320 is further configured to:

[0107] Get the interrupt vector table of the new firmware file;

[0108] According to the size of the interrupt vector table, the address offset of the firmware version information is obtained;

[0109] Based on the firmware version information address offset, the second firmware version information is read.

[0110] In a possible embodiment, the verification module 330 is further configured to:

[0111] If the first firmware version information matches the second firmware version information, the terminal firmware is upgraded online.
