[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] This application provides a firmware upgrade method, apparatus, device, and computer-readable storage medium. The firmware upgrade apparatus can be integrated into a device.

[0039] The following sections provide detailed descriptions of each example. It should be noted that the order in which the embodiments are described is not intended to limit the preferred order of the embodiments.

[0040] This application provides a firmware upgrade method applied to a first device, which may be a terminal or other device. The following description will focus on a first firmware upgrade device, which can be integrated into the device itself. Figure 1 As shown, the specific process of this firmware upgrade method can be as follows:

[0041] 101. Obtain the module upgrade file of the target module in the second device. The module upgrade file includes the firmware upgrade files corresponding to at least two firmwares in the target module.

[0042] The first device and the second device can be different devices. For example, the first device can be a terminal, and the second device can be a vehicle. Alternatively, the first device and the second device can be the same device. The specific configuration can be flexibly set according to needs and is not limited here.

[0043] The target module can be a module in the second device that provides a specified function, such as an Ultra Wideband (UWB) module, a fragrance control module, or an electric fan control module. The UWB module can detect living information in the vehicle, the fragrance control module can control the release of fragrance in the vehicle, and the electric fan control module can be used to control the operation of the vehicle's fan.

[0044] The module upgrade file may include firmware upgrade files for at least two firmware files in the target module. After the firmware upgrade file is written to the target module, the corresponding firmware can be upgraded. For example, the module upgrade file may include firmware upgrade files for at least two of the target module's configuration file, application file, and driver file (for example, it may be a firmware upgrade package).

[0045] 102. Send upgrade data packets to the control module of the second device according to the module upgrade file, and send the upgrade data packets to the target module through the control module so that the target module upgrades at least two firmwares.

[0046] The first device can communicate indirectly with the target module of the second device through the control module of the second device. The first device sends the upgrade data packet of the module upgrade file to the control module of the second device. Through the control module of the second device, the upgrade data packet is sent to the target module. The target module writes the data upgrade packet, thereby upgrading at least two firmware on the target module.

[0047] Upgrade data packages can be obtained by dividing the data of the module upgrade firmware. Each upgrade data package includes a portion of the data in the module upgrade firmware file. Multiple module upgrade data packages corresponding to the module upgrade file can be merged to obtain the module upgrade file.

[0048] In this embodiment of the application, the module upgrade file includes firmware upgrade files for multiple firmware (at least two) of the target module, and multiple firmware of the target module can be upgraded through one module upgrade file.

[0049] The module upgrade file includes firmware upgrade files for multiple firmware versions of the target module. The write location of each firmware upgrade file can be included in each upgrade data packet. After receiving the upgrade data packet, the target module parses the upgrade data packet to obtain the firmware upgrade data and the write location of the firmware upgrade data, and writes the firmware upgrade data according to the write location.

[0050] Optionally, the module upgrade file may further include a firmware manifest, which may include the address of each firmware upgrade file in the module upgrade file within the target module. In one embodiment, the module upgrade file includes a first upgrade data packet and a second upgrade data packet. The first upgrade data packet includes the firmware manifest, and the second upgrade data packet includes partial data of the firmware upgrade files. The step of "sending the upgrade data packet to the control module of the second device according to the module upgrade file, and sending the upgrade data packet to the target module through the control module" may include:

[0051] The first upgrade data packet is sent to the control module, and then sent to the target module through the control module. The firmware manifest includes the write location of each firmware upgrade file in the target module.

[0052] Multiple second upgrade data packets are sequentially sent to the target module through the control module, so that the target module writes the second upgrade data packets to the target module based on the write position in the firmware manifest.

[0053] The module upgrade file includes a first upgrade data package and a second upgrade data package. The first upgrade data package includes a firmware manifest. There can be one or more first upgrade data packages. The number of first upgrade data packages depends on the size of the firmware manifest. If the firmware manifest is large, there can be multiple first upgrade data packages.

[0054] The second upgrade data packet may contain part of the data in the firmware upgrade file. It can be obtained by splitting the firmware upgrade file into multiple data packets with a smaller data size than the firmware upgrade file.

[0055] After the first device sends the first upgrade data packet to the target module through the control module, it then sends the second upgrade data packet to the target module through the control module. The target module can obtain the firmware manifest by parsing the first upgrade data packet, and can determine the write location of each second upgrade data in the target module based on the firmware manifest.

[0056] Splitting a module upgrade file into multiple data upgrade packages can be done by splitting the module upgrade file based on a preset data volume threshold, resulting in multiple upgrade data packages with a data volume less than or equal to the data volume threshold.

[0057] For example, the framework of a module upgrade package can be as follows: Figure 2 As shown, the module upgrade file includes a firmware manifest and multiple firmware upgrade files. The firmware manifest records the position of each firmware upgrade file in the module upgrade (e.g., the starting position), the size of each firmware upgrade file, the address of each firmware upgrade file in the target module's chip (e.g., the starting address), the number of firmware upgrade files, and the decryption key for the upgrade data package, etc.

[0058] Optionally, before the first device sends the upgrade data packet according to the data size limit of the target module and sends the upgrade data packet to the control module of the second device according to the module upgrade file, the method further includes:

[0059] Determine the threshold amount of data the target module can receive for the upgrade data packet;

[0060] Based on the threshold of received data volume, each firmware upgrade file in the target module's module upgrade file is split into multiple upgrade data packets.

[0061] The received data volume threshold is the threshold for the data length of each data packet for the target module. The received data volume threshold can be set in advance based on the memory information of the target module, or it can be determined by the control module based on the data transmission characteristics or memory usage of the target module. For example, if the total number of upgrade data packets for the module upgrade file is required to not exceed the preset data packet number threshold, then the maximum data volume of each upgrade data packet can be calculated based on the total number of module upgrade files and the preset number of packets threshold to obtain the received data volume threshold. Alternatively, the data volume of the data packets that the target module can receive can be determined based on the memory usage of the target module to obtain the received data volume threshold.

[0062] The first device splits each firmware upgrade file in the target module's module upgrade file into multiple upgrade data packets based on the target module's threshold for the amount of data received for upgrade data packets. The data amount of each upgrade data packet is less than or equal to the data amount threshold.

[0063] Optionally, the first device can generate an upgrade data package from the firmware manifest and split each firmware upgrade file to obtain multiple upgrade data packages.

[0064] The module upgrade package can be a corresponding module upgrade package obtained by the first device according to the target module that the second device needs to upgrade (e.g., obtained from a server or from local storage). Optionally, it can also be extracted by the first device from the upgrade package of the second device. The upgrade package includes module upgrade files for multiple modules of the second device, and the second device obtains the module upgrade file corresponding to the target module from it. That is, in one embodiment, before the step "obtaining the module upgrade file of the target module in the second device", the firmware upgrade method provided in this application embodiment may further include:

[0065] Obtain the firmware upgrade package for the second device, which includes module upgrade files for multiple modules of the second device;

[0066] Based on the firmware version of each module in the second device and the firmware version of the module upgrade file, determine the modules of the second device to be upgraded.

[0067] Identify the target module from the modules to be upgraded.

[0068] For example, the first device can obtain the firmware upgrade package of the second device. The firmware upgrade package includes module upgrade files for multiple modules of the second device. Based on the firmware upgrade package, the firmware version of each firmware upgrade file in the module upgrade file of each module is determined.

[0069] Obtain the firmware version of each module application of the second device, as well as the firmware version of each firmware upgrade file in the corresponding module upgrade text file, and determine the module that needs to be upgraded, i.e. the module to be upgraded.

[0070] Then, determine the target module for the current firmware upgrade from the modules to be upgraded.

[0071] After the module upgrade file is sent to the target module via the control module, it can be verified whether the target module has completed the firmware upgrade. If the target module has completed the firmware upgrade, the firmware upgrades of other modules of the second device can be performed. That is, in one embodiment, after the step "sending the upgrade data packet to the control module of the second device according to the module upgrade file, and sending the upgrade data packet to the target module via the control module", the method further includes:

[0072] The control module obtains the current firmware version of each firmware in the target module.

[0073] If the firmware version currently used by each firmware in the target module is the same as the firmware version of each firmware upgrade file in the module upgrade text file, then a new target module is determined from the modules to be upgraded.

[0074] Return to the step of obtaining the module upgrade file for the target module, until the firmware of each module to be upgraded on the second device is upgraded.

[0075] For example, the first device can obtain the current firmware version of each firmware of the target module through the control module; compare the current firmware version of each firmware of the target module with the version of the firmware upgrade file in the module upgrade file. If they are the same, it means that the target module has completed the firmware upgrade. Then, a new target module is determined from the modules to be upgraded, and the execution of step 101 is returned to obtain the module upgrade file of the new target module. Based on the module upgrade file of the new target module, the firmware upgrade of the new target module is performed. This process is repeated until all modules to be upgraded have completed the firmware upgrade.

[0076] In one embodiment, after the first device sends the entire data upgrade package of the module upgrade file of the target module to the target module, it can request the target module to perform memory verification to ensure that the target module has written the firmware upgrade file. That is, the firmware upgrade method provided in this application embodiment may further include:

[0077] In response to the completion of the module upgrade file transmission, a memory verification request is sent to the target module through the control module. The memory verification request instructs the target module to verify the written firmware upgrade file and returns the memory verification result to the first device through the control module.

[0078] The upgrade result of the target module is determined based on the memory verification result returned by the target module.

[0079] For example, the first device checks whether all upgrade data in the upgrade file of the detection module has been sent to the target module. If so, it sends a memory verification request to the target module through the control module.

[0080] After receiving the memory verification request, the target module verifies the data at the write position of each firmware upgrade file. For example, it performs byte-by-byte operations on the data at the write position of the firmware upgrade file (such as accumulation, XOR operation, etc.) to obtain the memory verification result and returns the memory verification result to the first device.

[0081] The first device determines the upgrade result of the target module based on the memory verification result returned by the second device. Specifically, the first device can perform the same byte-by-byte operation on the firmware upgrade file in the module upgrade file as on the target module, and compare the operation result with the memory verification result returned by the target module. If they match, the target module has completed the firmware upgrade.

[0082] In one embodiment, the module upgrade file is generated through the following steps:

[0083] The system acquires multiple firmware upgrade files from the second device, along with upgrade information for each file, including file size and write location. It then groups these firmware upgrade files to obtain at least two firmware upgrade files for each module. Based on the upgrade information from these two files, it generates a firmware manifest for each module. Finally, it merges these two firmware upgrade files to obtain a merged firmware upgrade file for each module. Finally, it generates a module upgrade file for each module based on the merged firmware upgrade file and the firmware manifest.

[0084] As can be seen from the above, the embodiments of this application obtain the module upgrade file of the target module in the second device, which includes firmware upgrade files corresponding to at least two firmwares in the target module; send upgrade data packets to the control module of the second device according to the module upgrade file, and send the upgrade data packets to the target module through the control module, so that the target module upgrades at least two firmwares. This can realize the upgrading of multiple firmwares in the target module of the second device through one module upgrade file, thereby improving the firmware upgrade efficiency.

[0085] This application embodiment also provides another firmware upgrade method, applied to a target module of a second device. The second device may further include a control module. The second device can be a device requiring firmware upgrade, such as a vehicle. The following description will focus on a second firmware upgrade device, which can be integrated into the target module. Figure 3 As shown, the specific process of this firmware upgrade method can be as follows:

[0086] 201. Receive an upgrade data packet sent by the first device through the control module. The upgrade data packet is sent by the first device based on the module upgrade file of the target module. The target upgrade file includes firmware upgrade files corresponding to at least two firmwares in the target module.

[0087] For example, the target module can control the upgrade data packets sent by the control module. The upgrade data packets sent by the control module can be sent by the first device based on the module upgrade file of the target module. The module upgrade file includes firmware upgrade files of at least two firmwares of the target module. The first device divides the data of the module upgrade firmware to obtain multiple upgrade data packets.

[0088] 202. Determine the write location of the upgrade data packet.

[0089] For example, the target module of the second device determines the firmware corresponding to the upgrade data packet, and determines the write location of the upgrade data packet based on the corresponding firmware.

[0090] Optionally, the target module can determine the write location of the upgrade data packet based on the firmware manifest sent by the first device through the control module. The firmware manifest may contain the upgrade data packet sent by the first device through the control module, specifically it may be included in the first upgrade data packet. That is, in one embodiment, the upgrade data includes a first upgrade data packet and a second upgrade data packet. The first upgrade data packet includes the firmware manifest, and the second upgrade data packet includes part of the firmware upgrade file data. The step "determine the write location of the upgrade data packet" may include:

[0091] Based on the firmware list in the first upgrade data package, determine the write location of the second upgrade data package;

[0092] Step 203, "Write the upgrade data packet according to the write location," includes:

[0093] Write the second upgrade data packet into the target module according to the write location.

[0094] The target module can obtain a firmware manifest by parsing the first upgrade data packet. Based on the firmware manifest, the write position of each second upgrade data in the target module can be determined, and the second upgrade data packet is written into the target module according to the write position.

[0095] 203. Write an upgrade data packet according to the write location to upgrade at least two firmware versions of the target module.

[0096] For example, the target module can write data upgrade packages one by one according to the write address of each data upgrade package, thereby upgrading at least two firmware on the target module.

[0097] The module upgrade file can be split into multiple upgrade data packets. These multiple upgrade data packets are sent sequentially to the target module. Each upgrade data packet can be sent to the target module after the previous upgrade data packet has been written to it. That is, in one embodiment, after the step "write upgrade data packets according to the writing position", the firmware upgrade method provided in this application embodiment further includes:

[0098] In response to the completion of writing the upgrade data packet, a feedback signal is sent to the first device through the control module. The feedback signal is used to instruct the first device to send the next upgrade data packet.

[0099] Return to the step of receiving the upgrade data packet sent by the first device through the control module of the second device, until the upgrade data packet corresponding to the module upgrade file is sent.

[0100] For example, after writing the upgrade data packet into the chip in the target module according to the writing position, the target module sends a feedback signal to the control module. The control module sends the feedback signal to the first device, which can instruct the first device to send the next upgrade data packet. After receiving the feedback signal, the first device can send the next upgrade data packet. The target module receives the next upgrade data packet sent by the first device and sends feedback information to the first device after the upgrade data packet is written. This process is repeated until all upgrade data packets of the module upgrade file are sent to the target module.

[0101] As can be seen from the above, this embodiment of the application receives an upgrade data packet sent by the first device through the control module. The upgrade data packet is sent by the first device based on the module upgrade file of the target module. The target upgrade file includes firmware upgrade files corresponding to at least two firmwares in the target module. The write position of the upgrade data packet is determined. The upgrade data packet is written according to the write position to upgrade at least two firmwares of the target module. This can realize the upgrade of multiple firmwares in the target module of the second device through a single module upgrade file, thereby improving the firmware upgrade efficiency.

[0102] This application embodiment also provides another firmware upgrade method, applied to the control module of a second device. The second device may further include a target module for the firmware to be upgraded. This embodiment will be described from the perspective of a firmware upgrade device, which can be integrated into the control module, such as... Figure 4 As shown, the specific process of this firmware upgrade method can be as follows:

[0103] 301. Receive an upgrade data packet sent by the first device based on the module upgrade file of the target module, wherein the module upgrade file includes firmware upgrade files corresponding to at least two firmwares in the target module.

[0104] The first device can communicate indirectly with the target module of the second device through the control module of the second device, and the first device sends the upgrade data packet of the module upgrade file to the control module of the second device.

[0105] 302. Send the upgrade data package to the target module so that the target module upgrades at least two firmware versions.

[0106] The control module sends the upgrade data packet to the target module so that the target module can write the data upgrade packet, thereby upgrading at least two firmware versions on the target module.

[0107] The upgrade data packet sent by the first device can be obtained by splitting the module upgrade file based on a preset data volume threshold, and the data volume of the upgrade data packet is less than or equal to the data volume threshold.

[0108] The first device can also send upgrade data packets based on the data volume limit of the target module. The first device can obtain the data volume threshold for the target module to receive upgrade data packets through a data volume confirmation request. That is, in one embodiment, before the step of "receiving the upgrade data packet sent by the first device based on the module upgrade file of the target module", the firmware upgrade method provided in this application embodiment can also include:

[0109] Receive a data volume confirmation request sent by the first device;

[0110] Based on the data volume confirmation request, and based on the target module's memory information and the total data volume of the module upgrade file, determine the threshold for the target module to receive the upgrade data packet.

[0111] The system returns a received data volume threshold to the first device, instructing the first device to split the module upgrade file based on the received data volume threshold to obtain multiple upgrade data packets.

[0112] The first device can send a data volume confirmation request to the control module. After receiving the data volume control request, the control module determines the data volume threshold for the target module to receive the upgrade data packet based on the memory information of the target module and the total data volume of the module upgrade file, and returns the data volume threshold to the first device.

[0113] The received data volume threshold can be set in advance based on the memory information of the target module. The control module obtains the preset received data volume threshold from memory based on the identifier of the target module.

[0114] The control module can also determine the data size based on the target module's memory information (e.g., memory usage). For example, if the target module requires that the total number of upgrade data packets for the module upgrade file not exceed a preset data packet number threshold, then the control module can calculate the maximum data size of each upgrade data packet based on the total number of module upgrade files and the preset data packet number threshold, thus obtaining the received data size threshold. Alternatively, the control module can determine the size of the data packets that the target module can receive based on the target module's memory usage, thus obtaining the received data size threshold.

[0115] After the first device receives the data volume threshold, it can split each firmware upgrade file in the target module's module upgrade file into multiple upgrade data packets according to the target module's data volume threshold for receiving upgrade data packets. The data volume of each upgrade data packet is less than or equal to the data volume threshold.

[0116] As can be seen from the above, the embodiments of this application receive an upgrade data packet sent by the first device based on the module upgrade file of the target module, the module upgrade file including firmware upgrade files corresponding to at least two firmwares in the target module; and send the upgrade data packet to the target module so that the target module upgrades at least two firmwares; thus, it is possible to upgrade multiple firmwares in the target module of the second device through one module upgrade file, thereby improving firmware upgrade efficiency.

[0117] Based on the above embodiments, in order to more clearly illustrate the firmware upgrade method provided in this application, the interaction between the target module of the first device and the second device and the control module of the second device is further described below, such as... Figure 5 As shown, the interaction flow between the first device, the target module of the second device, and the control module of the second device can be as follows:

[0118] The first device obtains module upgrade files for multiple modules of the second device from the server, and assigns a number to each firmware upgrade file in the module upgrade files according to the number agreed upon with the second device.

[0119] The first device obtains the firmware version of each module on the second device through the control module, compares the firmware version of each module on the second device with the firmware version of the firmware upgrade file, and determines the module on the second device that needs to be upgraded.

[0120] The first device sends a security verification request related to firmware upgrade to the control module.

[0121] The control module generates a security verification code and returns it to the first device.

[0122] The first device performs post-encryption on the security verification code and sends the encrypted security verification code to the control module.

[0123] After receiving the encrypted security verification code, the control module decrypts the encrypted security verification code, compares the decrypted security verification code with the locally stored security verification code, and returns the comparison result to the second device.

[0124] If the security verification is successful, the first device will determine the target module from the modules to be upgraded.

[0125] The first device sends a storage area erase command to the control module.

[0126] Upon receiving the instruction, the control module instructs the target module to erase the data in the area to be written to the firmware upgrade file.

[0127] After the target module completes the erasure, it sends the erasure result to the control module, which then feeds back the erasure result to the first device.

[0128] After receiving the result of successful erasure, the first device sends a data volume confirmation request to the control module.

[0129] After receiving the data volume confirmation request, the control module will provide a data volume threshold.

[0130] The first device splits the firmware upgrade file into several upgrade data packets based on the threshold of the amount of received data.

[0131] The first device sends upgrade data packets to the control module sequentially. Each time the control module receives an upgrade data packet, it sends the upgrade data packet to the target module.

[0132] The target module parses the upgrade data packet and extracts the firmware list.

[0133] After the target module obtains the firmware list, the first device continues to send the undelivered upgrade package data to the control module in sequence.

[0134] Each time the control module receives a data packet, it transmits the data to the target module.

[0135] The target module writes the corresponding firmware to the corresponding location according to the manifest information. After the writing is completed, it sends the writing result back to the control module, which then sends the writing result back to the first device.
