[0042] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0043] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0044] Hex files are currently the most commonly used executable files in the automotive electronics industry. Code developed by developers in an embedded development environment is compiled and linked to generate a Hex file, which is then downloaded to the MCU for execution. With the increasing electrification and intelligence of automotive electronics, software functions are constantly being added and enriched, and Over-The-Air (OTA) technology has gradually become a standard feature in automobiles. However, many compilers for MCU chips generate Hex files with address misalignment. Due to the characteristics of flash memory, if the addresses are misaligned, the data at that address cannot be written to the flash memory, causing data writing failures. It should be noted that the contents of Hex files are all hexadecimal codes; for example, 0x8030010C and 0x803000E0 are both hexadecimal. Taking the Infineon TC397 chip as an example, the address required for writing to the program flash (PFLASH) must be 32-byte aligned. For instance, 0x8030010C is not divisible by 32, so this address cannot be directly used to operate the PFLASH without 32-byte alignment. However, 0x803000E0 is divisible by 32, so this address can be directly used to operate the PFLASH. If the lower-level machine, i.e., the bootloader, handles the address misalignment problem, it will have a significant impact on the writing time and efficiency.
[0045] In one example, existing methods for aligning Hex file addresses use either Hexview software or manual calculation to modify the Hex file. Both methods have limitations and need improvement in efficiency: using Hexview software or manually modifying the Hex file can only modify one or a few lines of addresses at a time. If there are dozens or even hundreds of misaligned lines of addresses in the Hex file, this method becomes unsuitable and extremely inefficient. If manual calculation leads to incorrect address modifications, it can cause program crashes during the flashing process, which is unacceptable for automotive electronics with extremely high safety requirements.
[0046] Therefore, this application provides a vehicle data processing method to solve the above-mentioned technical problems.
[0047] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.
[0048] Figure 1 A flowchart of a vehicle data processing method provided in an embodiment of this application is shown below. Figure 1 As shown, the method includes:
[0049] 101. Read the file to be processed and perform data parsing on the file to determine the data segments in the file to be processed; wherein, the file to be processed includes N data segments, where N is a positive integer greater than zero, and each data segment includes vehicle execution data and data address.
[0050] For example, the executing entity of this embodiment can be an electronic device, a cloud server, a terminal device, or other apparatus or device capable of executing this embodiment, and there is no limitation thereto. This embodiment is described with an electronic device as the executing entity.
[0051] The electronic device reads the file to be processed, namely the Hex file to be processed, and performs data parsing processing on the file to be processed. The parsing determines N data segments in the file to be processed, where N is a positive integer greater than zero. Each data segment includes vehicle execution data and the data address corresponding to the vehicle execution data. The vehicle execution data can be the program and data required for the vehicle MCU to run.
[0052] 102. Identify the target data segment in the file to be processed, perform data modification processing on the data address in each target data segment to obtain the modified data address; and perform position movement processing on the vehicle execution data of the corresponding target data segment according to the modified data address to generate the updated target data segment. The target data segment is the data segment in the file to be processed whose data address does not meet the preset address identification conditions.
[0053] For example, target data segments in each data segment of the file to be processed whose data addresses do not meet preset address recognition conditions are identified. For each target data segment, the data addresses corresponding to the vehicle execution data that do not meet the preset address recognition conditions are processed by data modification, such as padding or altering data addresses that cannot be recognized by the storage device, to obtain modified data addresses. This modified data addresses can be accurately identified and read. Because the data addresses have changed, the vehicle execution data corresponding to the data addresses of the target data segments must also be moved along with the modified data addresses, so that storage devices such as FLASH can accurately read the corresponding vehicle execution data based on the modified data addresses. After completing the movement processing of the vehicle execution data, the updated target data segments are generated.
[0054] 103. Based on the updated target data segment, perform file update processing on the file to be processed to generate the target file.
[0055] For example, after the target data is updated, the file to be processed also changes. Therefore, based on the updated target data segment, the file to be processed is updated to generate the target file.
[0056] In summary, the vehicle data processing method provided in this embodiment involves the following steps: reading the file to be processed and performing data parsing processing on the file to determine each data segment in the file to be processed; wherein each data segment includes vehicle execution data and data address; identifying the target data segment in the file to be processed, performing data modification processing on the data address in each target data segment to obtain the modified data address; and performing position shift processing on the vehicle execution data of the corresponding target data segment according to the modified data address to generate an updated target data segment, wherein the target data segment is the data segment in the file to be processed whose data address does not meet the preset address identification conditions; and performing file update processing on the file to be processed according to the updated target data segment to generate the target file. This process improves the accuracy and efficiency of Hex file rewriting.
[0057] Figure 2 A flowchart of another vehicle data processing method provided in the embodiments of this application is shown below. Figure 2 As shown, the method includes:
[0058] 201. In response to a user command on a preset interface, read the file to be processed according to the storage location indicated by the user command; wherein, the user command is used to indicate the storage location of the file to be processed.
[0059] For example, before the storage device FLASH reads the Hex file, the data address in the Hex file is verified and rewritten to determine that the Hex file can be recognized and read by the FLASH. Therefore, the user issues a user command on the preset interface of the electronic device, indicating the storage location of the file to be processed. The electronic device responds to the user command on the preset interface, reads the file to be processed according to the storage location indicated by the user command, or obtains the file path of the file to be processed according to the pre-running program code and reads the file to be processed.
[0060] 202. Perform data parsing processing on the file to be processed to determine each data segment in the file to be processed; wherein, the file to be processed includes N data segments, where N is a positive integer greater than zero, and each data segment includes vehicle execution data and data address.
[0061] In one example, the data address includes the starting extended address of the corresponding vehicle execution data and the starting extended linear address of the corresponding vehicle execution data.
[0062] For example, the electronic device reads the file to be processed, i.e. the Hex file to be processed, and performs data parsing processing on the file to be processed. For example, based on the pre-running program code, it parses and determines N data segments in the file to be processed, where N is a positive integer greater than zero. Each data segment includes vehicle execution data and the data address corresponding to the vehicle execution data. The vehicle execution data can be the program and data required for the vehicle MCU to run. The data address includes the starting extended address of the corresponding vehicle execution data and the starting extended linear address of the corresponding vehicle execution data.
[0063] 203. Determine the starting address of the corresponding data segment based on the starting extended address and the starting extended linear address in each data segment.
[0064] For example, the starting address of the corresponding data segment is determined based on the starting extended address and the starting extended linear address in each data segment. For instance, the starting extended address and the starting extended linear address are added together to obtain the starting address of the corresponding data segment.
[0065] 204. If the starting address of the data does not meet the preset address recognition conditions, then the data segment is determined as the target data segment. The preset address recognition conditions are used to determine whether the data address can be recognized by the preset storage device.
[0066] For example, if it is determined that the calculated starting address of the data does not meet the preset address recognition conditions, that is, it cannot be recognized by the preset storage device, for example, 0x8030010C cannot be divided by 32, cannot be read or written by FLASH, then the address is considered to be unaligned, and the data segment corresponding to the starting address of the data is determined to be the target data segment.
[0067] In one example, the hex file in this application no longer has the case of non-contiguous addresses. It only handles the case of address misalignment and only performs the minimum necessary padding. It does not perform any padding between the data segments.
[0068] 205. Based on the preset processing logic, perform data modification processing on the starting extended linear address of the target data segment to generate the corresponding data alignment address of the target data segment.
[0069] For example, based on preset processing logic, such as data processing logic included in a pre-written code program, the starting extended linear address of the target data segment is processed to generate the corresponding data alignment address of the target data segment.
[0070] In one example, when the preset storage device can recognize 32-bit address bytes, the processing logic for generating the data-aligned address of the target data segment can be represented as follows:
[0071] Data alignment address = (data start address / 0x20) * 0x20
[0072] In this context, 0x20 in hexadecimal is equivalent to 32 in decimal. (starting address of data / 0x20) * 0x20 means that the starting address of data is first divided by 0x20 to obtain the corresponding quotient value. The integer part of the quotient value is retained, and then the integer part of the quotient value is multiplied by 0x20 to obtain the data alignment address.
[0073] 206. Based on the data alignment address, perform data position shifting processing on the vehicle data of the corresponding target data segment to generate the updated target data segment.
[0074] In one example, the data segment also includes data length information for the vehicle execution data; the data segment also includes verification information for the corresponding vehicle execution data; step 206 includes the following steps:
[0075] Based on the data alignment address and data start address of the target data segment, determine the position offset of the corresponding vehicle execution data; based on the position offset and the data length information corresponding to the vehicle execution data, perform position shifting processing on the vehicle execution data; based on the data alignment address and the vehicle execution data after position shifting processing, regenerate and replace the verification information of the corresponding target data segment; based on the position offset, perform data filling processing on the corresponding target data segment to generate the updated target data segment.
[0076] For example, since the data address has changed, the vehicle execution data corresponding to the data address of the target data segment must also be moved along with the changed data address. This allows storage devices, such as FLASH, to accurately read the corresponding vehicle execution data based on the changed data address. After the vehicle execution data movement is completed, an updated target data segment is generated. The vehicle execution data of the corresponding target data segment is moved according to the data alignment address. For example, based on the obtained data alignment address of the target data segment and the previous data start address, the position offset of the corresponding vehicle execution data is determined. Then, based on the position offset and the data length information corresponding to the vehicle execution data, the vehicle execution data is moved. Furthermore, based on the data alignment address and the moved vehicle execution data, the verification information of the corresponding target data segment is regenerated and replaced; data filling is performed on the corresponding target data segment based on the position offset to generate an updated target data segment.
[0077] In one example, the total data length (LEN) of the vehicle execution data in the target data segment is obtained by summing the data lengths of each vehicle execution data recorded in the target data segment. Corresponding memory space is then allocated for the target data segment. Based on the calculated position offset, the vehicle execution data in each record of this segment is placed at the corresponding position, and the gap between the original address and the new address (i.e., the data start address and the data alignment address) is padded with 0xFF. No padding is applied to any new record data less than 32 bytes. Then, a new checksum (CheckSum) is recalculated for each record based on the rearranged vehicle execution data.
[0078] 207. Based on the updated target data segment and the data segment whose starting address meets the preset address recognition conditions, update the file to be processed and generate the target file corresponding to the file to be processed.
[0079] For example, after the target data is updated, the file to be processed also changes. Therefore, based on the updated target data segments, the file to be processed is updated. For example, based on the new extended address, new extended linear address, new record data length in each segment, vehicle execution data, and checksum, the Hex file is updated. Then, combined with data segments whose data start address meets the preset address recognition conditions, the target file is generated.
[0080] 208. In response to a user's trigger command on a preset interface, display the target file; wherein the trigger command is used to instruct the display of the target file.
[0081] For example, after the Hex file processing is completed and the target file is generated, the electronic device can output a prompt message indicating that the processing is complete, and display the target file in response to a user's trigger command on a preset interface.
[0082] In summary, the vehicle data processing method provided in this embodiment, based on a preset interface, responds to user commands and performs file reading, processing, and display, improving the operability and controllability of the processing process and optimizing the user experience. By determining the data start address of the corresponding data segment based on the start extended address and start extended linear address in each data segment, and then performing data modification processing on the start extended linear address of the target data segment based on preset processing logic, a corresponding data alignment address of the target data segment is generated. Based on the data alignment address, the vehicle execution data of the corresponding target data segment is processed by moving the data position, updating and replacing the verification information of the target data segment, and filling the gaps in the target data segment to generate an updated target data segment. This process achieves accurate batch verification processing of Hex files, improving the accuracy and efficiency of Hex file rewriting.
