DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] It should be understood that when used in this specification and the appended claims, the terms "include" and "comprises" indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0026] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0027] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0028] See also Figure 1 , Figure 1 A schematic flow chart of a firmware wireless upgrade method provided in an embodiment of the present invention. The method is mainly used in the control terminal of the vehicle-mounted device. Specifically, the firmware that needs to be updated in the vehicle-mounted device includes the main chip system firmware, the C-V2X module firmware and the 5G module firmware. The main chip system version is tightly bound to the C-V2X system version. If the versions do not match, it will cause functional abnormalities, while the 5G module firmware has no strong dependencies and can be updated with the firmware version as needed.

[0029] The main chip system adopts A / B partition structure, which can refresh the firmware and import the user-defined configuration backup to another partition without affecting the system operation, and mount another partition when restarting to achieve firmware update. The packaging and transmission of firmware can be achieved by combining the integrated tool swupdate with the device's own WiFi wireless network.

[0030] The firmware update of the C-V2X module and the 5G module is limited by the update method and can only be transmitted through the interface bus with the main chip, so it cannot be refreshed at the same time as the main chip. In the early stage of firmware transmission, the firmware of the two modules needs to be imported into the corresponding backup path of the current partition. After the backup partition updates the image, before restarting the system, the communication bus interface of the currently mounted partition is used in combination with the systemd service function of the main chip system to obtain and compare the firmware versions of the two modules to determine whether they need to be updated and mark them. After completing these tasks, the upgrade program will enter the restart process.

[0031] The A / B partition design effectively prevents errors or interruptions during the main system firmware upgrade process that may cause system crashes. At the same time, when updating module firmware, related functions inevitably need to be temporarily suspended. The systemd service functions involved in the module firmware upgrade can be temporarily shut down, and the system can be restarted after the firmware update is completed to automatically restore the normal startup of the functional services.

[0032] The method of this embodiment implements upgrading the firmware of the vehicle-mounted device by wireless upgrading, thereby improving the reliability of the system and optimizing the user experience during the upgrading process.

[0033] Figure 1 FIG. 1 is a flow chart of a firmware wireless upgrade method provided by an embodiment of the present invention. Figure 1 As shown, the method includes the following steps S110 to S130.

[0034] S110. Connect to the system WiFi hotspot, use the browser to upload the .swu firmware package, start the background upgrade program, confirm the version and configure the backup partition, and modify the bootloader variables to perform wireless upgrade of the main system.

[0035] In one embodiment, see Figure 2 The above-mentioned step S110 may include steps S111~S117.

[0036] S111. When the device is started, the upgrade service runs in the background, and the external device is connected to the system WiFi hotspot, use the browser to open the specified IP: port; S112, insert the firmware upgrade package with the .swu suffix into the web page, and trigger the system background upgrade program; S113, judging whether the specific variable identifier of the running program is preinst, so as to determine the main system version; S114, when the main system version is confirmed, obtain the module firmware version; S115, obtaining current partition and backup partition information and transmitting parameters; S116, formatting the backup partition; S117. Transfer and place the firmware in the .swu suffix file according to the sw-description file configuration, and modify the bootloder variable.

[0037] For the above steps S111 to S117, the main system adopts an A / B partition architecture, where the two partitions store the kernel and the root file system respectively. The key to this architecture is: Partition A: The currently running partition, providing a stable system environment.

[0038] B partition: backup partition, used when upgrading the system.

[0039] At startup, the bootloader will load the currently running partition to ensure that the system works properly. When upgrading the system, the currently running partition remains unchanged, while the backup partition is reformatted and updated with data. This mechanism ensures high availability and flexibility of the system. The loading process of partition A and partition B is as follows Fig.12 and Fig.13 shown.

[0040] The upgrade details include: Startup and partition mounting: When the bootloader boots the system, it mounts the currently running partition (for example, A), loads its kernel and file system, and ensures the normal operation of the system.

[0041] Upgrade: When a system upgrade is required, keep the current partition running (A) while formatting and updating the data in another partition (B).

[0042] After the data update is complete, the bootloader variables are set to notify that the new image has been successfully installed.

[0043] Restart and switch partitions: When you restart the device, the bootloader will boot to the updated partition (B) to ensure that the latest firmware and system are used.

[0044] Fault recovery mechanism: If the backup partition data fails to update or the upgrade is interrupted, the bootloader will not modify the boot program variables. At this time, the system will still run on the currently mounted partition (A), avoiding system unavailability due to upgrade failure.

[0045] The upgrade tool includes: swupdate tool: This upgrade is mainly implemented using the swupdate tool, which has powerful configuration and customization capabilities.

[0046] In the sw-description file, define the software and hardware versions, partition configuration, firmware package transfer path, and execution script (such as manualop.sh).

[0047] Web page trigger upgrade: When the external device is connected to the main device via WiFi and accesses the specific IP and port, it can enter the upgrade web page.

[0048] The user uploads the firmware upgrade package with the .swu suffix on the web page to trigger the swupdate program.

[0049] The upgrade process nodes include: System version confirmation: Verify the compatibility of the current system version and firmware.

[0050] Firmware package transfer: Transfer the firmware package to the device via the network.

[0051] Execute the manualop.sh script to perform necessary system settings or file operations.

[0052] Modify identification parameters: Update system status and version identification.

[0053] Reboot System: Reboot the device after the upgrade is complete to apply the new firmware.

[0054] The main system upgrade step of this embodiment adopts the A / B partition architecture to ensure that the system is still available even if a failure occurs during the upgrade process, avoiding the risk of system crash. Firmware upload and upgrade through the web page simplifies user operations and improves user experience. The current running partition is not modified during the upgrade process, and a rollback mechanism is provided to ensure system security and reliability. The automated process of system version confirmation and script execution reduces manual intervention and improves maintenance efficiency. By configuring the file transfer size limit, it is possible to flexibly respond to the upgrade requirements of large files and avoid upgrade failures.

[0055] In summary, the A / B partition upgrade process combined with the swupdate tool provides a high-availability, secure, and convenient system upgrade solution.

[0056] S120. Restore the user-defined configuration.

[0057] In this embodiment, it is determined that the running program specific variable identifier is postinst to determine that the main system software update is completed, and the user-defined configuration is centrally backed up and restored.

[0058] Specifically, when the parameter of the user-defined configuration is postinst, the user-defined configuration is stored centrally, and during the upgrade, a mount point is created, the root partition is determined, and related configurations are restored. The related configurations include WiFi, Bluetooth, Ethernet, 5G, CAN configurations, and app applications added by the user.

[0059] The entire restore includes backup and recovery, as follows: Detect the current root partition: When the script starts, check / proc / cmdline to determine whether the current root partition (curroot) is / dev / mmcblk0p2 or / dev / mmcblk0p4. Set the backup partition (slotB) based on the current root partition.

[0060] Mount the backup partition: Use the mount command to mount the backup partition to / mnt / slotB for subsequent operations.

[0061] Back up WiFi configuration: Check whether the / etc / wifi directory exists. If so, do the following: Clear the WiFi configuration content in the current backup partition ( / mnt / slotB / etc / wifi).

[0062] Copy the WiFi configuration of the current partition ( / etc / wifi) to the backup partition.

[0063] Continue to back up other configuration items: The backup process can be expanded to include other user-defined configuration items such as Bluetooth, Ethernet, CAN, 5G, etc.

[0064] Complete backup: After completing the backup of all configuration items, ensure data integrity and consistency and improve system reliability.

[0065] This step centrally manages user-defined configuration items, making it easier for technical support staff to maintain and update them, thus improving work efficiency. Users do not need to manually back up and restore configuration items, as automated system processing reduces human errors. When the system is upgraded, configuration items can be quickly restored, reducing the risk of the upgrade and ensuring that the system runs normally under the new firmware. By cleaning up old configurations and backing up current configurations, data security is ensured to avoid configuration conflicts and loss. Users can quickly switch configurations based on their needs, which improves the flexibility and customizability of the system and adapts to different usage scenarios.

[0066] In summary, automated backup and recovery steps not only improve the system maintainability and user experience, but also ensure system stability and data security during the upgrade process.

[0067] S130: Determine the firmware update requirements for the C-V2X module and the 5G module, and perform corresponding flashing and restart operations respectively to ensure that the device is restarted after the update is successful.

[0068] In one embodiment, see Figure 3 The above-mentioned step S130 may include steps S131~S135.

[0069] S131. Determine whether the C-V2X module firmware needs to be updated; S132. If the C-V2X module firmware does not need to be updated, determine whether the 5G module firmware needs to be updated; S133. If the 5G module firmware does not need to be updated, restart the device.

[0070] In this embodiment, to determine whether the module firmware needs to be updated, whether it is the C-V2X module firmware or the 5G module firmware, the current firmware version information of the C-V2X and 5G modules can be obtained using relevant commands or API interfaces. Get the latest firmware version information from the backup partition. This usually involves querying a version control file or API. Compare the current firmware version with the latest firmware version. The following methods can be used: Version number comparison: If the current version number is lower than the latest version number, you need to update it.

[0071] Feature comparison: If the new version has new features or fixes known issues in the current version, it can also be determined that an update is needed.

[0072] Other factors may also be considered, such as: Security: If the new version fixes a security vulnerability, then you should update. Compatibility: If the new version is incompatible with other parts of your device, then you may also need to update.

[0073] Based on the comparison result, the following logic is executed: The module firmware version is bound to the entire system version. If the versions do not match, the realization of the module functions may be affected. Therefore, the update logic is to determine whether it is consistent with the module firmware version in the upgrade package. If it is inconsistent, it will be refreshed. This involves the situation of downgrading the version. If the old system version is flashed, the module firmware will also be downgraded to the firmware version corresponding to the corresponding system version to adapt. However, the module firmware update frequency is not high, and sometimes several system versions are bound to the same module firmware version.

[0074] S134. If the C-V2X module firmware needs to be updated, when the C-V2X module firmware is 2k hardware, 2k firmware is flashed; when the C-V2X module firmware is not 2k hardware, 4k firmware is flashed.

[0075] In one embodiment, see Figure 4The above-mentioned step S134 may include steps S1341~S1346.

[0076] S1341. Stop services related to the C-V2X module firmware.

[0077] In this embodiment, the systemctl command is used to stop services related to the C-V2X firmware.

[0078] Stopping the service during the update process can avoid data conflicts and inconsistencies, ensuring the security of the firmware update.

[0079] S1342. Mount the backup partition and copy the C-V2X module firmware from the backup partition to the specified path of the current partition.

[0080] In this embodiment, the backup partition is mounted to the specified path of the current partition to obtain the C-V2X firmware.

[0081] Ensure you have the latest and complete firmware package by accessing the backup partition.

[0082] S1343. Decompress the copied C-V2X module firmware.

[0083] In this embodiment, the firmware package is copied from the backup partition to the upgrade path of the current partition, which simplifies the firmware access path and facilitates subsequent operations.

[0084] Unzip the firmware package to prepare for flashing. After unzipping, you can directly access the firmware file to ensure that you are using the correct file when flashing.

[0085] S1344. Obtain the C-V2X module firmware hardware information, determine the upgrade package to be used based on whether the hardware information belongs to 2k hardware or 4k hardware, and enter the specified path of the current partition.

[0086] In this embodiment, the hardware information of the module is obtained through the adb command to determine the upgrade package to be used.

[0087] Make sure to only flash firmware that is compatible with your hardware to avoid potential damage.

[0088] S1345. Restart the C-V2X module firmware and enter fastboot mode; In this embodiment, the adb command is used to enter the fastboot mode to prepare for flashing the firmware.

[0089] Fastboot mode provides a safe and efficient flashing environment.

[0090] S1346. Clear and rewrite the C-V2X module firmware in fastboot mode, and confirm the version after the update is complete.

[0091] In this embodiment, a series of fastboot commands are used to perform firmware clearing and flashing operations.

[0092] By erasing and flashing firmware partitions one by one, you can ensure that every part of the system is updated without missing any.

[0093] After the flashing is complete, restart the module and confirm the C-V2X firmware version through commands.

[0094] Ensures successful firmware updates and can detect issues quickly.

[0095] S135, restarting the C-V2X module after flashing the C-V2X module firmware, and executing step S132; S136. If the 5G module firmware needs to be updated, flash the 5G firmware, restart the 5G module firmware, and execute step S133.

[0096] In one embodiment, see Figure 5 The above-mentioned step S135 may include steps S1361~S1365.

[0097] S1361. Stop services related to 5G module firmware.

[0098] In this embodiment, the systemctl command is also used to stop services related to the 5G module.

[0099] Prevents the operation of 5G services from interfering with firmware updates and ensures data integrity.

[0100] S1362. Copy the 5G module firmware from the backup partition to the specified path of the current partition.

[0101] In this embodiment, the backup partition is mounted to a specified path to obtain the 5G module firmware package, ensuring that the latest 5G firmware is obtained.

[0102] S1363. Decompress the copied 5G module firmware.

[0103] In this embodiment, the 5G module firmware package in the backup partition is copied to the current partition.

[0104] The file access process is simplified to facilitate subsequent operations.

[0105] Unzip the firmware package to prepare for subsequent upgrade operations.

[0106] After decompression, you can directly access the firmware to ensure smooth subsequent operations.

[0107] S1364. Use the system's own qdl tool and the XML file in the firmware package to upgrade the 5G module firmware.

[0108] In this embodiment, the 5G firmware is upgraded using the system's built-in qdl tool and the xml file in the firmware package.

[0109] The qdl tool provides an efficient and reliable way to perform firmware upgrades, simplifying operations.

[0110] S1365. Restart the 5G module firmware after the upgrade is complete, and confirm the version after the update is complete.

[0111] In this embodiment, the module is restarted after the upgrade is completed, and it is confirmed that the communication channel connected to the 5G module is initialized normally.

[0112] Ensure that the 5G module works normally and detect and solve possible problems in time.

[0113] The method of this embodiment facilitates the upgrade process of embedded devices based on the Linux operating system in multiple firmware systems. By simplifying the operation steps, such as driver installation, device disassembly, DIP switch adjustment, hardware interface confirmation and cable connection, it can effectively reduce maintenance time and significantly reduce the difficulty and error probability of upgrading multiple firmware at the same time. This method not only provides convenience for technical support personnel, but also allows the solution to be quickly synchronized to the customer's device after the problem is solved, thereby reducing equipment maintenance and labor costs.

[0114] At the same time, the use of WiFi encrypted connection can prevent unauthorized personnel from logging in, and the specific format of the upgrade firmware package and the setting of A / B partitions can avoid upgrade failures and system crashes caused by incorrect firmware package transmission. Therefore, no matter what type of vehicle-mounted equipment, wireless upgrade has become a trend and an essential basic function of vehicle-mounted equipment.

[0115] The above firmware wireless upgrade method allows users to upload the .swu firmware package in the browser and start the background upgrade program by connecting to the system's WiFi hotspot. The system will confirm the version and configure the backup partition, and modify the bootloader variables to achieve wireless upgrade of the main system. After the main system upgrade is completed, the user-defined configuration will be restored. Next, determine the firmware update requirements of the C-V2X module and 5G module, and perform flash and restart operations respectively. Finally, ensure that the update is successful before restarting the device to improve system reliability and optimize user experience.

[0116] Figure 6 is a schematic block diagram of a firmware wireless upgrade device 300 provided in an embodiment of the present invention. Figure 6As shown, corresponding to the above firmware wireless upgrade method, the present invention also provides a firmware wireless upgrade device 300. The firmware wireless upgrade device 300 includes a unit for executing the above firmware wireless upgrade method, and the device can be configured in a vehicle-mounted device. Figure 6 The wireless firmware upgrade device 300 includes a main system upgrade unit 301 , a restoration unit 302 and a firmware update unit 303 .

[0117] The main system upgrade unit 301 is used to connect to the system WiFi hotspot, upload the .swu firmware package using a browser, start the background upgrade program, confirm the version and configure the backup partition, and modify the bootloader variables to perform wireless upgrades of the main system; the restore unit 302 is used to restore the user-defined configuration; the firmware update unit 303 is used to determine the firmware update requirements of the C-V2X module and 5G module, and perform corresponding flashing and restart operations respectively to ensure that the device is restarted after the update is successful.
