Description

TECHNICAL FIELD

[0001] The present application relates to the field of software tools, in particular to a firmware burning method, device and system of a split 5G / V2X device. BACKGROUND

[0002] The split 5G / V2X device is a fusion device of multiple devices, which includes at least three large components such as an application processor device end, a 5G module device end, and a C-V2X module device end. The application processor, the 5G module, and the C-V2X module are three core components of the split 5G / V2X device, which support the basic functions of the split 5G / V2X device: 5G and V2X. Each of the three components has its own dedicated software system firmware, so the overall firmware of the split 5G / V2X device includes independent application processor firmware, 5G module firmware, and C-V2X module firmware, and each firmware upgrade needs to be upgraded separately for the application processor, the 5G module, and the C-V2X module, as well as compatibility processing of different firmware versions between components. Specifically, the split 5G / V2X device provides three USB ports on the hardware level, which are used for application processor firmware burning, 5G module firmware burning, and C-V2X module firmware burning, respectively. Each firmware burning has its own burning tool and burning strategy, so this firmware burning method will inevitably cause at least two problems:

[0003] 1. Since the firmware of each component of the split 5G / V2X device exists independently, it is easy to cause firmware version management confusion, leading to incompatible firmware versions between components and causing function and system stability problems;

[0004] 2. The firmware of each component of the split 5G / V2X device needs to be burned separately, which greatly increases the operation difficulty and operation time of developers, testers, and factory production personnel, greatly reducing work efficiency. SUMMARY

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0049] In view of the technical problems of version management confusion of the firmware of each component and the need for separate burning of each firmware in the prior art, the present application proposes a new firmware burning scheme for split type 5G / V2X equipment. The scheme designs an integrated automatic firmware burning strategy for the application processor, 5G module and C-V2X module. Specifically, the firmware of the three components is stored and released centrally and uniformly. In addition to the driver of the firmware burning device end that must be installed, all other dependent tools are integrated into the firmware burning package. In addition, a batch processing program is designed, and the user can start the integrated automatic firmware burning operation by clicking the batch processing program.

[0050] Figure 1 is a flowchart of embodiment one of the firmware burning method of the split type 5G / V2X equipment of the present application, combined with Figure 2 The firmware burning method of this embodiment is applied to the firmware burning device 10, for example, a PC with a windows operating system, and the firmware burning device 10 is connected with the split type 5G / V2X equipment 20. The split type 5G / V2X equipment includes an application processor 21 and a 5G module 22 and a C-V2X module 23 connected with the application processor 21 respectively. In this embodiment, the firmware burning method of the split type 5G / V2X equipment includes:

[0051] The step S10 of creating an integrated firmware burning package, the integrated firmware burning package includes the firmware set of the application processor, the firmware package of the 5G module, the firmware of the C-V2X module, the device running tool and the firmware burning batch processing program arranged in the same directory;

[0052] In this step, all the firmware to be burned of the split type 5G / V2X equipment 20 and the burning dependent tools are integrated. Specifically, an integrated firmware burning package is created on the firmware burning device 10. The integrated firmware burning package includes the firmware set of the application processor 21, the firmware package of the 5G module 22, the firmware of the C-V2X module 23, the device running tool and the firmware burning batch processing program arranged in the same directory.

[0053] As to the device running tool, it contains command line programs running on the windows end for firmware burning, which include a command line program for burning the application processor firmware, a command line program for burning the C-V2X module firmware and a command line program for burning the 5G module firmware.

[0054] As to the firmware burning batch program, its suffix name is usually bat or BAT, which is a script program for batch execution of commands on windows, similar to the bash script program on the Linux system. The above-mentioned command line programs for burning the firmware of the three components are organized according to specific rules and order to form a firmware burning batch program on windows (such as the name l10a-flash-all.bat), and the specific order is: first, burn the firmware of the application processor, then burn the firmware of the 5G module, and finally burn the firmware of the C-V2X module.

[0055] Triggering step S20: receiving a trigger signal input by a user;

[0056] In this step, the user can start the integrated automatic firmware burning operation by clicking the firmware burning batch program.

[0057] Executing step S30: starting the firmware burning batch program according to the trigger signal to burn the firmware of the application processor, the 5G module and the C-V2X module in turn through the device running tool.

[0058] In this step, combined with Figure 2 When the user triggers the firmware burning batch program, the power switch can be turned on to power the split 5G / V2X device through the power adapter, at this time, the firmware burning batch program (for example, l10a-flash-all.bat) starts to execute, that is, the firmware of the application processor, the firmware of the 5G module and the firmware of the C-V2X module are burned in turn and automatically.

[0059] The technical scheme of this embodiment integrates the independent system firmware of multiple different components together, so that the maintenance and management of the overall firmware of the software system of the split 5G / V2X device becomes simpler, and the compatibility problem between different firmware versions caused by the scattered management of the independent system firmware of different components is avoided, thus improving the software stability of the product and reducing the failure rate of the product. At the same time, by triggering the firmware burning batch program to automatically burn the firmware of the split 5G / V2X device in a certain order, the work efficiency of the software and hardware development and test personnel is greatly improved, and the production efficiency of the factory is greatly improved.

[0060] In one alternative embodiment, such as Figure 2 As shown, the firmware burning device 10 includes two USB ports, wherein the first USB port is used to connect to the application processor 21 via a first USB data cable, and the second USB port is used to connect to the C-V2X module 23 via a second USB data cable.

[0061] In addition, the device operating tools include: a command-line flashing tool for the application processor 21; a firmware configuration file for the application processor 21; and a command-line flashing tool for the C-V2X module 23. In a specific example, the application processor 21 is an i.MX series application processor from NXP, the 5G module 22 is a SIM8x series 5G module from SIMCOM based on the Qualcomm SDX55 chip, and the C-V2X module 23 is a UMV-9150LGA module from WNC (Taiwan) based on the Qualcomm MDM9150 chip. Furthermore, flashing the firmware for the i.MX series application processor 21 requires the command-line flashing tool uuu.exe, flashing the firmware for the 5G module 22 requires Qualcomm's command-line flashing tool qdl, and flashing the firmware for the C-V2X module 23 requires using the Android system's mode switching tool adb tools to switch to fastboot mode, and then using the fastboot command-line tool in this mode for flashing. Therefore, when creating the all-in-one firmware flashing package, firstly, all the software tools required for flashing the i.MX series application processor firmware are installed in the firmware directory, including: the adb / fastboot toolset; Python version 2.7 (which runs the Python scripts in the batch processing program, eliminating the need for users to install PC program suites); and the i.MX series application processor firmware flashing dedicated command-line tool uuu. Next, the firmware of the 5G module is packaged and compressed into a tar format file and copied to the firmware directory. Then, the firmware of the C-V2X module is directly copied to the firmware directory. Finally, the i.MX series application processor firmware configuration file emmc.uuu and the firmware flashing batch processing program 5gv2x-flash-all.bat are placed in the firmware directory, thus forming the all-in-one firmware flashing package.

[0062] In this embodiment, step S30 involves sequentially flashing firmware onto the application processor, the 5G module, and the C-V2X module using the device running tool, including:

[0063] Step S31. Using the command line burning tool of the application processor, the firmware of the application processor is burned through the first USB port, and then the firmware of the 5G module is burned by executing the corresponding command line burning tool in the application processor according to the firmware configuration file of the application processor.

[0064] Step S32. Using the command line burning tool of the C-V2X module, the firmware of the C-V2X module is burned through the second USB port.

[0065] In this embodiment, the firmware of the application processor is upgraded first, and then the firmware of the 5G module is burned by executing the corresponding command line burning tool (qdl) in the application processor after the firmware of the application processor is upgraded. Compared with the prior art which needs to connect the 5G module with the firmware burning device through a USB data line to burn the firmware of the 5G module, the firmware burning device of this embodiment can only be provided with two USB ports, and two USB data lines are used to connect the split type 5G / V2X device, that is, one USB data line is used to connect the application processor of the split type 5G / V2X device, and the other USB data line is used to connect the C-V2X module of the split type 5G / V2X device. Therefore, the split type 5G / V2X device can reduce one USB data line in the hardware operation layer.

[0066] Further, the firmware set of the application processor includes a U-BOOT image file, a kernel image file, a device tree image file, and a virtual memory file system; and the integrated firmware burning package further includes an IMEI number backup script. Moreover, step S31 includes:

[0067] The U-BOOT image file is downloaded to the memory of the application processor through the first USB port and started;

[0068] The kernel image file, the device tree image file, and the virtual memory file system are downloaded to the memory of the application processor through the first USB port, so that the application processor loads and starts the Linux kernel and enters the kernel fast start mode;

[0069] In the kernel fast start mode, the U-BOOT image file, the kernel image file, the device tree image file, and the virtual memory file system are written into the application processor;

[0070] In the kernel fast start mode, the firmware package of the 5G module and the IMEI number backup script are respectively downloaded to the cache of the application processor through the first USB port, and the IMEI number backup script is executed to backup the IMEI number before the firmware of the 5G module is burned, and the burning command corresponding to the 5G module is executed in the application processor.

[0071] After the 5G module restarts, the backed-up IMEI number is written back to the 5G module.

[0072] Further, step S32 includes:

[0073] switching the C-V2X module to a fast start mode through the second USB port;

[0074] In the fast start mode, the C-V2X module is subjected to firmware programming through the second USB port, and the C-V2X module is restarted.

[0075] After the C-V2X module is restarted, the updated firmware version number of the C-V2X module is read through the second USB port.

[0076] In one specific embodiment, a firmware configuration file (such as uuu.exeemmc.uuu) for an i.MX series application processor is used to provide a scheme for collectively programming NXP i.MX series application processor firmware and 5G module firmware. When the command uuu.exe for programming the NXP i.MX series application processor firmware is executed, the firmware configuration file needs to be used. Specifically, the command uuu.exe for programming the application processor firmware parses and extracts the instruction sequence written in the firmware configuration file emmc.uuu, executes the emmc.uuu configuration file, and the execution flowchart is as shown in Figure 3 The corresponding firmware configuration file emmc.uuu file content (# indicates a comment) is as follows:

[0139] In addition, imeibackup.tar is a packed file of the IMEI backup script, and the script program itself reads the IMEI number before the 5G module firmware is burned by AT instructions and saves it, thereby playing a role in backing up the IMEI number. The file in tar format is made to retain the executable permission of the IMEI backup script.
