It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present disclosure, but the present disclosure can also be implemented in other manners different from those described herein; obviously, the embodiments described in the specification are only a part of the embodiments of the present disclosure, and not all the embodiments.

[0026] To solve the problems in the prior art, the present application provides a vehicle machine flashing method, device, equipment, medium and product.

[0027] The vehicle machine flashing method provided by the embodiments of the present application is introduced below.

[0028] Figure 1 The flowchart of the vehicle machine flashing method provided by an embodiment of the present application is shown. As shown in the figure, Figure 1 The method can specifically include the following steps:

[0029] Step 101, in the case that the official version software flashing of the vehicle machine fails and the vehicle machine has debugging permission, the working state of the vehicle machine is switched to a flashing mode by calling a first mode switching instruction;

[0030] Step 102, in the flashing mode, the debugging version software is flashed into the vehicle machine;

[0031] Step 103, in the case that the flashing of the debugging version software succeeds, the official version software is flashed into the vehicle machine.

[0032] In step 101, in the case that the official version software of the car machine fails to be written and the car machine has a debugging permission, the working state of the car machine is switched to a writing mode by calling a first mode switching instruction.

[0033] In the embodiment, the execution subject is a writing bench, and the writing processes are all performed on the writing bench. The writing bench comprises an upper computer. The upper computer controls the car machine to complete the writing by sending a control instruction.

[0034] Since after the official version of the car machine fails to be written, if the official version of the car machine is to be written again, the debugging software version needs to be written before the official version is written again, so that the official software version can be written again. Therefore, in the embodiment, the working state of the car machine is switched to the writing mode, and the debugging version software is written in the writing mode.

[0035] The writing mode can be a fastboot mode. The fastboot mode is a flashing mode of an Android device, and is mainly used for writing the debugging version software into the car machine through the USB data line on the upper computer. The debugging permission can be an Android debugging bridge (ADB) permission, which is used to obtain the flashing permission of the car machine. The mode switching instruction can be adb reboot bootloader. The mode switching instruction is an instruction corresponding to the debugging permission, and is used to switch the working state of the car machine to the fastboot mode.

[0036] It should be noted that before the mode switching instruction is called, the ADB reboot control instruction is run on the writing bench through the CMD command line to control the car machine to be powered on and powered off again, and then the mode switching instruction is called. The CMD is a Windows command prompt. The CMD is a command line operation tool of the Windows system. The user can complete the power-on and power-off of the car machine by inputting ADB reboot.

[0037] In step 102, the debugging version software is written into the car machine in the writing mode.

[0038] It should be noted that the car machine includes three modules, which are a control module, a network module and an operation module, wherein the operation module can be a system on chip (SOC), the SOC can be an Android system, which is an operating system directly interacting with users for the car machine, and carries system applications and multimedia applications of the upper layer. The control module can be a microcontroller unit (MCU): used to be responsible for the basic calculation and control of the SOC. The network module can be a 5G module, used to be responsible for the 5G networking module of the whole vehicle, mainly providing traffic online services and the like for the car machine.

[0039] The above-mentioned debugging version software includes an operation software package corresponding to the SOC, and a network software package corresponding to the 5G module. In the process of flashing the debugging version software, the operation software package needs to be flashed into the operation module, and the network software package needs to be flashed into the network module.

[0040] In step 103, in the case that the debugging version software is successfully flashed, the formal version software is flashed into the car machine.

[0041] In the embodiment, the judgment step that the debugging version software is successfully flashed includes:

[0042] Firstly, the bench obtains the network connection states of the control module, the network module and the operation module through the ping command in the CMD command line; secondly, the bench reads the software package versions in the control module, the network module and the operation module through adb; in the case that the network connection states of the control module, the network module and the operation module are all connected, and the software package versions in the network module and the operation module are the same as the debugging version software, the debugging version software is successfully flashed.

[0043] In an example, if the IP address of the control module is 172.31.2.53, the IP address of the network module is 172.31.2.54, and the IP address of the operation module is 172.31.2.51, firstly, ping 172.31.2.51, ping 172.31.2.53, and ping 172.31.2.54 can all get a reply, so the network connection state is considered to be connected. Secondly, the bench can read the software versions of the corresponding SOC, MCU and 5G through adb, that is, it is judged to be successfully flashed.

[0044] After the debugging version software is successfully flashed, the flashing bench reads the formal version software stored in the host computer and flashes the formal version software into the car machine.

[0045] In the embodiment, in the case that the vehicle machine fails to write the formal version software and has the debugging permission, the working state of the vehicle machine can be automatically switched to the writing mode, and the debugging version software is written into the vehicle machine in the writing mode, so as to prepare for writing the formal version software of the vehicle machine again, and the second writing can be performed immediately after the vehicle machine fails to write, so that the problem of manually operating the vehicle machine and isolating the vehicle machine can be avoided, the automatic writing of the vehicle machine can be realized, the problem of wasting human resources caused by manual writing can be reduced, and the writing efficiency is improved.

[0046] In an embodiment of the present application, the writing of the debugging version software into the vehicle machine comprises:

[0047] controlling the vehicle machine to run the writing script corresponding to the operation software package in the debugging version software, so as to write the operation software package into the vehicle machine;

[0048] in the case that the operation software package is completed, calling the writing instruction corresponding to the debugging permission to write the network software package into the vehicle machine.

[0049] In the embodiment, when the debugging version software is written, the operation software package and the network software package need to be written into the vehicle machine, so that in the case that the operation software package is written, the writing script corresponding to the operation software package can be set in the debugging version software, and after the script is run, the operation software package can be directly written into the operation module in the vehicle machine. Specifically, the script can be a fastboot_all_and_erase_all.bat script.

[0050] After the writing of the operation software package is completed, the writing of the network software package is performed, and the network software package can be written by calling the writing instruction, wherein the writing instruction comprises an import instruction, a permission instruction, a writing instruction and an exit instruction.

[0051] In an embodiment, the calling of the writing instruction corresponding to the debugging permission to write the network software package into the vehicle machine comprises:

[0052] the calling of the opening instruction controls the vehicle machine to open the root permission;

[0053] the calling of the import instruction imports the network software package into the network module in the vehicle machine;

[0054] the calling of the permission instruction enables the network module to enter the open permission mode;

[0055] the calling of the writing instruction writes the network software package into the network module;

[0056] The exit instruction is called to make the network module exit the open permission mode.

[0057] In the embodiment, the start instruction, the import instruction, the permission instruction, the write instruction and the exit instruction are all instructions corresponding to the debugging permission, that is, only under the debugging permission, the above instructions can be run.

[0058] In an example, the start instruction can be adb root, that is, to start the root permission of the vehicle machine, wherein under the root permission, the writing bench can have the highest permission of the vehicle machine, at this time, the writing bench can perform all operations of adding, deleting, modifying and inquiring any file (including system file) in the vehicle machine. Under the root permission, the subsequent steps can be performed.

[0059] The import instruction can be adb push 5G software package / data / modefm / 5G, that is, to import the 5G software package to the 5G module.

[0060] The permission instruction can be adb shell vehicle_tool-s SOC_MCU_5GEDL_SET:69, that is, to switch the 5G module of the vehicle machine to the edl mode, and lsusb is used to check whether the vehicle machine enters the 9008 mode, wherein the edl mode of the 5G module corresponds to the 9008 mode of the vehicle machine, and both are used to make the network module enter the open permission mode, wherein the open permission module is that the network module opens the control permission of itself to the writing bench, so that the writing bench can write the network software package to the network module.

[0061] The write instruction can be QFirehose-f / data / modemfw / 5G-n, which is used to write the 5G software package to the network module.

[0062] The exit instruction can be vehicle_tool-s SOC_MCU_5GEDL_SET:67, which is used to control the 5G module to exit the edl mode, that is, the open permission mode, after the 5G software package is written.

[0063] In the embodiment, the writing bench is used to call the writing instruction to write the debugging version software to the vehicle machine, so that the automatic writing of the writing bench is realized, manual operation is not needed, the labor cost is reduced, and the writing efficiency is improved.

[0064] In an embodiment of the present application, when the writing of the formal version software of the vehicle machine fails and the vehicle machine has a debugging permission, a first mode switching instruction is called to switch the working state of the vehicle machine to a writing mode, which includes:

[0065] In a case where the official version software of the car machine fails to be written, and the car machine has a debugging permission, a first restart instruction corresponding to the debugging permission is called to control the car machine to restart;

[0066] In a case where the car machine completes the restart, a first mode switching instruction is called to switch the working state of the car machine to a writing mode.

[0067] In the embodiment, the first restart instruction can be adb reboot. In a case where the car machine has the debugging permission, to ensure that the debugging version software can be successfully written, the car machine needs to be controlled to restart and the writing mode of the car machine needs to be opened.

[0068] In an embodiment of the present application, before the debugging version software is written into the car machine in the writing mode, the method further comprises:

[0069] In a case where the official version software of the car machine fails to be written, and the car machine does not have a debugging permission, a preset writing tool is connected with the car machine in response to a received connection instruction, so that the car machine opens the debugging permission through the writing tool;

[0070] A second mode switching instruction is called to switch the working state of the car machine to a writing mode.

[0071] In the embodiment, the connection instruction can be manually sent or automatically triggered by a writing rack in a case where it is detected that the car machine does not have the debugging permission. The writing tool is connected with the car machine, so that the car machine has the ADB permission, and the writing of the debugging version software can be performed.

[0072] The second mode switching instruction can be mdb-fastboot_hu_f, so that the car machine enters the fastboot mode. Then, the writing rack writes the debugging version software into the car machine.

[0073] In the embodiment, in a case where the car machine does not have the debugging permission, the car machine is connected with the writing tool, so that the car machine has the debugging permission, and the writing of the debugging version software of the car machine is completed. The success rate of the car machine in writing the debugging version software is improved, so that the success rate of the official version software is improved.

[0074] In an embodiment of the present application, after the official version software is written into the car machine in a case where the writing of the debugging version software is successful, the method further comprises:

[0075] send a first detection instruction to a control module, a network module and an operation module in the car machine respectively, the control module is used for writing a control software package in the official version software, the network module is used for writing a network software package in the official version software, and the operation module is used for writing an operation software package in the official version software;

[0076] acquire a to-be-tested control software package version in the control module, a to-be-tested network software package version in the network module and a to-be-tested operation software package version in the operation module;

[0077] in the case of satisfying a first preset condition, it is determined that the official version software is successfully written:

[0078] the first preset condition comprises:

[0079] information fed back by the control module, the network module and the operation module based on the first detection instruction is received;

[0080] the to-be-tested control software package version, the to-be-tested network software package version and the to-be-tested operation software package version are the same as the official version software.

[0081] In the embodiment, after the official version software is written into the car machine, the writing result is needed to judge whether the official version software needs to be re-written, so that whether the official version software is successfully written can be determined by acquiring the network connection state of each module in the car machine and the to-be-tested version software existing in the car machine.

[0082] Specifically, the first detection instruction is a ping instruction, and the network connection state of each module in the car machine is acquired by pinging the IP address of each module in the car machine. Whether the network connection state is connected or not is used as one of the conditions for determining whether the car machine is successfully written. The to-be-tested software version includes a to-be-tested control software package version, a to-be-tested network software package version and a to-be-tested operation software package version, and whether the to-be-tested version software and the version of each software package in the official version software are the same is used as one of the conditions for determining whether the writing is successful.

[0083] When the IP address of each module in the car machine is pinged, if each module in the car machine replies, it is considered that the network connection of each module is normal. In the case that the network connection of each module is normal, if the to-be-tested control software package version is the same as the software package version in the official version software, the to-be-tested network software package version is the same as the network software package version in the official version software, and the to-be-tested operation software package version is the same as the operation software package version in the official version software, it is considered that the official version software is successfully written.

[0084] It should be noted that when the judgment of the writing result of the formal version software is performed, the network connection state of the control module, the network module and the operation module and the version of the software package need to be acquired, and when the judgment of the writing result of the debugging version software is performed, only the network connection state of the network module and the operation module and the version of the software package need to be acquired.

[0085] In the embodiment, after the formal version software is re-written in the car machine, whether the formal version software is successfully written is judged by acquiring the connection state of each module in the car machine and the version of the software package, so that the writing of the car machine is ensured to be successful, the misjudgment is reduced, and the working efficiency of the writing is improved.

[0086] In an embodiment of the present application, the writing of the formal version software into the car machine in the case that the writing of the debugging version software is successful comprises:

[0087] A second restart instruction corresponding to the debugging permission is called to control the car machine to restart;

[0088] In the case that the car machine completes the restart, the formal version software is written into the car machine.

[0089] In the embodiment, the second restart instruction can be adb reboot. After the writing of the debugging version software is completed in the car machine, the car machine needs to be restarted to ensure that the formal version software can be successfully written.

[0090] After the restart of the car machine is completed, the network software package of the formal version software is written into the network module of the car machine, the operation software package of the formal version software is written into the operation module of the car machine, and the control software package of the formal version software is written into the control module of the car machine.

[0091] Here, it should be noted that, unlike the writing of the debugging version software, when the writing of the debugging version software is performed in the case that the writing of the formal version software fails, only the operation software package and the network software package need to be written into the car machine, and the control software package does not need to be written.

[0092] In the embodiment, during the writing of the formal version software, the writing success rate of the car machine is improved by controlling the car machine to restart and writing the software package in each module in the car machine, and the writing of the car machine is ensured to be completed normally.

[0093] In an embodiment of the present application, whether the writing of the debugging version software is successful is determined by the following steps:

[0094] sending a second detection instruction to a control module, a network module and an operation module in the car machine respectively, the control module being configured to write the control software package in the debugging version software, the network module being configured to write the network software package in the debugging version software, and the operation module being configured to write the operation software package in the debugging version software;

[0095] obtaining a to-be-tested control software package version in the control module, a to-be-tested network software package version in the network module and a to-be-tested operation software package version in the operation module;

[0096] in a case where a second preset condition is met, determining that the debugging version software is successfully written;

[0097] the second preset condition comprises:

[0098] receiving information fed back by the control module, the network module and the operation module based on the second detection instruction;

[0099] the to-be-tested control software package version, the to-be-tested network software package version and the to-be-tested operation software package version are the same as the debugging version software.

[0100] In the embodiment, the second detection instruction is the same as the first detection instruction, and the condition for determining that the debugging version software is successfully written is the same as the condition for determining that the formal version software is successfully written, which will not be described herein.

[0101] Figure 2 Fig. 1 shows a schematic diagram of the overall flow of the car machine writing method in an embodiment of the present application.
