[0023] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. 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, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0026] In order to solve the problems of the prior art, the embodiments of the present application provide a vehicle computer flashing method, device, equipment, medium and product.

[0027] The following is an introduction to the vehicle computer flashing method provided in the embodiment of the present application.

[0028] Figure 1 FIG. 1 is a flow chart of a vehicle computer flashing method provided by an embodiment of the present application. Figure 1 As shown, the method may specifically include the following steps:

[0029] Step 101, when the flashing of the official version software of the vehicle computer fails and the vehicle computer has debugging authority, the working state of the vehicle computer is switched to the flashing mode by calling a first mode switching instruction;

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

[0031] Step 103, when the debugging version software is successfully flashed, the official version software is flashed into the vehicle computer.

[0032] In step 101, when the flashing of the official version software of the vehicle computer fails and the vehicle computer has debugging authority, the working state of the vehicle computer is switched to the flashing mode by calling a first mode switching instruction;

[0033] In this embodiment, the execution subject is a flashing platform, and the flashing process is performed on the flashing platform. The flashing platform includes a host computer, and the host computer controls the vehicle computer to complete the flashing by sending control instructions.

[0034] Since after the official version of the vehicle computer has been flashed, if the official version is to be re-flashed, it is necessary to flash the debug software version before re-flashing, and then the official software version can be flashed again. Therefore, in this embodiment, the working state of the vehicle computer is switched to the flashing mode, and the debug version software is flashed in this flashing mode.

[0035] The above-mentioned flashing mode can be fastboot mode, which is a flashing mode of an Android device, mainly used to flash the debug version software to the vehicle computer through a USB data cable on the host computer. The above-mentioned debugging permission can be Android Debug Bridge (ADB) permission, which is used to obtain the flashing permission for the vehicle computer. The above-mentioned mode switching instruction can be adb reboot bootloader, which is an instruction corresponding to the debugging permission and is used to switch the working state of the vehicle computer to fastboot mode.

[0036] It should be noted that before calling the mode switching command, it is also necessary to run the command ADB reboot through the CMD command line on the flashing test bench to control the vehicle computer to power on and off, and then call the mode switching command. CMD is the Windows command prompt, which is a command line operation tool of the Windows system. Users can complete the power on and off of the vehicle computer by entering ADB reboot.

[0037] In step 102, in the flashing mode, the debugging version software is flashed into the vehicle computer;

[0038] It should be noted that the car computer includes three modules, namely the control module, the network module and the operation module. The operation module can be a system on chip (SOC), and the SOC can be an Android system, which is the operating system for the car computer to interact directly with the user and carries the upper-level system applications and multimedia applications. The control module can be a microcontroller unit (MCU): responsible for the basic computing and control work of the SOC. The network module can be a 5G module, which is responsible for the 5G networking module of the whole vehicle, mainly providing traffic Internet access and other services for the car computer.

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

[0040] In step 103, when the debugging version software is successfully flashed, the official version software is flashed into the vehicle computer.

[0041] In this embodiment, the steps for determining whether the debugging version software is successfully flashed include:

[0042] First, the test bench obtains the network connection status of the control module, network module and operation module through the ping command in the CMD command line; secondly, the test bench reads the software package version in the control module, network module and operation module through adb; when the network connection status of the control module, network module and operation module are all connected, and the software package version in the network module and the operation module is the same as the debug version software, the debug version software is flashed successfully.

[0043] In one 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, and firstly, ping172.31.2.51, ping172.31.2.53, and ping172.31.2.54 can all get replies, then the network connection status is considered to be connected. Secondly, the test bench can read the corresponding SOC, MCU, and 5G software versions through adb, which means that the flashing is successful.

[0044] After the debugging version software is successfully flashed, the flashing bench reads the official version software stored in the host computer and flashes the official version software to the vehicle computer.

[0045] In this embodiment, when the flashing of the official version software of the vehicle computer fails and the vehicle computer has debugging authority, the working state of the vehicle computer can be automatically switched to the flashing mode, and in the flashing mode, the debug version software can be flashed into the vehicle computer to prepare for flashing the official software version of the vehicle computer again. After the flashing of the vehicle computer fails, the second flashing can be started immediately, which can avoid the need for manual operation of the vehicle computer that has failed to flash and the problem of isolating the vehicle computer. At the same time, it can realize automatic flashing of the vehicle computer, reduce the waste of human resources caused by manual flashing, and improve the efficiency of flashing.

[0046] In one embodiment of the present application, flashing the debugging version software into the vehicle computer includes:

[0047] Controlling the vehicle computer to run a flashing script corresponding to the operating software package in the debugging version software, so that the operating software package is flashed into the vehicle computer;

[0048] When the flashing of the operating software package is completed, the flashing instruction corresponding to the debugging authority is called to flash the network software package into the vehicle computer.

[0049] In this embodiment, when flashing the debug version software, the operating software package and the network software package need to be flashed into the vehicle computer; therefore, when flashing the operating software package, a flashing script corresponding to the operating software package can be set in the debug software version, and after running the script, the operating software package can be directly flashed into the operating module in the vehicle computer. Specifically, the script can be the fastboot_all_and_erase_all.bat script.

[0050] After the flashing of the operating software package is completed, the flashing of the network software package is performed. The network software package can be flashed by calling a flashing instruction, wherein the flashing instruction includes an import instruction, a permission instruction, a write instruction, and an exit instruction.

[0051] In one embodiment, calling the flashing instruction corresponding to the debugging authority to flash the network software package to the vehicle computer includes:

[0052] Calling the opening instruction to control the vehicle computer to open the root authority;

[0053] Calling the import instruction to import the network software package into the network module in the vehicle computer;

[0054] Calling the permission instruction to enable the network module to enter an open permission mode;

[0055] Calling the write instruction to flash the network software package into the network module;

[0056] The exit instruction is called to cause the network module to exit the open authority mode.

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

[0058] In one example, the enable command may be adb root, which is to enable the root authority of the vehicle computer. Under the root authority, the flashing station can have the highest authority of the vehicle computer. At this time, the flashing station can perform all operations of adding, deleting, modifying, and checking any file in the vehicle computer (including system files). Only under the root authority can the subsequent steps be performed.

[0059] The import command can be adb push 5G software package / data / modefm / 5G, which 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, which is to switch the 5G module of the vehicle computer to edl mode, and lsusb to check whether the vehicle computer enters 9008 mode. The edl mode of the 5G module corresponds to the 9008 mode of the vehicle computer, and both are used to make the network module enter the open permission mode. The open permission module is the network module that opens its own control authority to the flashing platform, so that the flashing platform can flash the network software package to the network module.

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

[0062] The exit command 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 flashed.

[0063] In this embodiment, the debugging version software is flashed into the vehicle computer by calling the flashing instruction through the flashing station, thereby realizing automatic flashing of the flashing station without manual operation, reducing labor costs and improving flashing efficiency.

[0064] In one embodiment of the present application, when the flashing of the official version software of the vehicle computer fails and the vehicle computer has debugging authority, the working state of the vehicle computer is switched to the flashing mode by calling a first mode switching instruction, including:

[0065] If the flashing of the official version software of the vehicle computer fails and the vehicle computer has debugging authority, calling a first restart instruction corresponding to the debugging authority to control the vehicle computer to restart;

[0066] When the vehicle computer completes the restart, the working state of the vehicle computer is switched to the flashing mode by calling the first mode switching instruction.

[0067] In this embodiment, the first reboot instruction may be adb reboot. When the vehicle computer has debugging authority, in order to ensure that the debugging version software can be flashed smoothly and to ensure the success rate of flashing, the vehicle computer needs to be controlled to restart and the flashing mode of the vehicle computer is turned on.

[0068] In one embodiment of the present application, in the flashing mode, before flashing the debug version software to the vehicle computer, the method further includes:

[0069] In the case where flashing the official version software of the vehicle computer fails and the vehicle computer does not have debugging authority, in response to the received connection instruction, a preset flashing tool is connected to the vehicle computer so that the vehicle computer opens the debugging authority through the flashing tool;

[0070] The second mode switching instruction is called to switch the working state of the vehicle computer to the flashing mode.

[0071] In this embodiment, the connection instruction can be sent manually or automatically triggered by the flashing platform when it detects that the vehicle computer does not have the debugging permission. After the flashing tool is connected to the vehicle computer, the vehicle computer has the ADB permission, so that the debugging version software can be flashed.

[0072] The second mode switching instruction may be mdb-fastboot_hu_f, so that the vehicle computer enters the fastboot mode. Subsequently, the flashing station executes step 102 to flash the debugging version software into the vehicle computer.

[0073] In this embodiment, when the vehicle computer does not have debugging authority, the vehicle computer is connected to the flashing tool so that the vehicle computer has debugging authority, thereby completing the flashing of the debugging version software of the vehicle computer. This can improve the success rate of flashing the debugging version software of the vehicle computer, thereby improving the success rate of flashing the formal version software.

[0074] In one embodiment of the present application, when the debugging version software is successfully flashed, after the official version software is flashed into the vehicle computer, the method further includes:

[0075] Sending a first detection instruction to a control module, a network module and an operation module in the vehicle computer respectively, wherein the control module is used to flash the control software package in the official version software, the network module is used to flash the network software package in the official version software, and the operation module is used to flash the operation software package in the official version software;

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

[0077] When the first preset condition is met, it is determined that the official version software is successfully flashed:

[0078] The first preset condition includes:

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

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

[0081] In this embodiment, after the official version software is flashed into the car computer, the flashing result needs to be judged to determine whether it needs to be re-flashed. Therefore, it is possible to determine whether the official version software has been successfully flashed by obtaining the network connection status of each module in the car computer and the existing test version software in the car computer.

[0082] Specifically, the first detection instruction is a ping instruction, which obtains the network connection status of each module in the vehicle computer by pinging the IP address of each module in the vehicle computer. Whether the network connection status is connected is used as one of the conditions for whether the vehicle computer is successfully flashed. The software version to be tested includes the control software package version to be tested, the network software package version to be tested, and the operation software package version to be tested. The comparison of the versions of the software packages in the tested version and the official version software is used as one of the conditions for determining whether the flashing is successful.

[0083] When pinging the IP addresses of each module in the vehicle computer, if each module in the vehicle computer responds, it is considered that the network connections of each module are normal; when the network connections of each module are normal, if the version of the control software package to be tested is the same as the version of the software package in the flashed official version software, the version of the network software package to be tested is the same as the version of the network software package in the official version software, and the version of the operation software package to be tested is the same as the version of the operation software package in the official version software, it is considered that the flashing of the official version software is successful.

[0084] It should be noted that when judging the flashing result of the official version of the software, it is necessary to obtain the network connection status and the version of the software package of the control module, network module and operation module at the same time, while when judging the flashing result of the debug version of the software, it is only necessary to obtain the network connection status and the version of the software package of the network module and operation module.

[0085] In this embodiment, after the vehicle computer is re-flashed with the official version software, the connection status of each module in the vehicle computer and the version of the software package are obtained to determine whether the official version software is successfully flashed, which can ensure the success of the vehicle computer flashing, reduce misjudgment, and improve the work efficiency of the flashing.

[0086] In one embodiment of the present application, when the debugging version software is successfully flashed, flashing the official version software to the vehicle computer includes:

[0087] Invoking a second restart instruction corresponding to the debugging authority to control the vehicle computer to restart;

[0088] When the vehicle computer completes the restart, the official version software is flashed into the vehicle computer.

[0089] In this embodiment, the second restart instruction may be adb reboot. After the vehicle computer completes flashing the debugging version software, in order to ensure that the official version software can be flashed smoothly and to ensure the success rate of the flashing, the vehicle computer needs to be controlled to restart.

[0090] After the vehicle computer is restarted, the network software package of the official version software is flashed into the network module of the vehicle computer, the operation software package of the official version software is flashed into the operation module of the vehicle computer, and the control software package of the official version software is flashed into the control module of the vehicle computer.

[0091] Here, it should be noted that, unlike flashing the debug version software, when flashing the debug version software when the official version software fails, you only need to flash the operating software package and the network software package to the vehicle computer, and there is no need to flash the control software package.

[0092] In this embodiment, during the process of flashing the official version of the software, by controlling the vehicle computer to restart and flashing the software package in each module in the vehicle computer, the flashing success rate of the vehicle computer can be improved and the flashing can be ensured to be completed normally.

[0093] In one embodiment of the present application, the debugging version software is successfully flashed by the following steps:

[0094] Sending a second detection instruction to a control module, a network module and an operation module in the vehicle computer respectively, the control module is used to flash the control software package in the debug version software, the network module is used to flash the network software package in the debug version software, and the operation module is used to flash the operation software package in the debug version software;

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

[0096] If the second preset condition is met, determining that the debugging version software is successfully flashed;

[0097] The second preset condition includes:

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

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

[0100] In this embodiment, the second detection instruction mentioned above may refer to the first detection instruction, and the conditions for determining whether the debugging version software is successfully flashed are the same as the conditions for determining whether the official version software is successfully flashed, which will not be described in detail in this embodiment.

[0101] Figure 2 The figure shows the overall process diagram of the vehicle computer flashing method in one embodiment of the present application.

[0102] like Figure 2 As shown, step 201, inserting the vehicle computer, is to connect the flashing station and the vehicle computer;

[0103] Step 202, the vehicle computer starts checking the status, that is, obtaining the network connection status of the operation module, network module and control module in the vehicle computer through a ping command;

[0104] Step 203, start flashing, that is, flashing the official version of the software;

[0105] Step 204, whether the flashing is successful, is to determine whether the official version software is successfully flashed;

[0106] Step 205, the label machine prints a label, that is, after the official version of the software is successfully flashed, the label machine prints a label to indicate that the vehicle computer has been successfully flashed;

[0107] Step 206, flashing is completed;

[0108] Step 207, the host computer restarts the vehicle computer, that is, after the flashing of the official version of the software fails, the host computer in the flashing test bench controls the vehicle computer to restart;

[0109] Step 208, loading the test version software with the same software number, that is, re-flashing the debug version software after restarting.
