Description

Technical Field

[0001] The present invention relates to the field of automotive electronics, and in particular to a Bootloader flashing method, device, equipment and medium. Background Art

[0002] With the development of automotive electronic technology, the need to upgrade the automotive ECU (Electronic Control Unit) program has become increasingly important, and the stability and timeliness of the flashing process have also become increasingly stringent. By setting a Bootloader (a boot program in a fixed position in the ECU, the basis for upgrading automotive electronic functions) in the microcontroller, it is possible to implement functions that require software flashing system updates or normal startup. Microcontroller software often needs to be refreshed due to the need to update bugs or update functions, and the Bootloader meets the software refresh requirements.

[0003] Bootloader is the first code executed after the system is reset. Therefore, the loading and starting task of the entire system is completely completed by Bootloader. It first completes the initialization of the system hardware, including clock setting, memory mapping, etc. It also sets the stack pointer and then jumps to the entry of the operating system kernel. For example, when the system is powered on or reset, it usually starts execution from address 0x00000000, and the system's Bootloader program is usually stored at this address. In this way, the system's hardware and software environment is brought to a suitable state, so as to prepare the correct environment for the final call to the operating system kernel.

[0004] In order to test the stability of the Bootloader, after the Bootloader program is developed, several test apps (applications) need to be used to test the stability of the current Bootloader. This part of the work is originally done by the software test engineer who develops the Bootloader program, but thousands of repetitive work wastes a lot of manpower and time. There are tools such as Keyboard Wizard on the market that can complete repetitive work, but they are powerless in dealing with unexpected situations, flash pop-up errors, and controlling the start and stop time of flashing. Testers who use such tools have to stop the program running frequently and flash manually, which not only fails to achieve the goal of saving manpower, but makes the work more cumbersome. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a Bootloader flashing method, device, equipment and medium, which can effectively improve the efficiency of flashing. The specific scheme is as follows:

[0006] In a first aspect, the present application provides a Bootloader flashing method, which is applied to a preset stability test and error injection tool, including:

[0007] Configure the software and hardware environment for Bootloader flashing;

[0008] During the current round of Bootloader flashing, the preset stability test and error injection tool are started to record the mouse and keyboard actions, and it is determined whether the current test is an interruption test;

[0009] If yes, dynamically obtain the target coordinates in the current flashing page based on the preset image recognition interface, and obtain the corresponding target random number according to the target coordinates, so as to trigger the corresponding flashing interruption operation based on the target random number and start the next round of Bootloader flashing;

[0010] If not, after the recording is completed, the local automatic flashing program is started, and when it is determined based on the preset image recognition interface that a preset abnormal situation currently exists, the software abnormal situation is automatically processed or the hardware abnormal situation is automatically processed through the digital IO and the programmed power supply connected to the preset stability test and error injection tool to obtain the corresponding flashing results and the current round of stress test results; wherein, the hardware abnormal situation includes voltage mutation and excessive bus load.

[0011] Optionally, after obtaining the corresponding flashing result and the stress test result of the current round, the process further includes:

[0013] Optionally, after obtaining the corresponding flashing result and the stress test result of the current round, the process further includes:

[0015] Optionally, recording mouse and keyboard actions by starting the preset stability test and error injection tool includes:

[0016] The preset stability test and error injection tool is started by running a preset command line or a preset script in a preset interactive interface, and mouse and keyboard action recording is performed based on the preset stability test and error injection tool.

[0017] Optionally, the method further includes:

[0018] Select to perform normal flashing or interrupt testing through the preset interactive interface;

[0019] The preset interactive interface records and displays in real time the corresponding number of flashing times, number of flashing failures, flashing failure rate, total number of flashing times, interruption test success rate, and stress test success rate.

[0020] Optionally, obtaining a corresponding target random number according to the target coordinates to trigger a corresponding flash interrupt operation based on the target random number and start the next round of Bootloader flashing includes:

[0021] By converting the target coordinates into absolute coordinates, a target random number within a preset range is obtained according to the absolute coordinates, so that during the flashing process, a corresponding flashing interruption operation is triggered at every preset time unit of the target random number, and the next round of Bootloader flashing is started.

[0022] Optionally, the automatic identification and processing of abnormal situations based on the preset image recognition interface includes:

[0023] Automatically identify and process error reminders or error pop-up windows based on the preset image recognition interface by periodically creating a new thread.

[0024] In a second aspect, the present application provides a Bootloader flashing device, which is applied to a preset stability test and error injection tool, including:

[0025] Environment configuration module, used to configure the software and hardware environment for Bootloader flashing;

[0026] A judgment result acquisition module is used to record the mouse and keyboard actions by starting the preset stability test and error injection tool during the current round of Bootloader flashing, and to judge whether the current test is an interruption test;

[0027] The first result processing module is used to dynamically obtain the target coordinates in the current flashing page based on the preset image recognition interface, and obtain the corresponding target random number according to the target coordinates, so as to trigger the corresponding flashing interruption operation based on the target random number and start the next round of Bootloader flashing;

[0028] The second result processing module is used to start the local automatic flashing program after the recording is completed, and when it is determined based on the preset image recognition interface that a preset abnormal situation currently exists, automatically process the software abnormal situation or automatically process the hardware abnormal situation through the digital IO and the programmed power supply connected to the preset stability test and error injection tool to obtain the corresponding flashing result and the current round of stress test results; wherein, the hardware abnormal situation includes voltage mutation and excessive bus load.

That is to say, this application first configures the software and hardware environment of flashing, and then records the mouse and keyboard actions in the current round of flashing by starting the preset stability test and error injection tool, and determines whether it is an interruption test. If yes, then determine the corresponding target random number to trigger the corresponding interruption test process based on the target random number; if not, automatically flash after the recording is completed, and automatically identify and handle software anomalies in this process as well as hardware anomalies including voltage mutation, excessive bus load, etc. In this way, on the one hand, it can effectively reduce unnecessary waste of human resources and time resources, improve the efficiency of Bootloader flashing, and realize the automation of flashing. On the other hand, through interruption testing and stress testing, the stability of the Bootloader during flashing is automatically tested, and automatic identification and handling of emergencies are realized.

[0045] 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 only 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.

[0046] In order to test the stability of the Bootloader, after the Bootloader program is developed, it is necessary to use several test apps to test the stability of the current Bootloader. This part of the work is originally done by the software test engineer who develops the Bootloader program, but thousands of repeated work wastes a lot of manpower and time. There are tools such as Keyboard Wizard on the market that can complete repetitive work, but they are powerless in dealing with unexpected situations, flashing pop-up errors, and controlling the start and stop time of flashing. Testers using such tools have to often stop the program from running and flash manually, which not only fails to achieve the goal of saving manpower, but makes the work more cumbersome. To this end, the present application provides a Bootloader flashing solution that can effectively improve the efficiency of Bootloader flashing.

[0047] See also Figure 1 As shown, an embodiment of the present invention discloses a Bootloader flashing method, which is applied to a preset stability test and an error injection tool, including:

[0048] Step S11, configuring the software and hardware environment for Bootloader flashing.

[0049] In this embodiment, the software and hardware environment required for the current Bootloader flashing needs to be configured first, so that a series of operations can be performed in the configured environment later.

[0050] Step S12: During the current round of Bootloader flashing, the preset stability test and error injection tool are started to record the mouse and keyboard actions, and it is determined whether the current test is an interruption test.

[0051] Specifically, in this embodiment, it is necessary to understand that the preset stability test and error injection tool needs to be started for recording while the normal process is manually flashed once. The recorded content can be specifically recorded in a txt (short for text) document, which realizes the capture and recording of a single action. At the same time, the current txt document can be edited and modified. If some functions need to be changed later, there is no need to re-record the txt script. And there are two ways to start the tool, that is, the recording of mouse and keyboard actions by starting the preset stability test and error injection tool, including: starting the preset stability test and error injection tool by running a preset command line or a preset script in a preset interactive interface, and recording mouse and keyboard actions based on the preset stability test and error injection tool. Among them, regarding the preset script in the preset interactive interface, the preset script is directly run by running the exe file in the preset interactive interface to start the tool. During this process, you need to start the user interaction page of pyqt (a toolkit for creating GUI applications). The user interaction page is more intuitive. Selecting a project on the page requires a script. Script editing is also reflected in the page, and you can directly open a txt document on the page to edit the script. The page provides an error image upload function, through which you can read error pop-ups or correct pop-ups. There is a dynamic box on the page to dynamically display the console parameters during the project operation. The mouse precision can be controlled by changing the mouse precision to control the accuracy of mouse clicks or mouse movements during the project operation, and the mouse precision can be adjusted according to different needs.

[0052] Regarding the command line, there may specifically be the following code segments:

[0053] parser=argparse.argumentParser()

[0054] parser.add_argument

[0055] In this way, the scripts that need to be parsed in this project, the number of times the project needs to be looped, the execution speed and other parameters are added to the project. Since the command line does not need to start the user interaction page, the command line does not need to start the UI (User Interface) page function, so in theory it can save more computer performance.

[0056] Furthermore, in this embodiment, it also includes: selecting to perform normal flashing or interruption test through the preset interactive interface; recording and displaying the corresponding flashing times, flashing failure times, flashing failure rate, total flashing times, interruption test success rate, and stress test success rate in real time through the preset interactive interface. In this way, the failure rate can be obtained more intuitively than using the command line.

[0057] Step S13: If yes, dynamically obtain the target coordinates in the current flashing page based on the preset image recognition interface, and obtain the corresponding target random number according to the target coordinates, so as to trigger the corresponding flashing interruption operation based on the target random number and start the next round of Bootloader flashing.

[0058] Specifically, in this embodiment, the target random number is obtained according to the target coordinates, so as to trigger the corresponding flash interruption operation based on the target random number and start the next round of Bootloader flashing, including: converting the target coordinates into absolute coordinates, obtaining the target random number within the preset range according to the absolute coordinates, so as to trigger the corresponding flash interruption operation at each preset time unit of the target random number in the flashing process, and start the next round of Bootloader flashing. Among them, the preset range can be configured and adjusted in advance based on actual needs, and the preset time unit can be configured and adjusted in advance based on actual needs. That is to say, in this embodiment, the stability of the Bootloader is tested through the interruption test of the Bootloader, and the target coordinates in the flashing page can be dynamically obtained through OpenCv (Open Source Computer Vision Library, open source computer vision library)-python (a Python wrapper implemented in C++ of the OpenCV library) through the preset image recognition interface, and the relative coordinates are converted into absolute coordinates. Through this coordinate, a random number within a specified range is generated in each interruption test, so as to achieve interruption at each interval of the corresponding random time in each automated test.

[0059] It should be understood that the stability of the Bootloader needs to be tested in the Bootloader test, because in actual use, there may be a sudden power outage or other uncertain factors during the flashing process. If the stability of the Bootloader is not enough, the next time the power is turned on again and the flashing is done again, there will be uncontrollable results such as program disorder and inability to start. Therefore, the stability of the Bootloader needs to be guaranteed before mass production, which requires the test engineer to perform an interruption test. In this embodiment, the interruption test is performed by generating a random number, and this interruption time can also be manually set in the UI page of the tool. Further, regarding the generation of random numbers, since an interruption test is required when testing the stability of the Bootloader, and such an interruption is uncertain in the actual Bootloader flashing process, it is necessary to use a method to interrupt the Bootloader with an uncertain interruption time. This interruption time is generated by a random number generator. In this embodiment, the input of the interruption time is added to the user UI, and then a random number is generated within this time range. This random number is used as the interruption time, which not only simulates the interruption test but also realizes the randomness of the interruption.

[0060] Step S14, if not, then after the recording is completed, the local automatic flashing program is started, and when it is determined based on the preset image recognition interface that a preset abnormal situation currently exists, the software abnormal situation is automatically processed, or the hardware abnormal situation is automatically processed through the digital IO and the programmed power supply connected to the preset stability test and error injection tool to obtain the corresponding flashing result and the current round of stress test results; wherein, the hardware abnormal situation includes voltage mutation and excessive bus load.

[0061] In this embodiment, the automatic identification and processing of abnormal situations based on the preset image recognition interface includes: automatically identifying and processing error reminders or error pop-ups based on the preset image recognition interface by creating a new thread at a fixed time. Specifically, by parsing the recorded txt script, and then calling pywinnk and win32api to execute the results of the parsed script, the script can be repeatedly executed. After that, the script is run by obtaining the results of the script parsing, and in the process of running the script, image recognition (opencv) is used to monitor the various error messages that appear on the screen in real time, and reset to a suitable state after automatic processing, so as to handle several abnormal conditions without affecting the next flash. In addition, this embodiment automatically detects the system category at the program startup time by writing the API (Application Programming Interface) of different operating systems into the function, and then automatically calls the API of different operating systems, so that the software applied to this embodiment is compatible with different operating systems.

[0062] It is necessary to further understand that after obtaining the corresponding flashing results and the current round of stress test results, it also includes: jumping back to the step of starting the local automatic flashing program, starting the next round of stress testing, until the preset round of stress testing is completed. Or, jumping back to the step of configuring the software and hardware environment for Bootloader flashing, starting the next round of stress testing, until the preset round of stress testing is completed. It is understandable that when changing the operating system, it is necessary to jump back to the step of configuring the software and hardware environment for Bootloader flashing for the next round.

[0063] In addition, since abnormal situations may occur in the actual Bootloader flashing process, they are specifically divided into two types: software abnormal situations and hardware abnormal situations. Among them, software abnormal situations are abnormal situations caused by problems with the Bootloader itself; hardware abnormal situations include but are not limited to device power failure, excessive bus load, and voltage mutation. Since the previous test tools can only realize software-level simulation, when circuit problems occur, they can only be solved manually by test engineers, which not only affects the timeliness of the work but also increases the workload of test engineers. If the bus load is too high, it can only be solved manually by engineers. However, in this embodiment, various abnormal situations that may occur in the actual flashing of the Bootloader can be automatically realized by the preset stability test and error injection tool. For hardware abnormal situations, the specific implementation method is to use digital IO (Input / Output) and system control to automatically control the circuit through a program power supply connected to the preset stability test and error injection tool to complete the corresponding hardware abnormal situation processing.

[0064] It can be seen that in the embodiment of the present application, the software and hardware environment of the Bootloader flashing is configured; in the current round of the Bootloader flashing process, the mouse and keyboard actions are recorded by starting the preset stability test and error injection tool, and it is determined whether the current is an interruption test; if so, the target coordinates in the current flashing page are dynamically obtained based on the preset image recognition interface, and the corresponding target random number is obtained according to the target coordinates, so as to trigger the corresponding flashing interruption operation based on the target random number and start the next round of Bootloader flashing; if not, after the recording is completed, the local automatic flashing program is started, and when it is determined based on the preset image recognition interface that there is a preset abnormal situation, the software abnormal situation is automatically processed or the hardware abnormal situation is automatically processed through the digital IO and the program power supply connected to the preset stability test and error injection tool to obtain the corresponding flashing result and the current round of stress test results; wherein the hardware abnormal situation includes voltage mutation and excessive bus load. That is to say, the present application first configures the software and hardware environment of the flashing, and then records the mouse and keyboard actions in the current round of the flashing process by starting the preset stability test and error injection tool, and determines whether it is an interruption test. If yes, then determine the corresponding target random number to trigger the corresponding interruption test process based on the target random number; if not, automatically flash after the recording is completed, and automatically identify and handle software anomalies in this process as well as hardware anomalies including voltage mutation, excessive bus load, etc. In this way, on the one hand, it can effectively reduce unnecessary waste of human resources and time resources, improve the efficiency of Bootloader flashing, and realize the automation of flashing. On the other hand, through interruption testing and stress testing, the stability of the Bootloader during flashing is automatically tested, and automatic identification and handling of emergencies are realized.

[0065] Combine the following Figure 2-Figure 8 The code segments disclosed in the text further illustrate the technical solutions of the embodiments of the present application.

[0066] In this embodiment, firstly, the preset stability test and error injection tool are compatible with different operating systems, a) Windows system; b) Linux or Darwin system. Specifically, the Linux or Darwin system can be configured with the following code segment.

[0067]

[0068] At the same time, the default region can be set to China, and the default language can be set to Chinese, which can be adjusted if necessary. And if the required script does not exist, this embodiment can automatically create a txt document named current time, which can be implemented by configuring the code segment shown below.

[0069]

[0070] Afterwards, in this embodiment, the running project can be controlled by the set hotkeys, which can be specifically configured as follows: Figure 2 as well as Figure 3 In this embodiment, after recording is completed, when parsing the recorded script, the delay function time, event type, coordinate point in the script are parsed and stored in the variable ScriptEvent; due to the format of the script, the comments and separators in the script need to be removed first, and the final required data is obtained before transferring. The specific implementation code segment can be seen in Figure 4 and Figure 5 As shown. Regarding running scripts, the parsed content of the script is stored in ScriptEvent. The script is run by reading the data in ScriptEvent. The control function that needs to delay a random time in the interrupt test is also written in the function of running the script. The flashing project is interrupted by a random number; the information of the running script and the pause, start and stop status are displayed on the page. Users can see the current flashing process and the remaining times in real time. For the specific implementation code snippet, please refer to Figure 6 and Figure 7 As shown. In this embodiment, abnormal situations during code execution are also monitored in real time. Specifically, a new thread can be created for image recognition. The thread starts running when the project is started. The thread can be set to start at a specific time in the preset stability test and error injection tool. On the one hand, starting multiple threads at the same time will affect part of the computer's performance. On the other hand, controlling the start and stop time of the thread can determine the real-time nature of different error pop-ups or success pop-ups, avoiding monitoring errors caused by monitoring the thread for too long. Specifically, a timing function can be triggered at fixed intervals to monitor the correct pop-ups or error pop-ups that appear on the screen in real time. For the specific implementation code snippet, see Figure 8 shown.
