Description

Technical Field

[0001] The present application relates to the field of flash writing test technology, and in particular to an automated FBL flash writing test method and device based on CAPL language. Background Art

[0002] In the development and verification process of modern automotive electronic control systems (ECUs), flash testing plays a vital role. It aims to ensure the safety performance of ECU software during the update process, thereby preventing software failures in actual vehicle operation.

[0003] In the traditional flash test method, the main focus is on the forward use case test, but there are obvious limitations in its execution: for example, after each test case is completed, the next use case needs to be manually reloaded, and when the test case encounters inconsistent responses during execution, the test tool will automatically stop the subsequent operations of the use case and cannot continue to execute the remaining test steps, thus failing to fully evaluate the flash capability of the ECU under abnormal conditions; in addition, when testing the transmission service alone, due to the lack of flexible control and simulation capabilities, it is difficult for testers to effectively simulate various transmission scenarios in actual working conditions, such as network delays, packet loss, etc. This not only reduces the test efficiency, but also increases the risk of human error, further limiting the comprehensiveness and accuracy of the test. It can be seen that it is particularly important to provide a method that can improve the accuracy of the flash test. Summary of the invention

[0080] Embodiment 1

[0081] See also Figure 1 , Figure 1 This is a flow chart of an automated FBL flash test method based on CAPL language disclosed in the embodiment of the present application. Figure 1 The described CAPL-based automated FBL flash test method can be applied to the development and testing of automotive electronic systems, especially in scenarios where automotive electronic control units (ECUs) need to be flashed and verified. Optionally, the method can be implemented by a flash test device, which can be integrated into a flash test device (such as a CANoe platform), or can be a local server or cloud server for processing the flash test process, etc., which is not limited in the embodiments of the present application. Figure 1 As shown, the CAPL language-based automated FBL flash writing test method may include the following operations:

[0082] 101. Use scripting language to write the target function for the boot loader forward flashing test.

[0083] In the embodiment of the present application, the scripting language may be CAPL language, and the boot loader, i.e., FBL (Firmware Boot Loader), is responsible for loading and running a higher-level boot loader or operating system when the system starts, which is usually used in embedded systems such as mobile phones, tablet computers or other hardware devices. Optionally, the target function includes a message sending and receiving function, a result comparison function, a security access operation function and an integrity check function, and also includes a file extraction function.

[0084] It should be noted that the following functions can be achieved by using CAPL language to write the objective function:

[0085] First, use CAPL language to write UDS (unified diagnostic service) diagnostic sending function and receiving function (message sending and receiving function) to realize single-frame / multi-frame sending and single-frame / multi-frame receiving of messages.

[0086] Second, use the CAPL language to write a function to determine whether the expected result is consistent with the actual result (i.e., the result comparison function) to automatically check the expected result against the actual result.

[0087] Third, use CAPL language to write security access operation functions to achieve unlocking and use in the subsequent flashing process.

[0088] Fourth, use CAPL language to write CRC32 check function (i.e. integrity check function) to check programming integrity during subsequent flashing.

[0089] Fifth, use CAPL language to write and extract Flash Driver files and APP files (i.e., file extraction function) for use in subsequent flashing and transmitting data.

[0090] 102. According to the objective function, a forward flashing test operation is performed on the boot loader to obtain a forward flashing test result corresponding to the boot loader.

[0091] In the embodiment of the present application, the forward flash test result may include a comparison result between the first test result to be verified (ie, the actual forward flash test result) and the expected forward flash result parameter.

[0092] 103. Determine test requirement parameters for a reverse flash test of the boot loader program, and perform a reverse flash test operation on the boot loader program according to the test requirement parameters to obtain a reverse flash test result corresponding to the boot loader program.

[0093] In an embodiment of the present application, the reverse flashing test result may include a comparison result between the second test result to be verified (i.e., the actual reverse flashing test result) and the expected reverse flashing result parameter. Optionally, the test requirement parameters include at least one of a transmission word count error test parameter, a transmission counter error test parameter, a data block repeated transmission test parameter, and a transmission length error test parameter. In this way, the reverse flashing use case in the flashing test is solved, and the reverse use case test requirements can be covered.

[0094] 104. Determine a target flashing test result of the boot loader according to the forward flashing test result and the reverse flashing test result.

[0095] In the embodiment of the present application, for example, whether the flash test of the boot loader is successful, whether there is a serious flash error, etc. is determined based on the degree of result matching in the forward flash test result and the degree of result matching in the reverse flash test result.

[0096] It can be seen that the implementation of the embodiments of the present application can realize the automated forward and reverse flash testing of the boot loader and obtain the target flash testing results. In this way, through the dual verification of the forward flash testing and the reverse flash testing, the flash testing errors caused by human factors can be reduced, and the execution reliability and accuracy of the software flash testing can be improved; at the same time, by writing the target function in a scripting language (such as CAPL), an automated testing process is realized, which improves the execution efficiency of the software flash testing.

[0097] In an optional embodiment, the target function for the boot loader forward flashing test written in a scripting language in step 101 above includes:

[0098] Determine the message sending and receiving requirement parameters of the unified diagnostic service corresponding to the boot loader;

[0099] According to the message sending and receiving requirement parameters of the unified diagnostic service, a message sending and receiving function for the boot loader forward flashing test is written in a scripting language.

[0100] In this optional embodiment, the message sending and receiving requirement parameters may include at least one of the message sending object parameters (e.g., the message object to be sent is ECU), message sending and receiving time parameters, message sending and receiving content, message sending and receiving frame number parameters (e.g., data below 8 bytes needs to be sent / received in a single frame, and data above 8 bytes needs to be sent / received in multiple frames), and message sending and receiving response parameters. Further, the message sending function and other target functions may be automatically written, or may be set and modified by the user through an interface or configuration file.

[0101] It can be seen that this optional embodiment can write a message sending and receiving function for the forward flash test according to the message sending and receiving requirement parameters corresponding to the boot loader. In this way, the flexibility, reliability and accuracy of the writing of the message sending and receiving function can be improved, and a variety of complex communication scenarios can be simulated, so as to comprehensively verify the performance of the boot loader under different conditions, so as to quickly and accurately locate and repair problems.

[0102] In another optional embodiment, the target function for the boot loader forward flashing test written in the scripting language in the above step 101 further includes:

[0103] Determine the security access requirement parameters for unified diagnostic services;

[0104] According to the security access requirement parameters of the unified diagnostic service, a security access operation function for the bootloader forward flash test is written in a scripting language.

[0105] In this optional embodiment, optionally, the security access requirement parameter includes at least one of an access detection object requirement parameter, an access response time requirement parameter, and a key verification requirement parameter.

[0106] It should be noted that when writing security access operation functions, since ECUs usually have multiple security access levels, each level corresponds to different operation permissions and data access ranges, the management of different security access levels should be considered, and the relevant security verification and key exchange should be changed.

[0107] It can be seen that this optional embodiment can write a security access operation function for the forward flash test according to the security access requirement parameters corresponding to the boot loader. This greatly enhances the security and reliability of the forward flash test, and can comprehensively evaluate the performance of the boot loader in response to security challenges, thereby ensuring the security and stability of the ECU in actual operation.

[0108] In yet another optional embodiment, the target function for the boot loader forward flashing test written in a scripting language in step 101 above further includes:

[0109] Determine the integrity verification requirement parameters for unified diagnostic services;

[0110] According to the integrity verification requirement parameters of the unified diagnostic service, an integrity verification function for the boot loader forward flashing test is written in a scripting language.

[0111] In this optional embodiment, the integrity check function may be a CRC32 check function. Optionally, the integrity check requirement parameter includes at least one of a check mode requirement parameter, a check response time requirement parameter, and a check object requirement parameter. Generally speaking, integrity checks are usually performed for specific data blocks or files. When writing a check function, it should be clearly specified which data needs to be checked, as well as the scope of the check (such as the entire file, a specific part of a file, or a specific data block), etc.

[0112] It can be seen that this optional embodiment can write an integrity verification function for the forward flash test according to the integrity verification requirement parameters corresponding to the boot loader. In this way, it can ensure that the data transmitted and stored during the flashing process maintains its originality and accuracy, effectively preventing the risk of data damage or tampering, which is beneficial to improving the security and stability of the boot loader.

[0113] In yet another optional embodiment, the target function for the boot loader forward flashing test written in a scripting language in step 101 above further includes:

[0114] Determine the result comparison requirement parameters of the unified diagnostic service;

[0115] According to the result comparison requirement parameters of the unified diagnostic service, a result comparison function for the bootloader forward flashing test is written in a scripting language.

[0116] In this optional embodiment, optionally, the result comparison requirement parameters include result comparison object requirement parameters (such as defining specific objects that need to be compared, such as diagnosis codes, status codes, data fields, etc.), result response type requirement parameters (such as positive response type, negative response type), result response time requirement parameters and at least one of expected result requirement parameters.

[0117] It can be seen that this optional embodiment can write a result comparison function for the forward flash test according to the result comparison requirement parameters corresponding to the boot loader. In this way, there is no need to manually test and compare the test results one by one, so that response delays or failures can be detected in time, thereby improving detection reliability and accuracy. In addition, it can also reduce environmental costs and manpower investment in testing, providing strong support for the optimization and improvement of the boot loader.

[0118] Embodiment 2

[0119] See also Figure 2 , Figure 2 : is a flowchart of another CAPL language-based automated FBL flash test method disclosed in the embodiment of the present application. Figure 2 The described CAPL-based automated FBL flash test method can be applied to the development and testing of automotive electronic systems, especially in scenarios where automotive electronic control units (ECUs) need to be flashed and verified. Optionally, the method can be implemented by a flash test device, which can be integrated into a flash test device (such as a CANoe platform), or can be a local server or cloud server for processing the flash test process, etc., which is not limited in the embodiments of the present application. Figure 2 As shown, the CAPL language-based automated FBL flash writing test method may include the following operations:

[0120] 201. Use scripting language to write the target function for the boot loader forward flashing test.

[0121] 202. According to the message sending and receiving function, a forward flash test request is sent to a preset flash test request object, and it is determined whether a first processing response result sent by the flash test request object is received. If so, it is determined whether a security access operation is required to the flash test request object.

[0122] In an embodiment of the present application, for example, when judging whether it is necessary to perform a security access operation on the flash test request object, it can be based on multiple factors, such as: 1. The sensitivity of the request: When the flash operation involves sensitive data or critical functions, additional security access verification may be required; 2. User permissions: Check whether the current user or process has the permission to perform security access operations; 3. Security policy: Determine whether it is necessary to perform a security access operation based on the security policy of the system or application.

[0123] 203. When it is determined that a security access operation needs to be performed on the flash test request object, a security access operation is performed on the flash test request object according to a security access operation function and using preset key parameters.

[0124] 204. After the security access operation is completed, determine, based on the integrity check function, whether the integrity of the data transmitted between the flash test request object is greater than or equal to a preset integrity threshold.

[0125] In the embodiment of the present application, optionally, the integrity check function may be CRC, HMAC, MD5, SHA-256, etc.

[0126] 205. When it is determined that the value is greater than or equal to the integrity threshold, a forward flash test operation is performed on the boot loader to obtain a first test result to be verified, and a forward flash test result corresponding to the boot loader is determined based on the first test result to be verified and a result comparison function.

[0127] In an embodiment of the present application, further, the method also includes: when it is determined that the degree of integrity is less than a threshold value, performing an error handling operation, wherein the error handling operation includes at least one of an error log recording operation, an error report sending operation, and a retry transmission operation.

[0128] Furthermore, a forward flash test operation is performed on the bootloader to obtain a first test result to be verified, including:

[0129] According to the file extraction function, a preset driver file and / or application file is extracted, and based on the driver file and / or application file, a forward flashing test operation is performed on the boot loader to obtain a first test result to be checked.

[0130] In the embodiment of the present application, the first test result to be verified is the actual test result in the forward flash test process.

[0131] 206 . Determine test requirement parameters for a reverse flash test of the boot loader program, and perform a reverse flash test operation on the boot loader program according to the test requirement parameters to obtain a reverse flash test result corresponding to the boot loader program.

[0132] 207. Determine a target flashing test result of the boot loader according to the forward flashing test result and the reverse flashing test result.

[0133] In the embodiment of the present application, for other descriptions of step 201, step 206 and step 207, please refer to the detailed description of step 101, step 103 and step 104 in embodiment 1, and the embodiment of the present application will not be repeated.

[0134] It can be seen that the implementation of the embodiment of the present application can perform a forward flash test operation on the boot loader according to the target function, and perform a reverse flash test operation on the boot loader according to the test requirement parameters, thereby obtaining a target flash test result of the boot loader. In this way, through the forward flash test and the reverse flash test, the flash test reliability and stability of the boot loader can be improved, and then the security and compliance of the test process can be improved, thereby providing users with a better flash test experience.

[0135] In an optional embodiment, in the above step 206, performing a reverse flash test operation on the boot loader according to the test requirement parameters to obtain a reverse flash test result corresponding to the boot loader includes:

[0136] Sending a reverse flash test request to the flash test request object, and determining whether a second processing response result sent by the flash test request object is received;

[0137] When the judgment result is yes, the boot loader is reversely flashed according to the test requirement parameters to obtain a second test result to be verified, and the reverse flash test result corresponding to the boot loader is determined according to the second test result to be verified and the preset expected reverse flash result parameters.

[0138] In this optional embodiment, a Panel interface may also be written to implement visual file loading operations to implement flash type (such as CAN type or CANFD type) and request ID selection operations.

[0139] It can be seen that this optional embodiment can ensure the initiative and controllability of the flash test by sending a reverse flash test request to the flash test request object and waiting for its response. This two-way communication mechanism not only improves the flexibility of the test, but also can promptly discover and deal with potential problems during the test, thereby improving the efficiency and accuracy of the test, and providing strong data support for subsequent optimization and improvement.
