It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the disclosed embodiments described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0031] Unless otherwise stated, the term "plurality" means two or more.

[0032] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0033] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0034] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0035] Combination Figure 1 As shown, the embodiment of the present disclosure provides a method for controlling an application process, the execution subject of the method may be a processor, and the method includes:

[0036] S001, when receiving a storage access command sent by an external device, the processor parses the storage access command to obtain a storage area to be accessed and an operation to be accessed; wherein the storage area to be accessed includes a storage name to be accessed or a storage address to be accessed.

[0037] S002, the processor determines a target storage address based on a space mapping table and according to a storage name to be accessed or a storage address to be accessed; wherein the space mapping table is used to store the name, address and access permission of the storage area inside the application.

[0038] S003, the processor performs a pending access operation on the target storage address.

[0039] S004, when the access operation is a write storage operation, the processor modifies the storage value of the target storage address and executes the corresponding application control flow according to the modified storage value.

[0040] In the disclosed embodiment, the target storage address corresponding to the storage area to be accessed in the storage access command can be found according to the space mapping table, and the access to the internal storage of the application can be achieved by executing the operation to be accessed on the target storage address. The space mapping table is used to store the name and address of the internal storage area of ​​the application. Therefore, when the operation to be accessed is a write data operation, the storage value of the target storage address is modified, and the corresponding application control process is executed according to the modified storage value, so that the debugger can locate the problem of the application according to the execution process and the expected process, and debug the application, so that the application functions in various scenarios can be tested, the test coverage is improved, and the debugging efficiency is improved.

[0041] Optionally, the storage access command includes storage characteristics, access rights, access rules, access start address, access length, and other commonly agreed parameters.

[0042] The access storage command is a request sent by an external device or system to an application, including multiple key parameters. Among them, the characteristics of the storage include the type, name or identifier of the storage, and the type of data stored, which helps the application identify and locate a specific storage area. Access rights define the access level of the external entity executing the command to the specified storage area, such as read-only, write-only, or read-write. Access rights ensure the security of the data and prevent unauthorized modification or access. Access rules define the conditions or constraints that must be followed when accessing storage. For example, it may be stipulated that certain data can only be accessed within a specific time window, or that access must follow a specific order or pattern. The access start address specifies the starting position of the data block to be accessed, which is usually used for low-level programming or direct memory access, where data is stored at a specific memory address. The access length specifies the size or length of the data block to be accessed, which can be the number of bytes, bits, or other units, depending on the type of data stored and the architecture of the system. Other commonly agreed parameters include cryptographic signatures, timestamps, session identifiers, etc. used to verify the validity of commands. These parameters help ensure the integrity of commands and the reliability of their sources to prevent tampering and replay attacks.

[0043] Combination Figure 2 As shown, the embodiment of the present disclosure provides another method for controlling an application process, including:

[0044] S101: The processor obtains a storage access command sent by an external device.

[0045] S102, the processor determines whether the access storage command is an access internal storage command, if so, executes S103, if not, executes S112.

[0046] S103: The processor parses the storage access command to obtain the storage area to be accessed and the operation to be accessed.

[0047] S104, the processor determines whether the storage area to be accessed matches the storage name to be accessed, and if so, executes S105, otherwise executes S113.

[0048] S105: The processor determines a target storage address based on the space mapping table and the storage name to be accessed.

[0049] S106, the processor determines whether the address legitimacy check of the target storage address has passed, if the check has passed, execute S107, if not, execute S115.

[0050] S107, the processor determines whether the permission check of the target storage address passes, if the check passes, executes S108, if not, executes S115.

[0051] S108: The processor performs a pending access operation on the target storage address.

[0052] S109: After the access operation is completed, the processor returns a success response.

[0053] S110, when the access operation is a write storage operation, the processor modifies the storage value of the target storage address and executes the corresponding application control flow according to the modified storage value.

[0054] S111, the processor ends the external access operation of the application.

[0055] S112: The processor executes other processes corresponding to the access storage command.

[0056] S113, the processor determines whether the storage area to be accessed matches the storage address to be accessed, and if so, executes S114, and if not, executes S115.

[0057] S114, the processor determines the target storage address based on the space mapping table and the storage address to be accessed, and executes S106.

[0058] S115, the processor determines that the internal access to the storage fails, and returns a failure response.

[0059] Optionally, based on the space mapping table, according to the storage name to be accessed or the storage address to be accessed, the target storage address is determined, including: matching the storage name to be accessed or the storage address to be accessed with the space mapping table to determine the target storage address; and verifying the target storage address.

[0060] In this embodiment, the space mapping table is stored inside the application, and multiple memory storage attributes are stored. The memory storage attributes include storage name, storage space, storage type and access rights. Memory storage includes variables, structures, single members of structures, memory block storage, data members, member functions or variable pointers. Memory storage can occupy one byte or more bytes of space. The access rights of memory storage are divided into read-only, write-only, read-write or no access allowed. Read-write permissions satisfy the permissions of separate read and write at the same time. The read-write permissions in the access rights can be closed or opened according to the product stage. Read-write permissions are set in the development and debugging stage of the application. When the application is released, some memory access rights need to be closed for the safety or reliability of the application. The access mode of memory storage is divided into byte alignment (8 bits), half-word alignment (16 bits) or word alignment (32 bits), and it is necessary to access according to the specified alignment mode. The name, address and access rights of all storage areas inside the application are stored in the space mapping table, and the name of the storage area is unique under the premise of pre-agreement with external visitors. Therefore, when a storage access command is received, the storage name to be accessed or the storage address to be accessed in the storage access command can be matched with the space mapping table, so as to determine the target storage address in the space mapping table.

[0061] Optionally, the storage name to be accessed or the storage address to be accessed is matched with the space mapping table to determine the target storage address, including: when the storage name to be accessed successfully matches the name of the application's internal storage area in the space mapping table, determining the address corresponding to the successfully matched name in the space mapping table as the target storage address; or, when the storage address to be accessed successfully matches the address of the application's internal storage area in the space mapping table, determining the successfully matched address in the space mapping table as the target storage address.

[0062] In this embodiment, it can be determined whether the parameter of the access storage command is matched according to the storage name to be accessed or the storage address to be accessed. If the matching is performed according to the storage name to be accessed, it is necessary to first determine the name of the storage area with the same storage name as the storage name to be accessed in the space mapping table, and then determine the address corresponding to the name as the target storage address. If the matching is performed according to the storage address to be accessed, the address of the storage area with the same storage address to be accessed is directly determined in the space mapping table as the target storage address.

[0063] Optionally, the storage access command also includes an access start address and an access length; the target storage address is verified, including: determining the access address segment based on the access start address and the access length; judging whether the access address segment is within the address range of the target storage address, if so, the address legitimacy check passes; judging whether the access address segment satisfies the access permissions in the space mapping table, if so, the permission check passes.

[0064] In this embodiment, after determining the target storage area, the target storage area needs to be verified. According to the access start address and access length in the access storage command, the access address segment corresponding to the access storage command can be determined, and then the access address segment is verified for legitimacy and permission to ensure that the space to be accessed is within the address range of the target storage address and meets the access permission to prevent cross-border access.

[0065] Optionally, verifying the target storage address further includes: obtaining a security authentication message of a storage access command; and verifying the security authentication message.

[0066] In this embodiment, the access permission can also increase the verification access, and determine that the access storage command has been security authenticated by both parties through the security authentication message in the access storage command. In addition, the access storage command can be encrypted for transmission, and the access storage command is encrypted with the encryption key agreed upon by the handshake between the two parties before being transmitted. The receiving party decrypts the access storage command according to the predetermined key before using it.

[0067] Optionally, the access operation includes a read data operation and a write data operation, and performing the access operation on the target storage address includes: reading the storage data of the target storage address, or writing the data to be written to the target storage address; after the access operation is completed, returning a success response.

[0068] In this embodiment, a corresponding data read operation or data write operation is performed according to the operation to be accessed, and after the operation to be accessed is completed, a success response is returned to continue to execute subsequent steps.

[0069] Optionally, the corresponding application control process is executed according to the modified storage value, including one or more of the following: when the modified storage value is a message queue, signal, mailbox or event in a multi-tasking system, the scheduling task is suspended or resumed; when the modified storage value is a human-machine interface storage, a predetermined human-machine interface is displayed; when the modified storage value is a variable controlled by a loop, the number of executions of the loop is controlled or the loop is exited; when the modified storage value is a function pointer, the expected specified function function is called to run and enter a predetermined application branch; when the modified storage value is a register configuration value, the interface function register configuration value is modified.

[0070] In this embodiment, for a multi-task system, taking a message queue as an example, a message queue can be sent to another task in one task, for example, another task is scheduled to run. After another task receives the message, the operating system performs task scheduling, runs the task waiting for the message queue, and suspends the current task. For signal events in a multi-task system, the operating system is triggered to perform task scheduling, runs the task waiting for the signal, and suspends the current task. For events in a multi-task system, taking the tick clock of the system as an example, the operating system is triggered to perform task scheduling, and runs tasks with high priority or timer arrival. In addition, in the case where the modified storage value is stored in the human-machine interface, a preset sound and light prompt can be executed to display a predetermined human-machine interface. In the case where the modified storage value is a variable controlled by a certain loop, the number of loop executions can be controlled or the loop can be exited. In the case where the modified storage value is a function pointer, the function function specified by the expected operation can be called to enter the predetermined application branch. In the case where the modified storage value is a register configuration value, the interface function register configuration value is modified, such as the baud rate configuration register in the asynchronous serial port peripheral function register, and the baud rate configuration register is modified to modify the baud rate of the communication interface.

[0071] Optionally, the method for controlling the application process also includes: after executing the application control process, tracking the application execution process; locating the problem of the application according to the tracking result of the application execution process, and debugging the application.

[0078] S206: The processor locates the problem of the application program according to the tracking result of the application program execution process, and debugs the application program.
