Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.
Some terms in the embodiments of the present invention are explained below to be understood by those skilled in the art.
In an embedded operating system, a bootloader program is usually started and loaded before an operating system kernel runs, and the bootloader program can be used for initializing a hardware device of an embedded device, establishing a memory space mapping diagram and the like, so that the software and hardware environment of the system of the embedded device can be in a proper state, and a correct running environment is prepared for subsequently calling the operating system kernel.
In the embodiment of the present invention, the embedded device may be provided with a user instruction window, such as a user instruction interface module, where the user instruction window may be located on the bootloader program module, or may also be located on any other module of the embedded device, and is used to enter a user-defined user instruction for instructing the bootloader program module to implement a user-defined bootloader function.
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Example one
Referring to fig. 1, the user instruction processing method provided in the embodiment of the present invention is applied to an embedded device, where the embedded device may include a bootloader program module, and an implementation process of the user instruction processing method may be described as follows:
s100: acquiring a first user instruction input by a user through a user instruction window of a bootloader program module, wherein the first user instruction is a programmable instruction of a bootloader function defined by the user;
s200: analyzing the first user instruction to obtain a bootloader functional parameter and a plurality of command codes; the bootloader function parameter is used for indicating the command execution format of each command code in the plurality of command codes;
s300: and executing a plurality of command codes based on the bootloader function parameters to realize the self-defined bootloader function.
In S100, the embedded device may obtain a first user instruction entered by a user through a user instruction window of the bootloader program module, where the entered first user instruction may be one user instruction or multiple user instructions.
When the embedded device only acquires one user instruction, the embedded device can analyze the user instruction, namely, the subsequent processing process of the first user instruction is started; when the embedded device obtains a plurality of user instructions, the embedded device may edit the plurality of user instructions into a script instruction, and then perform operations such as parsing on the script instruction.
The first user instruction may be a programmable instruction of a bootloader function defined by a user, where the programmable instruction may be an instruction that the embedded device may perform a series of operations such as logic fetching, data reading, compiling, and executing.
In practical application, assuming that a user needs to realize the bootloader function of the main image recovery in the bootloader state, the user can enter a first user instruction corresponding to the bootloader function of the main image recovery through a user instruction window of a bootloader program module; or, if the user needs the embedded device in the bootloader state, and can perform some logic judgment processing according to the running characteristics of the embedded device such as the peripheral state and then enter the system, the user can enter the first user instruction corresponding to the bootloader function judgment processing through the user instruction window of the bootloader program module; or, if the user temporarily determines that the bootloader program module needs to make a judgment for some specific events, such as General Purpose Input/Output (GPIO) tags, then strategically and actively perform selective switching of the images to switch to an environment in which the images can be run, and the user may also enter a first user instruction corresponding to the bootloader function through a user instruction window of the bootloader program module.
In other words, in the embodiment of the present invention, if a user wants to implement a certain function in the bootloader state, the user-defined bootloader function can be implemented only by entering the first user instruction corresponding to the function through the user instruction window of the bootloader program module, which solves the technical problem in the prior art that the operation process of implementing the user-defined bootloader function by the embedded device is complicated, and improves the working efficiency.
Optionally, after acquiring a first user instruction input by a user through a user instruction window of the bootloader program module, the embedded device may further perform character conversion on the first user instruction to obtain a second user instruction after the character conversion, and then the embedded device may encrypt the second user instruction based on a preset encryption rule to obtain an encrypted third user instruction, and store the third user instruction.
The first user instruction acquired by the embedded device may be an instruction in the form of a character string, and if the embedded device directly stores the first user instruction in the form of the character string, the instruction storage pressure of the embedded device may be increased. Therefore, in order to save the storage space of the embedded device or reduce the instruction storage pressure of the embedded device, after the embedded device obtains the first user instruction, the first user instruction may be subjected to character conversion, that is, the first user instruction in the form of a character string may be converted into the second user instruction in the form of a character, and the character form may be an array, a structure, or the like.
For example, if the first user instruction is "Add 1, 2", where "Add" is an addition operation, after the first user instruction is character-converted, the second user instruction may be "a, parameter 1, parameter 2", where "a" in the second user instruction may be an operation code, and the subsequent embedded device may perform operations such as storing "a, parameter 1, parameter 2". Of course, this example is merely illustrative and not intended to limit embodiments of the present invention.
Therefore, after the embedded device obtains the second user instruction after the character conversion, the second user instruction can be encrypted according to the preset encryption rule, and the encrypted third user instruction is obtained, so that the data on the hardware storage medium can not be stolen and leaked through a reverse development method.
In practical applications, the preset Encryption rule may be a preset Encryption algorithm, such as a Data Encryption Standard (DES), a Triple Data Encryption Standard (3 DES), and other symmetric Encryption algorithm algorithms; alternatively, as with asymmetric encryption algorithms, the encryption and decryption use different keys, usually two keys, "public key" and "private key"; or it may be a user-defined encryption algorithm. The process of encrypting the second user instruction by using the encryption algorithm may refer to the prior art, and is not described in detail in the embodiments of the present invention.
The embedded device may store the encrypted third user instruction, and specific storage manners may include, but are not limited to, the following two cases:
in the first case, the embedded device may store the encrypted third user instruction in a preset path file of the bootloader program module, where the preset path file may be automatically selected by the bootloader program module or may be self-defined by the user through the embedded device, and the like.
And in the second case, because part of bootloader program modules have no concept of files, in this case, the embedded device can store the encrypted third user instruction into the specified FLASH memory FLASH partition position.
After acquiring the first user instruction, the embedded device may enter S200, that is, the embedded device analyzes the first user instruction to obtain a bootloader function parameter and a plurality of command codes, where the bootloader function parameter may be used to indicate a command execution format of each command code in the plurality of command codes.
In the embodiment of the present invention, the command code may be a program code executable by the embedded device, and the bootloader function parameter may indicate a command execution format of the command code, such as a command execution format of mathematical operation, logical operation, relational operation, miscellaneous operation, and the like.
The mathematical operation may include operation rules such as addition, subtraction, multiplication, division, etc., the logical operation may include logical relationship operation rules such as and, or, and, not, etc., the relationship operation may include operation rules such as sequence, loop, condition, etc., and the miscellaneous operation may include special operation rules such as delay, jump, etc.
In practical applications, the command execution format of the command code indicated by the bootloader function parameter may include one or more of the above operations, and the embodiments of the present invention are not limited as the case may be.
Optionally, the analyzing, by the embedded device, the first user instruction to obtain the bootloader function parameter and the plurality of command codes may include:
if the embedded device encrypts the second user instruction after the character conversion according to the preset encryption rule to obtain the encrypted third user instruction, when the embedded device analyzes the user instruction, the embedded device may decrypt the encrypted third user instruction according to the preset decryption rule corresponding to the preset encryption rule to obtain the second user instruction.
The way in which the embedded device decrypts the encrypted third user instruction may include, but is not limited to, the following:
first, if the preset encryption rule adopted by the embedded device is a symmetric encryption algorithm to encrypt the third user command, the embedded device may adopt the preset decryption rule consistent with the preset encryption rule when decrypting the third user command, and if the embedded device adopts the DES encryption, the DES is also adopted when decrypting.
Secondly, if the preset encryption rule adopted by the embedded device is an asymmetric encryption algorithm, the embedded device encrypts the third user instruction by using a 'public key', and the embedded device decrypts the third user instruction by using a 'private key' corresponding to the 'public key'; third, the user can use the self-defined encryption algorithm to encrypt and decrypt the third user command. The embodiment of the present invention is not limited specifically to which encryption and decryption method is adopted.
The embedded device obtains a second user instruction after decrypting the third user instruction, and then the embedded device can analyze the second user instruction to obtain the bootloader functional parameter and the plurality of command codes.
Optionally, the executing, by the embedded device, the multiple command codes based on the bootloader function parameter may include:
executing a first command code in the plurality of command codes based on the bootloader function parameter to obtain an execution result;
if the execution result accords with the preset result, executing a second command code after the first command code in the plurality of command codes; otherwise, re-executing the first command code or giving up executing the first command code; the preset result is an expected result corresponding to the user-defined bootloader function of the first user instruction.
For example, it is assumed that the embedded device obtains a first command code after parsing the user instruction, and the bootloader function parameters corresponding to the first command code include mathematical operations, miscellaneous operations, and the like, and the expected result of executing the first command code is "input"; the bootloader function parameters corresponding to the second command code include logical operation, relational operation, etc., and the expected result of executing the second command code is "read data", etc.
Therefore, after the embedded device obtains the plurality of command codes through analysis, the embedded device can sequentially execute the plurality of command codes based on the bootloader function parameters, and realize functions that a user wants to realize, such as functions of recovering a main image and the like. If the embedded device executes the first command code, the execution process may sequentially perform mathematical operations, miscellaneous operations, and the like, and then may obtain an execution result, and if the execution result is "input", the embedded device executes the next command code, i.e., the second command code.
If the execution result is not in accordance with the expectation, assuming that the execution result is "output", obviously, the execution result is not in accordance with the "input" of the expectation result, at this time, the embedded device may judge the correctness of the first command code, that is, enter an arbitration stage, for example, the embedded device may arbitrarily input data, if the display error is detected, that is, the data cannot be input, the first command code may have an error, and at this time, the embedded device may give up executing the first command code; otherwise, if the data can be input, it indicates that the first command code may be correct, and the embedded device may re-execute the first command code.
