DETAILED DESCRIPTION

[0013] The embodiments of the present application provide an embedded application software upgrade method and device based on ARM architecture, so as to solve the problem of low efficiency of application software upgrade.

Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0015] The embedded application software upgrade method based on ARM architecture provided in the embodiment of the present application can be executed by an electronic device, or by software installed in the electronic device. Specifically, the electronic device can be a terminal device or a server device. Among them, the terminal device can include a smart phone, a laptop computer, a smart wearable device, a vehicle terminal, etc., and the server device can include an independent physical server, a server cluster composed of multiple servers, or a cloud server capable of cloud computing.

[0016] In conjunction with the accompanying drawings, an embedded application software upgrade method based on ARM architecture provided by an embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0017] Figure 1 A flow chart of an ARM architecture-based embedded application software upgrade method provided by an embodiment of the present invention is shown, and the method comprises the following steps: S102, obtaining a configuration file containing the application software to be upgraded from a mobile storage device.

[0018] The application software to be upgraded includes: application software in an embedded system based on the ARM architecture, and the configuration file includes: an encrypted software upgrade file and a step file for updating the application software to be upgraded.

[0019] A mobile storage device is a device that can read data without the assistance of other hardware or network after being inserted into an electronic device, such as a USB flash drive. The following description takes the mobile storage device as a USB flash drive as an example.

[0020] An embedded system is a system based on an Advanced RISC Machine (ARM) architecture processor, and the application software in the system has high security and flexibility, such as Linux embedded systems.

[0021] The configuration file is stored in a U disk, including an encrypted software upgrade file and a step file. Specifically, the software upgrade file is a compressed package used to upgrade the application software to be upgraded. By encrypting it, the security of upgrading the application software to be upgraded can be improved; the step file is used to update the application software to be upgraded, including executing the installation package of the program to update the application software to be upgraded.

[0022] It should be noted that a U disk may include one or more configuration files for upgrading corresponding multiple application software to be upgraded in the embedded system.

[0023] S104, identifying the configuration file in the mobile storage device based on the software naming information of the application software to be upgraded and the file naming information of the configuration file in the mobile storage device.

[0024] The software naming information includes the manually input application program information corresponding to the application software to be upgraded.

[0025] The file naming information includes the folder name of the configuration file, such as the manufacturer code, version number, and the date when the configuration file was last updated.

[0026] According to the software naming information of the application software to be upgraded and the file naming information of the configuration file in the mobile storage device, the configuration file corresponding to the application software to be upgraded in the mobile storage device is identified. Specifically, the consistency of the software naming information of the application software to be upgraded and the file naming information of the configuration file is determined.

[0027] S106, when the software naming information of the application software to be upgraded is consistent with the file naming information of the configuration file, the corresponding software upgrade file is executed according to the step file in the configuration file to upgrade the application software to be upgraded.

[0028] When the software naming information of the application software to be upgraded is consistent with the file naming information of the configuration file, it means that the file content in the configuration file can be upgraded and updated for the application software to be upgraded. According to the step file included in the configuration file of the mobile storage device, the corresponding encrypted software upgrade file is executed according to the steps of updating the application software to be upgraded. After the corresponding software upgrade file is executed according to the steps in the step file, the application software to be upgraded can be replaced with the software upgrade file, that is, the application software to be upgraded is upgraded and updated according to the latest configuration in the software upgrade file.

[0029] By adopting the technical solution of the embodiment of the present application, a configuration file containing the application software to be upgraded in a mobile storage device is obtained, the application software to be upgraded includes: the application software in the embedded system based on the ARM architecture, the configuration file includes: the encrypted software upgrade file and the step file for updating the application software to be upgraded; based on the software naming information of the application software to be upgraded and the file naming information of the configuration file in the mobile storage device, the configuration file in the mobile storage device is identified; when the software naming information of the application software to be upgraded is consistent with the file naming information of the configuration file, the corresponding software upgrade file is executed according to the step file in the configuration file to upgrade the application software to be upgraded. It can be seen that in the process of upgrading the application software, the configuration file in the mobile storage device is obtained, and when it is identified that the software naming information of the application software to be upgraded is consistent with the file naming information of the configuration file, the software upgrade file is executed using the step file in the configuration file to upgrade the application software to be upgraded, without the need for additional upgrade tools or remote upgrade through the network, the application software in the embedded system can be directly upgraded using a portable and mobile mobile storage device, thereby improving the efficiency of application software upgrade.

[0030] In one embodiment, based on the software naming information of the application software to be upgraded and the file naming information of the configuration file in the mobile storage device, the configuration file in the mobile storage device is identified (ie, S104), and the following steps A1-A3 may be performed: Step A1: When the configuration file contains an update flag, the mobile storage device is mounted to a designated directory.

[0031] The specified directory is used to temporarily store and display the file contents in the removable storage device in the embedded system.

[0032] After the electronic device is powered on by connecting to the power supply voltage, that is, after the system is powered on, before starting the application corresponding to the application software to be upgraded, a boot program is first started. The boot program is used to identify whether a USB flash drive is inserted into the electronic device. When the USB flash drive is inserted, the USB flash drive is read to see whether there is an update mark, wherein the update mark can be a file with an update mark, such as a file with an update mark included in the configuration file of the USB flash drive, or the update mark can be displayed in the file naming information of the configuration file. The update mark is used to prompt the user that there is a software upgrade file corresponding to the updated application software to be upgraded in the configuration file. If there is a file with an update mark in the configuration file, it means that there is a software upgrade file corresponding to the updated application software in the USB flash drive. According to the update mark, it can also be determined whether the content to be updated in the configuration file is manually updated or automatically updated.

[0033] When the configuration file contains an update flag, the boot program will execute the boot menu program for subsequent updates and upgrades of the application.

[0034] The U disk is rechecked through the startup menu program in the embedded system, including checking the name of the configuration file in the U disk, judging whether there is an update mark in the configuration file, and mounting the mobile storage device to the specified directory.

[0035] If the boot program does not recognize the U disk or there is no file corresponding to the update mark in the U disk, the update operation will not be performed, and the application corresponding to the original application software to be upgraded will continue to be executed.

[0036] Step A2: obtaining file naming information of the configuration file in the mobile storage device and corresponding software naming information of the application software to be upgraded.

[0037] The file naming information includes: one or more of the first manufacturer code, the first version number and the first date corresponding to the configuration file; the software naming information includes: one or more of the second manufacturer code, the second version number and the second date corresponding to the application software to be upgraded.

[0038] By starting the menu program in step A1, the file naming information of the configuration file in the mobile storage device is obtained, and the software naming information of the corresponding application software to be upgraded in the embedded system can be directly obtained.

[0039] Specifically, first, one or more of the first manufacturer code, the first version number and the first date in the file naming information of the configuration file is obtained; secondly, the software naming information of the corresponding application software to be upgraded in the embedded system can be directly obtained, and the user can also be reminded to enter one or more of the corresponding second manufacturer code, the second version number and the second date of the application software to be upgraded.

[0040] Step A3: identifying, according to the software naming information, a configuration file corresponding to the file naming information related to the software naming information in the mobile storage device.

[0041] Specifically, the software naming information of the application software to be upgraded in the embedded system is matched with the file naming information in the configuration file in the U disk, and the configuration file related to the software naming information can be identified, such as identifying that the file naming information of the configuration file is consistent with one or more of the software naming information. However, only when the matching of the three information in the naming information is passed, will the update thread be entered. The three matchings include: the first manufacturer code and the second manufacturer code, the first version number and the second version number, and the first date and the second date. Only the configuration file that is consistent with the three can be used to update the corresponding application software to be upgraded.

[0042] In this embodiment, by determining whether there is an update mark in the configuration file in the mobile storage device, the mobile storage device is mounted to a specified directory, and the file naming information of the configuration file and the software naming information of the application software to be upgraded in the system are obtained, and the configuration file in the mobile storage device is determined according to the software naming information. The system can automatically determine whether there is an update mark in the mobile storage device, and can identify the configuration file corresponding to the application software to be upgraded according to the obtained software naming information and file naming information.

[0043] In one embodiment, when the configuration file includes an update flag, before mounting the mobile storage device to the specified directory (ie, step A1), the following step B may be performed: Step B: determining whether the software upgrade file in the configuration file is updated according to the update flag; if the software upgrade file is updated, determining an update method for the configuration file, the update method including manual update or automatic update.

[0044] After the embedded system is started, the boot program reads whether there is a file corresponding to the update mark in the U disk. The file corresponding to the update mark can be a file with an update mark in the configuration file of the U disk. The update mark can include the text "updated" or a color mark, etc., which is not limited here.

[0045] According to the update flag, it is determined whether there is update content in the configuration file, and the update content includes: updates made by the software upgrade file, and may also include updates made by the step file, etc. If the software upgrade file has been updated, it can also be determined whether the update operation performed by the configuration file is based on manual update or automatic update, such as setting a manual update or automatic update identification option in the file corresponding to the update flag.

[0046] As an example, when the embedded system corresponding to the application software to be upgraded is used by developers to update and debug, the startup menu program in the system can automatically update the application software to be upgraded, without entering the software naming information, and automatically upgrade the application software to be upgraded according to the steps in the configuration file. If it is during the use of the product, it is more appropriate to use manual update, and different versions of configuration files in the U disk can be selected according to the software naming information of the application software to be upgraded, and the application software to be upgraded can be upgraded.

[0047] In this embodiment, an update flag is used to determine whether there is updated content in the U disk, and to determine the update method of the application in the updated embedded system. According to different judgment results, different processes for updating the application corresponding to the application software to be upgraded are automatically executed. There is no need to manually stop updating the application or start updating the application, which can save operating steps.

[0048] In one embodiment, when the software naming information of the application software to be upgraded is consistent with the file naming information of the configuration file, the corresponding software upgrade file is executed according to the step file in the configuration file (ie, S106), and the following steps C1-C2 may also be executed: Step C1, perform consistency identification on the application software to be upgraded and the corresponding configuration file. When the software naming information of the application software to be upgraded is consistent with the file naming information of the configuration file, decrypt the encrypted software upgrade file corresponding to the application software to be upgraded in the configuration file according to the update thread in the step file in the configuration file to obtain the decrypted software upgrade file.

[0049] The decryption process includes: decrypting the software upgrade file according to the decryption password generated by the file naming information.

[0050] By performing consistency identification on the application software to be upgraded and the corresponding configuration file, when the software naming information of the application software to be upgraded is consistent with the file naming information of the configuration file, that is, the first manufacturer code and the second manufacturer code, the first version number and the second version number, and the first date and the second date are all consistent, the configuration file is used to update and upgrade the application software to be upgraded.

[0051] An update thread is the smallest unit that the operating system can schedule operations on. Each update thread can execute different update tasks in parallel.

[0052] Specifically, the startup menu program in the embedded system will identify the first line of the step file in the configuration file, and the first line instructs the embedded system to start the update operation and enter the update thread; after entering the update thread, the second line in the step file is identified, and the second line is used to check whether the version of the application corresponding to the software upgrade file in the configuration file is suitable for this system. If it is not suitable for this system, the update operation is terminated and an error prompt word is returned; if it is suitable for this embedded system, the third line in the step file is continued to be identified, and the second line is used to instruct to copy the software upgrade file in the configuration file to the embedded system. If an error occurs during the copying process, the update operation is terminated and an error prompt word is returned; if the copy is successful, the fourth line in the step file is continued to be identified, and the fourth line is used to instruct to decrypt the encrypted software upgrade file corresponding to the application software to be upgraded to obtain the decrypted software upgrade file. If the decryption fails, the update operation is terminated and an error prompt word is returned.

[0053] Among them, according to the file naming information, a decryption password is generated according to the encryption password generation rule to decrypt the software upgrade file.

[0054] Step C2, deleting the original program file in the embedded system, and moving the decrypted software upgrade file into the target program directory.

[0055] If the decryption is successful, the decrypted software upgrade file is obtained, and the fifth line in the step file is continued to be identified. The fifth line indicates to delete the original program file in the embedded system. The original program file is the program file related to the application software to be updated. If the deletion fails, the update operation is terminated and an error prompt word is returned; then the sixth line in the step file is identified. The sixth line is used to indicate that the decrypted software upgrade file is moved to the target program directory.

[0056] In this embodiment, when the application software to be upgraded is consistent with the corresponding configuration file, the corresponding update steps are executed in sequence according to the update thread included in the step file in the configuration file, and finally the encrypted software upgrade file is decrypted and the decrypted software upgrade file is moved into the target program directory. This can improve the speed of upgrading the application software, avoid the need for complex network configuration and physical connection, and make the application software upgrade process in the embedded system more efficient.

[0057] In one embodiment, after the decrypted software upgrade file is moved into the target program directory (i.e., step C2), the following steps D1-D2 may be performed: Step D1, decompressing the decrypted software upgrade file to obtain a decompressed software upgrade file.

[0058] According to step C1, the decrypted software upgrade file can be moved into the target program directory, and the seventh line in the step file is continuously identified. The seventh line is used to instruct to decompress the compressed package of the decrypted software upgrade file to obtain the decompressed software upgrade file.

[0059] Step D2, performing integrity check on the decompressed software upgrade file to obtain the software upgrade file after integrity check.

[0060] According to step D1, continue to identify the seventh line in the step file. The seventh line is also used to indicate that the decompressed software upgrade file will be subjected to integrity verification. The final result of the step file execution is to obtain the software upgrade file after the integrity verification, and the software upgrade file after the integrity verification in the target program directory can update the application software to be upgraded.

[0061] Integrity check specifically refers to the system's startup menu program performing a Message-Digest Algorithm 5 (md5) check on the decompressed software upgrade file. The md5 check can perform a hash operation on the data in the received decompressed software upgrade file to check the correctness of the corresponding data and ensure the integrity of the software upgrade file after the update process.

[0062] In this embodiment, by decompressing the decrypted software upgrade file and performing integrity verification on the decompressed software upgrade file, an integrity verification mechanism is provided to ensure that the software upgrade file obtained after the integrity verification does not have any missing content problem.

[0063] In one embodiment, the configuration file containing the application software to be upgraded in the mobile storage device is obtained (ie, S102), and the following step E may be performed: Step E: after starting the embedded system, obtaining data in the mobile storage device, the data including the configuration file of the application software to be upgraded.

[0064] Among them, the configuration file includes: the encrypted software upgrade file and step file corresponding to the application software to be upgraded; the software upgrade file includes: compressing the software upgrade file with a hash value table to obtain a compressed package, and determining the compressed package as the software upgrade file; the step file includes: a file of an update thread with virtual instructions.

[0065] After the embedded system is started, data in the mobile storage device can be obtained, and the data includes configuration files of the application software to be upgraded, and may also include data contained in other mobile storage devices.

[0066] Specifically, the configuration file in the mobile storage device includes a software upgrade file and a step file. The production process of the mobile storage device includes: first, placing the corresponding content of the completed application software to be updated in the folder of the software upgrade file to be performed, generating an MD5 hash value table for all files in the folder through the Md5sum command, and using the command: md5sdum*>md5sum.txt to pack and compress all files in the folder into a compressed package to generate a software upgrade file in the form of a compressed package. Among them, the Md5sum command is a command line interface shell command under Linux, which is used to calculate and verify the MD5 checksum.

[0067] Secondly, encrypt the software upgrade file. The encryption process includes: executing the script encrypt.sh, which uses the open source software library package openssl tool to encrypt the compressed package of the application, that is, the software upgrade file. The encryption process is as follows: the encryption command is: . / openssl des3-pbkdf2-iter 10000-salt-in $1-out $2-pass pass:$3, where: . / openssl: A command line tool for executing OpenSSL commands. des3: Used to specify the use of symmetric encryption algorithms (Triple DES, DESede) for encryption. -pbkdf2: Specifies the use of a pseudo-random function to derive the key using the PBKDF2 algorithm. -iter 10000: Specifies the number of iterations of the PBKDF2 algorithm, which is 10,000 here. -salt: Specifies the generation of a random salt value to increase the complexity of key derivation. -in $1: Specifies the input file, $1 is a variable, usually used in scripts, representing the first command line parameter. -out $2: Specifies the output file, $2 is a variable, representing the second command line parameter. -pass pass:$3: Specifies the password, $3 is a variable, representing the third command line parameter. Pass: The prefix indicates that the password follows.

[0068] The parameters passed in are: $1, the file name of the application compression package; $2, the file naming information of the encrypted configuration file; $3, the encryption password.

[0069] Then, add a step file for performing the update operation to the U disk data. The startup menu program in the system reads the content of the step file and performs the update operation according to the steps in the step file to update the application software to be upgraded in the embedded system. Each line in the step file is a step. For example, the step file consists of the command prompt cmd, the first parameter or the first replacement parameter value arg1, the second parameter or the second replacement parameter value arg2, etc., separated by space characters, for example: [BEG] [BEG]MMIType [UPF] Update.f MMIPath [DEC]update.f updatefile[DEL] MMI [TXF]Updatefile MMIPath .

[0070] The commands in [] are virtual commands, which are all three capital letters. The startup menu program in the embedded system recognizes these virtual commands and converts them into actual execution commands to process files and update and upgrade applications.

[0071] The description of each virtual command is as follows: [BEG] is the start command, and the first line of the update step file is this command. is the end command, and the last line of the update step file is this command, which is also the sign of the end of the update step. [UPF] is the copy command, and this virtual command will be replaced by the "cp-f" command, which is used to copy the contents of the USB flash drive to the system. [DEC] is the decryption command, and this virtual command will be replaced by the "shdecrypt.sh" command, which is used to decrypt the encrypted application file, i.e., the software upgrade file. [DEL] is the delete command, and this virtual command will be replaced by the "rm -rf" command, which is used to delete the corresponding file content. [TXF] is the decompression command, and this virtual command will be replaced by the "tar -zxf" command, which is used to decompress the application file to the specified directory.

[0072] There are other virtual commands, such as [EXE] for executing Linux instructions, [RUN] for executing scripts, [UKN] for upgrading the kernel, and [URF] for upgrading the root file system rootfs.

[0073] Finally, put the encrypted software upgrade file and step file in the configuration file, name the configuration file according to the preset format, and the preset format of the configuration file folder name can be the manufacturer code [Vendor]_version number [Version]_update date [Date]_update flag update, and the three names in [] are used as flags for the startup menu program to determine whether the application matches. Finally, copy the configuration file to the U disk, and add the file with the update flag to the U disk, and the steps of making the U disk are completed.

[0074] In this embodiment, by compressing the software upgrade file in the mobile storage device and encrypting the compressed software upgrade file using the openssl tool, an encrypted software upgrade file is obtained, so that the password of the encrypted software upgrade file will not be displayed in the USB flash drive. Since each version is different, the encryption password for each update is also different, which can ensure the security of the updated configuration file.

[0075] In one embodiment, after executing the corresponding software upgrade file (ie, S106) according to the step file in the configuration file, the following steps F1-F2 may be executed: Step F1, displaying the update progress of the application software to be upgraded in the startup menu of the embedded system, and when the update is successful, displaying a prompt word indicating the success of the update in the startup menu.

[0076] Specifically, when executing each step corresponding to the above step file, the startup menu program corresponding to the startup menu of the embedded system will print the corresponding prompt words of the update progress. For example, after the update is successful, the startup menu of the embedded system will prompt a prompt word such as "Update successful, please unplug the USB flash drive and restart the system". When the USB flash drive is removed and the entire system is restarted, the application software to be upgraded is upgraded.

[0077] Step F2: When the update fails, a progress prompt indicating the update failure is displayed in the startup menu.

[0078] When the update fails, as an example, if the update thread of the step file in the configuration file fails, the corresponding return value will be returned, and the embedded system will print the corresponding error content according to the return value, including: incorrect update folder, too old version to update, external storage device not ready, insufficient disk space, decompression error, decryption error, version error, update file does not match the system, and more than ten other progress prompts for update failure.

[0079] In this embodiment, the errors and progress of the application software to be upgraded are displayed through the startup menu page of the embedded system, so that the user can always understand the progress of the application software upgrade and can also adjust the problem easily.

[0080] In one embodiment, Figure 2The figure shows a schematic diagram of the software upgrade process of an embedded application software upgrade method based on the ARM architecture provided in an embodiment of the present application.
