Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment upgrade management, and in particular to an electronic equipment program error-proof upgrade method and system. Background Art

[0002] With the advancement of technology, there are more and more types of electronic devices and their functions are becoming more and more complex. While electronic device developers are constantly improving functions, they also need to fix corresponding bugs, so they need to upgrade the programs (APPs) of electronic devices.

[0003] For the upgrade of electronic device programs, the boot that is solidified inside the chip by the original factory is traditionally used to upgrade the program (i.e., ISP upgrade). However, the upgrade protocols and methods of each chip manufacturer vary greatly, and there is no unified standard, making it difficult to achieve a unified upgrade platform. Later, the IAP upgrade method gradually became the mainstream. Since it is completely customizable, it can be used on different platforms and chips, easily realizing the platformization of program upgrades. Due to the platform design, when upgrading programs of different electronic devices or different series of the same electronic device, it is easy for the burning files to be confused and cross-burned, resulting in partial or complete unusable functions of the electronic device. In severe cases, the electronic device may be damaged. To avoid the above problems, although the error probability can be reduced through the control of APP burning files, there are still disadvantages such as large workload and the risk that cannot be completely avoided.

[0004] Therefore, how to provide a method and system for error-proof upgrading of electronic device programs to improve the reliability of upgrading electronic device programs has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a method and system for error-proofing the program upgrade of an electronic device, so as to improve the reliability of the program upgrade of the electronic device.

[0006] In a first aspect, the present invention provides a method for error-proofing an electronic device program upgrade, comprising the following steps:

[0007] Step S1, split the program upgrade package into several program sub-packages, set a start sequence code in the first program sub-package, set an end sequence code in the last program sub-package, perform hash calculation on each program sub-package to obtain a hash value, add the hash value to the end of each program sub-package, and preset the start sequence code and the end sequence code into the BootLoder program of the MCU;

[0008] Step S2: sending an upgrade instruction to the MCU of the electronic device, and the MCU switches the currently running application from the APP program to the BootLoder program based on the upgrade instruction;

[0009] Step S3, the BootLoder program obtains each program sub-package, verifies each program sub-package and stores it in FLASH;

[0010] Step S4, the BootLoder program combines the program subpackages stored in the FLASH into a program upgrade package to perform an upgrade operation, and switches to the APP program after the upgrade is completed.

[0011] Furthermore, the step S1 is specifically as follows:

[0012] The program upgrade package is split into several program subpackages, and each of the program subpackages is numbered in sequence. Based on the numbers, a starting sequence code is set in the first program subpackage, and an ending sequence code is set in the last program subpackage. Hash calculations are performed on each of the program subpackages to obtain hash values, and each hash value is added to the end of the corresponding program subpackage. The starting sequence code and the ending sequence code are preset in the BootLoder program of the MCU.

[0013] Furthermore, the step S2 is specifically as follows:

[0014] An upgrade instruction carrying a URL address for downloading the program sub-package is sent to the MCU of the electronic device, and the MCU switches the currently running application from the APP program to the BootLoder program in real time based on the upgrade instruction.

[0015] Furthermore, the step S3 is specifically as follows:

[0016] The BootLoder program sequentially obtains each program sub-package based on the URL address carried by the upgrade instruction, performs integrity check on the first program sub-package based on the hash value, performs legality check on the first program sub-package based on the preset starting sequence code, and then stores the verified first program sub-package to a designated location of the FLASH;

[0017] Then, after performing integrity check on each program sub-package in sequence based on the hash value, each of the program sub-packages is stored in a designated location of the FLASH;

[0018] After the integrity check is performed on the last program subpackage based on the hash value, the legality check is performed on the last program subpackage based on the preset end sequence code, and then the checked last program subpackage is stored in a designated location of the FLASH.

[0019] Furthermore, the step S4 is specifically as follows:

[0020] The BootLoder program combines the program subpackages stored in the FLASH into a program upgrade package based on the numbering sequence, and performs an upgrade operation on the APP program based on the program upgrade package; after the upgrade is completed, the MCU switches the currently running application from the BootLoder program to the APP program.

[0023] The application switching module is used to send an upgrade instruction to the MCU of the electronic device, and the MCU switches the currently running application from the APP program to the BootLoder program based on the upgrade instruction;

[0024] A program sub-package verification storage module is used for the BootLoder program to obtain each program sub-package, verify each program sub-package and store it in FLASH;

[0025] The program upgrade module is used for the BootLoder program to splice the program subpackages stored in the FLASH into a program upgrade package to perform the upgrade operation, and switch to the APP program after the upgrade is completed.

[0026] Furthermore, the upgrade package sub-packaging module is specifically used for:

Based on the numbers, a starting sequence code is set in the first program subpackage, and an ending sequence code is set in the last program subpackage. Hash calculations are performed on each of the program subpackages to obtain hash values, and each hash value is added to the end of the corresponding program subpackage. The starting sequence code and the ending sequence code are preset in the BootLoder program of the MCU.

[0028] Furthermore, the application switching module is specifically used for:

[0029] An upgrade instruction carrying a URL address for downloading the program sub-package is sent to the MCU of the electronic device, and the MCU switches the currently running application from the APP program to the BootLoder program in real time based on the upgrade instruction.

[0030] Furthermore, the program sub-packaging verification storage module is specifically used for:

[0031] The BootLoder program sequentially obtains each program sub-package based on the URL address carried by the upgrade instruction, performs integrity check on the first program sub-package based on the hash value, performs legality check on the first program sub-package based on the preset starting sequence code, and then stores the verified first program sub-package to a designated location of the FLASH;

[0032] Then, after performing integrity check on each program sub-package in sequence based on the hash value, each of the program sub-packages is stored in a designated location of the FLASH;

[0033] After the integrity check is performed on the last program subpackage based on the hash value, the legality check is performed on the last program subpackage based on the preset end sequence code, and then the checked last program subpackage is stored in a designated location of the FLASH.
