Description

Technical Field

[0001] This invention relates to the field of equipment upgrade technology, and in particular to a method, apparatus, device, and medium for improving the efficiency of terminal firmware upgrades. Background Technology

[0002] The terminal security MCU program adopts a "boot (bootloader) + app (application program)" framework design. During production, to ensure efficiency and control costs, the terminal security MCU program is packaged into a unified program package, combining the "boot" and "app" components. Subsequent production lines only need to flash this package once, achieving the dual goals of increased efficiency and reduced costs. If the bootloader and app were flashed separately, dedicated workstations would be required. This would disrupt the continuity of the existing production process, directly impacting overall efficiency, and would also increase production costs due to the added workstations and steps.

[0003] like Figure 1 As shown, currently, after the terminal security MCU powers on, the ROM program verifies the packaged data. If the verification is successful, it jumps to boot, then boots to verify the app, and if successful, jumps to run the app. However, due to changes in customer requirements and program bugs, the app needs to be upgraded frequently, and each upgrade requires both booting and app repackaging, which severely impacts the terminal's upgrade efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a method, apparatus, equipment and medium for improving the efficiency of terminal firmware upgrades. Without adjusting the original production line, the firmware upgrade is changed from the original package boot+app method to app-only upgrade, which greatly improves the upgrade efficiency.

[0005] In a first aspect, the present invention provides a method for improving the efficiency of terminal firmware upgrades, comprising: Partitioning process: Divide the storage into partitions on the MCU, including an information area, a boot area, and an app area; Verification and testing process: After the MCU finishes burning the packaged data and powers on, the packaged data is verified. If the verification is successful, the boot process is initiated. The boot process reads the firmware information from the app area and performs app verification. If the verification is successful, the information area is then checked. Information area update process: Determine whether the length of the information area packet data exceeds the size of the BOOT partition. If it does, update the information area data so that the ROM only needs to verify the BOOT partition.

[0006] Furthermore, the adjustment of the information area data specifically includes changing the information area data generated by the boot+app package data to the information area data generated only by the boot partition data.

[0007] Furthermore, the information area update process also includes: after the information area data is successfully updated and the app verification is successful, the user is redirected to the app.

[0008] Furthermore, it also includes: Upgrade process: The upgrade package has been changed from updating the original boot+app package to updating only the app.

[0009] Secondly, the present invention provides an apparatus for improving the efficiency of terminal firmware upgrades, comprising: The partitioning module is used to divide the storage into partitions on the MCU, including an information area, a boot area, and an app area; The verification and detection module is used to verify the packaged data after the MCU has finished burning the packaged data and powered on. If the verification is successful, it will jump to the boot section. The boot section reads the firmware information in the app area to perform app verification. If the verification is successful, it will check the information area. The information area update module is used to determine whether the length of the information area packet data exceeds the size of the BOOT partition. If it does, the information area data is updated so that the ROM only needs to verify the BOOT partition.

[0010] Furthermore, the information area update module specifically includes adjusting the information area data by changing the information area data generated from the boot+app package data to the information area data generated only from the boot partition data.

[0011] Furthermore, the information area update module is also used to: after the information area data is successfully updated and the app verification is successful, redirect to the app.

[0012] Furthermore, it also includes: an upgrade module, where the upgrade package has been changed from the original boot+app package to only update the app.

[0013] Thirdly, the present invention provides an electronic device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the method described in the first aspect.

[0014] Fourthly, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the method described in the first aspect.

[0015] The technical solutions provided in the embodiments of the present invention have at least the following technical effects: By adjusting the data generation method from boot+app package to only boot package data, subsequent ROMs only need to verify the BOOT partition, without needing to consider the app partition. Firmware upgrades are thus changed from the original boot+app package method to app-only upgrades, significantly improving upgrade efficiency. This has been tested and verified in products, proving its feasibility, reducing production costs, and improving firmware upgrade efficiency.

[0016] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and in order to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below.

Detailed Implementation

[0019] This application provides a method, apparatus, device, and medium to improve the efficiency of terminal firmware upgrades, changing the original boot+app package upgrade method to app-only upgrades, thus greatly improving upgrade efficiency.

[0020] The overall concept of the technical solution in this application is as follows: Without setting up separate dedicated workstations, and only performing a one-time flashing of the boot+app combined program package, by adjusting and updating the information area data generated by the boot+app combination package of the terminal security MCU to only generate information area data of the boot package, subsequent ROMs only need to verify the boot partition, without needing to verify the app partition. Thus, firmware upgrades are changed from the original combination package boot+app method to only app upgrades, thereby improving upgrade efficiency. Example 1

[0021] This embodiment provides a method to improve the efficiency of terminal firmware upgrades, such as... Figure 2 As shown, it includes: S1. Partitioning process: Divide the storage into partitions on the MCU, including the information area, boot area and app area; S2. Verification and detection process: After the MCU finishes burning the package data and powers on for the first time, the package data is verified. If the verification is successful, the boot process is initiated. The boot process reads the firmware information in the app area to perform app verification. If the verification is successful, the information area is checked. S3. Information Area Update Process: Determine if the length of the information area packaged data exceeds the size of the BOOT partition. If it does, update the information area data, adjusting the information area data generated from the boot+app packaged data to information area data generated only from the boot partition data, so that the ROM only needs to verify the BOOT partition. After the information area data update is successful and the app verification is successful, jump to the app.

[0022] When upgrading the terminal security MCU via APP, the upgrade process will also be improved by changing the upgrade package from a boot + app package update to an app update only, thus improving upgrade efficiency.

[0023] In one specific embodiment, such as Figure 3 As shown, the implementation process is as follows: 1) Storage partitioning on the terminal security MCU: Information area, boot area, and app area: Information area: Includes information such as packet hash verification value and packet data length, which is written by the flashing tool after the packet data has been flashed; boot area: boot program and reserved space; App section: App firmware information + app program and reserved space.

[0024] 2) After the terminal security MCU is programmed and powered on for the first time, the ROM will verify the data packet. If the verification is successful, it will jump to the boot process.

[0025] 3) The boot process reads the firmware information from the app area for verification. If the verification is successful, the information area is checked.

[0026] 4) If the length of the information area package data exceeds the size of the boot partition, the information area data will be adjusted. The information area data generated by the boot + app package data will be changed to the information area data generated by only the boot partition data. Then, the information area containing only boot data will be written into the information area. In this way, the ROM will only need to verify the BOOT partition and will not need to care about the app partition.

[0027] On the production line, the data downloaded via toolkit will initially exceed the boot partition size in the information area. After the information area is adjusted and updated, it will not exceed the boot partition size, and no further adjustment is needed.

[0028] 5) After the information area is successfully updated and the app is successfully verified, the user will be redirected to the app.

[0029] The firmware upgrade method described above has been changed from the original boot + app package method to support app-only upgrades, greatly improving upgrade efficiency.

[0030] Based on the same inventive concept, this application also provides an apparatus corresponding to the method in Embodiment 1, as detailed in Embodiment 2. Example 2

[0031] This embodiment provides a device for improving the efficiency of terminal firmware upgrades, such as... Figure 4 As shown, it includes: The partitioning module is used to divide the storage into partitions on the MCU, including an information area, a boot area, and an app area; The verification and detection module is used to verify the packaged data after the MCU has finished burning the packaged data and powered on. If the verification is successful, it will jump to the boot section. The boot section reads the firmware information in the app area to perform app verification. If the verification is successful, it will check the information area. The information area update module is used to determine whether the length of the information area packet data exceeds the size of the BOOT partition. If it does, the information area data is updated so that the ROM only needs to verify the BOOT partition.

[0032] Specifically, the information area update module adjusts the information area data by changing the information area data generated from the boot+app package data to information area data generated only from the boot partition data.

[0033] Specifically, the information area update module is also used to: after the information area data is successfully updated and the app verification is successful, redirect to the app.
