[0001] This invention relates to the field of data processing technology, and in particular to a method, apparatus, electronic device, and storage medium for upgrading applications from controllers. Background Technology

[0002] The controller is used to implement the system's control functions. It controls the voltage or current in the circuit by changing the connection state of the main circuit according to a predetermined sequence, or by changing the resistance value of the resistors in the circuit, to achieve operations such as system startup, operation, and shutdown. It can consist of a program counter, instruction register, instruction decoder, timing generator, and operation controller, coordinating and directing the entire system to achieve specific functions under program control. The controller includes a master controller and slave controllers. In the automotive industry, the integration strategy between master and slave controllers is widely used. Controller applications are frequently upgraded and replaced, and there are situations where master controllers from different manufacturers are matched with slave controllers from different manufacturers. Since traditional corresponding upgrade methods are only applicable to single-component upgrades, this not only places high demands on application version management at the manufacturing and after-sales ends, but also cannot be compatible with slave controllers from multiple manufacturers. Therefore, solving the problem of application upgrade matching between master and slave controllers is crucial. Summary of the Invention

[0010] The address offset module is used to determine the target offset starting address corresponding to the target upgrade package if it does not exist, and update the target starting address of the target upgrade package to the target offset starting address.

[0011] The upgrade module is used to obtain the target upgrade package through the main controller and write the target upgrade package into the slave controller.

[0012] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0013] At least one processor; and

[0014] A memory communicatively connected to the at least one processor; wherein,

[0015] The memory stores a computer program that can be executed by the at least one processor, which enables the at least one processor to perform the application upgrade method for the controller as described in any embodiment of the present invention.

[0016] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the application upgrade method of the controller as described in any embodiment of the present invention.

[0017] The technical solution of this invention involves determining the target starting address of the target upgrade package from the target controller; then determining whether the target starting address exists within the target address range of the main controller; if not, determining the target offset starting address corresponding to the target upgrade package from the target upgrade file, and updating the target starting address of the target upgrade package to the target offset starting address; wherein, the target upgrade file includes the association between the upgrade package and the offset starting address; finally, obtaining the target upgrade package through the main controller and writing the target upgrade package into the slave controller.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0026] Example 1

[0027] Figure 1This is a flowchart of an application upgrade method for a slave controller provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where applications on a slave controller are being upgraded. This method can be executed by an application upgrade device for the slave controller, which can be implemented in hardware and / or software. This application upgrade device can be configured in an electronic device that has an application upgrade method for the slave controller. Figure 1 As shown, the method includes:

[0028] S110. Determine the target start address of the target upgrade package from the target controller, and determine whether the target start address exists within the target address range of the main controller.

[0029] The target address range can be any range of addresses that the master controller allows the upgrade package from the controller to pass through.

[0030] Specifically, the interaction method between the master controller and the slave controller is as follows: Figure 2 As shown, the main controller is the only interface between the system and external programs. Upgrading the slave controllers requires forwarding the data from the main controller to the slave controller. In actual system operation, considering the platformization of the same system and the risks associated with component resources, there are situations where multiple manufacturers' main controllers are matched with multiple manufacturers' slave controllers, resulting in... Figure 2 The risk that some components formed by multiple combinations of controllers may not be compatible with the master controller may prevent the application of the slave controller from being upgraded normally.

[0031] For example, taking an assisted driving control system as an example, it contains a main controller node: a smart forward-looking camera, and a slave controller node: a millimeter-wave radar. When the millimeter-wave radar application needs to be upgraded, the smart forward-looking camera needs to send an upgrade package to the millimeter-wave radar. However, because the application start address of millimeter-wave radars from different manufacturers is not within the range of the smart forward-looking camera, the smart forward-looking camera may fail to send the upgrade package to the millimeter-wave radar, resulting in the failure of the millimeter-wave radar application upgrade.

[0032] Therefore, after determining the target start address of the target upgrade package from the target controller, this application needs to accurately determine whether the target start address is within the target address range of the main controller, and then adjust the target start address of the target upgrade package according to the determination result to ensure that the upgrade package can be safely written from the main controller to the slave controller.

[0033] In one feasible embodiment, optionally, before determining whether the target starting address exists within the target address range of the main controller, the method further includes:

[0034] Obtain the allowed write address range for different object main controllers;

[0035] Take the intersection of the allowed write address ranges as the target address range for main control.

[0036] Specifically, because the permissible write address ranges of different object master controllers are different, if only the permissible write address range of one master controller is used as the target address range, even if the target start address of the target upgrade package of the slave controller is adjusted according to the permissible write address range, there may still be a situation where it does not match another master controller. Therefore, it is necessary to obtain the permissible write address range of all existing different object master controllers, that is, the target address range. So, it is necessary to take the intersection of the permissible write address ranges of different object master controllers. In this way, this intersection can represent the permissible write address range of all master controllers, and it can be used as the target address range of the master controller.

[0037] For example, the allowed write address range for main controller 1 is 0x00000000-0x01FFFFFF; the allowed write address range for main controller 2 is 0x00F00000-0x02000000. Extracting the intersection of the allowed write address ranges of the main controllers, we get 0x00F00000-0x01FFFFFF. Therefore, 0x00F00000-0x01FFFFFF is the target address range of the main controller.

[0038] This technical solution achieves consistency in the allowed write address ranges of master controllers by taking the intersection of the allowed write address ranges of different object master controllers and using it as the target address range of the master controller. This allows the start address of the upgrade package for the slave controller to be adjusted according to the target address range, making it suitable for all master controllers and more conducive to the application upgrade of slave controllers.

[0039] S120. If it does not exist, determine the target offset start address corresponding to the target upgrade package, and update the target start address of the target upgrade package to the target offset start address.

[0040] The target offset starting address can be a starting address that fits the target address range.

[0041] Specifically, the target start address of the target upgrade package is obtained from the target controller. If the target start address does not exist within the target address range of the main controller, it means that if the target upgrade package continues to be written to the main controller using the target start address, the main controller will not be able to recognize the target upgrade package. Therefore, the target start address of the target upgrade package needs to be updated to the target offset start address to fit the target address range. If the target start address exists within the target address range of the main controller, the target upgrade package is obtained through the main controller and then written to the slave controller.

[0042] Optionally, one feasible way to determine the target offset starting address corresponding to the target upgrade package is to determine the target offset starting address corresponding to the target upgrade package from the target upgrade file. The target upgrade file can be a file that records the relationship between the target upgrade package, the target starting address, and the target offset starting address. The target upgrade file includes the association between the upgrade package and the offset starting address.

[0043] In one feasible embodiment, optionally, the process of determining the target upgrade file includes steps A1-A4:

[0044] Step A1: Obtain the starting address of the upgrade package from the controller for different objects.

[0045] Step A2: Determine if the starting address of each upgrade package from the controller is within the target address range.

[0046] Step A3: If it exists, store it directly in the target upgrade file.

[0047] Step A4: If it does not exist, the starting address of the controller upgrade package will be offset to the target address range as the offset starting address, and the correspondence between the starting address and the offset starting address will be established and stored in the target upgrade file.

[0048] Specifically, because different production objects exist within a single controller, the starting addresses of the corresponding upgrade packages will also differ. Furthermore, the starting address may not necessarily be within the target address range; that is, the master controller might not be able to recognize the upgrade package from a single controller. Therefore, it is necessary to determine whether the starting address of each upgrade package from a single controller exists within the target address range. If it does, it means that the upgrade package from this single controller can be recognized by the master controller, and the starting address of the upgrade package from the single controller needs to be stored in the target upgrade file. If it does not exist, it means that the upgrade package from this single controller cannot be recognized by the master controller, and the starting address of the upgrade package from the single controller needs to be offset to the target address range as the offset starting address. Simultaneously, a correspondence between the starting address and the offset starting address is established and stored in the target upgrade file. By traversing all single controllers, an accurate target upgrade file can be created, making it easy to find the offset address corresponding to the starting address of the upgrade package from the single controller by querying the target upgrade file later.

[0049] For example, referring to Table 1, the target address range of the master controller is 0x00F00000-0x01FFFFFF. The starting address of slave controller 1 is 0x00100000; the starting address of slave controller 2 is 0x00110000; and the starting address of slave controller 3 is 0x00120000. It can be seen that the starting addresses of these three slave controllers are not within the target address range. Therefore, the starting addresses need to be offset. For example, the starting address offset of slave controller 1 in Table 1 is 0x00FC8000. Then, the starting address and / or the offset starting address are stored in the target upgrade file to create an accurate target upgrade file.

[0050] Table 1

[0051] From controller 1: 0x00100000 From controller 1: 0x00FC8000 From controller 2: 0x00110000 From controller 2: 0x00100000 From controller 3: 0x00120000 From controller 3: 0x00FE0000

[0052] This technical solution accurately creates the target upgrade file by determining whether the starting address of each upgrade package for the controller falls within the target address range. This facilitates the accurate determination of the offset address corresponding to the starting address of the upgrade package for the controller via the target upgrade file. Furthermore, the target upgrade file can be provided to production and after-sales departments to facilitate application upgrades for the controller.

[0053] S130. Obtain the target upgrade package through the main controller and flash the target upgrade package into the slave controller.

[0054] Specifically, the acquired target upgrade package can be recognized by the main controller, meaning the main controller can write the target upgrade package into the slave controller.

[0055] Optionally, to ensure the accuracy of the target upgrade package flashed to the slave controller, it is necessary to determine whether the starting address of the target upgrade package received by the target slave controller matches the target starting address or the target offset starting address. If it matches, it means that the target upgrade package can be used to upgrade the application of the slave controller, and the application of the target slave controller is upgraded according to the target upgrade package. If it does not match, it means that although the target upgrade package may be recognized by the master controller, it does not meet the requirements for upgrading the application of the slave controller, and the flashing failure is reported to ensure that the target upgrade package flashed to the slave controller is accurate.

[0056] Optionally, different vendor codes, different upgrade package address ranges, and different security access algorithms can be used to differentiate between master and slave controllers of different objects, further ensuring the accuracy of the upgrade.

[0057] Optionally, after receiving the target upgrade package from the master controller, the slave controller needs to determine the starting address of the target upgrade package. If the starting address of the target upgrade package is the target offset starting address, then the starting address of the target upgrade package needs to be offset back to the target starting address to satisfy the slave controller's preset starting address; the preset starting address is the target starting address, thus ensuring accurate application upgrades to the slave controller. Alternatively, an address verification can be performed on the offset target starting address. If the address is accurate, the application upgrade can then be performed based on the target upgrade package to ensure the accuracy of the offset target starting address and prevent the slave controller from crashing. If the offset target starting address is inaccurate, a flashing failure message should be immediately returned.

[0058] Optionally, if the flashing of the target upgrade package to the slave controller fails due to an abnormal power outage, the application on the target slave controller can be upgraded again after power is restored, based on the target upgrade package. This avoids repeating the process of flashing the target upgrade package from the master controller to the slave controller, ensuring the stability of the controller upgrade and saving flashing time.

[0059] The technical solution of this invention involves determining the target starting address of the target upgrade package from the target controller; then determining whether the target starting address exists within the target address range of the main controller; if not, determining the target offset starting address corresponding to the target upgrade package from the target upgrade file, and updating the target starting address of the target upgrade package to the target offset starting address; wherein, the target upgrade file includes the association between the upgrade package and the offset starting address; finally, obtaining the target upgrade package through the main controller and writing the target upgrade package into the slave controller. This technical solution, by offsetting the starting address of the target upgrade package to the target address range of the main controller, solves the application upgrade matching risk between different main controllers and different slave controllers.
