[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0045] Embodiments of the present application provide a program updating method, device, and electronic device. The electronic device or the program updating device may be disposed in a vehicle.

[0046] In addition, the term "plurality" in the embodiments of the present application refers to two or more than two. The terms "first" and "second" in the embodiments of the present application are used to distinguish descriptions and should not be understood as implying relative importance.

[0047] It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0048] See also Figure 1 , Figure 1 1 is a flowchart of a program update method provided by an embodiment of the present application. The program update method is applied to an electronic device, the electronic device includes a memory, the memory includes a first area and a second area; the first area includes a first program, the first program at least has the function of guiding the update of the second program; the second area includes the second program; the program update method may include:

[0049] S101, running the first program to guide the second program to be updated;

[0050] S102: If the second program fails to be updated, run the first program to enable the electronic device to achieve a target function.

[0051] It is understandable that in order to improve space utilization, data management efficiency, system stability, etc., the memory in the above electronic device can be divided into at least two areas to store different types of programs and / or data in different areas.

[0052] For example, if the memory is a Flash memory, the Flash memory can be divided into a Boot area and an App area. The Boot area is used to store a boot program, and the APP area is used to store an application program to enable the electronic device to implement various functions. The application program is a program required for the electronic device to implement a specific function, and at least one specific function constitutes the above-mentioned target function.

[0053] Alternatively, the Boot area can be further split into two levels, that is, the Boot area can be split into a BootRom area with the smallest working unit and a Bootloader area with a smaller working unit. The BootRom area and the Bootloader area work together during the boot process to ensure the correct loading and operation of the operating system. For example, if the program in the BootRom area is the first-level loading software, it can be used to boot the Bootloader area, such as booting the program in the Bootloader area to update, realize the jump from the APP area to the Bootloader area, and perform valid flag checks on programs in different areas (for example, check the flag indicating whether the program update in different areas is successful), etc., and the Bootloader area, as a secondary Boot, can be used to boot the App area, such as booting the program in the App area to update.

[0054] Alternatively, the App area may not be divided, and the application programs to be stored in the undivided App area may be stored in the Bootloader area, so that the original booting program in the Bootloader area can be used to boot the application programs in the Bootloader area, etc. The specific area division can be carried out according to needs, and different types of programs or data can be stored in the divided areas, which are not limited here.

[0055] In this regard, in the present embodiment, since the first program in the first area can be used to guide the second program in the second area to update, the first area can be a Boot area, the first program is a boot program in the Boot area, the second area can be an App area, and the second program is an application in the App area; or, the first area can be a BootRom area, the first program is a boot program in the BootRom area, the second area can be a Bootloader area, and the second program is a boot program in the Bootloader area; or, the first area can be a Bootloader area, the first program is a boot program in the Bootloader area, the second area can be an App area, and the second program is an application in the App area; or, the first area can be a partial area in the Bootloader area for storing the boot program, the first program is the boot program in the Bootloader area, the second area can be a partial area in the Bootloader area for storing the application program, the first program is an application in the Bootloader area, etc., which can be set specifically according to the needs and are not limited here.

[0056] Since, currently, when a program update fails, abnormal control of the electronic device may occur, that is, due to the failure of program update in a certain area in the memory, the program in the area cannot be used, or affects the use of programs in other areas, so that the electronic device cannot be controlled normally. Therefore, in this embodiment, the first program can be run to guide the second program to be updated, and then the update status of the second program is detected to clarify whether the second program fails to update. If the second program update fails, it means that the electronic device cannot be prompted to achieve the target function through the second program at present, and the first program can be used to remedy the situation, that is, by running the above-mentioned first program to enable the above-mentioned electronic device to achieve the target function, and the first program is used to maintain the electronic device to still achieve the target function, so as to avoid the abnormal control of the electronic device when the second program fails to update.

[0057] It should be noted that a controller may also be provided in the electronic device, and the controller is used to coordinate and control the various functions of the electronic device, and the memory plays an important role in the controller. For example, the above-mentioned memory may be a Flash memory, and the Flash memory may be used to support the storage of different programs for coordinating and controlling the various functions of the electronic device. If the program update in a certain area in the memory fails, the controller will become bricked.

[0058] Specifically, the method for guiding the update of the second program by the above-mentioned first program can be to erase the old version of the second program in the second area by the first program, and then write the new version of the second program in the second area by the first program; or, directly overwrite the old version of the second program with the new version of the second program by the first program, etc. The specific setting can be made according to needs and is not limited here.

[0059] In some embodiments, if the second program fails to be updated, before running the first program to enable the electronic device to achieve the target function, it is necessary to determine whether the second program has failed to be updated, and determine whether the second program has failed to be updated based on the update status during the update process of the second program, so that corresponding processing can be made in time according to the update status of the second program.

[0060] Specifically, the update duration of the second program can be obtained. If the update duration of the second program is greater than a preset duration threshold, it is determined that the update of the second program has failed; and / or the update result of the second program can be obtained. If the update result of the second program does not meet the preset update completion condition, it is determined that the update of the second program has failed, wherein the update completion condition may be the target content after the second program is updated. If the update result of the second program does not meet the target content, it is determined that the update result of the second program does not meet the preset update completion condition.

[0061] In some embodiments, since the target function of the above-mentioned electronic device needs to be implemented through a specific application, in this embodiment, the application that controls the electronic device to implement the target function can be set as a third program, that is, when the second area is the Bootloader area, at this time, the third program can be located in the Bootloader area or in the App area, and the second program in the Bootloader area is used to boot the third program to start, that is, the second program can jump to the third program to start the third program.

[0062] It is understandable that when the second program fails to update, the third program cannot be started. Therefore, in this embodiment, the first program is needed to restart the third program to ensure that the third program can run normally and control the electronic device to achieve the target function. Figure 2As shown, if the second program fails to be updated, the first program is run to enable the electronic device to achieve the target function, including:

[0063] S201, if the second program fails to be updated, jump to the third program by running the first program;

[0064] S202: Control the electronic device to achieve the target function based on the third program.

[0065] In this embodiment, by configuring a program in the first program to jump to the third program, when the second program fails to be updated, the first program can be used to re-implement the jump to the third program to start the third program to control the electronic device to achieve the target function, thereby avoiding the situation where the third program cannot be started due to the second program that starts the third program not being able to be used normally, resulting in abnormal control of the electronic device.

[0066] In some embodiments, in order to facilitate the clarification of the program status of the updated second area when the program is updated, that is, whether the program in the updated second area is updated successfully, the above-mentioned second area is configured with a first flag bit for indicating the program status, so that through the first flag bit, it is determined whether the corresponding second area has successfully updated the program. For example, when the second area is a Bootloader area, the first flag bit needs to be set for the Bootloader area. For example, when the second area is an App area, the first flag bit needs to be set for the App area.

[0067] Specifically, after the second program update fails, the method may further include: updating the first flag to indicate that the second program update fails, that is, the updated first flag is used to indicate that the program update in the second area fails.

[0068] In this embodiment, when the second program update fails, the first flag bit of the second area to which the second program belongs is updated, so that other threads can clearly know that there is an abnormality in the second area when running the program, and the second program in the second area cannot be used normally, or, it is convenient for relevant staff to locate the second area where the program update has an abnormality based on the first flag bit, so as to process the program with the update abnormality in the second area, thereby improving the speed at which relevant staff can find the program with the update abnormality.

[0069] In some embodiments, in order to enable relevant staff to quickly identify the program that currently has an update abnormality, it is necessary to prompt the relevant staff to remind them that there is a program that currently has an update abnormality, that is, after running the above-mentioned first program to jump to the third program, it can also include: through the above-mentioned third program, an error prompt is given based on the first flag bit after the update, and the above-mentioned error prompt is used to prompt that the update of the above-mentioned second program has failed.

[0070] In this embodiment, the validity of the second program in the second area can be checked through the third program, that is, after the first program starts the third program, the third program queries the first flag bit of the second area to which the second program belongs to determine whether there is a program with an update abnormality in the second area, that is, determine whether the second program has failed to update. When it is determined that there is a program with an update abnormality in the second area, that is, the update of the second program has failed, an error message can be given to prompt relevant staff members of the update failure of the second program, thereby enabling relevant staff members to discover the failure in time and take corresponding remedial measures, thereby improving the safety of electronic equipment.

[0071] In some embodiments, updating the first flag may include: updating the first flag by running the first program.

[0072] In this embodiment, since the second program needs to be updated through the first program, the first program can determine whether the second program fails to update in a relatively real time manner. Therefore, by updating the first flag bit of the second area through the first program, the first flag bit of the second area can indicate the current program status of the second area in real time and accurately.

[0073] In some embodiments, the second program also has the function of guiding the third program to update and controlling the electronic device to implement the first function. The method may also include: running the second program to guide the third program to update; if the third program fails to update, it stays in the second area and controls the electronic device to implement the first function based on the second program. The first function may be the same as the target function or different from the target function, which can be set according to the needs and is not limited here.

[0074] In this regard, in this embodiment, since the second program in the above-mentioned second area can be used to guide the third program to be updated, the second program can be run to guide the third program to be updated, and then the update status of the third program is detected to clarify whether the third program fails to update. If the third program fails to update, it means that the electronic device cannot be prompted to realize the first function through the third program at present, and the second program can be used to remedy the situation, that is, by running the above-mentioned second program to enable the above-mentioned electronic device to realize the first function, and by using the second program to maintain the electronic device to still realize the first function, abnormal control of the electronic device when the third program fails to update can be avoided.

[0075] In some embodiments, the method may further include: first, in response to a program update instruction for the electronic device, determining a target operating area, wherein the program update instruction includes a second flag, and the second flag is used to indicate the target operating area. Then, by running the first program or the second program in the target operating area, the second program or the third program is updated.

[0076] In this embodiment, the target operating area is determined by the second flag in the program update instruction. Since different target operating areas correspond to different security access levels, the second flag defines the security access levels of different areas when performing a program update to ensure security during program update.

[0077] Different second flag bits are used to indicate different areas. For example, one second flag bit is used to indicate a BootRom area, and another second flag bit is used to indicate a Bootloader area.

[0078] It is understandable that when the program is burned, a specific programming session instruction, that is, the above-mentioned program update instruction, will be entered to realize the jump of the program from the APP area to the Boot area. Since there are two levels of Boot, such as the BootRom area and the Bootloader area, it is necessary to distinguish the jump. That is, when performing security access, different levels of security access can be set, that is, different security access levels correspond to different second flag bits to indicate different levels of Boot areas. Therefore, different second flag bits can be written into the FLASH fixed area according to the security access level, so that when entering the programming session instruction to restart the jump, the BootRom area or the Bootloader area can be entered according to the difference in the second flag bit in the instruction.

[0079] In some embodiments, the first area is a BootRom area, the second area is a BootLoader area, the third program is an application program of the electronic device, and the third program is located in a third area, which can be an App area. Thus, in specific scenarios, it is possible to avoid abnormal control of the electronic device due to the failure of the third program to be used normally.

[0080] In some embodiments, since the target function of the above-mentioned electronic device needs to be implemented through a specific application, in this embodiment, the application that controls the electronic device to implement the target function can be set as a second program. At this time, the first program not only has the function of guiding the update of the second program, but also has the function of starting the second program.

[0081] It is understandable that when the second program fails to update, the second program cannot be used and cannot control the electronic device to achieve the target function. Therefore, in this embodiment, the first program is required to control the electronic device to achieve the target function, that is, the first program also has the function of controlling the electronic device to achieve the target function. Figure 3 As shown, the first program also has the function of controlling the electronic device to achieve the target function. If the second program fails to be updated, the first program is run to enable the electronic device to achieve the target function, including:

[0082] S301: If the second program fails to be updated, the device stays in the first area and controls the electronic device to achieve the target function based on the program function of the first program.

[0083] In this embodiment, a program that replaces the second program to control the electronic device to achieve the target function is configured in the first program, so that when the second program fails to be updated, the first program can replace the second program to re-control the electronic device to achieve the target function, thereby avoiding abnormal control of the electronic device due to the failure of the second program to be used normally.

[0084] In some embodiments, the first program includes at least part of the program functions of the second program, and the at least part of the program functions are used to control the electronic device to implement the target functions, so that the first program can be used to remedy some of the program functions when the second program fails to update, so as to avoid abnormal control of the electronic device due to the inability to use the second program normally. In addition, by maintaining only part of the program functions, the pressure on the storage space caused by the programs added to the first program to implement the program functions for the normal operation of the electronic device is also alleviated.

[0085] In some embodiments, at least part of the above-mentioned program functions may be basic function programs to achieve the target function of the electronic device, and the target function is the basic function corresponding to the basic function program. For example, the above-mentioned electronic device is arranged in a vehicle, and the above-mentioned target function includes at least one of a power management function, a safety management function, and a vehicle driving function.

[0086] Among them, the above-mentioned power management function can ensure that the vehicle can sleep / wake up normally and prevent the vehicle from entering an ultra-low power consumption state; the above-mentioned safety management function needs to support the triggering of a hard-wired signal to remind the upper-level controller that the program is lost, thereby ensuring that the entire vehicle can promptly and effectively remind the driver, such as airbags; the above-mentioned vehicle driving function needs to support the driving function to maintain the minimum control requirements, such as controlling the water pump / fan, etc., to ensure that the vehicle can maintain a lower speed operation, so that the driver can park the vehicle in a safe location.

[0087] In this embodiment, when the electronic device is a vehicle, the first program has at least the basic functional program in the second program, so that when the second program fails to update and cannot be used, it can ensure that the vehicle can be in a safe and reliable state, thereby reducing dependence on program backup and effectively reducing costs.

[0088] In order to better implement the program update method provided in the embodiment of the present application, the embodiment of the present application also provides a device based on the above program update method.
