Detailed ways

The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application and cannot be understood as limiting the embodiments of the present application.

As shown in Figure 1, this application provides a method for updating firmware of an electronic device, in which the electronic device includes a first chip and a second chip. The above method specifically includes the following steps:

01: Get the firmware update file;

03: Update the electronic device system firmware written into the first chip according to the firmware update file;

05: Update the electronic device function firmware written into the second chip according to the updated electronic device system firmware.

The present application also provides an electronic device firmware update device. The electronic device firmware update method of the present application can be implemented by the electronic device firmware update device. Specifically, the electronic device firmware update device includes a file acquisition module, a system firmware update module and a functional firmware update module. The file acquisition module is used to acquire the firmware update file, and the system firmware update module is used to update the first file according to the firmware update file. The electronic device system firmware of the chip and the function firmware update module are used to update the electronic device function firmware written in the second chip according to the updated electronic device system firmware.

This application also provides a cleaning equipment, such as a cleaning robot, a cleaning system including a cleaning robot and a supporting base station, etc. The cleaning equipment can execute the electronic device firmware update method of this application. Specifically, the cleaning device includes a memory and a processor, where the memory stores a computer program, and the processor is used to obtain a firmware update file, and to update the electronic device system firmware written in the first chip according to the firmware update file, and use Update the electronic device function firmware written into the second chip according to the updated electronic device system firmware.

Specifically, the electronic device involved in this application generally includes multiple chips, including a first chip and a second chip. The first chip is generally provided to serve as the system core control chip of the electronic device, and the firmware written into the first chip is the system firmware of the electronic device. Firmware, also known as hardware driver, is used to enable the hardware to run normally in the software environment. System firmware generally refers to the operating system of a specific electronic device, such as the operating system of a music player, the operating system of a cleaning device, the operating system of an electronic dictionary, etc., all of which are system firmware.

The above-mentioned electronic device also includes one or more second chips used to serve as control chips for each functional hardware in the electronic device. The firmware written in the second chip is the functional firmware corresponding to each functional hardware in the electronic device. Functional firmware generally refers to the driver used in electronic equipment to enable the control chip corresponding to each functional hardware to operate normally in the software environment of the system firmware. For example, the firmware corresponding to the chip used to control the motor in a cleaning robot is functional firmware.

In order to ensure that the hardware of the electronic device runs without failure, at the software level of the electronic device, there must be no conflicts or failures in the software interaction between the system firmware and each functional firmware. In related technologies, after the system firmware is upgraded, since each functional firmware needs to be independently written and updated on each functional hardware control chip, if the functional firmware has not been updated, if the versions of the system firmware and the functional firmware cannot be the same, If it is not compatible, the electronic device will not function properly.

Therefore, in the solution provided by this application, in order to solve the above problem, a communication link is added between the first chip and the second chip, so that the system of the electronic device can use the system firmware as the basis for each function after updating the system firmware. The firmware is updated. In some examples, the electronic device first downloads and obtains the firmware update file through a communication link connected to the external network environment. Generally, the downloaded firmware update file is stored in a temporary storage area in the first chip.

In order to ensure that there is no conflict between files in the update, the firmware update file generally includes all files of the target version of the system firmware. When writing the first chip update system firmware, a complete overwriting method is used. This ensures that the written system firmware is complete and that its internal files will not cause unexpected incompatibility issues due to partial overwriting.

After the firmware update file is completely written into the first chip and the system firmware is updated, the communication link between the first chip and the second chip is used to update the system firmware to each function according to the files related to each functional firmware in the new version of the system firmware. The second chip issues and writes the update file of the new version of functional firmware. The update file may include all files of the new version of the functional firmware, or may only include files that are different from the current version of the functional firmware.

In this way, this application prioritizes upgrading the system firmware and then upgrades the functional firmware based on the system firmware. This eliminates the need to write independent writes to the control chips of the functional hardware, effectively simplifying the firmware update operation process. In addition, updating the functional firmware according to the system firmware can unify the versions of the system firmware and functional firmware, avoid control failures or functional failures that may be caused by inconsistent firmware versions, and improve the reliability of the operation of the cleaning equipment.

As shown in Figure 2, in some embodiments, after step 01, it also includes:

021: Verify the signature information of the firmware update file. If the signature information is wrong, go to step 022. If the signature information is correct, go to step 03;

022: Terminate the process of electronic device firmware update.

In some embodiments, the electronic device firmware updating apparatus further includes a signature verification module for verifying the signature information of the firmware update file, and for terminating the electronic device firmware updating process.

In some embodiments, the processor is further configured to verify the signature information of the firmware update file, and to terminate the process of updating the firmware of the electronic device.

Specifically, in order to ensure that the firmware update file obtained and saved during the firmware update process is consistent with the firmware update file released by the publisher, in some examples, before starting the update of the system firmware, the file saved to the temporary storage area is first verified. Whether the signature information of the firmware update file is consistent with the signature information of the firmware update file obtained by the electronic device through the external network environment. If they are consistent, it means that the saved firmware update file can be used to update the system firmware. If they are inconsistent, it means that it is saved. The firmware update file may have been tampered with and cannot be used for firmware updates. In this case, the system firmware update process should be terminated to avoid unpredictable problems after the firmware update. After the update process is terminated, if you want to continue the firmware update, you need to obtain additional firmware update files from other sources to ensure that their signature information is consistent with the signature information of the firmware update file released by the publisher.

In this way, this application can verify the correctness and authenticity of the firmware update file to a limited extent before updating the firmware, thereby avoiding errors in the update process and thus preventing the operation of the device from malfunctioning due to errors in the firmware update file.

As shown in Figure 3, in some embodiments, step 03 includes:

031: Set the electronic device to the first state. The first state is used to indicate that the firmware update file is currently being backed up;

032: In the first state, write the firmware update file into the backup storage area of the first chip;

033: Update the system firmware according to the firmware update file written to the backup storage area.

In some embodiments, the system firmware update module is used to put the electronic device into a first state, the first state is used to indicate that the firmware update file is currently being backed up, and is used to write the firmware update file in the first state. The backup storage area of the first chip is used to update the system firmware according to the firmware update file written in the backup storage area.

In some implementations, the processor is further configured to put the electronic device into a first state, where the first state is used to indicate that the firmware update file is currently being backed up, and to write the firmware update file to the first state in the first state. A backup storage area of a chip, and used to update the system firmware according to the firmware update file written in the backup storage area.

Specifically, the system firmware update process will be described in detail next. In some examples, the first chip is provided with an area specifically used to store upgrade status flag bits. The data stored in this area includes at least three types, one of which indicates that the firmware update file is currently being backed up, and the second indicates that the upgrade is currently being performed. The status of the system firmware, the third indicates the status of the current system firmware upgrade completion. Before starting the system firmware upgrade process, first set the upgrade status flag position to the first data, corresponding to the first status of the electronic device, that is, the status of the firmware update file currently being backed up, and then update the firmware stored in the temporary storage area. The file is written to the backup storage area of the first chip. The backup storage area is generally used to store backups of system firmware. The first chip is also provided with a firmware storage area for storing system firmware so that the system firmware can operate normally. Data writing between the backup storage area and the firmware storage area is compared. More convenient for temporary storage area. In addition, in order to ensure that the backed-up data will not be easily damaged and that the recovery of the device can be guaranteed, the backup storage area generally uses non-volatile memory, such as ROM, EPROM, EEPROM, etc. The solution provided by this application uses backup storage This feature ensures the storage stability of firmware update files.

After the firmware update file is written to the backup storage area, the system firmware is updated based on the firmware update file stored in the backup storage area. This method can effectively ensure the stability of the transmission of the firmware update file content during the update process and avoid A file copy error occurred.

In this way, the present application can first write the firmware update file into the backup storage area of the system chip after obtaining it, so as to facilitate writing the firmware update file to the system chip during the subsequent firmware update process and avoid file copying during the writing process. mistake.

In some embodiments, step 032 includes:

During the process of writing the firmware update file to the backup storage area, if the electronic device restarts, continue to write the firmware update file to the backup storage area based on the progress of writing the firmware update file to the backup storage area before the electronic device restarts; or

Re-write the firmware update file to the backup storage area.

In some embodiments, the system firmware update module is also used to continue writing the firmware update file to the backup storage area based on the writing progress of the firmware update file to the backup storage area before the electronic device is restarted, and to re-write the firmware update file to the backup storage area. Write to the backup store.

In some embodiments, the processor is also configured to continue writing the firmware update file to the backup storage area based on the writing progress of the firmware update file to the backup storage area before the electronic device is restarted, and to re-write the firmware update file to the backup storage area. Backup storage area.

Specifically, for electronic devices, the update process of system firmware or operating system is the most vulnerable period during use. Once the device experiences a power outage or other interference during the update process of system firmware or operating system, the device stops functioning. , then after restarting, because the underlying firmware or operating system of the system has been overwritten and written partially, and the written files cannot guarantee that the newly written files and the unoverwritten files can jointly support the operation of the firmware or operating system , at this time, the electronic equipment cannot start and operate normally, which is commonly known as "update power-off equipment becomes bricked".

In order to avoid this situation, this application gives priority to writing the firmware update file to the backup storage area of the first chip before the official update, rather than directly updating the system firmware from the temporary storage area. Such a buffer setting can avoid The initial power outage of the device affects the system firmware itself.

In some examples, during the process of writing the firmware update file to the backup storage area of the first chip, if the electronic device loses power or is restarted due to other interference, since the system firmware has not changed yet, Therefore, the system still starts normally based on the current version of the system firmware. The system can then detect the state of the electronic device before restarting by detecting the upgrade status flag bit. If the firmware update file is still being backed up, it means that the process of writing the firmware update file to the backup storage area was not done before the restart. over. In some examples, the system can also compare the consistency of the files saved in the current backup storage area with the obtained firmware update file. If they are inconsistent, it means that the process of writing the firmware update file to the backup storage area before restarting was not successful. Done.

In this case, the system can find the progress of writing the firmware update file to the backup storage area before restarting based on the difference between the file saved in the current backup storage area and the obtained firmware update file, and continue to proceed with the progress. Firmware update files are written to the backup storage area. In other examples, in order to ensure the stability of the backup file process, the system can also completely restart writing the firmware update file to the backup storage area. The specific method of re-applying the firmware update file is not limited to the above two, and can be adjusted according to the actual application scenario and situation.

In this way, the present application can restore the above-mentioned process when the electronic device unexpectedly restarts due to power outage or other reasons during the process of writing the firmware update file to the backup storage area, thereby avoiding the possibility of power outage or other unexpected reasons during the firmware update process. Electronic device firmware corruption issues.

As shown in Figure 4, in some embodiments, step 033 includes:

0331: Set the electronic device to the second state. The second state is used to indicate that the system firmware is currently being updated;

0332: In the second state, overwrite the firmware update file written in the backup storage area to the firmware storage area of the first chip to update the system firmware.

In some embodiments, the system firmware update module is used to put the electronic device into a second state, the second state is used to indicate that the system firmware is currently being updated, and is used to write to the backup storage area in the second state. The firmware update file overwrites and writes the firmware storage area of the first chip to update the system firmware.

In some embodiments, the processor is further configured to put the electronic device into a second state, the second state is used to indicate that the system firmware is currently being updated, and to write the firmware in the backup storage area in the second state. The update file overwrites and writes the firmware storage area of the first chip to update the system firmware.

Specifically, after the firmware update file is successfully written into the backup storage area, the preparatory work in the system firmware update process has been completed. Next, the data in the backup storage area needs to be overwritten and written into the firmware storage area to realize the transfer to the first chip. The purpose of writing a new version of system firmware.

In some examples, in order to indicate the current firmware upgrade status of the electronic device, the first chip upgrade status flag is set to the second data, corresponding to the second status of the electronic device, that is, the status in which the system firmware is currently being updated. Then, the system directly writes the firmware update file written in the backup storage area to the firmware storage area of the first chip in an overwriting manner to achieve the purpose of updating the system firmware. Among them, the method of overwriting can be to directly overwrite the firmware update file written in the backup storage area and write it into the firmware storage area. That is, the files originally stored in the firmware storage area will be directly overwritten and erased by the newly written files. Alternatively, the files in the backup storage area and the firmware storage area can be compared, and the files with differences can be overwritten and written into the firmware storage area to form a new version of the system firmware.

In this way, the present application can write the firmware update file written in the backup storage area into the firmware storage area of the system chip, and update the system firmware by restoring the backup.

In some embodiments, step 033 also includes:

When the backup firmware update file is overwritten into the firmware storage area, if the electronic device is restarted, verify the status of the electronic device;

When the electronic device is in the second state, the firmware update file written in the backup storage area is overwritten and written into the firmware storage area again.

In some embodiments, the system firmware update module is also used to verify the status of the electronic device if the electronic device restarts when the backup firmware update file is overwritten and written into the firmware storage area, and is used to verify the status of the electronic device when the electronic device is in the second state. If the status is in the status, re-write the firmware update file written to the backup storage area to the firmware storage area.

In some embodiments, the processor is also configured to verify the status of the electronic device if the electronic device restarts when the backup firmware update file is overwritten and written into the firmware storage area, and is configured to verify the status of the electronic device when the electronic device is in the second state. In the case of , re-write the firmware update file written to the backup storage area to the firmware storage area.

Specifically, for electronic devices, the update process of system firmware or operating system is the most vulnerable period during use. Once the device experiences a power outage or other interference during the update process of system firmware or operating system, causing the device to stop functioning, Then after restarting, because the underlying firmware or operating system of the system has been overwritten and partially written, and the written files cannot guarantee that the newly written files and the unoverwritten files can jointly support the operation of the firmware or operating system, At this time, the electronic equipment cannot start and operate normally, which is commonly known as "update power-off equipment becomes bricked".

In order to avoid this situation, during the update process of the system firmware provided by this application, the firmware update file is first written into the backup storage area of the first chip, that is, the area originally used to store system backup files to facilitate system recovery is used to store the firmware. The update file, in other words, during the process of writing the firmware update, the firmware update file is actually written directly into the firmware storage area as a backup file, and the system firmware is updated using the original backup method. With this update method, when the electronic device unexpectedly stops operating and restarts, causing the original firmware to be destroyed due to writing of new data, the system firmware is updated by restoring the backup, and the firmware saved in the backup storage area is updated. After the process of writing the file to the firmware storage area is completed and the device is restarted, the system firmware will be a complete new version of the system firmware and can run normally.

In some examples, if the electronic device unexpectedly loses power or stops operating unexpectedly during the process of writing the firmware update file in the backup storage area to the firmware storage area. After restarting, first confirm the upgrade status flag. If it indicates that the current device is still in the second state of upgrading the system firmware, then restart the process of writing the firmware update file in the backup storage area to the firmware storage area. At the end of the process, it will automatically Control electronics reboot to enable newly written system firmware. After restarting, the newly written system firmware takes effect and is enabled, and the operation of the electronic device returns to normal.

In this way, this application can recover files from the backup storage area to the firmware storage area, in the process of the electronic device writing the firmware update file from the backup storage area to the firmware storage area, and it restarts unexpectedly due to power outage or other reasons. Restoring the above process can avoid the problem of electronic device firmware damage caused by power outage or other unexpected reasons during the firmware update process.

As shown in Figure 5, in some embodiments, after step 03, it also includes:

04: Set the electronic device to the third state and control the electronic device to restart. The third state indicates that the system firmware upgrade is completed.

In some embodiments, the electronic device firmware updating device further includes a system firmware update termination module, which is used to set the electronic device to a third state and control the electronic device to restart. The third state indicates that the system firmware upgrade is completed.

In some embodiments, the processor is also used to set the electronic device to a third state and control the electronic device to restart. The third state indicates that the system firmware upgrade is completed.

Specifically, after the firmware update file is written into the firmware storage area, the electronic device needs to be restarted to implement the application of the new version of the system firmware. Based on the implementation described above, since the system will verify the data of the current upgrade status flag after restarting, in order to avoid falling into an endless cycle of rewriting the firmware update file, before restarting the electronic device to apply the new version of the system firmware , the first chip first sets the data of the upgrade status flag bit to the third data, corresponding to the third status of the electronic device, that is, corresponding to the status of the current system firmware upgrade of the electronic device, and then performs a restart. By doing so, the electronic device will start with a new version of the system firmware after a reboot.

In this way, this application can apply the newly written firmware by setting its own status and restarting, and end the system firmware update process.

As shown in step 6, in some embodiments, step 05 includes:

051: Obtain the target version configuration information of the functional firmware based on the updated system firmware;

052: According to the function firmware, obtain the current version configuration information of the function firmware;

053: When the target version configuration information and the current version configuration information do not match, write new data to the second chip according to the updated system firmware, and update the functional firmware.

In some embodiments, the functional firmware update module is used to obtain the target version configuration information of the functional firmware based on the updated system firmware, and is used to obtain the current version configuration information of the functional firmware based on the functional firmware, and is used to perform the target version on the target If the version configuration information does not match the current version configuration information, new data is written to the second chip according to the updated system firmware, and the functional firmware is updated.

In some implementations, the processor is further configured to obtain the target version configuration information of the functional firmware based on the updated system firmware, and to obtain the current version configuration information of the functional firmware based on the functional firmware, and to obtain the target version configuration information of the functional firmware based on the updated system firmware. If the configuration information does not match the current version configuration information, new data is written to the second chip according to the updated system firmware, and the functional firmware is updated.

Specifically, after the system firmware update is completed, the system obtains the version number of the current version of the system firmware that can match the supported functional firmware and the functional firmware configuration file corresponding to the version number from the updated system firmware, and obtains the above-mentioned The information is compared with the version number of the functional firmware and the functional firmware configuration file corresponding to each functional hardware of the current electronic device. If the two are inconsistent, the functional firmware needs to be updated according to the system firmware through the communication link between the first chip and the second chip. Make an update.

Generally, system firmware and functional firmware of the same version must be matched and supported. System firmware can also be compatible with functional firmware of multiple historical versions before the current version. That is, not every update of system firmware is accompanied by an update of functional firmware. However, when the system firmware version is newer and is no longer compatible with the older version of the functional firmware, the functional firmware needs to be updated together with the new version of the system firmware. In order to make the system firmware compatible with the functional firmware for a long enough time, when updating the functional firmware according to the system firmware, the updated version number of the functional firmware should be the same as the version number of the new version of the system firmware. In addition, in order to make the system firmware more compatible with the functional firmware, when updating the functional firmware based on the system firmware, the updated version of the functional firmware should be updated to the version that the new version of the system firmware is most stable compatible with and supported.

For example, in some examples, the currently updated system firmware version is v1.5.1.6, and its compatible function firmware version range is v1.5.1.3~v1.5.1.6, and the functions corresponding to a certain second chip are currently The functional firmware version of the hardware is v1.5.1.1, which means that the current functional firmware version is not within the compatible support range of the updated system firmware, and the functional firmware needs to be updated according to the system firmware. At this time, the system will obtain the version configuration information of the functional firmware from the second chip, and at the same time obtain the version configuration information of the new version of the functional firmware from the first chip based on the newly updated system firmware, and compare the obtained two sets of version configuration information. , the comparison result is no match. Therefore, at this time, the system sends the files required for the functional firmware update process from the first chip to the second chip and writes them into the second chip based on the file content of the new version of the functional firmware contained in the system firmware or the file content generated by booting the new version of the functional firmware. , to achieve functional firmware updates. The updated functional firmware version only needs to be updated within the range of v1.5.1.3~v1.5.1.6.

In this way, this application can update the functional firmware corresponding to the control chip of each functional hardware based on the functional firmware information included in the updated system firmware, so as to maintain the version matching between the system firmware and the functional firmware and improve the reliability of equipment operation. sex.

In some embodiments, step 052 includes:

Every preset interval, the current version configuration information of the function firmware is obtained.

In some implementations, the functional firmware update module is also used to obtain the current version configuration information of the functional firmware at preset intervals.

In some implementations, the processor is also configured to obtain the current version configuration information of the functional firmware at preset intervals.

Specifically, in addition to the time after the system firmware is updated, during the daily operation of the electronic device, unexpected errors may occur in the operation of the functional firmware in the system, resulting in a sudden mismatch or incompatibility between the functional firmware and the system firmware. Condition. In order to avoid the impact of this situation on the normal use of electronic equipment, the system will obtain the current version configuration information of the functional firmware every preset period of time in order to compare it with the version configuration information provided by the current system firmware to observe whether it matches. .
