Fig. 1 is a flowchart of an upgrade method for upgrading a system at a device side according to an embodiment of the present disclosure, where the upgrade method may be performed by an upgrade apparatus, and the apparatus may be implemented by software and/or hardware, and the apparatus may be integrated in the device side or a server. As shown in fig. 1, the upgrade method includes:

And 11, when the equipment terminal works based on the current system image file, receiving a file to be upgraded, wherein the file to be upgraded comprises a start loader to be upgraded and the system image file to be upgraded.

In the embodiment of the disclosure, the device side includes a memory, where the memory includes a first memory partition, a second memory partition, and a third memory partition that are preset. The first storage partition is used for storing a starting guide file, and a starting jump address of the starting guide file is a starting address of the first storage partition; the second storage partition is used for storing the files to be upgraded when the current boot loader and the current system image file are stored in the third storage partition, and the third storage partition is used for storing the files to be upgraded when the current boot loader and the current system image file are stored in the second storage partition; the third storage partition is a temporary file (Temp) partition of the memory. The memory may be a physical memory such as a hard disk, flash memory (Flash), etc.

The device side is used for starting and guiding, supporting OTA upgrading, receiving an OTA upgrading packet and writing the OTA upgrading packet into a system mirror image of a memory (such as Flash); the current system image file is a system image file which is used for normal work (such as voice processing, interaction with a terminal and a client) at the equipment end at present; the file to be upgraded is the OTA upgrade package and comprises a boot loader to be upgraded and a system image file to be upgraded, wherein in the OTA upgrade package, the former part of data is the boot loader to be upgraded and the latter part of data is the system image file to be upgraded; the file to be upgraded (OTA upgrade package) is stored in a server corresponding to the equipment end, wherein the system image file to be upgraded is a system image file for upgrading a system of the equipment end.

In the embodiment of the present disclosure, the start address of the first storage partition, the start address of the second storage partition, and the start address of the third storage partition are all preset, specifically may be set according to actual needs, and the embodiment of the present disclosure does not specifically limit this.

In this embodiment of the present disclosure, the boot file is actually a boot loader (Bootloader), where the boot file is cured when shipped from the factory, and the start address of the second storage partition is set in the boot file, so that the boot file can automatically jump to the start address of the second storage partition after operation when the device restarts to operate the boot file each time.

The upgrading method provided by the embodiment of the disclosure can be executed by the equipment end. In step 11, when the device side works based on the current system image file and the device side needs to perform system upgrade, the device side receives a file to be upgraded including a boot loader to be upgraded and the system image file to be upgraded.

In the embodiment of the disclosure, the current boot loader is provided with the boot jump address of the current system image file, so that the device side can automatically jump to the boot jump address of the current system image file to run the current system image file after running the current boot loader, thereby enabling the device side to work normally based on the current system image file.

In the embodiment of the present disclosure, when the current boot loader and the current system image file are stored in the third storage partition, the current boot loader is stored in the second storage partition, and in the second storage partition, the boot jump address of the current boot loader is the start address of the second storage partition. Therefore, before the equipment end is upgraded, when the equipment end is restarted, the equipment end can jump to the starting address of the second storage partition after the boot file is started to run the current starting loader, so that the current system image file is jumped and transferred, and the equipment end can work based on the current system image file.

And step 12, writing the boot loader to be upgraded and the system image file to be upgraded into the storage partitions used for storing the file to be upgraded in the second storage partition and the third storage partition.

In the embodiment of the present disclosure, if the current boot loader and the current system image file are stored in the second storage partition, the third storage partition is a storage partition for storing the file to be upgraded, and at this time, in step 12, the boot loader to be upgraded and the system image file to be upgraded are written into the third storage partition. Specifically, the start loader to be upgraded is written from the start address of the third storage partition, and then the system image file to be upgraded is written.

If the current boot loader and the current system image file are stored in the third storage partition, the second storage partition is a storage partition for storing the file to be upgraded, and at this time, in step 12, the boot loader to be upgraded and the system image file to be upgraded are written into the second storage partition. Specifically, the start loader to be upgraded is written from the start address of the second storage partition, and then the system image file to be upgraded is written.

And step 13, when the equipment end is powered off and restarted, after the boot file is operated, jumping to the operation line to upgrade and start the loading program.

In the embodiment of the present disclosure, if the current boot loader and the current system image file are stored in the second storage partition, in step 12, after writing the file to be upgraded to the third storage partition, the boot loader to be upgraded needs to be copied to the start address of the second storage partition. Thus, in step 13, after running the boot file from the start address of the first storage partition, it is possible to jump to the start address of the second storage partition to run the boot loader to be upgraded.

In the embodiment of the present disclosure, if the current boot loader and the current system image file are stored in the third storage partition, after writing the file to be upgraded to the second storage partition in step 12, in step 13, after running the boot file from the start address of the first storage partition, the boot loader directly jumps to the start address of the second storage partition to run the boot loader to be upgraded.

And 14, after the loading program to be upgraded is started, the system image file to be upgraded is transferred in a skip mode, and system upgrading of the equipment end is completed.

In step 14, since the start jump address of the system image file to be upgraded (the start address of the system image file to be upgraded stored in the storage partition for storing the file to be upgraded) is set in the start loader to be upgraded, the device side automatically jumps to the start jump address of the system image file to be upgraded to run the system image file to be upgraded after running the start loader to be upgraded, thereby completing the system upgrade of the device side.

After the system upgrading of the equipment end is completed, the to-be-upgraded starting loading program is used as a current starting loading program, and the to-be-upgraded system image file is used as a current system image file to wait for next system updating.

In the embodiment of the present disclosure, the device side may be an embedded device side, and the embedded device side may be an embedded device side that completes a voice processing function and an interaction function with a terminal and a client in an environment with a low chip main frequency, a memory and a Flash (Flash), for example, the embedded device side is an intelligent voice vehicle-mounted bracket, and the implementation manner of the device side is not particularly limited in the embodiment of the present disclosure.

When the traditional intelligent voice vehicle-mounted support needs to be subjected to system upgrading, the intelligent voice vehicle-mounted support firstly needs to enter a special OTA mode, in the OTA mode, the intelligent voice vehicle-mounted support cannot carry out voice processing and uplink and downlink of audio data, only OTA upgrading packets can be received, and in the time of about 10 minutes, a user cannot normally use the voice function of the intelligent voice vehicle-mounted support, so that user experience is seriously affected. By the upgrade method provided by the embodiment of the disclosure, the intelligent voice vehicle-mounted support can still work normally when the system is upgraded, namely, the intelligent voice vehicle-mounted support can still receive an OTA upgrade packet in the system upgrade process, and can normally perform voice processing and uplink and downlink of audio data, so that the experience of an intelligent voice vehicle-mounted support user is improved.

According to the upgrading method for the system of the equipment end, when the equipment end works based on the current system image file, the file to be upgraded is received, the to-be-upgraded starting loading program and the to-be-upgraded system image file are written into the storage partition for storing the to-be-upgraded file, when the equipment end is powered off and restarted, the starting loading program is jumped from the starting guiding file to the to-be-upgraded starting loading program, and then the to-be-upgraded starting loading program is jumped to the to-be-upgraded system image file, so that under the condition that a user does not feel, the system upgrading, namely OTA upgrading, of the equipment end is completed, and the whole upgrading process does not influence the normal use of the equipment end by the user, so that the user experience is improved.

Fig. 2 is a flowchart of another method for upgrading a system at a device side according to an embodiment of the present disclosure, where the upgrading method may be performed by an upgrading apparatus, and the apparatus may be implemented by software and/or hardware, and the apparatus may be integrated in the device side or a server. As shown in fig. 2, the upgrade method includes:

and step 21, when the equipment terminal works based on the current system image file, receiving a file to be upgraded, wherein the file to be upgraded comprises a start loading program to be upgraded and the system image file to be upgraded.

In the embodiment of the present disclosure, the device side includes a memory, and fig. 3 is a schematic structural diagram of a memory in the embodiment of the present disclosure, and as shown in fig. 3, the memory includes a first memory partition 1, a second memory partition 2, and a third memory partition 3 that are preset. The first storage partition 1 is used for storing a starting guide file, and in the first storage partition 1, a starting jump address of the starting guide file is a starting address of the first storage partition 1; the second storage partition 2 currently stores a current boot loader (Bootloader) and a current system image file, and in the second storage partition 2, a boot jump address of the current boot loader is a start address of the second storage partition 2; the third storage partition 3 is a blank partition or the third storage partition 3 currently stores a historical boot loader (Bootloader) and a historical system image file.

In the embodiment of the present disclosure, as shown in fig. 3, the memory further includes a memory partition for storing Factory Data (Factory Data) and a memory partition for storing User Data (User Data).

In addition, for other descriptions of step 21 in the embodiments of the present disclosure, reference may be made to the description of step 11 in the foregoing embodiments, which is not repeated here.

It may be appreciated that, in the upgrade method according to the embodiment of the present disclosure, the second storage partition currently stores the current boot loader and the current system image file, the third storage partition is a blank partition or the third storage partition currently stores the historical boot loader and the historical system image file, and the third storage partition is executed on the premise that the third storage partition is used for storing the file to be upgraded.

And step 22, writing the boot loader to be upgraded and the system image file to be upgraded into the third storage partition.

In the embodiment of the present disclosure, since the second storage partition currently stores the current boot loader and the current system image file, the third storage partition serves as a storage partition for storing the file to be upgraded.

In the embodiment of the present disclosure, if the third storage partition is a blank partition, in step 22, the boot loader to be upgraded and the system image file to be upgraded are directly written into the third storage partition; if the third storage partition currently stores the historical boot loader and the historical system image file, in step 12, the boot loader to be upgraded and the system image file to be upgraded are written into the third storage partition, and the historical boot loader and the historical system image file in the third storage partition are covered.

The starting jump address of the to-be-upgraded starting loader is the starting address of the third memory partition 3. That is, in step 22, the boot loader to be upgraded is written from the start address of the third memory partition 3, and then the system image file to be upgraded is written.

In the embodiment of the present disclosure, a start jump address of a system image file to be upgraded is set in a start loader to be upgraded, so that after the start loader to be upgraded is operated, the start jump address of the system image file to be upgraded is automatically jumped to operate the system image file to be upgraded, so that an equipment end can normally operate based on the system image file to be upgraded.

In the embodiment of the present disclosure, after receiving the file to be upgraded, the device side further needs to verify the system image file to be upgraded before writing the boot loader to be upgraded and the system image file to be upgraded into the third storage partition, so as to verify whether the system image file to be upgraded is complete and true and reliable, and after the verification is passed, execute the step of writing the boot loader to be upgraded and the system image file to be upgraded into the third storage partition, that is, step 22. In the embodiment of the disclosure, the SHA256 algorithm may be used to verify the system image file to be upgraded.

In the embodiment of the present disclosure, in step 22, after the boot loader to be upgraded and the system image file to be upgraded are all written into the third storage partition, the device side further needs to verify the data stored in the third storage partition, that is, the boot loader to be upgraded and the system image file to be upgraded, specifically, may use the SHA256 algorithm to perform verification, and after the verification passes, the next operation is performed.

In some embodiments, after the data stored in the third storage partition, that is, the boot loader to be upgraded (Bootloader) and the image file of the system to be upgraded pass verification, the device side also needs to record the length of the boot loader to be upgraded and the corresponding verification value.

In the embodiment of the present disclosure, the lengths of the current boot loader and the boot loader to be upgraded are both fixed lengths set in advance. The length of the current boot loader may also be understood as the memory size occupied by the current boot loader in the second storage partition, and the length of the boot loader to be upgraded may also be understood as the memory size occupied by the current boot loader in the third storage partition.

It should be noted that, in the embodiment of the present disclosure, when the device side receives the file to be upgraded and writes the boot loader to be upgraded and the system image file to be upgraded into the third storage partition, the device side may still work currently based on the current system image file, and may not affect the user when using the device side.

And step 23, copying the boot loader to be upgraded to the second storage partition when the equipment end is powered off and restarted, and enabling the boot loader to be upgraded to cover the current boot loader.

In the embodiment of the present disclosure, as shown in fig. 4, in step 23, the device copies the boot loader to be upgraded to the second storage partition 2, and causes the boot loader to be upgraded to cover the current boot loader currently stored in the second storage partition 2, where the boot jump address of the boot loader to be upgraded is the start address of the second storage partition 2, and then the current boot loader to be upgraded and the current system image file are stored in the second storage partition 2.

In some embodiments, when the device side is powered off and restarted, the device side copies the boot loader to be upgraded to the second storage partition according to the pre-recorded length of the boot loader to be upgraded and the corresponding check value, where the length of the boot loader to be upgraded is used to determine the memory size of the second storage partition that needs to be occupied by the boot loader to be upgraded. And the check value corresponding to the to-be-upgraded starting loading program is used for checking the to-be-upgraded starting loading program.

And step 24, after the boot file is operated from the starting address of the first storage partition, jumping to the starting address of the second storage partition to operate the to-be-upgraded boot loader.

In the embodiment of the present disclosure, when the device side restarts, the device side first starts to run the boot file from the start address of the first storage partition after writing the boot loader to be upgraded into the second storage partition and covering the current boot loader. Because the starting address of the second storage partition is set in the starting guide file, the starting address of the second storage partition is automatically jumped to after the starting guide file is restarted and operated at the equipment end each time. Since the boot loader to be upgraded is already stored in the second storage partition over the current boot loader at this time, the boot loader to be upgraded will be run from the start address of the second storage partition at this time.

And step 25, after the to-be-upgraded starting loading program is operated, jumping to a starting jump address of the to-be-upgraded system image file to operate the to-be-upgraded system image file, and completing the system upgrading of the equipment end.

In step 25, since the start jump address of the system image file to be upgraded (the start address of the system image file to be upgraded stored in the third storage partition) is set in the start loader to be upgraded, the device side automatically jumps to the start jump address of the system image file to be upgraded to run the system image file to be upgraded after running the start loader to be upgraded, thereby completing the system upgrade of the device side.

The system upgrade from the current system image file to the system image file to be upgraded is completed, after that, as shown in fig. 4, at each restart of the device, the device jumps to the boot loader to be upgraded in the second storage partition 2 through the boot file in the first storage partition 1, and jumps to the system image file to be upgraded in the third storage partition 3 through the boot loader to be upgraded in the second storage partition 2, so that the device works based on the system image file to be upgraded after restarting.

In the embodiment of the disclosure, after the system upgrade of the device end is completed through the steps, the to-be-upgraded start loading program is used as the current start loading program, the to-be-upgraded system image file is used as the current system image file, and the next system upgrade is waited. In addition, other descriptions of the upgrade method provided by the embodiments of the present disclosure may refer to the descriptions of the foregoing embodiments, and are not repeated herein.

Fig. 5 is a flowchart of yet another method for upgrading a system at a device side according to an embodiment of the present disclosure, as shown in fig. 5, where the embodiment of the present disclosure only differs from the foregoing embodiment in that step 22 is followed by step 221.

Step 221, modifying a status flag bit corresponding to the first storage partition to a first status, where the first status is used to indicate that the step of copying the boot loader to be upgraded to the second storage partition is performed when the device is powered off and restarted.

In some embodiments, after writing the boot loader to be upgraded and the system image file to be upgraded into the third storage partition, and verifying the boot loader to be upgraded and the system image file to be upgraded in the third storage partition, the device side modifies a status flag bit corresponding to the first storage partition into the first status.

In the embodiment of the present disclosure, initially, a status flag bit corresponding to a first storage partition is in a second state, where the second state is used to indicate a start address of a second storage partition to jump to after a boot file is started when a device is powered off and restarted.

In the embodiment of the present disclosure, when the device side is powered off and restarted, the following step 222 is executed first, and then the step of copying the boot loader to be upgraded to the second storage partition and enabling the boot loader to be upgraded to cover the current boot loader is executed.

Step 222, detecting whether a status flag bit corresponding to the first storage partition is in a first status or a preset second status, where the second status is used to instruct the operation module to jump to the start address of the second storage partition after the operation of the boot file is started when the equipment end is powered off and restarted, if the status is detected as the first status, executing the step of copying the boot loader to be upgraded to the second storage partition, and enabling the boot loader to be upgraded to cover the current boot loader, and if the status is detected as the second status, jumping to the start address of the second storage partition after the operation of the boot file is started.

In the embodiment of the present disclosure, when the device side is powered off and restarted, the device side first detects a state value of a state flag bit corresponding to the first storage partition, and if the state value of the state flag bit corresponding to the first storage partition is the first state, it indicates that the boot loader to be upgraded and the system image file to be upgraded have been successfully written into the third storage partition, so that the step of copying the boot loader to be upgraded to the second storage partition and enabling the boot loader to be upgraded to cover the current boot loader is performed.

If the state value of the state flag bit corresponding to the first storage partition is the second state, the state flag bit corresponding to the first storage partition is not modified to the first state, so that after the boot file is started, the boot loader is jumped to the starting address of the second storage partition. At this time, the current boot loader is still stored in the second storage partition, and the boot jump address of the current boot loader is still the start address of the second storage partition, so that after the boot file is executed, the current boot loader is executed from the start address of the second storage partition, and then the current boot loader jumps to the boot jump address of the current system image file to execute the current system image file, so as to ensure that when the device terminal is powered off and restarted, if the state flag bit corresponding to the first storage partition is still detected to be in the second state, that is, when the device terminal fails to successfully upgrade to the system image file to be upgraded, the device terminal can still execute work based on the current system image file.

In addition, other descriptions of the upgrade method provided by the embodiments of the present disclosure may refer to the descriptions in the foregoing embodiments, and are not repeated here.

Fig. 6 is a flowchart of yet another method for upgrading a system at a device side according to an embodiment of the present disclosure, where the upgrading method may be performed by an upgrading apparatus, and the apparatus may be implemented by software and/or hardware, and the apparatus may be integrated in the device side or a server. As shown in fig. 6, the upgrade method includes:

and step 31, when the equipment terminal works based on the current system image file, receiving a file to be upgraded, wherein the file to be upgraded comprises a start loading program to be upgraded and the system image file to be upgraded.

In the embodiment of the present disclosure, the device side includes a memory, and fig. 7 is a schematic structural diagram of a memory in the embodiment of the present disclosure, and as shown in fig. 7, the memory includes a first memory partition 1, a second memory partition 2, and a third memory partition 3 that are set in advance. The first storage partition 1 is used for storing a starting guide file, and in the first storage partition 1, a starting jump address of the starting guide file is a starting address of the first storage partition 1; the second storage partition 2 currently stores a current boot loader (Bootloader) and a historical system image file, in the second storage partition 2, a boot jump address of the current boot loader is a starting address of the second storage partition 2, and the second storage partition 2 is used for storing a file to be upgraded; the third storage partition 3 currently stores the current boot loader and the current system image file.

In the disclosed embodiment, as shown in fig. 7, the device side memory further includes a specific memory partition 4.

In addition, for other descriptions of step 31 in the embodiments of the present disclosure, reference may be made to the descriptions of step 11 and step 21 in the foregoing embodiments, and the descriptions are not repeated here.

It may be appreciated that, in the upgrade method according to the embodiment of the present disclosure, the third storage partition currently stores the current boot loader and the current system image file, the second storage partition currently stores the current boot loader and the historical system image file, and the second storage partition is executed on the premise that the second storage partition stores the file to be upgraded.

Step 32, writing the boot loader to be upgraded into a specific memory partition.

And step 33, writing the boot loader to be upgraded and the system image file to be upgraded into the second storage partition.

In the embodiment of the present disclosure, since the third storage partition currently stores the current boot loader and the current system image file, the second storage partition serves as a storage partition for storing the file to be upgraded.

In step 33, the boot loader to be upgraded and the system image file to be upgraded are written to the second storage partition to overwrite the current boot loader and the historical system image file currently stored in the second storage partition.

In the embodiment of the disclosure, as shown in fig. 7, when the device side works based on the current system image file, the current boot loader and the historical system image file are currently stored in the second storage partition 2 of the memory. Fig. 8 is a schematic diagram of a structure of the memory after writing the boot loader to be upgraded and the system image file to be upgraded into the second storage partition, in step 33, as shown in fig. 8, after the device side writes the boot loader to be upgraded and the system image file to be upgraded into the second storage partition 2, the second storage partition 2 stores the boot loader to be upgraded and the system image file to be upgraded at this time. The starting jump address of the to-be-upgraded starting loader is the starting address of the second memory partition 2. That is, in step 33, the boot loader to be upgraded is written from the start address of the second memory partition 2, and then the system image file to be upgraded is written.

In the embodiment of the disclosure, the start jump address of the system image file to be upgraded is set in the start loading program to be upgraded, so that the start jump address of the system image file to be upgraded can be automatically jumped to run the system image file to be upgraded after the start loading program to be upgraded is run, and the equipment end can work normally based on the system image file to be upgraded.

In the embodiment of the present disclosure, after receiving the file to be upgraded, the device side further needs to verify the system image file to be upgraded before writing the boot loader to be upgraded and the system image file to be upgraded into the second storage partition, so as to verify whether the system image file to be upgraded is complete and true and reliable, and after the verification is passed, the step of writing the boot loader to be upgraded and the system image file to be upgraded into the second storage partition is performed, that is, step 33. In the embodiment of the disclosure, the SHA256 algorithm may be used to verify the system image file to be upgraded.

In the embodiment of the present disclosure, in step 33, after the boot loader to be upgraded and the system image file to be upgraded are all written into the second storage partition, the device side further needs to verify the data stored in the second storage partition, that is, the boot loader to be upgraded and the system image file to be upgraded, specifically, may use the SHA256 algorithm to perform verification, and after the verification is passed, the next operation is performed.

And step 34, when the equipment end is powered off and restarted, after the starting boot file is operated from the starting address of the first storage partition, jumping to the starting address of the second storage partition to operate the to-be-upgraded starting loader.

In the embodiment of the disclosure, when the device side is powered off and restarted, the boot file is started to run from the starting address of the first storage partition. Because the starting address of the second storage partition is set in the starting guide file, after the starting guide file is restarted and operated at the equipment end, the starting guide file is automatically jumped to the starting address of the second storage partition so as to operate the starting loader to be upgraded.

And step 35, after the to-be-upgraded start loading program is operated, jumping to a start jump address of the to-be-upgraded system image file to operate the to-be-upgraded system image file, and completing the system upgrading of the equipment end.

In step 35, since the start jump address of the system image file to be upgraded (the start address of the system image file to be upgraded stored in the second storage partition) is set in the start loader to be upgraded, the device side automatically jumps to the start jump address of the system image file to be upgraded to run the system image file to be upgraded after running the start loader to be upgraded, thereby completing the system upgrade of the device side.

The device end is started up to the system image file to be upgraded through the boot file, and then the device end is started up to the system image file to be upgraded through the boot loader to be upgraded.

In the embodiment of the disclosure, after the system upgrade of the device end is completed through the steps, the to-be-upgraded start loading program is used as the current start loading program, the to-be-upgraded system image file is used as the current system image file, and the next system upgrade is waited.

In some embodiments, referring to fig. 7 and fig. 8, if the boot loader to be upgraded and the system image file to be upgraded are not completely written into the second storage partition 2, when the device side is powered off and restarted, the device side cannot be started normally, i.e. the device side will have a brick change condition, because the boot loader to be upgraded and the system image file to be upgraded are not completely written into the boot loader to be upgraded, and the incompletely written boot loader to be upgraded already covers the current boot loader stored before the second storage partition 2.

In order to effectively avoid the problem that the boot loader to be upgraded and the system image file to be upgraded are not completely written into the second storage partition, the device side is powered off and restarted to cause the device side to have a brick changing condition, in some embodiments, if the boot loader to be upgraded and the system image file to be upgraded are not completely written into the second storage partition, the device side is powered off and restarted, the upgrading method further includes:

And 341, copying the current boot loader to the second storage partition, wherein the boot jump address of the current boot loader is the start address of the second storage partition, so that the device end can work based on the current system image file after restarting.

In step 341, referring to fig. 8, if the boot loader to be upgraded and the system image file to be upgraded are not completely written into the second storage partition 2, when the device side is powered off and restarted, the current boot loader is copied from the third storage partition 3 to the second storage partition 2 to cover the boot loader to be upgraded which is not completely written into the second storage partition 2, where after the copying is completed, the boot jump address of the current boot loader is the start address of the second storage partition 2, so that the device side can work based on the current system image file in the third storage partition 3 after restarting.

In some embodiments, since the length and the check value of the current boot loader are recorded in advance, in step 341, the current boot loader may be copied to the second storage partition according to the length of the current boot loader and the corresponding check value, where the length of the current boot loader is used to determine the memory size of the second storage partition that needs to be occupied by the current boot loader, and the corresponding check value of the current boot loader is used to check the current boot loader.

And 342, when the equipment terminal works based on the current system image file, copying the to-be-upgraded starting loader in the specific storage partition to the second storage partition, taking the starting jump address of the to-be-upgraded starting loader as the starting address of the second storage partition, and continuously writing the to-be-upgraded system image file into the second storage partition.

In step 342, when the device side works based on the current system image file, the device side copies the boot loader to be upgraded in the specific storage partition to the second storage partition to cover the current boot loader currently stored in the second storage partition, and continues to write the system image file to be upgraded to the second storage partition. The starting jump address of the to-be-upgraded starting loader is the starting address of the second storage partition.

After step 341 and step 342, when the device is powered off and restarted, the above step 34 is continuously performed to complete the system upgrade of the device.

In addition, other descriptions of the upgrade method provided by the embodiments of the present disclosure may refer to the descriptions of the foregoing embodiments, and are not repeated herein.

Fig. 9 is a flowchart of another method for upgrading a system at a device side according to an embodiment of the present disclosure, and as shown in fig. 9, unlike the upgrading method according to the foregoing embodiment, in the embodiment of the present disclosure, after the boot loader to be upgraded and the system image file to be upgraded are completely written to the second storage partition, that is, after step 33, step 331 is further included.

And 331, modifying a state flag bit corresponding to the first storage partition into a second state, wherein the second state is used for indicating that the device side is in power-off restarting and then jumps to the starting address of the second storage partition after the boot file is started.

In some embodiments, after writing the boot loader to be upgraded and the system image file to be upgraded into the second storage partition, and verifying the boot loader to be upgraded and the system image file to be upgraded in the second storage partition, the device side modifies the status flag bit corresponding to the first storage partition into the second status.

In order to effectively avoid the problem that the boot loader to be upgraded and the system image file to be upgraded are not completely written into the second storage partition, the device side is powered off and restarted to cause the device side to have a brick changing condition. Specifically, when the device side is powered off and restarted, before the boot file is started from the starting address of the first storage partition, the upgrading method further includes:

Step 332, detecting whether the status flag bit corresponding to the first storage partition is in the second status or the first status, if so, executing the step of jumping to the start address of the second storage partition to run the boot loader to be upgraded after running the boot file from the start address of the first storage partition, and if so, executing step 333.

In the embodiment of the present disclosure, when the device side is powered off and restarted, the device side first detects a state value of a state flag bit corresponding to the first storage partition, and if the state value of the state flag bit corresponding to the first storage partition is detected to be in the second state, the to-be-upgraded boot loader and the to-be-upgraded system image file are indicated to be successfully written into the second storage partition, so that after the boot file is run from a start address of the first storage partition, the device side jumps to a start address of the second storage partition to run the to-be-upgraded boot loader.

Because the boot loader to be upgraded and the system image file to be upgraded are not completely written into the second storage partition, the status flag bit corresponding to the first storage partition is not modified, i.e. the status flag bit corresponding to the first storage partition is still maintained in the first state at this time. If in step 332, it is detected that the status value of the status flag bit corresponding to the first storage partition is the first status, it indicates that the boot loader to be upgraded and the system image file to be upgraded are not written into or not completely written into the second storage partition, i.e. the device side fails to upgrade from the second system image file to the third system image file, so in order to ensure that the device side can still work normally, step 333 is executed to enable the device side to work based on the current system image file.

Step 333, copying the current boot loader to the second storage partition, where the boot jump address of the current boot loader is the start address of the second storage partition.

Because the status flag bit corresponding to the first storage partition is in the first status, which indicates that the boot loader to be upgraded and the system image file to be upgraded are not written into or not completely written into the second storage partition, the boot loader currently stored in the second storage partition is not completely written into the boot loader to be upgraded or other boot loaders, which may cause that the equipment end cannot be restarted and changes into a brick. In order to effectively prevent this, when it is detected that the status flag bit corresponding to the first storage partition is in the first status, in step 333, the current boot loader is first copied to the second storage partition to cover the incompletely written boot loader to be upgraded or other boot loader currently stored in the second storage partition, and the boot jump address of the current boot loader is made to be the start address of the second storage partition.

In some embodiments, since the length and the check value of the current boot loader are pre-recorded, in step 333, the current boot loader may be copied to the second storage partition according to the pre-recorded length of the current boot loader and the corresponding check value, where the length of the current boot loader is used to determine the memory size of the second storage partition that needs to be occupied by the current boot loader, and the corresponding check value of the current boot loader is used to check the current boot loader.

Step 334, after running the boot file from the start address of the first storage partition, jump to the start address of the second storage partition to run the current boot loader.

Step 335, after running the current boot loader, jumping to the boot jump address of the current system image file to run the current system image file, so that the device terminal works based on the current system image file.

In the embodiment of the present disclosure, if it is detected in step 332 that the status flag bit corresponding to the first storage partition is in the first status, the device side may be enabled to work based on the current system image file through steps 333 to 335. It should be noted that, step 341 in the foregoing embodiment includes steps 333 to 335 in the embodiment of the present disclosure.

In order to enable the device side to re-upgrade to the system image file to be upgraded after working based on the current system image file, i.e. after step 335, the method further includes:

and 336, when the equipment terminal works based on the current system image file, copying the boot loader to be upgraded in the specific storage partition to the second storage partition, continuously writing the system image file to be upgraded into the second storage partition, and jumping to step 331.

In step 336, when the device side works based on the current system image file, the device side copies the boot loader to be upgraded in the specific storage partition to the second storage partition to cover the current boot loader currently stored in the second storage partition, and continues to write the system image file to be upgraded to the second storage partition. The starting jump address of the to-be-upgraded starting loader is the starting address of the second storage partition. In step 336, after the boot loader to be upgraded and the system image file to be upgraded are completely written into the second storage partition, the process jumps to execute step 331.

In addition, the specific description of the upgrade method provided by the embodiments of the present disclosure may refer to the description of the foregoing embodiments, and will not be repeated here.

In the embodiment of the disclosure, the client judges whether the device side needs to perform system upgrade by judging whether the latest system image version number of the device side is consistent with the current system image version number of the device side. If the client judges that the latest system image version number of the equipment end is consistent with the current system image version number of the equipment end, the client judges that the equipment end does not need to be subjected to system upgrade, and if the client judges that the latest system image version number of the equipment end is inconsistent with the current system image version number of the equipment end, the client judges that the equipment end needs to be subjected to system upgrade.

Step 44, the client obtains the OTA upgrade package corresponding to the latest system image version information from the server.

In the embodiment of the disclosure, if the client determines that the device needs to perform system upgrade and checks that an OTA upgrade package corresponding to the latest system image version information exists at the server, the client downloads the OTA upgrade package from the server.

Step 45, the client transmits the OTA upgrade package to the device, where the OTA upgrade package includes a to-be-upgraded boot loader and a to-be-upgraded system image file.

In the embodiment of the disclosure, when the client transmits the above-mentioned OTA upgrade packet, a block transmission mode is adopted, that is, the client firstly divides the OTA upgrade packet into a plurality of pieces of OTA upgrade data, and then sequentially transmits the plurality of pieces of OTA upgrade data to the device.

In the embodiment of the disclosure, when abnormal conditions such as insufficient Bluetooth bandwidth, bluetooth disconnection, terminal outage, equipment end outage and the like are met, after Bluetooth bandwidth is abundant and Bluetooth connection is reestablished between the terminal and the equipment end, the client end carries out breakpoint continuous transmission on a plurality of pieces of OTA upgrade data until a complete OTA upgrade packet is transmitted to the equipment end.

When the bluetooth connection is re-established between the terminal and the device, if the client of the terminal detects that the OTA upgrade packet corresponding to the updated system image version number exists at the server again through the steps 41 to 44, the updated OTA upgrade packet is downloaded, and the updated OTA upgrade packet is transmitted to the device.

Step 46, when the device side works based on the current system image file, the device side receives a file to be upgraded, where the file to be upgraded is the OTA upgrade packet, and the file to be upgraded includes the boot loader to be upgraded and the system image file to be upgraded.

In step 46, when the device side works based on the current system image file, the device side receives the OTA upgrade packet transmitted by the client side, that is, the file to be upgraded, which includes the boot loader to be upgraded and the system image file to be upgraded.

In some embodiments, if the client transmits the OTA upgrade packet to the device in blocks, the device performs verification on each piece of OTA upgrade data first, specifically, may use SHA256 algorithm to perform verification, and after the verification is passed, performs the next operation.

For a specific description of step 48, reference is made to the description of step 221 in the foregoing embodiment, and no further description is given here.

Step 49, when the device side is powered off and restarted, the device side detects that the status flag bit corresponding to the first storage partition is in a first status or a second status, where the second status is used to indicate that the device side jumps to the start address of the second storage partition after running the boot file when the device side is powered off and restarted, if the status is detected as the first status, step 50 is executed, and if the status is detected as the second status, the device side jumps to the start address of the second storage partition after running the boot file when the device side is powered off and restarted.
