[0008] The software upgrade package is obtained from the backup area, and an upgrade operation is performed on the partition that is not currently running the code according to the software upgrade package.

[0009] Optionally, after storing the software upgrade package in the backup area and restarting the wearable device, the method further includes:

[0010] Obtain the flag information of the recorded system upgrade flag bit;

[0011] According to the flag information, it is determined whether the wearable device after restart needs to be upgraded.

[0012] Optionally, after performing the upgrade operation on the partition currently not running code according to the software upgrade package, the method further includes:

[0013] Verifying the software version of the upgraded partition that is not currently running the code according to the set verification items to obtain a first verification result;

[0014] When the first calibration result indicates that the upgraded software version of the partition that is not currently running the code has passed verification, the wearable device is restarted.

[0015] Optionally, the setting verification item includes: a verification item regarding whether the software version of the partition that is not currently running code after the upgrade is reliable.

[0016] Optionally, after storing the software upgrade package in the backup area and restarting the wearable device, the method further includes:

[0017] When the wearable device does not need to be upgraded after being restarted, verifying the software version of the first partition and the software version of the second partition according to the set verification item to obtain a second verification result;

[0018] When the second verification result indicates that the software version of the first partition passes verification and the software version of the second partition fails calibration, the first partition is used as the partition for currently running code;

[0019] When the second verification result indicates that the software version of the first partition fails verification and the software version of the second partition passes calibration, the second partition is used as the partition for currently running code.

[0020] Optionally, after the first calibration result indicates that the upgraded software version of the partition currently not running code has passed verification, the method further includes:

[0021] updating the operation area information;

[0022] The updating of the operating area information includes:

[0023] Update the partition identifier corresponding to the partition currently running the code

[0024] According to a second aspect of an embodiment of the present disclosure, a control apparatus for a wearable device is provided, wherein the partitions of the wearable device include a first partition, a second partition, and a backup area, and the apparatus includes:

[0025] A receiving module, used for receiving software upgrade packages;

[0026] A storage module, configured to store the software upgrade package in the backup area and restart the wearable device;

[0027] a determination module, configured to determine, when the wearable device needs to be upgraded after being restarted, a partition that is not currently running code from the first partition and the second partition according to the recorded running zone information;

[0028] An upgrade module is used to obtain the software upgrade package from the backup area and perform an upgrade operation on the partition that is not currently running code according to the software upgrade package.

[0029] Optionally, the determining module is specifically configured to:

[0030] Obtain the flag information of the recorded system upgrade flag bit;

[0036] One beneficial effect of the disclosed embodiment is that the partitions of the wearable device include a first partition, a second partition, and a backup area. After receiving a software upgrade package, the wearable device does not directly upgrade the partitions of the wearable device based on the software upgrade package. Instead, the software upgrade package is written to the backup area, and the wearable device is restarted before determining whether an upgrade is required. This can improve the reliability of the software upgrade. At the same time, if the wearable device needs to be upgraded after being restarted, the partition that is not currently running code will be determined from the first partition and the second partition based on the recorded running area information. The upgrade operation is performed only on the partition that is not currently running code based on the software upgrade package obtained from the backup area. In this way, if the upgrade of one partition fails, the code can be run normally based on another partition to ensure the normal operation of the wearable device.

[0049] <Hardware Configuration>

[0050] Figure 1 is a block diagram of a hardware configuration of a wearable device 1000 according to an embodiment of the present disclosure.

[0051] like Figure 1 As shown, the wearable device 1000 can be, for example, a smart watch, a smart bracelet, a head-mounted display, etc., which is not limited in the embodiments of the present disclosure.

The display device 1500 is, for example, a liquid crystal display, an LED display, a touch display, etc. The input device 1600 includes, for example, a touch screen, a keyboard, a handle, etc. The wearable device 1000 can output audio information through the speaker 1700 and collect audio information through the microphone 1800.

[0054] It should be understood by those skilled in the art that although Figure 1 , multiple devices of the wearable device 1000 are shown; however, the wearable device 1000 of the embodiment of this specification may only involve some of the devices, or may also include other devices, which is not limited here.

[0056] In the above description, a person skilled in the art can design instructions according to the solution provided by the present disclosure. How instructions control the operation of a processor is well known in the art and will not be described in detail here.

[0057] Figure 1 The wearable device shown is illustrative only and is in no way intended to limit the disclosure, its application, or uses.

[0058] <Method Example>

[0059] Figure 2 A software upgrade method for a wearable device according to an embodiment of the present disclosure is shown. The software upgrade method for the wearable device may be performed as follows. Figure 1The wearable device 1000 shown is implemented as follows. The wearable device 1000 can be a smart watch, a smart bracelet, a head-mounted display, etc. The partitions of the wearable device include a first partition, a second partition, and a backup partition. Generally, there is an active partition and an inactive partition in the first partition and the second partition, wherein the active partition is the partition currently running the code, and the inactive partition is the partition currently not running the code.

[0060] like Figure 2 As shown, the software upgrade method for a wearable device provided in this embodiment may include the following steps S2100 to S2400.

[0061] Step S2100: Receive a software upgrade package.

[0062] In this embodiment, when there is a software version upgrade, an external device such as a server can send a software upgrade package to the wearable device, and the wearable device can receive the software upgrade package sent by the server.

[0063] For example, the current software version is 3.0. If there is a software version upgrade in the server, such as software version 4.0, the software upgrade package corresponding to the software version 4.0 can be sent to the wearable device, and the wearable device can receive the software upgrade package corresponding to the software version 4.0.

[0064] After receiving the software upgrade package, enter:

[0065] Step S2200: store the software upgrade package in the backup area and restart the wearable device.

[0066] In related technologies, after receiving an upgrade package, a wearable device directly launches a bootloader and performs an upgrade based on the software upgrade package. In this embodiment, after receiving a software upgrade package, the wearable device first stores the software upgrade package in a backup area and restarts the wearable device before determining whether to perform an upgrade based on the software upgrade package on the partition of the wearable device that is not currently running code. This method of writing the software upgrade package to the backup area upon receipt improves the reliability of software upgrades and effectively avoids the problem of directly launching the bootloader and performing an upgrade based on the software upgrade package, which may result in an unsuccessful upgrade of the wearable device and subsequently render the wearable device unusable.

[0067] After storing the software upgrade package in the backup area and restarting the wearable device, enter:

[0068] Step S2300: When the wearable device needs to be upgraded after being restarted, a partition that is not currently running a code is determined from the first partition and the second partition according to the recorded running zone information.

[0069] In this embodiment, after restarting the wearable device, the wearable device will first obtain the flag information of the system upgrade flag recorded in the partition of the wearable device; and based on the flag information, determine whether the restarted wearable device needs to be upgraded. If it is determined that the restarted wearable device needs to be upgraded, it will determine the partition that is not currently running the code from the first partition and the second partition based on the recorded running area information.

[0070] Typically, after the software upgrade package is complete and successfully written to the backup area, the wearable device sets the system upgrade flag to 1 and records this flag in the wearable device's partition. Conversely, the system upgrade flag is set to 0 in the wearable device's partition and records this flag as 0. This means that if the flag is 1, the wearable device needs to be upgraded after reboot, and if it is 0, it does not need to be upgraded after reboot.

[0071] The above running zone information can indicate the partition identifier corresponding to the partition currently running the code. For example, when the flag information is 1, it indicates that the wearable device needs to be upgraded after restart. Here, the wearable device will obtain the running zone information recorded in the partition of the wearable device. For example, if the running zone information indicates that the partition identifier corresponding to the partition currently running the code is the first partition A, the first partition A will be used as the partition currently running the code, and the second partition B will be used as the partition not running the code.

[0072] When the wearable device needs to be upgraded after being restarted, after determining a partition that is not currently running code from the first partition and the second partition according to the recorded running zone information, enter:

[0073] Step S2400: Obtain the software upgrade package from the backup area, and perform an upgrade operation on the partition that is not currently running code according to the software upgrade package.

[0074] In this embodiment, after determining the partition currently not running code from the first and second partitions, the software upgrade package can be retrieved from the backup area. Then, based on the software upgrade package, the upgrade operation is performed only on the partition currently not running code. In this way, even if the upgrade of the partition currently not running code fails, since the partition currently running code has the latest software version, the partition currently running code can continue to be used, ensuring normal use of the wearable device. In other words, by using active and inactive areas, the problem of ensuring normal use of the wearable device can be effectively avoided in the event of a partition upgrade failure.

[0075] Continuing with the above example, the first partition A is the partition currently running the code, and the second partition B is the partition currently not running the code. Here, the wearable device can obtain the software upgrade package from the backup area and upgrade the second partition B according to the software upgrade package. This ensures that even if the upgrade of the second partition B fails, the wearable device can still use the first partition A.

[0076] According to an embodiment of the present disclosure, the partitions of the wearable device include a first partition, a second partition, and a backup area. After receiving a software upgrade package, the wearable device does not directly upgrade the partitions of the wearable device based on the software upgrade package. Instead, the software upgrade package is written to the backup area, and the wearable device is restarted before determining whether an upgrade is required. This can improve the reliability of the software upgrade. At the same time, if the wearable device needs to be upgraded after being restarted, the partition that is not currently running code will be determined from the first partition and the second partition based on the recorded running area information. The upgrade operation is performed only on the partition that is not currently running code based on the software upgrade package obtained from the backup area. In this way, if the upgrade of one partition fails, the code can be run normally based on another partition to ensure the normal operation of the wearable device.

[0077] In one embodiment, after executing the above step S2400 to obtain the software upgrade package from the backup area and performing an upgrade operation on the partition that is not currently running code according to the software upgrade package, the software upgrade method of the wearable device of the embodiment of the present disclosure may further include the following steps S3100 to S3200:

[0078] Step S3100: Verify the software version of the upgraded partition that is not currently running the code according to the set verification items to obtain a first verification result.

[0079] The set check item includes a check item regarding whether the software version of the partition currently not running any code after the upgrade is reliable.

[0080] In this embodiment, a set cyclic redundancy check code is stored in the partition of the wearable device. The set cyclic redundancy check code is the cyclic redundancy check code of the reliable software version. Here, the wearable device can obtain the cyclic redundancy check code of the upgraded partition that is not currently running the code, and compare the cyclic redundancy check code with the set cyclic redundancy check code.

[0081] Step S3200: When the first calibration result indicates that the software version of the partition that is not currently running the code has passed the verification after the upgrade, restart the wearable device.

[0082] In this embodiment, when the cyclic redundancy check code of the upgraded partition that is not currently running the code is the same as the set cyclic redundancy check code, it indicates that the software version of the upgraded partition that is not currently running the code has passed the verification, and the software version of the upgraded partition that is not currently running the code is determined to be a reliable software version. At this time, the wearable device can be restarted.

[0083] According to this embodiment, the wearable device will be restarted only when the software version of the partition that is not currently running the code is verified and passes the verification, and the software version of the partition that is not currently running the code is used as the reliable software version, thereby ensuring the reliability of the software upgrade.

[0084] In one embodiment, after executing the above step S2200 to store the software upgrade package in the backup area and restarting the wearable device, the software upgrade method of the wearable device of the embodiment of the present disclosure may further include the following steps S4100 to S4300:

[0085] Step S4100: When the wearable device does not need to be upgraded after being restarted, the software version of the first partition and the software version of the second partition are verified according to the set verification item to obtain a second verification result.

[0086] In this embodiment, after the wearable device writes the received software upgrade package into the backup area according to the above step S2200 and restarts the wearable device, the wearable device will first obtain the flag information of the system upgrade flag bit pre-recorded in the partition of the wearable device; and based on the flag information, determine whether the restarted wearable device needs to be upgraded, and if it is determined that the restarted wearable device does not need to be upgraded, the software version of the first partition and the software version of the second partition are verified according to the above-set verification items.

[0087] For example, when the flag information is 0, it indicates that the wearable device does not need to be upgraded after restart. At this time, since a set cyclic redundancy check code is preset in the partition of the wearable device, the set cyclic redundancy check code is a cyclic redundancy check code of a reliable software version. Here, the wearable device can obtain the cyclic redundancy check code of the first partition and the cyclic redundancy check code of the second partition, and compare these two cyclic redundancy check codes with the set cyclic redundancy check code respectively.

[0088] Step S4200: When the second verification result indicates that the software version of the first partition passes verification and the software version of the second partition fails calibration, the first partition is used as the partition for currently running code.

[0089] In this embodiment, when the cyclic redundancy check code of the first partition is the same as the set cyclic redundancy check code, and the cyclic redundancy check code of the second partition is different from the set cyclic redundancy check code, it indicates that the software version of the first partition has passed the verification, and also indicates that the software version of the first partition is a reliable software version.

[0090] Step S4300: When the second verification result indicates that the software version of the first partition fails verification and the software version of the second partition passes calibration, the second partition is used as the partition for currently running code.

[0091] In this embodiment, when the cyclic redundancy check code of the first partition is different from the set cyclic redundancy check code, and the cyclic redundancy check code of the second partition is the same as the set cyclic redundancy check code, it indicates that the software version of the second partition has passed the verification, and also indicates that the software version of the second partition is a reliable software version.

[0092] According to this embodiment, when the wearable device does not need to be upgraded, the software versions in the activation area and the inactivation area are also verified to ensure that the wearable device is running a reliable software version.

[0093] In one embodiment, after executing the above step S3200 and the first calibration result indicates that the software version of the partition that is not currently running the code after the upgrade has passed the verification, the software upgrade method of the wearable device of the embodiment of the present disclosure may further include: updating the running area information.

[0094] In this embodiment, updating the running area information may further include: updating the partition identifier corresponding to the partition of the currently running code.

[0095] For example, if the running area information indicates that the partition currently running the code is the first partition A, then when the software version in the partition currently not running the code, i.e., the second partition B, is a reliable software version, the wearable device will update the running area information to indicate that the partition currently running the code is the second partition B.

[0096] According to this embodiment, when the partition that is not currently running the code is upgraded and it is determined that the software version of the partition that is not currently running the code is a reliable software version, the partition that is not currently running the code will be switched to the partition that is currently running the code, thereby ensuring that the wearable device always runs the latest software version.

[0097] Next, an example of a software upgrade method for a wearable device is shown. In this example, the partition of the wearable device includes combining Figure 3 As shown, the software upgrade method of the wearable device includes the following steps:

[0098] Step S501: Receive a software upgrade package.

[0099] Step S502: store the software upgrade package in the backup area.

[0100] Step S503: restart the wearable device.

[0101] Step S504, obtaining the flag information of the recorded system upgrade flag, and determining whether an upgrade is required based on the flag information, if an upgrade is required, executing step S505, otherwise executing step S514.

[0102] Step S505, when it is determined that an upgrade is required based on the flag information, further determine from the first partition A and the second partition B based on the recorded running area information whether the partition currently running the code is the first partition A. If so, execute step S506, otherwise execute step S510.

[0103] Step S506: When the partition currently running the code is the first partition A, a software upgrade package is obtained from the backup area, and an upgrade operation is performed on the partition currently not running the code, ie, the second partition B, according to the software upgrade package.

[0104] Step S507 , determining whether the software version of the upgraded second partition B is a reliable software version. If so, executing step S508 ; otherwise, executing step S509 .

[0105] Step S508: If the software version of the upgraded second partition B is a reliable software version, set the software version of the upgraded partition that is not currently running code, namely the second partition B, as a reliable software version, and execute step S517.

[0106] Step S509: If the software version of the upgraded second partition B is not a reliable software version, set the software version of the partition currently running the code, ie, the first partition A, to a reliable software version, and execute step S517.

[0107] Step S510: When the partition currently running the code is the second partition B, a software upgrade package is obtained from the backup area, and an upgrade operation is performed on the partition currently not running the code, ie, the first partition A, according to the software upgrade package.

[0108] Step S511, determining whether the software version of the upgraded first partition A is a reliable software version, if yes, executing step S512, otherwise executing step S513.

[0109] Step S512: If the software version of the upgraded first partition A is a reliable software version, set the software version of the upgraded partition that is not currently running code, ie, the first partition A, as a reliable software version, and execute step S517.

[0110] Step S513: If the software version of the upgraded first partition A is not a reliable software version, set the software version of the partition currently running the code, ie, the second partition B, to a reliable software version, and execute step S517.

[0111] Step S514: When it is determined that no upgrade is required according to the flag information, further determine whether the reliable software version is the software version of the first partition A. If yes, execute step S515; otherwise, execute step S516.

[0112] Step S515: If the reliable software version is the software version of the first partition A, jump to the first partition A and the process ends.

[0113] Step S516: If the reliable software version is not the software version of the first partition A, jump to the second partition B and the process ends.

[0114] Step S517: Restart the head mounted display device.
