As shown in fig. 1, the embedded system device 1 includes an automatic firmware update system 10, the automatic firmware update system 10 can be connected to the remote server 2 via a wireless communication link, the remote server 2 stores a firmware version corresponding to the embedded system device 1, and the automatic firmware update system 10 can perform an update operation of the firmware version of the embedded system device 1.
The automatic firmware update system 10 of the embedded system device 1 includes an application layer (application layer)11, a middleware layer (middleware)12 connected to the application layer 11, and a storage unit 15. The application layer 11 can wirelessly communicate with the remote server 2 to detect the firmware version of the corresponding embedded system device 1 stored in the remote server 2, and determine whether to update the firmware version of the embedded system device 1 according to whether the firmware version is updated.
Fig. 2 is a flowchart illustrating a firmware updating method of an embedded system device according to an embodiment of the present invention, including:
in step S01, the application layer first establishes wireless communication with the remote server.
Step S02, determining whether the firmware version of the corresponding embedded system device stored in the remote server is updated, if yes, performing step S03, otherwise, performing step S02.
Wherein the application layer 11 first establishes wireless communication with the remote server 2. When the wireless communication is established, the application layer 11 detects the firmware version of the corresponding embedded system device 1 stored in the remote server 2 to determine whether the firmware version of the corresponding embedded system device 1 stored in the remote server 2 is updated. For example, the application layer 11 can compare whether the version number of the firmware currently operated by the embedded system device 1 is the same as the version number of the firmware version corresponding to the embedded system device 1 stored in the remote server 2 to determine whether the firmware version corresponding to the embedded system device 1 stored in the remote server 2 is updated.
Step S03, the updated firmware version and the update policy are downloaded.
When the application layer 11 determines that the firmware version is new (yes), the application layer 11 downloads the firmware version and the update policy from the remote server 2, and performs step S04.
Step S04, storing the downloaded firmware version and the update policy.
Specifically, the downloaded firmware version and the downloaded update policy are stored in the storage unit 15.
In step S05, an update notification is issued.
Specifically, the application layer 11 issues an update notification to the intermediary layer 12 according to the update object of the firmware version.
Step S06, the update policy is read according to the update notification.
In particular, the interposer 12 reads the update policy from the storage unit 15 according to the update notification.
In step S07, it is determined whether the update policy is satisfied, if yes, step S08 is performed, otherwise, step S11 is performed.
The intermediate layer 12 determines whether the update policy is satisfied, and when the update policy is satisfied (yes), it indicates that the update job of the new firmware version is currently possible, and when the update policy is not satisfied (no), it indicates that the update job of the new firmware version is currently impossible.
In step S08, the firmware version is updated according to the read update policy.
Specifically, the intermediate layer 12 starts to update the new firmware version, and the developer of the embedded system device 1 can customize the update policy by himself and upload the new firmware version and the customized update policy to the remote server 2, the automatic firmware update system 10 can automatically download the new firmware version from the remote server 2 and automatically update the firmware version when the update policy is satisfied, and the user of the embedded system device 1 does not need to determine by himself whether the firmware version of the embedded system device 1 is updated or not, or manually download the new firmware version from the remote server 2, or think that it is a better time to perform the update operation of the new firmware version. Thus, the convenience of the embedded system device 1 is greatly improved, and the firmware version of the embedded system device 1 can be always maintained in the latest version, thereby improving the stability of the embedded system device 1.
In some embodiments, the remote server 2 stores a look-up table, as shown in table one below, in which a plurality of embedded system devices 1 supported by the remote server 2, a plurality of developers self-configured update policies, and a current firmware version are recorded. Therefore, when the embedded system device 1 establishes wireless communication with the remote server 2, the automatic firmware update system 10 can automatically confirm the comparison table stored in the remote server 2 to confirm whether the update is required based on the corresponding update policy in the comparison table and the current firmware version, and further automatically download the new firmware version from the remote server 2 and automatically perform the update operation of the firmware version when the update policy is satisfied.
| Firmware version | Device type # | Update policy |
| 0.1 | 5 | 1111.xml |
| 2.2 | 5 | 000.xml |
| 0.5 | 5 | 333.xml |
The device type # of the embedded system device 1 may be, for example, a 5 th generation product, etc., and the embodiment is only exemplified by the example that the comparison table includes three firmware versions due to space limitation, and the specific content in the comparison table is not limited in practical application.
Step S11, wait for a period of time.
Specifically, when the update policy is not satisfied (the determination result is "no"), the interposer 12 may wait for a period of time and determine whether the update policy is satisfied after the period of time elapses. The cycle time set in the present embodiment may be 30 seconds, that is, the interposer 12 may determine whether the update policy is satisfied every 30 seconds after receiving the update notification. Of course, in the present embodiment, the cycle is only illustrated as 30 seconds, and the user can set the specific value of the cycle according to actual needs.
The update policy may be that the automatic firmware update system 10 does not perform the update operation of the new firmware version when the embedded system device 1 is not in the low power state or the embedded system device 1 does not perform the data synchronization with the remote server 2, that is, when the embedded system device 1 is in the low power state or the embedded system device 1 performs the data synchronization with the remote server 2, and the automatic firmware update system 10 starts to perform the update operation of the new firmware version when the embedded system device 1 leaves the low power state or stops performing the data synchronization with the remote server 2. Therefore, the new firmware version can not be shut down when the update operation of the new firmware version is not completed due to insufficient power, so that the embedded system device 1 can not operate normally due to incomplete firmware update, or the data synchronization operation between the embedded system device 1 and the remote server 2 is interrupted due to the update operation of the new firmware version, so that the data loss is avoided.
Optionally, the firmware update system of the embedded system device further includes: a boot layer; and the core layer is used for receiving a rebooting instruction from the intermediate layer when the updating operation is completed and executing the rebooting instruction so as to start the booting guiding layer to perform a rebooting procedure.
