Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
The multi-firmware OTA upgrading method provided by the embodiment of the invention is suitable for upgrading the firmware of a system which comprises a plurality of firmware and has dependency relationship among the plurality of firmware and between the plurality of firmware and an application program. Such as the dependencies between multiple firmware, multiple firmware and applications shown in fig. 1. Namely, there is an inherent dependency relationship between different versions of different firmware, and there is a specific dependency relationship between different versions of different firmware and different APP versions. Illustratively, the multiple firmware items are firmware items A-C, respectively, with versions of the firmware items 1-N, for example. Application (APP) versions are, for example, between 2.0, 2.0-3.0, and 3.0 and above. The dashed lines with arrows in the figure indicate dependencies between different firmware and different firmware versions, and the solid lines with arrows indicate dependencies between different firmware and different firmware versions and different APP versions.
Taking digital key applications as an example, a digital key system often includes a plurality of modules, and a plurality of firmware is required to cooperate with each other to perform digital key functions, such as unlocking/locking with a digital key. The digital key system includes a plurality of firmware, such as bluetooth firmware, RSP (Remote Service Provider, RSP for short) firmware, and other related firmware. The digital key RSP realizes the mutual authentication of the intelligent equipment and the vehicle by using an asymmetric cryptographic algorithm. It will be appreciated that digital key applications often involve more than 2 pieces of firmware. The digital key APP can also be continuously updated along with the change of service requirements, so that a new digital key APP version is continuously generated.
The embodiment of the invention merges a plurality of firmware which have dependency relationship and support the same APP version into the firmware package, and issues the matched firmware package to the equipment terminal during upgrading, thereby greatly simplifying the management problem of multi-firmware upgrading with complex dependency relationship.
Example one
Fig. 2 is a flowchart illustrating a multi-firmware OTA upgrading method according to an embodiment of the present invention, where the embodiment is applied to a server, which may be various servers supporting OTA technology, so as to implement OTA upgrading of multiple firmware. The present embodiment does not limit this. The method can be executed by an upgrading device provided by the embodiment of the invention, and the device can be realized in a software and/or hardware manner and is configured at a server side. The embodiment of the invention specifically comprises the following steps:
Illustratively, each received firmware is a signature encryption data packet and is stored in a binding mode with identification information of the firmware. The identification information of the firmware may include a firmware version number, and the firmware version number is gradually increased.
Specifically, the firmware can be uploaded to the server after being manufactured by a firmware developer. When the firmware is uploaded, the type of the firmware to be uploaded can be selected first, that is, the firmware is bluetooth firmware or other types of firmware. And then, verifying the firmware to be uploaded, after the verification is successful, extracting basic information of the firmware, such as file header length, firmware version number, hardware code and the like, as identification information of the firmware, signing and encrypting the firmware to generate an encrypted firmware data packet to be upgraded, and uploading the encrypted firmware data packet to a server.
The firmware version number is raised every time the firmware is updated, thereby facilitating to ensure the uniqueness of the firmware version.
The firmware package is generated according to the dependency relationship among the plurality of firmware to be upgraded and the dependency relationship between the plurality of firmware and the application program. In other words, the firmware package includes all the firmware that needs to be upgraded in the upgrade process, that is, there is a dependency relationship between the firmware, for example, the firmware a needs to be upgraded to the latest version while the firmware B needs to be upgraded to the latest version, and the firmware can support the APP of the same version, for example, the lowest version of the APP supported by all the firmware is used as the APP version supported by the firmware. Wherein the generated firmware package has unique identification information. The service end may directly send the firmware package to an equipment end, such as a car end, or may send the firmware package to the car end through a smart phone, and the like, which is not limited herein.
Compared with the prior art, the multi-firmware OTA upgrading method provided by the embodiment of the invention generates the firmware package according to the dependency relationship among the plurality of firmware to be upgraded and the dependency relationship between the plurality of firmware and the application program, and issues the firmware package matched with the firmware upgrading request to the equipment end to realize the cooperative upgrading of the plurality of firmware, so that the management difficulty of the multi-firmware upgrading with complex dependency relationship is greatly simplified.
Example two
Fig. 3 is a flowchart illustrating a multi-firmware OTA upgrading method according to the second embodiment. As shown in fig. 3, the embodiment of the present invention specifically includes the following steps:
The firmware to be upgraded carries information of the firmware and the application program which have a dependency relationship with the firmware upgrade. For example, when the latest version of firmware a has a dependency relationship with the latest version of firmware B, the firmware data of firmware a and/or firmware B may carry information of the firmware it depends on. Also, firmware a and/or firmware B may carry information of dependent APPs. Therefore, the information of all firmware needing to be upgraded at this time and the versions of APPs supported by the firmware can be determined according to the information of the dependent firmware and APP carried by the firmware. The information of the firmware and the application program which are carried by the firmware to be upgraded and have the dependency relationship with the firmware upgrade can be added by a firmware developer, so that the dependency relationship between the firmware and the APP can be automatically managed by adding the dependency information in the firmware, and the management difficulty of the multi-firmware upgrade is greatly reduced.
And the interdependent multiple firmware is all the firmware which needs to be synchronously upgraded when the corresponding upgrade is completed. As described above, information of all firmware can be obtained through the dependency information carried by the firmware, and the carried dependency information is removed to obtain a plurality of mutually dependent clean firmware, and the plurality of clean firmware is used as one firmware package, for example, the plurality of firmware can be made into one compressed package.
It will be appreciated that the firmware package may have unique identification information, thereby ensuring the uniqueness of the firmware package. The unique identification information of the firmware package may include: application version information supported by the firmware package and device type information for a device upgraded with the firmware package. The upgrading of the firmware of different devices can be distinguished through the device types, and the firmware packages matched with the APP versions can be conveniently searched through the APP version information. Specifically, the version number of the firmware package may adopt a 3-segment code, such as 1.1.1, and the version number of the firmware package increases with the increase of the upgrade times, for example, when the current version number of the firmware package is 1.1.1, the version number of the firmware package can only be upgraded to 1.1.2, but cannot be reduced to 1.1.0.
The upgrading request carries version information of the application program and the equipment type of the equipment end of the firmware to be upgraded, so that the corresponding firmware package is matched according to the version information of the APP and the equipment type of the equipment end of the firmware to be upgraded, and the firmware package is issued to the equipment end. It will be appreciated that the firmware package may be twice encrypted to further enhance data security. Meanwhile, the firmware package may be sent to the device side in a fragmented manner, which is not limited herein.
Compared with the prior art, the multi-firmware OTA upgrading method provided by the embodiment of the invention generates the firmware package according to the dependency relationship among the plurality of firmware to be upgraded and the dependency relationship between the plurality of firmware and the application program, and issues the firmware package matched with the firmware upgrading request to the equipment end to realize the cooperative upgrading of the plurality of firmware, so that the management difficulty of the multi-firmware upgrading with complex dependency relationship is greatly simplified.
EXAMPLE III
Fig. 4 is a flowchart illustrating a multi-firmware OTA upgrading method provided in the third embodiment. As shown in fig. 4, the embodiment of the present invention specifically includes the following steps:
Unlike the second embodiment, the firmware received in step 201 in this embodiment may not carry the dependency relationship information between the firmware and other firmware and APP.
Wherein information that requires multiple pieces of firmware to be incorporated into a firmware package can be uploaded separately by a firmware developer. After each firmware to be upgraded is uploaded to the server, the information of the plurality of input firmware which needs to be put into the same firmware package can be collected through the terminal and sent to the server.
Specifically, the name and version of the firmware package may be defined and guaranteed to be unique. The upgraded firmware type and supported hardware type may be selected. Firmware types are for example bluetooth and RSP firmware, and hardware types are for example vehicles. All firmware versions supported by the system may be queried, the required base firmware versions selected, and the optional upgraded firmware versions selected according to different firmware types. For example, when a first version firmware package is manufactured, all firmware may be selected to put the firmware of the first version of all firmware into the firmware package, and when an upgrade is required, only the firmware that needs to be upgraded may be selected to be put into the firmware package. All the APP versions which are on the shelf can be inquired, the lowest APP version which is supported by all the firmware in the firmware package is selected, and then the dependency information among the firmware and the dependency information of the firmware and the APP are sent to the server side. It is understood that, in some examples, the firmware package may also be generated directly at the terminal and sent to the server. It should be noted that after the firmware package is generated, the uniqueness of the firmware package may be further verified, for example, by comparing the version of each sub-firmware in the firmware package, it is ensured that the version of each sub-firmware is successively increased each time of upgrading, and on the basis, when the versions of the sub-firmware in the firmware package are different, the uniqueness of the firmware package may be determined.
This step may be the same as step 2022a of the second embodiment, and is not described here again.
Compared with the prior art, the multi-firmware OTA upgrading method provided by the embodiment of the invention generates the firmware package according to the dependency relationship among the plurality of firmware to be upgraded and the dependency relationship between the plurality of firmware and the application program, and issues the firmware package matched with the firmware upgrading request to the equipment end to realize the cooperative upgrading of the plurality of firmware, so that the management difficulty of the multi-firmware upgrading with complex dependency relationship is greatly simplified.
Example four

The second embodiment is substantially the same as the second embodiment, and mainly differs in that the second embodiment generates and stores the firmware package in the server and issues the stored firmware package to the device when the device needs to be upgraded, and in the second embodiment, when an upgrade request of the device is received, the firmware package is generated in real time and issued to the device, and the server does not need to store the firmware package. As shown in fig. 5, the embodiment of the present invention specifically includes the following steps:
The firmware to be upgraded carries information of the firmware and the application program which have a dependency relationship with the firmware upgrade.
Specifically, the firmware matched with the APP version can be screened according to the version information of the application program carried in the upgrade request, the firmware type can be determined according to the device type of the device end of the firmware to be upgraded carried in the upgrade request, and all the firmware and firmware versions thereof required to be synchronously upgraded can be further determined according to the information of the firmware and the application program which are carried in the firmware and have a dependency relationship with the firmware upgrade, so that the firmware package corresponding to the upgrade request is generated in real time. The unique identification information of the firmware package may also be generated, and is not limited herein. The storage space of the server side can be saved by generating the firmware package in real time.
