Embodiment 1

[0044] Figure 2 Schematic diagram of a multi-firmware OTA upgrade method provided for embodiment I of the present invention, the present embodiment is applied to the server side, the server may be a variety of servers supporting OTA technology, thereby implementing a multi-firmware OTA upgrade. This embodiment does not limit this. The method may be performed by an upgrade apparatus provided in an embodiment of the present invention, the apparatus may be implemented in a software and / or hardware manner, and configured on the server side. Embodiments of the present invention specifically comprise the following steps:

[0045] Step 201, receive a plurality of firmware to be upgraded.

[0046] Exemplary, each firmware received is a signed encrypted packet and bound to the firmware's identification information storage. Wherein, the identification information of the firmware may include a firmware version number, and the firmware version number is raised successively.

Embodiment 2

[0053] Figure 3 Schematic diagram of the process of the multi-firmware OTA upgrade method provided for the present embodiment II. as Figure 3 As shown, embodiments of the present invention specifically comprise the following steps:

[0054] Step 201, receive a plurality of firmware to be upgraded.

[0055] Wherein, the firmware to be upgraded carries firmware and application information that has a dependency on this firmware upgrade. For example, when the latest version of firmware A has a dependency on the latest version of firmware B, the firmware data of firmware A and / or firmware B may carry information about the firmware dependent on it. Further, firmware A and / or firmware B may carry information dependent on the APP. Therefore, according to the information of the dependent firmware and APP carried by the firmware, the information of all the firmware that needs to be upgraded and the versions of the APP supported by these firmware can be determined. The firmware and appl...

Embodiment 3

[0063] Figure 4 Schematic diagram of the process of the multi-firmware OTA upgrade method provided for the present embodiment three. as Figure 4 As shown, embodiments of the present invention specifically comprise the following steps:

[0064] Step 201, receive a plurality of firmware to be upgraded.

[0065] Different from example TWO, the firmware received in step 201 of the present embodiment may not carry its dependency information with other firmware and APP.

[0066] Step 2021b, receiving a plurality of firmware information that needs to be merged into the firmware package to generate a firmware package, and generates a unique identification information of the firmware package, the firmware package is stored in binding to its unique identification information.

[0067] Among them, the information of multiple firmwares that need to be merged into the firmware package can be uploaded separately by the firmware developer. That is, after each firmware to be upgraded is uploaded ...

Abstract

The embodiment of the invention relates to the technical field of firmware upgrading, and discloses a multi-firmware OTA upgrading method and device, a server side and a storage medium. The upgrading method comprises the following steps: receiving a plurality of pieces of firmware to be upgraded; responding to a firmware upgrading request of the equipment side, and issuing a firmware package matched with the firmware upgrading request to the equipment side; wherein the firmware package is generated according to the dependency relationship among the multiple pieces of firmware to be upgraded and the dependency relationship between the multiple pieces of firmware and the application program. According to the embodiment of the invention, the management difficulty during multi-firmware upgrading with a complex dependency relationship is greatly reduced.

Description

Technical field [0001] Embodiments of the present invention relates to the field of Internet of Things technology, in particular to a multi-firmware OTA upgrade method and apparatus, server side and storage medium. Background [0002] In recent years, digital key technology applied to vehicles has developed rapidly. Digital key embedded systems often contain multiple modules, by multi-firmware to complete the digital key function, and multi-firmware version of the protocol interdependence, resulting in the system of a single firmware upgrade need to consider the specific version and support of each firmware (that is, dependencies), etc., and there is also a dependency between different firmware versions and digital key applications, so as the system continues to upgrade the firmware version of each version and its mutual support situation management difficulty is also increasing. Contents of the Invention [0003] Embodiments of the present invention provides a multi-firmware O...
