DETAILED DESCRIPTION

In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the following will be described in detail with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the various embodiments of the present invention, many technical details are provided in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented.

The following embodiments are divided for the convenience of description and shall not constitute any limitation on the specific implementation of the present invention. The embodiments may be combined with each other and referenced to each other without contradiction.

The first embodiment of the present invention relates to a device upgrade method, which is applied to an electronic device, wherein the electronic device includes: two or more functional units, and the functional units include at least a communication unit. The specific process is shown in FIG1, and includes:

Step 101: Obtain an upgrade package of a functional unit to be upgraded through a communication unit.

In this embodiment, the communication unit at least includes an upgrade capability module (Upgrade Agent, UA), an upgrade control module (Upgrade Control, UC) and a boot module (BootLoader).

The function of the UA module is to use the upgrade package and symbol table to upgrade the differential block data and communicate with the ELB module; the BootLoader module of the communication unit is used to boot the UA upgrade function; the UC module is used to communicate with the network platform. The network platform can be an Internet of Things platform, which is only used as an example and is not limited to the network platform.

The function unit to be upgraded at least includes an ELB module, wherein the ELB module of the function unit to be upgraded has a function of booting a startup program and a function of establishing a communication connection with the communication unit.

The above communication connection method can be a wired connection or a wireless connection, wherein the wireless connection can be WiFi, Bluetooth, infrared, etc., which will not be described one by one here.

The process of obtaining the upgrade package in step 101 is that the UC module in the communication unit interacts with the network platform, transmits the request instruction, and receives the upgrade package. The specific process is shown in Figure 2, including:

Step 201: Send a registration information query request for the functional unit to be upgraded.

Step 202, receiving the returned registration information.

Step 203: Send an upgrade version query request for the functional unit to be upgraded.

Step 204, receiving information of the upgraded version.

Step 205: Send a request for obtaining the upgrade package of the functional unit to be upgraded.

Step 206: Receive the upgrade package.

The upgrade package is downloaded from the network platform through the above steps 201-206.

In this embodiment, the acquisition process may be interrupted. The reasons for the interruption may be poor network signal, network signal interruption, power outage, etc. This is just an example. In the actual process, there are many other reasons for the interruption, which will not be described one by one here.

In order to prevent repeated transmission after the interruption cause is eliminated, the breakpoint marking method is adopted.

Specifically, when an acquisition interruption occurs, the acquisition process is marked to generate a mark point, and the acquisition operation is continued from the mark point after recovery. There are two ways to mark the acquisition process to generate a mark point:

One is to track the entire acquisition process, mark the current acquisition reception progress and generate a marking point regardless of whether there is an interruption.

The other is that when an interruption occurs, an instruction indicating that an error has occurred is popped up, and the current acquisition and receiving progress is marked according to the instruction to generate a marking point.

Of course, the above two methods are only specific examples. In actual use, the acquisition process can also be marked to generate marking points in other ways, which will not be described here one by one.

It should be noted that the process of obtaining the breakpoint mark can be the process of receiving registration information, the process of receiving upgrade version information, the process of receiving upgrade package, and the process of obtaining the function data to be upgraded mentioned in the following steps, etc., which will not be described one by one here.

Step 102: store the upgrade package in the memory space of the communication unit.

Step 103: upgrading the functional unit to be upgraded through the communication unit according to the upgrade package.

In this implementation, the upgrade method of step 103 is specifically as follows:

After the upgrade package is downloaded, the UC module reports the download result to the network platform.

The UC module sends an upgrade request to the functional unit to be upgraded.

The UC module receives the returned upgrade instruction.

The UC module forwards the upgrade command to the Bootloader module.

The communication unit guides the execution of the UA module upgrade function through the boot function of the Bootloader module.

At the same time, the functional unit to be upgraded enters the upgrade program through the boot function of the ELB module, wherein the upgrade program includes receiving flashing, restarting and upgrading, etc.

Specifically, the specific process of executing the upgrade function of the UA module is shown in Figure 3:

Step 301: Acquire data of the functional unit to be upgraded.

Step 302: Store the acquired upgraded functional unit into the memory space of the communication unit.

Step 303, obtain a symbol table.

Specifically, a symbol table is generated according to the registration information of the existing function unit to be upgraded and the upgraded version information obtained from the network platform, wherein the symbol table is a comparison table of the registration information and the version information.

Step 304, obtaining differential block data according to the symbol table.

Specifically, the UA module splits the data in the function unit to be upgraded in combination with the comparison information in the symbol table to extract differential block data, wherein the differential block data is the upgradeable part of the data of the function unit to be upgraded, and the number of differential blocks can be one or more.

Step 305: Upgrade the differential block data according to the upgrade package.

It should be noted that the upgrade data stored in the upgrade package is differential data of the upgraded version, that is, data for upgrading the differential blocks of the functional unit data to be upgraded.

After the differential block data is upgraded, a flash request is sent to the functional unit.

The UA module receives the flashing instruction returned by the functional unit and flashes the functional unit.

After the flash is completed, the next differential block data is upgraded until all differential blocks are upgraded.

The communication unit UA module sends an upgrade completion notification to the ELB module of the upgraded functional unit.

After receiving the upgrade completion notification, the ELB module of the upgraded functional unit executes the boot function of the ELB module, restarts, and completes the upgrade of the functional unit.

The ELB module of the upgraded functional unit sends the functional unit upgrade result to the UC module.

The UC module forwards the upgrade results to the network platform.

The second embodiment of the present invention relates to a device upgrade method. The second embodiment is substantially the same as the first embodiment.

The difference is that in the first embodiment, the communication unit and the function unit to be upgraded are two units, that is, the other function units are upgraded through the communication unit, while in the second embodiment, the communication unit itself is upgraded.

In this implementation, since the upgraded functional unit is a communication unit, there is no need to send an upgrade instruction request in the specific implementation of step 103. After receiving and storing the upgrade package, the UA module upgrade function is directly guided and executed through the boot function of the Bootloader module, where the upgrade process of the UA module is steps 301-304 of Figure 3.

It should be noted that the acquisition object in step 301 and step 303 is the communication unit, which is different from the ELB module of the functional unit other than the communication unit in the first embodiment.

The step division of the above methods is only for the purpose of clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the scope of protection of this patent; adding insignificant modifications to the algorithm or process or introducing insignificant designs without changing the core design of the algorithm and process are all within the scope of protection of this patent.
