[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of the present invention to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0031] The division of the following embodiments is for ease of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined with and referenced by each other without contradiction.

[0032] The first embodiment of the present invention relates to a method for launching an application. The specific process is as follows: Figure 1 As shown.

[0033] In step 101, the client obtains the demand information of the user and the hardware information of the Internet of Things device.

[0034] In the embodiment, the Internet of Things device mainly refers to a chip in the Internet of Things device. A blank chip without setting is connected to the server of the application through a serial port, and the chip is configured by the server, BootLoader is imported, and the device is started for application.

[0035] Specifically, the user inputs the model and storage space of the chip device on the client page, wherein the storage space includes flash memory and random access memory (RAM).

[0036] In one specific example, the user inputs the chip model to be configured as STM32F413ZHT6, the Flash is 1.5 MB, and the RAM is 320 KB.

[0037] The demand information includes partition information of the storage space of the chip device, including the start address and partition size of each partition. Generally, it is divided into three areas: boot program storage area, data storage area and application storage area. Among them, the boot program storage area is used to store BootLoader, the data storage area is mainly used to store application upgrade package, and the application storage area is used to store the application program of the Internet of Things device.

[0038] In step 102, the code file of the corresponding boot program is obtained according to the hardware information.

[0039] In the embodiment, the script can call different BootLoader code files according to different devices, including general code files and special model code files. If the input chip model does not have a corresponding code file, the general code file is used, wherein the script of the embodiment is a shell script running on Linux.

[0040] Specifically, the model information in the hardware information contains MCU kernel and model related macros. The kernel and macros corresponding to the model are determined according to the model script, such as selecting STM32L452xx to define the compilation parameters kernel=cortex-m4 and STM32L452xx macro in makefile.

[0041] It is worth mentioning that an ID number can be added in the code file. The ID is a unique number of BootLoader, which can be checked according to the authentication code. If the check is correct, other operations such as upgrading can be performed.

[0042] In step 103, the Internet of Things device is configured according to the demand information and hardware information.

[0043] In the embodiment, according to step 101, it can be known that the requirement information includes partition information, and the Flash and the RAM are configured according to the partition information. The configuration methods in the Flash and the RAM are similar, and here only the Flash configuration is specifically described.

[0044] Specifically, the start address and the size of the boot startup program storage area determine the maximum value and the start address of the bin file of the BootLoader, if the BootLoader is not at the start address of the Flash, the interrupt vector table is modified; the start address and the size of the application storage area determine the jump position of the BootLoader and the maximum value of the bin file of the application program; the start address and the size of the data storage area determine the start address and the maximum value of the upgrade package, wherein the maximum value of the upgrade package is the size of the data storage area minus two Block sizes. The two Block are respectively the last two Block of the data storage area, wherein the last Block is the parameter area, and the second last Block is the restore backup area. The positions of the areas must not overlap.

[0045] It should be noted that the classification of the division of the areas is only an example, and different division can be made according to actual needs.

[0046] After the start address and the size of each area are configured, the script automatically modifies the ID file and the header file.

[0047] In the embodiment, the hardware information further includes serial port information. Since the diversity of actual application of users and the difference of different platforms determine that the serial port cannot have a unified driver, it is necessary for the user to upload a customized serial port driver file (usart.c and usart.h), and the script will read the initialization function from the usart.h according to the configured serial port name.

[0048] Step 104, the code file is compiled and sent to the configured Internet of Things device, for the Internet of Things device to start the application.

[0049] In the embodiment, the compiler of the BootLoader is gcc-arm-none-eabi, and in the compiling process, arm-none-eabi-gcc and arm-none-eabi-objcopy are mainly used, and BID.bin is generated after successful compilation, and “build error!” is reported in case of compilation failure (including flash configuration error, RAM configuration error and code error).

[0050] The compiling process is as shown in Figure 2 , which includes:

[0051] Step 201, the corresponding code file of the script call ".c file" is preprocessed to generate a preprocessing file ".i file";

[0052] Step 202, the preprocessed file is compiled to generate an assembly file ".s file";

[0053] Step 203, the assembly file is assembled to generate an object file ".o file";

[0054] Step 204, the object file is combined with other object files, library files and startup files to generate an executable file;

[0055] Step 205, the generated executable file is sent to the Internet of Things device.

[0056] Specifically, the following tools are needed: arm-none-eabi-gcc is a c language compiler that can convert.c files into.o executable files; arm-none-eabi-g++ is a c++ language compiler that can convert.cpp files into.o executable files; arm-none-eabi-ld is a linker that links all.o files to generate an executable file. Generally, we do not use arm-none-eabi-ld instructions to call it, but use arm-none-eabi-gcc to call it because the former has poor support for mixed.o files generated by c / cpp files, so the official manual also recommends using arm-none-eabi-gcc instructions instead of arm-none-eabi-ld; arm-none-eabi-objcopy converts the linker-generated file into a bin / hex format for burning into the Internet of Things device; arm-none-eabi-gdb is a debugger in the tool chain that connects to the network port generated by the debugger hardware to debug the hardware and code.

[0057] It should be noted that the present embodiment uses gcc for compilation, but the compilation method is not limited thereto, and in addition to gcc, keil or iar can also be used for compilation, but gcc is more suitable for running on linux.

[0058] The step division of the above methods is only for clarity, and in implementation, one step can be combined or some steps can be split and decomposed into multiple steps, as long as the same logical relationship is included, and all are within the protection scope of the present patent; adding insignificant modifications or introducing insignificant designs in the algorithm or process, but not changing the core design of the algorithm and process are within the protection scope of the present patent.

[0059] The second embodiment of the present invention relates to a method for launching an application, applied after the code file has been sent to an IoT device. Specific steps are as follows: Figure 3 As shown:

[0060] Step 301: Detect whether an application upgrade package exists in the data storage area of ​​the IoT device through the bootloader;

[0061] In this embodiment, the application upgrade package only contains the differences between the new and old versions of the application;

[0062] After detecting the existence of the application upgrade package, proceed to step 302.

[0063] Step 302: Ask the user if they want to upgrade;

[0064] It should be noted that, yes, you can set up step 303 to proceed with the upgrade only after the user interacts and their needs are confirmed, or you can skip the prompt and directly execute step 303 after detecting the existence of the upgrade package.

[0065] Step 303: Load the application upgrade package into the running memory and guide the application to upgrade according to the contents of the application upgrade package.

[0066] By using the bootloader's application upgrade function, the application is taken to the upgrade page and upgraded according to the application upgrade package.

[0067] It should be noted that since the data in the application upgrade package is the difference between versions, the differential upgrade method is used, which results in a faster upgrade speed and reduces the space occupied by the application upgrade package and the upgrade process.

[0068] The third embodiment of the present invention relates to a system for launching an application, such as... Figure 4 As shown, it includes:

[0069] The receiving module 401 is used to obtain user demand information and hardware information of the IoT device through the client;
