[0035] Embodiment 1

[0036] As shown in Figures 1 to 4 , a method of automatic updating of embedded application firmware in an embodiment of the present application is introduced, which comprises the following steps.

[0037] In step S101, configuration information is added to the application firmware in the application firmware library.

[0038] As shown in Figure 2 , in the application firmware library (a group of application firmware files in a fixed folder), all possible application firmware (with extension.bin) is placed, the software for adding configuration information is opened, the fixed format configuration file is read, and the fixed format configuration file includes but is not limited to chip name, chip ID, and chip series ID; the hardware configuration file (hardware version information) is read according to the hardware version number of the burning device, and each hardware corresponds to a hardware configuration file; the application firmware which wants to add configuration information is read from the application firmware library, and the information read above is displayed on the operation interface (as shown in Figure 3 ).

[0039] Select the corresponding hardware version and chip series on the operation interface, and add a package to the application firmware according to the information collected in the above steps, wherein the package includes but is not limited to: (1) a 4-byte communication header, (2) a 2-byte file version, (3) a 2-byte series ID, (4) a 4-byte current date and time information, (5) a 512 address starting to store 64 hardware version lists, and (6) a 768 address starting to store 128 chip lists. Finally, generate an application firmware file with a corresponding extension according to the hardware version number.

[0040] A hardware version list is formed in a fixed format for adding firmware configuration information; different devices set the version number in the hardware list; and configuration information is added according to the firmware generation date, generation version, whether it is special firmware, and the corresponding hardware version.

[0041] In this embodiment, the burning device has a hardware version number that can be read, and the application firmware has a part of the necessary communication protocol, such as reading the hardware version number and uploading it to the host computer, reading the current application firmware type whether it is a special firmware identifier and uploading it to the host computer, reading the application firmware generation date and uploading it to the host computer, and storing the current compilation time when compiling.

[0042] In step S102, the current application firmware in the burning device is updated according to the hardware version number of the burning device and the configuration information in the application firmware library.
