Initializing the power-on, the chip rewriting device is powered on, initializing the chip to rewrite the storage 

space and the expansion interface of the device, and mounting the file in the storage space to the file system 

of the chip rewriting device;

The upper computer is connected to detect whether the upper computer is connected to the expansion int-

erface;

State judgment, the monitor chip rewrites the device state, and determines whether the chip rewrites the d-

evice state to allow data upgrade;

nd the external extended storage medium is specifically an SD card or a TF card or a USB flash drive or a mo-

bile hard disk.

Further, the step of power-on initialization is specifically: initializing an SD card, mounting the SD card to a fil-

e system of the chip rewriting device, initializing the USB, and enumerating the USB MASS STORAGE.

Further, the step state determination is specifically: determining whether the upper computer file reception 

is completed, and then jumping to determine whether the upper computer connection is disconnected, othe-

rwise returning to receive the incomplete identification and waiting for the reception to be completed; dete-

rmining whether the upper computer connection is off On, yes, return the connection disconnection flag and 

wait for reconnection, otherwise jump to the step upgrade judgment.

Further, before the step data update, the data verification is further included, and the upgrade data is verified. 

If the upgrade data passes the verification, the process jumps to the step data update, and if the upgrade data 

fails the verification, the data error message is returned. .

le, and the step data verification specifically adopts a CRC check.

Compared with the prior art, the beneficial effects of the present invention are:

The present invention provides a data upgrading method for a chip rewriting device, including the steps of po-

wer-on initialization, host connection detection, parsing data, state determination, upgrade judgment, upgrad-

e file decryption, and data update; the present invention also relates to an electronic device and a readable sto-

rage medium, A data upgrade method for executing a chip rewriting device. The invention separates the progra-

m and the data in the chip rewriting device, and uses the programming interface to separately upgrade and upd-

ate the program and data in the chip rewriting device. The data upgrading method of the invention is flexible an

d changeable, saves the upgrade cost, and reduces the difficulty of upgrading. At the same time, the upgrade me-

thod is simple to operate, and the flexible updating and upgrading of the chip rewriting device is realized.

The above description is only an overview of the technical solutions of the present invention, and the technical 

means of the present invention can be more clearly understood and can be implemented in accordance with the 

contents of the specification. Hereinafter, the preferred embodiments of the present invention will be described 

in detail with reference to the accompanying drawings. Specific embodiments of the present invention are given

 in detail by the following examples and the accompanying drawings.

Detailed ways

The present invention will be further described in conjunction with the accompanying drawings and specific embo-

diments. It should be noted that, without conflict, the embodiments described below may be arbitrarily combined 

to form a new embodiment. .

The data upgrading method of the chip rewriting device, as shown in FIG. 1, includes the following steps:

Initializing the power-on, the chip rewriting device is powered on, initializing the chip to rewrite the storage space 

and the expansion interface of the device, and mounting the file in the storage space to the file system of the chip 

rewriting device;

The upper computer is connected to detect whether the upper computer is connected to the expansion interface;

Parsing the data, the chip rewriting device parses the data packet of the extended interface; the specific use of the 

USB protocol stack to parse the data packet;

State judgment, the monitor chip rewrites the device state, and determines whether the chip rewrites the device 

state to allow data upgrade;

The upgrade judgment determines whether there is an upgrade file in the file system of the chip rewriting device; 

specifically, whether the upgrade file exists in the root directory of the file system of the scan chip rewriting device, 

generally, the version number of the upgrade file is detected, for example, the version number is high. In the exist-

ing file version, it is determined that there is an upgrade file;

Decrypting the upgrade file, obtaining the upgrade file, and decrypting the upgrade file to obtain upgrade data;

The data is updated, and the upgrade data is updated to the chip rewriting device through a programming interf-

ace.

In an embodiment, the storage space includes an internal storage medium and an external extended storage med-

ium; the external extended storage medium is specifically an SD card or a TF card or a USB flash drive or a mobile 

hard disk, and the expansion interface is specifically a USB. As shown in Figure 2, the step of power-on initializat-

ion is as follows: Initialize the SD card, delay and wait for the SD card to load. If the SD card is not properly loaded, 

the SD card is incorrect. If the SD card is successfully read, the SD card is mounted to the chip. Rewrite the file sys-

tem of the device; initialize the USB, and enumerate the configuration USB MASS STORAGE. Specifically, the host 

computer is the PC end, and check whether the PC end is connected to the chip rewriting device through the USB 

connection.

As shown in FIG. 4, the programming interface is specifically an IAP interface, and the data in the chip rewriting de-

vice is mainly divided into three types, an underlying program, an application program, and an authorization count-

ing file; wherein the bottom layer program is a factory setting, and the device cannot be changed after being put in- 

to use. The application and authorization count file users are upgraded at the terminal via USB.

In an embodiment, as shown in FIG. 2, the step state determination is specifically: determining whether the upper 

computer file reception is completed, and then jumping to determine whether the upper computer connection is d-

isconnected, otherwise returning to receive the incomplete identification and waiting for the reception to be comp-

leted; Determine whether the connection of the upper computer is disconnected. If yes, return to the connection d-

isconnection identification and wait for reconnection, otherwise jump to the step upgrade judgment.

In an embodiment, before the step data update, the data check is further included, and the upgrade data is verified. 

If the upgrade data passes the check, the process jumps to the step data update, and if the upgrade data does not p-

ass the check, the data error message is returned. Specifically, the step upgrade file decryption specifically uses AES 

to decrypt the upgrade file, and the step data verification specifically adopts the CRC check. For example, the autho-

rization counting file will be encrypted before leaving the factory. Generally, the AES algorithm and the CRC algorit-

hm are used to encrypt the authorization counting file, which is converted into the cipher text format and sent to the 

terminal client. When the chip rewriting device reads the authorization counting file, the first The authorization cou-

nt file is decrypted by AES. After decryption, the data is CRC-checked again. After the verification is passed, the auth-

orization count file is upgraded.

ry and configured to be executed by the processor, the program comprising a data upgrading method for executing the 

chip rewriting device; A storage medium on which is stored a computer program, and the computer program is execut-

ed by the processor to perform a data upgrading method of the chip rewriting device.
