In order to facilitate understanding of the chip burning method of the present application, a system architecture diagram of an upper computer is provided in an embodiment of the present application. As shown in fig. 1, the system architecture of the upper computer includes a communication module, a data processing module, a system control module and a user interface module. The communication module CAN be compatible with different communication protocols, such as a controller area network (Controller Area Network, CAN) communication protocol, an asynchronous transmission standard interface communication protocol (RS 232/RS 285), a transmission control protocol/interconnection protocol (Transmission Control Protocol/Internet Protocol, TCP/IP) and the like, by defining an interface specification of each communication protocol. If the chip supports multiple communication protocol standards, the communication module can adapt to multiple series of chips for burning. The communication module can have the functions of starting the communication channel and closing the communication channel, can also have the function of configuring communication parameters, and can also receive and transmit communication data. The data processing module can have the function of initializing a data model, can analyze data, and can encapsulate the function of transmitting the data. The system control module can burn or erase the file, read the file, convert the file, check and transmit data. The user interface module can control the display function and the lower computer (such as a chip) burning function.

In the system architecture of fig. 1, the communication protocols of these data transmissions (CAN communication protocol, RS232/RS285, TCP/IP) are very different in terms of physical links, transmission rules, etc. According to the embodiment of the application, the interface specifications of each communication protocol are unified on the software level of the upper computer, foolproof treatment measures are effectively taken, the condition processing such as filtering, limiting and checking can be conducted in the data transmission process aiming at a certain specific communication protocol, and the corresponding communication interface is expanded only by being realized on the basis of formulating the specifications, so that the expansion is easy. Each data transmission communication protocol is isolated on the communication channel and independent, and the transmission process is identified and processed by the system control module according to the mutual characteristics.

Unifying the interface specifications for each communication protocol: the rules, data structures for each communication protocol may be unified. For example, for the CAN protocol, there are how many bits each frame is transmitted, what each bit means, etc. Each transport protocol is unified in accordance with such specifications.

The communication module of the upper computer shown in fig. 1 can be compatible with various communication modes, and can effectively process errors in the communication process according to protocol communication flow requirements in the chip communication process, so that whether each operation is successful or not can be ensured, and a corresponding return result can be obtained. The man-machine interaction function can be added through the user interface module, and the change of the state parameters in the process of communication burning can be intuitively and obviously displayed. The upper computer is flexible in interface of external expansion, and can perform encapsulation analysis aiming at different types of chip burning file formats so as to adapt to different data models.

For related developers and testers, when the communication of multiple functional schemes and multiple communication protocols is involved, the problem of compatible matching of the communication of each functional scheme does not need to be analyzed in a time-consuming manner, and the testers do not need to use time to build a complicated environment and complicated steps.

The burning driver is mainly used as a bridge for receiving the burning data part by the system control module and the lower computer, and after the packaged burning data is obtained from the system control module, the data is continuously transmitted to the lower computer in frames according to the matching rule of the lower computer, and meanwhile, the state of the data transmission process is transmitted to the user interaction part. 5. The user interaction module comprises display information and man-machine interaction, is a user operation input port and is used for responding to the command and displaying the processing result.

The burn-in driver process is shown in fig. 9. The overall design concept of the data processing and recording part and the system control part is similar to that of the CAN communication module, and is not repeated here. The main difference between the controller and the CAN communication module is the burning driver part, and the burning driver part is particularly important in the RS232/RS485 module. The burning driver receives the burning data transmitted from the system control part, the burning driver starts and monitors all the time after receiving the first frame signal, and after waiting for a specific time period, if the received data is found to be incomplete, the burning driver transmits information to the system control part all the time until receiving the finished signal. If the received data does not accord with the check rule, the burning driver sends a resending signal to the system control part, and after waiting for a corresponding answer, the burning driver clears the received error data and resets to a starting state. After the complete burning data is received, the user interaction part and the lower computer part are given to send waiting ready information, after the starting signal of the lower computer is reached, the burning driver can send the burning data to the lower computer in frames according to a rule which is negotiated with the lower computer in advance, and meanwhile, the signal data of the response state is also transmitted to the user interaction interface.

The TCP/IP burning relation chart is shown in FIG. 10. The TCP/IP Ethernet is communicated, which has a certain internal hardware requirement on the burnt chip and requires the chip to support the relevant TCP/IP network communication protocol. The whole function process of the TCP/IP burning module is similar to the RS232/RS485 communication process. The flow of the TCP/IP burn of FIG. 9 may involve several modules: the system comprises a TCP/IP protocol communication module, a system control module, a data processing module, a network adapter, a data distributor, a lower computer and a user interaction module. The difference is in the network adapter and the data distributor. The network adapter is used for receiving the burnt data which is processed by the burnt file and is completed by the system control module, and after the burnt data is received, returning information to the system control module and suspending the sending of the data; after the data is received, the network adapter issues a command to inform the lower computer to search the network node and transmit the relevant network connection information back to the network adapter, after the network state information is obtained, the user interaction module is informed, the interface displays the relevant state information and starts to transmit the data to the data distributor. The data distributor is a bridge transversely connected with the network adapter and the lower computer and is used for receiving the burnt data, the data are placed in a storage area with a queue structure, after the reception is finished, the burnt data in the storage area are sent to the lower computer according to a certain matching rule, and the matching rule is that the data distributor and the lower computer are mutually agreed in advance, so that the purpose of quickly interacting the data is achieved. After the lower computer receives the completed burning data, the corresponding state is transmitted to the user interaction while the burning is carried out, and the corresponding state information is used for displaying the related state information in real time.
