[0034] Preferably, all undefined variables in the present invention, if not clearly defined, can be manually set thresholds.
[0035] The present invention provides a universal automatic burning control system, the system comprising: Interface control module and burning control module; Wherein, the interface control module is used to draw and refresh the user operation interface of the system, and the user operation interface is used to accept user input and display burning information; The interface control module also includes a firmware processing module; the firmware processing module is used to load a firmware file, calculate the checksum of the firmware file and compare it with the checksum in the INI configuration file; The burning control module includes a firmware burning module and a log module; the firmware burning module is a burner, and the burner is used to communicate with the chip to be flashed; the log module is used to store the burning log.
[0036] Furthermore, the user operation interface includes a port setting area, a receiving control area, an information display area, and a burning control area.
[0037] Preferably, the port setting area is used to set the ports of the burning channels and display the connection status of each burning channel.
[0038] Preferably, the receiving control area is used to load a firmware file or save a read-back file.
[0039] Preferably, the information display area is used to display logs and error information during operation of the system.
[0040] Preferably, the burning control area is used to load an INI configuration file, display the configuration information of the chip to be flashed, load the verification code of the firmware file corresponding to the flashing chip, and compare the verification code of the firmware file corresponding to the flashing chip with the verification code of the firmware file configured in the INI configuration file.
[0041] Preferably, the burning control area is also used to display the burning progress of the corresponding firmware file burned by the flash chip.
[0042] A universal automatic burning control system, when starting to run, the interface control module is controlled by the UI thread, and the burning control module is controlled by the burning thread.
[0043] The UI thread is used for: creating interface controls; reading, parsing and displaying INI configuration files; interactive input and saving of the interface, and displaying the burning process.
[0044] The burning thread is used for: implementation of the burning function, analysis of targeted projects, and other operations related to the burning chip operation.
[0045] After the system starts running and the interface initialization is completed, the UI thread starts the form loop and begins to capture external response signals.
[0046] The external response signal can be a touch screen trigger, a mouse click, a keyboard trigger or an external button.
[0047] When triggered by an external response signal, it starts reading the configuration: Read all QR codes in the INI configuration file and parse the relevant parameters in the INI configuration file, and display them in the corresponding position of the interface; perform port scanning and open the corresponding port; Get the QR code from the mark on the chip or the production schedule, and determine whether the current INI configuration file has a configuration option corresponding to the QR code. At the same time, the UI thread refreshes the information and error information (if any) of the corresponding area. If the current INI configuration file does not have the configuration option of the QR code, exit the burning process.
[0048] The configured verification code and firmware information are displayed according to the obtained QR code; Click the burn button on the UI thread interface to obtain port control, create a burn thread, set relevant parameters, and start the burn thread. Specifically: Get the port control right, open the port, disable other irrelevant controls, set the operation type, and determine whether the burning thread object exists. If the port control acquisition or opening fails, or the burning thread exists, end the signal response and prompt an error.
[0049] The operation type includes: burning, blank detection, CRC readback, or a combination of operations, such as performing a CRC readback check after burning, or performing a blank detection before burning, resetting or setting the chip to zero, etc.
[0050] Furthermore, the burning thread initializes the chip channel corresponding to the current QR code: The burning thread loads the firmware of the current QR code, calculates the firmware's checksum and compares it with the checksum of the corresponding firmware in the INI configuration file; determines whether the current burner supports the selected firmware / chip.
[0051] Furthermore, the burning thread communicates with the MES system to obtain the release status of the selected firmware and whether to approve the flashing of the selected firmware. If not approved, the burning process is exited. The purpose of this step is that some firmware requires authorization and distribution of unique identification numbers, so it is necessary to communicate with the manufacturer's MES system for registration and traceability. Some chips have unique identification numbers, which can also be uploaded to the system for unified management to generate unique firmware.
[0052] Further, the burning thread enters the burning process, and the UI thread refreshes the information and error information (if any) of the corresponding area.
[0053] Among them, an INI configuration file may include one or more QR code information, one QR code information may correspond to one or more chip channels, and one channel may burn / extract / verify one or more firmware.
[0054] Preferably, all undefined variables in the present invention, if not clearly defined, can be manually set thresholds.
[0055] The general automatic burning control system can be run on computing devices such as desktop computers, laptops, PDAs, and cloud servers. The general automatic burning control system can include, but is not limited to, processors and memories. Those skilled in the art can understand that the example is only an example of a general automatic burning control system and does not constitute a limitation on a general automatic burning control system. It can include more or less components than the example, or combine certain components, or different components. For example, the general automatic burning control system can also include input and output devices, network access devices, buses, etc.

[0057] The memory can be used to store the computer program and / or module, and the processor realizes various functions of the universal automatic burning control system by running or executing the computer program and / or module stored in the memory, and calling the data stored in the memory.
