It should be noted that, the firmware files stored in the server are divided into a general firmware file and a customized firmware file, and the general firmware file is used for loading a standard program and is identified and determined by general identification information. And the custom firmware file cannot be reversed to generate a generic firmware file. The customized firmware file is used for loading the customized program and is determined by specific customized identification information, wherein the standard program can be upgraded into the customized program, and the customized program cannot be reversely returned into the standard program.
In this embodiment, compared with the conventional method, the authentication component and the compiling component are added to the server to authenticate and identify the user identification information input by the user, and the user identification information is selectively compiled, so that different upgrades are performed by selecting the firmware file corresponding to the user identification information, and the updating of the standard firmware file can be performed only when the authorization verification is passed, thereby ensuring the data security. The authentication component matches the user identification information received by the receiving and transmitting component with preset customized identification information, determines target customized identification information, acquires a firmware source program file corresponding to the target customized identification information, and the compiling component compiles the configuration file sent by the receiving and transmitting component and the firmware source program file acquired by the authentication component to automatically generate a customized firmware file, so that a customer can package and shipment after finishing upgrading the customized firmware file after downloading on line, and the customized firmware file is not required to be adjusted subsequently. Therefore, the customized firmware file of the correct receiving card can be quickly identified, the screen configuration data is not lost, the function adaptation is normal after the screen is upgraded, unnecessary maintenance is reduced, the operation is simple, the time consumption is less, and the safety of the customized firmware file is ensured. The method can solve the problems that whether the receiving card firmware file is correctly received or not can not be identified by software upgrading in the traditional scheme, and only the screen can be lightened to check whether the user customized firmware file of the receiving card is correctly received or not after the upgrading is successful, so that the function is not adapted and can not be applied after the upgrading of the card of the same type is not recognized due to the fact that the correctly customized firmware file of the card of the same type is not correctly upgraded.
Preferably, the connection between the server 10 and the display device 20 may be performed by a wired network, a wireless network, or a mobile communication network, and the transceiver component 11 of the server 10 may receive the user ID and the configuration file sent by the display device 20 through any one of the above connection methods, or may download the compiled customized firmware file onto the display device 20 according to the download request of the display device 20 through any one of the above connection methods. Similarly, the general firmware file corresponding to the user identification information stored directly in the server 10 may be downloaded to the display device 20 according to the download request of the display device 20 by any of the above connection methods.

The configuration file includes the following contents: the FPGA model, the light panel map, the light panel parameters, the chip register parameters, and the display parameter table, i.e., the Gamma table, are not limiting. As long as the obtained configuration file can meet the configuration file required by the upgrade of the display device.
The configuration file is a configuration file formed by user configuration information passing through a screen experience verification test in the display device 20, and the screen body can work normally under the condition that the firmware files are matched through the configuration file.
In one embodiment, as shown in fig. 2, the authentication component 13 includes an authentication unit 131 and an acquisition unit 132.
The authentication unit 131 is configured to obtain a preset custom identification information base, match the received user identification information with each custom identification information in the custom identification information base, and determine target custom identification information according to a matching result.
The authentication unit 131 is specifically configured to include:
Judging whether the received user identification information is the same as the customized identification information;
If the customized identification information is the same as the user identification information, determining that the display device is subjected to upgrading configuration in a customized firmware file mode, and generating an instruction of a customized firmware file to the compiling component, wherein the customized identification information is used as target customized identification information;
If all the customized identification information is different from the user identification information, continuing to judge whether the user identification information is the universal identification information or not;
if the user identification information is the universal identification information, determining that the display device is updated and configured in a universal firmware file mode;
if the user identification information is not the universal identification information, the user identification information is illegal information and error prompt is carried out.
That is, verifying whether the user identification information is preset customized identification information; judging whether the user identification information and the custom firmware file are the same, if not, the user identification information is not verified, and the user identification information is not preset custom identification information, and the display device 20 cannot adopt the custom firmware file for upgrading and cannot load the custom program; if yes, the user identification information passes the verification, which indicates that the user identification information is preset customized identification information, and the display device 20 may use the customized firmware file to perform upgrade configuration, and at this time, the customized identification information matched with the user identification information is taken as target customized identification information.
Note that, the authentication unit 131 in the above embodiment further ensures data security by adopting two judgment operations.
In another embodiment, the difference between the authentication unit 131 and the above embodiment is that the data security is improved by only one judgment operation, that is, when the authentication unit 131 judges that the received user identification information is different from all the customized identification information, the judgment of the common identification information is not performed, and it is directly determined that the display device 20 is configured in a common firmware upgrade mode, so that compiling processing is not required, FPGA processing in the update receiving card is not required, operation is simplified, and processing speed is improved.
The obtaining unit 132 is configured to obtain a target firmware source program file corresponding to the target customization identification information according to a preset correspondence between the customization identification information and the firmware source program file and the target customization identification information, and send the target firmware source program file to the compiling component.
The obtaining unit 132 is further configured to directly obtain a general firmware file that matches the user identification information if the user identification information is general identification information, without performing compiling processing, and send the general firmware file to the display device 20 through the transceiver component.
In the embodiment of the present application, the display device 20 adopts an upgrade mode that is divided into a general firmware file upgrade and a custom firmware file upgrade, and the general firmware file upgrade satisfies most of display device upgrades, so as to further improve data security, improve yield, reduce rework, improve user experience, and upgrade an original firmware source program file into a custom firmware file only through authentication verification.
In this embodiment, the authentication component verifies whether the user identification information received by the transceiver component is preset customized identification information, so that security can be improved, the risk of data damage caused by unauthorized operation can be avoided, and customer satisfaction is reduced while unnecessary after-sale service requirements are generated.
Next, after receiving the configuration file and the prompt for verification, the compiling component 12 is specifically configured to:
Updating the identification information in the target firmware source program file to target customized identification information; the identification information is a user ID, i.e. version number information.
And compiling the configuration file and the updated target firmware source program file to generate a customized firmware file.
In this embodiment, since the configuration information in the configuration file of the receiving card is written into the RAM and/or the register in the FPGA and the like, when the server compiles the firmware source program file, the configuration initial value after powering on the receiving card can be determined through the configuration file, after receiving the uploaded configuration file, the information of the configuration file of the receiving card is packaged and integrated into the corresponding project configuration file, then the compiling work of the firmware source program file is performed through the FPGA, the custom firmware file containing the configuration information of the configuration file is generated, and the user ID stored in the custom firmware file is changed to be the custom ID, and the custom firmware file can be downloaded by the user through the internet after being generated. The FPGA development tool provides relevant development technologies such as logic locking, user reconfiguration and the like, and can effectively ensure the integrity and the safety of the customized firmware file generated by the invention.
After the compiling component 12 generates the customized firmware file, the customized firmware file and the target customized identification information are also stored in association. In this way, when the user inputs the same user identification information again, the server recognizes that the customized firmware file corresponding to the user identification information is already stored in the database through the association relationship, so that compiling processing is not required again, and the stored customized firmware file is directly acquired and sent to the display device 20 for upgrading configuration.
The FPGA firmware source program file of the core is stored in the manufacturer server, and is protected from illegal intrusion and acquisition by authorized protective measures such as hardware firewall, user authentication and the like, so that the maximum flexibility of the customized firmware file configurable by the user is provided while the core intellectual property of the LED control system manufacturer is effectively ensured.
In order to better understand the technical scheme of the application, century application scene description of the FPGA system customized by a user is exemplified, and the method comprises the following steps:
The field engineer inputs a user ID into the LED display screen through a computer to log in the server, and uploads a configuration file to the server. The server receives the user ID and the configuration file sent by the display device through the receiving and transmitting component. The authentication component verifies whether the user ID received by the receiving and transmitting component is a preset customized ID, if the user ID passes the verification, a firmware source program file corresponding to the preset customized ID is obtained from a preset firmware source program file library, the compiling component automatically loads a customized program, and the configuration file sent by the receiving and transmitting component and the firmware source program file obtained by the authentication component are compiled to automatically generate a customized firmware file. The field engineer downloads the customized firmware file containing the configuration file information of the receiving card from the server through the display device, and updates the customized firmware file to the nonvolatile storage space of the FPGA in the receiving card by using the firmware upgrading program. Before the upgrade operation is performed, the firmware upgrade program checks the user ID of the existing firmware of the receiving card, and performs the following operations: and verifying whether the user ID is the preset customized ID, if so, upgrading the customized firmware file, and if not, upgrading the universal firmware file without executing the customized firmware file. The security of the firmware file is ensured by such a comparison operation. And after the screen body customized firmware file is updated, the screen body customized firmware file can be packaged and shipped without subsequent adjustment.

The method can solve the problems that whether the receiving card firmware file is correctly received or not can not be identified by software upgrading in the traditional scheme, and only the screen can be lightened to check whether the user customized firmware file of the receiving card is correctly received or not after the upgrading is successful, so that the function is not adapted and can not be applied after the upgrading of the card of the same type is not recognized due to the fact that the correctly customized firmware file of the card of the same type is not correctly upgraded.
Preferably, the user identification information includes a user ID, and the customized identification information includes a customized ID.
The user identification information is used for distinguishing whether the FPGA firmware file version of the product is a standard (factory) version firmware file or a customized version firmware file, wherein the standard version firmware file can be upgraded into the customized version firmware file, but the customized version firmware file cannot be reversely returned into the standard version firmware file.
