[0032] Embodiment 1

[0033] Figure 1 A flow chart of a method for online upgrading of a programmable logic device provided in the first embodiment of the present invention is applicable to the case of upgrading or updating a CPLD. The method can be executed by an online upgrading device for a programmable logic device, wherein the device can be implemented by software and / or hardware and is generally integrated on an electronic device. In this embodiment, the electronic device includes but is not limited to: an industrial computer motherboard and other devices.

[0034] like Figure 1 As shown, a method for online upgrading of a programmable logic device provided in Embodiment 1 of the present invention is applied to an industrial computer mainboard, and includes the following steps:

[0035] S110: Acquire source data of a data packet to be upgraded of a programmable logic device.

[0036] Among them, a programmable logic device is an integrated circuit chip that can be reprogrammed according to user needs to achieve different logical functions. A programmable logic device has the characteristics of strong flexibility and reusability, and is a semi-custom circuit in a digital electronic system. The type of the programmable logic device in this embodiment may be CPLD. The data packet to be upgraded may be a data packet related to the upgrade of the programmable logic device. The source data may refer to data directly from a source file, or "copy data" directly copied from a source file. The source data in this embodiment may be understood as text source data of the data packet to be upgraded.

[0037] In this embodiment, the industrial computer motherboard can obtain the source data of the data packet to be upgraded of the programmable logic device. The industrial computer motherboard can be a COME (COM Express) modular motherboard. COM Express is a computer module standard defined by the International Industrial Electrical Association. This modular motherboard integrates core functional components such as the central processing unit (CPU), chipset and memory, making it equivalent to a simplified computer system. Through dedicated interfaces, these motherboards can be seamlessly connected with other components to further expand their functions and form a complete computer system.

[0038] S120: Select part of the data from the source data as data packets to be sent.

[0039] The data packet to be sent may be a data packet that needs to be sent to a programmable logic device.

[0040] In this embodiment, a portion of data may be selected from the data packets to be sent as the data packets to be sent.

[0041] S130, sending the data packet to be sent to the programmable logic device, and determining the sending result.

[0042] The sending result may include sending success or sending failure.

[0043] In this embodiment, the mainboard of the industrial computer may send the data packet to be sent to the programmable logic device, and determine the sending result of the data packet to be sent.

[0044] S140: When the sending result is successful, continue to obtain new data packets to be sent from the source data and send them until all source data in the data packets to be upgraded are sent.

[0045] In this embodiment, when the sending result is successfully sent, it means that the data packet to be sent is successfully sent to the programmable logic device. At this time, a new data packet to be sent can be obtained from the source data and sent until all source data in the data packet to be upgraded are sent. In this embodiment, the sending result is determined each time the data packet to be sent is sent, so that the programmable logic device can successfully receive the data each time, thereby ensuring the stability of data transmission.

[0046] A method for online upgrading of a programmable logic device provided in a first embodiment of the present invention includes: obtaining source data of a data packet to be upgraded of a programmable logic device; selecting part of the data from the source data as a data packet to be sent; sending the data packet to be sent to the programmable logic device and determining the sending result; when the sending result is a successful sending, continuing to obtain new data packets to be sent from the source data and sending them until all the source data in the data packet to be upgraded are sent. The method sends the data in the data packet to be upgraded to the programmable logic device respectively, and determines whether the sending result is a successful sending each time, and continues to send other data only after the sending is successful, which can improve the stability of data transmission and solve the problem of poor stability of data transmission when upgrading CPLD in the prior art.

[0047] Based on the above embodiment, a variant embodiment of the above embodiment is proposed. It should be noted that in order to make the description concise, only the differences from the above embodiment are described in the variant embodiment.

[0048] In one embodiment, selecting part of the data from the source data as the data packet to be sent includes: determining the number of sendable bytes based on the number of receivable bytes of the programmable logic device; selecting data of a corresponding number of bytes from the source data based on the number of sendable bytes, and using the data as the data packet to be sent.

[0049] The number of receivable bytes may refer to the number of bytes that the programmable logic device can receive simultaneously, and the number of transmittable bytes may refer to the number of bytes that the transmitted data may include.

[0050] In this embodiment, the number of bytes that can be received can be determined according to the actual structure of the programmable logic device, and the number of bytes that can be received can be used as the number of bytes that can be sent. The industrial computer motherboard can determine how many bytes can be included in each data packet sent according to the number of bytes that can be sent, and select data with the same number of bytes as the number of bytes that can be sent from the source data, and use the selected data as the data packet to be sent. For example, if the number of bytes that can be sent is 16 bytes, 16 bytes of data are read from the source data each time as the data packet to be sent.

[0051] Embodiment 2

[0052] Figure 2This is a flow chart of a method for online upgrading of a programmable logic device provided in the second embodiment of the present invention. The second embodiment is optimized on the basis of the above embodiments. For details not yet provided in this embodiment, please refer to the first embodiment.

[0053] like Figure 2 As shown, a method for online upgrading of a programmable logic device provided in Embodiment 2 of the present invention comprises the following steps:

[0054] S210: Acquire source data of a data packet to be upgraded of a programmable logic device.

[0055] S220: Select part of the data from the source data as data packets to be sent.

[0056] S230: Determine whether the data packet to be sent is stored in a specified address of the programmable logic device.

[0057] The designated address may be the address of the data packet to be sent when it is stored in the programmable logic device.

[0058] In this embodiment, the address of the data packet to be sent when it is stored in the programmable logic device can be specified in advance.

[0059] S240. Send the data packet to be sent and the corresponding designated address to the programmable logic device through the current line for data transmission with the programmable logic device, so that the programmable logic device stores the data packet to be sent to the address corresponding to the designated address.

[0060] The current line may be a line currently used to transmit data.

[0061] In this embodiment, when the data packet to be sent is sent to the programmable logic device, a corresponding designated address may also be sent so that the programmable logic device stores the data packet to be sent at an address corresponding to the designated address.

[0062] In this embodiment, data can be transmitted through an integrated circuit bus (Inter-Integrated Circuit, I2C), which is a serial communication bus that uses a multi-master-slave architecture and is widely used for communication between microcontrollers and sensor arrays, displays and other devices. The circuit of this embodiment can be implemented by installing a driver. For example, an I2C driver can be installed to perform data transmission.

[0063] S250, determining the sending result; when the sending result is successful, continue to obtain new data packets to be sent from the source data and send them until all source data in the data packets to be upgraded are sent.

[0064] A method for online upgrading of a programmable logic device provided in the second embodiment of the present invention specifically sends the data packet to be sent to the programmable logic device, including: determining that the data packet to be sent is stored at a specified address of the programmable logic device; sending the data packet to be sent and the corresponding specified address to the programmable logic device through the current line for data transmission with the programmable logic device, so that the programmable logic device stores the data packet to be sent at the address corresponding to the specified address. By determining that the data packet to be sent is stored at the specified address of the programmable logic device, this method can conveniently obtain the corresponding data packet from the specified address when determining the sending result, which can improve the efficiency of determining the sending result.

[0065] In one embodiment, determining the sending result includes: obtaining a received data packet corresponding to the data packet to be sent from the programmable logic device; comparing whether the data in the received data packet is consistent with the data in the data packet to be sent, and obtaining the sending result.

[0066] The received data packet may be data stored locally after the programmable logic device receives the data packet to be sent.

[0067] In this embodiment, since the programmable logic device stores the received data packet at the address corresponding to the specified address, this embodiment can directly obtain the received data packet corresponding to the data packet to be sent from the programmable logic device according to the specified address, and compare whether the data in the received data packet and the data packet to be sent are consistent, thereby obtaining the sending result. When the data are consistent, the sending result is a successful sending, and when the data are inconsistent, the sending result is a sending failure.

[0068] In one embodiment, the method further includes: when the sending result is a sending failure, if the number of sending failures does not exceed a line replacement threshold, reinitializing the current line for data transmission with the programmable logic device, and resending the data packet to be sent through the initialized current line; when the sending result is a sending failure, if the number of sending failures exceeds a line replacement threshold, using the backup line as a new current line, and resending the data packet to be sent through the new current line.

[0069] The line replacement threshold may be the number of line replacements, and the line replacement threshold may be set according to actual conditions. The standby line may be a line other than the current line. In this embodiment, there may be multiple lines for data transmission, and the specific number may be set according to actual conditions. Initialization refers to the process of reinstalling the driver corresponding to the line. For example, when the line is I2C, initialization may refer to the process of uninstalling the I2C-n driver (multiple drivers of I2C) and reinstalling the I2C-n driver.

[0070] In this embodiment, when the sending result is a sending failure, if the number of sending failures of the data packet to be sent does not exceed the line change threshold, the current line is reinitialized, and the data packet to be sent is resent through the initialized current line; if the number of sending failures exceeds the line change threshold, it means that there may be a problem with the current line and the line needs to be replaced. Specifically, the backup line can be used as the new current line, and the data packet to be sent can be resent through the new current line.

[0071] In this embodiment, if the line of the data packet to be sent has been changed once, but the number of sending failures after the line change exceeds the line change threshold, the line can be changed again or an error can be reported directly, which is not limited in this embodiment.

[0072] This embodiment can prevent the problem of being unable to scan the device connected to the communication line due to frequent errors in the communication line (such as I2C) by changing the transmission line when the number of transmission failures is too many.

[0073] In one embodiment, the method further includes: if the sending of the data packet to be sent has changed the current line, and the number of sending failures after the change exceeds the abnormal number, then stopping the sending of the data packet to be sent and issuing an alarm message.

[0074] The number of abnormalities may be the same as or different from the line replacement threshold. The alarm information may be in the form of sound or indicator light, etc., which is not limited in this embodiment.

[0075] In this embodiment, if the number of failed transmissions of the data packet to be transmitted after the line is replaced exceeds the number of abnormal transmissions, it indicates that the replaced line may also have abnormalities. At this time, it is necessary to stop the transmission of the data packet to be transmitted and issue an alarm message to prompt relevant staff. In this embodiment, after the data packet fails to be transmitted, it can be determined whether to resend the data packet according to the number of failed transmissions. When the number of failed transmissions does not exceed a certain number, the upgrade will not be stopped, but the data packet will be resent, thereby solving the problem of cumbersome operation and complex upgrade caused by the need to re-program the programmable logic device once the upgrade fails in the prior art.

[0076] In one embodiment, the method further includes: when the sending result is a sending failure, recording an error log at the time of the failure; the error log at least includes an error line identifier, an error address, and an error data packet.

[0077] The error log may be a log recording relevant information of a data packet failure. The error line identifier may be an identifier of a line used when the data packet fails to be sent, the error address may be an offset position of the data packet that fails to be sent in the source data, and the error data packet may include a data packet to be sent and a data packet that has been received by the programmable logic device.

[0078] In this embodiment, when the sending result of the data packet to be sent is a sending failure, an error log at the time of the failure may be recorded, and the error log may include relevant information such as an error line identifier, an error address, and an error data packet.

[0079] The embodiments of the present invention provide several specific implementation methods based on the technical solutions of the above embodiments.

[0080] As a specific implementation method of this embodiment, Figure 3 The present invention provides a flowchart of a method for online upgrading of a programmable logic device. In this embodiment, the mainboard of the industrial computer is COME, the programmable logic device is CPLD, and the line for transmitting data is I2C. Figure 3 As shown in the figure, after determining that the CPLD needs to be upgraded, the I2C driver can be installed to ensure smooth data interaction between COME and CPLD. COME detects the CPLD to confirm its existence and status. Calculate the amount of data transmitted: Calculate the amount of data transmitted, and 16 bytes can be transmitted at a time. Each time COME transmits a 16-byte data packet to the CPLD through the I2C bus.

[0081] This embodiment adds a data verification function, by comparing the sent data packet with the received data packet of the CPLD, to check whether the sent data is successful. If the data packet transmission fails, the error log is recorded, and it is determined whether the sent data packet is retransmitted more than 3 times through the backup line. If so, the transmission is stopped and an alarm is issued; otherwise, the current I2C bus is reinitialized, and it is continued to determine whether the number of retransmissions on the current I2C bus exceeds 3 times. If so, the backup line is switched and initialized, and the subsequent steps of retransmitting data are continued; otherwise, the subsequent steps of retransmitting data are directly performed.

[0082] When it is confirmed that all data has been sent successfully, the data sending is completed.
