Description
Technical Field
The invention relates to an intelligent network card and an FPGA firmware updating management method of the intelligent network card, in particular to an intelligent network card and an FPGA firmware updating management method thereof, which update the firmware of an FPGA by matching a CPU module of the intelligent network card with a multiplexer.
Background
In the circuit architecture of the server, a Baseboard Management Controller (BMC) is usually used to assist other ICs in managing the FLASH ROM, for example, operations such as online update of firmware (firmware) are performed, however, since a general standard intelligent network card is usually only provided with two chips such as a CPU and an FPGA, the server motherboard is not provided with the BMC to manage the FLASH ROM.
The FPGA has the greatest characteristic that the function of the combinational logic can be edited according to the requirement of a user, so that the firmware of the FPGA is stored in the FLASH ROM, and is loaded into the FPGA for setting when the FPGA is started to operate.
As mentioned above, because the existing intelligent network card does not have a BMC to manage and control the FLASH ROM of the FPGA, when the firmware of the FPGA needs to be updated, the firmware stored in the FLASH ROM often needs to be updated through the FPGA, and the FPGA cannot operate effectively, or even stops operating.
Disclosure of Invention
In view of the fact that in the prior art, the existing intelligent network card is not provided with the BMC, when the FLASH ROM of the FPGA needs to update the firmware, the firmware of the FLASH ROM can be updated only through the FPGA, but the firmware of the FLASH ROM is updated through the FPGA, so that the FPGA cannot normally operate; accordingly, the present invention is directed to an intelligent network card and an FPGA firmware update management method for the intelligent network card, which can update firmware of a FLASH ROM under normal operation of an FPGA module through control of a CPU module and a multiplexer.
The present invention provides an intelligent network card for solving the problems of the prior art, wherein the intelligent network card is installed on a server host, and the intelligent network card comprises a flash memory, a multiplexer, an FPGA module and a CPU module.
The flash memory stores an existing firmware data. The multiplexer is electrically connected to the flash memory. The FPGA module is electrically connected to the multiplexer, the multiplexer is preset to be in communication connection with the flash memory and the FPGA module in a preset working mode, so that the FPGA module loads the existing firmware data from the flash memory through the multiplexer in the preset working mode, and sends out a setting completion signal after a firmware setting operation is completed according to the existing firmware data.
The CPU module is electrically connected with the server host, the FPGA module and the multiplexer, and is used for entering an updating working mode when receiving a setting completion signal sent by the FPGA module and firmware updating information sent by the server host, sending a first switching signal to the multiplexer when the working mode is updated, enabling the multiplexer to be switched into a communication connection flash memory and the CPU module, sending the firmware updating information to the flash memory through the multiplexer, sending a second switching signal to the multiplexer after the existing firmware data is updated into a new version of firmware data, and enabling the multiplexer to be switched back to the communication connection flash memory and the FPGA module.
Optionally, the CPU module further includes an SPI interface electrically connected to the multiplexer. Preferably, the CPU module further includes a CPU processing unit electrically connected to the SPI interface, and when receiving the firmware update message sent by the server host, the CPU processing unit sends the first switching signal to the multiplexer through the SPI interface, so that the multiplexer is switched to the SPI interface communicatively connecting the flash memory and the CPU module.
Optionally, the FPGA module further includes a QSPI interface, and the QSPI interface is electrically connected to the multiplexer. Preferably, the FPGA module further includes an FPGA processing unit electrically connected to the QSPI interface, and the FPGA processing unit loads the existing firmware data or the new firmware data from the flash memory through the QSPI interface and the multiplexer, and sends a setting completion signal to the CPU module after completing the firmware setting operation according to the existing firmware data or the new firmware data.
Based on the same inventive concept, the invention also provides an FPGA firmware update management method of the intelligent network card, which comprises the following steps: firstly, step (A) is to start up an FPGA module to load an existing firmware data from a flash memory through a multiplexer to perform a firmware setting operation, and to send a setting completion signal to a CPU module after the firmware setting operation is completed.
Then, step (B) is that the CPU module enters an updating working mode when receiving the setting completion signal sent by the FPGA module and firmware updating information sent by the server host, and sends a first switching signal to a multiplexer when the updating working mode is carried out, so that the multiplexer is switched to be in communication connection with the flash memory and the CPU module, and the firmware updating information is sent to the flash memory through the multiplexer.
Then, in step (C), after the existing firmware data is updated to a new firmware data, the CPU module sends a second switching signal to the multiplexer, so that the multiplexer is switched back to the communication connection of the flash memory and the FPGA module.
Optionally, after the step (C), the FPGA module further loads new firmware data from the flash memory through the multiplexer to perform a firmware resetting operation. Preferably, the FPGA module sends a reset completion signal to the CPU module after the firmware reset operation is completed.
As described above, the present invention uses the CPU module to receive the firmware update information transmitted by the server, and accordingly determines whether the existing firmware data of the FLASH ROM needs to be updated, and switches the path between the FPGA module and the FLASH ROM to the path between the CPU module and the FLASH ROM through the multiplexer when the existing firmware data of the FLASH ROM needs to be updated, and further updates the existing firmware data of the FLASH ROM to the new firmware data, so that the FPGA module can still operate normally without interference when the FLASH ROM performs firmware update.

Referring to fig. 1, fig. 1 is a system block diagram of an intelligent network card according to an embodiment of the present invention. As shown in fig. 1, an intelligent network card 100 includes a flash memory 1, a multiplexer 2, an FPGA module 3, and a CPU module 4. The smart card 100 is installed in a server host 200.
The flash memory 1 stores a conventional firmware data FW 1. The multiplexer 2 is electrically connected to the flash memory 1. The FPGA module 3 is electrically connected to the multiplexer 2, the multiplexer 2 is preset to communicatively connect the flash memory 1 and the FPGA module 3 in a preset operation mode, so that the FPGA module 3 loads the firmware data FW1 from the flash memory 1 through the multiplexer 2 in the preset operation mode, and sends a setting completion signal S1 after completing a firmware setting operation according to the firmware data FW 1. In addition, the FPGA module 3 further includes an FPGA processing unit 31 and a QSPI interface 32, wherein the FPGA processing unit 31 is electrically connected to the QSPI interface 32, and the QSPI interface 32 is electrically connected to the multiplexer 2, so that the FPGA processing unit 31 is electrically connected to the multiplexer 2 through the QSPI interface 32, and further loads the firmware data FW1 stored in the self-flash memory 1 through the multiplexer 2.
The CPU module 4 is electrically connected to the server host 200, the FPGA module 3, and the multiplexer 2, and configured to enter an update mode when receiving the setting completion signal S1 sent by the FPGA module 3 and a firmware update message S2 sent by the server host, and send a first switching signal S3 to the multiplexer 2 when the update mode is executed, so that the multiplexer 2 is switched to communicatively connect the flash memory 1 and the CPU module 4, and the firmware update message S2 is sent to the flash memory 1 through the multiplexer 2. In addition, the CPU module 4 further includes a CPU processing unit 41 and an SPI interface 42, the CPU processing unit 41 is electrically connected to the SPI interface 42, and the SPI interface 42 is electrically connected to the multiplexer 2, so that the CPU processing unit 41 is electrically connected to the multiplexer 2 through the SPI interface 42.
Referring to fig. 2, fig. 2 is a block diagram of a system for updating an intelligent network card through cooperation of a CPU module and a multiplexer according to an embodiment of the present invention. As shown in fig. 2, when the firmware data FW1 is updated to the new firmware data FW2, the CPU module 4 will send a second switching signal S3a to the multiplexer 2 to switch the multiplexer 2 back to communicatively connect the flash memory 1 and the FPGA module 3, so that the FPGA module 3 can retrieve the new firmware data FW2 from the flash memory 1 again, or load the new firmware data FW2 at the next boot.
Referring to fig. 1 to fig. 3, fig. 3 is a flowchart illustrating steps of a method for managing an update of an FPGA firmware of an intelligent network card according to an embodiment of the present invention. As shown in fig. 1 to fig. 3, taking the structure of the intelligent network card 100 as an example, the method for updating and managing the FPGA firmware of the intelligent network card of the present embodiment mainly includes the following steps: first, step S101 is to start the FPGA module 3, so that the FPGA module 3 loads the existing firmware data from the flash memory 1 through the multiplexer 2 to perform a firmware setting operation, and after the firmware setting operation is completed, step S102 is performed, and step S102 is performed, so that the FPGA module 3 sends a setting completion signal S1 to the CPU module 4.
After the FPGA module 3 in step S102 sends the setting completion signal S1 to the CPU module 4, step S103 is performed, and the CPU module 4 enters the update mode when receiving the setting completion signal S1 sent by the FPGA module 3 and the firmware update information S2 sent by the server host 200; when the CPU module 4 enters the refresh operation mode, step S104 is performed, and in step S104, the CPU module 4 sends a first switching signal S3 to the multiplexer 2, so that the multiplexer 2 switches to communicatively connect the flash memory 1 and the CPU module 4.

After the CPU module 4 in step S105 transmits the firmware update information S2 to the flash memory 1 via the multiplexer 2, in step S106, after the existing firmware data FW1 of the flash memory 1 is updated to the new firmware data FW2, the CPU module 4 transmits the second switching signal S3a to the multiplexer 2, so that the multiplexer 2 switches back to communicatively connect the flash memory 1 and the FPGA module 3.
As mentioned above, after the CPU module 4 switches the multiplexer 2 back to the communication connection between the flash memory 1 and the FPGA module 3, since the flash memory 1 is updated with the new firmware data FW2, the FPGA module 3 can load the new firmware data FW2 from the flash memory 1 again to perform a firmware resetting operation, and the FPGA processing unit 31 of the FPGA module 3 sends a resetting completion signal S1a to the CPU module 4 after the firmware resetting operation is completed, and the CPU module 4 sends a restarting signal (not shown) to the server host 200 after receiving the resetting completion signal S1a, so that the server host 200 restarts the power supply of the smart network card 100.
In summary, compared with the existing intelligent network card, because the BMC is not provided, firmware update can only be performed on the FLASH ROM through the FPGA, and thus the FPGA cannot normally operate when the firmware is updated; when the existing firmware data of the FLASH ROM needs to be updated, the CPU module is used for controlling the multiplexer to switch the path between the FPGA module and the FLASH ROM into the path between the CPU module and the FLASH ROM, and then the existing firmware data of the FLASH ROM is updated into new firmware data, so that the FPGA module can still normally operate without interference when the FLASH ROM is used for updating the firmware.
