The PCI express switch 22 comprises a switch-side UART 221, a switch-side storage module 222, and a switch-side processing module 223 electrically connected to the switch-side UART 221 and the switch-side storage module 222.
In this embodiment, the host 1 can be implemented as a personal computer, a server, or a cloud host, but not limited thereto.
In this embodiment, the implementation of the substrate Management unit 21 is, for example, a Baseboard Management Controller, BMC for short.
In this embodiment, the Peripheral Component Interconnect Express Switch 22 is implemented by, for example, a Peripheral Component Interconnect Express Switch, PCIe Switch for short, but not limited thereto.
In this embodiment, the implementation of the substrate-side UART interface 212 and the switch-side UART interface 221 is, for example, Universal Asynchronous Receiver/Transmitter, UART for short, and can communicate through an Asynchronous file transfer Protocol, for example, Xmodem Protocol, but not limited thereto.
Referring to fig. 3, the following describes the operation details of the baseboard management unit 21 included in the computer host 1 and the firmware update system 2 and the components of the pci express switch 22 according to the embodiment of the present invention, wherein the firmware update method of the pci express switch includes a step 51, a step 52, a step 53, and a step 54.
In step 51, the host computer 1 transmits the firmware update file stored in the host-side storage module 12 and associated with the pci express switch to the bmu 21.
In step 52, the baseboard management unit 21 stores the firmware update file into the baseboard storage module 213 after receiving the firmware update file from the host computer 1, and transmits the firmware update file to the PCI express switch 22 via the asynchronous file transfer protocol. It should be noted that, in this embodiment, the baseboard management unit 21 detects whether the corresponding management network communication PORT (PORT) in the baseboard management unit 21 receives the update request from the host computer 1 through the Restful Api Service, and generates and transmits an information request related to the firmware update file to the host computer 1 after detecting that the corresponding management network communication PORT receives the update request, so that the host computer 1 transmits the stored firmware update file to the baseboard management unit 21 after receiving the information request.
Referring to FIG. 4, it should be particularly noted that the process of transferring the firmware update file to the PCI express switch 22 further comprises a sub-step 521, a sub-step 522, and a sub-step 523.
In the sub-step 521, the baseboard management unit 21 generates and transmits a firmware update file transmission request to the PCI express switch 22 after receiving the firmware update file.
In sub-step 522, the PCI express switch 22 initiates the asynchronous file transfer protocol after receiving the firmware update file transmission request, and waits for the firmware update file transmitted by the baseboard management unit 21.
In the sub-step 523, the baseboard management unit 21 transmits the firmware update file to the PCI express switch 22 via the asynchronous file transfer protocol.
In step 53, the PCI express switch 22 updates the firmware update file according to the firmware update file received from the baseboard management unit 21.
Referring to fig. 5, it should be particularly noted that the process of updating according to the firmware update file further includes a sub-step 531, a sub-step 532, a sub-step 533, a sub-step 534, a sub-step 535, and a sub-step 536.
In the sub-step 531, the PCI express switch 22 determines whether the firmware update file is damaged during the transmission process after receiving the firmware update file from the host computer 1 via the asynchronous file transfer protocol. When the PCI express switch 22 determines that the firmware update file is not damaged during the transmission process, the process proceeds to substep 532; when the PCI express switch 22 determines that the firmware update file is damaged during transmission, the process proceeds to substep 535. Specifically, in the embodiment, the PCI express switch 22 determines whether the firmware update file is damaged during transmission by using Cyclic Redundancy Check (CRC) and/or Checksum (Checksum).
In the sub-step 532, the pci express switch 22 stores the firmware update file in the switch storage module 222, and then generates a successful receipt reply, and transmits the successful receipt reply to the bmu 21 via the atm protocol.
In sub-step 533, the bmc 21 generates an update command associated with the firmware update file after receiving the successful receipt reply via the atm protocol, and transmits the update command to the pci express switch 22 via the atm protocol.
In the sub-step 534, the pci express switch 22 updates the firmware update file stored in the switch storage module 222 in the sub-step 534 after receiving the update command from the bmu 21 via the atm protocol.
In sub-step 535, the PCI express switch 22 generates a reception failure reply and sends the reception failure reply to the baseboard management unit 21 via the asynchronous file transfer protocol.
In sub-step 536, the baseboard management unit 21 returns to step 52 after receiving the reception failure reply via the asynchronous file transfer protocol.
In step 54, the PCI express switch 22 restarts and executes the firmware update after completing the update of the firmware update.
To sum up, the firmware update method of the pci express switch according to the present invention is that the computer host 1 remotely transmits the firmware update file to the bmu 21 through the wireless network 200, then the bmu 21 transmits the firmware update file to the pci express switch 22 through the atm protocol, and then the pci express switch 22 determines the integrity and correctness of the firmware update file by using the crc and/or checksum method, and then updates the firmware according to the firmware update file and restarts the firmware update file, so that the firmware update of the pci express switch 22 can be easily completed through remote operation without field wiring. Therefore, the object of the present invention can be achieved.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
