In this embodiment, the memory 116 is a flash memory having a serial peripheral interface, and the processing unit 112 and the memory control module 60 also have a serial peripheral interface, so that the selector 50 can selectively connect the serial peripheral interface of the memory 116 with the serial peripheral interface of the processing unit 112 or the serial peripheral interface of the memory control module 60. In another embodiment, the memory 116 is an electrically erasable programmable read-only memory having an integrated circuit bus interface, and the processing unit 112 and the memory control module 60 also have an integrated circuit bus interface, such that the selector 50 can selectively connect the integrated circuit bus interface of the memory 116 with the integrated circuit bus interface of the processing unit 112 or the integrated circuit bus interface of the memory control module 60.
When the add-in card 110 is inserted into a slot of the motherboard 122, the motherboard 122 of the electronic device 120 establishes a connection with the add-in card 110 through the bus interface 70 (i.e., the bus interface 70 is configured to establish a connection with the add-in card 110); the control unit 80 is configured to set the memory control module 60 such that the selector 50 selects to connect the memory 116 to the memory control module 60; then, accessing the memory control module 60 to burn the new firmware into the memory 116 through the memory control module 60; the memory control module 60 is then arranged to cause the selector 50 to select the connection of the memory 116 to the processing unit 112; memory control module 60 is then set up to trigger processing unit 112 to reload the new firmware in memory 116.
Specifically, the electronic device 120 reads the new firmware from the network or the hard disk via the motherboard 122 (i.e., acquires the new firmware) based on the firmware maintenance requirements of the add-in card 110; next, the control unit 80 of the motherboard 122 sets the memory control module 60 through the bus interface 70, so that the selector 50 selects to connect the serial peripheral interface of the memory 116 to the serial peripheral interface of the memory control module 60; then, the control unit 80 of the motherboard 122 accesses the memory control module 60 through the bus interface 70 to transmit the new firmware to the memory control module 60, so that the new firmware is burned into the memory 116 through the memory control module 60; then, the control unit 80 of the motherboard 122 sets the memory control module 60 through the bus interface 70, so that the selector 50 selects to switch the serial peripheral interface of the memory 116 to the serial peripheral interface of the processing unit 112; finally, the control unit 80 of the motherboard 122 sets the memory control module 60 via the bus interface 70, so that the memory control module 60 triggers the processing unit 112 to reload the new firmware in the memory 116.

Specifically, the memory controller 64 is configured to send write commands to the memory 116 through the command register 66; and sends the data of the new firmware to memory 116 through data register 68.

Thus, firmware maintenance system 100 can aid in fault location for a failed add-in card 110 that returns during production or during operation.

In particular, the memory controller 64 is configured to send read commands to the memory 116 through the command register 66; and the data of the current firmware stored by memory 116 is read back to memory 116 through data register 68.
In an embodiment, the control unit 80 is further configured to, when determining that the current firmware stored in the memory 116 is damaged, access the memory control module 60 to burn, into the memory 116, lossless firmware corresponding to the current firmware through the memory control module 60. Thus, if add-in card 110 fails due to firmware corruption, firmware maintenance system 100 can facilitate easy repair without the use of additional tools such as a burner.
In one embodiment, the bus interface 70 is a system management bus interface, the logic device 114 is a complex programmable logic device, and the logic device 114 may further include: the memory control module 60 may include a system management bus controller 90 connected to a system management bus interface (i.e., the bus interface 70): memory controller 64, command register 66, and data register 68; the control unit 80 is configured to read and write the command register 66 and the data register 68 through the system management bus controller 90, so that the memory controller 64 accesses the memory 116 through the command register 66 and the data register 68, and burns the complete and correct current firmware (i.e., the lossless firmware corresponding to the current firmware) into the memory 116.

a control unit connected to the bus interface and configured to set the memory control module so that the selector selects the memory to be connected to the memory control module; then, accessing the memory control module to burn new firmware into the memory through the memory control module; then, setting the memory control module to cause the selector to select to connect the memory to the processing unit; thereafter, the memory control module is configured to trigger the processing unit to reload the new firmware in the memory.
9. The firmware maintenance system of claim 8, wherein the bus interface is a system management bus interface, the plug-in card is a peripheral component interconnect express (PCI express) plug-in card, the system management bus interface further configured to establish a connection with the PCI express plug-in card that is not functioning properly; the control unit is further configured to set the memory control module of the peripheral component interconnect express card that is not normally operable to cause the selector to select the memory to be connected to the memory control module; then, accessing the memory control module to read back the current firmware stored by the memory through the memory control module and store the current firmware in a file form on an external memory; then, it is determined whether the current firmware stored by the memory is corrupted based on the read back file stored by the external memory.
10. The firmware maintenance system of claim 9, wherein the control unit is further configured to access the memory control module to burn, by the memory control module, the lossless firmware corresponding to the current firmware into the memory when determining that the current firmware stored in the memory is corrupted.
11. A firmware maintenance system as in claim 9, wherein the memory is a flash memory or an eeprom, the memory control module comprises a memory controller that is a serial peripheral interface controller or an ic bus controller, and the external memory is a disk or a solid state disk of a server or a personal computer.
12. The firmware maintenance system of claim 8, wherein the memory control module includes a control register, the control unit configured to set the control register to control selection of the selector or to trigger a restart signal or a reload signal to the processing unit.
13. The firmware maintenance system of claim 8, wherein the bus interface is a system management bus interface, the logic device is a complex programmable logic device, the logic device further comprising: a system management bus controller connected to the system management bus interface, the memory control module comprising: a memory controller, a command register and a data register; the control unit is configured to read and write the command register and the data register through the system management bus controller, so that the memory controller accesses the memory through the command register and the data register and burns the new firmware into the memory.
14. The firmware maintenance system of claim 13, wherein the memory controller is configured to send a write command to the memory through the command register; and sending data of the new firmware to the memory through the data register.
15. A firmware maintenance system as claimed in claim 8, wherein the processing unit is a processor or a field programmable logic array; the control unit is configured to set the memory control module to restart the processor or trigger the field programmable logic array to reload the new firmware in the memory.
16. A firmware maintenance system as claimed in claim 8, wherein the selector connects the memory to the processing unit by default.
