Abstract
A server includes a motherboard and a programmable logic device coupled to the motherboard. The server also includes a hardware device coupled to the motherboard and the programmable logic device. The server further includes a non-volatile memory storing firmware for the hardware device. The non-volatile memory is coupled to the motherboard and the programmable logic device. The server further includes a peripheral device coupled to the motherboard and the programmable logic device. The peripheral device receives firmware data from a management server. The peripheral device verifies that the firmware data corresponds to the hardware device. The peripheral device further holds the hardware device in reset mode. The peripheral device stores the firmware data on the non-volatile memory to update the firmware and releases the hardware device from reset mode after updating the firmware.
