The invention relates to the technical field of
firmware upgrading, and discloses a board-level
system firmware upgrading
system, method and device, a medium and a product, the board-level
system firmware upgrading system comprises a substrate management controller and a board-level system, the substrate management controller uses an
intelligent platform management interface to send a plurality of firmware upgrading data packets to the board-level system, the
data format of the firmware upgrading data packet comprises a firmware information segment, and the segment is used for recording a firmware upgrading information fragment and is obtained by expanding a
data segment in the protocol message; and the board-level system receives and splices the firmware upgrading information fragments in the firmware upgrading data packets to obtain firmware upgrading information, and the firmware is upgraded according to the firmware upgrading information. According to the invention, the firmware
upgrade package is split and written into the plurality of firmware
upgrade packages, the firmware
upgrade packages are sent through the
intelligent platform management interface, and the board-level system integrates the plurality of firmware upgrade fragments to obtain the complete firmware upgrade
package for upgrading, so that the problem of inconvenience in firmware upgrade by using a
serial port is solved.
