Abstract
Provided are a method and system for upgrading firmware. The method includes: an upgrading control single board receives a firmware upgrading request from a master control single board, wherein the firmware upgrading request carries firmware upgrading parameter information; the upgrading control single board determines, according to the firmware upgrading parameter information, a sublink to be upgraded corresponding to the firmware upgrading parameter information; and the upgrading control single board acquires, from the master control single board, firmware upgrading data corresponding to the sublink to be upgraded, and upgrades, by adopting the firmware upgrading data, one or more pieces of firmware on the sublink to be upgraded. According to the solution, under a power-on state of a bare single board to be upgraded, remote firmware upgrading can be performed for the single board, so that the risk of influence of firmware upgrading operation on normal running of the system is lowered.
