Abstract: A method and an apparatus for accessing physical resources, is used to restrict access to physical resources of other light system kernel Light OSs by a first Light OS in a multi-kernel operating system and ensure security of accessing physical resources among the Light OSs. A method, executed by secure firmware, includes: receiving a physical address corresponding to a physical resource to be accessed by the first Light OS; determining whether the physical address corresponding to the physical resource is out of bounds; and if the physical address corresponding to the physical resource is within bounds, sending an access continuity signal to the first Light OS; or if the physical address corresponding to the physical resource is out of bounds, sending an access error signal to the first Light OS.
