Abstract:
There is provided a device (100) having hardware (102) and a first, upgradable, firmware (106) for controlling the hardware. The device further has a hypervisor (104) which links the first firmware to the hardware so as to control access of the first firmware to the hardware. In preparation for an upgrade of the first firmware, the hypervisor is configured to deny access of the first firmware to the hardware, access a second firmware, and control the hardware by the second firmware.
