The present disclosure relates to a method for updating a firmware component of a measurement and control technology device. The method includes: a segment-by-segment reception of a first firmware image; an authentication of the first firmware image based upon a first encryption method; a creation of a second authentication datum for the first firmware image via an algorithm that differs from the first encryption method; a re-transmission of the data used for updating the firmware component as a second firmware image; an authentication of the second-firmware image based upon the second authentication datum; and in the case of a successful authentication of the second firmware image, enabling and execution of the firmware program code.

The embodiment of the invention discloses an establishing method and system of a trust chain. The method comprises the steps of starting a BMC module and a TCM module before a server is powered on; adopting the TCM module to scale BMC firmware in the BMC module to obtain a first scaling result, and judging whether or not the BMC firmware is tampered according to the first scaling result; if the BMC firmware is not tampered, adopting the BMC firmware to scale BIOS-Boot-Block to obtain a second scaling result, and judging whether or not the BIOS-Boot-Block is tampered according to the second scaling result; if the BIOS-Boot-Block is not tampered, controlling a power control module to power on the server, and adopting a BIOS to establish the subsequent trust chain. According to the establishing method and system of the trust chain, the safety of the trust chain is improved when the trust chain is established, and accordingly the safety of the system is improved.

A system and method for performing sleep state enhancements in a computing device using firmware and NVDIMMs that include DRAM and flash memory is discussed. The flash-backed DRAM covers all of platform memory. All writes to DRAM during system operation are propagated to the flash. Sleep state requests trigger a System Management Interrupt and a firmware a SMI handler handles the sleep state request so as to enable power savings during the sleep state and facilitate faster resume times when exiting the sleep state.

The invention discloses a method for restoring a damaged firmware module in an A working area of Hitachi hardware. The method is characterized in that when the firmware module in the A working area of the Hitachi hardware is damaged and cannot be recognized by a computer, the working area of the hard disk is converted to obtain the necessary firmware module, and the necessary firmware module is written in the A working area according to an offset address and an offset, so that the hard disk can be recognized by the computer, and thus the faulty hard disk is effectively restored, and the problems that manpower and material resources are consumed by direct detachment, head replacement and other methods, the problems of expanded fault of the hard disk, secondary damage to the hard disk and even complete damage of the hard disk and the like caused by artificial factors in detachment, replacement and other operations are solved.

A communication method provided by the invention is a point-to-point communication method having a low data transfer rate, and transmits information, commands and configurations of electronic equipment provided with a light receiver by modulating light emitted by a flashlight of a handheld device having processing capabilities. The launch operation is handled by an application installed in a handheld device, such as a smartphone, tablet, or the like. The receiving operation is processed by the electronic equipment to be configured. The transmitting equipment exists in a handheld device, and the handheld device is provided with an application program and a flash lamp. The receiving device is installed in an electronic device to be configured. And the electronic equipment consists of a powersupply (A), a luminosity sensor (B) for monitoring the change of luminosity emitted by the flashlight (F) of the handheld device regardless of the environment, an analog-to-digital converter (C) forconverting an analog signal from the luminosity sensor into a digital signal, a microcontroller (D) for receiving firmware and processing the digital signal, and an electronic equipment or load control device (E) to be adjusted.

The invention discloses a device for flashing BMC Flash, and the device comprises a controller which is used for being in communication connection with a configuration server, and obtaining Flash firmware corresponding to a code from the configuration server according to the preset code; when a trigger signal sent by the input device is received, the obtained Flash firmware is flashed into Flash of a BMC connected with the controller; and the input device is connected with the controller. By applying the technical scheme provided by the embodiment of the invention, the risk of flashing errorsis reduced, the flashing efficiency is favorably improved, and the invention further provides a method for flashing the BMC Flash, which has corresponding technical effects.
