Abstract: A computing device comprises a primary printed circuit board (PCB), one or more computing components mounted to the primary PCB, a baseboard management controller (BMC) mounted to the primary PCB, a power subsystem, and a logic device coupled to the primary PCB. The power subsystem comprises a power controller with a first logic pin, and the logic device is communicably connected to the first logic pin. The logic device is configured to program the power controller by placing the power controller in a programming mode and inputting programming information into the power controller via the first logic pin.

Abstract: A power supply unit (PSU) comprises power conversion circuitry to convert input power into output power for an electronic system, microcontrollers to control operations of the power conversion circuitry, and a secure element communicably connected to a first microcontroller. The secure element and the microcontrollers are all paired together with each storing shared pairing information. The secure element and the microcontrollers comprise security logic. The security logic may be configured to, in response to a power on sequence being initiated, validate the secure element and the microcontrollers based on the shared pairing information, and make completion of the power on sequence conditional on successful validation. The security logic may be configured to, in response to receiving a new firmware image for updating one of the microcontrollers, use the secure element to validate the new firmware image and make acceptance of the new firmware image conditional on successful validation.
