Abstract: Examples described herein relate to a circuit board that includes a device, firmware memory, and a power controller. In some examples, the firmware memory is to store a firmware update and in response to a software-initiated command, the power controller is to reduce power to the device to cause a firmware update of the device and restore power to the device to cause execution of the firmware update. In some examples, the power controller is to reduce power solely to the device independent from power supply to at least one other device. In some examples, device configuration is saved prior to reduction of power to the device and restored to the device after power is restored to the device.
