  • Backup storage of vital debug information
    Patent number: 9857998
    Abstract: A system includes non-volatile memory storing firmware and an embedded baseboard management controller (BMC). The BMC includes a BMC volatile memory and a BMC processor coupled to the BMC volatile memory and the non-volatile memory. The BMC processor performs a first method wherein the firmware is obtained from the non-volatile memory, instrumented, and stored on a host computer volatile memory. Also in the first method, separate copies of vital debug information about the instrumented firmware are stored on the BMC volatile memory and the host computer volatile memory. The system further includes a host computer housing the embedded BMC, the host computer volatile memory, and a host computer processor coupled to the host computer volatile memory. The host computer processor performs a second method wherein the instrumented firmware is obtained from the host computer volatile memory and executed.
