Abstract
One or more ECU's in an automotive vehicle have a contingent boot and an authenticated boot. When each such ECU is initialized, that ECU performs the contingent boot and the authenticated boot in parallel. The authenticated boot authenticates operational firmware for that ECU that is stored in flash memory of that ECU, starting with initial firmware of the operational firmware. Contingent boot firmware is stored in flash memory of the ECU or is stored in essentially non-alterable memory of the ECU. The contingent boot executes the ECU contingent boot firmware for that ECU. The contingent boot firmware has limited functionality and does not have the ability to flash the flash memory. Upon successful authentication of the initial firmware, the ECU executes the initial firmware and terminates the contingent boot.
