Abstract: An autonomous driving system having dual secure boot is provided. The autonomous driving system includes: a control system, a host, and a baseboard management controller (BMC). The control system includes a microcontroller, a first flash memory, and a second flash memory. The first flash memory stores first embedded-controller firmware and a first application image file. The second flash memory stores second embedded-controller firmware and a second application image file. When the autonomous driving system is turned on, the microcontroller executes a dual secure boot procedure to execute the first embedded-controller firmware or the second embedded-controller firmware. In response to the microcontroller successfully executing the first embedded-controller firmware or the second embedded-controller firmware, the microcontroller authenticates the first application image file or the second application image file.

Abstract: A power supply protection method for a power supply device includes: detecting whether an output voltage of the power supply device reaches a voltage protection threshold to generate a detection result; generating a first control signal according to a power good input signal and the detection result; utilizing a fault protection circuit to decide whether to output a fault protection signal according to the first control signal; and using a short circuit protection circuit to receive the power good input signal and determining whether to generate a second control signal according to the power good input signal. When the power good input signal is not enabled during a specific time after the power supply device is started, the short circuit protection circuit is directly used to generate the second control signal into the fault protection circuit for triggering the fault protection circuit to output the fault protection signal.
