Please help to guide me on how to hard reboot the host system? AFAIK, using the command line “sudo reboot” or “reboot” only reboots the guest system, is it correct?

Dear @v.tripc2,
Could you see poweroff/on in aurix helps?(DRIVE OS Linux)

Thanks @SivaRamaKrishnaNV , I could reboot the device successfully using poweroff/on commands in AURIX via minicom with USB UART connection.
BTW, are there other ways to execute AURIX commands from the console session of Guest OS (Linux, QNX) of NVIDIA Drive?
