"nvidia-smi" not working. Nvidia-Xavier Soc(ZF-ProAI)

Hello everyone,

I am working on a device called ZF-ProAI which is composed of a safety microcontroller (Aurix) and a performance microprocessor (Nvidia Xavier SoC). The Nvidia Xavier SoC includes an ARM-based octacore CPU and a Volta GPU.

Technical specification of ZF-ProAI includes Nvidia-Xavier-SOC, CPU 8 Cores @ 2.1 GHz, GPU Volta, 4TPC with Linux tegra-ubuntu 4.14.78-rt44-tegra OS installed in it. This hardware is sold with this preinstalled OS and with CUDA-10 .1 for AI development.

nvidia@tegra-ubuntu:~$ nvidia-smi

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

I am unable to find the exact driver installed. Can anyone help me with this issue.

Thank you in advance.
