Nvidia Xavier NX User Guide

Setting up the system

Required hardware

  • 9V to 19V power supply for Jetson.
  • 5V power supply for the interposer.
  • To run the system in standalone mode, besides the accessories that are provided in the AD-FXTOF1-EBZ box you'll need an additional HDMI cable to connect to a monitor and a USB keyboard and mouse
  • Camera flex cable for connection between Xavier NX and AD-FXTOF1-EBZ

Prepare SD card

  • Follow steps presented on Nvidia Website for creating Xavier NX SD card
  • Download L4T BSP L4T BSP package (Tested release R32.3.1)
  • Extract kernel_src from BSP package
  • ADI ToF camera driver and devicetree should be taken from aditof_sdk.
  • Copy paste and replace content of kernel_src folder from L4T BSP with the one downloaded from ADI ToF Repository
  • Build Kernel and devicetree blob following instructions from Building_the_Kernel_from_Source selecting “CONFIG_VIDEO_ADDI9036” and “CONFIG_EEPROM_AT24” using menuconfig
  • Copy generated kernel Image and devicetree to SD card

Power on sequence

  • Plug the SD card into the Nvidia Xavier NX SD card slot
  • Connect the HDMI cable from the monitor to the Jetson HDMI connector
  • Connect the molex cable between the camera and the interposer
  • Connect the camera cable between the J1 connector of Jetson Xavier NX and the P1 connector of the interposer
  • Connect a USB mouse and keyboard to the Xavier NX
  • Connect the power supply to the interposer
  • connect the 9V-19V power supply to the Xavier NX. Once power is connected to the Jetson the system will boot the Linux OS from the SD card.

Power off sequence

  • Open a terminal and type sudo poweroff. This will safely power off and ensure that the SD card is properly unmounted
  • remove the 9-19V supply from the Nvidia Jetson
  • remove the 5V supply from the interposer

Troubleshooting

  • Linux does not boot
    • The SD card is corrupted and this prevents the system from booting. Reflash the SD card or check generated devicetree or kernel image

Running the evaluation application

This example demonstrates how to capture data from the TOF system on the Nvidia Xavier NX and display it using OpenCV.
