Setting up the system
Required hardware
- 5V power supply for Jetson. (Jetson board can be powered up from USB but external 4A 5V supply is recommended)
- To run the system in standalone mode, besides the accessories that are provided in the AD-96TOF1-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 Jetson and AD-96TOF1-EBZ
Modifying the AD-96TOF1-EBZ to work with the Nvidia Jetson Nano
All changes required for RPi are applicable to Nvidia Jetson. So please follow the instructions presented here: Raspberry Pi User Guide
Prepare SD card
- Follow steps presented on Nvidia Website for creating Jetson Nano 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 Jetson SD card slot
- Connect the HDMI cable from the monitor to the Jetson HDMI connector
- Connect the camera cable between the Jetson Nano and the P1 connector of the ToF board
- Connect a USB mouse and keyboard to the Jetson
- connect the 5V power supply to the camera board and set the camera power switch S2 to on. Once the camera board is powered up the DS1 LED will turn on
- connect the 5V power supply to the Jetson Nano. Once power is connected to the Jetson the system will boot the Linux OS from the SD card.
Password for “analog” user is “analog”. This user has sudo rights
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 5V supply from the Nvidia Jetson
- Set the camera board power switch to off
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 jetson and display it using OpenCV. Due to limitations in the Nvidia Jetson software infrastructure for MIPI virtual channels support, only one video stream is available at a time, depth or IR.
