How to use the Intel RealSense D435i with the Jetson Orin Nano?

As the title says how do I connect the D435i with the Jetson Orin Nano? I tried the steps on this page: Isaac ROS RealSense
But I got the following error: bash: cd: /src: No such file or directory

Hi @anay.gokhale123

Thanks for your post.

But I got the following error: bash: cd: /src: No such file or directory

It might caused by the missing step to “Create a ROS 2 workspace for experimenting with Isaac ROS” in step4.
Could you please help to check if it helps? Thanks.

Hello,

Do I have to connect my Jetson Orin Nano to an ssd for this to work? or can I try with sd card and change if I think it is too slow?
Thanks

Hi @anay.gokhale123

To use SD-card/USB-drive are not recommended, becuase the speed is too slow.
Here’s the table to show the read/write speed between each storages:

Please refer to the below link:

To use SSD connected over NVMe (PCIe) interface for better performance, thanks

@jolin is there a method that does not require ssd? It is a very basic requirement to use the realsense camera with jetson orin nano. I feel like there should be a simple method that I am missing

Hi @anay.gokhale123

This leads to your previous question:

or can I try with sd card and change if I think it is too slow?

Yes, you still can try the method without SSD.
And change to use SSD if the performance is too slow to be acceptable.

Please refer to the previous doc to modify the steps and export ISAAC_ROS_WS with the corresponding path, thanks:
e.g.

 << x86_64 and Jetson without SSD >>
mkdir -p  ~/workspaces/isaac_ros-dev/src
echo "export ISAAC_ROS_WS=${HOME}/workspaces/isaac_ros-dev/" >> ~/.bashrc
source ~/.bashrc

Hello,
Thank you for your reply. My last question was more looking for if there is another method besides the one you originally posted that would work for an sd card? Either way thank you again for your help, I will try the provided method tonight using my sd card
