Hi, what version of ROS 2 did you install and how did you do that?

[raysu1027]

Hi alsora, It's ROS 2 Galactic. I am follw this link. https://iroboteducation.github.io/create3_docs/setup/ubuntu2004/

[alsora]

Those instructions are for a desktop (x86_64) build of ROS 2. I think you are running on a Jetson Xavier, so those instruction are likely not correct.

Hi alsora, But create3 documentation can use on jenson. like this https://iroboteducation.github.io/create3_docs/setup/jetson/ Am i missing something?

[alsora]

Yes, but note that these instructions are different from those you linked before. Did you follow the jetson specific instructions ?

And FYI, this problem is not rekated to Create 3 software, but rather "how to setup ROS 2 on NVidia jetson".

Also, to chime in here: Jetson support is via the community, and this is issue is not with Create 3 examples; I am moving this to a discussion, and we can continue it there with the community.
