Note this is similar to this issue: An error occurs about GPU device count when I try to run the sample
But there was no resolution on this topic.
Hi, we were able to generate the sample cross compilation files following the “Samples Cross-Compilation From Source” section from this link DriveWorks SDK Reference: Getting Started Using the NVIDIA SDK Manager.
We moved the resulting bin files over to the Orin device and were able to run the sample_hello_world file.
However, we are now getting an error when running sample_hello_world:

Rebooting did not help resolve this issue, our only way to resolve this was to re-flash the Orin device. This worked after reflashing, but the error came back. Do you know what this issue could be? We are also trying to get the sample_camera running as well and are running into errors as well. Thank you.
