Isaac ROS Nova on Jetson Orin NX - failed to open the device /dev/nvpps0 errno = 2

[winton.hsu]

• Device: Jetson Orin NX
• JetPack Version: JetPack 6.1
• Isaac ROS Version: 3.2

Issue Description

I am running Isaac ROS Nova on my Jetson Orin NX, but I encountered the following error:
ERROR extensions/timestamp_correlator/correlated_timestamp_driver.cpp@74: failed to open the device /dev/nvpps0 errno = 2

• I checked using ls /dev, but /dev/nvpps0 is missing.
  

  

• Searched kernel logs using dmesg | grep nvpps
  

  

Questions

• Does Isaac ROS Nova require /dev/nvpps0, and which module or driver is responsible for it?
• How can I enable or ensure that /dev/nvpps0 is properly created?
• Do I need to manually load specific kernel modules for Isaac ROS Nova?
