Log from jtop 4.2.9

[dsconnol-impactai]

Hey! Just some added info. I had the same issue on a new AGX Orin. It went away after running nvpmodel -m 0 for unrelated reasons. My guess is that the nvpmodel mode isn't set, so it can't get looked up.

[SijmenHuizenga]

Hi, thanks for the comment @dsconnol-impactai. We also had a misconfigured power mode (sudo nvpmodel -q --verbose gave error). After fixing that, jtop works great.
