You actually have JetPack installed — the reason jtop shows “JetPack: MISSING” is because it detects JetPack based on the L4T version, not on the JetPack packages.

jtop reads the file /etc/nv_tegra_release to determine which JetPack release the system was flashed with.
If that file is missing or doesn’t match your system, jtop can’t identify the JetPack version and displays MISSING even though CUDA, cuDNN, and TensorRT are present.

You can confirm your real JetPack version by checking the L4T release:

cat /etc/nv_tegra_release

or:

cat /etc/os-release

Then match the L4T version with NVIDIA’s JetPack/L4T table. For example:

  • L4T 36.4.x → JetPack 6.2.1

So even if jtop says “MISSING,” your JetPack version is whatever corresponds to your L4T version.

If you want jtop to recognize it properly, make sure /etc/nv_tegra_release exists and contains the correct L4T/JetPack information.strong text
