Overview of JetPack and Jetson
This is a knowledge-base skill. Use it to answer questions about JetPack
composition, version mappings, and Seeed product compatibility.
Execution model
This skill is informational — no destructive commands. Present relevant
sections to the user based on their question.
Phase 1 — identify the user's question
Determine which topic the user needs:
- What JetPack is composed of → Section A
- JetPack ↔ Ubuntu version mapping → Section B
- Which JetPack versions Seeed products support → Section C
- JetPack 6.2 and Super Mode → Section D
- How to find contents of each JetPack version → Section E
[OK] when topic is identified.
Section A — JetPack composition
JetPack has two major components:
① L4T (Linux for Tegra) — middleware Linux distribution for Jetson:
- Ubuntu root filesystem
- Linux kernel (with NVIDIA patches)
- Drivers (GPU, ISP, CSI, I2C, etc.)
- Firmware (Bootloader, UEFI, U-Boot, initrd)
- BSP (Board Support Package) — device trees, boot configs, flash tools
② JetPack SDK — upper software layer for application development:
- CUDA Toolkit
- cuDNN (Deep Learning Library)
- TensorRT (AI Model Inference Engine)
Section B — JetPack / L4T / Ubuntu version mapping
| JetPack | L4T | Ubuntu |
|---|
| 6.2 | 36.4.3 | 22.04 |
| 6.1 | 36.4.0 | 22.04 |
| 6.0 | 36.3.0 | 22.04 |
| 5.1.3 | 35.5.0 | 20.04 |
| 5.1.1 | 35.3.1 | 20.04 |
| 4.6.6 | 32.7.6 | 18.04 |
Check current version on device:
cat /etc/nv_tegra_release
Section C — Seeed product JetPack support
Full compatibility matrix:

Section D — JetPack 6.2 and Super Mode
Devices flashed with JetPack 6.2 support Super Mode activation.
Super Mode is currently available only on select Seeed products.
Section E — JetPack version archive
Official NVIDIA JetPack archive with contents of each release:
https://developer.nvidia.com/embedded/jetpack-archive
Failure decision tree
| Symptom | Action |
|---|
| User unsure which JetPack version they have | Run cat /etc/nv_tegra_release on the Jetson device |
| L4T version doesn't match any known JetPack | Check NVIDIA archive: https://developer.nvidia.com/embedded/jetpack-archive |
| Seeed product not in compatibility matrix | Contact Seeed support or check the Seeed wiki for latest updates |
