description	Knowledge base for the relationship between JetPack and Jetson — JetPack components (L4T + SDK), Ubuntu version mapping, supported Seeed products, Super Mode, and JetPack archive links.

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: https://docs.google.com/spreadsheets/d/1Sf7IdmVkKTAUH95XwxHK0ojV5aFq3ItKZ-iT28egzIk/edit?pli=1&gid=0#gid=0

---

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
