What is l4t-differences?

A comparison guide for Seeed and NVIDIA versions of the Linux software package that supports Jetson hardware. It lists hardware-specific driver changes across several software versions.

Checking L4T and JetPack versions, comparing CAN bus, Wi-Fi, Ethernet, GMSL, TPM, audio, and USB support, and troubleshooting Seeed Jetson devices.

It helps explain why a Seeed Jetson board may behave differently from standard NVIDIA documentation and which drivers are included in each version.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00084	$0.01431
Opus 5	$0.00042	$0.00715
Sonnet 5	$0.00017	$0.00286
Haiku 4.5	$0.00008	$0.00143

Security

Grade B, and why

l4t-differences scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

Differences in L4T between Seeed and NVIDIA

Seeed's Jetson BSPs are based on NVIDIA's L4T with modifications to support Seeed hardware. This skill identifies the specific driver and feature differences per L4T version so users can understand what Seeed adds on top of the NVIDIA baseline.

Execution model

Run one phase at a time. After each phase:

Relay all output to the user.
If output contains [STOP] → stop, consult the failure decision tree.
If output ends with [OK] → tell the user "Phase N complete" and proceed.

Prerequisites

Requirement	Detail
Hardware	Seeed Jetson device (reComputer series)
JetPack	Identify installed version before proceeding

Phase 1 — Identify L4T version (~30 s)

cat /etc/nv_tegra_release

Or:

dpkg -l | grep -i nvidia-l4t-core

[OK] when L4T version string is displayed (e.g. R36.4.3, R35.5). [STOP] if file not found — device may not be running L4T.

Phase 2 — Identify JetPack version (~30 s)

dpkg -l | grep -i jetpack

Map the L4T version to JetPack:

L4T Version	JetPack
36.4.3	6.2
36.4	6.1
36.3	6.0
35.5	5.1.3
35.3.1	5.1.1

[OK] when JetPack version is confirmed.

Phase 3 — Review Seeed BSP differences for your version

Based on the L4T version identified in Phase 1, here are the key additions Seeed makes over NVIDIA's default BSP:

L4T 36.4.3 (JetPack 6.2)

MCP251X / MCP251XFD CAN bus controllers
Intel Wi-Fi driver (generic + modular + tracing)
Microchip LAN743x Gigabit Ethernet
PPP protocol support (async serial)
Realtek 88-series Wi-Fi (8723D, 8723DU, 8723X, USB)
TI TLV320AIC3X audio codec (I²C)
MAX9296A / MAX96717 / MAX96724 GMSL deserializers + aggregator
CRC-CCITT checksum, advanced video debug interface

L4T 36.4 (JetPack 6.1)

MCP251X / MCP251XFD CAN bus controllers
Intel Wi-Fi MVM driver (generic + tracing + LED)
Microchip LAN743x Gigabit Ethernet
PPP protocol support (async serial)
Realtek RTW88 Wi-Fi (8723D, 8723DU, 8723X, USB)
CH341 USB-to-serial converter
CRC-CCITT, compression libraries for PPP

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

l4t-differences is a skill published in the GitHub repository Seeed-Projects/Seeed-Jetson-DevelopTool (54 stars, last pushed today), licensed MIT. It adds 84 tokens to every session and 1,431 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
