## What it does

The skill integrates MIPI and GMSL camera sensors into Jetson Thor (Tegra264) and Orin (Tegra234) hardware targets. It scans in-tree `.dtsi` files dynamically rather than relying on a static lookup table. After resolving the target carrier, it expands the relevant DTSI with `cpp`, extracts the sensor `fragment@N`, and appends it to your composite overlay `.dts`.

CSI cameras run on their own physical pool and bypass UPHY lanes. Because of this, the skill leaves `ODMDATA` alone in the carrier configuration, avoiding accidental changes to bus assignments. Registering both your rendered overlay and the vendor devkit overlay will create a phantom device binding. The skill enforces a single-fragment approach to prevent this enumeration failure.

You need `dtc`, `cpp`, and `fdtoverlay` installed on your system PATH. The BSP tree must already be initialized via `/jetson-init-source` and `/jetson-derive-carrier`. If carrier schematics or pinmaps are missing from the workspace, the wiring cross-check cannot complete.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-customize-camera -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/jetson-customize-camera/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/jetson-customize-camera/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-customize-camera -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/jetson-customize-camera/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-customize-camera -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/jetson-customize-camera/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**

npx skills add NVIDIA/skills --skill jetson-customize-camera -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/NVIDIA/skills --path skills/jetson-customize-camera
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/jetson-customize-camera/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**

npx skills add NVIDIA/skills --skill jetson-customize-camera -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/NVIDIA/skills/tree/HEAD/skills/jetson-customize-camera/SKILL.md

## When to use it
- attach MIPI and GMSL sensors to Jetson Thor and Orin custom boards
- fix missing tegra-capture-vi channels in v4l2-ctl --list-devices output
- build composite device tree overlays without manual cpp preprocessing
- validate camera control pin multiplexing with pin_verifier.py

## Example prompts
- Enable the IMX camera sensor on our custom Orin carrier board
- Configure CSI wiring for a GMSL camera on Jetson Thor
- Fix tegra-capture-vi channel enumeration on a new carrier daughter-card

# Customize camera (CSI / MIPI / GMSL sensor bring-up)

## Overview

Tegra264 (Thor) and Tegra234 (Orin) expose a single `tegra-capture-vi`
controller fronted by NVCSI and a fixed set of CSI ports. Camera
bring-up is:

1. **Sensor selection** — picked from the set NVIDIA ships in-tree
   `.dtsi` references for on the active platform.
2. **Carrier + module support check** — verified against the Camera
   Development Guide, Adaptation Guide §Camera, carrier schematic,
   Module TRM, and carrier pinmap.
3. **Wiring** — derived from the in-tree
   `tegra<soc>-camera-<sensor>*.dtsi` when one exists (**the DTSI IS
   the wiring source of truth**); captured per-sensor from the user
   when the sensor is custom.
4. **Kernel-DT overlay** — cpp-expand the in-tree DTSI, extract its
   `fragment@N` body, append into the composite custom overlay
   `.dts` for the active target (per
   [`../../references/bsp-customization-kernel-dtb.md`](../../references/bsp-customization-kernel-dtb.md)),
   verify the composite with `fdtoverlay`.
   `/jetson-build-source` compiles the composite and owns the
   carrier conf's `OVERLAY_DTB_FILE+=` registration.

**Agentic, not table-driven** — sensor list is built at runtime by
globbing in-tree per-sensor dtbos. No `_THOR_CAMERAS` dict, no
`questions.json`, no Python renderer in the question path.

**No ODMDATA edit** — cameras don't consume UPHY lanes (CSI is a
separate PHY pool). The skill emits only a kernel-DT overlay; the
ODMDATA line in the carrier conf is untouched by this skill.

The output is **one commit**:
- Camera `fragment@N` block (plus `jetson-header-name` on the
  composite root if not already present) appended to the composite
  custom overlay `.dts` per
  [`../../references/bsp-customization-kernel-dtb.md`](../../references/bsp-customization-kernel-dtb.md)
  → committed to the `bsp_sources/` hardware repo.
  `/jetson-build-source` compiles the composite to `.dtbo` and
  owns its Makefile + flash-conf registration.

## When to invoke

- The user says "enable camera", "configure CSI", "wire a Hawk /
  Owl / IMX sensor", "MIPI camera", "GMSL camera", or asks to bring
