## What it does

The skill initializes the Jetson BSP directory for an active target profile. It locates local kernel and sample root filesystem tarballs, unpacks them into the designated image path, and runs `apply_binaries.sh`. The script selects the proper GPU driver stack based on the module hardware, passing the `--openrm` flag for Thor hardware and omitting flags for Orin modules.

Once extracted, the skill validates the installed driver stack against the active target contract and records the derived release version in the `bsp_image` block of the profile. If a `Linux_for_Tegra` directory already exists on disk, the skill halts to avoid overwriting files without explicit user consent.

Tarballs must be staged on disk beforehand because this skill does not download packages. Running `apply_binaries.sh` requires root privileges through `sudo`, and omitting an active target profile causes an immediate halt.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install NVIDIA/skills jetson-init-image
```

2. **Manually: put the files in place**
- File: `.github/skills/jetson-init-image/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-init-image -a gemini-cli
```

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-init-image -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-init-image/SKILL.md

## When to use it
- extract Jetson Linux and sample rootfs archives
- run apply_binaries.sh with target-derived GPU stack flags
- record BSP image paths and versions in the active profile
- prevent accidental overwrites of existing rootfs directories

## Example prompts
- Extract the Jetson BSP image and apply binaries for the active target
- Initialize the Linux_for_Tegra directory from tarballs in Image

# Initialize BSP Image

Output is only `bsp_image:` in the active profile: derived `version`
plus `root_path` only when overriding `<workspace>/Image`.

## When to invoke

- The user asks to extract, prepare, or initialize the BSP image.
- A downstream skill reports missing
  `<bsp_image.root_path>/Linux_for_Tegra/`.
- The active profile has no `bsp_image:` block yet.

## Procedure

### Resolve target and image path

Resolve the active profile per
[`../../context/target-platform-contract.md`](../../context/target-platform-contract.md).
Refuse if there is no active profile or `reference_devkit:` is missing.

`<workspace>` is the parent of the active profile's `target-platform/`
directory. `<bsp_image.root_path>` defaults to `<workspace>/Image`.

| Profile state | Action |
|---|---|
| `bsp_image.root_path` exists | Use it without prompting. |
| `bsp_image:` exists without `root_path` | Use `<workspace>/Image`. |
| No `bsp_image:` block | Ask once: Enter for default, or absolute override path. |

For an override, validate that the closest existing parent is writable.
Omit `root_path` when the default is used.

### Determine GPU stack

Use the shared GPU-driver invariant from
[`../../context/target-platform-contract.md`](../../context/target-platform-contract.md#derived-platform-facts).
Derive the expected stack from `reference_devkit.module.id` and the
catalogue:

| Chip family | Module IDs | Stack | `apply_binaries.sh` flag |
|---|---|---|---|
| T234 / Orin | `p3701`, `p3767` | nvgpu | none |
| T264 and later / Thor+ | `p3834` | OpenRM | `--openrm` |

Refuse unknown module IDs. The `--openrm` flag is only valid on BSP
releases that ship the OpenRM stack; if the active BSP doesn't expose
the flag, omit it regardless of what the target wants.

### Reuse or extract

If `<bsp_image.root_path>/Linux_for_Tegra/` already exists:

1. Do not extract over it unless the user explicitly requested
   re-extraction and accepted the overwrite risk.
2. Derive the on-disk version from `Linux_for_Tegra/nv_tegra_release`.
   Ask before replacing a different recorded `bsp_image.version`.
3. Verify the installed GPU stack against the platform-derived
   expectation when possible. Detection precedence (first probe that
   yields a definitive answer wins):

   1. `Linux_for_Tegra/rootfs/etc/nv_tegra_release` carries an
      `INSTALL_TYPE=` token on BSP releases that expose it (newer
      lines). Read and compare directly.
   2. Otherwise, `find Linux_for_Tegra -name nvgpu.ko`: present →
```
