# Libre Computer Board ALL-H3-CC

> Installing Talos on Libre Computer Board ALL-H3-CC SBC using raw disk image.

export const release_v1_7 = 'v1.7.6';

## Prerequisites

You will need

* `talosctl`
* an SD card

Download the latest `talosctl`.

<CodeBlock lang="sh">
  {`
    curl -Lo /usr/local/bin/talosctl https://github.com/siderolabs/talos/releases/download/${release_v1_7 }/talosctl-$(uname -s | tr "[:upper:]" "[:lower:]")-amd64
    chmod +x /usr/local/bin/talosctl
    `}
</CodeBlock>

## Download the Image

The default schematic id for "vanilla" Libretech H3 CC H5 is `5689d7795f91ac5bf6ccc85093fad8f8b27f6ea9d96a9ac5a059997bffd8ad5c`.
Refer to the [Image Factory](../../learn-more/image-factory) documentation for more information.

Download the image and decompress it:

<CodeBlock lang="sh">
  {`
    curl -LO https://factory.talos.dev/image/5689d7795f91ac5bf6ccc85093fad8f8b27f6ea9d96a9ac5a059997bffd8ad5c/${release_v1_7 }/metal-arm64.raw.xz
    xz -d metal-arm64.raw.xz
    `}
</CodeBlock>

## Writing the Image

The path to your SD card can be found using `fdisk` on Linux or `diskutil` on macOS.
In this example, we will assume `/dev/mmcblk0`.

Now `dd` the image to your SD card:

```bash
sudo dd if=metal-arm64.raw of=/dev/mmcblk0 conv=fsync bs=4M
```

## Bootstrapping the Node

Insert the SD card to your board, turn it on and wait for the console to show you the instructions for bootstrapping the node.

Create a `installer-patch.yaml` containing reference to the `installer` image generated from an overlay:
Following the instructions in the console output to connect to the interactive installer:

```bash
talosctl apply-config --insecure --mode=interactive --nodes <node IP or DNS name>
```

Once the interactive installation is applied, the cluster will form and you can then use `kubectl`.

## Retrieve the `kubeconfig`

Retrieve the admin `kubeconfig` by running:

```bash
talosctl kubeconfig
```

## Upgrading

For example, to upgrade to the latest version of Talos, you can run:

<CodeBlock lang="sh">
  {`
    talosctl -n <node IP or DNS name> upgrade --image=factory.talos.dev/installer/5689d7795f91ac5bf6ccc85093fad8f8b27f6ea9d96a9ac5a059997bffd8ad5c:${release_v1_7 }
    `}
</CodeBlock>
