1 - Banana Pi M64

Installing Talos on Banana Pi M64 SBC using raw disk image.

Prerequisites

You will need

  • talosctl
  • an SD card

Download the latest talosctl.

curl -Lo /usr/local/bin/talosctl https://github.com/siderolabs/talos/releases/download/v1.7.6/talosctl-$(uname -s | tr "[:upper:]" "[:lower:]")-amd64
chmod +x /usr/local/bin/talosctl

Download the Image using Image Factory

The default schematic id for “vanilla” Banana Pi M64 is 8e11dcb3c2803fbe893ab201fcadf1ef295568410e7ced95c6c8b122a5070ce4. Refer to the Image Factory documentation for more information.

Download the image and decompress it:

curl -LO https://factory.talos.dev/image/8e11dcb3c2803fbe893ab201fcadf1ef295568410e7ced95c6c8b122a5070ce4/v1.7.6/metal-arm64.raw.xz
xz -d metal-arm64.raw.xz

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:

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. Following the instructions in the console output to connect to the interactive installer:

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:

talosctl kubeconfig

Upgrading

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

talosctl -n <node IP or DNS name> upgrade --image=factory.talos.dev/installer/8e11dcb3c2803fbe893ab201fcadf1ef295568410e7ced95c6c8b122a5070ce4:v1.7.6

3 - Jetson Nano

Installing Talos on Jetson Nano SBC using raw disk image.

Prerequisites

You will need

Download the latest talosctl.

curl -Lo /usr/local/bin/talosctl https://github.com/siderolabs/talos/releases/download/v1.7.6/talosctl-$(uname -s | tr "[:upper:]" "[:lower:]")-amd64
chmod +x /usr/local/bin/talosctl

Flashing the firmware to on-board SPI flash

Flashing the firmware only needs to be done once.

We will use the R32.7.2 release for the Jetson Nano. Most of the instructions is similar to this doc except that we’d be using a upstream version of u-boot with patches from NVIDIA u-boot so that USB boot also works.

Before flashing we need the following:

  • A USB-A to micro USB cable
  • A jumper wire to enable recovery mode
  • A HDMI monitor to view the logs if the USB serial adapter is not available
  • A USB to Serial adapter with 3.3V TTL (optional)
  • A 5V DC barrel jack

If you’re planning to use the serial console follow the documentation here

First start by downloading the Jetson Nano L4T release.

curl -SLO https://developer.nvidia.com/embedded/l4t/r32_release_v7.1/t210/jetson-210_linux_r32.7.2_aarch64.tbz2

Next we will extract the L4T release and replace the u-boot binary with the patched version.

tar xf jetson-210_linux_r32.6.1_aarch64.tbz2
cd Linux_for_Tegra
crane --platform=linux/arm64 export ghcr.io/siderolabs/sbc-jetson:v0.1.0 - | tar xf - --strip-components=4 -C bootloader/t210ref/p3450-0000/ artifacts/arm64/u-boot/jetson_nano/u-boot.bin

Next we will flash the firmware to the Jetson Nano SPI flash. In order to do that we need to put the Jetson Nano into Force Recovery Mode (FRC). We will use the instructions from here

  • Ensure that the Jetson Nano is powered off. There is no need for the SD card/USB storage/network cable to be connected
  • Connect the micro USB cable to the micro USB port on the Jetson Nano, don’t plug the other end to the PC yet
  • Enable Force Recovery Mode (FRC) by placing a jumper across the FRC pins on the Jetson Nano
    • For board revision A02, these are pins 3 and 4 of header J40
    • For board revision B01, these are pins 9 and 10 of header J50
  • Place another jumper across J48 to enable power from the DC jack and connect the Jetson Nano to the DC jack J25
  • Now connect the other end of the micro USB cable to the PC and remove the jumper wire from the FRC pins

Now the Jetson Nano is in Force Recovery Mode (FRC) and can be confirmed by running the following command

lsusb | grep -i "nvidia"

Now we can move on the flashing the firmware.

sudo ./flash p3448-0000-max-spi external

This will flash the firmware to the Jetson Nano SPI flash and you’ll see a lot of output. If you’ve connected the serial console you’ll also see the progress there. Once the flashing is done you can disconnect the USB cable and power off the Jetson Nano.

11 - Raspberry Pi Series

Installing Talos on Raspberry Pi SBC’s using raw disk image.

Talos disk image for the Raspberry Pi generic should in theory work for the boards supported by u-boot rpi_arm64_defconfig. This has only been officialy tested on the Raspberry Pi 4 and community tested on one variant of the Compute Module 4 using Super 6C boards. If you have tested this on other Raspberry Pi boards, please let us know.

Video Walkthrough

To see a live demo of this writeup, see the video below:

Prerequisites

You will need

  • talosctl
  • an SD card

Download the latest talosctl.

curl -sL 'https://www.talos.dev/install' | bash

Updating the EEPROM

Use Raspberry Pi Imager to write an EEPROM update image to a spare SD card. Select Misc utility images under the Operating System tab.

Remove the SD card from your local machine and insert it into the Raspberry Pi. Power the Raspberry Pi on, and wait at least 10 seconds. If successful, the green LED light will blink rapidly (forever), otherwise an error pattern will be displayed. If an HDMI display is attached to the port closest to the power/USB-C port, the screen will display green for success or red if a failure occurs. Power off the Raspberry Pi and remove the SD card from it.

Note: Updating the bootloader only needs to be done once.

curl -LO https://factory.talos.dev/image/ee21ef4a5ef808a9b7484cc0dda0f25075021691c8c09a276591eedb638ea1f9/v1.7.6/metal-arm64.raw.xz
xz -d metal-arm64.raw.xz

Writing the Image

Now dd the image to your SD card:

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. Following the instructions in the console output to connect to the interactive installer:

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.

Note: if you have an HDMI display attached and it shows only a rainbow splash, please use the other HDMI port, the one closest to the power/USB-C port.

Retrieve the kubeconfig

Retrieve the admin kubeconfig by running:

talosctl kubeconfig

Upgrading

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

talosctl -n <node IP or DNS name> upgrade --image=factory.talos.dev/installer/ee21ef4a5ef808a9b7484cc0dda0f25075021691c8c09a276591eedb638ea1f9:v1.7.6
