Raspberry Pi 5 Talos Builder

This repository serves as the glue to build custom Talos images for the Raspberry Pi 5. It patches the Kernel and Talos build process to use the Linux Kernel source provided by raspberrypi/linux.

Tested on

So far, this release has been verified on:

✅ Hardware
Raspberry Pi Compute Module 5 on Compute Module 5 IO Board
Raspberry Pi Compute Module 5 Lite on DeskPi Super6C
Raspberry Pi 5b with RS-P11 for RS-P22 RPi5

What's not working?

• Booting from USB: USB is only available once LINUX has booted up but not in U-Boot.

How to use?

The releases on this repository align with the corresponding Talos version. There is a raw disk image (initial setup) and an installer image (upgrades) provided.

Examples

Initial:

unzstd metal-arm64-rpi.raw.zst
dd if=metal-arm64-rpi.raw of=<disk> bs=4M status=progress
sync

Upgrade:

talosctl upgrade \
  --nodes <node IP> \
  --image ghcr.io/talos-rpi5/installer:<version>

Building

If you'd like to make modifications, it is possible to create your own build. Bellow is an example of the standard build.

# Clones all dependencies and applies the necessary patches
make checkouts patches

# Builds the Linux Kernel (can take a while)
make REGISTRY=ghcr.io REGISTRY_USERNAME=<username> kernel

# Builds the overlay (U-Boot, dtoverlays ...)
make REGISTRY=ghcr.io REGISTRY_USERNAME=<username> overlay

# Final step to build the installer and disk image
make REGISTRY=ghcr.io REGISTRY_USERNAME=<username> installer
