RPi5 is unable to boot

[samip5]

Trying to boot Talos 1.8.0 with RPi5, results in just a mostly black screen with the u-boot logo on top right.

NOTE: I did try to use the UEFI loader for Pi5, and that is able to boot until it appears to lack network driver in kernel so it cannot properly boot even if we get into Talos.

There's no support for RPi5, and RPi5 is only supported with more recent Linux than the LTS 6.6. we're currently using

Not entirely correct, as mainline kernel lacks ethernet support on RPi5 due to the way it's handled there (RP1 chip is responsible for it, https://www.raspberrypi.com/news/rp1-the-silicon-controlling-raspberry-pi-5-i-o-designed-here-at-raspberry-pi/), so it can bare minimally boot on newer kernel, but that's pretty much it at the moment.

Hi @samip5 any progress with maybe a uboot patch? It seems you are correct and
head Makefile -n 4 on my RP5 running OS LTE 64 returns

VERSION = 6
PATCHLEVEL = 6
SUBLEVEL = 51

and i see talos 1.8.2 is 6.6.58 so my thinking is how do I stop RP1 from handling ethernet via patch?

It would be best served to put uboot into the trash bin, and use systemd-boot instead for it.

You don't. The Pi5 architecture makes that impossible and Raspberry Pi OS LITE uses different kernel than Talos does.

I'm only using RPi OS Lite since i was able to install proxmox on it (link) but I want talos on bare metal. Were you able to achieve this via systemd-boot?

Not yet, as haven't yet figured out the proper way to install UEFI loader first onto it. https://github.com/skyssolutions/talos-sbc-raspberrypi

Have you looked into
https://github.com/worproject/rpi5-uefi?tab=readme-ov-file#supported-peripherals-in-uefi

I thought about using an ethernet adapter (link) but still not sure how to install UEFI loader first. Maybe an overlay and somehow set "ip=:::::eth1:dhcp"

This is way outside my skill set and just thought i'd pass along.

[samip5]

I have looked at that and that's precisely what I'm trying to use for it.

Any luck on this? I just got four Raspberry Pi 5s for Christmas, and I am dying to get a bare-metal Talos cluster running!

NVME boot doesn't work, SD card boot works and the mainline kernel talos uses cannot use ethernet.

Does Talos use only LTS kernel versions? Do we need to wait until the next LTS release is out for ethernet to work?

Yes, but at the moment the latest LTS 6.12.x Linux kernel is the latest Linux kernel release available as well, fyi.

Will not work either. Support hasn't been upstreamed yet while work to do that is ongoing.
Have to use Raspberry Pi Foundation's kernel for the moment.

I got UEFI + NVME boot to work, but when kernel boots loop driver is missing.
Used worproject/rpi5-uefi and the dtb file from raspberrypi's repo (did not use u-boot).

Got this error while booting talos:
mrecovered from: early boot failed: error mounting "/dev/loop0": error mounting: 1 error(s) occurred: no such device

Has anyone managed to build talos using official/patched raspberrypi linux kernel?
Have not tried to set up kernel build with extra talos required config myself yet..

Hi,

I have three Raspberry Pi 5 to create a small bare metal k8s cluster. I'd love to use Talos from the start but I am struggling with understanding the current state of affairs. Obviously, there is no official support. Several people are trying to get Talos working on this hardware, with more or less success. I tried to follow what some others said, but couldn't make sense of it.

Given my setup as an example, could someone more knowledgeable explain if this is possible at all at the moment?

• 3x Raspberry Pi 5
• USB thumb drives as boot/os drive
• NVMEs for additional storage
• PoE for power
• connected via Ethernet

For any of your peripherals to work:

• Requires the use of Raspberry Pi Foundation kernel
• nvme nor Ethernet are supported in mainline kernel

they are provided via the RP1 IO microcontroller which is not supported fully at the moment.
