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.
