Nah if it's the incorrect arch it should not even start

I suspect the rpi reports the arch as "aarch64" and in the code we only look for "arm64" when setting repository architecture.. I will have a closer look later tonight!

Sounds plausible, the error is coming from https://github.com/rancher/elemental-cli/blob/main/pkg/utils/common.go#L516

Weird, if the log is ok that is failing under NewRunConfig which calls NewConfig

ripe-mechanic-63260

10/18/2022, 3:29 PM

Which uses the runtime.GOARCH to know what the arch is

ripe-mechanic-63260

10/18/2022, 3:34 PM

That should be arm64 I think....

ripe-mechanic-63260

10/18/2022, 3:36 PM

Or is it still armv7?

ripe-mechanic-63260

10/18/2022, 3:41 PM

No no, pretty sure it's arm64

runtime.GOARCH

(doing a quick search) is set at compile time, so if it’s a 32-bit ELF… I doubt it’s going to say

arm64

ripe-mechanic-63260

10/18/2022, 3:46 PM

Oh I think I see what's wrong

ripe-mechanic-63260

10/18/2022, 3:46 PM

Kairos should have builds for both RPI<4 and rpi4

ripe-mechanic-63260

10/18/2022, 3:47 PM

Otherwise rpi1,2,3 are 32 bits and rpi4 is 64

ripe-mechanic-63260

10/18/2022, 3:47 PM

So running an armv7 under rpi4 will fail to find the correct aarch

ripe-mechanic-63260

10/18/2022, 3:48 PM

As it will report armv7 but we only support aarch64

happy-island-57258

10/18/2022, 3:51 PM

RPi3 should be 64-bit as well, but I suspect the proximal issue is that kairos recompiled

elemental-cli

on 32-bit arch, which sets

runtime.GOARCH

arm64

, which causes

GolangArchToArch

to return “invalid arch”.

ripe-mechanic-63260

10/18/2022, 3:52 PM

Probably should open a ticket under kairos to have separated builds for rpi64 and rpi32 bits or under elemental-cli so we support armv7 as an arch

ripe-mechanic-63260

10/18/2022, 3:54 PM

Although in not sure we are able to support armv7 properly...we could at least add the arch in there so it doesn't fail like that

ripe-mechanic-63260

10/18/2022, 4:08 PM

Ugh can't believe we don't have a proper message that spits out the arch we could not identify...I'll fix that

I see that Rancher OSv2 bundled Rancher Manger in some configurations: https://rancher.github.io/os2/#use-cases Any plans to pre-install Rancher on Elemental or must I do that myself?

does the 1.0.0 release signal "stable"?

Hi, Im I correct to assume that the when using emulate-tpm, the tpmhash is bound to the built iso? No tpm support in my current vcenter so testing emulation. Booting multiple vms from same iso has the same hash, hence only one entry in mchineinventory.

shy-hamburger-95730

12/05/2022, 12:58 PM

Is there are a way to utilize ranchers cluster feature to spin up/scale the actual vms for elemental?

How would one install rancher itself on elemental? I saw @ripe-mechanic-63260s "watson" PoC, but I fail to see how to register multiple nodes to it? I could create a elemental cluster via rancher, then install rancher on it, I suppose. But "rancher in rancher" didnt work last time I tried it, iirc.

Howdy ! Just in time for the x-mas break, we've added instructions how to run Elemental on Raspberry Pi ! Just head over to our development documentation and follow the instructions. If you have other ARM boards you want to run Elemental on, we'd love to hear from you.

Hey Ethan, for that you could build your own iso. The default user/pass for the iso is located on https://github.com/rancher/elemental/blob/main/framework/files/system/oem/04_accounting.yaml so you could modify that and then build your iso with the

make build && make iso

targets

Hey all! Just kicking the tires on the new Elemental on Raspberry Pi instructions. One quick piece of feedback, when I was using a newer LG 4k monitor, the screen would go black toward the end of the Elemental boot process and would not come back. I switched to an older (not 4k) Dell monitor and the screen comes back at that part of the boot process. I'm assuming a driver or resolution issue but just wanted to throw it out there for those working on the new releases of the TEAL Elemental for Pi. Thanks!

thanks for the feedback. To be transparent, I don't think we're going to pursue hard to have video / hdmi support. Our purpose is rather to achieve headless installs, deployments and management

strong-shoe-72392

01/06/2023, 1:30 PM

Sure. That's understandable. However, until it's far enough along in the boot process and you can SSH into the Pi, it is useful in troubleshooting startup issues. I know the first time I tried burning the ISO to USB, there was an issue and the SLE Micro didn't get far enough along to SSH.

careful-piano-35019

01/06/2023, 1:31 PM

you can use the console access, provided you have the suitable cable

strong-shoe-72392

01/06/2023, 1:32 PM

Oh ok. I'll have to look into that. Thanks

I'm doing it under Linux, so I'll be able to share Linux oriented instructions if that helps

strong-shoe-72392

01/06/2023, 1:38 PM

I'm using a Mac, but yes this all helps if you have anything else to share.

careful-piano-35019

some of the instructions are similar. Not sure about the drivers though (it's included with openSUSE)

https://uk.rs-online.com/web/p/raspberry-pi-cables/7676200 like this cable, but that's a very expensive price

https://www.kubii.fr/hub-cables-adaptateurs/1761-cable-usb-vers-ttl-4-pin-kubii-3272496006263.html I paid about 4 or 5€

Thank you! Did you see my other post in this channel? Curious if you or anyone else has any thoughts as to why it's failing to register the Pi as machine inventory. I was able to successfully do this with a VirtualBox VM node but not the Pi following the new Pi instructions.

Kernel crash on Raspberry is a driver/kernel problem: https://bugzilla.suse.com/show_bug.cgi?id=1196855 😞
