Home Assistant Yellow CM5 only green LED on constantly?

Installation

1

Hi,

I just got a brand new Home Assistant Yellow with the CM5 module and I tried installing it the first time with the Raspberry Pi Imager as instructed, but after completed flashing all that happened when I powered it up was the red LED lighting up for a short moment and the the green LED being the only one on constantly.

I tried re-installing but no change.

Then I found a backup-guide to re-install the OS that I used:
https://yellow.home-assistant.io/guides/issue-while-installing-os-on-emmc/

So this guide was for an alternate issue, but none the less it worked for me following it.

So I had the HA directly cabled via USB-C and moved the jumper.

The latest current version, in writing moment is this one, just for the ease for you: https://github.com/home-assistant/operating-system/releases/download/14.0/haos_yellow-14.0.img.xz.

Otherwise visit the release-page that is linked in the guide, and remember to click “show all assets”, otherwise you won’t see the HA Yellow OS.

So just remember when you get to Step 3 in the normal guide (which the guide links to as well), to use the OS you downloaded yourself.

Hope it can save someone the same troubles it caused me :slight_smile:

Best,
Martin

I had the same experience, here’s what I did to get around it. I happened to have a spare nvme drive laying around so I flashed it using an nvme->USB dongle and the Raspberry Pi Imager software, using the latest HAOS14 found here

https://github.com/home-assistant/operating-system/releases/download/14.0/haos_yellow-14.0.img.xz

After flashing, I popped it into the Yellow gave it a few minutes and then was able to connect via homeassistant.local:8123

I think the same might apply if you were to use a USB stick too, to download onto the on device storage but not 100% sure. Hope this helps.

Hi guys,

No joy for me i’m afraid.

I have reinstalled from the backup with my CM4 and then followed these instructions (https://support.nabucasa.com/hc/en-us/articles/25608040264093-Migrating-from-CM4-with-NVMe-to-CM5-with-NVMe) to upgrade to a CM5 lite but i just get the solid green LED after a supposed successful rpiboot.

I have also tried to flash the nvme with the @virtualuk link as above but that still has the same outcome.

Does anyone else have any ideas?

I have the same issue. I’ve had a CM4 with NVMe and now migrated to CM5 Lite with NVMe and got this issue.

So far no idea what to do.

I migrated from a CM4 to a CM5 and also replaced the NVMe for a new one, so I would like to install fresh, but I put the USB stick I imaged using RPI Imager, but just got steady green light.

I’m on the same boat here, I tried installing another SSD, booting from an USB stick but the results were all the same.

I bought a Home Assistant Yellow PoE with a CM5 from Seeed Studio, but seem to be having the same issue as reported by others here. Quite frustrating. Are there any other potential workarounds?

EDIT: As it turns out, the instructions here were effective

I think the problem I was having was a USB-C to USB-A cable that wasn’t rated for data (just power) when I connected it to my laptop to use rpiboot.

Thanks a million, this worked for me, was tearing my hair out trying to get my Home Assistant Yellow to boot after installing a new NVME drive after my last one failed.
