[Detector Support]: N150 Beelink EQ14 - how to enable Coral M.2 TPU

[jdesai61]

Describe the problem you are having

I was running frigate in a VM over proxmox on an Intel NUC with Coral M.2 TPU. I was running out of memory on the NUC, so decided to purchase a separate computer for frigate and chose Beelink EQ14. I took the Coral M.2 card from NUC's WiFi slot and moved it over to EQ14 (by replacing it's WiFi M.2 card). On the EQ14 I skipped proxmox and installed Ubuntu directly.

However, Ubuntu (20.04, 22.04 or 24.04) refuses to acknowledge the card even exists. I followed instructions on coral.ai, but

lspci -nn | grep 089a

does not show any coral card. Nor does any /dev/apex_* device show up.

Has anyone had any luck with using Coral M.2 in EQ14? I notice folks here are using EQ12... Perhaps there is a reason for this?

@jdesai61 I think there is a defect in the gasket driver that the folks at Google created for the Coral M.2. You'll need to download an install a different version. If you look around the internet, you'll see different implementations. For example, here's a discussion of how to do it on Proxmox https://forum.proxmox.com/threads/how-to-install-coral-m-2-pci-passthrough-for-frigate-on-proxmox-8.145557

Also, I've seen discussion here #15900 (comment) that the N150 is a very new cpu and that is iGPU isn't supported in the linux kernel that ships with Ubuntu 24.04. So you might need to wait for the next version of Ubuntu or manually upgrade the kernel yourself.

I had errors installing drivers on 24.04, so I went back to 22.04 and 20.04 LTS versions where drivers installed just fine - they just don't seem to recognize the card. I might have to fiddle with BIOS or such.

I just came across the same issue. Just wondering if you've come across a solution yet?
