[Detector Support]: Coral M.2 PCIe on Beelink EQ12?

[freechurros]

Describe the problem you are having

My idea: Replace the M.2 E key WiFi board(picture below) on the Beelink EQ12 mini PC with a Coral M.2 A+E key accelerator (single TPU)

Has anyone tried or know if this is possible?
I'm not completely sure but I believe this M.2 slot on the EQ12 is PCIe.
If it works from a technical perspective, I also wonder if it will fit, and if heat generation would be a problem, as the Coral board would be under the NVMe SSD.

Did you try this? Curious to know if it worked.

[freechurros]

I haven't tried this yet, still figuring out if it's a good idea.

Some people apparently used the NVMe slot for the Coral accelerator, and used the SATA interface for storage. I want to keep the NVMe storage and shove an M.2 Coral underneath it, since I don't need Wi-Fi.

Will update the thread if I get to try this.

[billchurch]

interested in this as well, seems like a good platform if it works.

I have this up and running and it's working pretty well.

I also don't need wifi, wanted to use the NVMe storage and keep the SATA tray clear so the fan isn't as choked.
Config setup:

<other camera stuff>

detectors:
  coral:
    type: edgetpu
    device: pci:0

ffmpeg:
  hwaccel_args: preset-vaapi

I'd read some conflicting advice about GPU acceleration using the N100 and eventually went with vaapi for simplicity.

@nicolinuxfr Do you have the single or dual TPU card? If it is dual you need to define two pci devices in frigate but not sure if the second is supported by motherboard. I would love to try it

[lantranbot]

I have the dual TPU card, but only one is working when connected to this slot.

3 camera's and inference speed of 6.81ms

Try the below configuration:

detectors:
  coral1:
    type: edgetpu
    device: pci:0
  coral2:
    type: edgetpu
    device: pci:1

Yeah that doesn't work, as it only sees 1 apex device. Something to do with how the E-key sockets work.
"Although the M.2 Specification (section 5.1.2) declares E-key sockets provide two instances of PCIe x1, most manufacturers provide only one. To use both Edge TPUs, be sure your socket connects both instances to the host."
Seems the EQ12 only has one on the wifi slot. Should be possible to fix by using an m.2 BM version (see https://github.com/magic-blue-smoke/Dual-Edge-TPU-Adapter ) but haven't tried that...

I was hoping that they had followed the standards... at least one is working.
Surprisingly, Beelink states in their forum that the wifi slot is not pcie but cnvi and that coral shall not work:
