Coral Dev Board config

[racingpassion]

Hi there is there a configuration file for the Coral Dev Board, bare metal using docker.?
I have a coral dev board with docker and frigate installed but I get the following errors :- standard_init_linux.go:228: exec user process caused: exec format error ,I'm assuming it's to do with the configuration is there any more details on using this board & setup, thanks.
PS: I'm surprised more people aren't using the death board is there a reason for this.?

This is the docker compose file I use:

services:
  frigate:
    container_name: frigate
    privileged: true # this may not be necessary for all setups
    restart: unless-stopped
    image: blakeblackshear/frigate:stable-aarch64
    shm_size: "768mb" # update for your cameras based on calculation above
    devices:
      - /dev/apex_0:/dev/apex_0
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - /home/mendel/frigate/config:/config:ro
      - /home/mendel/frigate/media:/media/frigate
      - type: tmpfs # Optional: 1GB of memory, reduces SSD/SD Card wear
        target: /tmp/cache
        tmpfs:
          size: 1000000000
    ports:
      - "5000:5000"
      - "1935:1935" # RTMP feeds
    environment:
      FRIGATE_RTSP_PASSWORD: "password"

I don't understand what you mean about CPU timings - it all appears to start up within a second.
You're getting complaints abut using CPU detectors, when you should only be using the edgetpu (if I understand correctly).

When I had 2 instances using the same mqtt broker with the same ID, then nothing worked properly. I had to stop one of the instances before I got any functionality.
If it helps, my config is

mqtt:
  host: mqttserverIP
detectors:
  coral:
    type: edgetpu
    device: ''

cameras:
  Drive:
    ffmpeg:
      inputs:
        - path: rtsp://....
          roles:
            - detect
            - rtmp
    detect:
      fps: 5
  Eggshed:
    ffmpeg:
      inputs:
        - path: rtsp://....
          roles:
            - detect
            - rtmp
    detect:
      fps: 5

  House:
    ffmpeg:
      inputs:
        - path: rtsp://....
          roles:
            - detect
            - rtmp
    detect:
      fps: 5

Thanks that's pretty much what I've got, how many cameras are you running I'm running three at the moment, if I add 4 it doesn't seem as responsive.

When you are talking about CPU timings, are you referring to the 249,251,253, etc in your log output?
If so, those are just the process ID's. If you are looking for the inference speed, you'll find that in the UI on the debug page, or on the frigate/stats topic on your mqtt.
Will look something like this: "detectors": {"coral": {"inference_speed": 6.44 ...

Adding a 4th camera pushed the CPU usage to the limit for the first few minutes, with kswapd0 hogging the CPU. Once that calmed down, things seem to perform as usual.
This seems to imply that there's a problem with swap settings, and I can't find a swap partition or a swapfile.

@pjfian Thanks, got it ,me being clueless again.
