The coral is very slow. It always shows 162ms

[nguyenvanchiem]

I install latest version (0.14.1) and have coral ls /dev/apex* show /dev/apex_0
The basic config in Frigate

mqtt:
enabled: false
detectors: # <---- add detectors
coral:
type: edgetpu
device: pci
cameras:
test: # <------ Name the camera
enabled: true
ffmpeg:
inputs:
- path: rtsp://192.168.1.44:39423/a42e6c77cee82b0f # <----- The stream you want to use for detection
roles:
- detect
detect:
enabled: false # <---- disable detection until you have a working camera feed
version: 0.14

But the coral is alsway high. The coral is very high as image below. it is alsway 162. Do you have advice for this case?

[NickM-27]

you need to answer all of the requested information

[nguyenvanchiem]

Yes. I tried 2 case. However the result is the same.
Case 1: use the PCIE 1x to M2 M, then M2 M to M2 E key
Case 2: use PCIE 1x to mini PCIE, then mini PCIE to M2 E key

that's odd, perhaps there is some inefficiency introduced. Try looking at dmesg on the host

[nguyenvanchiem]

The dmesg shows
[ 472.300374] pcieport 0000:00:06.0: [ 6] BadTLP

Is it cause?

[nguyenvanchiem]

Tried with other machines, but the result is the same.

[NickM-27]

that is very odd, it might be possible that the coral is problematic if multiple servers show the same behavior, the dmesg does seem to indicate some type of error.
