@hwjalapeno the only thing that this overlay does is disabling hdmi so I guess you just can't expects to be able to use the display, other than that I don't anticipate any other heads up. You are running edgetpu_classify_server which is trying to sink the images to a display using glimagesink. That's definitely isn't going to work.

So assuming I will recompile the model with this addition tomorrow

you wouldn't have to recompile the model, just try using the headless pipeline

Sure, will check it out, @borguleabhijeet , thanks!

@borguleabhijeet nice!!

@Namburger Thanks

Hey, tried out your code on Google Coral

This is the warning log, we are not able to stream it on VLC as well as online RTSP servers,

Could you help us out here?

Its works you should be installing the following package
sudo apt install gir1.2-gst-rtsp-server-1.0
Next, change the frame height and width which is currently 1280x720-->640x480 in both gstreamer pipeline cap.set or comment on it .
Finally, please use /test after the IP address and port as in the following example,
rtsp://192.168.0.1:8558/test
See the working example below

Sure thanks a lot, will check it out

Hi @Namburger

Found this in the Google Coral SoM Documentation

"HDMI reference clock (27 MHz) (positive/negative).  Required for bootup , even if you don't use HDMI.  "

This is blocking me to access the EdgeTPU for any application, it basically fails to detect the EdgeTPU with your device tree overlay, is this usual, or are you able to use it without this clock, , is there any way to disable this clock so that I can use the EdgeTPU properly? Thanks

@hwjalapeno it does not blocks you from accessing the EdgeTPU in any form. As I already mentioned here, your issue is that the application is trying to sync your result to a monitor which fails. There are 2 things that we suggested:

• Have you tried using the headless pipeline as I mentioned?
• @borguleabhijeet showed you how to sync the resulting buffer to a remote monitor via rtsp and it worked for him, did you try that?

Hi, there is no need of 27 Mhz clock. just compile and place the file at /boot. The project page I shared about the door lock FR system, has no clock pin associated with it. I also found that the wifi module and TPU accelerator is on pci lines which sometimes fails to detect the device when u try to access wifi a lot via nmcli or connect functions. This happens due to unexpected kernal failure. So, I recommend you to flash and rebuild your device on dev board, build the dtc file using above code, place at boot, and transfer the SoM at ur custom HDC. Thanks, Abhijeet

So initially work with USB-c lan and avoid working with the WiFi. I also discussed this here A soln just for your future errors. google-coral/edgetpu#589 (comment) On Wed, Dec 14, 2022, 1:18 AM Abhijeet Borgule ***@***.***> wrote:
