CodeProject.AI Discussions

Hi everyone.
CodeProject environment:
-hw:raspberry PI5 8G+CoralUsb
-latest pi os lite 64Bit
-latest docker engine
Downloaded and installed the rpi64 2.5.6.1 docker image.
Disabled all modules and activated only the coral module (disable GPU, EfficientDetLite, Tiny, No MultiTPU).
Configured automatic boot.
Everything works fine but after a few hours the system no longer responds at blueiris call.
I have to restore it by restarting the coral module from the web interface (the log appears blocked) or with a system reboot.
Do you have any suggestions on what to do? What can I check?
Thank you
Mike
