Hi,
I’m using YOLOv4 and ZED camera to do object detection and distance calculation. The camera and software terminal window freeze after 1-2 hours (they grey out) while other part of the Ubuntu OS works fine. If I disconnect the HDMI cable connecting the board to a monitor and reconnect it right away, the software starts working. Has anybody seen such a behavior?

Thanks,
–Kash

Hi Kash,

Dumping the serial console log could help us know what happens when the terminal freeze.
