overhead_mount_occupancy demo I have installed the software "overhead_3d_vod_demo.bin". then I tried to upload the cfg file a few times. and then the port stopped connecting at all. More precisely, the usb port always started to say it is ON. and the usb connection led on the board is always on. I'm sure nothing is connecting to the device.I could never connect to enhanced COM again. For this reason, I cannot update the software. Can you help me?
