Hailo8 runs the Yolo detection program in Hef format and freezes occasionally

Hello everyone! I’m running the Yolo detection program on a Raspberry Pi with Hailo 8 as the acceleration module. After about half an hour of operation, the detection froze . When I restarted, the system failed to detect the Hailo 8 module. Does anyone know why this happened? Is there a hardware issue? Could it be related to voltage or connectivity problems? Or perhaps other factors?(I’ve encountered similar issues when running Hailo 8L.)

error:( the detection froze and I operate to exit it)

Hey @Ethan ,

Welcome to the Hailo Community!

Looks like you’re running into a connectivity issue where the system can’t open the device. This could be a couple of things - might be a kernel compatibility problem or just a general connectivity hiccup.

Mind running these commands for me so I can take a look at what’s going on? Just paste the output here when you get a chance:

uname -r
ls -l /dev/hailo*
dmesg -T | egrep -i 'hailo|pcie|aer|nvme|reset|link|voltage|throttl'
lspci -nn | egrep -i '1e60|hailo|accel'
hailortcli scan
hailortcli fw-control identify

Let me know what you find and we’ll get this sorted out for you!
