Hey @kok.bing,

Welcome to the Hailo Community!

It looks like you’re experiencing a driver issue. I noticed that you set the descriptor page size to 4096 and ran some operations on the driver. Could you try running the hailortcli scan without these changes?

If the issue persists, please remove the driver and all related {hailo}.ko files, then reinstall the driver and check if the module can be found.

 rm /lib/modules/6.6.31+rpt-rpi-2712/kernel/drivers/media/pci/hailo/hailo_pci.ko.xz
  1. Install hailort-pcie-driver_4.18.0_all.deb instead of the driver I compiled and installed
