[Detector Support]: Hailo M.2 on pcie3 double HAT. #21631
Describe the problem you are havingI have a hardtime to run HAILO on RPI5 with Home Assistant OS. Anyway even when trying to follow - disabling the driver, and loading the new one, I alread fail at the step no.:4 : update-initramfs -u The HAILO is not detected, even cannot see it in /system/hardware. When I boot to raspberry OS, instead of HA OS, i can see the HAILO by lspci. So the hardware is not bricked. Version0.16.3-9034454 Frigate config fileMqtt:

The error When using Home Assistant OS, the Hailo driver installation process differs significantly from standard Docker installations. The installation script documented in the standard installation guide is designed for standard Linux systems, not Home Assistant OS(1). Home Assistant OS needs to have Hailo driver support built into the OS itself(1). Key Points for Home Assistant OS:
Troubleshooting Steps:
detectors:
hailo:
type: hailo8l
device: PCIeThe issue is that Home Assistant OS isn't exposing the Hailo device to the Frigate container. Since the manual driver installation steps don't apply to Home Assistant OS, you'll need to ensure your Home Assistant OS version includes proper Hailo support, and you're using the correct Frigate add-on variant designed for Hailo devices(2). If you're running an older version of Home Assistant OS (below 14.0), you may need to upgrade to get Hailo support(2). 📚 Sources:

You may want to check with HA OS support, as if it doesn't show up in hardware Frigate won't be able to use it |
|
It seems that there is a problem with M2 double HAT and HA OS driver as you said 👍 [core-ssh ~]$ dmesg | grep -i pcie |

Found a solution, maybe was clear from beginning, but Im complete amateur: to config.txt Now Hailo is working in HA OS with Frigate addon, |

Thanks for sharing your answer |
Found a solution, maybe was clear from beginning, but Im complete amateur:
I had to put :
dtparam=pciex1
dtparam=pciex1_gen=3
dtoverlay=pciex1-compat-pi5,no-mip,mmio-hi
to config.txt
Now Hailo is working in HA OS with Frigate addon,
