Hey @g_r ,
Welcome to the Hailo Community!
This issue you are facing means the Hailo PCIe driver wasn’t built and installed for your new kernel.
Here’s how to fix that and get everything working again.
Hailo Driver Needs to Match Your Kernel
The HailoRT use a custom kernel driver called hailo_pci to talk over PCIe. Since it’s an out-of-tree module, it has to be compiled for your exact kernel — including:
- Same kernel version (e.g.
6.9-rt) - Matching kernel headers
- Same compiler and config
How to Rebuild the Driver for Your RT Kernel
Here’s the process, pulled from the HailoRT docs and install scripts:
-
Install headers for your current kernel
sudo apt install linux-headers-$(uname -r) -
Clone the HailoRT driver repo
git clone --depth 1 --branch v4.20.0 https://github.com/hailo-ai/hailort-drivers.git cd hailort-drivers/linux/pcie -
Build and install the PCIe driver
sudo make all sudo make install -
Load the driver
sudo modprobe hailo_pci -
Install firmware
cd ../../ ./download_firmware.sh sudo mkdir -p /lib/firmware/hailo sudo mv hailo8_fw.*.bin /lib/firmware/hailo/hailo8_fw.bin -
Install udev rules
sudo cp ./linux/pcie/51-hailo-udev.rules /etc/udev/rules.d/ sudo udevadm control --reload-rules && sudo udevadm trigger -
Reboot and test
sudo reboot
Once you’re back up:
hailortcli fw-control identify
Hopes this fixes the issue!
