Hi, I need your help regarding my Hailo 8 M.2 (M-key version).
In short: I am trying to get the hailort-driver working on my Raspberry Pi 5 running Ubuntu Desktop 24.04.01 LTS with kernel: 6.8.0-1018-raspi
, but it won’t work.
I’ve tried to install the following hailort-driver versions:
- v4.17.0
- v4.19.0
- v4.20.0
I’ve installed them like this:
sudo apt install linux-headers-$(uname -r)
sudo apt install build-essential
git clone https://github.com/hailo-ai/hailort-drivers.git --branch v4.17.0
cd hailort-drivers/linux/pcie
make all
sudo make install
cd ../..
./download_firmware.sh
sudo mkdir -p /lib/firmware/hailo
sudo mv hailo8_fw.4.17.0.bin /lib/firmware/hailo/hailo8_fw.bin
sudo cp ./linux/pcie/51-hailo-udev.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules && sudo udevadm trigger
sudo modprobe hailo_pci
sudo reboot
I also tried to build using this flag without success:
...
cd hailort-drivers/linux/pcie
make all CFLAGS="-DHAILO_RASBERRY_PIE"
sudo make install
...
Description of the issue:
The result is the same: the expected device (a node like /dev/hailo or a folder /dev/hailo*) is not created.
Even though a udev rule (51-hailo-udev.rules) is installed to adjust the permissions for devices under the hailo_chardev subsystem, the driver itself does not create the device node.
When loading the kernel module with sudo modprobe hailo_pci, I get the following messages:
sudo dmesg | grep -i hailo
[ 107.632053] hailo_pci: loading out-of-tree module taints kernel.
[ 107.632871] hailo: Init module. driver version 4.17.0
It seems that the device is not properly initialized; a lot of the expected initialization information is missing.
Additionally, lsmod shows that the kernel module is loaded but not used (usage count is 0):
lsmod | grep hailo
hailo_pci 110592 0
Expected behaviour would be:
ls /dev/hailo*
/dev/hailo0
sudo dmesg | grep hailo

I found an information mentioned by omria in in the Hailo forum regarding Linux kernel dependencies for hailort-driver versions ≤ v4.18.0 on Linux Kernel 6.5:
The latest update for Raspberry Pi OS (based on kernel 6.6) states:
stable_20250127: drivers: media: pci: Update Hailo accelerator device driver to v4.20
Now, with Ubuntu Desktop 24.04.01 I can’t downgrade below linux kernel 6.8.0…
According to the changelogs for hailort-driver v4.20.0, there is kernel support for Linux kernel 6.12.0:
HailoRT PCIe Driver for Linux
- Add support for linux kernel 6.12
This answer from pierrem shows there seems to be work in progress regarding ubuntu 24:
Our team is currently working to support Ubuntu 24. Not only HailoRT, but also the other components of the SW Suite will be available for Ubuntu 24 users in the near future (exact release version to be confirmed).
I wonder why it worked for others on Ubuntu 24.04 and not for me:
As you can see, the situation is a bit diffuse. Therefore, I have a few questions:
Questions:
1.) Does your changelog from hailort-driver v4.20.0 explicitly mean kernel 6.12. or up to kernel 6.12.?
2.) What should I do now?
→ 2.1) Forget Ubuntu 24 and switch to Raspberry Pi OS?
→ 2.2) Wait for your driver support?
3.) Can you please give more information about the actual status regarding Raspberry Pi 5 and Ubuntu 24?
