Hailo-8 Detected on PCIe but hailortcli fw-control identify Returns Nothing

General
1

Hello Hailo Community,

I’m using a Raspberry Pi 5 with the Hailo-8 AI Processor on the PCIe bus. The system detects the device correctly, but I’m unable to identify the firmware with HailoRT.

System Info & Observations:

sai@raspberrypi:~ $ lspci
0001:00:00.0 PCI bridge: Broadcom Inc. and subsidiaries BCM2712 PCIe Bridge (rev 21)
0001:01:00.0 Co-processor: Hailo Technologies Ltd. Hailo-8 AI Processor (rev 01)
0002:00:00.0 PCI bridge: Broadcom Inc. and subsidiaries BCM2712 PCIe Bridge (rev 21)
0002:01:00.0 Ethernet controller: Raspberry Pi Ltd RP1 PCIe 2.0 South Bridge

fwd@raspberrypi:~ $ hailortcli fw-control identify

no output

Installed Hailo packages:

ii hailo-all 4.20.0
ii hailo-tappas-core 3.31.0+1-1
ii hailofw 4.20.0-1
ii hailort 4.20.0
ii python3-hailort 4.20.0-1
ii rpicam-apps-hailo-postprocess 1.9.0-1~bpo12+1

OS & Kernel:
Operating System: Debian GNU/Linux 12 (Bookworm)
Kernel: Linux 6.12.47+rpt-rpi-2712
Architecture: arm64

What I’ve Checked So Far:

  • PCIe device is detected (lspci)

  • Hailo firmware package is installed

  • Tried hailortcli fw-control reset → still nothing

Questions:

  1. How can I verify that the Hailo PCIe driver is correctly loaded?

  2. How do I confirm the firmware is being correctly recognized?

  3. Any troubleshooting steps to get hailortcli fw-control identify to respond?

You can use standard Linux tools.

Display detailed information about the Hailo PCIe kernel module, such as version, author, license, and supported parameters.

modinfo hailo_pci

Check if the Hailo PCIe kernel module is currently loaded.

lsmod | grep hailo

Show kernel log messages related to the Hailo driver.

dmesg | grep hailo

This does not look good and explains your issue. Another user reported that this happened to him on the Lite OS version. Did you use that?

There are a few other posts with that message. You can find them with the Search function in the upper right corner

we are using Linux 6.12.47+rpt-rpi-2712 (Bookworm) OS FUll OS only.

Can you make sure, you have the expected firmware file either as a real file or as a symlink to the needed version.

I’m already running 4.23, so things look a little bit different, but you get he idea;-)
