Hailo 8, seems to be fine, but any of the basic examples doesn't work

General

I’ve installed a brand new Hailo 8 in a Raspberry Pi 5 (8GB). After software installation I made these all checks:

  1. hailortcli scan >>>>
    Hailo Devices:
    [-] Device: 0001:01:00.0
  2. hailortcli fw-control identify >>>>
    Executing on device: 0001:01:00.0
    Identifying board
    Control Protocol Version: 2
    Firmware Version: 4.20.0 (release,app,extended context switch buffer)
    Logger Version: 0
    Board Name: Hailo-8
    Device Architecture: HAILO8
    Serial Number: <N/A>
    Part Number: <N/A>
    Product Name: <N/A>
  3. lspci | grep Co-processor >>>>
    0001:01:00.0 Co-processor: Hailo Technologies Ltd. Hailo-8 AI Processor (rev 01)
  4. Finally, looking for errors. I run this command:dmesg | grep hailo

There you can see those finally tasks that “fail”
Please, help me to see what’s wrong with my Hailo 8!
Thanks in advance.

Hi @jhidalgo,

Welcome to the Hailo Community!

Could you check what kernel version you’re running on your Raspberry Pi? Just run this command:

uname -r

If you’re on anything higher than 6.12.20, you’ll need to downgrade it. There’s a compatibility issue with newer kernels. I’ve put together a guide with the steps you’ll need to follow here: Raspberry Pi Kernel Compatibility Issue - Temporary Fix

Let me know if you run into any issues with the downgrade process!

Hi omria, yesterday I was able to downgrade, following @Kletternaut ([BUG] Deadlock in hailo_pci driver on Raspberry Pi 5 (Kernel 6.12.x) - #10 by Kletternaut).
And now my Kernel version is:
$ uname -r
6.6.77-v8-16k+
And everything is working now.
Thanks for your support
