Problems running the hailo raspi5 examples

General
1

Hi,

My Setup:
Hailo8l based AI-HAT+
Raspi 5, 4 GB RAM
Raspberry Pi OS 64 bit, up to date (06.05.25)

Two months ago I installed the hailo rpi5 examples on my raspi and I could execute all the “hailo-rpi5-examples” without problems. Now I have the problem that only the detection_simple.py example is running sometimes.
All other examples will start (and have some output), but the preview video does not appear and the inferencing does not start.

Journalctl -f shows me the following lines which may cause the problem:

May 06 10:31:03 raspikatze kernel: hailo: get_user_pages failed with -4
May 06 10:31:03 raspikatze kernel: hailo 0001:01:00.0: failed to set sg list for user buffer -4
May 06 10:31:03 raspikatze kernel: hailo 0001:01:00.0: failed map buffer 7fff20428000

If the detection_simple.py examples runs successfully I will not see these lines in the kernel log.
I made a lot of testing on my OS installation and so I took a brand new SD card and installed a fresh copy of the latest Raspberry Pi OS 64 bit. Then:

sudo apt update
sudo apt full-upgrade
sudo apt install hailo-all
reboot
git clone GitHub - hailo-ai/hailo-rpi5-examples
./install.sh
source setup_env.sh
python basic_pipelines/detection.py

Unfortunately same behavior as before. Nothing else was installed and so it looks like some kind of driver problem.

hailortcli fw-control identify:

sudo rpi-eeprom-update

RELEASE: default (/usr/lib/firmware/raspberrypi/bootloader-2712/default)

As this is so easy to reproduce it may affect not only me.

Any suggestions?

I experienced the same issue after the latest update. I’m not entirely sure what the exact cause is, but I suspect the new kernel version 6.12.25 might be to blame. I restored a backup image with version 6.12.20, and everything is working fine now.

Hmm, this looks like a real show stopper on the Raspi.
But I’m lucky, I only want to realize a hobby project, so I’ll wait for a solution before going on testing…
