Just updated my raspberry pi’s os version today and now my raspberry pi AI hat+ is no longer recognised when using
“hailortcli fw-control identify”
Instead getting error:
“[HailoRT] [error] Can’t find hailort driver class. Can happen if the driver is not installed, if the kernel was updated or on some driver failure (then read driver dmesg log)
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_DRIVER_NOT_INSTALLED(64) - Failed listing hailo devices
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_DRIVER_NOT_INSTALLED(64)
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_DRIVER_NOT_INSTALLED(64)
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_DRIVER_NOT_INSTALLED(64)
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_DRIVER_NOT_INSTALLED(64)
[HailoRT CLI] [error] CHECK_SUCCESS failed with status=HAILO_DRIVER_NOT_INSTALLED(64)”

Any suggestions on a potentail fix to this issue?
Many thanks!

Welcome to the Hailo Community!

The first thing to check is whether the Hailo-8 is detected by the system using the lspci command. This works even without the HailoRT PCIe driver installed.

When you can see the Hailo-8 check whether there are any updates available and install them.

Turned out the PCIE cable just wasn’t installed correctly!

i have the same issue. The AI hat+ connection seems to be fine. But i am getting the exact error. Reinstalled the os multiple times. How to solve this?
