Hi @KlausK ,
Okkay i have testing it on raspberry pi 64 bit full os and it detect the hailo devices and able to run the .hef model, the problem is when i try to install this on lite version using:
apt install hailo-all
its able to install the drivers and other dependencies but the problem is there is a firmware error you can refer to this post how i manage to solve it.
You can refer to the problem, and you can recreate it by fresh lite os installation and try to install the hailo libraries.
