Hey @saverio.taliani,
Welcome to the Hailo Community!
I see that your device is currently running an older version, but you can upgrade to version 4.18 to take advantage of the latest updates in both DFC and HailoRT (versions 3.28 and 4.18, respectively). You can find more information and detailed instructions in this thread: Update Firmware on Hailo-8. The DFC has received significant improvements since version 3.25, which was released about a year ago.
Then please re-run the compilation of the model and check if you have the same problem !
Regards
