Can’t find chipid - 4ZeroBox

on registering a 4ZeroBox I get “Can’t find chipid”.
I thing the driver is working in the right way: trying to get device info in Zerynth Studio, I get all the expected information, comprised also the serial port.

The registration process seem OK:

If I open the console I see continusly a boot sequence:

What’s wrong?

Strange thing: “” in the boot sequenced.

I tried to erase flash without results.

Thank you in advance
