Hi Csaba, > The build process is error free until that point I copied into my previous > mail.
Mmm, make sure that your nextpnr is built with the python bindings enabled. Also which yosys version are you using ? I tried this morning with the daily build / binary package from oss-cad-suite and it built fine. You can also send me your `.json` file out of yosys so I can narrow down the issue to the yosys or nextpnr side. > But no USB enumeration.

Do you see the "new full-speed usb device" detected and then it fails to enumerate, or do you see nothing at all ? Cheers, Sylvain
