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. I have no LEDs installed yet,
so I cant check those.
Maybe I made a soldering error somewhere non obvious.
Yeah, sounds like the hardware has an issue.
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
