Re: icE1USB gateware

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
