Hi,
Yosys 0.9 (git sha1 1979e0b)
That is from 2019 ... you might need something more current :D
make sure that
your nextpnr is built with the python bindings enabled
How to do that? I usually do:
Mmm, since it found Python, I'm guessing it was built with them.
Do you see the
"new full-speed usb device" detected and then it fails
to enumerate, or do you see nothing at all ?
Nothing at all, "dmesg" is completely empty after several rounds of
plug in and/or reset.
Ok, then I'd check the connections from the fpga to the USB connector
including the connector itself, and also the 1.5k resistor, the two
inline resistors and the ESD protection IC.
If you post a picture of that area, I can also check if I see something "off".
BTW, if you use IRC, the #osmocom on libra might be easier for that
kind of debug.
Cheers,
Sylvain
