18:03 <lsneff> Does nmigen support the de0-nano? It seems like nmigen-boards has a few adjacent boards, but not that particular one.

18:11 <miek> lsneff: there's an open PR for it https://github.com/nmigen/nmigen-boards/pull/113

18:11 <lsneff> Does it work?

18:12 <miek> i don't know

19:02 <korken89> anuejn: Are you around? I gave your datastreamer example app a try and se sustained 185-186 MB/s with the FT600 - very nice! One thing I tried though, if I do not send continuous data it seems to fail. E.g. I tested to fill the fifo from a 25 MHz domain. Is this something you have come across?

19:04 <anuejn> korken89: what does fail?

19:04 <anuejn> (in which way)

19:04 <anuejn> is the data you receive not continous?

19:04 <anuejn> what does your gateware look like?

19:04 <korken89> I get the error which says got only "xx bytes of 32768"

19:05 <anuejn> ah i see

19:05 <korken89> I'll push the test I'm running if you are interested in having a look

19:05 <anuejn> maybe it is best to come to #apertus because that is not too nmigen related

19:06 <anuejn> but yes, i came across that mode of failure

19:06 <korken89> Sure, I'll drop in!

20:19 <d1b2> <gramunculus> sorry to butt in, but could you link me to what you guys are talking about? I'm planning to try a project streaming over ft600, sounds useful

20:24 <gramunculus> thanks!

20:24 <anuejn> we were talking about https://github.com/apertus-open-source-cinema/ft60x-rs
