10:22 <sb0> DMA simply seems to have become very slow to start... needs ~400us before the dma start command and the first event

10:22 <sb0> otherwise it still works as intended. weird.

10:23 <sb0> wondering if this is really because of SED or if master has also become affected somehow

10:23 <sb0> of course, there had to be at least one insufferable bug in this SED project ...

23:22 <GitHub99> [smoltcp] little-dude commented on issue #44: Sorry for polluting the discussion, but I'm interested in following (and potentially helping) your redox integration @batonius, but I can't find where you're pushing the code in your github feed. Is this work private for the moment? I tried, long ago to use smoltcp in redox but I gave up half-way through. https://git.io/v5dV8

23:28 <Arpit> It seems my message is missed. So posting it again.

23:28 <Arpit> >> maybe the best way would be to implement a differential tristate <<

23:28 <Arpit> I have went code related to SPI (in artiq) and tri state (in migen). But I couldn't figure out lots of things in few hours of code browsing.

23:28 <Arpit> Though I read artiq documentation and migen documentation (present in the file "fhdl.rst"), many things are not yet clear to me. One of the things is, if gateware/spi.py calls cs_n_t.o.eq in comb, how does that affect voltage on pin pads.cs_n (target pin)?

23:28 <Arpit> What is the path in source code that links function call cs_n_t.o.eq to voltage on pin pads.cs_n (target pin)?

23:29 <Arpit> Also, if you could give an outline on how to implement a differential tristate, it'd help.
