07:24 <_florent_> geertu: nice! Thanks for sharing, if you identify limitations while playing with featherwing extensions we could try to improve this.

08:43 <geertu> _florent_: sure, will do

09:47 <zyp> _florent_, possibly related: I'd like a way to do something like add_extension() that adds connectors

09:48 <zyp> consider e.g. the butterstick with syzygy connectors, and then you plug a syzygy to pmod adapter board into one

09:54 <geertu> zyp: That's a bit different, as unlike Featherwings, there is no standard w.r.t. signals on syzygy connectors (or is there?)

09:59 <zyp> there's some, but those are more fpga-oriented like clock capability and differential pair polarity/capability

10:00 <zyp> but I was thinking more in the sense of boards attached to boards so you get several levels of pinout mappings

13:19 <Melkhior> @somlo Trying to stress-test the sdcard in buildroot (to see if I can reproduce the issue I have with Yocto), so far it's doing good; I've created a buildroot with more packages and cross-compiled binutils/gcc in it, then rebuilt a small numerical code in it and ran it with no issue.

13:19 <Melkhior> Now I'm pushing the sdcard a bit more: added a 128 MiB swapfile, and started the numerical code with a test case requiring ~330 MiB (the board has 256 MiB) under 'screen'.

13:19 <Melkhior> So far it hasn't crashed, step 1 is correct (roughly 40x slower than from memory), and I can disconnect from screen, run 'top' for a while, and reconnect screen ; it's very, very slow - but it doesn't crash:-)

13:19 <Melkhior> The only other device I use is the serial port for my console, no idea why Yocto is completely unreliable with the exact same kernel/dtb

13:19 <Melkhior> Maybe I should try disabling the [currently not working in Linux] Ethernet in the gateware - Yocto probably try to use it when buildroot just ignore it...

16:29 <dormito> For a Litex project: If I have two module wrappers, is there any guides/turials that cover basic things like routing an output from one module ot the input of another?

19:58 <somlo> Melkhior: interesting point -- I tried building the bitstream without ethernet support. I get the same hard lock-up when I try using multi-block sdcard write commands from linux

19:58 <somlo> at least the problem's symptoms don't change with what should be unrelated gateware being present or not...

23:41 <thorns> hi folks - trying to extend a target for the first time, and I have a total noob question - I can't figure out how radiona_ulx3s.py (the target) is connected to radiona_ulx3s.py (the platform)?

23:41 <thorns> I see I import ulx3s from litex_boards.platforms but in the ulx3s.py platform I see no mention of that namespace or whatever it is...

23:43 <thorns> I see that I create ulx3s.Platform, which makes sense, but again I don't know where that namespace comes from

23:45 <thorns> nm I see there's some magic in litex_boards/__init__.py I think this is the connector
