00:30 <shuffle2> i'm currently using lattice diamond and want to compare it with the foss flow. it seems like symbiflow is a container project encapsulating the required other projects (yosys+nextpnr+prjtrellis + others?)

00:31 <shuffle2> however i can't really find any details about how to "replace diamond with foss"..it's more like "here's a bunch of spaghetti, string it together yourself", am i missing something

04:44 <shuffle2> ah nice

05:03 <shuffle2> soon it will be full circle :p https://twitter.com/oe1cxw/status/929450962548285440

05:05 <xobs> I'm more amazed they got a response from Xilinx on Twitter.

05:07 <shuffle2> haha hadn't noticed that

06:19 <mithro> shuffle2: SymbiFlow doesn't attempt to provide an IDE or build system at the moment

06:24 <shuffle2> it's a bit confusing because the symbiflow website has this quite nice "get started" button...which doesn't really help you to get started *using* the tools imo ;p (developing them, maybe)

06:33 <shuffle2> nice :)

06:58 <sf-slack> <timo.callahan> @kgugala, with the picosoc_demo, is it supposed to do anything when actually loaded on the basys 3 board? Or no, since we haven't loaded any software to run on the gateware? I see the 16 LEDs cycling, and when I connect to it using lxterm, it spews out jibberish it seems. And when I send characters _to_ the board via lxterm, the LED cycling stops momentarily. Am I doing something wrong?

07:07 <sf-slack> <acomodi> IIRC it needs the correct baud rate set

07:09 <sf-slack> <acomodi> I think it should work fine with the following: `picocom --baud 460800 /dev/ttyUSBX`

07:40 <shuffle2> if nextpnr failed to meet timing, prints "ERROR: failed to route...", then appears to hang...is it doing $stuff, or actually hanging

07:40 <shuffle2> it's just sitting there consuming 1 hw thread

15:52 <sf-slack> <timo.callahan> @acomodi -- thanks! I tried using "--speed 460800" with lxterm, and it helped a bit -- I saw the "Press ENTER to continue..." lines...but pressing enter didn't do anything. Trying different speeds didn't help. So I looked for picocom in the picorv32 github with no luck...until I finally just checked if I could find "picocom" as an installable Ubuntu package...and there it was! So "picocom" is not related

15:52 <sf-slack> to "picoSoc" ? Anyway it now WORKS using picocom. After pressing enter, I see option [9] "Run simplistic benchmark".

15:55 <sf-slack> <acomodi> @timo.callahan Great! Yeah picocom and picosoc are actually unrelated

16:45 <mithro> We should look at adding an `.editorconfig` to the SymbiFlow repositories

16:49 <_whitenotifier-9> [ideas] mithro opened issue #50: Add an .editorconfig file to all SymbiFlow repositories - https://git.io/JfOGn

17:00 <mithro> hackerfoo: Hadn't heard of it until I saw it being used in yosys's repo

17:01 <mithro> Yosys isn't known for using the latest and greatest stuff -- So I think that is potentially a good sign that it's been around a while?

17:05 <hackerfoo> I'll see if I can run `c-guess` in Emacs use that to generate an .editorconfig

17:14 <hackerfoo> It doesn't look like there's an easy way to do this. This can infer an .editorconfig, but it could be Javascript only: https://github.com/jedmao/eclint
