| 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?) | 00:30 |
|---|---|---|
| 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 | 00:31 |

| mithro | shuffle2: SymbiFlow doesn't attempt to provide an IDE or build system at the moment | 06:19 |
| 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) | 06:24 |

| 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? | 06:58 |
| sf-slack | <acomodi> IIRC it needs the correct baud rate set | 07:07 |
| sf-slack | <acomodi> I think it should work fine with the following: `picocom --baud 460800 /dev/ttyUSBX` | 07:09 |

| 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". | 15:52 |
| sf-slack | <acomodi> @timo.callahan Great! Yeah picocom and picosoc are actually unrelated | 15:55 |
