18:33 <sf-slack> <jonathan.brent.nelson> Question about running Project URAY. What setup do you have to do in order to actually get it to run? I know that project XRAY required a lot of setup, so I assume my lack of setup I've done is why URAY currently will not run for me.

19:03 <litghost> Everything that the CI does is in https://github.com/SymbiFlow/prjuray/blob/master/.github/kokoro/db-full.sh

19:03 <tpb> Title: prjuray/db-full.sh at master · SymbiFlow/prjuray · GitHub (at github.com)

19:03 <litghost> Pretty much the only thing you need to provide is a working Vivado 2019.2 instance

19:07 <unrznbl[m]> I am interested in getting an FPGA to run a core for 6809, 8051 and/or z80 to learn more about low-level forth, and maybe in the process learn a bit about designing a core, maybe even poking at cell baseband/dsp sorts of things eventually. I have an ice40 cheap board (UPDuino 1.0 from gnarly) and am working through the "Getting Started" section of your project. Thanks!

19:55 <sf-slack> <jonathan.brent.nelson> Project URAY still does not work for me, and claims that it cannot import textx. Is there anything you have to do to get that to show up?

19:56 <litghost> textx is listed in the requirements.txt here : https://github.com/SymbiFlow/prjuray/blob/master/requirements.txt#L15

19:56 <tpb> Title: prjuray/requirements.txt at master · SymbiFlow/prjuray · GitHub (at github.com)

19:57 <litghost> And the "env" target here: https://github.com/SymbiFlow/prjuray/blob/master/Makefile#L22-L40 installs the dependencies from there

19:57 <tpb> Title: prjuray/Makefile at master · SymbiFlow/prjuray · GitHub (at github.com)

19:58 <litghost> And when the uray settings are sourced, it enters the venv here: https://github.com/SymbiFlow/prjuray/blob/master/utils/environment.sh#L25-L27

19:58 <litghost> So you are missing a step somewhere

20:02 <unrznbl[m]> a very tiny PR, got a top.bit file at the end, so that's good! (sadly I have not that device to use, will look at ice40 examples now)

20:02 <tpb> Title: Comparing SymbiFlow:master...craigcomstock:patch-1 · SymbiFlow/symbiflow-arch-defs · GitHub (at github.com)

20:03 <litghost> unrznbl: Good catch, feel free to actually open the PR

20:04 <unrznbl[m]> of course. Done.

20:04 <litghost> unrznbl: If you are using ice40, I recommend nextpnr as the ice40 support in symbiflow-arch-defs is very incomplete and untested.

20:04 <unrznbl[m]> ok. will take a look.

20:09 <unrznbl[m]> where would I start for my UPDuino 1.0? ~/src/symbiflow-arch-defs/build/ice40/tests/blink$ grep blink_ Makefile | grep bit

20:09 <unrznbl[m]> shows me a bunch of different devices: icestick, hx8k, icevision, tinyfpga...

20:10 <unrznbl[m]> from the board info page at http://www.gnarlygrey.com/ it says: Lattice UltraPlus FPGA

20:10 <unrznbl[m]> 5.3K LUTs, 1Mb SPRAM, 120Kb DPRAM, 8 Multipliers

20:11 <litghost> https://github.com/yosyshq/nextpnr#getting-started

20:11 <tpb> Title: GitHub - YosysHQ/nextpnr: nextpnr portable FPGA place and route tool (at github.com)

20:11 <unrznbl[m]> ah, so follow that instead of doing the same thing as the getting started example?

20:23 <unrznbl[m]> ok. Cleaned up that PR, haven't done DCOs before really. ;)

20:23 <litghost> No problem! Thanks for the fix

20:31 <unrznbl[m]> litghost: that nextpnr link you sent, that has nothing to do (directly) with symbiflow-arch-defs then? As in there is no "make something" I should do in there, but rather checkout https://github.com/yosyshq/nextpnr and go from there?

20:31 <tpb> Title: GitHub - YosysHQ/nextpnr: nextpnr portable FPGA place and route tool (at github.com)

20:31 <litghost> Yes

20:32 <litghost> Different project, similiar goals, some overlap

20:32 <unrznbl[m]> right, symbiflow is like an umbrella project somewhat then?

20:32 <unrznbl[m]> thanks, will try it out.

20:36 <litghost> More or less. symbiflow-arch-defs is just one repo under the symbiflow moniker. There is other work, like system verilog support, or the bitstream documentation, etc

20:52 <unrznbl[m]> now I just need to figure out a nice hack to program the thing via SPI 👍️
