| 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. | 18:33 |

| 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 | 19:03 |
| 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! | 19:07 |
| 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? | 19:55 |
| *** enriq has joined #symbiflow | 19:56 | |
| litghost | textx is listed in the requirements.txt here : https://github.com/SymbiFlow/prjuray/blob/master/requirements.txt#L15 | 19:56 |
| *** enriq has quit IRC | 19:56 | |
| tpb | Title: prjuray/requirements.txt at master · SymbiFlow/prjuray · GitHub (at github.com) | 19:56 |
| 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) | 19:57 |
| 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 | 19:58 |
| 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) | 20:02 |
| litghost | unrznbl: Good catch, feel free to actually open the PR | 20:03 |
| 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. | 20:04 |
| *** enriq has joined #symbiflow | 20:05 | |
| 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... | 20:09 |
| 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 | 20:10 |
| 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? | 20:11 |
| unrznbl[m] | ok. Cleaned up that PR, haven't done DCOs before really. ;) | 20:23 |
| litghost | No problem! Thanks for the fix | 20:23 |
| 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 | 20:31 |
| 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. | 20:32 |
| 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 | 20:36 |
| unrznbl[m] | now I just need to figure out a nice hack to program the thing via SPI 👍️ | 20:52 |
