| sf-slack2 | <acomodi> ric96: This may be an issue with the Linux images. I am currently using this ones https://we.tl/t-e8Uq147RAD (The problem is that I have generated them quite a while ago and I do not remember their origin) | 08:59 |
| ric96 | sf-slack2: any idea on the commit id? I can build | 09:05 |
| sf-slack2 | <acomodi> ric96: I was able to regenerate working Linux images for the litex-linux example from https://github.com/timvideos/litex-buildenv (commit 17e230ec8af0838060d12e3d810a448825d13fd2) and following the Linux wiki (https://github.com/timvideos/litex-buildenv/wiki/Linux) | 09:38 |

| sf-slack2 | <timo.callahan> Hmm, in my 100T work, I must have missed something...or, I copied something from 50T when I should have copied from 200T. I get this error: `Type: Architecture file File: /tmp/really-really-really-really-really-really-really-really-really-really-really-really-really-long-path/conda/conda-bld/vtr_1589474563511/work/vpr/src/util/vpr_utils.cpp Line: 2318 Message: *Unable to find port CLBLM_L_COUT (on block | 15:41 |

| andrewb1999 | acomodi: Building the pynqz1 buttons test using the branch you sent yesterday is crashing for me | 17:15 |

| andrewb1999 | When building channels.db | 17:16 |
| andrewb1999 | Any ideas on what's going wrong here? | 17:16 |
| sf-slack2 | <acomodi> andrewb1999: yes, I think that the solution would be to decouple the two architecture definitions in two separate root dirs (zynq010 and zynq020). This because the generic channels.db is shared both for the z010 and z020, hence, when building the z020, the errors you see are produced | 17:18 |
| sf-slack2 | <acomodi> It should be similar to what has been done for artix7 and artix_200t | 17:18 |
| andrewb1999 | acomodi: Okay I will look into doing that | 17:19 |

| sf-slack2 | <timo.callahan> Q: Does PrjXray support "BUFR"? | 21:04 |
| litghost | I believe so | 21:06 |
| litghost | I added fuzzers for it | 21:06 |
| litghost | I don't know if symbiflow-arch-defs integrated it | 21:06 |
| litghost | Now that acomodi's heterogeneous VPR feature is landed, in theory you should be able to just ask the tile import script to import it | 21:07 |
| sf-slack2 | <timo.callahan> I tried using it in the counter test, and it complained "Failed to find matching architecture model for 'BUFR'". I wondered if I need to use arty-full instead of arty-swbut. But I'll see if I can do as you describe, add it in the right place. | 21:09 |
| sf-slack2 | <timo.callahan> I had previously tried BUFG, which doesn't work with arty-swbut but does work with arty-full in my observation. | 21:10 |
| *** OmniMancer has joined #symbiflow | 21:17 | |
| litghost | arty-swbut is an ROI based graph, which has no clock elements | 21:30 |
| litghost | arty-full is the full graph, which supports clock elements | 21:30 |
| litghost | To be clear BUFG and BUFR are different black boxes | 21:30 |
| litghost | BUFG support is well tested | 21:30 |
| litghost | BUFR support is not | 21:31 |
