| sf-slack4 | <timo.callahan> @kgugala @rwinkler I did finally see the new version; the timestamp in the html source said it was produced a minute after I pushed my commit, much earlier....so it seems like the old version had been cached somewhere between readthedocs and me? I don't know if that's even possible. | 05:43 |

| sf-slack4 | <kgugala> hi @jan.pleskac | 11:21 |
| sf-slack4 | <kgugala> I suppose CentOS 7.8 comes with quite old gcc | 11:22 |
| sf-slack4 | <kgugala> can you check which version do you have? | 11:22 |

| sf-slack4 | <kgugala> we test projectxray against gcc-6 (as the minimal version) | 11:26 |
| sf-slack4 | <kgugala> are you able to update the compiler? | 11:27 |
| sf-slack4 | <jan.pleskac> OK, I'll try to updated gcc. I just test arty as it is in the docs as sanity check. My primary focus is ECP5 now so prjtrellis... also gcc-6 used as minimal version there? | 11:33 |
| sf-slack4 | <kgugala> @daveshah can probably answer this | 11:33 |
| daveshah | It's unlikely anything much older than gcc 6 is regularly tested | 11:34 |
| sf-slack4 | <kgugala> @jan.pleskac if you want to just build and run the design on Arty you can check https://github.com/symbiflow/symbiflow-examples | 11:34 |

| sf-slack4 | <jan.pleskac> setup described in examples is failing with tar --one-top-level argument again version issue... Didn't find any info about minimal os requirements or known to work minimal versions used for testing. Such info or even better an environment test script would be helpful for new adopters. Did I miss that or doesn't exist? | 14:18 |
| sf-slack4 | <kgugala> the whole README is tested in CI in the examples repo. See the test grid in the CI configuration https://github.com/SymbiFlow/symbiflow-examples/blob/master/.travis.yml | 14:20 |

| sf-slack4 | <julian.speith> Hey everyone, sorry, this is way off topic, please delete if that's a problem. I am with the MPI for Security and Privacy in Bochum, Germany, where we have been looking into FPGA security for a while now. We are kinda trying to push towards open-source hardware recently and thus want to lay bare the security implications going along with proprietary hardware and its design flows. For that reason, we are looking | 14:57 |
| sf-slack4 | for _*specific*_ products that have FPGAs (preferably Xilinx ones) build into them and are in some way deployed in the real-world. We do know the areas in which FPGAs are used, sadly though we cannot just buy stuff until we find what we are looking for. This is especially the case since the actually interesting items (the ones with actual impact, you know...) are usually not in the range of a few hundred bucks. Also, this not | 14:57 |
| sf-slack4 | the kind of research that companies are interested in, so we're kinda hoping for people like you all to give us some pointers on where to look. Again, we are asking for _*specific*_ products, not product areas. If you do want to help or cooperate, just drop me a PM. We are happy for every little bit of information you share with us. Best, Julian | 14:57 |

| sf-slack4 | <olof.kindgren> @julian.speith Could be worth posting this the LibreCores discussion list https://lists.librecores.org/listinfo/discussion | 16:53 |
| tpb | Title: Discussion Info Page (at lists.librecores.org) | 16:53 |
| sf-slack4 | <olof.kindgren> I know products but as you implied, most of them are far more expensive | 16:54 |
| sf-slack4 | <julian.speith> I mean, if we are 100% sure that the product in question actually contains what we are looking for, funding may not be an issue. The more expensive it gets, the higher should be our level of certainty :D | 16:56 |
| sf-slack4 | <julian.speith> thanks a lot, will do so! | 16:56 |
| sf-slack4 | <julian.speith> so if you do know some and are at liberty to talk about them, I would really appreciate some details :) | 16:57 |
| mithro | Really interesting post at https://xobs.io/precursor-and-renode/ | 17:10 |

| sf-slack4 | <julian.speith> thanks! we thought about that too, we don't want to work against the community though. | 17:13 |

| sf-slack4 | <timo.callahan> @kgugala @rwinkler I think clouldflare CDN was caching the readthedocs page, which would explain why we were seeing different versions of it. | 20:44 |
