| MaZderMind | CarlFK: with 1045 it sure does work \o/ | 15:47 |
| MaZderMind | thx | 15:47 |
| MaZderMind | which in other news mean, the recent builds are broken | 15:48 |
| CarlFK[m] | MaZderMind (IRC): yay!! | 15:48 |
| CarlFK[m] | about that time the CI VM ran out of disk (git clone the repo ate 8gig or so) | 15:48 |
| CarlFK[m] | why is di suddenly deciding not to mkfs my disk?! | 15:49 |
| CarlFK[m] | lets see what this does ? d-i partman/confirm_write_new_label boolean true | 15:53 |
| CarlFK[m] | no help. | 15:58 |

| CarlFK[m] | morning | 15:58 |

| *** CarlFK has quit IRC | 16:53 | |
| mithro | CarlFK[m]: Can you test the more recent builds and report back too me? | 17:09 |
| *** FelixVi has joined #timvideos | 17:11 | |
| mithro | Hi FelixVi! | 17:13 |
| FelixVi | mithro: morning! how are things? | 17:15 |
| FelixVi | I watched a bunch of youtube clips yesterday night... I think it's interesting how you're using mitex | 17:17 |
| FelixVi | I didn't realize there's a pci bridge that's usable | 17:17 |
| FelixVi | do you know if it works with galatea (numato) boards? | 17:18 |
| mithro | No idea -- would have to ask rohitksingh if he knows | 17:18 |
| mithro | rohitksingh works for Numato | 17:18 |
| FelixVi | is he the one in colorado springs? I am wondering if one can order from there rather than india | 17:19 |
| rohitksingh | FelixVi: High! Do you mean litepcie by _florent_ ? | 17:19 |
| mithro | No - that is Tom | 17:19 |
| rohitksingh | * Hi! (oops) | 17:19 |
| FelixVi | rohitksingh: Yes, litepcie - I think galatea has gen1 x 1 doesn't it? | 17:20 |
| mithro | The galatea is a Artix-7 IIRC? | 17:20 |
| rohitksingh | litepcie will work with galatea, although we have specifially tested with litepcie... | 17:20 |
| rohitksingh | nope S6 | 17:20 |
| FelixVi | -.- so close ;) | 17:21 |
| rohitksingh | litepcie instantiates Integrated PCIe Primitive which is present on S6 | 17:21 |
| rohitksingh | should work | 17:21 |
| FelixVi | ah, 7-series all have that, right? | 17:22 |
| FelixVi | I am still on S6 because they are cheap - but I should probably switch to 7-series sometime soon | 17:22 |
| rohitksingh | S7 don't | 17:22 |
| rohitksingh | A7 have that | 17:22 |
| *** CarlFK has joined #timvideos | 17:23 | |
| *** ChanServ sets mode: +v CarlFK | 17:23 | |
| FelixVi | nereid is a bit too expensive - but that one does work with litepcie? | 17:23 |
| FelixVi | I make devices for people - and the ideal price point for the FPGA board is <$350 | 17:24 |
| CarlFK[m] | mithro (IRC): yes, but much later - packing up to go give my talk | 17:24 |
| rohitksingh | It should also work! litepcie manages TLP layer iirc, lower details are handled by PCIe primitive | 17:24 |
| FelixVi | rohitksingh: awesome, thanks! | 17:26 |
| FelixVi | rohitksingh: Can one order from colorado springs? Is that something that is planned for the future? | 17:26 |
| rohitksingh | FelixVI: I could test litepcie with both Galatea and Nereid in the office *if* I get spare time in office, which I don't generally these days :( | 17:26 |
| FelixVi | rohitksingh: I'm not hurting without it - was just looking for a good excuse to play with a galatea board | 17:27 |
| rohitksingh | FelixVi: I guess you could. Better ask from Tom. afaik, they were planning on a US warehouse, not public plan yet though | 17:27 |
| FelixVi | For practical purposes, I might use USB3 - I think mithro might have looked into that, too | 17:29 |
| rohitksingh | for USB3.0 if you are purely into HDL, I would recommend FT60x series | 17:31 |
| rohitksingh | or if you are more willing then Daisho port by _florent_ | 17:32 |
| mithro | So, I'm pretty sure Florent doesn't test with the Spartan 6 and litepcie regularly, so I wouldn't be surprised if it is borken | 17:32 |
| FelixVi | do you think FT60x is better than ex-usb FX3? Those looked pretty good to me | 17:33 |
| FelixVi | *ez-usb fx3 | 17:33 |
| rohitksingh | yes, if 1) you don't want headaches with firmware, and I'm sure you will get quite 2) if you want simple FIFO interface | 17:34 |
| rohitksingh | even limesdr guys have switched from fx3 to ft601 | 17:34 |
| rohitksingh | so does @fgpa_nugga from twitter | 17:35 |
| FelixVi | ah, that's good to know :) | 17:36 |
| FelixVi | I looked at both and the fx3 actually looked easier to use - I suppose I was wrong ;) Good thing I didn't jump the gun there | 17:36 |
| rohitksingh | Though if you want variety of USB device emulation then FX3 is the way to go | 17:38 |
| rohitksingh | FT60x are just data movers | 17:38 |
| rohitksingh | FT60x, for example, would be unable to show up as UVC webcam or others | 17:39 |
| rohitksingh | they always enumerate as FTDI USB3.0-FIFO bridge | 17:40 |
| FelixVi | oh, that's a bummer - best way would be a litex usb stack ;) | 17:41 |
| mithro | FelixVi: funny you say that | 17:41 |
| FelixVi | maybe not practical, but you should be able to do it | 17:41 |
| mithro | rohitksingh is working on a LiteX USB2.0 stack and Florent is doing the port of the daisho USB3.0 stack | 17:41 |
| FelixVi | ah, do you think it's going to be small enough? | 17:41 |
| FelixVi | well, I suppose it's easier than tcp | 17:42 |
| mithro | FelixVi: yeah | 17:42 |
| FelixVi | all I can remember is microchip's usb stack in harmony(?) that was a giant mess | 17:42 |
| FelixVi | with a HW usb stack, can you make a CDC device with higher baudrates? | 17:44 |
| FelixVi | so that pyserial works up to say 10 or 20 Mbps? | 17:44 |
| mithro | FelixVi: probably | 17:44 |
| FelixVi | that would be great for user experience | 17:45 |

| FelixVi | licensing? | 21:06 |
| mithro | FelixVi: More nobody has done it | 21:06 |
| FelixVi | because I looked at that a while back and found it hard to figure out what you need. are they really asking $5k/year? | 21:06 |
| mithro | There is a MIPI DSI project here -> https://hackaday.io/project/364-mipi-dsi-display-shieldhdmi-adapter | 21:07 |

| FelixVi | ah, so it can be done if one can figure out the interface | 21:17 |
| FelixVi | mithro: when they say mipi interface for these, is there a spec one can follow? file:///C:/Users/dell/Downloads/OmniVision_OV7251.pdf | 21:23 |

| tpb | Title: OmniVision | A leading developer of advanced digital imaging solutions. (at www.ovt.com) | 21:24 |
| FelixVi | because those would be very attractive to me (B&W, high fps, global shutter) - even though probably not so exciting for video broadcasting | 21:24 |
| FelixVi | but when I looked at the interfacing (a while back), I had no luck finding out what the interface actually looks like | 21:25 |
| mithro | The #apertus people know a lot about sensors... | 21:28 |
| mithro | bblr, going to find lunch | 21:29 |
| FelixVi | good luck ;) | 21:29 |
| mithro | FelixVi: btw I'm happy to accept a pull request with Saturn/WaxWing/etc support even if you don't have working SPI flash. | 21:34 |
| mithro | cr1901_modern: can you send a pull request for flterm that puts xmodem stuff behind a flag as soon as you can? | 21:36 |
| FelixVi | mithro: are you sure? I feel like it's almost guaranteed that we'll have to fix *something* in the target/platform | 22:02 |
| mithro | FelixVi: sure, but you can still do a lot without spiflash | 22:02 |
| FelixVi | I won't lose what we've done so far, I promise ;) | 22:03 |
| FelixVi | k, I'll submit a PR over the weekend | 22:03 |
| mithro | easier to review smaller prs | 22:08 |
| felix_ | meh, rohitksingh has left the channel. the ft602 enumerates as an uvc device; learned about that chip a few days ago | 23:16 |
| mithro | felix_: The FT602 seemed to be unobtanium last time I looked | 23:19 |
| felix_ | oh, ok; hadn't checked that. it was announced not too long ago (at least after i played a bit with the ft601), so it might still take some time to be widely available | 23:22 |

| mithro | FelixVi: Ignore codacy | 23:59 |
