| felix[m]1 | Hi y'all! I'm mucking around in your project internals (trying to figure out how things work, being new to all of this): Is there a way to toggle the configuration flags, so that the input/output is enabled automatically on startup? I can see the flags in https://github.com/timvideos/HDMI2USB-litex-firmware/blob/ab27f574f07a1cf5693a6da0da7bd93b7817c7b8/firmware/config.h (I think), but I can't figure out how to set them. | 20:15 |
| felix[m]1 | Any hints are very much appreciated. Thanks! | 20:15 |

| mithro | felix[m]1: You can change the values here -> https://github.com/timvideos/HDMI2USB-litex-firmware/blob/ab27f574f07a1cf5693a6da0da7bd93b7817c7b8/firmware/config.c#L34-L57 | 20:16 |

| mithro | felix[m]1: But they are currently hard coded into the firmware | 20:16 |
| mithro | cr1901_modern: ping? | 20:16 |
| felix[m]1 | mithro: Thanks a lot! I'll give that a shot (my C is quite rusty to say the least, but I'm, slowly understanding liteX and loving it!) | 20:17 |
| cr1901_modern | mithro: pong | 20:18 |
| felix[m]1 | Do you manually set up boards when you do recordings? | 20:18 |
| mithro | cr1901_modern: Would you be able to add support reading and writing those values from the spi flash? | 20:19 |
| cr1901_modern | mithro: Sure, but before I do that, could we go ahead and merge my previous SPI flash changes (which also currently has some conflicts)? | 20:21 |
| cr1901_modern | mithro: I need a software program which prints out my yak-stack :P | 20:21 |
| cr1901_modern | in tree format | 20:21 |
| cr1901_modern | Hmmm, I guess this feature doesn't depend on the SPI flash write code | 20:23 |
| mithro | cr1901_modern: Hrm? | 20:24 |
| cr1901_modern | mithro: I was just thinking I wanted my prev code working on the SPI flash committed before I begin working on other things related to SPI flash >> | 20:24 |
| mithro | cr1901_modern: Well the idea would be to allow writing the config values to spiflash | 20:25 |
| cr1901_modern | But now that I think about it, I'm not sure "reading out config" is all that related to "adding infrastructure to bitbang flash" | 20:25 |
| cr1901_modern | oh, so you just want me to add that functionality on top of the current PR? | 20:25 |
| mithro | cr1901_modern: I think so | 20:26 |
| cr1901_modern | Yea sure I can do that :) | 20:26 |
| mithro | cr1901_modern: You said you had litex-buildenv working with the updated litex which uses migen? I assume that wasn't updating the scripts and stuff? | 20:32 |
| felix[m]1 | You people are way awesome :-) . Thanks for your efforts, and sorry for the trouble! I'd be glad to help with this if I can (though I'm only slowly finding my way around how things work, and it's probably going to be a while until I can do something useful, but I'd be glad to help testing) | 20:32 |
| cr1901_modern | mithro: No I updated the scripts | 20:41 |
| mithro | cr1901_modern: Pull request please! :-P | 20:41 |
| cr1901_modern | mithro: Please wait 5 mins | 20:42 |

| tpb | Title: Merge in LiteX changes by cr1901 · Pull Request #27 · timvideos/litex-buildenv · GitHub (at github.com) | 21:28 |
| cr1901_modern | I tested this against the Arty platform on Linux, and also the mimasv2 platform on Windows | 21:29 |
| cr1901_modern | Next step is to do the same for HDMI2USB I presume? | 21:32 |
| cr1901_modern | mithro: Do these patches https://github.com/timvideos/conda-hdmi2usb-packages correspond to this channel? https://anaconda.org/timvideos/repo?type=conda&label=main | 21:44 |
| tpb | Title: GitHub - timvideos/conda-hdmi2usb-packages: Conda build recipes for the toolchains needed by LiteX / MiSoC firmware (at github.com) | 21:44 |
| cr1901_modern | If so I have a PR for openocd since they're glacial at accepting changes | 21:44 |
| mithro | Yeah - give me an hour to do something with your pull request | 21:45 |
| cr1901_modern | (well, two PRs, if you can live with the second patch potentially diverging/having changes requested when I submit it upstream) | 21:45 |
| mithro | yes, please do | 21:45 |
| cr1901_modern | Is the second PR acceptable w/ the caveat? (arty s7 board file) | 21:45 |
| cr1901_modern | Actually, it should be. As I recall, you cancelled your upstream PR for Arty A7. I'll just submit both. | 21:46 |
| mithro | cr1901_modern: There was already an open PR for the Arty A7 | 21:55 |
| cr1901_modern | mithro: I understand. But considering the open PR has been open SINCE June, and the devs are STILL req changes, I imagine that if I submit a PR to your conda repo it won't look the same as what gets committed to upstream. | 22:02 |
| mithro | cr1901_modern: That was amore an answer about they I closed the openocd pull request | 22:02 |
| cr1901_modern | Ahh fair | 22:02 |
| cr1901_modern | But still, they are _glacial_ at getting changes in it seems :( | 22:02 |

| * cr1901_modern is currently cleaning up all his remote repos and branches in bulk | 22:12 | |
| cr1901_modern | Good lord I have a lot of them | 22:12 |
| CarlFK[m] | felix - once we have somewhat current firmware flashed, we use the defaults | 22:14 |
| CarlFK[m] | so we manually flash, but generally they power up in the state we want them | 22:14 |
| CarlFK[m] | there are exceptions, like "we really need 1024x768, so lets do that for this one talk, and then reset back to 720p" | 22:15 |
| felix[m]1 | Ah, that makes total sense! Thanks | 22:16 |

| mithro | cr1901_modern: I reworked your pull request a little bit - just waiting for travis to confirm if things are all good | 22:30 |
| cr1901_modern | mithro: Sure, I understand. For some reason travis didn't start doing a build when I submitted my PR | 22:31 |
| mithro | cr1901_modern: Because it wasn't setup on litex-buildenv | 22:32 |
| cr1901_modern | Ahhh, looks like you squashed my commits? | 22:34 |
| mithro | cr1901_modern: I used the "merge-upstream.sh" script to get a nicer commit message | 22:34 |
| cr1901_modern | Ahhh I see, cool | 22:35 |
| cr1901_modern | git log --oneline whatever is pretty amazing | 22:35 |
| cr1901_modern | I'm using it right now to clean up literally dozens of branches | 22:35 |
| cr1901_modern | How do you know travis is building? I still don't see a marker saying it's doing a build on the PR | 22:36 |

| cr1901_modern | Bad enough you've made me a git intermediate :P | 22:40 |
| mithro | cr1901_modern: Looks like need to update the cut back vivado for your update -> https://travis-ci.org/mithro/HDMI2USB-litex-firmware | 23:33 |

| cr1901_modern | mithro: I have no idea what this means https://travis-ci.org/mithro/HDMI2USB-litex-firmware/jobs/349060784#L5805 | 23:42 |
| mithro | cr1901_modern: It means that the cut-back version of vivado we use on travis is missing something that is needed | 23:42 |
| cr1901_modern | mithro: This is unfortunately a case of "works on my machine". I don't know why updating a single path would cause Vivado to bomb like that. Especially since only LiteX should ever see the path changes | 23:45 |
| mithro | cr1901_modern: I'm guessing that migen is using a slightly different set of tcl method calls then litex was previously | 23:46 |
| cr1901_modern | mithro: I'm taking a look | 23:50 |
| mithro | cr1901_modern: I know how to fix it | 23:50 |
| cr1901_modern | mithro: Oh, then could you fix it for me :P? | 23:50 |
