| mithro | _florent_: ping? | 14:43 |
| _florent_ | mithro: pong | 14:43 |
| mithro | _florent_: I should be asleep, but wanted to show you some stuff quickly if you have a moment | 14:44 |
| _florent_ | yes I have time | 14:44 |
| mithro | _florent_: https://github.com/enjoy-digital/litex/pull/5 | 14:46 |
| tpb | Title: WIP: Add versioning and CI support to litex by mithro · Pull Request #5 · enjoy-digital/litex · GitHub (at github.com) | 14:46 |
| _florent_ | mithro: cool thanks, I can merge that when you think it's ready | 14:49 |
| mithro | _florent_: The problem is that I didn't really find any "tests" to actually run? | 14:50 |
| _florent_ | yes we don't have test in litex for now | 14:50 |
| _florent_ | a good test can be to run the sim target | 14:50 |
| _florent_ | or generate the hdl for the others targets | 14:50 |
| mithro | _florent_: the problem is the sim target doesn't exit with success/failure in any way | 14:51 |
| mithro | _florent_: does litevideo require litedram? or just for the tests? | 14:51 |
| mithro | _florent_: basically, if you give me some commands to run which exit with non-zero when they fail, I can add it to the CI | 14:53 |
| mithro | _florent_: Here is the litevideo one which is similar -> https://github.com/enjoy-digital/litevideo/pull/4/files | 14:55 |
| tpb | Title: WIP: Add versioning and CI support to litevideo by mithro · Pull Request #4 · enjoy-digital/litevideo · GitHub (at github.com) | 14:55 |
| _florent_ | yes I have to think how we can get success/failure result from sim target | 14:55 |
| mithro | _florent_: https://travis-ci.org/mithro/litevideo | 14:55 |
| tpb | Title: Travis CI - Test and Deploy Your Code with Confidence (at travis-ci.org) | 14:55 |
| _florent_ | mithro: I just gived you collaborator access to all the repos (litex, litedram, etc...) | 14:56 |
| mithro | _florent_: yes, I just got like a bazillion emails :P | 14:57 |
| _florent_ | mithro: feel free to add CI to the repo (if it's not becoming to complex and if we are still able to do manual tests) | 14:57 |
| mithro | _florent_: How should I run the litedram tests? https://github.com/enjoy-digital/litedram/tree/master/test | 14:58 |
| tpb | Title: litedram/test at master · enjoy-digital/litedram · GitHub (at github.com) | 14:58 |
| _florent_ | make all, but I still have to add autochecks for these tests | 14:59 |
| cr1901_modern | mithro: Got the frequency counter working on base minispartan. I'm adding some code to the firmware to read out the frequency. | 14:59 |
| mithro | _florent_: okay | 15:00 |
| cr1901_modern | then I'll start adding HDMI in to the minispartan video target | 15:00 |
| mithro | cr1901_modern: for testing the frequency counter, it should be enough just to add the HDMI EDID Rom on the right pins | 15:00 |
| mithro | cr1901_modern: then the computer will be sending video, you'll just be ignoring it :P | 15:01 |
| mithro | cr1901_modern: but should be able to test if the frequency counter is working | 15:01 |
| cr1901_modern | I somehow expect my computer to BSOD when connecting a "monitor" that doesn't exist lol | 15:01 |
| _florent_ | mithro: for now the tests (in litesata/liteeth) just return the number of errors, but we can adapt that so that CI get the results | 15:01 |
| mithro | _florent_: if you do a sys.exit(number_of_errors) the CI will work | 15:02 |
| mithro | 0 == good | 15:02 |
| mithro | non-zero is failure | 15:02 |
| _florent_ | ok | 15:02 |
| _florent_ | we can add CI for one of the repo first | 15:03 |
| mithro | cr1901_modern: If you have EDID working the computer won't really know the difference | 15:03 |
| _florent_ | (litesata for example which has autochecks on all tests) | 15:03 |
| cr1901_modern | ahhh alright | 15:04 |
| _florent_ | and then add CI to all others repos | 15:04 |
| mithro | _florent_: so were are we with upgrading the opsis-soc upgrade stuff? | 15:04 |
| _florent_ | I'm still doing some work | 15:04 |
| mithro | _florent_: I have a branch prepared with the updated scripts/CI side | 15:04 |
| _florent_ | I want to clean up things around DRAM | 15:04 |
| cr1901_modern | and that makes sense now that I think about it | 15:04 |
| _florent_ | and I'm adding things on DRAM ports | 15:04 |
| _florent_ | I need to test that on board | 15:05 |
| mithro | cr1901_modern: obviously I'd love to see working HDMI in and HDMI out working on the miniSpartan6+ :) | 15:05 |
| _florent_ | then I'll be able to get video in/out working | 15:05 |
| cr1901_modern | mithro: the best I could do with the tools I have is frame capture | 15:05 |
| cr1901_modern | read the image into SDRAM, then flush to SD card | 15:06 |
| cr1901_modern | then on the PC side I could convert the raw image to PNG and you have a very complex screen capture program :D | 15:07 |
| cr1901_modern | _florent_: You mentioned you might've solved the bandwidth problems with the minispartan by using a particular HDMI encoding? | 15:09 |
| *** CarlFK has quit IRC | 15:09 | |
| mithro | The minispartan should have enough bandwidth for 640*480 with any problems | 15:11 |
| mithro | So, start with that :-) | 15:12 |
| cr1901_modern | mithro: Sadly, for any of my intents and purposes that's more than enough lmao. An interesting use case for something like minispartan would be a CRT shader for RGB output from old game consoles | 15:13 |
| mithro | cr1901_modern: well, what's stopping you? :-P | 15:15 |
| cr1901_modern | mithro: I don't have the correct cables for RGB output from my SNES/ | 15:16 |
| cr1901_modern | Genesis (if the latter even supports it) | 15:16 |
| cr1901_modern | mithro: Point blank, I can think of low-resolution use cases for the minispartan beyond a development board for HDMI2USB. Maybe there can be an "applications" tutorial in the future. | 15:17 |
| cr1901_modern | #ifdef XILINX_SPARTAN6_WORKS_AMAZINGLY_WELL ... sarcasm? | 15:28 |
