| mithro | afternoon everyone! | 13:17 |
|---|---|---|
| CarlFK | hey mithro | 13:18 |
| mithro | CarlFK: I'm at DebConf15 now | 13:18 |
| CarlFK | mithro: what are you calling your hdmi2usb board? Opt...something | 13:19 |
| mithro | Numato Opsis | 13:19 |
| mithro | CarlFK: have you checked out the new website? | 13:20 |
| CarlFK | no | 13:20 |
| CarlFK | http://hdmi2usb.tv/home/ | 13:21 |
| CarlFK | neat | 13:21 |
| tpb | Title: HDMI2USB - Open hardware for conference, meeting and user group HD recording! (at hdmi2usb.tv) | 13:21 |
| CarlFK | the top arrow is broken :p | 13:21 |
| mithro | CarlFK: yeah I know - still needs a lot of love | 13:21 |
| CarlFK | have you used it for a real talk yet? | 13:21 |
| mithro | CarlFK: not yet, but I'm working on that | 13:27 |
| mithro | CarlFK: The new firmware doesn't exhibit the EDID problem that the old one did | 13:28 |
| CarlFK | cool | 13:29 |
| mithro | CarlFK: It also as the potential for Ethernet streaming | 13:30 |
| CarlFK | I am at a friends house in NJ (state near NYC where PyGotham was ) fly home tonight | 13:30 |
| mithro | CarlFK: I just need to figure out a small bug in the FX2 firmware to get USB streaming working when you don't use a JTAG programmer | 13:30 |
| CarlFK | mithro: is the "potential for Ethernet streaming" different than the Atlys board? | 13:31 |
| mithro | CarlFK: as in, using the gigabit ethernet instead of the USB to receive the video (on both the Atlys and the Opsis boards) | 13:31 |
| *** _florent_ has joined #timvideos | 13:41 | |
| mithro | Hey _florent_ ! | 13:50 |
| _florent_ | hi mithro | 13:52 |
| mithro | I'm currently away from keys, but should be back in 20-30 minutes | 13:53 |
| _florent_ | ah OK, I should be there | 13:54 |
| _florent_ | I hope you found people interested by hdmi2usb at cccamp :) | 13:55 |
| mithro | Yes, quite a few. | 13:57 |
| *** _florent_ has quit IRC | 14:02 | |
| *** _florent_ has joined #timvideos | 14:14 | |
| mithro | _florent_: back now | 14:51 |
| _florent_ | ok | 14:52 |
| _florent_ | so have you been able to do more tests with the new firmware? | 14:53 |
| mithro | _florent_: Did you want to discuss stuff now? | 14:53 |
| _florent_ | yes I have time now | 14:53 |
| mithro | _florent_: No, I didn't really get much chance to test stuff at the camp | 14:54 |
| mithro | _florent_: most people where interested just in looking at the hardware rather than get a demo of the stuff | 14:54 |
| _florent_ | and for now the demo stuff is not very impressive on the opsis board :) | 14:55 |
| mithro | _florent_: I didn't get any further with debugging the FX2 firmware either | 14:55 |
| _florent_ | since the FPGA for this part is simple, I think this is a software issue in the FX2 | 14:57 |
| mithro | _florent_: Yeah, I'm pretty sure it is as simple as something not getting reset/setup correctly | 14:57 |
| _florent_ | yes | 14:57 |
| _florent_ | but it strange it worked with the old FPGA firmware since the FX2 firmware has not been modified | 14:58 |
| mithro | _florent_: yes, it is a bit strange | 14:58 |
| _florent_ | I should try to use libfpgalink and try to see if I'm able to fix that if you don't have time for that | 15:00 |
| *** techman83 has quit IRC | 15:00 | |
| mithro | _florent_: I think I would prefer you to spend any time on getting the quad DDR stuff working | 15:01 |
| _florent_ | ok | 15:01 |
| *** techman83 has joined #timvideos | 15:02 | |
| *** ChanServ sets mode: +v techman83 | 15:02 | |
| mithro | _florent_: I think I would prefer you to spend any time on getting the quad DDR stuff working | 15:02 |
| _florent_ | I'm going to add the second video in port and second video out port to the design | 15:04 |
| _florent_ | manage that in the firmware | 15:05 |
| *** mithro has quit IRC | 15:05 | |
| _florent_ | and then work on the quarter rate DDR controller | 15:05 |
| *** mithro has joined #timvideos | 15:10 | |
| *** ChanServ sets mode: +o mithro | 15:10 | |
| mithro | gah network problems | 15:11 |
| mithro | _florent_: Does the Atlys have enough bandwidth with the downsampling to do that? | 15:11 |
| _florent_ | it should be fine with a sys_clk of 85Mhz | 15:13 |
| mithro | _florent_: okay | 15:15 |
| _florent_ | otherwise, for litescope, the best is probably to create (and keep) a self.debug = (signal1, signal2, ... signaln) structure in the core, and use it from the top | 15:15 |
| _florent_ | but keeping litescope permanently is probably going to be difficult since I'm not sure since it use blockrams and sometimes generate timing issues | 15:19 |
| mithro | _florent_: okay | 15:20 |
| mithro | _florent_: so I got as far as getting the litescope inside the usb-streamer to compile | 15:21 |
| _florent_ | ok, but you will probably have use another uart for litescope (or desactivate the uart of the lm32) | 15:22 |
| mithro | _florent_: can I use the ethernet for it instead? | 15:23 |
| mithro | s/can/should/ | 15:24 |
| _florent_ | yes you can | 15:24 |
| _florent_ | you can create your design on top of EtherboneSoC for that | 15:28 |
