mithrocr1901_modern: How is that spi stuff going?00:25
cr1901_modernmithro: Has not changed since "whenever I last talked to you". And won't be able to work on it until tomorrow night at earliest due to prior engagement.00:26
CarlFK[m]mithro (IRC): do you know where the issue is for the serial connection blocking the video stream?00:33
CarlFK[m]I want to compare error messages.00:34

CarlFK[m]thanks - didnt know you could search across repos like that00:58
mithroCarlFK[m]: It's a bit of a hidden thing01:00
mithroCarlFK[m]: can actually search across all of github :-P01:00
CarlFK[m]mithro (IRC): what do you call it when you see this in dmesg:01:06

CarlFK[m]thats right01:06
CarlFK[m]that may have happened when I un/plugged the usb cable01:07

CarlFK[m]hi Max01:26
mithrojea: I'm pretty sure there is an issue with that pull request01:27
mithrojea: The output is image.bin?01:27
jeamithro: I'll check01:28
mithrojea: I'm building now locally to test myself01:28
mithroGuess I'm wrong...01:38
mithroFlash image: build/opsis_video_lm32/flash.bin01:38
mithroIt's a bit weird that "make image" creates a flash.bin....01:38
jeaso flash.bin is the right one?01:38
jeaI remember seeing an image.bin previously, but maybe that was the prebuilt firmware?01:39
jeadeeprave just ran it, and it worked with flash.bin01:39
jeaneeded to do a reset-opsis first because it must have been in the wrong mode01:40
mithromerged it...01:43
mithroI'm learning about waf and if we should be using it for HDMI2USB :-P01:44
cr1901_modernmithro: So, my strong opinions aside about waf, it prob is a good fit if you can get past the shitty learning curve01:50
cr1901_modernIf SCons used python3, I'd reimplement the whole damn build system for you01:51
cr1901_modernB/c I actually enjoy that01:51
cr1901_modernmithro: How is waf looking so far?01:54
mithrocr1901_modern: Looking pretty good....01:54
cr1901_modernmithro: Rereading the manual... maybe it's not as bad as I remember, but I def think "the waf book" is still difficult to read01:58

mithrorohitksingh: ping?02:14
rohitksinghmithro: pong02:14
mithrorohitksingh: Have you played with getting audio out of the TOFE Milkymist board?02:15
rohitksinghmithro: Nope. I haven't worked with TOFE Milymist board at all02:16
mithrorohitksingh: The audio codec on the Milkymist board is the same as the one Numato has a pmod module for IIRC?02:16
cr1901_modernmithro: I don't think we need to replace the litex/ components. Since waf is python3, just import migen/litex and call into that code instead? Use the python code to get rid of the makefiles and bash dependencies02:17
rohitksinghmithro: I guess so. The current sample code for the audio expansion board has only audio loopback code02:17
mithrocr1901_modern: I'm more thinking the Makefile we have and the scripts in scripts...02:18
mithrorohitksingh: Loopback code?02:18
mithrorohitksingh: As in the microphone is connected to the speaker?02:18
rohitksinghyeah...LineIn to LineOut loopback02:18

cr1901_modernI'm more thinking the Makefile we have and the scripts in scripts... <-- could you elaborate?02:19
rohitksinghmithro: yeah that one02:19
mithrorohitksingh: Seems to be the same as

tpbTitle: Port Makefile+setup scripts from shell+make to Python (maybe waf?) · Issue #335 · timvideos/HDMI2USB-litex-firmware · GitHub (at
rohitksinghmithro: yeah its definitely same02:20
mithrocr1901_modern: You are not allow to do anything until I have working spi flash stuff :-P02:20
mithrorohitksingh: So the same from there should work on the Milkymist board assuming we get the pin mapping right?02:21
cr1901_modernmithro: Well Idk Waf :P. I know SCons (what Waf forked from). But I fully support the idea02:21
rohitksinghmithro: yeah it should02:23
rohitksinghmithro: brb from office...02:26

jeaCarlFK[m]: I think I just found the remote db stuff05:09
CarlFK[m]there are a bunch of files you need starting with   - dj/dj/ # db pw, smtp05:11
jeaI have all the ones you used at lca2017, so I'm guessing most of them will still be fine05:11

CarlFK[m]  - dj/scripts/bling/{{ org }}/ # secret title.svg  doesn't have to be in that dir, it is just how I keep them organized05:12
jeais there a specific name for the title svg file? or just put a .svg file in that folder?05:13
CarlFK[m]there is a field in Client - fill that in with the filename (and path under bling05:15
CarlFK[m]there are 2 sorta unit test like things you should run:05:19
CarlFK[m](veyepar) [email protected]:~/src/veyepar/dj/scripts$ python ck_setup.py05:19
CarlFK[m]that looks at client.title, makes sure the svg exists05:20
CarlFK[m]and a bunch of other settings that have to make sense05:20
CarlFK[m]red needs to be fixed, yellow is questionable, green is good05:21

CarlFK[m]for Run Tests05:35
CarlFK[m]mostly tests the encoder05:36
jeaCarlFK[m]: I ran the script and it has loaded different config to what I expected it to05:43
jeaI've updated ~/veyepar.cfg to have pyconau, not lca, but the test still loaded lca for some reason05:43
jeaah, there is another config file in the scripts dir05:45

tumbleweedwe'd love you to look, when you get a chance15:33
*** SamSagaZ__ has joined #timvideos15:36
CarlFK[m]tumbleweed paddatrapper - any idea why hdmi2usb.hex isn't being built by travis?16:02
paddatrapperCarlFK[m]: In the prebuilt repo?16:03
tumbleweedI think because when the build was reorganised atlys was forgotten16:04
CarlFK[m]so add a hook to email paddatrapper  so he will build it for us.  easy :)16:05
CarlFK[m]I was hoping a typo or something was discovered16:06
paddatrapperhehe, probably should be added to the Travis build of the FX2 repo16:07

tumbleweedCarlFK[m]: probably copying things forward18:01
tumbleweedI should upload mode-switch to it...18:01
CarlFK[m]I copied vocto into the same ppa because it doesn't need any building because just python, right?18:02
CarlFK[m]ill try copying the fpga stuff into my ppa and rebuild18:03

tumbleweedin fact, if you copy forward to a new series, you have to select to just copy the binaries, or it'll all fail19:06

Choco31415Is there any news from Numato?23:15
mithroChoco31415: My understanding is that you want to record conferences?23:15
Choco31415mithro: Yes, especially the Ohio LinuxFest.23:15
mithroChoco31415: When is the Ohio LinuxFest?23:15
Choco31415mithro: September 29-3023:16
mithroChoco31415: Where in Ohio is it?23:18
Choco31415mithro: It's in Columbus, OH, at the convention center. (Let me google it's name...)23:19
Choco31415Hyatt Regency, Columbus, OH23:19
mithroChoco31415: Cool23:22
mithroChoco31415: What is your involvement with the conference?23:22
Choco31415mithro: So far? I'm  trying to contact them to become their streamer. I emailed them several days ago and haven't gotten a reply yet.23:24
Choco31415So far I've been poking around to see what the streming setup should be.23:26
mithroChoco31415: okay, so the first thing is to figure out if they even interested in help23:31
CarlFK[m]Choco31415 (IRC): what is the conf website?23:31

paddatrappermithro: I'm having trouble with the FIFO interface. Mainly writing to it. Do you have some reference code I can look at?23:33
Choco31415paddatrapper: FIFO specifically, or communicating with a FIFO program?23:37

tpbTitle: Karen Sandler to Keynote Ohio LinuxFest 2017 - Ohio LinuxFest (at
CarlFK[m]Choco31415 (IRC): are there talks to video both Fri and Sat?23:39
mithropaddatrapper: So the HDMI2USB UVC firmware uses the FIFO -- there is lots of docs on the Cypress website23:40
tpbTitle: AN61345 - Designing with EZ-USB® FX2LP™ Slave FIFO Interface | Cypress Semiconductor (at
mithropaddatrapper: apparently uses the FIFO interface too23:41

Choco31415CarlFK: I assume both days, although I've never been there on the first Early Bird day.23:42
Choco31415It costs money.23:42
paddatrappermithro: ok thanks. I'll check those out23:42
CarlFK[m]Choco31415 (IRC): there may be paid tutorials - get dicey recording that kind of stuff23:42
Choco31415I'm tweeting to LinuxFest as a hedge.23:43
Choco31415CarlFK: I'll make sure to ask the speakers before hand.23:44
CarlFKChoco31415: ah right... this wasn't part of the talk proposal.. you are in for some fun23:45
Choco31415CarlFK: Fun is my middle name. ;)23:45
CarlFKChoco31415: there isn't a list of talks or speakers, right?23:46
Choco31415CarlFK: They will release one before hand.23:46
Choco31415Here's 2016:
tpbTitle: Schedule - Ohio LinuxFest (at
Choco31415O, the keynote was on Friday. So I will most likely be streaming Friday+Saturday.23:47
CarlFK[m]have you tried voctomix ?23:48
Choco31415CarlFK: I'm still leaning towards OBS. It can capture audio, mix the presentation and camera streams, and record everything live.23:50
mithropaddatrapper: I'm looking at the version / commit issue at the moment23:52
Choco31415OBS is also free and open source, if that counts for anything.23:52
