nancyHello can anyone help me , that while setting up the environment instead of (H2U P=opsis) #, why there is (LX P=opsis)05:45
CarlFKnancy:  export PLATFORM=opsis06:11
tpbTitle: HDMI2USB-litex-firmware/ at master · timvideos/HDMI2USB-litex-firmware · GitHub (at
CarlFKer, sorry, not that.06:11
nancyi had already done that sir ,06:15
CarlFKswell.  my prompt is (LX P=opsis R=???)06:27
*** sb0 has joined #timvideos06:29
CarlFK                Target: video (default: video)06:29
nancyshouldnt it be H2U P=opsis , so that u can flash it ?06:31
CarlFKthis is for building, I don't use it for flashing06:32
CarlFKexport TARGET=<targetname>06:33
CarlFKthis looks like it..06:33
CarlFKI'm thinking that docs are wrong about what the prompt should be06:35
CarlFKlx may stand for litex06:35

nancythere is HDMI2USB_video_lm3206:36
nancythere is no HDMI2USB_video_lm32  ( corrected)06:37
nancyfor any change in pattern.c made by me i want to check if it is working or not .06:40

paddatrappernancy: make a note of what issues you have had and what has needed changing around following the docs - it would be useful to update the docs to reflect how to actually build the firmware07:43
CarlFKnancy: flashed, connected, H2U 00:02:00>verion,   git describe: v0.0.4-197-gdaf33bc07:48
CarlFKso thats good.07:48
nancyis there an inverted pattern07:49
CarlFKnow I have to remember how to enable it07:50
nancy@paddatrapper yes sir ! i ll send pull .07:50
paddatrappernancy: thanks07:50
CarlFKpattern (p) - select next pattern07:51
CarlFKnancy: I think you need to modify the  "pattern command" so yours can be selected07:56
CarlFKsorry, I should have mentioned that07:56
CarlFKH2U 00:09:39>help07:57
CarlFKAvailable commands: ....07:57

CarlFKH2U 00:11:00>p07:57
CarlFKPattern now 007:57
nancybut sir i didnt made  a great change , just inverted the colors in the existing pattern07:57
nancyto see if it would work07:57
CarlFKoh, let me look at that again07:58
nancyright now just focusing if it shows up ! so i dint add any new pattern07:58
CarlFKarg.  I flashed the wrong version: built: Apr  8 2018 19:35:1507:59
CarlFKit is 3am, im not doing to well :p07:59
CarlFKwell.. history shows: hdmi2usb-mode-switch -v --flash-image top.bin08:00
nancyoh timezones ! i forgot to notice that ...08:00
nancysir we can look later if it is not fine now !08:01
CarlFKApr  8 isn't right08:01
CarlFKI can stay up a little more, just forgive me for making mistakes08:02
nancyNo problem sir , i have been learning a lot , while working on given tasks08:03
CarlFKnancy: ok, I give up = im going to bed...08:15
CarlFKbut the next task is to figure out why version says built: Apr  808:15

paddatrapperopsis flashed, just checking build date, etc. I won't be able to check output as I am not currently in front of an opsis09:13
*** Guest99946 has quit IRC09:20
paddatrappernancy: what is the output of date on your machine?09:22
nancyFri Apr 13 14:50:22 IST 201809:24
paddatrapperand and what is the first commit listed by git log? git log | head -n 1009:27
tpbTitle: Ubuntu Pastebin (at
nancy oops this09:31
tpbTitle: Ubuntu Pastebin (at
paddatrapperok cool. Seems the firmware generates the build date from the date of the last commit, not the date that it was actually built. So looks like everything is fine that I can check09:32
paddatrapperCarlFK: will have to check the actual pattern when he wakes up09:32
paddatrapperor I can do it when I get home in about 4 or 5 hours09:32
nancyyes sir , so i ll make a pull for getting file09:33

CarlFKgm folks13:29
CarlFKbuild date from the date of the last commit  - ah, that explains that.13:29
tumbleweedthat's sane13:30
*** samty has joined #timvideos13:30
paddatrapperCarlFK: that looks like the normal pattern to me...13:36
paddatrapperI wonder what she meant by inverted the colours13:37
CarlFKI have on idea..:13:37
CarlFKtake the red from the top and put it on the bottom :p13:37
paddatrapperHaha, true...13:38
paddatrapperBut build env is setup. And should result in a PR from her updating docs13:39
paddatrapperCarlFK: on your test rig make gateware segfaults after checking clocks. I ran out of time to debug properly, but I hope to do so some time13:40
CarlFKpaddatrapper:  swell :p13:40
paddatrapperAre there any pointers for build env set up on Debian? Adding PPA fails because of signature issues in apt in bootstrap script (also ran out of time to debug properly)13:42
*** rohitksingh has joined #timvideos13:42
CarlFKpaddatrapper: search irc logs ;)13:42
paddatrapperCarlFK: heh, sure will do13:43
CarlFKor bug tumbleweed ^^13:43
CarlFKis there a doc framework that is interactive, like pick these options, get docs: distro, board, dev/production, testing/stable13:44
tumbleweedwhy do you need the PPA?13:45
CarlFKtumbleweed: I'm guessing because the doc says so13:45
tumbleweedI think I just commented out all the bits of the bootstrap script that I didn't like the look of :P13:45
CarlFKtumbleweed: send me a .patch and I'll add it to my ansible :p13:47
CarlFKmostly kidding.  that would be awful.13:47
mithroThe PPA is only needed for Atlys boards IIRC13:53
mithropaddatrapper: re date - it does!? That is cool!13:54
paddatrappermithro: well a build from today shows as built 8 April, the date of the last commit13:55
mithroProbably best to change the info from "built date" to "latest commit date" or something13:55
paddatrappertumbleweed: heh, thought that may have been the case. May be an idea to refractor to allow toggling things like that13:55
mithropaddatrapper: I'm still a bit skeptical13:56
paddatrappermithro: I can do some more testing13:56
mithropaddatrapper: I think the date comes from the version generate script?13:57
tumbleweedpaddatrapper: yeah, I've done that for some of the things13:57
tumbleweedbut mostly in enter-env rather than bootstrap13:57

CarlFKit would make this 'remote testing' nice if there was a simple way to tack on a string that shows up on version/pattern14:00
CarlFKis using the build machines hostname ok?14:01
CarlFKgit branch: master14:01
CarlFKnever mind.  make a branch, done.14:02
mithroI don't see a date there?14:02

CarlFKnancy: here is the testpattern:
*** rohitksingh has quit IRC14:04
nancythere is no change :(14:06
CarlFKnancy: can you describe what you were expecting to see?14:07
CarlFK"inverted" isn't enough14:08
paddatrappermithro: seems that the version generation script doesn't generate date14:08
paddatrappermithro: or at least it isn't included in the generated version_data.c file14:09
*** nancy has quit IRC14:10
