tumbleweedmithro: there?08:15
mithrotumbleweed: kinda08:15
tumbleweed(you probably want to hide from me :P )08:15
tumbleweedI've just unboxed an opsis, and am wondering what to do with it, next08:15
mithrotumbleweed: what do you want do to with it :P08:16
tumbleweedI see nothing on the USB bus08:16
tumbleweedthat's bad, right?08:16
tumbleweedor are they not yet flashed?08:16
mithrotumbleweed: possibly08:16
mithrotumbleweed: How have you connected it up?08:17
tumbleweedthis is on JUSB208:17
tumbleweedpower & usb, nothing else08:17
mithroYes, if you have plugged in JUSB2 then you should get something on the laptop08:18
mithrotumbleweed: what is the position of the JFX2-RST jumper?08:19
mithrotumbleweed: are any of the LEDs lit?08:22
tumbleweedD10 and D1 on power-up08:22
tumbleweedthen D1 turns off08:22

tumbleweedI could go and grab another opsis board from my hotel room, but that'll take half an hour08:25
mithrotumbleweed: Can you power down the board, move the jumper to 1-2 then power it up again?08:25
tpbTitle: debian Pastezone (at
mithrotumbleweed: are you connecting this via a USB hub or something?08:28
mithrotumbleweed: can you try removing JFX2-SDA / P18?08:31
tumbleweedleave JFX2-RST on 1-2 ?08:31
mithrotumbleweed: yes08:31
tumbleweedmithro: same deal08:32
mithrotumbleweed: hrm...08:32
mithrotumbleweed: the boards were all tested before shipping08:32
* tumbleweed just tried with olasd's laptop - same thing08:34
mithrowith those two jumpers set the way I described you are just testing the FX2 file seperately from the FPGA08:35
* tumbleweed thinks he should go get another one08:36
mithrosounds like it08:36
_florent_mithro: pong08:49
*** se6astian|away is now known as se6astian09:10
* tumbleweed is back09:28
tumbleweedapparently this one works09:31
tumbleweedso, what's the warranty procedure? :)09:33
*** olasd has joined #timvideos10:33
* olasd waves from Vienna10:33
mithroHi olasd, who are you? :P10:33
mithrotumbleweed: first step would be to figure out what is going on10:34
tumbleweedmithro: yeah10:35
olasdmithro: I'm someone with an opsis board plugged into his laptop10:35
mithroolasd: ahh10:35
mithrotumbleweed / olasd: so, there is something going on in Vienna at the moment?10:35
tumbleweedmithro: yeah, a mini debconf10:36
mithroyou'll probably want to put a newer Opsis firmware onto the board so you can get the debugging output10:36
mithrocr1901_modern1: ping?10:36
tumbleweedmithro: I'm trying to remember if I flashed an opsis at LCA10:37
mithrotumbleweed: I'm pretty sure I showed you how, but you should just be able to use "make flash" now10:37
tumbleweeddoes that depend on conda stuff?10:38
mithrotumbleweed: yes10:38
* tumbleweed shall try find how I did this before10:38
mithrotumbleweed: the "make flash" is part of the developer environment stuff10:39
tumbleweedmithro: so, we're getting a test pattern out of this second board10:40
tumbleweedbut we can't get into the serial console10:40
tumbleweedit just doesn't respond10:41
tumbleweedbut, flashing could change all of that :P10:41
mithrotumbleweed: what are you using to connect to it?10:41
mithroolasd: what is the screen command line you are using?10:42
mithrocan you try flterm?10:42
tumbleweedmithro: remind me. Can I flash the opsis with fxload?10:43
mithrotumbleweed: fxload loads firmware into the RAM on the FX2 IC10:44
tumbleweedyeah, flterm works10:44
tumbleweedon the plus side, this opsis seems to be working perfectly10:48
olasdmy fonts are huge now10:49
tumbleweedolasd will experiment with flashing, I think10:50
tumbleweedmithro: can we flash it in this state?10:50
mithrotumbleweed: should be able too10:50
tumbleweedok, while he plays with that, I'm going to play with the working one10:51
mithrooh wait10:51
mithroyou mean "can we flash the non-working one"10:51
mithroYou can't flash the non-working one unless you can see the FX2 on the USB bus10:54
mithroUnless you have a JTAG programmer of some other sort?10:54
*** panther has joined #timvideos11:04
*** panther is now known as sab_12311:09
tumbleweednope, no JTAG programmers around that I know of11:12
tumbleweedbut I'm sure I can find someone in cape town, with one11:12
tumbleweedso, i guess we can flash a newer firmware on the third board (which presumably works)11:14
cr1901_modern1mithro: pong11:14
mithrocr1901_modern1: Do you think you could port to migen/misoc?11:15
tpbTitle: High Speed Frequency Counter - Hamsterworks Wiki! (at
cr1901_modern1mithro: Yes. In fact, I already have part of it from that botched pull request back in Jan. Right now however, there is a problem with how it counts (the number of events logged per second is uneven when used with a PLL, and downright wrong when fed with an input divided by the global cloc)11:18
mithrocr1901_modern1: The interesting thing about that code is that it can measure really fast frequencies11:19
mithrocr1901_modern1: I'm interested in attaching it to the clock pins on HDMI11:19
cr1901_modern1Well, field_hamster has done a lot of impressive stuff; I'll take a look :). But yes, porting to MiSoC/Migen shouldn't be a problem11:20
cr1901_modern1"Even if the count is synchronized using cascaded flip-flops errors will still occur"... hmmm, interesting. I guess he figured that out from experience, but still interesting11:35

CarlFKmithro: how do we order more boards?14:33
FooBari'm assuming through crowdsource ?14:34
CarlFKFooBar:  "No Longer Available   "14:36
tpbTitle: Numato Opsis: FPGA-based open video platform | Crowd Supply (at
FooBari'd like more too... (somewhere next year ;P )14:37
FooBarseems 3 wasn't enough yet14:37
olasdso, to make "make flash" work on the opsis board, how should it be jumpered? I can't seem to find the correct info14:57
CarlFKolasd: I think the way it shipped15:06
CarlFKI havent changed jumpers on mine, but i haven't flashed either.  just what I observed at LCA15:06
CarlFKand I won't have time to do anything for about 4 days ... grumble15:07

olasdCarlFK: looks like I'm in the situation; JFX2-RST jumper is in 2-315:30
tpbTitle: does not tell me how to update the firmware · Issue #218 · timvideos/HDMI2USB-misoc-firmware · GitHub (at
CarlFKolasd: umm.. :(15:33
CarlFKThat was as far as I got15:33
CarlFKolasd: the good news is I am able to use it without updating ....15:35
CarlFKwhich is why I didn't push harder15:35
olasdright; we would like to try out some of the video modes that are in newer firmwares15:36
olasdI followed up on the bug15:53

tumbleweedCarlFK: our VGA->HDMI adaptors don't present a 720p mode but do present a 1080p one16:35
tumbleweedso, putting the board in 1080p mode16:35
CarlFKtumbleweed: oh swell16:35
tumbleweedwould be nice16:35
tumbleweedsomeone here apparently has experience with programming these things16:36
CarlFKrohitksingh: finish your vga code!!!!16:36
CarlFKyay for someone!16:36
