| lekernel | hi Fallenou | 00:06 |
|---|---|---|
| lekernel | how was the talk? | 00:06 |
| lekernel | "A packed OSHUG this evening." | 00:07 |
| lekernel | "have just seen a glimpse of the future thanks to @yannsionneau especially for an amazing http://milkymist.org OSHUG Q&A. FPGA FTW!" | 00:07 |
| lekernel | rather good according to the twitter comments it seems :) | 00:07 |
| Fallenou | lekernel: it was great ! | 00:08 |
| Fallenou | they are really nice and interesting guys :) | 00:08 |
| Fallenou | lekernel: I met an asian guy who told me you sent him an email about selling Milkymist Ones | 00:08 |
| Fallenou | a guy that sells arduinos and sparkfun stuff | 00:08 |
| lekernel | oh yeah I spammed a lot of persons | 00:09 |
| lekernel | who were generally very dismissive | 00:09 |
| lekernel | or say "yes" and never act | 00:09 |
| Fallenou | he was thinking milkymist was not production ready yet | 00:09 |
| Fallenou | not good for his customers | 00:09 |
| Fallenou | I said well it's not reayd for VJs yet, but your customers are hackers and arduino guys | 00:10 |
| Fallenou | and it's definitely hacker ready | 00:10 |
| Fallenou | it runs RTEMS, Linux | 00:10 |
| Fallenou | it's hackers ready | 00:10 |
| Fallenou | So I don't know if he will change his mind or not | 00:10 |
| lekernel | let's get some well know person like Steve Wozniak or so to endorse it, then all those little guys will shut up and act | 00:11 |
| Fallenou | oh and I talked with the director of "get it maid" | 00:12 |
| Fallenou | err have it maid | 00:12 |
| Fallenou | made* | 00:12 |
| lekernel | hmm, what's that? | 00:13 |
| Fallenou | http://getitmade.com/ | 00:13 |
| Fallenou | ahah nice video | 00:14 |
| Fallenou | basically it's something to see if you have interested users who wanna buy your stuff | 00:14 |
| Fallenou | you put a "threshold" for manufacturing | 00:15 |
| Fallenou | and a price | 00:15 |
| Fallenou | when there is enough people in pre-order state, you can "safely" manufacture | 00:15 |
| Fallenou | knowing that you will have buyers | 00:15 |
| Fallenou | you just run the production batch when you reach the threshold | 00:15 |
| Fallenou | so that you can lower the price, (puttin a higher treshold maybe | 00:16 |
| Fallenou | taking less risks | 00:16 |
| Fallenou | that's the idea | 00:16 |
| Fallenou | lekernel: when I said you had an open source fpga toolchain as a work in progress | 00:46 |
| Fallenou | they were amazed :p | 00:46 |
| Fallenou | I hope some of the guys will come here and contribute | 00:48 |
| kristianpaul | Fallenou: (getimade) oh, i'm sorry to say but... those guys really know what _manufacturing_ really is about?? | 01:46 |
| kristianpaul | I could not be adam or wolfgang, but that is clear taht manufacuring is not behind a click and preordering.. well i should agree with sebastien, and said that for "blinling" stuff it may work | 01:47 |
| kristianpaul | (anyway personal opinion) | 01:47 |
| kristianpaul | aw_: hi | 02:32 |
| kristianpaul | Had you already talked with vendor about crystal? | 02:32 |
| aw_ | kristianpaul, not yet. any news or suggestions? | 02:37 |
| kristianpaul | i'll just about to run a self check here | 02:38 |
| kristianpaul | so nope, aw_ | 02:39 |
| kristianpaul | Is this sebastien cristial http://uk.farnell.com/citizen-america/csa309-28-63636mabj-ub/crystal-28-63636mhz-cyl/dp/1457091 ? | 02:39 |
| kristianpaul | sebastien recomendation* | 02:39 |
| aw_ | yes, exactly it is. | 02:40 |
| kristianpaul | I dont see how lekernel conclude it is overtone, yet | 02:40 |
| kristianpaul | both look same for me, at least for what i can see | 02:41 |
| aw_ | yeah...that's I was also thought. yes, I indeed didn't understand what's meaning of overtone. | 02:43 |
| aw_ | but he found that his is 2x bigger than mine. It's the real discovery that I need to watch out. | 02:43 |
| kristianpaul | indeed | 02:44 |
| aw_ | both two xtal have beedn declared with +/- 30ppm at 25 degree. | 02:44 |
| kristianpaul | yeap | 02:44 |
| kristianpaul | also by judging datasheets i will trust more in YOKE | 02:45 |
| aw_ | and CSA309 general temperature is even worse than yoktan is +/- 30 ppm. | 02:45 |
| aw_ | unless Yoktan doesn't control their products well-qualified done. | 02:46 |
| aw_ | me too. | 02:46 |
| aw_ | so btw, the 2x symbol is a real good capture. I'll watch out this. | 02:47 |
| aw_ | kristianpaul, btw, any news or thoughts from you, just let us know as always a useful input for us to think out more details. tks. | 02:50 |
| kristianpaul | k | 02:51 |
| Action: kristianpaul always fight putting memory card in his place | 03:07 | |
| kristianpaul | phew! | 03:37 |
| Action: kristianpaul got a blue screen whe trying run a patch with video_a | 03:37 | |
| kristianpaul | xiangfu: https://github.com/lekernel/m1testing/blob/master/src/tests_audio.c | 03:44 |
| kristianpaul | argg | 03:44 |
| kristianpaul | xiangfu: do you think is posible port that code a rtems command ? | 03:45 |
| kristianpaul | gn8 | 03:45 |
| kristianpaul | lekernel: had you noticed the ADV is ESD sensitive device? | 03:47 |
| kristianpaul | wolfspraul should avoid ESD warning in the mm1 box | 03:47 |
| kristianpaul | i comment ESD, because you'were doing ESD tests if remenber well | 03:48 |
| roh | esd doesnt mean immediate failiure in all cases | 03:49 |
| kristianpaul | comment about** | 03:49 |
| kristianpaul | roh: sure | 03:49 |
| kristianpaul | _just_ _saying_ | 03:50 |
| roh | sometimes its just 'damaging' the chip and it dies soon after.. or a year after that | 03:50 |
| kristianpaul | oh, yes ! | 03:50 |
| kristianpaul | hmm | 03:50 |
| roh | so i wouldnt give too much of a significance to the chip dying in _one_ single case on the board of a developer who soldered around on the board _a lot_ and used it without case most of the time i guess | 03:51 |
| kristianpaul | ;-) | 03:51 |
| roh | when the second one is dead.. please remind me;) | 03:51 |
| Schmoove | hi | 08:53 |
| Schmoove | bye | 08:59 |
| lekernel | aw_: an overtone crystal is a crystal of a lower frequency that resonates on one of its harmonics | 10:10 |
| lekernel | typically 3rd harmonic, but there are sometimes 5th overtones too | 10:11 |
| lekernel | for example, we could use a 9.54MHz crystal in 3rd overtone for generating the 28.36MHz | 10:12 |
| lekernel | (with proper oscillator dynamics, which the adv7181 doesn't have) | 10:12 |
| lekernel | it's exactly like violin players | 10:13 |
| lekernel | http://www.youtube.com/watch?v=iUDNQfePKlQ | 10:13 |
| aw_ | hmm..interesting ..now i know your meanings on 'overtone'. | 10:15 |
| aw_ | also i discovered it's a R1 50 ohm at range 10MHz <= fo <= 27MHz in foundamental mode. Since it's not sure if its the root cause, but it's good to discover/follow that we at least to use a fundamental mode xtal. | 10:19 |
| lekernel | it's probably a fundamental mode xtal... well, if you're worried, you could check that by sending 9.54MHz to it and check that it doesn't resonate | 10:20 |
| aw_ | lekernel, good capture on this mode check. btw, I'll reconfirm with here vendor and request. | 10:20 |
| lekernel | the main point is to choose an appropriate crystal for rc3 | 10:20 |
| aw_ | yeah...at least to pick that mode first. later I got a new datasheet or doc. I'll let you know. or even I just order CSA309 one. | 10:22 |
| lekernel | btw, the board already had a CSA309 crystal when it failed | 10:22 |
| lekernel | it's the board you shipped me with a non-working crystal and I replaced it right away | 10:22 |
| aw_ | uhm? wow.. | 10:22 |
| lekernel | currently the symptom is best described as: video chip power supply OK, crystal oscillating and clock running, I2C signals from the FPGA correctly measured at the chip's pins, but no I2C response from chip | 10:23 |
| lekernel | it really sounds like the adv7181 got internally damaged somehow, but this did not break the crystal oscillator | 10:24 |
| lekernel | i'll probably replace it pretty soon | 10:25 |
| aw_ | so the I2C now from decoder is no more response at all. it's really bad. | 10:30 |
| aw_ | I think that I'll need to check things as: 1, review the four supplies (DVDD/AVDD/PVDD/DVDDIO & their grounds) routes is suitable to apply enough driven power/current to chip inside? | 10:32 |
| aw_ | 2, does part unqualified at all even it works few times? 3, solderability on chip..hmm... | 10:34 |
| lekernel | yeah, I checked the solders too, I saw no lifted pin | 10:36 |
| lekernel | and I measured signals on the pin, near the package | 10:36 |
| aw_ | yeah..good, confirmed those connection by touching the pads on board not probe the package's pin directly is good. | 10:38 |
| aw_ | not sure sure current the route's thickness is good enough for chip. since i met problems before like thickness is wider enough. then either I added a more bigger value of decoupling capacitor old board or used a same capacitor value on a new re-layout board with wider thickness routes. | 10:41 |
| aw_ | this was rarely happened though. | 10:41 |
| aw_ | but our case with a likely internally damaged somehow, it's real strange. | 10:42 |
| lekernel | insufficient power traces wouldn't break i2c imo | 10:44 |
| lekernel | just cause semi-random glitches | 10:44 |
| aw_ | umm....don't know what possible accidence would cause from outside or internal. anyway i would review that all ground copper layer/area to keep a well-taken considerations. | 10:51 |
| aw_ | during rc3 routing. | 10:52 |
| wolfspraul | lekernel: you got the failure when csa309 was on the board? | 10:54 |
| lekernel | yes | 10:54 |
| wolfspraul | not that I believe there is a connection, but it's good to keep in mind. aw_ - you read that? | 10:55 |
| aw_ | yes, i just knew his board with that cas309 already. | 10:56 |
| Fallenou | kristianpaul: the getitmade stuff is not for doing the actual manufacturing, it's for being sure that you have clients | 11:00 |
| Fallenou | getitmade does not manufacture anything | 11:00 |
| lekernel | wolfspraul: vital signals (power supply, clock, i2c, reset) at the adv7181's pins are measured ok... guess the chip is simply dead | 11:07 |
| lekernel | my next step is to replace it | 11:12 |
| lekernel | roh: you have a hot air station, don't you? | 11:16 |
| lekernel | my usual technique for replacing tqfp's with little hardware is to cut the pins, remove the chip body, then lift the pins one by one | 11:17 |
| lekernel | quite aggressive :) | 11:18 |
| aw_ | um..to replace it needs hot air station is better. | 11:21 |
| lekernel | interesting: my video camera died as well | 11:31 |
| lekernel | (the one that was connected to the board when it failed) | 11:31 |
| aw_ | which color RCA con. on board you connected? green? | 11:33 |
| lekernel | yes, it's cvbs | 11:33 |
| lekernel | but maybe it's just that when dying the camera sent some overvoltage down the video cable that burnt the video chip | 11:33 |
| lekernel | it's powered on 12V so it has the potential for doing that | 11:34 |
| aw_ | this could be possible. but you need to recall how/what you did recently on camera or else...to track down any upstreams. | 11:35 |
| aw_ | so please think both your camera and m1 board. the only common ground goes through RCA connector. make sure no one else possible existed. | 11:37 |
| lekernel | the camera has its own transformer and only one RCA cable going out | 11:38 |
| lekernel | so no, it's not a ground problem | 11:38 |
| lekernel | maybe let's just add some diodes on the video input as additional protection against broken cams on RC3 | 11:39 |
| lekernel | what's the parasitic capacitance of a typical dirt cheap zener? | 11:40 |
| aw_ | have you ever tried to use multimeter to measure current. and at that time. has it ever happened that you touched the current ground probe pin? | 11:41 |
| aw_ | yeah...we can take consider to add them. | 11:41 |
| aw_ | second.. | 11:41 |
| lekernel | the board was cased when the failure happened, with no weird experiment going on | 11:41 |
| lekernel | just normal use case | 11:41 |
| aw_ | yeah...your camera is dead. but why?! checking...zener.. | 11:45 |
| lekernel | well it's an old relic from the early 90s | 11:46 |
| lekernel | i'm not surprised it died | 11:47 |
| wolfspraul | lekernel: aw_ do I understand correctly that we decided to add additional diodes on video-in for rc3? | 12:12 |
| wolfspraul | (just trying to understand the conclusion from above...) | 12:13 |
| lekernel | yeah let's do that | 12:14 |
| lekernel | i'll just check first that by replacing the video chip it still works | 12:14 |
| aw_ | i think we'd better to use bidirection diode (TVS) to protect it...still recall my sch.. before..:-) | 12:21 |
| aw_ | with just 3pF could be enough. | 12:21 |
| roh | lekernel: yes | 12:39 |
| wolfspraul | roh: another small feedback. the screws on top and bottom are torx (I think) | 12:39 |
| wolfspraul | ah no, something else, checking... | 12:40 |
| wolfspraul | hex socket? | 12:40 |
| wolfspraul | but the ones to fasten the connectors are Phillips (+) | 12:41 |
| aw_ | lekernel, I used BAV99WT1G for limit video inputs 1V(p-p) format. http://uk.farnell.com/on-semiconductor/bav99wt1g/diode-small-signal-750ma/dp/1651159 | 12:41 |
| wolfspraul | I think the best would be if they would all be the same, and the simplest (Phillips?) | 12:42 |
| roh | wolfspraul: how long ago? | 12:42 |
| roh | wolfspraul: screws got replaced.. now they should be the same size and imbus | 12:43 |
| wolfspraul | ah ok | 12:43 |
| wolfspraul | old case (my own) | 12:43 |
| wolfspraul | actually I just see top and bottom are even different on mine | 12:43 |
| wolfspraul | top is hex socket | 12:44 |
| lekernel | aw_: you mean you already have successfully used this part? | 12:44 |
| aw_ | yes, i used this parts passed ESD/EMC/FCC/CE.. :-) | 12:44 |
| lekernel | how did you connect it? | 12:45 |
| aw_ | surely some other references design used another http://octopart.com/cds3c16gth.-epcos-5371445 | 12:45 |
| lekernel | I guess you need two to protect against negative voltages too | 12:45 |
| wolfspraul | bottom is torx+slot (man! even wikipedia doesn't list that one :-)) http://en.wikipedia.org/wiki/Screw_drive | 12:45 |
| aw_ | in parallel to 75 ohm but in front of it. | 12:45 |
| lekernel | hmm ok, but there are two diodes in these devices | 12:46 |
| lekernel | which ones do you use and how? | 12:46 |
| aw_ | yes..so I said it's better that to use a TVS part. :-) | 12:46 |
| wolfspraul | roh: all are inbus now? (inbus = allen = hex socket) | 12:46 |
| wolfspraul | including the ones fastening the connectors? | 12:47 |
| wolfspraul | all the same inbus size or different ones? | 12:47 |
| lekernel | the breakdown voltage of the TVS part is 150V | 12:47 |
| lekernel | that's way too much | 12:48 |
| lekernel | we don't want to protect against esd here, but against overvoltage generated by faultly video sources | 12:48 |
| wolfspraul | btw - Elphel includes 3 different sized inbus keys with all their cameras, with those you can open every last screw in the camera | 12:48 |
| roh | wolfspraul: the ones on top and bottom are | 12:48 |
| lekernel | what we want is some device that clamps the voltage on the video inputs to a reasonable range, say +/- 2V | 12:49 |
| roh | heh.. do 2 antiparallel 5.5V zehner count? | 12:49 |
| wolfspraul | roh: did you find black screws for midi/dmx/video now? do you still think that's desirable? | 12:49 |
| roh | wolfspraul: nope.. didnt find them for the video | 12:50 |
| wolfspraul | for the video-in, there is a lot of silverish look already anyway, for dmx black would probably look better | 12:50 |
| roh | i can get st2.9 in black (dmx) but not st2.2 (cinch) | 12:50 |
| aw_ | i used BAV99WT1G ...yes,but I only connect one terminal to +5V and the other terminal connected to GND, the third one is connected to cvbs. | 12:51 |
| wolfspraul | why can't the top and bottom screws be phillips as well, like video/dmx ? | 12:51 |
| roh | uh fuck | 12:52 |
| roh | just read about japan | 12:52 |
| terpstra | it's insane | 12:52 |
| terpstra | 8.9 earthquake and 10 meter wave | 12:52 |
| terpstra | massive destruction along their entire coast | 12:53 |
| Action: kristianpaul reading the "From the bitstream to the netlist" paper | 12:55 | |
| aw_ | lekernel, with BAV99WT1G we surely can clamp the undesired voltage. | 12:55 |
| lekernel | forward voltage is too low... or, well, it'd sink 50mA at 1V | 12:56 |
| lekernel | that's too much | 12:56 |
| lekernel | we should use a zener | 12:56 |
| lekernel | or two of these diodes in series | 12:57 |
| lekernel | and the same for negative voltages, that's 4 diodes in total | 12:57 |
| aw_ | well...we can decide and find other similar one to meet our decoder. | 12:58 |
| aw_ | it surely can be alternative as you said with 4 diodes in total. | 12:58 |
| kristianpaul | wolfspraul: fyi, a full flashing for the mm1 take 1m19s | 13:14 |
| wolfspraul | kristianpaul: that's with high-speed fix, right? | 13:15 |
| kristianpaul | wolfspraul: yeap | 13:15 |
| wolfspraul | too bad we don't have a number to compare without the fix (no need to test it...) | 13:15 |
| wolfspraul | 1.19, hmm | 13:16 |
| wolfspraul | what do we do in those 80 seconds? | 13:16 |
| kristianpaul | you can compare with xilinx cable | 13:16 |
| kristianpaul | write to the nand flash | 13:16 |
| wolfspraul | load the entire 32mb blob via jtag and write it into nor flash? | 13:16 |
| wolfspraul | it's nor | 13:17 |
| kristianpaul | is no 32Mb at all | 13:17 |
| kristianpaul | ah ok | 13:17 |
| kristianpaul | bitstream + bios + rescue + flicernoise | 13:17 |
| kristianpaul | i dint include data filesystem | 13:17 |
| wolfspraul | how much is written roughly? | 13:19 |
| wolfspraul | guess I was disconnected | 13:23 |
| kristianpaul | 4000k | 13:23 |
| kristianpaul | aprox | 13:23 |
| wolfspraul | kristianpaul: how many MiB are transferred in those 79 seconds? | 13:23 |
| wolfspraul | so that's 50 KiB / second | 13:24 |
| kristianpaul | hmm, i missed flickernoise | 13:25 |
| kristianpaul | but you get an idea | 13:28 |
| wolfspraul | yes, sure | 13:28 |
| Fallenou | flickernoise is like 9 MB iirc | 13:29 |
| Fallenou | so you miss a lot :p | 13:29 |
| kristianpaul | Fallenou: lzma ;-) | 13:30 |
| Fallenou | oh flickernoise is uncompressed by the bios at boot time ? | 13:30 |
| kristianpaul | yeap | 13:30 |
| Fallenou | oh nice | 13:30 |
| kristianpaul | not so.. as you some seconds delay | 13:31 |
| kristianpaul | at least for me | 13:31 |
| Fallenou | well if you flash your board a lot it's interesting | 13:31 |
| kristianpaul | :-)) | 13:31 |
| Fallenou | maybe for end users it would be better to boot faster | 13:31 |
| kristianpaul | anyway, i think pdf stuff should be optional, as is not fully behave as anyone can expect | 13:32 |
| kristianpaul | s/is/it | 13:32 |
| Fallenou | you tried reading a pdf ? did it work ? | 13:32 |
| kristianpaul | it work | 13:32 |
| kristianpaul | is slow | 13:32 |
| Fallenou | :x | 13:33 |
| kristianpaul | loading pdf and zooming | 13:33 |
| kristianpaul | so is usefulness for me, also add more boot delay.. | 13:33 |
| kristianpaul | but i can read pdf, thats good :-) | 13:34 |
| lekernel | yeah, i'll make this feature optional | 13:38 |
| lekernel | it could be possible to make the executable lighter though, by removing fonts and cmaps from mupdf | 13:38 |
| lekernel | it'd be great if you could figure out how to do btw :) | 13:38 |
| lekernel | the mupdf says several MB can be saved by removing these things | 13:38 |
| lekernel | mupdf website | 13:39 |
| lekernel | also, when reading light pdfs like flickernoise help (which is the intended purpose) it's not that slow | 13:39 |
| kristianpaul | i was reading sysctl.pdf and still slow tought | 13:39 |
| kristianpaul | remove = rm -f *.o ;-) | 13:41 |
| lekernel | ? | 13:41 |
| kristianpaul | nv | 13:41 |
| kristianpaul | why not just loading pdf as raw images? | 13:41 |
| kristianpaul | mm1 is not a general purpose pdf reader so you can cheat | 13:42 |
| Fallenou | oh yes just displaying the pages one by one | 13:44 |
| Fallenou | displaying screenshots of the pdf | 13:44 |
| Fallenou | will be faster and lighter | 13:44 |
| Fallenou | humm lighter not sure cause maybe the images can be heavy, dunno | 13:45 |
| Fallenou | but faster | 13:45 |
| lekernel | it's not as classy as just dumping a pdf on the flash via ftp or memory card and reading that directly :p | 13:47 |
| Fallenou | sure not as classy :) | 13:47 |
| lekernel | and, also, this pdf reader is also a demonstration of mm as general purpose computer, running 3rd party software (mupdf) | 13:48 |
| Fallenou | I wonder how hard it would be to port a graphic terminal emulator | 13:48 |
| Fallenou | like the simplest one | 13:48 |
| kristianpaul | from busybox? | 13:49 |
| Fallenou | xterm maybe | 13:49 |
| kristianpaul | ah | 13:49 |
| kristianpaul | note the X <- | 13:49 |
| Fallenou | one that does not use gnome/kde/whatever lib | 13:49 |
| Fallenou | humm yes :( | 13:49 |
| Fallenou | maybe it's easy to remove the X part | 13:49 |
| Fallenou | dunno | 13:49 |
| kristianpaul | (general purpose computer) when running something like linux may be | 13:49 |
| kristianpaul | atleast you want fork rtems in something else.. :-) | 13:50 |

| Fallenou | ahah : http://home.comcast.net/~fbui/http://home.comcast.net/~fbui/ | 13:51 |
| lekernel | Fallenou: just write one | 13:51 |
| Fallenou | I guess it's not easy | 13:51 |
| Fallenou | better porting one | 13:52 |
| kristianpaul | mtk.. | 13:52 |
| Fallenou | xterm seems to be the "simplest" one but i'm searching | 13:52 |
| lekernel | Fallenou: it _is_ easy | 13:52 |
| lekernel | you don't need to be a rocket scientist to write strings in a framebuffer, do you? | 13:52 |
| lekernel | with small features like scrolling, colors, position, etc. | 13:53 |
| Fallenou | I don't know, I've never looked at how a terminal emulator works | 13:53 |
| Fallenou | isn't it supposed to behave like vt100 or something ? | 13:53 |
| kristianpaul | -e: unknown command.. | 13:53 |
| Fallenou | with a lot of features to support | 13:53 |
| Fallenou | I've been told that linux terminal emulator is quite a complex thing | 13:54 |
| lekernel | yeah, but that's only because the unix/linux termios API is about as fucked up as Xilinx software | 13:54 |
| Fallenou | http://code.google.com/p/fbterm/ <= :) | 13:54 |
| lekernel | you don't need all those features | 13:54 |
| lekernel | well, actually i'm not sure if "feature" is an appropriate word | 13:54 |
| Fallenou | =) | 13:54 |
| Fallenou | in any case before writting somethign I look around to see if this already exists | 13:55 |
| lekernel | that's basically a toxic waste dump of cruft from the 70s era when computers used mechanical typewriters as "screens" | 13:55 |
| Fallenou | yes it's a legacy thing | 13:56 |
| Fallenou | if i understand correctly | 13:56 |
| Action: kristianpaul :-) | 13:56 | |
| Fallenou | what do you think of the last one ? | 13:56 |
| Fallenou | fbterm | 13:56 |
| lekernel | you don't need windows | 13:57 |
| Action: kristianpaul will keep using the serial port | 13:57 | |
| lekernel | mtk already has a windowing system | 13:57 |
| lekernel | if you can take out the windowing part, good | 13:57 |
| Fallenou | humm yes I see | 13:57 |
| lekernel | also, you could also have a look at the framebuffer tty emulation system in the linux kernel | 13:57 |
| lekernel | and at least we know this code works | 13:58 |
| lekernel | but really, you don't need anything complicated | 13:58 |
| kristianpaul | (general purpose computer) when running something like linux may be more general :-) | 13:58 |
| Fallenou | ok | 13:58 |
| lekernel | kristianpaul: sure, but it also shows that you don't need GNU/Linux to run programs like mupdf :) | 13:58 |
| kristianpaul | lekernel: indeed | 13:59 |
| lekernel | Fallenou: if you add this terminal feature, "hide" it | 13:59 |
| lekernel | ie instead of a button in the control panel, use a key combination, like ctrl-alt-t | 14:00 |
| Fallenou | ok | 14:01 |
| kristianpaul | hmm the line out noise still there even if i do a software mute | 14:42 |
| lekernel | Fallenou: is there a recording of the oshug talk? | 14:51 |
| Fallenou | I think no | 14:53 |
| Fallenou | just a few pictures | 14:53 |
| Fallenou | http://oshug.org/event/8 | 14:53 |

| lekernel | I want some of what lattice people are smoking | 15:38 |
| Fallenou | LOOL | 15:42 |
| Fallenou | wtffff | 15:42 |
| lekernel | "that's what I call green technology" | 15:43 |
| Fallenou | :'' | 15:43 |
| roh | wtf | 16:02 |

| kristianpaul | Fallenou: any interesting question from OSHUG talk? | 16:44 |
| kristianpaul | nice pics btw :-) | 16:44 |
| Fallenou | hehe thanks | 16:44 |
| Fallenou | yes a loooooot of questions | 16:44 |
| Fallenou | I managed to answer to most of them | 16:44 |
| Fallenou | for one or two I had to say that I didn't know and redirected the guys to the ML / IRC | 16:44 |
| kristianpaul | What you use mac?? ;-) | 16:45 |
| Fallenou | they were very interested | 16:45 |
| Fallenou | yes :p I apologized for that at the beginning | 16:45 |
| kristianpaul | haha | 16:45 |
| Fallenou | but some of them are using mac too | 16:45 |
| Fallenou | so it was ok ;) | 16:45 |
| kristianpaul | You shoudl use mm1 next time for, i dont see better way of showing the product you're talking about works | 16:45 |
| Fallenou | I would if I had one :p | 16:46 |
| kristianpaul | ah, yes.. | 16:46 |
| Fallenou | at least I showed pictures and videos from vimeo | 16:46 |
| kristianpaul | Man you need to by one too ! :-) | 16:46 |
| kristianpaul | just tww left | 16:46 |
| kristianpaul | twO | 16:46 |
| Fallenou | yeah for the moment I am paying my rent in London and I will see what's left of my bank account :) | 16:50 |
| kristianpaul | :| | 16:50 |
| Action: kristianpaul used credit card to pay mm, so well, i pay bill as anynone does | 16:51 | |
| lekernel | my opinions about London and what costs what there could be compared to those on autocrap, so I won't comment on that | 16:51 |
| Fallenou | you're working on your communication skills ? :p | 16:52 |
| kristianpaul | ;-) | 16:53 |
| kristianpaul | 14:36 * Fallenou is back | 17:03 |
| kristianpaul | 14:37 < Fallenou> no no dma | 17:03 |
| kristianpaul | Fallenou: can you exaplaing what was that? | 17:03 |
| Action: Fallenou scrolling up | 17:03 | |
| kristianpaul | lekernel: is the xbar doing something usefull right now? | 17:04 |
| kristianpaul | I saw the comit is from 10/2010 | 17:05 |
| Fallenou | sorry I can't scroll up that far kristianpaul :x | 17:06 |
| kristianpaul | also, can you make a quick explanation of the DMA between TMU and wishbone, i mean how do you avoid a botleneck if TMU is par of the FML | 17:07 |
| kristianpaul | ? | 17:07 |
| kristianpaul | Is tha the xbar for? does it work well? how it works? (i really dunno) | 17:08 |
| Action: Fallenou leaves the office | 17:08 | |
| kristianpaul | For save some chatting i'm okay if you point me a documentation to read, i lack good links/books/whatever about this topic | 17:09 |
| kristianpaul | or for easy is this http://milkymist.org/socblock.png diagram updated? | 17:10 |
| Action: kristianpaul find an article about bus mastering in wikipedia | 17:14 | |
| Action: kristianpaul wonders why serial boot was removed from the bios boot order | 17:16 | |
| Fallenou | it was kind of slow I guess | 17:18 |
| kristianpaul | what was slow? | 17:19 |
| Fallenou | serial booting | 17:19 |
| kristianpaul | ah yes | 17:19 |
| lekernel | anyone knows a good free replacement wallpaper that looks like http://my-blackberry.net/wallpapers/11/m/Fluorescence.jpg ? | 17:31 |
| lekernel | this one looks great, and wouldn't be too bright (we'll also need a dark MTK color theme too) | 17:31 |
| lekernel | but it's not free | 17:31 |
| kristianpaul | https://secure.wikimedia.org/wikipedia/commons/wiki/File:Fluorescence_of_Aesculin.JPG | 17:32 |
| kristianpaul | :p | 17:32 |
| lekernel | switching between the dark patch rendering and the bright GUI definitely hurts the eyes when you're on a big screen | 17:32 |
| kristianpaul | hehe yes | 17:33 |
| lekernel | hmm... not the best quality picture :( | 17:33 |
| lekernel | we can use LCARS colors for extra nerd points | 17:33 |
| kristianpaul | I have some artwork for a radiohead album but dunno license.. | 17:34 |
| lekernel | if it's on a radiohead album it's probably non-free... no? | 17:34 |
| kristianpaul | i think | 17:34 |
| lekernel | http://curlybracket.net/2010/03/01/light/ | 17:38 |
| kristianpaul | hah http://www.flickr.com/photos/jakobbg/2788486554/sizes/z/in/photostream/ | 17:39 |
| kristianpaul | by 2.0 | 17:39 |
| lekernel | but nc-nd | 17:39 |
| lekernel | kristianpaul: hmm I doubt it | 17:39 |
| kristianpaul | hehe | 17:39 |
| lekernel | everything from digitablasphemy.com is non-free | 17:39 |
| kristianpaul | http://www.flickr.com/photos/snickclunk/202909801/sizes/l/in/photostream/ | 17:40 |
| lekernel | does preloading some wallpapers into the m1 qualify as commercial use? | 17:40 |
| kristianpaul | yes | 17:40 |
| kristianpaul | you sell it, thats is "content" | 17:40 |
| lekernel | dunno... it's a bit of a gray area for me | 17:41 |
| lekernel | I can ask for a specific permission anyway | 17:41 |
| Fallenou | just to be sure I guess it's better to avoid anything in nc-by | 17:42 |
| lekernel | I agree, but in the absence of a good !nc !nd alternative it's better than nothing | 17:43 |
| lekernel | for things like the wallpaper, which is just a preloaded file on the FS, we don't have to be super-picky about freedom of the content (as long as we have the permission from the author to use it in this way)... let's get things done | 17:44 |
| kristianpaul | http://www.flickr.com/photos/ellenm1/3736386994/ | 17:47 |
| kristianpaul | i love this http://www.flickr.com/photos/andrewdyson/3048981752/ | 17:48 |

| wpwrak | lekernel: (lattice) don't smoke their stuff ! after that, you must be pissing brain cells | 18:50 |
| wpwrak | tuxbrain_away: do you still need files from me for your atben/atusb fab quote or have you already generated them yourself ? | 19:09 |
| wpwrak | oops, wrong channel | 19:09 |
| kristianpaul | haha ;-) | 19:09 |
| Action: kristianpaul back from snap | 19:09 | |
| kristianpaul | s/snap/nap | 19:12 |
| kristianpaul | lekernel: with current conbus in mm up to how manye slaves and masters are supported? | 19:15 |
