**** BEGIN LOGGING AT Thu Oct 22 02:59:58 2015 Oct 22 04:20:50 anyone have experince with dvi out from the BeagleBoard-xM? I'm trying to connect to my DELL u2412m LCD with a hdmi-dvi cable, but the monitor complains. Oct 22 04:21:13 this is what the monitor reports on the desktop (xrandr output) http://vpaste.net/vkC5b Oct 22 04:24:12 I've tried adding dvimode=1024x768MR-16@60 and 800x600MR-16@60 in uEnv.txt but that didn't change anything Oct 22 04:26:20 let me log in more permanently here :) bye damjan__ Oct 22 04:28:39 zmatt. thanks Oct 22 04:30:08 damjan: do you have a serial console on the XM? Oct 22 04:30:37 av500: not currently. I'll have to get it tomorrow Oct 22 04:32:54 I wonder if defaultdisplay=dvi is the default? Oct 22 04:35:55 I guess I cant continue tonight Oct 22 13:46:47 Hi.... Oct 22 13:46:59 can everyone help me plz... :-( Oct 22 13:47:25 ...no... Oct 22 13:49:19 Hi... Oct 22 13:50:16 how can i change my USB-IP Address from my BEaglboard ! i have to connect two Board with some PC. and i have always the Conclit IP Addres with 192.68.7.2 Oct 22 13:50:34 conclit= conflict Oct 22 13:51:37 any Idea... :) !? Oct 22 13:55:09 Hello..... Everybody here !!!? Oct 22 13:55:12 :-O Oct 22 13:57:57 http://www.catb.org/esr/faqs/smart-questions.html Oct 22 13:58:57 have you tried looking at the scripts in /opt? Oct 22 13:59:08 which distribution are you running? Oct 22 14:27:19 hi... Oct 22 14:27:54 3.8.13-bone70 #1 SMP Fri Jan 23 02:15:42 UTC 2015 armv7l GNU/Linux Oct 22 14:30:29 looks like a standard debian Oct 22 14:31:45 yes.. Oct 22 14:32:13 i have make this tutorial Oct 22 14:32:15 http://ewong.me/changing-usb0-ip-address-on-the-beaglebone-black/ Oct 22 14:32:35 but then i can not connect with my usb Oct 22 14:33:45 yes, that looks correct. make sure to change all 3 files Oct 22 14:35:29 ok i try to make it Oct 22 14:35:42 thank u very mush Oct 22 15:28:10 Does anyone have a solution for flashing multiple BBBs at a time? Oct 22 15:28:40 multiple microSD cards Oct 22 15:28:58 I was hoping to use PXE to boot from the network, but it doesn't look like the BBB supports that... Oct 22 15:29:28 not pxe Oct 22 15:29:33 thisisbrians, you should be able to use u-boot's netboot ability to pull a kernel and dts via TFTP and then get your rootfs via NFS or tftp, too Oct 22 15:29:46 yes Oct 22 15:31:12 bradfa: that was my next inkling. Could I then image the onboard flash without issue once booted from a remote rootfs? Oct 22 15:33:50 thisisbrians, "onboard eMMC"... it's all up to your eMMC writing script... Oct 22 15:37:10 rcn-ee: I am currently using a microSD card built with your eMMC flasher image creator for my own custom image. Oct 22 15:38:17 That works great for writing to the eMMC when using a microSD card (way faster than just dd'ing the whole thing, as you well know). I was hoping I could do something similar from netboot to avoid the sd card entirely. Oct 22 15:41:00 thisisbrians, here's an idea.. tftp boot into ram based initramfs, nfs mount, then use this script: https://github.com/RobertCNelson/boot-scripts/blob/master/tools/eMMC/init-eMMC-flasher-from-usb-media.sh Oct 22 15:41:22 ^ that script could be hacked to nfs mount and grab the *.img.xz *.bmap files.. Oct 22 15:46:45 rcn-ee: thanks. so get those files over the network via nfs instead of from usb, right? Oct 22 15:49:51 thisisbrians, correct, switch the script instead of mountin /dev/sda1 to 192.x.x.x.x:/opt/xyz/ Oct 22 15:50:46 remember, you'll need to hack up an initramfs to add nfs usersapce support.. Oct 22 15:59:38 thisisbrians, BBBlfs is another option .. and rcn-ee did some work chain-loading it .. kinda .. Oct 22 15:59:47 or not. Oct 22 16:00:12 that would work too, but you'd need to also add nfs upport, but that would be easier i think as he used buildroot.. Oct 22 16:16:11 rcn-ee, stt_michael: thanks. i'll see what i can cook up. Oct 22 16:17:59 <_av500_> thisisbrians: note that you can also boot a BBB from a PC Oct 22 16:18:13 <_av500_> so you could hook up a few to a PC and flash them like that Oct 22 16:18:44 <_av500_> https://github.com/ungureanuvladvictor/BBBlfs Oct 22 16:19:57 thisisbrians, .. as _av500_ describes .. and you can, in fact, cascade them .. Oct 22 16:20:16 to a point. Oct 22 16:20:31 but bbblfs works Oct 22 16:23:41 _av500_: ah i see...that looks really interesting. can i modify u-boot to avoid having to hold S2 during power up? Oct 22 16:24:41 thisisbrians, usb boot, is after mmc... so you need to force (microSD) without a card present.. Oct 22 16:27:20 solder the s2?! Oct 22 16:27:22 lol Oct 22 16:28:31 haha Oct 22 16:29:19 i'm talking a bit over my head...i guess there isn't software anywhere that i can change to override the need for a button press? i don't know where the branch in logic due to that button press occurs. Oct 22 16:36:07 thisisbrians, the button press is required to force the boot mode .. Oct 22 16:36:36 which is set in jumpers on the board (or resistors and the push switch) Oct 22 16:45:36 stt_michael: roger. thanks—i wasn't sure if it was pure hardware or not. Oct 22 16:47:55 yes, its set by the am335x processor chip .. it is configurable, but only by hardware on initial power-up Oct 22 17:49:26 given two drivers that declare the same compatible string, a single device, and the corresponding device tree, can anyone help me understand *how* the driver is bound to the device? Oct 22 17:49:51 I've got a driver that is stealing my device, and I can't figure out how to influence the driver/device binding process Oct 22 17:52:26 kaak, don't build that driver into your kernel? Oct 22 17:52:28 if you have two drivers with the same compatible string, something is already wrong Oct 22 17:52:50 drivers are unique flowers Oct 22 17:52:53 or snowflakes Oct 22 17:52:57 * bradfa can't remember which Oct 22 17:53:17 see: `drivers/tty/serial/8250/8250_omap.c`, and `drivers/tty/serial/omap-serial.c` Oct 22 17:54:12 it's driving me nuts, because in one DT/Kernel, 8250_omap steals my uarts, and in another DT/Kernel omap-serial gets it Oct 22 17:54:47 Yeah, disabling seems to be the easiest approach Oct 22 17:55:05 thisisbrians: the lcd_data 0-15 pins are sampled at power-on-reset deassertion, those values become known as sysboot 0-15 and determine various boot configuration. To set them there are 100K pull resistors on the board, though the SD boot button overrides one of them (sysboot 2) by pulling it to ground with 100 ohm if you press it Oct 22 17:55:52 thisisbrians: you can also hook up resistors externally to achieve the same effect. I do that e.g. for ethernet booting (sysboot 0 pulled high, sysboot 2 pulled low) Oct 22 17:57:14 full overview of their purpose can be found in the docs, or more conveniently in the "Boot" tab of my spreadsheet -> https://docs.google.com/spreadsheets/d/1CK5c-Cs8G1RtzGo-J3VJsD9m5K-fp06AncgeYWsdjSU/view Oct 22 17:58:14 (on a BBB, never select a boot mode that includes a 'nand' or 'xip' boot mode) Oct 22 17:58:29 eh, nand or xip boot device Oct 22 17:58:38 ERR duplicate use of word 'boot mode' ;P Oct 22 17:58:59 kaak: normally you never have both of those drivers enabled Oct 22 17:59:21 supposedly 8250_omap is the replacement of omap-serial, though I have no idea why Oct 22 17:59:44 yeah, omap-serial has the rs485 support I need Oct 22 18:00:06 so you can image my confusion when it suddenly started being stolen by this other driver Oct 22 18:00:23 I also have omap-serial enabled in my config rather than 8520_omap Oct 22 18:00:47 also, its times like this I wish someone would have put a !8520_omap in the Kconfig dependencies Oct 22 18:00:54 and vice-versa Oct 22 18:01:55 may be of some use to someone: http://events.linuxfoundation.org/sites/events/files/slides/dt_debugging.pdf Oct 22 18:01:55 well then, go forth and submit a patch Oct 22 18:02:38 can you point me to a place with docs on the process? Oct 22 18:05:35 zmatt: thanks. by "ethernet booting" what exactly do you mean? pxe? Oct 22 18:05:56 much more simplistic, it uses bootp + tftp Oct 22 18:06:15 it's convenient for baremetal applications Oct 22 18:06:42 I just recompile, reset the board, and ROM will grab the new image from my laptop Oct 22 18:09:01 kaak: have you acquired an asbestos suit yet? because that's usually considered step 1 ;-) Oct 22 18:11:10 zmatt: gotcha. i'm not too familiar with netboot...i've definitely got some homework to do. thanks for the pointer. Oct 22 18:14:52 thisisbrians: http://pastebin.com/DiHDdgjG Oct 22 18:16:10 thisisbrians: ROM will grab the designated file from the tftp dir, writing its contents to local SRAM starting at address 0x402f0400, and then jump there Oct 22 18:19:17 got it. what's the size limitation on your image? Oct 22 18:20:09 iirc little over 100 KB, would need to look it up Oct 22 18:20:51 thanks Oct 22 18:21:39 there are two consecutive 64 KB SRAMs, at 0x402f0000 and 0x40300000, so RAM end is at 0x40310000, but the first 1 KB of the first SRAM is inaccessible (hence the address 0x402f0400) and some of the memory near the end of the RAM is used by the bootloader while receiving your code Oct 22 18:25:44 of course, 127 KB is plenty of space to fit a multitasking OS with full networking stack, but u-boot doesn't even manage to fit a bootloader in there so instead it needs to be loaded using an additional intermediate stage (SPL) :P Oct 22 18:26:42 which also means that netbooting linux from scratch is complicated by the fact you'd need to manage to build an SPL that can fetch the full u-boot via TFTP Oct 22 18:31:26 the first 1 KB is reserved for use by secure ROM... it doesn't actually use it, but it reserved it anyway. Sec ROM appears dedicated to doing stupid shit like that and making the chip less useful in general Oct 22 18:34:22 Oct 22 18:37:46 "The maximum size of downloaded image is 109 KB." Oct 22 21:26:28 hello everyone! Oct 22 21:27:28 I am a newbie Oct 22 21:28:42 I want help with my BBB.

Oct 22 23:12:02 and when Oct 22 23:12:24 systemd-resolved will take care of it Oct 22 23:12:39 I don't trust Pottering ... :p Oct 22 23:12:54 and his band of Merry coders :E Oct 22 23:13:17 I Shall Not Be Assimilated !!! Oct 22 23:13:19 lol Oct 22 23:13:20 I don't know him personally, I just know it works a lot better for us than the crappy scripts it replaces Oct 22 23:14:00 if/when it works .. like all technology ..its fine .. when its broke .. I'd rather edit a text file :) Oct 22 23:14:54 mmm this tuna is good .. even if I overcooked it a bit .. :9 nom Oct 22 23:15:37 I got Android woes today .. one tablet that refuses to update .. and my bloody phone has lost sound in the phone 'app' :(( Oct 22 23:15:47 like .. WHERE IT MATTERS! Oct 22 23:15:49 actually you can also just override it in your eth0.network text file Oct 22 23:16:13 have you tried miming instead? Oct 22 23:16:24 yea ... doesn't work long0distance .. Oct 22 23:16:53 the smoke signals are ok for 'local' calls .. Oct 22 23:17:04 until the sun sets .. Oct 22 23:17:13 I need to rig up a beacon Oct 22 23:17:37 wow, systemd.network gained a lot of options since the last time I looked Oct 22 23:18:06 yea I suspect by comparison, sliced bread is very last millenium .. Oct 22 23:20:17 although, speakin of last millenium .. I still want to buy a bicycle to ride .. costs a lot less than my car .. Oct 22 23:20:38 although the range aint' quite so good Oct 22 23:20:47 * zmatt walks and uses public transport Oct 22 23:20:58 and passenger comfort is far from optimal if the weather is inclement Oct 22 23:21:42 I do walk occasionally .. about three/four times a year :) Oct 22 23:21:48 woohoo :P Oct 22 23:22:30 yea don't wanna get carried away lol Oct 22 23:22:38 or .. such ..lol Oct 22 23:24:07 * zmatt likes being able to choose his own hours Oct 22 23:25:16 being in the office when noone is around is excellent, I turn up the volume on music, nobody's hoarding the scope if I need it, no infernal CNC machine making a sound that makes your brains dribble out of your ears Oct 22 23:27:42 amen to that Oct 22 23:27:46 aLL of that ! Oct 22 23:28:25 we have 5 Oct 22 23:28:34 CNC machines? Oct 22 23:28:38 varying pitches of brain dribbling Oct 22 23:28:39 /o\ Oct 22 23:28:43 4 mills and 2 lathes Oct 22 23:28:46 * zmatt flees in horror Oct 22 23:28:46 6 then. Oct 22 23:29:17 yea working at night is bliss Oct 22 23:29:59 unless someone randomly decides to Dyno an engine ... although .. tbh thats nothing against cnc bearing/spindle whine .. Oct 22 23:30:06 plus, it's always a surprise what kind of weird stuff I'll find when I get here Oct 22 23:30:51 like "yeah, we can borrow a mixer console" ... I thought it was going to take up some of my desk space... but no, http://gerbil.xs4all.nl/werk/2012-09-27-0115-0977.jpg Oct 22 23:31:27 damn that's a Beast Oct 22 23:32:04 20-channel frame is about my biggest Oct 22 23:32:15 usually only about 12 are populated Oct 22 23:32:38 or 16. Oct 22 23:32:40 thereabouts Oct 22 23:32:47 finding this was also funny -> http://gerbil.xs4all.nl/werk/2013-11-12-0416-1823.jpg Oct 22 23:32:58 12 is a couple too-few Oct 22 23:33:08 damn, can't believe how empty the place was back then Oct 22 23:33:36 nice rig .. the right hand cones don't look quite right somehow though ... Oct 22 23:33:56 they're jsut a bunch of random prototypes stacked for fun Oct 22 23:34:04 far do's Oct 22 23:34:07 fair* Oct 22 23:34:39 the monitor in the middle-top is the one I still use for my music though... doesn't need a separate sub, it does a fine job on its own Oct 22 23:34:41 my boss appears to have taken up the new development area for audio purposes .. Oct 22 23:35:09 got his crazy pipe-based floor standers in there Oct 22 23:35:19 I've yet to hear them actually .. supposed to be quite good Oct 22 23:37:45 http://www.linkwitzlab.com/Pluto/Pluto-2.1.htm Oct 22 23:38:18 ah, and there's that pic I was looking for of when I was doing pmic testing... the poor thing looked like it was on an intensive care unit or something -> http://gerbil.xs4all.nl/werk/bbb-pmic-testing.jpg Oct 22 23:39:07 linkwitz, there's a name Oct 22 23:39:42 indeed Oct 22 23:40:05 our speakers are briefly mentioned somewhere on that site too I think Oct 22 23:40:25 life support beagle .. Oct 22 23:41:30 http://www.linkwitzlab.com/Constant_directivity_louds.htm#Commercial second one from the top Oct 22 23:41:46 (you have to admit, our pics look better than their Meier's frequency plot) Oct 22 23:41:52 s/their // Oct 22 23:42:23 shit .. had I know that when I Was out in CA >. I was just down the road .. or up as it happens .. Oct 22 23:42:59 CA ? Oct 22 23:43:01 dutch + dutch ? Oct 22 23:43:03 california Oct 22 23:43:10 we're in the Netherlands Oct 22 23:43:32 yea I was pickin up a dutch flavour ... ;P Oct 22 23:43:37 hehe Oct 22 23:43:58 <= SW England currently Oct 22 23:44:14 another of the European crows Oct 22 23:44:17 crowd* Oct 22 23:44:23 jees .. can't trypo Oct 22 23:44:29 in a hick town that will make customs go "you're going where? ... ... *why* ? o.O " Oct 22 23:44:45 in the sticks .. Oct 22 23:44:52 heh nice Oct 22 23:45:16 friend of mine spent some time out there Oct 22 23:46:40 the place has also gotten much nicer since that pic... not just bare concrete anymore, the listening area has a carpet, and a couch Oct 22 23:47:39 that helps .. keeps the echo and room reverb down Oct 22 23:48:00 furniture discourages resonances Oct 22 23:48:06 yes, a giant concrete hall is somehow not entirely optimal for acoustics Oct 22 23:48:19 you got an anechoic chamber stashed somewhere? Oct 22 23:48:22 those are funky Oct 22 23:48:26 no. been in one though Oct 22 23:48:28 they are indeed Oct 22 23:48:40 yeah I never had the door shut on the one I went to Oct 22 23:48:42 standing on a net suspended in the air... *bounce bounce* Oct 22 23:48:48 yip yip Oct 22 23:49:03 I had Oct 22 23:49:24 they say you can't hear someone talking next to you .. if they face away .. Oct 22 23:50:04 I don't think we emit sound with such high directivity Oct 22 23:50:18 I've done a fair bit of work in radio/microwave chambers .. emc and radio propagation testing Oct 22 23:50:25 no .. true .. Oct 22 23:52:14 so where does the beaglebone fall into this crazy world then? Oct 22 23:52:18 fall/fit Oct 22 23:53:19 its sadly lacking in audio hardware out-of-the-box .. Oct 22 23:53:37 but it has spi to control the dsp Oct 22 23:53:52 iirc the mcasp pins are muxed with the bloody hdmi rgb data pins Oct 22 23:53:59 no Oct 22 23:54:07 or is there another set .. Oct 22 23:54:08 mcasp pins are used for hdmi audio Oct 22 23:54:14 d'oh right Oct 22 23:54:15 but we don't use hdmi anyway Oct 22 23:54:20 no .. nasty thing Oct 22 23:54:27 esp. on that silly micro connector Oct 22 23:54:31 actually the framer seems quite nice Oct 22 23:54:40 μHDMI is indeed an iffy connector Oct 22 23:54:41 it does its job .. Oct 22 23:55:00 I noticed there aren't as many red & blue pins as green .. Oct 22 23:55:09 565, that's normal 16-bit color Oct 22 23:55:17 we're more sensitive in green Oct 22 23:55:18 ah 24bit is 666 Oct 22 23:55:21 888 Oct 22 23:55:26 damnit yup Oct 22 23:55:26 666 is 18-bit :P Oct 22 23:55:42 I woke at 4:45 .. its gettin late :p Oct 22 23:55:47 am! Oct 22 23:56:00 but why would you do such a thing? Oct 22 23:56:02 ;) Oct 22 23:56:12 because. Oct 22 23:56:50 my head starting into a bash script project a friend has been working on .. and then some other random crap I really didn't want to think about at 5am .. Oct 22 23:57:06 oh boy, a bash script project Oct 22 23:57:10 by5:20 I was outta bed .. Oct 22 23:57:22 ideally a bash script should never be a project Oct 22 23:57:44 by the time it is one, something other than bash scripting has probably become more relevant Oct 22 23:57:46 its "only" a monitoring script really .. but its grown in scope Oct 22 23:57:49 *more appropriate Oct 22 23:57:52 yeah that Oct 22 23:58:09 and now it needs smashiing in two Oct 22 23:58:22 runs from cron Oct 22 23:58:30 proper smashing is always into at least three pieces Oct 22 23:58:35 oh definitely Oct 22 23:58:44 this is token gesture :) Oct 22 23:59:00 two is more like, splitting a candy bar for sharing Oct 22 23:59:06 or 'bisection' if you're bein pedantic :p Oct 22 23:59:46 I still miss our original dm814x-based board though Oct 23 00:00:16 well, not really missing it, it's still right in front of me and processing my music, but Oct 23 00:00:30 as a project it's pretty dead :/ Oct 23 00:06:12 what ya got the dsp's doing? Oct 23 00:06:37 I've just discovered why my boss wanted a new dsp board I ordered this week .. lol Oct 23 00:06:48 think he's 'tuning' his crossover Oct 23 00:09:15 crossover, flattening the response, some protection against people intent on blowing the thing up :P the usuals Oct 23 00:10:29 I already explained that the only proper way to deal with a clipping indication is by sending some feedback signal to the mixer console and have little mechanical hand pop out and slap the operator Oct 23 00:30:13 either that or compression or hard limiting .. but that gets a bit nasty except on loud events where its not noticeable Oct 23 00:30:56 right but then you're compromising the audio quality of your speaker... but you really have no choice, since it's really too late to do anything about it Oct 23 00:30:59 limiters are a good idea whenever morons get involved Oct 23 00:31:03 hence the little hand to slap the operator Oct 23 00:31:06 precisely Oct 23 00:31:44 you're merely exerting damage limitation or elimination, hopefully .. at an audible cost Oct 23 00:32:02 unfortunately, morons just.. are. Oct 23 00:32:18 and anyone who cares will notice .. Oct 23 00:32:31 most will hopefully be too drunk though Oct 23 00:32:39 true Oct 23 00:32:47 and that's not always entirely a bad thing Oct 23 00:32:53 it makes for an easier night Oct 23 00:33:00 or day/etc Oct 23 00:33:42 its quite fun to have all the options though Oct 23 00:33:56 I mean, I recently heard something about a scanner or moving head that managed to get soaked in champagne, so, well... Oct 23 00:34:06 *cringe* Oct 23 00:34:15 hazards of the job though Oct 23 00:34:24 yeah, glad it's not mine though Oct 23 00:34:41 even my effects have a thin film of effect smoke .. except maybe one or two Oct 23 00:34:58 I think that's the best way though .. proves they've actually been *used* lol Oct 23 00:35:21 which reminds me .. need to re0engineer a new remote for the smoke machine .. and get some fluid Oct 23 00:36:13 hmm .. my mind was wondering into the realms of subwoofers again .. -sigh- Oct 23 00:36:33 seen the specs on our sub btw? :) https://dutchdutch.com/professional/pro-fidelity-s18c Oct 23 00:37:54 And I got a control board that doesn't fire its main lamp :( hmm .. need to get that out and test it .. Oct 23 00:37:57 sec .. Oct 23 00:38:21 yeeesss ... I don't think I could get INTO my lounge with that though ... lol Oct 23 00:38:36 hehe Oct 23 00:38:38 it would teach my neighbour a lesson or two though *snicker* Oct 23 00:38:59 I liked the comments about the tweeter in that PLUTO .. let me find it again .. Oct 23 00:39:32 these things are really unfunny loud Oct 23 00:40:08 .. here we go .. "Occasional clicks during high peak sounds. This is an indication that the woofer power amplifier is clipping. It generates high frequency spectral components which are radiated by the woofer as clicks. The higher frequency spectrum from the tweeter remains clean as ever. I have never observed the tweeter power amplifier clipping.... Oct 23 00:40:19 . There is no need to turn down the volume, other than for complaints from your neighbors." Oct 23 00:40:35 *grin* Oct 23 00:40:47 or your ears exploding lol Oct 23 00:40:58 I think that's typical though, tweeters being much more efficient Oct 23 00:41:20 yes enormously so .. and the sheer volume of air you need to shift for loud bass frequencies Oct 23 00:41:29 uhuh Oct 23 00:41:54 although .. it you properly consider these factors .. its all do-able Oct 23 00:42:03 the only true winner there is the rotary woofer... it has flat response down to 0 Hz. If you input a DC signal, the air pressure in the room changes slightly Oct 23 00:42:16 oh? Oct 23 00:42:28 I've heard about these servo drive(rs) Oct 23 00:42:32 it's basically a fan with blades that can be modulated Oct 23 00:42:44 mounted in a wall or something Oct 23 00:42:45 ah I wondered once about something like that Oct 23 00:43:00 http://www.rotarywoofer.com/model17impedance.html Oct 23 00:44:06 yours for only about $22,000 - $26,000 Oct 23 00:44:31 includes custom design, installation, performance testing, etc though Oct 23 00:46:17 one may experience some issues with rattling doors and such though, especially below 5 Hz :P Oct 23 00:46:39 you can't *hear* those frequencies lolol .. Oct 23 00:46:48 you can hear the rattling doors though Oct 23 00:46:53 you can get those going into the few tens of herz .. Oct 23 00:46:54 hehe Oct 23 00:46:59 yes .. alas .. Oct 23 00:47:36 although if you wedge them appropriately .. they'll just vibrate Oct 23 00:47:44 better still .. take them off :D Oct 23 00:48:07 well it obviously needs an adequately enclosed space Oct 23 00:48:09 though .. that might have unwanted side-effects ... :) Oct 23 00:48:58 wow, it's quite efficient too Oct 23 00:48:59 its an interesting concept .. because fundamentally, they're right .. you have to throw away the voice-coil 'mover' Oct 23 00:49:18 yeah .. only thing already comparable I suppose is a bass horn (which do exist ..) Oct 23 00:49:30 you need insane horns though Oct 23 00:49:50 horns are quite cool .. but much more manageable at microwave frequencies :D Oct 23 00:49:55 yes Oct 23 00:50:13 in general, you have problems when trying to radiate waves bigger than you are Oct 23 00:50:28 why do we have such an inconvenient hearing/sensing range?! Oct 23 00:50:42 I suppose it must have something to do with our surroundings Oct 23 00:50:44 because at higher frequencies, air becomes a really shitty transmission medium Oct 23 00:50:56 dispersive, non-linear crap Oct 23 00:51:03 yeah .. but our ears don't work so well under water :/ Oct 23 00:51:09 we don't live under water Oct 23 00:51:18 there is that too Oct 23 00:51:21 makes breathing hard Oct 23 00:51:35 our ears make the most of the range that's usable Oct 23 00:51:49 they;re bloody amazing .. like most of our senses .. Oct 23 00:51:51 lol Oct 23 00:51:55 broadening the spectrum would be useless, hence they're so frigging sensitive instead Oct 23 00:52:37 which is why noise is a bigger problem than in almost any other kind of transmission Oct 23 00:53:05 way too much data packed into way too little bandwidth :/ Oct 23 00:53:31 ah that depends on the encoding *ahem* source :p Oct 23 00:54:00 and whether you choose to try to 'tune' it .. but its true .. its exhausting for long periods of time Oct 23 00:54:18 take aircraft for example... ugh. Oct 23 00:54:50 I'm not talking about the artifects caused by digital compression though, I mean once it enters the analog domain, which unfortunately it still needs to do eventually Oct 23 00:55:08 yes we only have an analogue interface .. Oct 23 00:55:31 and I doubt there is likely ever to be a way of accessing the brain's encoding methods Oct 23 00:55:50 whether they're analogue or digital Oct 23 00:56:28 no .. lets not start on digital compression .. and them artifects :/ Oct 23 00:56:33 actually, there are already implants for people who have lost their hearing, not really sure how they work though Oct 23 00:57:01 I think you still ccreate some form of movement/vibration don't you? Oct 23 00:57:04 its just highly localised Oct 23 00:57:29 "An electrode array, which is a group of electrodes that collects the impulses from the stimulator and sends them to different regions of the auditory nerve." Oct 23 00:57:33 and proportionally high intensity? very crude if so. Oct 23 00:57:54 ah so it does attempt some stimulation of the nerve Oct 23 00:58:01 Cochlear implants bypass damaged portions of the ear and directly stimulate the auditory nerve. Signals generated by the implant are sent by way of the auditory nerve to the brain, which recognizes the signals as sound. Hearing through a cochlear implant is different from normal hearing and takes time to learn or relearn. Oct 23 00:58:53 how does it stimulate the nerve .. I assume that's all downstream of them tiny bones & structures... Oct 23 00:59:14 go forth and google yourself? :P Oct 23 00:59:22 eh too lazy :D Oct 23 01:00:43 tis awesome stuff though Oct 23 01:03:08 oi, my music stream died Oct 23 01:09:11 :\ Oct 23 01:09:41 it's back Oct 23 01:10:36 \o/ Oct 23 01:14:31 yay, vayu's control module stores the MAC address in... yet another format different from the other two already in use by the ethernet switch subsystem \o/ Oct 23 01:14:46 how many ways can you invent to store 6 fucking bytes Oct 23 01:14:52 (don't answer that) Oct 23 01:15:31 I could tell you a tale about a certain vendor 's ONVIF implementation which is ... well .. spaghetti would be putting it mildly .. Oct 23 01:18:42 the most commonly used byteorder I've seen on TI chips is { b4, b5, -, -, b0, b1, b2, b3 } Oct 23 01:19:11 used e.g. by centaurus and subarctic control module, and by the MII module Oct 23 01:20:04 the switch table entries use { b1, b0, xx, yy, b5, b4, b3, b2 } Oct 23 01:20:07 where xx/yy is other stuff Oct 23 01:20:43 vayu's control module uses { b5, b4, b3, -, b2, b1, b0, - } Oct 23 01:21:20 nobody considered just storing the 6 bytes in the order actually used in packets Oct 23 01:24:15 most of the crap seems to be due to various kinds of endian swapping, all of which is misguided since 1. a MAC address isn't an 48-bit number but six bytes 2. unlike higher-level protocols, ethernet is actually little-endian. In particular, the multicast ("group") bit is bit 0 of byte 0, the very first bit sent on the wire when serialized Oct 23 01:24:45 -.- Oct 23 01:37:20 * zmatt feels conflicted Oct 23 01:38:15 I have a strong urge to renumber things like peripherals to be consistently zero-based, rather than the mix of 0- and 1-based the TRM uses Oct 23 01:38:43 but in vayu's case that's quite a lot of renumbering Oct 23 01:39:06 otoh if i'm gonna do it, I'd better do it now when it's still easy to ensure at least my own documentation is internally consistent Oct 23 01:39:13 hmz Oct 23 01:42:03 heh Oct 23 01:43:12 bizarrely, it uses 0-based numbering for one of the few things where subarctic uses 1-based: the ethernet interfaces Oct 23 01:46:09 hey, can you tell me if the gst-ducati plugin is availeble for the bb xM? Oct 23 01:55:56 https://gitlab.com/gstreamer-omap/gst-ducati ? Oct 23 01:56:12 that's omap4 .. Oct 23 02:02:22 so the answer is no :D Oct 23 02:03:11 uavcamm, "ducati" is ip on the omap4.. if you want dsp video, find 2.6.32 and the original angstrom image.. Oct 23 02:08:06 thanks rcn. will try to find it. Oct 23 02:17:16 if you want hw accelerated video .. get a RPi *cough* Oct 23 02:17:46 no, get a x15 ;) Oct 23 02:19:20 good luck with that :p Oct 23 02:19:57 anyhoo .. I'ma go sleep before I keel over .. nite all! I-) thanks for the chat zmatt and happy coding :P Oct 23 02:32:33 veremit`afk: nite! Oct 23 02:42:32 it is done. Oct 23 02:42:40 my spreadsheet is now fully 0-based Oct 23 02:52:38 rcn-ee: have you seen the progress on my vayu pins spreadsheet? :) Oct 23 02:54:34 I'm considering hiding the boundary scan and power domain columns for now, since nobody will care anyway Oct 23 02:55:41 hi guys, I'm having some trouble with a cape. I almost never ask for support since I usually find what I need already in the mailing lists. This one got me really stumped though Oct 23 02:56:17 I have the output of things of intest in a pastebin, but where is the best place to ask for help? is there a dedicated mailing list? Oct 23 02:56:54 matthewaveryusa: in here is ok too, try paste and see if anyone knows Oct 23 02:57:18 there are mailing lists, which you already know since you usually find what you need in them :P and you found this place, so I'd say give it a spin **** ENDING LOGGING AT Fri Oct 23 02:59:58 2015
