**** BEGIN LOGGING AT Tue Jun 18 02:59:59 2013 Jun 18 03:01:12 dgriffi: I guess that one does clear, but most seem to extend further. anyway, I've never seen a case with an arrangement for extending the on-board switches. IIRC, the black is different than the white wrt to those switches, which further reduces the niche Jun 18 03:14:02 Hmmmm Jun 18 03:17:02 Mhhhh Jun 18 03:21:10 beer! Jun 18 03:21:28 actually not but felt the channel needed thta Jun 18 03:23:45 what the channel needs is a good troll bridge. Have you seen the bridge? Jun 18 03:26:57 martinm: here's one with buttons: http://www.thingiverse.com/thing:82363 Jun 18 03:27:36 another thing I'm looking for is something that'll be good with a cape on top. I'm trying to build a ham radio repeater controller cape Jun 18 03:28:42 there this one: http://www.logicsupply.com/blog/2013/05/23/beaglebone/, but those big gaps that appear when you configure it for having a cape are a non-starter for me Jun 18 03:29:03 I guess buttons aren't that much of a concern Jun 18 03:30:01 you don't really need the boot button, anyway... a properly setup SD card will Just Boot if present at startup Jun 18 03:30:25 I plan to ignore the onboard mmc Jun 18 03:30:46 in fact even if you don't wish to boot from the SD card there are some requirements on how its setup Jun 18 03:31:57 what I need for a repeater controller is something that'll house the bbb with a cape and have a DE9 / DE15 cutout Jun 18 03:34:41 this thread has a most illuminating discussion of things no one else bothers to mention about how the black boots, including the magic three-line config file to boot on eMMC which allows you to mount the SD for setting it up, etc. https://groups.google.com/forum/#!topic/beagleboard/lEMH0rvm6Ys Jun 18 03:35:28 martinm: we could start a troll bridge fund but i think the bradfa camera fund should come first Jun 18 03:35:37 speaking of which, I need to bookmark that before I lose track of it Jun 18 03:36:13 we need steenking cameras? Jun 18 03:40:38 martinm: i don't think bradfa is ready for a iphone Jun 18 05:29:28 [kernel] koenkooi pushed 2 new commits to 3.8: http://git.io/aQVmMA Jun 18 05:29:28 kernel/3.8 2798aae Koen Kooi: 3.8: add RS232 cape support... Jun 18 05:29:28 kernel/3.8 b379285 Koen Kooi: 3.8: fix segfaults on boot when compiled with gcc 4.8... Jun 18 05:29:55 jackmitchell1: that last commit is for you :) Jun 18 05:30:17 ka6sox-away: congrats! Jun 18 05:33:03 koen, tyvm :) Jun 18 05:39:19 evil koen is here! Jun 18 05:45:38 omg, I think I did mistake on my BBB :'( Jun 18 05:46:17 it doesn't even show on the device manager Jun 18 05:46:27 any help? Jun 18 05:47:40 get a new one Jun 18 05:49:01 omg: what kind of mistake? Jun 18 05:49:08 omg: did you let out the magic smoke? Jun 18 05:49:20 oh... and JIHAD! Jun 18 05:49:30 I was trying to disable HDMI so that I can use an audio cape. Jun 18 05:49:48 and? Jun 18 05:49:56 what did you do? use a soldering iron? Jun 18 05:50:08 smash it with a sledgehammer? Jun 18 05:50:41 drown it in the lake with concrete shoes? Jun 18 05:51:28 anybody who can help me seriously? Jun 18 05:51:47 not unless you tell us what you did Jun 18 05:52:01 if you dont speak, others do :) Jun 18 05:52:12 and i speak a lot when the day is long Jun 18 05:52:13 :) Jun 18 05:52:44 okay, follows are what I did~ Jun 18 05:52:53 1. mount /dev/mmcblk0p1 /mnt/card Jun 18 05:52:59 2. cd /mnt/card Jun 18 05:53:18 3. edit uEnv.txt with -> optargs=quiet drm.debug=7 capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN,BB-BONE-EMMC-2G capemgr.enable_partno=BB-BONE-AUDI-01 Jun 18 05:53:26 4. unmount and rebooting Jun 18 05:54:24 if it's just that.... Jun 18 05:54:42 mount the sd card, return the uboot options back to what they were Jun 18 05:55:20 I am beginner of Linux Jun 18 05:55:53 if I don't have any connection with neither HDMI nor ssh, Jun 18 05:56:05 how I can mount it? Jun 18 05:56:14 omg: if you get lost in a forsest, what do you do? run around in circles shouting that you don't know where you are? or try to retrack your steps back from where you came? Jun 18 05:56:31 07:52 < omg> 1. mount /dev/mmcblk0p1 /mnt/card Jun 18 05:56:48 I don't have any terminal to access it Jun 18 05:56:55 put it into your pc Jun 18 05:57:08 oh.. you dont have a serial adapter for the bbb? Jun 18 05:57:21 no I don't have Jun 18 05:57:25 rotfl Jun 18 05:57:29 sorry, but that's funny Jun 18 05:57:30 you mean RS2232? Jun 18 05:57:44 you know, if you disable hdmi, you will _not_ have any output on the monitor anymore Jun 18 05:57:49 because you disabled the monitor Jun 18 05:58:03 yes, i mean rs232 Jun 18 05:58:17 but I could still connect to the board through usb connection by using SSH Jun 18 05:58:28 true that Jun 18 05:59:14 now I also lost it with what I typed. Jun 18 05:59:14 but without a serial cable, you cannot tell why the network connection doesnt come up Jun 18 05:59:57 jkridner_: could you put something like "if you have problems, get a serial cable" into the topic? Jun 18 06:01:20 does Jtag would work for it? Jun 18 06:01:41 jtag is something completely different Jun 18 06:01:49 yes, you could use it as a console, but nobody does Jun 18 06:02:16 and i dont know how to configure linux to output stuff on jtag for that purpose Jun 18 06:02:34 just get one of the serial cables Jun 18 06:02:46 those things cost 5 bucks, and you will need one anyways Jun 18 06:03:08 KotH: JIHAD! Jun 18 06:03:16 mranostay: BEER! Jun 18 06:03:21 FRIDAY! Jun 18 06:03:24 I have a rs232 cable but connector doesn't fit for BBB. may be it is different one. Jun 18 06:03:37 koen: you *** it isn't friday Jun 18 06:03:45 mranostay: it is friday! Jun 18 06:03:53 * mranostay sobs at being another year older on friday Jun 18 06:04:02 mranostay: somewhere in the world it is friday! dont you know your timezones? Jun 18 06:04:14 poor mranostay Jun 18 06:04:26 getting of age slowly, are we? Jun 18 06:04:37 KotH: same rate as you Jun 18 06:05:00 * emeb_mac sobs at being another minute older now Jun 18 06:05:29 but not much Jun 18 06:05:45 emeb_mac: you are much closer to death than me at least :P Jun 18 06:05:53 in theory Jun 18 06:06:02 mranostay: sad but true. Jun 18 06:06:24 mranostay: I can use a friday right now Jun 18 06:06:38 fridays for everyone! Jun 18 06:06:42 * mranostay puts on the metallica Jun 18 06:06:43 emeb_mac: if you live a good life, stay away from alcohol, drugs and women, you will live very old Jun 18 06:06:54 av500: call an emergency friday! Jun 18 06:06:59 you won't live forever, but it will feel like it? Jun 18 06:07:10 juup Jun 18 06:07:29 KotH: i don't do the middle one so what are my chances? :) Jun 18 06:07:47 KotH: the ship has sailed on all three of those types of abstinence. Jun 18 06:07:49 of course alcohol is a drug.. :) Jun 18 06:08:05 * mranostay loved his grandma that wouldn't call alcohol a drug ) Jun 18 06:08:06 :) Jun 18 06:08:30 ah 1930's logic :) Jun 18 06:09:22 i think, you could subscribe to the russian logic that vodka is like water Jun 18 06:09:28 one of my grandpas was a teetotaler - lived to 99. Jun 18 06:10:26 (the plural of anecdote is not data) Jun 18 06:11:05 mranostay: http://en.wikipedia.org/wiki/File:The_Drunkard%27s_Progress_-_Color.jpg Jun 18 06:11:14 emeb_mac: not drinking is best but meh :) Jun 18 06:11:37 KotH: Thank you for your advice! Jun 18 06:12:04 omg: np... always here to troll Jun 18 06:12:38 KotH: 5 is what i want to shoot for so to speak right? Jun 18 06:13:03 juup Jun 18 06:13:10 you cannot drink alone! Jun 18 06:13:27 drink yes Jun 18 06:13:29 drunk no Jun 18 06:14:43 hmm does ACPI tables in linux get walked for every lookup?... Jun 18 06:16:07 that's a question, only a drunk mind could ask Jun 18 06:16:09 ;) Jun 18 06:18:03 KotH: bite me i'm sober :P Jun 18 06:21:11 * mranostay thinks that would be good indie song Jun 18 06:23:58 mranostay: would electrocution count as biting as well? Jun 18 06:25:21 KotH: can we all get along? Jun 18 06:25:28 probably not Jun 18 06:26:07 only over some dead bodies Jun 18 06:27:13 omg: if all else fails, just reflash it Jun 18 06:27:17 greek people first please Jun 18 06:27:27 and then the serbs :P Jun 18 06:27:30 ofc Jun 18 06:27:39 first greek, then serbs, then the usians Jun 18 06:28:22 why not the canucks too? Jun 18 06:28:33 they are friendly Jun 18 06:29:01 it is an act Jun 18 06:31:01 they are still good at it Jun 18 06:31:23 KotH: to be fair we haven't bombed turkey ever :P Jun 18 06:31:55 you wont Jun 18 06:31:56 mranostay: as a matter of fact, you did Jun 18 06:32:00 mranostay: multiple times Jun 18 06:32:08 lalalalala Jun 18 06:32:24 in the last 50 years :P Jun 18 06:32:30 juup Jun 18 06:33:15 in '91, dozens of your bombs and cruise missiles went down on turkish soil, killing people Jun 18 06:33:51 that was metric vs imperial Jun 18 06:33:53 in the second gulf war, you occupied the port of iskenderun to force the turkish gov to let your army pass trough turkey Jun 18 06:33:55 happens to the best Jun 18 06:34:07 for over a week Jun 18 06:34:33 whats a week between friends Jun 18 06:35:10 well... due to a stupid guy who thought he could force is way out of the cordoned of port, it nearly came to a fight Jun 18 06:35:49 which would probabyl would have ment war Jun 18 06:35:54 <_Sy_> Good morning Jun 18 06:36:01 KotH: ah cmon Jun 18 06:36:35 i think we could all use a hug and some kumbaya Jun 18 06:36:45 <_Sy_> :) Jun 18 06:37:25 * emeb_mac would rather have beer Jun 18 06:37:26 mranostay: it would be enough if the us wouldnt meddle with other peoples lifes Jun 18 06:37:48 boy is that totally missing the point. Jun 18 06:37:49 mranostay: there is a reason, why the usians aren't liked very much in the gulf area Jun 18 06:38:04 <_Sy_> Is there a CAPE for the beaglebone BLACK that adds a high resolution crystal and battery backup? I'm looking for something that would reduce clock drift to a minimum whilst keeping the clock during power dips. Jun 18 06:38:18 emeb_mac: hug + kumbaya + beer = awesome Jun 18 06:38:34 _Sy_: add something like ntp Jun 18 06:38:37 _Sy_: works better Jun 18 06:38:38 mranostay: beer + hug. skip the kumbaya. Jun 18 06:39:03 <_Sy_> I have NTP, but the issue is when the network isn't avaiilable and the power goes....then everything goes to pot. Jun 18 06:39:23 KotH: emeb_mac: _Sy_: ok group hug! Jun 18 06:39:27 _Sy_: use one master and sync all others to that one Jun 18 06:39:30 so you complain that when you lose power, you have no more NTP? Jun 18 06:39:51 <_Sy_> The question is what to sync to, if like I have now no broadband, then no NTP. Jun 18 06:40:00 so Jun 18 06:40:05 the clock still runs, no? Jun 18 06:40:05 _Sy_: it's a common mistake to think that you need accurate time and sync all ntp clients to an external server, while all you need is to have the same time on all clients Jun 18 06:40:39 <_Sy_> What I want is a reliable time keeping method, so once the time is known it keeps it and doesn't drift much....possible with good crystals...and battery backup, just wondered if there is already a CAPE to do this. Jun 18 06:40:52 heh Jun 18 06:40:54 how does a PC do it? Jun 18 06:41:01 what you need microsecond sync for? Jun 18 06:41:02 what is "not much" for you? Jun 18 06:41:10 <_Sy_> A PC doesn't the crystals are rubbish, drifts all the time. Jun 18 06:41:29 hook up a GPS then Jun 18 06:41:33 yeah Jun 18 06:41:38 they have nucular clocks Jun 18 06:41:38 <_Sy_> Don't need micro-second, GPS 1PPS would be fine. Jun 18 06:41:41 go on ebay, buy a trimble thunderbolt Jun 18 06:42:06 <_Sy_> So no CAPE with GPS receiver on? Jun 18 06:42:10 not yet Jun 18 06:42:22 dont need a cape Jun 18 06:42:29 just hook serial RX up Jun 18 06:42:40 beside, you know that a crystal of the stability you would want costs multiple times what the bbb costs? Jun 18 06:42:41 or use USB Jun 18 06:42:49 <_Sy_> ok, I have a blue tooth GPS receiver, might give that a go. @av500, the reason I ask is I'm trying to avoid reinventing the wheel. Jun 18 06:42:49 KotH: why not a cheap GPS Jun 18 06:42:57 just get the GPS time Jun 18 06:43:01 av500: what when you lose gps reception? Jun 18 06:43:03 should be fine for most things Jun 18 06:43:12 KotH: then you run tick tock the CPU clock Jun 18 06:43:20 or a DS1307 Jun 18 06:43:24 as long as you don't live in apartment with metalized windows Jun 18 06:43:25 but the bbb crystal is rubish! Jun 18 06:43:27 <_Sy_> GBS time itself isn't very accurate, however the 1PPS time available from GPS is. Jun 18 06:43:39 rotfl Jun 18 06:43:45 _Sy_: so wrong, so wrong Jun 18 06:43:57 GPS time isn't accurate? Jun 18 06:44:11 you know how GPS works right? :) Jun 18 06:44:13 nope - US Gov't conspiracy. Jun 18 06:44:20 <_Sy_> @KotH, why? We use the 1PPS at work to keep sync. between two units then correlate the data as its 1ms accurate. Jun 18 06:44:23 if you are really quiet at night, you can hear the GPS 1PPS pulse humming in the sky Jun 18 06:44:31 * emeb_mac looks for his tinfoil... Jun 18 06:44:47 emeb_mac: prism has you wiretapped won't help Jun 18 06:45:02 <_Sy_> I know a lot about GPS, use to work for a software company that wrote navigation software for the offshore industry. Jun 18 06:45:02 mranostay: D'oh! Jun 18 06:45:11 to NSA "this man has a bomb" -> emeb_mac Jun 18 06:45:20 _Sy_: because the pps is derived from gps time Jun 18 06:45:27 <_Sy_> GPS isn't very accurate, its better than it use to be since the US turned of SA. Jun 18 06:45:46 what you have your own personaly atomic clock? :P Jun 18 06:46:09 _Sy_: gps is more accurate than you think Jun 18 06:46:16 <_Sy_> 1PPS and time in GPS message are not the same. The 1PPS is on the rising edge of the next second reported by the GPS message, so its very accurate. Jun 18 06:46:41 _Sy_: USNO somwhat guarantees that gps time tracks UTC(NIST) with an uncertanty of 100ns Jun 18 06:47:02 _Sy_: a good timing receiver with a good antenna can give you an uncertainty less than 10ns Jun 18 06:47:20 <_Sy_> Depends what documentation you read, some rase raising edge of next second, some save previous second....but the lag factor is when you recieve the GPS message itself on the serial connection. Jun 18 06:47:24 US Navy can't be trusted since they stopped using ALL CAPS Jun 18 06:47:27 _Sy_: if you have a dual band receiver, you get even blow that Jun 18 06:47:36 emeb_mac: CAPS FOREVER! Jun 18 06:47:39 STOP Jun 18 06:48:02 <_Sy_> Not all GPS receivers support 1PPS. Jun 18 06:48:08 <_Sy_> or provide it Jun 18 06:48:20 collaborate and listen Jun 18 06:48:32 _Sy_: if you want a timing output of gps, you use a timing receiver Jun 18 06:48:37 <_Sy_> But perhaps as you say I don't need to be that accurate, if all systems are synchronised to one clock source Jun 18 06:48:43 _Sy_: navigation receivers have more jitter Jun 18 06:48:45 any decent GPS module has PPS Jun 18 06:48:53 <_Sy_> I'm trying to rule out a single point of failure. Jun 18 06:49:06 mranostay: actually, all modern ones do Jun 18 06:49:18 mranostay: it's just whether the device connects it to a pin or not Jun 18 06:49:35 KotH: pretty much all do that i've seen Jun 18 06:49:45 juup Jun 18 06:50:43 guys, any comments on this one: http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,400,836&Prod=ATLYS&CFID=1888926&CFTOKEN=64824557 ? Jun 18 06:51:30 _Sy_: for all practical purposes, if you do not need a global timestamp and you can assume that you have internet connection for >95% of the time, then ntp is good enough Jun 18 06:52:00 <_Sy_> another question....I have systemd startup config for a service set to start up "After" ntpdate.service, is this going to start the second service after ntpdate gets an update or as soon as it starts running? Is it possible to wait until it gets an update before starting the next service? Jun 18 06:52:17 _Sy_: lol Jun 18 06:52:24 lol? Jun 18 06:52:27 _Sy_: you dont want to use ntpdate if you want an accurate time Jun 18 06:52:29 _Sy_: use ntpd Jun 18 06:52:40 still ntp Jun 18 06:52:44 <_Sy_> @KotH, the only reason I ask is from recent experience, my network has been down whilst the engineers sort it and its brought up a few issues. Jun 18 06:53:07 <_Sy_> I thought ntpdate was the service for ntpd ? Jun 18 06:53:09 _Sy_: I guess you can always write a systemd module that will wait for NTP time to complete Jun 18 06:53:17 and you can trigger your service after that Jun 18 06:53:24 av500: yes, but ntpdate does only a single correction, with a step. while ntpd keeps records on how much off the local clock is, and corrects for it Jun 18 06:53:43 av500: helps you keep your time to better than a couple ms/day even w/o inet connection Jun 18 06:53:51 <_Sy_> ok, I need to do some research on it. Jun 18 06:54:23 <_Sy_> brb, going to get coffee. Jun 18 06:54:49 http://serverfault.com/questions/16467/compare-ntpd-and-ntpdate Jun 18 06:54:53 _Sy_: ^^^ Jun 18 06:55:57 <_Sy_> ty, will read Jun 18 06:57:32 _Sy_: the next step after ntpd would be to run the bbb in an environment with stable temperature. keep it at the same temp better than 1°C and you get to less than 1us drift/day Jun 18 06:57:59 <_Sy_> ty, all good to know.... Jun 18 06:58:35 <_Sy_> got two 32gb micro USB sticks coming today...can't believe how little they cost. Jun 18 06:59:16 http://www.maximintegrated.com/datasheet/index.mvp/id/4627 Jun 18 06:59:34 I know, its Maxim :) Jun 18 07:00:05 Is there any C program on how to transmit date form the beaglebone?? many thanks Jun 18 07:00:14 sorry? Jun 18 07:00:32 <_Sy_> ty, we were looking at something like this for a device at work....we used MSF, but it wasn't anywhere neer accurate enough, we try to use GPS when available. Jun 18 07:00:40 av500: "extremely accurate" with an tcxo is kind of a joke :) Jun 18 07:01:00 Is there any C program on how to transmit date form the beaglebone with uart ??? Jun 18 07:01:20 sorry? Jun 18 07:01:31 you mean "data" Jun 18 07:01:33 not date Jun 18 07:01:34 date > /dev/ttyUSB0 Jun 18 07:01:35 right? Jun 18 07:01:38 Jason__: there is a whole book about it: "advanced programming in the unix environment", by stevens Jun 18 07:01:50 Jason__: get that, read it, be enlightened Jun 18 07:02:10 tltr Jun 18 07:02:22 I mean not echo date > /dev/ttyO1 Jun 18 07:03:03 I puzzled am Jun 18 07:03:17 I mean the C program,ecpecilly how to set uart baud,the date fomat Jun 18 07:03:29 ahhh - attack of the yoda speakers Jun 18 07:03:38 Jason__: try google Jun 18 07:03:44 Jason__: there are tons of example programs out there Jun 18 07:04:01 <_Sy_> There are several ways to do this in C, the easiest is to use fopen and open a stream directly to the port. Jun 18 07:04:26 _Sy_: he probably wants a raw tty, not a cooked one Jun 18 07:04:52 with mashed potatoes Jun 18 07:05:07 sorry,but I can't find few example in C on how to to configure read/write from/to a UART Jun 18 07:06:12 Jason__: google again Jun 18 07:06:15 <_Sy_> open google, type in "c serial port example" lots come up. Jun 18 07:06:40 Jason__: also read up on the difference between a "raw tty" and a "cooked tty" Jun 18 07:09:48 is there C serial port example with beaglbone Jun 18 07:10:22 shoud I have to find the register in am335x TRM Jun 18 07:11:12 <_Sy_> better crack on, cya l8r Jun 18 07:11:57 Jason__: you have linux running on the bbb, you dont want to access the hw directly Jun 18 07:14:09 @koth ,so how to Setting the baud rate and date format to transmit form /dev/ttyO Jun 18 07:14:20 use google Jun 18 07:19:17 recent chrome browsers do have an extension to access the serial. It won't take long before googles so'going to do it for you http://developer.chrome.com/apps/serial.html Jun 18 07:23:14 koen: is there something odd/wrong with the thumb2-fixes in meta-ti/recipes-kernel/linux/linux.inc? should the sed operate on .config instead of defconfig? Jun 18 07:33:14 Jason__: as said a couple of times, this is all easy to find on google Jun 18 07:33:37 if you cannot do that, I have doubts you can proceed even if we point you to exact souce code Jun 18 07:37:52 hi Jun 18 07:41:42 ciao Jun 18 07:45:41 ciao Jun 18 07:46:34 tasslehoff: dunno, I haven;t looked at meta-ti for a while now Jun 18 07:50:23 @av500, could u help me how to find the example ,type what in google?? Jun 18 07:58:50 [09:06:14] <_Sy_> open google, type in "c serial port example" lots come up. Jun 18 07:58:57 Jason__: it was given to you already Jun 18 08:01:19 or google for librs232 Jun 18 08:01:46 There's a librs232? And here I am using the device directly like a chump. Jun 18 08:02:18 so you've learned something new Jun 18 08:02:21 :) Jun 18 08:02:22 Ironically it's the one bit of my project that works 100% perfectly. Jun 18 08:02:49 ynezz: Haha yeah, mostly how to poke the baud rate/etc. in. Previously I'd mostly done it on Windows... Jun 18 08:03:21 And I guess a PIC, and some bit banging elsewhere. Jun 18 08:03:38 But they're kind of different to userspace level serial ports :P Jun 18 08:07:54 Electric_Monk: yep, you can use same API on linux/osx/windows https://github.com/ynezz/librs232/tree/next Jun 18 08:08:21 and there's even Lua binding for fast prototyping Jun 18 08:08:44 Cool, that'd have been nice Jun 18 08:11:11 The code I wrote was intended to run on the BeagleBoard on Linux, but developed on OSX, so all I was really missing was Windows anyway. Jun 18 08:11:17 And Windows serial ports are mildly easy :p Jun 18 08:12:48 easy nightmare, yes Jun 18 08:22:46 koen: ok. the same goes for linux.inc in meta-beagleboard :) Jun 18 08:25:26 good afternoon, everyone! Jun 18 08:25:54 a good JIHAD to you too Jun 18 08:26:40 koen: \o/ trundles off to test a non segfaulting 4.8/3.8 build Jun 18 08:28:22 ok so I put in my order for 3 BBBs, I will try to figure out the OMAP PM support later Jun 18 08:28:47 Vaizki: you are aware that the bbb does not contain an omap? Jun 18 08:34:10 yes :D sorry I am mixed up and with a fever here.. am working on an OMAP thing also. I am referring to this, https://groups.google.com/forum/?fromgroups#!topic/beagleboard/8UxM5pGMWLY Jun 18 08:34:26 more specifically suspending to memory Jun 18 08:34:58 which I assume will need me to instruct the PMIC to shut down all power rails except DDR3 refresh and RTC Jun 18 08:35:36 I don't really need the RTC for wakeup, I will have a MSP430 to kick the BBB back up Jun 18 08:36:15 TI all the way eh ;) Jun 18 08:38:51 well I guess I could save a lot of power just by sleeping the Sitara even if the PMIC still keeps all the rails powered Jun 18 09:15:35 It depends. Jun 18 09:16:01 In some cases, you can end up with >10% of maximum power, if you don't actually turn off the rails. Jun 18 09:16:37 RTC is probably under 5uA. Jun 18 09:17:03 Also, if you care a lot about reducing power, you can probably shut off 3/4 of the RAM. Jun 18 09:18:21 hmm really? BBB allows me to power off parts of the RAM refresh? Jun 18 09:22:03 dont think so Jun 18 09:22:45 if youreally mean partial ram refresh Jun 18 09:24:46 yea that's what I was assuming SpeedEvil meant Jun 18 09:25:04 Vaizki: No, the RAM allows you to configure parts - banks - of RAM off. Jun 18 09:25:35 To actually use this functionality may involve getting quite deep into things. Jun 18 09:25:54 - you turn off self refresh on parts of the RAM Jun 18 09:26:10 In practice, this will save under 1.5mA@5V or so Jun 18 09:27:07 wasn't that Russ' master thesis? Jun 18 09:28:59 ok hmm interesting. does anyone have power consumption figures for BBB without any tricks when running at a low voltage / clock speed and without any peripherals like usb drives and the HDMI off? Jun 18 09:29:32 * SpeedEvil would, but has no bbb. Jun 18 09:29:41 I couldn't find any by googling, just the figures from SRM which have all kinds of crap hanging on to it Jun 18 09:31:13 you can buy the answer for $45 :) Jun 18 09:31:19 I guess it's a matter of time until people start posting their battery powered BBB projects in blogs etc but I guess I'll just have to measure it on my own when I get them Jun 18 09:32:00 well I'd like to know a bit about what hoops are worth jumping through :) Jun 18 09:32:56 does anyone know how I could tie a port on my multi-card USB reader to a static /dev file? I have used udev for network card naming conventions before; but I'm unsure how I would identify a port on a card reader... Jun 18 09:33:03 The RSM just says Kernel Idling 350 mA but that's with HDMI monitor, USB HUB, thumb drive, etc etc Jun 18 09:33:12 Vaizki: In practice, 95% of people will take the 'normal' idle power consumption, and design/or not use/ the beagle in that state. Jun 18 09:33:49 so I assume that scaling down megahertz and turning off HDMI will cut that down significantl Jun 18 09:33:52 Few will look at ways to reduce power use with existing linux methods, and fewer still - (approaching zero) will look at ways to modify the kernel to reduce power Jun 18 09:34:17 Half is probably a sane guesstimate. Jun 18 09:34:20 why am I always in the approaching zero category Jun 18 09:35:35 I don't really want to modify the kernel. I want a working sleep mode on the BBB so I can use some normal tricks like turning off HDMI and scaling down voltage/MHz and using a specific governor to make sure my active power use is reasonable and then just completely SLEEP most of the time Jun 18 09:37:19 my other option is of course to just boot it up and shut it down Jun 18 09:37:40 finally back Jun 18 09:38:53 but since the PMIC seems to have nice power rail sequencing and sleep support matched with the SoC I don't think it's unreasonable to assume that a sleep-resume cycle on the BBB would become easily accessible to all via the standard kernels Jun 18 09:40:12 It's probably not - if stuff hasn't been omitted in hardware. Jun 18 09:40:28 no even the SRM makes a reference to it Jun 18 09:40:55 Vaizki, in theory there's updated m3 firmware for nicer power save Jun 18 09:41:13 in practice the new firmware leaves stuff like GPIO blocks unpowered Jun 18 09:41:15 For example - there may be support in the PMIC for 6 rails - which are all independantly switchable - and required for good power use - but only three inductors to enable those rails are present, and the others are connected together, to save $1.5 off the BOM Jun 18 09:41:15 in theory? :) Jun 18 09:41:30 so, hold on to your horses for when there's an updated kernel PM firmware :) Jun 18 09:41:50 do you mean leaves GPIO blocks unpowered even in ACTIVE state? Jun 18 09:42:01 but, the bone is not a power optimized design, it's a price optimized one :) Jun 18 09:42:18 Vaizki, it's complicated Jun 18 09:42:20 sure but sleep/resume is such a basic thing Jun 18 09:42:34 maybe on an arduino Jun 18 09:42:47 I'm not looking to shave mAmps off everything, just sleep and external wakeu Jun 18 09:43:09 again, that was not the design goal Jun 18 09:43:17 messing up sleep/resume is easy Jun 18 09:43:33 Vaizki, there's nothing that shouldn't be supported re: PM Jun 18 09:43:43 but in practice people are still working out the bugs Jun 18 09:43:50 patience please Jun 18 09:43:52 sure and that's fine Jun 18 09:43:55 * SpeedEvil sighs. Jun 18 09:43:58 I just couldn't find any info on it Jun 18 09:44:09 so I was wondering is anyone really working on it Jun 18 09:44:27 someone is over at TI Jun 18 09:44:32 Problem is 'patience please' occasionally turns into 'hmm - I wonder if they ever got that working - when you come across the device in 10 years in a drawer. Jun 18 09:44:41 6.1.13.2 in the SRM gives hope Jun 18 09:44:48 * SpeedEvil wishes this would just wor. Jun 18 09:44:56 (Which would be awesonme) Jun 18 09:45:17 SpeedEvil, well, it's all open source, you could report what's broken and let us know Jun 18 09:45:23 Currently, this feature is not included in the standard software release. The plan is to Jun 18 09:45:23 include it in future releases. Jun 18 09:45:25 jackmitchell1: you can identify the usb card reader by usb vendor id/device id Jun 18 09:45:26 which is RTC + DDR refresh and Jun 18 09:45:34 jackmitchell1: or any other way Jun 18 09:45:46 jackmitchell1: what is your exact question? Jun 18 09:46:20 panto, people are looking to do echo mem > /sys/power/state Jun 18 09:46:41 and then come back up in a semi-defined state after something wakes us up Jun 18 09:47:02 yes, I know Jun 18 09:47:04 do I want to dig into the kernel on how that happens? not really.. and if someone at TI is working on it I won't. Jun 18 09:47:16 but if they stop working on it then I might :D Jun 18 09:47:30 hey guys, on beaglebone black how do you update the kernel ? just drop the uImage initrd and everything in /boot/uboot ? Jun 18 09:48:02 The_DuDE, no Jun 18 09:48:11 depends on the distro Jun 18 09:48:16 angstrom doesn't use initrd Jun 18 09:48:57 yes, sorry but I am not going to be able to use systemd and other troll related stuff on my beagle Jun 18 09:48:59 you'll need the kernel uImage the boot dtb and the dtbos for the capes Jun 18 09:49:03 so debian 7 Jun 18 09:49:23 panto, most important for me is that if TI cares about making sleep/resume work then it reinforces my choice to go with BBB Jun 18 09:49:35 the kernel just works, how you package it is distro specific Jun 18 09:49:44 i only have for 2 days, also have a pi i need to replace with the beagle, removing angstrom was the 1st thing to do Jun 18 09:49:45 maybe someone else on the channel is debian aware Jun 18 09:50:25 well, put the kernel where the old kernel was Jun 18 09:50:27 as long as you realize that debian is not what the core developers use Jun 18 09:50:30 same for initrd Jun 18 09:50:39 anyway maybe I will finally start a blog and start posting my BBB experiences when I get them Jun 18 09:50:49 Vaizki, sure Jun 18 09:51:11 working with AVR and RasPi it's always been the case that someone else has already dug out the numbers etc and my oscilloscope can gather dust ;) Jun 18 09:51:30 KotH: I think I may have seen a way; my usb card reader has 4 ports Jun 18 09:51:50 KotH: one of them is uSD and I would like to symlink itto /dev/usd or something Jun 18 09:51:59 now, dmesg shows Jun 18 09:52:06 [ 7.866246] scsi 6:0:0:0: Direct-Access FCR-HS3 -0 1.00 PQ: 0 ANSI: 4 Jun 18 09:52:06 [ 7.884200] scsi 6:0:0:1: Direct-Access FCR-HS3 -1 1.00 PQ: 0 ANSI: 4 Jun 18 09:52:06 [ 7.905457] scsi 6:0:0:2: Direct-Access FCR-HS3 -2 1.00 PQ: 0 ANSI: 4 Jun 18 09:52:06 [ 7.929595] scsi 6:0:0:3: Direct-Access FCR-HS3 -3 1.00 PQ: 0 ANSI: 4 Jun 18 09:52:20 panto: the funny thing is that the kernel on the debian 7 image is the same one as the angstrom one, at least same version 3.8.13-bone21 Jun 18 09:52:34 where 6:0:0:3 is the uSD slot, so I may be able to use udev to identify on that id number Jun 18 09:52:55 panto, is anything on this page really relevant to the BBB as of today? http://processors.wiki.ti.com/index.php/AM335x_Power_Management_User_guide Jun 18 09:53:26 because that stuff is just downright awesome when it's all available Jun 18 09:53:28 if Jun 18 09:53:43 Vaizki, yes, most of that is relevant Jun 18 09:54:06 the only thing missing is the standby support Jun 18 09:54:14 all the cpu idle/cpu freq etc works Jun 18 09:54:18 ok excellent Jun 18 09:54:36 everything related to omap_mux is not Jun 18 09:54:47 yea for obvious reasons... Jun 18 09:54:48 sorry for not using the angstrom image, but I lost all my confidence in angstrom when I seen such full of bloatware image, systemd, gnome, cloud9 Jun 18 09:55:07 and no minimal image avalable Jun 18 09:55:10 don't they have a bare bones image? Jun 18 09:55:14 unless narcisus Jun 18 09:55:19 The_DuDE, err, you do know you can build an angstrom image with almost nothing in it (less than 20MB) Jun 18 09:55:23 hello Jun 18 09:55:27 i have a questiong Jun 18 09:55:30 question Jun 18 09:55:45 it is posible to have two usb host in beaglebone black? Jun 18 09:55:48 will you next ask if you can ask it? Jun 18 09:55:54 in fact angstrom is just so much smaller than debian/ubuntu for similar sw configs Jun 18 09:55:57 no, you need a usb hub Jun 18 09:56:08 Beaglehost, yes, and no Jun 18 09:56:15 you can use a usb hub Jun 18 09:56:24 but i revised the squematict and two usb is the same Jun 18 09:56:30 but 1 is for host Jun 18 09:56:36 Beaglehost: the am335x evm has two USB host ports; so it is supported by the processor; but the beagleblack doesn't have two ports brought out Jun 18 09:56:37 and the other no Jun 18 09:56:42 i have build narcisus images, had a old kernel, 3.2 stable or something Jun 18 09:56:51 or even older Jun 18 09:56:58 built* Jun 18 09:57:10 It so weird how you all type angstrom instead of Ã…ngström. Jun 18 09:57:24 The_DuDE, please take into account that the point of the default angstrom image is to have as much as possible preloaded in the emmc Jun 18 09:57:27 jackmitchell1 can build a kernel for activate the usb host? Jun 18 09:57:47 so, if you want a cutdown angstrom, just build your own image recipe Jun 18 09:57:56 or use narcissus Jun 18 09:57:57 Beaglehost: yes Jun 18 09:57:57 fun fact, you can even disable systemd Jun 18 09:58:06 panto: i undertand it is a demo, but a minimal sysvinit streamlined image should be also available Jun 18 09:58:18 The_DuDE: make one Jun 18 09:58:22 jackmitchell1. were is the kernetl for do it? Jun 18 09:58:25 its open source Jun 18 09:58:27 bitbake console-image Jun 18 09:58:28 patches welcome Jun 18 09:58:38 av500: that's the next step :d) Jun 18 09:58:40 i think that a lot of people need the second usb Jun 18 09:58:49 Beaglehost: I don't know, patches were posted to the linux kernel mailing list for enable dual usbs on the EVM a few days ago; you will have to go googling Jun 18 09:58:56 bether than have a usb withouse use Jun 18 09:59:09 Beaglehost, what do you want a second usb host that you can't do with a usb hub on the first one? Jun 18 09:59:11 ok Jun 18 09:59:11 but how would you break out the second usb? Jun 18 09:59:14 Beaglehost: I need no USB's, so can we have none? Jun 18 09:59:17 thank you kackmitchell1 Jun 18 09:59:34 one size doesn't fit all, so compromises have to be made Jun 18 09:59:56 panto but my system need the second usb port Jun 18 10:00:11 you haven't answered Jun 18 10:00:17 a need the band wight of the firts port Jun 18 10:00:25 i sature the band wight Jun 18 10:00:29 anothe usb port is not requiring a 2nd usb host Jun 18 10:00:36 do you need a second usb port or do you need a second usb host controller? Jun 18 10:01:03 and i can´t conect an usb hard drive and one 4G Jun 18 10:01:23 i need a second host controler Jun 18 10:01:24 what could you possible use to go over 480mbs, which is the usb2 speed! Jun 18 10:01:44 a hard drive can do well over 480mbs Jun 18 10:01:45 Beaglehost, I think you're confused Jun 18 10:01:53 haha coming from the RasPi dual-port but ultra-crappy USB this discussion is manic Jun 18 10:02:08 The_DuDe, I remember that the kernel have problem with dma Jun 18 10:02:11 it's a dual port USB (but it doesn't work) Jun 18 10:02:38 only think that the second port can be used Jun 18 10:02:45 for example Jun 18 10:02:48 the usb on raspi is crap indeed Jun 18 10:03:10 in my aplication i don´t use the usb link for configure the bealglebone black Jun 18 10:03:11 but it was built to teach kids python Jun 18 10:03:18 not to run media centers or routers Jun 18 10:03:39 Beaglehost, you are going to have trouble pushing two usb hosts at full speed on the black even with DMA Jun 18 10:03:43 at least the BBB seems to have a solid ethernet and a solid USB Jun 18 10:03:49 that's why I am migrating from pi to beagle Jun 18 10:03:51 the USB protocol's overhead is too much Jun 18 10:03:56 ethernet and usb Jun 18 10:04:01 yes Jun 18 10:04:07 ethernet on pi is over usb Jun 18 10:04:13 a need two usb full speed Jun 18 10:04:15 yea and it loses packets Jun 18 10:04:29 losing packets is not a big problem in tcp Jun 18 10:04:58 well, you can try making the bone's device port use OTG mode to switch it to host Jun 18 10:05:13 panto: somebody did that Jun 18 10:05:18 isn't there a cape adding a second usb host ? Jun 18 10:05:19 and posted pics where to solder Jun 18 10:05:20 ok panto Jun 18 10:05:22 but, the bone can't be everything for every person Jun 18 10:05:32 The_DuDE: how? Jun 18 10:05:35 over I2C? Jun 18 10:05:38 The_DuDE, I doubt it Jun 18 10:05:53 fsck, we need a compact PCI cape Jun 18 10:05:58 oh wait, that was my next question, what bus are capes using ? Jun 18 10:05:58 i think that normaly the second usb is not used Jun 18 10:06:03 then you plug what ever crap you want Jun 18 10:06:10 where is my thunderbolt 2.0 cape Jun 18 10:06:17 The_DuDE, the bone bus Jun 18 10:06:18 pci would be awesome Jun 18 10:06:23 panto how i can do it? Jun 18 10:06:28 i.e. just SoC pins Jun 18 10:06:56 Vaizki, just the cable for thunderbolt 2.0 would be more expensive than the bone Jun 18 10:07:10 I know :D Jun 18 10:07:29 pci implementation would be expensive too Jun 18 10:07:35 Beaglehost, https://groups.google.com/forum/?fromgroups#!topic/beagleboard/run8Q5TXFVY Jun 18 10:07:46 The_DuDE, we have our ways... Jun 18 10:07:55 there's more to beagle than just the ARM core Jun 18 10:08:08 panto: i know that, i am talking about power Jun 18 10:08:09 which reminds me I got to get cracking Jun 18 10:08:25 eggs? Jun 18 10:08:28 for tiropita? Jun 18 10:08:30 The_DuDE, what power? Jun 18 10:08:36 *the* power Jun 18 10:08:45 :D Jun 18 10:08:48 av500, you're just jealous I get to eat a tiropita every day Jun 18 10:08:54 no Jun 18 10:08:58 nice cheese filing Jun 18 10:08:59 I walk across the street Jun 18 10:09:03 crunchy fillo Jun 18 10:09:23 av500, I bet they don't use real feta in theirs Jun 18 10:09:25 so guys, any guides for updating the kernel ? Jun 18 10:09:30 and I can always tell my mom to make me some :) Jun 18 10:09:51 The_DuDE: with debian? Jun 18 10:09:58 I guess like in any debian Jun 18 10:10:00 The_DuDE, why don't you hit the debian channel? I have no clue how to package the kernel for debian Jun 18 10:10:04 av500: i am not stuck with debian Jun 18 10:10:14 there's nothing special about the bone and debian Jun 18 10:10:24 i will use anything streamlined and small Jun 18 10:10:54 The_DuDE, angstrom would fit the bill Jun 18 10:10:54 but narcisus kernel build are quite older than what I would expect Jun 18 10:11:05 3.8 is old? Jun 18 10:11:22 how do you get 3.8 in narcissus ? Jun 18 10:11:25 * panto has friends that ship product with 2.6.30ish Jun 18 10:11:59 panto: 2.6.32 Jun 18 10:12:03 the "golden" age of kernesl Jun 18 10:12:11 no it wasn't Jun 18 10:12:13 the stable age Jun 18 10:12:21 stone age Jun 18 10:12:29 well stones are stable Jun 18 10:12:36 same think hapenned wi 2.2.16 i think Jun 18 10:12:50 but good luck getting one to work with your phone's bluetooth Jun 18 10:12:58 sorry, it seems that i cannot type shit today Jun 18 10:13:11 The_DuDE, it appears that narcissus is not updated for the bone Jun 18 10:13:19 ask koen about it Jun 18 10:13:21 panto: duh Jun 18 10:14:15 koen: any news on updating narcissus for beaglebone black ? Jun 18 10:14:18 done :D Jun 18 10:15:07 The_DuDE: I'm negotiating with a paying customer to work on narcissus, so I'm not going to update it till I have a solid yes or no Jun 18 10:15:32 #beagle, the authoritative channel for answers (tm) Jun 18 10:15:56 koen: ah cheers Jun 18 10:16:21 The_DuDE, just use angstrom with bitbake Jun 18 10:16:36 git clone angstrom.git Jun 18 10:16:37 ./setup Jun 18 10:16:42 bitbake console-image Jun 18 10:16:49 3 lines; #exactsteps; next! Jun 18 10:17:05 does anyone run arch on bbb? Jun 18 10:17:16 some people do Jun 18 10:17:17 aaaahh, jackmitchell1 cheers Jun 18 10:17:35 The_DuDE: that's psuedo code; but that's pretty much all there is too it Jun 18 10:17:42 anyone here that is.. just wondering how well rounded the BBB support is for hardware like GPIOs, timers etc Jun 18 10:17:58 Vaizki, that's got nothing to do with the distro Jun 18 10:18:01 it's all part of the kernel Jun 18 10:18:09 so it's all sysfs? Jun 18 10:18:10 the kernel does support all of that Jun 18 10:18:20 yeah Jun 18 10:18:31 ok so nothing really in userland? Jun 18 10:18:33 even the cape probing, configuration what ever is part of the kernel Jun 18 10:18:44 hmmm ok. that's nice. Jun 18 10:18:52 I'm a beagle newbie Jun 18 10:18:56 besides some kind of udev method to populate /dev/ no Jun 18 10:19:00 as you can tell from a 100 miles away Jun 18 10:19:11 Vaizki, that's OK Jun 18 10:20:21 I don't even have the boards yet but I like them already... Jun 18 10:22:36 so once i have a narcisus image, should I be writing that image with cnelson's emmc flasher script ? Jun 18 10:22:39 I assume there's a high performance C-library or just memory-based access to BBB registers available if really needed? Jun 18 10:23:24 Vaizki: not really, but it's trivial to write Jun 18 10:23:33 just opening/writing/closing files Jun 18 10:23:44 which is why no one has really done it Jun 18 10:24:26 yea I know how to wrap sysfs trees into an API of my own, but it's probably not the fastest way to access GPIO for example Jun 18 10:24:49 Vaizki: unless you do it in a kernel module, that's the way to go Jun 18 10:24:51 then again with Linux not sure how much bitbanging etc can even be done Jun 18 10:25:10 you never know who's going to steal your time Jun 18 10:25:13 you can mmap down to the registers but that's the wrong way (tm) Jun 18 10:25:32 yea of course sysfs is a clean i/f Jun 18 10:25:35 Vaizki: PRUs on the BBB are another option Jun 18 10:25:41 oh right Jun 18 10:25:45 forgot about them Jun 18 10:27:04 Vaizki, for high performance you should use IIO Jun 18 10:27:17 there's a ton of options Jun 18 10:30:26 ok I'll have to read up on IIO also at some point then Jun 18 10:31:02 I thought it was mostly for reading ADCs with the kernel stuffing my input into buffers Jun 18 10:31:30 so I can just read it at leisure when the scheduler is gracious enough to give me some execution time Jun 18 10:40:38 ok seems like IIO is more widely adopted than I thought.. STMicro has drivers for all their MEMS devices :O Jun 18 11:09:22 * av500 download DOS 6.2.2 Jun 18 11:09:26 +s Jun 18 11:09:43 you're so bleeding edge Jun 18 11:09:54 yes Jun 18 11:09:57 for academic use Jun 18 11:10:20 there is also 6.20 Jun 18 11:10:25 for more conservative use Jun 18 11:10:30 who needs himem.sys anyway? Jun 18 11:11:34 in other news my new tape motor arrived :) Jun 18 11:11:49 tape motor? Jun 18 11:11:52 reliving the 80s? Jun 18 11:12:01 keesj: yes Jun 18 11:12:04 they died? Jun 18 11:12:10 never Jun 18 11:12:18 do tell Jun 18 11:12:18 av500, +1 Jun 18 11:12:30 keesj: well, for my tape deck Jun 18 11:12:37 the old one was making a horrible noise Jun 18 11:12:41 lawl Jun 18 11:12:53 tapes, I remember those! Jun 18 11:13:00 high bias ftw Jun 18 11:13:25 CrO2 Jun 18 11:13:36 MA-XG Jun 18 11:13:52 with the metal frame Jun 18 11:16:45 hmm, and the monitor that worked intermittently now works again Jun 18 11:16:52 after take apart and put back together Jun 18 11:16:58 crt? Jun 18 11:17:01 I bet once its back home it will fail Jun 18 11:17:05 samsung tft Jun 18 11:17:26 those didn't exist in the 80s Jun 18 11:17:33 oh btw any recommendations for a cheap handheld oscilloscope? only needs to go to 20MHz and 2 channels Jun 18 11:17:34 true Jun 18 11:17:49 you need a sony trinitron tube Jun 18 11:17:56 I had one Jun 18 11:18:04 in a HP 20" Jun 18 11:18:11 I had two Jun 18 11:18:14 DEC-branded Jun 18 11:18:40 got it for free, just paid the repair Jun 18 11:18:41 5x coax inputs Jun 18 11:18:46 yup Jun 18 11:19:00 we don't need no steenkin' edid Jun 18 11:19:34 modelines all the way down Jun 18 11:20:18 hmm, win8 embedded Jun 18 11:20:24 wonder if that runs on BBB Jun 18 11:33:42 french politicians want to regulate crowdfunding Jun 18 11:33:45 maybe not a bad idea Jun 18 11:38:02 as long we get to keep Krautfunding here Jun 18 11:38:30 their main concern seems to be ensuring that people get what they pay for Jun 18 11:38:50 or at least that the money is spent trying to give them that Jun 18 11:38:56 and not on hookers and blow Jun 18 11:39:01 damn Jun 18 11:39:04 there goes not ideay Jun 18 11:39:07 -y Jun 18 11:39:52 you're reading french news a lot these days? Jun 18 11:39:57 in the original klingon? Jun 18 11:40:10 I read all kinds of news Jun 18 11:40:16 english, french, german, dutch Jun 18 11:40:39 they all have some bias or other Jun 18 11:41:00 [13:13:00] high bias ftw Jun 18 11:41:16 they all need noise reduction Jun 18 11:41:18 no comments on a pocket DSO? Jun 18 11:41:26 that too Jun 18 11:41:35 I know it's off topic but at least people are alive here ;) Jun 18 11:41:39 Vaizki: DSO203 Jun 18 11:41:47 seeed Jun 18 11:41:59 coworker has it Jun 18 11:42:10 yea that's the one I was looking at, it was slaughtered in EEVBlog review though :) Jun 18 11:42:12 never did a single trace with it, but he already recompiled the firmware Jun 18 11:42:36 :) Jun 18 11:43:00 it will end up in a drawer Jun 18 11:43:43 well I need something cheap and low sample rate that runs without ac power and I can use it on a boat Jun 18 11:43:45 all this cheap hardware comes at a cost Jun 18 11:44:02 get a bigger boat Jun 18 11:44:07 of course I could get a slightly used Fluke 123 for under 1k USD but... Jun 18 11:44:21 <1k is cheap Jun 18 11:45:20 yea but this is the first time in 10 years I've needed a portable scope and not sure I will have much use for it afterwards either Jun 18 11:45:31 sell it Jun 18 11:48:55 * av500 has a scope module for a Gameboy Jun 18 11:51:27 haha, looking at a 16 bit level shifter from TI Jun 18 11:51:36 the only "sample" is for the BGA package Jun 18 11:52:07 get your oven warmed up Jun 18 11:52:39 hmm DSO 203 etc seem to be pretty much 200kHz analog bandwidth.. Jun 18 11:56:04 av500: scope module for a gameboy? sweet Jun 18 11:56:59 gameboy, what a sexist name! Jun 18 11:57:50 Maybe thats partially why Nintendo dropped that name Jun 18 11:59:31 Imagine the games you would want to play on/with a gamegirl Jun 18 11:59:39 Marketing... could call it gametransvestitehooker for all I care, wouldn't change my purchasing decision. Jun 18 12:04:33 I'd like to get a handheld or at least USB scope but I don't have a whole lot of motivation since the scopes at work are free to use. Jun 18 12:07:37 we've got a saleae too which is generally more useful than a scope for most of the stuff I do anyway. I guess Jun 18 12:08:08 some day I should haul over the old tek 454 that's still at my mom's house Jun 18 12:08:55 yea I have the saleae LA and it's a nice tool Jun 18 12:09:34 there's something about digital scopes that doesn't quite feel right Jun 18 12:09:38 not the cheapest or best but Works For Me Jun 18 12:16:44 Anyone done any testing on the Micron eMMC parts (like on the BBB) to see how they behave in powerloss during write situation? I went through the datasheet and didn't see any mention of brownout detection or anything of that nature. Jun 18 12:23:18 Fun idea of something to try. Corrupt ext superblock see if u-boot and linux are able to use/boot from one of the backup copies. Jun 18 12:23:31 why? Jun 18 12:24:01 Why is it a fun idea, or why try it? Jun 18 12:24:05 normally you'd want to fsck a damaged filesystem asap Jun 18 12:24:43 well if you just lost power and corrupted the superblock, not much fsck before boot? Jun 18 12:24:50 right... Jun 18 12:31:41 mranostay, linkedin wants to know if you know anything about software development, how should I answer? Jun 18 12:31:52 heh Jun 18 12:31:56 endorse him for trolling Jun 18 12:32:10 Crofton|work, I did but apparently there's some kind of filter you can enable.. :( Jun 18 12:32:29 and he was interviewing with intel at the time, so maybe not a bad idea :) Jun 18 12:35:26 Great... linked in invite from another recruiting manager. Jun 18 12:37:34 georgem, tell them you're very interested and want to meet for coffee, then go, drink free coffee, lead them on, setup interview, and don't show Jun 18 12:37:42 tell company you never got notice from the recruiter Jun 18 12:37:46 backstabbing is fun Jun 18 12:38:04 bradfa: I kind of did that with intel. Got nice weekend in portland out of it though :) Jun 18 12:38:12 +1 Jun 18 12:52:25 hi there guys, i am trying to install gento at the XM, as told here https://www.slashorg.net/51-Getting-started.html Jun 18 12:53:03 right now i on the step "Booting for the first time". But here no boot from flash (it even not reading) Jun 18 12:53:54 maybe it shows boot on s-video, not hdmi? Jun 18 12:54:12 but no flash reads. whats i am doing wrong? Jun 18 12:54:14 beagle-xm doesn't have onboard flash Jun 18 12:54:46 yep, i am doing it with microsd Jun 18 12:54:56 is here a way, to install gentoo on xm? Jun 18 12:55:03 of course Jun 18 12:55:14 please provide me to manual ;) Jun 18 12:55:33 sorry, don't have a link handy Jun 18 12:55:56 no official supported manual for it? Jun 18 12:56:01 no idea Jun 18 12:56:04 once the kernel loads, it's just like any computer Jun 18 12:56:21 well, yea, but i didnt understand how it loads Jun 18 12:56:38 there's plenty of documentation on that Jun 18 12:56:42 it's not gentoo-specific Jun 18 12:56:45 it reads %%%% file from first partition, which is u-boot, then what? Jun 18 12:57:09 the rom reads MLO, which reads u-boot, which reads the kernel Jun 18 12:57:19 whereis kernel stored? Jun 18 12:57:28 my 2.6.39 boots fine in yocto 1.2, but is stuck at "Starting kernel" on yocto 1.4. any good ideas for debugging? Entry point and Load Address are the same. Jun 18 12:57:29 anywhere u-boot is able to read Jun 18 12:58:50 well, AFAIK, kernel is binary file, which i am usually put on /boot partition(on x86 arch). And grub execute it. Where is kernel stored here? Cause i didnt found any setting for it in u-boot Jun 18 13:11:33 sorry, i am here, ISP troubles Jun 18 13:11:49 what about where is kernel location setting on u-boot? Jun 18 13:16:20 the kernel is normally on the root partition - same as standard Linux practice Jun 18 13:17:23 martinm: well, yeah, but usually, when i am booting with grub, kernel stored as single file in /boot partition Jun 18 13:18:15 as for the gyrations that come before that, there's a good discussion of things I haven't seen discussed elsewhere here: https://groups.google.com/forum/#!topic/beagleboard/lEMH0rvm6Ys Jun 18 13:18:21 martinm: AFAI think, i could replace that file with any ARM-compatible linux kernel, for ex: gentoo, but whereis? Jun 18 13:18:46 forget the occasionally needed separate /boot Jun 18 13:19:42 you can't boot with an empty SD card... at least not if it has a FAT partition! Jun 18 13:20:26 anyone around? Jun 18 13:20:40 bbl Jun 18 13:21:43 Is there an addon or cape board that has two or three RS485 ports on it? Jun 18 13:21:49 I cannot seem to locate one. Jun 18 13:21:58 make one Jun 18 13:22:10 can't be hard Jun 18 13:23:36 need a seperate board for the rs485 transceivers Jun 18 13:23:45 martinm: well, as mru said, ROM executes MLO, MLO executes u-boot.img, and what executes u-boot.img? Jun 18 13:23:47 there is a cape with one rs485 I think Jun 18 13:24:19 Oh? I looked but could not find one. I will revisit..... thanks. Jun 18 13:24:30 martinm: its just chroot to other partition, or what? i didnt understand. reading group Jun 18 13:24:56 u-boot.img reads a list of commands from uEnv.txt or something Jun 18 13:25:05 those commands load the kernel Jun 18 13:25:07 u-boot can do almost anything Jun 18 13:25:22 it has a script interpreter Jun 18 13:25:27 at least if u-boot works as usual on BB as I don't have one Jun 18 13:27:06 http://www.eewiki.net/display/linuxonarm/BeagleBone+Black Jun 18 13:27:27 shows you what kind of commands the uEnv.txt contains to find, load and run kernel Jun 18 13:37:32 .. and it's actually readable vs some of the GRUB2 shit I've had to wade through Jun 18 13:42:23 Someone spots a swallow outside of the office window. Monty Python jokes ensue. Jun 18 13:42:40 european or african? Jun 18 13:43:06 why does your office have windows? are you in marketing?? Jun 18 13:44:10 A northern rough winged swallow apparently. Jun 18 13:46:19 Have a 10 by 12 foot window right by office/cube. Jun 18 13:47:15 Our last building had almost no windows Jun 18 13:48:48 my office is wall-to-ceiling window on 2 walls (corner) Jun 18 13:48:57 I can tell you it's pretty hot in the summer Jun 18 13:49:57 need to get the building turned so that my corner points north Jun 18 13:56:54 i need help running matchbox keyboard on my beagkebone running ubuntu Jun 18 13:59:56 Does anyone know if there's a version of dtc for the debian build for the BBB which supports the -@ parameter ? Jun 18 14:04:22 morn' Jun 18 14:04:30 troll Jun 18 14:05:31 Has anyone gotten lxde working with ubuntu 13.04? Jun 18 14:06:46 * ogra_ would guess the lubuntu maintainers have Jun 18 14:06:59 and their users likely too Jun 18 14:07:01 i swear to god that has been asked 100 times here Jun 18 14:07:17 Trying to get it working on LCD3, but so far no luck, just a huge login screen.. Jun 18 14:07:28 hi eliasbakken Jun 18 14:08:02 panto: hi! Jun 18 14:08:06 has anyone got $mainstream_application to work? Jun 18 14:08:17 mugbook? Jun 18 14:10:21 Sorry, what? Jun 18 14:10:48 * ogra_ would gusess the $mainstream_application maintainers have Jun 18 14:10:53 and their users likely too Jun 18 14:14:31 * panto has a nagging feeling that prussdrv is working by accident Jun 18 14:18:59 any cpu core temperature sensors on bbb ? Jun 18 14:21:04 no Jun 18 14:21:19 well, the TRM mentions something Jun 18 14:21:22 but there's no driver for it Jun 18 14:22:48 check bandgap_ctrl register in the TRM Jun 18 14:23:02 ah Jun 18 14:23:03 so there is Jun 18 14:23:11 bitbang it Jun 18 14:23:11 nothing that a little /dev/mem cannot fix Jun 18 14:23:17 but there's absolutely no info about it Jun 18 14:23:33 I would guess that if there's no info it might not work reliably Jun 18 14:23:45 or TI did not qualify it yet Jun 18 14:23:51 its TMX after all Jun 18 14:23:54 :) Jun 18 14:24:01 there, ordered new caps Jun 18 14:24:02 mru: oh baby bitbang me one more time :P Jun 18 14:24:03 tex-mex?

Jun 18 14:48:01 maan, the learning curve from raspberry pi to bbb is too damn high ! Jun 18 14:48:57 so it's an opportunity for people to work on Jun 18 14:50:49 The_DuDE: yes, because the pi is a real "computer" Jun 18 14:50:52 its easy Jun 18 14:51:46 what part of real computer the raspberry pi has that beaglebone black hasn't? Jun 18 14:52:15 raspbian Jun 18 14:52:29 what, the distro ?

Thanks Jun 18 14:58:24 bradfa: you are the expert on that no? Jun 18 14:59:53 koen, are you in here? Have you tried installing wxpython? Jun 18 15:00:20 BebeSinSed, use an external i2c clock module with a battery Jun 18 15:00:36 I don't know if the battery trick will work Jun 18 15:00:41 ask gerald about it Jun 18 15:00:48 or try and find out Jun 18 15:01:32 I have mounted an external module, but I do not achieve that it works Jun 18 15:03:13 I have searched for the web and do not find the way of making it work Jun 18 15:05:54 what module? Jun 18 15:06:45 BebeSinSed, there is a Ph0rum thread about this Jun 18 15:11:34 Hey guys, I'm having trouble getting hostapd running on my BBB.

Jun 18 15:38:53 panto, -ENOTENOUGHCOFFEEINTHEWORLD Jun 18 15:39:03 a Hammond Novachord Jun 18 15:39:18 * mranostay harlem shakes in Jun 18 15:43:22 ant_work: hmm, time for special 'passive component cartridges" :D Jun 18 15:43:52 kfoltman, thats what I would do too...except they are all mounted on Barrier Strips... Jun 18 15:44:00 which means hand soldering. Jun 18 15:44:51 "But all this came at a price. We are not 100% sure but back in 1939 when it was released, it cost around $1,900. That may not sound a lot today but back then, the average price for a house was around $600!!! That means that today, a Novachord would cost roughly £700,000! " Jun 18 15:46:19 Hey guys, sorry to interrupt, but can I ask a BBB question? Jun 18 15:47:19 a question about beaglebone black in a beaglebone IRC channel? Of course not! Why would you think of that? Jun 18 15:47:22 TI_Trey: Don't ask to ask, just ask. :) Jun 18 15:48:40 as often as we're on topic, it's an honest mistake ;) Jun 18 15:49:04 beagle* is bargain Jun 18 15:49:11 /offtopic-mode off Jun 18 15:49:17 ant_work: how dare you Jun 18 15:49:24 what Jun 18 15:49:36 http://26-26-54.hardwarebug.org/146 Jun 18 15:49:38 enelar: I missed that you were working with the XM, been buried in bone and black stuff lately. Jun 18 15:49:45 eliasbakken: it has been a few years since I tried to use wx, ask Crofton|work :) Jun 18 15:50:51 hmm chat was being flaky, can you see this? Jun 18 15:51:03 yes TI_Trey_ Jun 18 15:51:06 ok Jun 18 15:51:12 trying to get hostapd running on BB Jun 18 15:51:18 so i can have some fun with Tor Jun 18 15:51:27 excuse me can someone tell me what is the difference between beagle board and arduino board Jun 18 15:51:57 Sagar: The Arduino is better, get one Jun 18 15:52:24 why Jun 18 15:52:27 I've compiled hostapd from the realtek sources but its having trouble starting Jun 18 15:52:58 Sagar: arduino (which is not one board, but an entire class of boards) is a microcontroller, a dedicated chip with no operational system and very low requirements. Arduino Uno has 2 kB RAM and 8 kB storage. Jun 18 15:53:00 basically i'm trying to replicated the OnionPi project but for BBB Jun 18 15:53:40 when i start it up I get the error "ioctl[SIOCSIWMODE]: Invalid argument" Jun 18 15:53:47 Sagar: Beaglebone is an actual computer, with microprocessor, 512MB of RAM (262144 times greater than Arduino Uno's) and 1 GHz clock (Arduino Uno has 16 MHz) Jun 18 15:53:56 ant_work, http://www.discretesynthesizers.com/nova/mp3/nova2.mp3 Jun 18 15:54:05 thats just freaking amazing Jun 18 15:54:07 *Beaglebone black Jun 18 15:54:13 so beagle board is better right???? Jun 18 15:54:26 along with messages that it can't set the interface to mode(3) or to master mode, and then a message that the rtl871... driver init failed Jun 18 15:54:27 * mru avoids realtek at all cost Jun 18 15:54:31 Sagar: much better, but also much more complicated and power-consuming Jun 18 15:54:42 No, arduino is better if you can't use google Jun 18 15:55:07 aren't there atheros-based usb dongles? Jun 18 15:55:37 what are the areas of application for beagle board Jun 18 15:55:41 eliasbakken, I haven't done anything with wx either Jun 18 15:55:42 TI_Trey_: which realtek chip are you using ? is it supporting AP mode ? Jun 18 15:55:49 probably, i looked around and it sounded like the rtl8192cu dongles were the recommended choice Jun 18 15:56:02 btw, beaglebone is a smaller version of beagleboard, and beaglebone black is a smaller version of beagleboard-xM Jun 18 15:56:19 errr no Jun 18 15:56:25 not even remotely Jun 18 15:56:54 ahhh what would you recommend? Jun 18 15:57:11 TI_Trey_: get something with an atheros chip if you can find one Jun 18 15:57:15 what are the applications of beagle board Jun 18 15:57:32 TI_Trey_: or Intel Jun 18 15:57:41 mru, I thought beagleboard was a red version of beaglebone Jun 18 15:57:42 you won't find an intel wifi dongle Jun 18 15:57:50 btw http://wireless.kernel.org/en/users/Drivers/rtl819x Jun 18 15:58:02 TI_Trey_: ask in #linux-wireless Jun 18 15:58:05 good afternoon everyone! Jun 18 15:58:09 in my experience realtek stuff rarely works Jun 18 15:58:14 KotH: JIHAD Jun 18 15:58:16 KotH: no jiha? Jun 18 15:58:17 Russ: what did you do to andrew? Jun 18 15:58:21 *jihad even Jun 18 15:58:28 good afternoon Jun 18 15:58:28 jihad finished for today Jun 18 15:58:33 mru: I have 3 realteks in use without problem so far. Jun 18 15:58:45 mru: must be losing the will in his old age Jun 18 15:58:59 beside, it's nice and sunny. summer has finally arrived... and my last exam for this semester is over :) Jun 18 15:59:17 KotH: I did my last exam _ever_ 10 years ago Jun 18 15:59:55 mru, what atheros chipset would you recommend? or just any of them? Jun 18 15:59:55 KotH, time for Chocolate? Jun 18 15:59:55 mru: you should have seen the girls in the exam! :-D Jun 18 15:59:58 ever or over? Jun 18 16:00:04 TI_Trey_: any Jun 18 16:00:35 KotH: I can't think of a worse place to pick up girls Jun 18 16:00:44 ka6sox: nah.. too warm for chocolate in pure form... but i had a few chocolate ice creams on the way to the lake and on the way back Jun 18 16:00:48 and i should use the nl80211 driver for hostapd? Jun 18 16:00:51 ptl: both, actually Jun 18 16:01:03 mru: oh.. it's not so bad. at least you have an obvious topic to talk about :) Jun 18 16:01:11 TI_Trey_: with that driver it is a requirement Jun 18 16:01:21 KotH: but you're not allowed to talk Jun 18 16:01:32 TI_Trey_: nl80211 usually yes Jun 18 16:01:34 mru: there is always time before and after the exam Jun 18 16:01:37 driver=nl80211 != driver=rtl871xdrv Jun 18 16:01:54 gotcha! thanks guys/gals Jun 18 16:01:55 mru: and a lot of anxious girls Jun 18 16:02:06 KotH: how's that a good thing? Jun 18 16:02:11 im gonna run to lunch and then Frys! Jun 18 16:02:13 in fact if you follow the same raspi tutorial you should be able to make it work on bbb Jun 18 16:02:18 I'll let ya know how it goes Jun 18 16:02:24 KotH: good pick-up strategy. Grab the girls attention when they are most fragile Jun 18 16:02:32 KotH, I think I'll go to the beach today...34C today here. Jun 18 16:02:34 *no comment* Jun 18 16:02:41 what, the girls or the attention ? Jun 18 16:02:42 mranostay: got any of those creeper cards left? Jun 18 16:02:43 mru: and if you had listened to your psychology professor, you would know that being anxious can lead to being excited about the guy/girl infront of you :) Jun 18 16:02:53 mru: there are at home Jun 18 16:03:15 mru: and yes, they did a study about that specifically :) Jun 18 16:04:03 it's not nice to exploit people like that Jun 18 16:04:27 it's not exploiting, it's giving yourself a higher chance ;) Jun 18 16:04:35 beside, they know that... or should at least Jun 18 16:04:51 if they're nervous about the exam, chances are they don't Jun 18 16:04:56 the local uni let out last week...so its just locals now. Jun 18 16:04:59 *no comment* Jun 18 16:05:00 if they dont act on the knowledge they learned just a semester ago, it's not my fault Jun 18 16:05:02 AMD announces its first 64-bit, 8- and 16-core, ARM-based server SoCs Jun 18 16:05:05 angstrom distribution is so unstable. Is ubuntu for BBB doing better? Jun 18 16:05:10 there's nothing nice about the 'game of love', it's all exploitation Jun 18 16:05:25 * mranostay notes his channel is extra dark today Jun 18 16:05:25 ptl: then you are playing the wrong game Jun 18 16:05:28 ptl, why so cynical? Jun 18 16:05:38 * mru agrees with ptl Jun 18 16:05:40 Criztian: works fine in mine, but I still got to get cloud9+bonescript+starthere working Jun 18 16:05:48 one can never be too cynical Jun 18 16:05:53 mranostay: nope, extra shiny Jun 18 16:06:00 mranostay: it's >30°C overhere Jun 18 16:06:22 Criztian: i think angstrom is too bloated to be unstable, but that's me Jun 18 16:06:30 June Gloom went away...good Beach Day... Jun 18 16:07:11 ptl: once inside gnome try going top right, click on the time and date, then select the zones and click on edit. All of mine crash there just to name one of the problems I encountered Jun 18 16:07:27 Bloated? Jun 18 16:07:31 Criztian: that's gnome Jun 18 16:07:34 Criztian: it's beyond bloated Jun 18 16:07:46 ptl: Locations (not zones) Jun 18 16:07:51 ka6sox: that happens when software eats to much at mcdonalds Jun 18 16:08:09 Criztian: starting gnome? I could not log in graphically. I mean, I do, but afterwards it just shows the background. Jun 18 16:08:09 plus I spent hours just trying to get ntp working without any success Jun 18 16:08:18 KotH, ah, I was wondering Jun 18 16:08:59 however I do not care that much for a graphical environment Jun 18 16:09:18 ptl: you watch only ascii-porn? Jun 18 16:09:33 * mranostay hands mru a creeper card Jun 18 16:09:42 wasn't there an 4chan board, just for that? Jun 18 16:09:44 mru: that's what graphical framebuffer was invented for :P Jun 18 16:09:45 * mru redirects mranostay to http://www.textfiles.com/artscene/asciiart/ASCIIPR0N/ Jun 18 16:09:47 mru: I mean, on my smaller-form ARM devices ÇP Jun 18 16:09:48 :P Jun 18 16:10:22 anything better than gnome porn, I suppose Jun 18 16:10:31 ant_work, I think I will buy the album Jun 18 16:10:34 or troll porn Jun 18 16:10:35 ptl: if you do date do you get correct date and time? Jun 18 16:10:58 Criztian: if i do date, it's a nice girl ;) Jun 18 16:11:13 ka6sox: there are also sw plugins Jun 18 16:11:23 ok, everybody troll jonmasters Jun 18 16:11:24 KotH: lol and surely it's not on angstrom Jun 18 16:11:45 Criztian: yes, but I've setup ntpdate (/etc/default/ntpdate) to get the time from my internal network ntp server Jun 18 16:12:01 ant_work, I am working on a Time-Lapse where some of this would be good. Jun 18 16:12:03 mru: trolling british? too easy! Jun 18 16:12:13 ptl: I cannot even make it work here in my distro Jun 18 16:12:19 Criztian: well, if she's scandinavian :) Jun 18 16:12:29 KotH: ;-) Jun 18 16:12:31 ka6sox: yes, that thing is definetely out of its time Jun 18 16:12:33 Criztian: you cannot make ntpdate work? Jun 18 16:12:49 ant_work, its amazing instrument Jun 18 16:12:57 Criztian: what distro ? angstrom ? Jun 18 16:12:58 are you running it as root? Jun 18 16:13:05 if it had tweeters...it would have Rocked Jun 18 16:13:11 ptl: I tried many different solutions. I even edited the npt.conf and all the rest Jun 18 16:13:18 The_DuDE: yep Jun 18 16:13:26 ntpdate doesn't need a .conf Jun 18 16:13:35 ntpdate pool.ntp.org should work Jun 18 16:14:00 Criztian: best is to stop ntp service (it conflicts with ntpdate), then try ntpdate with a few time servers. Open the firewall for network time protocol if you're trying to reach an external time server. Jun 18 16:14:02 The_DuDE: that's the problem, not even that one does. It aborts Jun 18 16:14:02 ka6sox: it's an analog-orgy Jun 18 16:14:21 Criztian: if ntpdate succeeds with the given time servers, you configure them in ntp.conf and restart the service Jun 18 16:14:28 ant_work, eargasm Jun 18 16:14:46 The_DuDE: ntpdate: res_query.c:251: __libc_res_nquery: Assertion 'hp != hp2' failed. Aborted Jun 18 16:15:07 something is messed up badly there Jun 18 16:15:28 [13:11] [root@beaglebone ~]# ntpdate caixacu Jun 18 16:15:28 18 Jun 13:15:15 ntpdate[3202]: step time server 10.0.0.51 offset -2.530532 sec Jun 18 16:15:29 I'm using BBB-eMMC-flasher-2013.06.06.img.xz Jun 18 16:15:54 ptl: that's a huge diff Jun 18 16:16:00 I am using Ubuntu on a SDCard Jun 18 16:16:16 * ka6sox pushes download button Jun 18 16:16:24 ptl: yeah, I'm planning on using ubuntu Jun 18 16:16:28 The_DuDE: it is... Maybe I should be running ntp instead of ntpdate so that I would get regular updates Jun 18 16:16:58 I don't boot my beaglebone black too often Jun 18 16:17:28 * ka6sox wonders whats in his new A5A Jun 18 16:17:40 a A5C ! Jun 18 16:17:45 Does anyone have timer interrupts executing on the CPU? I have played around with signal.h and it is really slow as well as non-realtime. I haven't had much luck deciphering the TRM section on interrupts. Jun 18 16:17:49 ka6sox: lots of magic smoke ;) Jun 18 16:18:02 ptl: I started asking here on the chan because I wanted to know if the Ubuntu distro is better Jun 18 16:18:33 Criztian: i am running debian, too much trolling in the ubuntu community Jun 18 16:18:45 too much ubuntu, I'd say Jun 18 16:19:14 Criztian: well, Ã¥ngström is minimalist, Ubuntu is much more manageable, but I am having difficult in setting up the same 'friendly' environment of Ã¥ngström Jun 18 16:19:44 one man's friendly is another man's hostile Jun 18 16:19:46 once bbb is going to be integrated in bbb i will default to angstrom tho Jun 18 16:19:48 and then there's lennart Jun 18 16:20:03 angstrom WITHOUT systemd obviously Jun 18 16:20:28 mru: well, comparing to fedora, ubuntu seems relatively lennart-free Jun 18 16:20:44 kfoltman: they have their own brand of nih instead Jun 18 16:20:56 it is rotten with shuttleworth, just another troll Jun 18 16:20:56 you mean libnih and friends? :) Jun 18 16:21:37 mru: but, I like to apply NIH in practice, "everyone else is a troll" is a good default assumption Jun 18 16:21:45 oh yes Jun 18 16:21:51 goigng to bother koen daily till bbb is part of narcissus :D Jun 18 16:21:57 actually, _everyone_ is a troll Jun 18 16:22:15 The_DuDE: bbb will never be part of it, only regular bb Jun 18 16:22:16 yes, but for one's own sanity, it's better to think one isn't Jun 18 16:22:27 The_DuDE: since there's no difference in kernel/bootloader Jun 18 16:22:36 agree Jun 18 16:22:41 koen: but there's a difference in device tree, right? Jun 18 16:22:42 kfoltman: one can only keep that up for so long Jun 18 16:22:48 eventually the truth gets through Jun 18 16:22:53 mru: one doesn't live forever, though Jun 18 16:23:01 what? Jun 18 16:23:01 koen: just add a emmc flasher script Jun 18 16:23:05 I'm disappointed Jun 18 16:23:27 you may get enough self-delusion to survive a decent lifetime Jun 18 16:24:48 The_DuDE: are you flashing debian from an image file? Is it stable? Jun 18 16:29:16 anyone use the linux sdk for the BBB?: http://www.ti.com/tool/linuxezsdk-sitara Jun 18 16:30:36 that's not "the linux sdk" Jun 18 16:32:11 koen oh, um so what is it? is there an ti SDK that is ideal to use on the BBB? Jun 18 16:32:48 TI SDK are best taken outside and shot Jun 18 16:32:53 mranostay, where did you get those holey boards? Jun 18 16:32:55 so noone can suffer from them any longer Jun 18 16:32:56 I am really confused whether to go for raspberryPi or beagle board Jun 18 16:33:04 koen: that's true of anything called 'sdk' Jun 18 16:33:10 sajjan: What do you want to do with it? Jun 18 16:33:28 if you want to curse at it, go with the rpi Jun 18 16:33:33 I want desktop performance with GPIO controls Jun 18 16:33:49 need to build a home automation system Jun 18 16:34:38 beagle Jun 18 16:34:41 desktop performance? Jun 18 16:34:55 not eaxctcly(Almost) Jun 18 16:35:20 sajjan the bbblack is great too Jun 18 16:35:20 I have beagle board xm with me,only problem is 1.3 v GPIOs Jun 18 16:35:46 the bone has 3.3V io Jun 18 16:36:17 hmm still need to spent more ,already spent 124 pounds Jun 18 16:36:23 sajjan http://www.adafruit.com/products/395 there are plenty of level shifters out there Jun 18 16:37:10 hmm ok, I am not sure what was in TI's mind when they targets its for real time use Jun 18 16:37:17 atleast the GPIO voltage Jun 18 16:37:25 huh? Jun 18 16:37:52 the beaglebone has 3.3V I/O Jun 18 16:38:03 so what are you complaining about? Jun 18 16:38:12 also, how is 1.8V contrary to realtime? Jun 18 16:38:13 GPIO voltage, Jun 18 16:38:19 voltage isn't critical for anything realtime Jun 18 16:39:06 oh sorry me basically from computer science back ground ,my electronics is not much good Jun 18 16:39:25 you mean to say I have to use some transistors to switch high voltages? Jun 18 16:39:35 what voltage do you need to interface with? Jun 18 16:39:42 5V atleast Jun 18 16:39:50 then you need some level shifters Jun 18 16:39:56 hmm ok Jun 18 16:40:01 there are ready-made ICs for that Jun 18 16:40:10 http://www.adafruit.com/products/395 Jun 18 16:40:35 which linux distribution is better in beagle (I have tried ubuntu,Arch,suse) , i need something light weight Jun 18 16:41:15 buildroot Jun 18 16:41:28 lightweight==Ã…ngström Jun 18 16:41:42 ptl: that's not lightweight enough for some ppl Jun 18 16:41:56 * mru would not consider it light at all Jun 18 16:42:36 ah ok , how much is angstrom support for a realtek wireless dongle Jun 18 16:42:39 it is all a question of which image you build Jun 18 16:42:49 there are small images available Jun 18 16:42:58 ok not distro wars again Jun 18 16:43:25 yes yes its highly sensitive Jun 18 16:43:44 driver support is kernel related, not distro related Jun 18 16:43:44 and too on-topic Jun 18 16:43:58 we aren't going to give you guys another warning :P Jun 18 16:44:30 people misuse the word distro a lot Jun 18 16:44:38 angstrom != distro Jun 18 16:44:45 angstrom == tool for making one Jun 18 16:44:47 people misuse words a lot Jun 18 16:45:00 not really Jun 18 16:45:00 panto: also angstrom != angst rom Jun 18 16:45:02 yes, i just need beagle to switch on one light in london(At my place) from my friend's place(Which is in India) Jun 18 16:45:06 openembedded is the tool Jun 18 16:45:14 angstrom is some settings the tool uses :) Jun 18 16:45:33 just more realtime over internet Jun 18 16:45:33 and the Yocto Project is an umbrella project to make embedded development easier Jun 18 16:45:39 sajjan: there are phone-operated switches you can buy... Jun 18 16:45:51 mru, but where is the fun in that Jun 18 16:45:59 yes Crofton Jun 18 16:46:02 he didn't mention needing fun Jun 18 16:46:14 why do we need Yocto *and* linaro? Jun 18 16:46:25 ptl: you don't know what linaro is, do you? Jun 18 16:46:32 I can buy products,what is the fun in that as an embedded guy Jun 18 16:46:37 maybe not. What am I missing here? Jun 18 16:46:57 yocto is a build system, linaro is a company Jun 18 16:47:59 yocto is not a build system Jun 18 16:48:05 * panto feels like an Airplane quote is coming up Jun 18 16:48:07 moreso than linaro is one Jun 18 16:48:11 it's an umbrella project, like freedesktop.org Jun 18 16:48:13 "Linaro is a not-for-profit engineering organization", and "The Yocto Project is an open source collaboration project that provides templates, tools and methods..." Jun 18 16:48:17 from their websites Jun 18 16:48:40 still looks like there is a lot of overlapping there because linaro also has its own tools and builds Jun 18 16:49:01 linaro engineers work mainly on the kernel and toolchain Jun 18 16:49:34 I also supports mtu, yes they are more into tool chain porting..and linux kernel (Ofcourse they have their own rootfs) Jun 18 16:50:03 mru, yocto is not a build system Jun 18 16:50:09 I give up Jun 18 16:50:55 _everybody_ uses yocto as the name for a special brand of open embedded Jun 18 16:51:13 so, yocto is just a buzzword? Jun 18 16:51:17 must be Jun 18 16:51:26 since nobody is able to explain what it *is* Jun 18 16:51:29 only what it is not Jun 18 16:51:40 it is not linaro! Jun 18 16:52:59 one group within linaro does produce a version of ubuntu with all the latest linaro components Jun 18 16:53:15 for a handful of boards Jun 18 16:53:16 that's mostly for testing, and is _not_ the primary purpose of linaro Jun 18 16:53:50 its a "framework" Jun 18 16:53:59 ka6sox: yocto? Jun 18 16:54:18 ys Jun 18 16:54:20 ya Jun 18 16:54:33 thank you for making everything crystal-clear Jun 18 17:00:55 we need to make a wiki page on this Jun 18 17:02:32 mru: https://plus.google.com/u/0/photos/100242854243155306943/albums/posts/5847178401075363570?pid=5847178401075363570&oid=100242854243155306943 Jun 18 17:03:19 now it's cocain clear Jun 18 17:04:01 ugly typeface Jun 18 17:07:00 that URL is longer then the content... Jun 18 17:07:18 that's web 3.0 Jun 18 17:07:26 blech Jun 18 17:07:45 web3.0 - where the URL contains the NSA tracking cookie? Jun 18 17:08:34 ynezz: now think how much data has been send, just for those few bytes you actually wanted Jun 18 17:08:41 just a cookie? it's so long that it contains whole receipt Jun 18 17:09:51 * KotH finds it interesting how everyone is calling the AKP a converative party, when they called them progressive just 5 years ago Jun 18 17:10:09 maybe they stopped progressing Jun 18 17:10:38 yes, 20 years ago, when their precursor party got formed Jun 18 17:11:12 KotH: opportunistic populism? Jun 18 17:11:28 sadly, erbakan who went to jail for forming a party that violated the separation of state and religion was a much better permier minister than anyone who came afer Jun 18 17:11:31 after* Jun 18 17:11:44 dm8tbr: nah.. uninformed media, making up "news" Jun 18 17:11:59 that's why I only read the onion Jun 18 17:12:08 there I _know_ it's all made up Jun 18 17:12:28 *g* Jun 18 17:12:44 mru: you can read "normal" media as well... it's all made up anyways Jun 18 17:12:58 probably, but the onion is funnier Jun 18 17:12:59 define normal Jun 18 17:17:02 mru: when i was in highschool, there was a greek girl in my class. when there was any noteworthy news, we compared what the different countries reported Jun 18 17:17:21 mru: it usually was the stories of 3 different events for .ch, .gr vs .tr Jun 18 17:20:44 sounds about right Jun 18 17:27:29 good morning Jun 18 17:27:43 jkridner: we have some questions re the sw for the workshop this weekennd Jun 18 17:28:07 hi cwicks Jun 18 17:28:32 * jkridner is just finishing up http://beagleboard.org/support/BoneScript/wired_basic_test/ to work with the latest image. Jun 18 17:29:07 I threw out my back yesterday and work has been a bit difficult. :( Jun 18 17:29:34 are Mark and Steve here? Jun 18 17:30:36 koen: just added you in G+, very nice office you have... I have some too, but it's more vertical, with shelfes and such Jun 18 17:30:46 cwicks: you still there? Jun 18 17:31:15 i will ask Mark to join the irc - sorry i'm multi-tasking a meeting Jun 18 17:46:35 jkridner, any bonescript activity here? Jun 18 17:46:55 I'm in the process of updating the bonescript library right now. Jun 18 17:47:03 sorry for delays. Jun 18 17:48:12 I have about an hour before FedEx picks up. Shall we plan on doing the updating in Atlanta? Jun 18 17:49:04 ah, hi may Jun 18 17:49:07 doh Jun 18 17:49:18 It shouldn't take long to do the update... Jun 18 17:49:22 I suppose so. Jun 18 17:49:39 I'll have it on a couple of USB flash drives to save time. Jun 18 17:50:03 I have 25 boards to update. Jun 18 17:50:12 I can do it Saturday Jun 18 17:50:33 k, are they all using the 05.08 image? Jun 18 17:51:23 I think so. I've only checked 1. I'm assuming they are all the same since they arrived at the same time. Jun 18 17:51:45 * jkridner is only planning to need to do 'mount /dev/sda1 /mnt; opkg install /mnt/xxx.ipk' Jun 18 17:52:03 hmmm... that isn't 100% Jun 18 17:52:23 I will create a check and bring a few flasher SD cards. Jun 18 17:53:29 So you just boot with the SD card in the the Bone updates itself? Jun 18 17:54:18 http://beagleboard.org/support/BoneScript/wired_basic_test/ now prints the dogtag Jun 18 17:54:40 not if we don't have to. Jun 18 17:54:55 Guess you didn't load anything extra on the boards? Jun 18 17:55:15 * jkridner thought you were adding VNC. Jun 18 17:55:20 or some other fun stuff like that. Jun 18 17:55:32 ptl: unicamp? Jun 18 17:58:44 No, nothing extra. Trying to keep it simple. Jun 18 17:59:59 I tried that wired_basic_test and get "***FAIL*** setDate returned {"data":"stdout: null","seq":1}" Jun 18 18:00:10 <_av500_> hmm, so Yocto is the Umbrella Corporation?

Jun 18 18:06:04 observe the photo included in the article Jun 18 18:07:45 may: That means you are running an old index.js Jun 18 18:08:06 * jkridner should probably reorder the tests Jun 18 18:13:07 may: error message should be more useful now Jun 18 18:14:54 may: you still there? Jun 18 18:15:16 Yup, I'm packing up the box.

Jun 18 18:27:23 agh Jun 18 18:27:28 Hey guys, I got an atheros based dongle and things are working much better now! Thanks!!! Jun 18 18:27:35 Hi, I need to derive more current from beaglebone? Is there any extension board for this purpose? Jun 18 18:27:58 just got a link to tell sngpt08 and he was gone Jun 18 18:28:47 more current? I don't think you can force more current to go through beaglebone's circuits. Maybe you want to control more current with a relay? Jun 18 18:29:53 jkridner: I'm about to seal up the box. I'm keeping one virgin bone so we test things on it. Jun 18 18:30:04 may: k Jun 18 18:30:11 Crofton|work: nice troll pic Jun 18 18:30:13 koen: what about Unicamp? It is the name of my college, means "UNIversidade de CAMPinas", or state university of Campinas (a Brazilian city) Jun 18 18:30:25 koen: but I work on IBM Jun 18 18:34:32 virgin bone... so wrong Jun 18 18:35:18 virgin bone... not virgin boner Jun 18 18:37:44 is bone a registered trademark? Jun 18 18:45:00 I dunno Jun 18 18:45:23 link to dongle TI_Trey ? Jun 18 18:46:06 I was able to find a netgear wna1100 at fry's Jun 18 18:46:24 great and that works as an access point? Jun 18 18:46:54 yes i was able to authenticate using my phone with the AP setup using WPA Jun 18 18:47:00 nice thanks Jun 18 18:51:18 Works Progress Administration. Jun 18 18:59:20 Hi, Is gertboard extension I/O board compatible with beaglebone? I need to derive high current from an extestion board controlled by beaglebone. Jun 18 18:59:57 any suggestions? Jun 18 19:00:47 "derive high current" is such a meaning-free phrase. what exactly do you want to do? Jun 18 19:01:04 control a motor Jun 18 19:01:37 ah, progress! simple on/off control? Jun 18 19:02:11 no, speed control of servo and also stepper motor Jun 18 19:04:02 okay, you need the power supply(s) and high current controls just as you would with any other computer. the only bone-specific parts will be the details of the glue between the controllers and the computer. might not be much... Jun 18 19:07:51 texan: this might address one part of that http://circuitco.com/support/index.php?title=BeagleBone_MSTP Jun 18 19:08:27 ...and this could be relevant to the other type? http://circuitco.com/support/index.php?title=BeagleBone_Motor_w/_Screw_Blocks Jun 18 19:18:44 hi joelagnel Jun 18 19:21:47 mranostay, hi matt Jun 18 19:21:51 what's up Jun 18 19:22:00 Intel treating you alright? Jun 18 19:27:26 Thanks Jun 18 19:29:51 * bradfa loves windows programmers Jun 18 19:43:30 * mranostay loves fuzzy people Jun 18 19:45:37 mranostay, I have picture for you! Jun 18 19:45:44 * bradfa goes to find fuzzy picture Jun 18 19:47:03 what is better, spi or i2c? Jun 18 19:48:40 A meaningless question. Jun 18 19:48:48 Which is better, French or English. Jun 18 19:48:55 (It's english btw) Jun 18 19:49:51 They are alternative ways of doing things, in general SPI is more flexible, but i2c may be quite adequate for some things, and SPI overkill that needs too many wires. Jun 18 19:50:37 Finnish! Because nobody expects the spanish inquisition! Jun 18 19:51:00 SpeedEvil, Us English or Queen's? Jun 18 19:51:01 SpeedEvil: thanks :) these are the answers I was looking for. Jun 18 19:51:31 which is better, french or fortran? Jun 18 19:51:39 bradfa: Scots of course. Jun 18 19:52:12 Scots-Irish? Jun 18 19:59:02 mru, clearly FORTRAN Jun 18 19:59:11 punch cards ftw Jun 18 20:00:58 algol or albanian? Jun 18 20:01:06 african? Jun 18 20:01:13 * bradfa is now out of his trolling league Jun 18 20:01:29 any opinions on musl libc c library? Jun 18 20:02:02 bradfa: I have opinions on rich felker Jun 18 20:04:38 mru, I'm listening Jun 18 20:06:09 erlang Jun 18 20:07:07 for the parallella supercomputer Jun 18 20:31:15 bradfa: Windows users are just regular shmucks, many of whom have no choice. Windows programmers are evil incarnate! :-) Jun 18 20:31:55 if evil pays well go for it :) Jun 18 20:32:50 * martinm sings, obscurely... what does it avail a man to gain a fortune and lose his soul? Jun 18 20:32:57 3v1L 1nc? Jun 18 20:33:11 wasn't that an animated feature? Jun 18 20:37:19 mranostay, you've already sold out once, now you're advocating doing it again? :) Jun 18 20:47:39 bradfa: i didn't sell out dammit! Jun 18 20:49:17 feisty! Jun 18 20:50:53 * bradfa hates the IEC Jun 18 20:50:58 martinm: souls don't exist so win-win Jun 18 20:52:21 bradfa: *sniff* take it back :P Jun 18 20:56:01 errrr ok that was nice.. my UPS just said brrzzzEEEEP and shut down Jun 18 20:56:32 doesn't strike me as particularly useful Jun 18 20:56:41 indeed I would tend to agree Jun 18 20:56:42 would not buy again Jun 18 20:57:13 and this was with a good AC feed? Jun 18 20:57:26 just about every UPS I've had has failed within a couple of years. Jun 18 20:57:28 well seems to be good, lights don't flicker etc Jun 18 20:57:45 I don't have a scope on my power feed now :) Jun 18 20:58:12 besides, it's supposed to switch to battery and not shut down if the AC goes bad Jun 18 20:58:15 (it's an APC) Jun 18 20:58:33 vaizki__, I bet it's out of warranty, no? Jun 18 20:59:14 properly designed products promptly fail as soon as warranty expires Jun 18 20:59:21 like Apple's Jun 18 20:59:24 * bradfa runs Jun 18 20:59:47 heh. my in laws still have a iMac G4 Jun 18 20:59:51 if you're lucky they miscalibrated the timer and they fail a few weeks before Jun 18 21:05:46 heh Jun 18 21:06:47 Anyone try to use pyo on a beagleboard-xM running ubuntu? Jun 18 21:07:18 I've had some cheap junk UPSes that didn't last too long. Have had good luck even with a couple of APCs, Best, and an MGE Jun 18 21:07:41 not sure how many of those still exist as separate companies :-( Jun 18 21:08:40 we need a bot to filter out any "^Anyone try" Jun 18 21:09:24 So it doesn't get lost in the backlog? Jun 18 21:09:24 surely any half-decent IRC client can do that for you? Jun 18 21:09:52 I have an iMac G4 in the next room.. and yes the APC is like 8 years old already Jun 18 21:11:23 So I have a device based on a generic usb codec, plug the thing in, use a library I wrote around pyo for manipulating audio streams from it and I get around 1 second of functionality before it dies. Nothing in dmesg or anywhere else about what's going on. Jun 18 21:11:53 does it come back if you unplug it and plug it back in? Jun 18 21:11:59 All of my unit tests work fine and the device works fine if used with a linux pc, just not on the damn beagleboard. Jun 18 21:12:59 vaizki__: So, clarify "come back" for me please? Jun 18 21:13:12 as in work again for a second Jun 18 21:13:23 or do you need to reboot or something Jun 18 21:13:35 I don't have to unplug it, if I run the test code again it again works for a second or less then locks up. Jun 18 21:13:42 oh ok Jun 18 21:13:58 Playing audio with mpg123 with it works fine on the beagleboard, so its not alsa. Jun 18 21:14:26 pyo itself works fine, since running an interpreter and generating a signal source and outputting test-tones works fine. Jun 18 21:15:09 eh Jun 18 21:15:16 so pyo works but doesn't? :) Jun 18 21:15:54 The library creates an object basically bundling a bunch of pyo objects that are wired in a certain way. Our codec has 2 microphone inputs and one speaker output. It takes both microphone inputs, delays one of them by a few micro seconds, then inverts it and sums it with the first input, then outputs that to the speaker. Jun 18 21:16:08 So its not very complicated. Jun 18 21:16:17 vaizki__: Totally. ;) Jun 18 21:16:44 Everything works in unit tests, just not the device with the library we wrote for the device. Jun 18 21:16:59 you'd probably want to strip down that until you find where it breaks Jun 18 21:17:01 But the device works on its own on the platform, and the library works on its own. Jun 18 21:17:30 ok but whatever you do with pyo and your device on BB it fails? Jun 18 21:17:31 does the library work with another device of that class, or is it too specialized? Jun 18 21:17:40 Eh, true. Could comment out sections and re-wire it, since it could be an object in the library that's broke. Didn't think of that. Jun 18 21:18:41 martinm: its just a sound device as far as I'm concerned, and it works fine with the beagleboard's internal sound card and even with the device's output since I can generate a tone with it and output that tone. Jun 18 21:19:17 I'm thinking the delay fails because some kernel buffer size in the beagle or something weird like that Jun 18 21:19:33 It's a PCM2904 basically, with the neccessary amps and parasitics. Jun 18 21:19:35 just off the cuff Jun 18 21:20:14 Yeah, I can sometimes get it to make weird clicking noises when it freezes, which kinda indicates buffer problems from what folks have been telling me. Jun 18 21:20:35 or sample rate issues Jun 18 21:20:43 what sample rate are you using? Jun 18 21:21:01 Well, sample rate should be good at 48000 which is what the PCM2904 is rated at. Jun 18 21:21:15 and when you say freezes, does the process hang or does it just mute? Jun 18 21:21:15 Less than that and we start getting into weird issues with where the microphones are located. Jun 18 21:22:06 you are doing noise canceling? Jun 18 21:22:19 Something internal to pyo locks up. stdout stops outputting magnitude values that I'm measuring, and if I try to stop the server object nothing happens, and if I try to start it again it says "Server already started!" Jun 18 21:22:32 hmmh Jun 18 21:22:38 We're doing beam shaping, kinda noise-cancelling. Jun 18 21:22:44 ah ok Jun 18 21:23:21 We're phase-shifting such that we have a directional gain towards the "front" of the device. We basically made a usb-driven hearing aid. Jun 18 21:24:06 And was hoping to use pyo to implement the audio processing piece. Jun 18 21:25:43 it's not going to run well off a normal hearing aid battery though ;) Jun 18 21:26:05 hehe, it wouldn't run at all off of a normal hearing aid battery. Jun 18 21:26:23 We also have an eeg it drives. The beagleboard is just the brains of the device. Jun 18 21:27:21 anyway, strip the code down until you have the smallest example that bugs Jun 18 21:37:47 Sounds like a plan, thank you very much. Jun 18 22:17:06 Ok. Jun 18 22:17:11 I got it to boot. Jun 18 22:33:24 Kristina: great Jun 18 22:33:27 next project! Jun 18 22:46:39 mru: troll project? Jun 18 23:44:50 hello all Jun 18 23:45:34 any of you gentelmen using Beaglebone black? Jun 18 23:46:05 nope Jun 18 23:46:32 don't lie to the gentlebeing, Mr. Troll Jun 18 23:47:52 any of you having problem with "GateOne SSH client " on beaglebone black? Jun 18 23:48:21 wtf is GateOne? Jun 18 23:48:28 no, but I just use a real ssh client Jun 18 23:48:30 it isn't working for me. it used to and I don't know why it stopped. Jun 18 23:48:42 real ssh client is a better solution. Jun 18 23:48:47 putty if you are on Windows. Jun 18 23:49:07 yeah, putty sucks, but, well, it's Windows Jun 18 23:49:29 * martinm speaks with great thankfulness that the suckage is there Jun 18 23:50:58 I am using ubuntu 12.04 and even when i try to use sudo ssh root@192.168.7.1 i get connection refused Jun 18 23:51:24 imprimis, the black is 192.168.7.2 Jun 18 23:52:03 your side should be configured as 192.168.7.1/255.255.255.240 Jun 18 23:52:39 Yes , you are correct typing error, this is what i get sudo ssh root@192.168.7.2 ssh_exchange_identification: Connection closed by remote host Jun 18 23:53:28 how long does that take? Jun 18 23:53:45 just a few second Jun 18 23:54:54 well, you don't need the sudo unless Ubu has gotten really really weird since I left, but that shouldn't be a problem Jun 18 23:55:22 conversely, if you have the sudo you don't need the root@ Jun 18 23:57:32 check ifconfig, route...

Jun 19 00:27:12 you are correct Jun 19 00:28:26 what if you leave off the sudo? Maybe Ubuntu "protects" root from evil external servers and that's what's killing it. A straw, but I can't think of anything else right now Jun 19 00:31:04 it does not make any difference please have a look at this http://paste.ubuntu.com/5778806/ Jun 19 00:32:14 okay, turn it up to eleven\\\\\\\ three. use -vvv Jun 19 00:35:51 The same, please see this http://paste.ubuntu.com/5778823/ Jun 19 00:37:53 yeah, I was afraid of that. ssh problems are either obvious or obtuse.

I hear that works well with some types of relationships Jun 19 01:26:37 vince1000: http://192.168.7.2:3000 Jun 19 01:27:09 dlg, I think people are surprised as it works fine for them Jun 19 01:27:31 I'm not a huge angstrom fan but I do see the advantages (now, I didn't used to) of it over other options Jun 19 01:30:27 well, the file "dropbear_rsa_host_key" does not exist http://paste.ubuntu.com/5778930/ Jun 19 01:32:50 then maybe you just need to restart it, since you've already achieved its lack Jun 19 01:36:28 i get the same output using cloud9, trust me its there just delete it Jun 19 01:36:51 bradfa_: theres a bug where the nic isnt up on boot, so it doesnt get a lease Jun 19 01:37:37 dlg, do you have systemd setup to start (enabled) that network?

Jun 19 01:40:52 yes Jun 19 01:40:57 http://archlinuxarm.org/forum/viewtopic.php?f=28&t=4996 Jun 19 01:41:13 thats quite old though Jun 19 01:41:15 and a different distro Jun 19 01:41:24 im looking forward to openbsd on this Jun 19 01:41:24 dlg, that's the arch forum Jun 19 01:41:44 dlg, have you sent this or seen this issue mentioned on the beagle mailing list? Jun 19 01:42:02 dlg, enjoy bsd, support for am335x is thin Jun 19 01:42:17 freebsd has some support I've seen but it's far from where Linux is today Jun 19 01:42:25 yeah Jun 19 01:42:46 pretty confident i can make openbsd do what i want once the major devices are supported Jun 19 01:44:48 dlg, I wouldn't hold my breath on support for am335x any time soon Jun 19 01:45:00 heck, Linux doesn't even have good support in mainline yet Jun 19 01:45:19 http://marc.info/?l=openbsd-tech&m=136691045117463&w=2 Jun 19 01:45:26 a good chunk of that is in the tree now Jun 19 01:45:31 the nic needs to be supported Jun 19 01:45:36 and some bootloader work Jun 19 01:45:41 but its all downhill from there Jun 19 01:47:33 dlg, if you get it working or contribute code to making it work, all the power to you :) Jun 19 01:47:59 i suspect workign with gpios will suck relative to linux Jun 19 01:48:18 but at least itll be a comfortable userland Jun 19 01:49:45 dlg, I personally don't find that much difference between userspace in Linux or BSD Jun 19 01:50:00 many similar packags are available and POSIX takes care of most things Jun 19 01:54:37 bradfa_: so there is still xmas for a camera Jun 19 01:55:54 mranostay, yes!
