**** BEGIN LOGGING AT Fri Nov 15 02:59:59 2013 Nov 15 03:00:13 that's pretty bad, but why would anyone hook that much power up to the hub even? Nov 15 03:05:03 can someone help me please with this: http://i.imgur.com/D0zxPUX.png Nov 15 03:05:12 I keep getting 0 as the value of P8_16 Nov 15 03:06:01 I have a 2.2kohm pull-up resistor between ground and the emitter side of my photodiode Nov 15 03:06:28 anybody? Nov 15 03:07:41 doesn't PD0 prevent it from traveling that direction? Nov 15 03:14:10 thurgood: prevent what? Nov 15 03:14:17 should it be the other way around? Nov 15 03:14:25 frege, did you draw that diagram? Nov 15 03:14:45 gui_: yeah Nov 15 03:14:49 PD0 is in the wrong direction Nov 15 03:14:50 gui_: why? Nov 15 03:15:01 the cathod is the negative pole Nov 15 03:15:15 diodes are unidirectional Nov 15 03:15:20 ok on my board the shorter leg of my photodiode is connected to the 2.2kohm resistance Nov 15 03:15:44 the "arrow" always point to the lower voltage (gnd) Nov 15 03:15:45 its either users that don't know what they are doing .. i.e. using a 12v psu on a 5v hub… or they have really crappy hardware that they are using... Nov 15 03:16:13 gui_ except when trying to catch back emf :) Nov 15 03:16:20 gui_: no difference, I switched it around Nov 15 03:16:30 where is PD0? Nov 15 03:16:39 and you're still missing a pullup resistor Nov 15 03:16:47 or does the BBB have one? Nov 15 03:16:49 bnz... in frege's diagram Nov 15 03:17:04 oh sorry.. not related to me :) Nov 15 03:17:21 gui_: I thought that 2.2kohm is the pullup resistor Nov 15 03:17:25 PDO is a photo diode.. Nov 15 03:17:56 frege, the pullup must be connected to the input pin and 3.3V Nov 15 03:17:59 the 2.2k is connected to gnd… Nov 15 03:18:30 i think you are missing a pull up and a pull down in that circuit.. Nov 15 03:18:40 gui_: so I also need another 2.2kohm between pd0 and input pin? Nov 15 03:18:57 i think you need the 2.2k to go to 3.3v and 10k-100k going from P8_16 to gnd.. Nov 15 03:19:46 yes, i agree with bnz Nov 15 03:19:49 ok I'm getting confused here, when you say 3.3v you mean Gnd? Nov 15 03:19:52 when the photodiode see's no IR the pull down keeps the pin in a known state.. when the diode see's some IR light the 2.2k will set you GPIO pin to high.. Nov 15 03:20:05 frege.. no 3.3v = VCC Nov 15 03:20:19 pull up* bnz Nov 15 03:20:24 I see no VCC :( Nov 15 03:20:40 yeah vcc is missing from that circuit... Nov 15 03:20:44 where is VCC? Nov 15 03:20:44 ... exactly Nov 15 03:20:46 gnd is 0 volts Nov 15 03:20:57 vcc is you "high voltage" Nov 15 03:21:03 usually 3.3 or 5 volts Nov 15 03:21:04 look at pins 3&4 of P9 these are 3.3v Nov 15 03:21:05 you mean VDD? Nov 15 03:21:06 http://stuffwemade.net/post/beaglebone-pinout Nov 15 03:21:10 BBB handles 3.3V Nov 15 03:21:13 I'm looking at this there is no VCC Nov 15 03:21:25 there is VDD though Nov 15 03:21:26 yeah VDD or VCC almost the same thing. Nov 15 03:21:28 P9_3 and P9_4 Nov 15 03:21:31 ah okay Nov 15 03:21:35 gui_ correct.. Nov 15 03:21:41 so I'm gonna redraw this Nov 15 03:21:58 it has to look like a T Nov 15 03:22:29 3v3 - 2k2 - T - PD - gnd Nov 15 03:22:42 and from the T branch, 10k - input Nov 15 03:26:49 gui_: http://i.imgur.com/tqJgVCE.png bnz Nov 15 03:26:52 how's this now? Nov 15 03:27:16 why should P8_16 be connected to the Ground? Nov 15 03:27:42 frege http://flockdraw.com/3kta8x Nov 15 03:28:09 I've been looking for a place like this for two days Nov 15 03:28:24 oh it's just drawing Nov 15 03:28:48 gui_: this site is better http://www.twiddla.com/1385925 .. Nov 15 03:28:51 you've go ground and power directly connected in this one Nov 15 03:29:08 s Nov 15 03:29:44 gui_: oh that's so fucking awesome! I think I understand why it should be like that Nov 15 03:30:12 think of the diode as a switch Nov 15 03:30:23 gui_: the current will flow into the photodiode, hit the ground and tries to come back? Nov 15 03:30:29 when open, the input is driven high Nov 15 03:30:45 right Nov 15 03:30:48 when closed, there's a lower resistance path to ground Nov 15 03:30:54 the wire that you have between 8_16 and gnu should have a 10k resistor in it.. Nov 15 03:31:06 gui_: but it doesn't make sense 2kohm to be there? Nov 15 03:31:44 I thought the resistor on 8_16 has to be lighter than the other resistor Nov 15 03:31:56 yes it does, because when the switch is closed, you can't short-circuit 3.3V and gnd Nov 15 03:32:01 you need a resistor Nov 15 03:32:46 what does short-circuit mean? Nov 15 03:32:54 oops, my bad Nov 15 03:32:58 i got the labels wrong Nov 15 03:33:11 aaaah so my logic was correct? Nov 15 03:33:12 oh dang i broke.. it Nov 15 03:33:42 we are redirecting the current to p8_16 by putting a lighter resistor there? Nov 15 03:33:55 nice Nov 15 03:34:06 let me try it on my board :) Nov 15 03:38:48 try this http://flockdraw.com/cvumwa Nov 15 03:38:56 nice!!!!!!!!!!!!!!!!!!!!!!! Nov 15 03:38:57 i do like that website… its nice... Nov 15 03:38:58 worked Nov 15 03:38:59 holly shit Nov 15 03:39:23 yeah it's simple Nov 15 03:39:29 but now it's always 1 !! Nov 15 03:39:30 hahahahahaha Nov 15 03:39:45 i'd never expect a "holly shit" Nov 15 03:40:15 short circuit by the way means that the short path resistance wise goes from ground to power.. basically frying stuff Nov 15 03:40:18 get a bright light close to the photo diode Nov 15 03:40:54 gui_: then it's supposed to become 0? Nov 15 03:41:00 yes Nov 15 03:41:11 i mean, I'm not sure Nov 15 03:41:35 if it's always one, it is either always getting to much light or never getting enough Nov 15 03:41:56 to, try a bright light, or turn off your ambient light for awhile Nov 15 03:42:15 oh no! Nov 15 03:42:31 I pulled the pd0 out and it remained 1 Nov 15 03:42:37 there is something funky going on Nov 15 03:42:41 let me double check my wiring Nov 15 03:42:53 no thats expected….. Nov 15 03:43:11 the PD0 will only pull the line low when there is IR light... Nov 15 03:43:18 normally it will sit high... Nov 15 03:43:30 at least on the circuit i drew.. …. Nov 15 03:43:39 yours is different Nov 15 03:43:42 oh k Nov 15 03:43:51 the resistor is between ground and pd0! Nov 15 03:43:52 then yeah you might have a problem Nov 15 03:43:53 it should be 1 without PD Nov 15 03:44:08 ok let me try again Nov 15 03:44:48 I got a 10k lux light therapy device here Nov 15 03:44:57 it must have enough infrared to turn this on Nov 15 03:45:23 if you need a IR filter you can try exposed 35mm film… it works really well as a IR filter Nov 15 03:45:32 get your tv remote Nov 15 03:45:39 !!!!!!!!!!!!!!!!! Nov 15 03:45:39 shit Nov 15 03:45:42 it's working! Nov 15 03:45:47 holy shit!!! Nov 15 03:46:09 I forgot to switch the photodiode Nov 15 03:46:13 some cell phone cameras have ir sensors/emitters too Nov 15 03:46:13 why the surprise? it's science, bitches! Nov 15 03:46:23 hahahah Nov 15 03:46:37 this is so fucking awesome! Nov 15 03:46:45 it's all magic Nov 15 03:46:45 nerd detected Nov 15 03:46:50 hahahah Nov 15 03:47:09 agh it may be magic but its well documented magic... Nov 15 03:47:22 so now when there is IR, it stays 0, when I cover it then it becomes 1 Nov 15 03:47:34 how can I get signal from it now? Nov 15 03:47:41 thats good… Nov 15 03:47:53 well.. there's still no reasonable explanation for gravity, so yes, it could be well documented magic Nov 15 03:48:13 you write some code that says if (PD0 == 0) do something… like count the pulses or add them into a buffer so you can read a stream... Nov 15 03:48:51 i can't help you too much with the beagle code itself only a rough frame work... Nov 15 03:49:12 pulses/ Nov 15 03:49:18 what do you mean by pulses? Nov 15 03:49:20 oh I see Nov 15 03:49:34 frege, do you know Python? Nov 15 03:49:37 oh pulses as in a burst of on then off.. Nov 15 03:49:38 so I read from this photodiode 100 times in a sec Nov 15 03:49:43 yeah I'm really good in python Nov 15 03:49:53 gui_: it's my job; writing python Nov 15 03:49:53 so look for Adafruit BBIO Nov 15 03:50:00 gui_: I'm using that right now Nov 15 03:50:05 cool Nov 15 03:50:34 it all depends on the frequency of the data stream that is in the IR light… think baud rate... Nov 15 03:50:35 I think I got the idea how to read it on and off and make a stream Nov 15 03:51:02 yeah it just needs a func of time to become a real signal Nov 15 03:51:18 ok one more question Nov 15 03:51:27 how do I make this more sensitive? Nov 15 03:51:37 should I drop 2.2kohm to 1kohm? Nov 15 03:51:44 then it let the current flow in easier? Nov 15 03:51:53 man electronic is fun!!!!!!!!!!! Nov 15 03:52:54 electronic is shocking Nov 15 03:52:57 I'm gonna try 630ohm Nov 15 03:52:58 #badjokegui Nov 15 03:53:23 gui: wanna learn what a jacobs ladder is? :D Nov 15 03:53:41 i think i've heard of it Nov 15 03:53:46 is it bad joke? Nov 15 03:54:29 it's still dull Nov 15 03:54:46 I want to make it sensitive enough so it can capture 850nm Nov 15 03:55:03 frege Nov 15 03:55:05 this sensor is a really capable one; 400 to 1000nm Nov 15 03:55:09 yeah gui_ ? Nov 15 03:55:14 you should tune the ration of the resistors Nov 15 03:55:27 but remember not to keep the absolute values too low Nov 15 03:55:29 ratio? Nov 15 03:55:32 or you could fry your bone Nov 15 03:55:36 R1/R2 Nov 15 03:55:39 jacobs ladder is great.. think frankenstein movies.. Nov 15 03:55:40 10/2.2 Nov 15 03:55:46 ahhh shit gotcha Nov 15 03:55:59 maybe change the 10k to 100k Nov 15 03:56:06 ok Nov 15 03:56:12 that will mean less current is needed to change the state of the pin.. Nov 15 03:56:14 bnz: how about the other one? Nov 15 03:56:56 do you have a voltmeter? Nov 15 03:56:57 that one is sorta there for protection of the diode.. it limits the amount of current going thru the diode.. you need to look at the data sheet and see how much current it can handle.. Nov 15 03:57:02 gui_: I don't :( Nov 15 03:57:29 oh dear my kernel dev just killed his beagle bone black… :( and now i have to fix it... Nov 15 03:57:42 he changed the contents of the eeprom and now it don't boot… Nov 15 03:58:00 gonna have to hang a another beagle bone off that to re-write the eeprom… Nov 15 03:58:01 bnz, that sounds so familiar Nov 15 03:58:04 here, hold this ;) Nov 15 03:58:04 but so familiar... Nov 15 03:58:11 now it stays 0 all the time Nov 15 03:58:23 frege, too sensitive Nov 15 03:58:34 yeah maybe not 100k maybe 47k? Nov 15 03:58:35 frege: what kind of sensors are you playing with? Nov 15 03:58:46 ir Nov 15 03:59:04 what kind of IR sensor? Nov 15 03:59:09 phototransistor? Nov 15 04:00:19 photodiode Nov 15 04:03:12 nice Nov 15 04:03:17 now it's sensitive to my IR LED Nov 15 04:03:41 gonna go running on threadmile, guys I appreciate it SO MUCH tonight was amazing Nov 15 04:04:09 it was my first circuit, and the good part was that I actually got a feel of how things work in elect. Nov 15 04:04:14 thanks! Nov 15 04:04:22 you're welcome Nov 15 04:05:16 no problem happy to help... Nov 15 04:08:51 i gotta go.. need to concentrate on the rescue of this BBB Nov 15 04:08:54 later all.... Nov 15 04:44:47 is the an ultrasound imaging cape? Nov 15 04:45:59 heh... nice idea! ;) Nov 15 04:52:10 ultrasound..imaging? Nov 15 04:52:52 Korra: yea the cape comes with a free pair of x-ray glasses as well Nov 15 04:53:04 Korra: order now and you get some sea monkeys as well Nov 15 04:53:11 sounds like just the thing to take to the beach Nov 15 04:54:00 yes Korra Nov 15 04:54:49 I was looking at this and see a lot of unneeded parts http://www.ti.com/solution/ultrasound_system Nov 15 04:55:21 if there was just the DSP available that would be something to work with Nov 15 04:55:59 this http://www.ti.com/solution/ultrasound_system_portable Nov 15 04:56:08 neat Nov 15 04:56:11 what are you gonna go with it? Nov 15 04:56:56 body fat measurements, if safe look at baby Nov 15 04:57:17 it really depends on the data Nov 15 04:57:24 possible Nov 15 05:01:51 another thought if there is no cape is to integrate with this device http://intelametrix.com/FullSite/index.html Nov 15 05:05:13 amanuel: just don't sell it in the states gotta pay the medical device tax, hehe Nov 15 05:05:45 no plans to enter that nest of pain ;) Nov 15 05:06:26 or just don't market it as a medical device lolol Nov 15 05:06:43 Korra: nice ;) Nov 15 05:07:07 Korra: hard to do that now Nov 15 05:07:27 Korra: virtually anything that can be construed as for a medical use goes under the microscope for the tax Nov 15 05:10:27 oh america and their wonderful healthcare system Nov 15 05:15:00 anything know anything about PLCs here? Nov 15 05:15:07 anyone* even Nov 15 06:15:34 any directfb users on the bbb out there?! ;) Nov 15 09:26:13 angstrom-distribution.org is still down, right? Nov 15 09:29:04 downorisitjusteme.com Nov 15 09:29:24 http://downorisitjustme.com/ * Nov 15 09:29:59 vmayoral as florian yesterday told he needs a way to reactivate it Nov 15 09:30:13 it is no primariy for him Nov 15 09:30:34 i see , thank you Nov 15 09:50:04 HI All Nov 15 09:50:25 I've always installed ubuntu on beaglebone white this way : Nov 15 09:50:46 cd to decompressed .xz image i.e. : Nov 15 09:50:52 cd ubuntu-13.04-console-armhf-2013-09-26 Nov 15 09:50:58 then: Nov 15 09:51:13 sudo ./setup_sdcard.sh --mmc /dev/sdX --uboot bone Nov 15 09:52:18 from today, sdcard are created correctly but beagle hung at boot with three leds on Nov 15 09:53:24 I tried other machines to burn sd and 3 or 4 different ubuntu version , as well different sdcards and beaglebone Nov 15 09:53:47 what does your serial console tell you? Nov 15 09:54:11 Koth , no ckecked yet Nov 15 09:54:24 that's the first thing you should check ;) Nov 15 09:55:22 you're right , as well as install.sh do some http check on external websites , i wonder if something is changed..... Nov 15 09:56:17 * KotH doesnt like scripts that call home Nov 15 09:56:23 especially if they need to be run as root Nov 15 09:57:12 sorry... I mean setup_sdcard.sh checks something on iternet... Nov 15 09:57:32 I'll try to setup serial console now... Nov 15 10:07:52 * KotH still doesnt like scripts that call home Nov 15 10:11:03 Hello Nov 15 10:13:23 I have s short question. Currently I am using a raspberry and cubieboard 2. With both i have the problem that GPU rendering is not possible with chromium. Do you know if the BeagleBone Black supports GPU rendering with chromium under linux? Nov 15 10:14:08 some day, yes Nov 15 10:14:09 maybe Nov 15 10:14:14 tldr no Nov 15 10:14:15 if TI fixes that SGX driver Nov 15 10:14:28 and if it fits whatever chromium needs Nov 15 10:14:33 which I have no idea Nov 15 10:14:34 about Nov 15 10:14:45 dob_: why does it not work on rpi? Nov 15 10:14:53 is GLES not enough? Nov 15 10:15:16 Oh on the pi i am not sure. Only the performance was very poor. Nov 15 10:15:28 On the cubie i am sure that the performance was very bad Nov 15 10:15:32 the pi has a good GPU Nov 15 10:15:38 thats about the only good thing on it Nov 15 10:15:53 but x is not accelerated, right? Nov 15 10:16:01 ah X Nov 15 10:16:03 right Nov 15 10:16:15 no idea, chrome on android runs nicely on a GPU :) Nov 15 10:16:15 is that still a WIP or did they just give up? Nov 15 10:17:34 yeah android is not a problem at all, but unusuable in my case. Nov 15 10:18:40 give in to the dark side Nov 15 10:19:20 dob_: dont go to av500's dark side, he has only cookies. come to our dark side, we have chocolate! Nov 15 10:20:20 :-) Nov 15 10:20:37 * ogra_ thinks KotH doesnt read enough G+ ... av500 has even VLC chocolate Nov 15 10:21:27 ogra_: yes, they didnt invite me to berlin Nov 15 10:21:37 evil Nov 15 10:21:39 ogra_: but dont worry, i will get my own personal box of vlchocolate Nov 15 10:21:48 is $500+bom a reasonable cost for one-off pcb prototypes? Nov 15 10:21:53 and of libavchocolate Nov 15 10:22:06 Korra: for just the pcb or including assembly? Nov 15 10:22:07 lol Nov 15 10:22:12 assembly Nov 15 10:22:37 last time I had to do just pcb it was something like 20 bucks for 3 Nov 15 10:22:43 Korra: how many components? how big is the board? how many layers? minimum feature size on PCB? Nov 15 10:23:02 Korra: how many trough hole solder points? Nov 15 10:23:09 Korra: oh.. and how many boards? Nov 15 10:23:25 1 layer ~15 components, beagle cape sized, 1 board. I'm just looking for a rough estimate, no design yet Nov 15 10:23:51 500 sounds reasonable to me Nov 15 10:24:10 yes, sounds reasonable Nov 15 10:24:24 NRE is probably 400, the assembly itself 100 Nov 15 10:25:31 Korra: for a single board with only 15 components, i would solder it myself Nov 15 10:25:42 Korra: it's not worth the effort giving it to an assembly company Nov 15 10:26:18 Korra: the PCB itself will probably cost somewheere in the region of 20-40 Nov 15 10:26:41 unless its 15 fine pitch BGA parts Nov 15 10:26:50 yes Nov 15 10:27:05 but those wouldnt be on a single layer pcb ;) Nov 15 10:27:52 ok thanks Nov 15 10:27:53 av500: the nice thing about BGA is, that you can solder them yourself if you have a good eye and a hot air gun from leister Nov 15 10:28:02 sounds like a reasonable price Nov 15 10:29:31 and typically with the BOM, they have stock on hand and source what's missing or do you provide the components? Nov 15 10:29:53 R and C's are usually on stock (unless you need special R/C) Nov 15 10:30:07 0815 diodes and transistors are on stock too Nov 15 10:30:14 everythig else: assume they have to buy them Nov 15 10:30:27 that's fair Nov 15 10:30:33 most assembly companies have a list of on stock items available to their customers Nov 15 10:37:21 hi! is there a way to get rid of these compiler warnings: 'va_list' has changed in GCC 4.4 ? afaik they can be safely ignored Nov 15 10:37:37 Anguel: please read the gcc documentation Nov 15 10:38:01 KotH: thanks :) Nov 15 10:39:27 How can I change runlevel at boot in Angstrom distro ?? ( as well inittab is not present ) ?? Thanks Nov 15 10:39:59 Freddie_: the systemd documentation is your friend Nov 15 10:41:13 I didn't know it was using systemd....thanks Nov 15 12:05:29 hi Nov 15 12:19:44 http://olimex.wordpress.com/2013/11/14/a10-olinuxino-lime-eur-30-open-source-hardware-linux-sbc-first-prototypes/ Nov 15 12:24:47 that looks good Nov 15 12:25:35 apart from being an A10 ... yeah Nov 15 12:30:30 what's wrong with an a10? Nov 15 12:32:01 that you have to jump through hoops when building a kernel ... it uses allwinners own idea of devicetree Nov 15 12:32:26 it could be worse Nov 15 12:32:29 beyond that its just another ARM indeed Nov 15 12:32:33 it could use acpi Nov 15 12:33:12 and BadBIOS :) Nov 15 12:34:00 BadBIOS affects all arm devices too! Nov 15 12:34:16 at least as soon as you connect a microphone to it Nov 15 12:34:32 hmm ? Nov 15 12:34:47 how would it replicate itself even if the mic recieved something Nov 15 12:35:22 subliminal message Nov 15 12:36:17 while the principle might work on ARM too i dont see how it would overwrite the ROM Nov 15 12:53:15 Hi. Anyone here who can answer me some questions regarding 1-Wire with Beaglebone Black? Nov 15 12:57:28 I just started to connect DS18B20 temperature sensors to the BBB. I used a device tree overlay found on www, It works with one and more DS18B20 on a single pin. But I need to connect 25+ sensors, and the max slaves is limited to 10. Which possibilities I have to connect more than 10? Nov 15 12:59:25 does the hardware protocol support that many sensors? Nov 15 12:59:51 Use other pins also or put some small microcontroller between BBB pin and the temperature sensors? Nov 15 13:00:47 Yes, I want to use other pins. My favorites was to use one pin per Sensor. But how can i configure the BBB to use several pins for 1-Wire? Nov 15 13:01:07 PeterJW: with the DT file :) Nov 15 13:01:33 Yes, I think that should be the way, but no clue how to do it Nov 15 13:01:38 but i dont know what the 1wire uses as system, wether it toggles an gpio or uses an uart Nov 15 13:01:56 well, read the DT, understand what it does, read the TRM and the datasheet of the sensor :) Nov 15 13:02:17 It's just a gpio pin, that is toggled with a fixed timing Nov 15 13:02:39 well, then there is no problem Nov 15 13:02:50 uh.. wait.. gpio and fixed timing? Nov 15 13:02:57 done in userspace? Nov 15 13:03:08 how fast is that 1wire? Nov 15 13:03:19 not fast Nov 15 13:03:28 Hi all. Several Beagle support pages say "To learn more about Cloud9 IDE and to synchronize the software on your board with cloud-hosted services, see www.c9.io." except I can't find any info on this on the c9 site. Anybody knows how? Nov 15 13:03:57 anyway it's actually a kernel module Nov 15 13:05:31 it's w1-gpio module Nov 15 13:05:33 Yes, there is a kernel driver for 1-Wire. I donÄ'' Nov 15 13:06:04 But how can I configure the w1-gpio module to work on serveral pins? Nov 15 13:06:10 jensk: ask again when jkrinder is around Nov 15 13:06:17 jensk: he is the cloud9 guy, afaik Nov 15 13:06:23 thanks Nov 15 13:06:46 hmmmmmm my 1wire DTBO has disappeared from my BBB?? Nov 15 13:06:49 wth... Nov 15 13:07:25 jensk: he is on mordor time Nov 15 13:08:25 by that he means us central Nov 15 13:08:30 ok what the hell is going on here Nov 15 13:08:38 where is my DTBO Nov 15 13:08:41 Vaizki: gremlins Nov 15 13:08:56 vmayoral: ciao Nov 15 13:09:07 vmayoral: did you get wpa working? Nov 15 13:09:23 KotH: ciao :) Nov 15 13:10:24 argh they are in /usr/lib/firmware my DTBOs Nov 15 13:11:19 and why is my bone_capemgr now .6 and no longer .8?? Nov 15 13:11:27 gngngh Nov 15 13:12:13 KotH: i gave it a try but i didn't manage to connect. There's something that i'm missing so i'm trying to reach the wpa_supplicant guys to ask. Nov 15 13:12:34 ok Nov 15 13:12:40 KotH: i referred them to https://gist.github.com/vmayoral/7484098, hope it's me doing something wrong Nov 15 13:13:17 [40819.040683] of_resolve: Could not find symbol 'ocp' Nov 15 13:13:19 ayeegh :D Nov 15 13:13:25 everything is broken :D Nov 15 13:13:33 ok I'm going back to 3.8 for a while Nov 15 13:13:39 what do you try? Nov 15 13:13:57 my 1 wire is also broken Nov 15 13:14:09 kernel is refusing to load my DTBOs Nov 15 13:14:53 must be 3.12 kernel symbols change Nov 15 13:15:20 so I'm installing linux-am33x-legacy which provides a 3.8 kernel Nov 15 13:15:34 I don't have time to debug this until next week Nov 15 13:17:05 if you play around with DTB files from the internet, you might want to consider staying with 3.8 also PeterJW Nov 15 13:17:34 anyway.. are you using the BB-1W dtbo? Nov 15 13:17:34 But I have no clue on what to change in the DTB files. Any hints? Nov 15 13:17:41 yes Nov 15 13:17:44 pastebin it Nov 15 13:20:53 http://pastebin.com/XrkngUqX Nov 15 13:21:46 vmayoral: i never configured wpa_supplicant directly, so i dont know Nov 15 13:22:00 vmayoral: and i have not taht much knoweldge about wifi Nov 15 13:22:44 PeterJW: do you understand the line: 0x34 0x37 /* gpmc_ad13.gpio1_13, OMAP_PIN_INPUT_PULLUP | OMAP_MUX_MODE7 - w1-gpio */ Nov 15 13:22:48 what it does Nov 15 13:23:12 I think so. It sets the pin "0x34" to mode 0x37 Nov 15 13:23:20 3.12 kernels doesn't have compatible DTBOs with 3.8 ones Nov 15 13:23:23 you need to define additional pins to be reserved by the cape and set them to the right mode Nov 15 13:23:24 KotH: thank you! i'll try figuring it out :) Nov 15 13:23:32 do not taunt the 3.12 monkey Nov 15 13:23:46 I tried to add a line with another pin, but it doesn't worked. Nov 15 13:24:00 KotH: maybe i can also give it a try with wicd, have you used it on the BBB running Angstrom? Nov 15 13:24:01 also in the next fragment you need to modify gpios = <&gpio2 13 0>; Nov 15 13:24:14 ah, okay. Didn't do that Nov 15 13:24:22 not sure of the syntax off hand Nov 15 13:24:25 But which syntax? Nov 15 13:24:32 panto maybe remembers it :) Nov 15 13:24:47 panto is really in friday mode now Nov 15 13:25:18 ok well good for you.. and why did dtbo's break in going to 3.12? Nov 15 13:26:07 that's the perils of straying off the supported path Nov 15 13:26:14 http://www.cs.fsu.edu/~baker/devices/lxr/http/source/linux/Documentation/powerpc/dts-bindings/gpio/gpio.txt Nov 15 13:26:14 overlays are not mainline Nov 15 13:26:20 ah Nov 15 13:26:24 didn't know that... Nov 15 13:26:39 and other people are breaking dt in abandon Nov 15 13:28:02 PeterJW: let me try to mod mine... Nov 15 13:28:17 I just need to find out a good pin to use for second W1 Nov 15 13:29:45 Okay, I will try here in parallel Nov 15 13:30:10 I think you basically need to replicate the onewire@0 block as a second onewire@1 Nov 15 13:30:28 Okay, I will try. Nov 15 13:30:51 or you are really lazy you can of course just copy the whole .dts file and make each W1 pin into it's own "cape" Nov 15 13:30:59 ^--- if Nov 15 13:40:34 Didn't get it to compile Nov 15 13:43:45 I got it to compile but it gives errors Nov 15 13:44:08 I used pin gpio1[12] which is mux offset 0x30 it seems Nov 15 13:49:02 *ö Nov 15 13:49:15 *lol* Same as i use for trying :-) Nov 15 13:49:44 But I'm not able to make it compile, with onewire-section copied Nov 15 13:51:41 [ 429.224327] Unable to handle kernel NULL pointer dereference at virtual address 00000000 Nov 15 13:51:42 ooops Nov 15 13:51:49 :D Nov 15 13:53:40 ha. I think it worked. Nov 15 13:54:08 kernel oooppps? Nov 15 13:54:30 Just compiles or really workes? Nov 15 13:54:39 http://pastebin.com/cMXESZSk Nov 15 13:54:45 at least that compiles and loads Nov 15 13:55:25 the BBB is 250km away so I can't test if it really works :) Nov 15 13:55:41 vmayoral: i dont own a bbb Nov 15 13:56:16 Ah, okay. So I will try Nov 15 13:56:21 Give me a few minutes Nov 15 14:01:00 koth me neither still I know more than some owners Nov 15 14:01:14 probably more than 99% of owners Nov 15 14:01:33 just look at us copy & paste dtbo's together here ;) Nov 15 14:01:43 Vaizki, your my here hero. Nov 15 14:01:47 lol Nov 15 14:01:52 Compiles and works in real system. Nov 15 14:02:00 oooh nice Nov 15 14:02:04 \o/ Nov 15 14:02:04 That's really great, you made my day(s). Nov 15 14:02:18 you can send me champagne Nov 15 14:02:19 Looking since wednesday for a solution Nov 15 14:02:43 via e-mail? ;-) Nov 15 14:03:23 just send your credit card details and I'll handle the procurement locally Nov 15 14:03:33 lol Nov 15 14:04:03 but tbh I should probably try to learn how the DT stuff works.. like really works. Nov 15 14:04:55 if I do that, then they will dump the whole thing Nov 15 14:04:56 Yes, that's weird stuff. Saw it 3 days ago the first time Nov 15 14:06:47 hmmh I can't even find the stock DT definition for Arch on 3.8 Nov 15 14:06:49 it is not weird Nov 15 14:08:31 At the first view it is. A the second view it get's a little bit clearer Nov 15 14:10:44 okay, thanks for the quick help. See you soon Nov 15 14:57:46 hello, how can i write a non-flasher image to the eMMC on my BBB? Nov 15 15:12:37 ? Nov 15 15:25:39 KotH : I'm into serial console of beaglebone white won't boot anymore with usual installing method Nov 15 15:26:33 it says: uenvcmd was not defined in uEnv.txt Nov 15 15:26:57 trying eMMC (BeagleBone Black) Nov 15 15:27:07 but i'm using a old white one Nov 15 15:27:10 then: Nov 15 15:27:34 mmc_send_cmd : timeout: No status update Nov 15 15:27:55 Card did not respond to voltage select Nov 15 15:28:09 mmc1 (part0) is current device Nov 15 15:28:24 bbwhite is hung with three leds on Nov 15 15:30:17 Freddie_ what now you are using from bbb for bb white? Nov 15 15:30:24 +bootenv Nov 15 15:32:35 I was explaining before that the good old method for installing ubuntu in my beaglebone white : Nov 15 15:32:39 ./setup_sdcard.sh --mmc /dev/sdX --uboot bone Nov 15 15:33:24 works no more , tried many microSD , more beaglebonewhite, more linux pc for burning sd process Nov 15 15:34:42 maybee your bb white is broken Nov 15 15:35:02 probably setup_sdcard.sh script point to something new on http webpage that is changed for the black ones ? Nov 15 15:35:14 no , tried more bbwhite cards Nov 15 15:41:47 you can try as many cards as you want when your bb white is broken none will work Nov 15 15:43:57 I mean I own more beaglebone to check, all of them working ok i.e. with angstrom or already working ubuntu SD Nov 15 15:44:19 o.O Nov 15 15:44:26 I dont get your problem than Nov 15 15:45:00 I also own several microSD that works ok if I install Angstrom but when installing ubuntu the way described they wont start Nov 15 16:03:34 from what I understood , it seems the flashed SD want to starts my BBwhite like it was a BBBlack with its internal eMMC Nov 15 16:04:08 fix your uenv.txt Nov 15 16:04:24 but the procedure and distro used to burn the SD was the same used succesfully months ago.... Nov 15 16:08:55 and? Nov 15 16:08:59 anyway Nov 15 16:09:06 I am heading home Nov 15 16:09:10 till later maybee Nov 15 16:27:18 Anyone interested in adding sound capability to their beaglebones? Nov 15 16:36:34 as in? Nov 15 16:37:14 <|PiP|> Can someone explain what the uenv.txt file is? I'd like to be able to boot my beagleboard black off a USB key (since my SD card port is damaged unfortunately and I can't get it repaired) Nov 15 16:37:36 |PiP|: the topic has a link that helps a bit... Nov 15 16:37:42 http://ahsoftware.de/Beaglebone_Black_Boot_explained.svg Nov 15 16:38:07 uEnv.txt sets environment variables for u-boot, the bootloader used to load the kernel. Nov 15 16:38:45 do you want the kernel and everything on the USB key or just the root file system? Nov 15 16:38:56 both are options and are just a few uENV.txt entries away. Nov 15 16:39:10 <|PiP|> where is the uenv.txt file stored? Nov 15 16:39:23 it can be stored on the uSD or the eMMC (on-board flash) Nov 15 16:40:02 <|PiP|> if i change it and screw it up, is there a way to revert? Nov 15 16:40:16 <|PiP|> (my sd card slot is broken so i can't use the sd card unfortunately) Nov 15 16:40:28 it is a lot easier to debug setting environment variables for u-boot using the serial port, but it requires a special cable. as long as you put the right stuff in uenv.txt, you should boot off of USB fine. Nov 15 16:40:57 <|PiP|> oh okay. well i want to put an entire image on the USB key Nov 15 16:41:08 there isn't an easy way to revert if you don't have a uSD card to boot from... it is possible to boot over the USB client or serial, but they require running special code on your computer to perform the boot. Nov 15 16:41:28 <|PiP|> basically, this: http://www.beaglebone-asterisk.org/ Nov 15 16:41:50 <|PiP|> so i'm assuming the kernel and everything would boot off the USB too Nov 15 16:42:17 <|PiP|> and basically, i'd leave the bbb to always boot off a USB key if that's possible Nov 15 16:43:32 <|PiP|> what would i need to modify the uenv.txt file to? Nov 15 16:43:48 you can have SPL and uboot on emmc Nov 15 16:43:53 and load the rest from usb, yes Nov 15 16:44:13 * jkridner needs to think a bit about the args that need to be put on the uEnv.txt... Nov 15 16:44:32 you should be able to currently edit uenv.txt by plugging the board into your host and having it show up as a flash drive... Nov 15 16:44:57 if you screw up uenv.txt, you won't be able to do that anymore because linux won't be running to share the eMMC as a flash drive. Nov 15 16:45:21 so, it unfortunately has to be right the first try if you don't have a serial cable. :( Nov 15 16:46:36 |PiP|: guess the best thing is for someone to duplicate your setup that has a serial cable and create a uEnv.txt that would be known to work. Nov 15 16:46:52 * jkridner doesn't have time to do that right now Nov 15 16:46:58 * jkridner is meeting someone for lunch Nov 15 16:55:12 <|PiP|> i dont, but i do have another BBB that works with microsd Nov 15 16:55:46 <|PiP|> bought two, one was damaged unfortunately, wanted to use both as a voip pbx Nov 15 16:55:59 <|PiP|> thanks for your help Nov 15 17:02:04 |PiP|: use the one with the working uSD to test your uEnv.txt. You can load a uEnv.txt onto your uSD to test it and once it works, copy it over to the eMMC to test it, then copy it to the eMMC on the board with the broken uSD. Nov 15 17:27:48 Greetings. Nov 15 17:39:18 <|PiP|> i have no idea what to put in the uenv file Nov 15 17:42:04 what are you trying to do with it? Nov 15 17:47:55 <|PiP|> boot off the USB key Nov 15 17:48:10 <|PiP|> which has the image from this on it: http://www.beaglebone-asterisk.org/ Nov 15 17:49:27 <|PiP|> or alternatively, flash that image onto the BBB Nov 15 17:49:38 <|PiP|> without using the SD Nov 15 18:45:25 you can't boot off a usb key Nov 15 18:46:03 you can boot from uSD, eMMC or from an attached computer over USB. Nov 15 18:46:29 ok there's also network boot but I have a feeling you don't want to go there Nov 15 19:02:58 Hello I bought beaglebone black from my friend but even after installing driver for it, it not detected and flashing of boot LEDs also not happened .why ? Nov 15 19:03:37 how much power can your USB port source? Try running it from a powered hub. Nov 15 19:05:10 500 mA.And there is no any other component I connected to it.Even no USD card. Nov 15 19:06:09 500mA is not a lot Nov 15 19:07:00 Try powering it with an external 5v brick? Nov 15 19:07:33 Is it possible that there is no any Kernel inside eMMC ? Nov 15 19:08:01 It sounds like you're not getting power. Nov 15 19:08:24 Ok Thanks Nov 15 19:51:48 is there no way in Win7 to reformat a RPi/BBB imaged SD card? All I ever get is my same ~60MB fat32 partition. SDFormatter doesn't even clear it. I do this with gparted in Linux all the time but at work I'm using my Win7 machine primarily. Nov 15 19:57:43 <_vicash_> hi there. what is the package for Sound applications in the Angstrom for the BBB. Nov 15 19:58:16 <_vicash_> I am trying to have an app make a sound using command line by playing a stupid MP3 that makes a special bell sound. this is for a simple project that uses a BBB as a custom alarm Nov 15 19:58:33 <_vicash_> there is an application for making that sound but I cant remember the name. Please advise. Nov 15 20:01:09 _vicash_: there are a number of utilities available but mplayer might be the easiest for a mp3 from command line Nov 15 20:01:26 _vicash_: easier would be to have it as a wav file and just use aplay Nov 15 20:02:11 <_vicash_> prpplague: sure. wav file is fine too. thanks. Nov 15 20:02:35 <_vicash_> prpplague: what about sox ? Nov 15 20:03:02 _vicash_: probably good as well Nov 15 20:03:41 <_vicash_> prpplague: thanks. Nov 15 20:19:05 <_vicash_> \part Nov 15 21:36:32 Can I boot from SD card instead of the flash memory? Nov 15 21:36:51 Are there any libre drivers for the GPU? Nov 15 21:37:09 How do I use a USB adapte Nov 15 21:37:50 for wireless Nov 15 21:47:26 my aren't we patient Nov 15 21:50:04 Wow, over a minute. Nov 15 21:51:04 lol Nov 15 21:51:16 gimme ALl my answers NOW dammit Nov 15 21:52:00 including exact steps! Nov 15 21:52:15 those are always helpful Nov 15 22:31:47 Just wondering if anyone has any experiences with retrieving data from the internet using BBB? Do I have to install a server to use Twitter API and retrieve data from the API? Nov 15 22:33:36 it's the same as retrieving data from the internet on any other linux computer Nov 15 22:39:13 Okay, sorry kinda new to this. I assume that means setting up a server is not necessary. Thank you. Nov 15 23:03:54 hrm is darknighte the GBA development hacker dood ? Nov 15 23:04:25 the one who deliberately released code to brick hundreds of nintendo ds's Nov 15 23:05:01 that was DarkFader Nov 15 23:05:09 oh yea Nov 15 23:05:17 ...probably *c* code Nov 15 23:05:49 davr heh u know of that piece of gba history eh Nov 15 23:08:13 he still active? did the community forgive him or is he shunned still? Nov 15 23:08:25 no idea Nov 15 23:08:42 i dont really follow that community since a couple years Nov 15 23:13:27 people did some pretty crazy stuff with the GBA back in the day. I've been doing some GBA crackpottery myself recently, but I'm a bit late to the party :P Nov 15 23:16:39 go for nintendo DS, that is pretty well documented now. anything past that though I don't think there's been much progress (the dsi and 3ds) Nov 15 23:20:25 I got a flash cart for the GBA without the means to flash to it (for working on some homebrew stuff) so I wrote a DS ROM to flash it instead. That was pretty great. Nov 15 23:21:19 but mostly I was talking about this: https://github.com/jpfau/gbajs Nov 15 23:40:18 hi, is possible connect 4 sensor wireless to 1 AccessPoint on Beagle Board? Nov 15 23:47:47 just powered up my BBB. Noticed with df that it only has ~1.7 GB total disk of which 1.4 GB is used? Nov 15 23:48:06 yep Nov 15 23:48:13 that's a full blown gui interface. Nov 15 23:48:16 sheldonw: what i need? Nov 15 23:48:23 a wifi key on BBB? Nov 15 23:48:41 yeah. also sad that it's only 1.7 and not 2 GB Nov 15 23:48:42 alfaalfa, sorry was referring to beaglepow3r Nov 15 23:48:55 there's 2 partitions Nov 15 23:49:08 oh. devtempfs Nov 15 23:49:19 put ubuntu/debian on if you don't wanna waste time removing packages to slim it down. Nov 15 23:49:27 sheldonw: what you mean? Nov 15 23:49:30 not a bad idea Nov 15 23:49:31 beaglepower? Nov 15 23:50:02 alfaalfa, I am talking to beaglepow3r. Nov 15 23:51:54 sheldonw: what is? Nov 15 23:52:52 read the channel screen dood.. beaglepow3r is another user.. I am answering his question Nov 15 23:53:00 heh Nov 15 23:57:19 sheldonw: channel screen dood..?? Nov 15 23:59:20 thanks for the help sheldonw Nov 15 23:59:30 good luck alfaalfa Nov 16 00:00:19 sheldonw: where i must view? **** ENDING LOGGING AT Sat Nov 16 02:59:59 2013
