**** BEGIN LOGGING AT Thu Jan 30 02:59:58 2014 Jan 30 04:33:52 OK, I'm closer to getting my wifi dongle to work in the production Angstrom A6A distribution. I can see my WLAN adapter under dmesg (shows up as usb 1-1), and I can see my driver under lsmod. But ifconfig still doesn't show me a wlan interface. Ideas? Jan 30 04:34:30 Also, the lsusb comamnd will hang. I can't even kill the process. Jan 30 04:34:53 Ideas? Jan 30 04:37:45 long-shot hunch, if lsusb hangs, you might have somethig hardware wrong. Just checking some assumptions: This dongle works on other machines, including other linux machines? have you tried plugging it in through a powered hub? Jan 30 04:38:19 nope, I haven't done that. Worth a try. Jan 30 04:40:43 hi Jan 30 04:40:46 powered usb hub for the wifi dongle? Jan 30 04:41:00 wifi cards are power hungry Jan 30 04:42:09 yup, it's fully powered. good idea, though Jan 30 04:43:01 just one of those favourite issues :0 Jan 30 04:43:03 :)8 Jan 30 04:44:14 whats Estimated hashe rate mining for Beagleboard-xM ? Jan 30 04:51:34 0.7-0.8kH/s mino233 for cpumining Jan 30 05:00:37 According to windows, my wlan adapter uses the Realtek RTL8188CU driver. In Angstrom, I had installed linux-firmware-rt8188cu. Possibly there's a conflict there. Jan 30 05:00:57 I mean I had installed linux-firmware-rtl8192cu on Angstromn Jan 30 05:01:09 * opkg_install_cmd: Cannot install package linux-firmware-rtl8188cu. Jan 30 05:01:31 maybe I need a different driver. Jan 30 05:01:43 anyway, works in windows, so I think the hardware is okay Jan 30 05:03:46 windows != linux naming or otherwise Jan 30 05:04:04 true Jan 30 05:04:10 realtek are pretty easy to get working .. but yeah, you *will* need a firmware blob for it Jan 30 05:06:23 bonenotes.tumblr.com - iandow Jan 30 05:07:27 thank you!!! Jan 30 05:07:32 yw Jan 30 05:11:58 thanks I know . but What is Estimated hashes BeagleBoard-xM? Jan 30 05:14:04 I'm sorry but I don't understand your question Jan 30 05:17:38 if you have to ask, you're doing it wrong Jan 30 05:38:25 dear ; what is hash rate for this device: http://beagleboard.org/Products/BeagleBoard-xM Jan 30 05:53:29 Good morning, Im testing my BMP085 I2C Pressure/Temperature Sensor, and when i run it from the site or from the shell it works, but when i run it from cloud9 i get all sorts of errors. Is there an obvious step im missing mabey? Jan 30 06:16:15 Nevermind, founr the problem Jan 30 06:16:54 I am connecting two tlv320aic3106 (sound card) to my BBB.The connection is similar to the AUDIO CAPE.In addition MCASP_axr1(p8-31) is connected to the DOUT pin of second TLV320.Basically I wanted to record audio from two codecs.What changes should I do to get it going? Jan 30 06:45:41 how did you connect the 2 codecs? Jan 30 06:46:47 ah ok, it has multiple input pins Jan 30 06:48:14 wonder if he put them on different i2c busses, since otherwise they'd have an address collision Jan 30 06:52:37 ... Jan 30 06:52:38 The I2C interface supports both standard and fast Jan 30 06:52:40 communication modes, and also enables cascading of up to four multiple codecs on the same I2C bus through Jan 30 06:52:41 the use of two pins for addressing (MFP0, MFP1). Jan 30 06:52:43 ... Jan 30 06:54:57 hmm, we have a codec in that the tlv320aic310x family on our board... wasnt even aware of that, although he'd have to muck with the driver to set up addressing pins Jan 30 10:18:53 is that true that when hotplug event is occured kernel send uevent which is catch by udev then it load module for that device then that module create entry or register itself in sysfs and then after that using info in sysfs again udev create device node in /dev directory ? Jan 30 10:21:33 sam__ yes Jan 30 10:27:18 what is procedure after module is loaded ? Is kernel again send udev to create dev node in /dev or something else ? means how system knows module get successessfully loaded ? Jan 30 10:27:41 sam__: there are documents on the web that explain the design of udev Jan 30 10:28:04 sam__: there should be good overview articles on lwn.net Jan 30 10:29:27 hi koth Jan 30 10:29:43 salut woglinde Jan 30 10:29:55 sam__: ldd3 also exaplains stuff in greate detail Jan 30 10:30:43 hitlin37: nope, ldd3 doesnt explain udev Jan 30 10:30:50 hitlin37: ldd3 is older than udev Jan 30 10:31:41 I read about this on lwn.net but sequence for me is not clear so please tell what happens after udev load module ? is kernel agin send send udev ? Jan 30 10:31:56 then read more Jan 30 10:32:19 you didnt read a lot in 4 minutes Jan 30 10:41:46 sam__ why do you have to know it? writing own udev or kernel driver? Jan 30 10:42:02 for kernel driver ? Jan 30 10:42:12 for? Jan 30 10:42:25 for kernel driver Jan 30 10:48:59 what is true dev_node created first or module load first ?Beacause on this pdf ' http://free-electrons.com/doc/udev.pdf ' page 22 they shows dev_node created first and then module is loaded .Excuse for my long dialogs . Jan 30 10:50:18 sam__: nope. the module calls (mostly upon loading) some functions inside the kernel which then trigger dev node creation (through udev) Jan 30 10:51:54 sam__: there are lots of cases where a driver driver does not even create a dev node, for a variety of reasons. Jan 30 10:52:32 so pdf shows wrong or I understand it wrong ? Jan 30 10:53:41 sam__: you understand it wrong Jan 30 10:54:23 sam__: basically you're looking at the wrong use case. they depict the something gets connected - kernel detects - udev matches - loads driver case. Jan 30 10:54:49 sam__: which does not fit the "load driver - create nodes" case Jan 30 10:55:12 "PC load letter" case? Jan 30 10:55:18 or more precisely, the "load driver - create nodes" is what comes *after* that. Jan 30 10:59:40 so "uevent --> udev receive --> laod module --> module itself create device node in /dev through udev " is correct sequence. Jan 30 11:00:03 why does udev even exist? Jan 30 11:00:19 because lennart wanted it so Jan 30 11:00:33 sam__: if it is a device/driver that can be autodetected, then yes. Jan 30 11:00:42 * LetoThe2nd likes udev Jan 30 11:00:42 ogra_: and ubuntu bows to that? Jan 30 11:01:38 (well, not true actually, udev is david zeuthens work iirc) Jan 30 11:02:01 Thank You very much for clearing my concept. Jan 30 11:02:16 av500, well, ubuntu will likely take systemd if debian choses to Jan 30 11:02:27 ubuntu bows to debian ... Jan 30 11:02:58 long bow, short box, composite bow? or even cross bow? Jan 30 11:03:18 converged bow ;) Jan 30 11:03:44 (like a crossbow combined with a gun and a knife) Jan 30 11:03:58 * LetoThe2nd always found compound bows kind of cool. Jan 30 11:04:12 rice bowl Jan 30 11:05:28 i mean, that really has a metal touch to it: http://upload.wikimedia.org/wikipedia/commons/5/59/Compound_Bow_full.jpg Jan 30 11:05:53 lordibow ? Jan 30 11:06:35 \m/ Jan 30 11:12:04 ogra_: not entirely true Jan 30 11:12:16 ogra_: devfs had serious problems with some nasty race conditions Jan 30 11:16:19 KotH, well, i dont think udev was actually a devfs replacement ... iirc it was a replacement for hotplug.sh Jan 30 11:16:35 devfs was kind of a side thing iirc Jan 30 11:18:13 though it resulted in devtmpfs in the end ... which means you could even do without udev at all if thats enabled, just wont have pretty links in /dev that give you nice manes ... and "post module loading configuration" Jan 30 11:18:31 s/manes/names/ Jan 30 11:19:26 ogra_: hmm.. i can neither confirm nor deny Jan 30 11:19:32 ogra_: it's been too long since then Jan 30 11:19:41 ogra_: and i'm an old man who forgets easily Jan 30 11:19:45 well, i cant say i'm 100% sure ... Jan 30 11:19:55 (i think i'm even older) Jan 30 11:20:05 ogra_: how old are you? Jan 30 11:20:13 turning 44 on the 16th Jan 30 11:20:23 ok, you winn Jan 30 11:20:26 :) Jan 30 11:20:31 or lose, depending on your pov :) Jan 30 11:20:37 haha Jan 30 11:25:38 Is there any limitation for changing the mode of pins on P8 header in BBB ? I am not able to change the mode of P8_31.Its stays in mode 7 only.Can some one help me out? Jan 30 11:26:16 did you read SRM and TRM yet? Jan 30 11:26:57 yes i read Jan 30 11:27:46 tbr.. I am trying to change the mode after the board is booted by means of device tree overlays Jan 30 11:30:20 tbr.. And also I have disabled BB-BONELT-HDMI and BB-BONELT-HDMIN Jan 30 11:43:32 tbr..Can the mode be changed.... :-( Jan 30 11:46:45 asdfg: yes, you do it with a device tree overlay Jan 30 11:46:54 asdfg: assuming you are using the 3.8 kernel Jan 30 11:48:44 jackmitchell..thanks for replying.Other pins I can change using device tree overlay Jan 30 11:49:06 asdfg: what is the function of P8_31, adc pins cannot be changed Jan 30 11:49:14 but P8_31,I cannot change to mode 3 Jan 30 11:49:28 asdfg: what does P8_31 currently do? Jan 30 11:49:40 By default its mode 7 gpio Jan 30 11:49:46 and where is that set? Jan 30 11:50:19 Not setting anywhere... Jan 30 11:50:33 on boot up when i checked its showing mode as 7 Jan 30 11:51:28 cat $PINS | grep "8d8" returns pin 54 (44e108d8) 0000002f pinctrl-single Jan 30 11:52:42 and what devicetree overlay are you using to try to set it? Jan 30 11:55:01 in BB-BONE-AUDI-01-00A0.dts , under ' pinctrl-single,pins ' I am adding ' 0x0c8 0x23 ' .. Jan 30 11:58:55 well pin 31 is 0x0d8 for a start Jan 30 11:59:00 jackmitchell .. sorry '0x0d8 0x23 ' is added Jan 30 11:59:07 heh, ok ;) Jan 30 11:59:26 :) Jan 30 11:59:38 can you pastebin the actual devicetree overlay you are using Jan 30 11:59:53 yes ..just a sec Jan 30 12:03:08 http://pastebin.com/aQyjjaAC Jan 30 12:08:43 asdfg: ok, I assume you are re-compiling the dts fragment with dtc Jan 30 12:08:56 asdfg: I'm not sure blank lines are valid so I would remove that Jan 30 12:09:17 asdfg: then as a final measure, I would ensure that the other pins listed in that block are being set to the correct modes Jan 30 12:09:40 asdfg: also check dmesg for any errors when applying the dtb Jan 30 12:13:49 did you find anything wrong in the code Jan 30 12:16:32 12:08:46 - jackmitchell: asdfg: ok, I assume you are re-compiling the dts fragment with dtc Jan 30 12:16:32 12:09:00 - jackmitchell: asdfg: I'm not sure blank lines are valid so I would remove that Jan 30 12:16:32 12:09:20 - jackmitchell: asdfg: then as a final measure, I would ensure that the other pins listed in that block are being set to the correct modes Jan 30 12:16:32 12:09:43 - jackmitchell: asdfg: also check dmesg for any errors when applying the dtb Jan 30 12:26:29 jackmitchell ... dmesg --- http://pastebin.com/5fVieQiB Jan 30 12:27:14 asdfg: [ 178.524148] of_get_named_gpio_flags: can't parse gpios property Jan 30 12:27:19 that maybe looks liek your problem Jan 30 12:27:40 how can i avoid Jan 30 12:27:43 it Jan 30 12:27:46 any clue Jan 30 12:28:00 try moving your new pinmux to above the others and see if the position in dmesg changes Jan 30 12:28:06 have you removed that blank line? Jan 30 12:28:10 yes Jan 30 12:28:29 it says can't parse so it must be different to the others Jan 30 12:28:43 I will try what you said Jan 30 12:35:40 jackmitchell...so .. I hope that ,that error in the dmesg not due to that Jan 30 12:55:47 * mdp sees a fragment and cries Jan 30 13:35:14 hi Jan 30 13:35:29 i have one baglebone black and bb view board Jan 30 13:35:42 when i plug usb otg cable to my computer Jan 30 13:35:49 only the power led is on Jan 30 13:36:16 and i cannot go to storage of board Jan 30 13:36:18 what do you see on the serial console Jan 30 13:36:35 why other led doesnt flash? Jan 30 13:36:41 user leds are off Jan 30 13:38:08 aloo Jan 30 13:38:10 please help me Jan 30 13:38:57 disconnect anything but the usb cable and see if it boots then. also, try reflashing it. Jan 30 13:39:26 how can i reflash it? Jan 30 13:40:22 tom____: http://beagleboard.org/Getting%20Started#update Jan 30 13:40:28 tom____: http://beagleboard.org/latest-images Jan 30 13:43:51 why the user leds are off? Jan 30 13:44:08 probably your board does not boot. Jan 30 13:44:20 so instead of repeating, go debug it!!! Jan 30 13:44:57 i dont know how i should debug it Jan 30 13:45:07 *sigh* i told you Jan 30 13:45:20 disconnect everything else then the usb cable. Jan 30 13:45:24 reflash the board. Jan 30 13:45:29 and KotH told you: Jan 30 13:45:32 do not buy a device you do not know how to debug it Jan 30 13:45:41 get a serial debug cable and look at the bootloader Jan 30 13:46:01 if anything of that is too complicated - please give the board back to whoever gave it to you. Jan 30 13:48:16 TOM____: no private queris! Jan 30 13:48:34 TOM____: ask here so anyone can profit - or help, in case somebody knows. Jan 30 13:48:47 ok Jan 30 13:48:57 i have only the usb otg cable Jan 30 13:49:05 my question is Jan 30 13:49:12 i buy it last might Jan 30 13:49:22 and plug the usb cable to my laptop Jan 30 13:49:26 in first time Jan 30 13:49:37 all leds were flashing Jan 30 13:49:39 but Jan 30 13:49:44 after Jan 30 13:49:57 TOM____: please go buy a new keyboard. Jan 30 13:49:58 unpluging the usb cable form my laptop Jan 30 13:50:07 ley board? Jan 30 13:50:11 key board? Jan 30 13:50:13 TOM____: it seems that your key is broken. Jan 30 13:50:23 whay? Jan 30 13:50:30 why? Jan 30 13:50:31 TOM____: or what might be another reason for pressing ENTER after every single word? Jan 30 13:50:36 no Jan 30 13:50:48 he he Jan 30 13:51:58 what you think about my problem?why have i this problem? Jan 30 13:52:21 i don't know, and as you are not providing information, nowbody can help Jan 30 13:52:30 yes Jan 30 13:52:41 try what i told you, and go buy a serial debug cable as described everywhere on the internet. Jan 30 13:52:52 i have some info about the arm Jan 30 13:53:01 ok Jan 30 13:53:27 TOM____: for your enlightenment: http://elinux.org/Beagleboard:BeagleBone_Black_Serial Jan 30 13:54:53 gone Jan 30 13:56:12 no wonder. but will hit mental ignore now. Jan 30 13:59:31 LetoThe2nd do not think he will come back Jan 30 14:00:08 possible Jan 30 14:33:36 I have been trying to find accurate information on this and have not really found anything concise. Can the beaglebone black handle lipo batteries? If so what kind and can it charge them as well? Jan 30 14:34:54 mistawright: the BBB does not do any kind of battery management, neither as consumer nor loader. it expects 5V, however you produce them is up to you. Jan 30 14:35:38 do not forget the rtc Jan 30 14:35:42 till later Jan 30 14:35:54 LetoThe2nd: I thought it was fairly easy to modify it to do so though. Jan 30 14:36:08 the bbb does have a built in power management ic based on the TI TPS65217C from what i was reading as well Jan 30 14:36:28 tbr: you can certainly beat it into shape by some hardware hackery, but OOTB it does not do AFAIK Jan 30 14:37:17 http://pansenti.wordpress.com/2013/06/01/powering-a-beaglebone-black-with-a-single-cell-li-ion-or-lipo-battery-yes-it-can-be-done-but-there-are-issues/ Jan 30 14:38:26 tbr: kind of supports my saying. Jan 30 14:39:14 sure, I also said that one needs to modify it Jan 30 14:40:05 after $MODIFICATION about every device with two i/o lines can do battery management (granted, the amount of modification varies heavily then.)

Jan 30 16:41:29 Intel Next Unit of Computing Kit D54250WYK - i bought this PC, and one Relay, now from Beagle Board i wanted to do relay to that PC, can i do that like Arduino pin 2, 3 Jan 30 16:41:42 How can i do Arduino like Pin 2 in Beagle board Jan 30 16:43:49 never worked with arduino myself Jan 30 16:45:13 cheers Jan 30 16:45:19 woot! Jan 30 16:51:58 http://i.imgur.com/R7WHRPA.jpg - 1) This is my Day 1 in Beagle Board. Can anyone please advise very basic how can i turn on that light and switch it off via Beagle board please? 2) Yellow light works with 3v or 5v or 9v has + and _ 3) in Beagle board where should i connect those + and _ and what i can do to command it (can i do it via Go language or Python?) Jan 30 16:52:45 <_av500_> you need to drive it Jan 30 16:52:55 <_av500_> you cant connect the light just like that Jan 30 16:53:06 <_av500_> you need a transistor or so as a switch Jan 30 16:53:18 <_av500_> the light needsw more currrent than what a GPIO pin can deliver Jan 30 16:53:23 <_av500_> so you have 2 tasks now: Jan 30 16:53:29 _av500_, i am thinking like my Arduino experience Jan 30 16:53:32 OK Jan 30 16:53:37 <_av500_> 1) learn how to switch a light with a transistor Jan 30 16:53:45 <_av500_> 2) leanr how to toggle a GPIO on BBB Jan 30 16:53:51 <_av500_> both has been done numerous times Jan 30 16:54:38 IamTrying : do *NOT* try to solve both tasks at the same time! Jan 30 16:54:59 sad to say, engineering curricula tend to be several semesters because the volume of knowledge fills more than a pamphlet Jan 30 16:56:13 _av500_, toggle GPIO with /dev/mem or other method? Jan 30 16:56:15 OK - thank you _av500_ , CareBear\ will solve it. But just want to clear my concept a bit. Jan 30 16:56:41 Can i program in the Beagle with my Go compiler or Python 2.7 or i need to use something like Arduino ? Jan 30 16:57:45 <_av500_> you can use python Jan 30 16:57:49 <_av500_> no idea if there is go for it Jan 30 16:57:50 it is a Linux system Jan 30 16:58:36 OK - Thank you _av500_ Go i installed working FYI Jan 30 16:58:45 Now next step is to hack the wiring Jan 30 16:58:53 NO! Jan 30 16:59:00 LISTEN TO THE ADVICE THAT YOU GET Jan 30 16:59:18 OK - but just want to understand what is those BLACK pin slots? Jan 30 16:59:18 IamTrying : _av500_ explained to you that you have two tasks Jan 30 16:59:25 you do not need to understand that yet Jan 30 16:59:43 CareBear\, in the Beagle board it has black pin slots what are those, where can i find there definations like which pin is what. Jan 30 17:00:24 even if you did understand what they are you can not use that understanding for anything at this point Jan 30 17:00:52 IamTrying : what do you want to accomplish in the longer term? Jan 30 17:00:52 <_av500_> everything is public Jan 30 17:00:57 <_av500_> the schematic Jan 30 17:01:02 <_av500_> the CPU manual Jan 30 17:01:05 <_av500_> the BBB manual Jan 30 17:01:39 <_av500_> such docs Jan 30 17:01:42 <_av500_> much public Jan 30 17:01:44 <_av500_> very wow Jan 30 17:01:48 very wow! Jan 30 17:01:55 CareBear\, Write a Helicopter this weekend got Motors, BAttery, and Beagle Jan 30 17:02:04 IamTrying : forget about it. Jan 30 17:02:23 CareBear\, Why ? have done it with Arduino whats wrong with Beagle ? Jan 30 17:02:51 IamTrying : nothing is wrong with beagle. the assumptions you are making about the beagle are wrong. Jan 30 17:04:14 CareBear\, can i do this with Beagle ? The main reason i need it today. was this http://www.coocox.org/driver_repo/65ab980d-09b5-4fdb-b4cf-7373ed756a78/doc/eular.gif Jan 30 17:05:27 IamTrying : how does that work? Jan 30 17:07:50 CareBear\, They say: The InvenSense MPU-6050 sensor contains a MEMS accelerometer and a MEMS gyro in a single chip. It is very accurate, as it contains 16-bits analog to digital conversion hardware for each channel. Therefor it captures the x, y, and z channel at the same time. Jan 30 17:08:13 IamTrying : what do you say? Jan 30 17:08:20 IamTrying : do you understand any of it? Jan 30 17:08:36 CareBear\, How can i wire it with Beagle board? Jan 30 17:08:57 IamTrying : you can not wire anything unless you already understand why it would work. Jan 30 17:09:33 IamTrying : and if you understand why it would work then you can also quite easily find out *how* it will work with the beagle - because of all the public documentation Jan 30 17:09:50 IamTrying : this is the essence of engineering. Jan 30 17:09:59 IamTrying : or development, if you prefer Jan 30 17:10:10 IamTrying : copypasting code from hipstercircuits.com is not Jan 30 17:10:46 * CareBear\ is off. later! Jan 30 17:13:21 Beagle board is not user friendly, its trying to make itself more complicated, when a user start, he should have first impression that it works and its fun Jan 30 17:13:30 I do not get that feelings with Beagle board Jan 30 17:13:49 When i started Arduino, it was fun and exciting cause it works in Day 1 Jan 30 17:14:03 Beagle board does not work and not friendly / not well documented Jan 30 17:14:25 you sound like you wanted a raspberry pi insteadf Jan 30 17:14:27 you sound like you wanted a raspberry pi instead Jan 30 17:15:03 User experience is not nice for Day 1, we want to have fun in Day 1 like all works not like go and read the book has 900 pages. Jan 30 17:15:58 Look at Go language it simply works in 1 minute. Look at Arduino its fun. It lets build something and make it more exciting. That user experience is ignored in Beagle board. Jan 30 17:16:15 IamTrying, I am getting one soon myself and have been looking at tutorials etc. I have been using linux for a while so I dont see it as being all that complicated. Jan 30 17:16:49 Specially mistawright , you have to be non-technical person when making something like Beagle board. Jan 30 17:17:18 mistawright, no knowledge technically and just make yourself a ordinary person. Then if you start Beagle board its a nightmare. Jan 30 17:18:01 I would consider the beaglebone black a great product for someone that needs more functionality than the pi. I have a raspberry pi I was given for free at work and find it to be ok. The beaglebone black on the other hand is a great platform to start with Jan 30 17:19:25 the typical person wouldnt be looking at the beaglebone black. I was waiting on an arduino tre because I have been playing around with arduino's but it is literally an arduino with a beaglebone black slapped in the middle. So I am definitely getting the beaglebone black and will be excited to see how it works for my quadcopter project Jan 30 17:19:50 mistawright, OK - but 99% users coming from Arduino or Linux or Basic language skills. Whats to write in Day 1 something which works, my experience is bad with Beagle Board. I thought the user experience with Beagle would be much more simple and more friendly (compared to PI, Arduino) Jan 30 17:20:07 IamTrying, do some basic tutorials Jan 30 17:20:21 such as controlling the leds on the device itself Jan 30 17:20:33 mistawright, I am doing. But first impression is the best impression, i got a feelings like Beagle board is complex. Jan 30 17:21:21 You only feel that way because the beaglebone community is not as large as the arduino or pi community. Jan 30 17:21:57 Right. mistawright, some poeple make the new comer scared which should not happen Jan 30 17:22:37 Any way thank you mistawright nice talking to you. Are you expert or just started like me with Beagle Jan 30 17:22:58 I have been trying to order a beaglebone black for months and walked into my local radioshack and saw it on the shelves and was lucky enough to have them hold it for me. I will be trading my galaxy s3 that needs the lens replaced for a $100 dollar credit and walk out with a free beaglebone black. my raspberry pi just sits most of the time Jan 30 17:23:59 OK - mistawright - what makes you excited on Beagle board? Jan 30 17:24:31 IamTrying, starting out. I want to build a quadcopter with a beaglebone black on board. Exploring the idea of building my own cape to make hooking up servos and esc's a breeze. I am not too scared of the programming side of things mostly the electronics portion as I have already fried an arduino nano playing around Jan 30 17:25:08 I saw an amazing video on youtube about the beaglebone black and wowee and it made me want to get the board even more Jan 30 17:25:33 mistawright, Cool, i want to do the same thing like you. Jan 30 17:25:45 mistawright, but why Beagle board you can do it with Arduino too Jan 30 17:27:03 mistawright, 6 motor, 6 blade, better power source, IR control for all those Quadcopter Arduino is enough. Beagle board i will need to do Gstreamer, OpenGL etc Jan 30 17:27:09 IamTrying, http://www.youtube.com/watch?v=neaFAZHc8F0, I like the idea of it being linux powered. I am a gentoo linux fanatic so sitting down and tinkering doesnt bother me Jan 30 17:28:38 I am building an arduino nano powered electric ducted fan jet that should be flown this weekend. it uses apc220 rf modules for control and two arduino nano's. I will be using the same apc220 module for the beaglebone black as well. Jan 30 17:29:33 You want realtime for flight control Jan 30 17:30:08 You can run it on BBB but i wouldnt so it on linux Jan 30 17:30:39 Vaizki_, would you not recommend the bbb for this, would it be better to use an arduino connected to the bbb through i2c? Jan 30 17:31:37 mistawright, what is the difference between Intel NUC and Beagle board if you have to include Arduino. I would do all in one with Beagle but its so complicated they did not have a simple documentation like Arduino Jan 30 17:32:00 Yea an arduino for realtime control and bbb for General purpose computing would work Jan 30 17:32:36 IamTrying, intel nuc is an x86 pc. bbb is arm soc Jan 30 17:32:58 mistawright, well 64-bit is much better then ARM Jan 30 17:33:02 you can do hell lot Jan 30 17:33:29 I am running intel NUC and at the same time i am running ARM, ARM is slow Jan 30 17:33:37 Intel NUC is fastest and can do a lot Jan 30 17:33:49 Eh Jan 30 17:34:06 Vaizki_, so I should be able to send serial commands to the bbb through my rf module and then have it pass those values to the arduino for control. But would it be better to directly control through the arduino and use the bbb for adjustments during flight? Jan 30 17:34:50 IamTrying, you'll get battery life out of the beaglebone black if you are going for a mobile device Jan 30 17:35:09 Well I'm no expert but for quad stabilization etc you are better off with a mcu or rtos than normal Linux Jan 30 17:35:11 mistawright, you are right battery is a big problem Jan 30 17:35:26 Gumstick maybe mistawright Jan 30 17:36:00 Vaizki_, would the pru's not work in this instance? I am not sure what the pru on the beaglebone black can be used for yet Jan 30 17:37:11 mistawright, use Intel NUC and over ethernet send commands to Arduino Jan 30 17:37:19 Yes they would work Jan 30 17:37:47 Pru programming is not well documented though Jan 30 17:38:06 And you will be doing it in assembler Jan 30 17:38:41 I will never use complex method, use something simple can be community friendly and others can help you mistawright Jan 30 17:39:02 Microsoft said: i will hire a stupid, lazy guy, cause he will make the software in his lazy and easy way. Jan 30 17:39:26 mistawright, easiest would be Arduino and Beagle over Ethernet Jan 30 17:39:54 IamTrying, better stop trying Jan 30 17:40:02 IamTrying, I am all for the learning curve though. I want to get better with my programming and this is something I can have fun with Jan 30 17:40:03 go back to your Arduino Jan 30 17:40:24 IamTrying, bbb + arduino through i2c or serial would be better for me Jan 30 17:40:45 Or get a px4 :) Jan 30 17:41:04 Vaizki_, the pistol? Jan 30 17:41:47 mistawright, serial you are increasing weight, try IR or wifi and maybe much better use Crestron/Extron Jan 30 17:42:52 IamTrying, how would serial increase weight? I could do serial over usb on the bbb. but i2c would be better Jan 30 17:43:40 Px4 pixhawk Jan 30 17:44:15 Iamtryingbutnothelping Jan 30 17:44:24 lol Jan 30 17:44:45 would the bbb with a real time clock added through i2c not be enough to run rtos on the bbb? Jan 30 17:48:34 looks like my understanding of rtos was off and i have now educated myself Jan 30 17:50:01 mistawright, what is the purpose of using then Beagle board why and how is it helping you? Jan 30 17:50:16 I think i just wasted buying Beagle board. Jan 30 17:50:35 I cant wire it with external hardwares and do the same thing like i can do with Arduino. Jan 30 17:50:55 IamTrying, it is helping me to learn to program for embedded hardware. And it can do everything you have said so far Jan 30 17:51:38 IamTrying, http://learn.adafruit.com/category/beaglebone here is some simple things to get you started playing around with Jan 30 17:52:11 OK - thank you mistawright , good luck with your project Jan 30 17:52:24 you just need to know how to interact with it. I spent a week pissed off thinking I had bought shoddy rf modules. turns out I had the pins hooked up incorrectly Jan 30 17:52:47 IamTrying, you can always send that bbb to me if you really dont want it ;) Jan 30 17:53:24 mistawright, http://learn.adafruit.com/category/beaglebone - man this link is a treasure i was looking for Jan 30 17:53:32 mistawright, i can do all i wanted with it!! wow Jan 30 17:54:21 "Whee" Jan 30 17:54:29 IamTrying, you can do a lot with it. I talk crap about my pi but its because I havent done anything with it, I fell in love with the bbb when i first heard of it. so I may use the pi for another project Jan 30 17:55:14 Pi is a set top box chip Jan 30 17:55:23 Excellent. See how you motivated me, showing me the excellent way to learn it. I love doing it and then learn it. Jan 30 17:55:26 thanks mistawright Jan 30 17:57:29 Vaizki_, exactly and it sucks at that too. Jan 30 17:58:30 Well it was designed to run simple Python scripts written by school kids Jan 30 17:58:51 It's remarkably good considering that Jan 30 18:00:06 exactly. people just seem to think thats its the best thing for every application. Jan 30 18:08:54 Those people are not on this channel fortunately Jan 30 19:36:37 So I have been doing some reading/research and have come across some projects that use the beaglebone black's pru for servo control. with that being said would there be any reason to use an arduino with my beaglebone black for a quadcopter? Jan 30 19:40:45 mistawright, there is also specialized hardware to control servos iirc Jan 30 19:40:51 (within the am335x) Jan 30 19:42:26 Russ, I wanted to control a quadcopter and was given the advice to use the arduino for control and have the black control the arduino. Jan 30 19:42:27 You're going to want to work on your power management, if you're using a BBB on a QC. They're not exactly "low power". That's why there are boards optimized for flight control. Jan 30 19:43:54 I don't mind powering the beaglebone itself from a small single cell lipo and have the motors run from there own power source. Jan 30 19:44:34 Well, sure, you can do that. But that's more weight. More weight == decreased flight time. Jan 30 19:45:53 true enough. I would assume that a 3s 2600ma lipo would be able to power a quadcopter and the beaglebone for a 15 minute flight. Jan 30 19:46:17 Not sure if there's any flight control software that runs under linux. A lot of people use boards based on some variant of an ARM-7 core, like an STM32Fxxx part. Jan 30 19:46:43 You're carrying a lot of extra weight and power budget in flying something like a BBB, rather than a dedicated controller. Jan 30 19:48:04 jcw__, all i want is direct control of the servo's and esc through the beagle bone black which will be receiving input through serial in the form of communication through an apc220 rf module Jan 30 19:48:12 Those boards also have all the sensors, interface logic and what not to drive the ESCs. Jan 30 19:50:20 It may work, but I doubt you'll get the stability to keep the platform in the air without an on-board flight controller. THEN you use your data channel to drive it. Jan 30 20:03:35 wouldn't using the pru's eliminate those issues? Jan 30 20:09:01 How so? You still need a flight control algorithm. Jan 30 20:09:33 Basically, you want to be able to maintain a steady platform, and then provide offsetting inputs to cause it move in a given direction. Jan 30 20:24:43 Looking for a little wifi / wlan / 802.11 help here... I'm trying to enable realtek wifi adapter on my beaglebone. I can see my wlan0 device under ifconfig, but it's not connecting to any network. Jan 30 20:25:18 I've specified Type=wifi, Name=(my ssid), Security=wpa, and Passphrase=(my passphrase) in /var/lib/connman/wifi.config Jan 30 20:25:28 any ideas what I'm missing?? Jan 30 20:25:52 firmware? Jan 30 20:26:19 you''l need some app to manage wifi security eg iwconfig or wpa_supplicant and/or networkmanager/wicd Jan 30 20:26:24 I've installed the driver, using this as a guide: WebUser:fh7SkVT4@23.251.207.30/cn/wlan/ Jan 30 20:27:06 what does 'dmesg' say about the rtnnnn driver? Jan 30 20:27:40 The command `iwconfig wlan0 essid (my ssid)` gives me this error: SET failed on device wlan0 ; Operation not permitted. Jan 30 20:27:45 yup, dmesg shows my driver. excerpt: [ 14.175976] usbcore: registered new interface driver rtl8192cu Jan 30 20:28:07 iandow: did you reset connman after making the wifi.config file? Jan 30 20:28:29 rfkill perhaps Jan 30 20:28:43 lol @ conman .. awseome name for daemon lol Jan 30 20:28:44 I rebooted... so assume that would reset connman Jan 30 20:29:38 i'm not familiar with rfkill. I'll look into that Jan 30 20:35:01 `rfkill list` is coming up with nothing Jan 30 20:35:21
