**** BEGIN LOGGING AT Fri Jan 24 02:59:59 2014 Jan 24 03:04:59 hello Jan 24 03:05:22 does anyone know how to program BBB from a windows box? Jan 24 04:31:05 how can i connect the touch screen display with beaglebone black Jan 24 05:17:32 hello Jan 24 05:32:38 world Jan 24 13:38:05 Hi, I try to get ADC on BBB running in continuos mode: Jan 24 13:38:53 Kernel 3.8.13 (Ubuntu) Jan 24 13:39:25 if i try to enable i get this: Jan 24 13:40:07 echo 1 > /sys/bus/iio/devices/iio:device0/buffer/enable Jan 24 13:40:23 bash: echo: write error: Invalid argument Jan 24 13:40:32 any solution? Jan 24 13:40:56 spoonox: can please "cat" the contents of the file? Jan 24 13:41:08 0 Jan 24 13:41:40 are you running this as root? or with sudo? Jan 24 13:41:54 cat /sys/bus/iio/devices/iio:device0/buffer/enable Jan 24 13:41:56 0 Jan 24 13:42:22 i run this as user and sudo Jan 24 13:43:01 both fail Jan 24 13:43:18 maybe try "sudo su" and then the command? it's a looooonnng shot...but who knows :) Jan 24 13:43:23 sudo isn't the same as being root :) Jan 24 13:43:36 esp with cat/echo Jan 24 13:43:42 don't you need to set up your iio scan mask first? Jan 24 13:43:51 i've tried this also in sudo su mode Jan 24 13:43:55 fail again Jan 24 13:44:05 then mdp probbaly has ap oint ... Jan 24 13:44:19 enabling the buffer will fail if you have not set up the scan mask in any iio driver Jan 24 13:44:20 iio scan mask? Jan 24 13:45:21 well, that's the driver terminology for the allowable elements..but it's scan_elements in sysfs Jan 24 13:45:33 i ve set /sys/devices/ocp.3/44e0d000.tscadc/tiadc/iio:device0/scan_elements/in_voltage0_en to 1 Jan 24 13:45:39 https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-bus-iio Jan 24 13:45:47 ok Jan 24 13:45:57 good Jan 24 13:47:36 so there is no more to set from my noob point of view Jan 24 13:47:43 do you guys know, if I can use a AC adapter with 6V and 2100mA for the BBB? Jan 24 13:48:25 spiderpigloki .. given the BBB uses 5V, and is sensitive to fluctuations .. I'd say No. Jan 24 13:49:43 mdp any other hint? Jan 24 13:50:04 I've never used the adc on am335x so can't think of something else Jan 24 13:50:15 I've worked on another iio driver so that came to mind Jan 24 13:50:25 stt_michael: yeah I suspected, but I saw diffenrent recomandations for the Amps (1500 mA up to 2000mA) so I thought a certain tolerance might also work for the Volts ;) THX though Jan 24 13:50:30 ok thx Jan 24 13:51:04 spiderpigloki .. amps, upwards, yes .. volts .. absolutely not :) Jan 24 13:51:21 you're likely to cause irrepairable damage ! Jan 24 13:52:48 stt_michael: yeah I figured one of them is bad, when too high :D good thing I asked xD Jan 24 13:53:16 indeed :) Jan 24 13:54:09 if it runs good at 5V, imagine how good it will run at 10V Jan 24 13:57:27 10000mV is more impressive Jan 24 13:58:24 spoonox, you might also have to set up the current_trigger Jan 24 13:59:54 mdp: i hope also stable at the 10ppm level Jan 24 14:00:34 10000mppm :) Jan 24 14:00:52 ah.. right Jan 24 14:01:50 mdp: measured with a HP3458 or a fluke 8505? Jan 24 14:01:59 8508* Jan 24 14:03:06 hehe..8508..I'd like somebody buy me that for the home office Jan 24 14:03:36 mdp: get a HP3458, it's cheaper Jan 24 14:04:17 get a KeySight8888 Jan 24 14:04:19 its the best Jan 24 14:11:20 just build one! Jan 24 14:16:24 ordered from aliexpress Jan 24 14:19:15 av500, I will wait until they change names again Jan 24 15:02:04 spoonox, http://beagleboard-gsoc13.blogspot.com/2013/07/sampling-analogue-signals-using-adc-on.html Jan 24 15:02:16 spoonox, see trigger setup Jan 24 15:27:38 hello! i was wondering if it was possible to use the usb2.0 or the mini usb on the beaglebone black as serial communication to an android device using their usb2.0 port. I've tried to connect the usb ports together, but the beaglebone dones't detect the android system. If i use the micorusb port on the beaglebone can recgonize it as ttyACM0 port, but i don't want to use that port because that will be used as the main charging station Jan 24 15:28:39 phase0: i think you confuse a few terms there Jan 24 15:28:46 phase0: 1) there is no usb2.0 port Jan 24 15:29:12 phase0: there are only sockets for usb, they are called A, B, mini-A, mini-B, micro-A, micro-B Jan 24 15:29:47 phase0: 2) the bbb does not charge anything, there is nothing to charge to begin with Jan 24 15:30:07 the BBB won't charge a device either lol Jan 24 15:30:21 via usb or anything Jan 24 15:37:51 the charging would come from another external source Jan 24 15:38:45 hmm Jan 24 15:38:46 okay Jan 24 15:41:15 would two USB A be able to communicate automaically? or would there need to be a driver that has to be written first? Jan 24 15:41:49 if you connect two USB A together, then, most likely, you are doing something wrong Jan 24 15:42:01 usb has always a host and a device side Jan 24 15:42:27 the host controls the bus while the device answers the hosts requests Jan 24 15:42:38 A is the host side, B is the device side Jan 24 15:42:51 if you connect two A's together, you connect two hosts together Jan 24 15:43:11 both try to be master of the bus and shout at each other until the world ends Jan 24 15:43:26 Ohh, alright, so thats why the when using the MicroB port on the android and the usbA on the beaglebone, it gets detected Jan 24 15:44:23 also consider what happens to the power line in that arangement, if one end is powered off Jan 24 15:46:22 that's usually not a problem Jan 24 15:46:30 unless you try to power a whole PC from usb Jan 24 15:46:39 then you might consider buying a new BBB Jan 24 15:47:33 phase0: hint: read up on the stuf you are using, at least the basics Jan 24 15:47:34 which is why I mentioned it :) Ostensibly, host controllers are supposed to have power protection. Often they don't, or sometimes stupidity overwhelms it. Jan 24 15:47:41 phase0: otherwise you might fry up everything Jan 24 15:48:09 phase0: or you behave like those infinite monkeys smashing BBBs together until they form a bitcoin mining cluster Jan 24 15:49:30 KotH .. didn't think there was enough computational power in the am335x cpu :p Jan 24 15:51:41 haha, thhanks so much for the information, i really appreciate it Jan 24 15:53:30 phase0 .. what is it you're trying to achieve with multiple USBs? Jan 24 15:53:46 i ahve some sensors connected to the beaglebone and wanted to do processing on it Jan 24 15:53:47 The BBB has one client and one host USB port available Jan 24 15:53:56 and then send the data to the android Jan 24 15:54:06 to control a game Jan 24 15:54:50 phase0 .. does the android fetch the data, or expect the data? Jan 24 15:55:12 ie. which end is controlling the data transfer? Jan 24 15:56:56 the android is expecting the data Jan 24 15:57:15 but, the android performs the handshake to tell the bbb to send data Jan 24 15:57:42 so the BBB is acting as client, not host then Jan 24 15:58:40 yup Jan 24 16:00:05 you'll certainly need to do some homework on USB then .. the factory image creates a network/storage class over USB as a client device on the mini-B port Jan 24 16:02:33 i currenlt have a ubuntu image on it, so i can only get the mini-b port to power it Jan 24 16:08:02 phase0 .. are you hoping the android will run the BBB?! Jan 24 16:16:31 haha!! no! the current build of the ubuntu image dones't have the network driver over the mini b, so the only reason i use that port is for power coming from my pc. so i need to repurpose the mini-b on the bbb to act as a client mode for usb Jan 24 16:18:52 correct Jan 24 16:19:32 if you wish to use usb_ethernet_gadget/usb_storage_gadget, that is absolutely right Jan 24 16:19:42 you may find you need to build a custom kernel Jan 24 16:19:57 the usb gadget options are under usb drivers iirc Jan 24 16:20:45 ohh. okay. thanks stt! i'll have to look into that. thanks a lot for you help. Jan 24 16:22:11 hi. I'm trying to program gpio in beagle board in bare metal. BeagleBoard system reference manual in part 8.6.8 Pin muxing tells that there are 8 modes for each pin on the board and they can be configured, particularly as gpio pins. But I can't find document where is said how can I configure this. Could you point me in the document, please? Jan 24 16:23:40 hi all, Jan 24 16:23:42 is it in OMAP35x Applications Processor Technical Reference Manual? Jan 24 16:24:10 anyone can tell me the dimensions of a bbb? i'd like to build a wopr case for it Jan 24 16:26:56 http://elinux.org/images/2/2b/Features.jpg 3.4x2.1 Jan 24 16:28:06 ragnar76: ^ Jan 24 16:29:54 mcsim .. you'll need to work out a Device-Tree file if your kernel is >3.8 to configure the pinmuxes Jan 24 16:30:13 ragnar76 .. it's in the System Reference Menual for the BBB Jan 24 16:31:35 ragnar76 .. check out http://elinux.org/Beagleboard:BeagleBoneBlack#Hardware_Files Jan 24 16:32:25 mcsim .. http://learn.adafruit.com/introduction-to-the-beaglebone-black-device-tree Jan 24 16:32:59 i have the pdf open but i canot work with inches. what are 3,4 in centimeter? Jan 24 16:33:11 ragnar76 .. divide by 25.4 Jan 24 16:33:26 ie .. 25.4mm = 1in Jan 24 16:33:50 or multiply :) Jan 24 16:34:39 or just learn the metric system Jan 24 16:35:01 Humpelst1lzchen .. he knows the metric syste m .. its the american imperial system thats a nuisance for the ISO-adhering world Jan 24 16:35:16 metric, that's like milliinches, right? Jan 24 16:35:28 thousandths .. if you must :p Jan 24 16:35:30 centimiles Jan 24 16:35:32 or 'thou' Jan 24 16:35:48 microquarts Jan 24 16:36:11 * stt_michael mutters somethinig about ignorant americans .. xD Jan 24 16:37:39 +1 Jan 24 16:39:47 stt_michael: I don't use linux. I have my own kernel. But seems I found what I need: part 7.4.4.3 from OMAP35x Applications Processor Technical Reference Manual Jan 24 16:40:00 ah gotcha Jan 24 16:40:28 TRM is the Ultimate Reference :p Jan 24 16:40:51 BBB SRM -> TI SRM -> TI TRM I believe. Jan 24 16:41:03 increasing order of technicality Jan 24 16:42:08 stt_michael: i hope :) Otherwise what could be larger than 3.5k pages of documentation? Jan 24 16:42:44 I've only heard of it .. Never read it .. hope I never do! Jan 24 16:46:57 no Jan 24 16:47:25 brain -> google -> SRM -> TRM -> DS Jan 24 16:48:29 same diff. :p Jan 24 16:48:45 * stt_michael -> pub :D Jan 24 16:49:16 some may argue for google first and I can't deny it Jan 24 17:10:36 Hello guys, i have a question about my BB-XM rev B Jan 24 17:10:53 ask away ... Jan 24 17:11:17 I want to connect 2 webcam, but the USB bus is already full. Can i use the BUS 2 to connect the other webcam? Jan 24 17:11:42 ramsus .. not easily .. you'd be better (and cheaper) connecting a USB hub to your USB port, and connecting both to that Jan 24 17:12:15 ramsus .. to use the mini-USB you'd have ot make some modifications to the board, and to the driver Jan 24 17:12:44 stt_michael: oh ok, so can i resolve with usb hub, right? Jan 24 17:13:06 What is the current recommended kernel version for the BB-Xm ? Jan 24 17:13:16 ramsus .. that would be my approach, yes .. I don't forsee any problems .. but you might want to go for a powered hub, just in case. Jan 24 17:13:37 Thanks stt_michael Jan 24 17:13:46 Have a nice day everyone Jan 24 17:14:38 awozniak .. its largely up to you .. I think the TI ones are stuck at 3.8 official .. but there are alternative builds around eg eewiki.net/display/linuxonarm Jan 24 17:15:27 awozniak, I recommend 3.13-rc8 atm Jan 24 17:15:49 *cough* Jan 24 17:16:03 well, 3.13 now ;) Jan 24 17:16:08 mdp: why do I suddenly feel like you're yanking my chain? Jan 24 17:16:12 3.13 sounds good :D Jan 24 17:16:21 I don't know...I'm not Jan 24 17:16:57 try the real kernel first, then go to the strange forks if there's something missing that you need Jan 24 17:28:17 Has anyone had an issue of populating the IP 192..etc witht their BBB? Jan 24 17:28:26 populating?! Jan 24 17:28:29 sorry Jan 24 17:28:33 having the webpage shown Jan 24 17:28:50 i have installed the rules and reloaded everything, however, I am still not able to get the page to show up Jan 24 17:28:51 bbl .. pub calling :D Jan 24 17:29:45 and when i do a ifconfig i am not seeing 192.168.7.2 as eth1 or eth0 Jan 24 17:30:19 i am at a loss right now :( Jan 24 17:31:00 mdp stt_michael: 3.8.??? I'm having trouble finding a link for the official supported kernel Jan 24 17:31:44 geek242 Jan 24 17:33:05 3.13 is the kernel I support ;) Jan 24 17:55:04 Are there any schematics for the new WL1835MOD cape? The boardzoo page (http://boardzoo.com/index.php/catalog/product/view/id/146/category/8#.UuKns7Qo670) doesn't show anything Jan 24 17:57:18 etch: that cape is pretty much unsupported due to lack of software from TI and the fact that the design precludes the use of virtually any other cape at the same time Jan 24 17:57:38 etch: in addition, to use it on black, you have to disable the emmc, hdmi and hdmi audio Jan 24 17:57:54 etch: you can get a copy of the schematic by emailing support@circuitco.com Jan 24 17:59:32 prpplague: Thanks. We're using it on a test platform based on the BB and wanted to see what they used for a level shifter. Didn't know if it was the same as the TiWi cape Jan 24 17:59:41 prpplague: i'll email them though Jan 24 17:59:58 etch: it uses TXS0108 for level shifting Jan 24 18:00:04 <_av500_> of course Jan 24 18:00:34 thanks Jan 24 18:24:20 etch: schematics on the way Jan 24 19:11:13 whee, google services dead ? Jan 24 19:12:06 <_av500_> yes Jan 24 19:12:15 there status dashboard is useless. ;0 Jan 24 19:12:56 Hello, i have a problem with my BB-XM rev.B Jan 24 19:13:22 I cant' connect 2 webcam (also using an external HUB) because i get this message: bv4l2: error turning on stream: No space left on device Jan 24 19:13:48 "No space left..." is not an SD problem, i have enough space (df -h) Jan 24 19:13:56 <_av500_> nothing to do with sd card Jan 24 19:14:01 <_av500_> its astupid error message Jan 24 19:14:04 ramsus, probally ran out of usb bandwidth.. it's only one port.. Jan 24 19:14:06 <_av500_> inside v4l2 Jan 24 19:14:30 rcn-ee: yeah, i searched on google and this message is for USB bandwidth Jan 24 19:14:41 so the fix.. use one.. ;) Jan 24 19:14:56 My question is: can i attach the other webcam on the miniUSB controller? have they different bus? Jan 24 19:15:06 <_av500_> yes Jan 24 19:15:13 <_av500_> EHCI vs musb Jan 24 19:15:22 <_av500_> you have to get the musb into host mode Jan 24 19:15:40 and pray your devices works with the musb ip.. Jan 24 19:15:57 Ok, no problem about that. There are any kind of cables to swith USB -> mUSB? Jan 24 19:16:14 <_av500_> you would need a cable that grounds the ID pin Jan 24 19:16:54 uhm ok. I will search it. Thanks for the informations guys Jan 24 19:24:54 that's a standard OTD cable, right? Jan 24 19:24:58 er, OTG Jan 24 19:41:13 http://www.reddit.com/r/IAmA/comments/1w1y5m/we_are_the_google_site_reliability_engineering/ Jan 24 19:41:16 * ogra_ grins Jan 24 19:41:41 timing rocks :) Jan 24 19:48:28 <_av500_> :) Jan 24 19:52:56 anyone know if i can AirPrint with a beagle bone black? Jan 24 20:01:22 s/beagle bone black/Linux/ Jan 24 20:01:51 not a beagle question even though you phrased it as such Jan 24 20:01:53 mdp: i was about to say the same thing, but that person left the channel Jan 24 20:01:56 go search google Jan 24 20:02:01 fsck Jan 24 20:02:03 drive bys Jan 24 20:02:06 POS Jan 24 20:02:17 prpplague, glad to see them gone Jan 24 20:07:55 so how much wood can the beagle bone black chuck if the beagle bone black can chuck wood? Jan 24 20:09:54 ds2: that depends how much tolerance you have for hand-writing PRU code to mash together a woodchucker routine :P Jan 24 20:11:39 myself: that will be very high soon Jan 24 20:11:51 the BBB needs composite out Jan 24 20:12:04 oh dear Jan 24 20:12:06 and I am gearing up to cough up some PRU code for that Jan 24 20:12:18 you ARE thinking what I thought you were thinking Jan 24 20:12:30 that'll chuck some scanlines, alright Jan 24 20:12:44 a 200MHz PRU should be able to do this without breaking a sweat Jan 24 20:12:55 the question I am pondering is - color or no color Jan 24 20:13:38 what is annoying is the small amount of local SRAM Jan 24 20:13:41 there are certainly plenty of examples for other platforms, too.. Jan 24 20:13:57 *nod* Jan 24 20:14:29 there is the all hardware approach Jan 24 20:15:01 but I am not in the mood to layout and assemble a PCB Jan 24 20:15:04 hey sakoman! Jan 24 20:17:54 nah, bitbanging a resistor DAC is cooler Jan 24 20:18:01 +1 Jan 24 20:18:05 bitbang for life Jan 24 20:19:09 anyone want to volunteer to write a USB device code for the PRU? Jan 24 20:19:19 <_av500_> lol Jan 24 20:19:21 <_av500_> you Jan 24 20:19:22 should be more reliable then the current MUSB stuff ;) Jan 24 20:19:36 <_av500_> ds2: with 200mhz PRU? Jan 24 20:19:38 <_av500_> high speed? Jan 24 20:20:37 _av500_: they are doing it on AVRs and MSP430's Jan 24 20:20:41 no not HS Jan 24 20:20:52 just the 1.5M mode Jan 24 20:23:32 ds2, I'm told the musb is now flawless on mainline, fwiw Jan 24 20:23:49 ymmv ;) Jan 24 20:23:54 :P Jan 24 20:24:01 mdp: on which HW? ;) Jan 24 20:24:17 BBB Jan 24 20:25:57 I'd find it more reassuring if you had said BBC or BBX Jan 24 20:28:04 ;) Jan 24 20:31:52 or at least something that brings out OTG Jan 24 20:39:27 mdp, hard to be flawless, when new patches show up... http://www.spinics.net/lists/linux-usb/msg101488.html ;) Jan 24 20:47:26 rcn-ee, ;) Jan 24 20:50:50 rcn-ee, when will this kernel be done? Jan 24 20:52:19 <_av500_> mdp: the ke-rcn-ee-l? Jan 24 20:58:04 it's never done.. ;) Jan 24 20:58:25 rcn-ee: making the donuts? Jan 24 20:59:47 trying too.. but the snow keeps getting deeper and truck keeps getting stuck... Jan 24 21:08:09 rcn-ee, maybe with 3.15 ;) Jan 24 22:34:53 "60" ? Jan 24 23:01:18 Got my 1st BBB today :) How long should the first boot take after re-flashing the emmc to Angstrom? Jan 24 23:08:58 Got my 1st BBB today :) How long should the first boot take after re-flashing the emmc to Angstrom? Jan 24 23:11:28 It's ok, worked on the third attempt. Jan 24 23:43:37 I'm having an issue connecting the beaglebone HDMI-DVI converter to a monitor. Any ideas what the issue could be. The beaglebone icon comes up, but then it goes away and the monitor goes to sleep. Jan 24 23:54:19 bad cable, bad adaptor Jan 24 23:54:31 oh, he left, nevermind Jan 25 00:57:39 hey guys Jan 25 00:58:50 so down to the point. working on a project want to use gstreamer. any suggestion as to how to begin? Jan 25 00:59:27 hey guys quick question Jan 25 00:59:49 is there any way to use python without using the adafruit library ? Jan 25 01:00:31 ? Jan 25 01:03:54 thats the way i obtained it :-/ Jan 25 01:08:05 I've not had much luck with gstreamer even running except for the time I tried a full angstom build that had it included Jan 25 01:09:29 for the moment im using a version of mjpeg streamer and ti works well but there is a 2 second delay Jan 25 01:09:50 gstreamer was suggested but no luck in getting it to work :( Jan 25 01:10:20 if you can decrease the cache size try that Jan 25 01:12:14 thanks.. Jan 25 01:13:43 how is gstreamer not working? Jan 25 01:21:19 its not that it doesnt work. i jsut dont know how to use it or rather the commands to actually use gstreamer Jan 25 01:33:08 what are you trying to do? Jan 25 01:34:12 can i use python to do blink an led without using the adafruit lib ? Jan 25 01:35:28 can YOU? Jan 25 01:35:36 m asking Jan 25 01:35:47 is it possible ? Jan 25 01:36:11 well adafruit gives you a full tutorial on how to use it... Jan 25 01:36:44 without using adafruit lib Jan 25 01:38:48 anyone else has experience with gstreamer? Jan 25 01:39:45 what are you trying to do with it? Jan 25 01:39:55 are you trying to conjure up pots of gold? Jan 25 01:40:12 lol just obtain video from a webcam Jan 25 01:40:22 what kind of webcam is it? Jan 25 01:40:35 Acme Non Functional Dummy useless cam? Jan 25 01:40:58 its a logitech c270 Jan 25 01:41:12 I can think of seeing at least 2-3 tutorials on the web Jan 25 01:41:23 have you consider searching this thing called the web? Jan 25 01:41:56 ive been searching to no avail Jan 25 01:43:13 if you know of any tutorials out there i would LOVE to know about them. Jan 25 01:43:21 sharing is caring and all that Jan 25 02:22:11 I don't have time to search for other folks and I don't recall the website Jan 25 02:22:26 however, I vaguely recall it was done by a ham (I think) Jan 25 02:30:36 lol Jan 25 02:32:03 i can tell this is "your thing" Jan 25 02:32:36 what keywords are you using to search? Jan 25 02:32:57 if you asked me a few months ago, I might be able to just paste it but since my gst project is done, I am purging old info Jan 25 02:35:05 if D14 blinks once and D5 is on... what can be wrong? Jan 25 02:35:40 also, DC 5V input turns on D13 Jan 25 02:36:10 (on BB-xM) Jan 25 02:36:46 serial output shows "60" Jan 25 02:37:43 that most likely means your card is not set up properly Jan 25 02:38:27 the 60 part is showing that your CPU is powering up Jan 25 02:38:28 actually, it did boot once somehow with USB cable... but now it's corrupt again? **** ENDING LOGGING AT Sat Jan 25 02:59:59 2014
