**** BEGIN LOGGING AT Wed Feb 10 02:59:59 2016 Feb 10 03:27:30 Hi guys, i'm having a terrible time when trying to output a PWM, I've tried using 3 different images of debian, and all images give me the same error: Feb 10 03:27:32 error: error updating PWM freq and value: undefined, Error: ENOENT, no such file or directory 'undefined/duty' Feb 10 03:38:33 any help? D: Feb 10 04:32:52 uart on BBB not working Feb 10 04:32:57 someone help Feb 10 05:43:26 hey everyone, Feb 10 05:43:39 http://answers.opencv.org/question/87024/basic-opencv-operations-not-working-in-beaglebone-black/ Feb 10 05:44:13 i m having exactly the same problem mentioned in the above link.. can anyone tell me about it? Feb 10 05:44:41 http://answers.opencv.org/question/87024/basic-opencv-operations-not-working-in-beaglebone-black/ Feb 10 05:44:44 i m having exactly the same problem mentioned in the above link.. can anyone tell me about it? Feb 10 06:22:54 ?? Feb 10 06:43:40 Guest86652: this looks highly TI specific. Feb 10 07:04:02 do you have any idea that what should i od? Feb 10 07:04:04 do? Feb 10 07:06:24 Guest86652: add information wat OS you are using and where you got opencv from Feb 10 07:41:11 is there some systemd service/target other than udev that is required for drivers to be loaded when a usb device is plugged in? Feb 10 07:48:40 i m using linux Feb 10 07:49:11 https://www.cs.sfu.ca/CourseCentral/433/bfraser/other/2014-student-howtos/OpenCVonBBB.pdf Feb 10 07:49:22 and have installed opencv from link link Feb 10 07:50:25 "linux ubuntu" Feb 10 08:03:56 that has conflicting information. once it says ubuntu and then it says debian Feb 10 08:04:09 I guess you should talk to whoever wrote that guide and maintains it Feb 10 08:19:00 yates: no Feb 10 08:44:21 hello Feb 10 08:54:03 a Question from my husband for Bebeaglebone X15: does anyone know, which value the the ACTLR register is (linux)? Feb 10 08:54:13 I am an owl again... Feb 10 08:55:42 Sandhya_: that's the auxiliary control register right? Feb 10 08:55:49 yes Feb 10 08:57:45 maybe check the u-boot sources, since if it's being changed then that's the most likely place it would be done (by smc call) Feb 10 08:59:31 ok, I'll tell them Feb 10 08:59:35 (apart from the SMP bit which also needs to be set/cleared if power management is done, but that can be done by direct write rather than smc call) Feb 10 09:00:52 or you could ask on the forum for someone to check the value using a debugger Feb 10 12:29:16 help Feb 10 15:51:45 zmatt: you home? Feb 10 15:53:47 i've using a telit le910 cellular modem on my board. my code begins by powering on the le910 and then expecting to be able to run qmicli commands to start the network. Feb 10 15:55:15 that is, normally, powering on the le910 results in a) the le910 enumerating on the usb bus (as seen via lsusb), and b) the qmi driver loaded, as seen via the presence of /dev/cdc-wdm0 Feb 10 15:55:48 my board also has a standard eth0 wired network interface Feb 10 15:56:20 i can observe system log messages via the uart0 serial port Feb 10 15:56:43 i've also created a systemd service file for my code, timed.service Feb 10 15:57:03 i've run "systemctl enable timed", so that it starts on boot Feb 10 15:57:23 if i boot with the eth0 cable in, it works fine Feb 10 15:57:49 if i boot with the eth0 cable disconnected, the qmi driver is not getting loaded Feb 10 15:59:06 when it works, i see messages on the log that qmi is loaded. when it doesn't, i don't. Feb 10 15:59:31 so what difference can having eth0 unplugged make? Feb 10 16:01:04 it looks as if udev is not properly loading the qmi driver in response to "plugging in" the le910. Feb 10 16:01:34 i see this on the log when eth0 is unplugged: 90.293338] usb 1-1: new high-speed USB device number 2 using musb-hdrc Feb 10 16:01:55 which says the kernel is getting notified that the le910 has been "plugged in" Feb 10 16:03:50 but i don't see the rest of what i normally see after that Feb 10 16:07:44 ? Feb 10 16:32:16 dead today, man Feb 10 16:56:32 i have a debian jessie/4.4 system that behaves differently in response to a usb device being plugged in depending on whether or not the eth0 wired network interface is plugged in: http://ur1.ca/oi4el -> http://paste.fedoraproject.org/320843/14551232 Feb 10 16:58:02 any thoughts on why these two scenarios would cause a difference in usb device processing? Feb 10 17:00:51 which component emits the message "[ 40.320030] usb 1-1: New USB device found, idVendor=1bc7, idProduct=1201"? Feb 10 17:26:47 yates: Going out on a limb here,but that's probably either the kernel or udev that's printing that message Feb 10 17:27:53 someone else (in #systemd) said it was the kernel Feb 10 17:30:27 does dmesg only report from the beginning of the current boot? Feb 10 17:34:10 dmesg, yes, var/log/messages nope .. dmesg probably relates to proc somewhere Feb 10 17:34:25 might be a var/log/dmesg .. debian is strange Feb 10 17:35:19 there is a /var/log/kern.log Feb 10 17:35:23 that looks like the one Feb 10 17:45:14 hello. is there a way to stop the infernal blinking on the beagle bone black? i have the debian install Feb 10 17:45:31 it's blinking like crazy, constantly... everything works though Feb 10 17:45:41 in a dark room, it's like a strobe light Feb 10 17:52:19 talin_: echo none > /sys/class/leds/beaglebone:green:usr0/trigge Feb 10 17:52:24 talin_: echo none > /sys/class/leds/beaglebone:green:usr0/trigger Feb 10 17:52:31 similarly for usr1, 2, and 3 Feb 10 17:56:14 zmatt: you up? Feb 10 17:57:19 any bbb/kernel dudes here? Feb 10 18:12:37 hey anybody know the most powerful radio-free dev board system out there? Feb 10 18:13:57 Any takers? Feb 10 18:41:17 radio-free? Feb 10 18:42:02 yates: huh, i can't edit that file, even when i have access to write in it Feb 10 18:42:08 yates: i guess it is locked somehow Feb 10 19:03:17 talin_: as root? Feb 10 19:03:44 it's a directory Feb 10 19:05:50 yates: it worked now. i tried with sudo, but apparently that wouldn't work Feb 10 19:06:02 yates: thanks a lot Feb 10 19:06:09 good. np. have fun! Feb 10 21:29:10 Hello World Feb 10 21:46:51 hey folks, i posted our on-going problem getting our le910 to enumerate when the eth0 is plugged in on the e2e forum: https://e2e.ti.com/support/embedded/linux/f/354/t/489649 Feb 10 21:47:28 if anyone has any thoughts, i'd appreciate hearing them, either here or on the e2e forum. Feb 10 21:47:56 correction: the problem is getting the le910 to enumerate when the eth0 is NOT plugged in. Feb 10 22:06:17 So you have a cell phone LTE module that isn't recognized unless the ethernet cable is plugged? Feb 11 00:07:39 Hi all, I'm looking at transitioning a raspberry pi project to beaglebone, mostly because of the beaglebone serial cape - we need RS-485 and CAN bus. Are GPIO pins still available with a cape installed? We need about 5-6 GPIO Feb 11 00:18:47 what do you mean by available? Feb 11 00:18:54 physically? electrically? or ? Feb 11 00:22:04 I only know about arduino shields - I know they take over some portion of the available GPIO's. I guess it's the same thing but I didn't see much detail on "what's left" after using that cape. But also physically, yes, since it seems the capes all cover the entirety of the two connectors Feb 11 00:23:41 ah I just found https://docs.google.com/document/d/1sgurQ-7gLyn7g-Kg983NRM0aDkYEqHqy9dmrieX_RUM/edit which I think answers part of my question, but is there a standard way to deal with accessing other pins when using a cape? In terms of the physical connections? Feb 11 00:27:11 well, physically, the connectors may be covered up but the GPIOs are available. Feb 11 00:27:31 you can add an interposer expansion board to pull out the GPIOs you need. They are available Feb 11 00:27:59 GenTooMan: hilarious, isn't it? Feb 11 00:31:39 hey folks, i posted our on-going problem getting our le910 to enumerate when the eth0 is not plugged in on the e2e forum: https://e2e.ti.com/support/embedded/linux/f/354/t/489649 Feb 11 00:31:47 if anyone has any thoughts, i'd appreciate hearing them, either here or on the e2e forum. Feb 11 00:36:24 back in a reboot Feb 11 00:49:50 ds2: thanks! Feb 11 01:30:18 sorry i was away. did anyone respond to my query on the e2e post? Feb 11 01:31:13 what is rcn's email address? zmatt, you said he didn't mind folks emailing him, right? Feb 11 01:33:01 HI Feb 11 01:33:36 I LOOK FOR Element 14 BeagleBone Black Rev C (4G) Single Board Computer Development Board Feb 11 01:36:23 it is also available from digikey last i checked Feb 11 01:47:55 yates: RN's mail is on his eewiki site Feb 11 01:48:09 and/or his github iirc Feb 11 01:49:44 ok, thanks veremit Feb 11 01:50:14 whilst its not heavily publicised .. I have used it in the past myself Feb 11 01:50:37 like here, he is most helpful Feb 11 01:51:32 OSAMAABULNAGA: https://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwjQzM_GzO7KAhWhCJoKHeD9DN8QFggtMAA&url=https%3A%2F%2Fwww.element14.com%2Fcommunity%2Fcommunity%2Fdesigncenter%2Fsingle-board-computers%2Fnext-gen_beaglebone&usg=AFQjCNE7ZAZDx7XnBEHLp-xs1A3Z0XsEow&sig2=6KuOxhJzMZVnDCSk_4TCCg Feb 11 01:51:48 https://www.element14.com/community/community/designcenter/single-board-computers/next-gen_beaglebone damnit Feb 11 01:52:28 apologies for noise Feb 11 02:02:39 ok, more info on my issue: it seems to definitely be related to the usb "babble" interrupt: see more information on the e2e post: https://e2e.ti.com/support/embedded/linux/f/354/p/489649/1767594#1767594 Feb 11 02:03:10 yay! the babble .. hahahaha... yes I remember that .. Feb 11 02:03:17 veremit: can you email me his address? i can't find it. yates@ieee.org Feb 11 02:03:19 please? Feb 11 02:03:27 really? Feb 11 02:03:29 I can't promise I'll find it .. Feb 11 02:03:35 it was some years ago now Feb 11 02:03:42 on death of firstborn... Feb 11 02:04:08 hey, find the solution - that would be even better! Feb 11 02:04:18 give up on usb :D Feb 11 02:04:20 if you can remember. Feb 11 02:04:24 oh sorry .. lol Feb 11 02:04:24 doh!!!! Feb 11 02:04:45 that's kinda late - board is built, demo is scheduled.... Feb 11 02:04:58 here's a MASSIVE HINT : https://github.com/RobertCNelson Feb 11 02:05:19 where? i don't see it? :) Feb 11 02:05:24 thanks, man! Feb 11 02:05:37 I suggest you get your eyes tested ;) Feb 11 02:05:38 lol Feb 11 02:06:04 I got it in a quarter of a second Feb 11 02:31:37 Hi guys, is there anyone that could help with PWM output? :) Feb 11 02:33:44 I run the following JS: Feb 11 02:33:45 var b = require('bonescript'); b.analogWrite('P8_34',0.7,200.0,console.log); Feb 11 02:33:57 and I get the following error code: Feb 11 02:34:13 error: error updating PWM freq and value: undefined, Error: ENOENT, no such file or directory 'undefined/duty' Feb 11 02:35:52 I've installed countless images, run updates, upgrades, and re-installed tonnes of modules, but the error persists. Feb 11 02:47:40 then the error is in your code :) Feb 11 02:57:35 How though? that is literally the default code listed on the info page for analogWrite on the the beaglebone101 webpage **** ENDING LOGGING AT Thu Feb 11 02:59:58 2016
