**** BEGIN LOGGING AT Tue Oct 21 02:59:59 2014 Oct 21 07:19:34 hi Oct 21 07:21:18 i would like to know, if there is the Oct 21 07:21:26 yes, there is the Oct 21 07:25:59 possibility to connect a 7 inches lcd to the bb and the management of sound, a keyboard, mouse, or to assembly it with a look similar a mobile phone Oct 21 07:26:35 you mean, you want to run android? Oct 21 07:27:40 awaiting for your reply, greetings pavlx iw0fzw Oct 21 07:28:31 hmm.. paolo del bene... Oct 21 07:28:34 nice name Oct 21 07:28:59 pavlx: yes, there is the possibility. no you dont want to use the bbb instead, but buy a cheap phone Oct 21 07:29:52 no, GNU/linux, because i don't want become crazy to build packages for Android Oct 21 07:30:04 still get a cheap phone Oct 21 07:31:49 i got a mb, but it works with Android, which is a NON free operating system Oct 21 07:32:09 get one that supports ubuntu Oct 21 07:32:34 pavlx: and the bbb need proprietary sgx drivers if you want it to be shiny, which are also non-free, and a royal PITA Oct 21 07:32:53 pavlx: so if you claim you want something *FREE*, you should maybe better do your recherche homework first Oct 21 07:32:56 I've honestly never gotten the sgx drivers working Oct 21 07:32:59 and I have REALLY TRIED Oct 21 07:34:49 instead i need GNU/linux because for Android there is a free software like: echolinux, qtel, svxlink. .. Oct 21 07:38:44 for Android there are not free softwares like those, there is only echolink Oct 21 07:40:36 and the author force people to accept and send back of the license signed y Oct 21 07:42:12 signed up, and it authorize to the use only of one copy Oct 21 07:43:05 that is a NDA Not Disclosure Agreement Oct 21 07:44:23 if yoy accept you can use echolink or you must delete it Oct 21 07:44:24 pavlx: so besides all that buzzwording and complaining, what do you want us to tell you now? Oct 21 07:45:42 i need a device which can use a lcd Oct 21 07:45:45 pavlx: you can run a pretty-much standard linux on the BBB, but will *not* give that shiny phone gui out of the box Oct 21 07:46:40 pavlx: grab a wandboard, add an hdmi monitor, enjoy free graphics drivers. Oct 21 07:48:02 then you can run a bling-bling qt5 application with that warm, fuzzy, free feeling in your belly Oct 21 07:49:06 obviously you don't know me, pretty does not interest me Oct 21 07:49:48 yeah. sorry for not knowing you. Oct 21 07:49:58 honestly, what did you expect here? Oct 21 07:50:17 I got nothing. Oct 21 07:50:27 honestly: hrhr. sry. Oct 21 07:50:39 i need something little dimensions that next year i Oct 21 07:50:52 pavlx: you sound like: "please tell me the BBB is a super free gnu/linux phone-style replacement" Oct 21 07:51:05 and sorry no, it is not going to be that. Oct 21 07:51:30 can use everywhere Oct 21 07:51:34 yes, you can glue an lcd to it. no, it will not work within 5 minutes. Oct 21 07:53:32 i don't need an external screen Oct 21 07:53:46 and no, the bbb doesn't come with supprt for being battery powered, nor does it have enough performance for being a desktop/laptop replacement Oct 21 07:54:12 pavlx: strange. the external lcd was your initial question. Oct 21 07:54:13 09:25 < pavlx> possibility to connect a 7 inches lcd to the bb Oct 21 07:54:17 Oct 21 07:56:01 and infact i don't need of an external screen like a monitor Oct 21 07:57:12 but something which can use a 7 inches lcd Oct 21 07:57:52 so if the lcd is not meant to be used as a monitor, what would it its purpose then? Oct 21 07:57:57 svxlink is a replacement of VoIP Oct 21 07:58:18 sure, you can use it as a mounting plate.... Oct 21 07:59:09 it was thinked to connect hamradio stations in the world Oct 21 07:59:19 yay for more buzzwords! Oct 21 07:59:57 pavlx: googling for svxlink gives me a lot of entries of people running it on a raspi. so why not go for one? Oct 21 08:02:05 wasn't svxlink that open source echolink clone? Oct 21 08:03:39 you need to active frequency, shift, and tones and people listen your communication in any part of the world, because that software works for radio not mobile phones Oct 21 08:04:16 echolink is the original one Oct 21 08:06:08 then were developed those which are free software GNU General Public License Oct 21 08:08:23 i saw the raspy and many say that bb is better than any other one Oct 21 08:09:31 i think that the competitor could be Arduino Oct 21 08:10:16 or the italian Fox of acme systems Oct 21 08:10:23 pavlx: i dont know where you come from, but people around here frown upon people who use GNU in each sentence Oct 21 08:10:33 pavlx: it sounds like a religion Oct 21 08:12:48 i heared these words, but different years ago. Oct 21 08:12:49 pavlx: or to put it differently: people have a pragmatist bias: they use whatever works for them. they dont care whether it's RMS approved or not Oct 21 08:13:39 when those fb, linkedu Oct 21 08:14:59 linkedin, myspace, youtube don't exist again Oct 21 08:15:37 sorry, you are speaking incoherently. could you rephrase this sentence please? Oct 21 08:15:49 years passed but stupidity remains Oct 21 08:15:59 film at 11 Oct 21 08:17:19 we can see what happened less than 2 years ago when all the world was spied by NSA Oct 21 08:19:16 to Aemendament 5 of American Constitution NSA was not authorized to asks data Oct 21 08:19:45 * LetoThe2nd puts on tin foil hat and gets popcorn Oct 21 08:21:49 11 September 2001 ? watch http://luogocomune.net Oct 21 08:22:46 the war was in the mind of George Bush Oct 21 08:23:03 pavlx: ok, please stop it now. Oct 21 08:23:24 pavlx: this is a technical channel. no consiracy theories are wnated or accepted here. please stay on topic Oct 21 08:24:18 who can run for hours in the airspace without authorization of NORAD ? Oct 21 08:24:36 pavlx: *last* *warning* Oct 21 08:26:07 no one can do it or airforce destroy in the air the airplane if not reply to radio communications Oct 21 08:30:47 natsukao: treat carefully, or you'll be gone for good Oct 21 08:45:45 hi ... for beagle bone black which one is a correct defconfig file in 3.8.13 kerenel Oct 21 08:48:07 am335x_evm_defconfig or beaglebone_defconfig or any thing else ... please help me Oct 21 08:49:58 the am335x_evm is a totaly different board Oct 21 08:50:10 the rest... dunno... what did google say? Oct 21 08:54:47 i tryed with beaglebone_defconfig but it is throughing erroer like Unhandled fault: external abort on non-linefetch (0x1028) at 0xf9e3e044 Internal error: : 1028 [#1] SMP THUMB2 Oct 21 08:55:12 Guest31175: by 3.8.13 I'm guessing this is a TI based kernel, so it's going to be something BBB specific, look at what distros like RCNs debian or angstrom use as defconfig Oct 21 08:55:13 what gives that error? Oct 21 08:55:15 your compiler? Oct 21 08:56:38 my compiler is arm-linux-gnueabi Oct 21 08:57:30 or i need to modified config file Oct 21 08:57:40 sorry .config file Oct 21 08:59:41 Or any specific kernel version which i can use here Oct 21 08:59:57 what are you trying to do? Oct 21 09:00:28 what have you done sofar and where did you get stuck? Oct 21 09:03:14 i want to install my own build kernel !!! so first i build a MLO and u-boot.img after that i am bulding kernel . i have created partion on SD card . Oct 21 09:05:06 download kernel form ---------- git clone git://github.com/beagleboard/kernel.git Oct 21 09:05:46 what distro do you use? Oct 21 09:06:09 the easiest way is to use the build environment your distro uses and just supply it with the kernel version you want to have Oct 21 09:06:15 that usually works Oct 21 09:07:21 and follow same step which given in link -------- http://elinux.org/Building_BBB_Kernel Oct 21 09:09:02 sorry you mean to say distro Oct 21 09:11:55 hear i am using ubuntu 12.04 and my cross comipler is arm-linux-gnueabi-gcc Oct 21 09:13:32 i meant the embedded distro Oct 21 09:14:34 or in other words: which distro is installed on the BBB? Oct 21 09:17:06 IN BBB by default installed 3.8 kernel Oct 21 09:17:26 VFS: Cannot open root device "mmcblk0p2" or unknown-block(0,0): error -6 Please append a correct "root=" boot option; here are the available partitions: Oct 21 09:18:24 in this error why it is not able to detect mmcblk0p2 Oct 21 09:19:40 most likely driver missing or wrong setup of initramfs Oct 21 09:20:20 Guest31175: which userland are you using? what is on your root partition on the BBB? Oct 21 09:20:26 KotH lol why initramfs in embedded stuff? Oct 21 09:20:53 koth to make the bootprozess slower? Oct 21 09:21:16 woglinde: people do weird shit Oct 21 09:21:28 could you suggest which driver is required for this Oct 21 09:22:53 woglinde: btw: for a do-not-change-rootfs thing, running everything out of initramfs is the right thing to do Oct 21 09:23:11 woglinde: and quite fast too, as you can load it compressed Oct 21 09:23:36 koth ah yes update Oct 21 09:23:36 woglinde: did that a while ago in a system that couldnt access its spi boot rom after kernel loading Oct 21 09:23:46 or resucue Oct 21 09:23:50 rescue even Oct 21 09:23:52 yes yes Oct 21 09:30:34 Is it safe to use the Beagleboard Black both as a client and a host to the same self-powered USB hub? (With two seperate cables). I was thinking, this way, I only have to use one power cable for my setup. (I don't want to just try, I'm thinking the problem might be an electrical one and then I might fry my equipment). I will also have an USB hard drive and a wifi adapter plugged into the USB hub. schematics here: http://imgbox.com/cVwmFZcD Oct 21 09:31:33 should work fine Oct 21 09:32:28 though i wonder why you want to use the host and client port at the same time and connect them together Oct 21 09:34:16 i want to access the devices i plugged in to the hub from the beagleboard. but i need (?) to plug the board itself into the hub as well in order to power it from the usb hub's power supply Oct 21 09:35:39 i found the beagle board i need Oct 21 09:37:43 will be a pleeasure to have a 7 inches lcd + 2 rs 232 + 2 rs 485 + mic + output audio + 1 can bus ... Oct 21 10:01:35 and now i go to sleep Oct 21 10:09:03 KotH: are you like, really sure? :) also, if you want, please have a look at my schematics image, if you didn't really understand exacly how I'm going to connect everything Oct 21 10:09:22 rasputinkonstant: i did Oct 21 10:09:28 rasputinkonstant: i did have a look Oct 21 10:09:41 rasputinkonstant: otherwise i wouldnt have said it's ok Oct 21 10:10:03 ok, thank you Oct 21 10:10:16 rasputinkonstant: basically, you have a single power source (the hub), thus everything is on the same voltage level Oct 21 10:11:21 oh yes, i'm a sucker for that kind of answer. i'll try and plug in the power then Oct 21 12:40:56 hi guys ! Oct 21 12:41:37 I would like to communicate with a temperature sensor via the I²C on the BBB Oct 21 12:42:22 however, it seems that the only I²C bus I can access is the i2c - 0 Oct 21 12:42:39 on which the alimentation is, if I'm not mistaken Oct 21 12:43:53 I'd like to use the I²C - 2, but it doesn't look like it's recognize by the OS (I'm using the Sitara developpment kit furnished by TI) Oct 21 12:44:28 <_av500_> for sitara devkits, please talk to TI Oct 21 12:45:27 I'm quite unsure it has anything to do with TI actually Oct 21 12:45:59 when I try and execute the "i2cdetect -l" command, the only output I get is "i2c-0 i2c OMAP I2C adapter I2C adapter" Oct 21 12:46:18 <_av500_> yes Oct 21 12:46:42 <_av500_> now repeat that with Debian for BBB Oct 21 12:48:54 you think the TI SDK could somehow "fuck up" the I²C buses ? Oct 21 12:49:27 nobody uses the TI SDK here Oct 21 12:49:38 <_av500_> thing is, I know nothing about the TI SDK Oct 21 12:49:45 <_av500_> zero Oct 21 12:49:50 <_av500_> but people here use debian Oct 21 12:50:01 <_av500_> so if you want help, try to use the thing that others use too Oct 21 12:50:12 <_av500_> because then they can relate Oct 21 12:50:13 TI SDK is probably still on some obscure "done" kernel Oct 21 12:51:08 alright Oct 21 13:13:33 dear all - what is 0x24 on i2c0 ? Oct 21 13:14:34 <_av500_> the pmic? Oct 21 13:17:00 checking it - ty... Oct 21 13:31:35 Hello and thank you in advance. I currently have an LCD4 cape and the ADC cape made by Circuitco. After exploring the internet for a while I discovered that there is a conflict between the two capes at pin 21, although the LCD doesn't seem to even use this pin. I know how to edit the overlay and remove the block/mux code from the LCD overlay but I don't know how to compile the new kernel with the changes and install it on the SD c Oct 21 13:37:40 did anyone here used the ADC to measure current? Oct 21 13:37:41 Hi, Beagle ADC AIN pins can handle 0 to 1,8V with 12bit accuracy (4096 bits), so 4096bits/1800mV=2.275 steps per mV. If I want to know the actual voltage in mV at AIN pin I have to divide its digital reading by 2.275 Oct 21 13:38:03 Am I right ? Can you confirm it ? Oct 21 13:40:15 Freddy: Yeah, that is pretty typical of ADC readings. Oct 21 13:40:49 cityoflights2: Certainly possible if you use two hannels and measure the drop across a shunt. Oct 21 13:44:53 agmlego: It's a formula I found logically myself, but never seen on any documentation, so I am not sure, that's why I'm asking for... Oct 21 13:49:05 Freddy: It is a simple enough formula that most people derive it themselves and use it. Oct 21 14:15:55 _av500_: that's pmic Oct 21 14:18:29 what's the purpose of 'i2c mw 0x24 1 0x3e' during boot? looks like it is 3e by default ? talking about bbb Oct 21 14:21:10 0011 1110 - AC sink enable, USB sink enable, AC power on, USB power on, max ac 2.5 A, max usb 1.3 a Oct 21 16:00:30 Are there any plans to do GSoC for 2015? Oct 21 16:02:34 <_av500_> afurbee: yes Oct 21 16:02:41 <_av500_> we will apply Oct 21 16:03:01 <_av500_> maquefel: it is setting the max usb current drawn Oct 21 16:03:25 <_av500_> it might be that uboot sets a lower value Oct 21 16:03:35 <_av500_> ah that is uboot Oct 21 16:56:38 _av500_: ty - you mean common uboot am335x has different defaults? Oct 21 16:59:49 KotH, Hi was it you who said that to read PWM I should use some kind of comparator units ? Oct 21 17:03:08 anyone can answer my question ? how to read pwm signal on BB? Oct 21 17:12:42 what are 34 50 70 on i2c0 bus? Oct 21 17:13:07 or Oct 21 17:13:25 where i can fin list of devices on i2c0 bus for bbb ? Oct 21 17:13:41 tried the SRM? Oct 21 17:13:45 one is power, others are hdmi and eeprom Oct 21 17:14:27 Humpelstilzchen: well on SRM i haven't found the address of power :\ Oct 21 17:14:59 maquefel: but it should have the device name Oct 21 17:15:02 Humpelstilzchen: only schematics that eeprom, power and hdmi are ob bus Oct 21 17:15:51 if you know the vendor and product you should be able to look them up. Or you could try the devicetree Oct 21 17:18:03 Humpelstilzchen: i am truing from uboot Oct 21 17:18:27 Humpelstilzchen: i2c md givving me nothing Oct 21 17:19:13 i am able to cominicate with power on 0x24, but not able to read others Oct 21 17:36:11 can i access eeprom from uboot? Oct 21 19:01:25 mkad: yes it was me Oct 21 19:03:15 mkad: see section 20 "Timers" in the TRM Oct 21 19:03:25 mkad: no idea how these are interfaced in linux Oct 21 19:04:04 KotH, ok so you dont know if theyre available in BBB Oct 21 19:04:53 mkad: they are available (the hardware is there) Oct 21 19:05:08 mkad: i dont know how the software part looks like Oct 21 19:05:16 mkad: i've never used capture/compare units in linux Oct 21 19:11:01 ok no clue Oct 21 19:11:30 Hi, I need to connect xbee to beaglebone black and management through NodeJS? Tell me please how to do it better yeah where this can be read in detail. Thank! Oct 21 19:16:33 KotH, ok kernel is switching context and is not realtime so there is no chance of reliable user space high speed sampling I guess PRU can only do that Oct 21 19:17:18 mkad: err.. what? Oct 21 19:17:40 mkad: the point of a capture compare unit is exactly that it does this stuff in _hardware_ Oct 21 19:18:01 mkad: it doesnt matter how long the software part takes, the hardware already measured the pulse length Oct 21 19:18:10 mkad: as i said, read the TRM Oct 21 19:18:41 witem: step one: do not use node.js Oct 21 19:18:41 TRM is Europe's largest manufacturer and distributor of Nutritional Feeds Supplements Oct 21 19:19:13 witem: step two: explain what you did and what you struggle with Oct 21 19:19:21 mkad: technical reference manual Oct 21 19:20:00 witem: also, see topic about node.js Oct 21 19:22:55 KotH: need to use Node.js Oct 21 19:23:51 witem: see topic then Oct 21 20:07:29 has anyone had recent luck getting debian installed via RobertCNelson's netinstall method? Oct 21 20:11:20 how do i get the my bbb using the ubuntu 12.04.4 image from http://www.armhf.com/boards/beaglebone-black/bbb-sd-install/ do networking via usb like the default angstrom image does? i tried changing /etc/network/interfaces to https://www.refheap.com/91983 and that isn't enough Oct 21 20:11:34 do i have to do some udev rules on my laptop? Oct 21 20:12:02 ozzloy, why shitbuntu? Oct 21 20:12:56 ozzloy, I read on some mailing list that not everything there is working... besides that it's not test/supported.. but I am not an expert Oct 21 20:13:45 mkad, because i want to run ROS Oct 21 20:15:08 mkad, http://www.armhf.com/boards/beaglebone-black/ says its aim "is to provide ... images that are very stable" Oct 21 20:15:31 i'm totally down to switching to something else though Oct 21 20:15:48 i don't think this current issue is really an ubuntu specific thing Oct 21 20:21:57 interesting, when i boot the bbb from the ubuntu sd, lsusb on my laptop shows no new device Oct 21 20:25:08 what do i have to configure to make the bbb be a usb device when plugged into my laptop? Oct 21 20:25:15 ozzloy, it seems that it can be installed on Debian as well Oct 21 20:25:39 ozzloy, or even rebuild with apt-get source Oct 21 20:25:41 mkad, ROS? yeah, it _can_ be installed on several distros, but ubuntu is the most supported Oct 21 20:25:52 ah I see Oct 21 20:26:25 some friends tried ROS on (something other than ubuntu) and eventually gave up Oct 21 20:26:40 i've been having a fine time with ubuntu ROS Oct 21 20:27:01 mkad, do you think switching to debian would fix the problem i'm currently trying to fix? Oct 21 20:27:03 so what is the license of that soft? Oct 21 20:27:36 ozzloy, I dont know I use Debian and I can use internet over usb Oct 21 20:28:07 ROS? i think it's bsd? Oct 21 20:28:32 what? Oct 21 20:28:36 ah license Oct 21 20:28:53 ok so your problem is that you want internet over usb right? Oct 21 20:29:03 yeah Oct 21 20:29:58 can u ssh on bbb ? Oct 21 20:30:03 and ideally i'd keep ubuntu since my group of friends are trying to standardize the platform Oct 21 20:30:26 i can ssh via usb when it's booted with the default onboard image Oct 21 20:30:45 i can also modify the rootfs of the ubuntu image Oct 21 20:30:58 so if all i have to do is modify some files, i'm set Oct 21 20:31:05 oh you need to be able to ssh in with ubuntu Oct 21 20:31:21 and i'm fairly certain all i have to do is modify some files on the ubuntu image Oct 21 20:31:23 yes Oct 21 20:31:42 it's not a question of installing openssh-server though Oct 21 20:32:03 ok Oct 21 20:32:04 because the bbb doesn't even show up on my laptop Oct 21 20:32:19 when booting the ubuntu sd card Oct 21 20:32:28 what ifconfig shows on laptop ? Oct 21 20:32:58 should have eth? interface with address 192.168.7.1 after connecting BBB Oct 21 20:34:06 https://www.refheap.com/92118 ifconfig with bbb booting off onboard image Oct 21 20:34:23 eth2 is the bbb Oct 21 20:35:01 but when i boot off ubuntu sd, that doesn't show up. and even lsusb doesn't show anything Oct 21 20:35:09 well, doesn't show the bbb Oct 21 20:35:37 is it even booting? Oct 21 20:35:58 yes, it's blinking the heartbeat pattern Oct 21 20:36:45 https://www.refheap.com/92119 lsusb outputs Oct 21 20:37:12 ok so there is no /dev/tty... device ?/ Oct 21 20:38:46 ozzloy, do you have 3.3V usb serial adapter ? Oct 21 20:39:04 on my laptop there's /dev/tty{0-63} Oct 21 20:39:12 mkad, i do not Oct 21 20:39:26 mkad, have a 3.3v usb serial adapter Oct 21 20:40:14 not or do? Oct 21 20:40:32 mkad, i do not have a 3.3v usb serial adapter Oct 21 20:43:13 so no way of seeing what boots up ? Oct 21 20:43:23 even connecting hdmi ? Oct 21 20:43:39 mkad, i connected to hdmi and saw a login screen Oct 21 20:43:51 so i know it's booting Oct 21 20:43:56 ok so you can login Oct 21 20:44:02 keyboard? Oct 21 20:44:04 idk, didn't try Oct 21 20:44:21 lmao connect keyboard and log in to see what happens;) Oct 21 20:44:27 why? Oct 21 20:44:44 because its not brining up network for some reason Oct 21 20:44:47 maybe you can fix it Oct 21 20:45:10 at least you would see why Oct 21 20:46:42 brb, cable hunting Oct 21 20:46:49 i'm still not sure how this is going to help Oct 21 20:47:08 ozzloy, you complain about ubuntu not brining up network Oct 21 20:47:13 oh, thanks btw Oct 21 20:47:18 for helping Oct 21 20:47:40 ozzloy, if you log into it you will see log files what happens, maybe you can bring interface up manually Oct 21 20:48:21 oh yeah, maybe log files will have a clue! Oct 21 20:48:23 durp Oct 21 20:48:32 <-- silly Oct 21 20:49:30 ozzloy, you can bring interface manually by ifup eth0 Oct 21 20:52:06 wouldn't it be usb0? Oct 21 20:52:41 could be Oct 21 20:53:36 https://www.refheap.com/92120 ifconfig on the bbb booted via eMMC angstrom Oct 21 20:54:33 yeah it can be ifup usb0 Oct 21 20:54:59 just log in and check good luck:) Oct 21 20:57:41 have you tried ssh to 192.168.7.2? Oct 21 21:03:20 thurgood, no interface is up Oct 21 21:03:22 ok, so i can't actually type Oct 21 21:03:33 usb kb plugged in, nothing happens Oct 21 21:03:42 lemme try w/ angstrom image Oct 21 21:03:50 ... Oct 21 21:04:03 no interface is up where something is reporting the correct address on usb0 Oct 21 21:04:13 where? Oct 21 21:04:26 he connected hdmi tv and keyboard Oct 21 21:04:38 and was trying to log in Oct 21 21:05:45 what error message does ssh give? Oct 21 21:05:59 angstrom image doesn't even light up the usb port Oct 21 21:06:18 which board are you using? Oct 21 21:06:48 thurgood, i can ssh via usb into bbb booted from angstrom image Oct 21 21:06:54 debian is more current and better supported on the bbb afaik Oct 21 21:07:10 debian rocks! Oct 21 21:07:57 thurgood, i try the same thing when booting off http://www.armhf.com/boards/beaglebone-black/ ubuntu 12.04.4 on sd card, and the bbb doesn't even show in lsusb on my laptop Oct 21 21:08:39 so how do i make the default angstrom image turn on the usb port? Oct 21 21:09:20 oh, am i going to have to go get a 5v barrel jack power supply? Oct 21 21:09:51 wait, I thought you were in fine with anstrom Oct 21 21:10:30 angstrom image does usb networking, so until now, i didn't even try the usb port Oct 21 21:10:41 yeah, i am fine with angstrom the way it is Oct 21 21:10:41 why not use the supported images? Oct 21 21:11:12 i want to run ROS Oct 21 21:11:23 and i know the BBB can do ubuntu ROS Oct 21 21:11:26 i've seen it Oct 21 21:11:40 get BBB running first Oct 21 21:11:44 it is Oct 21 21:11:45 then worry about ROS ? Oct 21 21:11:46 :) Oct 21 21:11:51 it runs Oct 21 21:11:56 i can see a login screen Oct 21 21:12:02 it does the heartbeat Oct 21 21:12:29 but you cannot loging because keyboard is not working Oct 21 21:12:36 ... Oct 21 21:12:58 connecting a usb kb to it doesn't work. in angstrom, the usb port doesn't even light up, and in ubuntu, it lights up but typing does not work Oct 21 21:13:22 and by "lights up" i mean i have a usb cable where the housing lights up when there's power Oct 21 21:13:36 to let me know if the usb port even has power Oct 21 21:13:40 also it looks cool Oct 21 21:14:19 is usb kb supposed to work when bbb is booted via usb mini port and no other power source? Oct 21 21:14:28 I would suggest a 5v barrel, personally Oct 21 21:14:30 if it's not, then i'll go hunting for a power supply Oct 21 21:14:43 what thurgood just sai Oct 21 21:14:50 ok, i'll just go look for a power supply irregardlesserary Oct 21 21:15:00 for sure ethernet does not work without 5V barrel afaik Oct 21 21:15:11 do you have the keyboard attached when you apply power? Oct 21 21:15:30 i tried that and attaching it after it was completely booted Oct 21 21:15:36 hot-plug support isn't so hot on some kernels with the bbb Oct 21 21:16:10 thurgood, it should be at least 2A 5V power supply right? Oct 21 21:16:27 I never tried 1.5 ^^ Oct 21 21:18:29 ozzloy, before I go away, I hope you are aware that ROS is packaged for ubuntu, and ubuntu is using deb (Debian packaging system) so there is a high chance that it would install without any problems on Debian's or you could rebuild packages on your own. Oct 21 21:19:05 mkad, some friends tried exactly that and failed Oct 21 21:19:12 i'd expect to see a similar fate Oct 21 21:19:21 rebuiling ? Oct 21 21:19:39 yeah, but we're all out of our realm there Oct 21 21:19:42 not sure what the min amperage is, but usb only provides 500mA if it's in spec Oct 21 21:19:58 1.5A should be fine Oct 21 21:20:14 mkad, thanks again for the help Oct 21 21:20:40 if you're willing to walk me through the process of building stuff, i'd give it a try Oct 21 21:20:48 I think the guidelines suggest 2A supply because the board and peripherals can draw that much at absolute max. Oct 21 21:21:01 brb, power supply hunting Oct 21 21:21:04 ozzloy: How did your friends fail when installing on debian? Oct 21 21:21:21 agmlego, ROS Oct 21 21:21:37 mkad: I am aware. Oct 21 21:21:39 agmlego, he wants http://wiki.ros.org/indigo/Installation/Ubuntu Oct 21 21:21:42 yeah, but at those currents the usb power supply he's using would fail most likely long before reaching those draws Oct 21 21:21:42 ah ok Oct 21 21:21:43 mkad: I am aware. Oct 21 21:21:51 sorry then:) Oct 21 21:21:53 thurgood: Sure. Oct 21 21:22:11 ozzloy: Because the process here (http://wiki.ros.org/hydro/Installation/Debian) looks straightforward and precise. Oct 21 21:22:49 thurgood: Thoguh a *good* 2A supply will actually provide that much power. ;-P Oct 21 21:23:08 true Oct 21 21:28:05 ozzloy: is your keyboard wired btw? Oct 21 21:29:26 thurgood, yes Oct 21 21:29:50 usb Oct 21 21:30:09 just checking, because wireless sometimes require drivers that get left out occasionally Oct 21 21:31:01 brb, running to hsc (electronics junk store) to get a power supply Oct 21 21:32:11 thurgood, btw, what i was hoping to do is get the bbb booted off the ubuntu 12.04.4 image and doing networking via usb just like the default angstrom image does Oct 21 21:32:22 k, brb for real Oct 21 21:44:11 would it be possible to connect a beaglebone black to a cd drive?, if so any suggestions on how i could approch this? Oct 21 21:44:41 USB CD drive Oct 21 21:48:07 would the data transfer be quicker if it was done with the I/O pins to a sata cd drive? Oct 21 22:37:48 ok, same behavior as before even with 5v 2a power supply Oct 21 22:39:37 can someone confirm that they've run some image with a plugged in usb keyboard? Oct 21 22:39:43 on bbb Oct 21 22:40:38 i'd like to try that image on my micro sd, boot from it and see if my bbb still doesn't do usb kb Oct 21 22:41:43 never had problems with usb kb or mouse with bbb here Oct 21 22:41:58 provided plugged in before you apply power :) Oct 21 22:42:08 which image you running? Oct 21 22:42:20 3.8 vintage Oct 21 22:42:26 link? Oct 21 22:42:30 no wait .. possibly a 3.10 or 3.11 Oct 21 22:42:51 this was last year .. lol .. dunno whatever RN had up on his site... Oct 21 22:43:24 idk who RN is Oct 21 22:43:31 robot ninja? Oct 21 22:44:15 veremit, what about the default image that ships on the eMMC of the bbb? Oct 21 22:44:30 do you know if that worked with usb kb for you? Oct 21 22:44:46 https://eewiki.net/display/linuxonarm/BeagleBone+Black Oct 21 22:45:08 if it don't work.. you got a faulty beagle or keyboard Oct 21 22:45:24 but hotplug used to be intermittent on bbb Oct 21 22:45:26 kb is typing this right now Oct 21 22:45:35 while plugged into my laptop Oct 21 22:45:48 i had the kb plugged in during boot Oct 21 22:45:51 before power on Oct 21 22:46:08 should be fine Oct 21 22:46:31 I had a usb hub plugged in Oct 21 22:47:24 this is infuriating Oct 21 22:47:32 i can see the login prompt on the ubuntu image, and i can see the desktop for the angstrom image Oct 21 22:48:14 what about the images here: http://beagleboard.org/latest-images Oct 21 22:51:13 no idea .. haven't altered mine for about 8-10months now .. its running my caching dns and a usb hdd samba share Oct 21 22:53:29 that sounds really great right about now Oct 21 22:57:26 agmlego, idk, i wasn't there when they tried it. i just dl'd the debian image. gonna try it out. if it works i'll start trying that guide Oct 21 22:57:45 agmlego, i didn't notice your message until just now Oct 21 22:58:05 I see. Oct 21 23:59:31 hello Oct 22 00:00:30 anyone with experience with ubuntu on beaglebone black Oct 22 00:01:17 Guest85775: I'm sure several people have such experience. best to ask your question and wait around for someone to notice it than to try to get immediate responses. Oct 22 00:02:42 hey jkridner .. any news on the upcoming arduino tre yet? Oct 22 00:03:03 loaded ubuntu 14.04 on beaglebone black, booting from SD card. Loaded ubuntu gui. When it boots I get the login screen when I login the screen freezes. If I move the mouse the screen flickers then looses the mouse Oct 22 00:08:58 veremit: not really. Oct 22 00:09:45 Guest85775: powered USB hub? Oct 22 00:09:56 no Oct 22 00:10:01 Guest85775: USB hub? Oct 22 00:10:20 no I have the keyboard directly into the bbb Oct 22 00:10:30 no mouse Oct 22 00:10:32 Guest85775: ah, and the keyboard has a hub built into it? Oct 22 00:10:39 or mouse built into it? Oct 22 00:10:39 then boot up with the mouse Oct 22 00:10:44 and move it Oct 22 00:11:26 mouse and keyboard are separate? Oct 22 00:11:28 i have a keyboard with a usb hub built in but it does not recognize this keyboard at all Oct 22 00:11:48 powering the BeagleBone Black off USB? Oct 22 00:12:03 so I just use the USB keyboard at the moment Oct 22 00:12:10 I suspect you need to provide more current into the BeagleBone Black by using the DC adapter and a 2A supply. Oct 22 00:12:30 It could be the power consumption causes the port to be cut off. Oct 22 00:12:33 oh Oct 22 00:13:05 i can login Oct 22 00:13:12 but, it goes no further Oct 22 00:13:15 if you have the ability to reach the terminal (via Ethernet, serial or otherwise), it would be interesting to see the kernel log (via dmesg, for example) Oct 22 00:13:46 power consumption might peak at that point. if you were running on the DC adapter with a 2A supply, I wouldn't suspect this. Oct 22 00:13:51 ssh in you mean? Oct 22 00:14:14 yeah, ssh would give you a terminal. Oct 22 00:14:28 run 'dmesg' and pastebin the output. Oct 22 00:14:37 ok hold fire Oct 22 00:22:10 ssh username and password the same?

Oct 22 00:38:36 guess you are using a bluetooth keyboard/mouse? Oct 22 00:39:00 no Oct 22 00:39:14 oh, I see "LiteON HP Basic USB Keyboard" earlier... Oct 22 00:39:25 just a usb one, just found a gruntier power source Oct 22 00:39:26 I wonder why Bluetooth is loading then. Oct 22 00:39:33 yep Oct 22 00:40:49 you can supply 2A via the usb? Oct 22 00:40:52 it matters if you are connecting over the DC barrel jack or the USB jack. The power management chip has a built-in current detection and limiting feature. It is typically configured to cut off at 1.3A on the USB port and 2.5A on the DC jack. Oct 22 00:41:07 ok Oct 22 00:45:02 ok, so I have put a dedicated supply to the usb port. It will now run the usb keyboard with integrated hub so mouse and keyboard running at once. screen still flashes when moving mouse Oct 22 00:45:16 ok, got a second bbb Oct 22 00:45:23 turns out my first bbb is just broke Oct 22 00:45:30 well, kinda Oct 22 00:45:37 usb kb is broke Oct 22 00:52:09 unplug ya usb connection to the beagle .. just use the dc jack .. ffs. Oct 22 00:54:31 veremit, i'd like to use a kb Oct 22 00:54:50 slave port not host :P Oct 22 00:56:12 sorry, i'm not understanding. what do you mean by that? Oct 22 00:56:30 don't use the little usb port .. only the big one :) Oct 22 00:56:43 and the round connector for power Oct 22 00:56:45 sheesh Oct 22 00:56:55 that's exactly what isn't working Oct 22 00:57:01 on one bbb Oct 22 00:57:06 did you change your beagle? Oct 22 00:57:08 and is working on the other bbb Oct 22 00:57:16 right .. so you have a broken beagle Oct 22 00:57:23 google rma beaglebone Oct 22 00:57:40 that's exactly what i said 12 minutes ago Oct 22 00:57:49 hurrah .. so we're learning, right?! :) Oct 22 00:59:01 Guest85775 .. did you plug a round connector into the black bit of your beagle yet? Oct 22 00:59:13 a dc jack ? Oct 22 00:59:21 NOT a usb Oct 22 01:01:26 veremit, just so you know, when you say "ffs" and "so we're learning, right?! :)" i find it aggravating Oct 22 01:01:43 and not cheeky or endearing or something else you might be going for Oct 22 01:02:25 ah I'm just frustrated everyone is lead to believe that they can run a bealge off the mini-USB cable with hubs and wifi and everything .. and its just NOT possible. Oct 22 01:02:57 so I'm sorry if I caused offence Oct 22 01:04:03 first thing you -should- do with your new beagleboard is get a 5V power adapter, a serial debug cable and THEN Start connecting things to it. Oct 22 01:04:50 it saves a lot of headaches that way when things dont' seem to work ;) Oct 22 01:05:07 I guess I'm just very used to working with embedded systems Oct 22 01:07:43 ah, i see Oct 22 01:09:04 that's good to know. i have a power supply now and a loaned ftdi cable. i guess i'll order my own ftdi cable Oct 22 01:09:25 debug cable is most useful when you ahve boot problems :) Oct 22 01:09:30 have* Oct 22 01:09:35 veremit, how do you feel about getting 2 of everything when dealing with hardware? Oct 22 01:10:11 its a good principle .. the probability of causing damage to one .. intentional or otherwise :) Oct 22 01:10:27 i've been building arduino robots and this has been really really helpful in cutting down troubleshooting times Oct 22 01:10:37 cool Oct 22 01:12:25 i've actually had this bbb sitting on my desk for quite some time, i don't think i can RMA it Oct 22 01:13:14 ahh Oct 22 01:21:01 ok so running 10w 5v supply, problem persists ffs guy Oct 22 01:37:56 possible to change display settings from ssh Oct 22 01:42:03 if you set DISPLAY=:0 should be able to Oct 22 01:48:29 don't count on that Oct 22 01:54:32 distros thesedays have outrageous permission settings **** ENDING LOGGING AT Wed Oct 22 03:00:00 2014
