**** BEGIN LOGGING AT Mon Nov 18 02:59:59 2013 Nov 18 04:21:56 Hi...Im struck with Beaglebone crosscompilation.. can anyone pls help me.. Nov 18 04:22:35 <_vicash_> Hello. I am using BBB with the stock Angstrom image. However, I have a small 4x3 LCD screen cconnected to it instead of HDMI and was wondering how to increase the Font size of the text on the login screen. How does one do that in the configuration or similar ? Nov 18 04:49:14 hi, i have installed arch to my sdcard and booted my BBB with it using this: http://archlinuxarm.org/platforms/armv7/ti/beaglebone-black, i'm not sure what IP to use at step 8 :\ Nov 18 04:51:24 lsm5: can you run ifconfig and see if you have a new interface? Nov 18 04:51:55 solarradiation: ifconfig -a only shows my already existing interfaces :\ Nov 18 04:52:25 you're connecting to the thing via usb, right? Nov 18 04:53:03 solarradiation: next to the ethernet port, there's a micro USB slot, i'm connecting from there to USB on my laptop Nov 18 04:53:17 solarradiation: or am i supposed to be using the usb port on BBB ? Nov 18 04:54:45 no, the mini usb port is the correct one, at least for angstrom... Nov 18 04:55:23 solarradiation: so btw, actually sometime back when both my emmc and sdcard were messed up, it did actually show an interface Nov 18 04:55:46 solarradiation: but now that i have bbb booted off of sdcard, it doesnt seem to do so Nov 18 04:56:24 maybe i should give angstrom a try Nov 18 04:58:09 solarradiation: thanks though, that atleast solves part of the problem :) Nov 18 04:58:41 you should try angstrom. btw, do youhave a ftdi cable or something so you can plug into the serial debug console? Nov 18 04:59:27 solarradiation: i think i need to get one, btw, is your angstrom booted from sdcard or emmc ? Nov 18 04:59:36 lsm5: and sometimes (10% of the time), even on angstrom, it does not show up as a ethernet device for some reason i've yet to figure out Nov 18 05:00:12 but i'm a noob to BBB, hopefully someone else will chime in Nov 18 05:00:29 lsm5: you can get the emmc flasher or the sd card boot version Nov 18 05:00:39 solarradiation: ohh ok, so i removed sdcard and tried to boot off of emmc, doesn't seem to boot, but the interface shows up :) Nov 18 05:00:49 flashing takes 40 min or something but worked better for me Nov 18 05:00:56 solarradiation: i see Nov 18 05:01:04 lsm5: that's probably angstrom booting from emmc Nov 18 05:01:14 (unless you somehow broke the emmc install) Nov 18 05:01:26 solarradiation: yup, i did break the emmc while trying to put debian Nov 18 05:01:45 solarradiation: the 4 user leds don't blink at all Nov 18 05:02:09 solarradiation: anyway, thanks for clearing this :) Nov 18 05:02:50 try flashing the emmc with the flasher on this page: http://beagleboard.org/latest-images Nov 18 05:03:09 solarradiation: cool Nov 18 05:03:14 solarradiation: will do, thanks Nov 18 07:45:10 always on the first partition, which is a FAT16 one Nov 18 07:45:15 argh Nov 18 09:19:27 Is anybody able to tell me the best way to copy a modified angstrom image from one BBB to another? Nov 18 09:19:52 as in, write it to the eMMC of the second beaglebone Nov 18 09:20:42 why does connman not show my usb-ethernet connection as a service? Nov 18 09:20:47 on my bbb Nov 18 09:20:58 if you have a uSD card tto boot from, just dd from one BBB to another Nov 18 09:22:16 can you just dd root? Nov 18 09:22:24 or do you have to do something special Nov 18 09:23:51 why not copy your few modifications? Nov 18 09:24:10 you can even mount both over the net and run a diff on the relevant files/folders Nov 18 09:24:37 I may end up having to do this on many (~20) BBBs Nov 18 09:25:00 so it can't be anuthing too time consuming Nov 18 09:25:06 *anything Nov 18 09:27:52 ? Nov 18 09:28:12 so flash them with stock image and then untar your changes on top Nov 18 09:31:50 is there not a way to create a flasher image that includes my changes? Nov 18 09:32:19 sure there is Nov 18 09:32:48 take stock flasher image, apply your diff on top and deploy Nov 18 09:33:18 pardon the stupid question but: how? Nov 18 09:34:42 jjc: you can just dd the entire contents of the eMMC Nov 18 09:35:25 you can even name it .img and use that fancy usb flasher from a linux box if you're so inclined Nov 18 09:36:35 i'm afraid i don't know what the fancy usb flasher is Nov 18 09:37:27 I can't find it now Nov 18 09:38:11 https://github.com/ungureanuvladvictor/BBBlfs Nov 18 09:38:39 ty Nov 18 09:38:47 it basically boots your BBB over usb and flashes an image you give it Nov 18 09:38:55 without making uSD cards or anything Nov 18 09:39:21 the guy who made it is vvu on this channel Nov 18 09:39:29 note that it only works for images that fit SDRAM Nov 18 09:39:31 so thank him if / when it works Nov 18 09:39:33 AFAIK Nov 18 09:39:38 av500: ah. ouch. Nov 18 09:41:03 Hi, I am interfacing a sensor (IMU) with bbxm over i2c bus 2. I can do i2cdump, however the sensor values remain the same, even when I move it. I feel that the sensor is not overwriting the values on the i2c bus. Any particular reasons for the same? Nov 18 09:41:55 psyr: this has nothing to do with BBB but I would imagine the IMU has some registers that you read over i2c.. but there's probably another i2c command to tell the IMU to update those registers with current values Nov 18 09:42:07 i2c bus is not persistent ;) Nov 18 09:42:19 so the values are sitting on the IMU and not changing there Nov 18 09:42:19 Vaizki: that should be available in the datasheet then. Nov 18 09:42:24 cool Nov 18 09:42:25 thanks Nov 18 09:42:31 yes I would have imagined that you'd look there first... Nov 18 09:42:35 i will go through them again. Nov 18 09:42:40 sorry, noob here. Nov 18 09:43:25 Vaizki @av500 thank you very much for your help Nov 18 09:44:09 jjc: as av500 said, it may be that the images cannot be bigger than what fits in memory Nov 18 09:44:17 with the BBBlfs Nov 18 09:44:36 which is a problem if you dd the entire eMMC off an existing BBB Nov 18 09:45:07 Vaizki i have a .img file which is 1.78GB so i'm hoping it should be okay Nov 18 09:45:07 you can still flash with SD card Nov 18 09:45:35 Can I power the beaglebone black with a 5vDC adapter and still plug in the USB that also provides power, or is that bad? Nov 18 09:45:35 also, the USB flasher can be adapted to work with larger images Nov 18 09:45:41 novakitty: you can Nov 18 09:46:04 @av500: thank you Nov 18 09:46:22 @av500: can you point me towards help for the uSD flashing? it's always nice to have a backup Nov 18 09:46:30 ? Nov 18 09:46:34 the stock flasher Nov 18 09:46:37 no? Nov 18 09:47:01 novakitty: the PMIC on the BBB will prefer the 5V barrel jack Nov 18 09:47:37 Vaizki: Ok thanks Nov 18 09:47:55 @av500 okay Nov 18 09:48:11 not sure if you can actually unplug the 5V barrel jack and have it automagically fail over to USB power without booting .. maybe Nov 18 09:48:30 question about powering BBB: will a powered usb hub be enough to power a usb wifi dongle? Nov 18 09:48:55 sure Nov 18 09:49:02 and by that i mean: power the bbb with a powered usb hub, and plugging in a separate usb wifi dongle Nov 18 09:49:18 ah Nov 18 09:49:24 Vaizki: But I should be able to connect and disconnect the USB cable while it's powered on with the 5vDC cable? Nov 18 09:49:30 yes Nov 18 09:49:37 novakitty: yes Nov 18 09:49:37 plug the BBB and the wifi both into the powered hub. the plug the hub's host cable into the BBB usb Nov 18 09:49:45 (not powering the usb wifi dongle with a usb hub as well (since that's obviously possible)) Nov 18 09:50:09 Vaizki: then the BBB can even see itself over USB Nov 18 09:50:19 yes Nov 18 09:50:19 like to exchange data with itself Nov 18 09:50:23 boneception Nov 18 09:50:30 solarradiation: it can depend alot on the hub and it's power source...some are really bad. Nov 18 09:50:41 av500: nothing wrong with a little self help... Nov 18 09:51:22 novakitty: not sure about the kernel support for usb removal/insertion on the sitara Nov 18 09:51:42 I had some major issues with it not recognizing anything inserted after boot Nov 18 09:51:44 novakitty: the main thing I'm wondering is: if the beaglebone can draw more current from the micro-usb plug, can it use it? Nov 18 09:52:00 Vaizki: as long as trying it won't blow anything up Nov 18 09:52:22 you can force the BBB to draw more than spec'd amounts of power from usb Nov 18 09:52:40 but make sure the other end of the usb can handle it :) Nov 18 09:54:23 Okay I did it. I don't smell fire and the storage device appeared in explorer. Thanks again! Nov 18 09:54:35 http://www.ti.com/lit/ds/slvsb64f/slvsb64f.pdf Nov 18 09:54:41 that's the PMIC in the BBB Nov 18 09:55:27 1800mA is the max current that you can set for the USB DC input draw Nov 18 09:56:46 Vaizki: ooh, nice, thanks for link (not that I can understand more than 5% of it!) Nov 18 09:56:58 it's a fun trip to learn Nov 18 09:57:07 POWER PATH CONTROL REGISTER (PPATH) Nov 18 09:57:10 make sure that your cable can deal with it Nov 18 09:57:19 that controls how much power the BBB will draw Nov 18 09:57:55 my uEnv.txt has this in uenvcmd.. if test $board_name = A335BNLT; then i2c mw 0x24 1 0x3e; Nov 18 09:58:04 and I also got cpan installed on my BBB, i am now unstoppable Nov 18 09:58:11 basically writes 0x3e to the power path control register on the PMIC Nov 18 09:58:27 allowing the BBB to draw 2.5A from 5V jack and 1.3A from USB Nov 18 09:58:37 write 0x3f to allow full 1.8A Nov 18 09:59:08 and yea your cable, hub, pc or wall wart may melt. Nov 18 09:59:12 not my problem, Nov 18 10:01:08 you mean /boot/uEnv.txt ? Nov 18 10:04:26 Can I make the beaglebone black boot from a SD card but run the root files off a usb powered hard drive? Nov 18 10:05:09 novakitty: that should be possible for any linux Nov 18 10:05:34 solarradiation: if you have to ask don't touch it :D Nov 18 10:05:59 I managed it with raspberry using a cmdline.txt file, but I'm guessing that won't apply here. Nov 18 10:06:06 Vaizki: fair enough, don't plan to -- but can you point me to some docs? Nov 18 10:06:12 solarradiation: you can Nov 18 10:06:18 uEnv.txt Nov 18 10:06:19 google.. and it's the uEnv.txt on the first partition of the flash device.. I think ångström has a second uEnv.txt in the root fs Nov 18 10:06:46 which is never used by the boot, I don't know why the hell it's there Nov 18 10:16:13 So one of the first things I did with my new BBB was to run 'opkg update && opkg upgrade' this resulted in problems booting and I ended up having to reflash the mmc. Is there a way to successfully update everything? Nov 18 10:18:55 do you have a debug serial usb cable? Nov 18 10:19:17 No I'm afraid not Nov 18 10:19:42 get one.. it's worth it Nov 18 10:20:12 I will pick one up Nov 18 10:20:45 I read something about a DNS issue someone had...my problems may have been similar, im not sure Nov 18 10:21:37 Initially the update process looked like it was going well..but when I returned to the console there were errors suggesting i had not run opkg update first...yet I had. Nov 18 10:24:32 What can I do with a serial debug cable? Nov 18 10:24:46 see what happens at boot and if it's broken fix it Nov 18 10:26:37 Ah. I see. I'm pretty in the dark still, I'm waiting on the HDMI adapter. Nov 18 10:26:40 With a serial debug cable, you're sitting on the trunk side of the branch as you're sawing it off. Without a serial cable, you're on the other side. :P Nov 18 10:26:59 lol Nov 18 10:27:01 novakitty: you get a serial console-- it's like having a monitor/keyboard connection Nov 18 10:28:04 do i connect with putty? Nov 18 10:28:14 or something Nov 18 10:28:40 hello :-) Can i run a program compiled for raspberry pi on my beaglebone black with debian? Nov 18 10:28:41 Any old comms program, the serial debug cable is just a 3.3V RS232 line. Nov 18 10:29:33 Eg. I use picocom, but they'll all work. Nov 18 10:29:40 oh i see...so i need to recall old modem terminal emulator stuff Nov 18 10:29:59 novakitty: yes, putty will work. set it for 115200 8n1 Nov 18 10:30:34 cool thank you all for the tips Nov 18 10:31:02 novakitty: i use this and it works great: https://www.sparkfun.com/products/9717 Nov 18 10:31:46 Ditto, the FTDI cable but from a different supplier here. Nov 18 10:31:53 the BBB has separate headers for the serial debug console so you just plug it right in Nov 18 10:32:48 Could also use one BBB as a serial interface for another. Nov 18 10:34:34 I'll probably try to ditch the headless thing and get a monitor and input devices connected soon...but that would be good to have too. Nov 18 10:35:16 Can I run armv6 code on my beaglebone black? Nov 18 10:35:59 Don't think so, except by emulation. All the old instructions are missing from the ARMv7 core I think. Nov 18 10:36:42 http://26-26-54.hardwarebug.org/30 Nov 18 10:37:09 bummer :-( I run Kisslicer on my raspberry, but want to run it on my beaglebone to :-( It's closed source Nov 18 10:37:36 Russ: That's also known as Coen's Rule #1 For Being as Unhelpful as Possible. Nov 18 10:38:57 its buch better than listening to someone's random guess on irc Nov 18 10:39:27 How long do I have to pretend I like Angstrom before I run to Debian or Ubuntu? I just finished installing sudo because I felt naked. Nov 18 10:41:02 Russ: It evolves down into IRC responses ending up being nothing more than "Answer: check http://gooogle.com". And random web pages are no guarantee of accuracy either. Nov 18 10:41:37 fiola, if you don't know, don't guess Nov 18 10:41:51 checking google.com would very quickly give the correct answer in this case Nov 18 10:42:00 That's why people come to a dedicated channel, for more likely correct info. Nov 18 10:42:21 Russ: Well if you know the answer, how about giving it? Nov 18 10:42:49 And while you're at it, if you know an answer to be incorrect, how about correcting it? Then everybody learns. Nov 18 10:43:07 does sort of seem to be the point of an irch channel Nov 18 10:43:11 irc* Nov 18 10:43:14 Yep Nov 18 10:44:34 you ever google something, then find a forum on the subject, with and answer from someone to go and google it? Nov 18 10:45:20 http://lmgtfy.com/?q=armv7+backwards+compatible Nov 18 10:45:44 novakitty: Yeah, and it's irritating as hell. But that's IRC for you, often full of unhelpful people who think that telling people to google is "help". Nov 18 10:45:54 it is help Nov 18 10:45:59 people don't google, its crazy Nov 18 10:46:27 fiola: well there's a fine line between "being helpful" <-> "people just wanting to be spoonfed" Nov 18 10:47:04 fiola: i agree that "RTFM" or "just google it" is not always the final answer, but for trivial cases i think they are valid. Nov 18 10:47:44 Google is the last LAST of resort, not the first. First you go to the sites dediated to a topic, and if you want IRC, for BBB that would be this listed IRC channel. It's only when you don't know what the dedicated sites are that you google for them. Nov 18 10:48:06 exactly what I said, people don't bother to type it into google Nov 18 10:48:36 And why should they type it into Google, when they know an authoritative place already? Nov 18 10:48:58 You never go to a *generic* place first, that's idiotic. Nov 18 10:49:08 are you being sarcastic or something? Nov 18 10:49:15 oO( "Google is the last LAST of resort" )... sorry, but for anyone active working with technology nowadays, this is so unrealistic that even discussing it is a waste of time. Nov 18 10:49:15 forums and irc are authoritative? Nov 18 10:49:35 Russ: Jason often sits here, so this place can be authoritative, yes. Nov 18 10:49:41 its "reality" versus "the world is a perfect place." Nov 18 10:49:56 if you want authority on ARM, the only place to go is the ARM ARM Nov 18 10:50:01 and google can find that for you Nov 18 10:50:09 BBB is the topic, not ARM. Nov 18 10:50:35 ok, then the TRM, SRM, and schematics are authoritative Nov 18 10:50:47 yeah I came here to try to glean info about how to use a BBB, not a lennon on how to google Nov 18 10:50:52 and because its a cortex-a8, the arch manual, and again, the ARM ARM Nov 18 10:50:53 lesson* Nov 18 10:51:20 Why you're doing your level best to avoid providing direct help, I'll never understand. That's pretty much why BBB peeps move off Angstrom as soon as they can. The help just isn't there. Nov 18 10:51:28 IRC is great for when you get stuck, want to find out what people are doing, or want to bounce ideas around Nov 18 10:51:55 It's also great when people want to help. Nov 18 10:52:26 Just because you and Koen don't want to help, doesn't mean that others don't. And Jason is often helpful here. Nov 18 10:52:31 but only if they know the answers Nov 18 10:53:06 fiola: its really great that you feel like this. but let me ask one thing. how long have you actually been an active, unpaid supporter - e.g. doing this out of the goodnees of your heart, in your spare time? Nov 18 10:54:31 LetoThe2nd: Are you saying that the old timers are too jaded to continue helping? Well, maybe. But that's no reason to say "google it" instead of answering a known question. Why sit here at all otherwise. Nov 18 10:54:49 fiola: i am not saying anything, you are evading my question. Nov 18 10:55:31 LetoThe2nd: I'm not answering your question because it's ill-framed, since I'm not support. Ask it of someone who does support. Nov 18 10:56:17 learning to use google is a very important and valuable technical skill Nov 18 10:56:46 fiola: sigh. see - the problem is that you claim to know better how to behave than many people, who have spent considerable amount of their spare time here, providing help and knowledge for free. Nov 18 10:57:05 It's a very important skill for use AFTER you consult the more likely expert sites and they fail you. Nov 18 10:57:25 fiola, consulting a website doesn't cost anyone's time Nov 18 10:57:25 fiola: as a person having done years of enduser support now, i can understand you. thats fine. i often see new people arriving, being eager to do good support, and that is a giid thing. Nov 18 10:57:31 *good thing. Nov 18 10:57:51 sometimes you google something and wind up reading irc chat logs..sort of a chicken and egg thing Nov 18 10:57:59 fiola: the point is - after some years, you tend to get tired. tired of answering the same basic, and basic stuff over and over again. Nov 18 10:58:01 LetoThe2nd: Kunzu asked a question, and didn't get an answer, so I tried answering. One can't do more than try. It's far better than telling someone to google. Nov 18 10:58:06 fiola, also, the expert site on arm architecture is arm.com, and the answer is there Nov 18 10:58:24 fiola, telling someone the wrong answer is better than google? Nov 18 10:58:39 fiola: thats only right partially. spreading half-knowledge is bad and often harmful. Nov 18 10:58:48 LetoThe2nd: So put a FAQ in the /topic line. A lot of channels do that to avoid answering FAQs repeatedly. Nov 18 10:58:55 its good to engage, but it isn't better than going to google Nov 18 10:59:05 you did mention that you weren't sure, which is good Nov 18 10:59:24 fiola, no one reads the topic Nov 18 10:59:33 lol Nov 18 10:59:41 seriously Nov 18 10:59:47 fiola: i'm sorry, but i have to agree with Russ here. no one reads the topic. Nov 18 11:00:27 Well that can't be helped, but for the (small?) proportion that do read the topic, it can help. Nov 18 11:00:37 fiola, in fact, one of the easiest way to answer people's questions on IRC is to google it for them Nov 18 11:00:53 fiola: which is why i asked if you actually ahve supported more than a few days or weeks. if not, thats fine - go ahead and do a good job, its great to see people being enthusiastic. Nov 18 11:01:10 fiola: but on the other hand. pllease do not judge the more experienced ones so easily. Nov 18 11:01:18 fiola, its a good way to learn too, answering people's question by researching it Nov 18 11:01:33 * LetoThe2nd has made his point clear then. back to work. Nov 18 11:02:11 I've been here intermittently since my BBWhite days. I help when I can, and that's always when I'm actually looking at a channel. Nov 18 11:22:53 I only have SSH to interact with my BBB right now. Can I use X11 Forwarding to run gnome or whatever angstrom uses for DE? What would the command be to load the DE without loading X also? Nov 18 11:24:12 NovaCat: you can ssh with the -X flag (X forward) and run individual programs graphically Nov 18 11:24:24 Something along the lines of startxfce4, startldxe, etc Nov 18 11:24:29 ssh -X shuold work. but usually its more wise to just fire up the specific application that you want. Nov 18 11:24:30 you can also probably set up vnc Nov 18 11:24:44 (instead of the full DE, that is.) Nov 18 11:25:41 in fact, google 'beaglebone black vnc' Nov 18 11:25:55 I'm using putty right now, logged into my raspberry using the full DE running xchat Nov 18 11:26:06 it actually works quite well Nov 18 11:26:15 faster than running a DE directly on the Pi Nov 18 11:26:24 so you have X11 installed on your windows host? Nov 18 11:26:32 xming Nov 18 11:26:38 yes Nov 18 11:26:53 all that talk about the PMIC earlier.. has anyone seen progress on the BBB suspend/resume front? Nov 18 11:26:56 and you're running an entire DE over... ssh? Nov 18 11:26:58 using the full xfce desktop right now Nov 18 11:27:04 yes Nov 18 11:27:18 no compositing but its alot better than any vnc ive ever used Nov 18 11:27:24 didn't know you could run full de's over ssh Nov 18 11:27:30 wait then what are you askign? Nov 18 11:27:31 its not tryign to encode jpg image info and transmit it Nov 18 11:28:02 im asking what the command to launch the default angstrom DE would be, other than using startx...since i really already am runnign x Nov 18 11:28:38 in the case of xfce i can use either startxfce4 or xfce4-session...its similar for other Des Nov 18 11:33:27 NovaCat: looks like angstrom uses gnome Nov 18 11:33:30 so gnome-session? Nov 18 11:36:47 hiiiiiiiiiiiiiiiiii i am unable to get BB-UART file in /lib/firmware Nov 18 11:36:58 wt can i do for this sir Nov 18 11:37:30 first: calm down Nov 18 11:37:33 lippy: what exactly are you trying to do there? Nov 18 11:37:38 second: have some good swiss chocolate Nov 18 11:37:44 third: provide more info Nov 18 11:38:53 i wana open two uarts at time so that if send any information in uart 1 so that it can post in uart2 for this in hardware level i shorted pins of uatr1tx and yart2 rx and vise versa Nov 18 11:39:08 solarradiation: i can't recall if i tried that yet...I tried a few guesses but guessing didn't work. My /etc/X11/default-display-manager file contains /usr/bin/gdm I think Nov 18 11:39:12 argh my head hurts from trying to track these sleep/resume threads in different forums Nov 18 11:39:50 apparently people have been able to put the BBB into sleep and wake it up again but nowhere can I find any examples or docs Nov 18 11:39:55 actly i and my sir working he is getng the same thing but i am unable to Nov 18 11:40:07 if i get that file means i can do Nov 18 11:44:05 any body can plz help me out for this..how can get dat source file Nov 18 11:44:34 lippy: first you should make sure they are muxed properly Nov 18 11:44:45 ya Nov 18 11:44:47 and then it's just to read/write the files in /dev Nov 18 11:45:23 i am not getng wt u r saying Nov 18 11:45:54 your keyboard seems to be loosing characters. Nov 18 11:45:55 i wana two uarts at tym working one for trasmintion it should recev the other Nov 18 11:52:36 you want loopback? Nov 18 14:54:07 anybody has experience trouble downloading pdf data sheets from the TI web? Nov 18 14:54:21 experienced* Nov 18 14:54:58 nope Nov 18 14:55:11 their webservers are usually very well maintaine Nov 18 14:55:13 maintained Nov 18 14:55:30 you sure your internet access doesnt suck? comming from africa and all? Nov 18 14:55:41 ;-> Nov 18 14:56:49 haha, thank you, just tested with another browser and works. My mistake Nov 18 15:28:45 oh my beagle!! Nov 18 15:49:31 my bbb showing and going hdmi output Nov 18 16:15:46 hello there im trying to disable the console of the beagleboard on ttyO2 so i can use it as a com port, im using ubuntu 13.04 Nov 18 16:16:32 i changed the uEnv file and moved somewere else the file /etc/init/Serial.conf Nov 18 16:16:40 but still cant be deactivated Nov 18 16:16:48 am i doing smth wrong ? Nov 18 16:16:50 thanx Nov 18 16:17:39 im using a beagle board xm Nov 18 16:17:54 anyone had the same trouble Nov 18 16:17:56 ? Nov 18 16:18:22 how do you mean it can't be deactivated ? Nov 18 16:18:30 in which respect does it stay on ? Nov 18 16:20:24 when i do root@arm:/home/ubuntu# dmesg | grep tty [ 0.000000] console [tty0] enabled [ 0.881927] omap_uart.0: ttyO0 at MMIO 0x4806a000 (irq = 88) is a OMAP UART0 Nov 18 16:21:06 yes, thatr means the kernel find the hardware ... Nov 18 16:21:24 you would have to recompile the kernel to not make it use the driver to actually turn this off Nov 18 16:21:55 which is not what you want Nov 18 16:22:09 (but since you actually want to use the device ....) Nov 18 16:24:14 hmm one week ago i did the same thing and it worked but now i installed a new sd card with the same ubuntu 13.04 and it is not deactivating it Nov 18 16:24:27 thats weird Nov 18 16:24:49 what exactly isnt deactivating (beyond the driver itself like above) Nov 18 16:25:12 you have to be a bit more specific Nov 18 16:26:09 sorry i mean i want to disable the console so i can use the com port for other purposes Nov 18 16:26:35 is there anyother way apart from recompiling the kernel? Nov 18 16:27:36 the console login is handled by upstart ... grep ttyO2 /etc/init/* ... add a file with the same name but replace the .conf suffix with ".override" and put the line "manual" inside Nov 18 16:28:16 the console during boot is handled by kernel commandline args "drop the console= arg from your kernel commandline" Nov 18 16:29:00 the console before booting is handled by uboot ... you have to change the code in there if you dont want the console initialized at all Nov 18 16:29:16 ok i will try that , the uEnv.txt i already commented out the console args Nov 18 16:29:37 thanks Nov 18 16:29:38 and if you want to make *any* use of the device, you do still want to keep the kernel driver enabled Nov 18 17:14:28 Hi. My BBB with MPD on Debian Wheezy is great, but it's time to add audio recording / CD ripping. Is Audicious the way to go? Nov 18 17:16:01 Sorry - I meant AudAcious Nov 18 17:40:11 Hey, im just getting started with a new BBB, got archlinuxarm running but i seemn to have some trubble getting the usb2ether connection up, any help trubleshooting would be awsome Nov 18 17:52:05 bluesman: I'm not familiar with AudAcious. Are you using keyboard/monitor with it or some non-X remote access? Nov 18 18:34:16 Hello Nov 18 18:35:26 efgh Nov 18 18:35:39 ehlo Nov 18 18:36:04 Please give me hints how to patch inbuilt Angstrom in Beaglebone Black with Xenomai ....Please Nov 18 18:36:32 Hi, Levi. Right now, I'm using MPDroid on an old phone as my controller. But I expect to use a monitor for recording. Audiacious is apparently packaged with my Debian install. It looks a lot like Audacity (the recording program I use on my PCs). Nov 18 18:36:34 1) build angstrom by following the steps on the website Nov 18 18:36:41 2) learn all about xenomai Nov 18 18:36:50 3) apply xenomao patches to angstrom kernel Nov 18 18:37:16 north xenomao is best xenomao! Nov 18 18:37:34 xenomorph is bester Nov 18 18:38:45 Which website ? Nov 18 18:39:08 av500 xenomai is hunting us back Nov 18 18:40:03 hm I will sneak up at which kernel they are now Nov 18 18:40:11 http://www.angstrom-distribution.org/ Nov 18 18:41:00 lol funny release notes Nov 18 18:41:03 upgrade to support I-pipe patches to Linux 3.8, and Linux 3.10 Nov 18 18:41:03 (not included); Nov 18 18:41:43 hm so at least 3.8 should work Nov 18 18:44:19 Thanks a lot !! Nov 18 18:44:58 hm there is even -rt branch for 3.7 Nov 18 18:45:00 ups 3.8 Nov 18 18:45:11 but koen did not updated it in 6 months Nov 18 18:49:18 <`Ishq> If I want to use the beaglebone to signal a relay, can I use a diode instead of a transistor to protect the beaglebone? Nov 18 18:49:33 * `Ishq is really new to electronics... Nov 18 18:51:33 The diode protects the transistor.. Nov 18 18:51:45 but the relay coil needs much more power than the beagle can supply Nov 18 18:52:35 so you use a transistor to amplify that. Nov 18 18:52:51 <`Ishq> Ah, I see. Nov 18 18:53:31 <`Ishq> I have only used opamps to amplify voltage. Shame this lab doesn't have any transistors. Nov 18 18:53:49 thi...what? Nov 18 18:53:57 find a different lab :P Nov 18 18:54:07 <`Ishq> My school lab. My senior project :p Nov 18 18:54:18 <`Ishq> Now I need to wait to buy one :( Nov 18 18:54:29 find an EE to collaborate with. Nov 18 18:54:38 How does your lab not have a transistor or two? Nov 18 18:54:44 Or buckets of them? Nov 18 18:55:00 buckets are for folks taking in surplus components. ;) Reels would be more likely.. Nov 18 18:55:00 <`Ishq> Maybe we do. But when I asked, he said we don't. Although, I distinctly recall using one last year... Nov 18 18:55:00 I mean,. the 2N2222 is in many cases literally cheaper than dirt. Nov 18 18:55:17 Ask for a mosfet instead? Some people forget what it stands for.. Nov 18 18:55:36 <`Ishq> Maybe. I'll try. Nov 18 18:55:40 ^^^ Nov 18 18:55:43 <`Ishq> Thanks. Nov 18 18:55:50 MOSFETs are better for this application anyway. Nov 18 19:06:16 use a tube Nov 18 19:06:27 and a thyratron to switch Nov 18 19:48:51 Hello silly question- is there a way to bring the BBB back to factory settings? I've re-flashed the board twice but its still challenging me for a password? Nov 18 19:52:01 emmc or sdcard? Nov 18 19:53:31 Hi Guys, anyone have any experience with wifi and connman? Nov 18 19:53:59 I have experience with wifi Nov 18 19:54:19 I am finding I have to do a "ifup wlan0" to get connected, I thought connman would do that .. Nov 18 19:56:16 woglinde: My /var/lib/connman/settings has wifi enabled and I have a wifi.conf file with my network details .. Nov 18 19:56:17 my experience with connman is to disable it. Nov 18 19:56:50 I use static ip's Nov 18 19:56:52 djlewis: So what is a better tool for wmbedded devices? Nov 18 19:57:02 I need dhcp Nov 18 19:58:11 with a custom built rtl8192cu driver dhcp works fine, just connman doesn't enable the interface Nov 18 19:58:18 brm that you are familiar with Nov 18 19:58:42 woglinde: Huh? Nov 18 19:58:46 Hi Nov 18 19:59:02 ifup/down, selfwriten shell scripts, networkmanager or wicd Nov 18 19:59:21 EMMC Nov 18 19:59:26 this cable does works with beagle bone? Nov 18 19:59:27 http://dx.com/pt/p/micro-hdmi-male-to-vga-female-converter-adapter-black-147251#reviews Nov 18 19:59:27 maybee I forgot something Nov 18 19:59:41 So how do I get connman to auto start my wifi interface, I have ethernet disconnected Nov 18 19:59:57 celso boot from sd-card mount emmc edit /etc/passwd and voila not password needed anymor Nov 18 19:59:59 e Nov 18 20:00:42 Ah ha... Thank you for the suggestion! Nov 18 20:00:58 brm btw. there was a feature in conman not enabled in openemebdded/angstroem for a long time maybee you hit this Nov 18 20:01:08 But if I wanted to nuke the board is there a secret way to do so? Nov 18 20:01:09 I would like to get connman working, as it has other features I like, and is light weight Nov 18 20:01:38 woglinde: what feature? Nov 18 20:01:56 I am using a custome image .. not angstom Nov 18 20:03:37 brm can not rememeber search the oe mailinglisr Nov 18 20:03:53 brm or just disable connman and use ifup/down Nov 18 20:04:00 woglinde: did it break it or make it work? Nov 18 20:04:13 working something Nov 18 20:04:42 thanks will check out the list Nov 18 20:49:02 I am trying to build the Angstrom kernel modules from within /usr/src/kernel/ using "make ARCH=arm modules" but I am getting the error "make[1]: *** No rule to make target `kernel/bounds.c', needed by `kernel/bounds.s'. Stop." Any clue what theissue here is? Nov 18 21:06:21 back, did I miss any responses? Nov 18 21:07:17 nope Nov 18 21:08:17 under_wdeisey are sure you have the source code installed and not only the headers? Nov 18 21:10:19 no, I am not sure, but that sounds like it might be the issue Nov 18 21:18:01 woglinde how would i go about verifying that? Nov 18 21:18:42 search for .c files Nov 18 21:18:46 is there any way to search beagleboard IRC archives? (http://beagleboard.org/chat) Nov 18 21:19:02 or check for arch/arm/boot dir Nov 18 21:19:14
