**** BEGIN LOGGING AT Sun Jul 14 03:00:00 2013 Jul 14 04:44:50 Has anyone ever managed to get a java applet to run in any of the browsers included with the BBB? Java (OpenJDK JRE) seems to be installed correctly. Jul 14 04:55:19 you are using a BBB to run a browser? Jul 14 05:07:01 Yes - I'm just using the browsers included in the Angstrom distribution Jul 14 05:09:38 I downloaded all of the .ipk files and installed them in order using opkg, but I can't locate a opkg package for the plugin needed to run java applets within the Firefox or Chromium Jul 14 05:22:58 UncleBrian_: are you using a BBB, as a repalcemnt for a pc? Jul 14 05:36:17 hey folks, does teh TI boards really need a special lsdcard layout based on legacy patition layouts of cylinders, sectors, and heads? Jul 14 05:36:33 * masta was reading the mkcard.sh script and wondering Jul 14 05:40:36 I wasn't trying to replace a PC, but I was curious if I was missing something on the install. If the browser is there, and the Java plugin could be made to work, it would present some interesting options. It does run at 1GHz... Jul 14 05:53:51 UncleBrian_: yes, plenty of options.. I'm not sure if using it as a primary worksurface is an optimal use for it Jul 14 05:57:58 Agreed - mostly I was also concerned that I missed something in my Java installation. I didn't know if anyone else was able to *easily* make the Java plugin work. If it's a completely unrealistic and esoteric endeavor, I'm probably happy to quite trying... :( Jul 14 05:58:00 :) Jul 14 06:17:58 mrpackethead: thanks. Jul 14 06:18:31 UncleBrian_: i'm not sure to be honest, i'm a debian user Jul 14 06:18:44 and i'm not running any GUI's on mine Jul 14 06:19:07 there are ubuntu installs and i'm sure that they have all the widgets Jul 14 06:27:00 mrpackethead: that's probably the best way for me to look at it. I've got everything else working well. I though it would be nice to be able to use minicom to act as a dumb terminal to free up all of my main screen when I work with small ATmega parts. I'm sure I can make that work with Angstrom. Thanks again. Jul 14 06:28:03 you could do that i guess Jul 14 06:33:39 I have stock firmware on a beaglebone black and unsure about how to mount the MicroSD slot. I'm not trying to boot off of it, trying to use it as a seperate mounted partition Jul 14 06:34:18 Also dont see any mmcblk's besides mmcblk0 in /dev Jul 14 06:49:34 what is "stock" firmware Jul 14 07:15:59 mrpackethead: Angstrom, Linux beaglebone 3.8.13 Jul 14 08:12:25 dfadfa Jul 14 08:32:24 ficode: i had to do two things to have a microSD card mounted on /home on bbb Jul 14 08:33:10 1. the card needs to be in the slot during boot, i haven't found a way to make the kernel detect the card when inserted later Jul 14 08:33:21 What's the min baudrate the bbb uarts will run at? I jusr tried 50 baud and it did not work. Jul 14 08:33:45 2. mmcblk0 gets renamed to mmcblk1 when the card is in, and uboot can't find the onboard root filesystem Jul 14 08:34:11 so i modified the root=/dev/mmcblk0 to ..1 in uEnv.txt Jul 14 08:36:32 s/uboot/the kernel/ Jul 14 08:53:27 <_SY_> hello Jul 14 08:54:20 moin _SY_ Jul 14 08:54:28 _SY_: you got your fstab line wrong Jul 14 08:54:53 chocolateman Jul 14 08:55:01 kiwiman! Jul 14 08:56:32 mmm kiwi chocolate Jul 14 08:56:46 hmm... Jul 14 08:56:57 * KotH takes a note to propose that to läderach Jul 14 08:57:36 "We're not gonna spoil our chocolate with those over-sized gooseberries!" Jul 14 08:57:49 ha ha Jul 14 08:58:12 they have chocolate with raspberries :) Jul 14 08:58:17 <_SY_> sorry KotH, was watching something, I've rebuilt both BBB's, but haven't got fstab working...had to use FTDI to get it back....not sure what I'm doing wrong...the first time I did it, worked first time, pitty my notes are rubbish Jul 14 08:58:30 at least you do notes :/ Jul 14 08:59:16 <_SY_> I've got a good evernote on BBB...the fstab bit needs correcting Jul 14 09:01:03 <_SY_> if I run fdisk -l, it shows me that /dev/sda is 32 GB, which is correct Jul 14 09:02:04 <_SY_> I've created a folder in mnt called usbstick and created a shortcut to that: ln -s /mnt/usbstick /usbstick Jul 14 09:02:10 <_SY_> ls -ld /usbstick Jul 14 09:02:28 <_SY_> but my fstab entry only prevents the BBB from boothing. Jul 14 09:02:40 a few things you made wrong: Jul 14 09:02:52 and are swapped Jul 14 09:03:11 you cannot mount onto a symlink, you can only mount to a directory Jul 14 09:03:23 <_SY_> ok, so would this be correct: Jul 14 09:03:37 i would not create a subdir to /mnt/, but that's mostly my preference Jul 14 09:04:06 <_SY_> "/dev/sda /mnt/usbstick auto rw,defaults 0 0" Jul 14 09:04:17 looks ok Jul 14 09:04:32 but i think most usb sticks are partitioned, so it would be /dev/sda1 Jul 14 09:05:12 <_SY_> will try it now, if that doesn't work I'll try sda1 Jul 14 09:13:15 <_SY_> i've stried both "/dev/sda" and "/dev/sda1" it won't boot normally with either. Jul 14 09:15:03 How do I permanently enable a serial port? I followed this but it stopped working http://hipstercircuits.com/enable-serialuarttty-on-beaglebone-black/ after a reboot Jul 14 09:16:03 <_SY_> Willdude123: To enable at boot, edit uEnv.txt in /media/BEAGLEBONE/ Jul 14 09:16:22 And change what? Jul 14 09:16:23 <_SY_> you may need to mount this, mount /dev/mmcblk0p1 /media/BEAGLEBONE Jul 14 09:16:34 K Jul 14 09:16:39 <_SY_> What UARTS have you enabled? Jul 14 09:17:14 uart4] Jul 14 09:17:55 <_SY_> change line to read: optargs=quiet drm.debug=7 capemgr.enable_partno=BB-UART4 Jul 14 09:18:41 Also, I have opened a port at 50 baud, but it is going much much much faster. Jul 14 09:18:50 Not even sure it'll do 300 Jul 14 09:19:41 <_SY_> You need to make sure you are using the same baud rate at both ends of the link...The BBB defaults to 115K Jul 14 09:20:29 _SY_: There is no link, as such Jul 14 09:20:39 It's a one way system Jul 14 09:21:08 I *need* to use 50 baud. Jul 14 09:21:31 <_SY_> The link represents the serial cable which is connected to the BBB and another system... Jul 14 09:21:58 Willdude123: you have to configure both uboot and the kernel to use 50 baud Jul 14 09:22:05 Willdude123: but why the heck such a low baud rate? Jul 14 09:22:10 Well. Jul 14 09:22:20 I'll start at the very beginning. Jul 14 09:22:31 High Altitude Balloons. Jul 14 09:22:41 <_SY_> lewis1802 Jul 14 09:22:48 ShadowJK: there is one of your friends :) Jul 14 09:22:50 SpeedEvil: Help me out here Jul 14 09:23:09 Willdude123: what's the prob with the baloon? Jul 14 09:23:12 What happens is the balloon transmits data over a radio module/ Jul 14 09:23:20 Usually GPS data. Jul 14 09:23:34 Sometimes pictures. Jul 14 09:24:12 oh.. i see Jul 14 09:24:14 hmm.. Jul 14 09:24:16 ok Jul 14 09:24:28 To transmit data we use the Radiometriz NTX2 (mostly), which works by moving a pin up and down, which varies a frequency to make bits. Jul 14 09:24:32 i guess you are not using the debug serial port for this, then? Jul 14 09:24:41 No, UART4 Jul 14 09:24:47 hmm.. Jul 14 09:25:00 then the stuff you linked should work Jul 14 09:25:11 Oh superb, how might I go about this joyful task? Jul 14 09:25:14 Willdude123: do you get any error message when setting this? Jul 14 09:25:26 Willdude123: do you have an oscilloscope? Jul 14 09:25:32 Nope, and nope. Jul 14 09:25:54 hmm... Jul 14 09:26:15 what do you use to test your baudrate? Jul 14 09:27:07 My ears. Jul 14 09:27:19 ok, what do you hear? Jul 14 09:27:32 Well, or I can use the decoding software to try and decode it/ Jul 14 09:27:38 Wait, I had a sound file. Jul 14 09:28:00 no need to Jul 14 09:28:05 i dont have time to listen to it Jul 14 09:28:14 just tell me what you hear and what you think goes wrong Jul 14 09:28:19 https://dl.dropboxusercontent.com/u/9477294/rtty.wav Jul 14 09:28:38 I hear it as something probably around 900 baud but I may be wrong. Jul 14 09:28:47 I'm not really sure/ Jul 14 09:29:27 hmm.. Jul 14 09:29:34 so it's rather high Jul 14 09:29:54 check the TRM whether the bbb can actually do that low baudrate with the clock settings Jul 14 09:30:01 TRM? Jul 14 09:30:11 technical reference manual of the processor Jul 14 09:30:17 to be found on ti.com Jul 14 09:30:52 if it is possible, check whether the kernel does these settings correctly at these low baud rates Jul 14 09:31:18 No clue how to. Jul 14 09:31:42 step one, read the serial interface section in the TRM :) Jul 14 09:33:09 _SY_: dont p message me, ask in the channel Jul 14 09:42:53 <_SY_> Trying to figure out why when I add an entry to fstab it prevents my bbb from booting. Jul 14 09:44:41 what's the error message? Jul 14 09:45:16 <_SY_> Where would I find the error message in the journal ? Jul 14 09:45:41 * KotH has no idea how systemd works Jul 14 09:46:26 systemd works? Jul 14 09:46:33 well, there should be an error on serial when booting Jul 14 09:46:49 no matter if lennartd is involved or not Jul 14 09:47:03 KotH: It's over 4k pages long! Jul 14 09:47:04 <_SY_> Not as far as I can see, it takes forever to boot on serial and when it does there is no network Jul 14 09:47:30 Willdude123: and your point being? Jul 14 09:47:37 Nothing. Jul 14 09:47:44 Just a bit surprised. Jul 14 09:48:06 processor documentations have to be complete, otherwise you are fucked as soon as you want to do some real stuff Jul 14 09:48:10 you dont have to read all of it Jul 14 09:48:19 just the one or two sections you really need Jul 14 09:49:08 I'm control f-ing serial-interface. Jul 14 09:49:13 Willdude123: so? Jul 14 09:49:33 Willdude123: I don't expect people in this channel to have the TRM memorized just to answer some questions :) Jul 14 09:49:33 Hmm. I can no longer ssh to my bbb. Jul 14 09:49:35 Willdude123: you have a TOC Jul 14 09:49:47 Weird. Jul 14 09:50:05 Right Jul 14 09:50:07 <_SY_> From the serial boot: http://pastebin.com/74M638in Jul 14 09:51:15 <_SY_> Then http://pastebin.com/HL7CexUg Jul 14 09:51:43 Huh? Jul 14 09:52:18 <_SY_> This isn't for you Willdude123, relative to my problem Jul 14 09:52:50 <_SY_> lewis1802 Jul 14 09:53:02 Gerald is just being obtuse Jul 14 09:53:37 "Baud rate from 300 bps up to 3.6864 Mbps" Jul 14 09:54:11 Well, I can manage 300 baud, but it's not ideal, and that didn't seem to work either. Jul 14 09:56:48 Will, bit bang it with the PRU Jul 14 09:56:53 woudl be perfect for this kind of task Jul 14 09:57:39 What's that? I could just write the serial/ rtty code myself. Jul 14 09:57:48 Ack Jul 14 09:57:50 Dammit. Jul 14 09:58:06 My BBB is plugged into my PC but isn't Jul 14 09:58:10 connecting Jul 14 09:58:11 the PRU is the Programmable Realtime unit Jul 14 09:58:19 that is part of the AM3559 Jul 14 09:58:30 its like having another processor Jul 14 09:58:34 Right. Jul 14 09:58:36 "sort of" Jul 14 09:58:53 So I can't do it on a serial port then? Jul 14 09:59:07 300 baud is Okayish Jul 14 09:59:09 it only goes down to 300 Jul 14 10:02:23 Yeah, but on the PRU, would I use a uart or a gpio pin? Jul 14 10:02:39 It doesn't seem to even be able to do 300 Jul 14 10:03:07 the PRU is used to toggle gpio pins with cycle exact timing Jul 14 10:03:07 <_SY_> g2g, will be back later. Jul 14 10:03:08 So why the hell is my bbb not connecting. Jul 14 10:03:14 Ah right. Jul 14 10:03:17 so you can generate aribtrary waveforms Jul 14 10:03:31 Arrgh Jul 14 10:03:40 Why is this not working. Jul 14 10:03:49 It won't actually connect. Jul 14 10:03:49 bad karma ;-) Jul 14 10:04:31 It just cut out earlier, of the vnc and ssh session. I rebooted it and it still isn't working. Jul 14 10:05:30 ffs Jul 14 10:05:56 Willdude123: The PRU is however complex to program. Jul 14 10:06:16 Oh yay Jul 14 10:06:21 Jesus Jul 14 10:06:33 This fucking thing isn't even connecting at all atm. Jul 14 10:06:36 [kernel] ZubairLK opened pull request #49: Add continuous sampling via /dev/iio to ADC (3.11...3.11) http://git.io/uwXx1Q Jul 14 10:06:50 How the fuck am I supposed to fix it with no ssh. Jul 14 10:07:14 I wonder if the DMA unit can be clocked at 50hz from somewhere, and then simply write a bit-pattern to a GPIO. Jul 14 10:07:40 Willdude123: Worst case - reflash, or replace the SD. First check it's all plugged in. Jul 14 10:07:52 Yup Jul 14 10:08:15 How exactly do I flash it when it won't connect. Jul 14 10:08:43 Ooh Jul 14 10:08:50 removed the sd and it's okay now. Jul 14 10:08:57 So how do I program the PRU? Jul 14 10:09:42 Wait. I should be able to do 300 baud. Jul 14 10:10:22 SpeedEvil, you can trigger DMA from the timers Jul 14 10:10:27 The PRU is basically a 32 bit microcontroller (well, two of) on the die. Jul 14 10:10:46 shoragan_: yes, but will it go as low as 50hz. Actually - it doesn't matter. Jul 14 10:11:13 SpeedEvil: It sounds really complex. Jul 14 10:11:44 Willdude123: You basically need to configure the port pins to be assigned to the PRU, then write code for the PRU , then get the PRU to take data given to it by the main CPU in a buffer, and serialise it out. Jul 14 10:11:52 It is. DMA may actually be rather simpler. Jul 14 10:12:17 Or just live with 300bps - it's quite usable for hab. Jul 14 10:13:00 SpeedEvil, it should, you have a 24MHz clock and and a 32bit counter Jul 14 10:15:15 Willdude123: what kind of transmitter/encoding do you use, that you need to go down to 50 baud? Jul 14 10:15:43 Willdude123: i'm quite sure that you should be able to work with 2400 in most cases. you have permanent line of sight to the baloon after all Jul 14 10:16:28 Willdude123: or is transmit power the problem? Jul 14 10:16:57 KotH: 10mW/433MHz/500km desired Jul 14 10:17:21 KotH: this works well with simple narrowband FSK on 50bps, with good receivers. Jul 14 10:17:36 And the transmitter being at 30km. Jul 14 10:17:42 SpeedEvil: the PRU is'tn that hard to use Jul 14 10:18:00 mrpackethead: Not for someone with experience, no. Jul 14 10:18:10 SpeedEvil: hmm... fsk with that low power... ok i see the prob Jul 14 10:18:12 mrpackethead: But it's at least several steps to get your head around. Jul 14 10:18:17 hold theres a good tutorial Jul 14 10:18:49 SpeedEvil: wouldn't using something like apsk32 be better in that case? Jul 14 10:19:22 http://blog.boxysean.com/2012/08/12/first-steps-with-the-beaglebone-pru/ Jul 14 10:20:01 KotH: In principle, yes, to a degree, but not really. Jul 14 10:20:10 why? Jul 14 10:20:37 KotH: The transmitters are basically FM transmitters, which are being used to make narrowband FM signals. Making a phase shifted signal with any semblance of reliability is tricky. Jul 14 10:20:59 SpeedEvil: ah.. using cc1100 and the like? Jul 14 10:21:20 well, yes, you would need more complex custom electronics in that case Jul 14 10:21:55 SNR at 50bps is not an issue - it is clearly above the noise, in a good receiving environment. No - RFM22 transmitter modules are typical Jul 14 10:21:57 http://ava.upuaut.net/ Jul 14 10:23:22 I thought the NTX2 is more popular SpeedEvil Jul 14 10:24:08 KotH: We do need to go down to 50 baud usually, as less antenna gain is needed for decodes. Jul 14 10:24:36 SpeedEvil: I'm not sure it will even work at 300bps Jul 14 10:25:26 It works fine up to about - IIRC - 9600 Jul 14 10:26:00 You do need to widen the seperation, and the SNR in the recieved band is smaller, and most of the common radios won't work for it. Jul 14 10:26:20 What rtty? Jul 14 10:26:24 Really> Jul 14 10:26:45 But I'm not sure pyserial can do 300bps accurately. Jul 14 10:27:21 It's not really RTTY - but ascii - and yes - FSK with those modules can go really quite fast. Jul 14 10:27:41 They're not designed to be received at 500km! Jul 14 10:28:04 The TRM says they can go up to 3mbps. Jul 14 10:28:14 SpeedEvil: any good introductory talks on high altitude baloons to listen to? Jul 14 10:28:27 hmm. Jul 14 10:28:33 KotH: Well. Jul 14 10:28:39 that stuff looks interesting :) Jul 14 10:28:41 Last year there was a conf. Jul 14 10:28:48 I don't know about talks - #highaltitude is active. Jul 14 10:28:50 I think there are some vids. Jul 14 10:28:54 Are you in the UK? Jul 14 10:29:17 You could come along. I can't go because I'm only 13 and my parents won't let me. Jul 14 10:29:22 http://ukhas.org.uk/ is probably a sane one. Jul 14 10:29:41 * KotH is chocolate land based Jul 14 10:30:24 JN47 Jul 14 10:32:14 Can I get the BBB to run this at startup? x11vnc -bg -o %HOME/.x11vnc.log.%VNCDISPLAY -auth /var/run/gdm/auth-for-gdm*/database -display :0 -forever Jul 14 10:34:32 Ah got it. Jul 14 10:34:52 what i would really like to do is, to get one of the rockets http://www.spl.ch/ is building and send something up there :) Jul 14 10:41:20 KotH: spacex.com - they even have prices. Jul 14 10:41:59 where is the fun in that? :) Jul 14 10:42:12 i'd like to build the damn thing myself! :-) Jul 14 10:43:36 * ogra_ hands KotH http://www.copenhagensuborbitals.com/ Jul 14 10:45:36 :-) Jul 14 10:50:31 so how did all of you people start learning beaglebone and its software programming Jul 14 10:50:52 * KotH didnt Jul 14 10:52:08 currently i know arduino, is it possible to use the I/O pins like in arduino? Jul 14 10:52:29 ACTION  Jul 14 10:52:39 * drakeeeeeeeeeeee 'says hi' Jul 14 10:52:48 * drakeeeeeeeeeeee says help Jul 14 10:53:21 yes Jul 14 10:53:24 and no Jul 14 10:53:35 Hmm, I change Uenv.txt, but UART4 still isn't starting up Jul 14 10:53:36 yes, you can use gpio, no, the access is not as direct as on arduino Jul 14 10:53:48 *changed Jul 14 10:54:15 so for linux, what programming do you use Jul 14 10:54:48 what do you mean by "programming" ? Jul 14 10:55:00 the langugage? the environment? Jul 14 10:55:14 ya, language Jul 14 10:55:27 Is there a type of IDE Jul 14 10:55:39 linux is c Jul 14 10:55:43 ;) Jul 14 10:55:52 linux is not c Jul 14 10:56:00 So with C how do you use the gpio pins? Jul 14 10:56:04 the kernel is written in c, the OS is written in a whole bunch of languages Jul 14 10:56:17 linux IS the kernel Jul 14 10:56:19 drakeeeeeeeeeeee: there are tons of tutorials that deal with that Jul 14 10:56:23 are there tutorials? where di all you guys learn how to use beagle board for projects? Jul 14 10:56:42 drakeeeeeeeeeeee: using bbb is the same as using any other embedded linux system Jul 14 10:56:54 ok thanks, ill get starting using bbb Jul 14 10:56:57 thanks Jul 14 10:57:11 * drakeeeeeeeeeeee says thanks Jul 14 10:57:51 Is there anyways to use ubuntu desktop with the full GUI on the BBB? Jul 14 10:57:57 and actually one can use the gpiolib sysfs interface to control gpios without any programming. Jul 14 11:00:56 I'm having a hell of a lot of trouble decoding this. Jul 14 11:10:42 pb__, sure, if you manage to get an xserver with composite going and dont care about running anything else but the desktop (the ubuntu desktop alone uses up about 400M, you wont be able to start many apps before it starts swapping) Jul 14 11:26:38 Any experience with samba/swat Jul 14 11:39:11 bleh, cant seem to get xinetd to start swat correctly. Jul 14 11:43:36 hi Jul 14 12:14:24 Hi Jul 14 12:15:22 How do I use vnc and ssh without a cable? Jul 14 12:16:14 <_SY_> hi Jul 14 12:16:39 <_SY_> what sort of cable? I only use ssh with Putty and RJ45 ethernet cable Jul 14 12:17:03 Well. Jul 14 12:17:07 I mean on the bbb Jul 14 12:17:10 <_SY_> me2 Jul 14 12:17:17 I have wifi Jul 14 12:17:27 So I shouldn't need the usb cable. Jul 14 12:17:31 <_SY_> shouldn't be any different, still ethernet Jul 14 12:17:40 <_SY_> I only use the USB cable for power... Jul 14 12:17:50 So is it still going to have the same ip? Jul 14 12:18:00 <_SY_> Does your BBB appear in your routers attached devices listing? Jul 14 12:18:05 Once it disconnects from usb Jul 14 12:18:11 Not sure. Jul 14 12:18:19 <_SY_> Ok, log into your router and check. Jul 14 12:18:59 <_SY_> If it doesn't appear in your router then you won't be able to connect to it. Jul 14 12:46:01 I am unable to check if it comes up- there is no list. Jul 14 12:49:17 How do I make my BBB allow ssh without it being plugged in on usb? Jul 14 13:23:04 Device tree pros - lend me your ears! How do I get an interrupt working from a GPIO pin on the new BBB using DT? Jul 14 13:48:06 wow.. hard float debian runs really nice on the bbb Jul 14 14:07:54 [A Jul 14 14:08:00 oops sorry Jul 14 14:10:45 tomcat on the bbb... nice Jul 14 14:16:24 How do I make my BBB allow ssh without it being plugged in on usb? Jul 14 14:17:50 <_SY_> If you are asking how you get it to work over wireless, then have you validated that the BBB appears in the router as attached? Jul 14 14:17:51 Willdude123: why do you think its not? Jul 14 14:19:04 hi, i am looking to buy a Beagle.B' and wonder does the documentation cover the schematics(layout) of the product ? Jul 14 14:19:31 <_SY_> Yes, and you can download the PDF to review yourself now. Jul 14 14:20:24 _SY, thanks Jul 14 14:20:48 <_SY_> np :) Jul 14 14:21:01 * Tenkawa is very happy with his bbb Jul 14 14:22:36 _SY_: Yep Jul 14 14:22:54 <_SY_> ok, what ssh client are you using? Jul 14 14:23:12 Tenkawa: When I go to the ip I normally connect to, after it's unplugged, it times out. Jul 14 14:23:16 PuTTY Jul 14 14:23:38 But it is the fact I can't reach it on 192.168.1.7 not the ssh specifically. Jul 14 14:23:50 <_SY_> ok, I didn't have to do anything special to get it to work, have you validated that you can connect with the BBB with a wired ethernet connection first? Jul 14 14:24:01 Willdude123: is that ip the real nic? Jul 14 14:24:08 <_SY_> I mean an ethernet cable plugged into the RJ45 socket, not USB. Jul 14 14:24:10 Willdude123: ie the rj45 port Jul 14 14:24:27 _SY_: exactly :) Jul 14 14:24:39 No, I can't get ethernet up here. Jul 14 14:24:50 <_SY_> where is your router? Jul 14 14:24:51 Willdude123: huh??? Jul 14 14:25:10 oh he's probably using hpna... Jul 14 14:25:11 I have no unused ethernet connections here. Jul 14 14:25:19 ugggh i hope not Jul 14 14:25:30 Well, cables. Jul 14 14:25:40 IDK Jul 14 14:25:49 Why won't it work over wifi though? Jul 14 14:25:52 It's connected. Jul 14 14:25:55 it will Jul 14 14:26:07 you are using the wifi ip right? Jul 14 14:26:20 Is it still on 192.168.1.7? Jul 14 14:26:24 no Jul 14 14:26:38 its whatever the wifi device is Jul 14 14:26:43 is there a way to add conditional USB boot to uenv.txt? Jul 14 14:27:02 as in, if pendrive is connected, boot from there, otherwise boot from emmc? Jul 14 14:27:04 <_SY_> ok, connect to your router, login and get the IP address that your router has assigned to your BBB. Then use that IP in putty Jul 14 14:27:06 how are you wifi attached to the bbb? Jul 14 14:27:09 How do I find out the bb's IP? Jul 14 14:27:12 USB wifi. Jul 14 14:27:17 kfoltman: i wish Jul 14 14:27:34 kfoltman: although from my experiments/attempts no Jul 14 14:27:57 Tenkawa: obvious attempts like "boot from usb, boot from emmc" don't work I presume? Jul 14 14:28:01 <_SY_> Your router will have an "Attached Devices" section, it will be listed there....if it isn't then you won't be able to connect to the BBB.... Jul 14 14:28:20 or "read emmc, read usb, boot" Jul 14 14:28:34 <_SY_> However....if your router uses WiFi security, then you will need to set this up on your BBB before it will be able to connect to the router. Jul 14 14:28:46 kfoltman: no..i think theres no boot code in the mlo/uboot/kernel to read the usb at boot Jul 14 14:28:55 dont quote me though Jul 14 14:29:01 Tenkawa: sure, but you can modify uenv.txt in emmc Jul 14 14:29:07 _SY_: It's got it's mac. Jul 14 14:29:10 Not it's ip Jul 14 14:29:13 kfoltman: yeah.. tried that Jul 14 14:29:23 _SY_: That's all set up Jul 14 14:29:25 kfoltman: it doesnt see sda Jul 14 14:29:34 only the mmc devs Jul 14 14:29:43 <_SY_> The MAC address is unique to the device, but if its connected to the router then the IP should also be displayed there. Jul 14 14:29:45 Tenkawa: screw sda, I think you need to use uboot-style device designations Jul 14 14:29:57 Tenkawa: I'll try and see if I get anywhere Jul 14 14:30:00 i think the dtb and firmware needs additions Jul 14 14:30:02 Tenkawa: I've booted from usb before Jul 14 14:30:07 AFAIK Jul 14 14:30:11 kfoltman: if you do please memoserv msg me.. Jul 14 14:30:25 Tenkawa: or your grandchildren... Jul 14 14:30:28 ;) Jul 14 14:30:30 i'd really like to try hooking up my ssd Jul 14 14:30:55 i was very sleepy when i tried so who knows Jul 14 14:31:05 good luck too Jul 14 14:31:13 _SY_: It's not there for any other devices either. Jul 14 14:31:28 <_SY_> What brand is your router? Jul 14 14:31:37 I guess one could nmap for local devices Jul 14 14:31:41 _SY_: heres an easier way for him Jul 14 14:31:58 Willdude123: if you run /sbin/ifconfig -a on your bbb Jul 14 14:32:02 <_SY_> Does the router have DHCP server enabled? Jul 14 14:32:08 do you get any wlan entries Jul 14 14:32:25 _SY_: lets see if he even has an ip assigned Jul 14 14:32:32 Yeah Jul 14 14:32:51 whats wlan0 address listed as Jul 14 14:33:07 inet addr:192.168.1.18 Jul 14 14:33:16 thats what you need to ssh to Jul 14 14:33:20 <_SY_> can you ping that IP from your PC ? Jul 14 14:33:27 not .7 Jul 14 14:33:58 Ah i've got it. Jul 14 14:34:06 cool :) Jul 14 14:34:06 That's it. Jul 14 14:34:10 congrats Jul 14 14:34:51 I think this should work. Jul 14 14:35:13 <_SY_> Now...can anyone help me with my fstat problem? Not getting anywhere fast with it. Jul 14 14:35:21 _SY_: whats up? Jul 14 14:35:53 <_SY_> Summary: If I add an fstat entry for my USB memory stick, the BBB won't boot, unless I use FTDI cable...but then I get no network...without the fstat entry everything is ok. Jul 14 14:36:10 fstat or fstab? Jul 14 14:36:36 <_SY_> Sorry, fstab, :) been a long day Jul 14 14:36:42 i hear ya Jul 14 14:36:51 <_SY_> The entry I'm using is " Jul 14 14:36:51 <_SY_> /dev/sda1 /mnt/usbstick auto rw,defaults 0 0 Jul 14 14:36:52 <_SY_> " Jul 14 14:36:54 i've been up since 2am on 4 hours sleep Jul 14 14:37:18 _SY_: i think its the init handoff Jul 14 14:37:20 <_SY_> woke up early with bad headache.... Jul 14 14:37:43 same thing i was running into trying to mount a usb root with a mmc/internal boot Jul 14 14:37:56 <_SY_> before I got my FTDI cable, I had this working fine, but for some reason I can't get back to that state. Jul 14 14:38:28 i'm going to probably experiment more later today.. got t run for now.. need caffeine bad.. Jul 14 14:38:31 <_SY_> I wonder if its an issue in an update to the firmware, because I'm sure it use to work Jul 14 14:38:41 Willdude123: did you get logged in? Jul 14 14:38:48 yeah Jul 14 14:38:49 _SY_: entirely possible Jul 14 14:38:52 Willdude123: cool Jul 14 14:39:02 bbl all ... afk Jul 14 14:39:32 <_SY_> ok, I'll be online later, have fun Jul 14 14:46:20 I understand all 4 LED's will be lit when done imaging but is there a way to verify activation of the imaging Jul 14 15:02:43 Hello, I'm trying to use the PRU with gpio mode inputs i.e. mode 7, _not_ PRU GPI mode (I require capturing input at speeds of about 10MHz and not 200MHz, and the pins I want to use don't have PRU GPI capability). However, I cannot seem to get the dtbo fragment file right. When I do echo $PINS, I do see the pins configured as inputs (0x2f, i.e. input mode, pullup/pulldown disabled), but I cannot Jul 14 15:02:43 read them from the PRU using GPIO_DATAIN. However, as soon as I type "echo xx > /sys/class/gpio/export" then I can successfully read the input from the PRU! So, this would be a workaround instead of using the dtbo fragment, but for one major problem. I'm guessing that when I use "echo xx > /sys/class/gpio/export" then interrupts or something are being enabled for the pins. Because reading from Jul 14 15:02:43 the PRU seems really slow - less than 1MHz or so speed, instead of the tens of MHz speed I expected. Anyone have an example dtbo file that can be used for reading mode 7 inputs via the PRU without interrupts? My dtbo fragment is here: http://pastebin.com/D1fdvAdM and you can see that I'm setting lots of GPIO pins as inputs (0x2f) in fragment@0, and fragment@1 is ocp and fragment@2 is enabling Jul 14 15:02:43 the PRU. Any help would be appreciated. Been struggling with PRU input on-and-off for weeks now. Jul 14 15:03:55 PRU outputs on the other hand are fine, no problem in mode 7. Jul 14 15:19:48 Tenkawa: usb start; setenv mmcroot /dev/sda2 rw; setenv mmcrootfstype ext2 rootwait; run bootcmd Jul 14 15:25:12 Has anyone managed to use the PRU for input capture at 10MHz or higher with mode7 GPIO mode? (There are not enough GPI pins on the BBB, so I need to use GPIO mode set as inputs). I can't seem to get a higher rate that 1-2MHz. I suspect maybe interrupts are enabled or something, slowing things down. Jul 14 15:27:24 hola Jul 14 15:27:28 al guien me puede ayudar? Jul 14 15:29:16 como lehago para instalar el ADT en CCSv5? Jul 14 15:29:37 has anyone ever used the BBB for fingerprint identification? Jul 14 15:30:15 gjord: those scanners are usually usb, the problem could be if it comes with a x86 binary only blob... Jul 14 15:32:37 dm8tbr: that's my concern. I was hoping someone here had cross compiled libfprint or something Jul 14 15:33:22 gjord: all my scanners are inside think-pads, so can't test this...

(3.8...3.8) http://git.io/ZU8hdw Jul 14 16:32:46 <_SY_> hello Jul 14 16:45:37 I downloaded latest linux image and proceeded to decompress it and then used Win32Imager to image a micro sd, then proceeded on inserting in the BBB and hold the boot button when trying to power on and the LED's aren't lighting up I'm not really sure where to go from here I tried imaging with both the eMMC and the original Jul 14 16:46:20 any help would be greatly appreciated Jul 14 16:46:32 <_SY_> What distribution? Jul 14 16:47:08 <_SY_> Angstrom, Ubuntu, Debian ? Jul 14 16:47:18 Angstrom Distribution (BeagleBone) 2013-06-20 Jul 14 16:48:11 <_SY_> ok, when u insert the SD card, the power was off? If not make sure it is, then whilst holding down the boot button, power up...wait until all four LED's have lit, then the flashing starts. Jul 14 16:49:13 <_SY_> Also, before you created the image, did you generate a checksum with the imager? Jul 14 16:49:30 no Jul 14 16:50:34 <_SY_> Might be worth doing that, I've always done that when creating images and its always worked for me Jul 14 16:51:33 I did select the MD5 checksum button Jul 14 16:51:39 * mru always uses a camera to create images Jul 14 16:52:23 <_SY_> :) Jul 14 16:53:33 so should I put the checksum on the microSD Jul 14 16:54:21 <_SY_> All I did was select the image, select the destination and check the checksum checkbox, thats it....what type of SD card is it, make ? Jul 14 16:54:40 its a PNY Jul 14 16:54:46 8gm Jul 14 16:54:49 8* Jul 14 16:55:02 8gb* Jul 14 16:55:35 the first time I tried it with the eMMC image 3 LED's stayed lit but never the forth Jul 14 16:55:45 <_SY_> I've had lots of SD cards that haven't been that reliable, some times they are fakes....I try to use SanDisk where possible. Jul 14 16:56:08 <_SY_> How are you powering the BBB ? USB or external supply? Jul 14 16:56:19 I have tried both ways Jul 14 16:56:53 I've read the direct 5V is the way to go when trying to boot off image Jul 14 16:57:33 <_SY_> yep, what current does your supply provide, I've heard it should be at least 1A. Jul 14 16:57:50 is it normal for the drive to be empty after being imaged Jul 14 16:58:33 <_SY_> I don't think so...let me check I have a microSD card with image on it. Jul 14 16:59:31 <_SY_> There should be files and two hidden folders on it. Jul 14 17:00:17 sorry I just missed that Jul 14 17:02:49 <_SY_> There should be files and two hidden folders on it. Jul 14 17:03:08 I had a feeling that wasn't right Jul 14 17:03:56 because after imaging and saying it's imaged it I can open the drive and it's blank Jul 14 17:04:19 do you think maybe another image Jul 14 17:04:40 <_SY_> could be the card reader or the card itself Jul 14 17:05:05 I have a suspicion it's the card reader Jul 14 17:05:22 <_SY_> I've had SD cards that I couldn't read on Windows, but could read on my MAC-book pro without problem. Jul 14 17:05:39 it's a Dynex I'm not too sure on their reliability Jul 14 17:07:04 <_SY_> I bought a cheap Fujifilm multi-card reader seems to work ok Jul 14 17:08:02 this one I just picked up for about $15 at bestbuy, I also have a super cheap one from ebayy coming Jul 14 17:08:07 ebay* Jul 14 17:08:26 <_SY_> mine was 7 GBP. Jul 14 17:09:17 can I boot from usb with BBB Jul 14 17:09:28 <_SY_> Is there anyone online that can tell me why I can't get my USB stick to auto mount using fstab ? Jul 14 17:09:43 <_SY_> Not sure... Jul 14 17:11:39 http://www.armhf.com/index.php/boards/beaglebone-black/ just found some more images to try Jul 14 17:13:03 <_SY_> I'd stick with Angstrom, I tried Debian and IMHO Angstrom has the best distribution for the BBB. Jul 14 17:15:19 I just read someone's post in a forum with similar problems with the 3 LED's when trying to boot and he switched to Raring and says it works great Jul 14 17:16:45 hopefully when the other USB adapter arrives I won't have this problem Jul 14 17:17:40 _SY_ : fstab has nothing to do with automounting Jul 14 17:18:10 _SY_ : and of course your question has nothing to do with the beagle, so you should look elsewhere for the answer Jul 14 17:19:16 <_SY_> Sorry, but according to what I've read /etc/fstab has everything to do with auto mounting, http://elinux.org/RPi_Adding_USB_Drives Jul 14 17:20:01 <_SY_> see bottom of the page on that link Jul 14 17:36:10 i love how hlpeful this place is sometimes. "that question isnt specifically about this product, go ask somewhere else" Jul 14 17:36:35 <_SY_> :) Jul 14 17:38:10 <_SY_> I'm pretty sure this wasn't a problem a short while ago as I've had to rebuild several times due to duff updates...and I think this is also due to an update, when I first got the BBB I had it configured to auto mount the USB stick in the exact manor I am trying now. Jul 14 17:40:54 about how long is it after I poer on with boot button held that all four LED's signal it's imaging Jul 14 17:41:12 power* Jul 14 17:41:13 <_SY_> at least 45 mins Jul 14 17:41:39 hi Jul 14 17:41:44 <_SY_> hello Jul 14 17:42:06 maybe you can help me Jul 14 17:42:28 <_SY_> whats up?

Jul 14 17:44:14 have you tried GatOne Jul 14 17:44:21 GateOne Jul 14 17:44:24 what is it? Jul 14 17:44:45 bursy, if its wired check your router for the IP address it was given then SSH into that Jul 14 17:44:59 a termianl for your BBB Jul 14 17:45:33 Dragon2: is it the same for beaglebone white? Jul 14 17:46:26 depending on your router its probably the highest numbered IP +2 Jul 14 17:47:11 not sure Jul 14 17:47:13 or, if you dont have access to the router tabels get a port knocker. itll find all the computers on the LAN Jul 14 17:47:41 if you have an android phone i recomend Fing Jul 14 17:47:42 i am only working with usb Jul 14 17:48:03 ooohhhhhhh Jul 14 17:48:08 thats cool which port knocker would you recommend Jul 14 17:48:59 before with angstrom there was the port /dev/ttyUSB0 that appeared so i use minicom Jul 14 17:49:06 for PC? theres tones of em, pick one and see how it works for you. i think Cain has a port knocking feature, but i havnt used it in a while Jul 14 17:49:47 usb should default to 192.168.2.7 but i dont know if you can ssh into that IP Jul 14 17:49:57 * flufmnstr never tried Jul 14 17:50:24 i am beginner in linux how do you do that?

Jul 14 18:11:19 i am linux noobie Jul 14 18:11:32 haha, we all had to start somewhere Jul 14 18:11:43 but i am not using a router just my computer Jul 14 18:12:15 you said you plugged it into the router Jul 14 18:12:39 oh, did you plug the BBW into the computer via an ethernet cable? Jul 14 18:12:46 yes Jul 14 18:12:57 ah. that wont work Jul 14 18:13:06 why? Jul 14 18:13:07 well, it would work, but it takes some configuring Jul 14 18:13:18 <_SY_> Someone posted something helpful in the forum :) Jul 14 18:13:25 SY you got any projects your working on Jul 14 18:13:28 configureing im not familliar with Jul 14 18:13:35 I cannot access to the router Jul 14 18:13:46 <_SY_> have removed quiet from uEnv.txt, now it tells me that its failing to mount the local file system on /mnt/usbstick Jul 14 18:13:54 <_SY_> Yes a few... Jul 14 18:14:12 the only thong i have to program th bbw is my computer Jul 14 18:14:19 <_SY_> I've written a Modbus TCP driver for the BBB which works really well. Jul 14 18:14:41 <_SY_> Also written a floating IP address manager that allows two BBB's to be clustered. Jul 14 18:15:11 bursy the easiest way to connect to it would be through a wired LAN connection Jul 14 18:15:14 thats awesome Jul 14 18:15:22 but you need access to a router to do that Jul 14 18:15:30 OR Jul 14 18:15:34 so they function as one? Jul 14 18:15:54 <_SY_> Yep, I have a working prototype of it...but needs tweating. Jul 14 18:15:58 <_SY_> *Tweaking Jul 14 18:15:59 configure your LAN port on the computer to be a router for the BBW so they're on the same network Jul 14 18:16:10 its linux, it is possible Jul 14 18:16:18 so can you add as many as you want to work as one? Jul 14 18:16:27 but i have no idea how to do it. google should know though Jul 14 18:16:49 <_SY_> I have configured mySQL to run on each in High Availability mode, so they replicate data to each other, then the outside world talks to the database using the floating IP, if one BBB fails the other takes over. Jul 14 18:17:35 Thats great Jul 14 18:17:50 bursy or if you have a serial to usb adaptor laying around you can tap ino the serial terminal Jul 14 18:18:03 so could you say its a mesh network Jul 14 18:18:19 i have a serial usb Jul 14 18:18:25 with all the same IP? Jul 14 18:19:11 <_SY_> Are you talking to me? Not sure what a mesh network is....but each BBB has its own unique IP address and a 3rd floating IP is used to allow communication to the cluster. Jul 14 18:19:13 I'm new to networking but am going to school for it starting in fall Jul 14 18:19:17 yes Jul 14 18:19:28 <_SY_> One of the BBB's is nominated the master of the cluster, if this fails the other takes over. Jul 14 18:19:33 oh i see Jul 14 18:19:43 its a little different then I thought Jul 14 18:20:01 <_SY_> The database's replicate between them so there should be almost 100% up time. Jul 14 18:20:24 flufmnstr: how does i plug the serial converter in the beaglebone? Jul 14 18:21:13 bursy oh good. look up connecting to the serial terminal pins on the BBW. you're gonna ahve to make some wire bridges from the pins to the adaptor Jul 14 18:21:26 a floating IP is very intreging to me Jul 14 18:21:43 unless you have some old 4 pin .01 plugs laying around Jul 14 18:22:29 _SY_ that sounds awesome. im setting up BBB to work as show controllers for a haunted house Jul 14 18:22:43 and i was planing on doing some sort of redundancy like that Jul 14 18:22:55 flufmnstr: ok i'll do that Jul 14 18:23:06 SY: does one of the beaglebones act as a master Jul 14 18:23:11 well not physical backups, but finding the missing machine and loading files for that controller Jul 14 18:24:09 bursy, once you have that all wired up you'll be good to go. just MAKE SURE your wireing is correct. nothing hurts more than frying the project you were jsut working on Jul 14 18:24:40 <_SY_> The BBB's are configured with mySQL to operate in Multi-Master Mode, my floating IP app, uses serial connections between the BBB's to exchange data...when the BBB using the Floating IP goes down, the other promotes itself to be the new master and takes on the Floating IP. Jul 14 18:25:17 _SY_ do you have code posted of that? Jul 14 18:25:36 that's great! Jul 14 18:26:20 <_SY_> I will upload it someplace once I'm happy with it....still a few minor tweaks I'd like to resolve....the main application is written in Java, with my own native library to manage the serial communications. Jul 14 18:26:44 sounds awesome, id love to take a look when its up Jul 14 18:27:25 <_SY_> The application itself is actually very simple...just getting the change over logic and condition correct that takes some thought, so you never end up with two devices using the same IP. Jul 14 18:28:28 <_SY_> I started out trying to use cronosync and heartbeat which are much larger clustering projects for linux, but after spending several weeks trying to get them to work on the BBB I decided to ditch them and write my own.... Jul 14 18:30:54 I would love to get the BBB's communicating through IFTTT Jul 14 18:32:40 my coding level is far from doing stuff like that myself. im still trying to figure out UART control :-\ Jul 14 18:33:10 <_SY_> Is there a minimal build of an Angstrom image available, just monitoring the startup of the default image and there is a ton of stuff in there, like sound card support etc... Jul 14 18:34:33 speaking of sound card support, anyone know off the top of their heads if the BBB can output multichannel audio? Jul 14 18:34:42 *digital Jul 14 18:34:56 **digital audio Jul 14 18:39:04 hmm, the TRM says it supports six i2s audio data pins Jul 14 18:39:14 that ought to be 12 channels then Jul 14 18:39:41 6 i2s?!?!?! i only saw the i2c ports. thats perfect. thanks Jul 14 18:40:06 * mranostay bikes out Jul 14 18:40:11 Hi guys, does the Angstrom have some LAMP configuration? If so, what are the versions? Jul 14 18:40:22 we have a room of gears that i wanted to fill with sound. 12 channels would make that amazing Jul 14 18:44:18 Has anyone had any experience with the image taking longer than 45 minutes to image Jul 14 18:45:09 <_SY_> yes Jul 14 18:45:32 <_SY_> hold on...mine seemed to take a long time, but it did finish. Jul 14 18:47:04 <_SY_> I want to re-initialise my usb stick for use as additional storage on the BBB, but can I find something to help? can anyone help? Jul 14 18:47:14 <_SY_> I know it involves using "dd" Jul 14 18:47:27 <_SY_> my device is /dev/sda Jul 14 18:47:37 I have a suspicion that it's functioning properly because I can't see the drive even though it's connected to my computer via micro usb but the CPU LED has been very active Jul 14 18:47:51 like re-partition it or reformat it? Jul 14 18:47:54 _SY_: dd if=yourimage of=/dev/sda ? Jul 14 18:48:08 oh, nm. got confised Jul 14 18:48:39 <_SY_> did this "dd if=/dev/zero of=/dev/sda bs=1k count=1" Jul 14 18:48:57 that clears the first two sectors Jul 14 18:49:08 what do you want to do ? Jul 14 18:49:19 <_SY_> how can I initialise all 32Gb of it with a filesystem ready for use? Jul 14 18:49:38 _SY_: read the manpage of dd and figure out what the parameters mean :) Jul 14 18:49:42 SY: yah it's been over 45 minutes now but the lights are still going should I just leave it alone for more time Jul 14 18:49:44 <_SY_> ok Jul 14 18:49:50 Could some of you paste me here outputs of the following commands (from terminal of Angstrom Distribution): "httpd -v", "php -v", "mysql -v" Jul 14 18:49:56 <_SY_> give it an hour Jul 14 18:50:05 Dragon2 if its still doing something id say leave it Jul 14 18:50:31 ok thanks Jul 14 18:51:46 <_SY_> My problem is patience...I don't want to be a master of linux and know it all...just want the stuff I'm dependant on to work so I can progress... :) so frustrating Jul 14 18:52:06 _SY_: dont worry, everyone had the same problem when they first started Jul 14 18:52:08 welcome o the club ;) Jul 14 18:52:13 well said Jul 14 18:52:14 *to Jul 14 18:53:04 <_SY_> Funny thing is I find learning stuff easier with books...I prefer paper, odd that... Jul 14 18:53:14 why is that odd? Jul 14 18:53:25 i hate hitting a wall and knowing its a simple little config variable or option switch but i have to find it Jul 14 18:53:41 <_SY_> because having used computers since I was 12 (1982) I would have thought the online method would be more natural Jul 14 18:53:41 which sometimes isnt easy Jul 14 18:53:42 nature of the beast Jul 14 18:53:56 _SY_: lol Jul 14 18:54:18 if you need to manipulate partitions under gnome just install gparted Jul 14 18:54:20 _SY_: i'm a lot younger than you are, and spend approx 5-10% of my salary on books :) Jul 14 18:54:32 flufmnstr: i'll be back. I think i found one of the proplem i have to reboot my computer Jul 14 18:54:50 rgr. ill be here....or around Jul 14 18:54:54 <_SY_> Yep, thats good to know, I'm rather proud of my technical library, can't put a price on it. Jul 14 18:55:25 _SY_: i can put a price on my library.... but i dont want to ^^; Jul 14 18:55:58 <_SY_> :)....books do seem to be getting cheaper...last book I bought "Node Up and Running" Jul 14 18:56:13 how was it? Jul 14 18:56:31 I know I get awesome networking books off ebay for a penny Jul 14 18:56:52 <_SY_> ok, but doesn't really go into enough detail, I wanted a book that also detailed how to write native librarys for Node. Jul 14 18:57:14 _SY_: most of the books i bought in the last year were older then i am... and some of those aint cheap :-( Jul 14 18:57:23 it always fascinates me how readily available and affordable knowledge is Jul 14 18:57:33 Dragon2: depends on the field Jul 14 18:57:48 ^^^^^^ Jul 14 18:57:52 Dragon2: try to find out how to build a low noise quartz crystal oscillator and you will bite on rock Jul 14 18:58:05 ok Jul 14 18:58:18 Dragon2: actually, anything beyond the four basic oscillator circuits is hard to find Jul 14 18:58:41 <_SY_> I have a little excercise I want to write in Node for a demo and self teaching... Jul 14 18:59:05 if you want to know about soduim isotopes theres a $9,000 book i can recommend. Jul 14 18:59:28 same goes for example for atomic clocks. the best book on that topic has been written in the 70s, is out of print, and copies cost 800chf up, if you can find any at all (last time i found one, it was from moscow) Jul 14 18:59:35 i just wiki'd it that's interesting Jul 14 18:59:52 flufmnstr: only on sodium isotopes?? Jul 14 19:00:02 yah I'm still at ground 0 with computer literacy Jul 14 19:00:07 flufmnstr: what kind of data does that book contain to justify such a price? Jul 14 19:00:11 all sodium isotopes. Jul 14 19:00:15 <_SY_> g2g, got some stuff to rubbish to burn...will be back tomorrow, have fun. Jul 14 19:00:33 take care SY thanks for your help Jul 14 19:00:52 <_SY_> np, enjoyed it. Jul 14 19:01:13 oh, nope. im wrong Jul 14 19:01:16 it was Silicon-29 Jul 14 19:01:31 https://www.youtube.com/watch?v=Lr93OsOopvo Jul 14 19:02:30 flufmnstr: according to my chemistry book, there are 20 sodium isotopes, of which only one is stable. all other have halflife times in the seconds to minutes range Jul 14 19:02:57 i was wrong i was silicon-29 Jul 14 19:03:01 *it Jul 14 19:03:23 ah.. Jul 14 19:03:23 ok Jul 14 19:03:32 that's a far more interesting topic :) Jul 14 19:03:47 i posted a periodictable video on it above Jul 14 19:04:08 well, on the book. not so much the element Jul 14 19:04:25 back Jul 14 19:04:40 flufmnstr: 26 isotopes, with 4 stable ones Jul 14 19:04:48 flufmnstr: still.. what data justifies 9kusd? Jul 14 19:07:20 cool vid fluff that's interesting Jul 14 19:07:28 yeah.. Jul 14 19:07:32 still.. 9kusd? Jul 14 19:08:03 Bathtub for elderly people - Qualitative best list No.9kusd Jul 14 19:08:13 lol Jul 14 19:08:29 google is really dumb Jul 14 19:08:37 i must ask my uni lib to get a copy of that book Jul 14 19:09:30 It has some great reviews - > http://www.amazon.com/dp/354045277X Jul 14 19:09:42 finally found the problem Jul 14 19:10:03 fluff: the lights are STILL flashing Jul 14 19:10:51 flufmnstr: it's working now . I found the problem Jul 14 19:11:14 sweet. what was the problem? Jul 14 19:11:54 my computer did not recognize USB device Jul 14 19:12:03 just powerred them up Jul 14 19:12:21 Dragon2 :-( Jul 14 19:12:22 I'm trying to image the BBB and LED lights are still active after an hour Jul 14 19:12:48 not sure where to go from here Jul 14 19:13:09 hit it with a hammer Jul 14 19:13:17 clearly there is a stuck electron Jul 14 19:13:19 I unplugged power and the lights are still getting powered from micro usb Jul 14 19:13:22 you must shake it loose Jul 14 19:13:27 lol Jul 14 19:13:50 will it help if I smash my face into the BBB Jul 14 19:13:59 oh. try with it using a single power source Jul 14 19:14:06 * flufmnstr is not a BB expert Jul 14 19:14:17 I did unfortunatly Jul 14 19:14:21 * KotH is not an expert in anything Jul 14 19:14:41 but i like to talk to people :) Jul 14 19:14:46 lol Jul 14 19:15:31 Dragon2 so wait, you had 2 cables plugged into it or jsut one? Jul 14 19:15:45 But now a othe problem : what are the default user:pwd on debian. Because they gave me one after installing the new image but it doesn't work Jul 14 19:16:15 u: root p: blank i think Jul 14 19:16:31 I had just the power from 5V adapter Jul 14 19:17:04 what was that 'still getti power over usb' bit? Jul 14 19:18:20 flufmnstr: not working, after installing it gave me u: debian p: temppwd but not working also Jul 14 19:18:39 well the image is on the microSD now thankfully Jul 14 19:18:55 the three files that are suppose to be there Jul 14 19:19:29 I dunno I guess I'm just going to try again and wait longer :( Jul 14 19:19:34 flufmnstr: i found Jul 14 19:19:45 flufmnstr: it was root root Jul 14 19:19:52 ahh Jul 14 19:20:07 i was just gonna say try combinations of root toor and admin Jul 14 19:20:36 Dragon2 sucks bro :-( Jul 14 19:21:06 have either the usb or the 5v, not both Jul 14 19:21:21 again im not an expert, but thats what id try Jul 14 19:22:26 just started imaging again while holding the boot i was able to see all the LED's activate Jul 14 19:22:47 now its just the heartbeat and cpu and a lot of hope Jul 14 19:23:00 LED's I meant Jul 14 19:23:30 * flufmnstr crosses fingers Jul 14 19:35:44 flufmnstr: thank you for your help Jul 14 19:36:15 no problem, glad it sorking Jul 14 19:36:20 *working Jul 14 19:52:44 fluff: you still around Jul 14 19:57:17 yep. did it work? Jul 14 19:57:28 not sure yet Jul 14 19:57:50 I deleted the MLO file Jul 14 19:58:16 twhich I read will cause the BBB to boot off microSD Jul 14 20:13:09 fluf: what image did you use to falsh your BBB Jul 14 20:20:48 Dragon2 i followed this http://elinux.org/BeagleBoardDebian#eMMC:_BeagleBone_Black Jul 14 20:21:10 thank you I will look into it right now Jul 14 20:22:41 wow Jul 14 20:22:52 that says 5 to 6 minutes Jul 14 20:25:15 fluf will I be able to cut and copy into Cloud9 to run it Jul 14 20:25:46 i dunno. i havnt used Could9 Jul 14 20:29:14 unfortunately it;s not even powering on now Jul 14 20:30:18 !?! Jul 14 20:30:22 that doesnt sound good Jul 14 20:30:37 if none of the lights are comming on does that mean jump out my window Jul 14 20:30:43 jk Jul 14 20:31:03 yes. Jul 14 20:31:04 lol Jul 14 20:31:08 I can here it trying to connect its almost like theres a loose connection or something Jul 14 20:32:50 strange without the micro sd in it I can't power it on Jul 14 20:33:08 I believe that's from the MLO file I deleted Jul 14 20:39:15 can anyone recommend a small image to image my BBB with Jul 14 20:43:13 <_SY_> I'm happy to say my USB / fstab problem now appears to be resolved. Jul 14 20:43:51 <_SY_> I think my USB stick file system was corrupt, because having re-initialise it, deleting and re-creating the partition, it now works. Jul 14 20:46:34 awesome Jul 14 20:47:00 I did find some stuff on partitioning microSD's Jul 14 20:47:13 now I got a real problem though Jul 14 20:48:14 <_SY_> whats the problem? Jul 14 20:48:16 I deleted my MLO file so that it would force the microsd to boot Jul 14 20:49:03 unfortunately when I thought it was imaging it wasn't and now my computer doesn't even recognize it Jul 14 20:49:32 I know because it's trying to boot from the microSD Jul 14 20:49:48 so should I just keep trying different images Jul 14 20:49:57 <_SY_> I found with SD and micro SD cards, that whilst my main dev. system wouldn't read them always, that my Mac-Book Pro would, so I use this to initialise them.. Jul 14 20:50:32 Hey. I know this is a lot to ask for but...I am eight reinstallations into a vm of Linux and three reflashes of a beagleboard (the reflashes were mostly because I tried to flash ubuntu...unsucessfully.) Putting that all aside, I'm trying to create a GUI for a program that will run on Angstrom on my BBB. I have the newest Beagleboard revision. I have downloaded what I believe is the correct toolchain, what version of QT Creator should Jul 14 20:52:08 Also a brief explanitory youtube may help with the configuration process if anybody knows one (already watched the Derek Molly videos) Jul 14 20:52:16 <_SY_> I found myself re-flashing BBB's due to various problems and not being able to see what went wrong, however got an FTDI cable and that is a real get out of jail free card, if you don't have one would seriously recommend getting one. Jul 14 20:53:15 <_SY_> This is the one I got...came within two days: http://www.amazon.co.uk/dp/B0055ELU46/ref=pe_385721_37038051_pe_217191_31005151_3p_M3T1_dp_1 Jul 14 20:54:21 I might be able to find one kickin around at work but if not I'll check that out, it might take a little longer to get across the pond though Jul 14 20:54:47 <_SY_> Should be able to get the same locally :) Jul 14 20:54:59 <_SY_> Just make sure its 3v. Jul 14 20:55:39 <_SY_> definately worth having, without it you are blind to the boot process. Jul 14 20:56:13 I know it's killing me to know what is going on Jul 14 20:56:36 http://www.armhf.com/index.php/boards/beaglebone-black/#raring this is what Im trying to image onto it Jul 14 20:58:07 Also, is there an IRC channel that pertains more to my situation or am I in the right place? (Not trying to be impatient, just want to make sure I'm in the right place :)! ) Jul 14 20:58:42 <_SY_> ok...not sure if its my own set-up but my BBB's aren't that quick to boot, seems to take forever until I can login with SSH. Jul 14 20:59:16 <_SY_> Your in the right place, but its the weekend and it seems to be quieter at the weekend. Jul 14 20:59:59 Ok :) That's perfectly fine. I'll wait my turn and make sure not to spam the group too often. Thanks for the response! Jul 14 21:00:57 elibman: check out this site http://learn.adafruit.com/beaglebone-black-installing-operating-systems/flashing-the-beaglebone-black Jul 14 21:01:05 <_SY_> np, normally, (weekdays) there are plenty of people in here. Jul 14 21:01:24 <_SY_> I'm off to bed now, early start tomorrow. Jul 14 21:01:31 night SY Jul 14 21:01:40 <_SY_> nite all :) Jul 14 21:05:46 Dragon2: thanks I got passed the flashing. Now just looking to crosscompile from a 32bit virtualbox of Ubuntu. I am mostly confused as to which QT Creator version I should install, and how to configure it to work with the toolchain Jul 14 21:07:26 I'm still stuck on flashing the BBB that was just the most informative page I found Jul 14 21:08:28 I deleted the MLO file from the BBB and now I only get the led's to light up when I have micro SD card in there Jul 14 21:08:53 I can't connect to the BBB and it's not showing up as a drive Jul 14 21:10:35 is there anyway to tell from the led's that the BBB is currently imaging? Jul 14 21:10:48 are they flashing? Jul 14 21:10:51 or are they all on solid? Jul 14 21:10:56 if flashing, it is flashing Jul 14 21:10:58 if its solid its done Jul 14 21:11:12 their flashing but they never turn solid Jul 14 21:11:25 this is probably the third time Jul 14 21:12:06 I have tried leaving it for an hour an half and they were still flashing Jul 14 21:12:44 Is it possible I messed it up due to improper imaging? Jul 14 21:32:15 If it's not flashing properly, I sorta found a way around this. Try installing the bbb.angstrom.ga image or whichever one it was that loads directly onto a microsd card. once that loads, you can SH Jul 14 21:32:21 shit it cut me off mid type Jul 14 21:33:33 you can sftp to the beaglebone's ip, send another copy of whatever distro you are using, and then copy that over to the eMMC using the dd command Jul 14 21:33:50 it worked for me after 8 hours of nonboots Jul 14 21:34:58 lol Jul 14 21:35:01 ok Jul 14 21:35:39 I think thats how i did it Jul 14 21:37:17 (you should be flashing the image to something like mmcblk1) Jul 14 21:37:23 I should just be able to download ubuntu off GateOne Jul 14 21:37:40 that is probably an easier suggestion lol Jul 14 21:37:46 kfoltman: thanks for the usb info Jul 14 21:38:09 I just unopened my new BBB.
