**** BEGIN LOGGING AT Mon Mar 23 02:59:59 2015 Mar 23 03:01:12 i need help please Mar 23 04:31:08 Hey everyone! I have a serial connection on P9_11 and a servo connected to P9_16. For some reason, when the servo is powering on, it makes the select() on the serial connection think there is data coming in. Mar 23 04:31:32 Has anyone heard of this? Mar 23 05:12:21 Actually, I think it is because of a power drop when the servo turns on. :< I have a good source for power, but the draw on the servo messes with my serial connection. Any suggestions to help the start of the servo to not be so crazy? (besides another power supply, which I tested and works) Mar 23 05:13:07 a big fat cap near the servo? Mar 23 05:14:18 what kind of servo is this? Mar 23 05:14:40 Haha, that is what I was thinking. its a basic small servo from parallax Mar 23 05:14:52 as in RCservo? Mar 23 05:15:02 is this the continous rotation one? Mar 23 05:15:09 yea, exactly Mar 23 05:16:38 I have no problems with that exact servo Mar 23 05:16:48 but I am running it off a different supply Mar 23 05:16:58 you drawing 5V from the BB? Mar 23 05:17:35 what are you using to generate the PWM? Mar 23 05:19:45 yea, i have a 5v 3.1a adapter Mar 23 05:19:56 and drawing from the 5v from P9 Mar 23 05:20:18 do you have a mechanical load on the servo? Mar 23 05:20:29 Nope Mar 23 05:20:55 odd... I measured the draw from the servo and it was pretty low (<50mA) Mar 23 05:21:07 lol.......... I tihnk I realized my mistake Mar 23 05:21:15 I was on 5VDD instead of SYS5v Mar 23 05:21:18 this is in contrast to another one that pulled as much as 500mA Mar 23 05:21:27 5VDD is fine Mar 23 05:21:32 5VDD is direct to the power cube Mar 23 05:21:35 hmm, it doesn't do it on 5VDD Mar 23 05:21:39 or.. does Mar 23 05:21:42 I meant :) Mar 23 05:21:46 SYS5V goes through the PMIC's PFET Mar 23 05:21:49 sys 5V works fine Mar 23 05:21:56 drawing too much on SYS5V can kill things Mar 23 05:22:07 nvm, I lied Mar 23 05:22:15 It still happens after checking several times Mar 23 05:22:30 how are you doing your PWM? Mar 23 05:23:00 8: ff:P-O-L Override Board Name,00A0,Override Manuf,am33xx_pwm 9: ff:P-O-L Override Board Name,00A0,Override Manuf,bone_pwm_P9_16 Mar 23 05:23:06 in slots Mar 23 05:23:20 and then writing to the PWM via the run file Mar 23 05:25:11 I guess I could ask this: what would be the easiest or best way to do PWM with C/CPP? Mar 23 05:25:21 use the HW module Mar 23 05:25:53 are you buffering the PWM before it goes to the servo? Mar 23 05:27:21 Not 100% sure, I just saw a linux guide http://www.linux.com/learn/tutorials/776799-servo-control-from-the-beaglebone-black Mar 23 05:27:42 I just started trying to do PWM stuff today, I understand how PWM works, just not so well with embedded linux :) Mar 23 05:29:26 So, using the HW module - do you have a link or know of a good starting guide that I can refer to? Mar 23 05:29:37 I am personally not convinced not buffering it and running it at 3.3V is a sound engineering practice Mar 23 05:29:57 not really... I just did it all from "good engineering practice" Mar 23 05:30:12 I have it at 5V, but still, I am new to embedded linux so I am learning this still Mar 23 05:30:13 that module is rated for 5V so I gave it 5V and buffered/level shifted the PWM signal to 5V Mar 23 05:30:16 no no Mar 23 05:30:21 the BBB outputs are 3.3V Mar 23 05:30:40 BBB out as in the P9_16 line Mar 23 05:30:50 Ahhh, I see Mar 23 05:30:54 eventually I will write up something Mar 23 05:31:05 if you got a scope, slap it on there and see Mar 23 05:31:18 the levelshifting/buffering is a open collector driver Mar 23 05:31:34 I am still learning this stuff, so "Good engineering practices" is something that I still need to learn :P Mar 23 05:31:38 easy 2N2222 + resistor... the servo seems to do odd things under some conditions Mar 23 05:31:50 oops... bbl, got to take care of something Mar 23 05:32:08 Okay, I just had the resistor, but I can get the diode Mar 23 05:32:13 thanks Mar 23 05:35:56 so what is pwm used for in servos Mar 23 05:48:32 if you look at the specs, 3.3V is the lower margin Mar 23 05:48:55 putting a diode/transistor will put it below that which may put it into an undefined state that can draw too much power or other bad things Mar 23 06:00:51 I meant 2N2222, not the diode Mar 23 08:47:12 Hi fellas, i am trying to turn off the usb client by command. I found that this turn off the power off usb host "devmem2 0x47401c60 b 0x00" Mar 23 08:47:52 Someone knows what is the memory addres for do the same to usb client or where i can find it? Mar 23 08:49:14 don't screw with memory directly. The MUSB driver probably exposes this Mar 23 09:36:52 !ping jkridner Mar 23 09:48:39 gnif I think jkridner is at sleep at this time Mar 23 09:49:07 woglinde, thanks :), do you know what timezone he is in? Mar 23 09:50:37 us Mar 23 09:54:41 hello, I have mainline kernel 3.19 and I wonder how can I load a device tree overlay with this kernel Mar 23 09:54:48 it seems that device tree overlays were reintroduced with this kernel but I can't find any documentation how to use them Mar 23 09:55:20 and it seems that the whole device tree god modular and to "unlock" UARTS one have to use device tree overlays Mar 23 09:55:28 got* Mar 23 09:57:44 mh, not sure if that's a runtime thing. I didn't really look closely. Mar 23 09:58:00 could it be that overlays are right now boot time? Mar 23 09:58:37 maybe, but still I have to have some way to load them :) Mar 23 11:40:34 gk: http://events.linuxfoundation.org/sites/events/files/slides/dynamic-dt-elce14.pdf Mar 23 11:42:13 gk: http://beagleboard.org/blog/2014-08-27-device-tree-overlay-support-lands-upstream/ Mar 23 12:25:52 _av500_: Please approve my mentorship request on Melange Mar 23 12:25:58 yegorich: and? because all I can see is "requires some patch" or "capemgr in the works" but how can I use it right now? :) Mar 23 12:30:53 Abhishek_: done Mar 23 12:33:41 yegorich: another interesting thing is that the pdf says that the binary format wasn't changed but when I try to use device tree from 3.18 with 3.19 it doesn't even boot Mar 23 12:38:53 yegorich: fortunatelly it seems that I can get vanilla 3.18 to work now so at least I have some pretty new kernel that works Mar 23 13:13:43 gk: it was all info I could find. Have you tried to ask device tree overlay author directly? Mar 23 13:14:27 hello, Mar 23 13:14:27 I have a problem. Mar 23 13:14:27 my black BEAGLEBONE not boot on sd card. without sd card, only the pwr LED is on and nothing autre.je not find the procedure to restore as before. Mar 23 13:14:27 thank you Mar 23 13:17:39 sorry my BEAGLEBONE black starts only on sd card Mar 23 13:18:35 hi guys i was wondering if anyone has gotten a netgear a6100 working with their beaglebone black. I have been trying to find/compile drivers for it have been unsuccessful so far Mar 23 13:19:17 shinzuka, if you want to boot off the emmc, you can use one of the flasher images, or simply copy with DD like this dd if=mmcblk0 of=mmcblk1 You need to run fdisk to see which disc is which. Mar 23 13:20:06 are rcn-ee repos down right now? Mar 23 13:22:01 I can not launch anything and not memory access EMMC, only the sd card boot Mar 23 13:22:06 shinzuka: have you flashed the emmc? Mar 23 13:23:21 not flashed Mar 23 17:07:42 hi , someone used tslib ? Mar 23 19:20:46 hi all — i have a beaglebone black board, rev. C, and suddenly, yesterday, the ability to ssh into it at 192.168.7.2 stopped, i plugged it in, it wouldn't let me ssh in. i get 'ssh: connect to host 192.168.7.2 port 22: Connection timed out' - what is more, in a browser, if i type in http://192.168.7.2, it does not give me the standard beagle bone page it is supposed to deliver, just 'Error code: ERR_CONNECTION_TIMED_OUT' same is tr Mar 23 19:22:06 (cont'd.)... ide on the board with http://192.168.7.2:3000 - ERR_CONNECTION_TIMED_OUT. any help getting it back to where i can ssh in and see the web pages again? Mar 23 19:24:34 faddah .. are the LEDs still flashing .. do you have a debug cable to connect to to it to see any log messages? Mar 23 19:25:08 are you connecting via USB (which I think is a 'yes' by the IP address. .. ) have you tried with an ethernet cable plugged into your router/etc? Mar 23 19:26:25 veremit - yes, blue LEDs on board are flashing just the same as they ever were. i don't know what a debug cable is nor where to connect it — sorry, i am new to all this. yes, it is connected via USB. if i connect it to the router, how will i know what it's new IP address will be to ssh into it? Mar 23 19:27:19 faddah .. check your router's web page . usually has a 'clients' or 'dhcp' list Mar 23 19:27:49 and debug cables .. http://elinux.org/Beagleboard:BeagleBone_Black_Accessories#Serial_Debug_Cables Mar 23 19:27:59 I'd say a 'must' for any embedded work :) personally. Mar 23 19:30:13 veremit - so my only choice is to connect it to the router, i cannot connect it direct via usb any more? i have no idea what happened to make it stop ssh'ing or delivering the web pages at ip 192.168.7.2 over usb. Mar 23 19:30:44 veremit - also - yes, i have that debug cable, came with the kit, just didn't know it by that name. i was calling it a usb-to-pin cable. Mar 23 19:32:13 this also raises the question, how do you properly shutdown a BBB each time? is there a command you can send to it equivalent to shut down so it gracefully exits its OS and maybe this stuff doesn't happen? Mar 23 19:33:08 faddah .. you can send it a 'sudo halt' command to shut it down Mar 23 19:33:29 veremit - whilst ssh'd into it? Mar 23 19:33:40 there are many reasons the usb driver has gone south .. it could be your computer or the beagle .. but yeah, it shouldn't happen. Mar 23 19:33:56 faddah .. yes, it will 'kick you out' :) Mar 23 19:34:16 veremit - got it. gonna try connecting to the router. be back. Mar 23 19:34:18 you'll see the LEDs flicker and shut off Mar 23 19:34:32 veremit & all - thank you for helping thus far. Mar 23 19:34:55 faddah .. if it continues not to respond .. you can try flashing a uSD card .. and see if that works Mar 23 19:35:28 start with the "non-flasher" image to get it going, then you can re-flash the board if there's a real problem Mar 23 19:36:28 veremit - just got the board 5 days ago and really just starting with it now, so i have no idea how to flash anything. i'd have to go buy a new microSD card. Mar 23 19:36:58 cool .. lots to learn :) Mar 23 19:55:52 is 192.168.7.2 over usb a fixed ip or is it subject to change with reboots ? Mar 23 19:56:18 djlewis .. fixed IP iirc ..coded into the driver init Mar 23 19:56:44 you have disconnected the BBB and reconnected? Mar 23 19:56:57 so if you're unlucky enough to be using a class c network on 192.168.7.x and there is a PC on at 192.168.7.2 .. its not gonna work :) lol Mar 23 19:57:05 restarted wonders and all? Mar 23 19:57:24 djlewis - theoretically it Just Works(tm) Mar 23 19:57:45 veremit: just tossing out thoughts. I dont have a BBB Mar 23 19:59:47 http://www.linux-usb.org/gadget/ Mar 23 20:01:00 hi, is it possible to connect a hardware 3g/4g module to the beaglebone? Mar 23 20:01:13 iirc the beagle operates at least 3 'gadget' interfaces .. networking, mass-storage and terminal of some kind Mar 23 20:01:37 encircled .. over what interface .. the short answer is 'yes' .. :p Mar 23 20:02:34 3g/4g usb modems work in linux just like any other Mar 23 20:02:34 I was hoping to buy / add some kind of hardware board/module to a beagle bone for remote data collection / reporting - what are the options? Mar 23 20:02:57 gsm might require some additional hardware Mar 23 20:03:24 I see, over usb is fine, thanks veremit Mar 23 20:03:25 wifi is a natural choice Mar 23 20:03:33 back - sorry, got disconnected. Mar 23 20:03:41 wifi is not possible; remote location :) Mar 23 20:03:42 but then you need appropriate wifi adapter Mar 23 20:04:09 encircled .. you can use old-skool serial modem if you like Mar 23 20:04:36 i guess a usb modem is fine for my needs :) Mar 23 20:04:59 I have a 3g dongle connected via a linux nat arm board/router widget Mar 23 20:05:25 just need a sim card, data plan .. and off ya go Mar 23 20:07:16 a linux nat arm board/router widget ?? Can't you just plug a usb modem straight into the usb port? or will you need an external powered usb hub? Mar 23 20:08:09 encircled .. not sure what the power req's are .. but yeah, you can plug it straight in Mar 23 20:08:26 great, thanks! Mar 23 20:08:32 might need 'modeswitch' for usb possibly .. there are loads of howtos on 3g dongles in linux Mar 23 20:08:38 encircled: be carefull, most gsm modems use lots of power Mar 23 20:08:55 encircled: you might need a usb hub to provide that power Mar 23 20:09:06 yeah, I was thinking that might be the case :) Mar 23 20:09:11 encircled: the BBB is not that strong on delivering power from the usb port Mar 23 20:09:17 KotH .. is the beagle usb port restricted to 200mA ? Mar 23 20:09:23 no it isnt Mar 23 20:09:36 thought there was some power control on it .. but perhaps not Mar 23 20:09:53 but it is not good at handling this spiky power requirements that gsm modems have (not to say that a lot of those kind of violate the usb specs) Mar 23 20:10:57 must do some testing one day .. I'da thought the usb limit of 500mA constant ought to be sufficient .. Mar 23 20:11:12 but yeah .. the usb hubs we use recommend some good capacitance on the usb port sides Mar 23 20:11:19 well.. these modems are known to use up to 1.5A, short time Mar 23 20:11:21 chips_ Mar 23 20:11:33 it's still <500mA average, but short time it can be much more Mar 23 20:11:37 mm pulse requirement would kill any arm board Mar 23 20:12:03 no wonder wifi is a struggle :) Mar 23 20:12:11 uncoupling with 200-500uF ceramic capacitors usually helps Mar 23 20:12:12 thats why I prefer integrated chipsets :) Mar 23 20:12:29 veremit - i'm back. have beagle board black rev. C connected to router with ethernet cable and also plugged into power. trying to ssh into what i think is the IP Mar 23 20:12:31 yeah our hardware designs usually use 100/220 Mar 23 20:12:58 alu elec normally Mar 23 20:13:03 low impedance ofc Mar 23 20:13:31 veremit: i've never actually measured what the pulse times are, and how fast it rises Mar 23 20:13:52 veremit: the circuits i used this stuff in usually had very little space to spare, so we used ceramic caps Mar 23 20:13:55 KotH .. need a good current probe :) Mar 23 20:14:15 a goot oscilloscope is enough, you can measure the voltage drop :) Mar 23 20:14:17 KotH .. surprised you didn't use as much space on multiple caps as a small alu elec. Mar 23 20:14:29 can't get high cap MLCC chips Mar 23 20:14:37 you can get 100uF 6.3V in 1210 Mar 23 20:14:39 tants perhaps Mar 23 20:14:48 must be expensive :p Mar 23 20:14:57 lower profile and lower ESR than tantal Mar 23 20:15:05 true Mar 23 20:15:06 oh.. and they were cheaper than tantal back then Mar 23 20:15:30 we use panasonic 6x6mm caps though Mar 23 20:15:36 because some finnish company, known for its rubber boots thought it was a good idea to buy the world supply of tantal elcos Mar 23 20:15:56 (yes, that was some years ago) Mar 23 20:15:57 lol nice Mar 23 20:16:08 it wasnt nice Mar 23 20:16:30 I don't suppose that finnish company is doing so well these days? or am I thinking of another .. lol Mar 23 20:16:35 veremit - trying to ssh in - not working. i put in "$ ssh 192.168.1.3 -l root" [or .6, both are showing as connected on my network map without names], and it just sits there and eventually the connection times out. Mar 23 20:16:58 $supplier called us a month after our prototype run, saying that the cer caps we just bought have now a lead time of 25 weeks... because everyone switched to buy cer caps to replace the tantal caps that became unobtanium Mar 23 20:17:19 eek Mar 23 20:17:20 faddah .. I think you might need to break out that debug cable .. Mar 23 20:17:32 veremit: no, the company went back to rubber boots... no electronics anymore Mar 23 20:17:46 KotH .. well .. facny that lol Mar 23 20:18:07 but their production was a major PITA for a couple of years Mar 23 20:18:28 i have it, what do i do with it? are there troubleshooting instructions you can refer me to somewhere? there were troubleshooting instructions on the page that came up off of http://192.168.7.2/ on the board, but that is on the board and i can't get to it now. Mar 23 20:19:20 faddah: what did you do? connect your bbb over ethernet to the network? Mar 23 20:19:28 faddah: your dhcp server should know its ip then Mar 23 20:19:43 koth .. seems networking period or even the board is a bit south .. Mar 23 20:19:57 leds flashing but no ssh/etc Mar 23 20:19:58 faddah: have you connected a serial cable to the debug port? Mar 23 20:20:05 KotH yes, veremit advised me to connect to a router and try and ssh that way. Mar 23 20:20:08 which is where we're at :) Mar 23 20:20:17 ah.. Mar 23 20:20:25 serial cable and see what the debug port says Mar 23 20:21:16 something like https://codechief.wordpress.com/2013/11/11/beaglebone-black-serial-debug-connection/ faddah Mar 23 20:21:17 veremit - no - again, i don't mean to hammer you with beginner's troubleshooting steps, if there is a page somewhere on-line at beagleboard.org or something, i'll go look there. Mar 23 20:21:44 * KotH hands faddah a piece of chocolate Mar 23 20:21:51 faddah: thanks for being considerate! Mar 23 20:21:55 faddah: that's very rare here Mar 23 20:24:12 its a steep learning curve getting into arm boards .. but a rewarding one at the same time Mar 23 20:24:50 well i got hammered by someone in the forums on beagleboard.org for not "looking up" something before asking, i replied by saying i _did_ look it up, it just came back with incredibly old entries having to do with older beaglebone boards, not the black, and it was all for windows computers, not linux or a chromebook which is what i'm on. Mar 23 20:24:54 please send me your code and complete details :) Mar 23 20:25:48 faddah .. material is very fragmented and frequently out-of-date Mar 23 20:25:55 unfortunately Mar 23 20:26:04 djlewis: rotfl Mar 23 20:26:14 djlewis: it's "the codez" ;) Mar 23 20:26:24 KotH: yes, that was for U. :) Mar 23 20:26:35 djlewis: U? Mar 23 20:26:38 veremit - so i have found, all the more irk'ing to accuse me of not looking stuff up first, which i always try and do. Mar 23 20:27:09 you Mar 23 20:27:37 djlewis: ah.. Mar 23 20:27:47 djlewis: you should learn how to type english properly ;-> Mar 23 20:28:00 KotH: i knew you would appreciate the line Mar 23 20:28:08 having been around here for so long Mar 23 20:28:14 faddah .. it has been noted .. but tracking down all the sources is next-to-impossible. I have flagged it up as an issue to the likes of jkridner here, but its out of his control afaik. Mar 23 20:28:15 ^^; Mar 23 20:28:40 faddah: well, most people fail at knowing what google is Mar 23 20:28:46 elinux should be the go-to resource but there simply aren't enough 'good' contributors .. or anyone compiling from other sources. Mar 23 20:28:50 faddah: so the assumption that you havent looked it up is natural Mar 23 20:29:14 veremit: actually, i know a certain guy who just recently deleted a lot of entries from elinux, because they were crap Mar 23 20:29:51 KotH & veremit - i realize i am in a special situation here as my main computer here, for now, is a dev-mode Acer C720P Chromebook. Mar 23 20:30:05 faddah: uh.. my condolences Mar 23 20:30:16 KotH - ?? Mar 23 20:30:24 faddah: but get a serial2usb cable and conect it to your debug port on the bbb Mar 23 20:30:36 faddah: that's the only way to have halfway an idea what's going on on the bbb Mar 23 20:30:49 faddah: you have a very inconvenient development environment Mar 23 20:31:07 oh.. damn... it's the french guy! Mar 23 20:31:13 KotH & veremit - works for me, until i run into silly stuff like this. Mar 23 20:31:32 ssh and usb and basic networking are completely cross-platform as far as I'm aware .. Mar 23 20:31:36 faddah: everything around embedded systems is silly until you figure out what the problem is :) Mar 23 20:32:12 although to date, I haven't used MacOS .. or iOS .. *spit* Mar 23 20:32:23 faddah: it took me once 3 months to get spi working on a system... ended up using a frankenkernel stichted together from linux-next, and a ton of random patches from other sources Mar 23 20:32:39 KotH & veremit - anyway, those instructions you show have another smaller/daughter board in-between the debug cable with the four pin connections and the BBB. my debug cable came just with the usb connector on one end and the four pins out on the other, no smaller board. Mar 23 20:32:41 KotH .. if that's what it takes .. lol. Mar 23 20:32:53 faddah .. it'll be moulded in .. don't worry .. ploug on. Mar 23 20:32:59 faddah: you dont need any smaller board Mar 23 20:33:19 faddah: if the ends are 3.3V (which they most likely are, but check anyways), then you can just connect them to the debug port Mar 23 20:33:22 the elinux accessories site shows multiple types. Mar 23 20:33:31 veremit & KotH - well it's very confusing as those instructions keep mentioning that other board. Mar 23 20:33:37 if it came WITH the beagle .. you will be fine. Mar 23 20:33:49 veremit: yes... it took me almost 9 months to get that damn thing working... 3 weeks were planed Mar 23 20:34:07 KotH .. yea, my boss knows ALL about that kinda crap Mar 23 20:34:57 KotH .. and one of my colleagues is working through the same problem with a control protocol badly implemented by a third-party in order to satisfy a customer requirement .. Mar 23 20:35:05 veremit: $customer was happy anyways. we were the only ones that could deliver a system according to their specs :) Mar 23 20:35:17 KotH .. thats how we get paid ultimately. Mar 23 20:35:19 KotH & veremit - so i understand, take the BBB out from the ethernet cable into router, plug it back into the Chromebook again via USB, _then_ plug the debug cable into the debug port and into my 2nd usb port? is that what i am doing here? Mar 23 20:35:34 faddah .. that should work, yes Mar 23 20:35:59 faddah: does not matter how you power your BBB, but yes, serial2debug cable goes into computer Mar 23 20:36:11 .. or tablet, or phone .. etc. Mar 23 20:36:21 trying now. is there a url to a chart reference on-line as to the ports on the BBB so i know i'm plugging into the right debug port? Mar 23 20:36:37 there's one header besides P8 or P9 .. its marked Mar 23 20:36:37 the system reference manual has a description of the port Mar 23 20:37:25 faddah ,, I think you'll find image .. https://codechief.files.wordpress.com/2013/11/connector-3-jumper-wire-pins-1.jpg .. shows it fine Mar 23 20:37:29 can't beat graphics Mar 23 20:39:24 that tutorial I posted covers most of the ky points (ignoring the different debug adapter) Mar 23 20:39:38 hello, running debian wheezy on bbb and testin a ds18b20 sensor. followed this guide http://www.hobrasoft.cz/en/blog/bravenec/beaglebone-black-ds1820 ... Mar 23 20:40:00 but getting this error http://sprunge.us/cbaM Mar 23 20:40:23 weezelding: does it work anyway? Mar 23 20:40:30 ddrown: noup Mar 23 20:40:42 cannot find slave devices Mar 23 20:41:14 running Linux beagle 3.8.13-bone30 #1 SMP Thu Nov 14 02:59:07 UTC 2013 armv7l GNU/Linux to be specific Mar 23 20:42:04 weezelding: what error? Mar 23 20:42:24 KotH: second last line Mar 23 20:42:25 I can't see an error there .. Mar 23 20:42:39 there's some messages :) but are they relevant .. Mar 23 20:42:40 ah.. Mar 23 20:42:53 * KotH has never seen that one Mar 23 20:43:13 i would refere you to our DT specialist, but he is drinking beer at the moment Mar 23 20:43:19 [ 21.610475] of_get_named_gpio_flags: can't parse gpios property Mar 23 20:43:24 and will so for the rest of the week Mar 23 20:43:28 I got that message too, but it still worked Mar 23 20:43:30 : ) Mar 23 20:43:37 with a DS18B20 Mar 23 20:43:43 hmm Mar 23 20:43:59 weezelding: what you could do is check the documentation of how the gpios are to be defined in the kernel currently Mar 23 20:44:00 line before was different though: [ 21.610460] of_get_named_gpio_flags exited with status 45 Mar 23 20:44:10 weezelding: the DT specs changed a couple of times in the past Mar 23 20:44:34 KotH & veremit - sorry to be a bother, but i only have four pin wires coming off my debug cable - black, red, green, and white. none of that matches the pictures or instructions you have sent me. Mar 23 20:44:36 weezelding .. you could update to 3.8.13bone60+ Mar 23 20:44:55 faddah: you should have 3 wires: TX, RX, GND Mar 23 20:45:00 faddah .. do you have any documentation for the debug cable .. you need to find the 'GND' and 'TX' and 'RX' pins Mar 23 20:45:03 faddah: connect those accordingly to the BBB Mar 23 20:45:24 weezelding: this is the DTS I used for the DS18B20 - https://gist.github.com/anonymous/1293f98cca577751846c Mar 23 20:45:38 ddrown .. what kernel version have you got .. "uname -a" ? Mar 23 20:45:43 veremit: that's the plan actually. apparently it needs reflashing. did flashing half a year ago so my memory is futile, do i need SD card to do flashing? Mar 23 20:46:13 veremit: 3.8.13-bone70.5 at the moment Mar 23 20:46:14 weezelding .. lots of ways .. uSD is one .. or you can sftp a new image .. reconf... nope you can't probably cos its hard-written Mar 23 20:46:19 ddrown .. thanks Mar 23 20:46:44 weezelding .. do you have a /boot folder with a zImage/uImage .. vmlinuz in it? Mar 23 20:46:54 if not .. yes, uSD is the only way Mar 23 20:47:20 if you got a /boot with a vmlinux .. rcn has worked his magic :D Mar 23 20:47:21 veremit: yep, boot exist with zImage -> vmlinuz-3.8.13-bone30 Mar 23 20:47:57 cool .. you can cross-compile (or download, probably) a new version .. sftp it in, change the symlink, rsync modules and GO! Mar 23 20:48:09 sorry .. thats simplifying it a lot :D heh Mar 23 20:48:16 ( : Mar 23 20:48:31 if you understand that lot .. you're good to go, however :D Mar 23 20:48:34 it's over ten years since the last kernel compilation hehe Mar 23 20:48:54 weezelding .. guessing you didn't have a beagle back then .. or any arm boards lying around :) Mar 23 20:49:11 KotH & veremit - again, sorry for my nOOb questions, but there were no specific instructions that came with the kit tha show the pin connections for each of the four cable ends for the serial2debug cable. just a one sheet showing how to connect power to the BBB and the BBB to the computer via USB. Mar 23 20:49:17 veremit: true ( : Mar 23 20:49:36 ddrown: thanks Mar 23 20:49:43 veremit & KotH - it came from element14 Mar 23 20:49:53 ah, maybe i'll just flash it. quick'n'easy Mar 23 20:50:09 weezelding .. probably .. back up anything critical :D Mar 23 20:50:27 luckily i don't have anything critical there Mar 23 20:50:28 faddah: hmm.. they should have a datasheet somewhere Mar 23 20:51:08 was about to plug a 16x2 LCD screen but unfortunately that was 5V -> external power -> bummer Mar 23 20:51:12 KotH - nope, nothing. very limited kit. Mar 23 20:51:21 veremit: thanks for the hints Mar 23 20:51:26 faddah .. do you have alink to the kit online? Mar 23 20:51:34 weezelding .. np. Mar 23 20:51:41 KotH & veremit - hang on... Mar 23 20:54:07 crap, now i remember the memory card borked some time ago Mar 23 20:55:19 KotH & veremit - trying to look it up at the element14 web site and their site is as convoluted as i've seen. Mar 23 20:56:12 faddah ,.. sadly yes .. and I have to use their partner sites for business . . ! Mar 23 20:58:24 KotH & veremit - does the black go on the J1 jumper? Mar 23 20:59:57 debug looks like J1, yes Mar 23 21:01:06 faddah .. if you have a meter, you can check which is the 'Tx' pin at each end, because it will have a voltage on it unconnected (at the 'target' end) ie . the cable 'Tx' lead connects to the Beagle 'Rx' pin, and vicer versa Mar 23 21:01:11 KotH & veremit - ok, black pin is on J1. do any of the other wires need to be on a jumper and where? Mar 23 21:01:51 faddah .. Yes. Mar 23 21:02:04 veremit - i am not an electronics genius, i just wanted a small board to play with and write some node.js stuff. this is getting very frustrating and i'm about to call element14 and ship back the whole thing. Mar 23 21:02:24 faddah .. probably better witha PC :) Mar 23 21:02:25 veremit - in other words, i have no meter. i have small screw drivers, that's about as far as my tools go. Mar 23 21:02:29 or .. some other computer Mar 23 21:02:39 veremit - i have no other computers Mar 23 21:04:08 faddah .. maybe wanna try out something like .. https://www.codebox.io/stack/node Mar 23 21:06:29 veremit - i already know about things like codebox, cloud9, koding, nitrous.io, etc., and used them. Mar 23 21:06:44 ok cool Mar 23 21:07:24 problem with boards like the pi, arduino and beagle .. you need ot be prepared to get your "hands dirty" :) that's all I'm saying. Mar 23 21:07:33 veremit & KotH - sigh. so you are saying i cannot use this with a chromebook, you cannot point me at _current_ instructions that show me how to use the debug cable with the pins, and i have no way to diagnose why i can no longer ssh in to the board? is that what you're saying here? Mar 23 21:08:11 my debug cable only has _four_ wires - red, green white black Mar 23 21:08:21 * veremit fears .. Mar 23 21:09:11 faddah .. give me a moment Mar 23 21:12:40 hi everyone Mar 23 21:13:17 Looking for some help here... Mar 23 21:14:20 faddah: sorry, i wasnt reading Mar 23 21:14:25 faddah: it should be possible Mar 23 21:14:34 faddah: i dont know what problems you face Mar 23 21:14:38 :D Mar 23 21:14:47 faddah: a debug cable is usally pretty straight forward to use Mar 23 21:14:55 So I'm trying to use this http://beaglebone.cameon.net/home/joystick Mar 23 21:15:15 it says to use the command line: npm install joystick Mar 23 21:16:11 smurray: you have a second? Mar 23 21:16:13 faddah .. does it look at all like this .. http://embest-tech.com/product/extension-module/uart8000-u.html .. you can try that pinout Mar 23 21:16:31 faddah .. otherwise .. you're probably going to find it easier to get a uSD card, download a reflasher, and start again. Mar 23 21:17:06 faddah .. ignore the white. Mar 23 21:17:22 KotH .. hope to God, those are wire colours for USB :( Mar 23 21:18:20 * KotH does not trust wire colours Mar 23 21:18:20 bloody ele14. Mar 23 21:18:35 KotH .. no .. once I've snipped the cable apart .. then I do :) Mar 23 21:18:49 or buzzed it out .. standard electronics tests. Mar 23 21:18:51 anyone: How do I install this? http://beaglebone.cameon.net/home/joystick Mar 23 21:19:02 wtf is "npm" Mar 23 21:19:36 it says to use the command line: npm install joystick Mar 23 21:19:45 to install it Mar 23 21:19:49 yes, in node ide Mar 23 21:19:53 but that don't work Mar 23 21:19:57 what does it say? Mar 23 21:20:03 sec... Mar 23 21:20:15 it won't work on the command line .. or does it .. (never used the Node images) Mar 23 21:20:24 KotH & veremit - sorry, i was on the phone with element14 trying to see if they could point me to the kit on their web site or help me. Mar 23 21:20:32 module.js:340 throw err; ^ Error: Cannot find module '/opt/cloud9/build/standalonebuild/npm' at Function.Module._resolveFilename (module.js:338:15) at Function.Module._load (module.js:280:25) at Function.Module.runMain (module.js:497:10) at startup (node.js:119:16) at node.js:902:3 Mar 23 21:20:43 Zock .. yikes. Mar 23 21:21:04 ok that one is outta my league .. sorry .. Mar 23 21:21:22 Zock: this is not a node.js help channel Mar 23 21:21:24 faddah .. have had a comb around their site .. I Agree, its f*in useless Mar 23 21:21:26 where am I supposed to use the command line? Mar 23 21:21:47 KotH .. well some muppet packaged it with the beagle sw :p Mar 23 21:21:59 this is the kit i bought on-line via amazon, i have no way of knowing where the debug cable came from: http://www.amazon.com/BeagleBone-Black-Single-Computer-Development/dp/B00P48PQTS/ref=sr_1_6?ie=UTF8&qid=1427145659&sr=8-6&keywords=beaglebone+black+kit Mar 23 21:22:47 Zock .. are you using debian or angstrom? Mar 23 21:23:09 I'm using whatever it came with Mar 23 21:23:27 I think its bonescript? Mar 23 21:23:47 * veremit grumbles about amazon too Mar 23 21:23:56 Zock: oh.. damn... that beast Mar 23 21:23:58 I'm having a bit of a headache with the beaglebone black Mar 23 21:23:59 Zock .. no, it'll be running an operating sstem beneath Mar 23 21:24:00 Zock - bonescript is the JavaScript module lib that comes with beaglebone to access the hardware. Mar 23 21:24:05 Zock: sorry, didnt say anything.. please keep asking Mar 23 21:24:23 I'm trying to setup an LCD screen that uses an SPI chip on the latest ubuntu images Mar 23 21:25:01 and after reading and reading and reading about cape manager and how I can define my own stuff in the device tree Mar 23 21:25:13 So where do I put commands? Mar 23 21:25:15 it turns out that debian kernel 3.14 does not have a cape manager anymore :) Mar 23 21:25:21 Im new to this Mar 23 21:25:54 so here I am .. not wanting to compile a device tree that gets loaded at boot time .. since that pretty much means I'm gonna crash the bbb Mar 23 21:26:13 Zock .. did you follow the other articles in that dude's tutorial, or just that one? Mar 23 21:26:13 All it says is "Install the node-joystick module with this command line: npm install joystick" Mar 23 21:26:14 and trying to get some ideas from other folks that maybe had this problem Mar 23 21:26:23 Just that one :( Mar 23 21:26:43 Zock - can you ssh into the beagleboane? if so, do cat /proc/version Mar 23 21:26:47 Zock .. right, that article is most likely out-of-date for your beagle Mar 23 21:26:50 Victor__: so, what's the problem with crashing your BBB? Mar 23 21:27:06 Zock - cat /proc/version will tell you your distro Mar 23 21:27:21 I will try that. just a sec Mar 23 21:27:28 Koth: I'll end up with an unbootable bbb and I'll have to reflash it again Mar 23 21:27:29 faddah: actually, you shouldnt use that, but `uname -a` instead Mar 23 21:27:34 Victor__: so? Mar 23 21:28:01 KotH - i've used both, depending Mar 23 21:28:03 Victor__: let me guess, you dont have a serial cable connected to the debug port? Mar 23 21:28:05 KotH: since I'm in trial and error mode I would like to avoid spending 10 minutes of flashing for trying a one line change in the dtbs Mar 23 21:28:17 faddah: you should always use uname, it's portable. /proc/version is not Mar 23 21:28:20 KotH: :D you have a webcam in my room or something :P Mar 23 21:28:41 It gave me this: Linux version 3.8.13-bone47 (root@imx6q-wandboard-2gb-0) (gcc version 4.6.3 (Deb ian 4.6.3-14) ) #1 SMP Fri Apr 11 01:36:09 UTC 2014 Mar 23 21:28:49 Victor__: no, but i but people who dont use serial cables give off a certain smell Mar 23 21:29:03 KotH: I connected the BBB through the miniusb for power and ethernet for network Mar 23 21:29:09 Mar 23 21:29:18 Sorry, that is: Linux version 3.8.13-bone47 (root@imx6q-wandboard-2gb-0) (gcc version 4.6.3 (Debian 4.6.3-14) ) #1 SMP Fri Apr 11 01:36:09 UTC 2014 Mar 23 21:29:56 KotH: I tried connecting on the serial over usb but it doesn't show the boot messages .. it only displays the serial output of the bbb after the macbook sees the serial connection Mar 23 21:30:12 Zock, ok, yer on debian, Mar 23 21:30:31 Cool! good to know! Mar 23 21:30:33 KotH: would that completely change if I'd use the 6 pins dedicated for the serial ? would I be able to see the boot process and jump in Mar 23 21:30:35 Victor__: first connect the serial cable, then boot the bbb Mar 23 21:30:44 I just tryed "npm install joystick" from ssh Mar 23 21:31:06 Zock .. the node.js installed on your bealge is not configured the same way as that tutorial expects. Mar 23 21:31:07 Victor__: you dont expect your monitor show what happend 5 minutes ago, when you switch it on, do you? Mar 23 21:31:17 It said: npm http GET https://registry.npmjs.org/joystick Mar 23 21:31:43 Victor__: eh.. use the debug port, not the usb port Mar 23 21:31:44 KotH: true that, but wouldn't it be normal to get the same serial behavior over the standard USB connection ? Mar 23 21:31:48 no Mar 23 21:31:53 Victor__ .. if you're going to work with embeded devices, you're gonna have to build a kernel once in a while . . IF you're unlucky .. you'll brick it .. but you can get back from a downloaded flasher image most likely Mar 23 21:31:57 Victor__: for usb to work, the os has to be running already Mar 23 21:32:01 veremit Ahh Mar 23 21:32:26 Everyone: Serial debug is your FRIEND :D Mar 23 21:32:30 So I got issues Mar 23 21:32:37 KotH: oh .. I got past the point of rebuilding the kernel :D I was able to do it both on the bbblack (it took hours) and on an Ubuntu machine with the cross compiler Mar 23 21:33:02 oh, you are one of those guys who do ethical builds! Mar 23 21:33:05 KotH & veremit - o.k., that debug cable pic you sent me is like mine, only mine is much, much shorter, like 3 feet, tops Mar 23 21:33:23 faddah .. yes I See what you have .. but we're still at a bit of a loss on documentation Mar 23 21:33:33 KotH: anyway, I'll give it a shot with the serial debugger from the board pins not via usb .. I'm not afraid of jacking the system .. I just want to minimize the time of reverting it back to a previous stable state Mar 23 21:34:04 Victor__ .. burn a uSD card with a flasher .. everything will be fine :D Mar 23 21:34:13 Victor__: that's necessary pain so that the child learns properly ;-> Mar 23 21:34:18 veremit - ok, trying to call eleduino, who sold the board through amazon... Mar 23 21:34:33 worst case playing with dtbs is everything will boot .. .but it will throw some error Mar 23 21:34:38 its really not that dangerous Mar 23 21:34:42 why do people always talk about "burning" sd cards... you dont burn them.. you dont even flash them Mar 23 21:34:52 KotH .. elec sland :p Mar 23 21:34:57 :) Mar 23 21:34:58 slang* Mar 23 21:34:59 veremit: it's not EE slang Mar 23 21:35:10 Koth .. not for .. uhm .. Mar 23 21:35:11 veremit: it's i-dont-know-what-i-am-talking-about slang Mar 23 21:35:25 koth .. level with 'em .. Mar 23 21:35:31 lol Mar 23 21:35:36 * KotH does not level with anyone Mar 23 21:35:40 or nobody gets anywhere Mar 23 21:35:44 unless he/she knows more than i do :) Mar 23 21:35:54 no comment. Mar 23 21:36:00 * KotH is an arrogant asshole Mar 23 21:36:06 no comment. Mar 23 21:36:07 * KotH knows it Mar 23 21:36:15 and now another shot in the dark hoping a saviour angel is here : does anyone have any sort of experience with the HX8357 LCD SPI module ? Mar 23 21:36:31 obviously under bbb Mar 23 21:36:49 KotH & veremit - just wish there were troubleshooting instructions on the beagleboard.org web site that were easy to access and showed you in pics where to take the latest serial2debug cable and where to put it on the pins. putting the debugging/troubleshooting instructions on the web page on the board is useless if the board goes down. Mar 23 21:36:50 Victor__ .. short answer here... No :) Mar 23 21:37:18 faddah: hmm.. Mar 23 21:37:23 faddah: nothing on elinux either? Mar 23 21:37:27 faddah .. don't we all .. but there are several variants of the debug cable .. Thankfully, as KotH pointed out .. the debug header is Standard. and publicised in the SRM on the beagle elinux site Mar 23 21:37:40 or we'd all be pissing in the wind Mar 23 21:37:42 veremit: I figured .. :) Mar 23 21:37:59 veremit: been there, done that, got wet pants Mar 23 21:38:00 veremit & KotH - what is the elinux site for beagle? Mar 23 21:38:07 faddah: www.elinux.org Mar 23 21:38:17 KotH .. yeah, tend to avoid that .. or piss downwind ;) Mar 23 21:38:20 faddah: there are many sections that contain info about the bbb Mar 23 21:38:39 faddah: i havent had a look there in ages, so i cannot tell you where to start Mar 23 21:39:17 faddah .. try Mar 23 21:39:22 faddah .. try http://elinux.org/Beagleboard:BeagleBoneBlackhttp://elinux.org/Beagleboard:BeagleBoneBlackhttp://elinux.org/Beagleboard:BeagleBoneBlackhttp://elinux.org/Beagleboard:BeagleBoneBlackhttp://elinux.org/Beagleboard:BeagleBoneBlackhttp://elinux.org/Beagleboard:BeagleBoneBlackhttp://elinux.org/Beagleboard:BeagleBoneBlackhttp://elinux.org/Beagleboard:BeagleBoneBlackhttp://elinux.org/Beagleboard:BeagleBoneBlack Mar 23 21:39:26 omfg this PC needs a reboot Mar 23 21:39:35 yeah NOT that Mar 23 21:39:42 faddah .. try http://elinux.org/Beagleboard:BeagleBoneBlack Mar 23 21:39:55 faddah: but part of the problem is, that those who know that kind of stuff are usually people who have been doing it for ages, so they dont think that anyone would struggle with that kind of thing Mar 23 21:40:38 * KotH is no exception Mar 23 21:41:08 KotH: hi OpenSuse Mar 23 21:41:23 jamesaxl: SuSE 6.0, please Mar 23 21:41:40 * KotH still has the box somewhere Mar 23 21:41:43 they dropped the 'open' tag :D Mar 23 21:41:52 veremit: it didnt exist back then ;) Mar 23 21:41:53 KotH: but i will feel free(freedom) when i say opensuse Mar 23 21:42:08 jamesaxl: i'm not a fan of susi Mar 23 21:42:15 *facepalms* and heads for the kitchen .. Mar 23 21:44:28 KotH & veremit - i think what i have is the adafruit debug cable - http://elinux.org/Beagleboard:BeagleBone_Black_Serial#Adafruit_4_Pin_Cable_.28PL2303.29 Mar 23 21:45:55 faddah .. if it says .. oh wait .. chrome .. no dmesg or "Device Manager" on the host side :( Mar 23 21:46:08 faddah .. try that pinout then Mar 23 21:46:20 you can swap 4/5 if it doesn't work first-time Mar 23 21:46:24 KotH & veremit - so i have the black cable in the right place for the J1, green is receive and white is transmit, i just need to know where white & green go. Mar 23 21:46:34 pin4/5 Mar 23 21:46:36 on the beagle Mar 23 21:47:27 i need a little hlep Mar 23 21:47:38 i am trying to log back into my BBB after bricking it Mar 23 21:47:47 but i don't have an HDMI cable/monitor Mar 23 21:47:51 what is my best path forward? Mar 23 21:48:24 loveslap .. make a new uSD card with a 'flasher' image from the web, plug in and reboot Mar 23 21:48:55 veremit - is the black plugged into J1 considered '0' or '1'? Mar 23 21:48:59 by 'reboot' I mean .. unplug Everything, insert card, plug back in. Mar 23 21:49:08 faddah .. pin 1 will be marked Mar 23 21:49:32 we count headers from '1' :) only in code is '0' the start point! Mar 23 21:50:35 veremit i will try with BBB-eMMC-flasher-ubuntu-14.04.2-console-armhf-2015-02-19-2gb.img Mar 23 21:51:50 i'm running this command on OSX Mar 23 21:51:52 sudo dd if=BBB-eMMC-flasher-ubuntu-14.04.2-console-armhf-2015-02-19-2gb.img of=/dev/rdisk1 bs=1m Mar 23 21:52:32 look okay? Mar 23 21:52:42 do i need to format the sd in some way first? Mar 23 21:53:50 loveslap .. no need to format .. the 'dd' will sort all of that Mar 23 21:53:53 Ok, I am back from work. Mar 23 21:54:22 veremit & KotH - ok, so beagle has J1 - black, pin 4 - green, receive, pin 5 - white, transmit. Mar 23 21:54:53 faddah .. sounds good Mar 23 21:55:28 veremit & KotH - bbb is plugged in with serial2debug cable and powered on, on-board LEDs flashing like normal. now what, please? Mar 23 21:55:44 faddah: press the reset button Mar 23 21:55:57 faddah: sounds like you are just trying to get a serial connection to your BBB? Mar 23 21:56:02 faddah: you should see the bootloader, the second stage boot loader, then the linux kernel boot Mar 23 21:56:10 (yep) Mar 23 21:56:18 :) Mar 23 21:56:48 faddah .. have you started a terminal program to access your debug cable? Mar 23 21:57:07 youl'l need the 'terminal' running when you start up the beagle Mar 23 21:57:10 KotH & veremit - "where" am i going to "see" all this, and "where" is the reset button? Mar 23 21:57:20 I have a few questions. I assume more people are active than last night? Mar 23 21:57:30 Seeems like it :P Mar 23 21:57:44 Faddah, which OS are you using for your computer you're on Mar 23 21:57:51 SpyKu .. it comes and goes .. Mar 23 21:57:58 speakin of .. I need to brb and make a coffee lol Mar 23 21:58:16 johnpaul - i've been going through this with KotH & veremit for an hour or more, it's on a Chromebook/linux Mar 23 21:58:19 make me some tea pl0x :P Mar 23 21:58:33 Does crosh have screen? Mar 23 21:58:38 the command, that is. Mar 23 21:59:03 You can download "Secure Shell" for chrome browser :P Mar 23 21:59:05 KotH & veremit - i have a terminal window, several of them. what do i do to "see" the board? ssh in? to the same 192.168.7.2 address? Mar 23 21:59:40 faddah: if you are using a debug cable, you don't SSH to the bbb Mar 23 21:59:50 johnpaul & SpyKu - i all ready am in dev mode on Chromebook and know how to terminal or secure shell, thank you, though. Mar 23 22:00:15 does the Chromebook come with USB serial drivers? Mar 23 22:00:15 faddah: inside of the Chrome Shell, can you use the command 'screen' Mar 23 22:00:48 ddrownL not too sure, but it is essentially linux and may Mar 23 22:00:59 johnpaul, veremit & KotH - "bash: screen: command not found" Mar 23 22:02:38 Anyone run https://rcn-ee.net/rootfs/2015-02-19/ubuntu-14.04.2-console-armhf-2015-02-19.tar.xz on BeagleBoard and experience a crash that happens? Mar 23 22:02:52 okay Mar 23 22:02:58 i've completed the dd command Mar 23 22:02:58 and I also was in here trying to find a way to compile the latest TOR but to no avail. Was trying all weekend Mar 23 22:03:02 i put the sd in the BBB Mar 23 22:03:04 power up Mar 23 22:03:12 do i need to hold the button at the same time? Mar 23 22:03:21 and how do I log in? Mar 23 22:03:30 (don't have an HDMI cable) Mar 23 22:03:42 ssh Mar 23 22:03:51 need to netscan to find what IP it is Mar 23 22:04:03 netscan is a program? Mar 23 22:04:06 KotH, veremit & johnpaul - so how do i see what's going on with the beagleboard thru the debug cable? i have a terminal window up Mar 23 22:04:06 for osx? Mar 23 22:04:10 faddah: what is the output of ls /dev Mar 23 22:04:11 nmap is one you can use Mar 23 22:04:48 nmap 192.168.1.0/24 -sP Mar 23 22:04:56 or whatever ip ran your LAN uses Mar 23 22:04:56 okay i'm installing nmap with homebrew Mar 23 22:05:00 *range Mar 23 22:05:16 nmap -v -sn 192.168.0.0/16 Mar 23 22:05:20 something like that? Mar 23 22:05:36 KotH: what's you choice concerning OS Mar 23 22:05:43 johnpaul - a _lot_. what specifically are you looking for from "$ ls /dev"? Mar 23 22:06:00 jamesaxl: whatever floats your boat and you can efficiently work with Mar 23 22:06:26 is there any kernel for bbb, that can get MUSB+DMA working? i am having issues with usb devices in isochronous mode and they work only with CONFIG_MUSB_PIO_ONLY=y Mar 23 22:06:51 johnpaul - are you looking for /sda*, are you looking for tty*, are you looking for usbmon*? Mar 23 22:06:52 faddah: anything tty that may say USB or something Mar 23 22:07:06 KotH: every OSs floats boat, but which one will bring in the other side ? Mar 23 22:07:15 i plugged it in with nothing else attached Mar 23 22:07:19 bring you* Mar 23 22:07:19 faddah: ttyUSB* ttyACM* are two patterns that might match Mar 23 22:07:20 and its doing the cylon thing Mar 23 22:07:22 ? Mar 23 22:07:23 good Mar 23 22:07:30 faddah: I am not sure of support on ChromeOS with serial connections. so just checking to see if the device can see the usb device Mar 23 22:07:42 faddah: okay what is the ttyUSB full device name Mar 23 22:08:23 johnpaul, KotH & veremit - there is tty, tty1, tty8, ttyUSB0, there is also usbmon0, usbmon1 & usbmon2 Mar 23 22:08:48 * KotH goes to sleep Mar 23 22:09:16 i appear to have bored KotH Mar 23 22:09:19 KotH: you seep too soon Mar 23 22:09:24 sleep* Mar 23 22:09:26 faddah: nah.. just past my bedtime Mar 23 22:09:30 faddah: does running: stty -F /dev/ttyUSB0 Mar 23 22:09:33 faddah: should have been asleep for an hour already Mar 23 22:09:37 KotH - where are you? Mar 23 22:09:41 faddah: but i needed to fix a bug in koha first Mar 23 22:09:50 does that work* i meant Mar 23 22:09:55 KotH: bcs i will need you to build my "spiquadcopter" Mar 23 22:09:56 KotH - portland, oregon, u.s. here. Mar 23 22:10:02 faddah: a 3rd world country in the middle of europe Mar 23 22:10:26 KotH - prague? Mar 23 22:10:31 almost Mar 23 22:10:40 faddah: western germany Mar 23 22:10:54 KotH i was in istanbul, prague, germany & paris in 2010 Mar 23 22:11:08 KotH - my family is originally from nuremburg Mar 23 22:11:35 faddah: nüremberg is a nice city, liked it... but here... well... Mar 23 22:12:23 KotH - frankfurt? koln? munich? Mar 23 22:13:19 johnpaul, KotH & veremit - here's the result of "stty -F /dev/ttyUSB0" => speed 9600 baud; line = 0; -brkint -imaxbel Mar 23 22:13:28 faddah: does stty -F /dev/ttyUSB0 show anything / work? Mar 23 22:13:32 ah okay Mar 23 22:13:34 great Mar 23 22:13:35 KotH: https://www.youtube.com/watch?v=IW2Qtio-7co Mar 23 22:13:42 faddah, can you download https://chrome.google.com/webstore/detail/diginow-serial-terminal/kfmecbejcnepbfdcdbbhfcjmdmmcmoah Mar 23 22:13:50 it is a chrome extension for serial comm Mar 23 22:14:06 you'll want to set the baud rate in the top left to 115200 Mar 23 22:14:48 KotH: try to listen it and you sleep tight, you will feel seems like in a Wolke Mar 23 22:16:32 ok, got the diginow serial terminal Mar 23 22:16:53 pardon, the above was meant for ^^^^ KotH, johnpaul & veremit Mar 23 22:16:57 okay, set the top left box to 115200 (baud rate that the BBB uses) Mar 23 22:17:08 and then clcik on ttyUSB0 Mar 23 22:17:22 you may have to press enter in the send button to get some output Mar 23 22:17:51 KotH, veremit & johnpaul - yeah, i ain't seen 9600 baud since 1996. ;) Mar 23 22:18:20 hmm Mar 23 22:18:25 seems to flash very fast Mar 23 22:18:30 and not sucessfully Mar 23 22:18:50 only 5 minutes from cyclon pattern to all lights on Mar 23 22:18:52 faddah: haha, some small devices seem to use 9600. a lot in networking are defaulted to that, apparently Mar 23 22:19:10 faddah: do you see any output Mar 23 22:20:33 johnpaul, KotH & veremit - wait, i see no way to change it from 9600 baud. i click on "baud rate: 9600" and all that does is make the window for this app larger. Mar 23 22:20:57 faddah: in that top left text box, you should be able to type 115200 Mar 23 22:21:49 faddah: i think he drinks a lot of beer Mar 23 22:22:46 johnpaul, KotH & veremit - nope, "baud rate: 9600" is grey, cannot click it or change it. there were up and down arrows next to "9600," now they are gone. badly designed app. Mar 23 22:23:26 jamesaxl - huh?? Mar 23 22:23:43 jamesaxl - who drinks a lot of beer? what does that have to do with my issue? Mar 23 22:23:51 faddah: yea, the problem is that you're on ChromeOS and support is literally limited to what people have created as extensions. Windows/(full) Linux/Mac have much better support for this. Mar 23 22:24:12 johnpaul - sigh. don't i know it. Mar 23 22:24:19 johnpaul .. surely there's some terminal 'app' ? Mar 23 22:24:19 faddah: i meant Koth drunk a lot of beer , you problem , you gonna resole just be patient Mar 23 22:24:33 how do I display my RSA key? what is the command? Mar 23 22:24:50 veremit - i have a terminal app! i have lots of terminal tabs open! just please tell me what to do with them! johnpaul, KotH & veremit Mar 23 22:25:00 SpyKu .. why do you want to see your RSA key!? Mar 23 22:25:17 faddah .. you probably don't want them all open at once ;) Mar 23 22:25:19 SpyKu: you can find it in .ssh folder Mar 23 22:25:23 to check that there is no M-I-T-M - goin on :p Mar 23 22:25:26 pick one .. go through the process .. eliminate if it doesn't work Mar 23 22:25:57 veremit KotH johnpaul - i can have one or as many terminals open as you like, please. just please tell me what to do with the terminal. i have repeated that now several times. Mar 23 22:26:00 jamesaxl .. that won't work for the server key ;D Mar 23 22:26:02 nano ssh_host_rsa_key.pub ? Mar 23 22:26:39 faddah .. open 1 serial terminal app .. go to 'configure' set your baud rate to 115200, 8 data bits, no parity, 1 stop bit .. no flow control .. 'connect' Mar 23 22:27:13 faddah - You need a terminal that supports serial connections. ChromeOS is limited it seems with good apps. I don't have a Chromebook at the moment so I can't test Mar 23 22:27:20 veremit - ChromeOS has no such settings for the terminal - you get a commandline screen, that's it. Mar 23 22:27:53 hrm. Mar 23 22:27:57 faddah: from the crosh terminal, 'cat' may work, but you won't be able to send information, i.e. it will be for viewing only Mar 23 22:28:56 faddah: try this app Mar 23 22:28:59 faddah: https://chrome.google.com/webstore/detail/beagle-term/gkdofhllgfohlddimiiildbgoggdpoea Mar 23 22:29:34 https://chrome.google.com/webstore/detail/serial-monitor/ohncdkkhephpakbbecnkclhjkmbjnmlo?hl=en Mar 23 22:29:37 johnpaul , faddah .. just spotted that 'BeagleTerm' Mar 23 22:29:48 what I posted should work VIA chrome browser Mar 23 22:30:02 faddah veremit :P Yea, it actually looks functional Mar 23 22:30:46 * veremit checks the demo video . Mar 23 22:31:10 i am looking for bbb image with TI kernel. any links? Mar 23 22:31:27 https://rcn-ee.net/ ? Mar 23 22:31:48 johnpaul veremit KotH - ok, got BeagleTerm, launched it, it sees the device at /dev/ttyUSB0 , and is connected at 115200 baud. it says: Device found /dev/ttyUSB0 connection Id 5 Mar 23 22:31:56 hurrah Mar 23 22:32:02 great! Mar 23 22:32:11 step one complete :P Mar 23 22:32:18 faddah: send like an enter command or something if you see nothing Mar 23 22:32:36 ie. hit the enter key :p Mar 23 22:32:50 you should get a prompt in response Mar 23 22:32:51 veremit : touché Mar 23 22:32:55 johnpaul, veremit KotH - ok, doing that Mar 23 22:33:03 :) Mar 23 22:33:19 got: "Debian GNU/Linux 7 beaglebone ttyO0 default username:password is [debian:temppwd] Support/FAQ: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian The IP Address for usb0 is: 192.168.7.2 beaglebone login: " Mar 23 22:33:36 ah beauty Mar 23 22:33:43 faddah: boom Mar 23 22:33:54 SpyKu: tnx, but i am looking for something older like 3.2 based on TI mainline, where i can possibly get usb+dma working Mar 23 22:33:56 faddah: now you can login with debian / temppwd Mar 23 22:34:00 veremit johnpaul - i have debian 7.4 on this, btw, i think that's the latest shipped image Mar 23 22:34:30 johnpaul veremit - log-in as root? that's what i was doing as ssh Mar 23 22:34:32 asdf123_ .. usb host is a problem. Mar 23 22:34:53 asdf123_ usb+dma is a disaster Mar 23 22:34:54 faddah: you can log in as debian or as root, whatever you prefer Mar 23 22:35:01 yes, exactly... MUSB+DMA = HELL Mar 23 22:35:15 does not work on any torvalds kernels Mar 23 22:35:20 asdf123_ I'm not sure there is ANY way it works Mar 23 22:35:26 so i am looking for something TI based... Mar 23 22:35:31 asdf123_ I'm not sure there is ANY way it works Mar 23 22:35:34 ok, i'm logged in. now how do i diagnose why the usb regular connection was not working and i could not ssh? Mar 23 22:35:46 faddah "ifconfig -a" should show you interfaces Mar 23 22:35:48 i guess TI somehow got it working on their mainline kernels... Mar 23 22:36:02 asdf123_ I doubt it .. the usb driver (from ANYwhere) is very VERY basic Mar 23 22:36:03 faddah: well, that is a linux tihng to try and diagnose.. you can look at ifconfig and see what it says there Mar 23 22:36:30 veremit johnpaul - pasting that to a gist, hang on Mar 23 22:36:34 faddah veremit: I am actually at work right now, and need to get to a meeting. I will check back in like 20-30 minutes. Mar 23 22:36:43 asdf123_ and broadly speaking .. very broken too .. since it was ported from another device Mar 23 22:36:49 johnpaul np, thanks Mar 23 22:37:16 noticed some patches like: https://lkml.org/lkml/2014/1/24/195 Mar 23 22:37:30 Can anyone help me compile latest source of tor? Mar 23 22:37:49 seem related to the musb+dma in isochronous issues... Mar 23 22:38:25 SpyKu .. wrong channel Mar 23 22:38:51 but I am using beagleboard Mar 23 22:38:56 SpyKu .. alternatively there may be a debian package already built :P for arm. Mar 23 22:39:31 i've tried instructions VIA tor website and it installs old version :/ Mar 23 22:39:31 SpyKu .. otherwise you need to set up a cross-compile toolchain and development environment .. or make space on the beagle itself .. and Wait. Mar 23 22:40:15 johnpaul - understood, thank you for help thus far Mar 23 22:40:54 KotH, johnpaul & veremit - result from "ifconfig -a" — https://gist.github.com/faddah/67c5c0a5aca69cb4c9dd Mar 23 22:40:56 faddah .. "/etc/init.d/sshd status" and/or "/etc/init.d/sshd restart" Mar 23 22:42:13 or is it .. hrm .. its not dropbear is it .. Mar 23 22:42:47 veremit johnpaul KotH - "/etc/init.d/sshd status" returns "-bash: /etc/init.d/sshd: No such file or directory" Mar 23 22:43:04 faddah .. replace 'sshd' with 'dropbear' Mar 23 22:43:57 veremit - there's ssh in there but not sshd Mar 23 22:44:05 no wait .. drop the 'd' .. just checked my debian box Mar 23 22:44:15 lol Mar 23 22:44:24 veremit -- sshd is in /usr/bin/sshd Mar 23 22:44:42 yeah there'll be some debian fugery Mar 23 22:44:44 veremit - yeah, there's no dropbear in there. Mar 23 22:45:00 dropbear is alightweight sshd Mar 23 22:45:52 veremit - just did "which dropbear" from root of beaglbone and it doesn't have any Mar 23 22:46:04 faddah .. if youre prepared for a large cut/paste .. try 'dmesg" :) Mar 23 22:46:39 faddah .. and 'cat /var/log/messages' Mar 23 22:47:04 something in there should hint at any issues Mar 23 22:47:22 How would I build from souce from my beagleboard? Mar 23 22:48:02 veremit - it's now at the bottom of the git — https://gist.github.com/faddah/67c5c0a5aca69cb4c9dd Mar 23 22:48:13 s/git/gist Mar 23 22:48:53 veremit - so what am i looking for in all that? Mar 23 22:52:10 vermit, just did "/etc/init.d/ssh status" (without the 'd' for daemon) and it returned this: ssh.service - LSB: OpenBSD Secure Shell server Loaded: loaded (/etc/init.d/ssh) Mar 23 22:52:48 veremit (cont'd.) - Apr 23 20:20:00 beaglebone sshd[965]: Server listening on 0.0.0.0 port 22. Apr 23 20:20:00 beaglebone sshd[965]: Server listening on :: port 22. Mar 23 22:53:15 faddah .. ssh results look good Mar 23 22:53:28 SpyKu .. apt-get install build-essential Mar 23 22:53:34 veremit - so why can't i ssh in on a direct USB connection? Mar 23 22:53:41 SpyKu .. wget Mar 23 22:53:58 faddah .. I suspect some usb_gadget issue .. hence 'dmesg' and 'cat /var/log/messages' Mar 23 22:54:47 veremit - i haven't done cat /var/log/messages yet, want me to do that? Mar 23 22:56:14 faddah yup Mar 23 22:56:16 brb Mar 23 22:58:16 ahh ok thanks Mar 23 22:58:25 * SpyKu gives beer to veremit Mar 23 22:58:51 back Mar 23 22:58:56 chrs for beer :) beer is good Mar 23 22:59:02 beer and coffee .. just not together Mar 23 22:59:25 haha :P Mar 23 23:01:14 What about kahlua? Mar 23 23:03:26 omg .. I saw the return of the "rocket fuel" coffee (with guava) in the work kitchen .. lol Mar 23 23:03:49 veremit - that 'cat /var/log/messages' crashed the BeagleTerm app - there was oodles of stuff in there taking forever to load going back to when the kernel on the board was initialized (Jan 01 00:00:11). Mar 23 23:04:18 veremit & SpyKu - and beer with coffee in it is usually a porter. Mar 23 23:04:45 faddah .. oh bugger, and heh :p Mar 23 23:06:28 Okay, I am back, and now with some questions of my own. :) Mar 23 23:07:29 * SpyKu is a n00b at linux Mar 23 23:07:42 I am pretty new to embedded linux (decent with Linux itself, though) but I was curious: When interfacing with hardware, via pwm, spi, gpio, etc, is it typical that you modify/read the contents of files to control them? Mar 23 23:07:58 i restartd beagleterm and it continue in cat - ack! how do i stop it? ^C? Mar 23 23:08:11 Yea Mar 23 23:08:14 johnpaul .. the options are mixed .. /sys interface is one .. shared mem is another .. Mar 23 23:08:20 PRU's are a good one Mar 23 23:08:34 depends what you wanna do really Mar 23 23:08:59 realtime you're gonna need ot look at PRUs .. Mar 23 23:09:05 veremit .. I have been using /sys to interface with them, just using an fstream in C++ to read/write values, but it seems strange to me. Mar 23 23:09:29 currently not worried about real-time - yet. that will be for one day down the road :) Mar 23 23:10:41 veremit .. I am currently working with PWM to control a servo. I don't really mind which way to do this, I just want to make sure that I am doing it correct from a professional/engineering standpoint, not a hacky way. Mar 23 23:11:44 veremit .. and from what I have seen, the documentation is a little sparse or I am too new / not knowledgable enough to read them. Have you done anything with C++ / PWM? Mar 23 23:12:41 johnpaul .. not on the beagle ever .. if it were me, I'd go with a cortex chip and use direct register access .. very dangerous in linux .. or arduino and use spi/uart to control Mar 23 23:13:12 Hello everyone. Is there a issue to used eqep0 on kernel 3.14 ? because i tried every combinaisons to configure P9_42 but i failed to get 3.3v on the eqep0A pin :'( Mar 23 23:13:29 veremit .. doing it with arduino is easy :P and the beaglebone is a cortex A chip, no? Mar 23 23:13:59 johnpaul .. yes .. different breed :) Mar 23 23:14:11 was thiking more the M-series :D Mar 23 23:14:16 wb faddah Mar 23 23:14:37 back Mar 23 23:15:06 that 'cat /var/log/messages' crashed me something fierce, which i've never seen happen on a Chromebook before. Mar 23 23:16:04 weird .. musta flooded a buffer or something Mar 23 23:16:27 veremit & johnpaul - so long story short, how to i get the beaglebone black board to a) stop the 'cat'; b) restart the ssh server; c) restart the whole board (as in shutting down and restarting debian linux), all from the command line, in that order? Mar 23 23:16:46 faddah_ .. Ctrl-C should stop .. or it will End eventually Mar 23 23:16:49 veremit & johnpaul - i believe that is what will fix me, i think Mar 23 23:16:49 veremit .. ah okay. I do have a few M4 microcontrollers, but trying to stay with full embedded linux. Mar 23 23:17:12 johnpaul .. I'm sure its possible .. I've just never heard of a 'good' solution yet. Mar 23 23:17:40 faddah_ .. if you can get a prompt up again .. "sudo reboot" or just "reboot" will do a clean shutdown/restart Mar 23 23:17:41 faddah_ .. the beaglebone has a reset and power button on it, near the USR LEDs Mar 23 23:18:09 faddah_ .. I'm thinking in your case you might wanna do a filesystem check .. but not sure that'll work on a running system Mar 23 23:18:22 veremit johnpaul - just, if i launch BeagleTerm again to get in there, i'm afraid it'll still be in the middle of 'cat /var/log/messages' and will freeze/crash my Chromebook again. Mar 23 23:18:38 veremit johnpaul - had to restart whole damn Chromebook to get back here. Mar 23 23:18:52 veremit .. Okay, :P Thanks, that is what I keep coming up with. I just know it is possible and it is frustrating trying to figure it out. I need some code written so I can present it for a potential interview, so I have been working on a small project. this is where I have been hitting a wall Mar 23 23:18:54 faddah_ it will continue disconnected .. shoulda done by now Mar 23 23:19:25 johnpaul .. what's the 'wall' ? Mar 23 23:19:49 veremit johnpaul - it was taking a looooooooooong time, still on log entries from april of last year when board/kernel was created/initialized. Mar 23 23:20:02 wonder if the filesystem is full .. lol. Mar 23 23:20:18 really surprised RCN/etc haven't put logrotate on there. Mar 23 23:20:48 veremit johnpaul - so '$ fsck.ext4 -f ...' on which /dev/? Mar 23 23:20:51 veremit .. successfully controlling a servo via PWM. :) Mar 23 23:21:20 veremit .. on the BBB Mar 23 23:21:48 johnpaul .. I'm sure you're not the first :) Mar 23 23:22:06 faddah_ .. it would be /dev/mmcblk* .. but it will protest because its mounted Mar 23 23:22:29 faddah_ .. it would be safer from a uSD card boot :p but then I always get confused which mmcblk it is Mar 23 23:22:58 IT'S WORKING!!! So I was trying to compile VIA debian build and I noticed the mistake I was making was I did not comment out deb-src from the sources.list Mar 23 23:23:11 heh Mar 23 23:23:14 Therefor I could now download build-essentials :/ Mar 23 23:23:50 ah which nonce put 'deb-src' in the apt sources list .. that not a good idea on a limited-space system .. -facepalm- Mar 23 23:24:11 I have a 16 BG ssd installed Mar 23 23:24:14 *GB Mar 23 23:24:18 *SD Mar 23 23:24:23 blah typos Mar 23 23:24:44 brb one sec Mar 23 23:24:46 veremit & johnpaul - there's mmcblk0, mmcblk0boot0, mmcblk0boot1, mmcblk0p1, and mmcblk0p2. Mar 23 23:25:09 Okay, was switching clients :P Mar 23 23:25:33 faddah_ ignore all the 'boot' ones Mar 23 23:25:48 SpyKu .. does that -work- with the BBB?? Mar 23 23:26:02 Not bone. Beagleboard C5 Mar 23 23:26:06 ahh np Mar 23 23:26:29 it may be dusty but i'm trying to put it to use as a media server and tor relay :P Mar 23 23:27:01 veremit johnpaul - ok, won't allow mmcblk0 - "/dev/mmcblk0 is in use. e2fsck: Cannot continue, aborting." Mar 23 23:27:14 faddah_ exactly as I predicted :) Mar 23 23:27:37 veremit johnpaul - skipped the boot ones... Mar 23 23:27:38 SpyKu .. there's a kewl project for that kinda thing on the beagle iirc Mar 23 23:27:41 # fsck -f /dev/mmcblk0p1 fsck from util-linux 2.20.1 dosfsck 3.0.13, 30 Jun 2012, FAT32, LFN /dev/mmcblk0p1: 160 files, 36667/49047 clusters Mar 23 23:28:10 Was thinking about getting some high storage USB drives to expand memory. The prices have gone down alot Mar 23 23:28:41 veremit & johnpaul - and finally: "fsck -f /dev/mmcblk0p2 fsck from util-linux 2.20.1 e2fsck 1.42.5 (29-Jul-2012) /dev/mmcblk0p2 is mounted. e2fsck: Cannot continue, aborting." Mar 23 23:29:14 SpyKu .. FreedomBone Mar 23 23:29:19 :P Mar 23 23:29:31 veremit & johnpaul so... once again, how can i: a) restart the ssh daemon; b) restart the whole board (like gracefully shutting down & restarting any linux)? Mar 23 23:29:45 sudo service ssh restart Mar 23 23:29:55 ^ Mar 23 23:29:56 sudo reboot Mar 23 23:30:03 +1 spyku Mar 23 23:30:19 i'm learning fast :P Mar 23 23:30:27 SpyKu johnpaul veremit - ok, thank you Mar 23 23:30:48 SpyKu KotH veremit johnpaul - i don't need to sudo as i all ready am 'root' Mar 23 23:30:59 ok, the no "sudo" Mar 23 23:31:05 SpyKu KotH veremit johnpaul - at least i don't think i need to Mar 23 23:31:06 faddah_ .. doesn't matter :) Mar 23 23:31:23 but its our default suggestion lol not everyone logs in as root because of the potential for damage Mar 23 23:31:37 veremit - what do you log-in as? Mar 23 23:32:02 debian :) or my user Mar 23 23:32:09 depending on the platform Mar 23 23:32:22 but I often 'sudo su' to get root terminal Mar 23 23:32:23 password for debian? i've created no other user Mar 23 23:32:31 temppwd? Mar 23 23:32:31 debian:temppwd normally Mar 23 23:32:34 temppwd Mar 23 23:32:50 RCN's default .. and I've installed about 5 of his debian's now lol Mar 23 23:32:56 all but the Pi. Mar 23 23:33:07 RPi .. the BPi is running RN's debian Mar 23 23:33:21 And logging into your own user (or debian) is recommended, then using sudo su if you need to be root (recommended to only use if sudo commands don’t work) Mar 23 23:33:52 Yes. i once borked my ubuntu from logging in VIA root and messing around :/ Mar 23 23:34:03 however, sudo su -c will run the command as root and sudo su isn’t needed then :) Mar 23 23:34:07 johnpaul .. I saw a good trick on RN's pages about 'su -c "echo" ' if you need to write .. Mar 23 23:34:14 ... like that Mar 23 23:34:24 :) Yep Mar 23 23:34:41 You still need to preface su with sudo, however, I think. Mar 23 23:34:48 Ah, ok. I think it's compiling now. No more "apt-get ***" errors Mar 23 23:35:00 yes. Need to sudo su Mar 23 23:35:04 veremit, johnpaul & SpyKu - ok, successfully restarted ssh & rebooted board. is there a "shutdown" instead of "reboot" to bring the board down completely so i can unplug and try plugging it back in via regular USB, not debug cable, to see if it is working correctly now? Mar 23 23:35:18 sudo shutdown now -h ? Mar 23 23:35:45 Spyku johnpaul veremit - what's the '-h' for? Mar 23 23:35:49 halt Mar 23 23:35:49 faddah_: running sudo shutdown now will work fine Mar 23 23:36:07 faddah_ "shutdown -h now" or "halt" Mar 23 23:36:18 no difference between "-h" and regular sudo shutdown ? Mar 23 23:36:21 "-h" is for 'halt' "-r" for reboot Mar 23 23:36:55 but you can shortcut to simply "sudo halt" or "sudo reboot" or even "init 0" and "init 6" which do the same thing (not necessarily in that order) Mar 23 23:37:19 Hmm. I need to read some books on linux Mar 23 23:37:27 any suggestions? Mar 23 23:37:52 that did i, thank you, all (veremit, SpyKu, johnpaul) - replugging into regular usb, not debug cable Mar 23 23:38:29 SpyKu:There are tons of books, but if you look at topics that LPIC cover, its a really good start Mar 23 23:39:01 SpyKu: for example, lpic 101 and 102 have i think 10 chapters Mar 23 23:40:08 Ahh ok. Thanks for the suggestion :) Mar 23 23:40:53 SpyKu: I don’t have any of my certifications yet (and some argue that they are useless) but I do intend to get my LPIC certs :) Mar 23 23:41:46 SpyKu: I would argue that they are useless in the sense that it doesn’t prove what you know. but if you are job seeking, it is a buzzword for recruiters that see résumés. Mar 23 23:42:09 faddah_: all set? :) Mar 23 23:42:45 johnpaul SpyKu veremit KotH - ok!! can log back in via straight USB and ssh in as root. phew! Mar 23 23:43:01 veremit: http://www.linux.com/learn/tutorials/776799-servo-control-from-the-beaglebone-black — seems to be a nice start , but I’m not 100% convinced it is the best way of doing it Mar 23 23:43:22 faddah_: tadah! :) glad its working! Mar 23 23:43:50 now to see if i can bridge my internet from the Chromebook to the bbb - hang on. Mar 23 23:45:59 veremit: http://www.linux.com/learn/tutorials/776799-servo-control-from-the-beaglebone-black — seems to be a nice start , but I’m not 100% convinced it is the best way of doing it (sent before it said you disconnected) Mar 23 23:46:24 dratted machine rebooted lol Mar 23 23:49:42 johnpaul, veremit & SpyKu - almost, but i still can't get beagle to see outside Internet bridging from my Chromebook. but i have to go now too -- meetings in downtown portland. Mar 23 23:50:16 faddah_: Yea, that will be something that search Google may help wtih — I have never done a bridged conncetion with chromeos Mar 23 23:50:23 searching* Mar 23 23:50:42 faddah_ did you get usb networking back? Mar 23 23:50:54 veremit - yes Mar 23 23:50:59 veremit: faddah_ said that he could ssh via usb :P Mar 23 23:51:09 faddah_: (I said he, but idk if he or she) :P Mar 23 23:51:14 well that a start :) Mar 23 23:51:23 johnpaul veremit - i'm a he, it's ok Mar 23 23:51:33 good luck with bridging .. I'd recommend plugging it directly into your router ;) Mar 23 23:51:36 faddah_: haha okay Mar 23 23:52:24 veremit johnpaul - can i continue to plug it into my Chromebook & ssh into 192.168.7.2, _and_ also plug it into the router via ethernet? Mar 23 23:52:35 faddah_: definitely Mar 23 23:52:53 faddah_: you can run ‘ifconfig’ and you’ll see eth0 will get an ip from the router Mar 23 23:53:01 johnpaul & veremit - _both_ will work at the same time? Mar 23 23:53:05 faddah_: yes Mar 23 23:53:06 faddah_ yes Mar 23 23:53:41 ok, time for shower :) Mar 23 23:53:53 faddah_: I have had a USB, Eth, and Wireless connection and everything worked fine Mar 23 23:54:42 johnpaul - how'd you do wireless? a cape? Mar 23 23:54:57 faddah_: nope, a usb wi-fi adapter Mar 23 23:55:11 faddah_: there are a few that are supported, let me grab the link for the one i bought Mar 23 23:55:42 faddah_: http://www.amazon.com/gp/product/B004VDR37K/ Mar 23 23:57:47 faddah_: essentially, you can plug that in, modify your /etc/network/interfaces file, and you will have wi-fi Mar 23 23:58:09 johnpaul veremit SpyKu - ok, ethernet connected to router. ping, however, is not working. :( tried pinging google.com, nothing. Mar 23 23:58:26 faddah_: what does ifconfig say? Do you have an IP? Mar 23 23:58:35 faddah_: also, are the lights on and working? Mar 23 23:59:38 hang on - working now!! Mar 23 23:59:40 yay! Mar 23 23:59:50 woot Mar 24 00:00:20 ifconfig will give you the IP, you can disconnect the debug and usb network and ssh to the ethernet :) Mar 24 00:00:39 johnpaul veremit just wish i could bridge i-net from my Chromebook via usb and _not_ have this long-ass ethernet cable tether for my roommates to trip over Mar 24 00:00:49 faddah_: The only thing: IP address can change. Mar 24 00:01:00 faddah_ .. not gonna happen .. if you thouht debig was bad .. Mar 24 00:01:11 faddah_: I have a roommate that complained a little. I got the wi-fi because of that :) Mar 24 00:01:15 faddah_ .. go for wifi as per johnpaul ;) Mar 24 00:02:28 johnpaul veremit - got it. go for wifi mini Mar 24 00:02:35 faddah_: yep :P Mar 24 00:03:03 quick / random poll: where are you guys from? just curious haha. (I am in MI) Mar 24 00:03:12 NY Mar 24 00:03:21 -<= SW England, UK Mar 24 00:03:26 johnpaul veremit - the apt-get package, is it "buildessentials" or "buildessential"? i tried doing "sudo apt-cache search buildessential" but it ain't finding nuttin'. Mar 24 00:03:42 uncomment VIA sources.list Mar 24 00:03:56 <<== portland, oregon, u.s - same weather as UK. ;) Mar 24 00:03:59 deb-src Mar 24 00:04:11 and tis' build-essential Mar 24 00:05:10 SpyKu - thanks! it all ready had it, as turns out Mar 24 00:05:15 cool thanks - all spread out :P Mar 24 00:05:37 ok, now I shower! Mar 24 00:05:38 brb Mar 24 00:06:39 SpyKu, johnpaul & veremit - thanks much, all i'm now updating npm & node (want node at 0.10.36, it's at 0.10.25). very, very cool. i appreciate all the help and sloooooooowly hand-holding me through. Mar 24 00:06:50 and please thank KotH for me, also Mar 24 00:07:40 faddah_: you’re welcome, glad to help. it can be a little frustrating sometimes. It gets a little annoying trying to find info spread across 30 random internet pages :P Mar 24 00:08:14 johnpaul - truly, indeed. needs massive doc clean-up Mar 24 00:08:45 gonna go, but thank you to all of you. Mar 24 00:08:53 faddah_: and maybe a reorganization :) I am actually going to a Meetup this thurs, a co-founder is there :D Mar 24 00:09:08 faddah_: don’t think i can really say much, but i will ask. Mar 24 00:09:14 faddah_: and see ya later! glad its working Mar 24 00:10:01 johnpaul veremit SpyKu KotH - do tell the founder docs need MASSIVE overhaul and centralizing Mar 24 00:10:20 johnpaul veremit SpyKu KotH - thank you again to all. signing off for now. Mar 24 00:10:33 :) Mar 24 00:23:49 You know I should actually load an image into my BBB or at least try too... huh ... need cable to access console to do it right duh. Mar 24 00:29:19 GenTooMan .. well that's the easiest .. ;P Mar 24 00:31:32 I wanted to order 2 weeks ago.. .just keep forgetting too. Mar 24 00:32:48 lol GenTooMan Mar 24 00:34:40 ahh nice shower :) Mar 24 00:51:37 hi , i need help , someone have chipsee cape? Mar 24 00:52:32 luciano: just ask questions about the issue you're having, and maybe someone can respond... Mar 24 01:18:20 Hi I have a question where can I buy 1000 Beagle board at the lower price (Black bone) Mar 24 01:19:33 Pedro .. I don't think you'll find any stockists/vendors willing to sell you 1000 boards .. because they themselves don't have them. Mar 24 01:19:34 they're not really available in bulk, as far as i know Mar 24 01:19:51 you can take the designs and get them made, however. Mar 24 01:24:34 you might be able to order them from circuitco who produces the boards Mar 24 01:25:35 If you are planning to use them in a comercial product however you might consider using something like gumstix or the like instead as those have a longer support cycle. Mar 24 01:27:09 GenTooMan .. I'm not aware even CircuitCo have the capacity or would be interested, tbh. Hence the approval of a clone by element14 Mar 24 01:27:23 Thanks I will get in contact with circuitco Mar 24 01:30:09 Getting a large number made can be tricky but ask circuitco as they seem to be pretty helpful. They are a contract manufacturer primarily. Anyhow good fortune. Mar 24 01:31:30 I would be concerned getting a real of any of the IC's as the most expensive is the eMMC part then the SoC then again the SoC is cheaper than the processor I had to use for something (it's $50 in bulk). Mar 24 01:32:01 GenTooMan .. there are companies that can source silicon :) I've used one/two Mar 24 01:32:28 even here in the UK! Mar 24 01:32:56 usually sourcing via US or elsewhere Mar 24 01:33:38 AFK a few. Mar 24 02:14:48 !ping jkridner Mar 24 02:42:56 lolz **** ENDING LOGGING AT Tue Mar 24 02:59:58 2015
