**** BEGIN LOGGING AT Thu Jul 16 02:59:59 2015 Jul 16 13:36:49 hi Jul 16 13:44:20 Hello, I'm having a hard time getting a python wrapper to compile on the BBB. I'd appreciate some advice as I'm stuck: http://pastebin.com/3JtwmB0N Jul 16 13:47:56 SmileGuy you need the hardfloat version Jul 16 13:48:27 and file is not enought Jul 16 13:48:35 to determine the float stuff Jul 16 13:48:45 you need readelf or nm for it Jul 16 13:48:58 Ok thank you I'll try that right now. Jul 16 13:49:11 http://www.cnx-software.com/2013/04/22/how-to-detect-if-an-arm-elf-binary-is-hard-float-armhf-or-soft-float-armel/ Jul 16 14:03:34 woglinde: Thank you!! It worked!!! :D Jul 16 14:04:12 fine Jul 16 17:11:49 I have a system that I want to power off after an amount of time and the only access I have to it is through ssh. What files do I need to edit to make that happen? Jul 16 17:12:14 Technicus, cron? Jul 16 17:12:32 cron works :) used it before. Jul 16 17:12:48 although not yet with a timeout ... Jul 16 17:13:02 or "sleep xyz ; halt;" ;) Jul 16 17:13:04 veremit: will you tell me what you did? Jul 16 17:13:33 open up /etc/crontab .. its all there. Jul 16 17:13:37 I want the system to turn off if there is no user activity. Jul 16 17:14:02 Technicus, then cron isn't good for that. ;) Jul 16 17:14:11 you can use 'halt' or I was old-skool and wrote out the full 'shutdown -h now' lol .. but you can substitute the 'now' ... Man shutdown. Jul 16 17:15:51 I would just use the lxde powermanagement settings, but I have a lcd cape connected and I can't see all the gui. Jul 16 17:15:58 Where is the config file for it? Jul 16 17:23:08 I'll defer on this one .. cos I'm onl using xfce or kde Jul 16 17:23:30 I'd personally change my screen reso.... oh wait .. plug a monitor in ;P Jul 16 17:24:13 anyone running with 4.x kernel? i tried upgrading the other day from 3.14, but it won't make it past 'Starting kernel...' (i can't ssh either, so it doesn't appear to be a tty issue) Jul 16 17:24:14 its unlikely to work very well .. gauging user vs system activity is not a precise art. Jul 16 17:24:17 I can't get the hdmi out. Jul 16 17:25:14 cc0_ do you have serial debug available? you may be lucky enough that logging started in /var/log .. if not its harder to diagnose Jul 16 17:25:49 cc0_, even the serial log shoud help ;) Jul 16 17:26:35 yeah, i'm watching the u-boot logs over serial Jul 16 17:26:47 if you pastebin it, i'll look.. Jul 16 17:27:11 now there's an offer .. ;P Jul 16 17:27:27 awesome, thanks rcn-ee Jul 16 17:28:50 http://processors.wiki.ti.com/index.php/Kernel_-_Common_Problems_Booting_Linux#Problem_.231_-_No_more_output_is_seen_on_the_console_after_.22Starting_Kernel....22 TI says potential tty mismatch, but these docs may be outdated Jul 16 17:31:15 cc0_, in our 4.1 we have the change "ttyOx -> ttySx" so kernel messages will get dumped enabled... Jul 16 17:40:17 ti's docs probably stil on 3.8 Jul 16 17:40:24 or before :D Jul 16 17:41:36 those doc's shouldn't apply anymore, as we've returned to "ttyS" ;) (those docs where for ttyS -> ttyO) Jul 16 17:44:57 rcn-ee: will you be around later tonight? i foolishly unplugged my ftdi cable at home and now can't watch the u-boot logs from work Jul 16 17:45:31 i'm always around somwhere Jul 16 17:46:27 always?! :p Jul 16 17:47:08 of course, my ai's been uploaded to the bbb image. ;) Jul 16 17:47:15 lol Jul 16 17:47:22 about time :P lool Jul 16 17:47:29 specially with the 4.1.x skynet kernel.. Jul 16 17:49:09 my revB must be resisting assimilation.. Jul 16 17:49:44 I really should get another bbb .. Jul 16 18:34:55 hi guys I needed to see about having some led's be controlled by my beaglebone black. Long story short I have a rc car powered by my beaglebone black and I need/want to be able to turn led's on and off that will be placed in areas such as headlights and breaks. I have the beaglebone black powered by a 5 volt power source and was wondering how I could also power the leds from this source and turn them on and off from Jul 16 18:34:55 the beaglebone black? Jul 16 18:36:17 you'll need some transistors/or arrays to use the beagle ios to switch the 5v and resistors to limit the current to the leds. Jul 16 18:40:02 veremit, any examples you could suggest as far as wiring diagram is concerned? I am still a noob when it comes to resistors etc. but i can follow instructions Jul 16 18:42:49 principle as .. http://www.thebrokendesk.com/post/blinking-an-led-with-the-beaglebone-black/ Jul 16 18:43:03 there are a few variations, eg. with mosfet instead Jul 16 18:45:05 as usual .. the web fails me :/ Jul 16 18:46:03 veremit, well thats enough to get me started. I figure I can get some headlights and brake lights going with that information. Jul 16 18:46:24 hopefully :) its not the way I'd do it .. but its pretty close :) Jul 16 18:46:37 many ways to skin a cat, and all that! Jul 16 18:46:46 ok must mow the grass .. bbiab Jul 16 19:03:22 :-) I help some co-workers get started with the BBB today Jul 16 19:03:30 Er I get to help Jul 17 01:05:03 http://pastebin.com/n6QrNHig looks like rcn-ee isn't here anymore, but here is the log of my failing 4.1.1 boot Jul 17 01:05:30 maybe someone else might know what is going on? Jul 17 01:23:24 well, nothing in that log is a failure, Jul 17 01:25:14 so if that's the last you hear from the system, one possibility may be a wrong console setting in the kernel cmdline Jul 17 01:26:17 normally u-boot prints out the cmdline though Jul 17 01:32:17 what u-boot are you using? since it seems to be printing out a rather different set of messages than the one on my BBBs (which is from a reasonably recent rcn-ee image) Jul 17 01:32:59 here's for example what I get during boot: http://pastebin.com/ynLaCxLm Jul 17 01:35:09 note the remark about the console option... depending on kernel config it will either prefer ttyS0 and complain about ttyO0 but work nonetheless, or it will require ttyO0 and fail if you use ttyS0 Jul 17 01:35:22 (that's why I ignore the warning and leave it at ttyO0) Jul 17 02:05:53 check /dev/console exists (which it should) and that the root partition filesystem is supported in your kernel, and specified correclty on the kernel command-line Jul 17 02:56:27 lol, on thedailywtf a function which removes all elements satisfying some predicate from a singly linked list of elements which manages to be O(n^3) rather than O(n) Jul 17 02:58:20 pretty impressive **** ENDING LOGGING AT Fri Jul 17 02:59:58 2015
