**** BEGIN LOGGING AT Tue Jun 17 02:59:58 2014 Jun 17 04:03:44 So the website says all the lights should be solid after flashing... What do when no lights are on at all? Jun 17 04:05:24 SugarAddict: if no lights come on at all, then the card was prepared wrong Jun 17 04:05:33 actually Jun 17 04:05:39 recent images turn off after i think Jun 17 04:05:44 so no flashing at all is bad Jun 17 04:05:55 if you come back after 10 mins and it’s no lights Jun 17 04:05:57 then maybe ok Jun 17 04:09:13 isn't that only true for the new debian image? Jun 17 06:23:58 yay Jun 17 06:24:01 my BBB shipped Jun 17 06:24:03 booyah Jun 17 06:24:20 i'm a lucky boy Jun 17 11:19:30 how fast can i read GPIO on the BBB without using the PRU? Jun 17 11:22:28 treeherder: depends if userspace or kernel. Jun 17 11:23:21 tbr from kernel? Jun 17 11:23:36 could you give me an estimate on either? Jun 17 11:23:44 no, as I've never done that Jun 17 11:23:55 lol oh thanks though Jun 17 11:23:56 I just know that kernel is more reliable Jun 17 11:56:04 Hi... I'm looking for informations about avaliability of beagleboard-xm... I've trying to buy it but in every place i've looked there is no board avaliable... Anyone know when and if BB-XM will be avaliable again? Jun 17 11:56:25 (I looked at mouser, digikey, farnell etc) Jun 17 11:58:04 hmm is the BBxm still a thing? most things have been revolving around the BBB recently Jun 17 12:01:11 @tbr the problem is that we begun our project with bb-xm... It will be costly to change to BBB... Jun 17 12:09:13 project as in commercial product? Jun 17 12:58:23 hey there i'm looking for a good company in the UK to get some beagle boards from, the farnell website is down, can anyone give me a heads up? Jun 17 12:59:29 why not wait for farnell to be back up? Jun 17 13:00:04 http://uk.rs-online.com/web/p/processor-microcontroller-development-kits/7753805/ Jun 17 13:00:28 http://robosavvy.com/store/product_info.php/products_id/3910 Jun 17 13:00:37 https://www.google.com/search?q=beaglebone+buy+uk Jun 17 13:22:01 hi everybody ! Jun 17 13:23:06 happy? Jun 17 13:24:42 I am at present in vacancy and I would want to take advantage of it to compare miscellaneous real-time operating systeme on my BBB Jun 17 13:24:57 like linux-RT, Xenomai, FreeRTOS ... Jun 17 13:25:05 yes fine do it Jun 17 13:25:48 but i new in the mebedded world and my english sucks ( I'm french) Jun 17 13:26:20 Anybody already has to work above ? Jun 17 13:26:22 yes not a good basis to start with Jun 17 13:26:30 I am not Jun 17 13:27:26 trigger__: some people might have Jun 17 13:27:36 but asking a quesition like this is not much help Jun 17 13:27:38 I work normally with LinuxRT on x86 board but with ARM board it's more difficult Jun 17 13:27:47 so anyone want to suggest a noob friendly method of using the gpio pins and the pwm pins to operate a servo? I need to control a motor from an rc car and a servo for steering. I also want to do this through c++ Jun 17 13:27:48 you can get answers to specific questions here Jun 17 13:28:07 im also coming from the arduino world unfortunately Jun 17 13:28:08 for unspecific ones, googling and reading helps more Jun 17 13:29:44 Yeah i have find some help with google but i don't know how start :S Jun 17 13:30:00 but thx i go back to ask google :) Jun 17 13:30:18 alors: https://www.google.com/search?q=xenomai+beaglebone Jun 17 13:58:03 HI Jun 17 14:02:12 I have a problem with flashing my BBB and did not find any answer by googling. So i decided to go here and ask you. I've flashed my BBB about three times. I wanted to flash it again and now (after inserting a prepared sd card and pressing user/boot on startup), the BBB stops working after about 5 seconds and flashes the 4 LEDs like a larson scanner (or like KID from Knight Rider). Did I brick my BBB? Starting Linux from the SD card (o Jun 17 14:04:49 you cant brick it Jun 17 14:05:30 not with software Jun 17 14:07:08 with a brick Jun 17 14:08:25 this was what i hoped. but what does this larson scanner led code mean? Jun 17 14:08:44 that the flasher is doing something Jun 17 14:10:16 ah, you mean this larson blinking continues until the flashing is completed? It did not look like this the first three times i flashed the BBB. Jun 17 14:12:15 It was more like LED1(sd card) and LED3(eMMC) were blinking simultaneously while LED0 was blinking like a harbeat and LED2(CPU) flashed from time to time. Jun 17 15:23:43 hello everyone. Jun 17 15:24:20 i'm using beaglebone black fo the first time nd did the example of lights blinking given on the website Jun 17 15:24:31 now i don't know how to carry forward Jun 17 15:24:42 can anyone plz help me ? Jun 17 15:25:28 i need to know how to attach it to other hardwares and from where shall i program it ?? Jun 17 15:25:37 do i have to use cloud9 only ? Jun 17 15:25:58 it's basically a linux computer Jun 17 15:26:16 what are you trying to do / learn? Jun 17 15:26:18 computer ?? Jun 17 15:26:40 i connected it to my mac and intalled hardwares Jun 17 15:27:05 and did examples of lights blinking given on website of beagle bone Jun 17 15:27:13 you said that already, yes Jun 17 15:27:41 now i need to know that how can i connect it to input and output and get response ? Jun 17 15:28:09 to what input and output? Jun 17 16:17:43 Hello all.. Jun 17 16:19:15 Got an issue maybe someone can help me with. When I start my Beaglebone Black Rev C it boots fine runs for about 5 or 7 min then for some reason it executes the system Halt command and just goes down to power off. It's just like someone pushed the Power button or entered halt at the command line Jun 17 16:19:28 Has anyone see that before? Jun 17 16:26:09 how are you powering? Jun 17 16:27:56 Have tried Both a Powered USB Hub and a Standalone Power Supply that says it's 5Volts 1.2a Jun 17 16:28:13 Powering though the USB connector in both cases. Jun 17 16:28:50 this is all I see: Jun 17 16:28:51 Broadcast message from root@beaglebone (Tue Jun 17 16:21:37 2014): The system is going down for system halt NOW! Jun 17 16:29:16 and in /var/log/messages it just says System Going down for system halt. Jun 17 16:29:25 anything else in the message log ahead of that? Jun 17 16:29:35 Not that I can see. Jun 17 16:29:44 Do you have add-on hardware attached? Jun 17 16:30:04 un 17 16:05:34 beaglebone kernel: [ 257.279560] EXT4-fs (mmcblk1p2): mounted filesystem with ordered data mode. Opts: (null) Jun 17 16:11:01 beaglebone shutdown[2654]: shutting down for system halt J Jun 17 16:30:11 * jkridner wonders if the button is having some issue. Jun 17 16:30:22 any chance you can put a scope probe on the button? Jun 17 16:30:26 It might but it seems to be a fixed amount of time. Jun 17 16:30:42 Scope probe no :( Jun 17 16:30:47 hmmm.... using the pre-installed image? Jun 17 16:30:55 I wonder if you have the flasher image running. Jun 17 16:31:04 that would try to perform the flashing and then shut down. Jun 17 16:31:38 I've heard a report that a 'bone with both usb and 5v jack power sometimes triggers a shutdown when the 5v is unplugged Jun 17 16:32:06 meaning a loose connection on 5v might cause something like what you're seeing Jun 17 16:32:15 not maybe the most likely cause, but... Jun 17 16:32:40 It's curious. These are the same power bricks I have used for a couple of Pi's. Jun 17 16:34:06 when I look though the system log the halts are almost always 5min after the last message in the log Jun 17 16:59:40 jkridner you mentioned something about the Flash Image? I downloaded the debian image from the website and burned it on to a 8gig sd card. then booted that as I didn't want to disturbe the internal image. Jun 17 17:00:10 I booted off the internal image and the system is running fine for over 30 min .. Jun 17 17:00:39 Can you not boot the from the external SD card and leave it running? Must you flash it to the internal ? Jun 17 17:06:54 Kleewyc: which image did you download? Jun 17 17:07:08 one image flashes the on-board eMMC and the other doesn't. Jun 17 17:07:33 Yup. I have my eMMc turned off Jun 17 17:07:58 YES!!! DUH!!!! Jun 17 17:08:08 I see now.... it's all obvious.. Jun 17 17:08:54 There's two images... one that says eMMC which I downloaded and one that doesn't. Jun 17 17:09:09 ahhh first Newbee test I failed!!!! Jun 17 17:30:04 <__butch__> Kleewyc: I had that same problem. I was using the flasher image. Jun 17 18:46:52 howdy all Jun 17 18:51:45 ? Jun 17 19:01:37 moo! Jun 17 19:35:30 hello - i was hoping to ask a question about beaglebone and a DB25 port for cnc... is there anyone who knows a little about that here? Jun 17 19:38:47 dammit Jun 17 19:39:15 j6m: I could help you, but you left already. Jun 17 20:08:41 Hello...Iam trying to learn how to build a LabelDispenser and for that i need to read the speed off the conveyer that hold the items i will put labels on so i can tell the dispenser how fast it have to put on the label... Jun 17 20:09:27 does the conveyor have an encoder? Jun 17 20:10:01 i have tryed to hook up a 2000 pulse roatary encoder to a arduino mega but it seems to slow Jun 17 20:10:34 2000 pulses per rotation or second? Jun 17 20:11:04 I knew that arduino was slow :) Jun 17 20:12:01 2000 pr roatation Jun 17 20:12:14 and how many rotations per s? Jun 17 20:12:15 what's the RPM of the motor? Jun 17 20:12:53 2000 is awfully exact if you're just trying to estimate timing. Jun 17 20:13:45 yes arduino its slow and now i need a new controller and bbb seems way better Jun 17 20:14:38 BBB and AVRs solve different problems Jun 17 20:15:33 If it were me, I would probably try to find a less accurate encoder Jun 17 20:16:43 the two realtime procs on the BBB could help keeping up with the encoder? Jun 17 20:17:05 I am coming from messing with arduino's myself and have been trying to figure out how to use pwm to operate a servo off of pot values that will be sent to the beaglebone black. but cant find much for using the beaglebone black in this manner. Is there anything one can suggest when it comes to pwm on the beaglebone black and operating a servo? Jun 17 20:18:43 ok the one i got is used on herma dispensers but i don't need that mutch accuraty Jun 17 20:18:53 <_av500_> https://www.google.com/search?q=beaglebone+black+servo Jun 17 20:20:09 <_av500_> https://www.google.com/search?q=beaglebone+black+rotary+encoder Jun 17 20:28:30 Can I program my BBBRevC from Fedora? Or must it be a windows machine? Jun 17 20:31:04 windows machine? what do you mean program? Jun 17 20:31:35 nothing you can do on a windows machine with the bbb that I can think of that can't be done better from a linux host Jun 17 20:32:20 Current my new BBBrC is usb connected to my Fedora box: I want to copy the current base image to MicroSD for backup before I start Jun 17 20:33:46 My system did not come with an micorSD, so I bought one at the local camera shp Jun 17 20:34:39 So how do I copy the current image to the microSD using fedora? Jun 17 20:35:29 Lee_, what would be the point of that when you can always download a flasher image for debian? Jun 17 20:36:08 are you planning on booting from the emmc and overwriting whats on it? Jun 17 20:37:52 dd to the sd? Jun 17 20:38:54 Our project requires the ability to upload an entire new image with our configuration and software as an image; just wanted a base image to start from... Jun 17 20:39:20 what thurgood said Jun 17 20:39:27 not sure what you mean by eemc..im new to BBB Jun 17 20:39:39 emmc = internal storage Jun 17 20:39:41 er.. emmc Jun 17 20:40:07 ok..possibly..not sure i need that yet.. Jun 17 20:40:32 just wanted a base image ..incase its gets bricked Jun 17 20:40:33 eMMC is the onboard memory for non-volatile storage Jun 17 20:40:41 gotcha Jun 17 20:40:52 it woun't get bricked unless you short some pins Jun 17 20:41:21 so I simply need a safty precation.. Jun 17 20:41:22 sorry reading.... thanks for the ideas... i vill order a bbb and se if i can interact with the encoder igot already.... reading http://nathanielrlewis.com/?p=87 think its a good place to start Jun 17 20:43:34 So I read: "Board can be booted from SD using device ROM, so you can't "brick" it" but that assumes one has an SD card with something on it, right? Jun 17 20:44:03 of course Jun 17 20:44:32 So how do I put what is "essential" on the SD card to begin with? Jun 17 20:45:47 xzcat XXX.img.xz | sudo dd of=/dev/sdX Jun 17 20:45:51 is it that simple? Jun 17 20:47:22 unxz xxx.img.xz then dd if=xxx.img of=/dev/sdx Jun 17 20:49:12 ok..will give that a shot.. thanks Jun 17 20:49:33 <_av500_> upload remotely? Jun 17 20:49:36 <_av500_> unattended? Jun 17 20:49:49 <_av500_> then you need to think about recovery in case something goes wrong Jun 17 20:50:02 <_av500_> and it gets complicated Jun 17 20:50:35 yes..eventually a simple way for customer.. but for now..a method just in the lab. Jun 17 20:50:47 not remote Jun 17 20:51:28 <_av500_> well, for the lab, just boot from SD and ignore emmc Jun 17 20:51:32 <_av500_> plug a new card, done Jun 17 20:53:20 my SD is blank... Jun 17 20:53:34 I need to put an image on it! Jun 17 20:54:03 <_av500_> true Jun 17 21:24:53 Hi people! Should it be possible to use two contiguos PWM pins at the same time? (for example, P9_29 and P9_31) Jun 17 21:29:23 mistawright: i don't know that unxz foo.img.xz ; dd if=foo.img.xz of=/dev/sdX is going to be any better than xzcat foo.img.xz | dd of=/dev/sdX if you have a reasonably fast processor Jun 17 21:29:36 also depends on your disk speed Jun 17 21:29:57 * vagrantc prefers xzcat Jun 17 21:38:01 aleandros .. depending on how the PWM unit(s) are configured .. you can have multiple PWM's or complimentary PWMs for driving eg. H-bridges. Jun 17 21:42:57 I can't figure out why I can't see this I2C. There's only one device on the detect and when I unplug my I2C device it doesn't go away so I think that's something else. Jun 17 22:33:39 Hi all. I'm running Debian on my BBB (A5C). Are there OpenGL drivers for the chipset? Jun 17 22:34:43 you What?! Jun 17 22:40:55 veremit: That at me? Jun 17 22:42:25 why would there be OpenGL drivers for a specialised graphics chipset? Jun 17 22:42:41 its not a 'radeon' or a 'nvidia' lol Jun 17 22:45:27 The AM3358 that powers the BBB is an IC thats a collection of ICs that work together. The only difference is they're house within the same IC Jun 17 22:46:27 that said .. I know there were some hardware accelerated drivers done .. but I've been working with both beagle and wandboard lately.. and can't remember which one was progressing :D Jun 17 22:50:11 I've read the TI's latest EZSDK compiles with 3.8 kernels Jun 17 22:53:26 TI are slowly migrating towards mainline Jun 17 22:53:33 but graphics may be stalled at 3.8 Jun 17 22:54:09 unaccelerated framebuffer works in mainline 3.14.x on the BBB Jun 17 23:07:13 any recommendations on a gui toolkit to develop touch ui for a BBB with attached touchscreen Jun 17 23:07:16 just go qt? Jun 17 23:12:56 we use wx .. with glade you got a fairly easy designer Jun 17 23:18:52 I was going to do that with Qt, myself, but I dunno if that's the best idea Jun 17 23:19:11 I think Qt embedded can run on the framebuffer without needing X, but I might be wrong Jun 17 23:19:19 I don't think wx or Gtk can do that though Jun 17 23:20:36 I wanna learn PyQt :) Jun 17 23:20:54 I'd generally err towards PySide, not PyQt Jun 17 23:20:57 due to licensing Jun 17 23:22:41 pyside? Jun 17 23:24:48 it's another Python Qt binding Jun 17 23:25:13 I'll plead ignorance .. I've seen lots of PyQt around .. but dont know what it is actually :) Jun 18 00:28:16 I just got my black and when I connect with USB I can access it as a drive but cannot connect to 192.168.7.2. I am using win 8 and ubuntu 14.04 and followed all of the getting started instructions. If I connect with my win 7 machine everything works, but it tells me there's a problem with the drive when I first connect and asks me to scan/repair. Anyone seen this before? Please help.? Jun 18 01:06:06 does the bbb supply power on its usb output? Jun 18 01:06:32 if it is being power via the usb input? Jun 18 01:06:39 *being powered Jun 18 01:07:42 by the usb spec, yes .. but don't expect it to work if it's connected to a device :p the whole lot is likely to fall over Jun 18 01:09:02 well the device just isn't powering Jun 18 01:09:05 veremit: thanks. Jun 18 01:09:15 works fine on my desktop Jun 18 01:09:35 plug power in the DC jack Jun 18 01:09:40 righto Jun 18 01:09:42 thanks Jun 18 01:09:53 its really not designed to work from the usb mini-B alone **** ENDING LOGGING AT Wed Jun 18 02:59:58 2014
