**** BEGIN LOGGING AT Tue Jan 06 02:59:59 2015 Jan 06 03:11:44 hello Jan 06 04:09:30 has anyone here had any problems flashing to the emmc? Jan 06 04:09:42 i know the image works because i can boot from the sdcard, but when i try to flash it nothing happens Jan 06 04:09:51 i must have tried about 4 times now Jan 06 06:19:37 kl0wn: there are two images, one is an eMMC flasher the other is for booting straight off the SD card. are you sure u has the correct img Jan 06 06:21:56 hmm yes that could definitely be the issue, ive been trying to use the same image each time. I'll check right now, thank you very much j0rd_ :) Jan 06 06:42:06 kl0wn: nps Jan 06 06:48:11 haha that was it j0rd_ Jan 06 06:48:19 god damnit i'm such a clown :) Jan 06 06:48:28 thanks again! Jan 06 06:49:04 all good Jan 06 07:23:41 hay Jan 06 07:23:47 anyone have experience with PRU cape? Jan 06 08:01:17 I have installed debian OS on BBB but it does not open in windows and linux.. what problem here next what I do? Jan 06 08:01:38 open what? Jan 06 08:02:42 HALP Jan 06 08:04:04 palani what do you think should open in windows or linux? Jan 06 08:13:31 Hi there Jan 06 08:17:02 hi Jan 06 08:19:08 Could you please tell me whether Beaglebone/Beaglebone black is capable of running Linux for a very long time? Jan 06 08:19:50 I imagine it is, but I haven't tested yet as I got email telling me that my beaglebone black was shipped yesterday Jan 06 08:20:01 a sample application is remote system monitoring Jan 06 08:20:25 thanks Mikaela Jan 06 08:20:40 you're welcome Jan 06 08:20:52 has anyone come across such a documentation or a discussion in any forum? Jan 06 08:21:08 my raspberry says that it has been running for 83 days and beaglebone black shouldn't be too different Jan 06 08:22:27 oh that's great to hear Jan 06 08:22:30 thanks Jan 06 08:23:01 vaish if you do not rely on usb Jan 06 08:23:05 it will run a long time Jan 06 08:27:49 we would like to develop a remote monitoring controller and initially test the same on beaglebone black Jan 06 08:28:10 a remote monitoring controller is supposed to run for years Jan 06 08:28:53 +1 to woglinde Jan 06 08:28:57 we would be able to choose AM3359 if beaglebone black has proved to be efficient in this regard Jan 06 08:29:08 It you do not rely on usb, it would last longer Jan 06 08:31:39 thank you woglinde and dastaan Jan 06 08:32:15 which would be better for the above said requirement - Raspberry Pi or Beaglebone Black? Jan 06 08:32:33 I have a Rpi based logging system for my industrial unit. It's been running for almost a year. Not even a single problem Jan 06 08:33:03 that's awesome! Jan 06 08:33:18 I prefer BBB for embedded application as it's way powerful than Rpi. Jan 06 08:35:17 thanks for valuable suggestions Jan 06 08:35:52 Raspberry Pi just has the issue that it's not recommended to run normal Debian on it and it's difficult to upgrade Raspbian from one release to another. Jan 06 08:36:57 Again, it depends on the application. Here is a nice comparison. Jan 06 08:36:59 http://makezine.com/magazine/how-to-choose-the-right-platform-raspberry-pi-or-beaglebone-black/ Jan 06 08:37:09 I have some kind of need for another small computer and because of that decided to look for alternatives and Debian wiki said that beablebone black is supported and it also was listed as OSHW which I like to support. Jan 06 08:47:29 Mikaela: i was under the impression that you need a special kernel Jan 06 08:49:46 https://wiki.debian.org/RaspberryPi Jan 06 09:16:56 I have installed debian os on BBB. Now I connected using usb to computer.. this is windows 7.. but it not show the BBB drive.. what I do? Jan 06 09:17:48 anyone help me? Jan 06 09:22:20 Hi there Jan 06 09:22:51 Hi Mikaele/dastaan Jan 06 09:23:16 in continuation to the question I had asked sometime before Jan 06 09:23:36 which is better for a long time run - raspberry pi or beaglebone black Jan 06 09:23:55 can I use beagleboard xm for the same purpose Jan 06 09:24:21 hi Jan 06 09:24:23 if you replace the second e with a, I will get highlight and notice more easily. If you start typing nickname and press tab (above caps lock), it automatically completes the nick Jan 06 09:24:32 I don't have experience with beaglebone black yet Jan 06 09:25:14 sorry, that was a spelling mistake Jan 06 09:25:24 need some help , beagleboard xm stuck on logo (tried debian and ubuntu) on hdmi display.but amstrng is working properly Jan 06 09:25:29 any idea about bb-xm? Jan 06 09:26:00 the only microcomputer I know if Raspberry Pi Jan 06 09:26:11 I believe this should be equally good or even better than the other two Jan 06 09:26:18 until DHT gets here with the beaglebone black Jan 06 09:35:58 vaish_: for industrial applications a BBB (or rather a blue steel) makes sense, BBXM not so much. Jan 06 10:05:52 Does BeagleBone Black supports all type of USB cameras? Jan 06 10:09:49 if the camera is supported by the 3.8 kernel version that the board usually runs, then it will work. Jan 06 10:10:08 if it needs processing power, then you need to check if the CPU will have enough available Jan 06 10:15:56 so i have to check its supported kernel version and required power is it so? Jan 06 10:18:08 or you just plug it in and find out Jan 06 10:18:17 most devices are UVC nowadays anyway Jan 06 10:23:24 ok. thanks for your information tbr Jan 06 10:24:14 np Jan 06 10:29:46 I odered Logitech HD Webcam C270. I didn't know whether beagleboneblack supports it or not. thats why i asked Jan 06 10:36:13 greetings all Jan 06 10:37:50 am I reading correctly that usb is one of the supported boot options for the black? Jan 06 10:38:38 hmm I've had what *feels* like intermittent fault/flaky performance ssh-ing to my beaglebone black. Is it possible this is a cabling issue (too long usb cable from laptop to beaglebone) Jan 06 10:39:49 Tenkawa: you can't boot directly off mass storage if you are asking that Jan 06 10:40:01 rick-monster: any errors listed on ifconfig? Jan 06 10:40:13 tbr: usb you mean? since I know you can sd Jan 06 10:40:21 tenkawa - on the laptop or beaglebone? Jan 06 10:40:23 and sd is mass storage too Jan 06 10:40:27 Tenkawa: you can have your boot loader and kernel on eMMC or µSD and your rootfs on USB Jan 06 10:40:37 rick-monster: ahhh Jan 06 10:40:44 I'd check both Jan 06 10:41:15 Tenkawa: if there is nothing on eMMC and no µSD card connected, you can't "just plug in a USB stick and boot" Jan 06 10:41:20 well darn... wanted a quick way to clone this running bbb that only uses the emmc Jan 06 10:41:28 a straight ifconfig with no other options looks normal on the beaglebone, but doesn't register the interface at all on the laptop Jan 06 10:41:49 Tenkawa: there are scripts to clone the eMMC Jan 06 10:42:23 tbr: oh? do tell.. Jan 06 10:42:38 someone mentioned it here, I don't know more Jan 06 10:42:44 I've got a prepped emmc I need to clone many times Jan 06 10:42:51 ok.. Ill do some digging Jan 06 10:42:54 thanks Jan 06 10:42:55 I'd expect that you find something on the elinux wiki Jan 06 10:43:12 yeah I figured that was well Jan 06 10:43:43 has there been "any" mention of developing any more boards (beagle) lately? Jan 06 10:44:01 I really like these new bbb's I picked up Jan 06 10:44:17 I want to see more development on them continue personally Jan 06 10:44:35 there will be a successor to the BB XM soon. the X15 Jan 06 10:44:46 nice Jan 06 10:44:59 never picked up an xm though Jan 06 10:45:09 though I currently switched to a MinnowBoard for some things Jan 06 10:45:10 I've really been a headless server type Jan 06 10:45:33 tbr: got too many board variants here tp list Jan 06 10:45:38 er to Jan 06 10:46:22 got to try to figure out today if I have a shorted/blown out bbb board Jan 06 10:46:36 got one that wont do anything except flash one led Jan 06 10:47:09 if it won't boot off a known good µSD, then it's likely toast Jan 06 10:47:34 yeah I'm afraid of that too Jan 06 10:47:56 haahaa doh I'm being dense Jan 06 10:48:21 I can take this usb clone it to mmc cards and use those to boot back from Jan 06 10:48:26 hehehe Jan 06 10:48:32 (not 6 am yet here) Jan 06 10:55:53 at least now I have a cloning source hehehe Jan 06 10:59:57 now to see if there's any hope for that non responsive board Jan 06 11:00:16 or if I'll be picking up another new rev 4 Jan 06 11:00:37 (which the 4gb emmc update was huge for me) Jan 06 11:03:17 cheers all Jan 06 11:19:54 yep.. just tried half a dozen power up scenarios on the last unit. no dice Jan 06 11:20:10 wish i knew what blew on the board Jan 06 11:30:06 can the bbb be connected up as a dual mode usb device so I can access its storage only? Jan 06 11:33:21 experiment time hehehe Jan 06 11:59:47 Tenkawa: shared storage or export block device? Jan 06 16:27:00 Has anyone tried using the PowerVR GPU to accelerate image processing on the beaglebone black? Jan 06 16:27:49 the API is only OpenGLES, so it isn't so easy to do image processing with it. There has been some color conversion acceleration done in the past, but not packaged nicely. Jan 06 16:28:18 I was thinking of using GLSL shaders to accelerate some algorithms Jan 06 16:28:39 That would help in robotics where you have to detect colored objects Jan 06 16:29:31 So theoretically you could use the GPU to parallelize processing Jan 06 16:38:56 cool. I'd love to see it! Is GLSL included in GLES? Jan 06 16:39:15 * jkridner isn't so familiar and looks at https://www.khronos.org/opengles/sdk/docs/man31/ Jan 06 17:02:32 Can someone help me? I'm looking for some good, straight forward documentation on how to add devices to the device tree. Jan 06 17:03:34 What kind of device? Jan 06 17:07:57 jkridner: glsles is in gles2.0 Jan 06 17:09:06 not quite the same spec as glsl, but it is a somewhat similar shader language Jan 06 18:24:43 thurgood_: thanks Jan 06 18:58:44 buen dia se despegue mi adaptor de puerto serial (rs232) en la tarjeta como puedo mandar la para que se arreglar la good day my serial port adapter (rs232)is off the card as I can send to you to fix the Jan 06 19:00:01 Gesundheit Jan 06 19:14:15 john09: serial port on which device? Jan 06 19:16:40 hm what means of the card? Jan 06 19:20:39 the serial port the device Jan 06 19:20:45 want send for rma Jan 06 20:00:25 i m gonna use beagleboard first time , particularly beagleboard-xm Jan 06 20:01:10 confused about which programming language to use with Jan 06 20:01:49 what language are you most familiar with? Jan 06 20:02:07 java and c++ Jan 06 20:02:07 generally c/c++ is a good choice :P Jan 06 20:02:23 java is a little slower Jan 06 20:02:30 and what do you have in mind, what do you want to do with beagle? Jan 06 20:02:56 i m gonna use it for ECG purpose Jan 06 20:03:46 to measure and display ECG waveforms Jan 06 20:07:31 ymmv, but i might choose c/c++ for low level stuff, qt or perhaps java for higher level functions Jan 06 20:12:17 hi one query, is uart by default enabled in beaglebone black ? do i need to do some pin muxing to get it ? Jan 06 20:12:40 which uart? Jan 06 20:13:43 any uart is ok for me i need to do some communication with an external chip Jan 06 20:14:06 the ftdi port is active by default, but carries debug info on it Jan 06 20:14:47 so you want active and free? Jan 06 20:15:48 thurgood_: so you mean i should use a usb to uart cable to use the default port? Jan 06 20:16:44 *i mean usb to serial cable? Jan 06 20:16:52 no, although you/could/ do that Jan 06 20:17:37 assuming the cable has kernel support Jan 06 20:18:52 thurgood_: i dont need that as im short of the cable, im using debian , but are there some defaultuart rxd and txd lines directly brought to the headers which i don't need to do any pin muxing as such? Jan 06 20:19:55 do i need to make any device tree overlays to get txd and rxd pins on headers ? Jan 06 20:20:40 thurgood_: thanks for the support, or does it also depends on the wheezy releases? Jan 06 20:23:08 *now i go it, i actually dont need the debug info, but want a fresh uart rxd txd lines to do some external communication with a chip Jan 06 20:24:07 right , otherwise the console messages will interfere with the device's data Jan 06 20:24:42 I'm actually not sure how to do pinmuxing in the more recent kernels used with the bbb :/ Jan 06 20:25:17 you may need to alter the device tree stuff Jan 06 20:27:34 thurgood_: thank you for the help, will do it :) Jan 06 21:58:22 what are some good option for a remote control for Beaglebone Jan 06 22:56:48 do the beagle bone blacks have an accurate on-board clock? e.g., one that would remain accurate to within a second over a few weeks? Jan 06 23:05:40 yates: the crystal is specified to be +/- 30ppm I think, which is +/-78 seconds per 30 days Jan 06 23:06:04 it might be +/- 60ppm, which would double that Jan 06 23:07:26 looks like mine is around 40-41ppm, based on the temperature (26C-22C) Jan 06 23:07:55 ddrown: thanks - good to know! Jan 06 23:09:41 yates: bonus graph - change in clock speed at a given temperature: http://dan.drown.org/bbb/run9/tempcomp.conf.png Jan 06 23:12:49 man, that is accurate! Jan 06 23:13:15 those are just releative changes, not absolute numbers Jan 06 23:13:20 oh. Jan 06 23:13:34 "change in clock speed" Jan 06 23:15:30 I'm using it to reduce the impact of temperature change has on the local clock - http://dan.drown.org/bbb/run9/tempcomp.png Jan 06 23:16:04 does debian do a ntpdate sync when it boots? Jan 06 23:16:07 the red line is the movement of the temperature compensation software, the green line is the remaining error left over Jan 06 23:17:25 yates: I see a /etc/network/if-up.d/ntpdate Jan 06 23:17:32 which suggests yes Jan 06 23:18:58 so everytime the network is brought up, which would include at boot time? Jan 06 23:19:13 I think so Jan 06 23:19:18 thanks ! Jan 06 23:19:22 looking at my /var/log/messages, it seems that's true Jan 06 23:19:31 very good. **** BEGIN LOGGING AT Tue Jan 06 23:21:19 2015 Jan 06 23:24:16 is there something i could have done on the bbb to disable the usb interface? Jan 06 23:24:52 (accidently) Jan 06 23:25:14 is the usb interface brought up with some of the scripts referred to in /boot/uEnv.txt Jan 06 23:25:15 ? Jan 06 23:25:28 i edited that to disable cape signals. Jan 06 23:28:28 I have no idea. All I know about it is it comes from the kernel module g_multi Jan 06 23:28:40 and I don't think it's related to the cape manager Jan 06 23:30:28 I'm looking for a TI Pin Mux Utility Design file for the BeagleBone Black. Does anyone have one? I would rather not build one if it already exists. Jan 06 23:31:09 abferm: https://github.com/bradfa/beaglebone_pinmux_tables Jan 06 23:32:06 also nice PDF form - https://github.com/derekmolloy/boneDeviceTree/tree/master/docs Jan 06 23:34:18 ok, thanks ddrown Jan 06 23:34:22 I'm trying to use the TI utility to plan out my pin muxes and don't want to conflict with devices on the main board. A list of the possible muxes doesn't tell me what is already used. Jan 06 23:35:09 the PDFs have notes like "Allocated (Group: nxp_hdmi_bonelt_pins)" Jan 06 23:35:32 and "Used on Board (Group: pinmux_emmc2_pins)" Jan 06 23:43:39 Okay, I guess I'll use those to generate the file my self. Thank you. Jan 06 23:45:22 hello guys, I am trying to change the MAC address for the BBB. I am running a custom board. for the beaglebone i have found https://groups.google.com/forum/#!topic/beagleboard/J-5mDkI8p0Q but is not used anymore. Jan 06 23:45:26 any hints ? Jan 06 23:48:26 vvu: you can set it after boot in /etc/network/interfaces Jan 06 23:48:44 yes but i want it beforehand Jan 06 23:48:53 i want to have it applied when the kernel boots Jan 06 23:48:54 ah Jan 06 23:56:39 can't you just set it /etc/network/interfaces first, then reboot? Jan 06 23:57:21 good quesiton - i need to do the same! Jan 06 23:57:30 i need to change it multiple times, i want to save it into eeprom then read it from the kernel at bootup Jan 06 23:58:20 also, how do you know what mac addresses are available when setting a mac address? Jan 06 23:58:30 i.e., so you don't clash with some existing network interface. Jan 06 23:58:46 we control inside every mac address for our boards. Jan 06 23:59:14 vvu: couldn't you write a script that pulls it out of eprom and writes it into /etc/network/interrfaces at an early boot state? Jan 06 23:59:33 vvu: yes, but what about other devices on your network? printers, pcs, etc? Jan 07 00:00:30 i think the company has a mac address space unique. Jan 07 00:00:36 ah. Jan 07 00:01:05 as i know on the old beaglebone the mac address was 1st read from the am335x regs or something like that. if that mac address was valid it was applied otherwise it would try to read it from the eeprom. Jan 07 00:01:09 found some old blog post about this Jan 07 00:01:15 but for the bbb no sign of this Jan 07 00:01:48 ddrown: how do i insert a kernel module - looks like you're absolutely right - g_multi is not present (using lsmod). i've tried modprobe with and without full pathname and i get "...g_ulti.ko Jan 07 00:01:58 ... g_multi.ko not found" Jan 07 00:03:00 is it compiled as a module 1st of all ? Jan 07 00:03:40 i thought everything under /lib/modules were kernel modules. no? Jan 07 00:04:13 /lib/modules/3.8.13-bone64/kernel/drivers/usb/gadget/g_multi.ko Jan 07 00:04:32 i just tried with insmod and get "Invalid parameters" Jan 07 00:09:13 yates: found this https://groups.google.com/forum/#!topic/beagleboard/J-5mDkI8p0Q Jan 07 00:09:22 the values in the am335x regs are read only Jan 07 00:24:43 any idea how kernel modules get loaded at boot time? Jan 07 01:12:21 hi all Jan 07 01:12:55 whats new? **** ENDING LOGGING AT Wed Jan 07 02:59:58 2015
