**** BEGIN LOGGING AT Fri Dec 19 02:59:59 2014 Dec 19 03:01:53 sorry to ask this again: What version of linux has the most stable USB drivers? Dec 19 03:02:47 I am repeatedly starting a process that opens /dev/ttyACM0 to an Arduino Due and the USB connection resets ~every half hour Dec 19 03:04:01 go with ubuntu Dec 19 03:04:17 what kernel version do they use? Dec 19 03:04:25 (sorry that's what I meant by linux) Dec 19 03:07:20 py0 i'm trying boot of the sd but i dont think something compiled for arm 6 will run on arm 7 Dec 19 03:13:49 I can run fbsd on the sd Dec 19 03:14:10 i just try to boot up Dec 19 03:14:17 tryed Dec 19 03:14:26 ya dun fucked up somewhere bub Dec 19 03:14:33 because I'm borderline retarded and I could do it Dec 19 03:15:47 you didn't just type tryed instead of tried... Dec 19 03:16:11 what did you do by the way Dec 19 03:20:36 extracted img, used adafruit micro sd reader/writer, used dmesg to locate microsd, used dd on img w/ sd Dec 19 03:26:41 okay? i dont see why mine didn't work. i just flashed it Dec 19 03:31:36 i let the laptop die... Dec 19 04:41:40 Is it intended that one generally run as root for hardware projects? I made myself a regular user when I started, and found that it was really hard to toggle devicetree stuff, and now I pretty much just use root. I'm not cotrolling a server or anything (not internet connected at all, no wireless) Dec 19 05:10:28 on most embedded linuxes there's usually a no-password user who has permissions to all the groups that do The Fun Stuff that root would otherwise need Dec 19 05:10:52 i think also mint does that too, maybe some other desktop distros. Dec 19 09:13:40 <_av500_> security is hard, let's go making Dec 19 09:26:39 hi Dec 19 09:27:03 can anybody help me CRO interfacing of BBB Dec 19 09:27:37 I mean I want to display a sine wave on CRO using BBB Dec 19 09:28:00 <_av500_> CRO? Dec 19 09:28:09 <_av500_> C3RO? Dec 19 09:28:15 yes cathod ray oscillscope Dec 19 09:28:20 <_av500_> ah Dec 19 09:28:35 <_av500_> do you need DC? Dec 19 09:28:48 DC? or DAC? Dec 19 09:28:59 digital to analog converter Dec 19 09:29:27 <_av500_> no, do you need DC values to be shown Dec 19 09:29:32 <_av500_> 0Hz Dec 19 09:29:41 <_av500_> if not, you can use a simple USB DAC Dec 19 09:29:48 <_av500_> and output sound Dec 19 09:31:02 no no I just want to display a sine wave ...I will give input frequency to program and I want to output the sine wave on CRO Dec 19 09:31:08 no sound Dec 19 09:32:18 what is a USB DAC how will I output a sine wave using usb DAC any documents ? Dec 19 09:32:39 <_av500_> are you aware that sound is made from sine waves? Dec 19 09:33:05 _av500_: inconceivable! Dec 19 09:33:24 yes yes i know about sound Dec 19 09:33:43 <_av500_> so, you can generate a sinewave Dec 19 09:33:49 <_av500_> and output that Dec 19 09:34:11 how am I gonna display it to Cathod ray oscilloscope Dec 19 09:34:28 <_av500_> you connect output of USB DAC to input of CRO Dec 19 09:35:56 where can I get this USB DAC? Dec 19 09:36:28 and what are commands to output signals using this or any interfacing diagram Dec 19 09:36:42 thanks in advance Dec 19 09:37:03 rotfl: address: Dhirubai Ambani Knowledge City, Dec 19 09:39:57 <_av500_> shukla: sorry, it does not work that way Dec 19 09:40:20 <_av500_> shukla: did you good USB DAC? Dec 19 09:40:22 <_av500_> google* Dec 19 09:41:26 <_av500_> https://www.google.com/search?q=bbb+usb+dac Dec 19 09:42:00 <_av500_> https://www.google.com/search?q=output+a+sine+wave+sound+card Dec 19 09:42:15 <_av500_> https://www.google.com/search?q=output+a+sine+wave+sound+card+linux Dec 19 09:42:19 <_av500_> its all there Dec 19 09:45:27 but I am still not getting Dec 19 09:46:33 <_av500_> sorry? Dec 19 09:46:51 <_av500_> you connect a USB DAC, a usb sound card to the BBB Dec 19 09:46:59 <_av500_> that you use to output a sine wave Dec 19 09:47:07 <_av500_> a sine wave that you generate Dec 19 09:47:41 but I want to do it via python ? Dec 19 09:48:01 <_av500_> and python cannot output sound? Dec 19 09:48:16 <_av500_> https://www.google.com/search?q=generate+sound+in+python Dec 19 09:49:18 ok Dec 19 09:49:58 umm will it work http://www.ebay.in/itm/PCM2704-USB-DAC-USB-To-S-PDIF-Sound-Card-Decoder-Board-3-5mm-Analog-Output-/181598869711?pt=IN_Computer_Components&hash=item2a4822d8cf Dec 19 09:53:23 <_av500_> http://www.ebay.in/itm/HEAVY-DUTY-USB-3D-SOUND-CARD-WITH-MIC-FOR-PC-LAPTOP-QUANTUM-/111469860888?pt=IN_DVD_Players_Recorders&hash=item19f41f1818 Dec 19 09:53:27 <_av500_> a bit cheaper Dec 19 09:53:33 <_av500_> usually they work Dec 19 09:53:45 <_av500_> they are like $5 Dec 19 09:53:48 <_av500_> here Dec 19 09:54:34 hmm Dec 19 09:55:12 any other product that you can sugget me ? Dec 19 09:55:40 *suggest Dec 19 09:55:53 <_av500_> $5 for a start sounds good to me Dec 19 09:57:29 okay Dec 19 09:57:56 now i suugest need to find how to output sound via usb in python Dec 19 09:58:05 ? Dec 19 10:00:01 shukla: i'm sorry to tell you, but you sound like a 10 year old who wants to climb a mountain, but doesnt know which way to go Dec 19 10:01:45 yeh you can say so cause this assignment has been forced to me by my professor and he ask me complete it in 24 hours Dec 19 10:01:53 and I have no idea about BBB Dec 19 10:01:58 o_0 Dec 19 10:02:19 what are you studying, and which year? Dec 19 10:03:09 so i need to arrange a proper hardware and programme in python nad programme is pritty large but the output will be a sine wave I can do the programme but the interfacing stuuf IDK Dec 19 10:03:24 third year of computer engg Dec 19 10:03:28 sounds like "please do my work". basically. Dec 19 10:04:04 yeh Dec 19 15:23:44 hi guys. I just dd'd the latest ubuntu console image to my beaglebone black and wanted to know how device tree overlays are handled now Dec 19 15:30:18 mistawright, http://elinux.org/Beagleboard:Capes_3.8_to_3.14 (unless you want overlays, then downgrade: sudo apt-get update ; sudo apt-get install linux-image-3.8.13-bone68 ; sudo reboot) Dec 19 15:32:42 rcn-ee, I use a library for gpio and pwm located here, https://github.com/VegetableAvenger/BBBIOlib, it uses a dtbo how would i use it with the latest image you have provided? Dec 19 15:34:29 mistawright, downgrade.. Dec 19 15:35:40 so are device tree overlays no longer going to be used and if so what is replacing it Dec 19 15:35:49 rcn-ee, so are device tree overlays no longer going to be used and if so what is replacing it Dec 19 15:37:44 dts "overlays" just went mainline last week in "v3.19-rc0-merge"... it's still going to take time/manpower to move all "v3.8.x" dtbo to "v3.19.x" Dec 19 15:38:39 rcn-ee, got ya. so like you said better to downgrade for the time being and wait. thanks again for the help and hard work Dec 19 15:38:57 and "pwm" doesn't work the same in v3.14.x ;) Dec 19 15:51:56 hi, what is the max capacity SD card for a BeagleBoard Rev C4 ? Dec 19 15:52:38 the largest you can buy, I'd expect Dec 19 15:53:14 <_av500_> 2TB Dec 19 15:53:14 hvn2, "SDHC" only so 32GB Dec 19 15:53:43 why not SDXC? Dec 19 15:54:01 (assuming you'd not use exfat anyway) Dec 19 15:54:01 rcn-ee: Are GPIOs for these cape dts working? More specifically, is there anything I can do to help get an "x" on the cryptocape's atmega_gpio1_13_gpio1_17 ? ;) Dec 19 15:54:02 not on the classic "omap3530"... Dec 19 15:54:30 rcn-ee: ok ty...yes, i'm using the classic version Dec 19 15:55:11 hvn2, we can use sdxc unoffically on the bbb, as it supports some of the transfer modes.. Dec 19 15:55:52 i only have the bb c4... Dec 19 15:55:53 jbdatko, we should get that to work in v3.14.x Dec 19 15:57:17 rcn-ee: Great, thanks. Dec 19 15:57:54 also, i've been trying to get several ready-to-use images such as circuitco angstrom, opensuse and ubuntu12.04 and 14.04, but only the 12.04 boots correctly on my BB. Is this known to happen ? Dec 19 15:58:27 jbdatko, the syntax changed for gpio, at the time i built that dts i don't know the syntax.. need to grab the board and test.. Dec 19 15:59:13 hvn2, this one should work: http://elinux.org/BeagleBoardUbuntu#BeagleBoard_.28classic.29 but your u-boot might be too old an ancient just "nand erase.chip" to fix that.. Dec 19 16:02:24 i have a new usb wifi which requires ubuntu14.04 (tested on other machine)...when i run ubuntu 12.04 on the BB it offers to upgrade to 14.04. Can anyone tell me if this can be done safely ? I tried but the 4 GB card I use seemed too small.. Dec 19 16:03:17 ubuntu tells you that automaticly... weither or not they actually support the hardware.. Dec 19 16:04:15 they stopped offically support the beagleboard classic years ago, if you want to use ubuntu and want something actually tested and works use: http://elinux.org/BeagleBoardUbuntu#BeagleBoard_.28classic.29 Dec 19 16:04:35 Just remember, you'll probally have to erase the bootloader in nand.. Dec 19 16:04:45 i know,....but can you tell if it will work? Or don't you know...because the 14.04 console version I found doesn't boot Dec 19 16:05:21 It works, i tested it on a c4 before i uploaded it.. BUT you have to clear out the "OLD" ancient bootloader in nand first.. Dec 19 16:05:31 ahhh ok....ty Dec 19 19:22:37 Trying to install android 4.4.4 from http://www.2net.co.uk/tutorial/android-4.4-beaglebone on my beaglebone black, but nothing happens when I power it having the boot button held down. I'm using a 32GB micro sd, could that be it? Dec 19 19:54:31 Would a brand new Beaglebone black boot from an 32GB sd? I've had no luck, and thought maybe it didn't support that size. Dec 19 19:55:49 jam01, it supports it, just fine... if the bootloader was installed correctly.. Dec 19 19:58:09 Alright, thank you. I'll give it another go right meow. Maybe the downloaded img was corrupted. Dec 19 19:59:57 don't they have a md5sum so you can verify? Dec 19 20:01:45 Was just checking for that, no md5. It's a Android 4.4.4 image from http://www.2net.co.uk/tutorial/android-4.4-beaglebone copying to the sd again right now. Dec 19 21:11:13 are there any prebuilt gstreamer 1.2 packages available for ubuntu on the beaglebone black? Dec 19 21:15:10 not even showing up for x86: http://packages.ubuntu.com/search?suite=vivid§ion=all&arch=any&keywords=gstreamer1.2&searchon=names Dec 19 21:16:01 its 1.0 on x86 currently. on 14.04. Dec 19 21:29:37 hi I have question to ask. We created a transistor circuit to drive a dc motor but then suddenly the BBB is not powered on again. Dec 19 21:30:04 My question is that should we be carefull about the voltage of the pins or the current drawn from them also Dec 19 21:31:06 yeap.. you should be.. those limitations are listed in the srm. Dec 19 21:37:04 guess they didn't want to wait for an answer Dec 19 21:37:43 not careful about current/voltage limitations, not careful about keeping IRC open... **** ENDING LOGGING AT Sat Dec 20 02:59:59 2014
