**** BEGIN LOGGING AT Wed Jan 07 02:59:58 2015 Jan 07 04:12:15 my bbb/debian system does NOT have the g_multi kernel module loaded and i don't know why. Jan 07 04:12:46 does that kernel module always get loaded or is it conditionally loaded? Jan 07 04:13:36 in other words, shouldn't i be able to plug in my usb at any time (e.g., even when i'm already powered up by an external, non-usb power source) and get an NDI network interface? Jan 07 04:13:48 NDIS Jan 07 04:15:13 debian 7.6/wheezy Jan 07 04:15:35 (the console version, if that makes a difference) Jan 07 09:00:41 Someone here with a Aptina MT9P031 camera on BeagleBoard xM? Jan 07 09:25:25 Hi i need to install the Angstrom latest os in the BBB flash memory(2GB).Angstrom Distribution (BeagleBone Black - 2GB eMMC) 2013-09-04 Jan 07 09:26:00 But after extracted the image file it shows 4GB Jan 07 10:47:29 Hello all ! Jan 07 12:29:09 hi Jan 07 12:29:26 whats the maximum timer frequency clock on si335x? Jan 07 12:29:32 200Mhz? Jan 07 12:29:45 erm is it SYSCLK? Jan 07 13:06:37 Laurenceb: check the TRM Jan 07 13:13:15 Hello, I need you guys help. My black BeagleBoard not inivia HDMI video however I can access via ssh with ethernet and usb ... any suggestions ?? I've tried site procedures and unsuccessful. Any chance of this board be defective in HDMI output ??? Jan 07 13:15:02 RobsonSilva: you can see if HDMI is connected or not by xrandr Jan 07 15:13:57 Hi, I've been developing a digital synth with Arduino, but I'm rapidly running out of processing power before getting to any of the fun stuff I want to do. So I want to upgrade to a microprocessor with way more power. The beagleboard black has obviously caught my eye but I have a few questions... Jan 07 15:15:41 Does it have to be programmed from within itself? Jan 07 15:16:45 no Jan 07 15:16:54 you can program it any way you want Jan 07 15:17:06 it's easiest to have full toolchain on it on linux Jan 07 15:17:21 it simplifies whole develop->compile->test cycle Jan 07 15:17:29 you avoid a lot of copying Jan 07 15:17:56 Does it have to have Linux on it? And does having Linux running slow it down? Jan 07 15:20:59 IronAttorney: technically it doesn't have to run linux, in practise you basically have to because rewriting all the system stuff is moot and pretty complex Jan 07 15:22:02 e: I've not been programming long, done some C (for Arduino) Jan 07 15:22:26 then you probably have some learning to do Jan 07 15:22:48 especially if you are trying to do realtime stuff Jan 07 15:23:06 a little C++, a bit of ruby, and small amounts of other formats, will it be easy to learn? Jan 07 15:23:26 for "slowing it down" - well, of course every part of software that is acutally executed eats up some processor cycles. the question would be more meaningful in the way "can i archieve X with it" Jan 07 15:23:50 a good point Jan 07 15:23:54 and the better X is defined, the more meaningful the answers will be Jan 07 15:24:32 I pressure it doesn't cut too drastically into the 1Ghz though? Jan 07 15:24:51 "depends" Jan 07 15:25:15 and notice: whenever a question is particularly bad, the answer will probably be "depends" Jan 07 15:25:15 the cpu itself is probably not a reason for concern Jan 07 15:25:55 it has a bunch of other bottlenecks though Jan 07 15:26:33 Alright. so last 2 questions, is there anything about the board that could limit a high power audio synth/DSP project? Jan 07 15:26:45 define high power Jan 07 15:27:08 define synth Jan 07 15:27:12 define DSP Jan 07 15:27:20 and first you have to solve audio output Jan 07 15:27:45 but for doing an fft or two, it's surely powerful enough Jan 07 15:27:59 maybe not if you want to do floating point fft though Jan 07 15:30:10 IronAttorney: how will you do audio output? Jan 07 15:33:10 sAssuming no floating point, I'd want it to have at least 3 oscillators, each of which is entirely different and each has to crunch some numbers before each sample is mixed and output, it would need to have a whole heap of encoders to keep track of which alter various parameters in real time, I would want oscillators to FM each other, I would like both a direct audio output and the ability to send the audio data digitally to an Jan 07 15:33:39 accept modulations from other boards Jan 07 15:34:03 as well as process midi note data of course Jan 07 15:35:10 i think it has hw floating point, but i'd stick with integers and q number formats if performance was an issue Jan 07 15:36:02 IronAttorney: apart from the hardware topics: evaluate how many cycles you need for one iteration, define how many iterations you need per second, then do a rough estimate if this does not exceed maybe 500Mhz. Jan 07 15:36:36 might want to do parts of those things in asm too Jan 07 15:36:39 then you should get an idea if you are in the range Jan 07 15:36:42 sounds like a really fun project :) Jan 07 15:37:11 more fun than doing i2c in go on that thing anyway... Jan 07 15:39:21 IronAttorney: but all this is in no way BBB specific. you can always go ahead and develop on some linux box, and when you have the software done evaluate if there is some hardware available to run it on. Jan 07 15:40:00 OHas been so far :D but I'm a long way off the skill level to pull it off. So my last question, do you think with a basic knowledge of arduino and a few programming formats, would I be able to slowly but surely get a grip on the beagleboatd? r . Jan 07 15:40:39 IronAttorney: if you can get a grip on programming for linux on your desktop, then yes. Jan 07 15:41:18 IronAttorney: the BBB is way more comparable in terms of programming to whatever pc-style hardware you know, than to an arduino or any other uC stuff Jan 07 15:41:37 read that as "the BBB is not an arduino on steroids" Jan 07 15:42:15 cool, so you think I should try that first? Not a bad idea! Jan 07 15:42:55 definitely learn to program on an os (in this case probably linux) first. no need to spend money on HW Jan 07 15:43:03 test Jan 07 15:43:28 niro: failed! horribly, terribly FAILED!!! Jan 07 15:43:33 Lol Jan 07 15:43:35 Cool, well thank you very much for your patients and assistance! I think I've got all the info I need Jan 07 15:45:10 Hello, is there an option to add a second ethernet port Jan 07 15:45:51 oh one more q actually, as you program it from Linux, I pressure there's a variety of programming platforms you can use, any that work particularly well or you would recommend? Jan 07 15:46:14 IronAttorney: define "programming platform" Jan 07 15:46:24 blackline: not "easily" Jan 07 15:47:43 Err, maybe that's the wrong word. I watched a video where someone programmed it with python, is that standard or can you use anything? Jan 07 15:47:47 blackline: you can check out phytecs wega board for example, which cames with two ports. and i'm sure there are others too that i just don't know Jan 07 15:48:51 IronAttorney: "any part of software that gets executed eats up cycles"... feel free to interpret that for a high-level interpreted language and compare to a rather low-level, compiled language Jan 07 15:49:43 IronAttorney: if you're going to do dsp and similar, stick with c or c++ Jan 07 15:50:19 OK cool, thank you all for your help! Jan 07 15:50:33 catch you later Jan 07 16:09:09 Hey guys, I was wondering which emmc the SD card uses and if the pins are available on the expansion headers. I am trying to design a flashing cape that would manipulate the boot pins with some pull-up resistors and provide the flasher boot image without having to put an SD card in the slot on the BBB. Jan 07 16:19:23 hi all Jan 07 16:20:41 * hitlin37 is happy that he can touch these newer baytrail chips without burning his finger Jan 07 16:21:37 that happiness was short lived for 5 sec. Jan 07 17:47:31 jkridner|work: ping Jan 07 18:14:19 hi all! Jan 07 18:15:51 i'm trying to develop an Artnet to DMX system using a BBB [formerly an ETHERNET to RS-485 system], but i'm having timing issues using an already well-known- working software. So the only thing i can think about it's about BBB UART speeds or something similar. I found other guys having problem setting UARTs to 250000. How can i? Jan 07 18:16:56 setty? Jan 07 18:17:56 the software should set them good but i have that problems. Is there any known speed problem with BBB UARTs over 115k? and is there any known solution? Jan 07 18:20:18 I think with the higher speeds you may need flow control Jan 07 18:21:10 DMX has no flow control Jan 07 19:13:15 If anyone else is interested in using the TI Pin Mux Tool, check out the repository I just created. https://github.com/abferm/BeagleBone-Black-TIPinMux/ Jan 07 19:21:51 abferm: cool, thanks Jan 07 19:25:28 is there any known problem setting/using BBB UARTs @ 250k? Jan 07 21:09:24 I seek help with using the init-eMMC-flasher-v3.sh Jan 07 21:09:52 I booted fine from rcn-ee deaib image and fail to install it to the eMMC Jan 07 21:10:16 last lines are: Jan 07 21:10:19 --flushbufs flush buffers Jan 07 21:10:19 --rereadpt reread partition table Jan 07 21:30:36 Anyone alive? Jan 07 21:31:09 nope Jan 07 21:31:22 noway Jan 07 21:32:26 not on your life Jan 07 21:41:28 anyone know where i can get bone-debian-7.6-console-armhf-2014-09-04-2gb.img Jan 07 21:41:43 i downloaded it a few weeks ago and can't find it again now. Jan 07 21:45:21 the closest i can find is https://rcn-ee.net/deb/microsd/wheezy/bone-debian-7.6-console-armhf-2014-08-13-2gb.img.xz Jan 07 21:50:22 or more generally here: https://rcn-ee.net/deb/microsd/wheezy/ Jan 07 22:00:12 can anyone a sdcard reader that works under linux? i'm using a Kodak R130 but it seems to be VERY slow (40 minutes to program 1.8 GB) Jan 07 22:00:20 anyone recommend Jan 07 22:04:23 nm about bone-debian-7.6-console-armhf-2014-09-04-2gb.img. i'm going with 7.7 Jan 07 22:12:03 ? Jan 07 22:12:17 ddrown: any suggestions on sdcard? Jan 07 22:12:58 yates: the only thing I ran into was my sdcard only worked when it was powered by the DC jack and not the USB device port Jan 07 22:13:10 ewe. Jan 07 22:13:24 I actually wrote the image with the BBB itself Jan 07 22:13:29 there's no such option with this Kodak. Jan 07 22:13:30 I wouldn't recommend that Jan 07 22:13:59 oh, you're talking about an adapter on a different machine Jan 07 22:14:11 yes Jan 07 22:14:42 sdcard -> sdcard reader -> linux desktop pc Jan 07 22:14:56 how slow is slow? 1MB/s? less? Jan 07 22:15:09 1.8 MB/s Jan 07 22:15:59 no, that's what it reported! it was actually about 0.6 MB/s Jan 07 22:16:49 # dd if=/dev/zero of=file bs=4k count=10000 conv=fdatasync Jan 07 22:16:49 40960000 bytes (41 MB) copied, 10.3938 s, 3.9 MB/s Jan 07 22:16:53 on the BBB itself Jan 07 22:17:18 impressive Jan 07 22:17:30 heh, that's pretty slow Jan 07 22:17:43 compared to a SSD or disk Jan 07 22:18:00 apples/oranges Jan 07 22:18:11 true Jan 07 22:18:22 but oranges are slow Jan 07 22:18:24 i think my ssd does upwards of 500 MB/s? Jan 07 22:19:35 ha. Jan 07 22:49:46 ok, https://rcn-ee.net/deb/microsd/wheezy/bone-debian-7.7-console-armhf-2014-10-29-2gb.img.xz doesn't boot. Jan 07 22:52:40 help! Jan 07 22:52:53 what's going on with these freakin' images/ Jan 07 22:52:54 ? Jan 07 22:53:20 you're not writing the .xz are you? Jan 07 22:54:18 no. Jan 07 22:54:30 i used linux's unxz to decompress it Jan 07 22:55:54 then i use dd if=x.img of=/dev/sdd Jan 07 22:56:21 Hey guys, I'm trying to mux out 2 uarts with rts+cts, and it looks like the only way to do that is to use PR1_UART0. Is it just like any other UART port, or does the PRU complicate things? Jan 07 22:57:23 anyone else here successfully use bone-debian-7.7-console-armhf-2014-10-29-2gb? Jan 07 22:58:18 ddrown: would you mind trying it? Jan 07 22:58:58 just see if it boots, e.g., if it opens a network connection on 192.168.7.2 via NDIS/usb Jan 07 22:59:38 i've tried two different sdcards, rebooting severl times. no joy. Jan 07 23:00:02 https://rcn-ee.net/deb/microsd/wheezy/bone-debian-7.7-console-armhf-2014-10-29-2gb.img.xz Jan 07 23:01:51 yates: I think I used one of the 2014-10-29 images when I flashed. I can't flash now as my BBB is doing things for me Jan 07 23:03:35 # cat /etc/dogtag Jan 07 23:03:35 BeagleBoard.org BeagleBone Debian Image 2014-05-14 Jan 07 23:03:39 oh, I guess I used an older one Jan 07 23:57:15 hey I'm trying to use my BBB as a host for live performance midi sequencing software I've written. But hit quite a roadblock with what I believe is an issue with the alsa sequencer Jan 07 23:58:05 usb midi devices show up in the output to 'amidi -l', but not in the output of 'aconnect -io' Jan 07 23:58:27 just curious whether anyone here experienced the same issue and found a way through it? Jan 08 00:18:21 ok just managed to fix this by installing a new kernel image... Jan 08 01:09:55 hi all **** ENDING LOGGING AT Thu Jan 08 02:59:59 2015
