Jul 15 05:36:14 <Bilal_> hello i am facing problem with my network. I have beaglebone black rev c. The ethernet on it just gives 5kb max. varies on my laptop the speed is more than 250kb. I tested BBB on my home network and it was working fien giving abt 100kb but i have to work on project in the office and i am really fed up of this 5kb problem. I want to diagnose the ETHERNET. i tried using ethtool but it doesn;t help much
Jul 15 05:37:16 <Bilal_> I want to check if the eth0 is set to 10mbps or 100 mbps etc etc stuff but how to do that in debian i do not know
Jul 15 05:44:48 <Bilal_> eth0 output
Jul 15 05:44:55 <Bilal_> i mean ethtool output
Jul 15 05:44:58 <Bilal_>  ethtool -s eth0 autoneg off speed 100 duplex full Cannot get current device settings: Operation not supported   not setting speed   not setting duplex   not setting autoneg
Jul 15 05:45:19 <Bilal_> hope some one will answer the question
Jul 15 06:00:16 <Bilal_> any body
Jul 15 06:20:37 <vagrantc> Bilal_: cat /sys/class/net/eth0/speed
Jul 15 06:20:46 <vagrantc> should show you what speed it's negotiated at
Jul 15 06:21:06 <vagrantc> muuunis: no spam please.
Jul 15 06:26:28 <Bilal_> vagrantc: cat: /sys/class/net/eth0/speed: Invalid argument
Jul 15 06:26:38 <Bilal_> vagrantc: cat /sys/class/net/eth0/speed: Invalid argument
Jul 15 06:26:59 <Bilal_> i can't view the speed file
Jul 15 06:29:39 <Bilal_> failed to say that i am using DEBIAN WHEEZY (already flashed new version)
Jul 15 06:29:53 <Bilal_> june version (or may)
Jul 15 06:30:02 <Bilal_> Linux beaglebone 3.8.13-bone50 #1 SMP Tue May 13 13:24:52 UTC 2014 armv7l GNU/Linux
Jul 15 06:30:33 <Bilal_> i m using the bbb currently so if you need ANY output i can provide
Jul 15 06:34:31 <vagrantc> Bilal_: ls /sys/class/net/eth0 reveal anyting useful?
Jul 15 06:35:01 <vagrantc> the exact location of the sys files may be different with 3.8.x ... i'm currently looking at a 3.14 install
Jul 15 06:38:52 <vagrantc> Bilal_: gotta head out, good luck! hopefully someone else can help you if you don't figure it out for yourself
Jul 15 07:38:02 <demeteor> Hello,  I think I might have damaged or burned my usb host on bbb. if I use the command lsusb i can see both of the usb appearing on the terminal but it does not power anything up.
Jul 15 07:39:43 <demeteor> what I did was to connect it to a power source to check the motors and led lights. then removed power. connected the usb camera and tried to turn it on. then this happened. no idea whats going on,. any way to check if its just disabled it self ? or if its trully burned?
Jul 15 07:44:58 <tbr> demeteor: how do you power the motors?
Jul 15 07:46:10 <demeteor> from ESC that gets power from a battery
Jul 15 07:46:32 <demeteor> I just connected my Android phone and it charges up.
Jul 15 07:47:39 <demeteor> so  something else might be wrong  ?
Jul 15 07:51:47 <tbr> I don't know your setup, but if something went seriously wrong you might have actually damaged the USB phy
Jul 15 07:52:03 <tbr> did you try booting a different image?
Jul 15 07:52:17 <demeteor> yes I did
Jul 15 07:52:20 <demeteor> nothing again
Jul 15 07:52:31 <demeteor> but it gives power output
Jul 15 07:52:31 <sudoertor> demetor, what power do the lights and motor need total?
Jul 15 07:52:43 <demeteor> my phone charges from the BBB usb host right no w
Jul 15 07:53:50 <demeteor> 12v but its external not directly connected to BBB for power. they are conencted to the BBB only to get signal from it
Jul 15 07:54:37 <tbr> I don't know what happened, but it sounds like you damaged the signal pins of your USB port
Jul 15 07:54:52 <tbr> charging is directly from the 5V rail, so that's independent
Jul 15 07:56:07 <demeteor> how can we check it up? right now it has nothign connected to it
Jul 15 07:56:22 <demeteor> its just a BBB with debian
Jul 15 08:00:03 <tbr> if you have the equipment you could look with a scope at the USB bus to see if anything happens, I guess
Jul 15 08:00:16 <tbr> but it very much sound like it's dead
Jul 15 08:00:29 <tbr> I wonder why
Jul 15 08:00:50 <demeteor> yeah coz how could it. it was irrelevant to what happened there
Jul 15 08:01:10 <demeteor> I mean how could the usb hub die and the BBB be just fine ?
Jul 15 08:03:02 <tbr> by something happening between whatever you connected and the BBB
Jul 15 08:03:20 <demeteor> I connected a camera
Jul 15 08:03:21 <tbr> e.g. if there was some sort of voltage spike or something else on the bus
Jul 15 08:03:50 <demeteor> when I was about to finish with this thing now I have to wait for a new one -_- lol
Jul 15 08:05:12 <sudoertor> what software can be used to open the beaglebone's schemeatics?
Jul 15 08:09:44 <Bilal_> Hello again
Jul 15 08:10:02 <sudoertor> hi
Jul 15 08:11:58 <Bilal_> I want to ask question about eth0 speed (internet) i am getting only 5kb (only on a specific network) and i want to find out what exactly is wrong with the BBB rev c OR the network. So kindly guide on how to identify the problem. I tried ethtool but it doesn't output setting, status of my BBB rev c. I do not know why. Plus mii-tool error out when run, I want to know why is the internet speed so very slow in this network
Jul 15 08:12:42 <Bilal_> mii-tool output
Jul 15 08:12:43 <Bilal_> SIOCGMIIPHY on 'eth0' failed: Unknown error 524 no MII interfaces found
Jul 15 08:12:59 <Bilal_>  ethtool eth0
Jul 15 08:13:07 <Bilal_> Settings for eth0:         Current message level: 0x00000000 (0)          Link detected: yes
Jul 15 08:13:12 <tbr> Bilal_: try connecting a different ethernet device to the network
Jul 15 08:14:01 <Bilal_> i didn't get it.. I tried using WIFI dongle it works well... (it is pain in the a** to configure WIFI dongle on THIS SPECIFIC network)
Jul 15 08:14:32 <Bilal_> my pc work gr8 on the network (laptop i mean)
Jul 15 08:15:24 <tbr> have you tried talking to the network administrator?
Jul 15 08:15:58 <tbr> have you tried connecting it through a switch to the network?
Jul 15 08:16:07 <woglinde> I would use tcpdump or so to see whats going on
Jul 15 08:17:57 <tbr> that's also a very good point
Jul 15 08:29:16 <Bilal_> wait i will try tcpdump
Jul 15 08:29:48 <Bilal_> listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes
Jul 15 08:32:50 <Bilal_> i can't paste it here
Jul 15 08:34:04 <Bilal_> http://pastebin.com/mkDm6R1t
Jul 15 08:37:54 <cuba> Bilal_: have you checked thge cable?
Jul 15 08:39:53 <Bilal_> http://pastebin.com/5ttfnqZk
Jul 15 08:40:17 <Bilal_> sorry for the pastbin previous link this link contain downloading test dump http://pastebin.com/5ttfnqZk
Jul 15 08:40:33 <Bilal_> what is thge cable ?
Jul 15 08:40:52 <cuba> check the cable, change it it looks like an issue with the connection
Jul 15 08:41:01 <Bilal_> I want to also update all that i was able to use the lan connection on my home network without problem
Jul 15 08:41:18 <Bilal_> but i am having problem in this perticular network (office only)
Jul 15 08:41:33 <Bilal_> at home it was giving me speed of 200kbps (normal)
Jul 15 08:42:00 <Bilal_> well i will try to directly connect the device to the ROUTER of office hold on...
Jul 15 08:42:44 <Bilal_> Also cuba i tested the cable at my home network there is  no problem.. i have 3-4 cable right now on the desk...
Jul 15 08:42:54 <Bilal_> but it is not the problem of cable..
Jul 15 08:42:58 <cuba> i had the same issue
Jul 15 08:43:05 <cuba> and it was the physical connection
Jul 15 08:43:19 <Bilal_> tbr: i will check applying directly to the router
Jul 15 08:43:27 <cuba> good luck
Jul 15 08:49:16 <Bilal_> hmm sorry had to remove the cable (which i was working on) to test the bbb
Jul 15 08:49:26 <Bilal_> will get the ip now w8
Jul 15 08:50:54 <Bilal_> okay i got the ip
Jul 15 08:50:57 <Bilal_> loging in
Jul 15 08:51:22 <Bilal_> lol
Jul 15 08:51:25 <Bilal_> Problem solved
Jul 15 08:51:34 <Bilal_> I am getting 200kbps
Jul 15 08:51:57 <Bilal_>  wget http://speedtest.reliableservers.com/10MBtest.bin

Jul 15 08:52:12 <Bilal_> sorry guys
Jul 15 08:52:23 <Bilal_> and thank you it resolved the issue
Jul 15 08:52:41 <Bilal_> cuba are you there ?
Jul 15 08:56:42 <woglinde> bad cable?
Jul 15 08:56:49 <woglinde> just for the record
Jul 15 09:03:07 <freezevee> Hi all... I have flashed the BBB-eMMC-flasher-debian-7.5-2014-05-14-2gb into my BBB and I have an issue with Sleep mode (or hibernate). I can't manage to keep the BBB from shutting down automatically after a short period of inactivity. any ideas ?
Jul 15 09:14:35 <sirkha> Hi, I am designing a cape that will only need to use a UART line, sometimes, is there a way to do that, from a beaglebone black software perspective?
Jul 15 09:15:17 <sirkha> Hardware wise, it will only be hooked up to the pins when needed
Jul 15 09:16:13 <sirkha> (using an analog switch... MAX4519)
Jul 15 09:23:53 <av500> sirkha: sure, why not
Jul 15 09:35:49 <spike_> can emmc be partitioned before the uboot loads at MLO stage ...... ?
Jul 15 09:37:55 <av500> ?
Jul 15 09:39:24 <spike_> can emmc be partitioned before the uboot loads during a booting process....?
Jul 15 09:42:16 <av500> sure
Jul 15 09:42:25 <av500> you can write an MLO that does that
Jul 15 10:29:39 <vmayoral|pc> anyone got experience with PWR button hacking? It seems that i'm experiencing http://bugs.elinux.org/issues/85
Jul 15 10:29:47 <vmayoral|pc> any suggestion on how to disable automatic shutdown?
Jul 15 11:04:01 <varad> Is the BBB RAM connected to CPU through OCMC or GPMC? I'm confused between whether to use the GPMC address (0x0) or the Public RAM Address mentioned in the AM335x TRM.
Jul 15 11:06:27 <varad> (I'm working in the initialization phase of the CPU)
Jul 15 11:08:40 <tbr> you could take a look at the design files
Jul 15 11:08:48 <tbr> that would answer such questions
Jul 15 11:09:57 <jacekowski> varad: GPMC
Jul 15 11:10:06 <jacekowski> varad: OCMC is for builtin SRAM
Jul 15 11:23:41 <eballetbo> Is the BlueSteel Basic board available to buy somewhere ?
Jul 15 11:51:47 <jkridner> I managed to buy one...
Jul 15 11:52:53 <jkridner> I was VERY disappointed to see it ship in a BeagleBone Black box.
Jul 15 11:53:37 <jkridner> That should be completely ignored.
Jul 15 11:54:22 <jkridner> I also found I couldn't power it off of USB for some reason, but I didn't investigate. Seems to be something with the current drawn at boot.
Jul 15 11:54:51 <jkridner> Otherwise, it is pretty nice, running BeagleBone Black code and not having eMMC/HDMI pins loaded.
Jul 15 11:55:53 <jkridner> I bought it from http://www.boardzoo.com/index.php/bluesteel/bluesteel-basic.html
Jul 15 11:56:01 <jkridner> which seems to be a broken link now.
Jul 15 13:09:44 <jkridner> eballetbo: http://specialcomp.com/beaglebone/ has the new purchase link
Jul 15 13:11:39 <eballetbo> jkridner: thanks
Jul 15 13:12:03 <eballetbo> but looks like is only a pre-order, out of stock :(
Jul 15 13:14:08 <jkridner> boardzoo said preorder when I ordered, but it got here within a few days
Jul 15 13:30:46 <luastoned> hey, so I tried to create loop in c++ that executes ~5k times per second (works quite nice with nanosleep) .. now when I try to increase that to 10k it works, but anything beyond that just does not happen.. it seems like once I use nanosleep I can't get more than 10k , are there any alternate timers on the bbb that I could use for this?
Jul 15 13:48:54 <tbr> luastoned: why would you need that?
Jul 15 13:49:39 <luastoned> i need to read from a buffer and output at that rate (via spi)
Jul 15 13:50:59 <Letothe2nd> didn't i suggest weeks ago to just have an IIO driver do that?
Jul 15 13:51:13 <Letothe2nd> and then read bulked into userspace instead of small burps.
Jul 15 13:51:33 <luastoned> not sure, I just got into setting up the bbb and experimenting with it
Jul 15 13:51:39 <tbr> *burp*
Jul 15 13:51:46 <Letothe2nd> then read up and experiment with IIO :)
Jul 15 13:56:12 <luastoned> mhm, the main goal is to drive my rgb laser via a custom dac, the dac should get data from 10k to 30k times / sec via spi..
Jul 15 13:56:49 <Letothe2nd> luastoned: ok, so what was this supposed to tell me?
Jul 15 13:57:20 <luastoned> no idea, im just not very familiar with low level io
Jul 15 13:58:07 <Letothe2nd> luastoned: you are trying to bang bytes one after the other directly... theres not much more low level
Jul 15 13:59:18 <luastoned> well, I got that part figured out (I can access the dac), I just need to create a steady tigger
Jul 15 14:00:14 <Letothe2nd> still i think you are wasting time and going wrong.
Jul 15 14:00:29 <Letothe2nd> the iio subsystem was designed to do exactly what you are trying to archieve
Jul 15 14:00:30 <Letothe2nd> http://git.kernel.org/cgit/linux/kernel/git/gregkh/staging.git/tree/drivers/staging/iio/Documentation?id=refs/heads/staging-next
Jul 15 14:01:01 <Letothe2nd> or more precisely, read at least the top 20 lines of http://git.kernel.org/cgit/linux/kernel/git/gregkh/staging.git/tree/drivers/staging/iio/Documentation/overview.txt?id=refs/heads/staging-next
Jul 15 14:02:55 <luastoned> It sounds like exactly what I need, I'll try to find some sample code .
Jul 15 14:03:19 <Letothe2nd> QED
Jul 15 14:03:44 <Letothe2nd> there are even readymade drivers in the kernel for inspiration.
Jul 15 14:07:22 <luastoned> could you link me to one of those?
Jul 15 14:08:46 <Letothe2nd> hmmm are you actually willing to put in own effort?
Jul 15 14:08:49 <Letothe2nd> *sigh*
Jul 15 14:08:57 <Letothe2nd> but hey, i'm having a good five minutes
Jul 15 14:08:58 <Letothe2nd> http://lxr.free-electrons.com/source/drivers/iio/dac/
Jul 15 14:09:42 <Letothe2nd> even spi-types already there, just a small step to whack them into whatever form needed.
Jul 15 14:13:28 <luastoned> okay, thanks for the help. I'll try to fight my way through those files!
Jul 15 14:14:05 <Letothe2nd> just prick whatever resembles your hardware most and then beat it into shape
Jul 15 14:16:48 <josh_> why does my beaglebone come up as an uknknown device on my windows 7 compuyter?
Jul 15 14:17:05 <jkridner> the ROM bootloader is one device...
Jul 15 14:17:21 <jkridner> then you need to install the drivers for the other devices after it boots.
Jul 15 14:17:31 <jkridner> did you run the driver installer?
Jul 15 14:17:34 <luastoned> Letothe2nd I have two 12bit chips and one 16bit
Jul 15 14:17:41 <josh_> i did
Jul 15 14:17:54 <josh_> it however wasnt recognized as a usb device
Jul 15 14:17:57 <jkridner> http://github.com/jadonk/beaglebone-getting-started has newly signed drivers.
Jul 15 14:17:59 <josh_> and the drivers couldnt install
Jul 15 14:18:08 <jkridner> josh_: hmmm... did the board finish booting?
Jul 15 14:18:33 <jkridner> if it doesn't finish booting, the bootloader will show up as a device and I haven't shipped any drivers for that.
Jul 15 14:18:43 <jkridner> do you have the heartbeat LED?
Jul 15 14:18:50 <Letothe2nd> luastoned: thats pretty much a no-information.
Jul 15 14:19:10 <Letothe2nd> luastoned: rather look at their datasheets, if one of their related parts is already supported
Jul 15 14:19:18 <josh_> im fairly sure..all the blue lights came on, it said the drivers couldnt install thoug, then i tried the drivers from the site, and yes i did have the heartbeat, and under other/unknown devices it sys BEagleBoneBlack
Jul 15 14:20:01 <luastoned> Letothe2nd tbh all of this is pretty new to me, I never did anything that close to hardware and I'm just getting started..
Jul 15 14:22:42 <jkridner> josh_: you should end up with a networking device, a USB flash device and a serial device, as well as a composite device encompassing those. there is possibility of an unknown device (the bootloader), but it should go away shortly after booting.
Jul 15 14:23:11 <jkridner> I could provide a driver for the bootloader to give it an identifier, but until the USB boot utility is finished, it wouldn't really do anything.
Jul 15 14:23:18 <josh_> ok i will uninstall whatever it has right now and replug it in ill update in a minute
Jul 15 14:26:36 <Letothe2nd> luastoned: well reading a datasheet you obviously can , otherwise you would not have been able to pipe out the bytes manually
Jul 15 14:28:21 <luastoned> Letothe2nd yeah sure, what I don't understand though is how this iio driver is supposed to help me create the 10k/sec loop
Jul 15 14:30:32 <Letothe2nd> luastoned: you just create 10k values once a second and then have iio pipe them out
Jul 15 14:30:46 <luastoned> at a steady interval?
Jul 15 14:31:11 <luastoned> that's the only real restriction I have..
Jul 15 14:31:36 <Letothe2nd> thats what its meant for
Jul 15 14:31:48 <Letothe2nd> really, you need to show a little more own effort in reading
Jul 15 14:31:52 <luastoned> Gotcha
Jul 15 15:05:05 <josh_> jkridner: it said that it couldnt install the device drivers, now it is under other devices in my device manager as BeagleBoneBlack
Jul 15 15:12:41 <jkridner> you should try the signed drivers at https://github.com/jadonk/beaglebone-getting-started/releases/tag/1.0.1 and let me know how it goes
Jul 15 15:14:15 <josh_> ill try it
Jul 15 16:12:15 <Josh> jkridner: installed the drivers...didnt work
Jul 15 16:12:31 <Guest39287> its josh
Jul 15 16:12:38 <jkridner> can you connect to the board using your browser?
Jul 15 16:13:11 <Guest39287> 192.168.7.2?
Jul 15 16:13:15 <jkridner> can you give some more details on what exactly you are trying and what exactly didn't work.
Jul 15 16:13:26 <jkridner> typically, yes, that'd be the address.
Jul 15 16:13:42 <Guest39287> i plugged it in, installed your drivers, it said the drivers were good and it still doesnt show up as a usb device and only an other device
Jul 15 16:14:18 <jkridner> it shows up as a drive on your computer, right?
Jul 15 16:15:03 <Guest39287> no it doenst
Jul 15 16:15:03 <jkridner> can you click the START.htm
Jul 15 16:15:39 <Guest39287> in the bone or on my windows?
Jul 15 16:16:25 <m_billybob> windows update . . .
Jul 15 16:16:31 <m_billybob> do it NOW
Jul 15 16:25:00 <Guest39287> im up to date :(
Jul 15 16:25:07 <Guest39287> ill just go to ubuntu...
Jul 15 18:09:30 <jkridner> m_billybob: appreciate if you can avoid trolling newbs.
Jul 15 18:09:51 <jkridner> m_billybob: I understand the temptation.
Jul 15 18:13:27 <m_billybob> eh ?
Jul 15 18:13:45 <m_billybob> THat wasnt a troll that was a fact
Jul 15 18:14:44 <m_billybob> either that or walk him through step by step on how to install the Windows NDIS driver. . .
Jul 15 18:15:07 <m_billybob> MSUpdates will do it automatically.
Jul 15 19:01:38 <jbdatko> Can the BBB act as an I2C slave, or is it master only?
Jul 15 19:04:47 * jbdatko thinks master only, because I'm not sure of I2C slave support in the SoC kernel driver, which would provide the slave capability. But I'm not sure.
Jul 15 19:43:41 <pjz> yah, the place to look is the kernel i2c support, which shouldn't be all that SoC-specific, I wouldn't think.
Jul 15 19:46:13 <jkridner> m_billybob: sorry for the accusation.
Jul 15 19:49:57 * ds2 stares at the Beagle Bridge
Jul 15 19:50:02 <ds2> home to many trolls
Jul 15 19:53:18 * spikebike digs for info on the beagle board and any of the SHA enabled ibuttons DS1961S, DS1963S, and DS2432
Jul 15 20:11:21 <_av500_> one could bitbang an I2C slave with the PRUs
Jul 15 20:21:18 <m_billybob2> jkridner, not  problem. Seems to be a trend on the groups that lots of people are having this issue and the last two who solved it, thats what they've done.
Jul 15 20:22:19 <m_billybob2> jkridner, I think one solved it manually by installing the drivers himself after reading a kb article but meh was too early in the morning for me to go through all that
Jul 15 20:26:42 <m_billybob> jkridner, is there a FAQ page linked off beaglboard.org ? That might be a candadite for such a page
Jul 15 20:39:08 <jkridner> The wiki has the FAQ... http://elinux.org/BeagleBone
Jul 15 20:57:15 <m_billybob> jkridner, not very visable from that link, atleast I was unable to find much in the way of a FAQ page for the BBB.FOrtunately for me, I need no such resource, but im fairly advanced.
Jul 15 20:58:47 <xenoxaos> m_billybob: is this dave?
Jul 15 20:59:10 <m_billybob> no
Jul 15 20:59:23 <__butch__1> Dave's not here, man.  :-)
Jul 15 20:59:30 <m_billybob> heh
Jul 15 21:00:06 <m_billybob> good ole cheech and chong
Jul 15 21:00:18 <__butch__1> I was hoping somebody would get the reference.  :-)
Jul 15 21:00:31 <xenoxaos> hehe
Jul 15 21:00:43 <xenoxaos> i havent seen any cheech and chong in forever
Jul 15 21:01:13 <m_billybob> same, but who that grew up in the 70's-80's could forget that album lol
Jul 15 21:07:05 <plaw> stop, dave. please stop. my mind is going. i'm afraid, dave.
Jul 15 21:08:17 <ds2> just write a proper slave driver
Jul 15 21:08:29 <ds2> it is not that hard... I done it before for the SPI stuff
Jul 15 21:29:20 <m_billybob> ds2, is ldd still the authoritive resource on that subject ( devie drivers  in linux ) ?
Jul 15 21:29:46 <m_billybob> I've never written one to date myself
Jul 15 21:29:59 <m_billybob> have a hadcopy of LDD though
Jul 15 21:40:28 <ds2> the only authoritative resource is the kernel itself.
Jul 15 21:40:44 <ds2> anything else is hearsay
Jul 16 00:24:05 <Geo> Hi- not a troll, promise. I'm looking at buying a small embedded board to handle high volumes of net flow data... <loaded vague question> is beagleboard able to handle processing high volumes of net data, or is 512 memory going to come up short? Is there another alternative that may work better?
Jul 16 00:38:05 <spikebike> define high volumes
Jul 16 00:39:22 <Geo> not saturated, but on a highly populated gbit network
Jul 16 00:39:40 <Geo> I'm not even sure if beagle has that capability
Jul 16 00:39:49 <Geo> (gbit ethernet)
Jul 16 00:40:20 <Geo> so lets say a near-saturated 100mbit spanport
Jul 16 00:46:19 <m_billybob> Geo, there is a new circuitco produced GbE bbb
Jul 16 00:46:34 <m_billybob> how long before it comes out idk but what is it you;re trying to achomplish /.
Jul 16 00:47:01 <m_billybob> err lol what are you trying to achomplish?
Jul 16 00:47:37 <Geo> grabbing data off a router span port for later analysis
Jul 16 00:48:01 <m_billybob> NOdejs is a consideration ? that is nodejs and socket.io
Jul 16 00:48:03 <Geo> dont need all the data, so hoping this little guy can do some crunching and pass along the reduced dataset instead
Jul 16 00:48:44 <m_billybob> how much throughput do you need ?
Jul 16 00:49:07 <m_billybob> from bbb to whatever
Jul 16 00:49:57 <m_billybob> bbb == beaglebone black btw
Jul 16 00:50:09 <Geo> I don't know, haven't gotten that far.. i'm more focused on how much processing is needed to sort the net traffic, that to me seems to be the larger problem
Jul 16 00:50:14 <Geo> thanks I was going to ask that :)
Jul 16 00:51:40 <m_billybob> well let me put it this way the BBB's fast ethernet is pretty fast, it peaks at around 10.8MB/s which as you probably know is dahmed fast for reads, writes is at about 10.sMB/s
Jul 16 00:52:04 <m_billybob> brb but feel fre to ask what you wantto know ill brb
Jul 16 00:53:40 <Geo> basically, lets say I have network data coming in at 8-9MB/s ... can the cpu/memory of the bbb keep up with the constant data stream coming in from the network, converting to netflow data?
Jul 16 00:54:04 <Geo> 512MB seems to be on the small side for that, but I dont know that for sure
Jul 16 00:54:56 <spikebike> why would streaming data to storage require ram?
Jul 16 00:55:09 <spikebike> especially since the netflow will be much less than the data rate
Jul 16 00:55:20 <Geo> it has to store the data somewhere while it crunches it...
Jul 16 00:55:46 <Geo> and if it can only crunch at 7mb/s or whatever, etc
Jul 16 00:55:47 <spikebike> yeah, say a few dozen packets at a time
Jul 16 00:56:05 <spikebike> btw, it's not the 10MB/sec that's the worst case, it's a zillion tiny packets
Jul 16 00:58:35 <m_billybob> Geo, depends on how you send that data but yes it should
Jul 16 00:59:08 <m_billybob> well depends on what you do with that data, before sending too of course. BUt the bbb has the rPI trumped by a good bit
Jul 16 01:00:18 <spikebike> there are faster boards with more ram, but I suspect the BBB is fine
Jul 16 01:00:38 <spikebike> taking the first dozen or so bytes of a packet, doing a pattern match, and buffering the result to storage isn't particularly hard
Jul 16 01:01:01 <spikebike> no need for intensive deep packet inspection
Jul 16 01:01:34 <m_billybob> Geo,  a good test is setup a single core VM via virtualbox and see if that handles the situation well enough. ive yet to see the beagle bog down but im not processing massive data either realy
Jul 16 01:02:22 <m_billybob> single core vm with 512 MB ram that is
Jul 16 01:02:30 <Geo> right, thats a thought
Jul 16 01:02:35 <m_billybob> and test GbE and fast ethernet
Jul 16 01:04:57 <m_billybob> but if 10/100 fast ethernet is enough id go for the REV C, if GbE is required a bluesteal GbE board may be in order
Jul 16 01:05:43 <m_billybob> any more than sinle core 1Ghzneed we're talking wanderboard etc
Jul 16 01:06:52 <m_billybob> wanderboard we're talking quad core 2 GB ram but they're also 4x as much in cost
Jul 16 01:06:59 <Geo> yeah
Jul 16 01:07:10 <Geo> not looking to break the bank here
Jul 16 01:07:22 <Geo> what about hummingboard?
Jul 16 01:07:25 <Geo> i2ex
Jul 16 01:07:39 <Geo> what are the pros/cons compared to the bbb?
Jul 16 01:07:48 <m_billybob> im sure the BBB could fit the bill even if you *had* to do distributed processing
Jul 16 01:08:00 <m_billybob> not familiar with that board
Jul 16 01:09:26 <m_billybob> if it's similar to the cubie board quads or duals with 1 GB or more memory. Of course the BBB will be slower since it only has one core t work with and 512 MB ram. but for what it is the BBB is a beast
Jul 16 01:09:42 <m_billybob> sorry for  the typos im eating dinner . . .
Jul 16 01:10:11 <Geo> haha, no worries
Jul 16 01:10:38 <Geo> you're doing much better than many people normally I interact with on IRC
Jul 16 01:11:29 <Geo> I know there is more to these boards than just #cores and memory, just wondering what it is i'm not thinking of here
Jul 16 01:11:38 <m_billybob> sad commentarythat, especially considering i've already had a "40" this eventing ;)
Jul 16 01:11:53 <Geo> but it seems like the straight numbers are a good indicator on these embedded systems
Jul 16 01:12:15 <m_billybob> pound for poind or Hmz vs Mhz id say its as good as any intel processor
Jul 16 01:12:20 <m_billybob> its definately not slow
Jul 16 01:12:45 <m_billybob> and yeah lol that'd be the beer kicking in
Jul 16 01:12:50 <Geo> ha
Jul 16 01:13:13 <m_billybob> anyhowive been playing with 2 BBB's since prerelease last year, and yeah I think they're very nice
Jul 16 01:13:53 <m_billybob> and I really like the fact thatdebian runs on it . . .but thatsa personal preference thing
Jul 16 01:16:18 <Geo> I don't suppose you know of any traffic generator programs, that can gen up network data from multiple IPs?
Jul 16 01:16:36 <Geo> I'd like to try and stress test this a bit, but not sure how to do that in a lab environment
Jul 16 01:16:48 <m_billybob> Geo, also if you're still unconvinced, hel buy one for ~$50 and give it a go worst case, you have code to run on the next system you choose, AND its one hell of an embedded system. Runs Kylie linux well from what i understand
Jul 16 01:16:50 <m_billybob> \
Jul 16 01:17:00 <m_billybob> No im not exatly a network guru sorry
Jul 16 01:19:19 <m_billybob> I have seen people complain that it doesnt run X + x.y.z browser well but . . . this isnt exactly a PC we're talking about
Jul 16 01:19:41 <m_billybob> it also wont handle video as well asa rPI but yeah thats aboutthe only thing the rPI hason the BBB
Jul 16 01:19:49 <Geo> yeah, thats all bells and whisltes as far as I'm concerned
Jul 16 01:19:52 <Geo> I never leave CLI
Jul 16 01:20:03 <m_billybob> glad we're in agreement ;)
Jul 16 01:20:10 <m_billybob> for multiple reason to boot ;)
Jul 16 01:21:58 <m_billybob> oh and yeahsorry forgot to mention the BBB also has what they call PRU"s on them. Basically think two cortex M0+'s that can run real tiem code ( 200Mhz ), and can be programmed to do a multitude of things
Jul 16 01:22:14 <zmatt> the video-thing makes sense, for that you'd want some part that starts with 'dm' rather than 'am'
Jul 16 01:23:15 <m_billybob> plus you'd need someone to support such hardware in software . . . whcih hasnt exactly ben a priority to TI it seems. Something I personally dont . wont miss
Jul 16 01:23:36 <zmatt> I know all too well... our board has a dm814x... *sigh*
Jul 16 01:23:43 <m_billybob> like Geo there for somethignt like this i wont leave CLI
Jul 16 01:24:09 <m_billybob> lol seems my BNC took a nose dive
Jul 16 01:24:48 <zmatt> (latest official kernel from TI for dm81xx is 2.6.37 )
Jul 16 01:25:02 <m_billybob> lol
Jul 16 01:25:03 <zmatt> (no device tree, hardcoded board def)
Jul 16 01:25:07 <m_billybob>  we have RCN  ;)
Jul 16 01:25:17 <m_billybob> hi rcn-ee :P
Jul 16 01:26:22 <zmatt> I wonder what happened to the dm811x / c6a811x though... or the whole c6-integra series for that matter, it seems to have vanished
Jul 16 01:26:53 <m_billybob> Why does that sound familiar
Jul 16 01:27:09 <zmatt> which sucks, since we needed arm + dsp, not all that video crap that's undocumented and holding back the kernel dev
Jul 16 01:27:22 <m_billybob> Anyhow i have a bit ofwork to do outside ill be back in a bit
Jul 16 01:27:28 <zmatt> (I'd gladly sacrifice the video shit for a PRUSS)
Jul 16 01:27:45 <zmatt> though apparently dm811x has both
Jul 16 01:27:51 <m_billybob> Geo, good luck feel free to ask more question, il answer when i get back which may be an hour or slightly more
Jul 16 01:28:14 <m_billybob> PRU's can *do* video . . . anyyhow bbl
Jul 16 01:28:38 <zmatt> m_billybob: not like what the video subsystems of the 81xx series can
Jul 16 01:29:06 <zmatt> like real-time encoding of multiple H.264 HD streams
Jul 16 01:40:11 <Geo> thanks m_billybob
Jul 16 01:40:14 <Geo> for everything
Jul 16 02:08:04 <m_billybob> Geo,  np
