Jun 13 06:49:21 <Dennis_> Hello - did someone know where i can find cheap jtag header for the bbb?
Jun 13 06:50:29 <_av500_> the actual pin header?
Jun 13 06:51:55 <Dennis_> The 20-pin header that i can connect my XDS100v2
Jun 13 06:52:17 <_av500_> right
Jun 13 06:53:15 <_av500_> http://www.tincantools.com/JTAG/BeagleBone-Black-JTAG-Adapter-Kit.html
Jun 13 06:53:19 <_av500_> but pricey
Jun 13 06:53:29 <_av500_> maybe ask them if they can sell you only the header
Jun 13 06:53:55 <_av500_> http://www.digikey.com/product-detail/en/FTR-110-03-G-D-06/FTR-110-03-G-D-06-ND/2651173
Jun 13 06:54:48 <Dennis_> Thanks! :)
Jun 13 06:54:51 <_av500_> or just get a std .1" header and solder that carefully
Jun 13 06:55:03 <_av500_> dont thank me
Jun 13 06:55:05 <_av500_> https://www.google.com/search?q=beaglebone+jtag+header
Jun 13 06:55:10 <_av500_> thank larry and sergey
Jun 13 06:55:58 <_av500_> yeah, solderin a std 0.1" looks simple
Jun 13 06:59:57 <Dennis_> Okay :)
Jun 13 10:12:51 <sumit_> is 2013.04-dirty same as 2013.04..?
Jun 13 10:13:33 <sumit_> is (u-boot-2013.04-dirty) same as (u-boot-2013.04)..?
Jun 13 10:27:51 <prem_> hello frnds, my beaglebone shows "[15808.879384] systemd-journald[93]: Failed to write entry, ignoring: Cannot allocate memory" error when my program runs and the program tries to insert a sql rows to db. How can i avoid this error /
Jun 13 10:29:05 <foobarfreak> Hi, i'm trying to find out how heavliy customized the BBB kernel is? Can I use stock linux kernels on the BBB?
Jun 13 10:29:35 <tbr> yes, vanilla runs
Jun 13 10:30:04 <foobarfreak> oh that is awesome.. so what is the kernel repo for on github?
Jun 13 10:30:18 <tbr> I said _vanilla_
Jun 13 10:32:21 <tbr> https://www.kernel.org/ if this wasn't obvious
Jun 13 10:33:03 <foobarfreak> I get that, thank you
Jun 13 10:35:09 <foobarfreak> I was just wondering what the patch stuff on https://github.com/beagleboard/kernel does ? is that suggested to use or are there no stability issues with vanilla
Jun 13 10:36:28 <tbr> it depends on what you want. I don't know the current state of vanilla
Jun 13 10:39:03 <foobarfreak> ok, well I was using a raspberry pi for some hacking and got bitten by kernel crashes.. which is frustrating because they are maintaining their own kernel fork and it's hard to tell if its an upstream or fork problem. So the reason for asking was to find out if the BBB looks more promising in this regard (from what I can tell it does).
Jun 13 10:41:28 <foobarfreak> but i looks like the patches are pretty straightforward - thanks a lot tbr
Jun 13 10:44:02 <tbr> I haven't looked but would expect the diff to be getting smaller
Jun 13 10:44:45 <foobarfreak> it seems like that.. the patchset for 3.14 is smaller than 3.12
Jun 13 11:50:08 <Rotti> hi
Jun 13 15:22:58 <johann> hi i have a question one can who German 2 as I over clocke my BeagleBone black
Jun 13 15:24:02 <woglinde> what?
Jun 13 15:24:23 <johann> hello?
Jun 13 15:24:54 <johann> yes i want overclock my bbb
Jun 13 15:25:49 <woglinde> why?
Jun 13 15:25:54 <woglinde> playing doom3?
Jun 13 15:26:01 <woglinde> loosing waranty?
Jun 13 15:26:07 <johann> someone has an idea how to do that? 'm actually raspberry pi user :)
Jun 13 15:26:29 <vagrantc> you just want to overclock for the sake of overclocking?
Jun 13 15:26:43 <pjustice> immerse in ln2? :)
Jun 13 15:26:55 <johann> the warranty does not matter it got from my company gifted
Jun 13 15:27:54 <woglinde> you do not need to overclock it, it has already more power than a rpi
Jun 13 15:29:03 <johann>  well I got my rpi 1100 cpufreq
Jun 13 15:29:36 <woglinde> well my has 20 inches still growing
Jun 13 15:31:24 <johann> has really nobody an idea?
Jun 13 15:33:58 * vvu kinda hates ntp on BBB
Jun 13 15:34:20 <woglinde> vvu why?
Jun 13 15:34:26 <woglinde> install openntp
Jun 13 15:34:51 <vvu> i just pushed some stuff to my git and it says "vvu authored 29 days ago" :)
Jun 13 15:35:02 <woglinde> haha
Jun 13 15:35:25 <vvu> well it likes to play games
Jun 13 15:35:57 <agmlego> johann: We are still mostly curious as to why you need to overclock the bone.
Jun 13 15:36:11 <agmlego> johann: Seeing as it runs at 1GHz nominal already...
Jun 13 15:36:20 <woglinde> agmlego -> 17:29 < woglinde> well my has 20 inches still growing
Jun 13 15:37:07 <ogra_> agmlego, else the PS4 emulator wont run smoothly ...
Jun 13 15:37:40 <johann> agmeglo  its a projelt for bio sensors
Jun 13 15:38:22 <woglinde> why a bio sensor needs overclocking?
Jun 13 15:38:28 <woglinde> never heard of such
Jun 13 15:38:36 <vvu> superBioComputing w00pw00p
Jun 13 15:39:46 <johann> the processing of the sensor takes a bit too long it would fit something around 1200 mhz
Jun 13 15:40:01 <xD1845> any of you guys used ODROID?
Jun 13 15:40:29 <agmlego> johann: And you ahve tested the bone with this sensor and determined that it is too slow?
Jun 13 15:40:54 <agmlego> johann: Or are you basing this solely off the Pi, which is a different processor entirely and bears little on the bone's performance?
Jun 13 15:41:42 <woglinde> hm he did not say he used the sensor on the pi
Jun 13 15:41:57 <agmlego> No, he did not.
Jun 13 15:42:30 <johann> yes and no an ex employee that had project and he has only geschaft he went out for personal reasons of the company away he said to me overclocking is the magic word
Jun 13 15:42:35 <woglinde> but I wonder how he can forseen that extra 200 mhz solves the problem
Jun 13 15:42:44 * woglinde has doubts
Jun 13 15:43:03 <agmlego> johann: So, I would say just go try it then on the bone and see if you actually have a performance issue.
Jun 13 15:43:25 <agmlego> johann: Besides, what is your analysis software written in? It may be that you could just optimize that and get better results.
Jun 13 15:43:29 <woglinde> I would say fix the software and use a dsp
Jun 13 15:43:38 <woglinde> agmlego *5*
Jun 13 15:45:13 <johann> the processing of the inputs are 25 sensors are too slow for that he is a bit too slow you go to the
Jun 13 15:45:40 <woglinde> I smell the pru
Jun 13 15:45:42 <agmlego> johann: THat sentence did not make sense. Could you try to rephrase?
Jun 13 15:46:01 <woglinde> PRU for world domination
Jun 13 15:46:31 <johann> sorry my english is very bad: (
Jun 13 15:47:09 <woglinde> hm not so good for getting into software and programming
Jun 13 15:47:09 <johann> he is a litllbit to slow for 25 sensors  that is the point
Jun 13 15:47:30 <woglinde> I wonder how you can connect 25 sensors to the bone
Jun 13 15:47:43 <johann> I know, unfortunately, that makes a well-known company in the thank god
Jun 13 15:47:50 <agmlego> johann: How do you know it is too slow if you have not tried it yet?
Jun 13 15:48:06 <woglinde> hi rcn
Jun 13 15:48:17 <agmlego> johann: What interface are the sensors connected to?
Jun 13 15:48:32 <rcn-ee> howdy woglinde
Jun 13 15:48:35 <johann> cables by about 80 and 1 booster focus the signal
Jun 13 15:48:42 <woglinde> agmlego I fear he got the task to overlock the bbb
Jun 13 15:48:46 <woglinde> nothingmore
Jun 13 15:49:11 <johann> its correct woglinde
Jun 13 15:49:15 <agmlego> johann: ...that means nothing to me. What protocol are the cables? I2C? SPI? UART? Ethernet?
Jun 13 15:50:00 <woglinde> agmlego forget it
Jun 13 15:50:05 <woglinde> he has no inside
Jun 13 15:50:05 <johann> Ethernet ^^
Jun 13 15:50:19 <woglinde> simple task overclock the bbb
Jun 13 15:50:28 <woglinde> than goback to configure mailserver
Jun 13 15:50:30 <agmlego> Right, but that is probably the wrong solution.
Jun 13 15:50:56 <woglinde> agmlego we can not change it he can not change it company will blow up at some point
Jun 13 15:51:28 <agmlego> johann: I still strongly recommend actually trying to run your analysis software and sensors on the bone and see if you actually have a problem.
Jun 13 15:52:11 <johann>  only it is my job and if that goes wrong in the work, it is also not my problem
Jun 13 15:52:22 <agmlego> johann: If you have a problem with performance, *then* I would say investigate eithe roverclocking, but the better solution would be seeing if you can optimise the analysis software, or offload some of the analysis to a different processor like a dedicated DSP.
Jun 13 15:52:54 <agmlego> johann: Because just blindly overclocking something with no proof that it is needed is pretty much the worst thing a human being can do.
Jun 13 15:54:36 <johann>  yes i can not help it I got the job in my work more now because I can not say unfortunately, I personally would not do it but my boss wants it and if he even explode with the rem last it with me :)
Jun 13 15:56:01 <agmlego> Well, then I suggest getting the AM335x reference manual and seeing what registers you need to play with to adjust the clock settings.
Jun 13 15:56:37 <woglinde> I would normaly quit such company
Jun 13 15:57:18 <agmlego> Not like jobs are hard to find these days.
Jun 13 15:59:08 <johann> So nobody knows how to do it?
Jun 13 15:59:55 <myself> apparently not.
Jun 13 16:00:26 <agmlego> johann: THe people who made the chip and wrote the reference manual know how to do it.
Jun 13 16:00:27 <johann> xD
Jun 13 16:00:37 <agmlego> johann: Which is why I referred you to the manual.
Jun 13 16:00:48 <agmlego> johann: Which should tell you how to do it.
Jun 13 18:50:39 <bzyx> hi, what is the voltage on serial (UART1) of begaleboard-xm
Jun 13 18:51:22 <foreverska> 3.3v?
Jun 13 18:51:55 <rcn-ee> the xm has a pc-serial connector, so not ttl..
Jun 13 18:53:51 <Aston> how can i install ros on debian on the beaglebone black
Jun 13 18:54:18 <bzyx> the i can't find it on the trm, only fact I've found is that UART2 on expansion is 1.8V
Jun 13 18:54:56 <bzyx> but as my 3.3 serial cable doesn't works so it's propably 5V I guess?
Jun 13 18:55:29 <rcn-ee> bzyx, look at the schematic, there's a rs232 level translater right before the serial connector
Jun 13 18:56:11 <thurgood> should just plug in a standard usb-serial, and as long as you have the drivers on the host it should work
Jun 13 18:56:45 <Aston> can i have some help with a ROS install? i have the Rev C that came with debian. Ubuntu was a little slow for me so i switchedback to debain
Jun 13 18:57:46 <rcn-ee> bzyx, 5.5volts: http://www.ti.com/product/sn65c3221e
Jun 13 18:58:23 <bzyx> rcn-ee: thanks! so that's why all my serial cables doesn't works at all with this board...
Jun 13 18:58:36 <rcn-ee> it's setup to talk to a real pc..
Jun 13 18:59:30 <bzyx> mhm and the other pins are not connected so the supply voltage don't hurt the board
Jun 13 19:00:02 <thurgood> Aston:  sorry, dunno anything about ROS
Jun 13 19:00:45 <Aston> thats alright. Im just wondering, are there any benefits of having a ubuntu install over debian?
Jun 13 19:01:39 <thurgood> amount of stuff preinstalled... if you see that as a plus
Jun 13 19:02:01 <rcn-ee> well, ubuntu eol's in 9 months, unless it's a ltc.. ;)
Jun 13 19:02:34 <thurgood> that can also be a negative, depending on how you look at it
Jun 13 19:02:38 <foreverska> How is that a benefit?
Jun 13 19:02:47 <vagrantc> debian's EOL is typically about 3 years..
Jun 13 19:02:54 <rcn-ee> it pushes more people to debian... aka 'benefit'. .;)
Jun 13 19:02:57 <Aston> thats true. i see that ubuntu runs a lot slower.
Jun 13 19:03:02 <foreverska> lol
Jun 13 19:03:41 <xD1845> USB 3.0 ! I would love some dev board that supports it xD
Jun 13 19:03:51 <Aston> the only thing i got running smooth on ubuntu was ROS but nothing else worked. so i switched back to debian..
Jun 13 19:04:25 <Aston> xD1845: doesnt the new Arndale or something support USB 3? Im not sure
Jun 13 19:04:45 <rcn-ee> there's usb 3.0 on the omap5 uevm..
Jun 13 19:05:02 <xD1845> Is Arndale open hardware?
Jun 13 19:05:20 <xD1845> I would hate to write some software only to realize I can't buy something to spin my own board … cough RPI
Jun 13 19:06:10 <Aston> All i remember is that the ARndale runs a samsung Exynos 5 system
Jun 13 19:06:35 <Aston> xD1845: http://www.arndaleboard.org/wiki/index.php/Main_Page
Jun 13 19:06:36 <xD1845> Aston: Is that something I can purchase?
Jun 13 19:07:07 <Aston> xD1845: yes you can
Jun 13 19:07:25 <xD1845> Hmm
Jun 13 19:07:34 <Aston> Check the link i provided
Jun 13 19:07:36 <xD1845> Do they have restrictions like the Broadcom chip?
Jun 13 19:07:52 <Aston> That im not sure. Do have a look at their website
Jun 13 19:08:40 <thurgood> no stock at the moment is what the distributor's site says
Jun 13 19:08:43 <xD1845> I worked on a camera interface application on the RPI, went to go remake a smaller board, and ran into the BCM2835 issue.
Jun 13 19:09:09 <rcn-ee> unless your a big oem, with a big order, you'll run into that same issue with exynos..
Jun 13 19:09:34 <xD1845> Just a kid working on hobby like projects
Jun 13 19:09:35 <xD1845> Lol
Jun 13 19:09:40 <Aston> i came across a lot of boards, here are some names. odroid, radxa, Parallella
Jun 13 19:09:58 <Aston> there is also a banana pi :P
Jun 13 19:10:02 <thurgood> plus it's nearly a $500 board
Jun 13 19:10:04 <xD1845> ODROID makes a module for the samsung chip that you can buy from them, but it doesn't support USB 3.0
Jun 13 19:10:26 <Aston> nope usb 2. but you get a fast cpu. quad exynos 4
Jun 13 19:11:09 <Aston> and they have their own webcam modules and stuff.. and its ony $64
Jun 13 19:12:20 <thurgood> oops 450+ was the octaboard
Jun 13 19:12:52 <Aston> yup the arndale was 299+ and the odroids have a lot cheaper versions
Jun 13 19:13:11 <xD1845> true
Jun 13 19:13:16 <xD1845> I was going to get an ODROID
Jun 13 19:13:32 <xD1845> Another project I was looking into would really need an USB 3.0 interface though :]
Jun 13 19:13:41 <thurgood> the plain quadcore version is around 250
Jun 13 19:13:42 <Aston> I have a suggestion
Jun 13 19:13:51 <Aston> give me a moment to get the links
Jun 13 19:13:55 <xD1845> Ok
Jun 13 19:14:22 <Aston> Look at this http://cubox-i.com/products/
Jun 13 19:14:36 <xD1845> Hummingboard!?
Jun 13 19:14:50 <Aston> they have small linux computers that are really fast and not that expensive. You can alwasy do a PIC for GPIO if you need
Jun 13 19:14:57 <rcn-ee> xD1845, there's usb 3.0 on the omap5, https://www.isee.biz/products/igep-processor-boards/igepv5-omap5432
Jun 13 19:14:59 <Aston> no. this is the cubox-i
Jun 13 19:15:47 <thurgood> I thought omap5 was discontinued?
Jun 13 19:16:25 <Aston> I think they are still developing for applications other than smartphone
Jun 13 19:16:49 <thurgood> ah, that makes some sencse
Jun 13 19:16:53 <xD1845> Wow
Jun 13 19:17:00 <xD1845> That ISEE board looks sweet
Jun 13 19:17:07 <rcn-ee> the people "working" on it were discontinued.. It's alive in a few products. https://www.svtronics.com/omap/omap54xx?product_id=33
Jun 13 19:17:23 <xD1845> I wonder how the support is for it, such as software/drivers
Jun 13 19:17:33 <Aston> Ah that sounds better.
Jun 13 19:18:25 <rcn-ee> sata missed the v3.16.x merge, video/usb just started working on mainline,
Jun 13 19:18:49 <xD1845> Last year I started working on an app for the RPI that used the camera interface, it was pretty easy getting the software functioning due to all of the hardware support
Jun 13 19:19:06 <xD1845> Decided to make a "smaller" version, and found out that it wasn't possible
Jun 13 19:19:18 <xD1845> Switched to beagle, trying out a camera cape so far
Jun 13 19:37:36 <treeherder> hi guys
Jun 13 19:37:48 <treeherder> so im back  with my emmc troubles
Jun 13 19:38:06 <treeherder> if you all remember i accidentally fdisked my emmc
Jun 13 19:38:22 <rcn-ee> reflash it. ;)
Jun 13 19:38:40 <treeherder> and  for some reason, when I try a regular (non emmc-flashing) image boot from the SD, it errors out and doesn't boot
Jun 13 19:38:49 <treeherder> but when i put an emmc-flashing image in
Jun 13 19:38:53 <treeherder> it boots to a desktop
Jun 13 19:39:08 <treeherder> and then i get the "this is justa  temporary desktop" deal
Jun 13 19:39:32 <treeherder> and then all  four lights start flashing at the same time 2x quickly with a longer pause betwen ech set of 2
Jun 13 19:39:43 <treeherder> and i went to bed assuming it wouldflash last night
Jun 13 19:39:49 <treeherder> and it's still doing exactly that
Jun 13 19:39:52 <treeherder> 11 hours later
Jun 13 19:40:00 <treeherder> on a BBB this is
Jun 13 19:40:41 <treeherder> so should i be doing something differently?
Jun 13 19:41:34 <rcn-ee> sounds like you are doing correct.. give my 'updated' flasher a try: http://elinux.org/BeagleBoardDebian#eMMC:_BeagleBone_Black (should only take 10 minutes, i'm rolling that into the offical release)
Jun 13 19:42:10 <treeherder> awesome thanks for the tip
Jun 13 19:42:14 <treeherder> will report back
Jun 13 19:44:48 <rcn-ee> (and everything is logged to the serial, so it's easier to debug issues. ;) )
Jun 13 19:56:49 <treeherder> rcn-ee, should this be booting past the kernel module messages?
Jun 13 19:56:53 <treeherder> oh look it is
Jun 13 19:57:14 <treeherder> i asked too soon!  it just told me there's an unkown partition table
Jun 13 19:57:24 <treeherder> i think it might try to fix it
Jun 13 19:59:12 <treeherder> the lights are lighting up sequentially so it looks like pong or something, I assume that's good?
Jun 13 19:59:16 <rcn-ee> i just blow the partition table away right away: https://github.com/RobertCNelson/boot-scripts/blob/master/tools/init-eMMC-flasher.sh#L251 the old flasher could get stuck if you were a little to creative..
Jun 13 19:59:37 <treeherder> you're awesome
Jun 13 19:59:54 <treeherder> thanks for this, it seems much more likely to succeed
Jun 13 20:00:05 <treeherder> i was worreid i'd bricked it
Jun 13 20:00:12 <rcn-ee> what's the world coming to!! It's a cylon led pattern! ;)
Jun 13 20:00:24 <treeherder> be back in 10-20 after some tea, and update you
Jun 13 20:16:02 <treeherder> it worked!  you are a shining golden god, rcn-ee
Jun 13 20:16:24 <treeherder> thank you
Jun 13 20:56:00 <foreverska> I can just put a varistor between the ADCv and one of the ADC inputs right?
Jun 13 21:43:08 <treeherder> how do i tell which rev BBB i have?
Jun 13 21:43:45 <foreverska> Wisper to it, "Tell me your secret o beagle of the board"
Jun 13 21:43:53 <treeherder> i tried that
Jun 13 21:44:04 <treeherder> and some *favors*
Jun 13 21:44:18 <treeherder> but it was not swayed to reveal its secrets
Jun 13 21:44:25 <foreverska> Is it black (I promise that's not racist)
Jun 13 21:44:37 <treeherder> yes it's black
Jun 13 21:44:50 <treeherder> fits in an altoids box
Jun 13 21:45:25 <foreverska> I want to say it's printed on the board but mine is in a rat's nest of wires I don't want to unhook
Jun 13 21:46:39 <rcn-ee> well, if it has a 4GB eMMC, then it's a C..
Jun 13 21:47:16 <bzyx> you can look at the box too, it's printed on it
Jun 13 21:47:20 <foreverska> eMMC are for punks
Jun 13 21:47:43 <rcn-ee> punks who can't read the label. ;)
Jun 13 21:48:12 <foreverska> Well you can't blame the punks.  It's usually a parenting issue with them...
Jun 13 21:48:16 <treeherder> i don't have box
Jun 13 21:48:25 <treeherder> i picked it up out of a free pile
Jun 13 21:48:50 <foreverska> Why do you really need to know?  All the blacks are pretty close in specs...
Jun 13 21:49:03 <foreverska> That sounds so bad...
Jun 13 21:49:23 <treeherder> i was more curious than anything
Jun 13 21:49:36 <foreverska> Probably B
Jun 13 21:49:43 <treeherder> and you can stop with the racial jokes, it doesn't sound bad until you  say it
Jun 13 21:50:38 <foreverska> What are you talking about?  I meant there are specific differences in the black models that do make a difference but I'm just sort of generalizing them...
Jun 13 21:51:08 <treeherder> [14:44:27] <foreverska> Is it black (I promise that's not racist)
Jun 13 21:51:21 <treeherder>  All the blacks are pretty close in specs...
Jun 13 21:51:21 <treeherder> [14:49:04] <foreverska> That sounds so bad...
Jun 13 21:51:24 <treeherder> that's not the same joke?
Jun 13 21:51:36 <treeherder> you couuld just say "ok" or "sorry" instead of being a coward about it
Jun 13 21:51:40 <treeherder> at least own up to it
Jun 13 21:51:44 <foreverska> lol
Jun 13 21:51:49 <treeherder> anyways thanks for your help
Jun 13 22:01:17 <aleandros> Hi people! Stupid question here. On the Beagleboard 101 website, almost at the end, it reads: "If the eMMC is not placed in reset, the MMC1* signals may bot be used..."
Jun 13 22:01:36 <aleandros> what does "place in reset" mean, concerning the eMMC?
Jun 13 22:31:55 <foreverska> Surely theres a memory interface for the ADC...
Jun 14 00:12:25 <dogrocket> anyone know i2s connections?  wondering if din goes to din on other device or is it din to dout
Jun 14 00:12:53 <dogrocket> dumb question i know but lrclk goes to lrclk
Jun 14 00:18:51 <mrpackethead> its a bus
Jun 14 00:19:11 <mrpackethead> and i assume you mean i2c?
Jun 14 00:55:10 <dogrocket> nope i2s, theres a din and dout pin on beagle and din dout on codec...   not sure im guessing din goes to dout
