May 21 04:50:05 <foreverska> Why can't I store stuff to dataram>
May 21 04:52:08 <av500> ?
May 21 04:53:05 <foreverska> I SBBO the contents of R31 to 0x0 (0 offset 4 bytes) and it does nothing.
May 21 04:55:02 <av500> ?
May 21 04:56:02 <foreverska> I'm guessing you're not familiar with the PRU sub system...
May 21 05:00:10 <av500> indeed
May 21 05:25:00 <foreverska> It's insane... I feel like an idiot because I can't access its own local memory... not read, not write, nothing
May 21 11:53:03 <akoori> hi guys
May 21 12:56:20 <upwardindex> I’m following http://elinux.org/BeagleBone_Black_Enable_SPIDEV but I cannot find the file /sys/devices/bone_capemgr.* I’m running RCN’s 3.14.4
May 21 13:13:35 <heeen> what is the ocp master port
May 21 13:14:27 <upwardindex> Oh, looks like device tree overlays are a thing of the past. Too bad they seemed very convenient.
May 21 13:15:34 <jkridner> upwardindex: how so?
May 21 13:15:36 <jkridner> you mean with all the universal overlays?
May 21 13:16:00 <Humpelstilzchen> upwardindex: source?
May 21 13:16:09 <upwardindex> https://groups.google.com/forum/#!msg/beagleboard/Mff1dl1GuAc/CFpOz2FnO2IJ
May 21 13:17:22 <av500> so?
May 21 13:18:25 <jkridner> yeah, I don't see anything there that says devicetree overlays are going away.
May 21 13:18:46 <jkridner> they aren't yet part of mainline, but panto has been working on getting his code accepted.
May 21 13:19:11 <jkridner> more options is more options.
May 21 13:19:34 <upwardindex> How do you load them in 3.14 ?
May 21 13:19:46 <KotH> jkridner: especially as panto is still trying to get them into mainline
May 21 13:20:15 <jkridner> KotH: thought I just said that. ;-)
May 21 13:21:19 <KotH> jkridner: sorry... i'm too slow reading
May 21 13:21:24 <KotH> jkridner: severe lack of chocolate
May 21 13:23:35 <jkridner> #beagle needs more chocolate.
May 21 13:24:03 <KotH> the #world needs more chocolate
May 21 13:27:54 <akoori> hi everyone, i received my rev c element 14 beagle bone today and havent been able to connect to it. it is not even appearing as a drive on either my mac or my linux machine. any ideas? the lights indicate that it is on and booted i just dont have a micro hdmi cable to see what is going on
May 21 13:36:51 <jkridner> akoori: an FTDI 3.3V serial cable would help.
May 21 13:37:08 <jkridner> if not even showing up as a flash drive, that is quite odd. did you wait a while?
May 21 13:37:16 <jkridner> you might try reflashing it.
May 21 14:02:12 <upwardindex> I’m really confused with the defconfig provided by RCN. For example in 3.8 CONFIG_HZ is 512, in 3.11 it is 100, in 3.12 it is 250, in 3.13+ it is back to 100. Any idea why?
May 21 15:52:36 <upwardindex> What is wrong with this: `dtc -I dts -O dtb -o test.dtb am335x-bone.dts` ?
May 21 15:55:49 <vagrantc> upwardindex: nothing looks wrong with that to me... do you get an error?
May 21 15:57:55 <upwardindex> vagrantc: Yes, what appears to be the single error that dtc is able to spew out: FATAL ERROR: Unable to parse input tree
May 21 15:58:08 <upwardindex> at the first include directive
May 21 15:58:35 <vagrantc> upwardindex: is am335x-bone.dts a complete dts file, or does it have a bunch of includes?
May 21 15:58:38 <H-H-H> there is an error in the .dts file
May 21 15:59:27 <upwardindex> It has two includes, it’s the unmodified file from RCN’s 3.14 kernel
May 21 15:59:54 <upwardindex> It builds fine using make […] dtbs
May 21 16:00:39 * vagrantc suspects the includes aren't handled by dtc.
May 21 16:00:52 <vagrantc> look at what make is doing and replicate that...
May 21 16:02:07 <upwardindex> I’m trying to figure what make is doing, however I’m a bit lost in all the makefiles.
May 21 16:16:07 <upwardindex> Ok, well the line I used is not even close to how we compile a dtc, first you call gcc, then dtc, fixdep, gcc, dtc and finally cat some stuff
May 21 16:17:58 * vagrantc wonders if you could get away with just catting stuff and then calling dtc
May 21 18:40:27 * nyt yawns
May 21 18:40:27 <nyt> morning
May 21 18:40:28 <nyt> ish
May 21 18:51:42 <Steve___> What are the US export rules on the Beaglebone Black?
May 21 18:52:40 <rob_w> Steve___,  ?
May 21 18:53:03 <rob_w> pay the price , i guess , there will be ways to serve you in any country ;-)
May 21 19:33:45 <mistawright> hi guys i need some help
May 21 19:49:02 <nyt> maybe you want to elaborate
May 21 19:51:42 <foreverska> Have you tried turning it off and on again mistawright?
May 21 19:54:54 <rob_w> :-)
May 21 20:01:18 <jonand> good evening. I'm running a beagle-xM + ubuntu 14.04 (linux 3.13.3) and I seem to get a different hw mac address on eth0 every time I boot, which screws my "static" dhcp assignment. Any hint on what I have messed up?
May 21 20:03:08 <myself> no idea, but pastebin your boot log or dmesg for others to pore over
May 21 20:03:44 <jonand> myself: I'll do that, thanks.
May 21 20:04:26 <honestly> jonand: put a hwaddress line into /etc/network/interfaces
May 21 20:08:42 <jonand> honestly: aaah, thanks, there was an example commented out there already! guess my google karma isn't very good today. reboot was probably the missing keyword.. thanks a lot!
May 21 20:09:05 <jonand> #hwaddress ether DE:AD:BE:EF:CA:FE :)
May 21 20:09:34 <honestly> I'd recommend making it start with 00:42:
May 21 20:15:41 <foreverska> Honestly, If you wouldn't mind what's your reasoning behind that?
May 21 20:16:29 <honestly> that's what I use and I know it's a valid hardware address for NICs
May 21 20:16:51 <honestly> I don't know the full range or rules
May 21 20:16:55 <honestly> but I know 00:42: works
May 21 20:17:09 <foreverska> gotcha
May 21 20:24:39 <jonand> honestly: as long as you stay out of FF-ish (broadcast) or 01:80: (multicast) you are pretty safe... I have an old lab range reserved for me so I stick to that by habit.. :)
May 21 20:25:27 <Daniel___> Hello - I'm new in working with the BeagleBone Black which I got today :) - I want to run a realtime os for example xenomai?? Is there anyone who already worked or ported xenomai to the Beaglebone Black? It would be fine if there is someone who can tell me something about that - thanks!
May 21 20:25:59 <honestly> the beaglebone isn't meant to run a RT os
May 21 20:26:05 <honestly> it has the PRU to do realtime tasks
May 21 20:26:11 <myself> Daniel___: tell us first about the results of your google searches in that topic
May 21 20:26:57 <myself> jonand: the lsb of the high byte has significance, It's a multicast indicator.
May 21 20:27:24 <Daniel___> Google tells me http://brunosmartins.info/xenomai-on-the-beaglebone-black-in-14-easy-steps/ but i tried this tutorial but it doesnt work and could find a failure
May 21 20:28:49 <jeremyagost_> hey guys, is there a place that hosts older beaglebone linux images?
May 21 20:29:11 <Daniel___> I never programmed a PRU :( I'm a total beginner maybe u have ssome nice docs which i can read?
May 21 20:29:13 <jeremyagost_> specifically I’m looking for the angstrom distro based on kernel 3.2.34
May 21 20:30:57 <jeremyagost_> the image revision is “BeagleBone A6A Image 11.22.2012"
May 21 20:33:32 <thurgood> jeremyagost_: have you looked at circuitco's site?
May 21 20:34:55 <jeremyagost_> thurgood: doesn’t seem to be much there
May 21 20:38:55 <jeremyagost_> I eventually found it
May 21 20:39:02 <jeremyagost_> elinux.org
May 21 20:39:35 <thurgood> http://beagleboard.org/latest-images ?
May 21 20:40:00 <thurgood> it's more recent, but should work with the white
May 21 20:40:56 <jeremyagost_> yeah the latest works, but I need one based on the 3.2.34 linux kernel
May 21 20:41:12 <jeremyagost_> as well as one that has the network gadget service
May 21 20:41:40 <jeremyagost_> for whatever reason I can’t load the ethernet driver kernel module on the latest image with my white
May 21 20:42:04 <thurgood> good reason to stick w/ 3.2 :)
May 21 20:42:15 <jkridner> jeremyagost_: hmmm.... looking for http://elinux.org/Beagleboard:BeagleBone_A6A_Image_11.22.2012 ?
May 21 20:42:27 <jeremyagost_> jkridner: thanks, yeah eventually found a link to download the image
May 21 20:43:00 <jeremyagost_> seems like 3.8 broke everything :(
May 21 20:43:05 <jkridner> oh, k. I have a bunch of old ones mirrored on S3 if you didn't have it.
May 21 20:43:46 <jeremyagost_> happens to be on this page http://www.elinux.org/Beagleboard:BeagleBone#Revision_A6A_Image
May 21 20:45:38 <myself> oldversion.com? ;)
May 21 21:14:04 <foreverska> Anyone know the switch voltage for a digital input?
May 21 21:14:40 <nyt> 3.8 works best for me over the others
May 21 21:28:59 <fishfryfood> Can anyone provide a link to resource that can help with trimming down the angstrom packages? For example as I'm using it headless I don't need any desktop stuff.
May 21 21:29:16 <fishfryfood> I just find it confusing what i can dump, and what I need to keep
May 21 21:30:04 <H-H-H> thats one of the reasones i run arch/manjaro on my bbw
May 21 21:30:38 <fishfryfood> interesting
May 21 21:31:55 <H-H-H> bah i need some I2C level shifters anyone got any good suggestions of where to get a few?
May 21 21:33:26 <veremit> fishfryfood .. I think if it were me, I'd probably wipe the beagle clean and work up rather than down ..
May 21 21:34:07 <H-H-H> build your own system starting with uboot then a kernel and whatever init system you prefer :)
May 21 21:34:09 <veremit> you're likely to end up with weird spare dependencies and stuff if you find the -right- packages to remove :)
May 21 21:34:27 <veremit> if you don't .. well . lol
May 21 21:34:42 <fishfryfood> we'll thanks for the thoughts.
May 21 21:35:54 <veremit> might seen brutal .. but you'll probably learn some useful stuff along the way :)
May 21 21:36:23 <fishfryfood> that's true, that would be a sure fire way to fill in some knowledge gaps I have on linux. Doesn't sound very fun though :-p
May 21 21:36:28 <H-H-H> like device tree overlays lol them things are evil
May 21 21:37:05 <veremit> naaa . DTB's are ok unless you wanna go nuts with custom peripherals .. which IS cool .. but pretty hard-core too :)
May 21 21:37:39 <jkridner> fishfryfood: per the mailing list, "apt-get remove -y x11-common ; apt-get autoremove" should get rid of much of it.
May 21 21:37:52 <H-H-H> how can i get a custom dtb to load on boot
May 21 21:38:28 <veremit> jkridner .. are the new beagle's starting to ship with debian yet?
May 21 21:38:42 <jkridner> veremit: yup.
May 21 21:38:45 <fishfryfood> apg-get I don't think is present on the agstrum. But i'm sure the equivlent cmds for opkg will do. x11-common sounds liek a good starting spot
May 21 21:38:51 <veremit> H-H-H .. you might need to slide an EEPROM somewhere the cape-manager can find it
May 21 21:39:01 <jkridner> fishfryfood: oh, Angstrom.
May 21 21:39:12 <veremit> lol jkridner .. Yes, Angstrom :)
May 21 21:39:19 <veremit> beloved Angstrom :)
May 21 21:39:21 <fishfryfood> i always want to put a u at the end
May 21 21:39:32 <H-H-H> i thought you could "fake" the eprom as far as the capemanager was concerned
May 21 21:39:35 <jkridner> many of the Angstrom packages have similar names as Debian, but the differences have been growing.
May 21 21:40:03 <jkridner> H-H-H: you can look at uEnv.txt on the FAT file system for some guidance...
May 21 21:40:09 <jkridner> likely includes some comments.
May 21 21:40:19 <jkridner> if not, google for uEnv.txt and capemgr
May 21 21:41:16 <H-H-H> i tried what i found on the web regarding adding a line to uenv but it didnt work
May 21 21:41:20 <veremit> I'm not sure whether there's a way without capemgr
May 21 21:41:25 <H-H-H> but i will continue
May 21 21:41:32 <veremit> sure its the right uEnv? (I've seen two ...!)
May 21 21:41:47 <jkridner> if you are replacing the entire .dtb, there's no way to do that with capemgr.
May 21 21:42:11 <jkridner> u-boot trys to load the .dtb based on the board type it detects.
May 21 21:42:17 <H-H-H> if i load the dtb after the system has booted it loads and works fine
May 21 21:42:19 <jkridner> dtb != dtbo
May 21 21:42:31 <jkridner> H-H-H: so, you mean dtbo, not dtb?
May 21 21:42:42 <veremit> o = overlay, right?
May 21 21:42:49 <veremit> dtb yes gets read by uBoot
May 21 21:42:49 <H-H-H> hold on i will find the tut i tryed
May 21 21:42:53 <jkridner> only one dtb is possible and it is loaded at boot.
May 21 21:42:55 <vagrantc> whatever happened to the "build custom dtb" without cape-manager idea?
May 21 21:42:58 <jkridner> veremit: yeah.
May 21 21:43:08 <jkridner> vagrantc: it is possible, sure.
May 21 21:43:33 * vagrantc recalls some thought about building a frontend for a dtb-builder sort of thing
May 21 21:43:34 <jkridner> vagrantc: not sure what all you and rcn-ee have put in in that regards. :-)
May 21 21:43:57 <vagrantc> not much here, other than thinking it'd work
May 21 21:44:05 <H-H-H> http://hipstercircuits.com/enable-serialuarttty-on-beaglebone-black/
May 21 21:44:07 <veremit> lol
May 21 21:44:34 <veremit> enabling the uarts is easy with capemgr.enable_partno=BB_UART4 or similar
May 21 21:44:40 <veremit> can't remember the exact syntax.
May 21 21:45:10 <fishfryfood> capemgr.enable_partno=BB-UART1
May 21 21:45:48 <fishfryfood> echo BB-UART1 > /sys/devices/bone_capemgr.9/slots
May 21 21:45:48 <H-H-H> im looking to enable them all as i have a few arduinos anda gsm module i want to talk to
May 21 21:46:20 <veremit> just cascade them in a list .. ie. BB-UART1,BB-UART2,BB-UART3, etc
May 21 21:48:55 <H-H-H> thanks guys i will give it a go
May 21 21:49:35 <veremit> good luck
May 21 21:50:20 <H-H-H> after i get my wifi working again
May 21 21:50:34 <veremit> wuh oh .. Not the Wifi .. lol
May 21 21:51:19 <H-H-H> ive had it working before but i since changed to a bigger sd card so re doing everything
May 21 21:51:39 <veremit> dd if=sdcard1 of=sdcard2 bs=1M :D
May 21 21:51:49 <veremit> aaaand Wait lol
May 21 21:51:57 <nyt> cool latest image has the latest version of my library, no need to upgrade anything =]
May 21 21:53:07 <H-H-H> i would have done that but the old card seems to have vanished lol
May 21 21:54:15 <veremit> all merged in now nyt?! :)
May 21 21:58:49 <H-H-H> thats better wifi is back up
May 21 22:25:39 <nyt> veremit: yeah the april images had an earlier version with some bugs =[ may image is golden
May 21 22:25:52 <veremit> cool
May 21 22:39:17 <dogrocket> ugh.. need help figuring out what pins from codec goto what pins on bbb anyone good at that?
May 21 22:40:57 <veremit> not in the reference manual(s) ?
May 21 22:41:00 <dogrocket> using max98089 codec,  should i use the mcasp pins or should i use the pins that come off hdmi?
May 21 22:41:19 <veremit> don't think you can use hdmi pins for codecs?
May 21 22:41:28 <veremit> oh you mean .. the shared ones ..
May 21 22:41:36 <dogrocket> well the shared audio ones yep
May 21 22:42:29 <dogrocket> some instructions on net say this is one way to do it...  but must disable hdmi audio
May 21 22:42:45 <dogrocket> im thinking i should use mcasp pins
May 21 22:50:04 <ds2> has anyone analyzed how noisy the ADC is?
May 21 23:03:29 <dogrocket> anyone know if tdm i2s works ok on beagle?
May 21 23:03:43 <ds2> let me ask it in different manner... anyone interested in the ADC noise characteristics?
May 21 23:04:04 <ds2> dogrocket: don't see why not
May 21 23:05:55 <H-H-H> dogrocket are you making your own audio solution ?
May 21 23:10:43 <nyt> ds2: of course
May 21 23:18:24 <foreverska> Crap... I think my beagle just died
May 21 23:21:00 <H-H-H> awwww :(
May 21 23:21:33 <nyt> <foreverska> Anyone know the switch voltage for a digital input?
May 21 23:21:38 <nyt> wonder why lol
May 21 23:22:07 <foreverska> lol I assumed it was 3.3 but I was wondering how LOW it would go
May 21 23:24:15 <H-H-H> i almost upset my bbw today , i was going to hook up an I2C rtc but totally forgot about the logic levels so almost let the majic smoke out lol
May 21 23:24:31 <H-H-H> lukilly i realized before power was applied
May 21 23:25:07 <H-H-H> my rtc is 5v not 3.3
May 21 23:25:54 <foreverska> Well.. off to radioshack I go I guess...
May 21 23:26:22 <miker> trying to install wifi on my new BBB running Debian
May 21 23:26:54 <miker> cannot find connman. Guess its not in Debian
May 21 23:27:07 <nyt> foreverska: yeah its 3.3v, no idea how low to trigger, get a pot and test =]
May 21 23:27:31 <ds2> nyt: are you good at data analysis?
May 21 23:27:42 <ds2> i.e. you got a easy way to do a FT on a dataset
May 21 23:28:46 <nyt> unfortunately, don't have time at the moment =[ in fact, about to go finish spackling this wall
May 21 23:28:56 <nyt> before the wife gets angered
May 21 23:28:58 <ds2> it won't be now...
May 21 23:29:02 <ds2> probally after memorial wknd
May 21 23:29:14 <ds2> thinking of collecting some data but my matlab skills are rusty
May 21 23:29:20 <foreverska> Well what I was doing was obviously sketchy so I'll copy a known good circuit for what I'm doing... probably should've been my first inclination since I'm not a EE major.
May 21 23:29:34 <ds2> in the time domain, the adc output is down right nasty looking
May 21 23:41:30 <treeherder> what does it mean that when i try to flash my eMMC after a minute all four lights start flashing together very brightly and quickly in 2 pulses
May 21 23:41:35 <treeherder> on the BBB
May 21 23:41:55 <treeherder> and the eMMC never seems to flash
May 21 23:42:38 <H-H-H> ive heard the emmc caN TAKE A LONG TIME IE 10 MINS OR MORE TO FLASH
May 22 00:22:52 <thurgood> emmc /may/ require a barrel connector to flash properly
May 22 00:42:16 <foreverska> Optoisolators don't have a minimum voltage on the switching side do they?
May 22 00:50:24 <ds2> 5

May 22 00:51:23 <H-H-H> 1
May 22 00:51:37 <raspberrypifan> im getting a bone
May 22 00:51:38 <raspberrypifan> in the mail
May 22 00:51:56 <foreverska> What kind?
May 22 00:52:25 <raspberrypifan> 3.B
May 22 00:52:36 <foreverska> 3.B?  Thats a funny sounding animal
May 22 00:52:51 <raspberrypifan> i figured its 3 times B
May 22 00:52:52 <H-H-H> good job there was no typo there lol
May 22 00:52:58 <H-H-H> im getting a boneR
May 22 00:53:24 <raspberrypifan> r u
May 22 00:56:17 <foreverska> You can switch 3.3v by a transistor right?
May 22 00:56:44 <raspberrypifan> idk
May 22 00:56:45 <raspberrypifan> whats that mean
May 22 01:29:28 <treeherder> thurgood it's got plenty of power
May 22 01:33:52 <treeherder> i think i accidentally formatted fdisked the emmc
May 22 01:34:11 <treeherder> can it fix itself
May 22 01:34:53 <thurgood> sure, but you need to be able to flash it
May 22 01:36:49 <treeherder> i have a debian image
May 22 01:36:55 <treeherder> that i've used to flash it before
May 22 01:36:59 <treeherder> everything was good
May 22 01:37:10 <treeherder> and then i was reformatting what i thouight was the microSD
May 22 01:37:24 <treeherder> and accidentally the rootfs
May 22 01:37:50 <treeherder> so i've falshed it like 3 or 4 times with different images since getting the board
May 22 01:38:10 <treeherder> but this time it's taken 3 hours ish and still not solid LEDs
May 22 01:40:27 <thurgood> with the same card?
May 22 01:40:41 <treeherder> yes
May 22 01:40:42 <thurgood> and contents
May 22 01:40:52 <treeherder> i reflashed the ccard for sanity
May 22 01:41:19 <foreverska> dumb question but did you remove power and reapply before trying to boot to the card?
May 22 01:41:25 <thurgood> is the sd card's first parition bootable and all that fun stuff?
May 22 01:41:27 <treeherder> i plugged a (very expensive) hdmi in and it's booting to the desktop that tells you local changes woill not be saved
May 22 01:42:00 <treeherder> if i don't have the microsd it doesn't boot at all
May 22 01:42:08 <thurgood> guess it is bootable then
May 22 01:42:19 <thurgood> :/
May 22 01:47:44 <treeherder> mmblk0 bad sector
May 22 01:51:10 <treeherder> lights just startrs flashing usr0 ->1 ->2 -> 3 two times rapidlywith a short pause between each set of two
May 22 01:51:19 <treeherder> and it does that for hours
May 22 01:53:34 <thurgood> do you happen to have an FTDI -> USB cable?
May 22 01:57:48 <treeherder> yes
May 22 02:10:41 <treeherder> what should i do with it
May 22 02:14:46 <thurgood> well, have you seen if you can fdisk the partitions back? or tried another flasher image

May 22 02:35:24 <treeherder> thurgood,  what should the partitions look like
May 22 02:36:35 <thurgood> dunno exactly, I've never had the problem you're having
May 22 02:37:12 <thurgood> you can look at the images you're trying to flash with and figure it out though
May 22 02:41:00 <thurgood> do you have  2GB, or 4GB eMMC ?
May 22 02:51:21 <thurgood> for instance my board has 100MB for partition 1, and 3765MB as partition 2
May 22 02:53:09 <nyt> treeherder: which image are you trying to flash?
May 22 02:53:25 <nyt> if its not the 5/14 debian image, go try that one
