Apr 04 03:01:11 <trelane> this is ESPECIALLY bad on embedded
Apr 04 03:01:16 <trelane> where it's making changes we aren't explicityl wanting
Apr 04 03:01:33 <veremit> yup
Apr 04 03:01:35 <trelane> because if it's rekilling wifi after it's explicitly started
Apr 04 03:01:39 <trelane> that's an unautorized change of state.
Apr 04 03:01:57 <trelane> that's how you get effluent flowing down the walls of cruise ships
Apr 04 03:02:28 <trelane> hey the system should reset and shut down all the flow control valves
Apr 04 03:02:33 <trelane> wait, why did all the toilets back up?
Apr 04 03:03:03 <veremit> yeah somehow I don't think our friend poettering cares about that .. its "intentional" ..
Apr 04 03:03:15 <trelane> no wonder people are taking contracts out on his life
Apr 04 03:03:20 <trelane> I've half a mind to collect on one
Apr 04 03:03:27 <veremit> pig headed moron .. just like some presidential candidates *snicker*
Apr 04 03:03:34 <trelane> some?
Apr 04 03:03:35 <trelane> all.
Apr 04 03:03:57 <veremit> I was erring on the side of caution .. lol .. all politicians are corrupt
Apr 04 03:04:05 <veremit> its in the job desc.
Apr 04 03:04:35 <veremit> something to do with being born into a wealthy family
Apr 04 03:04:43 <trelane> why can't I at least manually save state for wifi?
Apr 04 03:04:47 <veremit> or just being a money-grabbing git.
Apr 04 03:04:54 <trelane> Ic an't even figure out what to tell systemd-rfkill to save
Apr 04 03:05:13 <snowstaff> =)
Apr 04 03:05:14 <veremit> uhm .. I think there is a *way* .. I just don't know what it is ..
Apr 04 03:06:12 <trelane> I don't care if the state ever changes again
Apr 04 03:06:21 <trelane> since systemd-rfkill@.service isn't SAVING state
Apr 04 03:06:31 <trelane> I just need it to get it to load an enabled state
Apr 04 03:09:07 <trelane> I can't even blacklist rfkill
Apr 04 03:09:36 <veremit> lol
Apr 04 03:10:59 * trelane idly considers what one of his 500gr 458 SOCOM rounds would do to Poettering's face.
Apr 04 03:13:14 <trelane> right now the whole BBB platform is pretty useless if it can't sustain a wifi connection.
Apr 04 03:14:33 <veremit> trelane: try https://groups.google.com/forum/#!msg/beagleboard/4FXi2-zq7Zw/NmeZfTCRBgAJ /
Apr 04 03:15:17 <veremit> yea I recall something about networkd
Apr 04 03:15:33 <veremit> ugh leave me with openrc and [e]udev
Apr 04 03:15:48 <veremit> even sysvinit is tolerable
Apr 04 03:16:25 <trelane> veremit, yeah I've read that, it doesn't work here
Apr 04 03:16:37 <trelane> I'd considered jumping in but the thread is 4 months old
Apr 04 03:17:59 <veremit> http://madscientistlabs.blogspot.co.uk/2015/01/wifi-on-beaglebone-black-with-systemd.html ?
Apr 04 03:18:05 <veremit> soooo  many stupid gotchas
Apr 04 03:27:43 <veremit> trelane: if you can hang around and not tear ya hair out too much, rcn-ee is usually here during the week to probe .. :D
Apr 04 08:08:43 <Designer> Hi, I'm looking for the frequency range of the SPI clock of the beaglebone black. Does anyone know what this frequency range is or where I can find it?
Apr 04 08:11:42 <snowstaff> Designer, i guess u can find it in TRM, chapter 24.2
Apr 04 08:16:22 <snowstaff> Guys, why if i enable the IEP counter, my GPIO  stop receive bits?
Apr 04 08:20:10 <snowstaff> Switching from iep_clk to ocp_clk is only supported in software. Switching back from ocp_clk to iep_clk is only supported through a hardware reset of the PRU-ICSS...dumb
Apr 04 08:21:25 <snowstaff> It is not
Apr 04 09:35:11 <elhe1> Does anyone know if there is a GPIO C/C++ library for the BBB similar like the python rpi.gpio library for raspberry pi
Apr 04 09:44:25 <LetoThe2nd> elhe1: libsoc
Apr 04 09:44:45 <elhe1> thanks
Apr 04 09:58:56 <alfatau> hello all. I've a bootstrap problem to debug, that happens very rarely. Is there some way to increase the verbosity of bootstrap logs (e.g. on /var/log/message or /var/log/syslog)?
Apr 04 11:39:06 <Rotti> hi!
Apr 04 11:43:19 <dirkk> hey
Apr 04 11:56:47 <izurd16> hi there channel
Apr 04 12:02:10 <izurd16> I've got a BBB it came with angstrom distro I've flashed eMMC the other day with jessie but I only have or appears the console. Are there any options or ways to installed it with a desktop environment just in eMMc
Apr 04 12:04:31 <izurd16> I have flashed with BBB-eMMC-flasher-debian-8.3-console-armhf-2016-03-11-2gb.img but only a console appears
Apr 04 12:06:20 <izurd16> are there a flasher image with desktop environment?
Apr 04 12:07:57 <alexhiam> izurd16: https://debian.beagleboard.org/images/
Apr 04 12:08:01 <LetoThe2nd> izurd16: those who don't have the "console" word in the name, but maybe lxde :-)
Apr 04 12:08:11 <alexhiam> you probably want https://debian.beagleboard.org/images/bone-debian-8.3-lxqt-4gb-armhf-2016-01-24-4gb.img.xz
Apr 04 12:08:41 <alexhiam> jessie + lxqt
Apr 04 12:11:55 <izurd16> alexhiam: but that image can't store in eMMc or what?
Apr 04 12:13:10 <alexhiam> izurd16: any debian image can be flashed to the emmc now - you have to first boot off the sd card and enable the flasher script...
Apr 04 12:13:26 <alexhiam> see Robert's last post here: https://groups.google.com/forum/#!topic/beagleboard/a5K7wqjLsA8
Apr 04 12:14:17 <alexhiam> then do the same flashing process
Apr 04 12:14:34 <izurd16> alexhiam: mine is Rev A5C
Apr 04 12:15:50 <alexhiam> izurd16: ohh, so 2GB eMMC then... I don't think there's a non-console image that will fit
Apr 04 12:16:13 <alexhiam> you'd have to start with the console image and install a lightweight desktop yourself
Apr 04 12:16:40 <alexhiam> or just use that image and boot from the sd card
Apr 04 12:18:19 <izurd16> alexhiam: will fit in 2GBeMMc lightweight desktop lxde for instance
Apr 04 12:19:38 <alexhiam> izurd16: not sure, you'd have to try it and see. Any reason you don't want to boot off the sd card?
Apr 04 12:22:19 <izurd16> alexhiam: new generation bbb what's size of eMMc has? the reason keep the sd card slot for store extra data
Apr 04 12:22:30 <alexhiam> 4GB
Apr 04 12:22:57 <izurd16> right... it doubles
Apr 04 12:24:08 <izurd16> any suggestions for my bbb 2gb emmc memory for what purpose for instance
Apr 04 12:25:10 <izurd16> alexhiam: could make a drone?
Apr 04 12:26:51 <alexhiam> I always just boot off sd cards. If you run the grow_partition.sh script you'll have lots of space: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Expanding_File_System_Partition_On_A_microSD
Apr 04 12:31:02 <izurd16> alexhiam: boot it right now. it booted from sd card debian jessie lxqt desktop but if I boot without sd card it's the console debian jessie without desktop
Apr 04 12:33:19 <izurd16> alexhiam: I don't know how to do that with *.sh script you mentioned
Apr 04 12:33:52 <alexhiam> which? grow_partition.sh?
Apr 04 12:34:21 <izurd16> that's right, alexhiam
Apr 04 12:34:50 <alexhiam> just run those commands from that link
Apr 04 12:36:09 <izurd16> alexhiam: from http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Expanding_File_System_Partition_On_A_microSD
Apr 04 12:37:27 <alexhiam> yeah
Apr 04 12:37:36 <izurd16> alexhiam: see what's happen... one minute please
Apr 04 12:37:44 <alexhiam> it just grows the partition to fill the sd card
Apr 04 12:38:57 <izurd16> but right now I've booted from sdcard
Apr 04 12:39:18 <izurd16> alexhiam: doest't matter?
Apr 04 12:39:28 <alexhiam> yeah, you want to boot from the sd card, run those commands then reboot
Apr 04 12:39:47 <izurd16> all right
Apr 04 12:45:42 <izurd16> done it alexhiam
Apr 04 12:47:22 <izurd16> alexhiam: what about if I boot it without sdcard
Apr 04 12:48:20 <alexhiam> it'll just boot whatever's on the emmc
Apr 04 12:50:29 <izurd16> alexhiam: so what image do you suggest for emmc the old ones
Apr 04 12:51:15 <izurd16> alexhiam: sorry to repeat the same question :-(
Apr 04 12:54:26 <alexhiam> izurd16: idk, I don't really use the emmc, but I'd sa the console image if it needs to fit in 2GB
Apr 04 12:57:22 <izurd16> alexhiam: what I really got with this BBB rev A5C?
Apr 04 12:59:30 <alexhiam> what do you mean? If 2GB isn't enough just boot from the sd card. for many applications 2GB with a console image is fine
Apr 04 13:00:07 <izurd16> alexhiam: can I flash the emmc as much as I what?
Apr 04 13:01:02 <izurd16> alexhiam: what i can do with this BBB?
Apr 04 13:02:06 <alexhiam> it'll wear out eventually, but you can probably flash it around 10 thousands times ;)
Apr 04 13:03:23 <alexhiam> whatever you want... there's plenty of projects out there, check out http://beagleboard.org/project/ and https://hackaday.io/list/3562-beaglebone-projects
Apr 04 13:04:51 <izurd16> alexhiam: even with my BBB?
Apr 04 13:05:09 <alexhiam> you mean because it's got a 2GB eMMC??
Apr 04 13:05:22 <Spidler_> I've got plenty of the 2GB ones, you'll be fine :)
Apr 04 13:05:55 <izurd16> alexhiam: teah that's right
Apr 04 13:06:00 <Spidler> The default images are a tad bloated, even the console one, so there's a fair bit you can cut to clean out things.
Apr 04 13:06:38 <izurd16> alexhiam: teah = yeah sorry
Apr 04 13:06:39 <Spidler> And if you feel _really_ creative you can build a Read-only squashfs image and have the whole system + webserver in < 200 megs of flash, giving you 1.8 Gigs of free space to play around with.
Apr 04 13:07:30 <alexhiam> and like I said, if it's not enough space you can boot from the sd card. If you have a 16GB sd card and you run that grow_partition.sh script then you'll have 16GB to play with
Apr 04 13:07:37 <alexhiam> and you can keep all the bloat :P
Apr 04 13:07:42 <Spidler> Heh. that too!
Apr 04 13:08:03 <Spidler> alexhiam: I've got one here where the SD card slot is faulty, that one is trickier to reflash :)
Apr 04 13:08:13 <Spidler> ( I've got a lot of beagles. )
Apr 04 13:08:26 <alexhiam> you use the usb flasher for that?
Apr 04 13:08:46 <Spidler> I put it in a cabinet and pretend it doesn't exist
Apr 04 13:09:01 <izurd16> is it faster than a Pentium 4- 500 mb ram?
Apr 04 13:09:23 <Spidler> Faster per watt? Guaranteed.
Apr 04 13:09:46 <Spidler> Faster otherwise? Depends on the operations.  the P4 had a very long pipeline that did some interesting things to get that performance
Apr 04 13:09:58 <Spidler> P4 clocked up at ~3 GHz speed which is quite impressive
Apr 04 13:10:13 <Spidler> ( some of them clocked up past 4GHz, which was just excellent space heaters )
Apr 04 13:10:48 <izurd16> I got a laptop pentium 4 running wheezy as a webserver
Apr 04 13:10:54 <Spidler> ssh dist
Apr 04 13:10:57 <Spidler> Sorry, wrong window.
Apr 04 13:11:36 <izurd16> time for lunch bbl
Apr 04 14:41:34 <izurd16> alexhiam: are you there'
Apr 04 15:01:14 <dirkk> izurd16: Did you flash your emmc ?
Apr 04 15:17:30 <alfatau> hello all. I would like to print some messages on serial console during boot. I've a systemd service which executes a script where i print some messages using systemd-cat. however it appears only in log files and not on serial. I need these logs when filesystem mount fails. Actually i'm saving messages through serial to file. can you help me?
Apr 04 15:25:49 <raffo>  hello, Is it possible to set the CPU frequency of the bbx15 board at boot? I would like to start the boot sequence at the lowest cpu frequency possible.
Apr 04 15:37:03 <tbr> alfatau: and where are you writing those messages to with this systemd-cat thing?
Apr 04 15:37:36 <tbr> alfatau: you could pastebin or gist your script so that it can be inspected, else it's just random guessing
Apr 04 15:42:55 <izurd16> hi there channel
Apr 04 15:43:16 <alfatau> tbr: ok, this is the service called "lynda9project.service"
Apr 04 15:43:35 <alfatau> tbr:http://pastebin.com/MJKPtbYm
Apr 04 15:43:54 <izurd16> running jessie on my computer how can I recognize BBB by usb
Apr 04 15:44:15 <tbr> alfatau: content of /home/lynda9/run_project.sh is?
Apr 04 15:44:22 <alfatau> tbr: this instead is the script run_project.sh
Apr 04 15:46:41 <alfatau> tbr: http://pastebin.com/w9AamGjk
Apr 04 15:48:14 <izurd16> dirkk: yes
Apr 04 15:48:30 <alfatau> tbr: i want to see these messages not only on /var/log/syslog but also on serial console, in order to redirect the whole output onto a text file that contains logs even when boot fails and fs is not mounted
Apr 04 15:48:38 <izurd16> sorry for me delay dirkk
Apr 04 15:48:54 <izurd16> dirkk: are you there?
Apr 04 15:49:40 <tbr> alfatau: I'd redirect STDERR and STDOUT
Apr 04 15:51:05 <alfatau> tbr: ok. and where would you redirect them?
Apr 04 15:51:37 <alfatau> tbr: actually I can see only the message corresponding to service description
Apr 04 15:51:59 <tbr> to /dev/console?
Apr 04 15:52:41 <tbr> there might be a cleaner way, but I'm not versed in systemd
Apr 04 15:52:55 <tbr> as this is just brute force
Apr 04 15:55:02 <alfatau> tbr: ok, thank you
Apr 04 15:56:31 <tbr> alfatau: by the looks of it, it might be enough to increase the log level
Apr 04 15:56:38 <tbr> you are using 'info'
Apr 04 15:57:26 <alfatau> tbr: ok, and where can i increase the log level?
Apr 04 15:57:39 <alfatau> tbr: do you mean in my script?
Apr 04 15:58:00 <tbr> man systemd-cat
Apr 04 16:00:04 <izurd16> second step it's not on green what should I do?
Apr 04 16:00:56 <izurd16> which the driver
Apr 04 16:01:12 <izurd16> I mean which is the driver
Apr 04 16:04:57 <izurd16> how do I install the driver in debian linux jessie
Apr 04 16:08:30 <tbr> izurd16: are you running jessie on your laptop/desktop PC?
Apr 04 16:29:50 <izurd16> tbr: yeah
Apr 04 16:30:26 <izurd16> tbr: are you there?
Apr 04 16:30:28 <tbr> then you don't need to install any special drivers to work with a BBB
Apr 04 16:30:34 <tbr> impatient, aren't we?
Apr 04 16:30:47 <izurd16> you right
Apr 04 16:31:16 <izurd16> second step it's not on green though
Apr 04 16:32:49 <izurd16> tbr: first step ok it's in green... then second how do I do that?
Apr 04 16:33:07 <tbr> what step? what's not green?
Apr 04 16:33:41 <izurd16> getting start
Apr 04 16:33:51 <izurd16> getting started
Apr 04 16:35:00 <izurd16> geeting started  second step, tbr
Apr 04 16:35:20 <izurd16> tbr, how I activate it
Apr 04 16:36:06 <izurd16> how do I activate it, you know what I mean tbr?
Apr 04 16:36:18 <tbr> no, what _is_ the second step?
Apr 04 16:37:12 <izurd16> tbr, install driver that's what it says
Apr 04 16:37:38 <tbr> you do not need to
Apr 04 16:37:42 <tbr> what's step three?
Apr 04 16:38:42 <izurd16> browse to web server on board
Apr 04 16:38:57 <tbr> then try that
Apr 04 16:41:05 <izurd16> I think if you don't pass 2 step can't go to third
Apr 04 16:41:50 <izurd16> I don't know how to browse to web server on board
Apr 04 16:44:43 <izurd16> http://beagleboard.org/getting-started tbr
Apr 04 16:49:19 <izurd16> tbr, can you assist please
Apr 04 16:50:38 <tbr> izurd16: http://192.168.7.2 does that link work for you?
Apr 04 16:51:32 <izurd16> tbr, no at all
Apr 04 16:52:11 <tbr> izurd16: you might want to check your network settings
Apr 04 16:52:59 <izurd16> tbr, got ethernet cable connected to BBB
Apr 04 16:54:11 <izurd16> tbr, how then?
Apr 04 16:54:45 <tbr> izurd16: ethernet or USB?
Apr 04 16:56:27 <Rickta59> does it show up as a usb drive? ( the bbb )
Apr 04 16:57:31 <izurd16> tbr, BBB is connected by usb to the laptop at the sane time got another ethernet cable plugged in BBB
Apr 04 16:58:25 <tbr> izurd16: can you please pastebin the output of "ip addr" on your PC?
Apr 04 16:58:47 <tbr> do NOT paste to the channel. use something like pastebin.mozilla.org or pastebin.com
Apr 04 17:00:40 <izurd16> Rickta59: I guess it doesn't show up as a usb drive I not sure I've plugged and another volume appears as BEAGLEBONE
Apr 04 17:04:24 <izurd16> http://pastebin.com/A6S551YX tbr
Apr 04 17:05:41 <izurd16> tbr, it's all right?
Apr 04 17:07:24 <tbr> by the looks of it 'eth1' is the USB network interface toward the BBB
Apr 04 17:07:49 <tbr> you just need to tell your computer to bring up the interface
Apr 04 17:08:28 <tbr> or if you'd prefer to talk to it over ethernet, then you'd need to look up its IP address that it got assigned by your router
Apr 04 17:08:49 <izurd16> is it because ethernet cable is plugged or what?
Apr 04 17:09:16 <izurd16> on BBB?
Apr 04 17:10:02 <tbr> is what?
Apr 04 17:11:01 <izurd16> I mean I have unplugged the ethernet cable from BBB
Apr 04 17:12:05 <tbr> and what do you expect to happen after unplugging?
Apr 04 17:13:22 <izurd16> you tell me should I plug ethernet cable to BBB or not
Apr 04 17:14:02 <izurd16> which is better or is it possible both ways?
Apr 04 17:14:28 <izurd16> right now is unplugged
Apr 04 17:15:33 <izurd16> how do I bring up the interface without plugging the ethernet cable
Apr 04 17:18:27 <tbr> I am talking about 'eth1' on your desktop running linux
Apr 04 17:19:01 <izurd16> at the same time is sd-card on it when plugged through usb
Apr 04 17:19:55 <izurd16> eth1 is BBB ok, so?
Apr 04 17:20:09 <tbr> eth1 is the USB network connection to your BBB
Apr 04 17:20:53 <izurd16> how do I bring it up then
Apr 04 17:21:45 <tbr> are you using network-manager or systemd networkd?
Apr 04 17:22:11 <izurd16> really don't know tbr
Apr 04 17:22:58 <tbr> you might want to reserve some time to learn about the desktop linux you are running...
Apr 04 17:23:13 <tbr> anyway, open network settings, look for eth1?
Apr 04 17:24:47 <izurd16> ip adrr command?
Apr 04 17:25:12 <izurd16> sorry ip addr command
Apr 04 17:25:21 <tbr> your desktop has a graphical user interface, doesn't it?
Apr 04 17:26:48 <izurd16> right turn it on then, right?
Apr 04 17:28:11 <tbr> yes...
Apr 04 17:29:07 <izurd16> tbr what's next....should I plug the ethernet cable to BBB
Apr 04 17:29:30 <tbr> the ethernet cable is irrelevant for now
Apr 04 17:29:42 <izurd16> all right
Apr 04 17:29:49 <tbr> did the second network interface get an IP address now?
Apr 04 17:29:53 <tbr> the UI should show you
Apr 04 17:30:26 <izurd16> UI user interface, right?
Apr 04 17:30:52 <tbr> yes, the network settings application that you should be using
Apr 04 17:31:14 <izurd16> nothing... only hardware address
Apr 04 17:34:22 <tbr> did you enable it?
Apr 04 17:35:09 <izurd16> yeah sure says on/off it's on
Apr 04 17:35:29 <izurd16> only hardware address
Apr 04 17:36:17 <tbr> try setting the IP to 192.168.7.1
Apr 04 17:37:00 <izurd16> how?
Apr 04 17:37:46 <izurd16> tried that ip on the firefox browser only not working
Apr 04 17:40:07 <izurd16> so?
Apr 04 17:40:59 <tbr> I am sorry, but you don't seem to understand how to operate your desktop. I can't help you.
Apr 04 17:43:48 <Guest37374> Hey y'all! Anyone here who knows about getting the Beaglebone to support a nonstandard resolution?
Apr 04 17:43:57 <izurd16> ipv4 tbr?
Apr 04 17:52:47 <izurd16> tbr, i'm on it but can apply cause more setting required
Apr 04 17:53:00 <izurd16> can't apply I mean
Apr 04 17:53:54 <izurd16> don't give it up please drive me

Apr 04 18:09:23 <izurd16> not activate yet to confirm
Apr 04 18:10:34 <izurd16> tbr, need something in dns
Apr 04 18:10:44 <tbr> no you don't
Apr 04 18:11:07 <izurd16> can't apply... gesssss
Apr 04 18:11:37 <izurd16> filling up the IPv4
Apr 04 18:12:04 <izurd16> tbr, in routes?
Apr 04 18:12:50 <tbr> no
Apr 04 18:14:13 <izurd16> why doesn't apply option activate, tbr
Apr 04 18:14:45 <izurd16> to confirm changes
Apr 04 18:15:54 <tbr> no idea
Apr 04 18:15:56 <izurd16> something is missing

Apr 04 18:37:22 <izurd16> hi there channel back again
Apr 04 18:38:35 <izurd16> tbr, it shows me the ip address in usb ethernet
Apr 04 18:39:00 <izurd16> tbr, after rebooting jessie
Apr 04 18:39:56 <tbr> well, then it should work, shouldn't it?
Apr 04 18:41:51 <izurd16> I put the ip you told me in the browser but nothing I have to plug the ethernet cable or not?
Apr 04 18:52:29 <izurd16> tbr, board connected at this IP http://192.168.7.2/bone101/Support/bone101/
Apr 04 18:53:23 <Nevyn|Work> Trying to get internet over USB?
Apr 04 18:54:37 <izurd16> <Nevyn|Work, to me
Apr 04 18:55:13 <Nevyn|Work> izurd16: Just trying to get contact from BBB to host, or from BBB to internet?
Apr 04 18:55:13 <izurd16> <Nevyn|Work,
Apr 04 18:56:21 <izurd16> <Nevyn|Work, so unplug the other connection then
Apr 04 18:56:43 <izurd16> <Nevyn|Work, so unplug the other connection then?
Apr 04 18:56:52 <Nevyn|Work> You can run everything over USB if you have it all set up. Is that what you are trying to do?
Apr 04 18:57:51 <izurd16> well yeah
Apr 04 18:58:07 <Nevyn|Work> Okay. Do you have SSH into the BBB working?
Apr 04 18:58:43 <izurd16> I don't know how can
Apr 04 18:59:01 <Nevyn|Work> http://ofitselfso.com/BeagleNotes/HowToConnectBeagleboneBlackToTheInternetViaUSB.php
Apr 04 21:19:37 <awesomo4000> Is there an implementation of JTAG for BBB PRUs that turns the BBB into a JTAG programmer?
Apr 04 21:50:09 <grrmp> Hi All
Apr 04 21:50:27 <epipe> hi
Apr 04 21:51:08 <grrmp> I've been loading up the onewire dtc to use a pin to read a DS18B20, but have struck some issues.  Anyone knowledgeable about this?
Apr 04 22:06:39 <veremit> grrmp: what issues?
Apr 04 22:08:00 <veremit> I've got a 18B20 on a couple of arduinos :)
Apr 04 22:30:53 <grrmp> veremit... I've got the device tree loaded, and it appears in slots, but the BBB does not detect any DS18B20's --I've tried 5, and two BBB's.
Apr 04 22:31:09 <grrmp> voltages across each pin are correct (around 3.3 V).
Apr 04 22:32:05 <veremit> what resistor you got the D pin?
Apr 04 22:32:18 <veremit> mine seem to be 47k ...
Apr 04 22:32:27 <veremit> but that's running on 5v
Apr 04 22:32:43 <veremit> oh wait 4k7 my bad ..
Apr 04 22:33:01 <veremit> been reading 5band resistors all day, and this is 4 lol
Apr 04 22:33:11 <grrmp> yes, 4K7...  just checking again
Apr 04 22:33:47 <grrmp> yep 4.7 Kohm
Apr 04 22:34:27 <veremit> d pin in the middle, looking at flat side, gnd on left, supply on R?
Apr 04 22:35:14 <grrmp> yes, that is what it appears.  The things get rather hot if you reverse them....
Apr 04 22:35:24 <veremit> I'm trying to think of how you address them in linux ..
Apr 04 22:35:29 <kremlin> kind of a reach, but what does the HWREG() macro do (in CCS libraries for the am335x)
Apr 04 22:35:30 <veremit> isn't there a bus?
Apr 04 22:35:55 <kremlin> i read it 'accesses' the reg, but does it just read it? or can you use it to write to the register too
Apr 04 22:35:57 <grrmp> yes, what you do is .... root@beaglebone:~# ls /sys/bus/w1/devices/w1_bus_master1 driver  power  subsystem  uevent  w1_master_add  w1_master_attempts  w1_master_max_slave_count  w1_master_name  w1_master_pointer  w1_master_pullup  w1_master_remove  w1_master_search  w1_master_slave_count  w1_master_slaves  w1_master_timeout
Apr 04 22:36:00 <kremlin> i can't really make sense of the definition
Apr 04 22:36:12 <grrmp> that is the output too -- but it is not finding the device
Apr 04 22:37:04 <grrmp> hi Kremlin -- I think you are used to working at a lower level than me.
Apr 04 22:37:12 <kremlin> maybe :)
Apr 04 22:37:32 <grrmp> I'm not used to delving that deep into the device.
Apr 04 22:39:50 <grrmp> any troubleshooting ideas veremit?
Apr 04 22:41:03 <veremit> grrmp: got an arduino?! lol uhm .. not really .. sorry :/
Apr 04 22:41:23 <veremit> I know its been done .. I'm certain I've seen tutorials online ..
Apr 04 22:41:58 <grrmp> Thanks anyway veremit. Yes there are some good tutorials round.  I've been using http://www.bonebrews.com/temperature-monitoring-with-the-ds18b20-on-a-beaglebone-black/#comment-9560
Apr 04 22:42:31 <grrmp> that has got the device tree loaded, and I've copied the circuit.  The only snag seems to be that the BBB does not detect the device!
Apr 04 22:44:30 <veremit> grrmp: yeah I was just looking at http://mkaczanowski.com/one-wire-ds1820-thermometer-with-beaglebone-black-libmicrohttpd/ :)
Apr 04 22:44:53 <veremit> seems the DT -could- be right .. but yet it might not .. if the device isnt being detected :/
Apr 04 22:45:23 <veremit> grrmp: what kernel version you on?
Apr 04 22:46:00 <grrmp> I saw that tute too. Strangely, that mkaczanowski circuit seems a bit wrong compared to the manual for the DS18B20 and the bonebrews circuit.
Apr 04 22:46:23 <grrmp> 3.8.13-bone70
Apr 04 22:47:52 <veremit> ah so you're at least on a "known good" kernel ..
Apr 04 22:48:05 <grrmp> So they say!
Apr 04 22:50:02 <veremit> grrmp: only other suggestion I have is to switch gpio pin .. but then that's me out :/
Apr 04 22:50:13 <veremit> shit .. and I must eat dinner lol
Apr 04 22:54:17 <grrmp> Thanks veremit .  I've tried that one already.  But I can give it another go.
Apr 04 22:54:27 <grrmp> Thanks for your help!
Apr 04 22:56:58 <veremit> good luck
Apr 04 23:43:17 <Ragnorok> The DS18B20 driver must be part of the distro then?  It should appear in kern.log when it loads, right?
Apr 04 23:43:50 <Ragnorok> Poo; grrmp be gone.
Apr 04 23:45:33 <veremit> Ragnorok: I think 1wire is
Apr 04 23:46:38 <Ragnorok> It looked to me like the devices weren't found.  I haven't looked at the source but I'd expect load / scan to be logged somewhere, perhaps providing more data.
Apr 04 23:46:40 <veremit> many buses are
Apr 04 23:47:50 <veremit> yea I dunno whether the DT implicitly loads the 1w driver ..
Apr 04 23:48:35 <veremit> all I do know is these things are far from straight-forward lol
Apr 04 23:48:40 <Ragnorok> Mmm.  Me either.  There it is.   Just tossing out an idea to a missing recipient.  (grin)
Apr 04 23:49:32 <veremit> well it goes to logs anyway :)
Apr 05 00:25:00 <nerdboy> anybody get latest machinekit image working?
Apr 05 00:25:36 <nerdboy> just froze up twice on first/second boot
