Mar 20 04:42:21 <aneeesh> hi?
Mar 20 10:34:07 <Guest25921> Hello. I've just begun using the beagle bine black. My college has a rev A5B board. The board does not boot up. All 3 LEDS light up when I power it on. I've flashed the latest debain image on my SD card. It behaves the same ay when booting from the emmc. My SD card is only 2 GB. Is that the issue?
Mar 20 10:37:13 <tbr> that might be an issue
Mar 20 14:22:59 <mistawright> hey guys i was doing an update on my beaglebone black after installing packages and it seems to be freezing during building the db for the man pages. how can i get around this. I reboot i run dpkg --configure -a and then it starts and eventually freezes
Mar 20 14:25:47 <mp88> i have a problem
Mar 20 14:26:01 <mp88> is there anybody helps me?
Mar 20 14:26:52 <woglinde> mp88 maybe
Mar 20 14:35:40 <ogra_> or not ...
Mar 20 14:38:13 <av500> "how do I stay connected to irc?"
Mar 20 14:42:56 <mistawright> lol
Mar 20 14:49:59 <vinu> hi I want to know if wake on lan is available in BBB
Mar 20 14:50:15 <vinu> If yes how do I use it??
Mar 20 14:52:32 <vinu> is wake on lan possible in BBB??
Mar 20 14:57:18 <woglinde> vinu ni
Mar 20 14:57:20 <woglinde> nope
Mar 20 14:57:34 <vinu> is there any way to get it done??
Mar 20 14:57:43 <vinu> somehow
Mar 20 14:57:46 <vinu> ??
Mar 20 14:59:35 <tbr> by using different hardware
Mar 20 15:01:33 <vinu> for example??
Mar 20 15:02:52 <smurray> vinu: http://bit.ly/1CBS0JZ
Mar 20 15:05:23 <adhorden> Afternoon. Currently playing with a BeagleBone black. I am using Ubuntu. How can I change the banner that is displayed on serial debug?
Mar 20 15:05:48 <adhorden> This would be one ttyO0
Mar 20 15:06:00 <tbr> I'd guess that's 'motd'
Mar 20 15:08:35 <adhorden> @tbr good point did not think of that.
Mar 20 15:09:05 <tbr> there might be also something before that, which is part of the logon prompt. I forget how to set that, might be a getty option
Mar 20 15:09:49 <adj> is /etc/issue also shown there?
Mar 20 15:09:51 <tbr> on ubuntu the getty is likely configured in /etc/inittab
Mar 20 15:10:48 <bwarff> etc/issue and etc/issue.net
Mar 20 15:10:57 <adhorden> Basically I get rcn-ee.net console Ubuntu Image 2015-02-19 displayed as soon as I open up a serial debug with minicom and trying to remove it.
Mar 20 15:11:05 <adhorden> Do not think its motd.
Mar 20 15:11:33 <tbr> sounds like 'issue'
Mar 20 15:11:56 <adhorden> /etc/issue looks like the one but looking at it is dynamically created as it has IP information.
Mar 20 15:14:09 <tbr> brute force: grep rcn-ee.net\ console /etc/* -R
Mar 20 15:16:39 <adhorden> Thanks :-) Never occurred to me grep through etc.
Mar 20 15:41:25 <adhorden> Do you know how /etc/issue gets the IP address information? I have changed the ip address to fit better with my local network the eth0 information is shown correctly but usb0 I also changed is showing the default of The IP Address for usb0 is: 192.168.7.2
Mar 20 15:44:26 <Amil_> Hi, Can someone help me to set a password to the BB Cloud 9 IDE. Is that possible? If anyone in the network with IPADDESS:3000 can see the code files for now. I searched on the internet as well. But couldnt find an effective solution. Thanks
Mar 20 15:57:33 <vvu> adhorden: it it hardcoded :) when the rootfs is created rcn puts there this default ip

Mar 20 16:22:15 <BeagleBug_> Is there any guide for installing real-time kernel patch for Ubuntu 14.04 on BeagleBoard xM?
Mar 20 16:25:07 <BeagleBug_> I was trying to look for info on rt-preempt. Can we use that on bbxM?
Mar 20 16:44:54 <Zock> Hello
Mar 20 16:45:21 <Zock> I have a question
Mar 20 16:46:17 <smurray> 42
Mar 20 16:46:26 <Zock> 42?
Mar 20 16:47:11 <smurray> it's the answer to life, the universe, and everything
Mar 20 16:47:19 <smurray> what's your question?
Mar 20 16:47:52 <Zock> I was wondering what languge to use to control a servo via TCP
Mar 20 16:48:03 <Zock> I just got the board
Mar 20 16:48:12 <Zock> beaglebone black
Mar 20 16:49:27 <smurray> that's doable with pretty much any language you're comfortable with using
Mar 20 16:49:48 <Zock> I know visual basic :D
Mar 20 16:50:00 <Zock> I don't think that works with the beaglebone
Mar 20 16:50:02 <smurray> yes, except that one
Mar 20 16:50:24 <Zock> what would you recomend?
Mar 20 16:50:58 <smurray> I've not used it, but the stock s/w image comes with bonescript, see http://beagleboard.org/Support/bone101
Mar 20 16:52:11 <smurray> there's also lots of documentation on using python if you google for it
Mar 20 16:52:45 <Zock> Thanks!
Mar 20 16:53:24 <smurray> Zock: no problem, good luck
Mar 20 17:11:39 <Amil_> Can someone help me to set a password to the BB Cloud 9 IDE. Is that possible? If anyone in the network with IPADDESS:3000 can see the code files for now. I searched on the internet as well. But couldnt find an effective solution. Thanks
Mar 20 17:26:36 <Zock> smurray: is there anything I need to do before it will work for me?
Mar 20 17:26:57 <Zock> Bonescript I mean
Mar 20 17:27:43 <Zock> I tried the onboard led program and it won't work for me
Mar 20 18:10:02 <smurray> Zock: sorry, I've never tried bonescript
Mar 20 18:10:19 <Zock> I got it figured out :D
Mar 20 18:14:05 <nerdboy> denix: is ti-staging best choice for bbb kernel?
Mar 20 18:14:33 * nerdboy building poky master with meta-ti and meta-qt5
Mar 20 18:14:59 <denix> nerdboy: depends on what you need
Mar 20 18:17:04 <denix> nerdboy: that has all the latest peripheral support from TI for 3.14, but for things like capes, you need some pieces backported, like what rcn-ee is doing...
Mar 20 18:17:55 <nerdboy> don't have any cape requirements for now, just video/egl/browser
Mar 20 18:18:18 <nerdboy> have also built rcn kernel with sgx stuff
Mar 20 18:18:37 <nerdboy> shoudl i go with that instead?
Mar 20 18:19:24 <nerdboy> can test with hand-tweaked rootfs but need a full oe build image eventually...
Mar 20 18:20:53 <nerdboy> qtbase/5.0.1 upstream tarball changed...
Mar 20 18:20:56 <nerdboy> yay
Mar 20 18:21:03 <denix> nerdboy: sgx should all be in meta-ti, not sure if rcn-ee has anything on top of that
Mar 20 18:21:37 <nerdboy> sgx is manual "extra" build/install on top of bb-kernel
Mar 20 18:21:41 <denix> btw, you probably want some newer qt5... :)
Mar 20 18:21:57 <nerdboy> yeah, i kinda thought that too...
Mar 20 18:22:02 <denix> why is it manual?
Mar 20 18:22:11 <nerdboy> martin's readme is er, minimal...
Mar 20 18:22:34 <nerdboy> it's manual in robert's wiki page
Mar 20 18:24:26 <nerdboy> okay, another qtbase error
Mar 20 18:25:02 <nerdboy> denix: is master funky/not current in meta-qt5?
Mar 20 18:25:39 <denix> using meta-qt5/master here
Mar 20 18:27:31 <nerdboy> and yours is newer than 5.0.1?
Mar 20 18:28:57 <nerdboy> crap
Mar 20 18:29:46 * nerdboy notes don't try this at home...  especially when delirious with andromeda virus...
Mar 20 18:30:27 <nerdboy> git remote show origin  =>  Fetch URL: git@github.com:prabindh/meta-qt5.git  wtf?
Mar 20 18:32:23 <nerdboy> probably help if i had cloned the right f*cking repo...
Mar 20 18:32:34 <denix> heh
Mar 20 18:33:09 <nerdboy> still a ton of TI LICENSE warnings...
Mar 20 18:34:00 <denix> nerdboy: is that from master?
Mar 20 18:35:26 <nerdboy> yup
Mar 20 18:35:30 <denix> btw, I'm surprised we are not being kicked out from here - this is an oe/yocto/ti haters channel... :)
Mar 20 18:36:02 <nerdboy> but it's the best way to build your own image for beaglebone...
Mar 20 18:36:52 <nerdboy> s/best/quick,easy/
Mar 20 18:38:12 <veremit> lol
Mar 20 18:56:13 <_av500_> denix: nonsense
Mar 20 18:56:20 <_av500_> we welcome hate for all things here
Mar 20 18:57:03 <denix> _av500_: the highest level of tolerance!
Mar 20 18:57:21 <veremit> ^5
Mar 20 18:57:54 <_av500_> denix: just dont mention rpi
Mar 20 18:59:16 * agmlego|skynet hisses
Mar 20 18:59:56 <nerdboy> hey, rsing tide floats all boats...
Mar 20 19:00:14 * nerdboy likes adafruit lady and all their stuff
Mar 20 19:00:15 <_av500_> RSSing?
Mar 20 19:00:19 <denix> _av500_: that's heresy!
Mar 20 19:00:33 <nerdboy> including their bugs...
Mar 20 19:04:08 <rcn-ee> denix, nerdby, es9 sgx modules should be apt-get able' sudo apt-get install ti-sgx-es8-modules-`uname -r`
Mar 20 19:04:14 <rcn-ee> the userspace still needs to be extracted..
Mar 20 19:05:26 <nerdboy> for which rootfs?
Mar 20 19:05:46 <rcn-ee> nerdboy, all (ubuntu/debian/etc..) as long as the kernel is from repos.rcn-ee.net
Mar 20 19:06:47 <nerdboy> testing with multiple kernels/rootfs right now
Mar 20 19:07:46 <nerdboy> need to boil it down to a nice build image tho...
Mar 20 19:07:46 <rcn-ee> the trick, build qt in eglfs mode, then just run my kernel with the ti es8 sgx modules and ti's sgx userspace bins
Mar 20 19:08:20 <nerdboy> thaton the wiki yet?
Mar 20 19:08:34 <nerdboy> s/thaton/that on/
Mar 20 19:09:06 <rcn-ee> nerdboy, for jessie, i'm trying to set that up by defaut: https://github.com/rcn-ee/repos/blob/master/qtbase-opensource-src/suite/jessie/debian/rules#L53
Mar 20 19:09:13 <rcn-ee> just hasn't finished a buidl yet..
Mar 20 19:09:51 <nerdboy> and does your sgx module build match latest TI stuff?  es8 I guess?
Mar 20 19:09:56 <denix> rcn-ee: that should also work with ti-staging kernel from meta-ti... do you have any other sgx fixes on top?
Mar 20 19:10:32 <rcn-ee> denix, i believe so... you guys imported all the sgx patches i had been using. ;)
Mar 20 19:11:34 <denix> rcn-ee: yeah, we initially had those patches externally in meta-ti layer, but then merged them directly into kernel. you don't have anything extra of your own?
Mar 20 19:15:30 <rcn-ee> denix, the delta is mostly cape dts stuff: https://github.com/beagleboard/linux/compare/90ead9ea0bd41087504953e9a74c9dc60ce3fdb7...ee2a2099346924329953321c9c80e88841b0ddd3
Mar 20 19:15:50 <rcn-ee> but suprised you guys haven ran into: https://github.com/beagleboard/linux/commit/c3d6d1e1d2eadca99f681e7ed992b2adf04ad4fe
Mar 20 19:15:56 <rcn-ee> pinged dan on that one, mismerge of stable..
Mar 20 19:17:15 <denix> rcn-ee: thanks!
Mar 20 19:17:25 <denix> huh, that's weird...
Mar 20 19:18:43 <rcn-ee> in the 3.14.x stable branch that change is this: https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/drivers/usb/musb/musb_cppi41.c?h=linux-3.14.y&id=a5d6bd2499fb860e7eaa537973fddcc9d8157491
Mar 20 19:19:13 <veremit> uhoh .. musb crap?
Mar 20 19:19:35 <rcn-ee> veremit, even worse, it's the dma engine behind the musb crap..
Mar 20 19:19:42 <veremit> lol
Mar 20 19:20:05 <veremit> did I hear right that there might be a SoC project to re-write that from scratch?!
Mar 20 19:20:06 <rcn-ee> (that engine is pretty broken on the bbw's es1 silcon)
Mar 20 19:20:27 <rcn-ee> they'd need a time machine first..
Mar 20 19:20:34 <veremit> ah
Mar 20 19:21:00 <veremit> pity .. with usb being such a universal standard now .. to have f*cked it up is a real downer
Mar 20 19:21:10 <rcn-ee> nokia spec'd it to transfer vcards... it wasn't suppost to do anything else. ;)
Mar 20 19:21:24 <veremit> nokia didn't spec 'usb' .. :P
Mar 20 19:21:29 <denix> that's an old IP from Mentor...
Mar 20 19:21:40 <denix> i.e. musb
Mar 20 19:21:55 <veremit> but yeah I understna the history of the ip/silicon/driver
Mar 20 19:21:55 <denix> new SOCs no longer use that
Mar 20 19:22:31 <veremit> we need a beagle-black V2 .. quad core ;)
Mar 20 19:22:41 <denix> x15
Mar 20 19:22:42 <veremit> oh wait .. jkr isn't here
Mar 20 19:22:48 <veremit> no .. at the $30 price point
Mar 20 19:22:56 <denix> maybe in few years...
Mar 20 19:23:28 <veremit> that is the single + I will give to the RPi project .. they've proved the commercial viability of a $20-30 'computer'
Mar 20 19:23:31 <denix> x15 has a beast of an SOC! can't be cheap... :(
Mar 20 19:23:39 <veremit> denix ; precisely
Mar 20 19:23:55 <rcn-ee> veremit, broadcom also dumped the soc's on them at no cost. ;)
Mar 20 19:24:19 <veremit> rcn-ee : that was my suspicion, but thanks for the confirmation
Mar 20 19:24:37 <veremit> I prefered to use the term 'was in bed with'
Mar 20 19:24:46 <rcn-ee> i know the intial few thousands, broadcom had extra waffers with nothing to do with them..
Mar 20 19:25:11 <veremit> lol and now they have to keep makin 'em .. well, they'll be $-in . so many millions been made now
Mar 20 19:25:17 <denix> suspicion? it's a known fact - original ARM11 socs were surplus from STB market that nobody would buy
Mar 20 19:25:31 <veremit> denix: I didn't get that memo :p
Mar 20 19:26:51 <veremit> hell .. even *I*'da found a use for a coupla-hundred :p
Mar 20 19:40:09 <mastiff> rcn-ee, I'm getting this error starting a qt5 app in eflrfs mode from console.  Any ideas what I'm missing?   libEGL warning: DRI2: xcb_connect failed
Mar 20 19:41:48 <rcn-ee> it's calling xcb and it's trying to use xorg..  we don't want it to do that in elgfs mode..  if you can figure that out i have a cookie for you.. ;)
Mar 20 19:43:32 <rcn-ee> did you call the applition with "-platform eglfs"?
Mar 20 19:44:15 <mastiff> I think I build taulabs gcs app with my linux-beaglebone-g++ mkspec file that specifies eglrfs as default platform
Mar 20 19:44:58 <mastiff> I'm doing this on two BBBs since it's so time consuming, maybe I forgot to use the mkspec on that BBB.
Mar 20 19:45:09 <mastiff> I'll double check that
Mar 20 19:45:39 <mastiff> also will try running it with the command line -platform eglfs
Mar 20 19:55:20 <mastiff> same error if I use -platform eglfs
Mar 20 19:56:24 <mastiff> I forgot to use the linux-beaglebone-g++ mkspec when I built taulabs gcs, so hopefully that solves the issue
Mar 20 21:05:53 <veremit> rcn-ee .. any idea when jessie will be officially released?
Mar 20 21:07:29 <GenTooMan> <veremit> free advertising. Also one of the RPi board members is an exec at broadcom.
Mar 20 21:07:54 <rcn-ee> probally april: https://udd.debian.org/cgi-bin/rcblog.cgi
Mar 20 21:07:59 <veremit> GenTooMan : yes I knew this
Mar 20 21:08:15 <veremit> cheers, rcn
Mar 20 21:10:40 <veremit> ouch. Just noticed this debian box has a newer kernel than my normal gentoo install :(
Mar 20 21:10:57 <veremit> on the plus side .. sfdisk partitions my 8gb cards on this system ... :D
Mar 20 21:11:28 <veremit> only issue .. my dev files are on the gentoo system at work .. not here :/
Mar 20 21:11:45 <veremit> guess I'll have to sftp the critical ones and re-locate :\ lol

Mar 20 23:39:52 <newsham> whats the preferred way to boot an elf image on bbone baclk?  it has uboot but it doesnt support the bootelf cmd.  so far I've just been making a binary of the text region with objcopy, and then using "dhcp" and "go" to load and run it
Mar 20 23:40:04 <newsham> but is there  a more direct way to directly run an elf that is preferred?
Mar 21 00:34:52 <luciano> hi, i need help , can I use a beaglebone kernel with archlinux-arm rootfs ?
Mar 21 00:35:12 <veremit> yes
Mar 21 00:35:24 <veremit> or gentoo
Mar 21 00:35:27 <veremit> whatever you like
Mar 21 00:35:36 <luciano> veremit, thanks!
Mar 21 00:39:35 <clvrmnky> luciano: I'm running it right now
Mar 21 00:40:21 <clvrmnky> Almost all the distros mentioned on the elinux BB wiki are pretty solid and totally fun
Mar 21 00:40:48 <clvrmnky> Debian and Arch are battling it out to see who gets the eMMC
Mar 21 00:48:15 <Jake_> Hey fellow beagle enthusiasts! I'm fairly new to using a microcomputer with an OS, previous experience only includes programming mcu's like the msp430, tivaC, etc. I'm using a BBB in my final undergraduate project design and had a question regarding the power pins on P9. I'm trying to power a GPS cape which I designed using the MTK 3339 chipset, however the VDD_3V3 pin headers are not supplying voltage to the pcb (I checked using a vo
Mar 21 00:49:03 <veremit> clvrmnky .. would be interesting to see an arch script/image .. any idea who's working on it? or is it still in RN's domain!?
Mar 21 00:49:33 <Jake_> I'm powering the BBB through the 5V barrel jack and can boot into either Ubuntu or Android fyi
Mar 21 00:51:09 <clvrmnky> Well, the Arch Linux folks are at http://archlinuxarm.org/
Mar 21 00:51:36 <clvrmnky> They have root/boot images there, packages from their extensive PKGBUILDs
Mar 21 00:51:39 <clvrmnky> So that's nice.
Mar 21 00:52:17 <clvrmnky> It is a separate project from Arch Linux (which is x86/64 specific) and the Beagle folks.)
Mar 21 00:53:39 <clvrmnky> I'm leaning toward arch because one command and I'm up to date. For the thing I'm doing a rolling release is best.
Mar 21 00:54:04 <clvrmnky> But the Debian port is totally solid, too.
Mar 21 00:54:34 <veremit> yeah I like gentoo .. but don't fancy compiling everything on the arm all the damn time.... lol
Mar 21 00:54:51 <veremit> hence I'll probably stick to debian, particularly after the switch to jessie
Mar 21 00:55:05 <veremit> I've been interested in trying out arch though
Mar 21 00:55:07 <clvrmnky> Is that when the systemd stuff is done, too?
Mar 21 00:55:25 <veremit> rn's got systemd in his wheezy images...
Mar 21 00:55:32 <clvrmnky> Ah, ok.
Mar 21 00:55:50 <veremit> I personally avoid the systemd though if I can help it .. but i don't see me re-configuring for openRC lol
Mar 21 00:56:10 <clvrmnky> I'm a SysV/BSD person, so I wanted official systemd if at all just to swallow the whole pill at once.
Mar 21 00:56:21 <clvrmnky> Arch is all systemd.
Mar 21 00:57:15 <veremit> its fine if it works .. but I think it has its .. erm .. issues lol
Mar 21 00:57:37 <clvrmnky> It has been a learning experience. Personally, I'd rather if this particular system was more init/conf file based, but I need that sweet Linux community support. So here I am.
Mar 21 00:58:13 <clvrmnky> Basically, if pfsense was on the ARM, I'd probably be using it :)
Mar 21 00:58:56 <clvrmnky> I'm ignorant of "rn". Is that a person or a org?
Mar 21 00:59:40 <veremit> eewiki.net .. robert nelson .. done a LOT of work with embedded arm systems
Mar 21 00:59:53 * clvrmnky nods
Mar 21 01:01:39 <clvrmnky> More on topic, I've got some embedded experience, just not on the ARM or with prog pins so much. I'm considering actually using the GPIO capabilites on my otherwise boring project. Should I just bit-bang in the Linux manner, or is wiringx recommended.
Mar 21 01:05:32 <veremit> high speed gpio you probably want to involve the PRU's or something
Mar 21 01:05:36 <veremit> I've never used io on the beagle
Mar 21 01:05:51 <veremit> using an arduino for real-world integration lol
Mar 21 01:09:19 <clvrmnky> I'm thinking of a blinky light thing.
Mar 21 01:09:32 <clvrmnky> It's an edge box, so big red light when something needs attention
Mar 21 01:09:48 <veremit> yeah you can use /sys nodes I think for low-speed stuff
Mar 21 01:09:50 <clvrmnky> Dancing cylon lights when someone ectually reads my blog.
Mar 21 01:10:17 * clvrmnky puts a pin in /sys, that mysterious of linux inventions
Mar 21 01:10:21 <nerdboy> there is gpio python interface
Mar 21 01:10:54 <nerdboy> kernel modules for various sensors, etc
Mar 21 01:10:57 <clvrmnky> nerdboy: I saw that. Is it too noob to ask how python and wiring[x] fit together?
Mar 21 01:11:18 <clvrmnky> i.e., WTF is wiringX? The web site is opaque to me.
Mar 21 01:11:29 <veremit> not sure I'd wory about wiring(x0
Mar 21 01:11:36 <veremit> isn't that basedon wiringPi or somesuch
Mar 21 01:11:39 <clvrmnky> That's what I like to hear.
Mar 21 01:11:40 * nerdboy has heard of wiring_py
Mar 21 01:12:17 <nerdboy> i was thinking bbb,gpio or even adafruit wrapper
Mar 21 01:12:43 <clvrmnky> I'm trying to get a handle on how to start. Like, I grok rendering a C-like language into a chunk of event driven loop code for a modern uprocessor.
Mar 21 01:13:20 <clvrmnky> But doing this as a service within Linux is foreign to me.
Mar 21 01:13:47 <nerdboy> with the sensor stuff i think i ended up reading in a loop
Mar 21 01:13:57 <clvrmnky> My previous projects I've owned the processor, or had multiple processes task switching. Standard embedded stuff.
Mar 21 01:14:11 <nerdboy> web service uses same interface i think
Mar 21 01:14:27 <clvrmnky> ok, so a service with a busy wait or nice polling loop.
Mar 21 01:14:51 <clvrmnky> nice == let's try not to soak up all the CPU
Mar 21 01:15:09 <nerdboy> take a look at adafruit gpio python stuff
Mar 21 01:15:42 <nerdboy> think it's a cython module backend anyway
Mar 21 01:16:22 <clvrmnky> So, let me spitball a bit. You get a port using some Linux API, and do some stuff to it to make it an input, output, or whatever. Then you open that port and do unnatural things to it. Then, your hardware responds, as long as it is designed within spec.
Mar 21 01:16:22 <nerdboy> https://github.com/adafruit/adafruit-beaglebone-io-python
Mar 21 01:16:29 <clvrmnky> Is that about right?
Mar 21 01:16:32 <clvrmnky> nerdboy: yes,
Mar 21 01:16:44 <clvrmnky> I need to study adafruit links more.  Boomarked.
Mar 21 01:17:07 <nerdboy> that's about right for i2c devices
Mar 21 01:17:08 <clvrmnky> Bookmarked, even.
Mar 21 01:17:40 <nerdboy> leave pins in clean state after you do unnatural things...
Mar 21 01:17:49 <clvrmnky> Of course. But good point.
Mar 21 01:18:17 <nerdboy> some devices are not compliant and have unclean protocols
Mar 21 01:18:37 <clvrmnky> Also not suprising. Hardware is bane of software's existence.
Mar 21 01:18:46 <GenTooMan> I liked Boomarked myself explosive :D
Mar 21 01:18:53 <nerdboy> bitbang is last resort, but maybe the most fun...  for some people at least...
Mar 21 01:19:30 * nerdboy thinks there is generic gpio kernel module even
Mar 21 01:19:35 <clvrmnky> bitbang is great to prototype, but then you end up shipping.
Mar 21 01:19:44 <nerdboy> in latest kernels anyway
Mar 21 01:20:00 <clvrmnky> I'll look for my distro
Mar 21 01:20:23 <clvrmnky> This is good stuff. I'm actually taking notes. Well, saving this entire conversaiton to a log. Same thing.
Mar 21 01:21:28 <nerdboy> CONFIG_GPIO_OMAP and CONFIG_LEDS_GPIO
Mar 21 01:21:52 * clvrmnky looks
Mar 21 01:22:02 <nerdboy> i2c and spi too, so make sure you have those
Mar 21 01:22:12 <nerdboy> CONFIG_I2C_GPIO, etc
Mar 21 01:22:42 <nerdboy> and there is CONFIG_GPIO_GENERIC
Mar 21 01:23:19 <veremit> https://www.kernel.org/doc/Documentation/gpio/sysfs.txt
Mar 21 01:23:39 <nerdboy> you'll have to look at those and see what the interfaces look like
Mar 21 01:24:05 <clvrmnky> Good stuff. I have all of that in my stock kernel, either in the kernel or as modules.
Mar 21 01:24:15 <nerdboy> CONFIG_GPIO_SYSFS if nothing else
Mar 21 01:24:34 <clvrmnky> Much obliged. This is the sort of info I need to bootstrap myself to smarter questions.
Mar 21 01:24:51 <veremit> clvrmnky gotta start somewhere :)
Mar 21 01:25:01 <nerdboy> sensor module interfaces a tad better than i2c-gpio interface...  maybe...
Mar 21 01:25:33 <clvrmnky> I fully expect to make typical mistakes and rediscover the discovered. It's part of the process.
Mar 21 01:26:47 <nerdboy> if you really like arduino stuff better then kernel module is okay
Mar 21 01:28:03 <clvrmnky> "like"
Mar 21 01:28:19 <clvrmnky> Just more familiar.
Mar 21 01:28:52 <clvrmnky> I don't think of Linux as an embedded platform still. Typically, I own  everything.
Mar 21 01:29:18 <clvrmnky> Like, you fdo your own memory checksums to make sure cosmic rays haven't borked your runtime.
Mar 21 01:29:36 <nerdboy> https://github.com/adafruit/Adafruit_Python_GPIO  <=  this is not bad example of using the bbb.gpio backend
Mar 21 01:30:11 <clvrmnky> I think I'm 3 clicks into that one.
Mar 21 01:30:59 <nerdboy> previous url is backend
Mar 21 01:31:11 <clvrmnky> Well, that's a start. Seems a shame not to use the expansion ports for something, anyway.
Mar 21 01:31:39 <veremit> true
Mar 21 01:31:54 <veremit> I need to get a header on some veroboard :D
Mar 21 01:32:04 <ds2> sigh.... RC servos are not a standard size
Mar 21 01:32:13 <veremit> maybe tack on an RTC module and some stuff
Mar 21 01:32:19 <nerdboy> the python interfaces use i2c/spi kernel modules
Mar 21 01:32:21 <veremit> ds2: is ANYTHING a standard Anything?!
Mar 21 01:32:49 <ds2> veremit: you'd think the physical size is standard so people can put them into RC models easily
Mar 21 01:32:57 <ds2> and yes - fasteners are standard
Mar 21 01:33:17 <veremit> you'd think so .. and yet the americans still use imperial .. :P~
Mar 21 01:33:31 <ds2> nothing wrong with imperial
Mar 21 01:33:36 <ds2> it works. makes more sense
Mar 21 01:33:41 <veremit> just the rest of the world ditched it years ago .. :p
Mar 21 01:33:41 <honestly> lol
Mar 21 01:33:46 <GenTooMan> Well they are sort of semi standard you have micro mini standard and really big RC servos what are you doing with the servos?
Mar 21 01:33:59 <veremit> lol GenTooMan .. sounds as close as you get ;)
Mar 21 01:34:12 <ds2> GenTooMan: I got 2 that differs slightly in size... doing a robot platform
Mar 21 01:34:26 <ds2> it is close enough I can squeeze sheetmetal
Mar 21 01:34:40 <honestly> http://kaero.wz.cz/jokes/imperial-vs-si.png
Mar 21 01:35:19 <GenTooMan> <ds2> do you have the correct sweep angle for them? Their are several types you have 60 90 120 180 and 360. You probably won't want to use 360 as they tend to be a bit specialized.
Mar 21 01:35:40 <veremit> its the old story .. know ya sh1t .. ;) lol
Mar 21 01:35:44 <ds2> GenTooMan: continuos rotation
Mar 21 01:36:04 <veremit> ah servo-motor :p
Mar 21 01:36:09 <ds2> GenTooMan: I can drive it just fine from the BBB. it is the mechanicals. just got the sheetmetal worked out
Mar 21 01:36:20 <ds2> yes. too lazy to get H bridges
Mar 21 01:36:32 <GenTooMan> <ds2> that would be a 360. Most of them are mounted with wood and wood screws believe it or not.
Mar 21 01:36:35 <veremit> ds2: doesn't every first prototype need the file/angle-grinder/tin-snips??
Mar 21 01:36:55 <ds2> veremit: that is what CAD is suppose to do :P
Mar 21 01:37:02 <veremit> usually the third one actually works
Mar 21 01:37:07 <veremit> ds2: yeah. Right. lol :)
Mar 21 01:37:17 <ds2> GenTooMan: I see. I did a box frame to hold them but one is bigger then the other
Mar 21 01:37:43 <ds2> if I feel like it, I'll do another one. for now, sheetmetal bulges but holes things together
Mar 21 01:38:10 <GenTooMan> <veremit> The imperial standard works fine as long as people consistantly use it on a project. It's a pain when you are testing something and the morons spec 150F and all your devices use C (65.555555).
Mar 21 01:38:38 <ds2> people are focusing too much on conversions
Mar 21 01:38:38 <veremit> lol
Mar 21 01:38:51 <veremit> 100 inches very different to 100mm :D
Mar 21 01:39:03 <ds2> a foot is roughly the lenght of a foot. easy to explain and grasp
Mar 21 01:39:07 <GenTooMan> <ds2> really never guessed. 1m isn't a yard? :D
Mar 21 01:39:10 <ds2> a cm? wtf is that
Mar 21 01:39:34 <veremit> an oddity you get taught in schools -sigh- lol
Mar 21 01:39:53 <GenTooMan> what about a dm? or an hm I want a hm! :)
Mar 21 01:40:05 <veremit> I'll take a km :D
Mar 21 01:40:27 <ds2> what's a common thickness for paper? 2-3mils or 0.075mm? 75000um?
Mar 21 01:40:39 <ds2> it isn't scaled in a sane manner
Mar 21 01:40:43 <veremit> ds2: depends on the paper ;P
Mar 21 01:40:48 <veremit> 120gsm or ..
Mar 21 01:40:53 <veremit> oh wait .. you won't understand that ..
Mar 21 01:41:02 <veremit> :D
Mar 21 01:41:06 <ds2> that's like calling out 20lb paper
Mar 21 01:41:13 <GenTooMan> you could go by basis weight. :d
Mar 21 01:41:24 <ds2> it doesn't really tell you how thick it is w/o a lot of calculations
Mar 21 01:41:42 <ds2> if the goal is conversions, we need a powers of 2 measurement system. then just use a computer
Mar 21 01:41:51 <veremit> why do you need to know thickness of paper, unless you're designing a copier/printer?! lol
Mar 21 01:41:53 <clvrmnky> And 16 fingers
Mar 21 01:42:05 <ds2> cuz some of us use paper to shim stuff
Mar 21 01:42:21 <ds2> what do you do when you need to adjust thickness in 3-4mil range?
Mar 21 01:42:23 <veremit> old skool ;)
Mar 21 01:42:31 <veremit> surface grinder :D
Mar 21 01:42:32 <ds2> no, doing practical stuff
Mar 21 01:42:43 <veremit> think that does um.
Mar 21 01:42:54 <ds2> if you are working in 3-4mils, you don't need a surface grinder
Mar 21 01:43:16 <ds2> 3-4 millionth maybe
Mar 21 01:43:17 <GenTooMan> Actually it's very important to know paper thickness. For example if you are laminating 2 films with an adhesive layer at 200m per minute it is important to know what it's total thickness is for 250 sheets in a box.
Mar 21 01:43:18 <clvrmnky> There is a company that sells shims in packs of X, that offer exact thicknesses in expected tolerances.
Mar 21 01:44:03 <GenTooMan> I use to work in the tag and label industry and calculate basis weights in my head, I got better however :D
Mar 21 01:44:42 <ds2> it is extremely useful to know the typical thicknesses of common items
Mar 21 01:45:37 <GenTooMan> When you are working on a driver for a thermal printer knowing tolerances is important :D
Mar 21 01:46:00 <ds2> for added fun - both mks and cgs are metric
Mar 21 01:48:01 <GenTooMan> anyhow topic wise is their a cross compilor suite for Gentoo and the beagle boards?
Mar 21 01:48:31 <veremit> GenTooMan .. build your own
Mar 21 01:48:32 <ds2> what's wrong with the linaro, CS, etc toolchains?
Mar 21 01:48:38 <veremit> ctng
Mar 21 01:49:21 <ds2> that requires actually running a script!
Mar 21 01:49:38 <veremit> no .. thats the point .. CTng does it all for you :D
Mar 21 01:49:49 <GenTooMan> I use scripts all the time
Mar 21 01:49:55 <veremit> I can't remember where I saw how .. it was a 1-liner
Mar 21 01:49:55 <GenTooMan> I write em too
Mar 21 01:50:03 <veremit> scripts are good :)
Mar 21 01:50:11 <chainsawbike> GenTooMan, gentoo has crossdev - it will build a cross-compiling toolchain for you
Mar 21 01:50:35 <GenTooMan> <chainsawbike> thanks for the reminder ...
Mar 21 01:50:50 <ds2> you got to run ctng
Mar 21 01:52:18 * chainsawbike uses a chroot + qemu-user to build stuff for his BBB
Mar 21 01:54:01 <ds2> wonder how well does qemu-user work on the board itself
Mar 21 01:59:34 <GenTooMan> I just need to reinstall gentoo and use UEF for getting it to boot again. Sadly I borked the boot a while back the drive won't boot anymore (mutter)
Mar 21 02:00:37 <veremit> ew uefi
Mar 21 02:01:34 <nerdboy> uefi is a pain...
Mar 21 02:01:40 <GenTooMan> so us grub2
Mar 21 02:01:45 <GenTooMan> is even
Mar 21 02:01:59 <nerdboy> gparted livecd does boot correctly for grub2 uefi install
Mar 21 02:02:12 <nerdboy> or manual repair
Mar 21 02:02:43 <nerdboy> and grub2 doesn't make it less paiful...
Mar 21 02:02:50 <nerdboy> *painful even
Mar 21 02:03:03 <ds2> someone needs to make PCs with u-boot
Mar 21 02:04:13 <GenTooMan> couldn't get it to boot right under my asus board I installed in november. Then it refused too boot at all the livedvd (sigh). the UEFI can make things more complicated at the same time I noticed.
Mar 21 02:04:30 <nerdboy> down to 195 packages
Mar 21 02:04:43 <veremit> sysrescuecd ftw
Mar 21 02:04:52 <veremit> grub2 kinda works ..
Mar 21 02:04:55 <nerdboy> gparted
Mar 21 02:05:05 <veremit> gparted is on sysrescd
Mar 21 02:05:18 <nerdboy> better interface
Mar 21 02:06:00 <nerdboy> you do have to unhork ssh a little to log in remotely
Mar 21 02:06:46 <veremit> gotta set pwd and start ssh on sysrescd .. but it works as long as you got a display attache
Mar 21 02:06:49 <veremit> +d
Mar 21 02:07:22 <nerdboy> gparted also needs tcpwwrappers disabled
Mar 21 02:07:56 <veremit> lots of good stuff on sysrescd .. and its gentoo-based :)
Mar 21 02:10:28 <veremit> I have to confess to bein lazy and using linaro .. so if you find the crosstool config .. pls post it :)
Mar 21 02:11:15 <veremit> I think it will still work with RN's scripts too if you specify the CC :)
Mar 21 02:15:57 <GenTooMan> hmmm probably something to do tomorrow
