**** BEGIN LOGGING AT Thu Jun 19 02:59:59 2014
Jun 19 05:58:21 <rajib> hello
Jun 19 06:00:04 <rajib_> anyone there who can help me exploring info about beaglebone?
Jun 19 06:00:48 <jkridner> rajib_: you have to ask a question and be patient.
Jun 19 06:02:25 <rajib_> okay.sure
Jun 19 06:02:26 <jkridner> rajib_: as in, a question with an answer.
Jun 19 06:03:13 <rajib_> I want to know information about number of analog,digital i/o pins on beagleboard
Jun 19 06:03:27 <jkridner> http://beagleboard.org/black ?
Jun 19 06:04:04 <jkridner> http://beagleboard.org/support/bone101/#headers
Jun 19 06:04:22 <rajib_> this one http://beagleboard.org/Products/BeagleBone
Jun 19 06:05:21 <jkridner> k, the original (more expensive) BeagleBone?
Jun 19 06:05:35 <jkridner> headers are the same, but the HDMI/eMMC pins aren't reserved on it.
Jun 19 06:05:50 <jkridner> (because it doesn't have HDMI/eMMC)
Jun 19 06:07:23 <rajib_> Okay.The one you referred earlier is good
Jun 19 06:08:05 <rajib_> I am not clear about how to program these boards,can you please enlighten me?
Jun 19 06:08:18 <jkridner> rajib_: do you know how to program a computer?
Jun 19 06:08:31 <jkridner> say, a Linux desktop or Android mobile computer?
Jun 19 06:09:48 <rajib_> program a computer means as in developing an application ?
Jun 19 06:09:49 <jkridner> (Python, JavaScript, Java, C, C++, Perl, Go, Closure, Erlang, ...)
Jun 19 06:10:09 <jkridner> application, driver, script, whatever.
Jun 19 06:10:46 <jkridner> These are just Linux computers and they support the tools other Linux computers support.... they just happen to have a lot of extra I/O capabilities.
Jun 19 06:11:32 <jkridner> Maybe you should buy a book: http://elinux.org/Beagleboard:BeagleBoneBlack#books
Jun 19 06:11:50 <rajib_> so if i want to do an project then i will have to develope an application right?
Jun 19 06:11:59 <jkridner> er http://elinux.org/Beagleboard:BeagleBoneBlack#Books
Jun 19 06:12:02 <rajib_> Thanks for the book.I will read that
Jun 19 06:12:34 <jkridner> You have to create a program... I'm not sure what you are trying to imply by "application"
Jun 19 06:12:35 <rajib_> I read somewhere it supports arduino programming capabilities?
Jun 19 06:12:56 <jkridner> rajib_: yes, http://elinux.org/Userspace_Arduino
Jun 19 06:13:19 <jkridner> you don't have to do all the setup stuff on that page...
Jun 19 06:13:24 <rajib_> As in case of microcontrollers we write a program in their softwares
Jun 19 06:13:27 <jkridner> you can just type code into the Cloud9 IDE and hit run.
Jun 19 06:15:58 <rajib_> out of all gpio pins they are divided again for different developement platforms,right?
Jun 19 06:18:00 <jkridner> "divided again"?
Jun 19 06:25:53 <rajib_> i am not sure ,just asking
Jun 19 06:26:33 <rajib_> All the gpio pins can be used in all platforms like linux,arduino etc...
Jun 19 06:26:37 <KotH> rajib_: get the "embdded linux primer" by hallinan
Jun 19 06:26:58 <KotH> rajib_: also reading the TRM should enlighten you
Jun 19 06:27:14 <jkridner> KotH: it doesn't sound like rajib_ would understand the TRM
Jun 19 06:27:26 <KotH> oh.. right, sorry
Jun 19 06:27:38 <KotH> rajib_: technical reference manual of the AM335x
Jun 19 06:27:46 <KotH> rajib_: to be found somewhere on ti.com
Jun 19 06:28:42 <rajib_> Can you just tellme the easiest way to get started ,i mean easiest platform?
Jun 19 06:29:04 <jkridner> rajib_: perhaps you should start with an Arduino
Jun 19 06:29:13 <jkridner> http://arduino.cc
Jun 19 06:29:32 <rajib_> I have a very good knowledge using  arduino
Jun 19 06:29:32 * KotH nods
Jun 19 06:29:39 <jkridner> BeagleBone *can* be easy, but there isn't "one way" (tm)
Jun 19 06:29:54 <KotH> BB can be very complex
Jun 19 06:30:04 <KotH> depending on what you want to do and how you want to do it
Jun 19 06:30:08 <rajib_> I am not worried about that
Jun 19 06:30:14 <jkridner> you can learn from using a BeagleBone Black....
Jun 19 06:30:29 <RagBal> Can anybody help me reverse the polarity of the LCD pixel clock?
Jun 19 06:30:42 <jkridner> start by plugging it in and doing the built-in JavaScript tutorials... http://beagleboard.org/Support/bonescript
Jun 19 06:30:50 <rajib_> I want to do a project which involoves use of digital i/os,analog i/o,spi,ethernet,i2c communications
Jun 19 06:30:58 <jkridner> then, start to look at the source and understand how Linux abstracts the hardware as files...
Jun 19 06:31:16 <jkridner> that book KotH recommended is a great addition!
Jun 19 06:31:26 <jkridner> it'll help you understand what Linux is doing...
Jun 19 06:31:40 <jkridner> then, eventually, you can start adding in PRU code to get real-time stuff going.
Jun 19 06:31:44 <jkridner> that's my roadmap for you.
Jun 19 06:31:54 <rajib_> what is PRU ?
Jun 19 06:32:08 <jkridner> you'll know before you are ready. :-)
Jun 19 06:32:49 <jkridner> google is your friend
Jun 19 06:32:57 <rajib_> Okay,thanks
Jun 19 06:42:42 <RagBal> Any leads on reversing the LCD pixel clock polarity?
Jun 19 06:52:08 <jkridner> RagBal: might help to google invert-frm-clock and panel-info
Jun 19 06:52:51 <jkridner> doc seems to be here: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/drm/tilcdc/panel.txt
Jun 19 06:54:38 <jkridner> https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/video/display-timing.txt seems to have the setting you need.
Jun 19 06:55:36 <RagBal> jkridner, thank you for the push in the right direction
Jun 19 06:56:22 <RagBal> I don't use the DRM driver though, only fbdev
Jun 19 06:57:14 <jkridner> display-timing should still be the same.
Jun 19 06:57:21 <jkridner> which board?
Jun 19 06:57:30 <RagBal> BBB
Jun 19 06:57:40 <jkridner> sure you aren't using the DRM driver?
Jun 19 06:57:44 <jkridner> 3.8 kernel or newer?
Jun 19 06:58:05 * jkridner suspects fbdev mode of DRM driver
Jun 19 06:58:17 <RagBal> But pixelclk-active doesn't modify the hardware clock, only tells the driver that the data is on active low or high pulses, right?
Jun 19 06:58:33 <RagBal> jkridner, it's a BBB referenced design board, kernel 3.12
Jun 19 06:58:54 <RagBal> Haven't gotten DRM to function yet
Jun 19 06:59:14 <jkridner> easy enough to look at the driver source and see, but I suspect the driver does modify the clock.
Jun 19 07:00:59 <RagBal> jkridner, thanks I'll have a look
Jun 19 07:01:07 <jkridner> https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/video/of_display_timing.c#n87
Jun 19 07:02:02 <RagBal> Ahh there is the reg =)
Jun 19 07:03:11 <RagBal> jkridner, thanks, my assumption about pixelclk-active was wrong
Jun 19 07:09:01 <jkridner> RagBal: http://lxr.free-electrons.com/source/drivers/gpu/drm/tilcdc/tilcdc_crtc.c#L361
Jun 19 07:10:34 <RagBal> jkridner, is there a way to check its current setting from within Linux?
Jun 19 07:14:41 <jkridner> RagBal: not sure if /proc/device-tree/ocp/lcdc@4830e000 will have anything useful.
Jun 19 07:14:57 <jkridner> fbset returns bogus timing values
Jun 19 07:15:43 <RagBal> jkridner, it returns bogus info? my geometry settings seem to be correct in there
Jun 19 07:16:01 <jkridner> geometry should be right, but timings don't come back right for some reason.
Jun 19 07:17:21 <treeherder> has anyone here compiled opencv on the bbb in debian?  could you maybe give me a hint as to why my ffmpeg is getting flagged as deprecated?
Jun 19 07:17:53 <jkridner> treeherder: the opencv that comes on the the default Debian image doesn't have the features you need?
Jun 19 07:17:58 <woglinde> why should I compile opencv? I would do apt-get install
Jun 19 07:18:23 <jkridner> woglinde: I'd do even less because I know it is already 'apt-get install'd
Jun 19 07:18:35 * jkridner heads to bed.
Jun 19 07:18:42 <tbr> jkridner: preempting all the people crying for it, nice
Jun 19 07:18:49 <woglinde> gn jkridner
Jun 19 07:19:56 <treeherder> jkridner, i was just compiling because i built my own debian
Jun 19 07:20:20 <jkridner> doesn't mean you can't apt-get the binaries, does it?
Jun 19 07:20:25 <woglinde> poor guy and waste of time
Jun 19 07:20:39 <RagBal> jkridner, what I'm trying to fix is a LCD display that has blurry images, timings in device tree seem to be correct and are identical with somebody elses values. Only difference between us is the fbset geometry output shows "800 480 800 960 32" instead of "800 480 800 480 32"
Jun 19 07:20:49 <woglinde> you only get 10% in vfp in special cases
Jun 19 07:20:59 <RagBal> While the timings are identical... what else could cause the difference?
Jun 19 07:21:18 <Guest78278> hello every one,i m connecting webcam and 2 stpper motor at same time with bbb so camera stop working and when i reboot the system and unplugged the stepper motor then it start working, do u know how can i solve that problem
Jun 19 07:22:56 <Guest78278> can any one help me
Jun 19 07:22:59 <treeherder> probably too much power draw on the motors
Jun 19 07:23:04 <treeherder> do they share a power source?>
Jun 19 07:23:13 <Guest78278> nop
Jun 19 07:24:13 <treeherder> what's the power draw from the stepper controller
Jun 19 07:41:02 <rahul> heyi m connecting webcam and 2 stpper motor at same time with bbb so camera stop working and when i reboot the system and unplugged the stepper motor then it start working, do u know how can i solve that problem
Jun 19 08:14:39 <treeherder> jkridner, ok using the builtin opencv i can't seem to get any of the libfreenect scripts to work
Jun 19 08:14:50 <treeherder> and i get the same deprecation error when trying to compile
Jun 19 08:35:12 <chandan_> hey
Jun 19 08:35:35 <Guest34541> hello guys, i m connecting webcam and 2 stpper motor at same time with bbb so camera stop working and when i reboot the system and unplugged the stepper motor then it start working, do u one know ,how can i solve that problem
Jun 19 08:36:23 <tbr> how are you powering the board?
Jun 19 08:37:27 <Guest34541> i m using usb power
Jun 19 08:37:34 <Guest34541> and i also connect
Jun 19 08:37:41 <Guest34541> 5v 2.5ma
Jun 19 08:37:43 <Guest34541> supply
Jun 19 08:39:13 <tbr> how is the 5V 2.5A power supply connected to the BBB?
Jun 19 08:40:39 <Guest34541> threw power port
Jun 19 08:41:27 <tbr> ok, and how do you connect the stepper motor to the BBB? does it have a separate power supply?
Jun 19 08:41:43 <Guest34541> i m using
Jun 19 08:41:44 <Guest34541> https://www.sparkfun.com/products/10267
Jun 19 08:41:47 <Guest34541> this
Jun 19 08:44:54 <tbr> ok and what do you exactly mean with "the camera stops working"?
Jun 19 08:46:01 <Guest34541> i have a camera with leds means if i give coonect to it with usb port leds are on
Jun 19 08:46:17 <Guest34541> first i coonect camera to bbb
Jun 19 08:46:25 <Guest34541> and then when i connecting
Jun 19 08:46:31 <Guest34541> 5v supply for stepper
Jun 19 08:46:39 <Guest34541> then that led off
Jun 19 08:46:46 <Guest34541> and when i run code for taking image
Jun 19 08:46:57 <Guest34541> the it showing some v4l2 error
Jun 19 08:49:08 <tbr> sounds like you're overloading the power supply
Jun 19 08:49:23 <tbr> use a separate supply for the stepper
Jun 19 08:49:29 <Guest34541> ok
Jun 19 08:49:38 <Guest34541> when i m using seprate supply
Jun 19 08:49:44 <Guest34541> then it's working
Jun 19 08:49:57 <tbr> good, problem solved then.
Jun 19 08:50:07 <Guest34541> but is this poosibe to do my work without using external supply
Jun 19 08:55:56 <raa> hey
Jun 19 08:56:13 <raa> i want to connect dongle with beaglebone black
Jun 19 08:56:24 <raa> i m using sakis3g
Jun 19 08:56:29 <raa> but it's not working
Jun 19 08:59:15 <xy_> i want to install debian in bbb, but i m unable to do when i plugged the sd card and  press boot button
Jun 19 08:59:30 <xy_> then the usr leds are always off
Jun 19 09:26:00 <tbr> xy_: sounds like you didn't prepare the card correctly
Jun 19 09:26:08 <tbr> raa: what sort of dongle?
Jun 19 09:26:25 <xy_> airtel
Jun 19 09:26:30 <xy_> airtell4g
Jun 19 09:27:19 <tbr> your sd card is an airtel4g?
Jun 19 09:29:44 <raa> i prepared the sd card corectly
Jun 19 09:30:37 <tbr> are you two guys on the same group/team or something?
Jun 19 09:31:02 <xy_> actully we are the project parteners
Jun 19 09:31:11 <xy_> that's why we know
Jun 19 09:32:13 <xy_> i preapred the card corectly using 7 zip and win32 disk image
Jun 19 09:34:30 <xy_> u know how can we solve it
Jun 19 09:34:52 <tbr> if you prepared the card correctly, then the board would boot
Jun 19 09:35:13 <xy_> ya
Jun 19 09:35:20 <xy_> but now working
Jun 19 09:35:26 <xy_> so how can i do that
Jun 19 09:35:55 <tbr> do you have a linux machine available?
Jun 19 09:36:40 <xy_> ya
Jun 19 09:37:20 <woglinde> connect serial cable
Jun 19 09:37:28 <woglinde> to see whats gooing on
Jun 19 09:37:55 <xy_> ok
Jun 19 09:37:59 <tbr> and prepare the card using a linux machine
Jun 19 09:38:10 <xy_> when i connect the sd card on bbb
Jun 19 09:38:21 <xy_> and press boot key
Jun 19 09:38:33 <xy_> then the usr leds are always off
Jun 19 09:42:29 <tbr> card not bootable, redo card properly on linux.
Jun 19 09:42:37 * tbr wont repeat himself again
Jun 19 09:43:12 <xy_> ok
Jun 19 09:44:03 <woglinde> tbr how do you know this if you do not see the boot messages?
Jun 19 09:44:27 <tbr> woglinde: IIRC there should be at least some leds coming up even in uboot
Jun 19 09:44:30 <woglinde> using a serial cable to see whats going on is a must
Jun 19 09:44:44 <woglinde> tbr if the hw is broken?
Jun 19 09:44:58 <tbr> well, then nothing can help
Jun 19 09:45:10 <tbr> xy_: does the board boot without the card?
Jun 19 09:45:47 <xy_> y
Jun 19 09:45:48 <xy_> ya
Jun 19 09:45:58 <tbr> woglinde: so, hw is ok
Jun 19 09:46:07 <tbr> xy_: which image are you trying?
Jun 19 09:47:31 <xy_> debiaan
Jun 19 09:47:49 <tbr> xy_: where from, can you point us to the download page?
Jun 19 09:49:57 <xy_> ok
Jun 19 09:49:58 <xy_> wait
Jun 19 09:51:22 <xy_> http://beagleboard.org/latest-images
Jun 19 09:54:30 <xy_> tbr_ from here
Jun 19 09:56:37 <JetForMe> Hi there. Anyone know how I can use SDL with BBB and the 4D 4.3" LCD cape?
Jun 19 09:57:35 <woglinde> JetForMe why not?
Jun 19 09:57:53 <woglinde> if you get some output on a display sdl will work
Jun 19 09:57:54 <tbr> xy_: ok, and which one of those images?
Jun 19 09:58:14 <JetForMe> I've written a basic SDL program, but I get an error when it tries to create a window: SDL_Error: No available video device
Jun 19 09:58:19 <xy_> debian eem
Jun 19 09:59:04 <woglinde> JetForMe hm use strace to see what sdl will open
Jun 19 09:59:06 <JetForMe> Debian boots just fine, and displays a desktop on it, but I want to completely take over the screen (it's going to be an information display)
Jun 19 09:59:31 <woglinde> JetForMe and which sdl version 2.x?
Jun 19 09:59:40 <JetForMe> affimative
Jun 19 09:59:44 <JetForMe> I built it from sources
Jun 19 09:59:58 <xy_> i m not using dektop
Jun 19 10:00:08 <xy_> i m connect it with my laptop
Jun 19 10:00:51 <JetForMe> woglinde: I'm not sure what to look for in the strace output...
Jun 19 10:02:43 <woglinde> JetForMe look for /dev
Jun 19 10:03:04 <JetForMe> woglinde: strace output: https://pastee.org/hgu9a  my code: https://pastee.org/2b2ad
Jun 19 10:03:28 <JetForMe> No /dev that I see. closest is fstat64(1, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0), ...}) = 0
Jun 19 10:04:50 <woglinde> jetforme yes strange
Jun 19 10:05:08 <woglinde> lookup what dev 136 major 0 minor is
Jun 19 10:05:11 <woglinde> lunch now
Jun 19 10:05:13 <JetForMe> Does it depend on X or something like that?
Jun 19 10:05:18 <woglinde> no
Jun 19 10:05:24 <JetForMe> Thanks. It's 3 am here. I'm going to bed.
Jun 19 10:05:28 <woglinde> sdl should work with framebuffer only too
Jun 19 10:05:36 <woglinde> maybee you need to configure it
Jun 19 10:05:40 <JetForMe> Okay.
Jun 19 10:05:45 <woglinde> I know sdl only in some parts
Jun 19 10:05:49 <JetForMe> Not really sure how to do that. I'm mostly a Cocoa/iOS guy
Jun 19 10:06:02 <woglinde> documenation will hellp
Jun 19 10:06:06 <woglinde> good night
Jun 19 10:06:15 <JetForMe> No worries. IF you can suggest what documentation to read, I'll take a look
Jun 19 10:06:23 <JetForMe> My googling has so far turned up nothing
Jun 19 10:09:00 <thurgood> I think you have to use `fbset >> /etc/fbmode` to get it to work in console
Jun 19 10:09:11 <thurgood> or somesuch
Jun 19 10:09:25 <JetForMe> thurgood: is that for me?
Jun 19 10:10:13 <thurgood> yes
Jun 19 10:10:32 <thurgood> just have to do that once
Jun 19 10:11:09 <JetForMe> There is an /etc/fb.modes, but no /etc/fbmode
Jun 19 10:11:21 <thurgood> yeah, that's the one
Jun 19 10:13:24 <JetForMe> thurgood: Do I need to restart or something? That didn't ahve any effect, although I did see i was using the wrong window dimensions (I think)
Jun 19 10:13:34 <JetForMe> It doesn't seem to make a difference
Jun 19 10:14:19 <thurgood> what's your sdl initalization look like in code?
Jun 19 10:14:33 <thurgood> (use pastebin)
Jun 19 10:14:37 <JetForMe> https://pastee.org/2b2ad
Jun 19 10:14:55 <JetForMe> (I've since changed the dimensions to 480x272)
Jun 19 10:20:28 <JetForMe> thurgood: Anything jump out at you? What's your timezone? I'm about to pass out here.
Jun 19 10:20:39 <JetForMe> Gonna head to bed. I'll try again in the morning
Jun 19 10:22:25 <thurgood> not immediately, do you get an error at all?
Jun 19 10:23:03 <thurgood> I'm more familiar with SDL 1.2
Jun 19 10:25:47 <Johan_____> jkfjksd
Jun 19 10:26:24 <Johan_____> I'm looking to buy a beaglebone black in south africa. how do i do this?
Jun 19 10:28:32 <JetForMe> thurgood: Just what SDL reports: "No available video device"
Jun 19 10:30:18 <thurgood> try correcting your dimensions and use 0 for instead of SDL_WINDOW_SHOWN
Jun 19 10:30:56 <thurgood> you'll probably need a renderer if you get past that as well
Jun 19 10:31:17 <JetForMe> fbset outputs: https://pastee.org/s39cs
Jun 19 10:31:51 <JetForMe> I've already changed my code to this (480x272): https://pastee.org/y545z
Jun 19 10:32:04 <JetForMe> same result
Jun 19 10:32:22 <thurgood> ah, not a standard monitor?
Jun 19 10:32:48 <JetForMe> it's this: http://www.4dsystems.com.au/product/4DCAPE_43/
Jun 19 10:33:38 <JetForMe> It totally works. There's a desktop showing on it right now. When it boots, it shows the console text, etc.
Jun 19 10:36:12 <thurgood> did SDL_Init succeed?
Jun 19 10:36:20 <JetForMe> Oh, let me verify
Jun 19 10:37:39 <JetForMe> thurgood: SDL_Init fails, same error ("No available video device")
Jun 19 10:38:27 <thurgood> are you in the console or in the desktop?
Jun 19 10:38:55 <JetForMe> I'm logged in via SSh. I've also tried this in a terminal app on the desktop
Jun 19 10:39:15 <JetForMe> I have not tried with a console
Jun 19 10:39:27 <thurgood> oh, there is no display in ssh by default
Jun 19 10:39:39 <JetForMe> Ah. How do I set one?
Jun 19 10:40:17 <thurgood> I can't remember but it involves tunneling I believe
Jun 19 10:40:28 <JetForMe> That sounds like an X-windows thing
Jun 19 10:40:53 <thurgood> I would suggest running from the console and seeing what you get
Jun 19 10:41:23 <JetForMe> Interestingly, I tried export DISPLAY=:0, and then ran, and first it output "No protocol specified", then gave me the same error
Jun 19 10:41:32 <thurgood> just to elimiate other issues
Jun 19 10:41:49 <JetForMe> I'll try to connect the cable. With the LCD attached, there might not be enough room
Jun 19 10:45:30 <thurgood> if you need to use ssh, use the -X option as well
Jun 19 10:48:36 <JetForMe> same results via console
Jun 19 10:48:58 <JetForMe> ssh -X starts X-windows on my Mac, not what I want to accomplish
Jun 19 10:49:35 <JetForMe> By the way, if I run my app, it creates a window on my Mac ;-)
Jun 19 10:49:45 <JetForMe> but I need to take over the LCD, so that's not what I'm looking for.
Jun 19 10:50:40 <JetForMe> woglinde: said something about it being able to work "framebuffer only", no X needed.
Jun 19 10:50:49 <JetForMe> really gotta give up on this for now. Thanks for your help!
Jun 19 10:51:16 <thurgood> ok, it does work framebuffer only, that's how I use 1.2
Jun 19 10:51:51 <JetForMe> Hrm. Apparently not 2.0: http://forums.libsdl.org/viewtopic.php?t=9661&sid=47b3f4fde203ea5710a798bb6093b8dd
Jun 19 10:52:45 <thurgood> then I would suggest using 1.2 if you're just getting started
Jun 19 10:52:59 <JetForMe> Okay. Can I render TTF fonts with that?
Jun 19 10:53:11 <JetForMe> Do you have a simple example I can reference?
Jun 19 10:55:30 <JetForMe> Ah!
Jun 19 10:56:08 <JetForMe> thurgood: I tried passing SDL_WINDOW_OPENGL to the createWindow call, and now the error is Couldn't find matching GLX visual
Jun 19 10:56:30 <woglinde> *sigh*
Jun 19 10:56:49 <thurgood> the black kernel does not support GL
Jun 19 10:57:23 <JetForMe> Wow, really?
Jun 19 10:57:25 <thurgood> yes to TTF use sdl_ttf
Jun 19 10:58:01 <woglinde> hm really to bad there is no FBDEV driver for sdl 2.0
Jun 19 10:58:20 <woglinde> getting EGL running on the sgx with newer kernels is complicated
Jun 19 10:58:21 <JetForMe> okay. I'll have to try to find a 1.2 example hellow world
Jun 19 10:58:28 <thurgood> there's probably a 2 in the name as well
Jun 19 10:58:58 <JetForMe> thanks for the help, guys. I'm gonna be a zombie tomorrow in my morning meetings. Good night!
Jun 19 10:59:32 <thurgood> heh, g'night
Jun 19 13:01:10 <psino> does anyone know of a guide to upgrading the beaglebone black version using an usb-stick instead of a micro-sd card? or isn't that possible?
Jun 19 13:02:04 <psino> I've tried digging through the uEnv.txt-file on the eMMC-flashers boot partition, but looking at all the references to mmc, I'm just not sure what should be changed and what should stay the same
Jun 19 13:03:10 <psino> the reason I'm trying to do it this way is that I currently don't have a micro-sd card, and wondering if it still can be done
Jun 19 13:08:10 <woglinde> psion what os do you want to update?
Jun 19 13:13:53 <psino> woglinde: angstrom (cloud9 gnome image 2013.09.04) to debian
Jun 19 13:16:50 <woglinde> thats not an update
Jun 19 13:31:31 <midihenry> hello
Jun 19 13:32:17 <midihenry> could someone please tell me if the element14 beaglebone black clone is safe ?
Jun 19 13:34:50 <midihenry> are there any major differences between the community and the element14 edition?
Jun 19 13:35:03 <midihenry> especially when it comes to hardware?
Jun 19 16:12:23 <gwilson> I posted a question last night about moving a custom cape project from Angstrom to Debian. I'm getting a message about the .dtbo failed to load.
Jun 19 16:12:33 <gwilson> jkridner asked to see the dmesg log and I pasted it here: http://pastebin.com/2yTcCsh6 Any other pointers on what to look for would be appreciated.
Jun 19 16:12:59 <jkridner> gwilson: on a call right now... will look in a bit
Jun 19 16:13:08 <gwilson> Thanks
Jun 19 16:52:09 <rcn-ee> gwilson, what happens when you disable hdmi/hdmin/eMMC and then load your cape into slots from userspace?
Jun 19 17:10:54 <gwilson> rcn-ee: Haven't tried that, I would have to disable the hdmi stuff in the linux command line? or can I do that from userspace?
Jun 19 17:12:18 <rcn-ee> gwilson, there should be a line in /boot/uboot/uEnv.txt that looks like: https://github.com/beagleboard/image-builder/blob/master/target/boot/beagleboard.org.txt#L15 (just uncomment it)
Jun 19 17:14:01 <gwilson> rcn-ee, got it, will try
Jun 19 17:20:45 <gwilson> rcn-ee: after booting with hdmi/hdmin/eMMC disabled, I still get the can't load message, but when I manually echo cape to slots, it loads and LCD works
Jun 19 17:22:20 <rcn-ee> gwilson, okay, next add that same "echo cape >" cape name to "/etc/default/capemgr" with the "CAPE=" and reboot, should load pretty soon on startup.
Jun 19 17:24:09 <rcn-ee> gwilson,  your basicly fighting against this: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Loading_custom_capes
Jun 19 17:26:08 <gwilson> rcn-ee: got it, will try that next, thanks
Jun 19 17:30:18 <gwilson> rcn-ee: that seems to have done it, thanks for the help, so hard to keep track of all of the nooks and crannies.
Jun 19 17:31:07 <rcn-ee> not a problem, that issue is probally the biggest angstrom -> debian conversion issue. ;)
Jun 19 17:32:46 <gwilson> rcn-ee: and here I thought I couldn't have read more doc. guess it's not possible.
Jun 19 17:33:31 <rcn-ee> i tried to make that one easy to find, as the base elinux address is spamed on serial/ssh. ;)
Jun 19 17:51:21 <xD1845> I am looking for an Ubuntu 12.04 minimal fs, and can't find one on https://rcn-ee.net/deb/minfs — only the newer ones are there. Does anyone have a copy of a 12.04 minimal fs?
Jun 19 17:52:03 <xD1845> (arm-hf)
Jun 19 17:53:32 <Dark-Fx> those are probably built by someone other than ubuntu.
Jun 19 17:53:50 <xD1845> There used to be a "precise" directory on http://rcn-ee.net/deb/minfs/ but it is no longer there
Jun 19 17:54:37 <agmlego> Why so old?
Jun 19 17:55:31 <xD1845> I am having an issue compiling software since "libudev0" package is not available in 14.04
Jun 19 18:01:45 <agmlego> And yopu cannot update the software to use the newer library revision?
Jun 19 18:04:54 <xD1845> Compiling the software from source and it looks for that library, which apparently has changed names also.
Jun 19 18:05:47 <xD1845> Just curious, do you use a cross compiling environment or compile everything on the beagle?
Jun 19 18:14:06 <agmlego> xD1845: Who was that targeted at?
Jun 19 18:14:47 <xD1845> agmlego: do you use a cross compiling environment or compile everything on the beagle?
Jun 19 18:15:04 <agmlego> xD1845: Neither.
Jun 19 18:19:13 <Tony> hi
Jun 19 18:19:41 <Tony> i have a question, can i connect two cameras cape to beaglebone?
Jun 19 19:05:04 <JetForMe> So, the SDL folks tell me that there's some legal/technical issue with Open GL ES on BeagleBone Black, and that's why SDL2 doesn't work on it. But I should be able to use Wayland or X. Any recommendations on one or the other?
Jun 19 19:06:59 <rcn-ee> wayland or X doesn't work yet. either..  fbdev works great thou.. ;)
Jun 19 19:07:55 <JetForMe> rcn-ee: Thanks. I wish I knew what that meant. My Linux knowledge is very limited. What's fbdev? How do I use it? I just want to draw some 2D text and graphics, taking over the whole LCD that's attached to my BBB.
Jun 19 19:08:48 <rcn-ee> fbdev, is software rendering..
Jun 19 19:09:10 <JetForMe> That's prrobably sufficient for my needs. It's just an information display, no need for high frame rates
Jun 19 19:09:21 <JetForMe> Is it something I can use with SDL2?
Jun 19 19:09:23 <andrewrk> what do you typically use for persistent storage for the BBB ?
Jun 19 19:10:31 <Defiant> the Cloud?
Jun 19 19:10:52 <rcn-ee> sdl2 doesn't support the raw framebuffer
Jun 19 19:11:01 <andrewrk> Defiant, not if I'm turning it into a music player
Jun 19 19:11:25 <torque> a microsd card, probably
Jun 19 19:13:00 <JetForMe> rcn-ee: So, SDL 1.2, then?
Jun 19 19:13:42 <andrewrk> torque, oh, I did not see that it has a micro sd card slot
Jun 19 19:14:11 <rcn-ee> JetForMe, yeap, or use software rendering from mesa..
Jun 19 19:14:41 <torque> it does, on the bottom
Jun 19 19:15:12 <andrewrk> cool
Jun 19 19:15:20 <thurgood> the black doesn't do gles, or have you got a kernell with it integrated?
Jun 19 19:16:26 <thurgood> oh, mesa... that would be slower
Jun 19 19:16:47 <rcn-ee> it does gles in fbdev mode, but he's using a cape, which i don't have support for in my v3.13.x kernel. ;)
Jun 19 19:18:13 <thurgood> Jet the issue, afaik with gles and the black is that the 3.8 kernel changed the dss interface in ways that made it incompatible with the gles drivers that exist
Jun 19 19:18:23 <andrewrk> I'm writing a guide on how to install my music player app on a raspberry pi.
Jun 19 19:18:31 <andrewrk> you know why there's no guide on how to install it on the beagle?
Jun 19 19:18:39 <andrewrk> because it's just `apt-get install my-app`
Jun 19 19:18:53 <thurgood> oh, so you got it working in 3.13 on the black?
Jun 19 19:19:13 <xD1845> andrewrk: Are you writing a cross compilation guide?
Jun 19 19:19:24 <thurgood> rcn-ee: I'll have to give that a try when (if) I get a chance
Jun 19 19:19:49 <andrewrk> xD1845, nah, it's more just like "this is the compile options you have to give to each dependency before installing"
Jun 19 19:20:20 <rcn-ee> thurgood, more of 'finally' wrote up what i got working back in december-ish: https://plus.google.com/106813818225399872098/posts/ZC9TEYjJNfP http://elinux.org/BeagleBoardDebian#SGX_BeagleBone.2FBeagleBone_Black as people started asking about it again.
Jun 19 19:20:33 <andrewrk> whereas with the BBB, I just set up a PPA on launchpad and everything is done for you
Jun 19 19:20:41 <xD1845> That's sweet
Jun 19 19:20:58 <Defiant> andrewrk: I would have guessed because the BBB has no Audio out
Jun 19 19:21:19 <andrewrk> oh shit, is that true? I need that
Jun 19 19:21:36 <andrewrk> hmm I guess HDMI counts as audio out
Jun 19 19:21:47 <andrewrk> but it's harder to find speakers that accept hdmi in
Jun 19 19:21:50 <Defiant> If you can use the HDMI output on your speakers
Jun 19 19:22:46 <andrewrk> if the speakers supported it, that would be better anyway, since analog out tends to have interference
Jun 19 19:25:25 <Defiant> USB Sound card would be cheaper
Jun 19 19:27:39 <andrewrk> cheaper than what?
Jun 19 19:30:19 <Defiant> new speakers
Jun 19 19:30:59 <andrewrk> ah, yes
Jun 19 19:39:17 <thurgood> rcn-ee: this doesn't require bufferclass_ti?
Jun 19 19:42:18 <rcn-ee> i only ever saw that on the omap35/37 stuff..
Jun 19 19:43:24 <thurgood> ah, ok
Jun 19 21:16:56 <gwilson_> looks like I'm goint to have to package up my own debian system, I've got a wandboard and have already built a copy of debian, but I need to modify the package list, how do I include 'wheezy-backports' to get libudev1 in the .package file?
Jun 19 21:17:26 <coreyfro> Hey all. Is beaglescript going to be a part of the new debian build? I want to teach a class on embedded hardware and cloud 9 would be attractive.
Jun 19 21:19:37 <gwilson_> not .package but .project, it will never work if I can't figure out what file I need to modify
Jun 19 21:26:03 <coreyfro> gwilson_ Hey, I use multistrap to build images for my company.  Let me pastbin my configs
Jun 19 21:26:10 <rcn-ee> gwilson_, enable this flag on head of the sscript: https://github.com/beagleboard/image-builder/blob/master/scripts/chroot.sh#L240
Jun 19 21:26:22 <coreyfro> Or do that
Jun 19 21:26:25 <coreyfro> ;-)
Jun 19 21:27:16 <rcn-ee> coreyfro, bonescript is part of the debian image. ;) we had to make it easy for existing users to move over. ;)
Jun 19 21:27:53 <coreyfro> Hey RCN-EE, I am working with your linux-dev build.  I tried 3.16 today but it didn't boot. didn't even load the kernel.  3.14 works just fine.  Is this to be expected?
Jun 19 21:28:00 <coreyfro> rcn-ee THANKS!!!!
Jun 19 21:29:32 <coreyfro> RCN-EE I have the drivers (3.0.0.3 and 3.0.0.4) for Meditek MT7601U FINALLY compiling on all versions after 3.12, but all 3.14 and later kernels run super slow.  Have you played with this 802.11 adapter?
Jun 19 21:29:34 <rcn-ee> i usually don't test "-rc1's", mostly making sure they build..
Jun 19 21:29:47 <coreyfro> Awesome.  They build ;-)
Jun 19 21:30:14 <rcn-ee> i actually don't have any MT7601U devices. ;)
Jun 19 21:30:27 <coreyfro> OK, just curious
Jun 19 21:30:50 <coreyfro> thanks for you hard work, linux-dev kicks butt
Jun 19 21:30:59 <rcn-ee> but v3.15.x should boot, i switched the beta channel for the bone from v3.14.x to v3.15.x.. pretty stable on my bone's so far..
Jun 19 21:31:54 <rcn-ee> ps, i moved the "bone" part of linux-dev into bb-kernel.. less noise for users, as i pound on master of linux-dev daily. ;)
Jun 19 21:31:55 <coreyfro> I'm aiming for 3.14 because it fixes the babble bug, (YAY!) BUT the drivers for our adapter don't work, so I need to commune with Mediatek to figure out what comes next
Jun 19 21:32:28 <coreyfro> Are they functionally different?
Jun 19 21:33:03 <rcn-ee> bb-kernel was an exact clone of linux-dev on the day i created it.. i just haved pushed any of those branches from bb-kernel to linux-dev
Jun 19 21:34:29 <coreyfro> OK, I'm doing great with linux-dev, so if there isn't a reason, other than noise, to move over, I'll stick with it
Jun 19 21:39:52 <rcn-ee> has anyone played around with java 8, specifically triggering -Djavafx.platform=eglfb?
Jun 19 21:42:15 <aleandros> Hi people! I was wondering if someone could point me to a device tree overlay that uses 6 PWM pins, since I'm sure I'm not doing it right.
Jun 19 21:42:23 <agmlego> Yeah. I accidentally created a small black hole in my work area, out of which the unspeakable horror began to crawl. I was filled immediately with a maroon miasma of dread and hopelessness, and quickly removed power to the device, banishing the horror once again.
Jun 19 21:42:40 <agmlego> I filed a bug report, but the maintainersa closed it with wontfix.
Jun 19 21:43:16 <agmlego> I recommend waiting until they can be convinced to fix that issue before enabling the option.
Jun 19 22:22:32 <nate`> meh my beagle didn't come in today
Jun 19 22:22:46 <nate`> hope tomorrow or else this is gonna be a horrible fathom of boredom
Jun 19 22:26:50 <mjgardes> agmlego: because that's a feature
Jun 19 23:27:43 <Eliel_> Hello, I wonder if there capes rj45 for beaglebone black
