Nov 12 03:58:29 <geekswine> hii..i have workde on arduino and atmega 256.. i have gone through the BBB manual...since i am newbie to it i am not getting that from which project i should start
Nov 12 03:58:39 <geekswine> can anyone help me plss ??
Nov 12 04:01:35 <geekswine> i will be geeting BBB in 1 month so till then, how can i contribute to a project...if there is any theoritical or simulation work...where i can work ??
Nov 12 04:04:19 <geekswine> i have gone through many projects but not getting that which project will be suitable for me as not made any library except lcd jhd162a, which i made for atmega 16a
Nov 12 05:17:44 <Winston> Hi
Nov 12 05:20:23 <Guest63491> We built a CPU card based on AM3359ZCZD72 referring the Beaglebone black schematics. We have not added any new circuits in it. I need to say it is an exact replica of Beaglebone black only the form-factor is changed. We are seeing the following problem when we tried powering up the CPU card: •         The voltage at pins 7 & 8 of TPS65217CRSL have a 5V with a ripple of 0.5V pulsing at the rate of 100mS •         The Voltage a
Nov 12 05:21:11 <Guest63491> •         The Voltage at the Pin 3, VLDO1 is appearing as a square wave at the rate of 100mS instead of pure DC.
Nov 12 05:24:04 <Guest63491> Could u please help me in this regard
Nov 12 05:56:41 <Guest63491> any reply for my query above

Nov 12 07:27:01 <kenrestivo> *cough* capacitor *cough*
Nov 12 07:27:23 <KotH> *cough* flux capacitor *cough*
Nov 12 07:28:15 <KotH> and it's probably bad layout coupled with inaproriate power supply
Nov 12 07:43:44 <quickhelp> Hey guys... any reason screen /dev/ttyO4 115200 would completely crash the system?
Nov 12 07:47:36 <KotH> pinmux wrong?
Nov 12 07:50:14 <_av500_> KotH: :)
Nov 12 07:50:22 <_av500_> quickhelp: what system?
Nov 12 07:50:31 <quickhelp> beaglebone black
Nov 12 07:50:45 <quickhelp> uname -r .... 3.8.13-bone67
Nov 12 07:50:47 <_av500_> so you run screen on the BBB?
Nov 12 07:51:00 <quickhelp> i have an arduino configured to run at 115200
Nov 12 07:51:03 <_av500_> ah
Nov 12 07:51:06 <quickhelp> i have enable UART4
Nov 12 07:51:10 <_av500_> ok
Nov 12 07:51:14 <quickhelp> via echo > BB-UART4 > sys...blah
Nov 12 07:51:14 <_av500_> and it crashes always?
Nov 12 07:51:18 <quickhelp> yup
Nov 12 07:51:20 <quickhelp> screen crashes
Nov 12 07:51:24 <quickhelp> using python serial crashes
Nov 12 07:51:38 <quickhelp> i just updated the kernel today
Nov 12 07:52:30 <_av500_> debain?
Nov 12 07:52:35 <quickhelp> yes
Nov 12 07:52:55 <_av500_> hmm, that has no capemanager
Nov 12 07:53:01 <_av500_> how do you enable uart4?
Nov 12 07:53:27 <quickhelp> echo BB-UART4 > /sys/devices/bone_capemgr.9/slots
Nov 12 07:53:35 <KotH> 08:52 <@_av500_> hmm, that has no capemanager
Nov 12 07:53:52 <_av500_> or does it?
Nov 12 07:54:02 <KotH> _av500_: either one of you is wrong :)
Nov 12 07:54:05 <_av500_> quickhelp: do you have that sys file?
Nov 12 07:54:07 <quickhelp> Debian GNU/Linux 7  BeagleBoard.org BeagleBone Debian Image 2014-04-23  Support/FAQ: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian
Nov 12 07:54:08 <quickhelp> on login
Nov 12 07:54:27 <KotH> quickhelp: neither one of us is running debian on the BBB
Nov 12 07:54:38 <_av500_> quickhelp: do you have that sys file?
Nov 12 07:54:49 <_av500_> ls /sys/devices/bone_capemgr.9
Nov 12 07:54:56 <quickhelp> yes
Nov 12 07:55:41 <quickhelp> so it was working a few hours ago
Nov 12 07:55:55 <quickhelp> now I can't touch it with screen, cat, or python without locking up the whole system
Nov 12 07:56:04 <_av500_> ah
Nov 12 07:56:30 <quickhelp> i can still enable it and see it in /dev
Nov 12 07:56:36 <KotH> did you try to turn it off and on again?
Nov 12 07:56:44 <KotH> (yes, seriously)
Nov 12 07:56:44 <quickhelp> ?
Nov 12 07:57:00 <quickhelp> well the BB gets powered on and off every crash
Nov 12 07:57:02 <quickhelp> so yes?
Nov 12 07:57:07 <KotH> no
Nov 12 07:57:17 <KotH> unpower completely, wait 5min, power up again
Nov 12 07:57:27 <KotH> maybe some hw is in a weird state and needs a hard reset
Nov 12 07:57:42 <quickhelp> k
Nov 12 07:57:45 <quickhelp> so next question
Nov 12 07:58:00 <quickhelp> 2011 macbook pro now... screen /dev/tty.usb 115200
Nov 12 07:58:04 <quickhelp> locks the whole system up
Nov 12 07:58:23 <quickhelp> well... only the keyboard
Nov 12 07:58:24 <KotH> you seem to have some bad karma
Nov 12 07:58:30 <quickhelp> i can ssh into it and reboot it
Nov 12 07:58:31 <quickhelp> or hard reboot
Nov 12 07:58:50 <quickhelp> just curious if anyone else has ran into this many issues with serial interfaces
Nov 12 07:59:02 <KotH> no, serial usualy works fine here
Nov 12 07:59:18 <quickhelp> any system logs i can check that would tell me anything?
Nov 12 07:59:21 <KotH> but i only use it with linux anyways... windows is too buggy and i'm not rich enough to buy apple stuff
Nov 12 07:59:47 * KotH has no idea how to debug macos
Nov 12 07:59:51 <quickhelp> strangely enough if i access it within a debian VM I have no issues
Nov 12 08:00:06 <quickhelp> i meant on the BB ... any good logs to check in debian?
Nov 12 08:00:52 <quickhelp> and KoTH the system was down for ~30 minutes last time no power and had no change
Nov 12 08:00:57 <KotH> hmm?
Nov 12 08:01:13 <KotH> you mean running screen on your macos locks up your bbb?
Nov 12 08:01:24 <quickhelp> no
Nov 12 08:01:39 <quickhelp> serial devices to BB ... screen on BB
Nov 12 08:02:15 <KotH> well, if there is a hard lock up, and you dont get anything on the debug console, then you are out of luck
Nov 12 08:02:27 <KotH> you wont have any log files either
Nov 12 08:02:42 <KotH> all you can do is try a newer kernel
Nov 12 08:02:53 <KotH> but be aware that there is no capemanager in mainline
Nov 12 08:04:08 <_av500_> but its still doable
Nov 12 08:04:16 <_av500_> google knows how to
Nov 12 08:04:53 <quickhelp> so the latest debian image for BB has no cpaemanager?
Nov 12 08:04:59 <quickhelp> (just clarifying)
Nov 12 08:05:16 * KotH has no idea
Nov 12 08:05:25 * KotH does not run debian on the BBB
Nov 12 08:05:28 <quickhelp> what is mainline
Nov 12 08:05:33 <quickhelp> angstrom?
Nov 12 08:05:40 <KotH> mainline = linus kernel
Nov 12 08:06:57 <quickhelp> so no ideas otherwise?
Nov 12 08:09:34 <KotH> if the hardware itself is fine, it shouldnt lock up when you run something on the serial port
Nov 12 08:09:48 <KotH> all i can think of is either a bug in the kernel or wrong pinmuxing
Nov 12 08:10:00 <KotH> while the former is less likely
Nov 12 08:10:25 <KotH> alternatively you can ask woglinde, he knows "things"
Nov 12 08:12:16 <quickhelp> woglinde > I have a BBB that I have a serial device connected to UART4. On running 'screen /dev/ttyO4 115200' the system receives shortly then completely locks up
Nov 12 08:12:21 <quickhelp> any ideas?
Nov 12 08:16:52 <_av500_> I would install latest debian
Nov 12 08:16:58 <_av500_> from the BBB home page
Nov 12 08:17:03 <_av500_> enable UART and try agian
Nov 12 08:22:31 <quickhelp> necessary to reflash?
Nov 12 08:23:53 <woglinde> quickhelp uhm sounds like a kernel or hw error
Nov 12 08:24:04 <woglinde> or pinmux is wrong somehow
Nov 12 08:25:40 <quickhelp> i enable using the capemgr
Nov 12 08:26:20 <quickhelp> echo BB-UART4 > /sys/devices/bone_capemgr.9/slots
Nov 12 08:26:34 <quickhelp> stty -F /dev/ttyO4 115200
Nov 12 08:26:46 <quickhelp> then screen /dev/ttyO4 115200 and crash
Nov 12 08:30:26 <quickhelp> thanks all

Nov 12 08:45:59 <KotH> Guest63491: repeating the same question over and over will not get any more help
Nov 12 08:46:05 <KotH> Guest63491: you just annoy people
Nov 12 08:46:12 <KotH> Guest63491: read what has been written
Nov 12 08:46:19 <_av500_> also few people here are down to the hardware
Nov 12 08:46:22 <KotH> Guest63491: if you need help, hire someone who knows how to do that stuff
Nov 12 08:46:37 <KotH> Guest63491: i can recommend www.aotag.ch, they know how to do this kind of stuff
Nov 12 09:59:26 <steven__> hello all, i have a usb device that upon booting is found but not supported.  Kernel 3.14.  The driver for the device is present, is this an issue with the musb-hdrc?
Nov 12 10:00:13 <_av500_> what device?
Nov 12 10:00:13 <_av500_> dmesg log?

Nov 12 10:02:14 <_av500_> device v110a p1613 is not supported
Nov 12 10:02:29 <_av500_> hmm
Nov 12 10:02:56 <steven__> yea i am at a lost as how to add support for the device
Nov 12 10:03:17 <_av500_> is there linux support for it?
Nov 12 10:03:21 <_av500_> in general?
Nov 12 10:03:46 <steven__> some.  on another machine kernel 3.17 I have had it work.
Nov 12 10:04:52 <steven__> the module is present in the kernel build, so I hoped it would be supported.  I was wondering if it was an issue with device being a sort of hub.

Nov 12 11:06:52 * KotH uses the other lifestream
Nov 12 11:08:06 <tbr> the spice must flow!
Nov 12 11:08:21 * tbr walks to the bus stop (without rhythm)
Nov 12 11:08:36 <KotH> +1
Nov 12 14:10:19 <uphill> If you set the pins in the dts to the pr1_pru1_pru_r30_0 mode, can i control and read them directly from the prus?
Nov 12 14:10:40 <uphill> from r30 bit 0 then, right?
Nov 12 14:13:48 <uphill> I don't understand what people are doing with the GPIO offsets in all the examples
Nov 12 14:49:06 <pingo> Is there a guide on how to remove all unneeded services on beaglebone black debian image?
Nov 12 14:51:58 <agmlego> no more so than for any given debian, i would think.
Nov 12 15:13:45 <chnyc_> Hi Anuj. Charles here. So...userspace-arduino.
Nov 12 15:13:58 <chnyc_> And thanks for helping out.
Nov 12 15:40:36 <uphill> Answer to myself: r30 and r31 are the way to go
Nov 12 15:53:36 <KotH> uphill: would you mind to stick around and answer pru related questions?
Nov 12 15:53:48 <KotH> uphill: we get those a lot and none of the regulars has used the pru so far
Nov 12 15:54:35 <uphill> KotH: If I can answer them, Ill be here
Nov 12 18:16:06 <geekswine> gone through BBB..can anyone suggest me some project or bug in a project from where I can start and learn more about it ??
Nov 12 18:19:55 <Nacho__> hi,  can you tell me why the board isnt sold for south america??
Nov 12 18:20:41 <agmlego> Probably export reasons.
Nov 12 19:17:00 <_av500_> its sold where distributors sell it
Nov 12 19:48:40 <vagrantc> anyone have a /proc/cpuinfo from a beaglebone black running a recent (3.16+) kernel?
Nov 12 19:57:30 <sph_> Edimax EW-7811Un usb wifi adapter is not working with beaglebone black rev c. Please guide how to make it work ?
Nov 12 20:00:12 <woglinde> lol
Nov 12 20:00:47 <woglinde> looks like sph_ has solved it himself
