**** BEGIN LOGGING AT Thu Jun 11 02:59:59 2015
Jun 11 06:25:35 <jeevan> i would like to develop the sdcard driver in linux with SPI interface from scratch, could some once guide me on this
Jun 11 06:28:25 <thurgood_> maybe start with an existing 12c driver and replace the reads reads/writes?
Jun 11 06:29:07 <thurgood_> any particular reason you want to do it from scratch?
Jun 11 06:33:13 <jeevan> hi thurgood thanks for reply, it is for learning only.
Jun 11 06:36:11 <jeevan> when i get the kernel source from kernel.org, does it contains all drivers code for beagleboard ?
Jun 11 06:41:55 <jeevan> hi can some one answer
Jun 11 06:43:24 <Abhishek_> jeevan: clone http://github.com/beagleboard/linux
Jun 11 06:44:54 <jeevan> :Abhishek, thats right but my question is when i get the kernel source from www.kernel.org, does it contain all peripherals drivers source ?
Jun 11 06:45:09 <jeevan> for beagleboard
Jun 11 07:00:14 <Abhishek_> jeevan: You should be able to boot up the system, but some things may not work as expected.
Jun 11 07:04:52 <thurgood_> there are probably some patches that have not made it into mainline yet... I don't follow it that closely these days
Jun 11 07:09:37 <tbr> thurgood_: for 4.0 the patchset was very small last time I checked
Jun 11 07:26:48 <Abhishek_> yup, a day will not be far when they will run off stock kernels without having to maintain vendor trees
Jun 11 10:17:10 <pratik> hello
Jun 11 10:18:12 <pratik> can beagle board support parallel camera interface.?
Jun 11 11:24:54 <citylight2> is there anything inspiring someone used the PRU for?
Jun 11 11:26:16 <SpeedEvil> Define inspiring.
Jun 11 11:26:28 <SpeedEvil> There is a limited linuxcnc port for it - which is quite cool
Jun 11 11:28:13 <av500> and many led blink projects
Jun 11 11:31:33 <tbr> and banging bits real fast
Jun 11 11:34:25 <SpeedEvil> Or even doing parallel camera interfaces
Jun 11 11:38:43 <citylight2> cnc I know about, it is cool. parallel camera? where?
Jun 11 11:39:27 <citylight2> I am interested in any RF DSP , but also VOIP is interesting
Jun 11 11:40:09 <citylight2> well, PRU can even compress decompress voice...
Jun 11 11:46:55 <av500> PRU aint a DSP
Jun 11 11:47:47 <panto> av500, sure
Jun 11 11:48:04 <panto> but 200MHz is plenty for basic narrowband codec work
Jun 11 11:48:04 <woglinde> hoi panto
Jun 11 11:48:06 <panto> hi woglinde
Jun 11 11:48:20 <panto> as long as the code fit :)
Jun 11 11:49:08 <av500> true
Jun 11 11:49:21 <av500> it also helps to not wear out the main CPU
Jun 11 11:49:27 <av500> keep the gates fresh
Jun 11 11:50:03 <SpeedEvil> citylight2: I was meaning in principle
Jun 11 11:50:29 <SpeedEvil> panto: Did you know that voice narrowband coding was first done in WWII?
Jun 11 11:50:35 <SpeedEvil> Using many tons of hardware.
Jun 11 11:51:06 <SpeedEvil> http://en.wikipedia.org/wiki/SIGSALY
Jun 11 11:51:12 <panto> people shooting at you tends to focus the mind
Jun 11 11:51:29 <SpeedEvil> It also links to the patent - it looks quite interestingly implementable very simply today
Jun 11 11:52:07 <KotH> SpeedEvil: the first gps receivers were boxes close to 100l size and 10-15kg
Jun 11 11:52:18 <SpeedEvil> yeah.
Jun 11 11:52:28 <KotH> SpeedEvil: ok.. actually, these were the first portable gps receivers
Jun 11 11:52:29 <SpeedEvil> Now you could do it on _drumroll_ a PRU
Jun 11 11:52:41 <KotH> the first gps receivers were mounted on ships and couldnt be moved
Jun 11 11:52:44 <SpeedEvil> http://www.maximintegrated.com/en/products/comms/wireless-rf/MAX2769.html
Jun 11 11:52:51 <SpeedEvil> 18mbps bitstream
Jun 11 11:53:04 <KotH> SpeedEvil: nope, a PRU does not have enough processing power for a complete gps receiver
Jun 11 11:53:06 <SpeedEvil> Encoding the whole GPS spectrum, so you can do it in software
Jun 11 11:53:09 <KotH> SpeedEvil: not even single channel
Jun 11 11:53:13 <SpeedEvil> KotH: It does.
Jun 11 11:53:16 <KotH> SpeedEvil: it does not
Jun 11 11:53:44 <KotH> SpeedEvil: i have a gps implementation in software, i know how much processing it takes
Jun 11 11:54:06 <SpeedEvil> KotH: I've actually gotten to the assembly timing stage on a STM32 based one - it does. It's complex, and you willl need to do a fair amount of the heavy lifting on the BBB
Jun 11 11:54:29 <SpeedEvil> the PRU can do important bits of it though - deserialising and some correlation
Jun 11 11:54:42 <SpeedEvil> and all the hard-realtime stuff
Jun 11 11:55:32 <KotH> yes, if you split the problem up and only do 2-3 correclators on the pru with 1bit adc, then it might be enough.. barely
Jun 11 11:56:02 <KotH> also 2Msps max
Jun 11 11:58:40 * SpeedEvil checks.
Jun 11 11:58:46 <SpeedEvil> Aww - the PRU has no countones
Jun 11 12:47:11 <Abhishek_> the PRUs can also turn your BeagleBone Black into a 100Msps, 320 MB Logic analyzer ;)
Jun 11 12:49:04 <citylight2> Abnisek: wow, how? where?
Jun 11 12:51:15 <Abhishek_> beaglelogic.net
Jun 11 13:05:13 <gurki> Abhishek_: is there a usefull gui for that?
Jun 11 13:05:32 <gurki> just curious as the fancy part about las tends to be a gui one is actually able to work with
Jun 11 13:05:45 <gurki> (feel free to throw a generic gui at me that can read this dumps ...)
Jun 11 13:05:54 <gurki> theese*
Jun 11 13:06:02 <Abhishek_> gurki: There's a web interface but at the moment it isn't very fancy
Jun 11 13:06:28 <Abhishek_> you can copy the dumps and view them on their PC using PulseView
Jun 11 13:06:54 <gurki> got several bbs around i use for different projects ... might just give it a try
Jun 11 13:07:01 <gurki> getting to my salea clones limits
Jun 11 13:07:44 <gurki> pulseview actually looks usable ..
Jun 11 13:08:20 <gurki> shouldnt be too much of a hassle to control that bbb over lan. its just one line of ssh ^
Jun 11 13:08:34 <gurki> and grab that dump with scp
Jun 11 13:08:35 <gurki> hum.
Jun 11 13:08:50 <gurki> guess ill give it a shot next time i got some spare time
Jun 11 13:11:45 <Abhishek_> gurki: Let me know when you do, I should be around.
Jun 11 13:12:39 <gurki> Abhishek_: will do :)
Jun 11 13:34:16 <citylight2> According to my google searches , I understood I need to use a special hostapd fork to run an access point on my 8188eu
Jun 11 13:34:37 <citylight2> but rcn-ee cliamed I should be able to use the mainline hostapd
Jun 11 13:34:47 <citylight2> does anyone here use the 8188eu ?
Jun 11 15:53:42 <mistawright> hi guys i am using debian and wanted to build a kernel module. Where should the simlink for build point to?
Jun 11 15:57:19 <woglinde> the kernel headers?
Jun 11 15:57:26 <woglinde> which are proably not there?
Jun 11 15:57:47 <rcn-ee> mistawright, /lib/modules/`uname -r`/build/
Jun 11 15:57:57 <rcn-ee> after: apt-get install linux-headers-`uname -r`
Jun 11 15:58:28 <mistawright> ive installed the headers for the latest kernel but when trying to build the rtl8812au driver i get this error:  make[1]: *** /lib/modules/4.0.4-rt1-bone4/build: No such file or directory.  Stop.
Jun 11 16:00:08 <rcn-ee> mistawright, "latest" is not the same as "headers for `uname -r`"... make sure they match..
Jun 11 16:03:52 <mistawright> I had installed the latest linux-image 4.10 bone 7 but running uname -a shows bone 4
Jun 11 16:04:02 <mistawright> installing again and about to reboot to double check
Jun 11 16:12:03 <mistawright> that seems to have done the trick. kernel module built fine
Jun 11 16:15:22 <mistawright> so with the latest kernel am I able to tell which overlay is loaded by catting a file? I realize that there is no bonecapemgr directory under /sys/device/
Jun 11 16:26:48 <rcn-ee> mistawright, 'cating' doesn't work in 4.1 ... yet..
Jun 11 16:27:35 <rcn-ee> you will find /sys/devices/platform/bone_capemgr/slots
Jun 11 17:49:36 <Abhishek_> rcn-ee: My created kernel deb package takes forever to install on the BeagleBone, all files copied are prefixed with .dpkg-new .
Jun 11 17:49:44 <Abhishek_> *postfixed
Jun 11 17:51:19 <rcn-ee> Abhishek_, mine take a while too, 4.1.x is big..
Jun 11 18:04:23 <Abhishek_> rcn-ee: How much time approx?
Jun 11 18:08:33 <rcn-ee> 2-3 minutes..
Jun 11 18:09:50 <Abhishek_> rcn-ee: Mine gets stuck unpacking > 30 mins, had to abort it
Jun 11 18:10:36 <Abhishek_> not sure if that's expected
Jun 11 18:13:44 <rcn-ee> nope... did you enable debug info?
Jun 11 18:20:48 <whine> anyone with experience with qemu  / wine(x86)  ?  trying to get a windows  .exe (made for Windows 98) to run on BBB (debian)

Jun 11 18:59:09 <stt_michael> erm. ok.
Jun 11 19:07:27 <durak> Hi, I am having trouble setting up my beaglebone. When I plug in the USB to connect it to my windows 7 computer, it says USB device not recognized. I have installed the drivers and restarted my computer though.
Jun 11 19:11:46 <durak> ??
Jun 11 19:14:59 <durak> ?
Jun 11 19:16:20 <durak> anyone have any idea why my beagleboard won't show up as a usb drive?
Jun 11 19:20:33 <durak> anyone?
Jun 11 19:22:50 <stt_michael> Windows.
Jun 11 19:23:04 <mistawright> lol
Jun 11 19:23:04 <durak> ...
Jun 11 19:23:14 <mistawright> what does it show up as in the device manager?
Jun 11 19:23:37 <durak> unknown device.
Jun 11 19:23:39 <mistawright> maybe you should go to the beagleboard website and find drivers if your computer can't find it
Jun 11 19:24:03 <durak> I downloaded the drivers already, restarted computer. The lights are all flashing like they should, but it doesn't recognize it.
Jun 11 19:24:26 <mistawright> what version of windows
Jun 11 19:24:32 <durak> 7
Jun 11 19:24:50 <mistawright> thats your problem, wipe that and install gentoo linux. thank me later
Jun 11 19:25:02 <mistawright> not sure what the cause is but its driver related
Jun 11 19:25:12 <mistawright> why are you not just sshing into it?
Jun 11 19:25:57 <mistawright> connect it to your router and just ssh into it. problem solved, unless that is the reason for the usb connection
Jun 11 19:27:10 <durak> I guess I will try that. Still would be good to know why this isn't working...
Jun 11 19:28:03 <mistawright> its not the beaglebone, its windows at this point. have you tried different ports? what does it even detect the device as
Jun 11 19:28:35 <mistawright> https://learn.adafruit.com/ssh-to-beaglebone-black-over-usb/installing-drivers-windows
Jun 11 19:28:40 <mistawright> see if that helps
Jun 11 19:28:45 <durak> I've tried different usb ports with the same issue.
Jun 11 19:29:25 <durak> I have done that.
Jun 11 19:29:42 <durak> For some reason it's not associating the drivers with the beaglebone
Jun 11 19:29:58 <mistawright> was there another driver already installed if so uninstall and delete it
Jun 11 19:30:13 <mistawright> can do that through the device manager
Jun 11 19:30:31 <rcn-ee> durak, grab the latest, just encase you had an old version: https://github.com/beagleboard/beaglebone-getting-started/tree/master/Drivers/Windows
Jun 11 19:31:31 <mistawright> but like my earlier comment, it would be easier to just use linux on your dekstop ;)
Jun 11 19:33:09 <durak> I unfortunately don't have that option. Thanks for the help anways, I'll try to figure this out
Jun 11 19:36:15 <Okular> what's up durak
Jun 11 20:20:28 <mistawright> havent used my beaglebone black in a while because i thought it wasnt reading micrsod cards. Finagled with the pins on the microsd card reader reading now. weird
Jun 11 20:23:11 <myself> score one for finagling!
Jun 11 20:29:15 <citylight2> hi rcn-ee, ok so I can't run hostapd on the 8188eu
Jun 11 20:29:27 <citylight2> i mean the mainline hostapd
Jun 11 20:32:23 <citylight2> oh its TP-Link TL-WN725N V2
Jun 11 20:36:16 <veremit> o,o thought you fixed that citylight2 :p
Jun 11 20:36:43 <citylight2> rcn asked me to try the mainline hostapd, so I tried and failed
Jun 11 20:37:04 <veremit> hehe you should patch the mainline hostapd :P
Jun 11 20:37:26 <veremit> but I suspect the issue arises from the 8188 driver
Jun 11 20:38:23 <rcn-ee> 725? i got the WN723N. ;)
Jun 11 20:38:46 <citylight2> my is 0bda:8179
Jun 11 20:39:06 <rcn-ee> 0bda:8179
Jun 11 20:39:25 <citylight2> so i was wrong
Jun 11 20:39:38 <citylight2> I got the same adaptor as you
Jun 11 20:39:41 <rcn-ee> or tp-link has the same chip in two cases. ;)
Jun 11 20:39:46 <citylight2> can you run an access point?
Jun 11 20:40:21 <rcn-ee> going to give it a shot
Jun 11 20:40:59 <citylight2> o you are correct its tl-wn723n
Jun 11 20:41:37 <citylight2> so i assumed that its possible to run an access point on this adapor
Jun 11 20:41:56 <citylight2> and was looking to adapt my program to work with it
Jun 11 20:42:10 <citylight2> cwvw, and another name is welcome
Jun 11 20:50:59 <veremit> citylight2 .. good luck on the quest for a good name :)
Jun 11 20:52:56 <rcn-ee> citylight2, refresh this page a few times and steal a name: tiffzhang.com/startup/ ;0
Jun 11 20:54:04 <veremit> lolol rcn-ee
Jun 11 21:03:42 <rcn-ee> citylight2, nothing but: Starting advanced IEEE 802.11 management: hostapd failed!
Jun 11 21:05:51 <citylight2> use hostapd -d -t /etc/hostapd/hostapd.conf
Jun 11 21:06:41 <rcn-ee> Could not read interface <wlan0> flags: No such device
Jun 11 21:06:48 <rcn-ee> hum, must use a different indentifer?
Jun 11 21:08:31 <citylight2> ip link show?
Jun 11 21:11:05 <rcn-ee> wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
Jun 11 21:12:19 <citylight2> so you need driver_rtl.h
Jun 11 21:12:34 <citylight2> sorry: https://github.com/jenssegers/RTL8188-hostapd
Jun 11 21:12:44 <rcn-ee> even for mainline's ap driver?
Jun 11 21:13:27 <rcn-ee> (kernel mainline)
Jun 11 21:13:35 <veremit> rcn-ee .. depends how ap-mode is implemented in driver I suspect
Jun 11 21:14:01 <rcn-ee> of course, it's only been two kernel releases, it's probally mostly just a cleaned up rtl driver at this point..
Jun 11 21:14:12 <veremit> I know the broadcom's have some strange jazz .. hence Cruz's effort on the wand
Jun 11 21:14:58 <veremit> I'm not sure anyone's re-written the rtl drivers properly yet .. remember that 8192cu card I had issues with!?
Jun 11 21:15:11 <veremit> works ok with the proprietary code
Jun 11 21:15:27 <veremit> not proprietary .. you know .. vendor source
Jun 11 21:16:06 <rcn-ee> oh wait, line 11: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/staging/rtl8188eu/TODO#n11
Jun 11 21:16:09 <rcn-ee> .... ;)
Jun 11 21:16:57 <rcn-ee> so it's still stuck using rtl's custom hostapd..
Jun 11 21:17:20 <citylight2> ok so we are both in the same place
Jun 11 21:17:48 <rcn-ee> ...takes a look at wireless mainline list... ;)
Jun 11 21:18:18 <veremit> time for some major coding, rcn-ee ?! ;P
Jun 11 21:19:15 <rcn-ee> seeing what i can steal for 4.2.0-rc1 merge..
Jun 11 21:22:33 <citylight2> this has a better antena then the famous edimax 8192cu
Jun 11 21:22:59 <veremit> citylight2 .. this card is pre-mounted on an Allwinner A13 board.
Jun 11 21:23:52 <veremit> citylight2 .. https://www.olimex.com/Products/OLinuXino/A13/A13-OLinuXino-WIFI/open-source-hardware for reference :)
Jun 11 21:24:24 <veremit> Although .. why do they say .. hrm ..
Jun 11 21:25:29 <veremit> I'm *sure* that was using the 8192 driver for some reason ..
Jun 11 21:26:23 <rcn-ee> just more cleanups for v4.2-rc0... so nothing really useful to..
Jun 11 21:29:18 <citylight2> can I use the edimax 8192cu with the mainline hostapd?
Jun 11 21:30:11 <veremit> citylight2 .. I dunno whether the 8192 module has been fully fixed up in mainline yet
Jun 11 21:33:17 <citylight2> the only issue with the atheros based usb adaptor is the size
Jun 11 21:33:24 <citylight2> its too big
Jun 11 21:33:25 <veremit> used to be the bane of all those mini-wifi cards that were popular for *cough*pi
Jun 11 21:35:55 <rcn-ee> if only the pi had musb based usb... then no one would have bought those. ;)
Jun 11 21:36:58 <rcn-ee> 8192's still the cheapest pices of crap... stripped two down to the guts, exactly the same oem, one worked, other was random..
Jun 11 21:44:49 <veremit> *nod*
