Jul 21 10:13:43 <ebadawy> jkridner: ping
Jul 21 12:59:31 <arianepaola> vvu: ping
Jul 21 13:11:18 <DiegoTc> _av500_ , jkridner: just letting you know ebadawy will finish to publish his report tomorrow. the section to work for this week
Jul 21 13:11:32 <DiegoTc> I want to do some testing and check his agenda with missing dates
Jul 21 13:12:00 <jkridner> ebadawy: what's up? very busy day today, so I might not be very responsive.
Jul 21 13:12:06 <DiegoTc> I and unfortunately we're 8 hours of difference, so it's impossible a meeting a 2am his hour
Jul 21 13:12:25 <DiegoTc> jkridner: talking with him right now
Jul 21 13:12:28 <DiegoTc> about the BBUI
Jul 21 13:12:52 <DiegoTc> he's going to work right now on shaping it
Jul 21 13:12:57 <DiegoTc> to the bonecard size
Jul 21 13:13:58 <ebadawy> jkridner: was talking with DiegoTc about what I did with BBUI and what I sould have done
Jul 21 13:14:39 <ebadawy> as you said that I can foucs on adding BBUI as bonecard rather than migrating its functionality
Jul 21 13:15:33 <ebadawy> which I didn't understand that it should take the bonecard shape!
Jul 21 13:16:15 <ebadawy> and because of that I think that I am behind the schedule now :(
Jul 21 13:24:11 <Abhishek__> apaar: How's it going with the benchmarking?
Jul 21 13:26:51 <arianepaola> vvu moto-timo jkridner I will have access to a Mac at home, from this Friday on. a friend of mine from uni is going on vacation, leaving her mac mini behind for a month or so :-)
Jul 21 13:27:31 <arianepaola> vvu was pinging you to check regarding Mac work
Jul 21 13:39:21 <Abhishek__> neemo: not sure if including Doxygen generated HTML files on GitHub is a good idea.
Jul 21 14:00:25 <arianepaola> neemo: if you only include the Doxyfile.cfg, then it is possible to generate the documentation locally :-)
Jul 21 14:03:47 <jkridner> arianepaola: great
Jul 21 15:40:48 <neemo> Abhishek__: fixed
Jul 21 15:41:09 <neemo> Abhishek__: Was a bit to liberal with the adds, without the proper .gitignores in place
Jul 21 15:41:41 <neemo> Abhishek__: also made the make file behave, so it'll rebuild the docs with a make doxy
Jul 21 15:46:07 <neemo> nerdboy: alexanderhiam: available?
Jul 21 16:31:37 <nerdboy> he should be up before me i think...
Jul 21 16:35:59 <neemo> dunno, long day yesterday?
Jul 21 16:36:34 <neemo> but anyway, both or any of you two is fine
Jul 21 16:36:42 <neemo> also good mid'day
Jul 21 16:37:51 <neemo> nerdboy: open to go over a couple of things while we're both here?
Jul 21 16:39:27 <nerdboy> did you push anything yet?
Jul 21 16:39:43 <neemo> the input output LKM
Jul 21 16:39:49 <neemo> most basic form
Jul 21 16:40:10 <neemo> and the API header is going up
Jul 21 16:40:14 <neemo> is up*
Jul 21 16:40:39 <neemo> it's going forward, but I'd say it's half way there
Jul 21 16:41:21 <neemo> take a look at it if you can and especially at the todo tags, those are the design choices that are kinda bugging me
Jul 21 16:41:40 <neemo> after a pull, a "make doxy" should build all the documentation in /docs
Jul 21 16:42:39 <nerdboy> looks good so far, but i just woke up...
Jul 21 16:42:48 <neemo> feel free to bash me at the things that make no sense, I'm in doubt at a couple of places, so guidelines welcome
Jul 21 16:43:01 <neemo> hah, alright, no rush
Jul 21 16:43:26 <neemo> I'm going to be doing a bit more on the API, a couple more functions to add (parameter processing and stuff)
Jul 21 16:43:44 <neemo> but for anything further I'll need to fix stuff on the LKM stuff
Jul 21 16:44:08 <neemo> I've uploaded the most basic input->output sysfs device LKM I could come up with
Jul 21 16:44:15 <nerdboy> do what you can and hang around
Jul 21 16:44:37 <nerdboy> not sure what alexanderhiam has going schedule-wise
Jul 21 16:45:24 <neemo> but I need to enable float support (gcc wasn't happy with my %f's) and either an additional control to start the processing or an interupt based processing (eg. when you write to the input file) would make sense
Jul 21 16:45:54 <neemo> nerdboy: any idea on the float support for kernel code on ARM?
Jul 21 16:46:03 <nerdboy> i'm mostly okay till my regular meeting at 3, but i might have a short task first...
Jul 21 16:46:32 <neemo> nerdboy: yeah, I'll be hanging around, though I'll go get some sleep in an hour or so
Jul 21 16:46:54 <nerdboy> lemme pull and i'll look at your cflags
Jul 21 16:47:13 <nerdboy> sleep with irc connected?
Jul 21 16:47:25 <neemo> the lkm is in the inoutlkm folder
Jul 21 16:47:46 <neemo> super basic, I adapted most of the code from the stuff I read at derekmolloy's website
Jul 21 16:47:50 <neemo> seems to work though
Jul 21 16:47:54 <neemo> yeah,
Jul 21 16:48:09 <neemo> If I go get some shuteye, IRC will stay on
Jul 21 16:48:37 <neemo> I check the log anyway, since my connection tends to break sometimes, so rarely miss stuff on this channel :)
Jul 21 17:02:56 <neemo> nerdboy: specifically, when using inoutlkm with %f inputs and outputs, I get warnings for unsupported floating point operations
Jul 21 17:03:04 <neemo> eg. WARNING: "__aeabi_fsub" etc.
Jul 21 17:03:18 <neemo> and obviously, insmod won't load my module
Jul 21 17:04:54 <nerdboy> okay, i'll take a look in few minutes
Jul 21 17:08:17 <neemo> k thx
Jul 21 17:26:15 <moto-timo> arianepaola: good to hear about the Mac... that will help :)
Jul 21 17:26:50 <DiegoTc> _av500_:  Ankur and Ehab show their status last week (http://logs.nslu2-linux.org/livelogs/beagle-gsoc/beagle-gsoc.20150716.txt)
Jul 21 17:28:05 * nerdboy still has a bunch of ppc mac stuff in need of a good home...
Jul 21 17:28:45 <nerdboy> think ibook has "latest" 3.6 gnome on it
Jul 21 17:32:52 <neemo> anybody compiled a kernel module with float support on the BBB?
Jul 21 17:35:57 <_av500_> DiegoTc: oops
Jul 21 17:36:12 <nerdboy> sleep 216000 first
Jul 21 17:36:42 <_av500_> DiegoTc: I guess we had everybody once
Jul 21 17:36:50 <_av500_> so tomorrow will volunteers forst
Jul 21 17:36:52 <_av500_> first
Jul 21 17:38:57 <DiegoTc> _av500_: corect
Jul 21 17:38:59 <DiegoTc> reading logs: <jkridner> _av500_: did I forget to get students on the hook for next week?
Jul 21 17:39:25 <jkridner> DiegoTc: _av500_ sent notices.
Jul 21 17:39:50 <_av500_> jkridner: but wrong ones
Jul 21 17:40:00 <_av500_> jkridner: one cycle is complete, so we start a new one
Jul 21 17:40:13 <_av500_> everybody should be able to report on status
Jul 21 17:40:18 <_av500_> so we do it adhoc
Jul 21 17:51:11 <neemo> nerdboy: on the LKM, when I switch to %f for inputs and outputs instead of %d, the compiler gives me a some nice rubbing about that
Jul 21 17:51:39 <neemo> nerdboy: tries adding
Jul 21 17:51:39 <neemo> ccflags-y := -mhard-float
Jul 21 17:52:26 <neemo> tried adding that flag for the LKM, and make gives me an awkward gcc: error: -msoft-float and -mhard_float may not be used together
Jul 21 17:53:01 <neemo> nerdboy: tried using flags from this blog -> http://www.eliteraspberries.com/blog/2013/09/cflags-for-numerical-computing-on-the-beaglebone-black.html and well...
Jul 21 17:53:30 <neemo> I get a string in the place I should be getting floats from the sysfs device entries
Jul 21 17:53:52 <nerdboy> i'll fix your makefile if you get some rest
Jul 21 17:54:30 <nerdboy> after that we'll get with alexanderhiam
Jul 21 17:54:41 <neemo> ha, alrighty
Jul 21 17:54:47 <neemo> deal
Jul 21 17:55:36 <neemo> the current makefile and inoutlkm is working for ints, so switch those to %f when you're testing
Jul 21 17:58:14 <ankur> hi Abhishek__
Jul 21 18:13:48 <neemo> alright, good night guys
Jul 21 18:14:22 <neemo> nerdboy: alexanderhiam see you back here in around 6 hours
Jul 21 18:14:32 <neemo> also report day
Jul 21 18:17:00 <ankur> hi guys, can we use CAN to communicate between two beagles without using any cape?
Jul 21 18:23:28 <moto-timo> are there CAN driver chips on the BBB? I'm guessing not...and missing termination as well I would guess... but I'm not an electrical engineer
Jul 21 18:23:56 <moto-timo> you might have more luck with SPI
Jul 21 18:26:32 <moto-timo> as an example implementation of SPI message Q: https://github.com/alexeicolin/tirtos/tree/master/packages/ti/tirtos/ipc
Jul 21 18:29:27 <ankur> thanks moto-timo but I have to test my code on CAN. It is a code for my gsoc project.
Jul 21 18:29:41 <ankur> it is working fine with vcan
Jul 21 18:30:07 <ankur> Is there any way to test it for CAN
Jul 21 18:30:16 <moto-timo> ankur: software protocol is probably fine, hardware is more difficult
Jul 21 18:31:29 <moto-timo> ankur: I bought one of these hoping to test it  https://www.ghielectronics.com/catalog/product/311
Jul 21 18:32:00 <moto-timo> ankur: it looks super simple and should let you get two BBBs talking over true CAN
Jul 21 18:33:22 <ankur> thanks moto-timo I will try it
Jul 21 18:34:19 <moto-timo> ankur: you'll need to buy two of course ;)
Jul 21 18:35:22 <ankur> yes :D
Jul 21 18:36:27 <ankur> moto-timo: isn't there any loop back configuration possible as in case of UART?
Jul 21 18:39:13 <moto-timo> you could probably use UART or SPI or I2C for loopback... UART would probably be the simplest
Jul 21 18:39:59 <ankur> ok
Jul 21 18:40:47 <moto-timo> ankur: look for tty0tty, that is a UART loopback package
Jul 21 19:30:30 <jkridner> moto-timo: I have one of those CAN guys too. I think I confirmed they are using a compatible PHY based on spec, but never tried booting.
Jul 21 20:14:06 <moto-timo> jkridner: good to know thanks
Jul 21 21:45:56 <ds2> hmmm
