Jan 01 04:58:30 <jlumme> any SPI experts here? specifically I'm having some strange issue trying to use spidev (I get illegal argument)
Jan 01 04:58:46 <jlumme> no modifications to the spidev_test.c, and still I get -22 from the driver
Jan 01 05:42:12 <emeb> Finally got around to putting that FPGA board into the Cape constest: http://beagleboard.org/CapeContest/entries/Blank+Canvas+Cape/
Jan 01 05:47:23 <mranostay> emeb_mac: last minute are we :)
Jan 01 05:48:16 <emeb_mac> if it weren't for the last minute, nothing would get done.
Jan 01 05:49:17 <mranostay> heh-- >  file:///home/ericb/KBADC/website/studionebula.com/embedded/bcc/index.html
Jan 01 05:49:21 <mranostay> oops
Jan 01 05:50:01 <emeb_mac> yeah - just spotted that.
Jan 01 05:50:16 <mranostay> seems everyone waiting to the last minute as well
Jan 01 05:50:22 <emeb_mac> the real URL is in the description on youtube
Jan 01 05:51:50 <mranostay> oh PRU porn
Jan 01 05:51:55 <mranostay> DMX cape
Jan 01 05:53:05 <emeb_mac> well - only 2 other FPGA capes so far. :P
Jan 01 05:54:03 <mranostay> pru LCD cape..
Jan 01 05:54:29 <mranostay> emeb_mac: don't forget the CPLD one
Jan 01 05:54:47 <emeb_mac> there's that.
Jan 01 06:22:24 <mph__> a CPLD cape?
Jan 01 06:22:30 <mph__> that i am interested in
Jan 01 06:22:45 <mph__> and there is a PRU cape?
Jan 01 06:23:06 <mph__> ??
Jan 01 06:25:15 <mph__> oh you teease>?
Jan 01 06:25:56 <emeb_mac> PRU on a cape would be kinda redundant, no?
Jan 01 06:26:11 <emeb_mac> how about an AM3358 cape?
Jan 01 06:28:40 <mph__> a cape that connected to the PRU on the AM3359 woudl be interesting
Jan 01 06:28:47 <mph__> but somehow i don't think it exisits
Jan 01 06:38:49 <mph__> is there a list of Capes?
Jan 01 06:42:18 <emeb_mac> you mean _all_ capes, or just contest entries?
Jan 01 06:42:39 <emeb_mac> here are the entries: http://beagleboard.org/CapeContest/entries/
Jan 01 07:01:40 <ka6sox> hiya
Jan 01 07:03:12 <emeb_mac> hey
Jan 01 07:03:29 <emeb_mac> Happy Gnu Ear to everyone in mountain time.
Jan 01 07:03:58 <mph__> h hah
Jan 01 07:06:56 <mph__> what to do with a cplu
Jan 01 07:10:49 <mranostay> mph__: my nixie prototype uses the pru
Jan 01 07:11:06 <mph__> the PRU, as in the network PRU?
Jan 01 07:12:15 <mranostay> programable realtime unit
Jan 01 07:13:09 <mph__> The PRU does a bunch of differnet thigns it seems
Jan 01 07:13:25 <emeb_mac> it's basically a tiny processor
Jan 01 07:13:50 <mph__> most interested in hearing about this
Jan 01 07:14:18 <mph__> are the PRU ports on the headers of the beagle
Jan 01 07:14:20 <ka6sox> The PRUs are nice for doing things on a predictable schedule.
Jan 01 07:14:37 <ka6sox> they attach to various pins (you can assign them)
Jan 01 07:14:45 <mph__> mmm
Jan 01 07:15:27 <mranostay> mph__: yeah muxed out
Jan 01 07:15:34 <mranostay> not documented in the SRM :)
Jan 01 07:15:49 <mph__> ethercat ports on the TI ICE board, are attached to the PRU
Jan 01 07:16:44 <ka6sox> iirc it can look @ a lot of the SoC
Jan 01 07:18:13 <mph__> what tripped me up intially was misunerstanding that the Ethernet ports whcih are attcehd to the internal 3 port switch are not the same as the ethercat ports
Jan 01 07:18:37 <mranostay> mph__: some pru code --> https://github.com/mranostay/beagle-nixie/
Jan 01 07:20:42 <mph__> ok, this is really interesting
Jan 01 07:21:29 <mph__> so, you are telling me that the PRU can be muxed onto various pins?
Jan 01 07:23:17 <ka6sox> yes
Jan 01 07:23:28 <ka6sox> I am intending to have it drive an SPI port
Jan 01 07:23:41 <mranostay> mine is basically SPI as well
Jan 01 07:24:01 <mph__> in theory...it should therefore be possible to create a set of ethercat ports on a beagle cape
Jan 01 07:24:03 <ka6sox> I need a constant stream of data or the Printer STOPS...
Jan 01 07:24:21 <mph__> 3d printer?
Jan 01 07:24:27 <ka6sox> ya
Jan 01 07:24:36 <ka6sox> yes, an arduino can drive one...
Jan 01 07:24:37 <mph__> i have a replicator
Jan 01 07:25:03 <mph__> im just implmenting a beagle into an electroplatter
Jan 01 07:25:05 <ka6sox> but I want to play with doing better accel/decel and smoothing
Jan 01 07:25:15 <mph__> very simple project
Jan 01 07:25:37 <ka6sox> let the FPGA convert from NURBS to drive the steppers smoothly
Jan 01 07:25:38 <mph__> got a bunch of ideas to do *stuff*
Jan 01 07:27:25 <mph__> so, were does one find some documetnation on these "featires" about the PRU
Jan 01 07:28:00 <ka6sox-away> nite all...
Jan 01 07:28:12 <ka6sox-away> us *old* folks can't make it till midnight...
Jan 01 07:28:21 <ka6sox-away> (j/k)
Jan 01 07:45:14 <mph__> the datasheet is calling again!
Jan 01 10:44:18 <mph__> i traced the pins through..
Jan 01 10:44:29 <mph__> just one problem.
Jan 01 16:31:14 <emeb_mac> 22 entries in the cape contest?
Jan 01 19:53:38 <ka6sox-away> mph__, this is my favourite google streetview: http://www.geekologie.com/2008/08/google-streets-now-with-drunks.php
Jan 01 19:54:46 <mph__> thanks.
Jan 01 19:54:57 <mph__> im gutted this morning
Jan 01 19:55:13 <mph__> i'm 4 pins short on the beagle headers
Jan 01 19:55:32 <mph__> to get the ports i need to build an ethercat interface
Jan 01 19:56:20 <ka6sox-away> better than shattered
Jan 01 19:57:15 * ka6sox-away read that as 4 pints short
Jan 01 20:04:38 <mph_> lol.
Jan 01 20:09:10 <emeb> ka6sox-away: did we win yet?? :)
Jan 01 20:10:33 <ka6sox-away> dunno...are the votes in?
Jan 01 20:10:49 <emeb> heh.
Jan 01 20:16:27 <mph_> vites for what?
Jan 01 20:19:05 <mph_> the beaglebone cape consttest is an incrediably cheap way of getting design work done.
Jan 01 20:21:29 <emeb> mdp_: cynical much. :)
Jan 01 20:23:38 <mph_> cynical yes
Jan 01 20:34:53 <alan_o> I wish I could build the kernel without optimizaiton :(
Jan 01 20:35:07 <alan_o> these stack traces mean almost nothing to me
Jan 01 20:36:50 <mph_> lol..
Jan 01 20:44:57 <mranostay> to another year of trolling
Jan 01 20:45:01 * mranostay waves
Jan 01 20:45:08 * alan_o raises his glass
Jan 01 20:46:31 <mranostay> alan_o: better not be Coors
Jan 01 20:46:52 <alan_o> hehe... I'd think not. I don't drink beer.
Jan 01 20:47:16 <mranostay> oh right
Jan 01 20:52:30 <alan_o> so mranostay... what am I supposed to do with this: http://pastebin.com/xbZ3ij95
Jan 01 20:52:47 <alan_o> I can't find __dabt_svc anywhere in the kernel source (or at least cscope can't)
Jan 01 20:53:23 <alan_o> hmm.... actually, I'm going to guess that's the exception handler
Jan 01 20:54:42 <aholler> use git grep
Jan 01 21:00:02 <alan_o> oh... it's asm
Jan 01 21:00:08 <alan_o> that's why cscope didn't find it
Jan 01 21:00:09 <alan_o> argh
Jan 01 21:25:17 <ka6sox-away> mranostay, resident troll
Jan 01 21:52:33 <mranostay> ka6sox-away: interim troll master
Jan 01 21:53:13 <alan_o> any indication as to when the master troll will be back on the throne/
Jan 01 23:47:28 <mph_> there is no barking today
Jan 01 23:50:19 <ka6sox> we let sleeping dogs lie
Jan 01 23:50:23 <ka6sox> er lay
Jan 02 02:00:02 <mranostay> back
Jan 02 02:06:55 <alan_o> font
Jan 02 02:06:57 <alan_o> arrgh
Jan 02 02:06:59 <alan_o> front
Jan 02 02:07:04 <alan_o> (joke is lost)
Jan 02 02:19:43 <mranostay> alan_o: keep the day job
Jan 02 02:58:17 <mph_> hes awake
