Apr 18 03:06:24 <Turl> CareBear\: the current cubieboard has 100M ethernet, the new one that's on the pipelines should have GigE
Apr 18 03:06:56 <jkridner|work> am335x has a dual gigE controller.  just need CCo to make a cost effective board solution ;-)
Apr 18 03:08:14 <Turl> :)
Apr 18 03:08:42 <ds2> isn't there a evm for the 335x that has the gigE exposed?
Apr 18 03:09:08 <prpplague> ds2: yea there is
Apr 18 03:09:54 <prpplague> ds2: uses the same ar8031 gige phy as the wandboard
Apr 18 03:10:11 <prpplague> (and minnowboard)
Apr 18 03:39:53 <jkridner|work> $199 starter kit has gigE
Apr 18 03:45:18 <ds2> but can the 335x saturate the GigE?
Apr 18 03:49:28 <prpplague> ds2: yea, very quickly
Apr 18 05:22:10 <av500> ahoi
Apr 18 05:22:18 <dm8tbr> polloi
Apr 18 05:27:28 <BeagleGithub> [kernel] koenkooi pushed 1 new commit to 3.8: http://git.io/XNczDw
Apr 18 05:27:28 <BeagleGithub> kernel/3.8 a097e17 Koen Kooi: 3.8: update to 3.8.8...
Apr 18 05:32:13 <dm8tbr> av500: how's the sailing? arrived and scouting for ELCC locations yet?
Apr 18 05:34:44 <av500> we can have it in my back yard
Apr 18 05:41:17 * mranostay harlems shakes in
Apr 18 05:44:43 <panto> gm
Apr 18 05:47:38 <nbprashanth> Good morning everyone. I was going through the GSoC topics and I would like to discuss and understand more regarding the project "Library of Arduino-compatible functions for Linux".
Apr 18 05:48:53 <nbprashanth> Is this the preferred channel for GSoC discussions?
Apr 18 05:50:58 <av500> yep
Apr 18 05:51:09 <KotH> this is the prefered channel for discussions on guns, JIHAD, chocolate and sometimes also discussions on GSoC
Apr 18 05:51:38 <KotH> and a little warning, as you are new here: do not trust either me or av500
Apr 18 05:52:14 <nbprashanth> Hmmm.... I keep that in mind. :P
Apr 18 05:52:27 <av500> :)
Apr 18 05:52:41 <av500> nbprashanth: if you have question, just ask
Apr 18 05:53:36 <nbprashanth> I was wondering if i understood the problem. As i understand, the project aims to have a library compatible to that of arduino's but on the backend, it will make use of linux API's. Is that right?
Apr 18 05:54:02 <nbprashanth> So it would be to essentially port/rewrite the arduino library for a linux target...
Apr 18 05:54:53 <nbprashanth> Am i right?
Apr 18 05:55:32 <av500> yes
Apr 18 05:56:58 <nbprashanth> Okay... I would like to take up this project for GSoC as I have worked quite a bit with Arduino and have programming experience with linux. What would the preferred way to start?
Apr 18 05:57:20 <nbprashanth> I read on the wiki that the students have to demonstrate that they can properly cross compile.
Apr 18 05:58:24 <nbprashanth> Is there anything else?
Apr 18 05:58:44 <av500> for now the student application is not yet "open"
Apr 18 05:58:49 <av500> I think thats from the 22nd on
Apr 18 05:58:52 <av500> yes
Apr 18 05:59:00 <av500> the qualification task is there
Apr 18 05:59:45 <av500> nevertheless you can use the time to work on a proposal
Apr 18 05:59:47 <av500> gather ideas
Apr 18 06:00:35 <nbprashanth> Hmmm. By qualification task, you mean the demonstration of cross compilation?
Apr 18 06:03:15 <av500> yes
Apr 18 06:03:28 <av500> I know, its too hard :)
Apr 18 06:05:57 <nbprashanth> :P
Apr 18 06:07:29 <nbprashanth> Okay. I ll try to get a hello world program cross compiled now. Have to download the toolchains...
Apr 18 06:17:59 <nbprashanth> Alright... I got the ARM toolchain on ubuntu and used arm-linux-gnueabi-gcc-4.7 to compile a program with no errors.
Apr 18 06:18:05 <nbprashanth> Is this the right way?
Apr 18 06:29:23 <nbprashanth> av500: I guess I cross compiled a hello world program. What's next?
Apr 18 06:30:11 <nbprashanth> I used the arm toolchain on ubuntu 13.04 but I guess there is an angstorm linux toolchain for beagle board.
Apr 18 06:30:38 <nbprashanth> I hope this is what you expected.
Apr 18 06:30:44 <av500> http://elinux.org/BeagleBoard/GSoC/Ideas#General_requirements
Apr 18 06:31:20 <nbprashanth> Ah. Okay. It's point no 8. Sorry....
Apr 18 06:55:49 <nbprashanth> Ummm, I dont have access to an ARM machine as such. Is it possible for anyone here to test the binary?
Apr 18 06:58:09 <ynezz> there's free arm machine called qemu
Apr 18 06:59:22 <nbprashanth> Yes, I have heard of Qemu before. But I would need an ARM based OS image, right?
Apr 18 06:59:42 <ynezz> running binaries from unknown sources is not safe
Apr 18 06:59:53 <nbprashanth> Hmm. Understandable.
Apr 18 06:59:53 <Russ> you can actually use qemu to run arm binaries directly
Apr 18 07:00:15 <nbprashanth> Oh. I didn't know that. I ll check it out now. Thanks.
Apr 18 07:01:10 <joel_> http://balau82.wordpress.com/2010/02/28/hello-world-for-bare-metal-arm-using-qemu/
Apr 18 07:01:38 <joel_> kind of an old one, but fwiw
Apr 18 07:02:10 <nbprashanth> Thanks joel_ . I'll check it out.
Apr 18 07:03:39 <joel_> np
Apr 18 07:05:30 * joel_ wonders if anyone is still working on OMAP emulation on qemu
Apr 18 07:05:45 <joel_> lot of dead projects floating around dated 2-3 years atleast.
Apr 18 07:06:24 <joel_> qemu does have a beaglexm target
Apr 18 07:08:24 <nbprashanth> Alright! It works!! :). Thanks all!!
Apr 18 07:08:39 <nbprashanth> I ll go ahead and send a pull request for the code.
Apr 18 07:16:44 <nbprashanth> av500, Anything else I can do for the project now? I read the wiki and it mentions only the cross compilation.
Apr 18 07:16:52 <nbprashanth> What would be next step?
Apr 18 07:17:27 <av500> well, you could do some thinking/planning on the task you want to apply for
Apr 18 07:19:26 <nbprashanth> Hmm. Okay. I ll work on it and prepare a draft report and put it up somewhere...
Apr 18 07:30:38 <mranostay> hi joel_ !!!
Apr 18 07:30:55 <KotH> mranostay: shouldnt you be in bed?
Apr 18 07:31:18 <mranostay> bah you aren't my mom
Apr 18 07:32:04 <KotH> but i could be your dad
Apr 18 07:32:40 <mranostay> unlikely as all hell
Apr 18 07:37:03 <av500> mranostay: I AM YOUR FATHER!
Apr 18 07:37:46 <mranostay> oh god i hope not
Apr 18 07:38:47 <av500> that girl you kissed, that was yous sister btw
Apr 18 07:38:51 <av500> your*
Apr 18 08:08:40 <KotH> mranostay: now you should kill av500 and become our local oedipus
Apr 18 08:30:27 <ka6sox-farfarawa> has anyone seen davest in a few days?
Apr 18 08:36:30 <panto> ka6sox-farfarawa, let's say that things are a bit hectic before DW
Apr 18 08:36:37 <panto> I'll ping him for you when he shows up
Apr 18 08:41:48 <koen> ka6sox-farfarawa: he's on vacation in turkey
Apr 18 08:43:22 <ka6sox-farfarawa> koen, panto I had heard he might have been in Boston is why I asked.
Apr 18 08:43:53 <panto> ka6sox-farfarawa, I'm not sure where he is right now, I know he's swamped
Apr 18 08:44:14 <panto> ka6sox-farfarawa, I started looking at the jtag pru thing too
Apr 18 08:44:27 <ka6sox-farfarawa> oh good...got ideas?
Apr 18 08:44:42 <panto> well, it seems quite possible
Apr 18 08:44:51 <panto> the clocks aren't that fast
Apr 18 08:44:57 <panto> and openocd would be a cinch
Apr 18 08:45:13 <panto> I was thinking about something one bit further
Apr 18 08:45:19 <ka6sox-farfarawa> right the only fast things are the PISO/SIPO bits which are hardware assisted.
Apr 18 08:45:36 <ka6sox-farfarawa> okay...do tell.
Apr 18 08:46:06 <panto> looking at all the small uC dev environment all are a bit hard to setup and use
Apr 18 08:46:19 <panto> have to hunt down for a whole bunch of stuff to get it to work on your env
Apr 18 08:46:35 <panto> plus most people develop on windows which makes things even more difficult
Apr 18 08:47:03 <panto> for small uC, the bone is fast enough to have the full toolchain and run an ide (over ajax or what not)
Apr 18 08:47:31 <ka6sox-farfarawa> oh very much so.
Apr 18 08:47:54 <panto> think of a cape that would accept standard uC dev modules, autodetect everything and allow you to compile/run/debug on the bone
Apr 18 08:48:13 <ka6sox-farfarawa> so for MSP/Arduino/Pi we use the Bone as a dev machine...love it.
Apr 18 08:48:25 <panto> yes, it's quite nice
Apr 18 08:48:31 <panto> let's make a product out of it
Apr 18 08:48:59 <panto> perhaps even route the i2c/spi interface to some spare bone pins so that we can run something like a logic analyzer
Apr 18 08:49:30 <ka6sox-farfarawa> let me get thru with La-OCD-Bone-Tag first.
Apr 18 08:49:34 <panto> I know it's pretty far off, but for people that only care about developing for arduino/msp/ etc...
Apr 18 08:49:59 <panto> no pc installs, just plug it on the network and go
Apr 18 08:50:12 <ka6sox-farfarawa> the only issue I see with MSP is that CCS only works on Doze... :P
Apr 18 08:50:28 <panto> scratch msp then
Apr 18 08:50:30 <ka6sox-farfarawa> I'm not sure how mature gcc-msp is now...
Apr 18 08:50:34 <panto> although there is a gcc port
Apr 18 08:50:37 <ka6sox-farfarawa> right
Apr 18 08:50:56 <ka6sox-farfarawa> last time I looked (18months ago) it had "issues"
Apr 18 08:51:04 <panto> yeah, that's expected
Apr 18 08:51:16 <KotH> ka6sox-farfarawa: the bone as a dev machine?
Apr 18 08:51:18 <panto> but I started looking at contiki too, and they seem to have a gcc port
Apr 18 08:51:31 <KotH> ka6sox-farfarawa: ie you hook up monitor and keyboard to it?
Apr 18 08:51:33 <panto> KotH, for compiling 64K is plenty fast
Apr 18 08:51:36 <ka6sox-farfarawa> KotH, for uC...plenty o'horse power
Apr 18 08:51:47 <panto> KotH, no need, you can just run a web ide
Apr 18 08:51:48 <KotH> hmm.. why a bone and not a standard pc?
Apr 18 08:51:52 <panto> there are plenty
Apr 18 08:51:53 <ka6sox-farfarawa> KotH, via ssh or some kind of Wire setup.
Apr 18 08:51:59 <panto> KotH, cause users are stoopid
Apr 18 08:52:18 <KotH> ah.. to give them a black box that just works?
Apr 18 08:52:19 <panto> and the support cost of fixing every crap windows/mac osx/linux issue will kill you
Apr 18 08:52:24 <panto> yes
Apr 18 08:52:25 <ka6sox-farfarawa> KotH, yup.
Apr 18 08:52:34 <KotH> nice idea!
Apr 18 08:52:45 <ka6sox-farfarawa> ya...like that too.
Apr 18 08:52:50 <panto> I know people do that with VMs, but even VMs have their issues
Apr 18 08:52:57 * KotH nods
Apr 18 08:53:03 <ka6sox-farfarawa> VMs can't programme hardware well.
Apr 18 08:53:10 * KotH nods again
Apr 18 08:53:26 <ka6sox-farfarawa> so that means you *still* have the issue of getting the code *into* the device.
Apr 18 08:53:37 <panto> I have some econotags, some CCs and some mrfs
Apr 18 08:54:05 <ka6sox-farfarawa> well...teh little AVR JTAG bits would work fine.
Apr 18 08:54:09 <panto> having the jtag interface on the bone is just so seamless
Apr 18 08:54:13 <ka6sox-farfarawa> ya
Apr 18 08:54:37 <panto> and nothing forbids you using it as a jtag interface for faster CPUs
Apr 18 08:54:47 <ka6sox-farfarawa> okay I almost forgot to add the 6 pin AVR plug too.
Apr 18 08:54:49 <panto> although for that I'd like a real gbit ethernet
Apr 18 08:55:29 <ka6sox-farfarawa> depends on what you are flashing...
Apr 18 08:55:29 <panto> I don't know how far we can get with just a cape on the bone
Apr 18 08:55:48 <panto> perhaps a custom white-label design would be more optimal
Apr 18 08:55:57 <panto> but for small uCs it should be just fine
Apr 18 08:56:16 <ka6sox-farfarawa> I think for a lot of things it would work fine...especially with OCD
Apr 18 08:56:39 <panto> ka6sox-farfarawa, there are cases where I had to flash a full linux kernel + rootfs cause the nand controller didn't work at all, and there was no ethenet :)
Apr 18 08:56:49 <ka6sox-farfarawa> ouch
Apr 18 08:56:55 <panto> oh yeah
Apr 18 08:57:23 <panto> I like the fact that I can use tools that I've made/can understand
Apr 18 08:57:40 <ka6sox-farfarawa> thats helpful too.
Apr 18 08:58:11 <ka6sox-farfarawa> the little MSP Launchpad bits have that USB port for them...
Apr 18 08:58:23 <ka6sox-farfarawa> for the G series
Apr 18 08:58:30 <panto> ftdi jtag?
Apr 18 08:58:50 <ka6sox-farfarawa> for something that small...the little launch pad is like $4
Apr 18 08:59:00 <ka6sox-farfarawa> iirc $4.30
Apr 18 08:59:04 <panto> link?
Apr 18 08:59:15 <ka6sox-farfarawa> and it does a lot of devices in the G series
Apr 18 09:00:07 <panto> the beauty of this is that we could make all of this seamless
Apr 18 09:00:11 <ka6sox-farfarawa> http://www.mouser.com/ProductDetail/Texas-Instruments/MSP-EXP430G2/?qs=CLImetaeaXWH2pYG%252bA%252b4Vw%3D%3D&gclid=CJ7I35nt07YCFQg6nAodjmUACw
Apr 18 09:00:16 <ka6sox-farfarawa> so its $10
Apr 18 09:00:25 <panto> plug in the avr cape, everything gets configured and ready to go for it
Apr 18 09:00:26 <ka6sox-farfarawa> but occasionally they go on sale for $4.30
Apr 18 09:00:30 <panto> same as with msp, etc.
Apr 18 09:00:36 <ka6sox-farfarawa> right...
Apr 18 09:00:42 <panto> no configuration, just plug it and go
Apr 18 09:00:58 <Mohamed> hello everybody
Apr 18 09:00:58 <ka6sox-farfarawa> so its more of a Pro-Debug Cape
Apr 18 09:01:05 <ka6sox-farfarawa> morning Guest81796
Apr 18 09:01:23 <panto> ka6sox-farfarawa, let's get the jtag bit done first
Apr 18 09:01:23 <ka6sox-farfarawa> panto, thats doable
Apr 18 09:01:31 <ka6sox-farfarawa> right.
Apr 18 09:01:45 <panto> target a few well known uC dev boards
Apr 18 09:01:55 <ka6sox-farfarawa> the CPLD/Clock I've worked with will do 10Mb to 160Mb
Apr 18 09:02:04 <ka6sox-farfarawa> (not that you can really go 160Mb)
Apr 18 09:02:11 <Guest81796> i have made nand erase all in my s3 device can i repair it or it was dead ??
Apr 18 09:02:24 <ka6sox-farfarawa> s3?
Apr 18 09:02:27 <av500> s3?
Apr 18 09:02:29 <panto> does it have a beaglebone in it?
Apr 18 09:02:39 <panto> a beagleboard?
Apr 18 09:02:40 <Guest81796> samsung galaxy s3 i9300
Apr 18 09:02:47 <av500> wrong channel
Apr 18 09:02:52 <ka6sox-farfarawa> ya
Apr 18 09:02:52 <panto> you're definitely at the wrong channel
Apr 18 09:02:56 <av500> also, it's just a phone
Apr 18 09:02:59 <av500> buy a new one
Apr 18 09:03:04 <ka6sox-farfarawa> :)
Apr 18 09:03:04 <Guest81796> i don't know
Apr 18 09:03:08 <panto> hell, buy two
Apr 18 09:03:15 <panto> give one to the missus
Apr 18 09:03:25 <panto> worth lots of party favors
Apr 18 09:03:25 <av500> Guest81796: here: http://www.bunniestudios.com/blog/?p=3040
Apr 18 09:04:09 <Guest81796> your ass is red
Apr 18 09:04:18 <ka6sox-farfarawa> panto, so I think we will have to have pru0 do TX and pru1 do RX
Apr 18 09:04:29 <av500> alas
Apr 18 09:04:31 <ka6sox-farfarawa> b00m
Apr 18 09:04:36 <av500> but how did he know?
Apr 18 09:04:41 <ka6sox-farfarawa> he he
Apr 18 09:04:44 <panto> hehe
Apr 18 09:04:53 <panto> kids these days
Apr 18 09:04:56 <ka6sox-farfarawa> ya
Apr 18 09:05:05 <panto> ka6sox-farfarawa, yep
Apr 18 09:05:21 <ka6sox-farfarawa> I always love the folks that ask about house training their beagle here :)
Apr 18 09:05:41 <panto> I got mine all trained up
Apr 18 09:05:49 <panto> I hardly ever see it peeing all over my desk
Apr 18 09:06:01 <panto> perhaps we should make a urine-cape
Apr 18 09:06:06 <av500> ka6sox-farfarawa: and then the people that need actual potty training ...
Apr 18 09:06:19 <ka6sox-farfarawa> there are more than a few of those.
Apr 18 09:07:27 <ka6sox-farfarawa> panto, so I can either have everyone buy very expensive adapter cables....or add a bunch of connectors.
Apr 18 09:07:51 <ka6sox-farfarawa> 14/20/8/6
Apr 18 09:08:00 <panto> unpopulated connector would be fine
Apr 18 09:08:12 <ka6sox-farfarawa> oh, make them solder the ones they want on?
Apr 18 09:08:22 <panto> I suppose each one that buys one would know what he wants to target
Apr 18 09:08:22 <ka6sox-farfarawa> interesting idea
Apr 18 09:08:29 <ka6sox-farfarawa> right
Apr 18 09:08:41 <panto> you can sell variants
Apr 18 09:08:59 <ka6sox-farfarawa> I like it...kind of like a BDI3000 with the various targets :)
Apr 18 09:09:03 <panto> hehe
Apr 18 09:09:39 <panto> you can always have a single connector that carries all the signals
Apr 18 09:09:43 <ka6sox-farfarawa> panto, how can I syncronize the PRU's....
Apr 18 09:10:01 <ka6sox-farfarawa> ya, I can do like a 20 pin that carries everything and build adapter cables.
Apr 18 09:10:14 <ka6sox-farfarawa> and charge $$$ for them too!
Apr 18 09:10:18 <panto> yep
Apr 18 09:10:22 <av500> ka6sox-farfarawa: btw, the launchpad at TI is much cheaper
Apr 18 09:10:24 <panto> if one doesn't want to solder, pay
Apr 18 09:10:30 <ka6sox-farfarawa> right
Apr 18 09:10:39 <ka6sox-farfarawa> av500, ya, I thought so.
Apr 18 09:10:44 <ka6sox-farfarawa> iirc it was $4.30
Apr 18 09:10:48 <av500> ah no
Apr 18 09:10:52 <av500> they upped the price
Apr 18 09:10:55 <ka6sox-farfarawa> heh
Apr 18 09:11:07 <panto> $4.30 sounds like heavily subsidized
Apr 18 09:11:17 <ka6sox-farfarawa> so can we sync the PRU's?
Apr 18 09:11:20 <av500> panto: yes
Apr 18 09:11:24 <panto> ka6sox-farfarawa, I'll check up on that
Apr 18 09:11:30 <ka6sox-farfarawa> like a common IRQ Line?
Apr 18 09:11:35 <av500> panto: 4.30 was cheaper than the 2 MSPs on board and the TUSB
Apr 18 09:11:37 <panto> they have events
Apr 18 09:11:41 <ka6sox-farfarawa> ah
Apr 18 09:11:42 <ka6sox-farfarawa> okay
Apr 18 09:12:04 <panto> or if push comes to shove you can route inputs to outputs externally and sync from there
Apr 18 09:12:16 <panto> I'll have to read up on it a bit to let you know exactly how
Apr 18 09:12:19 <ka6sox-farfarawa> mranostay, wanted a LA...and this could do it *if* we can sync the 2 pru's
Apr 18 09:12:56 <panto> you know there's a 'hidden' way to access the IO of one of the PRUs from the other right?
Apr 18 09:13:26 <panto> so if you're IO limited and not throughput limited that's the way to do it more easily
Apr 18 09:13:56 <ka6sox-farfarawa> what we need is to be able to push 16bits (or more) across the bus @ 1 time
Apr 18 09:14:00 <ka6sox-farfarawa> all reading
Apr 18 09:14:14 <ka6sox-farfarawa> so we can oversample the 8 input lines.
Apr 18 09:15:10 <panto> so you want more inputs, not really faster operation
Apr 18 09:15:39 <ka6sox-farfarawa> for the LA he wants 8 bits...
Apr 18 09:16:00 <ka6sox-farfarawa> that limits the speed because of the need to shuffle the bits thru the GPI bus.
Apr 18 09:16:48 <panto> what if we have a really really simple IO expander on?
Apr 18 09:16:58 <ka6sox-farfarawa> I saw a way to shuffle from GPI to R30 (or is it r31) in 1 cycle.
Apr 18 09:17:02 <panto> like reading twice gets X2 pins
Apr 18 09:17:32 <panto> we would cut speed in half though
Apr 18 09:17:40 <ka6sox-farfarawa> right...
Apr 18 09:17:45 * av500 should have ordered more launchpads at $4.30
Apr 18 09:18:06 <ka6sox-farfarawa> I think I can configure the CPLD to up speed at cost of less bits.
Apr 18 09:18:06 <KotH> av500: why buy a launchpad if you can get a complete phone?
Apr 18 09:18:16 <av500> hmm
Apr 18 09:18:49 <ka6sox-farfarawa> I looked at a 8168 board once...about fainted.
Apr 18 09:19:12 <KotH> tms320?
Apr 18 09:19:22 <ka6sox-farfarawa> I think its a Sitara part.
Apr 18 09:19:26 <av500> netra
Apr 18 09:19:31 <ka6sox-farfarawa> ya that one
Apr 18 09:19:42 <av500> 3x HDVICP
Apr 18 09:19:51 <panto> $4K ? :)
Apr 18 09:19:55 <av500> sure
Apr 18 09:20:09 <ka6sox-farfarawa> ya, but this is for medical camera dev.
Apr 18 09:20:25 <ka6sox-farfarawa> so they did buy it.
Apr 18 09:20:50 * panto has to do some work today 
Apr 18 09:20:51 <KotH> heh. medical... with all the paperwork involved, any hardware is cheap
Apr 18 09:20:59 <ka6sox-farfarawa> yup
Apr 18 09:21:06 <ka6sox-farfarawa> I need sleep..its 2am here.
Apr 18 09:21:09 * KotH is glad he doesnt have to deal with the FDA
Apr 18 09:21:17 <KotH> night ka6sox-farfarawa
Apr 18 09:21:22 <panto> g'night ka6sox-farfarawa
Apr 18 09:21:24 <ka6sox-farfarawa> panto, laters we can talk about this some more...I think you are on to something.
Apr 18 09:21:32 <ka6sox-farfarawa> nite KotH
Apr 18 09:21:37 <panto> cya
Apr 18 09:31:42 <KotH> WTH... the weather cape costs as much as the bone itself???
Apr 18 09:33:13 <koen> yeah, $25 humidity sensor in the BOM
Apr 18 09:34:15 <KotH> o_0
Apr 18 09:34:22 <KotH> the SHT21 shouldnt be that expensive
Apr 18 09:35:11 <KotH> hmm..what do that put into that? gold pressed latinuum?
Apr 18 09:35:43 * KotH has to tease....ask his friend
Apr 18 09:35:44 <av500> KotH: is a 2G modem that talks to weather.com
Apr 18 09:43:47 <KotH> av500: hmm.. if we compare it to that $12 phone... that might indeed be the case
Apr 18 09:44:23 <KotH> koen: i gues you get the SHT21 over distributors
Apr 18 09:44:33 <KotH> koen: ever considered getting them from sensirion directly?
Apr 18 09:44:46 <KotH> might save a couple of bucks
Apr 18 09:44:47 <koen> I'd have to ask the purchasing guys
Apr 18 09:45:27 <KotH> i know that for the ETH research projects we get them from sensirion directly
Apr 18 09:45:32 <KotH> and i doubt they pay full price
Apr 18 09:46:13 <KotH> (ok, it might help that sensirion is located in the same city and most of the employees are ex-ETH guys/girls)
Apr 18 10:10:43 <nml> s-video output: works in angstrom, but with ubuntu 12.10, the screen goes black (after showing booting text) just before loading lxde. bbxm-c1
Apr 18 10:12:13 <KotH> sounds like there is a problem with your x server
Apr 18 10:12:22 <KotH> check /var/log/X.org.0.log
Apr 18 10:15:15 <nml> (very new  to linux) check with: sudo nano /var/log/X.org.0.log ?
Apr 18 10:15:38 <Turl> or just cat
Apr 18 10:22:42 <nml> http://pastebin.com/ycq1d5Ew
Apr 18 10:25:17 <KotH> nml: if you dont want to edit a file, but just look at it, use "less"
Apr 18 10:26:22 <nml> ok, thanks
Apr 18 10:28:34 <nml> do I need to set x window config file to a different monitor as well?
Apr 18 10:29:25 <mru> mrpackethead: http://youtu.be/pCDEiaoEP2U
Apr 18 10:29:40 <mrpackethead> oh yeah.
Apr 18 10:29:46 <mrpackethead> we are all raindbowed out
Apr 18 10:47:01 <mdp> hrmph, not friday yet
Apr 18 10:49:03 <panto> hi mdp
Apr 18 10:49:09 <mdp> panto, hello
Apr 18 10:49:21 <mdp> panto, been a little busy and kinda half caught the pru discussions here
Apr 18 10:49:36 <panto> I knew you'd like it
Apr 18 10:49:47 <panto> jtag pru was your idea after all :)
Apr 18 10:49:49 <mdp> was there a problem using the same dual pru debug reg scheme I used to read 8 contiguous bits
Apr 18 10:50:22 <mdp> which, in proper foss fashion, wasn't my idea...taken from lyren brown's atari project
Apr 18 10:50:47 <panto> art is all about stealing from the best around
Apr 18 10:51:01 <mdp> just like patent disclosures
Apr 18 10:52:54 <mdp> from my studies, that's the only way to get 8 contiguous inputs lined up properly
Apr 18 10:53:13 <mdp> if the PRU was sanely integrated in a different SoC it would be a completely different story
Apr 18 10:53:27 <panto> sanity is overrated
Apr 18 10:53:38 <panto> the whole world is a hack, why cpu design should be different
Apr 18 10:54:07 <mdp> well, meaning doing a 2 cycle-ish read and having it in one byte of the register for manipulation == sane to me
Apr 18 10:54:21 * mdp blows panto off the internets
Apr 18 10:55:10 <panto> hum, hungry
Apr 18 10:55:16 <panto> bbl
Apr 18 11:37:55 <KotH> He told his German middle ear, outage ran up to sausage from the second pliers, to bisect his things and justify on, and he prodigy went up to her.
Apr 18 11:38:16 <_troll_> wtf
Apr 18 11:38:29 <KotH> just received that in a "mail" :)
Apr 18 11:38:41 <KotH> thought, i'd share ;)
Apr 18 11:43:18 <varun2902> Hi
Apr 18 11:43:45 <varun2902> I have an idea for node.js
Apr 18 11:44:04 <varun2902> Collaborative Code Management
Apr 18 11:44:11 <varun2902> ?
Apr 18 11:45:29 <varun2902> Anybody interested there ?
Apr 18 11:45:53 <av500> norwegian is fun: Archos 101 XS er et nettbrett med høy plastfaktor
Apr 18 11:46:50 <_troll_> it's true
Apr 18 11:48:56 <dm8tbr> lol
Apr 18 11:50:03 <varun2902> Anyone for Node.js
Apr 18 11:51:49 <av500> neither for nor against
Apr 18 11:52:00 <av500> also, you dont really elaborate
Apr 18 11:54:37 <varun2902> Collaborative Code Management - people working on same project but cant manage the whole code and finally end up with difficulties in integrating each others work
Apr 18 11:55:34 <varun2902> so i thought of using node.js ans socket.io so that team members can spectate each others work and can do their own
Apr 18 11:56:34 <varun2902> Whole project files n folders will be common but concurrency control will manage
Apr 18 11:57:40 <av500> like github?
Apr 18 11:58:39 <koen> or gobby?
Apr 18 11:58:43 <koen> or google docs?
Apr 18 11:58:51 <av500> or a shared ftp server?
Apr 18 11:58:53 <koen> or subethaedit ?
Apr 18 11:59:08 <_troll_> paste the code into a google-doc and hack away, what could possibly go wrong
Apr 18 11:59:09 <dm8tbr> or screen -x
Apr 18 12:00:18 <varun2902> yeah but the advantage is that in github we have to first do our work then commit then push,others will pull and all....but here the whole poject would reside at one place
Apr 18 12:00:48 <koen> sounds like you are trying to solve a social problem with a technical solution
Apr 18 12:01:32 * _troll_ fails to see how it relates to beagleboard
Apr 18 12:02:10 <varun2902> Yeah true !
Apr 18 12:02:10 * KotH fails to see how constantly changing code should ever compile
Apr 18 12:02:11 <av500> that too
Apr 18 12:02:20 <av500> KotH: its javascript
Apr 18 12:02:23 <av500> its not compiled
Apr 18 12:02:29 <KotH> so it's ever failing?
Apr 18 12:02:42 <_troll_> javascript never fails, it just does something arbitrary
Apr 18 12:02:48 <av500> wat?
Apr 18 12:03:59 <varun2902> Compilation would be on their own desktop but they can upload the same right on server so that each one can be awae of what others are doing
Apr 18 12:04:07 <varun2902> can collaborate easily
Apr 18 12:04:20 * dm8tbr senses an jo dawg joke in there somewhere
Apr 18 12:04:38 <av500> sounds like remote pair programming to me
Apr 18 12:04:48 <av500> use some desktop sharing solution
Apr 18 12:05:01 <av500> still, how does it relate to beagle?
Apr 18 12:05:19 <varun2902> Node.js application
Apr 18 12:05:34 <KotH> how does it relate to beagle?
Apr 18 12:05:36 <av500> still, how does it relate to beagle?
Apr 18 12:05:55 <ogra_> does it relate to beagle ?
Apr 18 12:10:52 <KotH> you can run node.js on a beagle
Apr 18 12:10:56 <KotH> if you have to
Apr 18 12:11:09 <KotH> and someone is holding a gun to your head
Apr 18 12:11:18 <av500> he gaveth up on us
Apr 18 12:12:21 <ogra_> sounded like an educational project .... we should have pointed him to RPi
Apr 18 12:12:35 <KotH> heh
Apr 18 12:13:26 <mdp> hrm, cleveland TI Tech Day has a "Introduction to BeagleBone Black" in the ARM Processors track
Apr 18 12:13:30 <mdp> fascinating
Apr 18 12:13:47 <KotH> so we are officially allowed to use that colour again?
Apr 18 12:13:52 <mdp> ;)
Apr 18 12:14:03 <mdp> I must have missed the memo that the embargo was lifted
Apr 18 12:14:38 <mdp> KotH, it's on the public agenda
Apr 18 12:15:35 <Tartarus> mdp, but when is the Tech Day?
Apr 18 12:15:48 <Tartarus> I saw on G+ someone else posted a link to the CCO wiki
Apr 18 12:15:54 <mdp> yes
Apr 18 12:16:02 <Tartarus> and "embargoed until april 25" or whatever was in the snippet even
Apr 18 12:16:06 <av500> we are hunting him down as we speak
Apr 18 12:16:15 * av500 sets 4chan on the guy
Apr 18 12:16:19 <mdp> right, it seems people have exposed some stuff early
Apr 18 12:16:40 <mdp> Tartarus, the tech day is after..I'll bet they just have no way to update the schedule
Apr 18 12:16:44 <Tartarus> Yeah
Apr 18 12:16:45 <mdp> probably a TI IT thing ;)
Apr 18 12:17:09 <av500> mdp: well, the cco wiki is "public"
Apr 18 12:17:16 <av500> somebody "found" the url
Apr 18 12:17:18 <KotH> they could have named it "Introduction to BeagleBone <unnamed colour>" :)
Apr 18 12:17:32 <mdp> av500, right, maybe TI should "fire" CCO for ruining things
Apr 18 12:17:49 <Tartarus> mdp, the big surprise is that you'll be the one running the session, they just haven't told you yet :)
Apr 18 12:18:02 <av500> mdp: who is that TI girl that urges me daily to blog about black?
Apr 18 12:18:13 <mdp> http://www.ti.com/ww/en/techdays/2013/docs/cleveland_abstracts.pdf
Apr 18 12:18:22 <mdp> av500, jessica?
Apr 18 12:18:27 <av500> yep
Apr 18 12:19:45 <Tartarus> mdp, I see it doesn't say who is running the track.  So you're ready for a package of beagle supplies to show up at your door right?
Apr 18 12:20:11 <av500> who is ruining the track.....
Apr 18 12:20:13 <mdp> heh
Apr 18 12:20:45 <mdp> when we were in that group last year, I offered to do this one..but they said the toronto sales team didn't want an ARM track at this venue
Apr 18 12:20:56 <mdp> apparently this year it's needed
Apr 18 12:21:02 <av500> ARM is a passing fad after all
Apr 18 12:21:54 <mdp> to be fair, more of the customers in this area are at the msp430/lm4f level
Apr 18 12:22:02 <av500> lm4 is gone
Apr 18 12:22:05 <av500> ot Tivo now
Apr 18 12:22:09 <KotH> long live tm4c!
Apr 18 12:22:10 <av500> it's*
Apr 18 12:23:10 <mdp> Tivo to Go!
Apr 18 12:23:56 <fewe> hi
Apr 18 12:24:07 <fewe> is there a board diagnostic procedure available for beagle xm?
Apr 18 12:24:13 <av500> yes
Apr 18 12:24:31 <av500> http://www.google.de/search?sourceid=chrome&ie=UTF-8&q=beagleboard+diagnistic
Apr 18 12:24:38 <av500> http://www.google.de/search?sourceid=chrome&ie=UTF-8&q=beagleboard+diagnostic
Apr 18 12:25:03 <mdp> "tester"
Apr 18 12:25:23 <fewe> Yes I googled it before coming here
Apr 18 12:25:49 <fewe> but the wiki says the xm diagnostic says it's stil under development (last update on july 2011)
Apr 18 12:26:05 <av500> perpetual beta
Apr 18 12:26:27 <KotH> providurium
Apr 18 12:26:34 <av500> it might be easier if you state a problem
Apr 18 12:27:15 <fewe> my problem is that i have several boards which do not boot anymore
Apr 18 12:27:31 <fewe> they do not even provide the few characters when booting without an sd card
Apr 18 12:27:36 <fewe> over the uart
Apr 18 12:27:43 <av500> not good
Apr 18 12:27:49 <fewe> yes i know :)
Apr 18 12:27:55 <av500> with user button pressed?
Apr 18 12:28:02 <fewe> nop
Apr 18 12:28:12 <fewe> just plugged in the serial port
Apr 18 12:28:17 <fewe> and powered it up
Apr 18 12:28:51 <fewe> do you want me to try with the user button? Shouldn't be detected as there is no sd card
Apr 18 12:28:53 <fewe> right?
Apr 18 12:29:12 <av500> user button might not be needed on XM
Apr 18 12:29:13 <av500> I forgot
Apr 18 12:30:38 <fewe> I just tried powering up the board with the user button pressed
Apr 18 12:30:45 <fewe> nothing
Apr 18 12:31:01 <fewe> and without the user button, and after power up pressing the user btn
Apr 18 12:31:08 <fewe> not output
Apr 18 12:31:09 <fewe> no*
Apr 18 12:31:14 <KotH> do all power rails have the correct voltage?
Apr 18 12:31:24 <KotH> does the oscillator oscillate?
Apr 18 12:31:34 <fewe> nothin on the oscillator
Apr 18 12:31:43 <fewe> i din't check the power rails though
Apr 18 12:31:53 <KotH> check the basics first ;)
Apr 18 12:32:14 <mdp> Tartarus, I do wonder who's coming to do that Sitara track ;)
Apr 18 12:32:34 <KotH> hmm... according to some top secret wiki, some top secret colour dog board should be shipping tomorrow
Apr 18 12:32:37 <fewe> KotH: should the leds light up if the power rails are failing?
Apr 18 12:32:43 <KotH> fewe: no
Apr 18 12:32:58 <KotH> fewe: there is more than one power rail and the leds are not connected to all of them
Apr 18 12:33:51 <fewe> So i have the usb led lighting up, the power led lighting up, and the D5 led is also lit up
Apr 18 12:34:39 * KotH doesnt know where those leds are connected to
Apr 18 12:35:05 <fewe> KotH: ok then :)
Apr 18 12:35:26 <KotH> get the schematics, read it, measure the rails, ???, profit
Apr 18 12:35:40 <KotH> oh.. dont forget to JIHAD, and CHOCOLATE
Apr 18 12:35:59 <KotH> last time i forgot to add those two in the exact steps and the guy got very upset
Apr 18 12:36:11 <fewe> uh?
Apr 18 12:36:25 <panto> fewe, ignore the swiss troll
Apr 18 12:36:32 <fewe> :)
Apr 18 12:36:38 <panto> the whole channel has been dropped on it's head when it was a baby
Apr 18 12:36:47 <panto> each one is busted in a different way
Apr 18 12:38:09 * KotH teaches the greek troll on the difference of "its" and "it's" ;)
Apr 18 12:38:21 <KotH> hmm.. looks like i scared him away
Apr 18 12:38:31 <mdp> I told him to get off the internet
Apr 18 12:38:35 <fewe> well you made him fly away
Apr 18 12:38:35 <mdp> gtfo
Apr 18 12:39:32 <KotH> mdp: you dont seem to be very successfull with that
Apr 18 12:40:31 <mdp> KotH, if I can get his state telecom folks to strike..I can easily get him off the internets
Apr 18 12:40:44 <mdp> just a slight nudge should do the trick
Apr 18 12:42:31 <panto> not a very hard to do
Apr 18 12:42:40 <panto> you can just wait until tuesday
Apr 18 12:42:52 <mdp> it's shameful really, no more challenge than trolling rmk
Apr 18 12:43:01 <mdp> forget the idea, we can do better
Apr 18 12:43:39 <KotH> rmk?
Apr 18 12:43:50 <mdp> the king
Apr 18 12:44:01 <panto> king of trollees
Apr 18 12:45:24 * KotH thought the _troll_ was the king
Apr 18 12:45:30 <KotH> he even has wings!
Apr 18 12:45:35 <mdp> panto, don't be a "dickface" ;)
Apr 18 12:45:41 <panto> lol
Apr 18 12:45:43 <bradfa> _troll_ gives you wings?
Apr 18 12:45:46 <fewe> ok I just check the 5V and VIO on the expansion header
Apr 18 12:46:00 <fewe> v is ok but the VIO is 0.7 instead of 1.8
Apr 18 12:46:13 <fewe> 5v is ok*
Apr 18 12:46:43 <KotH> and the core power rail?
Apr 18 12:46:57 <panto> http://bit.ly/11gFETB <- probably NSFW
Apr 18 12:46:57 <fewe> hmmm
Apr 18 12:48:38 * KotH seen worse at work
Apr 18 12:49:34 <KotH> http://www.youtube.com/watch?v=GvlFJmh6ktU <- do not watch this if you are at a work place that has "high" moral values
Apr 18 12:49:50 <KotH> (but good pre-friday stuff nevertheless)
Apr 18 12:50:37 <fewe> vdd 2 semms ok (1.2 V)
Apr 18 12:50:45 <fewe> vDD1 sorry
Apr 18 12:50:55 <av500> KotH: looks like a typical US college dorm movie
Apr 18 12:51:32 <av500> also teal and red
Apr 18 12:51:37 <KotH> av500: probably a bit more graphic and more realistic than the typical college dorm movie
Apr 18 12:51:54 <av500> never go to florida during spring break then
Apr 18 12:52:04 <KotH> i actually would like to do that
Apr 18 12:52:12 <fewe> both VDD1 and VDD2 are 12.v
Apr 18 12:52:16 <fewe> 1.2V*
Apr 18 12:52:17 <KotH> and if possible, before i turn 40
Apr 18 12:54:00 * mdp continues to wait for something new in the horror/suspense/vampire/monster/zombie genre
Apr 18 12:55:45 <av500> mdp: how about intel shipping HTML5 tooling?
Apr 18 12:55:54 <mdp> +1
Apr 18 12:56:14 <mdp> definitely a lot of tools there
Apr 18 12:56:14 <fewe> So what should I do if the VIO is 0.7?
Apr 18 12:56:21 <av500> add 1.1V
Apr 18 12:56:24 <fewe> :D
Apr 18 12:56:37 <fewe> RMA?
Apr 18 12:57:03 <av500> seems so
Apr 18 13:02:50 <fewe> Is it possible to do a batch rma? I have 5 or 6 boards showing the same symptoms
Apr 18 13:03:13 <av500> talk to CCO
Apr 18 13:03:36 <fewe> the manufacturing company right?
Apr 18 13:03:42 <av500> yes

Apr 18 14:40:18 <GPIOproblem> hi guys. I need help with creating  a script on my beagle xm rev c, running angstrom distrubution. script should with every reboot work so that GPIO = 4 ( user button ) can start an .C file.
Apr 18 14:41:43 <av500> do you have the script?
Apr 18 14:43:06 <GPIOproblem> well, i have an example script which can output some lines when button is pressed, from this website( http://bbfordummies.blogspot.dk/2009/07/1.html )
Apr 18 14:43:43 <GPIOproblem> but i need to change that somehow, but dont know exactly how. some pointers would be very helpfull
Apr 18 14:46:08 <av500> GPIOproblem: well, writing a script is like writing a program
Apr 18 14:46:14 <av500> can you program?
Apr 18 14:46:46 <GPIOproblem> i can program a little bit. can understand programming. this is my first time using C, i am used to JAVA.
Apr 18 14:48:29 <av500> well, shell scripts are not C
Apr 18 14:49:13 <_troll_> might be csh
Apr 18 14:49:24 <KotH> who in his right mind uses csh?
Apr 18 14:49:36 <_troll_> who said anything about right mind?
Apr 18 14:50:55 <KotH> right, it could be a left minded person
Apr 18 14:51:11 <av500> a leftist
Apr 18 14:51:24 <GPIOproblem> okey.. but where would i start? i got some hints, that in the /etc/ library on angstrom there should be a script which is loaded standard. And in the bottom of that script i could add my GPIO code. ??
Apr 18 14:51:31 <av500> no
Apr 18 14:51:38 <av500> 1) write your script
Apr 18 14:51:42 <av500> 2) worry how to start it
Apr 18 14:51:45 <av500> you are at 1)
Apr 18 14:52:07 <av500> for a start, run your script manually
Apr 18 14:53:37 <GPIOproblem> well i did, and it runs.
Apr 18 14:54:00 <av500> and when you press a button it starts a program?
Apr 18 14:54:14 <av500> the user button in fact
Apr 18 14:56:10 <GPIOproblem> no, i linked to a blog, i followed that example. when i run gpio_read ( 4 in my case) it runs the program, and everytime i hit the button, it does what the program says it will do, it draws an character --> ^, when not pressed it draws this -> _
Apr 18 14:58:44 <av500> awesome
Apr 18 14:58:50 <av500> now modify it to do what you want
Apr 18 15:06:37 <GPIOproblem> yep. trying right now..
Apr 18 15:18:05 <KotH> av500: you should have become a teacher
Apr 18 15:18:14 <KotH> av500: you'd be quite a good one
Apr 18 15:18:31 <KotH> (and intimidating one too)

Apr 18 15:22:35 <KotH> good morning ka6sox-notthatfaraway
Apr 18 15:23:15 <KotH> av500: did you have something like spick (www.spick.ch) in germany?
Apr 18 15:24:06 <KotH> av500: ie a magazine for elementary school children that tried to teach you something and didnt tell you what boy group is hip?
Apr 18 15:24:22 <av500> when I was in elementary school, sadly I had no internet
Apr 18 15:24:37 <KotH> it was (and still is) a print magazine
Apr 18 15:25:02 <KotH> and very swiss.. just like globi
Apr 18 16:13:44 <av500> koen: Linuxtag?
Apr 18 16:15:54 <koen> av500: hopefully
Apr 18 16:16:02 <av500> as in booth?
Apr 18 16:16:05 <av500> or just go?
Apr 18 16:16:58 <koen> just go
Apr 18 16:17:02 <av500> ic
Apr 18 16:17:14 <av500> know which days?
Apr 18 16:17:37 <koen> straddling linuxnacht
Apr 18 16:17:43 <av500> right
Apr 18 16:17:52 <_troll_> you're going to that shitty "party"?
Apr 18 16:18:12 <av500> we can always drink beer outside :)
Apr 18 16:18:17 <koen> yes
Apr 18 16:18:25 <koen> or go to the chinese restaurant next to cbase
Apr 18 16:18:31 <_troll_> you do that
Apr 18 16:18:38 <woglinde> koen lol
Apr 18 16:18:58 <woglinde> thats full of undercover agents from the chinese embassay
Apr 18 16:19:00 <av500> koen: or we go troll woglinde
Apr 18 16:19:08 * ogra_ will be there ... 
Apr 18 16:19:16 <woglinde> trool trool trool
Apr 18 16:19:17 <av500> gee
Apr 18 16:19:21 <koen> woglinde: it had food when we were tired of waiting for the bbq :)
Apr 18 16:19:27 * woglinde gets a truck full of beer
Apr 18 16:19:30 <woglinde> from orga
Apr 18 16:19:39 <ogra_> oh, indeed
Apr 18 16:19:56 <ogra_> a chrome truck even :)
Apr 18 16:20:34 <woglinde> hm yes ubuntu bbq
Apr 18 16:20:38 <woglinde> never were there
Apr 18 16:36:52 <KotH> does anyone here have access to IPC-7351B and could tell me what the differences to IPC-7351 (the 2005 version) are? google doesnt give any good results
Apr 18 17:00:23 <hitlin37> next beaglebone will be v7 based?
Apr 18 17:00:32 <panto> ?
Apr 18 17:01:02 <hitlin37> arch
Apr 18 17:01:23 <panto> it's the same CPU, only faster, so yes
Apr 18 17:01:49 <koen> v7 doesn't say much
Apr 18 17:02:02 <koen> e.g. the m4 is v7m
Apr 18 17:02:07 <panto> I guess he means armv7
Apr 18 17:02:45 <hitlin37> yes.
Apr 18 17:03:22 <panto> so, yeah all your code running on the old bone will run fine
Apr 18 17:03:30 <koen> same thing
Apr 18 17:03:39 <koen> cortex m4 is armv7m
Apr 18 17:03:48 <koen> you mean armv7a
Apr 18 17:04:19 <panto> koen, nitpicker you... :)
Apr 18 17:04:36 <woglinde> whats m?
Apr 18 17:04:40 <woglinde> modified
Apr 18 17:06:12 <KotH> micro controller
Apr 18 17:06:20 <KotH> replacement for the arm7
Apr 18 17:06:41 <KotH> (respectively for the 16bit uC's when talking about m0)
Apr 18 17:06:54 <hitlin37> Yes.i meant armv7-a.
Apr 18 17:07:06 * KotH blinks
Apr 18 17:07:13 <KotH> wave solder for smd components??
Apr 18 17:07:25 <KotH> what the heck have those people been smoking?
Apr 18 17:09:15 <ds2> you can wave them
Apr 18 17:10:48 <_troll_> KotH: m0 is just as 32-bit as any other arm
Apr 18 17:11:15 <KotH> yes it is, but it is targetet to replace 16bit uCs
Apr 18 17:11:29 <KotH> targeted*
Apr 18 17:11:47 <ds2> but the M arms run a mostly 16bit instruction set
Apr 18 17:12:05 <KotH> thumb2?
Apr 18 17:12:08 <KotH> yes, so?
Apr 18 17:12:13 <_troll_> the _instructions_ are mostly 16-bit
Apr 18 17:12:16 <_troll_> the _data_ is 32-bit
Apr 18 17:12:43 <ds2> so let's call this a 24bit system ;)
Apr 18 17:12:47 <_troll_> so by your reckoning, amd64 is a 12-bit machine
Apr 18 17:12:49 <KotH> ds2: most people have been using thumb with the arm7 already
Apr 18 17:12:51 <_troll_> on average
Apr 18 17:12:57 <KotH> lol
Apr 18 17:13:01 <ds2> yep. no loving for amd64
Apr 18 17:13:22 <_troll_> actually, the average is probably a lot higher
Apr 18 17:13:24 <ds2> why you think they trying to make a 64bit server chip ;)
Apr 18 17:13:57 <ds2> KotH: but one is not required to do so on the A chips
Apr 18 17:14:14 <KotH> yes
Apr 18 17:14:16 <KotH> different target
Apr 18 17:15:03 <ds2> you ain't got a choice with 'em M's
Apr 18 17:16:10 <KotH> ds2: a typical cortex-m system has no display, runs at 10-50MHz, sleeps 90% of the time, has no OS running on it, uses a couple of mA of power and musst not cost more than 10USD at low volumes
Apr 18 17:17:28 <ds2> I question that 'typical' definition
Apr 18 17:17:36 <KotH> why?
Apr 18 17:17:40 <ds2> if that is true, then most makers of the M chips should be out of business
Apr 18 17:17:50 <KotH> why?
Apr 18 17:18:03 <ds2> you got folks touting 72MHz, 144MHz M's
Apr 18 17:18:16 <ds2> and do cost more then $10 in low volumes
Apr 18 17:18:18 <_troll_> a lot of m cores are used as helpers in largers chips
Apr 18 17:18:33 <ds2> plus you got the FreeRTOS folks who can't possibly exists
Apr 18 17:18:52 <ds2> and a lot of those chips do pull in the order of 10's of MA
Apr 18 17:19:06 <ds2> think that's almost every point of your 'typical'!
Apr 18 17:19:45 <ds2> oh and many makers are touting an apparently useless waste of silicon LCD controller
Apr 18 17:20:06 <ds2> >>
Apr 18 17:20:09 <ds2> oops
Apr 18 17:20:15 <KotH> ds2: very few applications need the high end M's (mostly M4 these days), and even those are <20USD at single piece
Apr 18 17:21:32 <KotH> _troll_: one of our designs contains an arm926 for application + display, and an cortex-m3 to toggle a single switch :-)
Apr 18 17:22:07 <hitlin37> even sifteo cubes are m based.it even has display.
Apr 18 17:23:00 <ds2> those are M3's I am thinking of
Apr 18 17:23:06 <KotH> ds2: compare how many of the cortex-m chips have a display controller
Apr 18 17:23:13 <KotH> ds2: very few actually do
Apr 18 17:23:16 <bradfa> Oh CCO, I enjoy the wiki antics :)
Apr 18 17:23:25 <ds2> KotH: most of the ones I looked at do
Apr 18 17:23:36 <ds2> which surprised me
Apr 18 17:23:46 <KotH> then you looked at the higher end ones :)
Apr 18 17:23:52 <ds2> Cypress, Silabs, ST to name a few... think even the Stellaris ones
Apr 18 17:23:53 <bradfa> KotH, I'm with ds2 here, lots and lots of M3 and M4s have display controller
Apr 18 17:23:54 <KotH> with lots of pins
Apr 18 17:23:55 <ds2> all M3's
Apr 18 17:24:08 <ds2> what's lots of pins? those have 64pin packages
Apr 18 17:24:20 <bradfa> Atmel M4s come in 100+ pin versions
Apr 18 17:24:32 <bradfa> and USB high speed!
Apr 18 17:24:56 <ds2> there are M3 dev boards with a on board LCD
Apr 18 17:25:24 <KotH> ds2: that's a lot of pins ;)
Apr 18 17:25:35 <ds2> KotH: how many pins are you referring to?
Apr 18 17:25:38 <ds2> 8? 5? 3?
Apr 18 17:25:41 <KotH> ds2: we regularly do designs with 48pin chips :)
Apr 18 17:25:45 <_troll_> 54
Apr 18 17:25:49 <bradfa> balls
Apr 18 17:26:10 <KotH> ds2: unless we have lots of space, then we use the 64pin ones, because they are easier to design with
Apr 18 17:26:12 <ds2> they probally have 48 pin versions, I didn't look at them as I needed an EMIF
Apr 18 17:26:38 <ds2> not very useful to do a parallel EMIF in a 48pin package ;)
Apr 18 17:27:08 <KotH> bradfa: iirc the stm32f4 is available in a 208 pin version :)
Apr 18 17:27:14 <ds2> having said that... an 8 pin M0 chip would be nice
Apr 18 17:27:37 <bradfa> ds2, NXP low end M0 is < $1
Apr 18 17:28:20 <KotH> ds2: nxp has a 8 pin cortex-m
Apr 18 17:28:22 <ds2> bradfa: yes but is that a typical chip that gets used?
Apr 18 17:28:27 <KotH> ds2: iirc it's an m0
Apr 18 17:28:30 <ds2> Oooooooo 8pin M's
Apr 18 17:28:48 <ds2> but it probally don't have a cross bar inside, right?
Apr 18 17:28:52 <bradfa> lpc800 has 8 pin dip package
Apr 18 17:28:53 <ds2> <-- lazy about layout
Apr 18 17:29:03 <KotH> ds2: i didnt have a look
Apr 18 17:29:11 <bradfa> lpc800 is popular, I believe
Apr 18 17:29:11 <KotH> ds2: too few pins, cannot connect anything ;)
Apr 18 17:29:20 <bradfa> KotH, use imagination, I hear that helps
Apr 18 17:29:21 <bradfa> :)
Apr 18 17:29:28 <bradfa> and unicorns
Apr 18 17:29:36 <ds2> KotH: who needs pins...use the Cypress chips and do it on board ;)
Apr 18 17:29:45 <ds2> on chip I mean
Apr 18 17:29:47 <bradfa> isn't everything wireless, yet?
Apr 18 17:29:56 <bradfa> we don't need no stinkin wires!
Apr 18 17:30:20 <KotH> bradfa: i'm currently working on a design, where we had to fit a uC, power supply from 24V, rs-485 driver, flash and acceleration sensor on a 7x15mm board :)
Apr 18 17:30:46 <bradfa> KotH, sounds like fun :)
Apr 18 17:31:02 <KotH> bradfa: you should have heard the cursing of the guy who did the layout :)
Apr 18 17:31:06 <bradfa> what has 24 V power and has to fit in that size?
Apr 18 17:31:23 <bradfa> I'd expect battery for something that small
Apr 18 17:31:31 <KotH> oh.. we have that too
Apr 18 17:31:49 <KotH> that stuff has to run 2 years (at least) from two SR48 batteries, when no external power connected
Apr 18 17:32:29 <KotH> it's an acceleration sensor for warranty assesment in a high precision mechanical component that cost a couple 10k a piece
Apr 18 17:33:16 <bradfa> neat
Apr 18 17:50:18 <mranostay> bradfa: hey hw guy
Apr 18 18:04:50 <woglinde> reeeeeeeeeeeeeeee
Apr 18 18:31:33 <bradfa> mranostay, hey gerber guy?
Apr 18 18:34:38 * mdp throws jars of baby food at mranostay
Apr 18 18:36:02 <bradfa> mdp, that stuff's expensive!
Apr 18 18:36:17 <mdp> indeed
Apr 18 18:36:31 <mdp> nothing too rich for Gerber Guy(™) :P
Apr 18 18:42:43 <KotH> short english question: does "round off" mean "round to nearest number" or "round down to nearest number" ?
Apr 18 18:44:56 <_av500_> round tuit
Apr 18 18:45:53 <mdp> KotH: it means it's poorly written
Apr 18 18:46:03 <_chase_> KotH: I speak for myself but "round off" to me mean round down to the nearest number.  i.e. round off the fraction.
Apr 18 18:46:07 <_chase_> or what mdp said
Apr 18 18:46:27 <_av500_> in Texas they round 'em up
Apr 18 18:46:33 <mdp> +1
Apr 18 18:46:44 <KotH> unfortunately, that's a poorly written standard that i must extract some sense out
Apr 18 18:46:46 <mdp> because everything's bigger
Apr 18 18:47:01 <_chase_> and don't you forget it neither
Apr 18 18:47:40 <dm8tbr> WTH is a cortex A5?
Apr 18 18:48:03 <ynezz> sedan
Apr 18 18:48:08 <Tartarus> one third of an A15?
Apr 18 18:48:15 <ynezz> oh, that's audi
Apr 18 18:48:20 <keesj> and half a A10
Apr 18 18:48:52 <_av500_> actually
Apr 18 18:49:10 <dm8tbr> I know the A7 is a low power a15, but what's an a5 meant to be?
Apr 18 18:49:15 <Tartarus> an A10 is a plane
Apr 18 18:49:15 <dm8tbr> cut down a9?
Apr 18 18:49:42 <keesj> there is also the Allwinner A10 (and A20 now)
Apr 18 18:49:51 <_av500_> and A13
Apr 18 18:49:53 <_av500_> and A31
Apr 18 18:49:55 <keesj> but that's just socs
Apr 18 18:50:16 <_av500_> A5 is a highway here
Apr 18 18:50:20 <mdp> clearly the question was about the cores
Apr 18 18:50:31 <_av500_> it's a core topic
Apr 18 18:50:49 <mdp> A1 was the name of so many companies here before Google totally ruined the whole yellow pages thing
Apr 18 18:50:55 <dm8tbr> oh, the A5 seems to be some sort of armv6 successor thing, has armv7 but sucks otherwise
Apr 18 18:50:59 <keesj> ARM version numbers and "implementation" number are just weird :p armv5 arm9 WTF
Apr 18 18:51:03 <_av500_> wasnt it AAAAAAAAAAAAAAAAAAAAAAAAAAAA1?
Apr 18 18:51:05 <mdp> jerks
Apr 18 18:51:12 <dm8tbr> I wonder how long until there's an rpi with it...
Apr 18 18:51:23 <_av500_> dm8tbr: I have an 4xA5 phone on my desk
Apr 18 18:51:29 <_av500_> its quite -.... usable
Apr 18 18:51:45 <dm8tbr> that fake note thing?
Apr 18 18:51:46 <mdp> _av500_:yeah AAAAAAAAAAAAAAAAAAAAAAAA1 Auto Repair
Apr 18 18:51:54 <_av500_> dm8tbr: no, that is MTK
Apr 18 18:52:03 <_av500_> dual A9 thta is
Apr 18 18:52:11 <dm8tbr> oh, ic
Apr 18 18:52:28 <_av500_> so a quad A5 is not too bad for a phone
Apr 18 18:52:37 <dm8tbr> i guess a quad a5 is a marketing thing. 'quad core' [x]
Apr 18 18:52:39 <keesj> arn't iphone cores also name "A6" etc?
Apr 18 18:52:47 <_av500_> yes
Apr 18 18:53:03 <_av500_> had we made our own SoC a few years back, we would have beat apple to the A1
Apr 18 18:56:03 <mdp> _av500_, yours would have had a media player embedded in it
Apr 18 18:56:09 <mdp> the whole application
Apr 18 18:56:13 <_av500_> :)
Apr 18 18:56:19 <_av500_> not really
Apr 18 18:56:31 <_av500_> mdp: but something like the ABE
Apr 18 18:57:15 <mdp> _av500_, the h/w guys at motorola used to tell our team how complex their ASIC designs were versus simple software
Apr 18 18:57:32 <_av500_> yeah, sw is simple
Apr 18 18:57:41 <mdp> so my colleague asked them if they were so complex why don't they implement a simple spreadsheet program in the next one
Apr 18 18:57:52 <_av500_> mdp: the SoC guys told us back then we could throw in as many ARM7 cores inside as we wanted
Apr 18 18:58:05 <_av500_> ARM9 did cost a bit
Apr 18 18:58:05 <mdp> yeah, just throw in there
Apr 18 18:58:33 <_av500_> so we planned an ARM7 and SRAM to buffer PCM and let the main cpu sleep
Apr 18 18:59:26 <mdp> remoteproc ;)
Apr 18 18:59:39 <_av500_> more like ABE in the phoenix
Apr 18 18:59:40 <mdp> "never been done before"
Apr 18 18:59:55 <_av500_> intel had something similar in Moorestown
Apr 18 19:00:01 <mdp> yeah
Apr 18 19:00:45 <mdp> I finally hit that point now where everything looks like it was recycled from 15 years ago
Apr 18 19:01:09 <_av500_> waiting for the ISA bus to come back?
Apr 18 19:01:46 <mdp> _av500_, more like, there's just nothing really new
Apr 18 19:02:04 <panto> yep
Apr 18 19:02:10 <panto> the cycle of reincarnation
Apr 18 19:02:22 <mdp> which is what those gray-hairs kept lamenting back in '95
Apr 18 19:02:22 <panto> I hope you've read that old paper
Apr 18 19:02:52 <mdp> and I thought they were crazy...but listened because they had all the knowledge

Apr 18 19:03:24 <mdp> panto, that sounds familiar
Apr 18 19:03:51 <woglinde> let the compiler do the hard parts

Apr 18 19:06:28 <mdp> right
Apr 18 19:06:42 <mru> isn't that still vapourware?
Apr 18 19:06:53 <panto> no idea
Apr 18 19:07:01 <_av500_> the soc itself exist
Apr 18 19:07:02 <mdp> about to ship
Apr 18 19:07:17 <_av500_> now its only about selling it at the kickstarter backers at a loss
Apr 18 19:07:22 <panto> but even if it isn't, the premise stands: super-parallel systems tend to fail at the market
Apr 18 19:07:27 <_av500_> and making it up in volume

Apr 18 19:09:25 <panto> what about gurus in parallel with linux
Apr 18 19:09:27 <mdp> cause you need just the control plane stuff to relaly do anything

Apr 18 19:19:14 <panto> standard linux device pwms
Apr 18 19:19:18 <mdp> panto, the lib exists
Apr 18 19:20:02 <mdp> proper approach would be 1) pwm virtio driver 2) remoteproc/virtio driver for pruss 3) pruss f/w load with virtio device header
Apr 18 19:20:04 <panto> prussdrv.c?
Apr 18 19:21:08 <mdp> in fact, that's the use case I had in mind as an example before I got reassigned ;)
Apr 18 19:21:26 <panto> dunno seems a bit too roundabout
Apr 18 19:21:34 <mdp> it's the standard
Apr 18 19:21:54 <mdp> I think you can do whatever you want in the evil kernel
Apr 18 19:22:03 <mdp> but it'll never go upstream like that
Apr 18 19:22:15 <mdp> actually, I guarantee it
Apr 18 19:22:20 <mdp> my personal guarantee
Apr 18 19:22:40 <mdp> it's simpler than you might think too
Apr 18 19:22:48 <panto> enlighten me
Apr 18 19:23:46 <mdp> a generic pwm virtio driver would simple define a virtual pwm device via 1..n virtqueues
Apr 18 19:24:15 <mdp> it's probably a 200-ish line generic driver that would be reused for anybody's remoteproc
Apr 18 19:24:39 <mdp> mailbox driver exists already
Apr 18 19:25:15 <mdp> remoteproc driver is just a slight variation on the trivial uio_pruss.c
Apr 18 19:25:47 <mdp> then the f/w load you were going to write anyway..only using the well-defined virtio standard to define 1..n pwms
Apr 18 19:26:08 <panto> hmm, I'll give it a shot
Apr 18 19:26:17 <mdp> again, I'm jealous

Apr 18 22:34:32 <David_____> ya
Apr 18 22:34:57 <mranostay> that is a 'temp' register

Apr 18 22:35:21 <David_____> but dont some register is used for certain things
Apr 18 22:35:28 <mranostay> not really in ARM
Apr 18 22:35:37 <David_____> for example r3 is for destination
Apr 18 22:36:00 <David_____> isnt that reserved?

Apr 18 22:38:18 <calculus> but not at the moment :)
Apr 18 22:38:24 <David_____> so i can use any register and its not reserved?
Apr 18 22:38:42 <Russ> rule 30?

Apr 19 00:04:01 <thaha> Hi, I want to boot Angstrom only on the serial port. I have a Beagleboard xM rev C. I downloaded and followed steps from the angstrom-demo page.
Apr 19 00:04:14 <thaha> how to do this?
Apr 19 00:13:49 <ka6sox> mranostay, I'd like an R10 but I doubt its street legal in california
Apr 19 00:31:26 <thaha> hello?
Apr 19 00:31:54 <prpplague> goodbye
Apr 19 00:33:25 <alan_o> thaha: you represent the boilermakers well.
Apr 19 00:33:41 <alan_o> what can we do for you?
Apr 19 00:36:45 <jackbowen> hey there. I'm a prospective google summer of code student and I was just wondering if this was the place to run potential project ideas past mentors?
Apr 19 00:37:27 <ds2> sure
Apr 19 00:37:28 <alan_o> jackbowen: maybe. Especially if jkridner|work or jkridner  is around
Apr 19 00:37:32 <ds2> or beagle-gsoc
Apr 19 00:37:54 <jkridner|work> this is the place.... or #beagle-gsoc
Apr 19 00:38:23 <jkridner|work> probably best to pull in potential mentors from here and take the detailed conversation over to #beagle-gsoc
Apr 19 00:39:16 <thaha> alan_o: Thanks for replying. I am trying to get my Beagleboard booted in cmdline on serial port
Apr 19 00:39:21 <ungureanuvladvic> jkridner|work: i would have some questions about the android project...but all mentors tell me to speak with you...maybe when you have a bit of free time to discuss
Apr 19 00:39:33 <thaha> I downloaded the latest images from the Angstrom demo site
Apr 19 00:40:04 <jackbowen> jkridner|work: great! well I'm mainly interested developing the bonescript web pages so I believe that you would be my mentor on that one?
Apr 19 00:40:14 <thaha> I can see the serial output till "Uncompressing Linux".
Apr 19 00:40:20 <ds2> Yikes!
Apr 19 00:40:22 <thaha> After that I suspect the output is going into dvi
Apr 19 00:40:26 * ds2 runs a million miles away
Apr 19 00:40:32 <alan_o> thaha: not likely
Apr 19 00:40:43 <alan_o> thaha: Where'd you get the images?
Apr 19 00:40:44 <jkridner|work> jackbowen: yeah... new pages should launch next week.
Apr 19 00:40:59 <alan_o> thaha: is this an xm or bone?
Apr 19 00:41:02 <thaha> http://downloads.angstrom-distribution.org/demo/beagleboard/
Apr 19 00:41:03 <jkridner|work> current pages are at https://github.com/jadonk/bone101
Apr 19 00:41:11 <thaha> alan_o:xM rev C
Apr 19 00:41:13 <jkridner|work> er, well, pages about to launch are there.
Apr 19 00:42:19 <thaha> I searched online for sometime.... I think it has to do with bootargs
Apr 19 00:42:33 <alan_o> thaha: what did you download from there?
Apr 19 00:43:02 <thaha> alan_o: Angstrom-Beagleboard-demo-image-glibc-ipk-2011.1-beagleboard.rootfs.tar.bz2 , MLO, u-boot.img
Apr 19 00:43:08 <thaha> I followed the instructions beneath
Apr 19 00:43:18 <nbprashanth> jkridner|work, Hi. I am interested in the "Library of Arduino-compatible functions for Linux" project for GSoC. I have submitted a pull request after recompiling the hello world code... I would like to discuss the scope of this project further with you and find out how I may begin working towards it.
Apr 19 00:43:31 <jkridner|work> ungureanuvladvic: I wouldn't say I ever have free time....
Apr 19 00:43:41 <jkridner|work> but, you'll never get an answer if you don't ask the question.
Apr 19 00:43:49 <ds2> jkridner|work: when you flying?
Apr 19 00:44:00 <jkridner|work> Monday morning to San Jose.
Apr 19 00:44:26 <jkridner|work> probably should have gone on Sunday.
Apr 19 00:44:48 <ds2> you got peons arriving Sunday to setup?
Apr 19 00:44:57 <nbprashanth> jkridner|work, Is there anything i can do now to get started on the arduino project?
Apr 19 00:45:06 <jkridner|work> nope... I'm setting up on Monday.
Apr 19 00:45:08 <alan_o> thaha: I think there's a good chance you have something mismatched
Apr 19 00:45:27 <ds2> is gerald coming?
Apr 19 00:45:48 <jkridner|work> Gerald was planned to, but might commit himself to the funny farm. :-)
Apr 19 00:45:55 <thaha> alan_o: do you know if I put in a boot.scr in the boot partition
Apr 19 00:46:20 <jkridner|work> nbprashanth: I think prpplague has an Energia fork that is a useful starting point....
Apr 19 00:46:20 <thaha> and setenv bootargs 'console=ttyO2,115200n8 serialtty=ttyO2'
Apr 19 00:46:23 <thaha> will that work?
Apr 19 00:46:32 <jkridner|work> he just has printfs where the hardware accesses should go...
Apr 19 00:46:55 <alan_o> thaha: which kernel is it?
Apr 19 00:46:57 <jkridner|work> you can look at bonescript as one approach and do a lot of googling to see how the hardware accesses *should* be done.
Apr 19 00:47:01 <jackbowen> jkridner|work: Hey I just took a look a look through the bonescript pages and they're a lot more comprehensive than I thought. Would the role of the student be predominantly front end development in this case? Thanks for the immediate feedback by the way.
Apr 19 00:47:25 <jkridner|work> mostly adding a bunch of new hardware components.
Apr 19 00:47:32 <ungureanuvladvic> jkridner|work: i was thinking about the booting from the phone, but this case is just for debugging boards. maybe to put the board in command of the phone.
Apr 19 00:47:36 <jkridner|work> showing people how to hook up motors, LED strips, etc.
Apr 19 00:47:54 <ds2> any 40KV generators?
Apr 19 00:48:01 <alan_o> thaha: are you getting through u-boot?
Apr 19 00:48:05 <jkridner|work> I'd send a care package from Sparkfun and Adafruit and the idea would be to create interactive web examples on how to use them.
Apr 19 00:48:06 <ds2> got to naturally generate the black ;)
Apr 19 00:48:09 <thaha> yes
Apr 19 00:48:15 <thaha> Everything is fine
Apr 19 00:48:28 <thaha> I just want the linux to load on serial port
Apr 19 00:48:32 <thaha> rather than on my dvi
Apr 19 00:48:41 <alan_o> thaha: DVI has nothing to do with it
Apr 19 00:49:05 <thaha> oh but i think inside the bootargs it is automatically set to dvi
Apr 19 00:49:13 <prpplague> nbprashanth: i have a good starting point, you just need to start filling in the commands
Apr 19 00:49:21 <jkridner|work> ungureanuvladvic: I think av500 had a lot of opinions on the android-boot project.
Apr 19 00:49:26 <alan_o> thaha: at some point, the console moved from ttyS2 to ttyO2. I'm trying to decide whether the 2011.11 version is before or after that
Apr 19 00:49:58 <ds2> alan_o: 2.6.38+ kernels want the omap uart driver. prior versions use the 8250 drivedr
Apr 19 00:50:23 <alan_o> ds2: any idea which one is in the 2011.11 image?
Apr 19 00:50:33 <ds2> no idea
Apr 19 00:50:42 <ds2> I don't follow angstrom images, sorry.
Apr 19 00:50:45 <thaha> where do i find the kernel version?
Apr 19 00:50:58 <alan_o> ds2: me neither, unless I'm helping someone who's asking for one
Apr 19 00:51:00 <ds2> guessing it is 2.6.38 since koen abandoned 2.6.32 a long time ago
Apr 19 00:51:13 <jackbowen> Okay great! That sounds like a blast. Is there anything specific that you're looking to see in a project proposal?
Apr 19 00:51:52 <ka6sox> ah okay
Apr 19 00:52:13 <prpplague> jkridner|work: argh this 3dprinter is going to be the death of me
Apr 19 00:52:41 <ds2> prpplague: we'll print up a coffin for you with it if that happens ;)
Apr 19 00:52:55 <prpplague> ds2: lovely
Apr 19 00:52:55 <ds2> prehaps even a printed gravemarker? :D
Apr 19 00:53:10 <jackbowen> jkridner|work:And can the deliverables be a mix of media? i.e. some code, some interactive pages, some videos
Apr 19 00:53:12 <thaha> alan_o: printenv at the omap console gives me this argument
Apr 19 00:53:18 <ds2> prpplague: which one? I am finally getting time to get back to mine
Apr 19 00:53:20 <thaha> ompa.dvi
Apr 19 00:53:24 <thaha> **omap.dvi
Apr 19 00:53:28 <alan_o> thaha: doesn't matter
Apr 19 00:53:39 <prpplague> ds2: it's the makergear M2 with custom controller
Apr 19 00:53:43 <alan_o> thaha: stuff still goes to the console
Apr 19 00:53:59 <ds2> prpplague: what's the problem? I am on the M1
Apr 19 00:54:01 <thaha> ok...
Apr 19 00:54:34 <thaha> alan_o: is there an ubuntu image which i can reroute to the console only.?
Apr 19 00:55:06 <alan_o> thaha: I don't know
Apr 19 00:55:07 <ungureanuvladvic> jkridner|work: another question is that some development on a tablet combined with ubuntuTablet...i was looking at the cloud9 ide on the bone...maybe it can be made a bit generalized across all beagles but with a new app
Apr 19 00:55:23 <thaha> alan_o: I already tried out the image at https://wiki.ubuntu.com/ARM/OmapDesktopInstall and tried https://wiki.ubuntu.com/ARM/EditBootscr
Apr 19 00:55:35 <thaha> didnt work... same problem as Angstrom
Apr 19 00:55:54 <alan_o> thaha: If it were me, I'd try the *-beagleboard files on the site you linked
Apr 19 00:56:07 <alan_o> a lot of the new effort is going into the beaglebone
Apr 19 00:56:27 <alan_o> so if I see u-boot.img and u-boot-beagleboard.img, I'm going to think that the other is for the bone
Apr 19 00:57:01 <thaha> oh!
Apr 19 00:57:06 <thaha> let me try that now
Apr 19 00:58:54 <alan_o> ok, I'm out for a run. thaha if that doesn't work, not sure what to say. The guy who knows for sure isn't on right now.  Ask back in the morning when the europeans are on.
Apr 19 00:59:29 <alan_o> it could be debugged all the way down, no doubt, but as far as which combinations of the files on that web page to use, I can't say for sure.
Apr 19 01:00:07 <thaha> ok
Apr 19 01:00:08 <thaha> thanks
Apr 19 01:00:48 * ka6sox climbs into the transmitter...to warm up.
Apr 19 01:18:39 <prpplague> ds2: i am getting weird inconsistent behavior from the extractor
Apr 19 01:18:49 <prpplague> ds2: like it is pushing out to much
Apr 19 01:19:01 <prpplague> ds2: straight lines are good
Apr 19 01:19:15 <prpplague> ds2: curves seems to produces a super wide blob
Apr 19 01:19:33 <ds2> is this 3mm or 1.75mm filament?
Apr 19 01:19:45 <prpplague> ds2: 1.75
Apr 19 01:19:57 <ds2> PLA?
Apr 19 01:20:37 <prpplague> yea
Apr 19 01:21:02 <ds2> you checked to make sure there is no jams in the thermal break on the extruder?
Apr 19 01:21:07 <ds2> it should be above the heater area
Apr 19 01:21:13 <ds2> and that the temperature is right?
Apr 19 01:21:26 <prpplague> ds2: no jams, temp is at 212
Apr 19 01:22:23 <ds2> prpplague: did you see the reprap wiki for PLA? it recommends lower temps for some alloys and higher for others
Apr 19 01:23:10 <prpplague> ds2: no, i haven't seen that
Apr 19 01:23:20 <prpplague> ds2: simply because i am up against a deadline
Apr 19 01:23:25 <ds2> prpplague: reprap.org/wiki/PLA
Apr 19 01:23:30 <ds2> *nod*
Apr 19 01:23:43 <ds2> look at the heater settings area
Apr 19 01:24:02 <ds2> I donno what makergear ships with (I am going to cross this bridge soon)
