• [00:01:06] <jkridner|work> koen: you are up late.
  • [00:01:11] <jkridner|work> I hope not waiting on me.
  • [00:01:45] <koen> I'm up and waiting on you as well :)
  • [00:01:50] <jkridner|work> I think there are some concerns that your site doesn't make it very clear that Angstrom doesn't have any implied warranties.
  • [00:01:54] * koen is waiting for cairoperf to finish
  • [00:02:24] <jkridner|work> I have no ability to give you legal advice, either knowledge nor authority.
  • [00:03:33] <RobotGuy> I just plugged Beagle on the Trossen Robotics forums.
  • [00:04:25] <jkridner|work> Thanks RobotGuy.

  • [00:05:19] <RobotGuy> Well, the company who makes my current embedded Linux board is discontinuing it. :(
  • [00:07:48] <koen> cute
  • [00:08:07] <koen> cairo is about twice as fast with the 2.6.28rc4 kernel than with the 2.6.22 TI kernel
  • [00:08:16] <RobotGuy> I still like the linux boards I have, so don't get me wrong on that. :) In fact, I still plan to use them in my robot(s), possibly as auxiliary processors for dedicated tasks.
  • [00:08:49] <sakoman> RobotGuy: what boards have you been using up to now?
  • [00:08:51] <RobotGuy> I also have other areas where a Beagle Board would be gross over kill for what I want to do.
  • [00:09:35] <RobotGuy> sakoman: The Hammer Board by TinCanTools, and I am still tinkering with them, so have not stopped. I just seem to have toolchain problems frequently for some reason. :(
  • [00:10:42] <sakoman> RobotGuy: if size is an issue you could also use Gumstix Overo -- it has pwm and a/d available on the expansion connectors
  • [00:11:02] <RobotGuy> I won't use a Gumstix.
  • [00:11:16] <sakoman> bad experiences?
  • [00:11:43] <RobotGuy> Not for robotics anyway. I don't care for the way the boards are layed out, but that may not apply to the Verdex boards which I have not really looked at yet.
  • [00:12:04] <RobotGuy> sakoman: No bad experiences, since I have never actually used a Gumstix to date.
  • [00:12:10] <sakoman> Overo is much improved over Connex
  • [00:12:12] <RobotGuy> s/layed/laid/
  • [00:12:28] <sakoman> electrical or mechanical?
  • [00:12:33] <RobotGuy> I will have to look at Overo also then.
  • [00:12:41] <RobotGuy> sakoman: Mechanical mostly.
  • [00:12:51] <sakoman> Agreed - it really sucked
  • [00:13:12] <sakoman> Overo actually has 4 mounting holes
  • [00:13:38] <RobotGuy> I really like the layout and features and speed of the Beagle Board, so I think that is the way I am heading for now, along with Hammer.
  • [00:14:03] <sakoman> And there are plastic snap in "thingies" for mounting the motherboard
  • [00:14:10] <RobotGuy> Hmmmmmm
  • [00:14:40] <RobotGuy> A Beagle Board could almost fit into my smallest robot designs.
  • [00:14:50] <sakoman> http://gumstix.net/overo
  • [00:15:01] <sakoman> picture for size
  • [00:15:35] <RobotGuy> I don't want to load the channel with discussion of things other than Beagle though.
  • [00:15:57] <sakoman> ok
  • [00:16:57] <koen> cairo perf comparing kernels: http://dominion.thruhere.net/koen/OE/cairo-perf-diff-kernel.txt
  • [00:17:03] <ds2> does the overo still use 0-80 fasteners?
  • [00:18:08] <sakoman> ds2: you could use those or the plastic thingies
  • [00:18:18] <sakoman> I'll try to get a picture
  • [00:18:46] <jkridner|work> koen: any questions before I shut down for the night.
  • [00:18:49] <ds2> sakoman: 0-80 is not a easy fastener to find
  • [00:20:05] <koen> jkridner|work: not really
  • [00:21:03] <Crofton> there's a link to a place that makes it easy to get that stuff
  • [00:21:19] <Crofton> sakoman, gave it to me, it could be on the gumstix site
  • [00:21:25] <ds2> not saying it is impossible to find; there is a local speciality fastener place that sells it
  • [00:21:53] <sakoman> ds2: a picture of the plastic thingies for mounting without screws & spacers:
  • [00:21:59] <ds2> but that place keeps traditional business hours that has limited overlap with my work hours ;)
  • [00:22:04] <jkridner|work> oh, koen: you probably want to mention to use "DSP/BIOS Link for Linux 1.60.00" and not the "Porting Kit" version at https://www-a.ti.com/downloads/sds_support/targetcontent/link/link_1_60/index.html

  • [00:24:46] <ds2> moving away from the hirose connectors is a start

  • [00:26:59] <koen> watching Crofton struggle with the screws was pretty funny
  • [00:27:04] <ds2> sakoman: I also do machining of small stuff so I am more used to them
  • [00:27:06] <sakoman> Or maybe I'm just an old man with limited dexterity ;-)
  • [00:27:21] <ds2> a good tweezer worth its weight in rhodium ;)
  • [00:27:57] <sakoman> heh, lots of tweezers here. maybe because I can't see the damn things either!
  • [00:28:13] <RobotGuy> It's the mechanical aspects that put me off from trying a Gumstix.
  • [00:28:13] <ds2> one of those lighted magnifiers help a lot

  • [00:32:11] * koen realizes he is working in his hometown on monday
  • [00:32:23] <ds2> sakoman: You have no idea how close I am to doing that... but a shortage of clients is killing things :(
  • [00:33:22] <ds2> infact to do the 3D scanner I have to run the camera on x86 and talk to the beagle via USBnet :(
  • [00:33:28] <sakoman> ds2: yeah, it would be good to have someone to pick up the expenses
  • [00:34:08] <ds2> sakoman: not just that... if this keeps up, I'll be living in a national forest in my truck :(

  • [00:38:48] <ds2> koen: how do they handle the point clouds?
  • [00:40:05] <koen> it uses null-space error mimimization, so it extracts features into a subspace to work on

  • [01:08:40] <sakoman> cooler the last couple of days though
  • [01:08:58] <ds2> but come jan, don't you dip below 32?

  • [05:55:33] <ds2> rebuild the kernel
  • [05:55:34] <ds2> =)
  • [05:56:01] <geckosenator> fuck
  • [05:56:03] <geckosenator> heh
  • [05:56:06] <ds2> I think the later kernels have a menuconfig item, otherwise you have to edit the file in drivers/video/omap
  • [05:56:07] <geckosenator> are you serious?
  • [05:56:17] <geckosenator> I can't do it as a kernel parameter?
  • [05:56:32] <ds2> Pretty much... unless the bootcommandline mode enhancements made it into the kernel
  • [05:56:39] <ds2> check the source just in case
  • [05:56:41] <geckosenator> ok
  • [05:57:07] <geckosenator> well thanks, that explained a lot
  • [05:57:29] <ds2> heh.. it is not that painful to edit the file and rebuild; I am used to it
  • [05:57:41] <geckosenator> right, I didn't build the kernel ever though
  • [05:57:51] <ds2> Oh, that does make it harder
  • [05:57:58] <geckosenator> right, but only once
  • [05:58:03] <geckosenator> I'm going to have to build it anyway
  • [05:58:22] <ds2> u using the angstrom kernel?
  • [05:58:33] <geckosenator> yes
  • [05:58:45] <ds2> that probally has the commandline patch
  • [05:59:07] <ds2> check the irclogs, I think either koen or mru explained how to use it before
  • [05:59:17] <geckosenator> I might need to download it again
  • [05:59:22] <geckosenator> I think I was doing it right
  • [05:59:35] <geckosenator> well, I was doing it the way any other framebuffer driver works
  • [05:59:51] <ds2> welcome to omapfb
  • [05:59:53] <ds2> ;)
  • [05:59:56] <geckosenator> heh
  • [06:00:06] <geckosenator> I got some 3d goggles
  • [06:00:16] <ds2> I remember those those days when I first started looking at it
  • [06:00:19] <geckosenator> they run off usb power and use oled lcd displays, 800x600 res
  • [06:00:36] <geckosenator> and they run at 60hz and give 30hz to each eye and switch between right and left
  • [06:00:40] <ds2> how do you generate the sync/alternating signals for them?
  • [06:00:43] <geckosenator> I want to make it work with opengl with right and left buffers
  • [06:01:11] <ds2> I know they used to sell them back when the Voodoo cards were a big deal but those cards had a special connector for them
  • [06:01:16] <geckosenator> ds2: they are vga, but if you run at 60hz, it uses every other fram for each eye
  • [06:01:28] <geckosenator> so you don't need special cards or connectors
  • [06:01:42] <geckosenator> just a way to tell the driver that every other frame is a different buffer for opengl
  • [06:01:48] <geckosenator> so it can do 3d
  • [06:01:52] <ds2> okay, how do you get software to generate those signals then?
  • [06:02:01] <geckosenator> the vga ones?
  • [06:02:07] <ds2> yeah
  • [06:02:10] <geckosenator> I'm not
  • [06:02:16] <geckosenator> I'm doing hdmi->vga
  • [06:02:30] <ds2> so it is just 2d for you?
  • [06:02:34] <geckosenator> well no
  • [06:02:39] <geckosenator> I hope to run the hdmi at 60hz
  • [06:03:04] <geckosenator> so it will take odd frames for left and even frames for right eye
  • [06:03:09] <ds2> but how do you get the omapfb to generate L/R images?
  • [06:03:12] <geckosenator> then when you render in your opengl program, you render twice
  • [06:03:23] <ds2> w/o that you get 2D only
  • [06:03:23] <geckosenator> and you glTranslate a little to the side
  • [06:03:25] <geckosenator> yeah
  • [06:03:31] <geckosenator> well that is the thing
  • [06:03:47] <geckosenator> the omapfb needs to work with opengl.. opengl has support for left and right buffers already
  • [06:03:54] <ds2> ah
  • [06:04:05] <geckosenator> so there are already opengl programs that will work
  • [06:04:06] <ds2> have fun getting that to work rightt
  • [06:04:09] <geckosenator> heh
  • [06:04:17] <geckosenator> I'm going to have fun doing hdmi to vga
  • [06:04:26] <geckosenator> one board does hdmi to parallel
  • [06:04:32] <geckosenator> another does parallel to vga
  • [06:04:45] <geckosenator> then there is 1.8v parallel to 3.3v parallel (once revc is out)
  • [06:04:49] <ds2> hdmi too VGA is pretty easy
  • [06:04:55] <ds2> hdmi to VGA
  • [06:04:57] <geckosenator> it's not hard
  • [06:05:11] <geckosenator> the nice part is once revC is out, it will be parallel to vga
  • [06:05:16] <geckosenator> and save a lot of power
  • [06:06:03] <ds2> indeed
  • [06:06:17] <geckosenator> but for now hdmi to parallel is convenient
  • [06:06:32] <geckosenator> I'm also doing parallel breakouts for psp displays
  • [06:06:54] <ds2> oh that's nice
  • [06:06:57] <geckosenator> it might be nicer instead of having the dvi framer, just have a connector
  • [06:07:09] <geckosenator> then plug little boards on it that output whatever you want
  • [06:07:23] <geckosenator> like LVDS, hdmi, parallel (3.3v), or vga
  • [06:07:46] <geckosenator> but I guess its' ok if hdmi is always there
  • [06:08:38] <geckosenator> I would love it if someone would review my schematic and layout before I try to get the pcbs made though...
  • [06:08:50] <geckosenator> I'm not really experienced in this stuff that much so I might screw it all up

  • [06:10:27] <ds2> how many are you making?
  • [06:10:35] <geckosenator> I was going to use batch-pcb
  • [06:10:49] <geckosenator> so I don't know I might make 2 of each
  • [06:11:12] <geckosenator> I would make these, then test them and if they are working before making too many
  • [06:11:25] <ds2> how much do they want for the 4layers?
  • [06:11:35] <geckosenator> well, it's $2.50 per sq inch
  • [06:11:52] <geckosenator> and the boards are something like 2-3 sq inches
  • [06:11:56] <ds2> thought that was 2layers only
  • [06:12:05] <geckosenator> I'm not sure then
  • [06:12:12] <geckosenator> it says 2 or 4 layer, and $2.50
  • [06:12:24] <ds2> must be new... 4L is nice
  • [06:12:29] <geckosenator> yeah
  • [06:12:33] <geckosenator> I'm doing 1 ground plane
  • [06:12:35] <geckosenator> then 3 signal
  • [06:12:51] <geckosenator> I could probably do it all on 2 layers
  • [06:12:57] <geckosenator> but it's easier to route this way
  • [06:13:09] <ds2> 4L is nice, power + gnd planes
  • [06:13:25] <geckosenator> what is wrong with gnd and 3 signal?
  • [06:13:27] <ds2> is it still $10 setup?
  • [06:13:35] <geckosenator> I hope so :-P
  • [06:13:50] <ds2> less noise and easier to route with a power + gnd plane
  • [06:14:02] <ds2> keeps the impendence of the power lower

  • [08:52:37] <koen> there's something wrong if your hub powers the beagle while it's connected on the host port

  • [09:01:08] <kulve> but they both work ok
  • [09:01:25] <kulve> (and all the hubs I'm using are quite new)
  • [09:01:34] <Beagle3> so can it be the adapter on the host cable of the usb hub the reason why the hub powers the beagleboard ?
  • [09:02:30] <Beagle3> so when i think right i can not power the beagle with the usb mini port when i want to use usb devices ?
  • [09:03:23] <koen> if you connect a powerplug it should cut of the +5v from usb
  • [09:03:26] <kulve> yeah, that's how it generally works. If your beagle is the usb master, then it feeds the power to the devices (or the hub does). If the beagle is the usb slave, then somebody else can feed the power to the beagle via usb
  • [09:04:34] <koen> kulve: it seems that if you want fast X, 2.6.28rcX + xf86-video-omapfb is the answer

  • [09:06:33] <kulve> that's not yet "fast X", it only adds XV to the X. I would be interested in accelerating the X (xrender?) using the sgx. But that seems to be quite untrivial. Doing it on top of opengl es 2 seems to be very unefficient and I guess we don't have access to the hw on a lower level

  • [09:18:10] <tomba> geckosenator: well, if reading from ram is fast =) usually ram read/write is still the bottleneck in many cases
  • [09:18:32] <kulve> we started creating an X driver on top openg gl es but we faced some bugs in the opengl es stack (and the hw) and some technical difficulties..
  • [09:18:54] <tomba> a bad thing in this one is, of course, that displaying anything on the LCD uses ram bandwidth all the time

  • [09:19:56] <Beagle3> can anybody plz tell me what kind of usb hub he uses on beagle ? plz

  • [09:34:11] <tomba> well, what sgx does is basically modify memory, be it openvg or opengl es. so with proper integration it should work on top of anything. the example code from IMG probably just gives quite limited options how to use it

  • [09:34:47] <kulve> tomba: yeah, "with proper integration"
  • [09:35:34] <kulve> i.e. X.Org driver that handles it. Like the nvidia and ati do for their card. But they have access to the hw directly, we have only opengl es, which makes it a bit harder
  • [09:36:39] <kulve> if the sgx drivers will be open sourced at some point, maybe the x driver could be done using it directly. Depends what the kernel driver does and how it's documented I guess..
  • [09:37:46] <kulve> the img.tec. SDK does have some 2d user space libraries as well, that could provide e.g. blit operations etc. which already would be quite nice. But I think I haven't seen any API documentation for it

  • [09:38:58] <kulve> I understood that with the way X and opengl es 2 work, you need to do too much copying back and worth which makes it reaaally slow.
  • [09:39:32] <kulve> but I have be afk for couple of hours so we can continue on the topic later :)
  • [09:39:48] <tomba> but that's the integration to X (one version at least), not opengl itself.
  • [09:41:24] <tomba> there's opengl/openvg that basically just draw to any memory area pointed to them. then there's the windowing system integration, in X's case (the implementation you mentioned) it includes drawing to a backbuffer and copying that buffer to the X window
  • [09:42:17] <tomba> the integration could be done in other ways also. for example there's also a "no backbuffer framebuffer" implementation that draws directly to fb memory
  • [09:44:23] <kulve> tomba: how familiar you are with opengl es 2? I'm just started to study it because I'm interested in this X integration. But I don't probably have enough time (nor skills) to actually accomplish anything.. :)
  • [09:44:48] <zuh> koen: Pretty interesting numbers :D
  • [09:46:33] <tomba> kulve: no very familiar. I have ported the drivers it to our HW, so I know something about the stuff (like integration to windowing system), but not much about the upper layers. and I've never coded a single opengl application =)
  • [09:47:17] <kulve> tomba: well, I think for this X integration you know enough then, I guess it doesn't really touch most of the opengl es 2's functionality

  • [11:55:20] <koen> hey jkridner & ldesnogu_
  • [11:55:38] <jkridner> what is new today?
  • [11:56:05] <zuh> koen: I wonder what they have done to make cairo alpha test cases such Epic Failures... I mean, I did observe a significant performance drop when I enabled EXA callbacks which would just fall back, but nothing like the numbers you got...
  • [11:57:05] <jkridner> 1000 people on the mailing list and no one is taking a $100/hour consulting job?
  • [11:58:47] <ldesnogu_> perhaps someone answered privately?

  • [12:01:11] <koen> zuh: I suspect an older pixman
  • [12:01:27] <koen> zuh: pixman got an optimization for alpha values recently
  • [12:01:34] <koen> zuh: and all speedups are in rgba
  • [12:01:45] <koen> zuh: but that's just guesswork
  • [12:02:16] <zuh> Could be, yeah
  • [12:03:21] <zuh> That would explain the lack of speedups of any kind too, I suppose
  • [12:04:12] <zuh> hm, would preloading the newer pixman lib mask the symbols from the server binary?-)
  • [12:04:23] <zuh> probably not
  • [12:04:26] * koen has no idea
  • [12:04:50] <koen> I'm dissappointed that imgtec only added eglx
  • [12:05:12] <koen> but I guess they target phones and pdas, which usually only have fullscreen apps
  • [12:06:20] <ldesnogu_> koen, can't eglx be integrated with standard X servers?
  • [12:06:57] <koen> 12:51 < koen> zuh: I wonder if imgtec can be convinced to make a Xorg module for the eglx stuff
  • [12:07:05] <ldesnogu_> oops sorry :)
  • [12:07:24] <ldesnogu_> but your last remark seemed to imply eglx => fullscreen
  • [12:08:07] <koen> I didn't mean to imply it
  • [12:08:17] <koen> but all apps have to speak eglx
  • [12:08:56] <koen> I'd like to have an Xorg module that translated glx into the relevant gles api
  • [12:09:13] <ldesnogu_> that will be difficult to achieve...
  • [12:09:14] <koen> that wouldn't have IP and can be open source
  • [12:10:21] <koen> most stuff I run needs either XV or Xrender (through cairo)
  • [12:10:50] <koen> and gtk based apps seem to be moving to clutter
  • [12:10:59] <koen> and a have clutter somewhat working with Xsgx
  • [12:11:16] <koen> gnome-games 2.25.1 uses clutter for the card animations :)
  • [12:13:20] <koen> I don't if a quake1 and quake2 port to gles exists
  • [12:13:39] <zuh> koen: Come on, if everything worked like on the desktop the whole mobile industry would collapse since there would be no need to rewrite every program in a custom, incompatible way anymore. Think of the poor developers who'd be out of work!
  • [12:13:58] <koen> :)
  • [12:14:29] <koen> if intel succeeds all the cross-compile people (OE, scratchbox) will be out of a job as well :)
  • [12:15:48] <zuh> koen: I suppose that would be a bad thing?-)
  • [12:16:02] <zuh> I'm personally not sure it would :)
  • [12:16:23] <koen> I'd like people to fix their buildsystems :)
  • [12:16:32] <ldesnogu_> I'd like Intel to collapse
  • [12:16:34] <ldesnogu_> :)
  • [12:16:36] <koen> that would be a much better way to lose a x-compile job :)

  • [12:54:47] <Beagle1> ;-)
  • [12:54:53] <mru> I figured as much
  • [12:54:53] <Beagle1> thats all ;-)
  • [12:55:41] <ldesnogu_> Beagle1, something like this? https://www.partsdata.de/USB_cable_with_miniB_plug_Epson_Kodak_Samsung_5m__gb_CU-B07-50.html
  • [12:55:49] <ldesnogu_> why don't you try google ? :)
  • [12:56:52] * FuL|OUT is now known as fulgas
  • [12:57:04] <Beagle1> thats not the same cable
  • [12:57:22] <Beagle1> i need it to conect the usb hub
  • [12:57:58] <kulve> that's not actually even the mini-b that can be used with beagle, that's something even more rare..
  • [12:58:17] <ldesnogu_> Beagle1, the site I linked to has many USB cables
  • [12:58:25] <kulve> Beagle1: genderchanger adapters are more common
  • [12:58:48] <kulve> so you may use it with the mini-b -cable too..
  • [12:59:12] <Beagle1> what are gendercharger adapters ?
  • [12:59:41] <kulve> male A -> female A
  • [12:59:57] <kulve> at least that's what I was trying to say..
  • [13:00:55] <Beagle1> so how did you conect your usb hub on beagle ?

  • [13:01:11] <Beagle1> can you write me down your cable settings
  • [13:03:06] <kulve> I have: beagle -> mini-b<->female A -> male A<->male B -> hub
  • [13:03:27] <kulve> actually I have too this:
  • [13:03:50] <kulve> beagle -> mini-b<->male A -> gender changer -> male A<->male B -> hub

  • [13:05:47] <Beagle1> ok
  • [13:06:26] <Beagle1> so i need this minib to female a
  • [13:07:56] <kulve> I suggest that you find mini-b <-> anything and then a proper adapter for the anything. Because the mini-b is the rare thing here

  • [13:11:26] <Beagle1> what is the difference between mini b and min a ?
  • [13:12:08] <mru> sort of the same as between normal b and normal a
  • [13:12:11] * shriram (i=3d5fc3cd@gateway/web/ajax/mibbit.com/x-9e310e831b1a876c) Quit ("http://www.mibbit.com ajax IRC Client")
  • [13:12:18] <mru> A connects to a host, B to a gadget
  • [13:13:13] <Beagle1> so a mini b can not be connected in a mini a right ?
  • [13:13:22] <Beagle1> because of size etc. ?
  • [13:13:24] <kulve> it can
  • [13:13:49] <Beagle1> so mini a can be connectedin beagle ?
  • [13:14:24] <kulve> hmm.. did I mix those again..
  • [13:14:36] <kulve> check the wiki page and the table "Miniplug/Microplug"
  • [13:14:40] <kulve> it tells you the difference
  • [13:15:01] <kulve> you need "Type A: connected to Ground"
  • [13:15:50] <Beagle1> what i want to know if it is possible to plug in a mini a in beagle ... so is the size the same and would fit ?
  • [13:15:54] <kulve> so in my earlier comments I mixed them, sorry
  • [13:15:55] <Beagle1> so if not
  • [13:16:12] <Beagle1> i have a mini b -> usb a
  • [13:16:28] <kulve> physically you can connect both mini-a and mini-b but only the mini-a will tell beagle to act as a usb host
  • [13:17:12] <kulve> http://elinux.org/BeagleBoard#OTG
  • [13:17:18] <kulve> check the wikipedia and that one
  • [13:18:04] <Beagle1> ok so i have to plug in a mini a in beagle right ?
  • [13:18:16] <kulve> right
  • [13:18:21] <Beagle1> ;-)
  • [13:18:50] <Beagle1> but why did you write that you connected a mini b ?
  • [13:18:58] <Beagle1> i am little bit confused ;-)
  • [13:19:36] <Beagle1> you wrote: beagle -> mini-b<->male A -> gender changer -> male A<->male B -> hub
  • [13:19:44] <kulve> because I (again) forgot which was which, sorry about that
  • [13:19:58] <kulve> in those I meant mini-a although I wrote mini-b..
  • [13:20:00] <Beagle1> ah ok it was a mistake at first ok
  • [13:20:01] <Beagle1> np
  • [13:21:30] <Beagle1> you know a shop where i can buy those mini A to male A cable ?
  • [13:22:09] <kulve> nope, sorry. I didn't find one in finland so our sales guy brought a few from his Asian trip
  • [13:22:22] <Beagle1> so that i understand it right ... a mini b cable is so used to power the beagle with the usb connector right ?
  • [13:22:40] <Ikarus> and for the beagle to operate in device mode
  • [13:22:41] <kulve> the elinux.org has a link to some shop, but I don't know how easy it is to order one from there
  • [13:23:04] <Beagle1> ok
  • [13:23:47] <kulve> Beagle1: yeah, the beagle acts as a usb device then and can get the power from the usb host (usb hub or PC). On the slave mode a linux computer can act as a network device or a usb mass storage, etc
  • [13:24:14] <kulve> s,usb device,usb slave device,
  • [13:27:26] <Beagle1> ok thx
  • [13:27:31] <Beagle1> i am learning ;-)

  • [13:52:38] <Beagle1> hmmmm
  • [13:53:33] <shriramv> im not sure if there is a patch. but it can be done - you need to put dss and lcd stuff in there
  • [13:54:40] <j24> shriramv: jkridner I've hear that someone acheive it
  • [13:54:53] <j24> maybe their is a patch
  • [13:55:08] <j24> I'm also looking for CDC ECM support
  • [13:55:18] <j24> maybe some have
  • [13:55:18] <shriramv> i know a few ppl have done it for thier custom boards
  • [13:55:40] <shriramv> but im not sure if they have posted a patch somewhere

  • [13:56:12] <jkridner> in that patch set, there is a beagleboard.org logo for u-boot.
  • [13:56:25] <jkridner> it was against an older u-boot.
  • [13:56:57] <jkridner> I know some folks are working on CDC support for u-boot, but I haven't seen the activity in specific.
  • [13:57:25] <j24> jkridner: u-boot already support CDC ACM

  • [13:58:46] <jkridner> j24: I believe that no one has pushed patches for USB support on OMAP3. I've heard *talk*, but I haven't heard any confirmation it has been done.
  • [13:58:50] <jkridner> maybe others have?
  • [13:59:19] <jkridner> I look at http://git.denx.de/?p=u-boot/u-boot-arm.git;a=shortlog;h=refs/heads/omap3 for the latest omap3 u-boot.
  • [13:59:35] <j24> jkridner: ha my tree
  • [13:59:38] <jkridner> though sakoman has many interesting patches I like.

  • [14:03:29] <j24> jkridner: maybe an ftp or a site where I can download all patch collection
  • [14:03:59] <j24> jkridner: old and new u-boot
  • [14:04:46] <jkridner> not really: there are some old u-boots at http://code.google.com/p/beagleboard/downloads/list
  • [14:05:02] <jkridner> the 1.3.3 does include a splashscreen.
  • [14:05:20] <jkridner> specifically http://beagleboard.googlecode.com/files/u-boot_beagle_revb.tar.gz includes a splashscreen.
  • [14:06:39] <jkridner> there are several patches sitting out on the mailing list archives, but sakoman and dirk2 have submitted the important ones and they are merged into your tree.
  • [14:06:59] <jkridner> I don't know where people are staging the USB patches. :(

  • [17:09:30] <koen> 2.6.26 doesn't have gpio-keys support for the user button
  • [17:09:48] <koen> it was introduced somewhere near 2.6.27
  • [17:10:17] <koen> if you're using the 2.6.28rc kernel for svideo support, that should have gpio-keys support for the user putton

  • [17:16:16] <Fl1pFl0p> so when i get new kernel .. how do i access it?
  • [17:16:22] <Fl1pFl0p> is it a /dev/ ?
  • [17:17:02] <koen> /dev/input/event<number> iirc
  • [17:17:18] * koen headdesks
  • [17:17:44] <koen> keys-gpio isn't turned on
  • [17:17:44] * koen turns it on
  • [17:18:39] <koen> Fl1pFl0p: try http://dominion.thruhere.net/koen/OE/uImage-2.6.27+2.6.28-rc4+r0+gitr5ecf98b76fa95078277c9037bb01640fd3de5e2c-r0-beagleboard.bin
  • [17:18:41] <Fl1pFl0p> you have to turn on gpio in mux boot screen right?
  • [17:19:45] <koen> ?
  • [17:20:27] <Fl1pFl0p> i read something that the multiplexer had to be configured for gpio
  • [17:21:00] <koen> that's if you want to use the GPIOs on the expansion port
  • [17:21:24] <koen> iirc it's configured for i2c by default
  • [17:22:40] <Fl1pFl0p> i may end up doing that, but at a minimum i need user button to work.
  • [17:23:14] <Fl1pFl0p> thanks koen .. im going to try this kernel

  • [19:27:32] <FlipFlop> hell six pack
  • [19:29:52] <FlipFlop> vegar .. i can say they are kinda weak but i have a list of modules some where
  • [19:29:55] <FlipFlop> one sec
  • [19:30:39] <FlipFlop> http://www.linuxwireless.org/en/users/Drivers/zd1211rw/devices
  • [19:30:54] <FlipFlop> that is a list of the supported devices for zd1211rw
  • [19:31:02] <FlipFlop> you will want a powered hub
  • [19:31:17] <FlipFlop> if you use full power it will cause usb port to crash
  • [19:31:56] <FlipFlop> you will notice alot of companies use the same chip set
  • [19:32:31] <FlipFlop> so i have 2 usb wifi modules from different companies, both have the same hex values that define the device
  • [19:33:01] <FlipFlop> mine have "0ace 1211"
  • [19:33:40] <Vegar> thanks, I didn't know about that site
  • [19:33:58] <Vegar> is zd1211rw the only driver available on ARM?

  • [19:54:17] <FlipFlop> i guess some company will have there own driver
  • [19:54:28] <FlipFlop> that will support all the features of the device
  • [19:54:45] <FlipFlop> the zd1211rw may not support every feature of the wifi device
  • [19:55:11] <FlipFlop> say you need a certain level of encryption, zd1211rw may not support it
  • [19:57:13] <Vegar> ok
  • [19:58:33] <Vegar> what about the SD interface? what card class should I buy to get the best performance?
  • [19:59:33] <FlipFlop> never used it
  • [19:59:47] <FlipFlop> not sure if it uses the same chipsets or not
  • [20:01:06] <koen> there are atheros drivers for SDIO, but I have no experience with them
  • [20:01:17] <koen> AIUI pandora and overo have sdio wifi
  • [20:05:20] <Vegar> I was thinking about memory cards
  • [20:05:34] <Vegar> (compiling a shopping list)
  • [20:05:48] <koen> my 4gb sandisk SDHC works great
  • [20:05:57] <koen> it even came with an usb card reader
  • [20:06:09] <koen> 8gb sandisk sdhc also works
  • [20:06:30] <Vegar> yes, but the cards have different speed classes
  • [20:07:04] <Vegar> so I was wondering if I should invest in a high-speed card or if a cheap one is good enough
  • [20:07:26] <koen> I get 15MB/s on my snadisk extreme 3 (or 4) card
  • [20:07:48] <koen> which is the speed that card advertises as max speed
  • [20:08:03] <Vegar> so the SD interface isn't that slow
  • [20:08:26] <Vegar> "Kingston Secure Digital 8GB SDHC, Class6, SD2.0 specification"
  • [20:08:35] <Vegar> I'll try that
  • [20:08:49] <Ikarus> class 6 aren't the fastest
  • [20:10:06] <Vegar> it's the fastest from this shop
  • [20:11:28] <geist> 15MB/sec is pretty good for SD
  • [20:11:32] <geist> highest i've seen is 18 or 19
  • [20:11:43] <geist> which is approaching the theoretical limit of SD

  • [20:23:26] <sakoman> koen: r6 works great on overo too
  • [20:23:37] <sakoman> just been playing with vncviewer
  • [20:23:54] <koen> sakoman: I'm happy that some musb patches got applied in mainline
  • [20:23:55] <sakoman> pretty funny driving my server from the overo
  • [20:24:22] <sakoman> koen: yeah, a bunch of the ones I have in my local patch set finally got applied
  • [20:24:35] <koen> I'm driving the evm and beagle from my iphone
  • [20:24:46] <sakoman> the ones that allow my KVM to work are the most welcome
  • [20:24:56] <koen> for the evm it's pretty neat, for the beagle it's a gimmick
  • [20:26:36] <sakoman> the whole desktop thing on omap3 is a bit of a gimmick. it is so easy to bring the system to its knees just doing normal desktop stuff
  • [20:26:58] <Vegar> really?
  • [20:27:02] <koen> the extra 128MB ram on my superbeagle makes a big difference
  • [20:27:31] <koen> but anything needing xrender will be slow
  • [20:27:37] <sakoman> koen: yeah, all overos are 256mb too, but I can still crash things easily if firefox is in the equation
  • [20:27:40] <koen> since X has no accel for that
  • [20:28:05] <koen> I don't need an ARM system for that
  • [20:28:13] <sakoman> agreed
  • [20:28:27] <sakoman> but desktop = browser for most folks
  • [20:28:32] <koen> ff and thunderbird pretty much the memory manager on my mac as well

  • [20:29:03] <sakoman> knew exactly what you meant

  • [20:30:49] <koen> it's past 8pm, so no caffeine for me
  • [20:30:58] <sakoman> did you play any more with udumpty-image?
  • [20:31:28] <koen> no, but I did look into gdm's session management
  • [20:31:59] <koen> it expects the stuff OE crams into /etc/X11/Xsession.d in /etc/X11/xinit
  • [20:32:37] <sakoman> ah, that would explain why nothing much happens when I launched it by hand
  • [20:32:45] <koen> gdm needs some extra love in the postinst to create the 'gdm' user, setup pam, etc

  • [20:39:15] <koen> insecure, but works real nice
  • [20:39:26] <sakoman> yeah, I saw that checkin
  • [20:39:28] <Vegar> so ram is the limiting factor on the beagle?
  • [20:40:05] <koen> that and no real display drivers at the moment
  • [20:40:31] <koen> zuh's awesome XV driver makes watching movies in X bearable
  • [20:43:29] <sakoman> koen: not familiar with that
  • [20:43:42] <sakoman> is it in OE now?
  • [20:43:44] <koen> yes
  • [20:43:51] <koen> xf86-video-omapfb
  • [20:44:11] <koen> works real nice with DSS1 and will need a little tweaking for DSS2
  • [20:44:20] <sakoman> so just add that to the image?
  • [20:44:35] <koen> and change 'fbdev' to 'omapfb' in xorg.conf
  • [20:44:48] <sakoman> any special kernel requirements?
  • [20:45:02] <koen> a decent dma size
  • [20:45:15] <sakoman> 6MB will work?
  • [20:45:28] <koen> it should
  • [20:45:45] <koen> video=omapfb:vram:2M,vram:4M in bootargs
  • [20:46:08] <koen> and check if you have a /dev/fb1, the udev coldplug cache might get in the way
  • [20:46:12] <sakoman> is that what you use?
  • [20:46:17] <koen> if it does, rm /etc/udev.tar
  • [20:46:22] <koen> yes, that's what I use
  • [20:46:24] <koen> well
  • [20:46:42] <koen> 14MB for dma, but that's for DSS2, it needs a bit more for svideo and stuff
  • [20:47:01] <koen> I think xf86-video-omapfb is default for beagle in OE nowadays
  • [20:47:53] <Vegar> isn't there a neon accelerated mplayer?
  • [20:48:50] <koen> there is
  • [20:49:21] * koen should put the omapfb vo in OE

  • [22:03:06] <Vegar> Is it a realistic goal?
  • [22:03:16] <koen> Vegar: you mean 'run angstrom', not 'run OE'

  • [23:29:35] <TheUni> felipec: with a null modem adapter
  • [23:29:51] <TheUni> but my header looks different than the pictures i'm seeing on the net
  • [23:30:09] <TheUni> pins seem to go 1-1, 2-6, 3-7, etc
  • [23:31:17] <felipec> TheUni: http://elinux.org/BeagleBoard#RS232
  • [23:32:27] <TheUni> felipec: are most standard cables not suited? i have a handful of these, but they're all made up the same way
  • [23:33:17] <felipec> TheUni: I had a bunch of those from TI, they didn't work, most PC's have the ones that the beagle can use
  • [23:33:41] <TheUni> ugh
  • [23:34:18] <TheUni> felipec: any danger in trying to resolder them?
  • [23:34:28] <nmq> why don't you just make one? ribbon on one end, DB9 on the other, costs only a few bucks and minutes
  • [23:34:31] <TheUni> can i screw anything up if i get the pinout wrong?
  • [23:34:44] <TheUni> nmq: about to...
  • [23:35:11] <nmq> I actually made mine wrong twice and the beagle still works
  • [23:35:16] <nmq> :P
  • [23:35:32] <TheUni> *sigh*
  • [23:35:39] * TheUni breaks out his $4 soldering iron
  • [23:35:42] <TheUni> this should go well...
  • [23:35:43] <nmq> just follow the datasheet for the recommended cable in digikey
  • [23:36:20] <felipec> just google for IDC10
  • [23:36:54] <TheUni> oh, that looks easy enough...
  • [23:36:59] <TheUni> http://www.pccables.com/07120.htm ?
  • [23:37:24] <nmq> haha, no, that's my first wrong attempt
  • [23:37:40] <TheUni> ?
  • [23:37:58] <nmq> you would still need the null modem cable
  • [23:38:08] <TheUni> yea, i have an adapter
  • [23:38:25] <nmq> oh
  • [23:38:46] <nmq> what I did was get a female end and follow the wiring for this one: http://www.usa-assmann.com/Specs/AK143-3-R.pdf
  • [23:39:13] <nmq> that's the recommended cable
  • [23:39:51] <nmq> IDC10+null modem in one :)
  • [23:40:58] <TheUni> heh
  • [23:41:05] <TheUni> that'll give me a headache trying not to screw up
  • [23:41:08] <TheUni> i'll just use my adapter
  • [23:41:58] <gcohler> Just jumping into this one late... The IDC10 to DB9 is normally a straight thru 1-1, 2-2, 3-3, etc. Then the Nul Modem is in the F-F cable attached to it.
  • [23:42:43] <gcohler> But if you have the nulmodem in the IDC-DB9, then you could use a straight thru F-F cable with it.
  • [23:44:30] <nmq> do all null modem cables work? I know there is at least 3 variatons..
  • [23:45:29] <gcohler> There are only three pins that Beagleboard uses -- tx, rx, signal ground. So I think any nul modem should work. The differences are usually around other pins.

  • [23:47:51] <sakoman> RobotGuy: read the bold italic notes in the Gumstix setup instructions -- it covers this
  • [23:49:52] <sakoman> RobotGuy: Also you won't need to set up more than one OE
  • [23:50:17] <sakoman> if you setup the gumstix oe you get the upstream one for free
  • [23:50:36] <RobotGuy> I'm confused
  • [23:50:51] <sakoman> just checkout the org.openembedded.dev branch instead of the overo branch
  • [23:51:00] <sakoman> RobotGuy: about?
  • [23:51:13] <RobotGuy> OK, I do that when setting up for Beagle.
  • [23:52:45] <sakoman> No, what I mean is that when you checkout the overo branch of oe you also get org.opnembedded.dev since it tracks org.openembedded.dev
  • [23:52:47] <RobotGuy> There must need to be some changes to the local.conf and profile files for each, right?
  • [23:53:47] <sakoman> yes, just change build/conf/auto.conf to set the machine to beagleboard instead of overo
  • [23:54:07] <RobotGuy> There is no build dir for Beagle
  • [23:54:19] <sakoman> don't need one
  • [23:54:24] <sakoman> they share nicely
  • [23:54:48] <RobotGuy> But how do I have it so I can work with either at will?

  • [23:54:55] <sakoman> I regularly build for beagle, evm, and overo using the same oe repo
  • [23:55:26] <sakoman> just change machine setting in build/conf/auto.conf
  • [23:56:25] <sakoman> most packages are shared since the machines are the same architecture
  • [23:56:48] <sakoman> things that are machine specific will show up in the right subdirectory in deploy
  • [23:57:07] <sakoman> The OE guys did a great job making this all work
  • [23:57:55] <nmq> How can I make a filesystem (directory tree)? I have only seen koen's 8mb image, but I want something bigger and with different stuff on it. Any pointers on where to look?
