  • [00:47:08] <dcordes> now I will try out different distros and older kernel. maybe the module is broken or so

  • [02:44:48] <banderson> dcordes: ya still here.
  • [02:44:51] <dcordes> also here I do not see anything from the beagle board in "terraterm"
  • [02:45:28] <banderson> dcordes: can you do the same loopback trick for xp?
  • [02:46:30] <dcordes> yes. What does it mean when I connect to the beagle usb to my desktop usb and it doesn' turn on and the power led only flickers?
  • [02:46:42] <dcordes> (and no other led)
  • [02:46:59] <banderson> not sure never connected beagle that way
  • [02:47:58] <banderson> dcordes: I think until you get serial proven to work you will never be able to diagnose what is going on with beagle.

  • [02:53:24] <banderson> dcordes: yes
  • [02:53:59] <banderson> dcordes: just make sure you know what pins are 2,3
  • [02:55:44] <banderson> dcordes: here is picture of serial port on pc. Pins 2,3 are on the top row and are the 2 and 3 pin from left

  • [02:56:41] <banderson> dcordes: then just look at how your loopback connector is plugging into the port and make sure it will match up
  • [02:58:03] <dcordes_> banderson: ok then I did it also in linux correctly
  • [02:58:27] <banderson> dcordes: did you say you had usb-serial adapter?
  • [02:58:28] <dcordes_> http://www.pccables.com/07120.htm this is what I looked at before. it's about exactly the same adapter as I have
  • [02:58:44] <dcordes_> no, not yet. will get one in a few hours if I don't get this working here
  • [02:59:34] <banderson> dcordes: just to be clear you just used that cable to see which pins are what not to actually make a loopback?
  • [02:59:59] <dcordes_> so from the pov of the ladyada picture, I put a 2 pin jumper on the 2nd and 3rd pin from the left in top (5pin) row
  • [03:00:26] <dcordes_> no problem since I only put a jumper
  • [03:00:29] <dcordes_> no soldering
  • [03:01:44] <dcordes_> ok, fired up the windows terminal program with options com1 (that's the only one widnows does offer), baud rate: 115200, data 8bit, parity none, stopbits 1bitm, flow control none
  • [03:02:28] <banderson> dcordes: All sounds good
  • [03:03:04] <banderson> dcordes: so what type of computer is this? laptop? pc? how old?
  • [03:03:23] <dcordes_> asus p5kc from 2007
  • [03:03:37] <dcordes_> I looked up the serial port in the user manual
  • [03:04:00] <dcordes_> the pinout is exactly as beagleboard (just with pin 10 removed, which is not used anyway to my understanding)
  • [03:04:08] <banderson> dcordes: is the serial port physcally apart of the mb or is it in one of the slots
  • [03:04:46] <banderson> dcores_: you had to hook a cable to the motherboard to get serial out?
  • [03:04:50] <dcordes_> it is 9 onboard pins
  • [03:05:02] <banderson> dcordes: interesting
  • [03:05:12] <dcordes_> yea right and on that cable (male d-sub 9) I have the jumper on pin 2/3
  • [03:05:40] <banderson> dcordes: now I am understanding what you are saying...
  • [03:06:13] <banderson> dcordes: do you have link to your mb manual?
  • [03:06:22] <dcordes_> right
  • [03:07:22] <dcordes_> using this cable http://images.conrad.de/xl/7000_7999/7400/7420/7429/742910_BB_00_FB.EPS.jpg

  • [03:09:46] <dcordes_> it matches the pinout of the asus onboard com1 as documented in their user manual
  • [03:09:48] <banderson> dcordes: how do you know for sure what way the cable is wired?
  • [03:10:20] <dcordes_> because the pin numbers match 1:1
  • [03:10:45] <banderson> dcordes: I have several of those type of cables laying around but they can be different.
  • [03:11:04] <dcordes_> I open the cable
  • [03:11:20] <banderson> dcordes: ahhh that is good!
  • [03:11:50] <dcordes_> funny the d-sub wiring is bs
  • [03:11:58] <banderson> dcordes: does mb have a pin 1 marking
  • [03:12:18] <dcordes_> yea
  • [03:13:20] <banderson> dcordes: just to eliminate one more variable try connecting pin 2-3 on mb pins...you will have to go diaginal across rows...
  • [03:13:33] <dcordes_> the d-sub in the adapters I bougt is soldered like this when you go on the ribbon from one to the other side: 1upper row, 1 lower row, 1 upper row
  • [03:13:35] <dcordes_> etc
  • [03:13:50] <dcordes_> I'm quite sure now the cable is wrong
  • [03:14:15] <banderson> dcordes: ya that is backwards...that to connect to a different style mb connector

  • [03:33:11] <jkridner> http://eLinux.org/BeagleBoard is a bit of a faq.
  • [03:33:28] <jkridner> we've started to work up one at http://BeagleBoard.org/support/faq, but it is just getting started.
  • [03:34:02] <lgentili> maybe you think, I'm a bit crazy, but I've been following the irclogs since this started
  • [03:34:10] * jkridner just found there is another faq at http://beagleboard.org/faq/ that I need to delete.
  • [03:34:36] <jkridner> welcome to the live room! :)
  • [03:34:46] <lgentili> :)
  • [03:34:48] <lgentili> I think, the irclogs has more value than people think
  • [03:35:09] <lgentili> you could make a good faq from the irclogs
  • [03:35:12] <_Ade_> is there an easy way to search the irclogs?
  • [03:36:30] <dcordes_> banderson: ok bye and thanks. I will try making a direct idc10-idc10 now
  • [03:36:45] <banderson> _Ade_: I just do google search with site:http://www.beagleboard.org/irclogs
  • [03:38:15] <lgentili> I think you can make a book from the irclogs
  • [03:38:33] <lgentili> You learn alot plus I get a lot of fun reading this
  • [03:40:41] <lgentili> jkridner: did you think about this?
  • [03:41:46] <jkridner> I deleted the old faq.
  • [03:42:00] <jkridner> the new faq is incomplete, but is at http://beagleboard.org/support/faq
  • [03:42:18] <jkridner> I'd absolutely love it if someone made a book from the faq.
  • [03:42:39] <jkridner> a nice place to start working on the book would be at http://beagleboard.org/project/documentation/
  • [03:42:56] <lgentili> NO!~
  • [03:43:01] <jkridner> err, book from the irclog.
  • [03:43:16] <jkridner> sorry, had faq on the fingers.
  • [03:43:18] <lgentili> now, I noticed you deleted the old irclogs
  • [03:43:22] <lgentili> doh!
  • [03:43:25] <jkridner> I did?
  • [03:43:34] <jkridner> irclogs should go back a long way.
  • [03:43:58] <lgentili> the oldest is 2007-10-24
  • [03:44:00] <jkridner> all the way back to october 24th, when I was all alone.
  • [03:44:21] <jkridner> were there any logs before that?
  • [03:44:21] <lgentili> sorry, my bad
  • [03:44:30] <jkridner> first thing I logged was when I started the logbot. :)
  • [03:45:07] <jkridner> looks like I got my first Beagle to boot on 12-14.
  • [03:45:25] <lgentili> Maybe I'm crazy, but I don't like watch tv
  • [03:45:31] <jkridner> I'm pretty sure Khasim and/or Steve had one booting before me.
  • [03:45:43] <lgentili> so when I wanna read something cool, I read the irclogs
  • [03:45:59] <lgentili> everydayyyyyyyyyyyyyyy :P
  • [03:46:22] <lgentili> sadly my english suck, if not I could do a doc with all this

  • [03:47:07] <dcordes_> I was about to suggest you to try reinstalling the gcc-symlinks packages when you went offline
  • [03:47:12] <jkridner> I used to have a better setup for linking between the irclog pages.
  • [03:47:24] <jkridner> I accidentally wiped that out.
  • [03:47:25] <lgentili> jkridner: tell my story in your presentations
  • [03:48:01] <jkridner> dcordes_: how do I do that? I thought I did it, but it didn't seem to take.
  • [03:48:18] <jkridner> also, libexec doesn't seem to have cc1 in it (though I don't know if it should)
  • [03:48:35] <jkridner> lgentili: what is your story? that you don't like to watch tv, but instead read irclogs?
  • [03:48:45] <lgentili> well
  • [03:49:05] <lgentili> I'm telling you that, I'm a techy guy
  • [03:49:23] <lgentili> And I think your project is so cool, that I get a lot fun

  • [03:58:48] <dcordes_> if beagle gives sound and video output, should it also output data to the rs232?
  • [03:59:40] <dcordes_> i.e. should I get data duringe every powerup while the terminal program is active
  • [04:00:15] <lgentili> I don't know in the beagle
  • [04:01:04] <lgentili> but in linux you configure the kernel console with a tty to output true the rs232
  • [04:03:13] <lgentili> you talk about the command line output?
  • [04:03:24] <dcordes_> yes
  • [04:04:20] <lgentili> I'm pretty sure that the kernel was build with that
  • [04:04:26] <lgentili> built
  • [04:04:35] <dcordes_> there's no linux kernel on it
  • [04:04:38] <dcordes_> only a bootloader
  • [04:05:52] <dcordes_> it seems like my compuer's serial is broken
  • [04:06:47] <lgentili> usually the setup default for serial consoles is 115200 n81
  • [04:06:57] <lgentili> which terminal are you using?
  • [04:07:02] <lgentili> host terminal
  • [04:07:04] <dcordes_> I tried plenty.

  • [04:07:33] <dcordes_> gtkterm
  • [04:08:03] <dcordes_> and even when I short the rx tx pins, I get nothing on the console
  • [04:08:23] <lgentili> hmm that's bad sign
  • [04:08:42] <lgentili> a loopback should work
  • [04:09:46] <lgentili> do you any other rs232 or usb to serial ?

  • [04:43:55] <lgentili> would be great if the OMAP3 was in 1mm ball pitch
  • [04:44:06] <lgentili> :P
  • [04:45:43] <lgentili> I don't care the big package
  • [04:49:04] <jkridner> 0.65mm will use 0.8mm design rules (as I'm sure you've heard), so it'll be reasonably easy to work with.
  • [04:49:16] <jkridner> then, biggest challenge is the DDR layout.
  • [04:49:52] <lgentili> yep, the pop package helped alot with the ddr layout
  • [04:50:11] <lgentili> but, the things are getting harder for hobbiest :(
  • [04:50:21] <lgentili> too fast for my taste
  • [04:50:44] <lgentili> I started to solder smd 5 years ago
  • [04:51:03] <ds2> a OMAP3 + POP + board to break out the remaining pins to the end of the board will be quite useful
  • [04:51:19] <lgentili> true
  • [04:51:48] <ds2> a TWL4030 on that same minimal board would be the greatest thing in the world
  • [04:52:54] <lgentili> When I get 1 board, first thing I will do is to desonder the dvi chip
  • [04:53:03] <lgentili> and hand solder an lcd
  • [04:54:22] <ds2> how do you plan to connect the LCD? most of them have rather unfriendly connectors on them (assorted flex circuit connectors)

  • [04:54:40] <jkridner> how does what you are talking about compare to the LPD SOM?
  • [04:54:56] <ds2> what I had in mind is about 1"x1" or smaller
  • [04:55:08] <ds2> the LPD SOM is giantic
  • [04:55:32] <ds2> plus it has stuff that not everycares about like the BRF bluetooth chip
  • [04:55:43] <lgentili> this is my board http://www.youtube.com/watch?v=qIBE5FNIgWY
  • [04:55:46] <ds2> support issues aside ;)
  • [04:56:08] <lgentili> lcd are not hard to add
  • [04:56:48] * dirk2 (n=dirk@F3001.f.strato-dslnet.de) has joined #beagle
  • [04:56:52] <ds2> conceptually a LCD is very hard to add but I have rarely seen more then one LCD with the same connectors except for alphanumeric ones
  • [04:57:02] <ds2> s/very hard/not very hard/
  • [04:57:04] <ds2> blah
  • [04:57:49] <lgentili> you need to make an adapter with patience
  • [04:58:45] <lgentili> do you see de board near the lcd
  • [04:58:59] <ds2> yep and that makes it difficult to make a generic board that many people can use to interface to an LCD
  • [04:59:01] <lgentili> that the "ticon" (timer controller)
  • [04:59:13] <ds2> if you know enough to make the adapter, chances are you know a lot more on how to go about it
  • [04:59:46] <ds2> having a little carry board to put connections on the edge eliminations the need to do a complex BGA assembly which can kill low volume thing :/
  • [05:00:24] <lgentili> I like your idea
  • [05:00:26] <ds2> in theory one can do it with a toaster oven but that is a one shot process and one needs to validate all the ball's bounding

  • [05:01:29] <lgentili> I want an X-ray machine ! :(
  • [05:01:46] <ds2> an X-ray machine won't help that much
  • [05:02:11] <lgentili> well you can see how is the bga chip mounted
  • [05:02:14] <ds2> it can probally be inspected with a machinist's optical comparator or maybe even doing a BDM scan via jtag
  • [05:02:51] <lgentili> BDM is good for that
  • [05:03:39] <lgentili> I've changed my last project from the imx31 to mpc5121e because the ball pitch
  • [05:03:54] * Beagle4 (n=Beagle4@124-169-113-72.dyn.iinet.net.au) has joined #beagle
  • [05:04:14] <ds2> what's the difference in pitch between the imx31 and the mpc5121e?
  • [05:04:34] <lgentili> imx31 is .5 and now there is a .65
  • [05:04:39] <ds2> all I know about the MPC is that it is PPC core possibly with a risc co processor
  • [05:04:48] <lgentili> but mpc5121e is 1mm!
  • [05:05:01] <lgentili> so is easy-cheap to manufature
  • [05:05:16] <ds2> I see. how many layers did you have to use with the mpc and did you need blind vias?
  • [05:05:17] <lgentili> 800 mips + powervr + audio coprocessor
  • [05:05:49] <lgentili> I'm not the harwared guy, but first round they used 6 layers
  • [05:05:58] * Beagle4 is now known as kimbecause
  • [05:05:59] <lgentili> but they tell me is possible to doit with 4
  • [05:06:22] <ds2> hmmm 0.040 center to center space is pretty tight to route more then one trace
  • [05:06:55] <lgentili> they found a mpc5200 with 4 layers, and the bga package is the same
  • [05:07:30] <kimbecause> Hey all was wondering if I could ask some simple questions ???
  • [05:07:51] <kimbecause> A) is there a forum I can lurk on
  • [05:07:53] <lgentili> no problem with me
  • [05:07:54] <ds2> ask away, don't mean to scare people off with fab details ;)
  • [05:08:31] <kimbecause> b) what sort of linux does beagle run? Is there a mips ubuntu / gentoo it would run
  • [05:09:17] <ds2> (b) - ARM flavor, with several choices to choose from... default repo is te linux-omap tree
  • [05:09:20] <lgentili> mips ubuntu? the chip is an ARM
  • [05:09:48] <kimbecause> c) I was thinking of making a low power torrent box / squid proxy / firewall (maybe) using a usb hard drive. would this work?
  • [05:09:59] <kimbecause> ok sorry ds2
  • [05:10:40] <lgentili> this is like a pc from the year 2000
  • [05:10:43] <ds2> make it solar powered for additional fun ;)
  • [05:11:10] <lgentili> with the same processing power
  • [05:11:35] <lgentili> all that work in linux almost work in the beagle
  • [05:12:40] <lgentili> ds2: other problem that has the imx31 is the companion chip
  • [05:12:41] <kimbecause> mmk ... like I said would only be running a few things; for the same price I would go with a wrt router except for no usb for hard drive
  • [05:13:09] <lgentili> you have more power than a wtr router
  • [05:13:39] <kimbecause> yer ... also here in aus they are similar(ish) price
  • [05:15:28] <ds2> lgentili: what's the problem with the atlas?
  • [05:15:32] <lgentili> usually a router has a ARM9 or a mips processor
  • [05:15:35] <kimbecause> d) so is there a web site for a generic linux I can look at? ive done a bit of googalizing but cant really find anything
  • [05:15:50] <lgentili> the Atlas is .4 mm ball pitch
  • [05:16:04] <ds2> kimbecause: you looking for a full distribution or just Linux (the kernel)?
  • [05:16:13] <ds2> ouch .4 mm
  • [05:16:42] <ds2> 0.016 is TIGHT
  • [05:16:46] <kimbecause> full distro to get basic shell / ssh / squid / command line torrent
  • [05:16:52] <lgentili> if you use the imx31 with .65 the only way to go is with wolfson sound chip for example
  • [05:17:23] <ds2> kimbecause: look at the OpenEmbedded/Angstrom stuff for non commercial... there are probally other efforts but that's one I hear a lot about
  • [05:17:50] <kimbecause> ok thonks
  • [05:17:53] <kimbecause> thanks
  • [05:18:21] <ds2> thought the iMX31 did AC97 also? isn't there a NXP leaded AC97 codec?
  • [05:19:04] <lgentili> I'm not sure
  • [05:19:27] <ds2> come to think of it, there got to a leaded I2S codec
  • [05:19:32] <ds2> to be
  • [05:21:12] <lgentili> I was looking for drivers already ported for the chip
  • [05:21:19] <kimbecause> one last
  • [05:21:24] <kimbecause> one *
  • [05:21:34] <ds2> codecs are pretty trivial to port ;)
  • [05:21:44] * ds2 ducks in case steve is around
  • [05:22:50] <lgentili> I'm just a rookie with linux :(
  • [05:23:19] <lgentili> I've been doing driver more than 10 years but this is my first with linux
  • [05:24:11] <kimbecause> e) there is an american adapter for beagle; but could a find an australian one / adapter. Would it run from say an ipod usb charge adapter?
  • [05:24:37] <kimbecause> or did I see it run from a powered sub hub?
  • [05:25:01] <kimbecause> usb*
  • [05:25:45] <lgentili> do you have 220 volts in AU?
  • [05:26:35] <ds2> adapter? I donno if there is a commercially made one but you can power it off a USB port
  • [05:27:09] <ds2> and I don't mean feeding power via the mini-AB jack; you can either make or buy a barrel connector to a USB A connector
  • [05:27:45] <ds2> but if you don't need USB host functionality, a mini B to USB A cable will power it just fine with the mini AB jack
  • [05:28:59] <lgentili> ds2: did you noticed that in a couple of years the hardware will be free?!
  • [05:30:08] <lgentili> this is the beginnig, $150 for a piece of hardware that can run normal applications like a pc
  • [05:33:04] <kimbecause> ds2: so there is a single port that either powers the board or hosts usb? what i meant by adapter was http://dkc1.digikey.com/us/mkt/beagleboard.html on the right hand side
  • [05:33:49] <kimbecause> but I see there is also a normal power socket
  • [05:37:37] <kimbecause> what I meant by powered by powered usb hub was this: http://flickr.com/photos/25485153@N00/2535894759/
  • [05:37:54] <kimbecause> anyway thanks for everything ... catya

  • [05:40:24] <ds2> heh... donno about free
  • [05:41:43] <lgentili> well a good exercise to "see" the future before other is.... thinks what could happend if something were "free" (or soo cheap)
  • [05:42:22] <lgentili> I'm trying to imagine what will happend in the next 2 years with the computing getting soooo cheap

  • [05:44:05] <ds2> the ability to have the same amount of computing power today but the power source will be a solar cell with a lemon for the cloudy days
  • [05:45:09] <lgentili> well power managment or economy is future for sure.
  • [05:45:20] <lgentili> I mean really important

  • [08:30:07] <Beagle0> so do I
  • [08:30:26] <uberfry> I'd rather have parallel adapter
  • [08:30:27] <Beagle0> I think dvi (or vga) is pretty good for a board like this
  • [08:30:34] <Beagle0> hehehe
  • [08:30:37] <uberfry> yes
  • [08:30:38] <uberfry> but still
  • [08:30:44] <Beagle0> 8X8 centimeters ;)

  • [08:34:28] <uberfry> valhalla: no, but if there's no parallel interface by november, I'll make my own dvi to parallel converter
  • [08:34:39] <uberfry> or maybe even memory driven lcd driver

  • [12:50:52] <jkridner> good morning.
  • [12:51:03] <mru> morning jkridner
  • [12:51:07] <jkridner> my mac pro died today. :(
  • [12:51:14] <jkridner> no idea why--just won't turn on.
  • [12:51:23] <mru> time to get a real computer, perhaps
  • [12:52:04] <jkridner> well, the idea was to get some hardware I didn't have to fuss with--but I can see that worked out.
  • [12:52:40] <mru> as much as I dislike x86, modern PCs aren't much fuss
  • [12:52:45] <jkridner> mru, what would you qualify as a real computer?
  • [12:52:49] <mru> assuming you run a real OS of course
  • [12:52:56] <jkridner> Linux?
  • [12:53:00] <mru> that'll do
  • [12:53:06] <jkridner> FreeBSD?
  • [12:53:14] <mru> if you prefer
  • [12:53:21] <jkridner> OpenSolaris? ;)
  • [12:53:28] <mru> why not?
  • [12:53:55] <jkridner> general lack of community, but otherwise OK.
  • [12:54:20] <mru> now what's a real computer? they're getting rare, that's for sure
  • [12:54:40] <mru> workstations tend to be all x86
  • [12:54:43] <jkridner> with Mac OS being built on a mach kernel and running all my *nix apps, Mac OS seems real enough to me.
  • [12:54:49] <mru> there are still some real servers to be found
  • [12:55:19] <jkridner> Mac Pro was x86.
  • [12:55:39] <mru> macos causes no end of trouble for ffmpeg
  • [12:55:45] <mru> there's always some subtle difference
  • [12:56:03] <mru> like their compiler using a different syntax for altivec intrinsics
  • [12:56:16] <mru> or their compiler not compiling code that works fine with stock gcc
  • [12:56:18] <jkridner> beagle kept running overnight:
  • [12:56:19] <jkridner> jdk-mini-2:~ jason$ ssh root@192.168.0.105

  • [12:56:48] <jkridner> screen -r and I'm where I left off on it.
  • [12:56:58] * jkridner loves screen
  • [12:57:42] <jkridner> doesn't MacOS use gcc? They make patches?
  • [12:57:55] <mru> they patch it beyond recognition
  • [12:58:15] <mru> and each release breaks things in new ways
  • [12:58:32] <mru> they're executable format sucks too
  • [12:58:49] <mru> their...
  • [12:58:54] * mru hangs his head in shame
  • [12:59:13] <jkridner> I'll forgive you. ;)
  • [12:59:59] <jkridner> good thing I kept my mini around.
  • [13:00:12] <mru> mac or car? ;-)
  • [13:00:16] <jkridner> btw, the reason I switched to macs was because of the noise of all other PCs I bought.
  • [13:00:32] <mru> my pc is very quiet
  • [13:00:49] <mru> water cooling, large, slow fans
  • [13:00:52] <jkridner> can't say I'm fond of the cooper, given the mileage for such a small car.
  • [13:01:24] <jkridner> maybe if I knew where to find a decent maker with quiet fans that didn't fail.
  • [13:01:42] <mru> I build my own systems
  • [13:01:46] <jkridner> this failure today certainly lowered my opinion of Apple signifiantly.
  • [13:01:54] <jkridner> significantly
  • [13:02:16] <mru> mine can't get much lower
  • [13:02:46] <mru> although to be fair, osx was a huge improvement
  • [13:02:47] <jkridner> I'll check back with you in 15 years and see if you are still building your own systems.
  • [13:02:55] <jkridner> it is fun and all, but a honking waste of time.
  • [13:03:04] <mru> not really
  • [13:03:17] <jkridner> never, ever would have used a Mac before osx.
  • [13:03:25] <mru> I built my current machine a year and a half ago
  • [13:03:35] <mru> took me no more than an evening
  • [13:03:52] <jkridner> including research into components?
  • [13:04:31] <mru> not much needed
  • [13:04:56] <mru> I knew I wanted core2 cpu, nvidia fanless graphics card, seagate hard drives
  • [13:05:36] <jkridner> what about the case and cooling system?
  • [13:05:46] <mru> I had the case already
  • [13:05:57] <mru> 19" rack-mount
  • [13:06:06] <jkridner> well... add the time in it took to find that.
  • [13:06:16] <jkridner> and where do you keep a rack system?
  • [13:06:36] <mru> I didn't find it... it just came into my possession
  • [13:06:40] <mru> it's not in a rack
  • [13:07:15] <jkridner> well, the fact that you already had a nice case that you trust was a huge time saver.
  • [13:07:24] <mru> it came with the bits to convert to a tower
  • [13:08:04] <jkridner> also, since I didn't want to mess with my hardware for a few years, I got a bit more CPU and graphics power.
  • [13:08:16] <jkridner> so much for not messing with it.
  • [13:08:38] <jkridner> got up this morning and it was off and the power button does nothing.
  • [13:08:54] * cian (n=cianh@93.107.139.22) has joined #beagle
  • [13:08:56] <mru> possibly a power supply failure
  • [13:09:03] <mru> do they use atx psu?
  • [13:09:06] * jkridner is not liking the case and the ability to probe into it today!
  • [13:09:25] <jkridner> I don't know. It is behind some aluminum casing.
  • [13:09:47] <jkridner> spent about 30 seconds looking for a way to remove the casing to evaluate it.
  • [13:10:27] <jkridner> ultimate shame: I'm now waiting for the *mall* to open so that I can take it in.
  • [13:11:01] <jkridner> you might just convince me to switch back to PC hardware.
  • [13:11:27] <jkridner> my Gentoo box was just so freakin' loud.
  • [13:11:46] <mru> self-built systems may take a little more time initially
  • [13:11:48] <jkridner> so, I was rather happy to switch to gentoo-alt on my mac mini.
  • [13:12:13] <mru> but if something goes wrong, you know exactly where things are
  • [13:13:08] * jkridner|work (n=a0321898@nat/ti/x-9ce1603e543e615d) has joined #beagle
  • [13:14:39] <jkridner> agreed. I still believe the equation has flipped for me as I'm getting older and I get more things on my to-do list.
  • [13:15:27] <jkridner> I wouldn't suggest a mac for everyone.
  • [13:15:38] <mru> let's just say I spend far less time tinkering with the hardware than I used to
  • [13:15:40] <jkridner> we'll see after today if I'd still recommend one to *anyone*.
  • [13:16:16] <mru> I don't believe there is anything that's suitable for everyone
  • [13:16:17] <jkridner> I think what really got me sick of it was building systems for other people.
  • [13:16:21] <mru> except oxygen and water
  • [13:16:35] <mru> oh, I never do that
  • [13:16:53] <jkridner> I used to do that quite a bit. I have a lot of family in the area.
  • [13:17:13] <jkridner> my mom used to run a business and I'd be IT support for her clients.
  • [13:17:35] <jkridner> I started charging them, then raising my prices so they wouldn't come back...
  • [13:17:41] <mru> ;-)
  • [13:17:49] <jkridner> to my surprise, they kept coming back anyway.
  • [13:18:17] <jkridner> till I said no or tried to send someone else a couple of times, then they found it was a waste of their time.
  • [13:18:31] <jkridner> people will pay good money to avoid wasting their time.
  • [13:18:46] <jkridner> and I'm really sick of computers that waste my time.
  • [13:19:17] <jkridner> I'll be quite happy when enough is running on Beagle that it becomes an everyday computer for me.
  • [13:19:41] <jkridner> it is huge for me that you have a full-backup on-a-disk that is easy to move around.
  • [13:20:01] * jkridner misses the days of the boot-floppy and no hard-disk-drives.
  • [13:20:42] <jkridner> guess there aren't enough people active right now to beat me up for that statement.
  • [13:21:59] <mru> I just about remember those times
  • [13:22:22] <jkridner> HDDs were the worst invention relative to computer ease-of-use.
  • [13:22:24] <mru> can't say I miss the floppy
  • [13:22:32] <mru> how's that?
  • [13:22:40] <jkridner> when I was growing up, my mom let me use the computer all the time...
  • [13:23:02] <mru> mine didn't, but I'd use it anyway...
  • [13:23:07] <jkridner> she told me: unless you physically beat it, there is nothing you can do to hurt it... so try whatever you'd like.
  • [13:23:18] <jkridner> with a hard-drive...
  • [13:23:38] <jkridner> all of the info your computer needs to run is all in one fragile place.
  • [13:23:40] <mru> I once deleted a few too many files off the hard drive
  • [13:23:48] <jkridner> so, if someone plays with it, they can mess it all up.
  • [13:24:12] <jkridner> in the days of tapes and floppies, my mom would just lock-away the ones she needed for work.
  • [13:24:17] <mru> that's why you have unprivileged users and backups
  • [13:24:31] <jkridner> and we all understood the value of backups.
  • [13:24:41] <jkridner> that's nonsense!
  • [13:24:54] <mru> if I'm letting anyone onto my computer for more than a few minutes, I set up a user for them
  • [13:24:54] <jkridner> how are you supposed to learn in some crippled account?
  • [13:25:12] <mru> virtualisation?
  • [13:25:25] * jkridner shakes his head.
  • [13:25:49] <jkridner> I was allowed to try ANYTHING I could do with the computer that didn't mean taking the case off.
  • [13:26:31] <jkridner> vitualization is nice, but it isn't a substitute for hacking into the running executive.
  • [13:26:37] <mru> hehe
  • [13:26:58] <jkridner> and it still doesn't prevent you from hacking into things.
  • [13:27:23] <mru> I guess I get my hacking needs fulfilled on embedded systems
  • [13:27:37] <jkridner> no, there's no substitute to having 100% your own working environment you can do whatever you want with.
  • [13:27:42] <mru> so I'm content viewing the pc as a tool to be used as intended
  • [13:27:52] * cian (n=cianh@93.107.139.22) Quit (Read error: 110 (Connection timed out))
  • [13:28:11] <mru> but you're right, I do feel crippled if I don't have root access
  • [13:28:19] <jkridner> I used to love PCs and the current state makes me very frustrated.
  • [13:28:28] <mru> the one exception to that was at university
  • [13:28:34] <mru> the system there actually worked really well
  • [13:28:40] <jkridner> with my Beagle, I can carry the entire environment around on an SD card and switch Beagles.
  • [13:28:44] <mru> and if you needed something, the admins would usually make it happen
  • [13:29:00] * cian (n=cianh@93.107.7.167) has joined #beagle
  • [13:29:05] <jkridner> I can make a 100% backup and get back to where I was instantly.
  • [13:29:35] <mru> backing up all of my 500GB drive isn't really feasible
  • [13:29:46] <jkridner> now, I'd prefer if my Beagle was the same speed as my Mac Pro and had the same throughput to storage, mind you.
  • [13:29:51] * valhalla (n=valhalla@81-174-21-16.dynamic.ngi.it) Quit ("Leaving")
  • [13:30:03] <jkridner> I guess you are just a disaster waiting to happen then?
  • [13:30:14] <jkridner> no USB drive for backup?
  • [13:30:18] <mru> the drives are mirrored
  • [13:30:23] <jkridner> k.
  • [13:30:32] <jkridner> I was wondering about your for a minute. :)
  • [13:30:37] <jkridner> your=you
  • [13:30:43] <mru> and most of it is music and movies
  • [13:30:49] <sakoman> jkridner: you might just have to reset the power management chip
  • [13:31:02] <jkridner> is there a way to do that?
  • [13:31:06] <mru> my home directory is only a few GB
  • [13:31:08] <sakoman> have you googled 'mac won't start'?
  • [13:31:22] <jkridner> no, I was wasting my time ranting instead. :)
  • [13:31:38] <sakoman> It differs by model IIRC
  • [13:31:48] * jkridner *thinks* about spending time more efficiently, but doesn't actually do it.
  • [13:31:54] <sakoman> Happened to me once or twice over the years :-)
  • [13:32:36] * sakoman hopes mru doesn't hate him because he used to work at Apple
  • [13:32:47] <mru> we all make mistakes
  • [13:33:14] <mru> you apparently saw the error of your ways
  • [13:34:25] <mru> there... 4% faster h264 decoding
  • [13:34:42] <mru> and it's still spending 45% time in unoptimised functions
  • [13:35:10] <sakoman> so we can expect at lest another 5%? ;-)
  • [13:35:57] <mru> I should hope so
  • [13:37:44] <jkridner> DSP Link is finally available for OMAP3530 with GPL kernel source: https://www-a.ti.com/downloads/sds_support/targetcontent/link/link_1_50/index.html
  • [13:38:02] <jkridner> that should open up a few avenues of optimization as well.
  • [13:38:21] <jkridner> I think the big challenge is how to share the DSP between apps.
  • [13:38:42] <jkridner> it is what Codec Engine is designed for, but I imagine mru wouldn't want to use it.
  • [13:39:15] <jkridner> the MSGQ/MessageQ API is the lightweight interface using Link.
  • [13:39:41] <jkridner> easy enough to reverse engineer as well.
  • [13:40:23] <jkridner> sakoman: so far, all google links are useless.
  • [13:41:02] <sakoman> did you try the apple.com support section?
  • [13:41:08] * jkridner is sick of seeing macbook pro, when looking for macpro
  • [13:41:20] <mru> jkridner: isn't everything in the TRM? or is reverse engineering still required?
  • [13:42:07] <jkridner> everything is in the TRM, but I'm trying to save you time and tempt you into making new optimizations on the DSP.
  • [13:42:17] * jkridner should know better than to think it is about saving time.
  • [13:43:43] <sakoman> http://support.apple.com/kb/HT1806?viewlocale=en_US
  • [13:44:20] <sakoman> use the "push the switch" method at the end
  • [13:44:58] <DJWillis> jkridner: Do you know if the the old source tars for x-loader and u-boot still up on the Beagleboard site anywhere? Trying to 'diff' out an issue. Looking for one of the TI U-Boot 1.1 vairents.

  • [15:40:23] <mru> speaking of that, we need make a decision what to do with the various display drivers
  • [15:40:53] <mru> the first question is, what interfaces does userspace need?
  • [15:44:26] * khasi1 (n=a0393720@192.163.20.231) Quit (Remote closed the connection)
  • [15:44:54] <khasim> mru: sysfs is definitely not the optimal one. but it is easy to use.
  • [15:45:22] <mru> I'd rather have something more standard
  • [15:45:37] <mru> when possible
  • [15:45:58] <khasim> I tried getting some views on this from FBDEV but nothing worked out.
  • [15:46:17] <khasim> We export V4L and FBDEV interfaces for DSS
  • [15:46:36] <mru> we definitely want the plain /dev/fb0 device
  • [15:47:00] <mru> applications will want to use Xv
  • [15:47:11] <mru> maybe some can use v4l2
  • [15:47:22] <mru> v4l2 can be more efficient than Xv
  • [15:47:29] <mru> but it's harder to use
  • [15:47:39] <khasim> yes fbdev is definitely a requirement and V4L is being used in other frameworks like OpenMax and
  • [15:47:40] <mru> one option might be to implement Xv on top of v4l
  • [15:47:51] <mru> does anybody use openmax?
  • [15:47:54] <khasim> yes Xv on V4L would be really good
  • [15:48:18] <mru> I need to read up on v4l
  • [15:48:30] <mru> it's been a few years since I messed around with that stuff
  • [15:48:38] <mru> and then I only used it for input
  • [15:48:46] <khasim> Actually V4L exports lot of standard APIs that apply effectively for a high end display subsystem
  • [15:49:20] <khasim> yeah, V4L even today is considered mainly for input, but the output is much better as well
  • [15:49:40] <khasim> I had proposed this last year and as usual dropped due to other activities
  • [15:50:29] <khasim> http://linux.omap.com/pipermail/linux-omap-open-source/2007-March/009187.html
  • [15:50:54] <khasim> http://lwn.net/Articles/225644/
  • [15:51:03] <mru> megapatches like that often get ignored
  • [15:51:09] <mru> nobody has the time to analyse them
  • [15:51:58] <khasim> Actually Mauro was very interested in this, but I didnt follow it up as there were more basic things that were missing, I thought I would first fix the basic ones then ... missed it completely
  • [15:52:12] <mru> this is a typical case of opensource and commercial clashing
  • [15:52:16] <khasim> We have an internal team that is working on it now.
  • [15:53:00] <khasim> I have also created a list where we have open community and TI teams interested in DSS functionality, even that is going slow :(
  • [15:53:06] <mru> the problem with many companies is that they take a snapshot of the linux kernel, say, go off internally and hack on it for a year, then send a megapatch
  • [15:53:15] <mru> meanwhile, everything has changed around it
  • [15:53:22] <mru> and integrating the patch is hell
  • [15:53:28] <khasim> but I think there will soon be a new design to address the open issues of FBDEV and V4L2
  • [15:53:42] <mru> the development needs to be in the open all along
  • [15:53:51] <khasim> but my patch was on the live kernel
  • [15:53:58] <khasim> I had ported it then
  • [15:54:14] <mru> I was speaking generically
  • [15:54:23] <mru> TI seem to be better than average in this regard
  • [15:54:35] <khasim> ok, but that is what TI will be will doing in near future
  • [15:54:54] <khasim> at least we have started it for omap3530 and 3430, we will soon be doing the same for davinci as well
  • [15:56:33] <mru> if you want broad acceptance in the opensource world, you need to provide interfaces that existing apps can use
  • [15:56:44] <mru> preferably without change
  • [15:57:04] <mru> even if some new interface would fit better with the chip design
  • [15:58:03] * khasi1 (n=a0393720@192.163.20.231) has joined #beagle
  • [15:58:43] <khasi1> mru: sorry lost my internet connection :(
  • [15:58:46] <khasi1> back again.
  • [15:59:04] <mru> I didn't say much
  • [15:59:35] <khasi1> I agree that drivers need to use standard interfaces but most of the hardware functionality supported by high end application process cannot be addressed
  • [15:59:59] <khasi1> like say I cannot address mirroring or multiple device dynamic switching, etc in FBDEV today
  • [16:00:15] <jkridner> cannot say I'd ever buy another Mac Pro.
  • [16:00:37] <jkridner> power supply is burnt out and I need to wait 3-5 business days.
  • [16:00:39] <mru> what do you mean by multiple device dynamic switching?
  • [16:01:01] <khasi1> like S-video DVI LCDs switching capability
  • [16:01:14] <khasi1> there is no standard way to do that in Linux,
  • [16:01:24] <khasi1> Linux thinks there is only one device always
  • [16:01:28] <jkridner> computer was purchased in May.
  • [16:02:05] <mru> fbdev could be easily extended to support mirroring and rotation
  • [16:02:56] <khasi1> yeah we have to do that, but adding more functionality like Cropping, YUYV , UYVY, etc will still take lot of time...
  • [16:03:20] <khasi1> actually V4L2 addresses all these in a standard way
  • [16:03:35] <mru> yes, but it is very complex to use
  • [16:03:42] <khasi1> but our apps are not based on V4L2
  • [16:04:20] * khasim (n=a0393720@192.163.20.231) Quit (Remote closed the connection)
  • [16:04:30] <khasi1> yeah but it all depends on how we would like to use hardware dynamically
  • [16:04:59] <khasi1> like should I support dynamic configuration of scaling and color conversion parameters?
  • [16:05:17] <khasi1> should I support Alpha blending?
  • [16:05:40] <mru> I'd say it's better to have 90% of existing apps work out of the box, than having support for exotic things that no apps actually use
  • [16:06:14] <khasi1> :) we need to create such apps - that leverage the functionality exported by hardware.
  • [16:06:20] <mru> sure
  • [16:06:32] <mru> but supporting existing apps is still important
  • [16:07:00] <mru> besides most tasks don't need all those fancy features
  • [16:07:02] <khasi1> in my opinion existing apps should evolve...
  • [16:07:14] <mru> of course they should
  • [16:07:16] <mru> and they will
  • [16:07:24] <khasi1> this is what every one thought before iphone...
  • [16:08:17] <mru> I think the right path is to first support what existing apps need
  • [16:08:27] <mru> then start adding more stuff
  • [16:08:36] <khasi1> yes, that is true.
  • [16:08:48] <mru> right now nothing works
  • [16:09:06] <khasi1> on latest GIT ' :)
  • [16:09:21] <khasi1> which we have started migrating...
  • [16:09:41] <khasi1> I think in few months from now we should have a good DSS driver set for OMAP
  • [16:09:58] <khasi1> supporting FBDEV and V4L2 applications.
  • [16:10:25] <khasi1> I look forward to community to review the desing and make the corrections then and there

  • [18:17:15] <Beagle1> I am totally new one to embbed world and i am learning stuff now....i am porting linux on to this and i wan to know is there any other means of debugging the code with out using JTAG
  • [18:17:27] <Beagle1> starting frm loding the UBOOT
  • [18:17:50] <mru> linux is stable, so you probably don't need to do much debugging there

  • [18:44:43] <dirk2> If you have your board rev B4 from digi key, U-Boot should be already in NAND flash
  • [18:46:31] <Beagle1> yeah i am getting it shipped from digi Key this week some time then this would help me.

  • [18:54:42] <dcordes> is there some documentation on the beagle usb? I would like to try the host capabilities

  • [19:00:46] <dirk2> http://www.yoss.de/cgi-bin/yosst.htm?shop=10&direkt=ja&language=2&jump=ZHost should work. I think koen uses it.
  • [19:01:03] <dcordes> ok that's just what I use
  • [19:01:15] <dcordes> but what about the software side? how can I switch to host?
  • [19:01:51] <dirk2> plug in cable and boot koen's uimages
  • [19:01:58] <dcordes> I just booted
  • [19:02:30] <dcordes> I connected the iriver cable and hooked up my usb hub
  • [19:02:31] <dcordes> no voltage
  • [19:03:57] <dirk2> plug in the cable before booting, then boot uimage
  • [19:04:03] <dirk2> do you use a power hub?
  • [19:04:32] <dirk2> for first check replace hub and simply use an usb mouse
  • [19:04:38] <dcordes> before booting ok. no unpowered, I though I had 100mA
  • [19:08:39] <dcordes> dirk2: how can I make uboot automatically initialize mmc and boot with my specified cmdline?
  • [19:09:02] <dcordes> i.e. perform the following commands automcatically:
  • [19:09:06] <dcordes> mmcinit
  • [19:09:10] <dcordes> fatload mmc 0 0x80300000 uImage
  • [19:09:22] <dcordes> setenv bootargs console=ttyS2,115200n8 noinitrd root=/dev/mmcblk0p2 rootfstype=ext2 rw rootdelay=5 nohz=off
  • [19:09:31] <dcordes> bootm 0x80300000

  • [19:31:18] <dcordes> all the cables plus beagle were ok

  • [19:33:52] <dcordes> seems to work
  • [19:34:53] <dcordes> chakie: it must be something between my desktop's onboard serial device, bios, and kernel that are wrong
  • [19:35:26] <chakie> dcordes: something as simple as serial seems to be so non-trivial sometimes :)
  • [19:35:43] <ahu> dcordes: thanks!
  • [19:36:01] <ahu> dcordes: I still have a real serial port here on my pc - which I think means I don't need usb2serial?
  • [19:39:21] <dirk2> dcordes: You should be able to decrease rootdelay to 1 or 2, if you like you can try it. And I'm not sure what the nohz parameter does and if it is necessary
  • [19:40:01] <mru> instead of rootdelay=x, use rootwait
  • [19:40:46] <mru> it causes the kernel to wait for the root device to appear, and proceed immediately when it does

  • [23:08:04] <mru> did you read http://www.angstrom-distribution.org/demo/beagleboard/README.txt
  • [23:08:32] <mru> make sure you have video=omapfb:vram:2M,vram:4M in your kernel command line
  • [23:08:52] <mru> cat /proc/cmdline to check
  • [23:09:20] <dcordes> didn't have the video=omapfb:vram:2M,vram:4
  • [23:09:40] <dcordes> is it normal that I get the panics then?
  • [23:09:59] <dcordes> http://pastebin.com/md5bc2b3 here's the kernel prints I get on the serial after running mplayer
  • [23:11:38] <mru> where did those extra empty lines come from?
  • [23:11:56] * Olipro__ (n=Olipro@unaffiliated/olipro) has joined #beagle
  • [23:12:06] <mru> ah, that would be the alsa bug
  • [23:12:13] <mru> disable audio for now
  • [23:12:18] <mru> or make it use oss
  • [23:13:53] <mru> omapfbplay doesn't play sound at all
  • [23:15:39] * Olipro (n=Olipro@unaffiliated/olipro) Quit (Success)
  • [23:16:35] <dcordes> mru: ok omapfbplay played the video just fine
  • [23:16:50] <dcordes> I tried mplayer -ao oss video.avi and got the same panic
  • [23:17:25] <dcordes> (soc_pcm_open+0x0/0x354) etc

  • [23:19:51] <mru> what sort of video are you playing?

  • [23:21:31] <mru> omapfbplay -f scales to full screen
  • [23:21:43] <mru> -b N tells it to use N MB memory
  • [23:22:11] <mru> more memory gives smoother playback
  • [23:22:31] <sakoman> dcordes: mplayer is crashing due to a known alsa bug.
  • [23:22:47] <sakoman> omapfbplay doesn't do sound, so it won't crash
  • [23:23:37] <mru> not for that reason at least
  • [23:25:06] <sakoman> :-)
  • [23:25:23] <mru> of course my code is perfect
  • [23:25:27] <mru> it's the hardware...
  • [23:28:40] * Olipro_ (n=Olipro@unaffiliated/olipro) Quit (Read error: 110 (Connection timed out))
  • [23:29:31] <dcordes> mru: RIFF (little-endian) data, AVI, 624 x 352, 23.98 fps, video: XviD, audio: MPEG-1 Layer 3 (stereo, 48000 Hz)

  • [23:43:15] <dcordes> sakoman: was the alsa bug fixed already?
  • [23:44:41] <mru> not that I've heard
  • [23:55:18] <dcramer> interesting: I just read that the board is supposed to come with a usb cable
  • [23:55:23] <dcramer> mine didn't ?
  • [23:55:59] <mru> don't you have a usb cable that came with something else?
  • [23:56:22] <mru> you only need the special cable for automatic host/gadget mode selection
  • [23:56:48] <dcramer> well, the challenge of course is finding an otg to female connectore
  • [23:57:00] <dcramer> I don't want to plug it into my computer
  • [23:57:11] <dcramer> I want to plug an ethernet adapter in
