[00:00:34] <Crofton|work> thanks mru
[00:00:56] <mru> the letter varies with ES rev
[00:01:00] <Crofton|work> yeah
[00:01:03] * kanru (~kanru@118-168-239-241.dynamic.hinet.net) has joined #beagle
[00:01:12] <Crofton|work> I still want to know about the missing rev :)
[00:01:16] <Crofton|work> ok
[00:01:20] <Crofton|work> beer thirty for me
[00:01:24] <Crofton|work> gn all
[00:01:30] <Jefro> mekoniak - I haven't tried hot-swapping cards... my guess is that your card isn't working. how does its partition table look? the first partition should be FAT16 or FAT32 with the boot option checked
[00:01:36] <Jefro> nite Crofton|work
[00:02:00] <mru> and mlo needs the damn sector 63 fix
[00:02:02] * tconant (~tconant@68.111.35.226) Quit (Quit: tconant)
[00:02:35] <Jefro> mru is that still an issue? I didn't jump through that hoop when formatting a card for the xM and it worked for me.
[00:02:49] <mru> maybe you got lucky
[00:02:59] <mru> it's still missing from many trees
[00:03:16] <mekoniak> checking now
[00:03:37] <mekoniak> I do get a 60 on serial when I boot with no card
[00:03:45] <mru> then cable is good
[00:05:04] <Jefro> mekoniak - one thing I have also done is to use the know-good card (the xm test card that came with the board), copy all of its data to my host, and then replace uImage as needed. I had some questions about how that card was set up (odd 2nd partition) but I was able to format the 3rd partition and use it for my rootfs.
[00:06:26] * peabody124 (~peabody12@adsl-99-41-234-41.dsl.hstntx.sbcglobal.net) Quit (Quit: peabody124)
[00:06:58] <mekoniak> I'll try that next, I guess. Good idea!
[00:07:26] <mekoniak> mru, the 60 is in the middle of a bunch of garbage. Is that normal?
[00:08:20] * Openfree (~df@61.173.52.3) Quit (Remote host closed the connection)
[00:08:29] <Jefro> yes, that should be ok
[00:08:55] <mru> perfectly normal
[00:09:01] <mru> it's not garbage btw
[00:09:04] <mru> just not ascii
[00:09:09] <Jefro> I'm guessing that the 1st partition on your card is missing some vital yet obscure feature (such as the 63 sectors thing). If using the stock card works, one easy way to copy its partitions is to simply dd the entire card to a file, take it out and put your card in the reader, and then dd it back out. or if you have two readers, dd from one to the other.
[00:09:32] <Jefro> mru LOL

[00:09:58] * dm8tbr (dm8tbr@gw.bfst.de) has joined #beagle
[00:11:49] <mekoniak> what is the non-garbage info? also, what is the 63 sector problem?
[00:13:33] <Jawwad> I dont have the profile.sh on my Fedora 12 so I cant establish the bitbake environment variables
[00:13:43] * peabody124 (~peabody12@adsl-99-41-234-41.dsl.hstntx.sbcglobal.net) has joined #beagle
[00:13:44] <Jawwad> is there any alternatives that I can use?
[00:15:40] <Jawwad> I'm trying to use the omap graphics bin file
[00:16:30] <Jefro> mekoniak - on the FAT partition, geometry has to be set to 255 heads, 63 sectors
[00:17:10] <mekoniak> Jefro, Partition table is 50 cylinder FAT32 partition with boot flag first, then the rest of the card as ext2
[00:17:33] <mekoniak> confirmed 255 heads, 63 sectors
[00:17:48] <Jefro> huh. that sounds like it should work.
[00:18:03] <Jefro> can you compare it to the one that works?
[00:19:31] * ant_ (~andrea@host118-105-dynamic.50-82-r.retail.telecomitalia.it) Quit (Quit: Ex-Chat)
[00:21:22] <mekoniak> doing that now. Also I put on your MLO file. Just put the card in rev-B BB and it booted
[00:23:28] <mekoniak> except for size of partitions, the cards are the same (same size, same geometry, etc)
[00:24:12] <mekoniak> I'll try dding the good card to mine to confirm that my card is OK in the morning
[00:24:54] <mekoniak> Thanks for all your help Jefro, mru, and Crofton!
[00:25:12] <Jefro> cool! glad to help
[00:26:20] <mekoniak> hopefully I can get it figured out tomorrow... may also try a 3rd card or somethign
[00:26:26] <mekoniak> goodnight!

[05:58:36] <mrj101> anyone know what the deal is with pulseaudio on the xM?
[05:59:04] <mrj101> i've read a few forum posts and launchpad bug reports for ubuntu, but i'm running angstrom and their instructions don't work
[05:59:24] <mrj101> i can get audio to work fine by killing pulseaudio, but was wondering if there is a known workaround to get pulseaudio to work
[06:03:00] <cwillu_at_work> mrj101, -> #ubuntu-arm might be more helpful
[06:03:19] <cwillu_at_work> although this is a quite time of day in both channels
[06:04:58] <mrj101> cwillu_at_work: might be, but they may rely on ubuntisms that aren't true on angstrom. those forum posts have people in my same predicament where the ubuntu fix didn't work for them. it's not a big deal, i don't even need audio for the time being. just curious.

[09:23:29] <elduderino> so it's not available anymore?
[09:24:20] <av500> who says so?
[09:25:12] <elduderino> "it was for a long time" -> I understood this as saying that the xM was once available but not anymore.
[09:26:03] <av500> no
[09:26:16] <elduderino> okay.
[09:26:59] <av500> just order one

[09:58:28] <hitlin37> neon:dsp ratio 10ms:60ms
[10:00:20] <hitlin37> i guess dsp no longer means digital signal processing
[10:00:36] <av500> hitlin37: buy the version without dsp then :)
[10:01:02] <av500> and dont trust any benchmark you did not make yourself
[10:02:03] <hitlin37> without dsp...omap 4
[10:02:38] <hitlin37> and yes i need to try those c6 api's...
[10:03:15] <av500> c6 api will not change the dsp processing time
[10:03:21] <av500> only the overhead
[10:04:19] <hitlin37> hmmm....
[10:05:09] <hitlin37> what will be the result when both are at same clock
[10:05:23] <hitlin37> say both at 600
[10:05:44] <aholler> smoke?

[10:06:33] <hitlin37> in his test case neon is at 520 at dsp at 365
[10:06:40] <hitlin37> *and
[10:06:55] * rodrigo_golive (c8116f03@gateway/web/freenode/ip.200.17.111.3) has joined #beagle
[10:07:01] <av500> yes, so
[10:07:04] <av500> ?
[10:07:18] <av500> the dsp at 600 will be faster than at 365
[10:07:43] <hitlin37> yup,but dsp at 600 and neon at 600
[10:07:47] <hitlin37> then
[10:07:58] <av500> neon at 600 will be faster than neon at 520
[10:08:30] <hitlin37> i mean at same frequency...who will be faster
[10:08:55] <hitlin37> or is it implementation dependent
[10:09:19] <av500> if you say that neon vs dsp is 10 vs 60
[10:09:29] <av500> then at 600:600 it will still be neon that is faster
[10:09:40] <av500> what is your point?
[10:10:06] <aholler> he wants to know the answer which is not found in the mentioned thread
[10:10:40] <hitlin37> dsp is signal processing but neon is doing signal processing faster..then whats the point of dsp on bb
[10:13:56] <av500> neon is allegedly doing one thing faster, yes
[10:14:20] <av500> as said, I dont trust any benchmark I did not reproduce myself AND look deeply into it
[10:14:45] <av500> I agree that there is a ton of things than can be wrong or badly configured on the dsp side and that it is not easy to set them up properly
[10:15:08] <av500> hitlin37: and, having a dsp means that you can do stuff at the same time as the main cpu
[10:17:46] <hitlin37> "same time as the main cpu" is always a good idea..but if neon can outperform dsp in dsp calculation...then nobody is going to use dsp
[10:18:42] <hitlin37> plus..what about all the omap3 smartphones out there..anyone is using dsp there
[10:20:26] <av500> of course
[10:21:03] <av500> its mostly used for video encoding/decoding
[10:21:11] <av500> together with the hw accelerators
[10:21:54] <hitlin37> ok..i thought neon is faster for av too
[10:22:06] <av500> you are comparing apples and oranges
[10:22:29] <av500> a large FFT might well be faster using neon
[10:22:33] <hitlin37> no...im comparing apple juice and apple
[10:22:34] <RobotGuy> I prefer to compare apples and blueberries.
[10:22:43] <av500> stuff that does not fit into dsp l1/l2 caches will suck
[10:23:11] <hitlin37> hmmm
[10:23:29] <av500> but, is this 32k fft relevant?
[10:24:05] <av500> hitlin37: and btw, TI is a dsp company, there always has to be a dsp inside...
[10:24:06] <av500> :)
[10:24:22] <av500> once they drop the dsp, all that is left are calculators.

[10:26:07] <av500> so, do the bench for 2k
[10:26:40] <hitlin37> good idea...that way i can learn abt dsp
[10:27:15] <hitlin37> but ti dropped it..ompa4
[10:27:51] <hitlin37> although there's image processing
[10:28:50] <av500> omap4 still has a dsp

[12:14:04] <aholler> but it's handy to have usb-touch-lcd for doing embedded stuff. most embedded boards where you can use linux are offering usb.
[12:14:21] <mnemoc> yes, it sounds very interesting
[12:14:55] <aholler> would be a nice idea to use an archos as usb-lcd ;)
[12:15:32] <aholler> shouldn't be that much to write a gadget driver for that

[12:17:08] <mnemoc> aholler: are these mimo monitors supported by the vanilla linux kernel? or patching and voodoo is needed?
[12:17:17] <av500> there is a driver iirx

[12:19:55] <mnemoc> mimo uses it too?
[12:20:11] <aholler> av500: maybe you could suggest this internally ;)

[13:09:19] <av500> http://code.google.com/p/beagleboard/wiki/BeagleboardRevC3Validation
[13:09:36] <DigiSAS> av500, thanks for link but ive been trhough these steps and nothing
[13:09:46] <av500> revC? XM?
[13:09:53] <DigiSAS> can the beagle produce any validation out of the box wihtou sd card
[13:09:57] <av500> no
[13:09:58] <DigiSAS> RevC4
[13:10:33] <DigiSAS> so am i correct in thinking that i should recieve no output from rs232 if there is no SD card present
[13:10:39] <DigiSAS> ?
[13:10:41] <djlewis> no
[13:10:53] <av500> DigiSAS: that depends on the contents of your NAND
[13:11:09] <djlewis> there would be the 40W
[13:11:09] <av500> but why speculate about that, just shove and sdcard in and enjoy
[13:11:12] <DigiSAS> ive just received this new this morning, what SHOULD be on NAND
[13:11:21] <av500> djlewis: not if there is a mlo in flash

[13:11:30] <DigiSAS> ive tried with SDcard and nothing so im beginning to think board is dead
[13:11:32] <av500> DigiSAS: I dont know
[13:11:39] <av500> ignore the nand
[13:11:45] <djlewis> probably your serial connection
[13:11:48] <av500> and setup an sdcard
[13:11:54] <av500> and check your serial
[13:11:58] <DigiSAS> but i should receive a sound too
[13:12:02] <djlewis> no
[13:12:35] <DigiSAS> if serial was poor then id get sound and s-video test bars no?
[13:12:44] <av500> svideo yes i guess
[13:12:55] <djlewis> with a good u-boot
[13:13:08] <DigiSAS> im just trying to eliminate everything
[13:13:17] <djlewis> currently just a orange screen
[13:13:29] <djlewis> best to use a DVI monitor
[13:13:39] <DigiSAS> im using a hdmi monitor
[13:13:44] <DigiSAS> and black screen
[13:13:49] <av500> DigiSAS: http://www.angstrom-distribution.org/demo/beagleboard/sd-images/2gb/
[13:13:52] <DigiSAS> i tried s-video to my tv and same
[13:14:07] <av500> download a demo image, unzip and dd to your sd card
[13:14:22] <djlewis> takes the mistakes out of the equation
[13:14:28] <djlewis> most anyway
[13:14:32] <DigiSAS> ok
[13:14:37] <jkridner|work> koen: have you seen this craneboard thing from Mistral: https://patchwork.kernel.org/patch/289742/ ?
[13:14:42] <DigiSAS> using dd would rebuild the correct partition map too?
[13:14:43] <av500> use your $20 to buy an sdcard
[13:14:50] <DigiSAS> :D
[13:15:11] <jkridner|work> koen: is there any simple (best practice) steps to follow to add a machine definition for it?
[13:15:29] <av500> ping mistral to do it?
[13:16:16] <jkridner|work> yeah, just want to tell them clearly what to do.
[13:16:55] <jkridner|work> koen: btw, Luca256's patches are on the list now.

[13:22:26] <DigiSAS> gr8 thnx
[13:23:27] <DigiSAS> also in checking my Null Modem cable, should the rx and tx pins be the same on each end. i.e. pin 2 ->pin 2, pin 3->pin3
[13:23:41] <djlewis> no, swap rx tx
[13:23:48] <DigiSAS> or (if memory serves me well) rx -> tx
[13:23:56] <djlewis> null modem is 2-3, 3-2
[13:24:12] <djlewis> correct
[13:24:20] <av500> DigiSAS: 2-3, 3-2
[13:24:37] <av500> and also make sure your 9pin to 10pin adapter is the right one
[13:24:45] <djlewis> good point
[13:24:47] <av500> there are 2 different "styles"
[13:25:09] <DigiSAS> ive made it myself
[13:25:24] <DigiSAS> to at/everex layout (i think)
[13:25:50] <av500> well, use a beep thingy to check that pc rx goes to bb tx and vice versa
[13:25:54] <mru> you need the annoying one
[13:26:15] <av500> everex is the annoying one
[13:26:18] <DigiSAS> beep thingy :P, a continuity tester?
[13:26:24] <av500> yep
[13:26:30] <DigiSAS> i like yr style
[13:26:40] <av500> you can also use a light bulb and mains power
[13:26:49] <av500> disconnect the BB 1st please
[13:26:50] <aholler> so much problems with 3 cables ;)
[13:26:53] <DigiSAS> haha
[13:27:27] <DigiSAS> currently i have IDC Pin 3 -> DB9 Pin 2
[13:27:37] <DigiSAS> IDC Pin 2 -> Db9 Pin 3
[13:27:44] <djlewis> or jumper the ide end pins 2,3 and type on PC , look for echo
[13:27:52] <djlewis> disconect from BB first
[13:28:15] <av500> and disconnect mains power
[13:28:18] <DigiSAS> because my serial cable is straight through, so doing the crossover on the idc
[13:28:25] <av500> should be ok
[13:28:52] <djlewis> I'd rip my PC mainboard apart and do surgery there ;)
[13:29:26] <av500> rip the usb2serial chip apart
[13:29:39] <av500> I bet its only gios internally :)

[14:21:35] <BlInK311> im new to linux and the beagleboard so this may be a stupid question. Is it possible to configure the kernel to boot into a specific program and only run that program? or do i have to boot into a linux os and then run the program?

[14:32:24] <av500> yes, why?
[14:33:55] <BlInK311> basicly, im trying to make a program that'll stream video through the camera port right to a screen. and then beable to record this video at the same time as streaming. however, id like to have the board go directly into streaming the video, without having to manually start the program from a desktop or anything
[14:35:12] <mgrundy> BlInK311: a better way to approach it is have it start from an init script
[14:35:35] <mgrundy> just peruse /etc/init.d for examples of other things starting
[14:35:58] <jannau> if it's a X11 application, a xdm with autologin and autostart or xsession is probably easier
[14:36:27] <av500> BlInK311: ok, so you asked the wrong question

[14:38:36] <topfs2> btw koen awesome movie on the homepage! just noticed it :)
[14:38:55] <av500> BlInK311: wouldnt it be more important to actually write the SW instead of worrying how to autostart it?
[14:39:23] <koen> topfs2: which movie?
[14:39:43] <topfs2> I used a chuck episode
[14:39:48] <topfs2> Can download big buck and try
[14:40:07] <topfs2> 1080p in 480p was at about 7fps but doesn't show much since its per fragment
[14:40:47] <topfs2> the one in 720 was in about 10fps (presented in 480)
[14:41:01] <topfs2> but I'm pretty sure thats vnc and actual decode thats problematic

[16:17:24] <koen> I wonder where people find the time to rebuild QT

[16:21:36] <jkridner|work> ah! I was loading the wrong file. toolchain *did* fix my issue.
[16:21:58] <jkridner|work> k, I'll cherry pick at least one of them now. I raised my objections with the second one.
[16:22:59] <jkridner|work> wow, the load time is SOOO much faster. :)
[16:23:01] <holmes123> So i'm curious, when you config your u-boot for video, say "video=omapfb:vram:2M,vram:4M" or whatever, is there any other options than omapfb?
[16:23:29] <av500> uboot does no video
[16:23:44] <jkridner|work> yeah, it doesn't have the color update yet...
[16:23:54] <jkridner|work> I was just trying to get the old patches rebased first.

[16:24:11] <holmes123> hmm
[16:24:15] <jkridner|work> oops. :)
[16:25:23] <holmes123> Say I wanted to use new display drivers, would I somehow attach them to the omapfb?
[16:25:32] <mrj101> av500: doesn't he mean setting the kernel bootargs that are passed from u-boot?

[16:25:46] <av500> holmes123: read DSS docs
[16:25:49] <holmes123> I've been looking at the omap DSS documenation and I'ma bit confused..
[16:25:55] <av500> in linux/docu..../
[16:26:05] <JPohlmann> Hi! I'm trying to boot a Linux/MeeGo image from an SD card on the beagleboard. Something goes wrong though; on the minicom I only receive weird symbols (characters that cannot be displayed) and on the attached screen I see nothing. Any ideas?
[16:26:27] <av500> and you can boot e.g. angstrom?
[16:26:48] <holmes123> well actually I'm being rather silly and trying to do many things at once..
[16:26:51] <JPohlmann> I knew I should've tried with something easier first ;)
[16:26:54] <holmes123> I am running 0xdroid's android port
[16:26:55] <mrj101> JPohlmann: is your serial port configured correctly? i.e. 115200n1?
[16:27:31] * kimitake_idle is now known as kimitake
[16:27:36] <mrj101> JPohlmann: i get only weird symbols when either I have no SD card plugged in or it can't find MLO (x-load)
[16:27:49] <JPohlmann> mrj101: setenv bootargs 'console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 ro rootwait omapfb.mode=dvi:800x600-16@60
[16:28:11] <JPohlmann> that's what I have in the boot loader file
[16:28:37] <JPohlmann> The minicom is configured for 115200 8N1
[16:28:43] <mrj101> minicom config sounds right
[16:29:00] <mrj101> those are the kernel bootargs though, you're not getting anywhere near u-boot loading are you?

[16:29:43] <mrj101> what beagleboard rev do you have?
[16:29:56] <JPohlmann1> Damn, I was disconnected, sorry
[16:30:00] <JPohlmann1> minicom config sounds right, that's what I received last
[16:30:02] <JPohlmann1> C4
[16:30:07] <mrj101> (11:29:00 AM) mrj101: those are the kernel bootargs though, you're not getting anywhere near u-boot loading are you?
[16:30:11] <mrj101> (11:29:25 AM) mrj101: the process is: OMAP boot ROM -> x-load (binary is called MLO) -> u-boot -> kernel
[16:30:30] <JPohlmann1> Hmm, I don't now how far it goes
[16:31:09] <holmes123> So av500, I have read the DSS documentation
[16:31:16] <JPohlmann1> mrj101: When I press reset + user button then there is no output at all in the minicom. If I press the same combination again, I get the weird characters again
[16:31:28] <av500> holmes123: damn, I thought I could hold you off longer
[16:31:28] <JPohlmann1> So it's doing something at least ;)
[16:31:29] <holmes123> but I'm not really sure how a new display driver I am trying to use would fit into that mix
[16:31:32] <holmes123> haha
[16:31:37] <av500> read it again
[16:31:45] <holmes123> I mean I've read it over and over for like 3 days haha

[16:32:02] <holmes123> nooooo, haha
[16:32:25] <av500> well, look into the kernel source, there are a lot of lcd drivers already
[16:32:29] <djlewis> av500: i was away, " MotherLoada", god one :)
[16:32:29] <holmes123> basically I've rebuilt the 0xdroid kernel with some drivers I want to use
[16:32:29] <av500> see if you cna use one
[16:32:37] <av500> or reuse one and tweak
[16:32:40] <djlewis> s/god/good
[16:32:47] <JPohlmann1> mrj101: I'll try the angstr??m beagle board demo image next
[16:32:51] <djlewis> later, on the road again :P
[16:34:17] <holmes123> So I guess what I need to learn is how to change which display drivers are being used?
[16:34:28] <av500> guess so
[16:34:35] <av500> look at other board files
[16:34:49] <av500> e.g for boards that have lcd and not dvi output
[16:35:08] <holmes123> ah
[16:35:13] <holmes123> where woudl be the place to look?

[16:57:51] <JPohlmann1> It says "D-Sub null modem cable" on the invoice from the shop
[16:58:10] <JPohlmann1> But maybe that cable is not the right one and that's why my minicom displays weird characters only?
[17:01:18] <av500> JPohlmann1: normal or not, in the end you need to have PC TX connected to BB RX and vice versa
[17:01:25] <av500> that is all that counts

[17:05:42] <av500> coz in many, the last guy who knews what it was good for is retired

[19:07:12] <djlewis_> yup, yup, yup, ungh huh ungh huh, yup, yup, yup
[19:07:32] <mrj10> but think of all the children of level shifter designers you've put through college!
[19:07:35] <DaveDavenport> ugh damn why doesn't this stupido kernel work
[19:08:17] <ds2> yes, and all those power designers
[19:08:42] <mrj10> yeah, power supply designers too
[19:08:44] <ds2> 7805 was a nice power supply now we have to deal with PMICs

[19:18:31] <DaveDavenport> bitbaked it.. fine.
[19:18:33] <mrj10> i tried as well, and most things worked, but never could get X to work. i think most of the TI drivers and stuff don't work with some of the new kernel interfaces
[19:18:36] <mrj10> yeah, same
[19:18:44] <DaveDavenport> I do not get any serial console
[19:18:46] <DaveDavenport> it just sais
[19:18:49] <mrj10> oh
[19:18:56] <digisas> aholler: so is it fair to say the intel is fine when u are using a straight serial cable?
[19:19:00] <mrj10> says what?
[19:19:05] <mrj10> i fixed that problem on mine
[19:19:05] <DaveDavenport> http://www.spinics.net/lists/linux-omap/msg34226.html
[19:19:07] <DaveDavenport> that
[19:19:09] <DaveDavenport> or so
[19:19:18] <DaveDavenport> Uncompressing Linux... done, booting the kernel.
[19:19:18] <mrj10> yeah, i know what the problem is
[19:19:20] <DaveDavenport> nad nothing
[19:19:22] <DaveDavenport> cool
[19:19:24] <DaveDavenport> what is it
[19:19:32] <aholler> digisas: don't know
[19:19:49] <DaveDavenport> after spending almost a week waiting on the borked icore 7 to compile it
[19:19:54] <DaveDavenport> well 4 days
[19:19:59] <mrj10> somehow the OMAP's on-board UARTs usurp the normal ones
[19:20:17] <DaveDavenport> so it is under another id?
[19:20:21] <mrj10> so there might be a slightly nicer way to do it, but i don't need those UARTs at all, so i disabled them in my kernel config
[19:20:27] <mrj10> as far as i could tell they weren't there at all
[19:20:39] <mrj10> you have to disable something like CONFIG_SERIAL_OMAP
[19:20:42] <DaveDavenport> aah ok
[19:20:53] <mrj10> which in turn requires that you disable CONFIG_OMAP2_TYPICAL or somesuch
[19:21:14] <mrj10> which isn't a big deal, look at what other options CONFIG_OMAP2_TYPICAL enables and make sure you have all the rest of them enabled still
[19:21:19] <mrj10> things like NEON
[19:22:06] <mrj10> when i just disabled CONFIG_SERIAL_OMAP in the defconfig file, it got re-enabled because CONFIG_OMAP2_TYPICAL was still on.
[19:22:18] <mrj10> i doubt you'll get DVI out, but most other things should work fine

[19:23:01] <digisas> to n00b like me, how can i flash any led on b.board? is there a port? im imaging i can send high or low?
[19:23:17] <DaveDavenport> mrj10: yes
[19:23:53] <ds2> digisas: look at the Beagle Board 101 tutorial
[19:23:54] <DaveDavenport> do I need to disable SERIAL_CORE?
[19:23:55] <ds2> it does exactly that
[19:25:09] <DaveDavenport> a well lets try it

[19:25:52] <mrj10> sorry, that was for DaveDavenport
[19:25:57] <mrj10> do you have an xM?
[19:26:03] <digisas> in the 0xdroid for beagle, do you get a serial console. mine does nothing after Loading Kernel(i dont have monitor, just terminal)
[19:26:46] <mrj10> i should probably respond to that mailing list post you linked with my hacky fix, seems like several people have been stumped.

[19:32:37] <digisas> we did dj, thanks, but im trying to get os installed
[19:32:52] <djlewis_> oh, step two of the manual
[19:32:59] <digisas> haha
[19:33:10] <djlewis_> ;)
[19:33:27] <holmes123> I just followed their directions to load the SD card with the 3 files they need (including their installer which automates everything)
[19:33:41] <digisas> me too but i get a mount error
[19:33:52] <djlewis_> yeah, the sd maker on DEMO works well.
[19:34:12] <digisas> ive got demo on but its not mounting the mmc
[19:34:31] <digisas> mmcblk01
[19:34:40] <digisas> p1
[19:35:02] <digisas> so the audio demo cannot write the wav etc
[19:35:20] <djlewis_> sounds like a funk'd MLO, u-boot.bin along in there.
[19:35:43] <djlewis_> digisas: you are getting it booted ot not?
[19:36:03] <digisas> theres an MLO file on card and i get a prompt and can get in as root
[19:36:30] <djlewis_> so you are looging onto linux then.
[19:36:33] <digisas> but tried mounting mmc to /dev/mmc
[19:36:46] <digisas> yes i have booted in a fashion sorry
[19:36:55] <djlewis_> its already mounted
[19:37:08] <djlewis_> type df -ah
[19:37:08] <digisas> ah correct
[19:37:10] <djlewis_> or mount
[19:37:31] <digisas> does it mount as /dev/card?
[19:37:41] <holmes123> oh i dunno if this is remotely helpful but did you see that for rec 0x5 they tell you to rename uImage.bin to just uImage?
[19:37:53] <digisas> ahhhh
[19:38:16] <holmes123> I am looking for where it says that.. but I know it does somewhere
[19:38:17] <digisas> on 0xdroid i got a uImage error.
[19:39:02] <digisas> i tried renaming to *-beagle.* too
[19:39:38] <digisas> as in the config it addresses files with a "-beagle" suffix

[22:44:18] <djlewis_> hmm, so our google groups is going to block uploading and changing of files soon.
[22:45:48] <_av500_> ?
[22:48:33] <djlewis_> http://groups.google.com/group/beagleboard top of page in red
[22:52:08] <djlewis_> most likely wont effect posting
[22:52:20] <_av500_> wont
[22:52:28] <_av500_> did we have any files there?
[22:52:57] <dm8tbr> that's just for this wiki-like thing as far as I understood (I also run an googlegroup)
[22:53:07] <CMoH-notebook> hello. i'm trying to get some advice on wether it is possible to set up a gigabit router with the beagleboard
[22:53:21] <Crofton|work> it isn't
[22:53:31] <dm8tbr> looks like they're just downsizing it to an mailinglist with web-access
[22:53:38] <mru> the only interface on the beagle with gigabit rates is the dvi...
[22:53:38] <_av500_> xm?
[22:53:44] <CMoH-notebook> Crofton|work, not even with the new xm one?
[22:53:55] <mru> what exactly do you want to do?
[22:53:55] <_av500_> xm is 100
[22:54:06] <mru> build a router?
[22:54:18] <_av500_> route a builder?
[22:54:18] <mru> then get a routerboard from mikrotik
[22:54:29] <CMoH-notebook> mru, no, just move from my pc-based with lots of fans in it to a quiet beagleboard
[22:54:58] <mru> where does gigabit enter the picture?
[22:55:04] <CMoH-notebook> but inside my home i have a gigabit network
[22:55:06] <_av500_> stage left
[22:55:36] <dm8tbr> is your upstream gbit?
[22:55:37] <CMoH-notebook> i've read a bit on forums but i got nothing conclusive; my plans were to move my current file server to a beagleboard
[22:55:39] <kblin> CMoH-notebook: there's passively cooled routerboards with mutliple gigE ports
[22:55:48] <mrj10> Oh, do you mean is it possible to hook the xM up to a gigabit router?
[22:55:56] <mru> beagle does _not_ make a good file server
[22:55:58] <mrj10> most gigabit routers have 10/100/1000 ports
[22:56:22] <CMoH-notebook> mru, it's for personal use - nothing fancy
[22:56:34] <kblin> dm8tbr: doesn't matter, if you're streaming e.g. video locally your LAN speed matters, the rest not so much
[22:56:48] <mru> it's still a poor choice
[22:56:55] <mru> there are much better systems for that
[22:57:04] <mru> like anything with sata and gbe
[22:57:04] <_av500_> nothing in the XM can handle a gigabit anyway
[22:57:11] <mru> _av500_: dvi...
[22:57:13] <CMoH-notebook> well, i thought i'd just get a quick answer like "yes it's possible" or "no, don't even think about it"
[22:57:14] <kblin> CMoH-notebook: I can recommend the dockstar if you want arm, gigabit and fileserver
[22:57:15] <mru> but that's one-way
[22:57:35] <dm8tbr> kblin: he didn't mention NAS, only routing at that point
[22:57:38] <_av500_> choyou can connect it, it will run at 100
[22:57:39] <mru> CMoH-notebook: then the answer is don't even think about it
[22:57:41] <_av500_> oops
[22:57:46] <mrj10> it's possible, but it will almost surely perform worse than what you used now
[22:57:47] <_av500_> CMoH-notebook:
[22:58:56] <kblin> in my tests the dockstar is faster than a sheevaplug (which surprises me, the hardware seems pretty similar), the PSU is less stupid and it does about 28MB/s over samba
[22:59:21] <CMoH-notebook> but to detail, slowly along the time i've used older computers as servers in the closet. i've started working with the beagleboard and thought i could replace the noisy power-hungry PCs that rotated through that closet with a beagleboard with an USB drive
[22:59:21] <djlewis_> get a new atom board
[22:59:34] <kblin> just make sure to not connect it to the internet before you can ditch the stupid OS on it
[23:00:03] <kblin> oh, and the dockstar retails for as low as $25
[23:00:21] <_av500_> CMoH-notebook: usb2sata is 20-25MB/s max
[23:00:23] <CMoH-notebook> last time i cleaned that computer... well... the idea shined to me so i started listing what i would need and besides this particular gigabit question...
[23:00:30] <_av500_> usb2eth wont be much faster
[23:00:40] <_av500_> on the BB
[23:00:44] <CMoH-notebook> so it's nothing professional, supporting zillions of users or such :D
[23:00:56] <CMoH-notebook> thanks kblin - i'll google it in a sec
[23:01:25] * javaJake (~javaJake@unaffiliated/javajake) has joined #beagle
[23:01:49] <kblin> _av500_: my C4 beagle does ~ 23 MB/s fileserving from USB hdd
[23:02:13] * heathkid (~heathkid2@108.114.99.241) has joined #beagle
[23:02:13] <kblin> right in your range :)
[23:02:23] <djlewis_> CMoH-notebook: gigabit across the board is expensive. Ramdrives come to mind
[23:02:35] <djlewis_> then ther is the sata port bottle neck
[23:03:11] <kblin> I didn't get around to benchmark my hawkboard yet, I still need to get a kernel up on that box
[23:03:25] <CMoH-notebook> well, besides the performance issues i'll have to investigate, where could i connect a gigabit board to the beagle?
[23:03:38] <mru> you can't
[23:03:45] <_av500_> kblin: that would mean actually 23+23 over usb
[23:03:48] <mru> beagle has only usb
[23:04:03] <mru> not good for file serving
[23:04:17] <kblin> _av500_: yeah, got an asix usb-eth chipset
[23:04:34] <_av500_> CMoH-notebook: as stated, 25mB/s is the max
[23:04:46] * heathkid (~heathkid2@108.114.99.241) has left #beagle
[23:04:46] <mru> pretty poor, in other words
[23:05:22] <kblin> _av500_: usb does 480Mb/s, which is well above the 100Mb/s ethernet does
[23:05:34] <_av500_> kblin: in theory
[23:05:37] <mru> that's the wire speed
[23:05:37] <_av500_> not on omap3
[23:05:40] <djlewis_> what is the byte speed value for actual data in a gigabit transfer under ideal conditions?
[23:05:58] <mru> 100MB/s or so
[23:06:00] <djlewis_> is it the 25mB/s number youu gave?
[23:06:01] <kblin> djlewis_: what protocol?
[23:06:02] <CMoH-notebook> heh, i'll have to benchmark my current transfer rate with the PC and see if i am above the 25mb/s
[23:06:12] <mru> djlewis_: bitrate/10 is usually a good approximation
[23:06:21] <djlewis_> dunno, i just know you wont achieve a gigabit anyway.
[23:06:32] <djlewis_> packet overhead
[23:06:33] <kblin> djlewis_: a dumb protocol like ftp gets pretty close
[23:06:35] <CMoH-notebook> is 25mb/s a CPU bottleneck? or merely a calculus on the USB bandwidth
[23:06:43] <mru> remember that usb is half duplex
[23:06:53] <_av500_> CMoH-notebook: more or less
[23:06:54] <kblin> nfs/cifs not so much
[23:06:57] <djlewis_> transactions, cheap copper stretched out in the house
[23:07:25] <_av500_> djlewis_: stretching eth cables is unwise
[23:07:30] <djlewis_> hehee
[23:07:52] <mru> yeah, you might get 9-bit bytes coming out the other end
[23:07:54] <kblin> regardless of what mru is saying, I've got a handful of embedded boxes serving files from USB hdds
[23:07:54] <djlewis_> well there is more to achieving gigabit speed than just running cable and adding cards and switches
[23:08:03] <CMoH-notebook> _av500_, what do you mean with "more or less"
[23:08:05] <CMoH-notebook> ?
[23:08:06] <mru> which is of course good if you want to interface with a pdp
[23:08:20] <_av500_> CMoH-notebook:
[23:08:20] <mru> kblin: it's obviously _possible_
[23:08:24] <mru> it's just not a good idea
[23:08:33] <kblin> depends on what you need
[23:08:37] <_av500_> CMoH-notebook: well, you will not get 480mbit/t on the omap3
[23:08:39] <mru> not when there are cheap boards with sata and gbe builtin
[23:08:44] * djlewis_ is heading home.. :)
[23:08:45] <kblin> I wouldn't run a computing cluster off it
[23:08:59] <_av500_> since nothing in the omap3 can handle that speed

[23:09:25] <_av500_> its a chip for mobile phones
[23:09:27] <CMoH-notebook> what bout the xm?
[23:09:32] <_av500_> same
[23:09:45] <mru> the chip has exactly the same interfaces
[23:09:47] <_av500_> CMoH-notebook: if you can live with 25MB/s use it
[23:09:57] <kblin> mru: truth be told, I've yet to see a cheap board that gets above 700Mbit iperf on gigE
[23:10:09] <mru> still beats usb
[23:10:31] <ds2> there is another cortex-a8 with internal SATA, IIRC
[23:10:37] <CMoH-notebook> okay; thanks too all for your time and answers - i'll have to think about all this and well, decide what to do :)
[23:10:38] <mru> of course there is
[23:10:51] <kblin> hawkboard has sata and 10/100 ethernet
[23:10:53] <mru> there are a zillion cortex-a8 chips
[23:10:57] <ds2> from TI
[23:11:03] <mru> that too
[23:11:08] <ds2> =)
[23:11:15] <kblin> that's L138 or something
[23:11:23] <_av500_> not a8
[23:11:24] <mru> that's hawk
[23:11:26] <ds2> no, the L138 is ARMv5 IIRC
[23:11:36] <mru> L138 is an arm926

[23:11:43] <_av500_> yes, its a davinci in disguise
[23:12:03] <ds2> but then look alike OMAP3s show up under the davinci name too ;)
[23:12:10] <_av500_> yes
[23:12:14] <_av500_> stupid ti naming
[23:12:16] <mru> the DM37xx
[23:12:24] <_av500_> almost as stupid as intel
[23:12:53] <_av500_> i7 is quad core unless it is 2 or 6
[23:13:14] <ds2> who's going to be at Techcon?
[23:13:16] <kblin> ARM926EJ-S Core
[23:13:24] <kblin> is what the manual says
[23:13:25] <ds2> ARMv5
[23:13:33] <kblin> oh?
[23:13:56] <_av500_> kblin: arm arch version vs arm model number

[23:14:06] <_av500_> endless fun to mix up
[23:14:12] <kblin> I wonder how people run ubuntu 9.10 on the hawkboard then
[23:14:20] <_av500_> "omg, my omap3 has an ARM7..."
[23:14:21] <mru> poorly
[23:14:30] <ds2> for the next trick, discuss chips with both ARMv7 and ARM7's:D
[23:14:40] <kblin> ah, wait..
[23:14:49] <kblin> not at all :)
[23:14:58] <ds2> but your omap3 probally does have an ARM7 in it ;)
[23:15:15] <_av500_> kblin: the hawk arm9 will rather roll over and die than run ubuntu
[23:15:36] <ds2> problem is ARM9's can be either ARMv4 or ARMv5
[23:15:58] <mru> as can arm7
[23:16:02] <_av500_> ds2: its not a problem for me
[23:16:10] <ds2> which arm7 core is a v5?
[23:16:31] <kblin> _av500_: yeah I just saw the 9.10 instructions actually tell you how to build a 9.04 rootfs
[23:16:33] <mru> arm7ej-s for sure
[23:17:00] <ds2> didn't know there was an arm7ejs; the TDMI's seem to abound
[23:17:26] <_av500_> google knows about it
[23:17:33] <_av500_> so it must be true
[23:18:11] <ds2> is that like finding out the there are cortex based PXA's by google? :D
[23:18:27] <_av500_> http://www.flickr.com/photos/35547713@N02/4215334659/
[23:18:33] <kblin> in any case, if you do want an arm-based file server, the dockstar is the best offer out there right now
[23:18:41] <mru> ds2: arm.com knows of it too
[23:18:51] <_av500_> kblin: what speed do you get?

[23:21:15] <_av500_> kblin: from what drive? the usb?
[23:21:32] <kblin> er, nfs and smb, not ftp
[23:21:46] <kblin> ftp was slower for some reason I didn't bother to debug
[23:21:51] <_av500_> but dockstar has no sata, no?
[23:21:57] <kblin> that's from a USB drive
[23:22:01] <kblin> no
[23:22:07] <_av500_> so, not much faster than your BB then
[23:22:15] <_av500_> 23vs 28
[23:22:24] <ds2> but it probally has iWmmx
[23:22:31] <_av500_> this one not
[23:22:33] <kblin> but it costs only 25 bucks
[23:22:45] <_av500_> true, mine cost the same :)
[23:22:56] <_av500_> sitting unused ever since
[23:23:17] <kblin> so if you don't need all the fancy dvi and audio ports, and need more than one usb port, the dockstar is better
[23:23:31] <_av500_> right, as a file server
[23:23:39] <kblin> yeah

[23:24:08] <kblin> if you want gui or sound, it won't help
[23:24:11] <_av500_> you could hide the dockstar pcb under the beagle
[23:24:27] <kblin> and 128 megs of ram isn't all that much
[23:24:35] <ds2> does the dockstar have USB device support?
[23:24:40] <_av500_> no
[23:24:44] <kblin> no
[23:24:45] <kblin> it
[23:24:58] <kblin> 's basically a sheevaplug with less ram and a better CPU
[23:25:03] <_av500_> ds2: so i2c it is :)
[23:25:15] <ds2> I'll stick with SPI
[23:25:26] <ds2> easier on the level converters
[23:25:27] <kblin> you can solder on some wires to get a serial port
[23:25:35] <_av500_> kblin: guess what i did 1st
[23:26:28] <kblin> I just didn't brick mine :)
[23:27:22] <kblin> and because I knew about the online update auto-bricking, I didn't even have to sign up with that pogoplug service to re-open ssh
