  • [00:50:17] <davr> obviously, since they didn't have enough patience to install a proper IRC client in the first place :P
  • [00:50:23] <jkridner> what is the command line to generate the right diff format for OE?
  • [00:52:06] <jkridner> I'm looking to do a bit of a point fix on how freetype's ./configure detects if it is running from the source directory.
  • [00:52:42] <jkridner> I was planning to touch a file in the source directory and test for it to exist. pwd doesn't work great with symlinks.
  • [00:54:44] <Crofton> diif of what?
  • [00:57:19] <jkridner> I guess 'diff -u' is fine.
  • [00:57:45] <jkridner> I've been using 'git diff' to make diffs for patch. I needed to figure out how to make a new patch.
  • [00:58:51] <vlad_> is there really no version of gdb that can inspect vfp registers?
  • [00:58:59] <vlad_> because that is quite sadmaking
  • [00:59:13] <davr> re: pwd & symlinks...does 'pwd -P' help any?
  • [01:00:11] <mru> vlad_: that gdb sucks?
  • [01:00:19] <vlad_> mru: yes, but, this can't be that hard! :)
  • [01:01:22] <vlad_> hm, I have gdb 6.6
  • [01:01:28] <vlad_> I wonder if gdb 6.8 is any better here
  • [01:03:00] <jkridner> davr: hmmm.... that does seem like a better fix.
  • [01:03:29] <davr> i'm not sure on what exactly your problem is (and I don't really care to find out, it being autoconf stuff :P )
  • [01:03:44] <davr> but i know that pwd -P shows the true path, after symlinks are resolved
  • [01:04:21] <jkridner> there were some stupid tests to find out if the script was being run from a demo directory or from the actual source directory.
  • [01:04:41] <ds2> ewwwww OE
  • [01:04:44] * ds2 runs
  • [01:04:53] <jkridner> it was an ugly hack to being (where the ./configure script manually output a Makefile, stomping over the actual Makefile).
  • [01:05:09] <jkridner> OE fixes the problem though, in an automated way.
  • [01:05:29] <jkridner> I could have easily run into this problem trying to build the package w/o OE.
  • [01:05:40] <jkridner> the problem shows itself when I do a simple ./configure.
  • [01:05:44] <ds2> *nod*
  • [01:05:51] <ds2> configure/autoconf/libtools are plain evil
  • [01:06:05] <jkridner> hurray, it builds. :)

  • [01:09:02] * calculus is only joking
  • [01:09:02] <jkridner> I've heard a lot of talk about robotics, media centers, auto PCs.
  • [01:09:23] <calculus> software defined radio is another
  • [01:09:25] <KaiForce> i was thinking media center, slimserver perhaps
  • [01:10:08] <KaiForce> are there nice cases available for it ?
  • [01:10:16] <ds2> beagle is the right size for an auto PC and a DVI makes a good display extender to allow the MB to sit in a safe place ;)
  • [01:10:35] <KaiForce> i dig DVI, I think high powered thin client device
  • [01:10:46] <calculus> some are using it to develop for the pandora gaming system (they use the same omap chip)

  • [01:12:04] <calculus> hmm... there used to be two different cases for sale
  • [01:12:09] <jkridner> I need to find some standoffs to use and my serial port screws didn't quite reach through the thickness.
  • [01:12:30] <jkridner> not sure what happened to the "bent" version (2 parts, instead of 6).
  • [01:12:39] <calculus> and is that the right serial cable?
  • [01:12:58] <KaiForce> jkridner thanks for the link
  • [01:13:02] <jkridner> the dove-tails fit snug, but glue would still be required for places where you'd knock it around.
  • [01:13:29] <ds2> think it would look better w/o the dove tails
  • [01:13:33] <jkridner> I wish that he did real dove-tails instead of 90 degree angles.
  • [01:13:47] <jkridner> the dove tails are functional.
  • [01:14:10] <calculus> the second case that I saw, was one without dove tails
  • [01:14:13] <jkridner> the version that isn't there anymore didn't have the dove-tails. not sure why it was taken down.
  • [01:14:17] <ds2> plastic and dove tails just don't go together
  • [01:14:18] <calculus> doesn't seem to be offered anymore
  • [01:15:06] <jkridner> I saw a prototype of the other version at LinuxWorld, but it didn't quite fit snug.
  • [01:15:25] <jkridner> it would have required a bit more dexterity to glue it together.
  • [01:15:30] <calculus> you mean the fruitcake tin?
  • [01:15:36] <calculus> :P
  • [01:15:37] <jkridner> hehe, not that one!
  • [01:15:44] <jkridner> that one was nice too!
  • [01:15:47] <ds2> eh?
  • [01:15:54] <jkridner> not nearly as nice as this one though!
  • [01:16:05] <ds2> make an aluminum block as a jig and glueing is trivial
  • [01:16:28] <ds2> the bad thing about acrylic is it scratchests at the mere site of anything :(

  • [08:18:41] <mru> not so much
  • [08:18:53] <Agiofws> whats an alternative ?
  • [08:19:01] <mru> a usb ethernet dongle
  • [08:19:04] <koen> khasim: zcat /proc/config.gz on a working image

  • [08:35:53] <guillaum1> "Please provide the names of the 2 individuals by tomorrow or this order will be cancelled"
  • [08:35:53] <guillaum1> Do you get the same ?
  • [08:36:16] <valhalla> the first part of the question yes
  • [08:36:24] <valhalla> the second i don't know
  • [08:36:33] <ldesnogu> guillaum1: tell them it's for nuclear weapon modelling
  • [08:36:53] <Agiofws> "Is this part going" what part ? you ordered a board ?
  • [08:36:59] <Agiofws> LOL
  • [08:37:10] <guillaum1> Agiofws: yeah :-)
  • [08:37:11] <ldesnogu> more seriously my board was sent by someone who ordered it from the US ;)
  • [08:37:30] <valhalla> well, we were thinking about using it on our small robot that we plan to use to conquer the world
  • [08:37:36] <Agiofws> oh so he sent it to you by post ...
  • [08:37:39] <valhalla> but i suppose we won't be able to do so :)
  • [08:38:04] <Agiofws> i think it could make a very good bomb mechanism i guess
  • [08:38:16] <Agiofws> you could cron job it or something
  • [08:38:17] <Agiofws> :)
  • [08:38:26] <zuh> "Yes, I'm going to use the beagle as a guidance system for oversea missiles with nuclear warheads. Is that a problem?"
  • [08:38:37] <Agiofws> LOL
  • [08:38:37] <valhalla> a bit on the expensive side to just use as a timer and let it explode :D
  • [08:39:23] <Agiofws> nah a cron job ... or even login to it via ssh ... and setting it off is more hackarish ...

  • [13:17:42] <geraint> I'm thinking that my hanging problems might be the C70 capacitor thing. Do all the kernels people are flinging around use the MPU timer to avoid the problem, or has everyone just unsoldered C70?
  • [13:18:17] <koen> latest OE kernels use a different 32khz source
  • [13:18:26] <denix> I wouldn't mind overwriting it, but AFAIK overlay (i.e. BB collections) cannot help here with the conf file. Am I right?

  • [18:19:18] <robclark> not quite as evil, but almost
  • [18:19:41] <robclark> really just amounts to modifying the non-instruction parts of the code page
  • [18:19:57] <mru> in what manner?
  • [18:20:41] <robclark> actually an idea for very low overhead code coverage... single instruction to log branch taken

  • [18:49:35] <bennry> hi guys, I'm trying to get the filesystem that Angstrom released into Flash.
  • [18:49:54] <bennry> I've tried to use this method http://www.sakoman.net/omap3/flash%20procedure.txt and Kermit, but I can't get that to work.
  • [18:50:07] <bennry> so a.) what is the recommended terminal emulator to use to do that?
  • [18:50:21] <jkridner|work> bennry: I've been playing with ways to do that
  • [18:50:31] <bennry> b.) How can I get a 160MB file from SD Card to Flash in u-boot?
  • [18:50:45] <bennry> or should I boot linux and move it to the /dev/mdt4 after it's been mounted?
  • [18:50:49] <bennry> I don't know.
  • [18:51:03] <jkridner|work> instead of programming the flash with u-boot and the JFFS2 image, I've been putting the .tar.bz2 image onto an SD card and using a ramdisk image to do the programming.
  • [18:51:28] <jkridner|work> I prefer booting Linux and leaving the SD card formatted as FAT.
  • [18:51:38] <NishanthMenon> jkridner|work - i dont know if ukermit in http://code.google.com/p/omap-u-boot-utils/ will help
  • [18:51:52] <bennry> so, I have the filesystem uncompressed on an ext2 partition on the SD card.
  • [18:52:19] <jkridner|work> bennry: k, if you already have that, you can use mkfs.jffs2 from the root of that partition.
  • [18:52:28] <jkridner|work> mkfs.jffs2 -o /dev/mtdblock4
  • [18:52:40] <jkridner|work> do that from the root of that partition.
  • [18:53:05] <bennry> but the mkfs.jffs2 command doesn't exist on the angstrom distro for beagle board.
  • [18:53:10] <bennry> should I use what you guys released?
  • [18:53:17] <ds2> or just flash_eraseall /dev/mtd4; mount -t jffs2 /dev/mtdblock4 /mnt; tar -C /mnt -xvzf /path/to/tgzfile;umount /mnt
  • [18:53:19] <bennry> the busybox 8M image?
  • [18:53:25] <jkridner|work> you can get it easily with 'opkg install mtd-utils; opkg install mkfs-jffs2'
  • [18:53:32] <ds2> no need for mkfs.jffs2
  • [18:54:06] <jkridner|work> I've been doing the method mentioned by ds2, actually, just using a .tar.gz.
  • [18:54:11] <bennry> ok, I'll try the non-mkfs.jffs2 first and let you guys know how things worked out.
  • [18:54:16] <bennry> ok.
  • [18:54:21] <jkridner|work> but, if you have the whole system mounted, you can use mkfs.jffs2.
  • [18:54:27] <ds2> tar.gz files don't always work nicely on FAT
  • [18:54:36] <jkridner|work> you'll need mtd-utils for 'flash_eraseall'.
  • [18:54:47] <jkridner|work> ds2: how so?
  • [18:54:49] <bennry> thanks guys
  • [18:54:54] <ds2> if you don't have flash_eraseall, use u-boot
  • [18:55:16] <ds2> jkridner|work: tar.gz assumes you have LFN support; basic FAT doesn't
  • [18:55:25] <jkridner|work> vfat then.
  • [18:55:28] <ds2> that's why they went to .tgz back in the sls days
  • [18:55:57] <ds2> .tgz is the exact same thing; it just avoids the LFN issue all together
  • [18:56:09] <bennry> no USB hub connection, hence no internet for opkg.
  • [18:56:10] <bennry> shit.
  • [18:56:14] <bennry> er..sorry,
  • [18:56:21] <bennry> I'll have to do the .tgz way.
  • [18:56:33] <ds2> PPP over the console serial port? ;)
  • [18:56:36] * ds2 ducks
  • [18:56:46] <jkridner|work> I don't think bennry has this understaning issue if he already has an ext2 partition on his SD card. :)
  • [18:57:04] <jkridner|work> you can download the .ipk to the SD card as well.
  • [18:57:09] <bennry> no, I don't understand what's going on :)
  • [18:57:29] <denix> _apk: have you tried all pal_? variants?
  • [18:57:31] <ds2> if you really want to keep FAT on the SD, you can use umdosfs
  • [18:57:32] <bennry> seriously, my experience with Linux is javac, gcc, and makefile.
  • [18:57:34] <ds2> ;)

  • [18:57:59] <jkridner|work> I've created a ramdisk image of Angstrom with the mtk-utils and mkfs-jffs2 ipk files on the SD card (and in the ramdisk image itself).

  • [19:01:15] <bennry> will tar -czf {output.tgz} {filesystem} work?
  • [19:01:20] <bennry> or am I missing something?
  • [19:02:10] <jkridner|work> to create the tar? you'll likely need to be root, so you can add 'sudo ' to the beginning.
  • [19:02:42] <bennry> yeah
  • [19:02:52] <bennry> just making sure the syntax is correct.

  • [19:15:00] <bennry> could I find these error codes in OMAP docs?

  • [19:15:33] <bennry> did that.
  • [19:15:38] <jkridner|work> the error messages come from Linux, so you wouldn't find the messages in OMAP docs (though you could find what triggers the interrupt)

  • [19:16:41] <bennry> ds2: trying.
  • [19:16:43] <ds2> bennry: top of the tree?
  • [19:17:42] <bennry> the first time I tried booting without SD card, this time I put it back in.
  • [19:17:55] <bennry> but it's configuring linux like it's being set up for the first tiem.
  • [19:17:57] <bennry> hmm.
  • [19:18:07] <bennry> so I don't know which file system it's using, but it's booting.
  • [19:18:09] <ds2> pastebin the error, please.

  • [19:18:21] <bennry> it's gone, sorry.
  • [19:18:25] <bennry> if I get it again I will.

  • [20:10:44] <mru> max resolution is 2048x2048
  • [20:10:50] <mru> the real limit is the pixel clock
  • [20:11:15] <linitrofe> and what's the max pixel clock?
  • [20:11:36] <mru> theoretically 86.5 MHz
  • [20:11:50] <mru> some driver changes are needed to get that
  • [20:12:05] <jkridner|work> mru: is that in the data sheet? I believe the data sheet may limit it to 75MHz.
  • [20:12:28] <mru> I read the trm as saying 173/2
  • [20:12:36] <mru> where do you see 75?
  • [20:12:43] * mru may have missed something
  • [20:13:29] <linitrofe> A practical 75mhz pixel clock will deteriorate the performance of any application running on the beagle?
  • [20:14:03] <davr> no, it just limits the maximum resolution+refresh rate
  • [20:14:21] <davr> apparently 1280x1024 60Hz w/ reduced blanking = 91MHz
  • [20:14:44] <linitrofe> 16bpp?
  • [20:14:57] <davr> color depth doesn't matter
  • [20:16:09] <davr> but 1280x1024 50Hz w/ reduced blanking = only 75MHz, I think some monitors will do 50Hz
  • [20:16:20] <davr> but i believe 60Hz is more standard
  • [20:16:32] <linitrofe> The kernel on the git must be compiled wit 2007q3 toolchain?
  • [20:17:12] <linitrofe> because I'm getting several segfaults when I try to run it
  • [20:17:35] <jkridner|work> 2007q3 builds it as does whatever tool-chain OE builds.
  • [20:17:52] <jkridner|work> 2008q1 will only build it with some patches (I do not know the correct patch set).
  • [20:17:53] <linitrofe> ok
  • [20:18:28] <jkridner|work> I think OE may take the 2007q3 and add some patches for building the kernel and then use another toolchain for apps, but I'm not clear on that.
  • [20:18:30] <linitrofe> What I must change on the kernel to set up the resolution I need? drivers/video/omapxxx something?
  • [20:19:01] <linitrofe> (I'm not using OE, it is that the right way to build the kernel?)

  • [20:22:33] <jkridner|work> thanks vlad_.
  • [20:22:50] <linitrofe> also I don't see OE anywhere when I study the google beagle site and the wiki
  • [20:22:53] <jkridner|work> OE makes me lazy, and I'm very lazy. :)
  • [20:23:04] <jkridner|work> Angstrom
  • [20:23:23] <jkridner|work> OE is the build methodology and database...
  • [20:23:26] <jkridner|work> Angstrom is the distro.
  • [20:23:41] <jkridner|work> (hope I got that right, but vlad_ is here to correct me :) )
  • [20:24:01] <linitrofe> I now, but as I don't see it on the documentation I just download the toolchain and start to build kernels using the wiki/google info
  • [20:24:09] <linitrofe> *know
  • [20:24:39] <linitrofe> It work until now :(
  • [20:24:59] * dcordes (n=dcordes@unaffiliated/dcordes) has joined #beagle
  • [20:25:22] <bennry> jkridner|work: yeah, the ultimate goal is sub 1 second. There is no way I can do that the way u-boot or the angstrom distro is right now, but I need gstreamer because I'm thinking of using Clutter with OpenGL and the gstreamer wrapper for my UI.
  • [20:25:40] <bennry> jkridner|work: so, I'll write something up quickly and share it on the email list.
  • [20:26:37] * geraint (n=gnorth@tu008.demon.co.uk) has joined #beagle
  • [20:27:18] <koen> jkridner|work: OE uses a patched 2007q3 (for -Os) for the kernel and a patched gcc 4.3.1 (neon bug) for the rest
  • [20:28:28] <jkridner|work> ah, so I was right! (doesn't happen too often, since I only spend 10 minutes at a time on any given task)
  • [20:28:53] <koen> I want to move too gcc 4.3.2 for userspace soon
  • [20:29:01] <koen> gcc 4.3.2 doesn't need neon patches :)
  • [20:29:19] <denix> yep, I just double-checked, -Os is patched
  • [20:30:16] <denix> vlad_: maybe you're referring to stable branch?

  • [20:30:49] <vlad_> denix: ah, I meant 2007q3-53 direct from codesourcery
  • [20:30:59] <koen> vlad_: how do I build fennec? is it seperate source tree or just a different mozconfig?
  • [20:31:32] <vlad_> koen: you need to build xulrunner (from mozilla-central) and fennec from http://hg.mozilla.org/index.cgi/mobile-browser/

  • [20:37:53] <koen> you'll know in a few days when they finish their pow-wow
  • [20:38:13] <mru> robclark: neat
  • [20:38:15] <jkridner|work> I have a tight time-line for one specific opening.
  • [20:38:50] <robclark> (well, this is just manually patching up the asm... so still a lot of work to actually make it usable. But the theory is good, so I'm happy)
  • [20:45:23] <linitrofe> jkridner|work: the link you send me about DSS and resolution change has an answer of you suggesting applying three patches
  • [20:45:51] <jkridner|work> the patches give you an idea how to adjust resolutions.
  • [20:46:09] <linitrofe> I don't understand the first one, it said beagle gain "DVI-D" support... That's implemented already over the angstrom demo, right?
  • [20:46:18] <jkridner|work> real understanding of how to set the PLL options gets quite a bit deeper.
  • [20:46:47] <koen> vlad_: I have a skeleton for fennec, will try to work on it tonight. I do need to poke robert about the hg fetcher first :)
  • [20:46:50] <jkridner|work> the first link I gave was to the patch putting the DVI-D support into the git tree. that patch is already in the angstrom demo, yes.
  • [20:47:01] <linitrofe> ok!
  • [20:47:08] <vlad_> koen: k, let me know if you have any problems
  • [20:47:23] <koen> vlad_: any news on the 16bpp problem?
  • [20:47:25] <vlad_> koen: we need to hurry up and fix the stupid issues so that I can stop being embarrased at the state of firefox/fennec in OE :)
  • [20:47:33] <jkridner|work> it helps to see the patch because it gives an idea where the DVI-D support plugs into the kernel.
  • [20:47:37] <vlad_> not yet
  • [20:48:18] <koen> jkridner|work: the dvi patch should be in l-o git as well

  • [20:51:00] <jkridner|work> [3] is mru's bootarg selection patch.
  • [20:51:18] <jkridner|work> I thought the 3 made a good summary for what is needed to program various resolutions/modes on Beagle.
  • [20:51:26] <jkridner|work> bit missing item is how to use the DSI PLL.
  • [20:51:35] <jkridner|work> (if I even said that right)
  • [20:51:37] * mru is planning to integrate 2 and 3
  • [20:52:01] <sakoman_> mru: are you planning to submit upstream?
  • [20:52:19] <mru> when the time is right
  • [20:52:26] <sakoman_> ETA?
  • [20:52:31] <mru> unknown
  • [20:52:32] <koen> it would be nice to have vesa + tv confgigs and mbootarg
  • [20:52:37] * mru doesn't do ETAs
  • [20:52:47] * koen stabs laggy connections
  • [20:52:51] <jkridner|work> would "magic parameters" in bootargs make things more flexible until we have full EDID support?
  • [20:53:08] <sakoman_> OK, well the first part might get submitted with my overo submission
  • [20:53:17] <mru> edid would be nice
  • [20:53:20] <sakoman_> but I will make it overo specific
  • [20:53:24] <mru> but that's a separate thing
  • [20:54:01] <jkridner|work> agreed; configurable is one thing, reading EDID and determining the configuration is another.
  • [20:55:27] <koen> edid parsing is present in the kernel
  • [20:55:37] <koen> but it needs some serious recoding of omapfb
  • [20:56:03] <mru> edid retrieval on omap is missing afaik
  • [20:56:34] <prpplague> jkridner|work: did you get your flyswatter adapters?
  • [20:56:59] <mru> and even with edid handling, there should be an option for manual override
  • [20:57:45] <jkridner|work> prpplague: yes.
  • [20:58:13] <prpplague> jkridner|work: i've been totally swampped and haven't had time to pick mine up
  • [20:58:18] <prpplague> jkridner|work: how do they look?
  • [20:58:22] <prpplague> and/or work
  • [20:59:58] <koen> mru: there's a generic edid retrieval method in the kernel
  • [21:00:05] <koen> mru: just pass it your i2c bus
  • [21:00:14] <jkridner|work> look nice. haven't tried to bring them up.
  • [21:00:28] * jkridner|work feels guilty and breaks shrink-wrap.
  • [21:00:30] <mru> koen: good, then getting the edid should be easy
  • [21:01:33] * koen ordered a case for his beagle

  • [21:07:44] <robclark> nice
  • [21:08:02] <koen> mine ships tuesday, so I'll hold off giving wrong advice till I receive it :)
  • [21:09:22] <koen> jkridner|work: edid can be done with the fb_ddc driver
  • [21:09:38] <koen> jkridner|work: maybe within 10 minutes ;)

  • [21:15:05] <jkridner|work> you still have to write the routine that converts those sanely into the modes that you want.
  • [21:15:22] <jkridner|work> reading the EDID is the easy part.
  • [21:15:58] <koen> if it's so easy, you should have no trouble writing a patch for it ;)
  • [21:16:00] <NishanthMenon> http://www.specialcomp.com/beagleboard/index.htm could do with a 2$ toggle switch :D
  • [21:16:06] <jkridner|work> :)
  • [21:16:44] <koen> edid gives you native res + max freq, right?
  • [21:17:19] <jkridner|work> it also gives a list of supported settings.
  • [21:17:32] <jkridner|work> so, it isn't necessarily an open range.

  • [21:18:46] <mru> the detailed list of modes should be easy to use directly
  • [21:19:07] <mru> it's mostly a case of plugging the values directly into dispc registers
  • [21:19:31] <mru> conjuring up a good mode based on ranges is more of an open problem
  • [21:22:49] <NishanthMenon> koen, http://www.stellae.fr/wiki/_media/efika_data:e-edid_implementation_guide_vesa.pdf?id=electronics%3Aefika_en&cache=cache might be interesting

  • [21:29:16] <torus> hi there!
  • [21:29:23] <bennry> Also I'll call out where I got all of the information from.
  • [21:29:57] <linitrofe> I think I didn't set well the pixclock :s omap24xxfb: display mode 1280x1024x16 hsync 12kHz vsync 15Hz

  • [21:31:25] <torus> I'm trying to boot my bb for the first time, and I wonder if I can power the board via usb. It seems to work (e.g. I get the test-tone and the LEDS light up), but I don't see anything on the UART. Shouldn't I see something even if I boot the image w/o anything on the sd-cart?
  • [21:31:55] <jkridner|work> torus: you probably have the wrong serial cable/terminal setup.
  • [21:31:57] <mru> torus: yes, you can power with usb
  • [21:32:22] <torus> allright. and about the uart - the boot-loader trys to output something, right?
  • [21:32:28] <mru> yes
  • [21:32:35] <torus> hmkay.. thanks.
  • [21:32:41] <mru> how are you connecting to the board?
  • [21:32:48] <torus> hehe..
  • [21:33:16] <torus> usb -> usb2serial converter -> nullmodem-cable -> D9 to IDC10 connector.
  • [21:33:54] <mru> the last part there is the one that might go wrong
  • [21:33:54] <torus> I think it's something with the usb2serial converter.. I've never tested it.
  • [21:34:00] <mru> how is that cable wired?
  • [21:34:02] <jkridner|work> have you seen serial data across your usb2serial converter (as it is now configured) with some other device?
  • [21:34:28] <jkridner|work> I've seen that a lot of usb2serial converters are difficult to work with various terminal programs.
  • [21:34:33] <torus> mru. don't know. I took an old one from my hardware-junkbox.. I'll check the pinout.. thanks for the hint.
  • [21:34:45] <mru> torus: there are two common pinouts
  • [21:35:18] <torus> jkridner. good idea... now how do I check if the comport is working without a com-device? :-)
  • [21:35:42] <torus> or... wait.. I still have an old trackball-mouse somewhere...
  • [21:35:48] <jkridner|work> you can short RX and TX.
  • [21:36:11] <jkridner|work> (make sure that you get nothing when they are not shorted and that you get echos when they are shorted)
  • [21:36:19] <torus> jkridner, really? will this echo back what I send?
  • [21:36:31] <jkridner|work> (otherwise, it could be terminal loop-back)
  • [21:36:34] <jkridner|work> yes.
  • [21:36:46] <torus> cool. thanks. great one. didn't knew that.
  • [21:37:16] <torus> thanks a lot, folks..
  • [21:37:17] <jkridner|work> just make sure you short the right pins!

  • [21:48:19] <stevieJ> hi guys, I'm having serial issues with my beagle too - I see the bootup text, but no console input. I've been doing some signal tracing with a probe and U9 1.8<>3.3 level converter seems to be the problem
  • [21:49:01] <stevieJ> tx line works fine from rs232 back to the omap chip, but the rx line doesn't come out the other side of u9
  • [21:49:03] <mru> stevieJ: are you sure your cables are good and your software is configured properly?
  • [21:49:09] <stevieJ> yup
  • [21:49:16] <stevieJ> all loopbacks work ok
  • [21:49:28] <mru> there have apparently been a few defective boards
  • [21:49:37] <stevieJ> been reading the irclogs, so checked pretty much everything
  • [21:49:39] <mru> something with rs232 rx not working...
  • [21:50:12] <stevieJ> guess I may have one. shame as it's been in UK customs for the last two weeks
  • [21:50:55] <stevieJ> loathe to send it back. just wondering if anyone else has had the same hardware issue?
  • [21:53:53] <denix> are you sure it wasn't UK customs who broke it? :)
  • [21:53:57] <torus> got it... my rs232 to IDC cable has the wrong pinout...
  • [21:54:16] <jkridner|work> yes, there have been about a half-dozen returns out of the 600 boards or so that have gone out already due to U9 issues. :(
  • [21:54:29] <torus> and btw - I had issues with (german) customs as well. It wasn't easy to get the board.
  • [21:54:41] <jkridner|work> (don't hold me to the numbers--that is just my rough understanding)
  • [21:54:44] <stevieJ> well the package had been opened by customs
  • [21:54:48] <prpplague> torus: what kind of issues did you have?
  • [21:55:04] <jkridner|work> the boards have gone through a burn-in process to try to capture the U9 failures, but some have still escaped.
  • [21:55:51] <torus> prpplague, first off it wasn't easy to convince digi-key that I'm not a terrorist and that shipping the bb to europe is fine... and then the board was over a week in customs and had been opened three times.
  • [21:56:01] <jkridner|work> most people think they have this problem, but actually have the wrong IDC10-to-DB9 adapter or don't use a null modem cable or have a USB-to-serial converter that doesn't work with their terminal program.
  • [21:56:10] <stevieJ> ok, well u9 seems to be still pulling up to 1.8v on the rx line okay so I was going to try injecting the rs232 rx through an npn transistor
  • [21:56:25] <prpplague> torus: but no specific info from customs as to what caused the concern?
  • [21:57:06] <linitrofe> i have that issue
  • [21:57:18] <linitrofe> I thought it was a kernel problem
  • [21:57:38] <linitrofe> but I also check the voltage level on Rx and have strange meassure
  • [21:58:38] <linitrofe> somketimes it work, sometimes not
  • [21:58:52] <stevieJ> yup, I've tried all combinations of hardware. but analyser says no rx signal going to omap at TP22, yet it's coming thru the rs232 chip pin 9 fine
  • [21:58:59] <linitrofe> but as I don't have network connection with the board I prefer to wait

  • [22:12:38] <jkridner|work> stevieJ: I suggest you explain your experience with customs in the RMA request. I don't know that much could be done to send out a replacement ahead of getting the return though. :(
  • [22:13:30] <stevieJ> hehe yeah, I certainly wouldn't like being billed $60 twice in a row ;)

  • [22:15:47] <stevieJ> well it might look like I can hack it, as I can loopback the omap tx into its rx and the boot loader chokes on its own print trying to interpret it as commands, so at least the u9 package isn't shorting rx line to 1.8v
  • [22:16:48] <stevieJ> not sure I want to do that just yet, but testing theories.
  • [22:27:53] <torus> the beagle talks to me :-) Problem solved..
  • [22:29:32] <jkridner|work> this was a good example of two different problems that could have looked the same.
  • [22:30:04] <jkridner|work> great torus! looking forward to some great demos/apps/etc.
  • [22:31:29] <torus> :-)
  • [22:31:38] <torus> yea.. I'll do something..
  • [22:32:19] <torus> now I have to figure out how to get a bash on the board.
  • [22:32:58] <jkridner|work> you using one of the distros?
  • [22:33:47] <torus> can you recommend one?
  • [22:34:04] <torus> I don't need any graphics at the moment, just bash and the usual tools.
  • [22:34:58] * Olipro (n=Olipro@uncyclopedia/Olipro) has joined #beagle
  • [22:42:55] <jkridner|work> for something really minimal, you can just use the stuff on code.google.com/p/beagleboard to get started...
  • [22:43:22] <jkridner|work> but, I'd probably want to get started with http://www.angstrom-distribution.org/beagleboard-demo-image-available
  • [22:44:13] <jkridner|work> for something OE based but more minimal, you can use one of the console-image tar.gz files from http://amethyst.openembedded.net/~koen/index.php?path=beagleboard/
  • [22:44:36] <jkridner|work> such as http://amethyst.openembedded.net/~koen/beagleboard/Angstrom-console-image-glibc-ipk-2008.1-test-20080721-beagleboard.rootfs.tar.bz2
  • [22:44:50] <jkridner|work> (you can use the kernel image from the demo)
  • [22:45:07] <torus> nice thanks.
  • [22:45:18] <mru> "the beagle talks to me"; take that out of context...
  • [22:45:45] <jkridner|work> I did some builds of console-image at http://www.beagleboard.org/~angstrom/tmp/deploy/glibc/images/beagleboard/, but I don't know how long I will keep that link live.
  • [22:46:26] <jkridner|work> I know console-image uses busybox.
  • [22:46:39] <jkridner|work> jason-console-image might use bash, but I forget. (checking)
  • [22:47:14] <torus> btw - how do I tell the kernel which file-system to mount as rootfs? I've used the precompiled binaries from http://code.google.com/p/beagleboard/wiki/BeagleSourceCode
  • [22:47:17] <jkridner|work> nope, jason-console-image still uses busybox.
  • [22:48:06] <jkridner|work> I just added mtd-utils and mkfs-jffs2.
  • [22:48:23] <jkridner|work> I need to find the easy way to make a ramdisk using OE.
  • [22:49:04] <jkridner|work> I still haven't found all of "magic" in how the images get created (don't see 'tar' anywhere in image.bbclass).
  • [22:49:25] * JoeyBorn (n=jborn@dsl017-022-252.chi1.dsl.speakeasy.net) Quit (Read error: 110 (Connection timed out))
  • [22:51:26] <jkridner|work> you tell the kernel which device/partition has the file system you want via the bootargs 'root=' parameter.
  • [22:52:45] <jkridner|work> you also need to pay attention to the file system format (ext3/jffs2/ramdisk/etc).
  • [22:53:57] <jkridner|work> ramdisk images are often ext2 formatted (per rd-ext2.bin on http://code.google.com/p/beagleboard/wiki/BootingBeagleBoard), but require being loaded from RAM via the 'initrd' parameter.
  • [22:54:45] <denix> jkridner: you know about IMAGE_FSTYPES, right?

  • [22:57:28] <torus> now i got it..
  • [22:59:52] <jkridner|work> denix: where are the bb/bbclass files that make use of IMAGE_FSTYPES?

  • [23:03:55] <jkridner|work> easy enough to do manually, but it seems like the power of OE is that I can manage the build process.
  • [23:04:19] * geraint (n=gnorth@tu008.demon.co.uk) Quit ()
  • [23:05:09] <calculus> I normally have the kernel build the initramfs by using the option to pass it a file with all the files I would like in the image

  • [23:06:09] <denix> jkridner: oh, I see. guess it's out of scope of console/minimal image recipe...
  • [23:06:17] <denix> calculus: can you do it with OE?
  • [23:07:02] <calculus> probably, just change the defconfig
  • [23:07:15] <calculus> CONFIG_INITRAMFS_SOURCE
  • [23:08:16] <calculus> it is a text file with a few columns where each line represents a file in the image
  • [23:08:54] <calculus> dir /dev 0755 0 0
  • [23:08:55] <calculus> nod /dev/console 0600 0 0 c 5 1
  • [23:08:55] <calculus> nod /dev/tty1 0600 0 0 c 4 1
  • [23:08:57] <jkridner|work> that's an option, though I will need to create 2 kernels.
  • [23:10:43] <jkridner|work> does provide the possibility of a single file distribution that can be used directly on the board (flash or SD).

  • [23:16:07] * denix is now away
  • [23:16:29] <jkridner|work> yeah, I've actually done it with the old rd-ext2.bin file system, so I know it doesn't require the hacking of that text file.
  • [23:18:16] * calculus has been doing it the hard way with a text file
  • [23:18:51] <calculus> missing out on dynamically linked libs was the hard part

  • [23:23:38] <sakoman_> this one was even closer than the last
  • [23:23:38] <jkridner|work> sakoman_: does it ever end for you?
  • [23:24:00] <sakoman_> feels like the fire season that won't end!
  • [23:24:05] * geraint (n=gnorth@tu008.demon.co.uk) Quit ()
  • [23:24:38] <sakoman_> cool to watch the water bombers *really* close up
  • [23:25:10] <sakoman_> we could see which side the pilots parted their hair ;-)
  • [23:25:57] <jkridner|work> No thanks. Though, I probably would trade locations on any other day.
  • [23:27:33] <sakoman_> Gordon didn't like me being distracted from Overo work, the big push has begun ;-)
  • [23:28:08] <jkridner|work> gimme, gimme.
  • [23:29:32] <sakoman_> It is turning out really well
  • [23:29:44] <sakoman_> Cool product
  • [23:30:42] <stevieJ> ok, happy to announce I fixed my beagle board :)
  • [23:30:49] <jkridner|work> have you looked at JTAG debug options?
  • [23:31:02] <jkridner|work> whoa! great stevieJ!
  • [23:31:05] <jkridner|work> how did you do it?
  • [23:31:10] <jkridner|work> heat?
  • [23:31:10] <stevieJ> made a simple smt rs232 level shifter and soldered it between connector and omap rx
  • [23:31:16] <jkridner|work> ah!
  • [23:31:22] <sakoman_> jkridner|work: no haven't looked at jtag at all
  • [23:31:35] <sakoman_> hope I don't need to!
  • [23:31:54] <jkridner|work> some of the Overo customers might like it.
  • [23:32:01] <stevieJ> seems okay on voltage levels, good clean signal to cpu so I'm happy with that
  • [23:32:13] <jkridner|work> Perhaps they can all afford Lauterbachs.
  • [23:32:46] <jkridner|work> you are talented stevieJ. Glad to see you playing with a Beagle!
  • [23:32:56] <sakoman_> I don't think most gumstix customers are jtag users
  • [23:33:07] * mru uses lauterbach a lot at work
  • [23:33:07] <stevieJ> heh, thanks to all at TI for letting us ;)
  • [23:33:23] <sakoman_> the jtag option for the previous generation had extremely low sales from what I understand
  • [23:33:25] <stevieJ> have lots planned now

  • [23:36:09] <jkridner|work> I guess that is no longer necessary as it is hard to brick the OMAP3 systems with SD/serial/usb boot.
  • [23:36:25] * jkridner|work must head home.
