**** BEGIN LOGGING AT Mon Jul 19 02:59:56 2010 Jul 19 09:07:45 mornig Jul 19 09:36:14 * cwillu_at_work dances with hrw Jul 19 09:38:11 que? Jul 19 09:38:55 my beagles are no longer leaking memory like little 2kb sieves Jul 19 12:26:19 hi to everybody... Jul 19 12:26:47 I've the same problem... segmentation fault on line 282 in rootstock Jul 19 12:27:15 now I'm using a physical ubuntu Lucid installation Jul 19 12:27:19 any idea? Jul 19 12:30:33 http://www.mail-archive.com/ubuntu-bugs@lists.ubuntu.com/msg2382346.html Jul 19 12:30:59 furibondox: known issue Jul 19 12:31:09 furibondox: what rootstock version are you using? Jul 19 12:31:30 bug 604872 Jul 19 12:31:32 Launchpad bug 604872 in qemu-kvm (Ubuntu) (and 1 other project) "qemu-system-arm segfaults emulating versatile machine after running debootstrap --second-stage inside vm (affects: 1) (heat: 8)" [Medium,Triaged] https://launchpad.net/bugs/604872 Jul 19 12:31:41 depends on what you're installing Jul 19 12:31:51 sometimes it just get stuck and sometimes you'll get the segfault Jul 19 12:31:53 rsalveti: the latest from ubuntu repository Jul 19 12:32:17 furibondox: you can try upstream version, I'm still fixing other bugs before releasing a new version Jul 19 12:32:37 from svn? Jul 19 12:32:38 but you're still going to have the seg fault, the only difference is that it's going to try qemu more than once Jul 19 12:32:43 furibondox: bzr Jul 19 12:32:52 ok Jul 19 12:32:56 I will try Jul 19 12:33:08 bzr branch lp:project-rootstock Jul 19 12:34:43 I'm installing bzr Jul 19 12:34:46 rootstock reworked to use a chroot works great :) Jul 19 12:35:21 cwillu_at_work: using chroot instead of qemu???? Jul 19 12:35:30 furibondox, chroot with qemu-static Jul 19 12:35:32 chroot with qemu Jul 19 12:35:38 ah ok Jul 19 12:35:53 it actually works spectacularly well :p Jul 19 12:36:01 furibondox: the problem is that the additional packages are installed with apt-get Jul 19 12:36:02 as you can make use of as many cores as you have available, etc Jul 19 12:36:04 with a full vm Jul 19 12:36:37 rsalveti, I reworked it to not use the vm at all beyond the chroot itself Jul 19 12:36:47 so, if you're still getting lots of segfault, try installing ubuntu-minimal and then installs the rest at your board Jul 19 12:37:15 cwillu: yeah, with root this is the best way Jul 19 12:37:23 still need to take a better look at that Jul 19 12:37:29 cwillu_at_work: gota a patch? Jul 19 12:37:42 not really; I've really had my way with the script Jul 19 12:37:48 actually, I guess alot of it would be patchable Jul 19 12:37:57 rsalveti: if I try to install ubuntu-minimal and then I create a script to install all the other packages I need and I call it with --script it should work? Jul 19 12:38:02 yeah, don't worry, will take a better look at it later Jul 19 12:38:14 it's pretty straightforward though Jul 19 12:38:18 yep Jul 19 12:38:30 it'll need some tweaks after the rootless changes.. ;) Jul 19 12:38:50 rcn-ee: yep, but still somehow an easy change Jul 19 12:39:03 furibondox: nops, because the script runs inside the vm Jul 19 12:39:30 what you can do is to mount the filesystem, copy qemu static on it and chroot Jul 19 12:39:39 then you are free to work on whatever you want Jul 19 12:39:48 ok Jul 19 12:39:52 https://wiki.ubuntu.com/ARM/RootfsFromScratch Jul 19 12:40:00 furibondox: see sing qemu user mode emulation (with chroot) Jul 19 12:40:05 *using Jul 19 12:41:15 OK, however now I try with the latest bzr release Jul 19 13:05:16 ogra: Can you send me the line to make boot.scr please? Jul 19 13:05:24 mkimage *** Jul 19 13:05:44 mkimage -A arm -T script -C none -n "Ubuntu boot script" -d Jul 19 13:18:35 ogra: how many bytes does mkimage adds to initrd? Jul 19 13:18:47 hrw, i think 64 ... one sec Jul 19 13:19:25 hrw, 72 :) https://wiki.ubuntu.com/ARM/BeagleEditBootscr Jul 19 13:19:33 * ogra knew he wrote that up somewhere Jul 19 13:19:42 thx Jul 19 13:21:11 ogra: ok, why does this not work?: dd if=/mnt/uInitrd skip=1 bs=72 | gunzip -c | cpio -t Jul 19 13:21:58 ogra: Cheers Jul 19 13:23:41 ogra: a vanilla mkimage only adds 64, no? Jul 19 13:26:49 slangasek, probably because -T ramdisk adds different stuff Jul 19 13:27:00 ukleinek, might be, i think it varies with the comment (-n option) Jul 19 13:27:18 ogra: well, so how do I unpack it? :) Jul 19 13:27:23 so the 72 might only be true if the comment is "Ubuntu boot script" Jul 19 13:27:48 ogra: IIRC, no Jul 19 13:27:49 slangasek, i never unpacked a uInitrd Jul 19 13:28:03 the comment is "Ubuntu Initrd" Jul 19 13:28:05 ukleinek, funny, then i wonder why 72 works Jul 19 13:28:48 slangasek, you flipped bs and skip options ?

Jul 19 14:17:36 cooloney: if you're at prague we cat probably give you one beagleboard so you can reproduce it Jul 19 14:18:00 cooloney: same issue with latest lucid kernel, 2.6.33-502-omap Jul 19 14:18:50 rsalveti: awesome, i am in kernel room and love to test Jul 19 14:19:46 robclark, https://code.edge.launchpad.net/~ogra/jasper-initramfs/trunk has the code in jasper_setup Jul 19 14:19:59 * robclark looks Jul 19 14:20:12 http://bazaar.launchpad.net/~ogra/jasper-initramfs/trunk/files rather Jul 19 14:21:03 cooloney: can you get by the arm room later? just because there are lots of cables and devices to be moving around Jul 19 14:21:19 GrueMaster, http://rcn-ee.net/deb/tools/UBOOT/u-boot-beagleboard-2010.03+r52+gitrca6e1c136ddb720c3bb2cc043b99f7f06bc46c55-r52.bin Jul 19 14:21:28 rsalveti: no problem. i'd love to Jul 19 14:21:56 cooloney: don't need to hurry, will be here for the whole week :-) Jul 19 14:21:57 .oO(why did i just read "i love you" above ... ) Jul 19 15:18:19 cooloney: now it doesn't work at all :D Jul 19 15:18:34 was finally able to test it Jul 19 16:02:35 cooloney: mkimage -A arm -T script -C none -n "Ubuntu boot script" -d Jul 19 16:04:30 Guest78932: sudo dd if=/media/4C43-C886/boot.scr of=boot.script skip=64 bs=1 Jul 19 16:04:40 Guest78932: is this right? ^^ Jul 19 16:05:12 Yep Jul 19 16:12:53 bye Jul 19 18:27:42 Hello Jul 19 18:28:12 I am looking to install Ubuntu on a Archos 5 IT, any pointers? Jul 19 19:09:19 hi folks! Jul 19 19:09:37 i have a little question Jul 19 19:10:07 i'mm looking for a small system to begin with ubuntu/arm development Jul 19 19:10:26 i would like to have some advice Jul 19 19:11:42 which one you think is most suitable to begin?? Jul 19 19:12:01 beagleboard? or tincantools' hammer? Jul 19 19:12:19 loluengo, beagleboard Jul 19 19:12:26 why? Jul 19 19:12:49 i mean... why pcacjr? Jul 19 19:13:01 any advantage? Jul 19 19:13:06 hmm Jul 19 19:13:18 it's simple to use Jul 19 19:13:45 you could get the beagleboard C4 Jul 19 19:13:58 it's a good hw Jul 19 19:14:07 i think the tincantools' nail kit is also very easy Jul 19 19:14:39 loluengo, well i've only been hacking on beagleboard lately Jul 19 19:15:25 loluengo, http://beagleboard.org is a good start Jul 19 19:15:53 and flyswatter for jtag progamming? Jul 19 19:16:30 maybe :-), depends on you mate Jul 19 19:16:34 heh Jul 19 19:18:01 any other not-so-expensive jtag emulator recommendation? Jul 19 19:19:09 What image do I use to install Ubuntu on an ARM device? Jul 19 19:21:04 i looked at ti.com page and all of the emulator the recommend are VERY expensive! Jul 19 19:23:45 loluengo: it all depends on what you want to do Jul 19 19:24:18 loluengo: for alot of the basic operations of OMAP3 you don't really need a jtag Jul 19 19:25:23 prpplague, what do you mean by basic operations? Jul 19 19:25:55 loluengo: the OMAP3 has internal rom code that supports booting from SD card, uart, USB and nand flash Jul 19 19:26:11 loluengo: so jtag isn't really needed for initial bootloader programming Jul 19 19:26:35 prpplague, programming? debugging? tracing? Jul 19 19:27:26 loluengo: basic programming debugging can be done via uart or other I/O, but if you really need jtag, you can use something like the flyswatter with openocd Jul 19 19:27:53 hmmm Jul 19 19:28:11 that sounds like a great PLUS for beagleboard Jul 19 19:28:28 (over tincantools' hammer) Jul 19 19:29:11 loluengo: beagle and hammer aren't exactly in the same ball park Jul 19 19:29:17 loluengo: they are for different purposes Jul 19 19:35:21 prpplague, why do you say that? Jul 19 19:35:30 i see them similar Jul 19 19:35:42 both are arm-based boards Jul 19 19:35:46 both run linux Jul 19 19:35:55 loluengo: the hammer was designed as a hardware developers platform with limited resources Jul 19 19:36:17 loluengo: the beagle was designed as a software development platform with very little hardware expansion Jul 19 19:36:41 loluengo: they are vastly different target audience Jul 19 19:36:47 s/are/have Jul 19 19:36:56 aaahhh ok Jul 19 19:37:33 if i understood hammer is like a processor module - no peripherals added Jul 19 19:38:16 and beagleboard has plenty of peripherals, intended to develop software Jul 19 19:40:21 exactly Jul 19 19:40:50 loluengo: the hammer is available with some peripherals, but those are mainly for testing and reference for the developer Jul 19 19:43:16 good advice prpplague Jul 19 19:43:42 i think hammer is for me... Jul 19 19:44:19 my work is more hardware oriented than software oriented Jul 19 19:49:30 loluengo: is there something specific you are planning to work on? Jul 19 19:51:33 prpplague, yes... some kind of data logging device Jul 19 19:51:43 loluengo: ahh Jul 19 19:52:44 prpplague, not so interesting, but veeery useful Jul 19 21:10:19 Hello Jul 19 21:10:44 I'm trying to port Ubuntu to an armv6 device, that uses fbdev and am writing an xorg.conf Jul 19 21:10:51 It uses a fbdev device Jul 19 21:11:19 But I'm getting (ee) fbioblank Invalid argument error Jul 19 21:11:23 Any ideas? Jul 19 21:12:23 ogra_cmpc: Did you write rootstock by the way? Jul 20 00:21:40 Ive been at this for several hours. Anyone care to help me install Ubuntu on a ARM device? **** ENDING LOGGING AT Tue Jul 20 02:59:56 2010
