**** BEGIN LOGGING AT Thu Mar 01 02:59:59 2012 Mar 01 08:50:40 GrueMaster: their new kernels *should* be based on the linaro tree (which does branch from ubuntu), whether that is actually true, remains to be seen Mar 01 11:11:11 Is there a list of ARM boards which Ubuntu will run on anywhere? Mar 01 11:12:04 nvm got it Mar 01 11:12:05 https://wiki.ubuntu.com/ARM/DeviceSupport Mar 01 14:13:22 guys where I can grab SD images for panda/armhf? Mar 01 14:16:19 fetching http://cdimage.ubuntu.com/releases/12.04/alpha-2/precise-preinstalled-server-armhf+omap4.img.gz Mar 01 14:42:27 hrw, we're at beta1 :) (will release today) Mar 01 14:42:49 hrw, better zsync the current daily on top of that old alpha2 image Mar 01 14:43:00 ogra_: apt-get dist-upgrade helps Mar 01 14:43:08 ogra_: url? Mar 01 14:44:36 http://cdimage.ubuntu.com/daily-preinstalled Mar 01 16:22:59 I thought the SheevaPlug was arm v6? This says it comes with Ubuntu. http://hardware.slashdot.org/story/12/03/01/0732247/stealthy-pen-test-unit-plugs-directly-into-110-vac-socket-video Mar 01 16:23:39 jaunty perhaps ? Mar 01 16:23:53 2.6.32 kernel Mar 01 16:23:59 and ? Mar 01 16:24:05 Could be Karmic. Mar 01 16:24:13 it wouldnt come with any ubuntu kernel anyway Mar 01 16:24:30 could be jaunty with a 3.0 kernel :P Mar 01 16:24:56 even Mar 01 16:25:35 Karmic was arm v6 and 2.6.32 kernel on marvel. Seeing the patch blob we got for their latest system, it looks like their tree encompasses all. Mar 01 16:26:11 Or they could have just pulled recent packages and respun. Not too terribly difficult. Mar 01 16:27:18 sure, all i'm saying is that the kernel doesnt say a thing about the rootfs Mar 01 16:28:22 apparently you can have it in pink though Mar 01 16:28:30 if you have pink wallplugs Mar 01 16:28:38 Ah, they have an ubuntu-9.04.tar.gz. Jaunty. Mar 01 16:28:41 s/plugs/sockets/ Mar 01 18:05:38 janimo`: Didn't you have ghc building on armhf earlier? Mar 01 18:27:34 hey alls, does anyone know a streamlined way to convert a working pandaboard ubuntu install on SDcard to read-only? unionfs/aufs/similar? Mar 01 18:28:01 mount -o remount,ro / Mar 01 18:28:02 ? Mar 01 18:28:28 pbuckley thanks but i believe i need to be able to write to config dirs e.g. to start X Mar 01 18:28:57 well you should give us a full description of what you want in order for us to give you a useful answer Mar 01 18:29:10 pbuckley fair enough Mar 01 18:30:16 i have a working system that boots to X and launches a non-interactive opengl-es app. i want it to mount the root filesystem read-only so i can simply hit the power off and not risk corrupting the filesystem. the goal is maintenance free reliability in a remote location. Mar 01 18:31:21 ah.. are these devices going to have network access in the remote locations? Mar 01 18:31:24 no Mar 01 18:31:52 well.. you can do that with partitions on the sd card Mar 01 18:32:04 like mount /var tmpfs or something Mar 01 18:32:10 put /home somewhere Mar 01 18:32:22 then do the mount -o ro / Mar 01 18:32:47 ok thanks Mar 01 18:33:23 (youll get a nice little performance boost dropping your locks/run/logs into ram Mar 01 18:33:38 you just need to make sure that you have logrotate or smething to keep the log file sizes limited Mar 01 18:34:00 also turn off swap if can.. if that starts hitting the sd card the user experience will be crap Mar 01 18:34:31 so to be clear: Mar 01 18:35:05 i should add one or more partitions to the sdcard, and point my ubuntu at a different partition for /var .. Mar 01 18:35:16 presumably i can leave home on root since nothing will be written there Mar 01 18:35:43 x writes out some temp files to the users home dir Mar 01 18:35:56 also make sure /tmp ends up being writtable Mar 01 18:36:02 right right ok Mar 01 18:36:12 so /var, /home and /tmp need to be writable Mar 01 18:36:17 yeh Mar 01 18:36:28 ok thanks Mar 01 18:36:33 np Mar 01 18:37:23 pbuckley: Thanks for that. I was distracted with post-beta 1 cleanup. Mar 01 18:37:40 btw: PandaES now has audio support in the Beta 1 image. Mar 01 18:37:58 \o/ Mar 01 18:38:43 so two new weird things Mar 01 18:39:16 i was doing a network stress test on my dev board.. after about 20 hours it started dropping consistently about 9% of the packets that went away after a reboot Mar 01 18:39:21 trying to reproduce it now Mar 01 18:39:31 and i just spaced on the other thing :( Mar 01 18:40:20 maybe it was just that my dev board actually made it more then 3 hours Mar 01 18:40:21 heh Mar 01 18:41:20 Interesting. I'll look into an automated network stress test here. Would be good to have. Mar 01 18:41:46 * GrueMaster is always looking for more automated tests. Mar 01 18:42:15 anyone know what time the 12.04 beta comes out exactly? Are arm images being released as well? Mar 01 18:42:28 thats a GrueMaster question Mar 01 18:44:10 ATP: Anny minute now. If you absolutely want it now, go to http://cdimage.ubuntu.com/daily-preinstalled/20120301.1/ for desktop, http://cdimage.ubuntu.com/ubuntu-server/daily-preinstalled/20120228.1/ for server. Mar 01 18:45:27 GrueMaster, you know which is image is best for beagleboard? Mar 01 18:45:32 armhf or omap? Mar 01 18:45:56 They should all be armhf, but omap is the beablebard image. Mar 01 18:46:32 The armel images are just residue that hasn't been scraped out yet. Mar 01 18:46:33 ok so I guess I can wait for the official release of the beta Mar 01 18:46:58 where should I watch for the announcement ? is distrowatch.com fast enough? :P Mar 01 18:47:32 atp, the links I gave you will be the official images. They are being copied to http://cdimage.ubuntu.com/releases/precise/beta-1 now and should be visible shortly. Mar 01 18:47:35 ... if i just go ahead and make ext2 partitions for /var and /home, is there not a risk of corruption? how do i hook unionfs/aufs into this process? is that desirable in my case? Mar 01 18:47:58 Not sure on the release announcement. Maybe just ubuntu.com? Mar 01 18:48:01 GrueMaster, ok thank you I download these then Mar 01 18:50:26 ... and if i just go `mount` it looks like var/run and var/lock are already mounted as tmpfs, tho they are not in fstab . where are these coming from? Mar 01 18:54:29 damian0815: I think those are mounted in upstart. Mar 01 18:54:29 GrueMaster, I touched ghc only briefly a year ago. No armhf poking from me Mar 01 18:54:39 janimo`: Ok. Mar 01 18:55:04 k thx. /me googles upstart . just when you think you know enough about Linux there's always something else.. Mar 01 18:56:48 Yea, progress can be a funny thing. Next thing you know, we'll have cell phone cluster computing. Oh, wait... I already did that. http://gruemaster.blogspot.com/2011/09/i-survived-sort-of.html Mar 01 18:57:05 nice! Mar 01 18:58:36 heh Mar 01 18:59:36 I did that with 6 pandas. Now I have 8. Muahaha! Mar 01 19:03:52 GrueMaster do you have any issues with temperature control? Mar 01 19:05:42 No, my office is nice and cool at 68F (20C). Mar 01 19:06:06 so they're not enclosed i'm guessing.. Mar 01 19:06:37 All my systems are open air. Even my Core2Duo test system. Mar 01 19:07:22 I had a small heat sink on my PandaES, but it hasn't felt warm since 12.04 Alpha 1. Mar 01 19:07:48 No heat sinks on other arm systems. Mar 01 19:09:37 here is what one of my panda towers looks like. http://members.dsl-only.net/~tdavis/Panda-rack.jpg Mar 01 19:19:06 so this guy is trying to achieve a similar thing (read-write sandbox on top of read-only known good base), the second post is a script that is supposed to mount / readonly then make a union with an rw tmpfs using aufs: http://ubuntuforums.org/showthread.php?p=5422268 Mar 01 19:19:27 only thing is it's from 2006. look like it would still work? Mar 01 19:19:48 (i'm running ubuntu 10.10) Mar 01 19:28:38 First, dare I ask why 10.10? Mar 01 19:31:02 heh Mar 01 19:31:20 only way it seems i can do opengl-es at 1920x1080 with working hardware acceleration Mar 01 19:31:31 (3 weeks of pain in that sentence) Mar 01 19:39:18 Hrm. I thought we had support in 11.10 (a little late, but there). Mar 01 19:40:20 i didn't try 11.10 Mar 01 19:40:32 once i got it working.. no more upgradey Mar 01 19:41:26 Ah. Well just understand that 10.10 was an initial release for panda, and it will be going away after April (18 month support). Mar 01 19:49:10 hi all, small question I am asking around Mar 01 19:49:26 trying to install eclipse on linaro omap4 images Mar 01 19:49:33 pandaboard Mar 01 19:49:50 it fails with the following messages Mar 01 19:49:50 http://pastebin.pandaboard.org/index.php/view/95457828 Mar 01 19:51:02 any ideas ? Mar 01 19:51:19 * GrueMaster is checking Mar 01 19:52:59 dipper: Well, it works fine on my ubuntu precise images, but I don't test Linaro. Mar 01 19:53:14 They may have broken dependencies in ppa's or something. Mar 01 19:53:30 is there a workaround ? Mar 01 19:53:37 not through apt-get Mar 01 19:54:08 GrueMaster: where can I get desktop images for pandaboard ? Mar 01 19:54:21 Like I said, I don't know. I did "apt-get update && apt-get install eclipse, and it gave me a ton of packages. Mar 01 19:54:33 i see Mar 01 19:54:44 I was advised linaro for pandaboard Mar 01 19:54:53 I am open to switch to something else Mar 01 19:54:56 if there is anything Mar 01 19:55:34 We are just releasing beta 1 soon. Check http://cdimage.ubuntu.com/releases/12.04/. It should show up soon. Mar 01 20:19:06 ok looks like i have a working ro / Mar 01 20:19:22 thanks for the help everyone Mar 01 20:21:57 hey yall. What is the best sd or mmc-card for a pandaboard? Mar 01 20:37:59 j_ack: Something Class 10 and 4G or better. Mar 01 20:38:22 GrueMaster, thank you Mar 01 22:00:54 I have a question about jasper-initramfs. Anyone familiar with it present? Mar 01 22:01:46 int_ua: What's up? Mar 01 22:02:17 GrueMaster: Why is jasper-initramfs is built only for i386? Mar 01 22:02:42 It is a shell script. It should be arch-all. Mar 01 22:03:16 It never run on my N900, but I don't remember if it boots at all with standard preinstalled image, I'm using a script to configure it Mar 01 22:03:32 huh? Mar 01 22:03:43 GrueMaster: the package is _all Mar 01 22:03:47 It is used in our preinstalled images. Mar 01 22:03:57 GrueMaster: But it's not in the repos Mar 01 22:03:59 yeh i know.. just having trouble parsing what he's saying Mar 01 22:04:28 It's main purpose is to grow the rootfs on the sd card and other first-boot initialization. Mar 01 22:04:38 And it is in the repos. Mar 01 22:04:46 GrueMaster: but it's not present in the recent Precise OMAP3 image, is it? Mar 01 22:05:17 GrueMaster: strange, I can't see it Mar 01 22:05:30 yes, otherwise the image wouldn't boot. Mar 01 22:05:49 It is in the initrd. Once it runs, it rebuilds the initrd and removes itsself. Mar 01 22:06:03 Well, wouldn't boot properly. Mar 01 22:07:20 GrueMaster: I'm puzzled. You mean it will never boot completely. It must boot into initramfs. Or it's not booting? Mar 01 22:08:00 If it doesn't run, the root filesystem won't have enough room to do anything. Mar 01 22:08:16 And it is jasper in the repo. Mar 01 22:08:42 jasper-initramfs is the source repo. Mar 01 22:09:24 GrueMaster: Ok, got it. Another question: what should I do if the image doesn't boot at all? My hardware is Nokia N900. Mar 01 22:09:37 (when it was developed, the creator didn't know about the jasper jpeg libraries). Mar 01 22:10:36 We don't support that system directly. But if you have a kernel and bootloaders, you theoretically can make it work by dropping them in the boot partition. Mar 01 22:11:50 rbelem has experience with this system if he's around. Mar 01 22:12:10 also rsalveti. Mar 01 22:13:17 I think we used to have a wiki page with instructions on how to use ubuntu on n900 at wiki.ubuntu.com Mar 01 22:13:28 but in theory it should work fine Mar 01 22:13:54 just need to grab a valid kernel, and have the rootfs available at an external sd card Mar 01 22:14:24 rsalveti: Same kernel & bootloader as omap? Mar 01 22:14:28 Thanks :) I think I've talked with them on #kubuntu-mobile last year. The problem is that the only kernel that boots is 2.6.35 compiled by apachelogger et al (AFAIK) and it doesn't boot any other kernel. Mar 01 22:14:35 (beagle I should say). Mar 01 22:14:46 for that I don't know, n900 is usually broken upstream Mar 01 22:14:55 I remember the best kernel we had available was from the mer project Mar 01 22:14:57 ah. Mar 01 22:16:59 rsalveti: is it possible to watch kernel log from USB on N900? Mar 01 22:17:36 int_ua: just once you booted it completely, if you want to have the logs guess the best way would have it displayed at the n900 screen Mar 01 22:18:32 and when kernels refuse to boot silently?... Mar 01 22:19:26 then just serial to help you knowing what is happening Mar 01 22:44:11 rsalveti, GrueMaster: How do you think, should I add a link to my script ( https://code.launchpad.net/~xintx-ua/ubuntu-n900/ubuntu-n900-installer ) to wiki? Mar 01 22:49:59 int_ua: https://wiki.ubuntu.com/ARM/OMAP Will this work? Mar 01 22:51:07 (under Community Development) Mar 01 22:52:42 No, I'm talking about https://wiki.ubuntu.com/ARM/n900 Mar 01 22:53:01 it's not about OMAP, it is specifically for N900 Mar 01 22:53:07 Oh. Forgot that still exited. Mar 01 22:54:00 GrueMaster: can you please rephrase, I didn't get it? :) Mar 01 22:54:40 I forgot that wiki page was there. It isn't linked in wiki.ubuntu.com/ARM Mar 01 22:55:46 And the Kubuntu-mobile project is no longer maintained afaik. I think they merged into kubuntu-active. Mar 01 22:56:20 But there is not kubuntu-active for arm, is it? Is it temporary? Mar 01 22:56:30 s/not/no/ Mar 01 22:56:52 It is still in its infancy. This (Beta 1) was the first release and only i386. Mar 01 22:59:02 Not sure if/when images for it will be built on arm. Packages are there. Mar 01 23:04:33 leaving now. Thanks for your help, GrueMaster and rsalveti :) **** ENDING LOGGING AT Fri Mar 02 02:59:58 2012
