| GrueMaster | 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 | 16:22 |
| ogra_ | jaunty perhaps ? | 16:23 |
| GrueMaster | 2.6.32 kernel | 16:23 |
| ogra_ | and ? | 16:23 |
| GrueMaster | Could be Karmic. | 16:24 |
| ogra_ | it wouldnt come with any ubuntu kernel anyway | 16:24 |
| ogra_ | could be jaunty with a 3.0 kernel :P | 16:24 |
| ogra_ | even | 16:24 |
| GrueMaster | 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. | 16:25 |
| GrueMaster | Or they could have just pulled recent packages and respun. Not too terribly difficult. | 16:26 |
| ogra_ | sure, all i'm saying is that the kernel doesnt say a thing about the rootfs | 16:27 |
| ogra_ | apparently you can have it in pink though | 16:28 |
| ogra_ | if you have pink wallplugs | 16:28 |
| GrueMaster | Ah, they have an ubuntu-9.04.tar.gz. Jaunty. | 16:28 |

| GrueMaster | janimo`: Didn't you have ghc building on armhf earlier? | 18:05 |
| damian0815 | hey alls, does anyone know a streamlined way to convert a working pandaboard ubuntu install on SDcard to read-only? unionfs/aufs/similar? | 18:27 |
| pbuckley | mount -o remount,ro / | 18:28 |
| pbuckley | ? | 18:28 |
| damian0815 | pbuckley thanks but i believe i need to be able to write to config dirs e.g. to start X | 18:28 |
| pbuckley | well you should give us a full description of what you want in order for us to give you a useful answer | 18:28 |
| damian0815 | pbuckley fair enough | 18:29 |
| damian0815 | 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. | 18:30 |
| pbuckley | ah.. are these devices going to have network access in the remote locations? | 18:31 |
| damian0815 | no | 18:31 |
| pbuckley | well.. you can do that with partitions on the sd card | 18:31 |
| pbuckley | like mount /var tmpfs or something | 18:32 |
| pbuckley | put /home somewhere | 18:32 |
| pbuckley | then do the mount -o ro / | 18:32 |
| damian0815 | ok thanks | 18:32 |
| pbuckley | (youll get a nice little performance boost dropping your locks/run/logs into ram | 18:33 |
| pbuckley | you just need to make sure that you have logrotate or smething to keep the log file sizes limited | 18:33 |
| === int_ua is now known as TemporaryTest | ||
| pbuckley | also turn off swap if can.. if that starts hitting the sd card the user experience will be crap | 18:34 |
| === TemporaryTest is now known as int_ua | ||
| damian0815 | so to be clear: | 18:34 |
| damian0815 | i should add one or more partitions to the sdcard, and point my ubuntu at a different partition for /var .. | 18:35 |
| damian0815 | presumably i can leave home on root since nothing will be written there | 18:35 |
| pbuckley | x writes out some temp files to the users home dir | 18:35 |
| pbuckley | also make sure /tmp ends up being writtable | 18:35 |
| damian0815 | right right ok | 18:36 |
| damian0815 | so /var, /home and /tmp need to be writable | 18:36 |
| pbuckley | yeh | 18:36 |
| damian0815 | ok thanks | 18:36 |
| pbuckley | np | 18:36 |
| GrueMaster | pbuckley: Thanks for that. I was distracted with post-beta 1 cleanup. | 18:37 |
| GrueMaster | btw: PandaES now has audio support in the Beta 1 image. | 18:37 |
| pbuckley | \o/ | 18:37 |
| pbuckley | so two new weird things | 18:38 |
| pbuckley | 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 | 18:39 |
| pbuckley | trying to reproduce it now | 18:39 |
| pbuckley | and i just spaced on the other thing :( | 18:39 |
| pbuckley | maybe it was just that my dev board actually made it more then 3 hours | 18:40 |
| pbuckley | heh | 18:40 |
| GrueMaster | Interesting. I'll look into an automated network stress test here. Would be good to have. | 18:41 |
| * GrueMaster is always looking for more automated tests. | 18:41 | |
| ATP | anyone know what time the 12.04 beta comes out exactly? Are arm images being released as well? | 18:42 |
| pbuckley | thats a GrueMaster question | 18:42 |
| GrueMaster | 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. | 18:44 |
| ATP | GrueMaster, you know which is image is best for beagleboard? | 18:45 |
| ATP | armhf or omap? | 18:45 |
| GrueMaster | They should all be armhf, but omap is the beablebard image. | 18:45 |
| GrueMaster | The armel images are just residue that hasn't been scraped out yet. | 18:46 |
| ATP | ok so I guess I can wait for the official release of the beta | 18:46 |
| ATP | where should I watch for the announcement ? is distrowatch.com fast enough? :P | 18:46 |
| GrueMaster | 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. | 18:47 |
| damian0815 | ... 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? | 18:47 |
| GrueMaster | Not sure on the release announcement. Maybe just ubuntu.com? | 18:47 |
| ATP | GrueMaster, ok thank you I download these then | 18:48 |
| damian0815 | ... 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? | 18:50 |
| janimo` | GrueMaster, I touched ghc only briefly a year ago. No armhf poking from me | 18:54 |
| GrueMaster | damian0815: I think those are mounted in upstart. | 18:54 |
| GrueMaster | janimo`: Ok. | 18:54 |
| damian0815 | k thx. /me googles upstart . just when you think you know enough about Linux there's always something else.. | 18:55 |
| GrueMaster | 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 | 18:56 |
| pbuckley | nice! | 18:57 |
| damian0815 | heh | 18:58 |
| GrueMaster | I did that with 6 pandas. Now I have 8. Muahaha! | 18:59 |
| damian0815 | GrueMaster do you have any issues with temperature control? | 19:03 |
| GrueMaster | No, my office is nice and cool at 68F (20C). | 19:05 |
| damian0815 | so they're not enclosed i'm guessing.. | 19:06 |
| GrueMaster | All my systems are open air. Even my Core2Duo test system. | 19:06 |
| GrueMaster | I had a small heat sink on my PandaES, but it hasn't felt warm since 12.04 Alpha 1. | 19:07 |
| GrueMaster | No heat sinks on other arm systems. | 19:07 |
| GrueMaster | here is what one of my panda towers looks like. http://members.dsl-only.net/~tdavis/Panda-rack.jpg | 19:09 |
| damian0815 | 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 | 19:19 |
| damian0815 | only thing is it's from 2006. look like it would still work? | 19:19 |
| damian0815 | (i'm running ubuntu 10.10) | 19:19 |
| GrueMaster | First, dare I ask why 10.10? | 19:28 |
| damian0815 | heh | 19:31 |
| damian0815 | only way it seems i can do opengl-es at 1920x1080 with working hardware acceleration | 19:31 |
| damian0815 | (3 weeks of pain in that sentence) | 19:31 |
| GrueMaster | Hrm. I thought we had support in 11.10 (a little late, but there). | 19:39 |
| damian0815 | i didn't try 11.10 | 19:40 |
| damian0815 | once i got it working.. no more upgradey | 19:40 |
| GrueMaster | Ah. Well just understand that 10.10 was an initial release for panda, and it will be going away after April (18 month support). | 19:41 |
| dipper | hi all, small question I am asking around | 19:49 |
| dipper | trying to install eclipse on linaro omap4 images | 19:49 |
| dipper | pandaboard | 19:49 |
| dipper | it fails with the following messages | 19:49 |
| dipper | http://pastebin.pandaboard.org/index.php/view/95457828 | 19:49 |
| dipper | any ideas ? | 19:51 |
| * GrueMaster is checking | 19:51 | |
| GrueMaster | dipper: Well, it works fine on my ubuntu precise images, but I don't test Linaro. | 19:52 |
| GrueMaster | They may have broken dependencies in ppa's or something. | 19:53 |
| dipper | is there a workaround ? | 19:53 |
| dipper | not through apt-get | 19:53 |
| dipper | GrueMaster: where can I get desktop images for pandaboard ? | 19:54 |
| GrueMaster | Like I said, I don't know. I did "apt-get update && apt-get install eclipse, and it gave me a ton of packages. | 19:54 |
| dipper | i see | 19:54 |
| dipper | I was advised linaro for pandaboard | 19:54 |
| dipper | I am open to switch to something else | 19:54 |
| dipper | if there is anything | 19:54 |
| GrueMaster | We are just releasing beta 1 soon. Check http://cdimage.ubuntu.com/releases/12.04/. It should show up soon. | 19:55 |
| damian0815 | ok looks like i have a working ro / | 20:19 |
| damian0815 | thanks for the help everyone | 20:19 |
| j_ack | hey yall. What is the best sd or mmc-card for a pandaboard? | 20:21 |
| GrueMaster | j_ack: Something Class 10 and 4G or better. | 20:37 |
| j_ack | GrueMaster, thank you | 20:38 |

| int_ua | I have a question about jasper-initramfs. Anyone familiar with it present? | 22:00 |
| GrueMaster | int_ua: What's up? | 22:01 |
| int_ua | GrueMaster: Why is jasper-initramfs is built only for i386? | 22:02 |
| GrueMaster | It is a shell script. It should be arch-all. | 22:02 |
| int_ua | 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 | 22:03 |
| pbuckley | huh? | 22:03 |
| int_ua | GrueMaster: the package is _all | 22:03 |
| GrueMaster | It is used in our preinstalled images. | 22:03 |
| int_ua | GrueMaster: But it's not in the repos | 22:03 |
| pbuckley | yeh i know.. just having trouble parsing what he's saying | 22:03 |
| GrueMaster | It's main purpose is to grow the rootfs on the sd card and other first-boot initialization. | 22:04 |
| GrueMaster | And it is in the repos. | 22:04 |
| int_ua | GrueMaster: but it's not present in the recent Precise OMAP3 image, is it? | 22:04 |
| int_ua | GrueMaster: strange, I can't see it | 22:05 |
| GrueMaster | yes, otherwise the image wouldn't boot. | 22:05 |
| GrueMaster | It is in the initrd. Once it runs, it rebuilds the initrd and removes itsself. | 22:05 |
| GrueMaster | Well, wouldn't boot properly. | 22:06 |
| int_ua | GrueMaster: I'm puzzled. You mean it will never boot completely. It must boot into initramfs. Or it's not booting? | 22:07 |
| GrueMaster | If it doesn't run, the root filesystem won't have enough room to do anything. | 22:08 |
| GrueMaster | And it is jasper in the repo. | 22:08 |
| GrueMaster | jasper-initramfs is the source repo. | 22:08 |
| int_ua | GrueMaster: Ok, got it. Another question: what should I do if the image doesn't boot at all? My hardware is Nokia N900. | 22:09 |
| GrueMaster | (when it was developed, the creator didn't know about the jasper jpeg libraries). | 22:09 |
| GrueMaster | 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. | 22:10 |
| GrueMaster | rbelem has experience with this system if he's around. | 22:11 |
| GrueMaster | also rsalveti. | 22:12 |
| rsalveti | I think we used to have a wiki page with instructions on how to use ubuntu on n900 at wiki.ubuntu.com | 22:13 |
| rsalveti | but in theory it should work fine | 22:13 |
| rsalveti | just need to grab a valid kernel, and have the rootfs available at an external sd card | 22:13 |
| GrueMaster | rsalveti: Same kernel & bootloader as omap? | 22:14 |
| int_ua | 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. | 22:14 |
| GrueMaster | (beagle I should say). | 22:14 |
| rsalveti | for that I don't know, n900 is usually broken upstream | 22:14 |
| rsalveti | I remember the best kernel we had available was from the mer project | 22:14 |
| GrueMaster | ah. | 22:14 |
| int_ua | rsalveti: is it possible to watch kernel log from USB on N900? | 22:16 |
| rsalveti | 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 | 22:17 |
| int_ua | and when kernels refuse to boot silently?... | 22:18 |
| rsalveti | then just serial to help you knowing what is happening | 22:19 |
| int_ua | 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? | 22:44 |
| GrueMaster | int_ua: https://wiki.ubuntu.com/ARM/OMAP Will this work? | 22:49 |
| GrueMaster | (under Community Development) | 22:51 |
| int_ua | No, I'm talking about https://wiki.ubuntu.com/ARM/n900 | 22:52 |
| int_ua | it's not about OMAP, it is specifically for N900 | 22:53 |
| GrueMaster | Oh. Forgot that still exited. | 22:53 |
| int_ua | GrueMaster: can you please rephrase, I didn't get it? :) | 22:54 |
| GrueMaster | I forgot that wiki page was there. It isn't linked in wiki.ubuntu.com/ARM | 22:54 |
| GrueMaster | And the Kubuntu-mobile project is no longer maintained afaik. I think they merged into kubuntu-active. | 22:55 |
| int_ua | But there is not kubuntu-active for arm, is it? Is it temporary? | 22:56 |
| int_ua | s/not/no/ | 22:56 |
| GrueMaster | It is still in its infancy. This (Beta 1) was the first release and only i386. | 22:56 |
| GrueMaster | Not sure if/when images for it will be built on arm. Packages are there. | 22:59 |
| int_ua | leaving now. Thanks for your help, GrueMaster and rsalveti :) | 23:04 |
