ruckuusHello everyone05:23
ruckuusI am trying to create Ubuntu rootfs for Samsung s3c6410 based board.05:25
ruckuusHow to specify the kernel to be used? --seed linux-image-???05:26

Tims_Hi, maybe some of you remembering me from yesterday. I can't get my Webcam working on an Gumstix Overo (omap3503). Unfurtunately I have to give the gumstix away, what they tell me just today.08:30
=== JamieBen1ett is now known as JamieBennett
Tims_So I hope there is anybody who can help me a little bit.08:32
Tims_The conclusion of yesterday was, that I have to build my one kernel08:32
=== Baybal_ is now known as Baybal
Tims_because everytime I try to install, for example "qc-usb-source"-driver, it end in failure due to the kernel, he cant find the one which is neccessarry08:34
Tims_but on the gumstix webpage I searched and found a kernel which fits from the kernel-number, but the error apeared further.08:35
LetoThe2ndprobably you don't have the kernels headers installed.08:37
LetoThe2ndfor understandment: you don't compile against a running binary kernel, but against its api. the api is in the headers. no headers - no compiling against the kernel.08:41
Tims_i installed kernel, maybe the wrong one, let me take a look08:48
Tims_i installed kernel-headers, maybe the wrong one, let me take a look08:50
LetoThe2ndTims_: hint for getting your thoughts going: you install a gumstix-specific kernel. you sound like you have installed the kernel-headers from the repo. how should the repo contain the headers fitting for your vendor kernel?08:59
Tims_It is installed linux-headers-2.6.32-21 and 2.6.32-2808:59
LetoThe2ndTims_: ok, and that should be enough to make you think. remember the kernel version number you told us yesterday?08:59
LetoThe2ndare they fitting?08:59
Tims_no, but I cant remove it09:00
LetoThe2ndthats not the point. point is, you need the headers fitting your running kernel. and thats where we come back to.... you already know it? wanna guess? right, documentation! :D09:01
Tims_the kernel which i get with uname and which i find in the debs are fittig, so maybe so only thing is to remove de wrong one09:01
LetoThe2ndyesterday you told us, you're running some whacked 2.6.34 or .35-overo. and thats certainly not fitting to 2.6.32-21/-28. right?09:02
Tims_yesterday! do you think I turning my thumbs here?09:04
LetoThe2ndhonest answer?09:04
LetoThe2ndand as of today you have not provided new information, i only can think yesterday infos are still uptodate.09:05
Tims_9:3509:05
LetoThe2ndTims_: "i installed kernel"... sorry, no information given which one.09:06
Tims_i said the one how fits, i thought the number is irrelevant if the fit09:08
XorA|gonepersia: ping09:11
LetoThe2ndTims_: honestly, i doubt your judgement on "fitting". :-)09:12
LetoThe2ndTims_: for a beginning you might name the _exact_ version of the running kernel, where it's from and how you have installed it.09:12
=== XorA|gone is now known as XorA
Tims_uname -a : Linux gumstix 2.6.32 #1 Thu Mar 18 22:40:54 PDT 2010 amv7l GNU/Linux09:15
Tims_i get it from here: http://www.sakoman.com/feeds/omap3/glibc/images/overo/09:16
LetoThe2ndTims_: i see neither a -21 nor a -28. so: guessing time again... fitting or not fitting?09:17
Tims_i don't know where or how I can find/see the last number09:18
LetoThe2ndTims_: if it's not there, it's not there. in the case of ubuntu, they mark the service releases.09:18
LetoThe2ndTims_: so one might think that a header set fitting some ubuntu-service-fixed kernel doesn't match some downloaded-from-the-internet-kernel. and one might be right.09:19
LetoThe2ndTims_: seriously, you got to get a grip on the information you're providing and the assumptions you are making. productive support is nearly impossible the way you do things.09:20
persiaXorA, Hey.  Sorry I missed you yesterday.09:31
XorApersia: no problem, was just going to say Im going to be in your part of the world next week09:33
persiaOh, excellent.  Which days?09:33
XorApersia: landing saturday morning tokyo, leaving the next saturday afternoon09:34
persiaWe'll have to meet up then :)09:34
XorApersia: that would be cool09:34
Tims_LetoThe2nd: sorry, i can't gave you more information as the system me gave,09:41
LetoThe2ndTims_: i repeat. you assumed a fitting kernel - which isn't there. you didn't mention - you actually installed a new kernel. neither did you name the source of it, if you have built it yourself, the version... nothing. have to ask again and again and again to get the information out of you (or thin air, not much of a difference) and clearing up what you think about your system and is just not true is sooo timeconsuming and irksome that t09:45
LetoThe2ndi think i'll give it up, now. good luck - to the supporter and the supported. you'll need it.09:46
Tims_cu09:47
persiaDo gumstix boot the kernels in the repo cleanly?  I wouldn't think one would need a special kernel.09:51
ograpersia, alst time i saw one trying it broke on the MMC09:53
ogra*last09:53
persiaUgh.  That ought get fixed, if reasonably feasible.09:53
ograi think it cant, afaik the gumstix uses some kind of incompatible MMC driver09:54
ograbut it might have been fixed, not sure09:54
persiasource-incompatible or config-incompatible?09:54
ogrampoirier was working on it09:54
ograi think source09:54
ograbut i dont know much about it09:54
persiaThat's very annoying.  Oh well.09:54
ogratalk to mpoirier if it ever got fixed09:55
ruckuusHello All. Has anyone tried Ubuntu-arm on samsung s3c6410 based board?09:55
persiaHe's not here so much anymore :(  But I'll hunt him down sometime.09:55
ograruckuus, i think the guys in #linaro use some samsung boards, try there09:55
persiaruckuus, I've not heard of anyone trying to get a kernel for that into the archive, but my knowledge isn't all-inclusive.09:56
ograpersia, he is regulary in #linaro09:56
ruckuusogra, thank you so much. is that a channel?09:56
ograyes09:56
ruckuusI saw working one here: http://www.arm9.net/mini6410-ubuntu.asp09:56
ruckuusogra, thank you I will try to get there09:57
persiaruckuus, Unless you know the folk who made an image, I'm not sure I'd trust it entirely.09:57
ruckuuspersia, well me too. I download the images and will try it soon09:57
persiaruckuus, OK.  Be aware that we'll be dropping support for 9.10 in a couple months.09:58
ruckuusIs it "that simple" as mentioned in Ubuntu RootStock to create Ubuntu rootfs image?09:59
persiaruckuus, You could do that, and the result is something you can probably trust a bit more.09:59
ruckuusI have everything from the BSP but still fuzzy on how to put the specified kernel09:59
=== zyga_ is now known as zyga
persiaYou will need to stuff in your own kernel, etc.09:59
ruckuuspersia, sounds optimistic. Thank you10:00
ruckuusI have created rootfs with Poky (PokyLinux) and it works well10:00
ruckuusI am interested to put Ubuntu on top of the board, will be easier to develop i guess10:00
persiaruckuus, I don't know anything about your board, but you'll want to make sure it supports at least ARMv7a: if it does, you should be fine.  If not, I'll recommend Debian.10:00
ruckuuspersia, my board is OK6410 http://www.arm9board.net/sel/prddetail.aspx?id=348&pid=20010:01
ruckuusI guess that would be simple to put Ubuntu on top of that, but my current issue is how to use my own kernel10:02
persiaBased on http://en.wikipedia.org/wiki/ARM11 , that looks like it's not a good fit for Ubuntu.10:02
ruckuuspersia, thank you for the link, I will check it10:03
persiaYou'll likely have a much better experience running Debian, as you'll be able to run current software, upgrade, etc.10:03
ruckuuspersia, could you please point me out why you come to that conclusion? TIA10:04
ruckuuspersia, I guess so. I am using Debian now10:04
persiaWikipedia says that the Samsung S3C64x0 series of processors is ARM11, and indicates these support the ARMv6 instruction set.10:04
persiaUbuntu, since Lucid (10.04) requires that hardware support the ARMv7a instruction set, which means that you won't be able to run any of the recent releases.10:05
ruckuuspersia, ... for media support (only) ? no?10:05
persiaIt's about the compiler defaults: if you don't have support for the instruction set, the software won't run.10:06
ruckuuspersia, I see. meaning to say if I want to put Ubuntu, I will need to build everything from scratch using supported compiler that comes with BSP10:07
ograimagine i386 vs i686 ... optimized i686 code wont run on i386 because the i386 CPU doesnt know some instructions the i686 one uses10:08
persiaAnd you have no promises the results will work, as the source has often been modified to expect more recent processors.10:08
ruckuusogra, persia, I get it10:08
ruckuushello, it is confirmed that my board only support ARMv6 instruction set. Said on the website it can only run Ubuntu up to 9.1010:39
hrwruckuus: install Debian then10:46
ruckuushrw, I will. Currently I am using Debian packages from scratchbox10:47
ruckuusIs there a link for me to study how to achieve it?10:48
hrwruckuus: use Debian directly. my brain shutdowns when I hear scratchbox word10:48
hrwruckuus: use rootstock/multistrap to generate armel image of debian and boot it with your kernel10:48
ruckuushrw, whew seems scratchbox is too traumatic for you :\10:49
hrwruckuus: long story10:49
ruckuushrw, i see. Thank you10:49
ruckuushrw, I almost died with scratchbox, then switch to Poky, but still PITA when adding new package, and just today I saw posting that Ubuntu can run on ARM10:50
ruckuusvery helpful, hopefully10:50
persiaIn terms of the development experience, Debian and Ubuntu are nearly identical.11:09
persiaThe differences tend to be small patches for individual packages, based on differing philosophies about how the distribution is delivered.11:09
persiaBut the key is to run Debian as Debian, rather than trying to cross-compile Debian on scratchbox or something.11:10
danger89Hi11:41
danger89I bought the iGEP v2 hardware board with WIfi+ Bluetooth11:42
danger89Can somebody say how good the Ubuntu netbook port for ARM is?11:43
danger89For example does all the hardware components works on the igep v211:44
hrwiirc it works with 10.10 or 11.0411:46
danger89Yes, I believe it will work. But does all the hardware components work OK with the 10.10? Like: Wifi, Bluetooth, i2c, USB, etc.?11:51

rsalvetiNCommander: ogra: unity-2d seems to be working with latest qt12:46
ograyay12:46
rsalvetithe only thing to fix is that I'm not seeing the places icon that is used to fire up new applications12:47
ogrado yu see it elsewhere ?12:47
ograi think the places implementation isnt ready yet12:47
rsalvetiwell, at least it was working at my maverick machine12:47
ogra(the unity one, not the 2d one)12:47
rsalvetithat icon with scissors12:47
ograyeah, it was redone in natty12:48
rsalvetioh, ok12:48
ograwe need to compare to x86 now i guess12:48
rsalvetiyup12:48
ograindicators and places were rewritten12:48
ograand the desktop switched to dconf12:48
ograthats the three bits still to be done in natty for unity-2d12:48
rsalvetiyou mean, for unity-2d?12:49
ograeverything switched to dfconf12:49
ogra*dconf12:49
ogragconf is out12:49
rsalvetiyeah, true12:49
ogra(though might be that dconf is just a different frontend, i didnt really look into that, upstream will care)12:49
danger89ogra: why should I use the alfa 2 over the "daily build" of Ubuntu netbook 11.04? Why is it better? And I checked the datum, but the daily build is from 9 feb and alfa 2 is from 2 feb.12:49
danger893 feb*12:49
ogradanger89, alphas usually get a week of archive freeze and QA12:50
ogradailies can be broken in various way and are usually not regulary tested12:50
ogra*ways12:50
danger89So alfa 2 is the latest version of 11.04 and it is stable?12:51
ograit was tested for the install to work at least12:52
danger89^^12:52
ogradailies only get tested occasionally12:52
danger89ok thx12:52
danger89ogra: If you got the igep v2 board. What would you  choose for OS version (10.10 vs 11.04 or.. something completly else)?13:01
ograno idea, i have no igep2 :)13:02
ograbut the later the better i would say, since its more likely the kernel works better with that HW13:02

martynMarvell announced a chip back in Nov, and theoretically a 'development platform' .. but so far I haven't met or seen any evidence of one...17:22

rsalvetijanimo: I believe the x-loader update issue was supposed to be fixed with the version we're currently using19:12
rsalvetijanimo: when you updated your files, did you copy both x-loader and u-boot or just x-loader?19:13
janimorsalveti, both19:13
rsalvetiif this is still an issue, we should also report it19:13
rsalvetiif not able to fix it, then recreating the first partition would be the best solution19:13
janimorsalveti, well it may have been the copying to wrong location in VFAT, as I simply copied the files over (after renmaing the old ones to .bak(19:14
rsalvetijanimo: hm, what happens when you copy the one to .bak and overwrite it?19:15
janimorsalveti, I'll do some more thought out tests, I recovered form yesterday's by rewriting the whole SD card19:15
janimoas that too showed kernel errors19:15
janimoso it may not be an xloader bug at all19:15
rsalvetihm, ok19:16
ograrsalveti, i think only the issue with x-loader not finding u-boot after overwriting it was supposed to be fixed19:16
ografi the fat changes you will still have issues with the rom code19:17
rsalvetiogra: could be19:18
rsalvetineed to test it more to see what exactly is the issue now19:18
janimoogra, the new packages are to be added to the image in livecd-rootfs?19:18
ograwe need to seed them19:19
janimowe have no specific seeds for the images right?19:19
ogra(that should be a workitem)19:19
ograthere is a seed for kernels and the like iirc19:19
ograwe have ubuntu-netbook exclusively for armel19:20
ograworst case we can seed it there19:20
ograbut that wont cover minimal installs indeed19:20
ograand there is also a prob with subarches, seeds dont know about them19:21
ograso we need to install *all* x-loader and u-boot packages19:21
ograplatform.natty/boot might be an appropriate seed19:24
janimoogra, all those packages are for omap based boards now?19:24
janimoogra, the seed should be arm specific  I guess19:24
ograand a hack in livecd-rootfs to remove the unwanted bootloader19:24
ograno19:24
ograthe seed needs to be general but the line in the seed should be armel onl19:25
ogray19:25
* janimo needs to find out what line in the seed means19:25
* janimo checks ubuntu seeds19:25
ograso i would suggest adding u-boot and x-loader to platform.natty/boot (after talking with cjwatson) and then having a hack in livecd-rootfs to remove the unwanted ones19:26
ograsimilar to the hack that removes the unwated headers there19:26
janimoogra, ok19:26
ograthe boot seed also carries grub for example19:26
GrueMasterWould it make sense to have a meta file and seed it?19:28
ograwe use seeds to produce meta packages normally19:28
GrueMasterOh?  I was thinking like with the kernel we have linux-ti-omap19:29
ograi dont think the u-boot packages have the version in the package names19:30
GrueMasterNot that I have a clue about the voodoo needed for seeds/image creation.19:30
ograu-boot-linaro-omap3-beagle and u-boot-linaro-omap4-panda19:30
ograso we dont need a meta19:30
GrueMasterok19:30
ograsame for x-loader: x-loader-omap3-beagle and x-loader-omap4-panda19:31
ograwe just need to seed them in the right place and remove what we dont need during rootfs build19:31
ograbah, and now janimo is gone19:59
ograbad timing19:59
GrueMasterHe definitely needs a caching irc proxy.20:00
ograyes20:02
ograso after discussion with lool in #linaro i see that we cant seed it but need a different approach20:03
