ppisatiericm|ubuntu: the target to get a binary for a beagleboaard on natty/master is binary-omap, right?10:56
ericm|ubuntuppisati, I believe so11:00
ericm|ubuntuppisati, cooloney should know more detail11:00

dokoogra_, janimo: the test rebuild for armel did finish for main, now building the universe packages. however I would like to start another test rebuild using gcc-4.6 for main, setting the priority of this test rebuild higher than the current running rebuild for universe12:45
dokook with you?12:45
dokoonce gcj-4.6 is built12:45
janimodoko, fine by me. There are not many important uploads remaining12:54
dokook, thanks12:54
* ogra_ wishes we could exclude packages on demand for such rebuilds13:03
ogra_doko, fine with me, though if all big packages jump on the buoldds at the same time and lock all buildds i'll ask lamont to kill a build13:04
dokoit's done alphabetically13:04
dokoand if you are interested, you should be able to set the priority for single remaining builds13:05
ogra_ah, i didnt know, yesterday we only had two left, the rest was taken by things like thunderbird, firefox, eglibc gcc etc ...13:05
ogra_yeah, i know, doesnt help if all buildds are taken by packages that take more than a day13:05
ogra_go ahead, just be aware that i'll ask lamot to kill stuff if its urgent and the rebuild is blocking13:06
ogra_(i assume things will get retried anyway if they are killed)13:07

arun_has anyone noticed a problem with the gcc-4.5-arm-linux-gnueabi package for natty? it has an unmet dependency: "Depends: libgcc1-armel-cross (>= 1:4.5.2-8ubuntu3cross1.47) but 1:4.5.2-8ubuntu1cross1.61 is to be installed"14:51
loolhrw: ^14:54
arun_i think it's a recent problem. i updated the toolchain this morning.14:54
hrwyes, we know that14:58
hrwI have a talk with steve in <1h so we will discuss this too14:59
arun_hrw, cool. thanks.15:02

GrueMasterheadless images fail to start oem-config.16:22
GrueMasterdebconf database is locked apparently.16:23
=== prpplague_afk is now known as prpplague
GrueMasterogra_: I am going to have to fail the headless images due to bug 758858.16:45
ogra_GrueMaster, hrm16:56
ogra_netbook looks fine apart from one jasper issue with the ppa icon that i need to fix16:57
GrueMasterI just booted netbook.  Appears to be ok so far.16:59
ogra_it feels quite a lot slower though16:59
GrueMasterHmmm.  oem-config died near the end on my netbook image.17:03
GrueMasterGenerating a bug report now.  Not sure if it is reproducable yet (these types of failures take ~30 minutes to reproduce).17:05
ogra_didnt die for me here17:06
ogra_did you get an apport report ?17:07
GrueMasteryes.  Looking over the logs now.  I also have a stack trace.17:07
ogra_very strange17:07
GrueMasterogra_: bug 758910.  I'm going to reflash and retry.17:11
ogra_GrueMaster, you say it restarted, did it finish on the second run ?17:24
GrueMasteryes17:24
ogra_hmm, itz gtk boog i'd say17:25
GrueMasterGrumble.  Need a proper German translator bot.  :P17:26
ogra_lol17:26
ogra_well, keep an eye on it, but i doubt we'll see it again17:26
ogra_i did three installs already and havent seen it17:26
GrueMasterI'm reflashing & retrying now.  Unfortunately my desktop system tends to degrade over time flashing sd cards and I end up having to reboot.17:27
ogra_bah17:27
GrueMasterHmm.  Running evolution, firefox, amarok, kde desktop, two VM's in virtualbox and flashing an sd card seems to low my system down a bit.17:33
GrueMasterloagavg:  5.9017:34
ogra_on the panda ?17:35
GrueMasterPfft.  Panda doesn't do VM.17:36
ogra_ah, indeed :)17:37
GrueMasteroh, as to the win32 image writer my son developed for jaunty, we are on our own if we want to add functionality to it.  He is too busy to help before summer.17:38
GrueMasterI'll see if I can get Ncommander to look at it before release.17:39
* ogra_ takes a short break and will then jump into headless mode ...17:44
* GrueMaster thought that was ogra_'s standard modus operendi. 17:47

GrueMasterNice.  My panda is now detecting my wireless AP on the other end of the house.  With no antenae.18:02
ogra_there is an antenna on the PCB18:03
GrueMaster(also detecting my neighbor's wifi.  Mua haha).18:03
ogra_the socket is just for an extender18:04
GrueMasterAh.18:04
ogra_i couldnt get bT to work though18:04
ttyandroidhi all18:04
ttyandroidubuntu-arm works with Devkit8000?18:04
GrueMasterttyandroid: Possibly.  Try downloading the latest natty headless image to start with.  We also have a netbook image as well.  May need to replace x-loader & u-boot, but the rest of the pool should work fine.18:09
ttyandroidMany thks GrueMaster18:09
GrueMasterttyandroid: Be aware that since it is essentially a beagle, not an XM, memory will be a major limitation.18:11
ttyandroidGrueMaster:   i have buy one BeagleBoard-XM A3 and stop working18:12
GrueMasterHW failure?18:12
ttyandroidGrueMaster yes mmc card18:13
ttyandroidGrueMaster: i try to buy other Beagleboard-XM but not find18:13
GrueMasterThe card or the card reader?18:13
ttyandroidGrueMaster: card reader18:13
GrueMasterOuch.18:14
ttyandroidGrueMaster u-boot bin from original SD don't work18:14
ttyandroidGrueMaster: no load other u-boot.bin  and console seems nothing18:14
GrueMasterWhich image are you trying?18:15
ttyandroidGrueMaster original SD image18:15
ograoh, intresting !18:15
GrueMasterogra_: ???18:16
ograon headless i see asoc set up the sound stuff correctly18:16
ttyandroidGrueMaster: Angstrom-demo-image18:16
ograon netbook i still had the old errors18:16
ttyandroidGrueMaster have another seller of BeagleBoard-xM ?18:16
* ogra doesnt get that18:16
GrueMasterogra_: that is very odd.18:17
GrueMasterttyandroid: I'm in the US.  I just used Digikey.18:18
ograGrueMaster, http://paste.ubuntu.com/593227/18:18
GrueMasterWTH???18:19
GrueMasterI'll check it here, since I have two boards to play with side by side.18:19
ograyeah, confusing, isnt it ?18:19
ograheadless was built last while netbook was built first in a chunk of ten image builds or so18:20
GrueMasterI wonder if it is because of the alsa-utils stuff we added post-maverick?18:20
* ogra goes to check the manifests18:20
ograthats a good idea .... i'm just noticing that headless doesnt have any alsa userspace stuff18:21
ograi bet TheMuso carried that over from maverick18:22
GrueMasterSilly little aussie.  :P18:22
ograwell, nobody told him to drop it :)18:23
ograhmm, there are no processes at all on the headless image18:23
ograi dont get why it would fail18:23
GrueMasteroem-config?  Don't know either.18:24
ograbah, crap ...18:25
* ogra forgot he has no job control in the rootshell18:25
ograstarting over18:25
=== Lopi is now known as usb26
=== usb26 is now known as Lopi
GrueMasterogra_: Interesting tidbit.  I removed /usr/share/alsa/init/omap4 and after a reboot, I now have no dmesg errors relating to asoc.  Checking to see if sound works.19:12
ogra_GrueMaster, that would be awesome19:15
GrueMasterNo sound.  Mucked with alsamixer controls, nothing.19:20
GrueMasterHaven't tried the patches and updates you have yet.19:21
ogra_ah, well, you will need the new pulse from people.c.c19:22
rsalvetitried with new pulse and nothing19:25
ogra_i get a new device in the sound properties19:25
ogra_but it only provides an input device apparently19:26
ogra_i sadly dont have the time to play more with wound today19:26
ogra_*sound19:26
ogra_will have to wait until post beta19:26
ogra_well, in any case dropping the maverick scripts should be a step forward19:28
ogra_GrueMaster, do you remember when we had the last working headless images ?19:31
GrueMasterBeta 1.19:31
* ogra_ tries to figure out the uboquity changes that might have caused this 19:31
ogra_i'm pretty sure there were images after b119:32
ogra_but i dont know for how long19:32
GrueMasterI have all dailies since Beta.  Haven't been able to test them as I was hobbled last week.  I can do a binary test and see where the point of failure started.19:34
ogra_i would guess with april 3rd19:35
ogra_i see two debconf related changes in the ubiquity upload from the 2nd19:36
GrueMasterOk, starting there.19:37
GrueMasterogra_: 20110403 fails19:57
ogra_if 02 works i think i know what it is19:58
ogra_i'll try to remove that code bit here, lets see what happens then19:59
GrueMasterChecking 02 now.20:00
GrueMaster(as well as juggling a mirade of other test images).20:00
GrueMaster02 passes.20:07
GrueMasterSo the relevant version of oem-config is 2.5.32->2.5.3320:08
ogra_yep20:11
ogra_+  * Do a quick check at startup to see if the debconf database is locked by20:12
ogra_+    something else, and exit slightly more gracefully than by raising an20:12
ogra_+    exception (LP: #746020).20:12
ogra_thats what i suspect to be at fault20:12
* ogra_ tests20:13
GrueMasterIs there a tool to check the debconf db?20:14
ogra_no idea20:14
GrueMasterCould be a simple boolean error.20:14
ogra_i dont think there is a tool20:15
ogra_works !20:15
* ogra_ is at the language selection screen 20:15
ogra_aaaand ... install successfully finished \o/20:22
ogra_yup, all fine, even after a reboot20:24
GrueMasterYou mentioned that jasper is doing something with debconf?20:30
ogra_yes, but it does that since before beta120:31
ogra_and it does it before the reboot, i already asked colin if it could cause any issue, but he denied20:31
ogra_it only sets debian-installer/framebuffer to false20:32
ogra_i simply think the check is worng, but i wouldnt know how to write it different or better20:33
ogra_i fear we need cjwatson20:33
steevhey all, i have an arm machine that unless the hdmi cable is plugged in, it freezes during boot.  i've set the console to equal our serial console, and i added debug=vc to the kernel command line... and it appears it gets to this point: + /scripts/init-top/plymouth20:37
steevand then it stops20:37
GrueMasterWhat is the platform?  Image?20:38
steevuImage, Maverick, ARM mx51520:38
GrueMasterI don't think we had an mx515 kernel for maverick.  I know we didn't have images.20:39
GrueMasterMight check with #linaro folks.20:39
loolThe Linaro kernel supports some mx515 boards, but I guess it's a custom kernel20:39
steevyou know it is lool :P20:39
loolsteev: This is in the initrd still; plymouth touches framebuffer (it outputs the boot progress splash and messages etc.)20:40
loolsteev: To poke at what's happening, you can add break=something to your kernel cmdline, this will give you a shell in the initrd20:40
loolsteev: rgrep maybe_break /usr/share/initramfs-tools to see possible breakpoints you can use20:40
steevlool: my understanding was that, plymouth was supposed to see if it could use a framebuffer and if not (ttymxc0) was supposed to go down to a text console, it doesn't appear to be going to a text console20:41
loolsteev: For instance, break=top is a good choice to get started20:41
steevokay, ill give that a shot :)20:41
loolsteev: I can't speak for what plymouth attempts to do, you might have to research this yourself; but I can tell you how to run things by hand  ;-)20:41
steevwell if i can step through it, that will point where i need to go :)20:42
loolsteev: To read the sources, take the initrd.gz from the system and unpack it in a directory of your choice: mkdir i; cd i; gunzip -c < ../initrd.gz | cpio -i20:42
loolsteev: That will give you the same contents as what's in the initrd from the shell you will have20:42
loolsteev: You can run exactly the same shell commands to see at which points it goes wrong20:42
steevis there a way to make plymouth itself be a tad more verbose, like saying what it's attempting to do?20:56
ogra_GrueMaster, see -release ... fix underway ;)21:02
GrueMasterI've been monitoring it.  Cool.21:03
ogra_:D21:03
ogra_so apart from sound we should be good now21:03
GrueMasterYep.21:03
ogra_and the odd color change in headless :)21:03
GrueMasterI still don't see that.21:04
ogra_i still wonder why only i seem to see it21:04
ogra_snap :)21:04
ogra_but i see it on all machines, its not client bound ... else i would have blamed the ac10021:04
GrueMasterMaybe it looks different when not viewed through a beer glass.21:04
ogra_hmm, i should try that21:05
GrueMasterheh21:05
* ogra_ goes to look for a whisky botte to replace the glass21:05
ogra_*bottle21:05
ogra_GrueMaster, but do you use screen ?21:06
GrueMasterscreen+byobu21:06
ogra_(i think i remember you said byobu)21:06
ogra_that might apply colormap changes21:07
GrueMasterWell, the system that the serial console is hooked to is headless.  So ssh->byobu->many screen sessions.21:08
ogra_ah21:08
ogra_i wouldnt mind having it b/w21:08
ogra_i wonder if there is a way to enforce that on the installer side21:08
steevwhere does /conf/param.conf come from (we don't have one, which is why i ask)21:17
GrueMasterogra_: I'm going to go ahead and greenlight armel rebuilds after oem-config is fixed.  I haven't found anythhing that is critical and no one on kubuntu is interested in testing prior to rebuild.21:19
ogra_GrueMaster, yeah, just go ahead, i'll test tomorrow as soon as i get up21:20
GrueMasterThat will really help, as I have an am post-op appointment tomorrow.21:20
ogra_no prob21:20
rsalvetieven when setting up the postfix (calling debconf) the colors were weird21:42
rsalvetipink and gray IIRC21:43
ogra_mine are completely inverted21:43
ogra_rendering the whole ui unreadable21:43
rsalvetiyeah, seems to be inverted21:43
ogra_https://bugs.launchpad.net/bugs/747229 has screenshots21:44
GrueMasterWow.  I am definately not seeing that.21:45
GrueMaster(of course, I am currently not seeing much of any oem-config atm)  :P21:46
ogra_heh21:46
Schamushi is anyone available to help me with a Ubuntu 10.10 ARM/OMAP question?22:05
SchamusRun into a bit of a problem working with the USB connection22:05
GrueMasterSchamus: Give more details.  What are you seeing?22:10
SchamusQuite right, I'm running a Beagleboard xM A3,with ubuntu 10.10. I'm coding a python script to manipulate an LCD screen via USB22:10
SchamusThe python script uses import serial, sets up the connection, and shoots hex bytes controlling and manipulatingthe screen to show items, however, on the beagleboard its apparently not sending the information over correctly22:11
GrueMasterOk.  Not sure how much help we can be.  have you tried this on x86 first?22:11
SchamusOn any other laptop this script works perfectly, but the beagleboard does not22:11
SchamusSo i was curious if USB drivers on the Ubuntu 10.10 ARM edition are a bit different than a standard Ubuntu 10.10 install22:12
GrueMasterThey should be the same.  I believe the kernel was the same for both x86 & armel.  Could be a config issue though.22:12
SchamusHow so?22:13
GrueMasterCheck /bot/config-`uname -r`22:14
GrueMasterboot22:14
GrueMasterThe code is the same tree as x86.  If it is a usb issue, it is either in the core arch code or a missing config option.22:15
GrueMasterThe rest is arch generic.22:15
GrueMasterAlso, try the latest maverick kernel or the natty kernel.22:16
Schamusyeah i did updates yesterday22:16
Schamusso, excuse my amateur, you mean something like "gedit /boot/config-'uname -r' correct?22:19
GrueMasteryes22:19
GrueMaster(you can actually just use tab completion, but it was easier to type uname -r to indicate the config for the running kernel)22:20
Schamusyeah i've been picking up linux over the past month or two so i'm a little ignorant in some basics still22:21
Schamusim pulling up a blank with that command22:23
GrueMastertype 'ls /boot-config*'.  That should give you a list of config files.22:24
GrueMasterLook at the latest one.22:24
SchamusAh, got it now.22:26
Schamusis there a specific section im looking at for USB?22:26
GrueMasterI have no idea personally.  I don't have one of these lcd screens to try to reproduce this issue with.22:27
GrueMasterWhat image are you running on your laptop?  If it is running the same release, check to see if it has the same kernel rev.22:28
GrueMasterThat is the easiest starting point.22:28
Schamus10.04 on my laptop, 10.10 on the beagleboard22:30
GrueMasterI would suggest upgrading the laptop.  It will be easier to diagnose that way.22:30
GrueMasterYou can also just download the iso and use usb-creator to make a bootable usb drive to test with.22:31
SchamusYeah, I mean I tried many other USB devices, (i.e. bluetooth dongle, mouse, keyboard) and they all work, just this LCD screen doesn't seem to want to accept streams from the beagleboard22:32
Schamuscould it be a problem with permissions?22:34
