Aksis it possible to load ubuntu on tablets10:49
Aksit has processor cortex A810:50
ogra_thats a pretty vague question10:50
Aksi have tablet pc which runs on android10:52
Aksi want it to works with ubuntu10:53
Aksis it possible to remove android and load ubuntu on it10:53
ogra_well, if you have access to the bootloader , have the kernel source and know how to set both of these up, installing ubuntu is usually possible10:53
ogra_first get the two first bits resolved, then come back10:54
Aksi have kernel source but i don't know to how to access bootloader10:57
morphisAks: it's usually fastboot you can use for this10:58
morphiswith fastboot support you can boot a different kernel than the flashed one shipping a special init-script to boot from an ext2 image on the internal flash disk10:59
ogra_if your bootloader isnt locked down by the vendor10:59
morphisthats the best (and safest) way to get this done10:59
ogra_(which it is on many tablets)10:59
morphisogra_: yes, thats the condition to be able to do this10:59
LetoThe2ndi'd suggest rephrasing - it is usually doable under these preconditions, but still requires considerable knowledge and is no click here, click there process.11:00
Aksi have 2.6.36-8-omap3 kernel m i be able to boot it using fast boot?11:00
morphisyou need the kernel source special for the tablet you have11:00
ogra_is your tablet an omap3 device ?11:00
morphisAks: look at this http://git.shr-project.org/git/?p=meta-smartphone.git;a=blob;f=meta-samsung/recipes-bsp/chroot-script/chroot-script/init.sh;h=4ad32a66258bd1163efe908608e65f37dc5b4c09;hb=HEAD11:01
Aksyes its on omap and i have kernels source .11:01
morphisfor a suitable init script11:01
Akscan you give me step by step description of installing ubuntu on any tablet ?11:02
LetoThe2ndnow thats exactly what i meant.11:03
morphisAks: thats not possible11:03
morphisAks: a tablet is no PC as you know it where you can install everything11:03
morphisit's build for a very special case, to run android11:04
Aksis there any hardware limitation ?11:04
LetoThe2ndAks: there are bits and pieces of information available, and solving the puzzle will eventually enable you to install ubuntu on a platform. but there's not step by step guide, nor does anyone want to give that.11:05
morphisAks: and you can't expect anything to work after you have ubuntu on the tablet11:06
LetoThe2ndso its sad but true: if you have to ask, it is not for you.11:07
morphisLetoThe2nd: :)11:07
LetoThe2ndam i sounding too pseudo-31337?11:08
ogra_no11:09
ogra_since you are right :)11:09
ogra_its technically possible to do what he wants but you need quite some skills that go beyond basics11:10
LetoThe2ndi know, i wouldn't be able to do it myself without a lot of effort.11:10
ogra_right, same here, and i do it as a day to day job11:11
morphisLetoThe2nd: it's which is not worth you spend it on this11:11
Aksya i am new to this so we want your help?11:11
LetoThe2ndmorphis: exactly, hence i do not even try.11:11
morphisLetoThe2nd: I did this for years now11:11
morphisstarted with the Palm Pre ended with the Nexus S11:12
morphisnot ubuntu11:12
morphisbut something else11:12
morphisit makes fun11:12
morphisbut you spend too much time on it and never really get usable results11:12
LetoThe2ndi think i got some good skills on arm linux, but in another direction. and i admit, exchanging android on a probably underdocumented device is not what i'd call fun to me.11:12
morphis:)11:13
morphisyou learn a lot11:13
LetoThe2ndbut i guess i can judge the skillset needed - and i do not sense this kind of schwartz in our young padawan here.11:13
morphis:)11:13
ogra_getting a working image for the toshiba ac100 took me several months ... and thats not even a tablet where you have to fight with the input setup too11:14
morphisit's bad but things are getting better with the years11:15
ogra_definitely ... mostly thanks to linaor who work on  unifying things like kernel and bootloader11:16
ogra_*linaro11:16
morphisyes, linaro is a great effort11:16

ppisatiogra_: thanks, closed13:16
ogra_:)13:16
ppisatiogra_: by any chance, did you try your beagle xm?13:20
ogra_no, i havent managed to get a properly working install still, will do a netboot server install now13:20
ppisatiogra_: what you mean?13:23
ogra_i only tested the desktop images dirung A213:23
ogra_and these all failed ... since then i havent touched my XM13:23
ppisatieven the omap3 desktop?13:24
ogra_yes13:24
ogra_the only working image we had during A2 was panda13:24
ppisatiso you saw the same problems i mentioned in the email?13:24
ogra_no, i couldnt get it booting iirc13:24
ppisatii had errors during bootup (on xm rev a)13:25
ppisatisquashfs errors&c13:25
ppisatiwhich rev do you have?13:25
ogra_also a rev a13:25
ppisatiah13:25
ogra_and i had seen the squashfs errors before but that was back when there were also USB and display issues13:26
ppisatianyone with a beagle xm, an empty sd card and willing to do some tests?13:26
ogra_i am, i just need to do an install first :)13:26
ppisatiogra_: why don't you try daily?13:31
ogra_because i was to lazy to zsync :P13:34
ogra_but yeah, i should probably do that to make sure they work13:34
ppisatiogra_: it seems to work on my rev c13:43
ppisatiogra_: but doesn't on rev q13:43
ppisati*a13:43
ppisatiogra_: if you have another rev a, and we reproduce the same problem13:43
ogra_hmm13:43
ppisatithat's a good hint13:43
ogra_right13:43
_william_do you know if there are any pla to release ARM repositories with the upcoming 12.10 ?13:44
ogra_well, i can surely say i saw the squashfs errors before13:44
ogra__william_, ?? we release arm repos since 3 years13:44
ppisatiogra_: ok, as soon as you can do another reinstall, that would be nice13:44
ppisatiogra_: moreover, do you know who has another xm?13:44
_william_ogra_: hu... what is the URL please ?13:44
ogra_ppisati, 3:21 to go for zsync ;)13:44
* _william_ feeling stupid ;)13:44
ogra_http://ports.ubuntu.com/13:45
_william_excellent ogra_ ! i've been looking for this along time until i came to this chan13:46
_william_even a few people from Canonical (i won't name ;) ) were not able to given me this url13:47
_william_thanks a lot13:47
ogra_welcome :)13:49
ogra_we also roll installable images for some architectures13:49
ogra_ppisati, hmm, apart from the fact that the spalsh is missing, the current daily looks fine to me13:57
ogra_no squashfs erros on boot this time13:57
ogra_(lets see how it behaves during copying)13:58
ogra_argh13:58
ogra_thats really messed up, it runs a live session !13:59
ppisatiexcept for the last comment, i assume it's working for you14:01
ppisatiright?14:02
ogra_right, i get into a fully functional live session14:03
ppisatiogra_: this one? http://cdimage.ubuntu.com/daily-live/current/quantal-desktop-armhf+omap.img14:04
ogra_yes14:04
* ppisati tries again14:04
_william_ogra_: so far i had only found images. Anyways... i'm going to try it over the next days. I'm trying to build a custom environnement based upon Armada chip14:05
ogra_armadaxp ?14:05
_william_armada 51014:06
_william_have you already tested with this processor ?14:06
ogra_isnt that armv6 ?14:07
ogra_(ubuntu only supports v7 and above)14:08
_william_according to marvell it is ARM v6/v7-compliant14:09
ogra_well, if its v7 it should work14:09
_william_http://www.marvell.com/application-processors/armada-500/14:09
ogra_(if you can force that mode somehow)14:09
_william_i'll get the answer soon ;)14:10
ogra_well, that page only say v714:10
ogra_they should make their mind up :P14:11
ogra_i guess you are good14:11
_william_500 is v7 only, 510 seems to be v6/v714:12
_william_let's test, i'll know it14:12

RoyKhrmf! seems my network doesn't work after updating my pandaboard ubuntu 11.10 to latest (not 12.04). iwconfig/ifconfig looks good, but no ping/arp/nothing works. no firewall setup. any idea how to reboot with an old kernel on this thing?15:20
ppisatiRoyK: ls -al /boot15:23
ppisatiRoyK: choose the preferred version/kernel15:23
ppisatiRoyK: sudo flash-kernel 3.2.0-omap415:23
ppisatiRoyK: if, for example, you want to use that kernel15:24
ppisatiRoyK: btw, which kernel are you using now?15:24
RoyK3.0.0-1211-omap415:25
RoyKerm... seems 3.1.0-1282 is installed, but not in use15:25

ppisatino wait15:33
ppisatiif you are using 3.1.0-1282 it's not our kernel15:33
ogra_no, thats from some TI PPA15:34
ogra_still, if it worked before ...15:34
RoyKtried it, and didn't work too well15:34
RoyKfound the error - PEBKAC15:37
ogra_remove it !15:38
ogra_ppisati, Snd_omap_soc_beagle ... geez !!15:42
ogra_what a mess15:42
* ogra_ just saw the mails15:42
ogra_ppisati, so even my netinstall has issues here ... i see lots of oopses and the NIC just hangs after a while (smsc95xx i think)16:40
* ogra_ will file a bug if this installation ever ends16:41
ppisatiogra_: omap4 or omap3?16:47

ppisatido i need a working video out? or i can everything from console?16:49
ppisati*can i do16:49

ogra_ah, that might be16:57
ogra_more udebs and udeb content16:57
ppisatiyep16:57
ppisatiwhere does it hang for you?16:58
ogra_well, i left it alone, but it was stuck at "selecting software" where it tried to access the net to pull down Packages.gz16:59
ogra_manually unloading the smsc driver and running dhclient eth0 fixed it ... but dmesg is full of oopses17:00

ppisatiok17:02
ppisatii'll go till the end then17:02
ppisatiit's partitioning17:02
ogra_yeah, just let it run ... might also be cause by idling ... i left it for like 45min before i checked again17:02

TypoNAMis anybody else having a problem where when I move my mouse pointer to the far right hand side edge in Unity desktop on Ubuntu 12.04 on pandaboard the mouse pointer completely disappears? I did ctrl+alt+F1 and then ctrl+alt+F7 to find just a completely white background canvas with my mouse pointer and nothing else is there as if my mouse got trapped in a second blank X11 session17:41
TypoNAMthe only way to get back into unity is to restart lightdm without rebooting :/17:42
ppisatiogra_: btw, it's still installing17:45
ogra_for me it failed again ...17:46
ppisati"Finishing the installation"17:46
infinityTypoNAM: I've never seen that with the default kernel and X drivers, no.  Are you using something fancy, like TI's PPA?17:46
ogra_lucky you17:46
ppisatidone17:46
ogra_to me it looks like the traffic on the USB hub makes it fall over17:46
ppisatibut it doesn't boot17:47
ogra_hooray, i made it past the point17:47
ppisatiit created an ext2 /.boot partition17:47
ogra_yeah, thats fine17:48
ppisatiand anoither ext3 for the rest17:48
ogra_ext3 ?17:48
ogra_sigh17:48
ogra_should be ext417:48
ppisatiext417:48
ogra_i think thats all NCommander's parted-uboot stuff17:48
ppisatiso it's a kamikaze instyallation17:48
ogra_which we seriously dont need17:48
ppisatiit does all the stuff it needs to do17:48
TypoNAMinfinity: just using powervr sgx graphics package, but nothing developmental17:48
ppisatibut it doesn't create the vfat boot partition17:49
ogra_well, we dont need an ext2 /boot17:49
ppisatiyep17:49
ppisatiit's so x8617:49
ppisatiand so old17:49
ogra_yep17:49
ogra_and we dont use it for anything :)17:49
ogra_all we use /boot for is to read kernel and initrd from there17:49
TypoNAMinfinity: I'm specifically using unity-2d (Ubuntu-2D option) since regular unity has rendering problems with pvr sgx enabled17:49
ogra_to put them into the vfat17:49
infinityogra_: Weeeeeell...17:49
ogra_or into flash17:50
infinityogra_: We don't need it if we use flash-kernel and stuff everything on the SD.17:50
ogra_or other presistant storage the board needs to boot17:50
infinityogra_: It becomes useful if you use bootz instead of bootm.17:50
ogra_why would that differ ?17:50
infinity(Like we do on the highbank machines)17:50
ogra_i mean, does bootz make any special use of /boot ?17:51
infinityYes.17:51
ppisatianyway, it freak me out that you have so many problems with your beagle17:51
infinityWe don't load from a vfat, we load from /boot17:51
ogra_oh, i thought its just a different bootm17:51
infinityWhich is sane and reasonable.17:51
ppisatiogra_: ^17:51
ppisatiogra_: have you tried serial installation?17:51
ogra_infinity, depends17:51
ogra_ppisati, not yet, and i seem to get through this time17:51
ppisatiogra_: but still17:51
ppisatiogra_: even if it fails just once17:52
ogra_infinity, if your uboot cant support something else than vfat you cant use /boot17:52
ppisatiogra_: it's something we should look at17:52
ogra_yes, i will file bugs and all ... once i have a proper system17:52
infinityogra_: extload is enabled in every uboot we ship.17:52
ogra_my dmesg if full of errors17:52
ogra_infinity, that does say nothing about OEM projects :)17:52
ogra_and i had my share of boot issues thanks to vfat /boot17:53
ogra_or rather dpkg issues17:53
ogra_if we once have a grub like bootloader (or even grub itself) i would go for /boot  ... as long as we go with uboot and flash-kernel, i wouldnt ... just adds the need for special casing again17:54
infinityogra_: vfat /boot is never the right answer.17:55
ogra_heh, no17:55
ogra_i learned that the hard way, years ago with my first classmatePC image17:55
