**** BEGIN LOGGING AT Fri Nov 26 02:59:58 2010 Nov 26 06:47:12 can anyone recommend a portable arm-based device for ubuntu that is under $200 and has wifi/touchscreen? I've seen a lot of stuff from different comapnies in hong kong, most of them look fairly shady :) Nov 26 07:35:00 is there a solution for the pixmap auxv detection through /proc under qemu? Nov 26 07:35:04 qemu-arm Nov 26 08:33:09 morning Nov 26 09:00:58 tmzt_g2root: There are ways to override what ld.so uses, but not auxv in general Nov 26 09:02:36 there's some proc support in qemu-arm though? Nov 26 09:02:59 I can probably just add what I need, I'm trying to track down a problem with X and need to see if hardware is a factor Nov 26 09:03:26 well, it's not ld.so, it's pixman reading from auxv itself Nov 26 09:04:38 pixman/pixman-cpu.c: fd = open ("/proc/self/auxv", O_RDONLY); Nov 26 09:04:39 pixman/pixman-cpu.c: while (read (fd, &aux, sizeof(Elf32_auxv_t)) == sizeof(E Nov 26 09:22:30 tmzt_g2root: Yes, qemu can't help with that Nov 26 09:22:38 tmzt_g2root: There isn't any proc emulation in qemu Nov 26 09:22:55 tmzt_g2root: You could not mount /proc and create a real directory there instead ;) Nov 26 09:22:56 so, return true? :) Nov 26 09:23:08 tmzt_g2root: You need qemu machine emulation Nov 26 09:23:10 well, qemu-system brings proc with it Nov 26 09:23:20 tmzt_g2root: Or use some env var to override the pixman detection Nov 26 09:23:25 ogra: qemu-system brings a kernel with it Nov 26 09:23:31 sure Nov 26 09:23:35 lool: it doesn't seem to have an override Nov 26 09:24:04 was starting to like chroot with qemu-arm, but a lot of things don't work Nov 26 09:24:51 nothing that requires real or fully emulated hardware, sure Nov 26 09:25:25 its good for rolling images from binaries or to test binaries Nov 26 09:26:14 if you have anything that depends on real HW its not your solution Nov 26 09:26:50 hmm, I think it implements the instructions though, depending on the -M setting, it just can't detect they're available Nov 26 09:26:53 I'll patch it Nov 26 09:26:59 pixman, not qemu Nov 26 09:27:12 no sens in slowing down every read() for one corner case Nov 26 09:27:27 somebody should learn to use libhwcap :) Nov 26 09:27:53 file a bug upstream ;) Nov 26 09:29:17 hmm, what's a good kernel for basic arm stuff on qemu-system-arm? Nov 26 09:29:22 I'm tired of versatile Nov 26 09:29:30 as far as armv7 Nov 26 09:30:35 versatile is the only one with the qemu solutionn we have in the archive Nov 26 09:31:05 there are other qemu builds we dont ship i.e. qemu-maemo7-omap Nov 26 09:31:08 err Nov 26 09:31:16 *qemu-maemo/-omap Nov 26 09:41:55 okay, so versatilepb works with an armv7 cpu? Nov 26 09:42:09 what kernel do you recommend for that, I only have the old debian one Nov 26 09:43:18 tmzt_g2root: We patch the kernel build to build versatile with armv7, but the real board doesn't have a v7 CPU Nov 26 09:43:28 tmzt_g2root: There's the Ubuntu versatile one Nov 26 09:44:00 okay, I've got qemu-maemo checked out, I'll look at ubuntu Nov 26 09:44:06 tmzt_g2root: Nov 26 09:44:09 http://ports.ubuntu.com/ubuntu-ports/dists/maverick/main/installer-armel/current/images/versatile/netboot/ Nov 26 09:44:27 okay, thanks Nov 26 09:44:50 tmzt_g2root: qemu-system-arm -m 128 -M versatilepb -kernel vmlinuz -cpu cortex-a8 Nov 26 10:06:38 lool: why doesn't this work? Nov 26 10:06:42 qemu-system-arm -m 128 -M versatilepb -kernel vmlinuz \ Nov 26 10:06:42 -cpu cortex-a8 -sd androix-glibc-arm.img \ Nov 26 10:06:42 -append "root=/dev/mmcblk0 rootwait console=tty0 init=/bin/sh" Nov 26 10:06:56 the img is a raw ext3 Nov 26 10:07:23 but it panics not seeing /dev/mmcblk0 if I use rootdelay=2, or just sits there if I use rootwait Nov 26 10:07:45 does that kernel/hardware not support -sd ? Nov 26 10:08:01 tmzt_g2root: I don't know Nov 26 10:08:04 oh, initrd Nov 26 10:08:09 maybe Nov 26 10:08:19 well, the initrd should definitely have the module Nov 26 10:22:05 lool: this works Nov 26 10:22:08 /usr/bin/qemu-system-arm -m 128 -M versatilepb -kernel vmlinuz -cpu cortex-a8 -append "root=/dev/sda" -hda androix-glibc-arm.img Nov 26 10:22:34 it seems that while kernel supports the mmc device, either qemu doesn't support -sd with versatile or it doesn't have mmcblk support for some reason Nov 26 10:41:40 tmzt_g2root: what does pixman tries to find out that way? Nov 26 10:42:16 if the vfp or neon instructions are there Nov 26 10:43:04 tmzt_g2root: thats buildtime or runtime? Nov 26 10:43:13 runtime Nov 26 10:43:29 I think it uses something similar at buildtime though Nov 26 10:45:04 it is crosscompilable so no check on buildtime rather Nov 26 10:45:46 seems it was developerd when distros supported multiple isas on arm Nov 26 10:46:22 hmm.. OpenEmbedded has set of extra patches for pixman written by Nokia guys Nov 26 10:46:46 the HACK ones? Nov 26 10:47:21 no idea - just looked Nov 26 12:02:48 ndec, do you plan a call today (i will be the only canonical atendee, rest is on thanksgiving vacation) Nov 26 12:39:54 tmzt_g2root: Good to know, thanks Nov 26 14:07:08 I can not think of any possible explaination for this http://pastebin.com/Eaav97FC Nov 26 14:07:39 there's a weird bug that's only exhibited in the second instance, which is running in a chroot (test-2) Nov 26 14:08:11 I've reproduced the same thing with the Xvfb binary from xvfb in maverick on armv7 Nov 26 14:12:20 hi guys Nov 26 14:13:08 i have a wits a81-e wich seems to be built with an beagle board and omap3 cpu overclocked at 800 mhz with 256 mb of ram Nov 26 14:13:42 anyway i'm comming to you cause it seems it could be possible to use ubuntu on it as an sd boot Nov 26 14:13:57 https://wiki.ubuntu.com/ARM/OMAPMaverickInstall Nov 26 14:14:25 i'm not the type of guy to go asking directly before searching Nov 26 14:14:46 it now makes one week i'm working every evenings on it Nov 26 14:16:01 thats why i'm comming to you in order to maybe find the one that'll make ubuntu work on that 200 tablet wich rocks by the way with Android Froyo 2.2 and flash 10.1 Nov 26 14:17:06 jacquesdptd: url to product? Nov 26 14:17:11 that's why and also because i read it, i'm sure ubuntu can start on it as another guy managed already to launch angstrom but in a different way than the installation instruction Nov 26 14:17:14 yes Nov 26 14:17:16 one sec Nov 26 14:18:24 in fact it's a witstech but here is the link of the reseller : http://mp4nation.net/catalog/index.php?main_page=product_info&cPath=68&products_id=430 Nov 26 14:18:53 if you wanna check the manufacturer page www.wistech.com.cn Nov 26 14:18:59 hrw: can you think of a case where two processes have mapped the same binaries but show different logical behave, and the failure mode is not random? Nov 26 14:19:15 just take a look i'll then tell you what's happening when applying every intruction Nov 26 14:19:31 jacquesdptd, well, do you have a kernel and bootloader ? using the ubuntu rootfs shouldnt be a probelm Nov 26 14:20:03 jacquesdptd: but 256MB ram will hurt Nov 26 14:20:19 tmzt_g2root: I am not programmer Nov 26 14:21:01 256M wont be much fun, yeah Nov 26 14:22:04 but like av500 said once: show me source of larger pop modules... Nov 26 14:25:39 hm have you heard about linaro ? Nov 26 14:25:55 it boost any linux os for arm devices that really impressive Nov 26 14:26:25 i watched it turn on youtube on a beagleboard just like mine maybe even worse and it was surprisingly running perfectly Nov 26 14:26:39 ok i followed the official ubuntu page intruction Nov 26 14:26:52 where they are not talking at all about rootfs Nov 26 14:27:14 assuming i know i could try the rootfs solution and make my saucage alone Nov 26 14:27:55 but as they are proposing a preinstalled and perfect image, i don't see why it shouldnt work, just finished instruction gonna try again to boot the sd card Nov 26 14:28:07 i gave you all links in order to see intructions i'm following Nov 26 14:28:13 maybe there's one missing Nov 26 14:28:34 well, its unlikely that the default omap3 ubuntu kernel works out of the box on your device Nov 26 14:28:40 thtis one https://wiki.ubuntu.com/ARM/OMAP/ Nov 26 14:29:09 also the bootloader setup we use is focused on beagles Nov 26 14:29:54 and download link Nov 26 14:29:55 http://cdimage.ubuntu.com/ubuntu-netbook/ports/releases/10.10/release/ Nov 26 14:30:04 i understand totally what you mean Nov 26 14:30:25 i'm using ubuntu for 7 years Nov 26 14:30:48 well the thing is it sure does something as the screen doesn't light up at all on my device Nov 26 14:30:56 so much longer then I do ;D Nov 26 14:31:13 and without inserted sd, it does boot and light up Nov 26 14:31:24 hrw, even longer than ubuntu exists ;) Nov 26 14:31:44 thats not a problem, but just to tell i'll understand fzst what you'll explain me Nov 26 14:32:02 ogra_ac: nice :D Nov 26 14:32:28 jacquesdptd, well, as i said above, the kernel on our images will likely not boot on your device Nov 26 14:32:44 nor will the bootloader config work out of the box Nov 26 14:32:51 and could you help me find the right kernel ? Nov 26 14:33:02 first i would have liked to see at least the bootloader Nov 26 14:33:10 then i wouldd have gone into searching the right kernel Nov 26 14:33:14 no, you need to ask the manufacturer of your device for the correct patches Nov 26 14:33:37 for the bootloader you likely need some kind of serial access to your device Nov 26 14:33:49 if they use u-boot Nov 26 14:33:52 but how can i find the bootloader, could i give you the link for typicall flash files for Android on my device that way you could tell me wich correspond to wich Nov 26 14:33:58 if they dont that will get more tricky Nov 26 14:34:35 but as hrw already said, running ubuntu on a 256M device will be dog slow Nov 26 14:34:52 wow cool Nov 26 14:34:55 new firmware update Nov 26 14:34:56 we are fully focusing on 512M devices Nov 26 14:34:57 just saw it Nov 26 14:34:59 http://bbs.witstech.com.cn/dispbbs.asp?boardid=10&id=3104&page=0&star=2 Nov 26 14:35:05 well at the end of the page Nov 26 14:35:13 (or bigger) Nov 26 14:35:24 but i saw ubuntu mobile running perfectly Nov 26 14:35:48 why are they saying 256 is sufficient, do you know linaro ? Nov 26 14:36:00 yes, we all do Nov 26 14:36:15 linaro does most of its development in the ubuntu archive Nov 26 14:36:26 we use plenty of their work Nov 26 14:37:00 (half of the people in this channel are linaro guys) Nov 26 14:37:04 ;D Nov 26 14:37:10 http://www.youtube.com/watch?v=0r_eBSywKOg&feature=player_embedded Nov 26 14:37:24 * ogra_ac has no flash on his arm laptop Nov 26 14:37:27 that rocks, i was really happy to see that Nov 26 14:38:05 ogra_ac: html5? Nov 26 14:38:09 in any case i think its unlikely that linaro has a working kernel for your device either Nov 26 14:38:25 hrw, works fine on the test pages, doesnt work on youtube at all Nov 26 14:38:50 first i would like to know how to fix the boot loader in order to see anything when trying to flash Nov 26 14:38:55 hrw, http://camendesign.com/code/video_for_everybody/test.html i can watch that fine Nov 26 14:39:05 then i would search for the right kernel Nov 26 14:39:17 jacquesdptd, first get a serial connection working Nov 26 14:39:19 if only i had a serial port Nov 26 14:39:33 i have no Nov 26 14:39:52 also for linaro questions, probably ask in #linaro Nov 26 14:40:03 good idea Nov 26 14:40:07 but for the boot loader Nov 26 14:40:11 (though they wont have support for your device either) Nov 26 14:40:18 without any serial port it wont be possible to do anything ? Nov 26 14:40:31 you wont be able to adjust anything Nov 26 14:40:47 they are mentionning to support the exact board i have in my device Nov 26 14:40:54 so if it has a hardcoded setup to boot android its unlikely that you can easily work around that Nov 26 14:40:56 that's why i falled on them Nov 26 14:41:17 well, then let them help you Nov 26 14:41:35 i dont think they support much beyond beagle igep2 and n900 for omap3 Nov 26 14:42:10 you are taking bad the fact i'm saying that in the video i just gave you the link of upper they are showing how to use linaro with a beagle board as example , Nov 26 14:42:11 ? Nov 26 14:42:46 you know i'm searching for help, not for a winner that would have better solution and would advice me to go see those who better knows Nov 26 14:42:48 no idea, as i said, my arm netbook doesnt have flash Nov 26 14:42:52 i cant see your video Nov 26 14:43:00 that's why then Nov 26 14:43:09 i know they support beagles Nov 26 14:43:12 as we do Nov 26 14:43:18 then i do tell it to you if you neither can't read the webite Nov 26 14:43:27 (only the ones with 512M though( Nov 26 14:43:49 linaro might also support the lower specced ones Nov 26 14:44:01 that doesnt help you with your kernel or bootloader though Nov 26 14:44:28 their userspace is identical to ours Nov 26 14:44:37 we only differ in kernels Nov 26 14:44:38 well first, i would like to achieve this goal wih can be achieved with people helping me, then i'll see if it is too slow, the goal is to build tablets with ubuntu emmbed for ppl who wants it for less than 200 box Nov 26 14:44:46 and in the way we build images Nov 26 14:44:59 but i'm maybe alone to be trying to help the ppl discover it Nov 26 14:45:24 i understand Nov 26 14:45:53 their image build process is more complex, you need to build your image on your own or assemble it from different bits Nov 26 14:46:10 but as i said, with my exact board i saw ubuntu running, ppl have even managed to run 10.04, but it seems 10.10 could be even a lot better Nov 26 14:46:17 we provide ready made images in ubuntu but only for a certain set of boards Nov 26 14:46:18 they didn't report any lag by the way Nov 26 14:46:42 only problems of hw drivers such as bluetooth etc......... Nov 26 14:46:47 well, all i can say is talk to linaro in #linaro Nov 26 14:46:58 ok thx a lot Nov 26 14:47:10 if they have support for your board as you say then they should be able to help you Nov 26 14:47:18 would have been cool to find at least the solution for your bootloader Nov 26 14:47:26 but as you dont have any flash Nov 26 14:47:27 ?? Nov 26 14:47:39 the bootloader doesn't show anything Nov 26 14:47:46 i think the problem is about resolution Nov 26 14:47:52 800x400 Nov 26 14:48:08 but on files given officially i do not know at all how and wich to modify Nov 26 14:48:19 well, if the beagle bootloader is supposed to work on your device, feel free to adjust boot.scr Nov 26 14:48:28 it carries the resolution settings Nov 26 14:48:34 that's what i wanted to know Nov 26 14:48:39 how does it work ? Nov 26 14:48:48 how to adjust boot.scr ? Nov 26 14:48:48 you need to adjust the kernel cmdline Nov 26 14:48:57 just by editing it ? Nov 26 14:48:59 its linked from the wiki somewhere Nov 26 14:49:00 no Nov 26 14:49:04 ok Nov 26 14:49:09 phone Nov 26 14:49:20 k Nov 26 14:49:30 i think i got the page Nov 26 14:49:47 i collected more than 20 pages on the subject this week Nov 26 14:50:26 seeing that i was not alone in my quest and that some people maybe smarter than me understood how to make it work , but would prefer to do it alone Nov 26 14:51:19 as i said , achieving this little dream to be able to sell an Ubuntu Mobile version Tablet for 200 box would be really cool Nov 26 14:51:47 assuming i'm gonna try those new cortex a9 dual core that seems to be very very promising Nov 26 14:53:06 eh. Nov 26 14:54:44 then you are saying, there a way to modify a line in the boot.src file (wch is not existing in my flash files when i do flash for android and firmware) and to tell him to adujst resolution ? Nov 26 14:55:02 just read it Nov 26 14:55:08 i'm sure that if the boot loader would launch i would go straight to the right kernel Nov 26 14:56:21 BIG STUPID ME Nov 26 14:56:22 https://wiki.ubuntu.com/ARM/BeagleEditBootscr Nov 26 14:56:27 i'm sure you all do agree Nov 26 14:56:36 how comes i didn't saw it in a week Nov 26 14:56:39 sorry :// Nov 26 14:58:24 it wont help you with the bootloader in NAND though, it will only help you if the device runs a bootloader from SD too Nov 26 15:00:13 hrm ? Nov 26 15:00:17 sure Nov 26 15:00:24 i just wanna start ubuntu from sd Nov 26 15:00:26 as said Nov 26 15:01:02 which means that your bootloader in NAND needs to support that Nov 26 15:01:05 as said Nov 26 15:01:42 but try it yourself Nov 26 15:02:38 oh i understand Nov 26 15:02:42 that's why Nov 26 15:02:57 setenv bootcmd 'mmc init;fatload mmc 0 0x82000000 boot.scr;source 0x82000000'; setenv autostart yes; saveenv; boot Nov 26 15:03:08 they are talking about modified nand on the page Nov 26 15:03:19 that's what you are talking about right ? Nov 26 15:03:23 no Nov 26 15:03:33 iÄm talking about the bootloader installed on your device Nov 26 15:04:10 it does work the same, throught flashing Nov 26 15:04:18 with mlo files and all on sd Nov 26 15:04:20 the line above is clearly for a beagleboard with u-boot preinstalled Nov 26 15:04:30 you dont have a beagleboard Nov 26 15:04:38 ok Nov 26 15:04:47 anyway as said upper ppl managed to launch angstrom and ubuntu 10.04 Nov 26 15:05:00 ok i understand Nov 26 15:05:01 then just try to adjust boot.scr and check Nov 26 15:05:13 but as i'm not booting from inside nand Nov 26 15:05:16 btu from sd Nov 26 15:05:21 idon't understand Nov 26 15:05:47 just adjust the line and try Nov 26 15:06:37 ok, thx a lot for your help, a friend of mine just arrived Nov 26 15:07:47 i'll come back later, i do appreciate a lot the fact you tried to help me questino after question without loosing control as it can happen sometimes Nov 26 15:08:22 by the way i've been the first guy to start ubuntu on iphone 3g Nov 26 15:08:31 www.youtube.com/jacquesdupontd Nov 26 15:08:40 i hopefull for the bench of my tablet Nov 26 15:09:03 bbl Nov 26 19:07:36 How long should Maverick be displaying "Uncompressing Linux... done, booting the kernel." before it does something else? Nov 26 19:07:49 I'm using a BeagleBoard rev C3 Nov 26 19:14:23 try restarting, I've had that before with beagle. sometimes it just fails to boot Nov 26 19:14:34 (it shouldnt wait there more than a few seconds) Nov 26 19:14:54 think changing uboot helped me Nov 26 19:17:03 ahh, ok, so an hour is way to long Nov 26 19:17:53 thanks topfs2 Nov 26 19:20:27 np :) Nov 26 20:07:58 Kamondelious, depends where you look Nov 26 20:08:13 on a serial console an ubuntu image will never show anything more by default Nov 26 20:08:29 on HDMI/DVI it should move on Nov 26 20:43:53 ogra, oh! ok, thanks Nov 26 20:44:51 I didn't turn it on as I expected to see more Nov 26 20:47:35 hahaha, yeah it seems to be working, need to set the screen res so I can see it, but Ctrl+Alt+Del reboots it from the attached keyboard Nov 26 20:47:39 so that's a good sign Nov 26 20:51:20 oh right, forgot that ubuntu doesn't have serial by default :) Nov 26 20:51:30 that one got me also :) Nov 27 00:37:53 anyone running ubuntu on the newest kindle? Nov 27 01:42:33 ogra_ac_, I think I need to alter my statement. Tried unity now, it seems rather nice Nov 27 01:46:13 lot of stuff left to do but yeah it shares quite a bit with gnome shell **** ENDING LOGGING AT Sat Nov 27 02:59:58 2010
