**** BEGIN LOGGING AT Wed Jan 16 02:59:59 2013 Jan 16 05:52:09 I'm presently trying to trigger a script after I press the power button on my TF101.. I know the button's keycode from running "xev".. All I need is to know what what to put in the place of in xmodmap -e "keycode 142 = " Jan 16 05:52:18 anyone's got an idea? Jan 16 05:53:57 keycode is 124, by the way.. I inverted 2 numbers Jan 16 07:17:05 good morning Jan 16 08:47:04 ogra_, janimo: do you think it'd make sense to do something ARM- or enablement-specific for UDW? we still have 3 open 30m slots: https://wiki.ubuntu.com/UbuntuDeveloperWeek/Timetable Jan 16 08:47:49 dholbach, TBH the last ARM sessions did not seem very successful :) Jan 16 08:48:13 either too techniocal or lack of hw makes people shy I guess Jan 16 08:48:59 hrm Jan 16 08:48:59 * janimo checks the session names Jan 16 08:50:14 maybe it'd help to advertise it in ARM/mobile specific lists and so on Jan 16 08:57:06 we only have ubuntu-devel as a ml AFAIK? Jan 16 08:57:11 or you mean outside ubuntu? Jan 16 09:00:18 wherever ARM/Ubuntu people hang out :) Jan 16 09:04:28 dholbach, this is the only dedicated channel, the mailing list is ubuntu-devel as it pertains to ubuntu as a whole Jan 16 09:04:52 ok Jan 16 09:04:55 I am just not sure what ARM specific thing we could disucss because it would either be too technical Jan 16 09:05:01 or if not, than not ARM specific Jan 16 09:05:31 anything that is different on ARM should be low level details of plumbing and kernel which few people know or care about Jan 16 09:09:03 I just wondered if it might be interesting to talk about how in general ubuntu is brought to a new device and everything is enabled, images made and so on - I mean you are the experts - there's a lot people don't know about what you do :) Jan 16 09:09:51 that is true, cdimage people like ogra and infinity know most about making images Jan 16 09:10:13 would be a nice session to hold if we had easy to use tools to roll your own image Jan 16 09:10:51 but there is none, besides scripting together debotstraap or live-build and which makes it error prone Jan 16 09:11:20 or maybe an overview over what the arm/mobile/device people do - just a description of the work that goes into it - there's a huge variety of things and it might be interesting to learn more about what's going on behind the scenes Jan 16 09:11:23 (as an idea...) :) Jan 16 09:11:35 I am mostly thinking about what session could we have that people walk away from with info they can apply Jan 16 09:11:48 rather than just finding out trivia about ubuntu development :) Jan 16 09:12:20 or at least that is what my impression was about the goals of open weeks, maybe I misunderstood partly :) Jan 16 09:12:37 oh by the way, happy birthday Jan 16 09:12:41 * janimo hugs dholbach Jan 16 09:13:43 thanks a lot janimo :) Jan 16 09:13:56 well what you do HAS to do with development :) Jan 16 09:16:00 it is development sure, I am just thinking it is nowhere near as readily described and copied/applied as a topic on packaging for example Jan 16 09:16:34 sure, but you always have that - some sessions are hands-on, clear-cut, others are an introduction to what a team is doing which might generate more interest Jan 16 09:16:38 I wonder why no QML/phone SDK sessions there though Jan 16 09:17:26 I am just basing my belief on the ARM FTBFS session I gave last year where I think only you asked a question to break the awkward silence :) Jan 16 09:47:08 janimo, I just thought that with all the great stuff coming up regarding Ubuntu on ARM there must be a story we can tell Jan 16 09:47:09 at least one Jan 16 09:47:10 :) Jan 16 10:29:51 dholbach, putr me in, i'll make something up about image building (and re-packing the nx7 image) Jan 16 10:30:37 ogra_, 30m? 1h? Thu 31st Jan - 17:30 UTC? Jan 16 10:31:15 30m for a "talk" plus 30 for Q&A ? Jan 16 10:31:19 ogra saves the ARM team's honor again. \o/ Jan 16 10:31:26 not sure i can fill the second half Jan 16 10:31:37 heh Jan 16 10:32:19 * ogra_ goes afk to shovel a ton of snow ... *sigh* Jan 16 10:37:13 ogra_, thanks a bunch! I'll put you in there Jan 16 11:18:05 ogra_: what type of rootfs image for nexus7 ? squashfs? Jan 16 11:21:25 reisei, ext4 last time I installed Jan 16 11:22:00 it is not a live image but a form of preinstalled - last I checked at least Jan 16 11:27:13 janimo: thanks. Jan 16 12:24:45 hi is there a distro image available i would like to install buntu to my superpad but unsure on how to go about it anyhelp would be appreciated Jan 16 13:19:26 infinity: can you take a look at alsa-{lib,utils} in {precise,quantal}-proposed queue and accept them? Jan 16 14:00:53 meh nexus7 needs charging. Jan 16 15:58:35 Anyone know if there is ubuntu distro available for IMX6Q Sabrelite board? Jan 16 15:59:33 focus_well, iirc linaro has ubuntu images for it, ask in #linaro Jan 16 16:02:47 ogra_: that was my first destination but they say they discontinue it and there are no distros to download from their Sabrelite web site https://wiki.linaro.org/Boards/MX6QSabreLite Jan 16 16:03:07 ah, well, we never had an mx6 image in ubuntu Jan 16 16:03:18 there were mx5 ones but they wont run on mx6 Jan 16 16:04:19 I am hoping to make something from sources for mx6 - are there going to be big problems (not expert at this)? Jan 16 16:05:15 pardon my ignorance, can the sources for mx5 be worked on to make it work on mx6? Jan 16 16:06:03 or is it down to lack of documentation that keeps mx6 from a decent ubuntu supported CPU? Jan 16 16:07:23 The iMX6Q (quad core) has come down in price to about $20 - opens up a lo of possibilities. Jan 16 16:08:11 mx5 cant be made to work on mx6 Jan 16 16:08:26 well, the images cant, you will need a different u-boot and kernel Jan 16 16:09:13 ogra_: Ah! So its just documentation and compiling to march mx5 into mx6? Jan 16 16:09:39 i know ppisati looked into addint devicetree support for mx6 to our current raring kernel, not sure where he got his image from exactly Jan 16 16:09:49 (for the userspace) Jan 16 16:12:47 Saberlite did come with some sort of Linux, so if I got hold of the sources for that, I'd be able to compare and work out what to do? Jan 16 16:12:54 quad core for $20? that is crazy Oo Jan 16 16:13:15 focus_well, indeed, yes Jan 16 16:13:35 you could also make something up on top of ubuntu-core if you are experienced Jan 16 16:13:46 Tassadar: http://uk.farnell.com/freescale-semiconductor/mcimx6q5eym10ac/mpu-i-mx6-quad-1ghz-624fcbga/dp/2253171 Jan 16 16:13:48 the sabre is an awesome board Jan 16 16:14:00 and ++ for actual SATA Jan 16 16:14:32 oh, I thought you meant the whole board Jan 16 16:15:37 ogra_: I am in the game to make an open source KiCAD SO-DIMM board with the iMX6Q and release it free of charge Jan 16 16:15:47 ogra_: I would say -- for freescale Jan 16 16:16:16 I have a feeling that freescale produces cpus and do not care at all about supporting them Jan 16 16:16:46 depends how you define support Jan 16 16:17:12 if your definition is release a half finished BSP and move on to the next project, then they actually do support it :P Jan 16 16:18:00 ogra_: so its possible to just copy the circuit of the Sabrelite which is available online - chop unecessary bits (just have micro SD to boot + RAM + minimal bits) and then make the rest of the pins available out through the 200 pin SO-DIMM edge connector + fpc connectors. Jan 16 16:18:29 ogra_: ;DD Jan 16 16:18:37 ogra_: that's their definition indeed Jan 16 16:18:45 :) Jan 16 16:19:17 Tassadar: Sorry I meant chip price is $20 for quad core. Dual and single core chips probably a lot cheaper Jan 16 16:20:17 I already try to start project with AllWinner A10 CPU - but their lack of documentation is putting the whole thing through sticky syrup Jan 16 16:20:18 focus_well: who cares about single/dual when quad is 20$? Jan 16 16:20:45 Now that the quad core is $20, I'm thinking the AllWinner at $10 is not competitive Jan 16 16:21:15 hrw, makes of industrial stuff probably Jan 16 16:21:19 *makers Jan 16 16:21:36 So if I make a SO-DIMM board, with quad core, and release all the circuit diagrams in KiCAD which is free for anyone to use, they can make their variants and sell it or whatever Jan 16 16:21:49 if your 600MHz beagle B1 like chip is capable enough you wont use any dual core solution Jan 16 16:21:54 But I need Ubuntu ported to it. What are my realistic prospects? Jan 16 16:22:05 for running some sensors in your factory or whatever Jan 16 16:22:26 focus_well, well, userspace will just run OOTB Jan 16 16:22:42 you need to make up the kernel and bootloader bits for it though Jan 16 16:23:35 I wanted to have a proper tablet like computer with a speech and touch LCD with lots of GPIO pins and completely working open sourced KiCAD drawings and PCB so that anyone can go make product with it free of charge. Jan 16 16:24:01 Is like an actuall datasheet available for that processor? Jan 16 16:25:12 I plan to port Gambas IDE so a Visual basic like software runs on the CPU + espeak - so the thing doesn't need any buttons - it accepts inputs from buttons designed on Gambas programs, and output is visual + voice Jan 16 16:26:05 intresting project Jan 16 16:26:06 focus_well: that seems like a pretty expensive thing to build Jan 16 16:26:09 I already do all that work in software for cheap A10 matchbox computer - http://www.gplsquared.com/mk802/mk802.html Jan 16 16:26:49 I got stuck trying to get sources for all that Linux and datasheets for the A10. Jan 16 16:26:56 Dragging on 6 months Jan 16 16:27:37 A10 is crap Jan 16 16:27:49 * ogra_ isnt a fan ... Jan 16 16:27:53 These days the CPU + display + RAM etc under $30 BOM costs Jan 16 16:28:04 surely it's better than the Pi chip? Jan 16 16:28:21 even the touchscreens? Oo Jan 16 16:28:23 which is the competition in that price bracket Jan 16 16:28:37 wookey, my ipaq is better than the Pi chip :P Jan 16 16:28:44 Touch screen $7 for 4.3" - $13 for 7" Jan 16 16:29:28 * Tassadar is looking at the pi which is quetly sitting on his router, working as a dlna server Jan 16 16:29:40 wau, that is quite low Oo Jan 16 16:29:52 hmm Jan 16 16:30:13 Tassadar: CN factory prices - need to order 1000+ usually to get prices like that Jan 16 16:31:31 that CPU can't be soldered by hand, you need board made in factory...that kinda limits the "everyone can make one" Jan 16 16:32:20 So if I commit to make an iMX6Q board, is there a good chance by the end of the year I can get the software working? Jan 16 16:32:47 well, as i said, the userspace should work OOTB Jan 16 16:33:00 depends how well you can work out bootloader and kernel for your device Jan 16 16:33:02 Tassadar: just need a reflow oven - about $600 or less Jan 16 16:33:37 ogra_: What does 00TB mean? Jan 16 16:33:55 out of the box Jan 16 16:34:16 ubuntu userspace will run on pretty much every armv7 SoC Jan 16 16:34:24 Ah! I get it - so all I need is command line to be working on the board and the rest is just userspace?!?!?!? Jan 16 16:34:38 no, you need a kernel and a bootloader that work Jan 16 16:34:52 comand-line _is_ userspace -) Jan 16 16:34:53 Herzlich Willkommen in der Freiheit! Kein Kick Kein Ban nur Fun! lg Lukas #ubuntu-de-offtopiic Jan 16 16:34:58 OK Jan 16 16:35:09 the bootloader boots, loads the kernel, the kernel gets executed and then mounts the root filesystem which contains the usersapce Jan 16 16:35:17 the last bit here will just work Jan 16 16:35:24 OK Jan 16 16:35:37 everything before the mounting needs to come from you (or someone) Jan 16 16:36:25 OK - the boot loader - might be able to rework this - http://www.eewiki.net/display/linuxonarm/i.MX6x+SABRE+Lite Jan 16 16:37:22 Compiling and getting the kernel to work will then be the hardest of the hardest part - I can spend months on it if that is what it takes Jan 16 16:42:10 Thanks guys for the chat. Jan 17 02:51:33 anyone know if any of the -M options for qemu-system-arm support more than 1 nic? **** ENDING LOGGING AT Thu Jan 17 03:00:00 2013
