| dholbach | good morning | 07:17 |
| dholbach | 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 | 08:47 |
| janimo | dholbach, TBH the last ARM sessions did not seem very successful :) | 08:47 |
| janimo | either too techniocal or lack of hw makes people shy I guess | 08:48 |
| dholbach | hrm | 08:48 |
| * janimo checks the session names | 08:48 | |
| dholbach | maybe it'd help to advertise it in ARM/mobile specific lists and so on | 08:50 |
| janimo | we only have ubuntu-devel as a ml AFAIK? | 08:57 |
| janimo | or you mean outside ubuntu? | 08:57 |
| dholbach | wherever ARM/Ubuntu people hang out :) | 09:00 |
| janimo | dholbach, this is the only dedicated channel, the mailing list is ubuntu-devel as it pertains to ubuntu as a whole | 09:04 |
| dholbach | ok | 09:04 |
| janimo | I am just not sure what ARM specific thing we could disucss because it would either be too technical | 09:04 |
| janimo | or if not, than not ARM specific | 09:05 |
| janimo | anything that is different on ARM should be low level details of plumbing and kernel which few people know or care about | 09:05 |
| dholbach | 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 :) | 09:09 |
| janimo | that is true, cdimage people like ogra and infinity know most about making images | 09:09 |
| janimo | would be a nice session to hold if we had easy to use tools to roll your own image | 09:10 |
| janimo | but there is none, besides scripting together debotstraap or live-build and which makes it error prone | 09:10 |
| dholbach | 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 | 09:11 |
| dholbach | (as an idea...) :) | 09:11 |
| janimo | I am mostly thinking about what session could we have that people walk away from with info they can apply | 09:11 |
| janimo | rather than just finding out trivia about ubuntu development :) | 09:11 |
| janimo | or at least that is what my impression was about the goals of open weeks, maybe I misunderstood partly :) | 09:12 |
| janimo | oh by the way, happy birthday | 09:12 |
| * janimo hugs dholbach | 09:12 | |
| dholbach | thanks a lot janimo :) | 09:13 |
| dholbach | well what you do HAS to do with development :) | 09:13 |
| janimo | 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 | 09:16 |
| dholbach | 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 | 09:16 |
| janimo | I wonder why no QML/phone SDK sessions there though | 09:16 |
| janimo | 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 :) | 09:17 |
| dholbach | janimo, I just thought that with all the great stuff coming up regarding Ubuntu on ARM there must be a story we can tell | 09:47 |
| dholbach | at least one | 09:47 |
| dholbach | :) | 09:47 |

| ogra_ | dholbach, putr me in, i'll make something up about image building (and re-packing the nx7 image) | 10:29 |
| dholbach | ogra_, 30m? 1h? Thu 31st Jan - 17:30 UTC? | 10:30 |
| ogra_ | 30m for a "talk" plus 30 for Q&A ? | 10:31 |
| janimo | ogra saves the ARM team's honor again. \o/ | 10:31 |
| ogra_ | not sure i can fill the second half | 10:31 |
| ogra_ | heh | 10:31 |
| * ogra_ goes afk to shovel a ton of snow ... *sigh* | 10:32 | |
| dholbach | ogra_, thanks a bunch! I'll put you in there | 10:37 |
| reisei | ogra_: what type of rootfs image for nexus7 ? squashfs? | 11:18 |
| janimo | reisei, ext4 last time I installed | 11:21 |
| janimo | it is not a live image but a form of preinstalled - last I checked at least | 11:22 |

| focus_well | Anyone know if there is ubuntu distro available for IMX6Q Sabrelite board? | 15:58 |
| ogra_ | focus_well, iirc linaro has ubuntu images for it, ask in #linaro | 15:59 |
| focus_well | 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 | 16:02 |
| ogra_ | ah, well, we never had an mx6 image in ubuntu | 16:03 |
| ogra_ | there were mx5 ones but they wont run on mx6 | 16:03 |
| focus_well | I am hoping to make something from sources for mx6 - are there going to be big problems (not expert at this)? | 16:04 |
| focus_well | pardon my ignorance, can the sources for mx5 be worked on to make it work on mx6? | 16:05 |
| focus_well | or is it down to lack of documentation that keeps mx6 from a decent ubuntu supported CPU? | 16:06 |
| focus_well | The iMX6Q (quad core) has come down in price to about $20 - opens up a lo of possibilities. | 16:07 |
| ogra_ | mx5 cant be made to work on mx6 | 16:08 |
| ogra_ | well, the images cant, you will need a different u-boot and kernel | 16:08 |
| focus_well | ogra_: Ah! So its just documentation and compiling to march mx5 into mx6? | 16:09 |
| ogra_ | i know ppisati looked into addint devicetree support for mx6 to our current raring kernel, not sure where he got his image from exactly | 16:09 |
| ogra_ | (for the userspace) | 16:09 |
| focus_well | 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? | 16:12 |
| Tassadar | quad core for $20? that is crazy Oo | 16:12 |
| ogra_ | focus_well, indeed, yes | 16:13 |
| ogra_ | you could also make something up on top of ubuntu-core if you are experienced | 16:13 |
| focus_well | Tassadar: http://uk.farnell.com/freescale-semiconductor/mcimx6q5eym10ac/mpu-i-mx6-quad-1ghz-624fcbga/dp/2253171 | 16:13 |
| ogra_ | the sabre is an awesome board | 16:13 |
| ogra_ | and ++ for actual SATA | 16:14 |
| Tassadar | oh, I thought you meant the whole board | 16:14 |
| focus_well | ogra_: I am in the game to make an open source KiCAD SO-DIMM board with the iMX6Q and release it free of charge | 16:15 |
| hrw | ogra_: I would say -- for freescale | 16:15 |
| hrw | I have a feeling that freescale produces cpus and do not care at all about supporting them | 16:16 |
| ogra_ | depends how you define support | 16:16 |
| ogra_ | if your definition is release a half finished BSP and move on to the next project, then they actually do support it :P | 16:17 |
| focus_well | 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. | 16:18 |
| hrw | ogra_: ;DD | 16:18 |
| hrw | ogra_: that's their definition indeed | 16:18 |
| ogra_ | :) | 16:18 |
| focus_well | Tassadar: Sorry I meant chip price is $20 for quad core. Dual and single core chips probably a lot cheaper | 16:19 |
| focus_well | I already try to start project with AllWinner A10 CPU - but their lack of documentation is putting the whole thing through sticky syrup | 16:20 |
| hrw | focus_well: who cares about single/dual when quad is 20$? | 16:20 |
| focus_well | Now that the quad core is $20, I'm thinking the AllWinner at $10 is not competitive | 16:20 |
| ogra_ | hrw, makes of industrial stuff probably | 16:21 |
| ogra_ | *makers | 16:21 |
| focus_well | 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 | 16:21 |
| ogra_ | if your 600MHz beagle B1 like chip is capable enough you wont use any dual core solution | 16:21 |
| focus_well | But I need Ubuntu ported to it. What are my realistic prospects? | 16:21 |
| ogra_ | for running some sensors in your factory or whatever | 16:22 |
| ogra_ | focus_well, well, userspace will just run OOTB | 16:22 |
| ogra_ | you need to make up the kernel and bootloader bits for it though | 16:22 |
| focus_well | 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. | 16:23 |
| Tassadar | Is like an actuall datasheet available for that processor? | 16:24 |
| focus_well | 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 | 16:25 |
| ogra_ | intresting project | 16:26 |
| Tassadar | focus_well: that seems like a pretty expensive thing to build | 16:26 |
| focus_well | I already do all that work in software for cheap A10 matchbox computer - http://www.gplsquared.com/mk802/mk802.html | 16:26 |
| focus_well | I got stuck trying to get sources for all that Linux and datasheets for the A10. | 16:26 |
| focus_well | Dragging on 6 months | 16:26 |
| ogra_ | A10 is crap | 16:27 |
| * ogra_ isnt a fan ... | 16:27 | |
| focus_well | These days the CPU + display + RAM etc under $30 BOM costs | 16:27 |
| wookey | surely it's better than the Pi chip? | 16:28 |
| Tassadar | even the touchscreens? Oo | 16:28 |
| wookey | which is the competition in that price bracket | 16:28 |
| ogra_ | wookey, my ipaq is better than the Pi chip :P | 16:28 |
| focus_well | Touch screen $7 for 4.3" - $13 for 7" | 16:28 |
| * Tassadar is looking at the pi which is quetly sitting on his router, working as a dlna server | 16:29 | |
| Tassadar | wau, that is quite low Oo | 16:29 |
| Tassadar | hmm | 16:29 |
| focus_well | Tassadar: CN factory prices - need to order 1000+ usually to get prices like that | 16:30 |
| Tassadar | that CPU can't be soldered by hand, you need board made in factory...that kinda limits the "everyone can make one" | 16:31 |
| focus_well | 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? | 16:32 |
| ogra_ | well, as i said, the userspace should work OOTB | 16:32 |
| ogra_ | depends how well you can work out bootloader and kernel for your device | 16:33 |
| focus_well | Tassadar: just need a reflow oven - about $600 or less | 16:33 |
| focus_well | ogra_: What does 00TB mean? | 16:33 |
| ogra_ | out of the box | 16:33 |
| ogra_ | ubuntu userspace will run on pretty much every armv7 SoC | 16:34 |
| focus_well | Ah! I get it - so all I need is command line to be working on the board and the rest is just userspace?!?!?!? | 16:34 |
| ogra_ | no, you need a kernel and a bootloader that work | 16:34 |
| wookey | comand-line _is_ userspace -) | 16:34 |
| Kuschelwolle | Herzlich Willkommen in der Freiheit! Kein Kick Kein Ban nur Fun! lg Lukas #ubuntu-de-offtopiic | 16:34 |
| focus_well | OK | 16:34 |
| ogra_ | the bootloader boots, loads the kernel, the kernel gets executed and then mounts the root filesystem which contains the usersapce | 16:35 |
| ogra_ | the last bit here will just work | 16:35 |
| focus_well | OK | 16:35 |
| ogra_ | everything before the mounting needs to come from you (or someone) | 16:35 |
| focus_well | OK - the boot loader - might be able to rework this - http://www.eewiki.net/display/linuxonarm/i.MX6x+SABRE+Lite | 16:36 |
| focus_well | 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 | 16:37 |
| focus_well | Thanks guys for the chat. | 16:42 |
