applepiCan anyone point me toward the kernel configuration that ubunutu armhf was built with?  I'm attempting to boot my freescale imx6sl-evk with an ubuntu armhf rootfs, but I can't seem to get all the way through.15:22
rbasakapplepi: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-trusty.git;a=tree;f=debian.master/config;hb=HEAD15:24
applepirbasak: thanks :)  ah, just noticed Thumb2..  I don't have that on in my kernel..  should I be able to get the imx6sl up and going with that on?15:29
rbasakI have no idea, sorry. I just happened to have needed to dig into the kernel config before.15:30
applepiah okay, thanks.15:30
Valduareanyone here have an mk80815:55
Valduareor 802 or 802_a10s15:55
nuit123I'm using Ubuntu (in reality, just the networking piece), none of the desktop stuff) on a PC and now want to shrink it all, preferably to a chip not a board.  Any embedded gurus in here?18:20
rbasak!anyone18:22
ubot2`A high percentage of the first questions asked in this channel start with "Does anyone/anybody..." Why not ask your next question (the real one) and find out? See also !details, !gq, and !poll.18:22
nuit123:-)18:22
nuit123i'm looking for a Linux and tiny computers (SoC/board) seasoned expert who can advise on the best way to get Linux networking running on the smallest and least expensive hardware.18:25
nuit123!details18:25
ubot2`Please give us full details. For example: "I have a problem with ..., I'm running Ubuntu version .... When I try to do ..., I get the following output: ..., but I expected it to do ..."18:25
nuit123!gq18:25
ubot2`Are you sure your question allows us to help you? Please read http://www.sabi.co.uk/Notes/linuxHelpAsk.html to understand how to ask a 'better' question.18:25
nuit123!poll18:25
ubot2`Usually, there is no single "best" application to perform a given task. It's up to you to choose, depending on your preferences, features you require, and other factors. Do NOT take polls in the channel.18:25
rbasaknuit123: well, the most minimal Ubuntu you can get is Ubuntu Core. https://wiki.ubuntu.com/Core18:26
rbasaknuit123: if you want to go smaller than that, then you could do just a kernel + busybox + whatever you need, but you'd be out of Ubuntu territory then.18:26
rbasakWhichever way you go, you're generally expected to know what you're doing at this level.18:27
nuit123i could use a guiding hand if anyone wishes to helpout.  I'm willing to compensate for a way out of the woods.18:29
rbasakIt sounds too involved for IRC to me. I'd say that you need a consultant or something. But you're welcome to see who else can help you here.18:30
nuit123yes, consultant.18:30
tremnuit123: you want to run a linux on an "embedded board" ? like pandaboard or smaller ?18:34
nuit123whatever is least expensive.  solution only needs to support networking - the same components that are already in Ubuntu Desktop although likely much can be stripped out.18:39
ogra_trem, except that a pandaboard is really way beyond "embedded" :)18:40
tremembedded is not very very clear18:41
ogra_(you can run a full ubuntu desktop on it relatively fluidly)18:41
tremnow, I see embedded board with more ram than my laptop ;)18:41
ogra_well, i wouldnt call something "desktop class" being embedded18:41
tremI agree, that's my question18:42
tremon "small" board, I'll use buildroot + uboot + kernel + busybox18:42
ogra_the beaglebone is sometihing i would call an embedded board18:42
ogra_and the *durino's18:42
nuit123sorry, if i added confusion.  My "breadboard" was Ubuntu and a laptop because it was easy to get my solution working.  Now trying to shrink the software and hardware footprint and cost...18:43
ogra_well, the smallest Ubuntu install that rbasak pointed to above uses something like a 200MB disk footprint ... and there are not even networking pieces installed18:44
tremtoo big18:44
ogra_not sure ubuntu is actually a good choice for "embedded"18:44
tremrasbetty pi should be smaller18:45
tremI agree with ogra_ (again)18:45
* ogra_ disagrees about the RPi being an embedded board though :) 18:45
ogra_its a PVR chip on a board ;)18:45
ogra_(it would be my choice if i wanted to build a video recording box ... for everything else i would choce something else)18:46
ogra_*choose18:46
nuit123Something roughly like this?  http://hardkernel.com/main/products/prdt_info.php?g_code=G13874569627518:47
ogra_wow18:47
ogra_quad core and 2G ram18:47
ogra_well, not actually what i would call embedded ... but you can definitely run an ubuntu rootfs on it18:48
hrwand cheap18:48
hrwand ubuntu can run on it18:48
ogra_right18:48
ogra_you dont want to hook it up to a battery i guess ?18:48
hrwI have wandboard quad at desk. nice it is18:49
ogra_sure sure18:49
ogra_i just expect that people looking for embedded are actually after resource saving somehow :)18:50
tremogra_: RPi is cheap18:51
ogra_trem, yeah, and awful for anything but video decoding18:51
tremeven network ?18:51
ogra_its a USB attached NIC on a shared USB HUB ...18:52
ogra_yes, specifically network18:52
hrwogra_: over shared usb hub connected to otg port18:54
tremarg, not good, ip over usb ...18:54
hrwr/pi is good for....18:55
hrwnothing comes to mind. even not for door stopper or papers holder18:55
tremhttp://liliputing.com/2013/04/99-mars-board-dev-board-features-freescale-i-mx6-dual-processor.html18:56
tremmay be this18:56
hrwtrem: with today's board you can set a list of requirements first and then select boards and start looking for shops18:58
tremyes18:58
hrwsata, 1 or 2 hdmi, usb 2 or 3 and how many18:58
tremthe wandboard seems to be nice18:58
hrwfast of gigabit ethernet18:58
ogra_hrw, if you can live with the blobs RPi is an awesome video decoder18:58
hrwamount of i²c, spi, gpio pins18:58
ogra_the chip was designed to run settop boxes18:59
* hrw off18:59
tremogra_: the wandboard ?18:59
ogra_trem, nope the RPi18:59
tremoh ok18:59
ogra_wandboard is definitely a nice board19:00
tremogra_: and for light embedded linux, buildroot + kernel + busybox ?19:00
ogra_well, for that anything works :)19:01
nuit123ogra and trem, thanks for your helpful comments earlier!20:42

e-RaIs it really a bad idea to install xserver or other window manager on ubuntu server?21:21
infinityCONFIG_ARCH_MXC=y21:43
infinityapplepi: That's on in the Ubuntu config too.  I maintain that you didn't use our congfig. :P21:43
applepibugger...21:43
infinityapplepi: This is our current config http://lucifer.0c3.net/~adconrad/config-3.13.0-17-generic21:43
applepiOkay, that's not what I was pointed to earlier..  let me take a look at this.21:43
infinityapplepi: If what you were pointed at was git, that doesn't really tell the whole sorty, since our config in git are split.21:43
applepiah21:43
applepiyeah that would explain it21:43
infinityapplepi: So, you need to run a script to combine ubuntu.common, armhf.common, armhf.generic, etc...21:43
infinityapplepi: Anyhow, the above that I linked it the finished product, as shipped in the kernel package.21:43
infinityapplepi: And, in fact, no need to build your own kernel, if you want to extract ours from the deb and try it out.21:44
infinityhttps://launchpadlibrarian.net/169034851/linux-image-3.13.0-17-generic_3.13.0-17.37_armhf.deb21:44
infinityThat even includes the imx6q-sabrelite.dtb device-tree, so I expect it's meant to work.21:44
infinityI just need to test it and build d-i for it.21:44
applepiugh, thank you for this..  I am still a bit newbish at this..  I can build my own by trudging through git still loses me sometimes.21:46
infinityapplepi: Yeah, probably not much point in building your own, though, and I'd love ours tested. :P21:46
infinityapplepi: If you need to extract that kernel package to try to get at the image, you can do something like "dpkg-deb -x linux-image-blahblah.deb sometempdir/"21:47
infinityAnd the kernel will be in sometempdir/boot/21:47
infinityAnd the DTB in sometempdir/firmware/$ver/device-tree/21:47
infinityErr, lib/firmware.21:47
infinityAnd the modules in sometempdir/lib/modules/$ver/21:47
