| applepi | Can 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 |
|---|---|---|
| rbasak | applepi: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-trusty.git;a=tree;f=debian.master/config;hb=HEAD | 15:24 |
| applepi | rbasak: 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 |
| rbasak | I have no idea, sorry. I just happened to have needed to dig into the kernel config before. | 15:30 |
| applepi | ah okay, thanks. | 15:30 |
| Valduare | anyone here have an mk808 | 15:55 |
| Valduare | or 802 or 802_a10s | 15:55 |
| nuit123 | I'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 | !anyone | 18:22 |
| 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 |
| nuit123 | i'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 | !details | 18:25 |
| 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 | !gq | 18:25 |
| 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 | !poll | 18:25 |
| 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 |
| rbasak | nuit123: well, the most minimal Ubuntu you can get is Ubuntu Core. https://wiki.ubuntu.com/Core | 18:26 |
| rbasak | nuit123: 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 |
| rbasak | Whichever way you go, you're generally expected to know what you're doing at this level. | 18:27 |
| nuit123 | i could use a guiding hand if anyone wishes to helpout. I'm willing to compensate for a way out of the woods. | 18:29 |
| rbasak | It 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 |
| nuit123 | yes, consultant. | 18:30 |
| trem | nuit123: you want to run a linux on an "embedded board" ? like pandaboard or smaller ? | 18:34 |
| nuit123 | whatever 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 |
| trem | embedded is not very very clear | 18:41 |
| ogra_ | (you can run a full ubuntu desktop on it relatively fluidly) | 18:41 |
| trem | now, I see embedded board with more ram than my laptop ;) | 18:41 |
| ogra_ | well, i wouldnt call something "desktop class" being embedded | 18:41 |
| trem | I agree, that's my question | 18:42 |
| trem | on "small" board, I'll use buildroot + uboot + kernel + busybox | 18:42 |
| ogra_ | the beaglebone is sometihing i would call an embedded board | 18:42 |
| ogra_ | and the *durino's | 18:42 |
| nuit123 | sorry, 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 installed | 18:44 |
| trem | too big | 18:44 |
| ogra_ | not sure ubuntu is actually a good choice for "embedded" | 18:44 |
| trem | rasbetty pi should be smaller | 18:45 |
| trem | I 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_ | *choose | 18:46 |
| nuit123 | Something roughly like this? http://hardkernel.com/main/products/prdt_info.php?g_code=G138745696275 | 18:47 |
| ogra_ | wow | 18:47 |
| ogra_ | quad core and 2G ram | 18:47 |
| ogra_ | well, not actually what i would call embedded ... but you can definitely run an ubuntu rootfs on it | 18:48 |
| hrw | and cheap | 18:48 |
| hrw | and ubuntu can run on it | 18:48 |
| ogra_ | right | 18:48 |
| ogra_ | you dont want to hook it up to a battery i guess ? | 18:48 |
| hrw | I have wandboard quad at desk. nice it is | 18:49 |
| ogra_ | sure sure | 18:49 |
| ogra_ | i just expect that people looking for embedded are actually after resource saving somehow :) | 18:50 |
| trem | ogra_: RPi is cheap | 18:51 |
| ogra_ | trem, yeah, and awful for anything but video decoding | 18:51 |
| trem | even network ? | 18:51 |
| ogra_ | its a USB attached NIC on a shared USB HUB ... | 18:52 |
| ogra_ | yes, specifically network | 18:52 |
| hrw | ogra_: over shared usb hub connected to otg port | 18:54 |
| trem | arg, not good, ip over usb ... | 18:54 |
| hrw | r/pi is good for.... | 18:55 |
| hrw | nothing comes to mind. even not for door stopper or papers holder | 18:55 |
| trem | http://liliputing.com/2013/04/99-mars-board-dev-board-features-freescale-i-mx6-dual-processor.html | 18:56 |
| trem | may be this | 18:56 |
| hrw | trem: with today's board you can set a list of requirements first and then select boards and start looking for shops | 18:58 |
| trem | yes | 18:58 |
| hrw | sata, 1 or 2 hdmi, usb 2 or 3 and how many | 18:58 |
| trem | the wandboard seems to be nice | 18:58 |
| hrw | fast of gigabit ethernet | 18:58 |
| ogra_ | hrw, if you can live with the blobs RPi is an awesome video decoder | 18:58 |
| hrw | amount of i²c, spi, gpio pins | 18:58 |
| ogra_ | the chip was designed to run settop boxes | 18:59 |
| * hrw off | 18:59 | |
| trem | ogra_: the wandboard ? | 18:59 |
| ogra_ | trem, nope the RPi | 18:59 |
| trem | oh ok | 18:59 |
| ogra_ | wandboard is definitely a nice board | 19:00 |
| trem | ogra_: and for light embedded linux, buildroot + kernel + busybox ? | 19:00 |
| ogra_ | well, for that anything works :) | 19:01 |
| nuit123 | ogra and trem, thanks for your helpful comments earlier! | 20:42 |

| e-Ra | Is it really a bad idea to install xserver or other window manager on ubuntu server? | 21:21 |
| infinity | CONFIG_ARCH_MXC=y | 21:43 |
| infinity | applepi: That's on in the Ubuntu config too. I maintain that you didn't use our congfig. :P | 21:43 |
| applepi | bugger... | 21:43 |
| infinity | applepi: This is our current config http://lucifer.0c3.net/~adconrad/config-3.13.0-17-generic | 21:43 |
| applepi | Okay, that's not what I was pointed to earlier.. let me take a look at this. | 21:43 |
| infinity | applepi: 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 |
| applepi | ah | 21:43 |
| applepi | yeah that would explain it | 21:43 |
| infinity | applepi: So, you need to run a script to combine ubuntu.common, armhf.common, armhf.generic, etc... | 21:43 |
| infinity | applepi: Anyhow, the above that I linked it the finished product, as shipped in the kernel package. | 21:43 |
| infinity | applepi: 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 |
| infinity | https://launchpadlibrarian.net/169034851/linux-image-3.13.0-17-generic_3.13.0-17.37_armhf.deb | 21:44 |
| infinity | That even includes the imx6q-sabrelite.dtb device-tree, so I expect it's meant to work. | 21:44 |
| infinity | I just need to test it and build d-i for it. | 21:44 |
| applepi | ugh, 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 |
| infinity | applepi: Yeah, probably not much point in building your own, though, and I'd love ours tested. :P | 21:46 |
| infinity | applepi: 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 |
| infinity | And the kernel will be in sometempdir/boot/ | 21:47 |
| infinity | And the DTB in sometempdir/firmware/$ver/device-tree/ | 21:47 |
| infinity | Err, lib/firmware. | 21:47 |
| infinity | And the modules in sometempdir/lib/modules/$ver/ | 21:47 |
