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. [15:24] applepi: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-trusty.git;a=tree;f=debian.master/config;hb=HEAD [15:29] 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? [15:30] I have no idea, sorry. I just happened to have needed to dig into the kernel config before. [15:30] ah okay, thanks. [15:55] anyone here have an mk808 [15:55] or 802 or 802_a10s [18:20] 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? [18:22] !anyone [18:22] 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] :-) [18:25] 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] !details [18:25] 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] !gq [18:25] 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] !poll [18:25] 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. [18:26] nuit123: well, the most minimal Ubuntu you can get is Ubuntu Core. https://wiki.ubuntu.com/Core [18:26] 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. [18:27] Whichever way you go, you're generally expected to know what you're doing at this level. [18:29] i could use a guiding hand if anyone wishes to helpout. I'm willing to compensate for a way out of the woods. [18:30] 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] yes, consultant. [18:34] nuit123: you want to run a linux on an "embedded board" ? like pandaboard or smaller ? [18:39] 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. [18:40] trem, except that a pandaboard is really way beyond "embedded" :) [18:41] embedded is not very very clear [18:41] (you can run a full ubuntu desktop on it relatively fluidly) [18:41] now, I see embedded board with more ram than my laptop ;) [18:41] well, i wouldnt call something "desktop class" being embedded [18:42] I agree, that's my question [18:42] on "small" board, I'll use buildroot + uboot + kernel + busybox [18:42] the beaglebone is sometihing i would call an embedded board [18:42] and the *durino's [18:43] 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... [18:44] 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] too big [18:44] not sure ubuntu is actually a good choice for "embedded" [18:45] rasbetty pi should be smaller [18:45] I agree with ogra_ (again) [18:45] * ogra_ disagrees about the RPi being an embedded board though :) [18:45] its a PVR chip on a board ;) [18:46] (it would be my choice if i wanted to build a video recording box ... for everything else i would choce something else) [18:46] *choose [18:47] Something roughly like this? http://hardkernel.com/main/products/prdt_info.php?g_code=G138745696275 [18:47] wow [18:47] quad core and 2G ram [18:48] well, not actually what i would call embedded ... but you can definitely run an ubuntu rootfs on it [18:48] and cheap [18:48] and ubuntu can run on it [18:48] right [18:48] you dont want to hook it up to a battery i guess ? [18:49] I have wandboard quad at desk. nice it is [18:49] sure sure [18:50] i just expect that people looking for embedded are actually after resource saving somehow :) [18:51] ogra_: RPi is cheap [18:51] trem, yeah, and awful for anything but video decoding [18:51] even network ? [18:52] its a USB attached NIC on a shared USB HUB ... [18:52] yes, specifically network [18:54] ogra_: over shared usb hub connected to otg port [18:54] arg, not good, ip over usb ... [18:55] r/pi is good for.... [18:55] nothing comes to mind. even not for door stopper or papers holder [18:56] http://liliputing.com/2013/04/99-mars-board-dev-board-features-freescale-i-mx6-dual-processor.html [18:56] may be this [18:58] trem: with today's board you can set a list of requirements first and then select boards and start looking for shops [18:58] yes [18:58] sata, 1 or 2 hdmi, usb 2 or 3 and how many [18:58] the wandboard seems to be nice [18:58] fast of gigabit ethernet [18:58] hrw, if you can live with the blobs RPi is an awesome video decoder [18:58] amount of i²c, spi, gpio pins [18:59] the chip was designed to run settop boxes [18:59] * hrw off [18:59] ogra_: the wandboard ? [18:59] trem, nope the RPi [18:59] oh ok [19:00] wandboard is definitely a nice board [19:00] ogra_: and for light embedded linux, buildroot + kernel + busybox ? [19:01] well, for that anything works :) [20:42] ogra and trem, thanks for your helpful comments earlier! === Valduare_ is now known as Valduare === TheMuso` is now known as TheMuso === Valduare_ is now known as Valduare [21:21] Is it really a bad idea to install xserver or other window manager on ubuntu server? [21:43] CONFIG_ARCH_MXC=y [21:43] applepi: That's on in the Ubuntu config too. I maintain that you didn't use our congfig. :P [21:43] bugger... [21:43] applepi: This is our current config http://lucifer.0c3.net/~adconrad/config-3.13.0-17-generic [21:43] Okay, that's not what I was pointed to earlier.. let me take a look at this. [21:43] 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] ah [21:43] yeah that would explain it [21:43] applepi: So, you need to run a script to combine ubuntu.common, armhf.common, armhf.generic, etc... [21:43] applepi: Anyhow, the above that I linked it the finished product, as shipped in the kernel package. [21:44] 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] https://launchpadlibrarian.net/169034851/linux-image-3.13.0-17-generic_3.13.0-17.37_armhf.deb [21:44] That even includes the imx6q-sabrelite.dtb device-tree, so I expect it's meant to work. [21:44] I just need to test it and build d-i for it. [21:46] 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] applepi: Yeah, probably not much point in building your own, though, and I'd love ours tested. :P [21:47] 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] And the kernel will be in sometempdir/boot/ [21:47] And the DTB in sometempdir/firmware/$ver/device-tree/ [21:47] Err, lib/firmware. [21:47] And the modules in sometempdir/lib/modules/$ver/ === ojn_ is now known as ojn
