**** BEGIN LOGGING AT Tue Aug 23 02:59:56 2011 Aug 23 05:05:20 hi, Aug 23 05:05:38 I wonder if I could get some advice here, regaring Ubuntu on Beagleboard Aug 23 05:05:56 I'm currently running "Robert Nelsons" ubuntu image, and everything seems to work more or less Aug 23 05:06:27 my target is to operate serial infrared trasnceiver on the BB, and for that I chose ubuntu as I saw that lirc was there already in apt Aug 23 05:07:08 however, dpkg-reconfigure complains that it can't compile as I don't have kernel sources installed Aug 23 05:08:59 I don't really know how to compile natively on BB/ubuntu, or how could I cross compile kernel modules on a x86 Aug 23 05:11:11 so I guess I would like to know what someone who understands how these things should be done, suggest to do Aug 23 05:11:54 I tried an official headless image 11.04, but I was unable to get network working on that one (I could not see eth0 nor usb0 at all) Aug 23 05:12:09 it would have enabled me to easily download kernel sources through apt, I guess Aug 23 05:37:39 anyone ? Aug 23 06:08:45 julumme: I think the build-essential package should give you the tools you need to compile things on your BB Aug 23 06:09:10 oh, I see Aug 23 06:09:33 But I don't know where you can get a package with the kernel source for Robert Nelson's kernel Aug 23 06:10:31 there is a link in the Nelson's wiki, where I could get the kernel sources for compiling myself - silly question: so if I git those to my BB, would I then be able to compile lirc against those sourecs ? Aug 23 06:12:34 I guess what I really need, is just the headers and binaries to link against ? Aug 23 06:12:51 sorry for such simple questions, it's all a bit new to me stil Aug 23 06:12:53 I can't see any reason why that wouldn't work.. Aug 23 06:13:48 yeah, check http://www.cyberciti.biz/tips/build-linux-kernel-module-against-installed-kernel-source-tree.html Aug 23 06:14:27 looks interesting, I'll read through, that - thanks Aug 23 06:14:32 I don't know how good the page is, I just googled some. But it looks like it might give you some hints Aug 23 06:18:53 it's all good info, I'm still pretty new to development on linux Aug 23 06:26:03 the info was good indeed Aug 23 06:26:55 erbo, do you happen to know what linux-libc-dev - Linux Kernel Headers for development is ? Aug 23 06:27:38 I'm thinking downloading the whole source code for kernel will take ages ( and also I'm on a budget with space on the BB, as my memory card is currently only 2GB) Aug 23 06:29:23 apt-cache show linux-libc-dev says: "They are NOT meant to be used to build third-party modules for your kernel. Use linux-headers-* packages for that." Aug 23 06:29:31 :p Aug 23 06:30:57 :) Aug 23 06:31:08 ah, linux-headers-omap might be good Aug 23 06:31:54 But I don't know if there's a package with the headers for your custom kernel, those are probably for the ubuntu kernel Aug 23 06:32:08 mmm, I think there is no package Aug 23 06:32:37 my understanding was that Nelson compiled the default kernel for arm, with some settings for BB Aug 23 06:33:16 if that was the case, wouldn't it work if I had same headers ? Aug 23 06:35:06 oh, looks like he used 3.0.0-x2 (?) kernel Aug 23 06:35:30 apt only seems to have 2.6.xx stuff Aug 23 06:35:47 yeah he's using a much never version Aug 23 06:36:31 if you have the source he has used, you can just pass -C /path/to/those/sources when compiling your module Aug 23 06:36:54 hmm, ok, looks like I'll have to get a usb drive or something to pull the sources Aug 23 06:37:00 I'm not sure exactly what you need though Aug 23 06:37:17 he has a git link to the sources Aug 23 06:37:35 I'm hoping to compile lirc against his sources Aug 23 06:37:45 so I could configure to use serial port Aug 23 06:38:06 if your using a usb-stick you can grab the whole git and then you should be ok I think Aug 23 06:38:24 s/your/you're/ :) Aug 23 06:44:19 ok.. let me try that **** BEGIN LOGGING AT Tue Aug 23 09:06:07 2011 Aug 23 11:31:35 hi guys, I'm trying to compile lirc for BB/ubuntu, but I'm running into a strange problem. make fails to before any compiling is done sayng "scripts/genksyms/genksyms: 1: Syntax error: "(" unexpected" Aug 23 11:33:06 there is a pastebin of the whole thing here http://pastebin.com/x2w1VXcP Aug 23 12:11:29 what is the Hardware-accelerated player for ARM Board ? Aug 23 16:37:01 satish_: ??? Aug 23 16:37:05 You mean gstreamer? **** BEGIN LOGGING AT Tue Aug 23 16:51:08 2011 Aug 23 16:57:38 Hi ogra_ Aug 23 16:57:58 Need info regarding USBOTG Aug 23 17:15:16 Anyone farmiliar with using omap kernels and qemu? Aug 23 18:01:30 has ogra_ released an image for the toshiba device? Aug 24 01:32:12 what kind of performance can I expect from OMAP4? Is it capable of running a monitor in fullhd and play movies without problems? Aug 24 01:39:23 jo-erlend: I have seen a single panda play 1080p movies on two screens. Yes it can. Aug 24 01:41:05 wow. Nice. :) Aug 24 01:41:44 GrueMaster, I'm very interested in a pandaboard. How much difficulty will I have installing Ubuntu on it+ Aug 24 01:41:45 ? Aug 24 01:42:26 Not hardly any.. Just follow the info on the wiki (see room topic). Aug 24 01:42:48 and since you seem to have some experience with it... If you should compare it to a PC... What kind of PC would be comparable? Aug 24 01:43:45 Probably an atom based system in overall performance. The only real downside is there isn't a SATA port, so you don't get as good of HD IO performance. Aug 24 01:45:08 The panda is essentially a cell phone development platform, but it can be good for other uses like set top boxes, wifi access point, and even some server tasks. Aug 24 01:47:28 it is a long time since PCs surpassed my needs, so I'm considering replacing my desktop with an ARM board. I was thinking about waiting for the OMAP5, but when I look at the specs for pandaboard, it seems like a potential candidate. Aug 24 01:48:01 the specs doesn't tell me as much though. You can't compare CPU speeds between an x86 and an ARM, right? Aug 24 01:50:02 Not really. Pandas run at something like 1.2Ghz, and on some tasks (like video playback) they are more than sufficient. Other tasks, like heavy duty builds (think rebuild of openoffice) it lacks a lot. Aug 24 01:51:16 sure. But I don't do that. I surf a little bit and I write some python code. That Aug 24 01:51:19 s mostly it. Aug 24 01:51:27 well, except for playing movies and such. Aug 24 01:51:35 And overall cpu speed can be a real misnomer (more of a marketing tool than anything). I spent 8 years at Intel doing processor validation, and back in the day, the mobile processors based on the PIII would outperform the desktop P4 based processors at half the clock rate. Aug 24 01:51:53 the OMAP3 was a little bit too slow and didn't support 1080p, but it seemed very close to acceptable. Aug 24 01:52:12 For the tasks you are looking at, it should be able to handle that fine. Aug 24 01:52:16 GrueMaster, exactly. Aug 24 01:52:21 great :) Aug 24 01:52:54 and the dollar is cheap as well. That's a good bonus. Guess I'll get myself a couple to play with. Aug 24 01:54:45 Heh. I have 6. Aug 24 01:54:55 yes, but you're a pro :) Aug 24 01:55:38 These are personally bought. Only one was provided. But I can write them off at tax time. Aug 24 01:55:39 one thing I thought I could use it for, is to attach it to a VESA wall-mount and connect it to a TV. The HDMI would transmit audio to the TV, right? Aug 24 01:56:08 Yes. Actually, hdmi audio works better sometimes than analog. Aug 24 01:56:54 great. So then I'd install Synergy on it and I could control it with a laptop. That ought to be cool :) Aug 24 01:59:46 wonder if OMAP5 will come with USB3 support. Aug 24 02:00:51 jo-erlend: I'd be surprised. You need a ton of bandwidth... Aug 24 02:02:08 michaelh1, that's probably why I want it :) Aug 24 02:02:32 jo-erlend: yeah, something that isn't USB like SATA would be nice... Aug 24 02:03:09 yes, but is it likely that it'll provide both USB and SATA? Aug 24 02:03:56 other than that, these things seems kinda perfect for a home mikroserver. Aug 24 02:04:55 jo-erlend: SATA seems unlikely on a phone targeted OMAP5. The Samsung Orion has a port though, but I don't know if it works. Aug 24 02:08:44 I'm amazed by how cheap they are. Aug 24 02:10:16 I grew up with 8088 and 8086. Everything is amazing nowadays,, come to think of it :> **** ENDING LOGGING AT Wed Aug 24 02:59:57 2011
