Mar 24 11:35:58 what does this command do " echo 38 > /sys/class/gpio/export "? Mar 24 12:11:57 gives user space access to the gpio Mar 24 12:13:14 http://sites.google.com/site/bifferboard/Home/gpio Mar 24 12:13:55 thank you very much :) Mar 24 12:14:52 there is better docs in the kernel Documentation directory Mar 24 12:15:49 could you suggest any another source/webpage for a beginner to learn more about angstroms dist that I could write a program (in C/c++) for it? Mar 24 12:19:11 most c/c++ stuff applies Mar 24 12:19:34 if you install task-native-sdk, you will have a ciompiler that will wirjk Mar 24 12:19:39 what hw are you using? Mar 24 12:20:15 I have just bought a beaglebone that runs angstroms distrubition Mar 24 12:20:41 it likely alrady has the compiler on it then Mar 24 12:20:48 I am very new on linux environment and embedded programming. Mar 24 12:21:11 for now, pretend it is a disltop machine :) Mar 24 12:21:19 and general linux knowledge will help Mar 24 12:22:16 I saw on angstroms web page there are toolchains for beaglebone Mar 24 12:22:31 http://www.angstrom-distribution.org/toolchains/ Mar 24 12:22:51 have you logged in to the bone yet? Mar 24 12:23:01 yeah Mar 24 12:23:11 I connected to it via ssh Mar 24 12:23:32 I tried to install the toolchain but I could not see it on eclipse or QT SDK Mar 24 12:23:56 the explanation on here http://www.angstrom-distribution.org/toolchains/ is not for noobs I guess :) Mar 24 12:24:44 where do I need to type "$ bitbake meta-toolchain-qte" on beaglebone or host pc (ubuntu)? Mar 24 12:40:32 what tool chain do I need to download for beaglebone http://www.angstrom-distribution.org/toolchains/ ? Mar 24 12:42:56 do I need to install angstrom-2011.03-i686-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.3.tar.bz2 toolchain for beaglebone? Mar 24 16:42:02 hello Mar 24 16:42:06 is there anyone alive? Mar 24 16:42:32 I would like to ask coupe questions about installing angstroms toolchain Mar 24 16:42:42 I would be glad if someone can help me Mar 24 16:46:30 angs: you may be better off asking in #beagle if nobody here can help Mar 24 16:47:46 thanks for the advice, I was asking on beaglebone and never get a reply Mar 24 16:48:30 can I ask a quick question? Mar 24 16:49:25 angs: sure Mar 24 16:49:37 thanks Mar 24 16:49:39 I downloaded angstrom-2011.03-i686-linux-armv7a-linux-gnueabi-toolchain.tar.bz2 on ubuntu Mar 24 16:49:53 I typed the following commands to install the toolchain Mar 24 16:49:59 eagle@ubuntu:~/Desktop$ tar -xf angstrom-2011.03-i686-linux-armv7a-linux-gnueabi-toolchain.tar.bz2 -C /home/eagle/Desktop/s Mar 24 16:50:15 eagle@ubuntu:~/Desktop$ . /home/eagle/Desktop/Toolchain/usr/local/angstrom/arm/environment-setup Mar 24 16:50:34 what do I need to do next? Mar 24 16:50:59 I see different sugestions on some forums, I got confused Mar 24 16:51:05 what to do next Mar 24 16:52:03 what are you trying to do? Mar 24 16:52:38 I am trying to install the cross compiler Mar 24 16:52:58 I have beaglebone and angstrom-2011.03-i686-linux-armv7a-linux-gnueabi-toolchain.tar.bz2 toolchain is suitable for it (I guess) Mar 24 16:53:18 so I downloaded it on ubuntu Mar 24 16:53:29 and installed eclipse on ubuntu Mar 24 16:53:42 right, well by extracting it you've done that... the environment setup script should ensure that when you build something it is cross-compiling rather than using your host compiler Mar 24 16:55:11 so the cross compiler is ready? Mar 24 16:55:23 do I need to do something on eclipse? Mar 24 16:55:57 to define the cross compiler on eclipse? Mar 24 16:56:03 define/add Mar 24 16:57:49 I know almost nothing about eclipse Mar 24 16:58:15 but just running the environment setup script will not be enough since that's just setting up the environment in the shell you ran it from Mar 24 16:58:58 http://www.electronsonradio.com/2011/04/intro-to-basic-cross-compiling-for-the-beagleboard/ I was following the instruction here Mar 24 16:59:16 opkg-target update Mar 24 16:59:16 opkg-target install ncurses Mar 24 16:59:17 opkg-target install ncurses-dev Mar 24 16:59:32 I typed these commands on ubuntu and beaglebone, it did not work Mar 24 16:59:41 I couldnot understand what is the use of it Mar 24 17:00:33 do you know any good instruction for beginners how to install the toolchai Mar 24 17:00:38 *toolchain Mar 24 17:02:14 not really, but that one looks OK to me Mar 24 17:02:54 personally I never use toolchains directly, I use OpenEmbedded (or poky from the Yocto Project) to do all of the cross-compilation for me Mar 24 17:03:51 do you know if I can cross compile a C/C++ code for beaglebone in OpenEmbedded? Mar 24 17:04:27 sure... the easiest thing to do would be to set up an angstrom build environment (which uses openembedded), there are instructions on the angstrom website Mar 24 17:04:43 thank you very much Mar 24 17:05:38 bluelightning, that answer is not going to help him .... Mar 24 17:05:56 Crofton|work: why not? Mar 24 17:06:11 he seems to be a serious beginner Mar 24 17:06:19 more information will be needed, sure... he'll be back Mar 24 17:06:37 are you going to the bsp/collab thing? Mar 24 17:06:45 unfortunately no Mar 24 17:06:48 bummer Mar 24 17:06:56 I'd like to have been there Mar 24 17:07:22 I waited to long to book flights Mar 24 17:07:30 now stuff is nearly full Mar 24 17:07:35 so bad schedules Mar 24 17:07:40 Richard, Tom (Z) and maybe a few others will be there Mar 24 17:07:41 doh Mar 24 17:07:50 there isnt actually chat twice in the same week on Angstrom channel :-D Mar 24 17:07:53 unheard of :-D Mar 24 17:08:07 yeah it's been more active lately I've noticed Mar 24 17:08:43 it got canibalised by #beagle Mar 24 17:08:50 somewhat frustrating that the one person most qualified to answer most questions here is never in this channel... Mar 24 17:09:12 I did try to ask him, but he wasn't interested Mar 24 17:09:33 well, I am not sure he is the best person to answer questions :) Mar 24 17:09:52 who has channel ops here anyway? Mar 24 17:10:00 kergoth I think :-D Mar 24 17:10:23 we all need to get better at answering queations Mar 24 17:10:26 or maybe me :-D Mar 24 17:10:27 I can help sometimes, but it's the "why is it set up this way" questions that are really tough to help with Mar 24 17:10:28 just so many other things going on Mar 24 17:11:26 nope, not me Mar 24 17:12:21 probably kergoth or mickey then Mar 24 17:12:39 Crofton|work: you can try a channel take over I guess Mar 24 21:57:08 I downloaded angstrom-2011.03-i686-linux-armv7a-linux-gnueabi-toolchain.tar.bz2 toolchain for beaglebone. then I typed the following commands on the host pc (ubuntu) Mar 24 21:57:09 tar -xf angstrom-2011.03-i686-linux-armv7a-linux-gnueabi-toolchain.tar.bz2 -C / Mar 24 21:57:09 . /usr/local/angstrom/arm/environment-setup Mar 24 21:57:09 what do I need to do next? Mar 24 21:57:09 I installed eclipse on ubuntu, do I need to do something to add this toolchain on eclipse? Mar 24 23:25:04 what is wrong with it? on what directory do I need to type the command? root@ubuntu:~/Desktop# ./configure --host=arm-angstrom-linux-gnueabi --prefix=/home/vmplanet/gccexamples/nano/nano_out/ Mar 24 23:25:04 bash: ./configure: No such file or directory Mar 25 00:04:57 hmm. built a cloud9-image (or actually something derived from it) and i'm not seeing uboot on the console, just CCCCCC Mar 25 00:06:55 * russell-- has vague sense he's seen someone talking about that same thing, but i'm not finding it now **** ENDING LOGGING AT Sun Mar 25 02:59:58 2012
