**** BEGIN LOGGING AT Fri Dec 20 03:00:00 2013 Dec 20 03:15:00 So, I have this issue with my BBB. I am running Angstrom and I have followed the instructions on elinux.org to use the SD card for extra storage. However, I am having trouble with the permissions. I don't have execute permission, despite using chmod, in "su" and "su -" mode Dec 20 03:16:25 I have created the uEnv.txt file on the SD card. One of the lines says: "mmcroot=/dev/mmcblk1p2 ro" Does the "ro" have anything to do with it? Dec 20 03:20:46 The current mounting location is "/media/6A3F-B5B6", should I just mount it on a different location? where is the mount command executed at boot and how come it does not include full permissions? Dec 20 05:43:24 User45548: the execute permissions fo rwhat? Dec 20 05:43:53 User45548: the ro in the kernel command line is only for the initial mounting of the root fs. most systems remount rw later during the boot process Dec 20 05:44:52 hii.... i need some suggestion.... Dec 20 05:45:13 I am trying to build a quadcopter using beaglebone black.... Dec 20 05:46:31 And I am not sure how do i control beaglebone from my android phone via wifi.... I cant find any tutorials for the same yet.... can anyone suggest me something??? Dec 20 05:51:20 Yeah, write the software to do it. Dec 20 05:51:36 The bone runs Linux. Standard Linux development systems apply. Dec 20 05:55:17 Yes, I will be writing code in c++/python.... Havent decided yet... I am planning to do full controlling from beaglebone rather than using a adruino or any microcontroller as slave to control the ESC's and sensors.... I am newbie in this.... I dont know if this is the right place to ask, is it possible to do so...?? Dec 20 05:56:39 read the stevens book Dec 20 06:00:34 I have Matt Richardson's book "Getting Started with BeagleBone" .... Dec 20 06:00:56 Is stevens book good?? Dec 20 06:07:03 for networking, yes Dec 20 06:07:38 thanks ds2 ...:) let me check it out.... I will post here if i have any doubt Dec 20 06:07:45 :D Dec 20 06:13:50 Razor_Kickass: most Unix/Linux programming books will apply Dec 20 06:14:15 this is the beauty of the bone... develop apps on desktops, recompile and it runs on the bone Dec 20 06:17:54 Hello KotH, I am trying to build ffmpeg from the source. I would like to keep the files on the SD card. But I am getting "permission denied" erros Dec 20 06:18:32 I have looked up a few things and people say that chmod will not work, as the permissions are set when I mount the sd card Dec 20 06:19:56 I have tried to manually mount the SD card to a folder I created with fmask=0022 and it did not help Dec 20 06:20:25 The reason why I am trying to build the files on the SD card is that I am running out of space on the 2Gb on-board storage Dec 20 06:23:38 what are you mounting? Dec 20 06:24:03 if you are mounting a FAT (or FAT related FS), there are no perms... the permissions are an illusion Dec 20 06:24:19 the mount point's permission has no effect whatsoever Dec 20 06:25:01 I am mounting /dev/mmcblk0p1 Dec 20 06:26:15 Hi Dec 20 06:26:59 pastebin.com the output of "mount" Dec 20 06:27:19 The command that I am using is (as root): mount -t vfat -o rw, auto,user, fmask=0022, dmask=0000 /dev/mmcblk0p1 /mnt/sd Dec 20 06:27:35 it will take me a few seconds to get the pastebin Dec 20 06:27:42 its ok Dec 20 06:27:54 what does fmask 0022 do? Dec 20 06:32:31 should it be umask? Dec 20 06:34:46 I assume that the output of mount should be with the "-v" option. The only output I get is "mount: /dev/mmcblk0p1 mounted on /mnt/sd" Dec 20 06:46:31 I tried it with umask and I still don't have permission to execute files Dec 20 06:59:30 https://www.google.com/search?q=mount+fat32+executable Dec 20 07:00:42 Thank you av500 I will take a look Dec 20 07:48:26 Hi...Csn we use the same uSD card in Beaglebone white to write the image in Beaglebone black... Dec 20 09:13:52 beagle13: you can even use your pc. but you need to know what you are doing Dec 20 09:23:23 hello Dec 20 09:23:54 I would like to run beaglebone blac image under qemu Dec 20 09:24:03 Is there someone to help me with it ? Dec 20 09:25:18 user__: this is not supported so far, at least not with the beaglebone blacks kernel and peripherals. Dec 20 09:25:49 ok Dec 20 09:26:14 user__: you should be able to create a qemu-fitting armv7-kernel, then you can maybe use the beagles userland for simple experimentation Dec 20 09:27:19 I need to compile kernel for xenomai Dec 20 09:27:36 I was able to do this using RobertCNelson repo Dec 20 09:27:56 however it didn't compile tools for kernel with cross-compilation Dec 20 09:28:11 I need those to build RTnet on BBB Dec 20 09:32:48 xenomai+qemu+beagle is not likely to work, at least not out of the box. Dec 20 09:33:33 ok, could you tell me how can I cross-compile kernel tools Dec 20 09:33:52 i have no idea what you mean by that. Dec 20 09:36:05 in kernel sources there are tools directory and anything what is there is not cross-compiled during kernel build Dec 20 09:36:18 well then find the target and kick it off. Dec 20 09:36:33 probably "make tools" or such, i've never needed that so far. Dec 20 09:37:10 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/tools/Makefile Dec 20 09:38:05 ok, but I don't want to compile it on BBB, I want to cross-compile whole kernel Dec 20 09:38:39 use the same cross compilation flags like you would for the kernel, just give that targets instead of uImage or such. Dec 20 09:39:08 CROSS_COMPILE= ARCH=arm make Dec 20 09:39:36 Thank you, I'll check it Dec 20 09:40:12 i suggest you actually learn to build the kernel manually with out tricks/scripts first before trying to do yenomai magic or such. Dec 20 09:41:19 I'm using RobertCNelson's script which do all the magick in the world but the problem is with the tools only Dec 20 09:43:26 no the problem is not the kernel tools, the problem is that you do not know/understand what the script does. Dec 20 09:43:59 i guess it can also build the tools, its just another make target. Dec 20 09:45:37 Yes' Ive just edited the script for building the kernel. I've added tools target and we will see what happens Dec 20 10:35:42 hi again Dec 20 10:35:55 this is my command line: Dec 20 10:35:59 make -j${CORES} ARCH=arm LOCALVERSION=-${BUILD} CROSS_COMPILE="${CC}" zImage modules tools scripts Dec 20 10:36:37 after that tools like fixdep and modpos are compiled as x86 not as arm target Dec 20 10:37:41 so after installation this on BBB a can't build kernel modules because of this inaproperiate architecture Dec 20 10:49:13 * KotH nods Dec 20 10:49:24 the architecture was truly inapropriate Dec 20 12:21:29 * aurelien receive the BBB \o/ Dec 20 12:21:45 * aurelien is away 15 days in south of France ... Mery Christmas Beagle! Dec 20 12:33:11 woooo! bbb is here Dec 20 12:33:23 can I do anything with it just over usb? Dec 20 12:33:36 (on linux) Dec 20 12:45:23 hi, can anyone recommend a screen for BBB that has drivers etc, over 3.2" preferably 4.3" and thats not a CAPE? Dec 20 13:05:19 take a cape Dec 20 13:05:22 solder long wires Dec 20 13:05:24 done Dec 20 13:54:36 av500: is the bbb armv7? Dec 20 13:54:43 yes Dec 20 13:54:50 thanks Dec 20 13:54:58 * flughafen is setting up cross compilation junk Dec 20 14:41:18 I have a BBB A5C that has been running the Asterisk distro RASPBX. I locked myself out of SSH on ETH0. Since I didn't have a 5v power suppy, I was powering it through the mini-usb but it wasn't connected to a computer. I was forced to remove power to get it off the high shelf. Since that time, the power light comes on but nothing else happens. Trying SDcard didn't help. I'm ready to RMA but thought I'd check for ideas. Any tho Dec 20 15:17:23 i am new to using beagle bone black Dec 20 15:17:33 i had this single query Dec 20 15:17:45 i intend to setup 2 screens to my bbb Dec 20 15:18:21 the 4DCAPE-70T supports additional capes via the additional headers, can another display cape be setup? Dec 20 15:41:37 qeuestion about the "gadget" framework, is this just a driver now in the kernel? if so what is it called? for the networking over usb(on linux)? Dec 20 17:55:05 hey jkridner... are you buried in the white stuff yet? Dec 20 17:55:24 not so much. rain today. :( Dec 20 17:55:34 there's about 6" on the ground still, but melting away. :( Dec 20 17:56:39 guess the reports are exaggerated about the northeast Dec 20 17:57:24 you'd probably call me more midwest Dec 20 17:57:30 even if Eastern time zone Dec 20 17:58:08 oh Dec 20 18:41:31 Entirely new to IRC and beaglebone black, trying to get bluetooth working with a2dp similar to these guides: http://www.instructables.com/id/Turn-your-Raspberry-Pi-into-a-Portable-Bluetooth-A/?ALLSTEPS and http://kmonkey711.blogspot.com/2012/12/a2dp-audio-on-raspberry-pi.html but running into lots of trouble going between angstrom on the beaglebone black and wheezy on the rasppi Dec 20 18:55:41 pbar: you could try one of the debian-based bbb images Dec 20 19:32:16 anybody tested http://www.exploitsys.com/ENG/GPRS%20BB%20Cape.html ? Dec 20 19:32:45 some info how good the GSM module is ? and especially if you can pipe voice into a GSM call. Dec 20 19:36:55 Hi does anybody know how to make the beaglebone black work with the motorola atrix lapdock? when I connect everything I've got a banner for a couple of seconds and nothing after that. Dec 20 22:08:47 hi, short question, though about using openbsd on one of this box... which one should I pick ? (beagle black board) ?... any input welcome Dec 20 22:09:59 short question 2, if you need more than 1 ethernet interface, would you use ethernet usb devices or other suggestions are welcome too :) Dec 20 22:10:31 btw good/cool/great job realising these devices Dec 20 22:10:36 =) Dec 20 22:26:44 well (pm) if you have any input Dec 20 22:26:56 congrats for the great job again Dec 20 23:14:29 Anyone here have experience writting bitbake receipes for cross-compiling normal linux projects? Dec 20 23:19:05 dgilmore, there should be lots of recipes already that do exactly that Dec 20 23:21:45 Sure, which I am trying to follow, but I am a little fuzzy about what parameters to pass to configure. Dec 20 23:22:02 ...using BitBake variables, that is. Dec 20 23:23:17 When trying to link the shared library at the end of the compilation, gcc is using /usr/lib instead of a cross-compile equivelent. Dec 20 23:23:58 Conceptually, I realize that I need to tell configure some more info, but I don't know the specifics. **** ENDING LOGGING AT Sat Dec 21 02:59:59 2013
