**** BEGIN LOGGING AT Thu Jul 03 03:00:01 2014 Jul 03 03:53:50 pdp7: I was just working on a kernel patches to add another set of eqep overlays that only mux the A and B inputs, and I noticed that the eqep2b overlay isn't in linux-dev yet. You wouldn't happen to know if that's been sent to rcn-ee yet would you? Jul 03 04:13:50 Hello everyone. Would anyone be able to help with a question regarding the Beaglebone Black on Ubuntu? Jul 03 04:14:48 In terminal, I was under the BBB boot/uboot/LEDscape directory, and when I rm'ed a file the entire BBB turned into read-only. Is there a way to reverse the read-only status? Jul 03 04:42:02 Hi beagle.. Jul 03 04:43:51 Any body is there.. Jul 03 04:44:37 if you've got a question, go ahead and ask it, and wait patiently for a response Jul 03 04:45:40 ok...thank you. Jul 03 04:53:19 I am trying to bring up the beaglebone black board using yocto. So that i cloned meta-beagleboard and meta-oe for minimal compilation using core-image-minimal . if i try to boot the board i am getting web link mentioned error http://pastebin.com/cxjFjC18 Jul 03 04:54:24 please some one help me to solve this issue.Because of this i am struggling a lot. Jul 03 04:54:42 it's very urgent project for me...please Jul 03 04:55:10 remember that part about patience? Jul 03 05:45:55 Hello everyone! I'm exploring TTL serial cables for BBB. I've 3 choices but I'm not sure if they will work with a BBB and whether they're good stuff. http://www.protocentral.com/raspberry-pi/220-usb-to-ttl-serial-cable-debug-console-cable-for-raspberry-pi.html vs http://www.embeddedmarket.com/products/USB-to-Serial-TTL-3-3V-Cable-For-Olimex-Single-board-Linux-computer/ vs http://hacktronics.co.in/home/168-rs232-to-ttl-module-with-transceiver-indicator. Jul 03 05:45:55 html. Could someone help out here? Jul 03 05:46:11 make sure it's 3.3V Jul 03 05:47:05 the USB to TTL ones(first two) are solely 3.3V. The RS232 to TTL one is configurable - 3.3V/5V. Jul 03 05:51:37 anything that can do 3.3V will do Jul 03 05:53:55 Ah I see. So the 'for raspberry pi' and 'for olimex...' can be ignored safely. That's good to know :). Jul 03 05:54:22 All I need to keep in mind is the RX/TX output should be 3.3V or bye bye BBB :). Thanks tbr! Jul 03 06:42:18 please support me..i am struggling a lot. Jul 03 06:42:31 support you in what? Jul 03 06:42:51 I am trying to bring up the beaglebone black board using yocto. So that i cloned meta-beagleboard and meta-oe for minimal compilation using core-image-minimal . if i try to boot the board i am getting web link mentioned error http://pastebin.com/cxjFjC18 Jul 03 06:43:36 elinuxer: you do not have the device tree in place i think so Jul 03 06:43:48 it needs to be appended to the kernel image Jul 03 06:50:09 vvu:i am yocto toolchain so compiled minimal image,after compilation i got image ..........please check in link. http://pastebin.com/FicEU57f Jul 03 06:50:32 elinuxer: i will support you. here is stick Jul 03 06:53:30 i am trying to boot with MLO,u-boot.img,uImage-beaglebone.bin from my compiled image. Jul 03 06:55:34 i think..i have to add or modify according to machine in bootloader or kernel but i don't get clear idea. Jul 03 06:55:58 elinuxer where does it stuck? Jul 03 06:56:44 please check this link http://pastebin.com/cxjFjC18 Jul 03 06:59:41 elinuxer: repeating the same question 3 times does not speak well of your mental health Jul 03 07:02:03 solution to bring up the board please.. Jul 03 07:02:17 and your attitude won't work here. full stop. Jul 03 07:03:05 Error: unrecognized/unsupported machine ID (r1 = 0x00000e05). Jul 03 07:03:08 really clear Jul 03 07:03:19 now its on to you to fix it Jul 03 07:04:28 i am really clear..that's problem. Jul 03 07:05:29 and there are plenty of solutions, if you would use the internet search engine of your least distrust Jul 03 07:17:59 please give me any one link.. Jul 03 07:20:27 http://bit.ly/1qpqj00 Jul 03 07:31:54 helllo and good morning. I have removed armstrong to work with debian. but it does something really funny. after installing lighttpd on my bbb and then try to redirect to the ip of the ehternet it gets it sends me to the BBB startup to show me that the device is working insteed of the placeholder of lighttpd index. Jul 03 07:32:01 any ideas? Jul 03 07:35:52 it means that you didn't disable those services in systemd Jul 03 07:36:06 also by default it runs an apache2 on port 8080 or 8000 Jul 03 07:36:36 i disabled them right now Jul 03 07:36:46 and now it runs nothing =/ Jul 03 07:37:11 also I have removed apache2 from the system Jul 03 07:38:37 ps -aux should tell you what is running Jul 03 07:40:38 okay I have killed all lighttpd proccess , I will try to reboot the config file and lighttpd Jul 03 07:43:48 still the same thing , now it just open nothing it gives me problem loading the page Jul 03 07:55:40 hello beagle already i have searched all the related search for few days. If you see all the compilation has done separately in the related links no one has done yocto so they can compile and dtb file. but i am trying in yocto with meta-beagleboard and meta-oe layer... Jul 03 07:57:05 there is a #yocto channel Jul 03 07:57:10 my doubt here is i am using default configuration given meta-beagleboard/commom-bsp/ layers for kernel and u-boot. Jul 03 07:57:19 sorry, no meta-idea about that Jul 03 07:58:40 i understand...how can i ask machine related issues in yocto.. Jul 03 07:59:06 you write a question Jul 03 07:59:13 and put a "?" at the end Jul 03 07:59:20 no? Jul 03 08:01:21 ok..thanks for your humble response... Jul 03 08:01:39 well, I dont know what to tell you Jul 03 08:01:52 beagleboard.org supports angstrom and debian Jul 03 08:02:00 tell him to buy chocolate? chocolate always helps! Jul 03 08:02:07 yes Jul 03 08:02:20 few people here run yocto Jul 03 08:02:55 so why run yocto? Jul 03 08:45:48 How do I disable a flash card from automatic starting to flash my embedded flash (debian) Jul 03 08:46:31 use a non-flashing image Jul 03 08:46:59 Hello everyone! I'm using a PL2303 USB to TTL converter to connect to BBB's serial pins. When I connect to /dev/ttyUSB0 using screen at baud rate 11520, I don't see any output at all. Is there no output on serial from power on? Jul 03 08:47:18 115200 Jul 03 08:47:28 there is serial output Jul 03 08:48:50 how do i know the difference? Jul 03 08:48:56 where can I find it. Jul 03 08:49:25 http://beagleboard.org/latest-images/ Jul 03 08:49:54 which is btw a link from the homepage Jul 03 08:49:58 thanks jkridner!!!! Jul 03 08:50:09 Hmmm right the baud rate missed a 0. I tried using minicom(115200 8N1) and it says "Offline". Jul 03 08:50:17 ignore the offline Jul 03 08:50:21 its not a phone modem Jul 03 08:50:31 no dial tone Jul 03 08:51:30 Ah okay. I press enter key but don't get a prompt(well nothing happens in minicom). I can login via SSH fine. Jul 03 09:05:20 Is there some technical software documention avaible Jul 03 09:13:51 yes Jul 03 09:13:57 beagleboard.org Jul 03 09:18:13 ok where is the boot process described. Jul 03 09:20:02 I like to know why my flash card start flashing. Because it is very annoying my data is destroyed every time Jul 03 09:23:31 use a non-flashing image Jul 03 09:23:36 [10:52] http://beagleboard.org/latest-images/ Jul 03 09:28:45 yes. But how do i know it is non-flashing image!! Jul 03 09:30:07 I like to know how it works. Jul 03 09:32:45 av500, any chance to get a flashing jessie image ? Jul 03 09:33:13 av500, I got one on sd card, but when it boots its altering what I have saved on it.. Jul 03 09:37:33 I also like a jessie image because i need libc-2.15 Jul 03 09:41:00 evs, I need gcc 4.8 Jul 03 09:42:53 I need cows flying Jul 03 09:43:23 there are drugs for that :-) Jul 03 09:43:23 woglinde, if you can't say anything that makes sense, just dont Jul 03 09:44:04 evs, maybe he needs stronger ones ;) Jul 03 09:53:13 mkad: I have no idea Jul 03 09:53:22 there are debian images on beagleboard.org Jul 03 09:53:43 I understand one can update SW on debian with newer versions Jul 03 09:58:36 av500 apt-get is to hard to use Jul 03 10:12:57 * ogra_ wonders what woglinde wants to do with the flying cows ... Jul 03 10:13:01 milky rain ? Jul 03 11:01:59 ping mrpackethead if you're still awake :D Jul 03 11:02:14 HI Jul 03 11:02:24 only just Jul 03 11:02:28 steev: Jul 03 11:02:34 stt_michael: hello Jul 03 11:03:04 can you pm your email again :) Jul 03 11:10:10 woglinde, yes it's hard, because as you might ever actually upgraded upgraded distribution, things can break, for example node-js previously working on wheezy, after upgrade fails on jessie. But yeah, having thought about it requires higher brain activity, so I cant help you. Also you cant help me, so please stop commenting my questions, if you cannot help and only you do, is behaving rude. Jul 03 11:11:09 mkad I never saw you here and you starting getting aggressive Jul 03 11:11:20 woglinde, be careful else you get your butt slapped ;) Jul 03 11:11:25 because you can solve the problems your self Jul 03 11:11:34 can not Jul 03 11:11:52 and no one said node-js should run after an upgrade Jul 03 11:12:08 mkad, what makes you think node.js would behave any better on a freshly installed jessie ? Jul 03 11:12:36 besides no one said node-js must run at all Jul 03 11:12:40 (it would be the same package as if you upgrade ... ) Jul 03 11:12:50 that too Jul 03 11:13:02 woglinde, please I dont need your outsmarted ideas ok? Jul 03 11:13:27 mkad please leave the channel if you have problems Jul 03 11:13:40 yeah, attacking people isnt helpful at all Jul 03 11:13:44 woglinde, I am just asking you to stop talking/responding to me, thats it, Jul 03 11:14:01 ogra_, he attacked me, with stupid comments, that are not helpful at all Jul 03 11:14:11 I attacked nobody Jul 03 11:14:54 he didnt ... Jul 03 11:14:56 ok guys, calm down Jul 03 11:15:00 I am calm Jul 03 11:15:02 ogra_, "its hard to use apt-get" is rude Jul 03 11:15:04 * ogra_ too Jul 03 11:15:12 mkad, is it ? Jul 03 11:15:14 ogra_, I know what tool does, and I did that Jul 03 11:15:32 well, then you are fine, no ? Jul 03 11:15:37 ogra_, yeah its like I saw just fucking google it, or I provide you with the damn stupid simple solution and I show off how smarter I am Jul 03 11:16:08 ogra_, showing off how smarter one is and provided trivial solutions is not helping but is rude Jul 03 11:16:22 ogra_, no upgrading didn't help, since lots of things broke Jul 03 11:16:39 I was more curious if there is a image that has a quality of wheezy image Jul 03 11:16:51 such that things are tested/fixed Jul 03 11:16:54 well, usually debian upgrades done break Jul 03 11:16:57 if not fine... Jul 03 11:16:58 *dont Jul 03 11:17:18 mkad: there is no image that I know of Jul 03 11:17:44 av500, thanks, thats end of my question:) sorry that I got angry Jul 03 11:22:16 apt-get install aptitude Jul 03 11:22:24 why the hell the tools are separate I dunno lol Jul 03 11:22:37 anyway .. go on .. :D Jul 03 11:23:12 stt_michael, aptitude I think was a replacement for apt, but people still use apt-get... Jul 03 11:23:34 stt_michael, and I think something went wrong with configuration files in the new package, not dependencies.. Jul 03 11:23:42 anyway nevermind Jul 03 12:30:29 hey guys, I'm having prblems with my TRC chip (ds1307). It is detected on i2c bus, I can activate it, but hwclock -r ode -w gives only error message Jul 03 12:30:46 sorry, I meant RTC chip Jul 03 12:31:22 hwclock -r -f /dev/rtc1 Jul 03 12:31:23 hwclock: Timed out waiting for time change. Jul 03 12:31:47 BennyB_, did you try i2cdetect ? Jul 03 12:32:13 BennyB_, I am playing with other chip, and I used i2cdetect -y -r 1 to see if I can find it on the bus Jul 03 12:32:55 BennyB_, than you can use i2cget 1 chipaddr regaddr to query it Jul 03 12:33:01 afaik Jul 03 12:33:04 yup, it's all fine. the device was detected on address 67, and after I echoed to i2c-1/new_device the device is use Jul 03 12:33:14 ok, I'll try Jul 03 12:33:33 BennyB_, my device returns it's id when i query whoami reg with i2cget Jul 03 12:33:54 BennyB_, to me that's the confirmation that hardware works Jul 03 12:35:51 mkad canu you write the i2c command more detailed? "i2cget 1 68" tells me read failed Jul 03 12:36:15 makad I used this command to activate: "echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device" Jul 03 12:36:41 BennyB_, I dont have BBB with me now Jul 03 12:36:44 what does whoami with i2c to do? Jul 03 12:37:19 well datasheet of my chip says that 0x20 is the whoami reg which reading should return addr of the chip 0xb2 Jul 03 12:37:33 write addr Jul 03 12:37:47 check datasheet for your chip Jul 03 12:38:18 I followed the guide on https://learn.adafruit.com/adding-a-real-time-clock-to-beaglebone-black?view=all which worked like a charm on angstrom, but now I'm on wheezy Jul 03 12:39:55 oh maybe your chip does not have that Jul 03 12:39:59 whoami Jul 03 12:40:24 maybee, I didn't even know that chips can have a whoami command.. Jul 03 12:40:49 I only know whoami bash command Jul 03 12:41:24 http://www.maximintegrated.com/en/images/appnotes/100/app100-3.gif Jul 03 12:41:29 this seems like the register map Jul 03 12:41:59 so you should do i2cget 1 0x68 0xC0 Jul 03 12:42:03 to read status register Jul 03 12:42:12 ok, I try Jul 03 12:42:28 I dont remember now from the top of my head it is Jul 03 12:42:33 Error: Could not set address to 0x68: Device or resource busy Jul 03 12:42:38 thats the answer Jul 03 12:42:43 busy Jul 03 12:43:07 well then Jul 03 12:43:50 maybe try lsof | grep /dev/i2c-1 Jul 03 12:43:54 i make a clean boot and try again Jul 03 12:44:22 mybe that can show what is using it Jul 03 12:44:38 k have fun:) Jul 03 12:45:08 hm, lsof is not installed... apt-getting it... Jul 03 12:45:49 BennyB_, dunno if that can show process using device.. but there should be a tool on gnu/linux to do that, and out of curiosity I would check that route before rebooting ;) Jul 03 12:46:05 ok, the command returns nothing Jul 03 12:46:13 as root? Jul 03 12:46:36 yes, Iv ssh'ed as root the my bbb Jul 03 12:47:33 dunno google also says lsof Jul 03 12:48:32 lsof /dev/i2c-1 returns also nothing Jul 03 12:49:08 i2cdetect -y -r 1 says: Jul 03 12:49:11 0 1 2 3 4 5 6 7 8 9 a b c d e f Jul 03 12:49:13 00: -- -- -- -- -- -- -- -- -- -- -- -- -- Jul 03 12:49:14 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Jul 03 12:49:16 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Jul 03 12:49:17 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Jul 03 12:49:19 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Jul 03 12:49:20 50: -- -- -- -- UU UU UU UU -- -- -- -- -- -- -- -- Jul 03 12:49:22 60: -- -- -- -- -- -- -- -- UU -- -- -- -- -- -- -- Jul 03 12:49:36 before the echo command there was an "68" Jul 03 12:49:36 dont paste so much use pastebin Jul 03 12:49:49 ok, mexyt time Jul 03 12:50:04 well it disapear Jul 03 12:50:15 its a hardware problem / wiring than Jul 03 12:50:29 or maybe pull-up? Jul 03 12:50:30 it changed to "UU" Jul 03 12:50:37 UU is reserved Jul 03 12:50:40 cant be Jul 03 12:50:55 think it's the sign that it's loaded /used Jul 03 12:50:58 maybe rtc is using the same addr as one of reserved i2c addresses ? Jul 03 12:51:11 could be.. I dont know Jul 03 12:51:35 I would not use hwclock_i2c but I would use i2cdetect first.. just to make sure device is working Jul 03 12:51:36 the guide from adafruit does exactly the same, and as sayed on angstrom it worked Jul 03 12:51:48 oh.. Jul 03 12:52:37 i posted the link to the guide. I did exactly the same but when I want to do hwclock commands they fail Jul 03 12:54:27 hopefully the following is not too much, but i think it is too less fro pastebin: Jul 03 12:54:31 hwclock -r -f /dev/rtc1 Jul 03 12:54:32 hwclock: Timed out waiting for time change. Jul 03 12:54:34 hwclock: The Hardware Clock registers contain values that are either invalid (e.g. 50th day of month) or beyond the range we can handle (e.g. Year 2095). Jul 03 12:54:42 BennyB_, I got my BBB just two days ago Jul 03 12:55:11 BennyB_, I don't know if I can help, but I would suggest you to use i2cget directly to read registers you want to read Jul 03 12:55:18 having mine a litte bit longer, also build a custom kernel for it Jul 03 12:55:51 ok, i'll try to learn how i2cget works Jul 03 12:55:57 I still have to do that part in C++ for my chip Jul 03 12:56:13 I'm not that linux freak, im only c++ coder *g* Jul 03 12:56:16 probably hwclock-i2c is also a program that locks device and reads it Jul 03 12:56:42 or maybe script using i2cget ;) Jul 03 12:58:25 is ther acommand to "un-echo" / uninstall a device from i2c bus? Jul 03 12:58:27 BennyB_, I found this https://github.com/ajaykumarkannan/Beaglebone-I2C Jul 03 12:59:02 it's a wrapper around open and ioctl C functions such that you can use c++ class to operate over i2c Jul 03 12:59:13 I want to use it myself Jul 03 12:59:17 didnt test it ! Jul 03 13:01:32 I also found some weeks ago this, but the RTC thing must be runb at startup from an bash script, I don't want to write a c++-program for it - only if it is needed Jul 03 13:01:35 https://github.com/piranha32/IOoo Jul 03 13:02:25 sorry, it tells that i2c is not yet done Jul 03 13:02:30 in that repo Jul 03 13:04:03 there should be a driver to set hwclock at boot over i2c Jul 03 13:04:29 for his chip ? Jul 03 13:04:42 pretty sure its been done before somewhere Jul 03 13:04:57 might need tweaking Jul 03 13:05:26 but the question is where *gg*, my google didn't find anything. may bee i feed it with the wrong keywords Jul 03 13:05:42 ds1307 is a standard part Jul 03 13:05:44 stt_michael, I am sure there is no i2c driver for my max21100 chip xD Jul 03 13:05:52 aik Jul 03 13:05:55 maybe Jul 03 13:07:10 I'm guessing its not the same commands/addresses? Jul 03 13:09:10 I'm repeating, but the adafruit guide did work on angstrom with kernel 3.x (don't know exactly) but now on wheezy 3.8.13-bone56 Jul 03 13:09:32 https://www.kernel.org/doc/Documentation/rtc.txt Jul 03 13:09:34 I have to go for awhile be back soon Jul 03 13:09:44 totally different beast angstrom Jul 03 13:09:53 and likely vintage kernel :) Jul 03 13:10:04 will take a peak Jul 03 13:16:10 BennyB_, take a look at http://www.raspberrypi.org/forums/viewtopic.php?f=44&t=16218 Jul 03 13:16:25 its for the pi, but the debian-isms should be equivalent Jul 03 13:16:37 assuming the max is compatible with the 1307 Jul 03 13:23:53 long and short it seems to be a cludge Jul 03 13:53:49 hm, the adafruit guide about raspi is nearly the same as the one for bbb, but as said, i fail ath the command hwclock -r or -w Jul 03 13:55:55 BennyB_, in comments they say debian has a bug and is not loading modules when it is suppose to ? or something like that ? Jul 03 13:56:12 BennyB_, and they even suggested a dirty hack/walkaround Jul 03 14:00:47 ok, I'ver found the posting on the site I try it Jul 03 14:02:31 BennyB_, stt_michael posted a link Jul 03 14:05:39 yes, I'm currently reading the website Jul 03 14:09:20 hi guys i need some help. I am trying ot request a pwm pin and have disabled the hdmi output to make that pin available. the pin in reference is p8_45. i load the overlay but then get this: http://pastebin.com/n8N8rgvU How should i go about loading the overlay correctly? Jul 03 14:11:38 mistawright, have you seen http://hipstercircuits.com/enable-pwm-on-beaglebone-with-device-tree-overlays/ ? Jul 03 14:13:17 ill take a look. i just figured the overlays in /lib/firmware would work out the box Jul 03 14:23:29 could somebody give me a brief hint what to do with a fresh compiled image... Jul 03 14:23:57 I am somehow lost with the step to transfer it ... Jul 03 14:36:58 laura_h, what instructions are you following? Jul 03 14:43:59 stt_michael, should i not be able to export the dtbo for a pwm pin that exits in /lib/firmware? Jul 03 14:45:09 that article was more confusing than anything. from looking at the dtb for pwm pin p8_45 it is setup correctly Jul 03 14:45:18 i am just not sure why it is unable to request the pwm pin Jul 03 14:47:57 stt_michael: which steps I follow? Jul 03 14:48:08 https://github.com/RobertCNelson/bb-kernel/tree/am33x-v3.8.13.x Jul 03 14:48:23 so, I build my kernel with the image Jul 03 14:49:33 laura_h you can use this guid how to build kernel: http://eewiki.net/display/linuxonarm/BeagleBone+Black Jul 03 14:49:49 and have an image in deploy/https://github.com/RobertCNelson/bb-kernel/tree/am33x-v3.8.13.x Jul 03 14:50:06 heh yeah I was about to say .. follow the eewiki guide :) Jul 03 14:50:16 sorry, wrong copy: deply/3.8.13-bone53.zImage Jul 03 14:50:39 you have a kernel, yes, laura_h ? you need to copy that to your boot partition Jul 03 14:50:54 should be able to jump to http://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-InstallKernelandRootFileSystem Jul 03 14:51:02 but scan the first bit in case :) Jul 03 14:51:26 mistawright, if you're lucky it works out-the-box .. but don't guarantee that all the settings will be right for your board/kernel/etc etc :0 Jul 03 14:51:27 :)*( Jul 03 14:51:30 kernel goes in the boot directory of the rootfs, not the boot partition Jul 03 14:52:10 thurgood, not the way I know :) Jul 03 14:52:23 media/boot is the boot partition ;) Jul 03 14:52:38 so it goes to /boot/uboot Jul 03 14:52:42 right? Jul 03 14:53:12 with debian it's simply /boot/ Jul 03 14:53:32 depends whether you're on the device, or an SD card Jul 03 14:53:33 but if it is an sdcard you'd better do that offline and simply mount /dev/sdX to /media/boot Jul 03 14:53:36 :) Jul 03 14:53:44 hm', confused, is Ubuntu a Debian or not? Jul 03 14:53:56 ubuntu<>debian no Jul 03 14:54:05 ubuntu is somehow a spinoff of debian Jul 03 14:54:06 it's a modified debian, sort of Jul 03 14:54:07 they're similar .. but not the same Jul 03 14:54:18 therefore the q reg. boot-dir Jul 03 14:54:40 ubuntu generally forks from debian unstable then changes a bunch to the point that they're fairly different Jul 03 14:54:57 * BennyB_ is better silent now, as too many cooks make a bad meal Jul 03 14:58:26 sorry when I reask, but I still don't get it reg. upgrade Jul 03 14:58:43 I have my kernel, and my already runnign BBB Jul 03 14:58:53 so, the SD should be already be set up properly Jul 03 14:59:14 is it sufficient to copy the newly compiled zImage over the old zImage? Jul 03 14:59:41 or do I have to do something else (e.g. upgrade some dir-struc) Jul 03 15:02:35 In http://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-CopyKernelFiles Jul 03 15:02:57 it is mentioned to copy KernelDevice Tree Binaries + Kernel Modules Jul 03 15:03:14 From where do I get them? Jul 03 15:14:41 laura_h, scroll up ;) Jul 03 15:16:43 I think, I figured it already out :) Jul 03 15:16:51 Just have to try Jul 03 15:23:46 no, still confused Jul 03 15:23:51 :( Jul 03 15:24:44 I've found the kernel image, the dtbs, modules and firmware Jul 03 15:25:35 BUT on the page it mentions at first step to CopyRootFile System Jul 03 15:26:00 but from where do I get these armhf-rootfs-*.tar???? Jul 03 15:27:33 can I just use the boot/uboot ? Jul 03 15:31:29 the rootfs/tar etc will be built by the scripts .. they should appear in a 'deploy' folder with RCN's scripts normally .. so try there Jul 03 15:31:37 otherwise, if you have a working rootfs laura.. don't worry Jul 03 15:32:36 no wait .. you Download the rootfs image .. debian-blah-blah on that page .. http://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-RootFileSystem Jul 03 15:32:51 yeah, don't worry that's what my mum told me as well ;) Jul 03 15:33:11 Just scan through that page from the top .. even if you don't DO all of it :) just to get the idea k? Jul 03 15:33:55 ok, then lets just replace the old zimage with the new one and then replace the dtbs-dirs Jul 03 15:34:20 yup that should work .. make sure your dtbs/image/modules all match :) Jul 03 15:34:44 yeah, that's the strange thing, cause Jul 03 15:34:54 I don't have a dir called 'module' Jul 03 15:35:01 nor a dir called 'firmware' Jul 03 15:35:06 just dtbs Jul 03 15:35:11 right .. need to look them out .. Jul 03 15:35:24 you might need to do something clever to 'extract' them from the kernel tree Jul 03 15:36:10 one stupid question: how does the kernel then finally recognize which version it is Jul 03 15:36:21 is it built in or is it a file Jul 03 15:36:26 which should be changed? Jul 03 15:49:22 fine, I did it :) Jul 03 15:50:03 worked but with little bit different dir-structure. thx Jul 03 16:19:54 'gratz laura .. its a learning process :) Jul 03 17:42:59 anyone know what the byte ordering of the Cortex in the BeagleBone Black is? Jul 03 17:43:14 I was under the impression it’s big-endian but a configure test just reported it as little Jul 03 17:49:17 pretty sure its big endian Jul 03 17:50:56 i may ne wrong Jul 03 17:50:57 looking it up Jul 03 17:51:29 , Jul 03 17:51:29 The Cortex-A8 treats Endianess separately for instructions and data. Instructions are all Little Endian (LE) while data can be interactively switched between LE and BE. There is an instruction which you can use to switch: Jul 03 17:51:38 thats for omap35x Jul 03 17:51:39 hm Jul 03 17:59:55 has digikey ever had stock of th ebeaglebone? Jul 03 18:00:06 i've bought a few hundred now, and we always end up going somewhere else. Jul 03 18:00:38 disappointing, because robert "the debian" nelson says he gets paid based off of digikey orders. Jul 03 18:00:50 err, mentioned that on the newsgroup. Jul 03 18:01:06 why wont digikey let me give them my money? :( Jul 03 18:10:10 wheredabone: I'll ping Circuitco today about status of Digikey orders. I know they get boards, but the % allocation is generally based on the % of orders in. Jul 03 18:25:55 jkridner: http://exadler.myshopify.com/products/beaglebone-black had over 1800 in stock last time I ordered... Jul 03 18:26:11 odd Jul 03 18:26:24 don't know where they got them. Jul 03 18:26:24 that's what they claimed at least. Jul 03 18:27:03 we ordered 150 or so, so they at least had a few. Jul 03 18:27:29 of what they claimed. Jul 03 18:28:31 nobody should have more than 200 stock ever .. from what I understood .. lol Jul 03 18:40:06 <_av500_> jkridner: thanks for the latest SW link Jul 03 18:40:16 _av500_: ? Jul 03 18:41:51 _av500_: you mean on http://beagleboard.org? Jul 03 18:42:27 <_av500_> yes Jul 03 19:01:40 isn't that where it always is? Jul 03 19:01:52 wasn't linked off the home page clearly. Jul 03 19:02:04 ah Jul 03 19:03:04 also, Exadler doesn't have stock Jul 03 19:33:17 What programming language (bonescript, python, etc.) are people using to program the "uC" (GPIO, ADC pins) on the BBB? Jul 03 20:41:22 I'm trying to develop a program using qt for a BBB runing debian testing and qt4, anyone have any idea how I can get a qtmake2 for my desktop system. Jul 03 20:41:40 it's apparently part of the cross tool chain Jul 03 20:42:30 I'm trying to use the linaro cross tool chain from rcn's notes Jul 03 20:43:16 I guess I should also say that currently I'm trying to use qt4 Jul 03 23:23:06 hello i was wondering where i could purchase a sensorcape? Jul 03 23:23:13 i cant seem to find one anywhere Jul 03 23:24:28 jkridner might know .. :) Jul 03 23:25:33 'oh really Jul 03 23:27:50 Wanted to get the word out http://specialcomp.com/beaglebone/ has the black in stock for $55 limit 2 Jul 04 01:01:36 are there any extra USB ports on the BBB that are available on other pins? Jul 04 01:01:49 no Jul 04 01:02:07 veremit, ok thanks Jul 04 01:02:07 the processor only has the two ports .. host and client Jul 04 01:02:12 i see Jul 04 01:02:17 you can tack a hub on ;) Jul 04 01:02:23 chip or brick Jul 04 01:02:24 :) Jul 04 01:02:35 chip or brick? Jul 04 01:02:43 usb2514 for example Jul 04 01:02:58 or a $20 computer parts ditty Jul 04 01:03:19 oh, i see Jul 04 01:04:11 hehe Jul 04 01:12:23 are usb hubs reliable? last time i recall using one with linux, i seem to recall it being damned flakey. but that was quite some time ago Jul 04 01:12:43 with the beaglebone .. its not perfect .. far from it Jul 04 01:12:50 but with mainline kernels .. its usable Jul 04 01:12:50 hmmm Jul 04 01:13:09 does the BBB have an i2s port? Jul 04 01:13:27 yes Jul 04 01:13:38 there's an mcasp too Jul 04 01:13:44 mcasp? Jul 04 01:14:04 oh, can that be used to get audio off the board? Jul 04 01:14:18 think so Jul 04 01:14:37 if i poll pru data memory from the arm while the pru is also reading, will that slow the pru down? Jul 04 01:15:25 pru is a separate core afaik Jul 04 01:20:55
