**** BEGIN LOGGING AT Wed Nov 27 03:00:00 2013 Nov 27 06:08:40 haha i found #beagle on first attempt great.... now I was wondering why the compatibility list of "Black" includes an HDMI shield ? Nov 27 06:09:12 beagles dont' have sheilds Nov 27 06:09:31 i mean cape* Nov 27 06:11:00 ok I got the idea after a few reads sorry for wasting your time Nov 27 06:19:13 why? Nov 27 06:19:34 you can put an hdmi cape on a bbb Nov 27 08:51:38 how to change the i2c bus speed in BBB on the fly ? Nov 27 08:52:33 i want to set it to 400 kbps Nov 27 08:54:08 dfa: https://www.google.com/search?q=linux+set+i2c+speed Nov 27 08:56:13 KotH:it says we need rebuild the drivers.is there any way to do it on the fly? Nov 27 09:05:04 dfa: afaik the DT specifies the speed too Nov 27 09:05:12 dfa: so, load the right dtbo Nov 27 09:29:40 hii Nov 27 09:30:32 can i load my window based communication application on begale board black Nov 27 09:30:35 ?? Nov 27 09:37:13 no Nov 27 09:37:24 if you mean microsoft windows Nov 27 09:37:37 Are the Kernel sources of validation release 2.6.32 available online? I can see the image download link but cannot find the sources. I am trying to develop a new camera driver for the XM board. Nov 27 09:38:21 image from where? Nov 27 09:38:49 what ships with the board? Nov 27 09:39:13 yes. I also see the image download link on Beagle web site. Nov 27 09:39:20 right Nov 27 09:39:31 the image can be rebuilt with oe/angstrom Nov 27 09:39:40 that will also produce sources Nov 27 09:39:55 how can i load a different u-boot.img from a already booted u-boot console ? Nov 27 09:40:08 though I dont know whit version/git branch is to be used Nov 27 09:40:21 rob_w: bootm? Nov 27 09:40:21 Yeah. I am trying to compile corresponding sources. I can get the Linux 2.6.32 kernel from the Linux repository but I guess I have to apply patches to it. Trying to Nov 27 09:40:30 figure out where to get the patches from. Nov 27 09:40:37 cameraDriverDev: patches are all in oe/angstrom Nov 27 09:41:18 best is to wait for jkridner to wake up Nov 27 09:41:57 :).. Thanks. Will try and look around oe/angstrom Nov 27 09:59:07 av500, the u-boot i am stuck on is giving me "Wrong Image Type for bootm command" for a u-boot.img Nov 27 10:07:22 rob_w: probably you're feeding it a zImage then... bootm needs a uImage Nov 27 10:08:10 rob_w: plus, it sounds like you are trying to chainload. Nov 27 10:11:22 LetoThe2nd, i am stuck on a wron u-boot Nov 27 10:11:43 and i either need to load a different one or manage to boot my kernel + fdt on this one Nov 27 10:12:21 well then replace it? Nov 27 10:12:30 well i cant Nov 27 10:12:42 its loading the one on the internal mmc Nov 27 10:12:46 which is the bad one Nov 27 10:13:02 so delete it Nov 27 10:13:06 no? Nov 27 10:13:17 from u-boot console ? Nov 27 10:13:18 it can also be replaced.... erase, cp.b Nov 27 10:13:24 hmm Nov 27 10:13:26 right Nov 27 10:13:34 on BBB? Nov 27 10:13:38 yes Nov 27 10:13:40 hold boot button to boot from sd, no? Nov 27 10:13:45 regardless of emmc Nov 27 10:14:44 doent work Nov 27 10:14:49 ? Nov 27 10:14:59 let me try some more Nov 27 10:15:12 boot button will change the boot order to sd first Nov 27 10:15:16 that works for sure Nov 27 10:15:16 never used that also our cape might interfere Nov 27 10:15:26 cape fear Nov 27 10:19:17 hmm pressing it brings me to the CCCC Nov 27 10:19:32 good Nov 27 10:19:34 so that tells me that it doesnt find my u-boot on the sdcard, right ? Nov 27 10:19:35 thats the ROM Code Nov 27 10:19:37 right Nov 27 10:19:42 now fix your card Nov 27 10:19:46 :) Nov 27 10:20:11 must named u-boot.img Nov 27 10:20:17 MLO Nov 27 10:20:20 you need MLO Nov 27 10:20:23 ah right Nov 27 10:21:55 crap Nov 27 10:22:19 mlo is on but still the CCCC , so my sdcard partition is not good i guess Nov 27 10:23:29 active Nov 27 10:23:34 it must be Nov 27 10:23:37 aka bootable Nov 27 10:23:40 my bbb should have shipped by now Nov 27 10:23:46 it hasn't Nov 27 10:23:48 afraid.tiff Nov 27 10:25:28 av500, fixed Nov 27 10:25:30 thx Nov 27 10:25:40 now back to original task .. Nov 27 10:26:35 maybe you have some hints .. about the following Nov 27 10:27:35 i found that the original u-boot env trys to detect the external mmc and boot but it gets stuck if it does find the card but with a wrong partition layout or a correct layout but missing the files Nov 27 10:32:00 actually .. Nov 27 10:36:14 how do i provide u-boot on emmc a valid environment ? Nov 27 10:36:33 you can hard code one Nov 27 10:36:37 or use uEnv.txt Nov 27 10:37:00 hmm i do have a uEnv.txt so maybe its not valid Nov 27 10:48:41 Angstrom feed seems broken for BeagleBoard XM. Some kernel packages are for 3.2.28 while others are for 3.7.0. These should be incompatible with each other unless I am missing something. http://feeds.angstrom-distribution.org/feeds/v2012.12/ipk/eglibc/armv7a-vfp-neon/machine/beagleboard/ Nov 27 10:49:01 cameraDriverDev: what camera btw? Nov 27 10:50:27 It is a camera with a parallel interface that my colleague has put together. It has no I2C control lines just data automatically flowing on the parallel interface with HSYNC and FSYNC. The driver should be similar to existing Aptina driver with all the controls stubbed out. Nov 27 10:51:55 The same code could be used with any camera input that just produces output on parallel interface. For example, one could potentially use a ADC converter to convert analog video and put it on the parallel interface. A driver for this might already exist but I can't seem to find one. Nov 27 10:52:20 hmmm feels like sourcing emmc uEnv.txt is not working Nov 27 10:59:40 logs? Nov 27 11:00:15 rob_w: note that uEnv is usually sourced when you boot, not when you interrupt the boot Nov 27 11:00:30 I find that stupid, but that's me Nov 27 11:00:35 well Nov 27 11:00:42 my own uboot also source preEnv.txt Nov 27 11:00:51 so I have an env on the uboot cmd line Nov 27 11:01:00 sec Nov 27 11:01:09 well, after mittach Nov 27 11:01:19 kk Nov 27 11:17:31 is it still valid that if i set a bootdelay=0 that it never stop even if there are characters on hte serial console ? Nov 27 11:27:39 hi Nov 27 11:28:02 is it possible to run win ce 6 on beagle bone black Nov 27 11:28:37 so i solved that gstreamer-plugins-bad plugin not building due to kernel incompatibility, Solution :- disable plugins what u don't need in the .inf file and it just compiles fine. some plugins are dependent on another lib which is not supported in the kernel version and bla bla, so if anyone is Stuck at building gstreamer1.0-plugins-bad due to that problem, just modify the recepie and remove the not needed packages. Nov 27 11:29:10 anyone experienced in win ce Nov 27 11:35:06 kevin : which version of kernel are you using? Nov 27 11:37:28 hi all Nov 27 11:37:46 hi Anguel Nov 27 12:21:54 where could i circumvent the stupid mmc numbering in the kernel .. so my emmc is always 0 and the other 1 Nov 27 12:29:32 hi Nov 27 12:34:38 is anyone here familer with uenv.txt Nov 27 12:35:35 the examples i'm finding are not doing what i want which is: insert sd card but have it boot from the emmc Nov 27 12:39:13 johnwalkr2, i think this happens automagically if your sd card is not bootable Nov 27 12:40:49 i know Nov 27 12:40:52 my sd card is bootable Nov 27 12:41:24 the problem is that i edited a file on there, causing it to not boot. the only system i have that can fix it is my beaglebone black Nov 27 12:41:54 the emmc is bootable, but i need to boot the emmc and also have the sd card available so that i can edit a file on the sd card Nov 27 12:42:07 no matter what i try, it tries to boot the sd card Nov 27 12:42:22 plugging the sd card in after booting doesn't appear to work either Nov 27 12:43:21 it seems like if the sd card is bootable, it boots it regardless of what the uenv.txt says. is that right? Nov 27 12:44:59 uenv.txt is read after boot Nov 27 12:45:09 so yes Nov 27 12:45:50 why don't you edit the file on your pc? :) Nov 27 12:47:14 i can edit the uenv.txt file on my mac, since it's on the boot partition which is FAT Nov 27 12:47:25 does anybody know if the precompiled Device Tree files for UART from Angstrom work under Arch Linux as well? Nov 27 12:47:56 I cannot get the UARTs to work on my BBB Nov 27 12:47:57 but i tried to edit the file on the ext3 partition using my mac and it made a corrupt file that shows up as a folder Nov 27 12:48:10 so basically it made things worse Nov 27 12:49:00 so if an sd card is bootable, there is no way to have it inserted in the beaglebone black and NOT boot from it? Nov 27 12:49:30 johnwalkr2, I don't know, maybe the others know Nov 27 12:51:41 ok. hopefully someone else knows. other info: my uenv.txt file on the sd card is: mmcdev=1 bootpart=1:2 mmcroot=/dev/mmcblk1p2 ro Nov 27 12:55:05 hi how boot beagle board from SD? Nov 27 12:56:13 lol we need to trade problems Nov 27 12:56:19 i am trying to get it to NOT boot fro sd Nov 27 12:56:42 johnwalkr2: what? Nov 27 12:56:56 i have my board with Angstrom Nov 27 12:57:22 and in eMMC i have many library Nov 27 12:57:40 how i can do for copy this library in SD and run my board directly from SD? Nov 27 12:58:11 you want the sd card to have the same system as the mmc? Nov 27 12:58:18 a copy of it? Nov 27 12:58:30 yes Nov 27 12:58:34 sam system as the emmc Nov 27 12:58:46 and for example in my emmc Nov 27 12:58:51 at start Nov 27 12:58:52 you can use dd Nov 27 12:59:11 i do opkg install qt4-embedded --force-depends Nov 27 12:59:20 opkg install libqtcore-dev Nov 27 12:59:23 ecc... Nov 27 12:59:26 in my emmc Nov 27 12:59:43 now i want all emmc in my sd Nov 27 12:59:53 you have undstand? Nov 27 13:01:05 i think if you boot with the sd card plugged in, is should boot to the mmc and the sd card should be accessible as /dev/mmcblk1 Nov 27 13:01:07 i use BBB-eMMC-flasher-v2013.06-2013.10.20.img and after boot i install qt4-embedded, libqtcore-dev libqtgui-dev Nov 27 13:01:23 but i am not entirely sure if it will show up as mmcblk1 or mmcblk0 Nov 27 13:01:53 and you say copy all emmc in sd with dd? Nov 27 13:01:55 can you boot the beaglebone with the sd card installed and type: ls /dev/mmc* Nov 27 13:02:42 johnwalkr2: yes but after? Nov 27 13:02:53 i have in emmc: many libraries, my app Nov 27 13:02:57 i know Nov 27 13:03:01 ecc.. Nov 27 13:03:11 please tell me teh output of: ls /dev/mmc* Nov 27 13:03:15 stupid mmc numbering ... may all flees from hell eat you Nov 27 13:03:16 wait Nov 27 13:03:31 and i can tell you the command to copy the entire mmc to the sd card Nov 27 13:04:47 johnwalkr2: is mmcblk1 Nov 27 13:05:22 there should be a mmcblk1 and a mmcblk0 Nov 27 13:05:28 yes Nov 27 13:05:32 SD is mmcblk1 Nov 27 13:05:41 ok Nov 27 13:05:44 as long as you are sure about that Nov 27 13:06:13 then the command to copy from mmc to sd is: dd if=/dev/mmcblk0 of=/dev/mmcblk1 Nov 27 13:06:36 the sd card has to be bigger than or equal to the mmc size, of course Nov 27 13:06:54 johnwalkr2: ok and after if i use a new BeagleBoard Nov 27 13:07:00 and insert this SD Nov 27 13:07:07 it start from SD with all my files? Nov 27 13:07:10 yes Nov 27 13:07:17 i try Nov 27 13:07:57 it will be a 2GB filesystem even if the card is bigger. you can resize it with this: http://elinux.org/Beagleboard:Expanding_File_System_Partition_On_A_microSD Nov 27 13:08:12 that is after you've verified that the sd card boots Nov 27 13:08:22 johnwalkr2: my SD is 4 GB Nov 27 13:08:38 so you will need to follow those instructions after to use all 4GB Nov 27 13:14:25 johnwalkr2: now i try Nov 27 13:14:29 just a moment Nov 27 13:14:42 it will take a long time to copy Nov 27 13:14:46 maybe up to 20 minutes Nov 27 13:15:08 but you are sure that this SD is bootuble? Nov 27 13:15:29 that will copy the bootable part of the mmc and all of your files Nov 27 13:16:00 so it will make 2 partitions on the sd card just like your mmc has Nov 27 13:18:42 when i do dd command it create automatically the 2 partition? Nov 27 13:19:09 yes, it copies bit by bit Nov 27 13:19:24 so even all the underlying partition tables etc get copied Nov 27 13:19:27 very useful command Nov 27 13:19:42 it's how you make image files as well Nov 27 13:19:52 so it's good for a backup you can restore to an sd card or mmc Nov 27 13:20:34 ok good Nov 27 13:20:39 the command of dd is? Nov 27 13:20:46 correct Nov 27 13:20:52 you can write Nov 27 13:20:54 ? Nov 27 13:23:22 how i can do for format my SD from windows? i have 2 partition in my SD Nov 27 13:24:47 you don't need to format it bfore you use dd Nov 27 13:25:11 i want format it beacuse in this sd there is emmc-flasher-angstrom Nov 27 13:25:32 i want reformat Nov 27 13:26:16 it will overwrite it Nov 27 13:26:35 it doesn't matter if you format it or not, and windows can't format for linux anyway Nov 27 13:26:50 from linux Nov 27 13:26:55 what is command for format SD? Nov 27 13:27:37 is /dev/sdb1 and sdb2 Nov 27 13:28:22 it depends on your system Nov 27 13:28:37 but you really don't need to format it before you start Nov 27 13:29:01 ubuntu i have Nov 27 13:30:11 i don't know Nov 27 13:31:19 i have to go, bye Nov 27 13:31:26 good luck with dd Nov 27 13:33:07 ok Nov 27 13:33:09 bye thanks Nov 27 14:14:15 when i boot my board from SD it dont start Nov 27 14:15:50 does not start as in leds do not flash or what happens ? Nov 27 14:16:04 i simply insert SD in slot and plug cable miniusb to my pc Nov 27 14:16:31 do u get any leds flashing or smth ? Nov 27 14:17:12 1st check your sdcard if u have there MLO and U-Boot and device tree Nov 27 14:17:14 d4 is fix and d2 flash Nov 27 14:17:27 do you have a serial cable ? Nov 27 14:17:32 to check the output of the console ? Nov 27 14:18:43 then i have 2 beagle bone black, un first i have on eMMC Angstrom and other my files(library, my app ecc..) i have inserted an SD and with dd if=/dev/mmcblk0 of=/dev/mmcblk1 i have copied all on SD Nov 27 14:19:09 after i insert this SD on second board and plug cable on PC Nov 27 14:19:20 ok but did u make the fat32 partition with MLO and u-boot ? Nov 27 14:19:33 i dont know Nov 27 14:19:33 or...w8 i'm wrong think so\ Nov 27 14:19:45 i did simply a copy Nov 27 14:19:51 don't have any clue if you do dd like this if it copies the whole sdcard Nov 27 14:19:53 i think that it copied all Nov 27 14:20:10 can u plug the sdcard into a linux box and check your partitions ? Nov 27 14:20:14 i can view SD on my linux? Nov 27 14:20:22 ok Nov 27 14:20:30 if the leds are flashing it means that something is running, the heartbeat led is flashing Nov 27 14:20:34 so something is working there Nov 27 14:22:05 but for boot from SD i need simply insert SD on Beagle and power on it? Nov 27 14:22:15 i do not know how it works with the uevn file from where does it takes the ramdisk Nov 27 14:22:52 if you have stuff on the emmc it will boot from emmc Nov 27 14:22:59 from uSD sorry Nov 27 14:23:42 ah so when i insert SD it start from SD Nov 27 14:24:02 i'm on my pc with sd plugged Nov 27 14:24:29 what do you see ? Nov 27 14:24:37 how many partitions Nov 27 14:25:33 2 Nov 27 14:25:48 Called angstrom an BeagleBone Nov 27 14:25:59 on the beaglebone you have MLO and u-boot right ? Nov 27 14:26:07 where? Nov 27 14:26:17 on partition called BeagleBone? Nov 27 14:26:20 yep Nov 27 14:26:47 yes MLO and u-boot.img Nov 27 14:26:59 try and get a srial cable Nov 27 14:27:01 serial* Nov 27 14:27:08 to see what the console is spitting out Nov 27 14:27:18 i think u-boot takes and starts loading the kernel Nov 27 14:27:24 i'm off, good luck! Nov 27 14:34:15 dont start ssh service Nov 27 14:34:25 i dont can comunicate with my board Nov 27 14:35:52 is possible that sd copy all files on eMMC? Nov 27 14:35:57 at start? Nov 27 14:36:32 because when my first board had BBB-eMMC-flasher-v2013.06-2013.10.20.img Nov 27 14:39:14 any help for me pllz Nov 27 14:39:16 ? Nov 27 16:42:54 I shall burn down my BBB -.- Nov 27 16:58:53 Kernle: ritual offering to the apease the gods? Nov 27 17:24:31 hello goodmorning Nov 27 17:24:40 i just have a very specific question Nov 27 17:25:42 is there any possibilities or has anyone try bonescript library in the deabian distro for the BBB??? Nov 27 17:26:42 hi to all Nov 27 17:26:48 i'm from italy Nov 27 17:28:20 can anyone write me if beaglebone black have a ce marking Nov 27 17:28:22 ? Nov 27 17:29:36 it's not consume electronics, thus does not need a CE certificate Nov 27 17:29:52 it's a development board, for people who know what they are doing Nov 27 17:30:41 billyrudi: http://2.bp.blogspot.com/-ee4KFeiSFDI/UfjNjOyV1ZI/AAAAAAAAHI0/hynj_4NhUFw/s1600/bbb_bottom_web.jpg Nov 27 17:30:58 KotH: I see a "CE" on the bottom of the board, is that a different CE? Nov 27 17:31:10 s5fs: that's an illusion ;) Nov 27 17:31:19 s5fs: you drank too much bad coffee this morning Nov 27 17:31:22 ;) Nov 27 17:31:33 KotH: how?? i'm still in bed! Nov 27 17:31:43 does explain the stale taste in my mouth though.. Nov 27 17:32:47 s5fs: unless you are living in japan/australia/new zealand, this would be the right time to get up and do something usefull ;) Nov 27 17:33:15 KotH: i got outta bed, confirmed the CE mark exists on a couple of the BBBs i have. now i'm back in bed haha Nov 27 17:33:24 the world is cold, not my fault Nov 27 17:34:03 billyrudi: btw: even if the bbb has a CE marking. you still need to prove that anything you build with it is still CE compliant Nov 27 17:34:56 I'm wondering if the CE mark has more to do with import taxes than anything else Nov 27 17:35:02 in this case, specifically Nov 27 17:35:24 anyways i guesss i'll go find pants and stuff. later crew! Nov 27 17:36:27 is there any possibilities or has anyone try bonescript library in the deabian distro for the BBB??? Nov 27 17:38:00 mcano: have you tried yourself? Nov 27 17:41:08 no because i don't want to waste time , as i need to develop as fast as possible... Nov 27 17:41:16 @KotH Nov 27 17:41:46 so i know that it works in angstrom.. by default but i dont know if it works in debian Nov 27 17:43:07 so i just need to know of a succesfull case... so i can try then Nov 27 17:45:02 mcano: well, it probably takes half an hour to try it. you dont even have that much time? Nov 27 17:45:37 no sir. Nov 27 17:47:53 KotH: Nah, just to watch that piece of crap burn \o/ Nov 27 17:50:26 Kernle: why are you so negative Nov 27 17:50:47 Kernle: you should be all happy for you have been blessed by the precense of a bbb Nov 27 17:56:02 I'm trying for like 3 weeks(!) now to install XBMC. And it just wont work Nov 27 18:54:34 <_av500_> so where does it fail? Nov 27 18:55:00 <_av500_> IIRC there was xbmc in angstrom atr some stage Nov 27 18:55:37 <_av500_> for the XM I think Nov 27 18:55:37 <_av500_> we even had a GSoC project about xbmc Nov 27 18:57:18 or just use an ubuntu image ... xbmc is in the archive Nov 27 19:18:01 Hey there, I need some help with my Beaglebone Black Expansion headers. Does somebody know which one of SPI1_D0 and SPI1_D0 is MOSI and which one is MISO? Nov 27 19:18:42 I looked for that a long time know but i just can't find it, would be great if somebody could help :) Nov 27 19:21:13 wow, that scared me.

Nov 27 19:54:15 anyone?! Nov 27 19:54:23 http://beagleboard.org/chat Nov 27 19:54:31 you don't need to ask to ask =) Nov 27 19:54:47 OK Nov 27 19:54:50 hi Nov 27 19:55:24 I want to connect a camera to BeagleBoard Black Nov 27 19:55:31 for image processing Nov 27 19:56:15 with resolution of at least 1024x768 pixels Nov 27 19:56:46 do you know any suggestions regarding a good camera? Nov 27 19:57:06 with available driver for BB? Nov 27 19:57:11 ? Nov 27 19:58:09 http://derekmolloy.ie/beaglebone/beaglebone-video-capture-and-image-processing-on-embedded-linux-using-opencv/ Nov 27 19:58:32 :) Nov 27 19:58:33 not sure about drivers, it depends on the OS you are running Nov 27 19:58:41 https://www.google.com/search?q=beaglebone+webcam Nov 27 20:02:27 how about connecting camera to GPIO? Nov 27 20:02:39 USB is not reliable/industrial Nov 27 20:02:41 ? Nov 27 20:06:08 neat idea, let us know how that goes! Nov 27 20:08:21 you would have to write your own driver in that case Nov 27 20:10:22 so does the ubuntu image allow you to connect over USB like the angstrom image? Nov 27 20:12:29 I'd like to run postfix/dovecot on my device, should I stick with angstrom or will ubuntu make my life easier? Nov 27 20:14:35 I have not bought any BB yet! just preparing to buy one Nov 27 20:15:46 need a near focus camera, cannot find any :( Nov 27 20:34:40 hi. Nov 27 20:35:16 is the usb host hot-plug issue solved? Nov 27 20:38:49 afaik, it is solved in the newest kernels from koen Nov 27 20:38:52 but i'm not sure Nov 27 20:40:52 ok. i'll try... Nov 27 20:41:00 i'll try when i revive my bbb Nov 27 20:41:26 i plugged a dc with inverted polarity and bbb no longer worked again... :( Nov 27 20:42:18 well, killing your device is not covered by the warranty Nov 27 20:42:23 right now i'm flashing the emmc... let's cross fingers Nov 27 20:43:08 plugging a dc adaptor with inverted polarity is a very common mistake... anyway i'm sure it's protected against that Nov 27 20:46:33 uhm Nov 27 20:46:34 no luck. Nov 27 20:46:44 i followed this Nov 27 20:46:46 http://hipstercircuits.com/unbrick-beaglebone-black-without-erasing-emmc/ Nov 27 20:46:49 to no avail Nov 27 20:46:55 any idea? Nov 27 20:49:32 Yet again... XBMC for BBB. Which distri to use? Nov 27 20:50:00 angstrom Nov 27 20:50:15 Tried that, didn't work :/ Seems like I got the wrong repo Nov 27 20:51:24 i downloaded the 2013.09.12 image, uncompressed, dd to the sdcard, then i inserted the sdcard on bbb, i dc powered the bbb... and nothing Nov 27 20:51:56 i tried to power it having pressed BOOT button and/or RESET button... and nothing Nov 27 21:03:50 KotH: any guess why it's not working my bbb? Nov 27 21:09:53 I still can't find a supplier w/ black in stocks before 13th of December. Nov 27 21:11:45 i got mine's (A6) at adafruit. i ordered two weeks ago and i received it in 5-6 days Nov 27 21:17:38 Kernle: you have to insert the card then power on while pressing the firmware load button on the board. Nov 27 21:19:30 anyone use bonscript on bbb or involved with the project on github? Nov 27 21:20:43 i did, but it does nothing. Nov 27 21:20:58 all leds are down... :( Nov 27 21:22:03 thow: if you powered the bbb with reverse polarity, then you most likely fried something Nov 27 21:22:44 thow: otherwise known as "letting the magic smoke out" Nov 27 21:24:10 really? Nov 27 21:24:15 but that's a very common mistake Nov 27 21:24:49 Where I used to work, we had a "polarity matters" pile of smoked electronics. Nov 27 21:24:50 yes, dropping your cell phone is also a very common mistake, yet it still breaks Nov 27 21:25:08 i can't believe bbb is not protected against that. i'm not talking about connecting 220v or 10A, i'm talking about 5v 1a, but reversed polarity. you can filter that out with a diode Nov 27 21:25:38 You should check the schematic and see if there's a diode. Nov 27 21:25:48 that's what i guess :) Nov 27 21:26:51 but my question is "how do i troubleshoot a bbb that doesn't lit any led when i power it (via usb or dc)?" Nov 27 21:27:25 thow: it's also not quite as simple as just a diode: http://www.edn.com/design/analog/4368527/Simple-reverse-polarity-protection-circuit-has-no-voltage-drop Nov 27 21:27:33 but I'm not an EE, so KotH can explain better than me. Nov 27 21:27:37 step 1: learn German Nov 27 21:27:46 I can't remember the other steps. Nov 27 21:28:08 thow: meter, scope, jtag Nov 27 21:28:29 later noobs! Nov 27 21:28:41 thow: you cannot put a protection diode on an input that has exactly the same voltage as you need for your circuitry Nov 27 21:28:47 thow: physically impossible Nov 27 21:28:55 because diodes have voltage drop Nov 27 21:29:10 thow: and the bbb assumes, that you know what you are doing Nov 27 21:29:20 alan_o: I love the name "polarity matters". I smoked a cellphone doing that once, too. Nov 27 21:29:20 KotH: hwaaaa? Nov 27 21:29:29 thow: putting reverse polarity power on a board is about the same as hitting your PC with a hammer Nov 27 21:29:34 myself: :) Nov 27 21:29:44 measure twice, connect once Nov 27 21:29:47 thow: it's might be a common mistake, but it's still stupid and damages your pc Nov 27 21:29:50 It's an expensive mistake, it hurts, and you... yeah Nov 27 21:29:56 you learn to check with a meter every single time in the future Nov 27 21:30:58 * KotH nearly fried 4kchf equipment with something more stupid Nov 27 21:31:07 :D Nov 27 21:31:26 so, is there anything i can do with my bbb? Nov 27 21:31:39 it's not very heavy, so I wouldn't suggest using it as paperweight Nov 27 21:31:51 does CCO still repair boards? Nov 27 21:31:51 funny :) but i don't know even if it's bricked Nov 27 21:31:54 unless you first cast it in a block of resin, perhaps with a small "polarity matters" sign Nov 27 21:31:57 thow: enshrine it, for future generations to learn Nov 27 21:32:00 they might have used to. Nov 27 21:32:18 alan_o: cco does repair boards, but it's not worth the p&p Nov 27 21:32:23
