**** BEGIN LOGGING AT Sat Jun 29 02:59:59 2013 Jun 29 03:07:27 christ did someone break emmc? Jun 29 03:12:03 just you Jun 29 03:28:28 probably my old toolchain Jun 29 03:28:50 gah "Error: unrecognized option -mauto-it" what is koen using?.. Jun 29 03:31:26 @#$!@#$ codesourcery needing a email for a download link Jun 29 03:31:34 lol Jun 29 03:32:03 wouldn't expect less from my former employer :P Jun 29 03:32:55 Heh, my current employer is pretty terrible when it comes to downloading the software Jun 29 03:32:58 "we" make Jun 29 03:34:33 Anyways, the new beagle bone black is nice. Been playing around with it the last few days. Jun 29 03:39:00 What is persistant across flashing eMMCs? Jun 29 03:39:20 I flashed 2 BBBKs with the same image and only the one works Jun 29 03:39:39 the one that doesn't work, I've tried about 30 times now\ Jun 29 03:39:45 with different distros, etc Jun 29 03:40:16 Worked for me on the first try. Jun 29 03:40:22 Windex007: known issue Jun 29 03:40:25 Tossed Debian Squeeze Jun 29 03:40:28 on it Jun 29 03:40:52 Definitely faster, now I'm just trying to figure out what I want to do with the little thing. Jun 29 03:41:29 mranostay is it a known issue? What's the solution? Jun 29 03:41:51 or, should I say, what should I be googling to find the solution? Jun 29 03:41:55 Windex007: read a bunch of block from emmc to flush it Jun 29 03:42:26 like dd if=/dev/mmcblk0 of=/dev/null count=100000 Jun 29 03:42:38 * mranostay wishes he was kidding Jun 29 03:43:08 so whats the best way to do that if it wont even boot at this point? Jun 29 03:43:20 try again Jun 29 03:43:23 er... can I boot from an SD card with a full image? Jun 29 03:43:31 yeah you can do that too Jun 29 03:43:49 ok. Thank you very much. I'll give that a shot. Jun 29 03:44:22 * mranostay better send this patch off before another beer Jun 29 04:16:53 have we quietend down now Jun 29 04:16:55 ? Jun 29 04:24:50 this place is lame Jun 29 04:29:41 mastiff, LAME?....I can walk just fine thank you.... Jun 29 04:35:21 trying to go fast, compiling options for neon coprocessor Jun 29 04:45:50 dammit i know what the problem is Jun 29 04:46:07 emmc only works as built cape overlay Jun 29 04:48:30 as in FIRMWARE_IN_KERNEL option or whatever Jun 29 04:59:43 <_av500_> yarn Jun 29 05:02:34 cat! Jun 29 06:22:54 <_av500_> mranostay: always so negative Jun 29 06:51:00 nolame? Jun 29 07:07:46 embed, ka6sox-away flash was installed upside down Jun 29 07:12:52 mrpackethead: oops! Jun 29 07:12:59 * emeb_mac has been there. Jun 29 07:13:45 hope you have extras - that usually kills 'em dead. Jun 29 07:13:59 yes, i bought enough kit for 10 Jun 29 07:15:08 emeb_mac: i might make up a construction guide for it Jun 29 07:15:16 jsut to help the non-designers Jun 29 07:15:24 not a bad idea. Jun 29 07:15:47 never ceases to amaze me Jun 29 07:15:56 how much info you assume is obvious Jun 29 07:15:58 is not Jun 29 07:16:13 mrpackethead, I'll do the same for the BoneTag Jun 29 07:16:15 no kidding Jun 29 07:17:10 im at home Jun 29 07:17:14 i have my home tools Jun 29 07:17:18 and i am thiking Jun 29 07:17:25 that my home bench is better than my work bench Jun 29 07:17:58 time to upgrade the bench at work. Jun 29 07:18:27 shoudl be better at work Jun 29 07:18:32 but when i put good tools on my bench Jun 29 07:18:36 then everyone wants them Jun 29 07:18:52 growl at them Jun 29 07:19:38 i inly have a 100M scope here Jun 29 07:19:42 just a wee big slow Jun 29 07:20:09 eh. I've got a 60MHz analog. works fine for many things. Jun 29 07:20:17 yup. Jun 29 07:20:25 this is a 100Mhz digital Jun 29 07:20:28 its amazing Jun 29 07:20:35 but i was just probling the oscillator Jun 29 07:20:53 I'd hihgly recommend these. $399, Rigol DS1102E Jun 29 07:21:04 we have 3 of them Jun 29 07:21:06 at work Jun 29 07:21:13 and one much faster scope Jun 29 07:21:20 but it does't get used much Jun 29 07:22:05 I was looking at the 150MHz gwInstek scope a while back Jun 29 07:22:12 emeb_mac: next run, we'll do machine assembly huh Jun 29 07:22:38 if you think there's enough volume for that. Jun 29 07:22:44 we can make a beagle-clone Jun 29 07:23:25 whoa - ambitious! Jun 29 07:23:28 how about calling it "beagleclone" Jun 29 07:23:45 beagleclone-grey Jun 29 07:24:15 leave off the eMMC and HDMI - ka6sox-away would be up for that. Jun 29 07:24:22 :-) Jun 29 07:24:31 i like the emmc Jun 29 07:24:32 anyway Jun 29 07:24:40 the photo of the bcc on yorur page Jun 29 07:24:57 ya - It's good except that it kills the GPMC on P8 Jun 29 07:25:13 would that happen to be the one that had its flash roudn teh wrong way Jun 29 07:25:25 i was looking at it, ( thats where i was assembling from ( Jun 29 07:26:01 don't think so - I fixed the parts before taking the pix Jun 29 07:26:11 its just that the st-logo Jun 29 07:26:18 is in the wrong palce Jun 29 07:26:40 yeah - someone else mentioned that. They must have changed the marking Jun 29 07:27:19 its hard to tell whicj way the bevel is Jun 29 07:28:33 in the photo that is Jun 29 07:28:38 right Jun 29 07:29:32 josh ( my programmer ) has almost finished wrirting the code for this Jun 29 07:29:43 so, i need to hurry up and get these ones finsihed for him! Jun 29 07:30:25 what kind of code? Jun 29 07:31:00 dmx Jun 29 07:31:15 cool Jun 29 07:31:23 four univereses Jun 29 07:31:25 bi-directional Jun 29 07:31:58 well - bedtime here Jun 29 07:32:01 l8rs Jun 29 08:24:33 I seek enlightenment -- I'm designing a board that is going to use the Black as its control processor, but I need the expansion headers and pin mux stuff explained a little so I make sure I don't configure anything to stomp on existing functionality Jun 29 08:32:37 been reading over BBB_SRM.pdf and I need to understand the expansion header chart better... it shows all the various possible pin assignments, but the defaults are the pin names listed on the left ?? Jun 29 08:51:17 mranostay: "my" cat is fuzzier than yours Jun 29 08:58:36 Ascendion: you can mux them however you want, also check the TRM for more info about pin muxing, etc Jun 29 09:28:01 Hello everyone, please help me! I have installed puredata from source on BBB (run lastest Angstrong Image)! when I run "$pd" I have error that require install tk and tcl So I installed the foloowing pakages: ///////////////////////////////// libtk8.5-0_8.5.8-r3.9_armv7a.ipk libtcl8.5-0_8.5.8-r9.9_armv7a.ipk tk_8.5.8-r3.9_armv7a.ipk tcl_8.5.8-r9.9_armv7a.ipk //////////////////////////////// But when execute "$pd"(use HDMI or x11vnc) I Jun 29 09:28:28 the below image: http://imageshack.us/content_round.php?page=done&l=img835/3754/ajj4.png&sa=0 that I can't drag terminal and puredata gui So I tested by execute command "$wish" and the same error occured! Maybe I need to install new packages? But When I connect to my BBB by execute "$ssh -X root@192.168.7.2" and execute "$wish" everything is OK. Please help me to run "$wish" without error use HDMI or x1VNC! Jun 29 09:29:52 am I not awake or why do those lines look like gibberish Jun 29 09:35:32 are you using a serial terminal to access the system ?? Jun 29 09:35:41 (usb/serial or whatever) Jun 29 09:35:51 or an SSH connection ?? Jun 29 09:36:07 Thanks, I use usb connection Jun 29 09:37:17 ok -- your error message says it all then -- its trying to set up a GUI and that takes either a connected HDMI display/keyboard/mouse or a remote X11 display using VNC Jun 29 09:38:01 (the vnc hookup would require a network connection to a computer running the VNC client software) Jun 29 09:39:22 GUI apps dont run on serial terminals :) Jun 29 09:39:51 Thanks, But I still don't understand! I connect to BBB use SSH or VNC by usb-ethernet virtual. I think the network OK & all my test use SSH or vnc or hdmi is seperate! Jun 29 09:40:57 dont use SSH at all -- just use VNC then run your command that failed.. or hook up kb/mouse/monitor (which gets you the on board Xserver) and run the command in the graphical desktop Jun 29 09:42:59 dm8tbr -- I'm still a bit confused -- are you saying that the mux is external to the CPU and selecting any specific pin/port association does not neccesarily mess with any "internal" connections on the board -- especially to the MMC channels that control the boot memory and SD card ?? Jun 29 09:44:01 Thanks , but the same error occured!(I only connected my BBB use HDMI or VNC seperately) Jun 29 09:44:33 OK -- no clue then why its failing to detect that its running in a graphical environment Jun 29 09:47:13 Thanks Ascendion, I connected to my BBB use a HDMI cable (with a mouse & a keyboard) then opened the terminal -> type "$wish" -> the same error occureed! Jun 29 09:58:01 cxp -- I dont actually own a BB yet so I'm not going to be able to help beyond what I've said so far Jun 29 09:58:54 hoping dm8tbr will clear up my question so I can be more confident about how to interface :) Jun 29 09:59:17 Ascendion, Thanks for your help! Jun 29 10:03:59 or maybe I dont need to ask -- just looked at the schematics -- the mux function has to be in the CPU so its entirely possible for me to reconfigure a pin that is critical to some other feature of the board Jun 29 10:07:15 Ascendion: sure, you have to make sure not to mess up otherwise necessary muxing. but pins that are used for something should be documented. Jun 29 10:08:52 not very clearly from what I have read -- matching up required onboard pins to header pins is not simple.... something of a design flaw... nothing on the expansion connector should have had any possibility of disconnecting an on board function Jun 29 10:14:42 Ascendion: not necessarily Jun 29 10:15:19 Ascendion: you can disable some on board features and then use the lines on the header. also it allows you to measure things that happen on those pins if you're curious. Jun 29 10:16:09 also keep in mind that this is a largely pin compatible second generation board, where the first one didn't have an eMMC (but there was an emmc cape) and hdmi (but there was an hdmi cape) Jun 29 10:16:12 one last question then -- the defaults are the mux setting in the "Name" column -- so if I dont change anything I get all the on board features and those specific IO pins ?? Jun 29 10:16:51 I don't have the srm at hand, but I'd use the DT that comes with the kernel you're going to use as the reference Jun 29 10:17:46 cause If I jump through some hoops with my pin assignments I can get what I think is everything I need (I2C, SPI, and an extra 20-something-odd GPIO pins) Jun 29 10:20:27 DT ?? Jun 29 10:20:40 device tree Jun 29 10:22:03 ty -- I guess there is a whole new bunch of acronyms to learn :) Jun 29 10:22:17 yes :) Jun 29 10:23:42 what really hurts is that enough of the PRU isnt exposed to handle couple of features I would have liked to implement with it without stomping on pins that appear to be needed for on board functions Jun 29 10:24:29 for pru things, better ask panto or mranostay :) Jun 29 10:24:50 * SpeedEvil idly wonders about uclinux on PRU Jun 29 10:24:52 there is also some PDF floating around that has even more details about pru it seems Jun 29 10:26:13 ya -- I went over it -- looked really cool for doing IO stuff that has to work at logic speeds :) Jun 29 10:26:31 beats the hell out of bit banging Jun 29 10:26:36 :) Jun 29 10:30:48 Ascendion: good luck Jun 29 10:31:43 watch out for all the pins you can't use so much, becuase the HDMI and emmc swallowed them, when the beaglebone when black Jun 29 10:32:20 Do you simply mean because they are awkward to use - in the case of HDMI - can you switch the function back? Jun 29 10:38:16 someone just add a section to the pdf that clearly documents what pins are compromised by default and what feature would be trashed by retasking Jun 29 10:39:11 and what driver has to be disabled to prevent conflicts with 2 pieces of code trying to use the same pin Jun 29 10:43:08 maybe easier to go back tot he bbw for some Jun 29 10:49:53 w = white ?? :) Jun 29 11:17:17 hi Jun 29 11:39:11 grrrrrr Jun 29 12:04:50 [kernel] koenkooi pushed 2 new commits to 3.11: http://git.io/g0nzmw Jun 29 12:04:50 kernel/3.11 598023c Koen Kooi: 3.11: import capemgr...

Jun 29 12:12:22 geeze Jun 29 12:17:01 bwaaaaak Jun 29 12:18:50 hi Jun 29 12:19:29 has anyone faced with probmles on bb xm in booting over nfs through ethernet cable ? Jun 29 12:20:15 kernel starts loading and freezes on mounting rootfs Jun 29 12:21:18 the weird thing that ethernet diodes dont blink at all Jun 29 12:21:52 pastebin your console output Jun 29 12:24:12 http://pastebin.com/1me6XkFj Jun 29 12:24:49 i will provide uEnv.txt too Jun 29 12:24:54 * mranostay pokes Jun 29 12:29:24 uEnv http://pastebin.com/uaUp2aU8 Jun 29 12:36:53 syrioosh: never done nfs booting, but shouldn't "rootpath=" contain something? Jun 29 12:42:42 i have seen others log in web (success mounting) and there rootpath filed were empty too Jun 29 13:25:47 <_Sy_> Hello Jun 29 13:34:58 has anyone successfully ported PWNPI or KAlI linux for BBB ? I am working on a pentesting project using either raspberry pi or BBB . Jun 29 13:38:21 I am stuck between whether to buy the raspberry Pi or the BBB for pentesting Jun 29 13:38:39 HAs anyone successfully installed kali linux on BBB ? Jun 29 13:39:42 bbb == more cpu, raspi = more os support Jun 29 13:40:06 google will be your friend fo finding out if it works Jun 29 13:41:19 rpi has definitely less OS support ... the images you get for it are usually bastardized non std. rebuilds of distros for ARMv6 Jun 29 13:42:13 while armv6 v armv7 for distro choices limits ubuntu since they dont do a non hardfloat/v7 version .. but that doesnt mean that the kernel support is better on bbb Jun 29 13:42:23 drivers/software/etc are far better supported on the raspi Jun 29 13:42:42 that said for simple pen testing without the need for spi/i2c/gpio etc - faster is probably better Jun 29 13:43:19 execpt that thr rpi only boots with binary blobs available, yes Jun 29 13:43:40 yes broadcom closed source soc Jun 29 13:43:41 :( Jun 29 13:43:42 you can run the BBB completely on opensource Jun 29 13:43:51 not possible with the Pi Jun 29 14:02:46 i check all forums including bbb , kali community , youtube and google Jun 29 14:02:52 checked... Jun 29 14:03:26 the closest I have come to is "the Deck" a pentesting and forensics platform for BBB Jun 29 14:04:10 but thanks anyways @maxinux aNd @ogra Jun 29 14:50:21 ok i found out my issue with NFS Jun 29 14:50:46 it doenst use eth0 instead usb0 in booting Jun 29 14:51:10 that can be set with the ip= kernel option Jun 29 14:51:33 it's well documented Jun 29 15:29:22 Does anyone know if/where there is/exists an example somewhere of the assembly programming on the PRU for the BBB to read an input from the P8/P9 pins ? Jun 29 15:29:39 yes Jun 29 15:29:47 And are willing to share it? Jun 29 15:30:24 ka6sox, Could you give me more information please or were you just saying 'yes' for the fun of it ? Jun 29 15:30:27 there is example code for this, I believe that Bas has some on his page Jun 29 15:30:30 Because some people do this. Jun 29 15:30:39 Bas ? Jun 29 15:30:40 let me see if I can link Bas' page Jun 29 15:31:19 ok Jun 29 15:35:06 which Beagle do you have? Jun 29 15:35:18 BeagleBoneBlack A5B Jun 29 15:35:52 are you planning on using a GPIO that is directly hooked up toe the PRU or a GP one. Jun 29 15:37:01 http://www.elinux.org/Ti_AM33XX_PRUSSv2#Beaglebone_PRU_connections_and_modes Jun 29 15:37:06 those are hooked up directly Jun 29 15:37:26 ka6sox, I intend on programming for the PRU in assembly to access the input on a pin in the P8 block which'll be via the GPIO that I have pinmuxed. So I am after an example of the assembly code used to do this Jun 29 15:38:22 I've setup the pinmux for pin 15 in mode 0x36 and I just need the code to put onto the PRU Jun 29 15:39:07 do you know assembly? Jun 29 15:39:12 this's what I'm learning Jun 29 15:39:24 Hence why an example would be nice Jun 29 15:40:03 I already have an example of flashing an LED on a breakout pin done by element14, but I haven't seen any reading in Jun 29 15:42:16 pin 15 of which PX? Jun 29 15:43:13 P8 Jun 29 15:43:33 So r31.t15 of the PRU Jun 29 15:43:54 Which's set to 0x36 so that it's set into mode 6 and also for input Jun 29 15:47:39 unfourtunately i can't make bb use eth0 in booting no matter what configuration I set Jun 29 15:48:14 Stanto, I guess he doesn't have example code there...let me see if another project did that. Jun 29 15:53:37 Stanto, I don't see one...guess we will have to write one. Jun 29 15:55:57 ka6sox, "we" ? Jun 29 15:56:31 the royal we? Jun 29 15:57:56 Stanto, I'll put it on my list...which right now puts it...somewhere in October or November.... Jun 29 15:58:08 2017 Jun 29 15:58:15 maybe it will just all out of the work being done for GSoC Jun 29 15:58:26 ka6sox, I've no idea what you're talking about. Jun 29 15:58:39 and right now my 3 minute eggs are at 11minutes and counting. Jun 29 15:59:26 Stanto, right now I can't take on another thing as I'm busy with GSoC and work... Jun 29 15:59:50 but I'm hoping, out of the work being done for GSoC that an example can just fall out of that and be posted. Jun 29 15:59:57 ka6sox, I don't believe anyone asked you to, and I don't know what GSoC is, I'm guessing it's chatting in irc, either that or that's what work is. ;) Jun 29 16:00:10 Google Summer of Code Jun 29 16:00:29 and that would be the Royal We :) Jun 29 16:01:11 * ka6sox goes to see if his boiled eggs are burned. Jun 29 16:01:42 ka6sox: are you the king now or what? Jun 29 16:03:11 mru, why yes, yes I am.... Jun 29 16:04:14 mru, I have been all my life too! Jun 29 16:04:36 as your father before you Jun 29 16:05:07 Tom Tomovich Jun 29 16:06:27 Hi ! what is the software used to make that king on scheme ? http://elinux.org/File:BoneGPIO.png Jun 29 16:06:52 *kind Jun 29 16:07:19 Hard Boiled....again Jun 29 16:12:09 Stanto, sorry, I thought there were examples of that. Jun 29 16:12:19 (and now I know there are not) Jun 29 16:14:28 yup Jun 29 16:17:48 "Hard Boiled" was an answer to my question...? Jun 29 16:21:41 bi Jun 29 16:21:44 no Jun 29 16:21:59 it was the state of his eggs Jun 29 16:22:02 found ! the response si "Fritzing" Jun 29 16:22:08 *is Jun 29 16:23:37 http://fritzing.org/projects/ Jun 29 16:55:57 <_Sy_> hello, anyone here? Jun 29 16:56:49 <_Sy_> ? Jun 29 17:31:48 <_Sy_> anyone here that can help me please? Jun 29 17:32:49 <_Sy_> did an upgrade and update on BBB today, now it won't boot unless I use my SD backup...but won't boot from eMMC...I made a backup of the eMMC to a gz archive. Jun 29 17:33:11 <_Sy_> my question is, how do I restore the eMMC from the gz archive, the gz archive contains a single img file. Jun 29 17:34:02 <_av500_> boot from SD Jun 29 17:34:05 <_av500_> a non flasher image Jun 29 17:34:14 <_av500_> then dd the backup over the network Jun 29 17:34:35 <_av500_> or so Jun 29 17:34:46 <_Sy_> sorry, how? I've booted from SD at the moment, what next? Jun 29 17:35:25 <_Sy_> I've got an ssh shell open on the BBB Jun 29 17:40:54 <_Sy_> Does this look correct? Jun 29 17:40:54 <_Sy_> dd if=/mnt/usbstick/bb2.eMMC.img of=/dev/sda Jun 29 18:33:43 <_Sy_> I've restored the eMMC from a backup I made last week, but it still won't boot, when I power up all four LED's come on and stay on...any suggestions? Jun 29 18:38:00 <_Sy_> There is something pretty wrong when you perform an update and upgrade and it ends up screwing your image. Jun 29 18:39:51 did you take the emmc out? Jun 29 18:40:27 <_Sy_> Take it out??? its fixed isn't it? Jun 29 18:40:38 thought maybe you unsoldered it Jun 29 18:41:04 <_Sy_> no, definately not, just did an opkg upgrade, followed by opkg update and it won't boot. Jun 29 18:41:20 did you take the sd out after reflashing? Jun 29 18:41:23 <_Sy_> this happened to be when I first got the board, hasn't happened again until today Jun 29 18:41:27 <_Sy_> yes Jun 29 18:42:33 try flashing a different image and make sure you don't interrupt it until all four LEDs stay on Jun 29 18:45:47 <_Sy_> will give it a go Jun 29 19:00:33 morning Jun 29 19:00:55 <_Sy_> evening :) Jun 29 19:02:45 UGT Jun 29 19:06:01 night Jun 29 19:14:07 what's the plural, is it "beaglebone blacks" or "beaglebones black"? I'm thinking, "courts martial" and similar, the adjective is left out. Jun 29 19:16:08 one beaglebone black, ten beaglebone black, it's like sheep Jun 29 19:16:51 <_Sy_> or BBB's :) Jun 29 19:17:30 or "ten black beaglebones" Jun 29 19:17:59 (is it a black bone of a beagle, or is it a bone of a black beagle?) Jun 29 19:21:40 blackbones Jun 29 19:45:22 I was hoping this fellow might parachute in and rescue us: http://i.imgur.com/EF1GKHF.jpg Jun 29 19:51:27 does anybody know where to send contributions / corrections for the future versions of bonescript? Jun 29 19:55:49 issues on github maybe t-szczyrba Jun 29 19:56:00 But which one? Jun 29 19:56:16 <_av500_> t-szczyrba: is is not on github? Jun 29 19:56:33 https://github.com/jadonk/bonescript that is the one i'm watching Jun 29 19:57:31 from one side https://github.com/jadonk/bonescript from other https://github.com/beagleboard Jun 29 19:58:01 is the jadonk repo more apropriate to include patches in the very first place? Jun 29 19:58:18 jadonk is jason k Jun 29 19:58:24 and it is his think Jun 29 19:58:29 so i'd say go to the source Jun 29 19:58:39 ok... now I see it is basically the same... Jun 29 19:58:41 it has more recent commits Jun 29 19:58:53 but forked Jun 29 19:58:58 the one on beagleboard is forked from the jadonk one Jun 29 19:59:08 yes, I see Jun 29 19:59:33 during the week you might poke him here Jun 29 19:59:44 usually mid morning Jun 29 20:01:18 should I send him the email, or make something like 'pull request' - the later is pretty complicated way of small patch inclusion... Jun 29 20:01:27 ? Jun 29 20:01:41 something you should ask him Jun 29 20:01:45 ok Jun 29 20:02:12 if you fork it and then make changes I think it is pretty easy to pull in your changes Jun 29 20:02:21 the problem is also that during the week I don't have too much time for such activity... Jun 29 20:02:41 and if he doesn't like them then maybe someone else might Jun 29 20:03:33 he seems pretty open to help Jun 29 20:03:40 i asked the other day about a road map .. Jun 29 20:03:46 yes, but I have some pretty cosmetic changes ( to straightforward make bonescript & bone101 working in non-standard port configuration ) Jun 29 20:03:46 he said .. yeah i should do that Jun 29 20:03:52 http://beagleboard.org/Support/BoneScript/roadmap Jun 29 20:04:00 an hour later he posted that Jun 29 20:04:57 fine... roadmap is pretty cool. But bonescript should also be made in such a way, that installation parallel to regular apache webserver should Jun 29 20:05:20 be simple not to include any corrections in js part of static website as well as bonescript Jun 29 20:05:22 who needs apache when you have node ;) Jun 29 20:06:01 I'd like to make some telemetry demo based on existing solution and I need all the php-s, modperls et consortes... Jun 29 20:06:14 i was just pulling your leg Jun 29 20:06:26 I've already compiled and installed all the postgresql, apache, modphp etc... Jun 29 20:06:48 then what about the people who like nginx Jun 29 20:06:52 Is here anybody interested in real-time BBB applications? Jun 29 20:06:59 the list goes on and on Jun 29 20:07:22 i would think a large number of people have grabbed a BBB to use the PRU Jun 29 20:07:30 I've applied xenomai patches to 3.8 tree with beaglebone patches in parallel Jun 29 20:07:54 <_Sy_> define real-time :) Jun 29 20:08:00 but see that almost nobody was interested in my announcement Jun 29 20:08:27 Xenomai-based real-time - no other linux solution gives such predictable perfromance, or am I wrong? Jun 29 20:08:49 t-szczyrba: there are other people working on that too Jun 29 20:08:50 have you looked at the pru? Jun 29 20:09:16 the only other said 'smoke, but no fire', and I have _the fire_ in my repo ;-) Jun 29 20:09:31 no... not yet. Jun 29 20:09:38 t-szczyrba: who was that Jun 29 20:09:51 i like the idea of leaving the kernel alone and using the PRU Jun 29 20:09:54 I've seen once in groups such a claim... but forget it ;-) Jun 29 20:10:23 but the PRU is something to control pins / basic protocol handling Jun 29 20:10:46 You cannot do much with PRU alone without any real-time OS support Jun 29 20:11:27 if I want to handle control over mod-bus with some complicated control flow PRU alone doesn't give me such ability Jun 29 20:37:41 i have some issues with the system recognising my beagle bone black Jun 29 20:37:52 anyone who can help me out Jun 29 20:46:48 Define 'the system'. Jun 29 20:47:03 Do you mean the global conspiracy of lizards that control our lives? Jun 29 20:47:52 Oh Jun 29 20:47:56 http://www.systemcomic.com/ Jun 29 21:11:23 Is it possible to power a Beaglebone Black with (external power supply 5V 2A) + (5V from the USB cable that comes from the computer)? Is it possible to have both at the same time? Jun 29 21:15:33 <_av500_> no Jun 29 21:15:39 <_av500_> one takes precendence Jun 29 21:17:29 Ok, but will it work anyway? What I dont want is the board being damaged. Jun 29 21:18:47 By working I mean being able to manage the beagle board through the USB client Jun 29 21:25:04 hello Jun 29 21:25:55 <_av500_> kjiu: it wont be damaged Jun 29 21:26:11 i'm trying to read a tmp36gz temp sensor and I'm getting really funny values. if I even hover my hand over the bbb and breadboard the "temp"/voltage drops Jun 29 21:26:20 Alright thank you Jun 29 21:26:44 <_av500_> goge: you are too cool Jun 29 21:26:49 lol Jun 29 21:27:26 i'm using the tmp36gz sensor, a half bread board and pin/pin 24awg jumper wire Jun 29 21:28:38 if I touch the sensor the temp drops... any ideas? Jun 29 21:31:09 <_av500_> you wired it backwards Jun 29 21:31:18 I don't even have to touch it, just get close. and the tempo isn't reading right either. Jun 29 21:31:44 that's what I thought... but I checked. lemme tripple check Jun 29 21:34:08 it's wired correctly Jun 29 21:36:22 yep. I flipped it around for giggles and the bbb shut off Jun 29 21:46:42 took it off the breadboard and hooked it up with allagator clips and it looks to be working correctly ish now. thoughts? Jun 29 21:49:58 values jump wildly. 12,13,12,13,11,9,10,14 ... is it just a cheep sensor? Jun 29 21:50:19 or imperfect connections? Jun 29 21:52:31 goge: something with stability of analog voltages / ground? Jun 29 21:53:39 goge: have you tried to read at least stable value of some voltage without instabilities? From some reference source for instance Jun 29 21:53:56 are those raw ADC values? Jun 29 21:56:26 goge: ADC input noise? Jun 29 21:57:05 'cause that sensor is supposed to have a 10mV/Degrees C output, so that would imply a very low temperature if the sensor were working properly. Jun 29 21:57:20 goge: BTW, I won't bet my head on that but if you connect some high-impedance sensors to some ADCs that require low impedance inputs, problems may arise Jun 29 21:59:06 goge: also, the higher clock frequency, the more noise. Jun 29 21:59:55 8-bit AVRs almost don't have the noise problem, while I had lots of noise with the same input on a 168 MHz microcontroller board, and that's with properly designed analog section Jun 29 22:01:21 BBB -> 12-bit ADC over 1.8V range -> 0.44mV per bit -> a reading of 25 Degrees C should give an output of ~568 bits Jun 29 22:02:37 Oh whoops, the TMP36 outputs 750mV at 25C, which would be a reading of ~1706 bits Jun 29 22:03:10 goge: as I've seen PDF the sensor could be loaded with current up to 250uA, from another side it can give values up to 2V, which is too much for analog input of am335x Jun 29 22:03:40 goge: what kind of interfacing do you use to connect output of sensor to analog inputs? Jun 29 22:04:38 kfoltman: I've programmed once DSPs up to 160MHz and with properly designed analog section the noise RMS value is under 5mV easily Jun 29 22:06:31 "I flipped it around for giggles and the bbb shut off" -> sadly might not have been such a hot idea Jun 29 22:07:54 t-szczyrba: in this particular case, the problem is the flash prefetch in the MCU - problems (if any) may depend on a particular chip/board anyway; generally, high clock -> more likely to get digital noise Jun 29 22:08:40 kfoltman: but the noise in case of temperature measurement shouldn't be a problem if any kind of filtering was used Jun 29 22:09:32 t-szczyrba: yes, that's why it's typical to do median filtering or something similar on ADC inputs Jun 29 22:09:58 even some application notes from microcontroller manufacturers recommend that (might or might not apply to full SoCs like Sitara) Jun 29 22:15:16 moring Jun 29 22:18:21 I ahve a request for CCO, but doubt it will get listedn to. Jun 29 22:18:36 i wished the serial header plug just was'tn installed Jun 29 22:18:39 :-( Jun 29 22:19:05 once you stick capes on your bbb, you cant' access it Jun 29 22:23:40 would be easy enough to remove and be able to access from below Jun 29 22:24:37 or replace with an angled connector? Jun 29 22:25:13 angled could work Jun 29 22:25:35 or make your cape have a female header on the bottom and provide it on the cape somewhere Jun 29 22:42:59 ssi, yes. it could be Jun 29 22:43:13 but, it just was'nt well thought out Jun 29 23:47:55 emeb_mac if your here, do you have any advise for first running the blank canavs cape? I just finished checking my assembly of one, and going to power it for the first time once I get a better handle on your software for it Jun 29 23:48:51 magyarm: I'd recommend power it w/ 5V via some jumpers and measure current draw first time Jun 29 23:49:27 should be < 100ma (probably much less) Jun 29 23:49:51 then plug it into a BB and boot - shouldn't interfere with booting. Jun 29 23:50:09 emeb_mac will do that, but won't it try to read the blank emmc? my thought was that I should flash the emmc first Jun 29 23:50:29 emmc? no emmc on the BCC board. Jun 29 23:50:42 i'm sorry, was thinking eeprom Jun 29 23:50:53 the EEPROM and Flash can both be blank w/o hurting anything Jun 29 23:51:11 awesome Jun 29 23:51:22 thank you Jun 29 23:51:41 run i2cdetect to see that the EEPROM and port expander show up. Jun 29 23:56:15 will do. just have to take it apart. got over eager and stacked to my *bone already Jun 29 23:58:50 hey emeb_mac Jun 29 23:59:27 hey mrpackethead Jun 29 23:59:38 i've ust got my two bbb's and capes back online Jun 29 23:59:49 and was about to ask the same question Jun 30 00:00:25 NB, when i buidl the next one, i'll do shot by shot build instructions Jun 30 00:01:19 that'll be helpful Jun 30 00:05:34 eric, whic i2c bus will it be sitting on Jun 30 00:08:18 mrpackethead: depends on which BB you have Jun 30 00:08:25 BBB Jun 30 00:10:16 I don't remember - try either bus 2 or 3 Jun 30 00:10:36 you should see something at 0x38 Jun 30 00:10:43 that's the port expander Jun 30 00:10:56 root@bbb-one:~# i2cdetect -l Jun 30 00:10:57 i2c-0 i2c OMAP I2C adapter I2C adapter Jun 30 00:10:57
