Jul 07 05:51:00 *ARM7 i believe Jul 07 05:51:50 andif i recall correctly the pi is hard float Jul 07 06:27:41 flufmnstr, no they are nto the same architecture Jul 07 06:27:48 they are both Arm processors Jul 07 06:32:00 hey eric Jul 07 07:20:27 <_Sy_> hello Jul 07 09:05:37 * mranostay is back Jul 07 09:12:30 * _av500_ hides Jul 07 09:15:28 mranostay: why are you back Jul 07 09:15:39 didnt we kill you off properly last time.

I just hate hate Jul 07 09:32:53 kfoltman: thing is i get fired i have a year of living expenses unlike most americans Jul 07 09:33:25 mranostay: that's not bad, well, relatively Jul 07 09:34:17 aaaa\ Jul 07 09:34:24 <_av500_> bbbb/ Jul 07 09:34:34 lol Jul 07 09:34:58 yeah sleeping now Jul 07 09:35:01 can any body tell me how to use "analogRead"? Jul 07 09:35:50 <_av500_> sorry, I cannot Jul 07 09:35:51 I'm using the example on the BBB getting started website and all I get is "null" Jul 07 09:35:53 <_av500_> I am all digital Jul 07 09:37:35 ok Mr. digital.. I have another Q for u, How can I control PWM with bonescript in cloud9? Jul 07 09:37:36 digital is just a special case of analog Jul 07 09:37:50 or vice versa Jul 07 09:38:12 dm8tbr: only at low enough frequencys Jul 07 09:38:48 I'm applying 0-1.8 DC voltage Jul 07 09:39:14 <_av500_> aa____: sorry, never used bonescript Jul 07 09:39:30 and all I get NULL.. (and I checked the it is connected to the right pin) Jul 07 09:42:35 bonescript is part of that random angerstrum thing Jul 07 09:43:04 angostura? makes you bitter Jul 07 09:43:14 get a real os Jul 07 09:43:24 write some scripts in python Jul 07 09:43:25 :-) Jul 07 09:43:57 aa____: i'm sure that the instructions are in the wiki somewhere Jul 07 10:06:47 whats the difference between pin numbers and pin names? im having trouble googling up a stright answer Jul 07 10:08:12 <_av500_> its what your name is vs where you live Jul 07 10:11:38 ok. now how does that apply to setting up pins? Jul 07 10:14:30 _av500: you're assuming houses all have numbers Jul 07 10:38:02 Is there a distributor (BeagleBone Black) for the South East Asia region? Singapore-based perhaps? Jul 07 10:52:02 quit Jul 07 10:52:11 bye Jul 07 11:29:20 <_av500_> SpeedEvil: and not all pins have names Jul 07 12:28:27 dang it. all of a sudden AdaFruit_BBIO seems to have forgotten the setup command Jul 07 13:12:55 <_Sy_> hello Jul 07 13:28:00 hi ! Jul 07 13:29:08 I am really new in beaglebone world, but I want to add support for bbk in buildroot Jul 07 13:29:22 But I can't use vanillia kernel :/ Jul 07 13:29:57 Do you have any plans to merge minimal DT support for kernel 3.11 ?? Jul 07 13:32:45 Because I can't use the system use in beaglebone's github without some crappy hacks :/ Jul 07 13:44:13 is there no beaglebone kernel git repository that you could simply clone from? do you really have to patch the kernel? Jul 07 13:44:53 honestly I never understood why people need self written buildscripts in order to build a patched kernel. Jul 07 13:45:39 (and I do not mean buildroot) Jul 07 13:45:57 I don't need to writen my own buildscripts, but I want to add support in buildroot Jul 07 13:46:21 And I need either to use vanillia or a remote repo Jul 07 13:46:32 Additionally I can use some patches Jul 07 13:47:27 So I could use patches given in beaglebone repo, but I can't get remote patches in buildroot :/ Jul 07 13:47:40 personally i would create a git repository for that. fork from mainline linux and add patches that i need. and then i would use that repository for buildroot. Jul 07 13:48:15 simply create a github linux fork Jul 07 13:48:53 Yes, but it is a little overkill no ? Jul 07 13:49:34 And I don't think a system like that will be merged in buildroot :/ Jul 07 13:50:49 why? you only tell buildroot to use the git repository from you instead of the vanilla. Jul 07 13:51:37 it is a much better solution than taking vanilla an applying patches on it like for instance robert nelson does with his kernel build scripts Jul 07 13:51:56 i mean patch files. Jul 07 13:54:12 and if you want to submit a defconfig for bbk to buildroot than you could leave out the kernel as well if that would be easier. Jul 07 14:14:16 For now I think I will apply only one patch (which add basic device tree support) to try bbk without any device like pwm, i2c, etc. Jul 07 14:14:38 I add more chance to see that merged soon Jul 07 14:15:12 And once support will be added in vanilla kernel, I will removed this patch Jul 07 14:16:28 Do you think this one is enough : https://github.com/beagleboard/kernel/blob/3.8/patches/capebus/0005-beaglebone-create-a-shared-dtsi-for-beaglebone-based.patch Jul 07 14:18:17 (and than you for your answers :) ) Jul 07 14:18:28 Hello everybody. Can anyone recommend a small usb-Hub that works with the BBB? The ones on the following page are either way to big or impossible to find in my country: http://circuitco.com/support/index.php?title=BeagleBone_Black_Accessories#USB_HUBS Jul 07 15:36:21 thorsten_: just get a cheap one Jul 07 15:39:13 Humpelstilzchen: Everything I tried so far failed miserably, even some less cheap ones. Jul 07 15:40:45 thorsten_: I tried both, they both worked Jul 07 15:46:06 Humpelstilzchen: tried both of what? Jul 07 15:47:26 sorry tried two hubs Jul 07 15:50:10 Humpelstilzchen: Which brand did you try? With a brand-name maybe I can find them in my country (The "Inland"-Hubs on the page are impossible to find with google here, it could only be worse if the brand was called something like "The" :( ) Jul 07 16:04:07 <_av500_> thorsten_: booting with the hub attached? Jul 07 16:04:11 <_av500_> is the hub self powered? Jul 07 16:06:23 self-powdered Jul 07 16:15:54 _av500_: I can boot with a hub attached, but as soon as the hub get's a device attached it ceases to work Jul 07 16:16:47 _av500_: Hubs: Tried self powered ones as well as passive ones. Jul 07 16:21:48 thorsten_: try to attach your device to the hub before you boot Jul 07 16:24:45 Humpelstilzchen: Doing this has the effect, that the Hub blinks once to show it's active, during boot, then it shut's down and I can't get it to work any more. Jul 07 16:25:23 I think my hubs may be just incompatible Jul 07 16:29:16 hi guys Jul 07 16:29:36 i just learned that flash memory dies after a certain number of write/erase cycles Jul 07 16:29:50 Humpelstilzchen: I think my hubs may be just incompatible, so I search for some hub that someone knows to work with a BBB (And I can actually find in onlyshops near me so I don't have to spend 30$ for shipping) Jul 07 16:29:58 where can i find specs on the beagleboard black's flash Jul 07 16:30:00 ? Jul 07 16:30:03 Hi deller Jul 07 16:35:01 anyone know how many cycles the EMMC on the beagle black is rated for? Jul 07 16:45:24 deller: basically the same as any standard sd card Jul 07 16:46:17 ive been told like 10k absolute max Jul 07 16:46:34 is this about right? Jul 07 16:46:46 how about the flash on phones Jul 07 16:46:59 no way it dies after 10k writes Jul 07 16:49:38 Remember that's 10k (if the number is right) to every byte/block on the flash and then maybe that byte/block gets removed from the active list Jul 07 16:49:49 it's not like 10k writes to anywhere on the flash and the whole flash becomes unusable. Jul 07 16:50:00 10k was normal in 2006, according to wikipedia micron says 1000k and: this is not for the whole flash, but for a single block. Jul 07 16:50:59 can i use it for regular storage? like logs and video captures? Jul 07 16:51:03 or should i use the SD for that? Jul 07 16:51:07 If you're concerned about it, though, boot off an SD card, then you can replace the SD in the unlikely event the flash dies while you're still using the board. Jul 07 16:51:23 im not worried about that Jul 07 16:51:37 im worried about slow boot times off DF Jul 07 16:51:39 SD* Jul 07 16:51:52 heard 30s+ from SD Jul 07 16:52:49 I use a SD to boot debian. Usually I can get to access the system with ssh after 5-10 seconds. Jul 07 16:57:20 and through serial? Jul 07 16:57:32 tty console? Jul 07 17:02:58 No clue, for the tty-console. Currently I have no serial cable. Jul 07 17:31:26 deller: I think i was a bit to enthusiastic it's more like 20 seconds Jul 07 17:35:40 one thing I like about weekends....less backlog to plow thru :P Jul 07 17:38:31 heh Jul 07 17:45:55 mourning Jul 07 17:48:45 mornin ka6sox Jul 07 17:49:47 it is indeed mourning Jul 07 17:52:55 * dm8tbr mourns the end of the weekend Jul 07 17:53:02 oh wait I'm on vacation... Jul 07 17:58:52 he he Jul 07 18:00:43 <_av500_> hoho Jul 07 18:00:47 * kfoltman wasted all his weekend on IRC Jul 07 18:03:12 _av500_, no more ho ho's Jul 07 18:03:18 they died with twinkies Jul 07 18:03:35 <_av500_> I wish I spoke Chinese: The the bile before class finished board package 12AT7 in JADIS version (including tube + transformers) Jul 07 18:03:57 ka6sox: twinkies are back! Jul 07 18:04:39 12AT7 dual Triode, 12v filaments Jul 07 18:04:41 (on 07-15) Jul 07 18:04:48 emeb_mac, whut? Jul 07 18:04:53 http://www.theatlanticwire.com/business/2013/06/great-twinkie-drought-ends-july-15/66517/ Jul 07 18:04:59 did Bimbo buy them? Jul 07 18:05:36 <_av500_> ka6sox: what 12at7 is I do know Jul 07 18:05:44 <_av500_> what the bile before class is Jul 07 18:05:46 <_av500_> not sure Jul 07 18:05:56 <_av500_> outside of a high scholl context Jul 07 18:06:00 <_av500_> school Jul 07 18:06:03 gotta go now - l8rs Jul 07 18:06:11 p00f Jul 07 18:06:55 _av500_, dunno... Jul 07 18:07:04 maybe thats "Best in Class" Jul 07 18:07:15 iirc 12AT7's were the top gain Jul 07 18:07:27 or was that 12AX7's that were...gotta look Jul 07 18:07:57 <_av500_> ax7 Jul 07 18:08:08 <_av500_> at7 is the low output impedance Jul 07 18:08:46 12AX7 is Av=100 Jul 07 18:08:49 <_av500_> yes Jul 07 18:08:55 12AT7 Av=60 Jul 07 18:09:09 are you using them as cathode follower? Jul 07 18:11:44 <_av500_> ka6sox: nothing specicfic Jul 07 18:11:50 <_av500_> was just browsing aliexpress for tube stuff Jul 07 18:11:56 <_av500_> and came across the bile Jul 07 18:12:16 I see Jul 07 18:12:42 in on of the radars we used I use them as part of the PFN Jul 07 18:26:10 kfoltman: wasting weekend on irc? that is my job! :P Jul 07 18:26:47 heh Jul 07 18:39:07 <_Sy_> hello, anyone here? Jul 07 18:39:27 no Jul 07 18:39:28 no-one but trolls Jul 07 18:39:35 <_Sy_> :) Jul 07 18:39:44 <_Sy_> quiet at the weekends isn't it? Jul 07 18:41:04 <_Sy_> Just finished writing my floating IP manager, works really well, have two BBB's connected via two serial ports and ethernet....my PC connects to the cluster using a single IP, if either of the BBB's fails the floating IP transfers to the other. Jul 07 18:45:41 Trolls! in the channel....jsut thought you might want to know. Jul 07 18:46:37 <_Sy_> who, what, where ? :) Jul 07 18:46:45 _Sy_: how do you deal with systemd? :D Jul 07 18:47:05 <_Sy_> What is the problem with systemD? Jul 07 18:47:50 <_Sy_> Each BBB has a static IP and I add a 2nd IP to either system depending on which ever is promoted to be the master of the cluster. Jul 07 18:47:51 Well, I'm assuming that it starts some services that are meant to manage the network interfaces Jul 07 18:47:57 ah Jul 07 18:48:38 <_Sy_> It seems to work quite well. Jul 07 18:49:07 ok, so you can be relatively confident that your second IP address will not be bothered by any connection manager stuff? Jul 07 18:49:20 <_Sy_> The application itself is very small and written in Java...I then wrote a small library in C to manage the serial communications. Jul 07 18:49:55 <_Sy_> Doesn't appear to be....I've done only simple testing so far, a few niggles to iron out, but generally going very well. Jul 07 18:50:18 very small + written in java, probably not a good combo :) Jul 07 18:50:26 probably harmless though Jul 07 18:50:41 <_Sy_> Before assigning the IP I have a thread which attempts to connect on the floating IP, if it cannot reach the IP for 5 seconds then the slave promotes itself to master. Jul 07 18:51:45 ... and then the former master boots up ;) Jul 07 18:52:01 well, not "then", at the same moment Jul 07 18:52:11 <_Sy_> I have other apps also written in Java, like a modbus TCP driver which manages a connection to a mySQL database....with this new app, the modbus IO works with the datbase and the HA in mySQL handles the interface between the two slaves keeping everything in sync. my app allows 3rd parites to connect to the cluster. Jul 07 18:52:32 <_Sy_> Both are running all the time, but only one should have the floating IP. Jul 07 18:53:26 Well, I'm sure there are some potential race conditions, like if there's power outage and they both boot up at the same time. Jul 07 18:53:43 I do this with heartbeat and it switches between boxes seamlessly Jul 07 18:53:55 are you running Master-Master Replication? Jul 07 18:54:09 <_Sy_> They're should be a grace period where when they both come up they allow a period to check to prevent that happening. Jul 07 18:54:20 <_Sy_> Yes Jul 07 18:54:29 <_Sy_> Multi-Master replication on mySQL Jul 07 18:54:45 _Sy_: is that some daisy-chain configuration? Jul 07 18:54:57 1->2->1 Jul 07 18:55:04 circular replication Jul 07 18:55:50 <_Sy_> I couldn't get cronosync and heartbeat to work properly on the BBB....so in the end I wrote my own...mySQL only supports 2 masters, where they both sync to each other...at the present time you can't have more than 2 masters using mySQL without 3rd party add ons. Jul 07 18:57:44 <_Sy_> Does anyone know if they're is an echelon driver that works on Arm ? Jul 07 18:59:25 mdp: ping? Jul 07 19:00:00 <_Sy_> The configuration for my floating IP manager is extremly simple, in the cnf file you specify the serial devices to communicate on, the floating IP and your local MAC address, thats it. Jul 07 19:00:42 <_Sy_> The application sends the local IP to the remote and the app. compares the MAC addresses, whichever MAC is lowest is by default promoted to be the master. Jul 07 19:14:25 Are you expecting the MACs to change? Jul 07 19:17:33 echelon driver ? what is that ? Jul 07 19:20:07 rob_w, used by NSA to monitor your BBB Jul 07 19:20:14 j/k Jul 07 19:23:01 aiii Jul 07 19:23:29 prism won't fit :/ Jul 07 19:24:06 * rob_w activates his snowden_twitter_pusher Jul 07 19:25:38 So, when designing a cape, I know I need a EEPROM and a 2-bit DIP switch for address selection. However, the specified EEPROM has 3 address pins--which two should the switch be connected to? Jul 07 19:27:38 agmlego, 0 and 1 Jul 07 19:28:35 ka6sox: And A2 is tied high or low? Jul 07 19:28:39 pulled high Jul 07 19:28:44 OK, thanks. Jul 07 19:28:47 yw Jul 07 19:28:55 Is that in the SRM somewhere? Jul 07 19:29:57 agmlego, dunno, I just followed emeb's diagramme that works Jul 07 19:30:04 (and my cape uses that setup) Jul 07 19:30:47 OK, works for me. Jul 07 19:31:00 It does seem like the kind of thing that ought to be in the SRM though. Jul 07 19:31:10 (and it might be and I just was not able to find it). Jul 07 19:31:19 the BBB was designed to run standalone Jul 07 19:31:29 the Connectors are almost fully used. Jul 07 19:33:40 This is not a cape for the BBB. Jul 07 19:34:04 Well, I mean, it could be I guess, but it will be used on a white bone. Jul 07 19:34:28 right... Jul 07 19:34:34 both use same method Jul 07 19:34:42 Right. Jul 07 19:39:31 as long as your cape doesn't immediately come up and crash with the eMMC you should be okay Jul 07 23:46:53 Is this the best channel to discuss BB black? Jul 07 23:47:09 Probably. Jul 07 23:47:16 You could also try ##politics Jul 07 23:47:25 But they may shouta at you. Jul 07 23:47:40 Thank you for nor being helpful Jul 07 23:47:44 not Jul 07 23:47:54 How was that not helpful? Jul 07 23:48:11 It was certainly snide on top, but still conveyed the message. Jul 07 23:48:32 possible answers: YES or NO [with a goto] Jul 07 23:49:17 All right then - can the bb black be relfashed or booted from USB? Jul 07 23:49:27 reflashed, yes Jul 07 23:49:37 I'm told you can boot it from USB but haven't done it Jul 07 23:49:42 Do you have alink to a howto? Jul 07 23:49:56 does google not work where you are? Jul 07 23:49:56 i can't find one Jul 07 23:50:18 the debian/ubuntu ones Robert Nelson maintains Jul 07 23:50:29 there are others but I don't know of who maintains them. Jul 07 23:50:43 I am asking questions, either you know the answer or be quiet Jul 07 23:50:49 ... Jul 07 23:51:07 There are millions of robert nelsons Jul 07 23:51:39 BobCat: Nobody is being paid to answer your questions. Jul 07 23:51:46 Or, indeed, to be nice to you. Jul 07 23:51:46 BobCat, that attitude here is not appreciated Jul 07 23:52:00 And this is a public space, where you have no place to tell people to shut up. Jul 07 23:52:14 Thihi, I see nothing on flashing from USB there Jul 07 23:52:40 /ignore Bobcat Jul 07 23:53:12 You guys just don't know the answer, I understand Jul 07 23:54:40 Try to not be obnoxious Jul 07 23:56:19 Do you have a link to a howto flash from USB? Jul 07 23:56:49 You don't, and you're just being obnoxious, Jul 08 00:00:44 /c/c Jul 08 00:00:47 Hello, I've been playing with getting an audio DAC chip connected up to the BBB via I2S, and it works well. However, I think there is a bug, possibly in the driver.. There is no symptom, the audio sounds good. But, when I check with a scope, I see that the audio data is being clocked on rising edges of the bitclock (so that the DAC is therefore expected to read it on the falling edges of the Jul 08 00:00:47 bitclock). However, this is the opposite of what the I2S spec specifies. It is just luck that the audio plays. The data set-up time is being violated. Has anyone noticed this? I have a scope trace if anyone is interested. Jul 08 00:02:05 The I2S spec expects the data to be read on rising edges, as far as I can tell. This is the opposite to what I see on the scope. Jul 08 00:06:05 shabaz: sure it's not a _clock line? Jul 08 00:14:42 Hi SpeedEvil, according to the SRM doc, I don't think it is supposed to be inverted. So I'm wondering if the TDA19988 is mistakenly seeing this issue too. You're right that I can just insert an inverter onto the clock line, and all becomes well. But, I don't want to insert an inverter and then have a later build with the driver fixed :-) Jul 08 00:15:13 Hmm Jul 08 00:18:30 is there a general guide to pin muxing for the BBB? I know the pin number and the mode I want to set it to, but I'm having trouble finding the commands to actually mux the pin. Jul 08 00:19:04 Hello all! Jul 08 00:20:57 I deleted several megs worth of files from /lib/firmware, but df still reports 100% usage of /dev/mmcblk0p2 (eMMC) mounted as /. Why? Jul 08 00:44:30 Glorgnole, have you looked at https://github.com/bradfa/beaglebone_pinmux_tables and are they different from BBB? Jul 08 01:00:34 I need some help in running open cv v 2.4.5 on the bb-xm Jul 08 01:57:54 ello duckies **** ENDING LOGGING AT Mon Jul 08 02:59:59 2013
