**** BEGIN LOGGING AT Wed May 04 02:59:58 2016 May 04 05:00:43 just curios, does the linux os compromises with the code efficiency, to make code more readable and understandable ? or, given the availability of powerful hardware, its irrelevant? May 04 05:01:14 *curious May 04 05:09:45 no May 04 05:09:58 it favors long term maintainability May 04 05:10:05 Linux runs on high end and low end hardware May 04 05:10:17 say a lowly cortex-m3 May 04 05:10:28 or even the old ARM7TDMI w/MMU May 04 05:18:09 is there an eMMC flaher image that only flashes u-boot? May 04 05:18:47 heck, i'm confused. where does uboot reside on the beaglebone black? im assuming its on the emmc but is there an extra EEPROM or something i'm missing? May 04 05:19:00 the u-boot i have on here now does not have a 'env save' option which i'm trying to get May 04 06:23:40 ds2: okay, so very little, insignificant, efficiency is lost in the process of making it maintainable ? May 04 06:24:19 jkridner, any news on beagle-blue yet!? :P May 04 06:24:27 no May 04 06:24:32 :'( May 04 06:24:42 yeah, distractions. :( May 04 06:24:51 jkridner, did anythnig come of the arduino tie-up ever? May 04 06:24:59 I wake up every day thinking this is the day I'll share the design and.. May 04 06:25:11 ??? May 04 06:25:15 beaglebone blue?! May 04 06:25:20 was ist das May 04 06:25:24 or is that still plagued by arduino-vs-arduino lol May 04 06:25:26 http://beagleboard.org/blue May 04 06:25:34 stt_michael: tre? May 04 06:25:36 jkridner: ping May 04 06:25:41 oic May 04 06:25:47 jkridner: do you need anything address-wise? May 04 06:25:50 for Blue, at least I'm the only one in the way. May 04 06:25:53 oops May 04 06:25:56 av500: time. May 04 06:25:57 damn, i thought it was going to be bbb but with an ARMv8 chip on it May 04 06:26:00 av500: sanity. May 04 06:26:06 jkridner, http://www.arduino.cc/en/Main/ArduinoBoardTre May 04 06:26:08 wrt shipments May 04 06:27:02 * jkridner wishes av500 had a .org credit card and would just buy the junk and be done with it. :-) May 04 06:27:06 I fully imagine the Tre might have been shelved ... May 04 06:27:31 but .. you do get a bit tired of the "new fun stuff ... Soon(tm)" May 04 06:28:18 * jkridner is working at 2:30am... I know it sucks. not sure how to get the trust level just to share the github. May 04 06:28:42 * jkridner wants help, not politics. May 04 06:28:57 * jkridner wants to not point fingers. May 04 06:29:00 * stt_michael started at 10pm .. its just gone 7:30am .. stop whining .. May 04 06:29:05 :D May 04 06:29:18 oh and I haven't eaten since I started :p May 04 06:29:20 ofc. May 04 06:29:32 * jkridner kicks... ;) May 04 06:29:33 * stt_michael loves his job .. no, really .. May 04 06:29:43 -sigh- May 04 06:30:07 spose I should get back tot he solder bench .. afk a few :p May 04 06:30:27 I love mine too and my life, but it would be nice to get something done and not feel constantly reminded of what isn't done. If I could just get this problem, then the next one... May 04 06:30:46 currently, I'm debugging 2 wifi issues on precursor boards to the Blue. May 04 06:31:35 One design, wifi works fine, but there are some crazinesses with connman vs. the world. May 04 06:32:09 on the other, wifi doesn't work and no idea why... just changes to the mmc2 pins used as far as design differences from what I can tell. May 04 06:32:36 I mean, http://dev.ti.com/pinmux doesn't complain.... so why won't it work? May 04 06:33:18 the second design is the way I *want* to integrate the wifi on the Blue. May 04 07:11:07 designing stuff can suck sometimes... like we had a dsp prototype board we lovingly called the "gas pipe" for its -50 dBFS noise floor :P May 04 07:11:46 hi, I have a question about BBBs UART peripherals May 04 07:12:35 then perhaps ask it May 04 07:13:07 from Debian, I set the baud rate for a port at 2500000 (2.5Mbps), and I get around 2.0Mbps May 04 07:13:12 which is OK May 04 07:13:43 but when I use more ports simultaneously, the speeds splits May 04 07:14:06 is this normal? May 04 07:15:58 (the command I use to set that baudrate is "stty -F /dev/ttyO1 " May 04 07:16:12 might be driver inefficiency May 04 07:16:56 I'm pretty sure it's nowhere near the interconnect bottleneck yet May 04 07:18:33 are there any custom BB serial drivers available? May 04 07:20:00 well there is another driver in the kernel actually, but I don't know whether it's any faster May 04 07:20:24 you'd have to recompile the kernel to compare May 04 07:20:42 another alternative would be to access the uarts directly from userspace, bypassing the kernel May 04 07:22:52 how do I accomplish the second alternative? can you please give me some documentation? May 04 07:26:29 it's not really easy, and there's really a serious lack of examples of this technique May 04 07:26:51 I've started on an example from python ( https://github.com/mvduin/py-uio ) although for performance it would be better to use C/C++ obviously May 04 07:27:45 the UARTs themselves are documented in the AM335x TRM, although they have a pretty awful register interface and I disagree with the initialization procedure given in the TRM May 04 07:32:18 thanks May 04 08:14:53 can I use bbb with ubuntu and 7" lcd with touch? May 04 08:15:25 I follow here for installing May 04 08:15:27 https://blog.guh.guru/tech/crosscompile-qt-5-2-1-for-bbb/ May 04 08:26:53 screnn not responding May 04 08:28:20 my lcd link http://www.seeedstudio.com/depot/images/product/7LCD%20Cape.jpg May 04 09:04:55 hhe: I tried to use the 7'' lcd with bbb debian Whezzy. It didn't work. But, now I use it with update Debian Jessie on http://elinux.org/Beagleboard:BeagleBoneBlack_Debian May 04 09:05:21 hhe: Why did you choose Ubuntu ? May 04 09:08:32 I saw this https://blog.guh.guru/tech/crosscompile-qt-5-2-1-for-bbb/ tutorial so I chose ubuntu May 04 09:09:18 I want to use qtserialport with ubuntu May 04 09:09:40 with angstrom I haven't install serial port May 04 09:22:02 hhe: I had very good look at that tutorial and it looked like they build lfs image rather than ubuntu May 04 09:22:23 but then again tl;dr; so i might be wrong May 04 09:23:43 yeah i was wrong May 04 09:23:55 it indeed used ubuntu image May 04 09:24:34 also kinda curious what kind of person would choose ubuntu and why รต.O May 04 09:27:42 Ionakka I want to use qtserialport I did n't install on Angstrom so I want to look ubuntu May 04 09:31:18 hhe: do you have reason why you want to build it yourself? May 04 09:31:35 rather than installing libqt5serialport5-dev in your cross-compilation environment? May 04 09:34:01 I am no reason using ubuntu. I want to use qt5 and qtserialport. So I only saw this tutorial May 04 09:34:13 then I used ubuntu. May 04 09:35:08 there is explain how to cross compile etc. etc May 04 09:35:29 I did not install qt5 on Angsrom May 04 09:37:38 Ionnakka what am I do know? May 04 09:39:24 am I use Debian? May 04 09:48:55 hhe: if you just want to _use_ it, you need compilation environment (either cross-compilation or gcc & friends installed in your beagle) with the headers that come from -dev package and runtime package installed on target where you want to run your applications May 04 09:49:20 if you compile things on beagle you should be able to just # apt-get install libqt5serialport5-dev May 04 09:49:21 there May 04 09:49:35 that should work both on debian and on ubuntu May 04 09:51:03 also, if you're looking at setting up cross-compilation environment yourself, I'd recommend to take a look at https://github.com/beagleboard/image-builder May 04 09:51:15 (the image building scripts that build the official images) May 04 09:51:59 (then again, the cross-compilation environment is dependant on the actual target distribution etc) May 04 09:54:38 ok thanks May 04 10:25:11 is debian support 7" LCD touch 4DCAPE-70T? May 04 10:36:47 https://groups.google.com/forum/#!topic/beagleboard/p4fr4Avrr-Y looks like one year ago one had to do bit extra to get it working with official debian/jessie images but afaik should work nowdays and should be fast to test with the official bbb debian/jessie images available @ http://beagleboard.org/latest-images May 04 11:27:29 bgamari: hi there, isnt this early for you May 04 11:27:30 ? May 04 12:01:44 citylight2, I live in Germany now May 04 12:04:16 and working there? May 04 12:31:51 Hi, are there a difference between EHRPWM and ECAPPWM ? May 04 12:33:28 In reference manual, I understand that ecappwm are accessible via pru and ehrpwm aren't, am I right ? May 04 12:55:02 dirkk: PRUSS has an additional instance of eCAP, but the PRU cores can also access any peripheral outside PRUSS (but with higher and more unpredictable latency) May 04 12:56:17 eCAP is primarily designed for capturing (timestamping) pulses or transitions, although it can also be configured as a basic PWM output. eHRPWM is designed solely for PWM and has more eleborate features May 04 13:14:37 zmatt: ok thanks May 04 15:48:30 * zmatt sighs at Tero Kristo May 04 20:04:41 My Micro SD card hasn't been working ever. I just looked at the soldering for the card reader. May 04 20:05:35 It looks as if the pins on the reader on the side where the usb connector is, are soldered together. May 04 20:06:55 There are four pins on each side of the reader. Where can I find documentation of which of these 8 pins corresponds to the 8 connectors connecting to the card? May 04 20:09:38 The board is element14 rev c. If that matters. May 04 20:18:15 A small correction. The four pins close the micro HDMI going to the micro SD card reader are soldered together. May 04 21:18:34 So I suspect that this photo shows the problem https://www.solidfiles.com/v/n5dGBMXQQwBpQ May 04 21:19:37 Anyone with a multi meter and a bbb at hand, that could check which pins on the micro sd corresponds with these four pins on my reader? May 05 01:34:41 hi all May 05 01:38:18 hey steve May 05 01:41:01 Finally fired up my BB black after having it for over 2 years :( May 05 01:44:03 welcome to the club May 05 01:44:25 I couldn't wait to start mine up, surprised you waited so long May 05 01:44:31 it's one of my favorite pieces of tech May 05 01:47:39 I had it out initially, but got sidetracket May 05 01:47:51 had issues on osx May 05 01:48:28 what issues? May 05 01:48:50 can't seem to connect via usb May 05 01:49:03 hmmm... how did you solve it? May 05 01:49:15 keep running into mac folks and donno what magic is needed May 05 01:49:30 thats what I am trying to figure out now, have an hour or so spare May 05 01:52:09 whats your favourite use for your BB? May 05 01:53:24 custom portable devices May 05 01:53:40 brb - rebooting May 05 01:55:04 I got it for some home automation projects initially but right now, I have it set up as a low power home server May 05 02:02:54 I did the same thing May 05 02:06:04 yeah it's surprisingly capable May 05 02:06:44 not the best use since it's not taking advantage of the GPIO/capes but I'm hoping to get a BB enhanced eventually to get back into that May 05 02:06:49 back May 05 02:12:50 0 capes over here May 05 02:18:49 that was what drew me in over other SBCs May 05 02:19:09 plus the hardware is completely open and transparent May 05 02:19:24 also the Beagle is a nicer mascot than a raspberry May 05 02:49:52 SBC? May 05 02:50:05 single board computer May 05 02:59:00 haha wait how is that different than a regular pc May 05 02:59:19 okay okay i can see where ur coming from with the whole SBC thing **** ENDING LOGGING AT Thu May 05 02:59:58 2016
