**** BEGIN LOGGING AT Mon Feb 29 02:59:59 2016 Feb 29 05:55:18 Good morning\night =) Feb 29 06:12:48 good $timeofday to you too Feb 29 06:14:56 $timeofday = early Feb 29 07:54:01 hello everyone, I am the beginner of bbb and have to image porcessing with it.please suggest me any good camera which dont create any compatability issues in future. I have to do camera interfacing through uart ports. Feb 29 08:09:02 hello Feb 29 12:49:20 ? Feb 29 13:06:03 So I just finished my BBB USB 4 Port hub and sent of for prototype PCB's http://imgur.com/a/AtpfX Feb 29 13:06:37 Its designed to make the USB of the BBB more relaible and be more compact/tidy than an external hub or cape solution. Feb 29 13:06:57 Its also designed to not block any cape or the HDMI/SDCard sockets. Feb 29 13:07:24 I am guessing 2 weeks for getting boards back and then i have to populate them for testing. Feb 29 13:13:52 You will see on the pictures there are 2 mounting holes. These match the mounting holes on the BBB and are there to provide structural rigidity to the Hub, it just doesn't hang off the USB port and hope for the best. Feb 29 13:25:06 Strontium: that's pretty cool :) Feb 29 13:25:34 bradfa: Thanks. Feb 29 13:25:48 Strontium: how does the design prevent the user from plugging it in upside down and shorting out the 5V to ground inside the BBB USB type B port? Feb 29 13:26:19 bradfa: It doesn't. Except for the fact the board is exactly the same size as the BBB. Feb 29 13:26:45 Its not a board for dummies. The user would need to decide if they power it externally or use the BBB 5V on the USB. Feb 29 13:27:06 Strontium: I applaud you but I hope you have plans to educate the dummies, there are many of them :) Feb 29 13:27:45 bradfa: I can put a piece of kapton tape over the Shield pad on the connector. That would prevent it. Then they would have to remove that, Feb 29 13:28:03 Strontium: that's a good idea, I suggest you do that before you send any out to any dummies :) Feb 29 13:28:11 But seriously its the same size and shape as the BBB, it would be wierd to plug it in upside down. Feb 29 13:28:24 But i see the point. Feb 29 13:28:37 Strontium: you are giving BBB buyers much too much credit for their intelligence and you will get returns if you do not prevent people from being stupid Feb 29 13:29:26 Well, it wont power up unless the end user expcitly installs jumpers on the board (with a soldering iron) or wires up a 5V supply. Feb 29 13:29:41 Strontium: ah, ok, well that'll help too :) Feb 29 13:29:47 I will explain how to do that and its super easy. But it will require a small amount of skill to install. Feb 29 13:30:13 Strontium: if you make it so people don't have to solder but that it comes with a default config that just works, more people will be inclined to buy it if you plan to sell some Feb 29 13:30:29 In fact, you can wire up to the 5V on the BBB Cape connector and get all the power you need. Feb 29 13:31:04 bradfa: I can default it to run from the BBB 5V on the USB but its limited to 500ma Feb 29 13:31:47 Alternatively I can have people tell me what "mode" they want. And i can do the jumper for them. Feb 29 13:31:56 I haven't thought that far yet. Feb 29 13:46:49 What is the difference between "omap3-sgx-modules" and "omapdrm-pvr" recipes when building an image using yocto? Feb 29 13:48:25 Strontium: did you do the design in Altium? Feb 29 13:48:58 bradfa: Nope, Kicad all the way. Feb 29 13:49:21 Strontium: oh nice! :) Feb 29 13:49:41 Strontium: I hope you are successful, it seems like a very useful board you designed :) Feb 29 13:49:46 I think Kicad is awesome. Feb 29 13:50:12 bradfa: Thanks, i will hang out here anyway and post updates as they happen. Im not much of a blogger Feb 29 13:51:02 I got some really good hints on BBB Usb hardware here from zmatt Feb 29 14:00:03 :) Feb 29 14:25:30 hi Feb 29 14:46:41 Hi guys, I have simple question to prove myself :D If I know I am going to contiuously read from driver, I should open the device and than read in the loop right? Not open, read, close and process and than again right? Because I have already seen the code when someone put for(;;) loop and inside is opening reading and closing file all the time Feb 29 14:55:34 generally speaking, closing and reopening never makes sense Feb 29 14:55:46 what device? Feb 29 15:01:51 zmatt: reading quite a lot of data from FPGA Feb 29 15:02:03 zmatt: linux kernel Feb 29 15:02:55 zmatt: for me too and I would put opening out of the reading loop but I wanted to be sure I am not loosing common sense :D Feb 29 16:09:16 Looking for some support, hoping someone can help Feb 29 16:13:21 Running Beaglebone Black Rev C, Kernel 4.1.18-bone, trying to read/write MCASP configuration registers but having no luck. Tried using devmem2 and also tried reading using the PRU. I've used the PRU and devmem2 to prove that I can read a different memory location correctly, but can't read MCASP. Feb 29 17:07:46 hi Feb 29 17:07:53 Feb 29 17:08:51 we are facing some problem with ds18b20 temperature sensor & beaglebone black Feb 29 17:10:51 ? Feb 29 17:14:20 lol that's nice :D Feb 29 17:15:08 at least we all know about it now Feb 29 21:09:04 Bruce__: is the McASP module you're trying to access enabled? Feb 29 21:11:54 (in PRCM) Feb 29 21:18:02 what dtb file isload on boot ? anyone can explain me please or give a link for understand that Feb 29 22:22:25 hey, does anyone have experience with setting/forcing screen resolutions in archlinux arm? Feb 29 22:22:29 specifically for the beaglebone black Feb 29 22:23:55 sonant: tried kernel cmdline ? Feb 29 22:27:42 not yet! Feb 29 22:27:43 thank you! Feb 29 22:37:39 sonant: should be lots of examples around Feb 29 22:40:21 i tried one of them Feb 29 22:40:24 probably need to put it in your uEnv.txt Feb 29 22:40:38 mounting a modified file over the /proc/cmdline Feb 29 22:41:18 i have a line in uEnv.txt to set the resolution, per some example on some forum(tm), but it did not work either Feb 29 22:41:38 i'll look more for an answer from that angle Feb 29 22:41:54 are you sure that is getting correctly read in .. ie. does it match when you cat /proc/cmdline ? Feb 29 22:42:07 or dmesg|head Feb 29 22:42:35 dmesg should give you a clue if the syntax is wrong or the mode unavailable Feb 29 22:43:09 i'll check the dmesg, because cat /proc/cmdline did not return my modified version Feb 29 22:43:17 aha :) Feb 29 22:44:07 double-chcek you're editing the right one .. I've known there be two in different places Feb 29 22:51:41 the changes aren't sticking Feb 29 22:51:53 i'll have to look at uEnv.txt Feb 29 23:05:42 uEnv.txt appears to have little to no extant documentation- anywhere Feb 29 23:06:09 examples are a good place to start, you're right Feb 29 23:23:10 that doesn't appear to work either Feb 29 23:23:14 this is a good challenge, though Feb 29 23:23:29 thanks for your advice vermemit :) Feb 29 23:41:38 hi, can anyone help me fin a minimal debian jessie image for the BBB? Feb 29 23:43:45 altazor08: like a console only image? Feb 29 23:43:54 yes Feb 29 23:44:11 just minimal debian with ssh Feb 29 23:44:22 http://elinux.org/Beagleboard:BeagleBoneBlack_Debian Feb 29 23:44:35 no desktop enviroment and no bonescript Feb 29 23:46:30 you could use debian-installer to install whatever size image you want Feb 29 23:47:32 can i get a hint into taht pleasE? Feb 29 23:50:00 so, if the image is "testing" will it be updatef from the repos? Feb 29 23:50:18 just apt update upgrade for latest? Feb 29 23:52:05 altazor08: once you install with your choices, yes Feb 29 23:52:51 altazor08: or install a prebuilt image and apt-get remove what you don't want Feb 29 23:56:54 well thanks Feb 29 23:57:52 altazor08: http://ftp.us.debian.org/debian/dists/jessie/main/installer-armhf/current/images/netboot/SD-card-images/ Feb 29 23:58:20 altazor08: i never did fix a bug in the installer, so there is some manual tweaks you need to do from the commandline Mar 01 00:00:11 altazor08: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=782574#87 Mar 01 00:00:39 vagrantc is that for the debianinstall? Mar 01 00:01:44 altazor08: that's to use the debian-installer for jessie Mar 01 00:01:50 altazor08: you'll need a serial console Mar 01 00:02:31 if you were up for trying testing, those images should work out of the box. Mar 01 00:02:49 debian/stretch ... although it's a work in progress ... Mar 01 00:05:38 thanks a lot, I think I'll get one of the console prebuilt images for the bbb Mar 01 00:06:24 sure **** ENDING LOGGING AT Tue Mar 01 02:59:58 2016
