**** BEGIN LOGGING AT Fri Dec 05 02:59:58 2014 Dec 05 05:31:50 hey Dec 05 05:32:49 I am an electronics engineering student and want to get acquainted with embedded system development Dec 05 05:33:42 I am thinking of getting a beagleboard and want to ask whether it is the right tool for a newbie ? Dec 05 05:34:10 I have experience with C, but none with Linux and other open source tools Dec 05 05:50:12 hi. anyone available ? Dec 05 05:50:49 w00t. my BBB just arrived Dec 05 05:51:14 saharsh93, google for example code, I haven't found any shortage of it. Dec 05 05:51:46 Is BBB a good tool for newbies to embedded systems ? Dec 05 05:51:56 not sure Dec 05 05:52:07 id say probably more so w/ Debian being the default Dec 05 05:52:17 have you looked at the raspberry pi b+? Dec 05 05:52:37 nfi if its better/worse or not but has a pretty mature community and tools behind it now and lower $$ iirc Dec 05 05:52:38 I have benn comparing both BBB and raspberry pi Dec 05 05:53:02 i have a 1st gen model B to compare w/ Dec 05 05:53:13 And found BBB to be more appealing but it lacks support Dec 05 05:53:26 tbth if you want to learn linux any old box will do Dec 05 05:53:42 x86 has the widest support Dec 05 05:53:51 and probably less "gotcha" moments Dec 05 05:53:55 The BBB does have the benefit of having very easily accessible documentation by not using a BCM CPU. Dec 05 05:54:01 RPi has blocked me from following them on twitter Dec 05 05:54:14 wow, lame Dec 05 05:54:29 I am on a blacklist Dec 05 05:54:38 just the one? Dec 05 05:54:47 well. probably all of them Dec 05 05:54:56 I'm a controversial figure Dec 05 05:55:01 this looks neat http://blog.imgtec.com/powervr/mips-creator-ci20-development-board-now-available Dec 05 05:55:19 I want to see people try it before i invest Dec 05 05:55:30 Mmmm, the oddness that is MIPS. Dec 05 05:55:47 meh Dec 05 05:55:58 bbb is arm, most people have an x86 desktop / laptop Dec 05 05:56:20 Yeah I want start with an ARM Dec 05 05:56:24 cool little board for $65 Dec 05 05:56:38 runs android and linux, i don't care how it does it Dec 05 05:57:15 my little ADSL2 PCI card has some mips linux running on it Dec 05 05:57:55 danube or some such iirc Dec 05 05:58:03 what i want to know is why isn't the damn board just a rectangle Dec 05 05:58:15 that wld be boring Dec 05 05:58:16 things sticking out all over... Dec 05 05:58:16 Does anyone have any links to webpages for beginners ? Dec 05 05:58:33 As in a guide to starting with BBB ? Dec 05 05:58:43 there's one on the bbb itself Dec 05 05:59:11 enough to learn to blink things anyway Dec 05 06:00:10 hmmm....any other resource beyond that ? Dec 05 06:02:43 books :D Dec 05 07:12:12 any one has tested am335x timer0 as interrupt in linux ? Dec 05 07:13:00 if any one done please let me know Dec 05 11:17:55 hello, Should I disable the HDMI cape if I want use a TFT LCD ? Dec 05 11:30:05 Tick: yes Dec 05 11:30:37 And after that, I need to write a DTO or by default it's good ? Dec 05 11:46:40 hey, I have purchased a standard FTDI USB to Serial breakout board to be able to interact with u-Boot on my BBBlack. I have been unable to elicit any kind of response with minicom or screen. I am using openSuse 13.2, and I am confused as to whether or not I need any external (install on-demand) Drivers for the device. this confusion arises from my understanding of the mentality behind the default linux kernel being one of "It should have the Bigg Dec 05 11:46:42 est possible amount of compatibility by default" Dec 05 11:49:03 DJHenjin: does the ftdi work if you test loopback? Dec 05 11:49:24 DJHenjin: did you connect TX to RX and RX to TX as it needs to be? Dec 05 11:49:33 DJHenjin: is it 5V or 3.3V? Dec 05 11:49:50 tbr I am actually quite new to interfacing with hardware devices,even though i have been programming for a while Dec 05 11:49:58 /dev/ttyUSB0 exist ? Dec 05 11:50:21 I have not done any hardware based troubleshooting as of yet, /dev/ttyUSB0 Does indeed exhist Dec 05 11:50:39 try putty Dec 05 11:50:58 5v 3.3 selectable via jumper Dec 05 11:51:07 make sure it's set to 3.3V Dec 05 11:51:26 was the first thing i did Dec 05 11:51:33 You only need to connect the ground and RX/TX Dec 05 11:51:34 detach it from the BBB and connect RX to TX Dec 05 11:51:56 then try if you can get echoed back what you type in the terminal emulator Dec 05 11:54:29 I do indeed get typed input being echo'd back in terminal emulator Dec 05 11:58:18 DJHenjin: good, then that's working Dec 05 11:58:51 DJHenjin: now connect RX on the FTDI to TX on the BBB and vice versa Dec 05 12:01:28 pins 2&&3&&6 of j1 correct? Dec 05 12:02:41 sth like that, don't have the srm at hand Dec 05 12:04:45 k, i just have to perform a crude sex change on a couple male cables Dec 05 12:14:19 no such luck Dec 05 12:29:40 there, got it Dec 05 12:37:33 Thank You! So very much guys! Dec 05 12:42:38 Where is uEnv.txt in the last debian image ? :/ I want to disable HDMI Cape, but there is no uEnv.txt on the mounted partition Dec 05 12:43:44 Tick: /boot Dec 05 12:43:47 should be there Dec 05 12:45:12 Yes, I tried, but when I reboot, it is rewrite Dec 05 12:45:49 DJHenjin: glad you got it working. :) Dec 05 12:47:42 as an aside, It should be made easier to find information on the website Dec 05 12:49:09 It works now Oo Dec 05 12:55:32 (but the screen is white) :( Dec 05 14:50:44 I disable the HDMI DT, but my LCD screen still white, any idea ? :( Dec 05 14:52:18 what color do you want? Dec 05 14:54:14 I want using my LCD like a screen Dec 05 14:54:27 with desktop or terminal :/ Dec 05 15:58:14 Mornin' all. Is anyone familiar with the BB's process when performing a reboot triggered by a "shutdown -r"? I have a process that is exhibiting strange behavior only after rebooting the BB via this method. Dec 05 15:59:29 This is using Deb running of off the eMMC. Dec 05 18:24:31 hi Dec 05 18:24:53 i see no /devttyS4, why is there no uart4 on bbb? Dec 05 18:31:57 uart4 would be ttyS3 and you might need to configure it in devicetree Dec 05 18:32:07 hmm Dec 05 18:32:15 so adafruit documentation is wrong Dec 05 18:32:22 but im not seeing it in device tree Dec 05 18:33:29 echo ADAFRUIT-UART4 > /sys/devices/bone_capemgr.9/slots Dec 05 18:33:39 -bash: echo: write error: File exists Dec 05 18:37:03 whats going on? Dec 05 18:37:18 uh looks like they renumbered them, so uart4 is ttyS4 Dec 05 18:37:27 uhm...ttyO4 of course Dec 05 18:37:36 im in the shit then Dec 05 18:37:40 i need UART4 Dec 05 18:37:56 did you try /dev/ttyO4? Dec 05 18:38:03 it doesnt exist Dec 05 18:38:11 im trying to create it at the moment Dec 05 18:38:15 but no luck so far Dec 05 18:38:29 read scroll back ^ Dec 05 18:39:57 uh oh Dec 05 18:39:59 Message from syslogd@beaglebone at Dec 5 18:39:28 ...

Dec 05 18:47:00 I thought they did away with ttyS in favor of ttyO when they went to the high speed serial drivers Dec 05 18:48:43 yeah other dts files work ok Dec 05 18:48:51 its something to do with my changes Dec 05 18:49:24 do i need to reboot? Dec 05 18:52:40 i thought pyBIBO would make it easier to deal with serial stuff. no?

Dec 05 20:03:05 maybe thee github repo is still updated? Dec 05 20:04:25 I found their nightly repo, but their is no "plug and play" image, you must compile the kernel etc ... :/ Dec 05 20:04:33 https://github.com/Angstrom-distribution Dec 05 20:05:05 ah, 'k dunno if they still distribute images or not :/ Dec 05 20:06:19 free beer at 7AM? great idea!

Dec 05 21:09:55 I just flashed and I'm on wheezy Dec 05 21:10:32 It's you... ;) Dec 05 21:10:48 Maybe I missed my flash but everything seems clean Dec 05 21:11:45 the md5sum still matches on the server side.. it was jessie when i uploaded it on Nov 20th. ;) Dec 05 21:13:19 Ok :) Dec 05 21:13:31 rcn-ee: thx for merging Dec 05 21:14:17 vvu, not a problem.. if it's useful i merge. ;) Dec 05 21:15:03 true, this saves me a good work of patching to your omap builder Dec 05 21:16:47 also can you say how long does it take to make a rootfs on a wanboard or smth like that ? Dec 05 21:17:00 on my qemu machine it takes ~10 mins with my local mirror Dec 05 21:17:45 vvu, 1hr 15mins: http://rcn-ee.homeip.net:8080/job/github_omap-image-builder/lastSuccessfulBuild/ Dec 05 21:18:18 cannot read, missing read permissions :) Dec 05 21:18:24 Apparently it's my sdcard who is dead, it stay in Read Only mode :/ Dec 05 21:18:28 it just ran: export apt_proxy=apt-proxy:3142/ ./RootStock-NG.sh -c bb.org-debian-stable-4gb Dec 05 21:18:51 vvu, jenkins musta changed something, that use to be world-readable.... Dec 05 21:19:08 :( Dec 05 21:20:44 vvu, how about now (i have github oauth managing it) http://rcn-ee.homeip.net:8080/job/github_omap-image-builder/lastSuccessfulBuild/ Dec 05 21:21:00 same Dec 05 21:21:07 ungureanuvladvictor is missing the Overall/Read permission Dec 05 21:21:31 yep can read now Dec 05 21:23:43 it should help give you an idea.. that's also on the older boudary devices i.mx6 (only 1gb of ram) but still sata harddrive.. Dec 05 21:25:04 yep, so i am in good case 10 mins with a fair amount of packages :) Dec 05 21:25:16 Tick, try: rebooting, different usb-flash adapter, etc.. Dec 05 21:25:23 still have sata harddrive, want to change to an ssd Dec 05 21:25:25 yeap, 10mins is pretty quick fo rit.. Dec 05 21:25:26 yep Dec 05 21:28:54 I found the problem, my "dd" line was wrong :( Dec 05 21:29:11 hopefully you didn't take out your main drive.. Dec 05 21:30:25 I swaped if= and of= :o Dec 05 21:30:40 So I dump my SD card with Wheezy inside Dec 05 21:30:42 Genius Dec 05 21:31:39 You backed it up. ;) Dec 05 21:36:09 Hey Dec 05 21:36:56 How can i write a GUI ? Dec 05 21:38:07 etch a sketch's work great.. Dec 05 21:42:42 not the correct answer? perhaps the all steps and code is what he wanted ;) Dec 05 21:43:14 rcn-ee: hi dude Dec 05 21:43:17 dunno the question itself was fairly ambiguous Dec 05 21:44:16 darn he left.. i had a good follow with play doo.. or that magic goop! Dec 05 21:44:25 hehee Dec 05 21:44:56 golly, i googled his query and what a load of info Dec 05 21:45:25 totally ambiguous... ;) Dec 05 21:45:27 probably too much unrelated stuff, based on the question that was actually asked Dec 05 21:45:46 thurgood_: dont be so serious on a friday ;) Dec 05 21:46:11 lol, I'm feeling checked out with another nearly 2 hours to go Dec 05 21:46:27 or we should have pointed him to io.js as that's the fork of the week.. ;) Dec 05 21:46:52 webapp 4tw Dec 05 21:47:56 is io.js related to node somehow... other than language of choice? Dec 05 21:48:28 it's a fork of node.js by node.js top 4-5 developers... they got tired of dealing with the company sponsoring node.js.. Dec 05 21:48:55 ah.. just found that out on the googles Dec 05 21:53:23 One day I set out to learn how to make GUIs... Dec 05 21:53:38 Eighteen hours later, I completed my first webapp :\ Dec 05 21:53:59 <_av500_> gee, old people here Dec 05 21:56:29 I've just been getting into JavaScript after spending most my life using Perl. Dec 05 21:56:39 I feel like I've been released from a prison I never knew I was in. Dec 05 22:04:56 my first gui was in ass'y with some C thrown in for a video card demo. Dec 05 22:05:10 1992 Dec 05 22:05:39 And I'm being called old :p Dec 05 22:06:40 Well truthfully my gui dev goes back into the 80's Dec 05 22:08:14 <_av500_> zyamada: nope, not calling you old Dec 05 22:11:01 Oh thank goodness. I am having difficulties letting go of my youth. Dec 05 22:11:34 we live in our youth forever. Gets us into lots of trouble but so what. Dec 05 22:16:23 <_av500_> +1 Dec 05 22:23:45 kids today! Dec 05 22:23:48 * plaw eyerolls Dec 05 22:23:53 :-P Dec 05 22:30:39 i avoided gui dev for most of my life because, yuck. but now enjoying it using clojurescript and om Dec 05 22:35:08 get gooey with gui? Dec 05 22:58:08 I'm a little disappointed with the 3.14 kernel, What replaces the device tree? Dec 05 23:04:50 it is a "device tree" if you want 3.8 and capemgr just: sudo apt-get update ; sudo apt-get install linux-image-3.8.13-bone68 ; sudo reboot Dec 05 23:05:34 goodnight Dec 05 23:10:25 rcn-ee, ok thx ! Dec 05 23:10:47 What changes in 3.14 ? Apparently it's the kernel who makes the job Dec 05 23:16:31 rcn-ee: ooh seeing you're here, thanks for all your beagle foo! Just wanted to say that 'in person' :) Dec 05 23:22:47 rcn-ee, I have installed nothing and my BBB is already full :| Dec 05 23:54:03 halp Dec 05 23:54:32 usr0 - 3 are blinking in sync with a patern like "blink-blink-pause" Dec 05 23:55:54 should i hit it with a hammer? Dec 05 23:56:15 ya, i think i'll do that. **** ENDING LOGGING AT Sat Dec 06 03:00:00 2014
