**** BEGIN LOGGING AT Sun Jan 26 02:59:59 2014 Jan 26 03:01:33 ah i see, it uses a library that hides the underlying i2c part though.. SCL and SDA of BBB (p9_19 and p9_20 if you are set up to work with this example) get connected in series with the SCL and SDA of both of your devices Jan 26 03:02:26 as you can see in tsl2561.py, smbus is the underlying library used Jan 26 03:03:25 if you’re using python, this library is more general and really easy to work with for i2c: http://learn.adafruit.com/setting-up-io-python-library-on-beaglebone-black/i2c Jan 26 03:04:47 and i2ctools are good to do testing from the command line Jan 26 03:08:53 johnwalkr: have you used the i2c bonescript library? Jan 26 03:09:33 no i haven’t Jan 26 03:09:43 i’m using that adafruit i2c library and sometimes smbus Jan 26 03:10:22 looking at a bonescript example.. Jan 26 03:10:40 looks like i can implement it that way too Jan 26 03:11:05 if you get your device working with the command line tools i2cset and i2cget, you will see how to implement it with bonescript easily Jan 26 03:11:24 sweet thanks for the tip Jan 26 03:12:52 im planning on converting that ts python to js Jan 26 11:55:05 I want to update the U-Boot on an Devkit8000 (Similar to a BeagleBoard) and therefor i started with building X-Loader and U-boot. the X-Loader that is compiled does not work and differs is size (~17KiB) with a pre-compiled (~42KiB) one I found. Everywhere I search for information it only tells that there are 3 compile commands an 1 time signing has to be done. Anybody knows what is missing? (http://pastebin.com/sURpmCLd) Jan 26 12:53:11 <_av500_> netlynx: you dont need to sign anything Jan 26 12:53:15 <_av500_> I thinlk Jan 26 12:56:42 _av500_, signing is done automatically if 'make CROSS_COMPILE=arm-linux-gnueabi- ift' is used. But neither works. Jan 26 13:22:45 hi guys Jan 26 13:23:16 i just got my beagle bone yesterday and its awesome to play with :) Jan 26 13:24:12 just waiting on my lcd cpe and then i want to buy a wifi and bluetooth cape and sound cape then run android on it but one thing im not sure of is if there is a battery cape of any sort or escription? Jan 26 13:31:02 beagleboneuser, must it be a mobile android system? Jan 26 13:32:32 im looking at the posbility of making my own tablet Jan 26 13:33:10 I think there are display capes with audio codecs Jan 26 13:33:20 wifi is probably better over USB Jan 26 13:33:28 http://www.tigal.com/product/3526 Jan 26 13:33:43 problem with many of the display capes is their poor general support Jan 26 13:34:01 unless they are CCO, they usually come with one working setup and that's it Jan 26 13:34:27 cool thanks Jan 26 13:41:08 hey thanks netlynx that looks cool Jan 26 13:42:13 so it would be better in your opinion tbr to use a wifi usb dongle with powred hub Jan 26 13:42:15 beagleboneuser, is combines a few of your requirements, but lacks the battery part. I have seen it working. Jan 26 13:43:14 the PMIC itself can deal with LiPoly batteries IIRC Jan 26 13:43:40 well this is all slightly new to me i come from a background of software development and home made gadgets with an arduino ( including my own mobile phone that i use daily) Jan 26 13:44:15 ahh i had forgoten it has its own pm ic Jan 26 13:56:33 I think someone wrote how to modify the board and software to make it work with a battery Jan 26 13:58:30 i just found a battery cape but it uses AA batteries and im looking more for a flat lipo battery :) Jan 26 14:12:03 av500, problem solved. The latest U-boot also generates a MLO file. There is no need to compile one separately using X-loader sources. The U-Boot MLO files is the size of the precompiled ones. And it boots now. Jan 26 14:13:33 hi, I'm new to beagle board. I'm having a beagle board xm and a windows pc. I have putty and vnc viewer installed. But I dont know how can I get IP address of the board. Please help me . Jan 26 14:16:26 you could just connect to it over the serial port Jan 26 14:17:53 I did it and got an IP adress. But when I tried with Putty, it was failing to connect and was inactive. Jan 26 14:20:24 check if there is anything listening to port 22 Jan 26 14:21:17 i conected over serial and then used ifconfig to get the ip Jan 26 14:22:00 I know I should know this but I can't figure it out. how to enable the sd card as secondary storage ? I think I need some virtual devicetree stuff or u-boot foo but can't figure it out Jan 26 14:22:17 and http://elinux.org/Beagleboard:MicroSD_As_Extra_Storage doesnt really explain anything Jan 26 14:22:37 wasn't that supposed to work on recent angstrom? Jan 26 14:22:45 beagleboneuser: check with netstat Jan 26 14:24:18 I want to understand how to fix it (not end up in angstrom update hell :P) Jan 26 14:24:50 if i couldnt figure out how to connect via serial then netstat would have been my next idea :) Jan 26 14:27:45 I will try #archlinux-arm Jan 26 14:28:48 nice i just came across a discusion detailing the adding of audio without useing the cape Jan 26 14:41:45 i want to use espeak on bbb . can any one plz help me ? Jan 26 14:47:40 sefat: and your problem is? Jan 26 14:50:21 problem is i can install espeak by "opkg install espeak" and it installs on bbb. but when i type on the command prompt ' espeak "say something" . it produces no sound with no error. ' Jan 26 14:51:32 what shuld i do . i want to use text to speech on bbb. Jan 26 14:52:40 well, what do you have connected to your BBB? Jan 26 14:53:36 a usb -> audio converter and it works perfectly with pocket sphinx. Jan 26 14:54:24 well, have you checked which audio device espeak tries to use? Jan 26 14:55:04 hm x11vnc doesnt like m lol Jan 26 14:55:10 me* Jan 26 14:55:15 nope . how can i check it ? i dont know the process. Jan 26 14:58:30 sefat: well I don't know espeak either, you might want to look if there is an espeak community that could help you with this Jan 26 14:59:50 thank u tbr. i'll try to communicate with them . Jan 26 15:01:42 cool seems like x11vnc is now working lol# Jan 26 15:15:12 any macbook pro mavericks users in the channel today? Have some issues with writing a new Angrstom image to my sdcard. Jan 26 15:16:55 iitgrad: yes! what are you doing exacly (on terminal) ? Jan 26 15:17:38 df -h 3471 sudo dd bs=1m if=/Users/kevinmcquown/Downloads/Angstrom-Cloud9-IDE-GNOME-eglibc-ipk-v2012.12-beaglebone-2013.06.20.img of=/dev/disk2s1 Jan 26 15:17:50 ignore the 3471 Jan 26 15:18:23 the result i get is this: Jan 26 15:18:47 I guess it needs to be either /dev/disk2 or /dev/rdisk2. But be sure to unmount it using Disk Utility (or just umount) Jan 26 15:19:15 3724+0 records in 3724+0 records out 3904897024 bytes transferred in 2459.711570 secs (1587543 bytes/sec) Jan 26 15:19:35 yes, I unmount it first. actually it appears you have to because if you don't I get an error saying that the device is in use Jan 26 15:19:54 were you following a tutorial or sth? Jan 26 15:20:18 ok just try using disk2 instead of disk2s1 Jan 26 15:21:07 gotcha, I'll give that a try. and yes, I'm using a tutorial, I've look at several on line and they all pretty much say to do the same thing Jan 26 15:21:28 the only real difference I can see is that most all mac tutorials weren't using mavericks Jan 26 15:21:46 and many refer to a usb card reader which I don't use since my macbook pro already has a slot for the sd card Jan 26 15:22:01 so I am wondering if that might be the issue Jan 26 15:22:35 mavericks is fine, no difference at all for these tools. Jan 26 15:23:07 strange, slot is connected to usb bus internally, but I don't they are mentioning that :D Jan 26 15:23:22 great, also I notice that whenever I put the card back into my mac I get an error saying the "the disk you inserted was not readable by this computer" Jan 26 15:23:27 but anyway only other problem might be this, and you need to be *careful* Jan 26 15:23:47 you need to make sure disk2 is MMC Jan 26 15:23:55 yes i will :-) Jan 26 15:23:57 I mean, it is usually on macbooks Jan 26 15:24:05 (on mine, it's always disk2) Jan 26 15:24:31 so when I put the card in I always erase it first using disk utility Jan 26 15:24:52 you don't need to, because dd already overwrites everything, Jan 26 15:25:08 starting from block 0, means will overwrite even the partition table on the disk Jan 26 15:25:23 ah ok, so no partition format information like ms-dos (fat) is relevant Jan 26 15:25:38 can you share your tutorials url? (to be sure) Jan 26 15:26:15 say, image usually is complete raw disk image, having 2 partitions, that's why you need to load it in to disk2 instead of disk2s1 etc. Jan 26 15:26:45 replace 'say' with 'yes' :D strange typo Jan 26 15:27:18 gotcha, well it is off writing to disk2 so I'll report back in about 45 minutes :-) Thanks for all the help!! Jan 26 15:27:32 good luck :) Jan 26 15:37:50 whoami Jan 26 15:54:30 <_av500_> notme Jan 26 16:00:05 whats the easiest way, once ssh'ed into the bbb to tell what version of angstrom it is running? Jan 26 16:01:12 iitgrad: uname -a that's the kernel version Jan 26 16:01:23 sweet, gratzie Jan 26 16:02:22 it might also have something like debian, cat /etc/issue (not sure if it's gonna work) Jan 26 16:02:23 getting my BBB is really going to ramp up my knowledge of linux and apparently node.js, python, etc. never heard of cloud9 before now.

I checked google and it says xserver-xorg-xvfb but odpkg says its unknown? Jan 26 20:25:44 opkg * Jan 26 21:02:48 names Jan 26 21:03:17 ? Jan 26 21:05:35 <_av500_> opkg update Jan 26 21:05:40 <_av500_> http://stackoverflow.com/questions/17528691/headless-x11-angstrom Jan 26 21:06:12 has angstrom website been rebuilt yet? last I heard it was down Jan 26 21:06:15 <_av500_> https://www.mail-archive.com/angstrom-distro-devel@linuxtogo.org/msg06568.html Jan 26 21:07:22 <_av500_> looks like you need to build it yourself Jan 26 21:07:29 <_av500_> unless it was added Jan 26 21:07:56 thanks _av500_ Jan 26 22:00:02 I cut the D+/D- lines and it powered up... hmm.. Jan 26 22:00:21 is there a newer binary for xM?: I seem to have Angstrom 2010.7-test-20110220 beagleboard ttyS2 Jan 26 22:06:21 hi, I'm a long time linux user who got excited about interfacing with the "real world" using the beaglebone black. Unfortunately, I don't know very much about the "real world", by which I mean: circuits. Jan 26 22:06:34 as a learning project, I thought it would be fun to hack open the controller of a remote controlled car and use the bone to operate the car. Jan 26 22:06:49 the controller uses switches - I thought that they'd be potentiometers, but no, this particular toy is full-speed-only Jan 26 22:07:05 So, I'm thinking that I could just use a transistor or a relay or something to let the bone control the switches. This is where I feel confused. Jan 26 22:07:17 the toy controller runs on 9V. There seems to be about a 5V drop between the two sides of each switch. Jan 26 22:07:42 seems like someone who really understood transistors might be able to hook the bone to this thing and make it work... but that's definitely not me Jan 26 22:08:16 relays seem simpler because they keep the two circuits separate, but just shopping for relays is daunting to me Jan 26 22:09:13 they seem focused on high voltage applications, I barely need any increase at all. Jan 26 22:09:42 and then I can't tell if the 3.3 V from a GPIO pin would be enough to activate a relay. Jan 26 22:09:57 Any guidance? Jan 26 22:11:42 there are ready made relay systems with conetion guides for both the beaglebone and rasbery pi aswell as a lot of ones for the arduino Jan 26 22:13:55 something like this? https://www.tindie.com/products/SierraFoxtrot/quad-relay-output-cape-for-the-beaglebone-black-and-white/ Jan 26 22:16:29 something like that would do but for your purposes its overkill Jan 26 22:16:35 may i pm you? Jan 26 22:17:10 sure, and thanks for your help! Jan 27 00:43:43 Hi Jan 27 00:47:07 How can I add a custom screen to my projecft? **** ENDING LOGGING AT Mon Jan 27 03:00:00 2014
