**** BEGIN LOGGING AT Sun Mar 23 02:59:58 2014 Mar 23 04:38:35 hi i am new to beaglebone black... i have a 5v 5A power supply, and can i power up beaglebone black with it? Mar 23 04:40:02 ruka: assuming the polarity is correct, you sure can Mar 23 04:42:41 Dan1 : Thank you a lot.. and is it true that power supply should be center positive one? Mar 23 04:42:53 that im not sure Mar 23 04:44:14 but as long as the voltage is correct and you have enough amps (i think something like 0.7a is min) your ok with that side of it, im currently using a 5V 2A but if its more amps it still only uses as many amps as it needs.... you cant make it use extra amps it dosnt need Mar 23 04:46:25 you can ground gpios to use more power Mar 23 06:16:51 hi i once shutdown the OS of beaglebone black.. but when i power up again power light plus all user leds lit for about 30sec and all getting power off why is that? Mar 23 06:22:37 do you get the network and serial interfaces during that time? Mar 23 07:16:42 hello..noob questiom here..is there any link that compares the features of raspberry pi and beaglebone? Mar 23 07:19:28 have you tried asking the search engine of your least distrust? **** BEGIN LOGGING AT Sun Mar 23 10:06:03 2014 Mar 23 14:16:29 Hello, I have been using the BB for a while now, and am interested in helping more directly with the open-source side of things. So, I was wondering where a good place to start would be. Mar 23 14:52:39 hi guys. I need some help. Do I need to connect my arduino to a logic level converter to have the bbb use it as a slave device? Mar 23 14:53:07 and could i also power the beaglebone black through a 5v output on the arduino? Mar 23 15:44:07 delux247, it depends on which arduino board you want to use. Mar 23 15:48:17 Depending on your time frame, the "coming soon" Tre may be what you want as well Mar 23 15:48:18 http://arduino.cc/en/Main/ArduinoBoardTre Mar 23 16:07:19 Hi, I was trying to emulate a BBB using QEMU but i can't find a suitable image Mar 23 16:07:37 is there a Newbies guide for building an image or a prebuilt image ? Mar 23 16:07:57 NG300: as i know for BBB there is no image that works in qemu Mar 23 16:08:02 there is for BBxM Mar 23 16:08:51 mmm can i trust that a binary run on BBxM will run on BBB ? Mar 23 16:08:58 nop Mar 23 16:09:01 different SoC Mar 23 16:09:54 mmm very bad ok thanks is there a guide on building an image in general ? Mar 23 16:48:36 i have got another question. I have my beaglebone black being powered by my arduino nano's ioshield which gets its power from a lipo knocked down to 5volts. I now want to communicate through i2c with that being said the logic level converter I have, https://www.sparkfun.com/products/11978, has power and ground. with the arduino powering the bbb do i still need to connect power and ground on the logic level cnverter? Mar 23 16:52:54 deluxe247: GND is common over arduino, llc, bbb Mar 23 16:53:19 deluxe247: arduino Vcc needs to be connected to llc HV Mar 23 16:53:26 you have a truk, a sedan and a bicycle. with the bicycle being washed and clean, the sedan fully fuled up, do you still need to fuel the sedan? Mar 23 16:53:28 deluxe247: bbb Vcc needs to be connected to llc LV Mar 23 16:54:01 deluxe247: assuming LV is lower voltage, and HV is higher voltage, and that arduino is 5V and bbb is 3V3 Mar 23 16:54:56 mazzanet, exactly wanted to confirm that what i was doing is correct. burned up an arduino nano this weekend already and do not want to damage to my bbb Mar 23 16:56:45 mazzoo, exactly wanted to confirm that what i was doing is correct. burned up an arduino nano this weekend already and do not want to damage to my bbb Mar 23 16:56:55 sent my last message to the wrong person Mar 23 18:31:23 hello beagleboarders Mar 23 18:32:48 just connected my beagleboard black to my win laptop...is there an easy way to upgrade the angrstrom os without using a micro sd card since i dont have one at the moment Mar 23 19:27:58 hi Mar 23 19:28:30 can the usb client port be used as a host port on the beaglebone black Mar 23 19:29:47 <_av500_> pauljbl: yes, with some soldering Mar 23 19:29:53 <_av500_> somebody did that, see google Mar 23 19:30:10 pauljbl: see here: http://beagleboard.org/Support/FAQ#usb Mar 23 19:30:36 is that for the beaglebone black Mar 23 19:32:42 is there a limit on number of devices attached to a beaglebone black Mar 23 19:33:32 pauljbl: as long as you have usb-hubs I don't think there is Mar 23 19:33:36 <_av500_> 128 Mar 23 19:36:22 is that soldering for the beaglbone black? Mar 23 19:36:36 <_av500_> yes Mar 23 19:36:56 cant find it do you have link to it Mar 23 19:37:34 <_av500_> http://pansenti.wordpress.com/2013/05/27/beaglebone-black-with-two-usb-host-ports-it-can-be-done-but-its-not-easy/ Mar 23 19:37:37 <_av500_> its gone Mar 23 19:37:40 <_av500_> try google cache Mar 23 19:38:08 <_av500_> also: https://groups.google.com/forum/#!topic/beagleboard/Mbaa5tsdfOk Mar 23 19:38:09 it can be done without modifying the board. if you either splice in the 5V or use a HUB to supply the 5V Mar 23 19:38:33 <_av500_> you still need to tell the hub there are 5V I guess Mar 23 19:38:46 d+/d- will "just work" Mar 23 19:38:52 <_av500_> ah Mar 23 19:39:09 so if i connect a hub to the client port it will just work Mar 23 19:39:23 remember the meeting room displays built on gen7? they were like that :D Mar 23 19:40:02 pauljbl2: it needs to be a powered hub AND you need to tell the kernel that it's a host port not a device Mar 23 19:40:27 how do i tell the kernel that Mar 23 19:41:06 the aforementioned links cover that Mar 23 19:43:31 ok, seems you need to modify something on the board to kick it into action Mar 23 19:44:23 the mailing list discussion covers that Mar 23 19:47:09 does flashing the eMMC on the BBB deteriorate it or is that pretty negligible unless someone is doing it very frequently? Mar 23 19:50:50 neglibible Mar 23 19:51:19 running on it writes logs etc much more frequently Mar 23 19:51:51 thanks Mar 23 20:42:27 <_Aqua> heya, has anyone any experience with the ssd1963 based lcd panels and the BBB? Mar 23 20:52:32 So I'm using the rcn-ee debian image on http://elinux.org/BeagleBoardDebian#Debian_Stable_.28wheezy.29. I tried changing the user_password.list file to make it start with a different username/password but it didn't work. debian:temppwd still works. Anyone know what's happening / how to fix it? Mar 23 21:46:58 granito-laptop, to change your password, just do "passwd" in terminal Mar 23 21:47:09 you will be prompted for your current password and then you can enter a new one Mar 23 21:47:40 you can change the user ID from "debian" too if you want, or you can just create a new user with a new password Mar 23 22:06:24 hi guys i need some help. I have my arduino connected through i2c to my beaglebone black and am pretty lost on how to write to it through i2c. I am hoping to do this through c++ as well. I am able to detect the device on the i2c bus as well Mar 23 22:24:12 <_Aqua> so when I plug my 5" lcd panel w/ P8.28 to the pclck on my lcd the BBB won't boot. If the plug pclck into a general IO it boots. What could be the problem? Mar 23 22:26:27 is the panel meant for the BBB or the BBW? Mar 23 22:27:58 <_Aqua> probably not either, it's not on a cape. just a ssd1963 based lcd. pin's are all set correctly other than the p8.28 issue, linux tilcdc finds it and initializes it, although it's not giving me a console. Mar 23 22:30:47 ah, no idea then Mar 23 22:37:42 can anyone point me to a good tutorial on using i2c with the beaglebone black. I have my arduino setup to receive data through i2c but am unsure of how to send data through the beaglebone black. Mar 23 22:38:01 or is there a library that facilitates this. i also am doing this in c/c++ Mar 23 22:55:29 PurpleDog, how do I change the user ID? The workaround I found was creating a new user with a different password then going back and deleting the debian user. Not exactly the most straightforward path :/ Mar 23 22:58:41 granito-laptop, usermod -l new_name old_name I believe Mar 23 23:27:39 sweet! that worked. Thanks! Mar 23 23:38:51 I have been beating my head against a wall. can someone show me how to write to an i2c device connected to my beaglebone black? I have my arduino connected through i2c and just need to send it instructions/values from the beaglebone black. I am trying to do this through c++ and have not found any good examples. Mar 23 23:42:42 deluxe247: what have you tried so far? Mar 23 23:44:17 systemG3102, well i have been tying to figure out how to send the letter f through the command line using i2cset that way i could at least validate ive got things setup right. from there I would go througha and code Mar 23 23:45:16 systemG3102, my device has an address of 0x2a, set by me, and when i do i2cdump it returns 0x00. I just am unsure of how to send f for forward or b for back to the device Mar 23 23:56:43 deluxe247: do you have anything else you could try, another i2c device in your parts bin like a rtc or RAM or something? Mar 23 23:57:23 i have a gy80 ten dof which i know was detected fine and I was able to dump values fine Mar 24 02:01:55 what does it mean when all 4 LEDs in the BBB are flashing while trying to re-flash the eMMC? Mar 24 02:04:31 wait til it finishes :p Mar 24 02:05:47 I mean they are all flashing in unison like a heartbeat - I don't remember this happening before Mar 24 02:06:39 hmm Mar 24 02:06:51 my board was somehow bricked after I ran an os update so now I'm trying to re-flash, and it looks like it's failing Mar 24 02:06:57 4 on steady is finished .. could be error or somehow broken Mar 24 02:07:09 might be RMA time ... ;) Mar 24 02:09:33 very strange, all I did was install the debian image and update, then it wouldn't boot up again Mar 24 02:11:04 what are you flashing currently? the angstrom image? Mar 24 02:12:46 trying to reflash the debian image from the beaglebone website Mar 24 02:13:05 hmm never used that one .. I use Rob Nelsons from eewiki.net Mar 24 02:13:07 it ran fine for days without any issues Mar 24 02:24:02 PurpleDog: try flashing with angstroms just to confirm whats going on? im running debian from the micro sd fine at the moment on mine Mar 24 02:24:34 i did have it flashed to the emmc as well but will be using the much bigger sd card i have Mar 24 02:25:10 I guess I'll have to try that Dan1, I'm trying to reflash the eMMC again with debian and now it's just taking much longer than I remember Mar 24 02:25:28 yea it did take AGES reflashing Mar 24 02:25:40 the first time I flashed, it took ~10 minutes Mar 24 02:25:46 i forget how long.... but it was a "start it and come back in an hour" sort of thing Mar 24 02:25:53 oh wow Mar 24 02:25:58 nah mine was WAY longer than 10 mins Mar 24 02:26:33 well I will give this another hour then try the angstrom image Mar 24 02:26:41 just let it go and go back and have a look in like an hours time.... Mar 24 02:27:12 yeah I'll just go say a prayer for the little beagle Mar 24 02:27:26 yea then if nothing happens maybe the image you have is broken or something, try running the SD version of debian or the flasher version of amgstroms Mar 24 02:28:40 if it actually ends up working, I'm scared of attempting another package update Mar 24 02:28:52 haha Mar 24 02:28:54 nah dont be Mar 24 02:29:02 mine updated fine last nite Mar 24 02:29:25 some times it does break tho..... so if your setups that important make sure you have regular backups :) Mar 24 02:29:47 im still in teh "playing" mode.... so im happy to break it and set it up again from scratch Mar 24 02:30:08 I have been using debian on a BB C4 for years and have never had a dist-upgrade break anything Mar 24 02:30:32 it gets heavy use as an IRC client and NTP server heh Mar 24 02:30:33 yeah I just got this a few days ago, finally had time to play with it today but as you can, even a full re-flash failed the first time Mar 24 02:30:50 can see* Mar 24 02:48:31 is there a c library available for i2c on the beaglebone black or is there a good tutorial for using i2c on the bbb using c/c++? **** ENDING LOGGING AT Mon Mar 24 02:59:59 2014
