**** BEGIN LOGGING AT Fri Jan 31 02:59:58 2014 Jan 31 03:09:44 Having a hard time getting a monitor for Beagle Bone black. have an old VGA out monitor but options from micro hdmi to VGA seem very expensive. Any advice Jan 31 03:10:10 RAMNAM: Should be about $30? Jan 31 03:10:11 <_av500_> ebay Jan 31 03:10:13 buy a new monitor?! Jan 31 03:10:17 <_av500_> get a cheap DVI Jan 31 03:10:28 hdmi -> dvi works Jan 31 03:10:38 forget vga withbeage Jan 31 03:10:40 bbb** Jan 31 03:11:27 if you get a uHDMI -> HDMI lead, and a HDMI->DVI adapter is what we did Jan 31 03:12:23 thankyou veremit and shadyman Jan 31 03:13:23 ok one option is surely a DVI monitor Jan 31 03:13:25 I'm working on a BBB Angstrom 3.8.13 trying to setup an EEPROM for a cape I've built and tested. Jan 31 03:13:42 I'm using this chip: http://www.parallax.com/product/602-00032 Jan 31 03:15:20 When I i2cdetect -y -r 1 I see the SCL and SCA on my oscilloscope. Jan 31 03:15:43 have you set default address lines .. one is permanently wired Jan 31 03:15:58 a2 Jan 31 03:15:58 cape eeproms are usualy in the 0x5y range Jan 31 03:16:31 for now I have a0, a1 and a2 tied high. Looking for it at 0x50 Jan 31 03:16:53 did you get the right i2c bus .. there are 3 on the beagle normally Jan 31 03:18:34 ll /sys/bus/i2c/devices Jan 31 03:18:49 i2c-1 -> ../../../devices/ocp.3/4819c000.i2c/i2c-1 Jan 31 03:19:18 P9 19, 20 Jan 31 03:19:50 GumShoe .. have a look through http://papermint-designs.com/community/node/331.. helped me a bit Jan 31 03:19:58 and the followup parts Jan 31 03:21:10 that link is showing bad for me. Jan 31 03:21:23 take out the .. on the end :) Jan 31 03:21:38 ah oops Jan 31 03:21:43 ty shady Jan 31 03:21:46 :) Jan 31 03:22:05 That's the one I've been working from. Jan 31 03:22:51 And a bit of searching on i2cdetect that all seem to point to the same syntax and information. Jan 31 03:23:43 <_Aqua> has anyone connected a 5v relay board from sainsmart to a BBB? I am having some difficulties. Jan 31 03:24:19 be Very careful interfacing to the beagle .. as its quite easy to damage it Jan 31 03:24:38 5V may be too much for the io pins Jan 31 03:25:37 <_Aqua> I'm isolating it as the relay module supports that. putting 5v to the relay coils and only 3.3v to the pins connected to gpio's Jan 31 03:26:14 sounds good Jan 31 03:26:22 latching relays? Jan 31 03:27:33 <_Aqua> http://www.sainsmart.com/8-channel-dc-5v-relay-module-for-arduino-pic-arm-dsp-avr-msp430-ttl-logic.html Jan 31 03:27:39 <_Aqua> that's the board I am working with. Jan 31 03:29:24 * N2TOH gaaah! why no latching relays? Jan 31 03:29:43 why latching? Jan 31 03:29:50 latch in s/w :P~ Jan 31 03:30:16 they only draw power for the coils when setting or resetting them Jan 31 03:30:37 thats normally handled by board electronics Jan 31 03:31:17 unlike typical relays that draw power to keep the coil energized Jan 31 03:31:26 FWIW this is my: "Thermo Numitron Clock" http://rodaw.me/M7njoH Jan 31 03:32:11 Time displayed on Numitron tubes, temperature read on my phone from XML from nodejs Jan 31 03:33:20 <_Aqua> at any rate; the bbb seems to be able to trigger the coil, it clicks, but that's it, it's not switching the port on. Jan 31 03:34:23 I remember one time working on a relay board where I heard the relays click, but they weren't actually engaging. I just need a few more milivolts. Jan 31 03:35:51 veremit were you using the Angstrom distribution when you were working with i2c? Jan 31 03:36:02 no .. debian Jan 31 03:36:17 Hmmm Jan 31 03:58:33 how do i print something using uart on minicom Jan 31 03:58:34 > Jan 31 03:59:41 echo "blah" >/dev/ttyZZ Jan 31 04:01:35 how about using python ? Jan 31 04:01:45 pyserial? Jan 31 04:02:01 the example given in adafruit says serial.write ("hello world!") Jan 31 04:02:11 where does that get printed ? Jan 31 04:02:44 hmm... whhats in the top of that example/program then? Jan 31 04:02:57 ill give u the prog Jan 31 04:03:52 import Adafruit_BBIO.UART as UART import serial UART.setup("UART1") ser = serial.Serial(port = "/dev/tty1",baudrate=9600) ser.close() ser.open() if ser.isOpen(): print "Serial is open!" ser.write("Hello World!") ser.close() Jan 31 04:04:00 sorry ill post it properly Jan 31 04:04:18 import Adafruit_BBIO.UART as UART Jan 31 04:04:21 pastebin? Jan 31 04:04:32 how do i paste a code ? Jan 31 04:04:37 UART1 on BBB is the UART1 pins Jan 31 04:05:07 UART2/3/4 etc Jan 31 04:06:30 yea i know that .. i connected the hart pin 1 n 2 (shorted it) Jan 31 04:06:39 but i cldnt see the result on the minicom Jan 31 04:07:00 do you know y is it written /dev/tty1 ? Jan 31 04:07:05 did you turn flow control off Jan 31 04:07:36 yea i did Jan 31 04:07:40 I think you need to figure out how minicom works... Jan 31 04:08:07 that it connects to the right port Jan 31 04:09:02 see if i just enable the uart1 n uart2 n then connect the receiver n transmitter of the both Jan 31 04:09:26 n then type something in the minicom i get the result in the 2 mini com windows Jan 31 04:09:55 aniket: tty1 is usually a vt on your display Jan 31 04:10:10 serial consoles are usually ttyS1, ttyS2, etc Jan 31 04:10:16 ttyO? are serial ports on BBB Jan 31 04:10:50 dunno, but veremit is talking uarts and mentioning shorting stuff and then using tty1 :) Jan 31 04:10:53 srry abt thtat Jan 31 04:11:38 @veremit Jan 31 04:11:53 @veremit : did u understand the code that i pasted ? Jan 31 04:12:10 or did u understand @turl ? Jan 31 04:12:25 aniket: did you get to read what I wrote? Jan 31 04:12:36 no i didn't sorry Jan 31 04:12:43 i got disconnected Jan 31 04:13:17 01:09 Turl> aniket: tty1 is usually a vt on your display Jan 31 04:13:17 01:10 Turl> serial consoles are usually ttyS1, ttyS2, etc Jan 31 04:13:52 vt ? Jan 31 04:14:05 virtual terminal Jan 31 04:14:37 so when i write ser = serial.Serial(port = "/dev/tty1",baudrate=9600) Jan 31 04:14:37 the thing that looks like a terminal that you can use when you're not using X.org Jan 31 04:15:29 aniket_: I don't know your hardware and just picked it up out of context Jan 31 04:15:47 but tty1 is very likely wrong if you're intending to use an actual, physical, uart Jan 31 04:16:01 oh Jan 31 04:16:10 how do i find out the actual hart > Jan 31 04:16:14 uart^ ? Jan 31 04:16:52 what's your hardware? Jan 31 04:17:15 beaglebone balck Jan 31 04:17:22 black^ Jan 31 04:18:40 aniket_: google tells me you need to do some magic dts overlay dance to mux the uart pins correctly, have you done that? Jan 31 04:19:13 its easier to 'fake' the UART cape... :) Jan 31 04:19:24 magic dts Jan 31 04:19:29 i have no idea what that is Jan 31 04:19:43 well, I'm not really familiar with the BB hardware, I can just provide general advise Jan 31 04:20:12 http://hipstercircuits.com/enable-serialuarttty-on-beaglebone-black/ I found this Jan 31 04:20:20 maybe veremit can get you an easier solution though :) Jan 31 04:20:52 once that's done, you'll need to use /dev/ttyOn, with some number instead of n Jan 31 04:21:13 good night guys Jan 31 04:21:37 alryt thanx Jan 31 05:22:45 vermit around? I imaged a debian relase. Had the saye i2c troubles. Jan 31 05:23:14 Can you point me to the part, the chip, you used? Jan 31 05:23:34 for an i2c EEPROM for a cape? Jan 31 05:24:59 24lc something Jan 31 05:25:13 same one they use on the board Jan 31 05:26:52 I gotta sleep .. just gone 5:30am :( Jan 31 05:26:53 is it true that there is no support for the WiFi cape (TiWi-BLE) in 3.8 Kernel.. Jan 31 05:27:00 niters! Jan 31 05:27:08 CAT24C256W Jan 31 05:27:34 24x -series EEPROM .. lots about .. we used a microchip one Jan 31 05:27:39 256bytes Jan 31 05:28:04 I'm in need of a little wlan 802.11 help here... I'm trying to enable realtek wifi adapter on my beaglebone, and I've almost got it working, but I can't get wlan0 to connecting to my home network. If I put the adapter in ad-hoc mode, then run `iwconfig wlan0 dummynet`, then I can see "dummynet" listed under wifi devices on my macbook. So I know it's working. It's almost like I've specified incorrect ssid and passphrase in /var/ Jan 31 05:28:05 lib/connman/wifi.config, but I've triple checked that. Jan 31 05:28:08 ok I'm out .. g'niters Jan 31 05:28:21 gNight Jan 31 05:30:19 iandow_: Im not sure abt mac.. but what i tried in my ubuntu is edit /etc/network/interface with ur wifi network userid and password, tehn do "sudo ifconfig wlan0 up" and then "sudo ifup wlan0" Jan 31 05:33:30 you mean /etc/network/interfaces (plural), I think. Jan 31 05:33:41 I'll try that Jan 31 05:34:28 yeah interfaces Jan 31 05:36:21 jesus. that worked. Jan 31 05:36:38 brilliant! Thank's man. Jan 31 06:09:04 Does anyone know how to make "ifup wlan0" happen automatically upon bootup? Jan 31 06:13:34 just add auto to interfaces file Jan 31 06:14:44 something like this Jan 31 06:14:44 http://support.arpnetworks.com/kb/vps/example-etcnetworkinterfaces-for-debian-and-ubuntu Jan 31 06:20:38 thanks Jan 31 09:20:42 Can anyone help me with TiWi-BLE and BBW with Angstrom Jan 31 09:33:04 whats tiwi-ble? Jan 31 09:34:06 its beaglebone cape Jan 31 09:34:54 hm okay Jan 31 09:35:00 sorry cannt help with that Jan 31 09:35:41 oh this chat wont provide any help on cape Jan 31 09:36:08 hm a lot of people are heading to fosdem Jan 31 09:36:13 so better ask next week Jan 31 09:37:02 Angstrom supports bluez package ? Jan 31 09:38:09 yes Jan 31 09:38:20 opkg update Jan 31 09:38:28 opkg list | grep bluez Jan 31 09:39:08 if anyone heading from sthlm, i will hop along. Jan 31 09:39:25 :p Jan 31 09:40:22 thanku Jan 31 10:22:30 heya, I got a question, how many amps can you set on the mini usb, couldn't find a safe maximum. Jan 31 10:23:04 Brought a beaglebone black with a 4inch touchscreen cape, and in the manual i find that it uses in total around the 2A Jan 31 11:31:55 hello. regarding continuous sampling the ADC on the BBB, i found these two resources: http://beagleboard-gsoc13.blogspot.de/2013/07/sampling-analogue-signals-using-adc-on.html and http://spoonox.com/?p=25 Jan 31 11:32:57 unfortunatly, they both do echo 1 > /sys/bus/iio/devices/iio_sysfs_trigger/add_trigger which in my case does not exist, even though the BB-ADC dto is loaded. what am i doing wrong here? Jan 31 12:46:29 Oh man i loveeeeeeeeeeeeeeee Beagle man, so good on it for all Linux fun Jan 31 12:47:36 Hi all, I want to ask about adding static routes to beaglebone black. I can add it in startup scripts by "route add ...", but when network is disconnected, added routes gone away. How can I add static routes with connman? Jan 31 12:48:02 I use default Angstrom distribution on my BBB. Jan 31 13:13:11 hello can any one explain how to use beagle bone as plc Jan 31 13:23:30 plc? Jan 31 13:28:50 programmable logic controller Jan 31 13:35:12 ssl running Angstrom? Jan 31 13:39:06 spoonx yes Jan 31 13:39:15 *spoonox Jan 31 15:04:33 Newbie question: is the BeagleBone Black better than the older white one (just called "BeagleBone")? Jan 31 15:05:04 beagleboard.org has the answers Jan 31 15:43:00 I want two sound cards(TLV320AIC3106) for my BBB.One sound card is working fine with the refernce design and the DTS file of audio cape (i2c address 0x1b).One more TLV320 IC(I2c address 0x18) I wanted to activate as sound card 2.What changes should I make ? Jan 31 15:43:07 and where ? Jan 31 15:47:43 Hallo Beaglebone freunde , ist ein deutschsprachiger freak unter euch ? Jan 31 17:58:55 need to brainstorm the best way to do this guys: have beagle bone device that connects over wifi. i built a script that will send the available wireless network to a public server/app where you select wireless network and the password, bone then takes that info and connects to wireless network, all while wired. my issue, is i want to only use wired when there is no wireless, and wireless when there is no wired. Jan 31 18:27:30 hello Jan 31 18:29:42 Hey. Jan 31 18:30:11 What's the difference between the processor on the A6B vs earlier revisions? Jan 31 18:31:20 Only EtherCat? Jan 31 18:33:38 not sure.. think it tells u at beagleboard.org Jan 31 18:35:14 oh noes they going to slower processor? Jan 31 18:35:18 This version moves to the AM3358BZCZ100 processor as we are no longer able to get the limited production version of the AM3359AZCZ100. Jan 31 18:35:22 Same clock. Jan 31 18:35:51 will check differences at ti.. brb Jan 31 18:36:14 Not easy to tell. Jan 31 18:36:27 At least the site itself. Maybe the datasheets. Jan 31 18:39:38 hrm.. yeah only thing i see different is 3358 has adjustable clocks Jan 31 18:39:43 Is there a way to tail -f dmesg on Angstrom? Jan 31 18:40:13 i just use dmesg | less Jan 31 18:40:31 I want to see if roll in real time, though. Jan 31 18:40:37 it roll Jan 31 18:42:42 the datasheet clearly describes all family variants Jan 31 18:42:49 this is common with silicon Jan 31 18:43:24 iandow_, try 'cat /proc/kmsg' Jan 31 18:45:41 k4jcw_, thanks! Jan 31 18:48:03 mpd yeah all characteristics are same, difference must be in way cpu clock can be manipulated... 3359 fixed 3358 variable Jan 31 18:49:44 dogrocket: Don't think so. Jan 31 18:49:46 iandow_, note that doing it that way is not ideal, but it will work. See this page: http://superuser.com/questions/289239/is-it-possible-to-tail-f-the-output-of-dmesg Jan 31 18:50:46 dogrocket, http://e2e.ti.com/support/arm/sitara_arm/f/791/t/221700.aspx Jan 31 18:50:47 mdp: Not so clearly. :) At least the datasheet not. It's from 2013/4, and there's no mention of differences. It doesn't even include the 1GHz (*100) version listed. Jan 31 18:51:33 well, they don't update them on a daily basis Jan 31 18:51:41 contact your rep Jan 31 18:52:02 Hmm... the tech ref seems to be the right doc. Jan 31 18:52:09 Sorry, that should have been directed to ZiNC Jan 31 18:53:31 Thanks. Checking the tech ref. Jan 31 18:55:40 At least the table at the beginning suggests it's just EtherCAT. Jan 31 18:55:59 Also, the 3358 used is 3358B, which is a newer revision than the 3359A. Jan 31 18:56:46 mdp: Was just curious. There no rep I can contact. :) Jan 31 18:56:48 +is Jan 31 18:58:30 so ethercat is differnce, what is that? ability to boot from enet? Jan 31 18:58:39 No. Jan 31 18:58:49 http://en.wikipedia.org/wiki/Ethercat Jan 31 19:00:00 I'm adding an EEPROM to a cape I've built, tested and is working. Jan 31 19:00:29 In reviewing the nullcape post and the schematic in the BBB ref. I'm a bit perplexed. Jan 31 19:01:18 "Passing through"? That almost makes it sound like a token ring network. Jan 31 19:01:24 I've tied a0, a1 and a2 low via 4.7k resistor and I can read the EEPROM. In fact I wrote some data in it on an Arduino, and am reading that data on the BBB. Jan 31 19:01:26 ZiNC, very important to have a tribal knowledge contact when dealing with TI. :) Jan 31 19:01:41 oh ethercat is for automation type stuff. no big loss dont think Jan 31 19:02:03 mdp: I don't think I got one with my BBB. :) Jan 31 19:02:49 ZiNC, didn't stuff the box properly, I guess ;) Jan 31 19:02:50 cat /proc/sys/tirep Jan 31 19:03:00 The schematic in the BBB ref shows to tie a2 high and use a switch to address select to ground a0 and a1. Jan 31 19:03:20 GumShoe, what's the actual question? Jan 31 19:03:54 mdp: Dunno. I'll just ask the store to send it to me. Jan 31 19:04:04 good plan Jan 31 19:04:23 Why am I having the opposite behavior in my circuit as opposed to the refrence cirucuit in the BBB documentation? Jan 31 19:04:50 What's the 'opposite behavior'? Jan 31 19:05:23 I expected to tie a0,a1 and a2 high and have the EEPROM address at 0x50 Jan 31 19:05:46 What's the EEPROM part number? Jan 31 19:05:47 It answers at 0x50 if I tie them low. Jan 31 19:06:21 well... use it that way.. adapt man, just kidding Jan 31 19:06:45 Fairchild FM24C256FLEM8 256Kb fast serial EEPROMs 24C256 Jan 31 19:06:51 IIRC, those pins often have internal pull-ups. It's almost always a bad idea to use a pull-down resistor. You use pull-ups when tying pins to Vcc, but tie them straight to ground when you want them low. Jan 31 19:10:39 Interesting in the BBB SRM http://beagleboard.org/static/beaglebone/latest/Docs/Hardware/BONE_SRM.pdf bfig. 24 Jan 31 19:11:50 it shows a schematic that acts as my circuit is. Jan 31 19:12:14 Interesting, how? They're tied straight to ground. Jan 31 19:12:41 I was going by a schematic that is apparently for an earlier rev of the board I found in this NullCape article http://papermint-designs.com/community/node/331 Jan 31 19:12:43 No. The address of the EEPROM is 0x50 with A2, A1, and A0 low. Jan 31 19:12:52 Yup. Jan 31 19:12:59 If you tied A2 high, for instance, it would be at 0x58 Jan 31 19:13:28 Sry, 0x54. Jan 31 19:14:09 so to get it into the cape addressing I have 4 combinations tying a0 and a1 high. Jan 31 19:14:19 leaving a2 low Jan 31 19:14:22 When people talk I2C, some people treat it as 7-bit addressing, ignoring the R/-W bit (basically, shifting it right one bit). The rest of the world uses the full 8-bit address. I, personally, consider the EEPROM to be at 0xa0. Jan 31 19:15:06 Correct. Jan 31 19:16:19 Thanks for listening. I find I often answer my own question _after_ posting the question... I had _assumed_ the schematic in the article was correct. Yup I know about assumptions. Jan 31 19:17:24 It makes an ass out of u and umption. Or so sayeth Samuel L. Jackson :) Jan 31 19:18:07 My favorite lorum ipsum http://slipsum.com/ Jan 31 19:18:45 Oh, I *like* that. Jan 31 19:19:24 GumShoe AKA @jhalbrecht aka KF7CRU Jan 31 19:20:49 Nice to meet you. Jan 31 19:21:00 Check out my cape: "Thermo Numitron Clock" http://rodaw.me/M7njoH Jan 31 19:21:50 The tubes I wrote in c++ and I serve up some XML that is read from the Phone with nodejs. Jan 31 19:22:02 Verra nice! I've not played with Numitrons. Nixies, yes. Jan 31 19:22:22 It's also my first PCB from OSHPark Jan 31 19:22:53 "fist", if I believe the text under the picture. Jan 31 19:23:28 Ack! as in NAC Jan 31 19:23:54 fixed. Jan 31 19:26:00 I'm currently in the process of building a WiFi-based printer using a BBB. Sketching out what I want in the cape before I lay it out. I shoot competitively (which is not necessarily to say "well"). In the last couple years, we moved from scoring on paper to scoring electronically. One of the things we lack is a low-cost battery-powered WiFi-based printer for printing competitor results. Jan 31 19:26:28 Hi,I am working with a buddy who is the main programmer. I'm a hardware designer. I'm on the east coast, he is on the west. I'm trying to find how the easiest and most efficient way to load code changes as he makes them so I can test them out (we are making a camera engine). We have VNC installed so he can remote into my hardware. Seems the best way, so I don't have to compile anything, is for him to share the SD card image. con' Jan 31 19:26:59 I've got the software 95% done, and now working on the cape that's basically a power supply/battery charger using a 4S LiFePo, and also includes connectors for the printer (32-column serial thermal printer), a few switches and LEDs. Jan 31 19:27:17 Can and how do you make this image? Jan 31 19:28:36 running beagleboard xm with angstrom Jan 31 19:29:37 second question - how do you get "Alignment trap in kernel: swapper (0) PC=...." to stop streaming over the serial port? Jan 31 19:30:58 GumShoe: Did you use someone else for PCBs in the past? Jan 31 19:31:25 k4jcw I'm curious are there many or any mobile apps for scoring these shootOuts? Jan 31 19:31:51 ZiNC I've just made a few single sided at home using toner transfer method. Jan 31 19:32:16 There's a couple. The original electronic scoring system was Palm-based, and good for it's day, but never really caught on due to cost and screen size. Jan 31 19:32:25 JLee: Why a whole image rather than just giving him direct access to the device? Jan 31 19:32:32 I was very pleased with OSHPark, and hear nothing but good from other folks too. I built the schematic and board with Diptrace. Jan 31 19:32:45 Actually, there were two for the Palm. The one that's gained the most traction in the US is PractiScore (www.practiscore.com). Jan 31 19:33:14 GumShoe: Why OshPark? Jan 31 19:33:16 It's both an Android and iOS platform app, and works pretty well, although it still can use a lot of features. There's also a system out of Brazil (I think) called WirTex. Jan 31 19:33:53 WirTex isn't present in the US community, but it also appears to be expensive. Lots of cool features, though. Jan 31 19:34:01 ZinC, I believe that is the plan through VNC, but he asked that I try to find out the best way to get an image across as well. Say I'm on the road or on a demo somewhere and don't have it hooked up to my network and need an update. Thx Jan 31 19:34:41 If he's sharing the SD card image, why not just mail it to you, burn it with a USB/SD adapter, and stick it in the BBB? Jan 31 19:35:49 JLee: So, just read/write the whole thing raw, and that's it, no? Jan 31 19:36:33 k4, that is my thinking too. couple things, I don't know how big the image is (could just use google drive or something if too big for email) and as I understand maybe incorrectly, the file format is not compatible in/with windows. Jan 31 19:36:36 JLee523, https://groups.google.com/forum/#!topic/beagleboard/UJV0XyN-PMc Jan 31 19:37:09 The file format is not, but using any of the common image writer programs will allow you to write to the SD card. You just can't use "copy". Jan 31 19:38:20 k4, thank for pointer to image trap. Jan 31 19:39:24 i did mention an image copy program and it seems unlikely that he hasn't covered that option already, but I'll press the question again. Jan 31 19:40:20 http://sourceforge.net/projects/win32diskimager/files/latest/download Jan 31 19:40:35 You can burn images to the SD card with that. Jan 31 19:41:17 this ok on 64b win7? thx Jan 31 19:41:39 Yeah. Jan 31 19:42:13 very cool. thank you both! Jan 31 19:49:14 hello everyone! I am an electronics engineering student. I have taken a course in 8085 assembly and am currently doing a course in embedded systems. I was wondering if i can contribute to beaglebone? I know c++ and haskell to some extent as well. please help. Jan 31 20:19:11 8085 assembly? Jeez, let's pick a slightly more antiquated processor. Jan 31 20:20:33 4004! 4004! Jan 31 20:20:40 Yay! Jan 31 20:21:03 (I actually have 3 of those, with supporting chips) Jan 31 20:21:05 all these damn bits! Thats where we went wrong! GET OFF MY LAWN! Jan 31 20:22:02 I got mips assembly back in college. Right before they dropped it for another stinking java class. Jan 31 20:22:25 I also have 8008's, 1802's, 8080's, and just about everything north of those. Jan 31 20:23:14 I liked the old processors. You could actually understand the entire processor. Nowadays, no one completely knows how a Pentium works. Jan 31 20:24:50 Hello everybody Jan 31 20:25:05 And now, to reboot after a kernel upgrade. Always with some trepidation... Jan 31 20:26:49 I have Just one question about the avaibility of beagleboard balck, I would buy 2 beagleboard board news version but this product is not availaible in europe Jan 31 20:26:54 i need your support Jan 31 20:27:39 do you know where i can buy this version of beagle board Jan 31 20:29:16 nobody could support me ? Jan 31 20:30:21 Yay. It lives. Jan 31 20:30:44 Nakamura, get in backorder line like everyone else. ;) Jan 31 20:32:30 ok Jan 31 20:33:20 it's difficult to found a distributor wich this beagle board is available Jan 31 20:33:55 Nakamura, "supply < demand" = none-available econ 101.. ;) Jan 31 20:35:00 what do you means ? Jan 31 20:35:57 there's a shortage of answers to problems here too..when will answers be back in stock? Jan 31 20:36:51 Nakamura, economics 101: When demand outstrips supply, availability goes to zero.. Till supply restores stock.. Jan 31 20:37:24 It's a very good product but no stock in europe, I ask you if there are some stock on other country :) Jan 31 20:38:05 mdp: supply chain problem Jan 31 20:38:36 Nakamura, nope... Everyone that is getting stock, is shipping them first to customers in their backorder queue... Jan 31 20:40:18 ok, thanks, but i'm very instressting to use this product. the beagle team should be increase the volume production ;) Jan 31 20:41:19 Where is the EMS supplier ? Jan 31 20:41:45 Nakamura, they have: http://elinux.org/Beagleboard:BeagleBoneBlack#Board_Shipments Jan 31 20:42:17 but remember missing "one" part puts the whole production line down.. Jan 31 20:43:58 Ok so, do you sell your beagle board to me ;) Jan 31 20:45:06 Sure Nakamura, but I expect a lot first, you'll need to take over kernel maintance for beagleboard.org.. ;) Jan 31 20:46:54 it's nice to have somepeople for support Jan 31 20:46:57 ok thanks to you Jan 31 20:47:35 i 'll left you, and we try again to launch an order with another distributor. Jan 31 20:47:55 Nakamura, they'll just put in you backorder queue and you'll get one.. Jan 31 20:48:18 so before to left you, do you know which distributor is the best Jan 31 20:48:25 sorry for my english ;) Jan 31 20:50:35 Best in what way? Jan 31 20:51:07 delivery time Jan 31 20:51:33 the first distributor to have in stock Jan 31 20:52:17 Nakamura, wrong question... "first distributor to finish full-filing their backorders and able to ship out a new order to Nakamura " Jan 31 20:52:32 I'm not sure there's a first. Probably more like, who orders more stock. Jan 31 20:52:55 You can usually get email alerts on stock availability. Jan 31 20:53:15 Some US stores offer decently priced shipping to the EU. Jan 31 20:53:22 (Or close to decent. :)) Jan 31 20:54:29 Thank zinc, but do you have a distributor names Jan 31 20:54:46 The ones in the Beaglebone site. E.g., Adafruit, SparkFun. Jan 31 20:55:20 I don't like some of the others that don't make it easy to see shipping costs and final price. Jan 31 20:56:06 BTW, there's also Seeed Studio in Chinese who do international shipping, Jan 31 20:56:14 though no Beaglebone Black stock in quite a while. Jan 31 20:57:22 ...China. Jan 31 20:57:31 ok great i will inform my team, and i hope i will hall son as possible this wonder board Jan 31 20:59:21 well, clearly I pasted the in stock specialcomp.com link so many times now that they are now out of stock! Jan 31 20:59:27 good job channel residents Jan 31 21:00:12 Overpriced, though. Jan 31 21:00:29 Ok thanks for your support, have a nice day and i wish you an happy new year Jan 31 21:00:50 Good luck. Jan 31 21:00:58 long life to beagle ;) ;) Jan 31 21:01:04 And happy new Chinese year. :) Jan 31 21:14:58 rcn-ee get sgx working first then you can sell your board :O) Jan 31 21:15:27 it works... under qt.. ;) Jan 31 21:16:03 oh, cool im download kde for ubuntu as we speak.. does that mean it should use? Jan 31 21:16:37 qt-embedded.. (non-xorg) display server.. Jan 31 21:16:51 oh... didnt know you could do that.. Jan 31 21:17:16 that sounds good.. probably a lot faster than xorg i bet? Jan 31 21:17:50 it's egl based, it was mostly designed for embedded situations. Jan 31 21:20:02 will have to download that... you have a sgx kernel commit yet? no pressure, actually Im wanting to access the h.264 / aac codec but I'm not even sure they have doco for that .. probably not Jan 31 21:21:02 in my am335-v3.13 tree.. Jan 31 21:21:15 thanks sir, you da man Jan 31 21:34:43 geesh sorry I downloaded kde now.. thing is huge Jan 31 21:42:58 sgx? Jan 31 21:44:13 its the package that will access beagles graphics core... faster graphics opengl Jan 31 21:45:19 but its not working well on latest kernels.. but rcn-ee is working on it Jan 31 21:47:30 kinda like buying a car with air conditioning, but not knowing how to turn it on.. lol Jan 31 21:48:33 id actually say, it's working under the constraints TI's imposed on it.. For the rest of us.. aka unusable.. Jan 31 21:49:50 i just dont understand the secrecy... it may benefit imagine inc. guess they are scared someone is gonna steal thier baby Jan 31 21:51:04 need those guys that reverse engineered nvidia drivers... lol Jan 31 21:51:33 Has anybody here re-compiled their u-boot on the beagleboard-xm itself? Jan 31 21:52:03 I need to change those GPIO mux pins... Jan 31 21:53:33 why on the board? Jan 31 21:53:56 well, i only have to do it once... Jan 31 21:54:10 you mean, why not cross? Jan 31 21:54:17 yeah Jan 31 21:54:39 never done cross Jan 31 21:55:03 for one, I don't know if the signing tool is available for arm Jan 31 21:55:40 dogrocket, interesting. Jan 31 21:55:44 or do you not need the MLO portion Jan 31 21:55:46 ? Jan 31 21:56:41 well, according to ( http://elinux.org/BeagleBoardPinMux ) one can change the expension header mux using u-boot Jan 31 21:57:09 sure Jan 31 21:57:38 I have never done a u-boot build :( Jan 31 21:57:49 Is there anywhere an actual price breakdown of the BBB? Jan 31 21:58:18 ZinC you mean a BOM? Jan 31 21:58:30 or finished prices? Jan 31 21:58:33 Including manufacturing, testing, etc. Jan 31 21:58:57 The BOM XLS doesn't shows only the parts. Jan 31 21:59:22 To bad that the BB-xm mux can not be changed on the fly... Jan 31 21:59:45 ah, you'd probably have to get a quote which varies greatly based on quantity Jan 31 22:00:04 Yeah, but that part you can extrapolate easily enough. Jan 31 22:00:08 I just wonder about the rest. Jan 31 22:01:47 One of the things mentioned on the site was that one of the factors that contributed to the lower price of the BBB was automated testing. It would be interesting to see in detail the whole production process. Jan 31 22:02:15 btw guys, is there an UART on the BB-xm that is enabled by default? so that i do not have to change u-boots and kernels? Jan 31 22:03:03 there is, it's dedicated to the console though Jan 31 22:03:32 yea, but i think that is only the big connector right? Jan 31 22:03:47 the rs232 connector yes Jan 31 22:04:10 but does that mean that the TTL variant on the expension header is also active? Jan 31 22:04:16 the 10 pin connector is on the class not the xM Jan 31 22:05:05 classic Jan 31 23:14:35 Any, re the BBB production price, going by prices for a few thousand pcs, the components themselves cost >60$. Jan 31 23:15:10 This doesn't include the PCB or assembly, nor packaging, etc. Jan 31 23:16:34 The AM335x itself is about 40% of that, but I assume TI provides it at cost in this case. Jan 31 23:18:54 depends on what you are calling 'cost' Jan 31 23:19:10 Seeing that you can buy the end product, if you buy large quantities, for less than $40, and possibly $35, Jan 31 23:19:35 there are probably large savings from TI, but I still wonder how it all works out. Jan 31 23:19:42 What could I call cost? Jan 31 23:27:18 the raw material for semiconductors is cheap Jan 31 23:27:26 sand and lots of it Jan 31 23:27:43 you make them into wafers and get hundreds if not thousands of them Jan 31 23:30:46 Circuitco doesn't manufacture the parts, they just assemble. Jan 31 23:43:06 Does Ubuntu on Beagleboard xm require MLO ? Jan 31 23:52:48 does Ubuntu on a PC require a bootloader? Jan 31 23:56:05 lol. lead time on farnell is now march... Feb 01 00:19:08 so I'm curious, and maybe someone here knows Feb 01 00:19:55 is circuitco just small enough they're having trouble keeping up, or is there some knee in the economies-of-scale curve where if the demand was just a bit higher, it would be possible to make bigger batches of 'bones? Feb 01 00:26:26 Who knows. Feb 01 00:38:31 <_av500_> 54 Feb 01 00:44:54 my Beagle XM won't boot anymore :( Feb 01 00:45:21 <_av500_> it will Feb 01 00:45:28 <_av500_> prepare a good SD card and it will Feb 01 00:45:32 <_av500_> it does in most cases Feb 01 00:45:41 the SD pins appear to be bent :\ Feb 01 00:45:50 why did you do that? Feb 01 00:46:27 good question, i don't even know how. Feb 01 00:46:48 usually it happens by forcing it backwards/sideways.. Feb 01 00:46:55 no, i never did that Feb 01 00:48:02 can i still boot a MLO/u-boot over JTAG? Feb 01 00:48:12 or am i SOL with this thing Feb 01 00:48:50 you could try filling out the rma form, if it's still under warrenty they can replace the microSD connector Feb 01 00:49:37 if not, bend them back, redo the connector yourself, etc.. Feb 01 00:50:24 i also noticed that this board never seemed to have a serial number Feb 01 00:50:56 did you get it from a stranger on a street corner? Feb 01 00:51:12 no, i ordered it from TI Feb 01 00:51:40 i'd contact them first then. Feb 01 00:51:57 just hot air the connector Feb 01 01:11:34 has anyone worked with https://github.com/kelly/node-i2c ? I'm having trouble dulplicating this https://github.com/lamunozh/BeagleBone/tree/master/tsl2561 Feb 01 01:18:08 av500: 54? Feb 01 01:28:16 sad sad sad example..already a tsl2561 iio driver Feb 01 01:28:57 mdp: have you worked with that i2c lib? Feb 01 01:30:57 mdp: do you mean a driver already exists for that chip? Feb 01 01:33:37 do you mean a driver already exists for that chip? Feb 01 01:44:52 is there an Australian dealership Feb 01 01:45:41 has anyone fitted one of htese inside a TV Feb 01 01:45:53 logoff Feb 01 01:45:59 exit Feb 01 01:46:04 quit Feb 01 01:46:23 put a frontslash Feb 01 01:46:27 before Feb 01 01:46:38 cheers Feb 01 01:56:03 doesn't look like there is a driver, has anyone had experience with https://github.com/kelly/node-i2c ? Feb 01 01:57:26 what problem are you havin? Feb 01 01:57:52 all that other drive does is read bytes over i2c Feb 01 01:59:16 poagester, drivers/iio/light/tsl2563.c Feb 01 01:59:41 the python hack is just a waste of time Feb 01 02:10:07 johnwalkr: except for the initialzation, which i can get the correct bytes to write using that i2c js lib Feb 01 02:10:49 mdp: thanks, I'll grab it and read through it, and maybe customize it for my needs if needed. Feb 01 02:13:17 init is just setting gain? Feb 01 02:13:38 oh there’s an on byte too Feb 01 02:13:45 sets gain and turns it on Feb 01 02:14:27 which that works perfect with the exception of not handling a divide by zero condition Feb 01 02:15:12 it's a pretty simple part Feb 01 02:15:19 what i am not sure of is if I am using that ic2 library correctly with the commands, addressing and data. I don't know coffee script Feb 01 02:18:44 mdp: i put a work around in my copy and submitted a bug, but no work has been done for over a year, and as you can see it is not even close to finished. Feb 01 02:22:14 poagester, what are you talking about? not the standard kernel driver I cited. Feb 01 02:27:21 no, the half done python one. Feb 01 02:28:07 oh gosh..if it were me, I'd use a widely tested and complete iio light driver Feb 01 02:28:12 and all the features it provides Feb 01 02:28:15 but that's me Feb 01 02:29:39 up with addresses and commands though Feb 01 02:29:47 im definitely going to read through it and make sure everything match Feb 01 02:29:54 weird Feb 01 02:30:29 hey mdp... do you know if there are docs on the timings for accessing the different types of memory on the PRUs? Feb 01 02:35:04 ds2, not that I know of, just tribal knowledge Feb 01 02:35:24 'k thanks Feb 01 02:35:33 thanks everyone Feb 01 02:35:45 this does mean there is no guarantee one can move data out or into the PRU fast enough :/ Feb 01 02:37:43 ds2, most of what is passed down is from the internal TI PRU folks that do the ethercat and other blobs for the turnkey customers Feb 01 02:38:12 ds2, so yeah, need to do some empirical tests on your own use cases Feb 01 02:50:51 mdp: empirical tests only give "typical" values Feb 01 02:52:28 ds2, yes, I was going to ask if this was for a real product..I guess I should have known with you it is ;) **** ENDING LOGGING AT Sat Feb 01 02:59:58 2014
