**** BEGIN LOGGING AT Wed Dec 04 02:59:58 2013 Dec 04 03:18:39 How fast can the BBB transfer data on a 32GB microSD. Not sure if I should buy the class 10. Dec 04 04:35:37 hi all, does anyone know if there are any efforts to support emulating the beaglebone black in qemu? Dec 04 04:39:52 catmcdog: i don't think there is a stock support for it Dec 04 04:40:05 catmcdog: the real question is why would you want to? Dec 04 04:41:52 thinking about trying some baremetal dev and thought it might make things easier Dec 04 04:42:12 as far as debugging and such Dec 04 06:12:00 are the ttyOx drivers able to go faster than 115200, then kernel I use still has the old ttySx drivers and doesn't seem to be able to handle anything over 115200 reliably Dec 04 06:19:56 I've seen OMAP3 do 1MBaud ages ago Dec 04 06:24:07 that's promising Dec 04 07:11:41 hi Dec 04 07:11:45 anyone here? Dec 04 07:12:05 you hearing my question.. Dec 04 07:21:09 <_av500_> roger, I copy Dec 04 07:33:56 sore land of impatient Dec 04 08:45:28 <`Ishq> Has anyone been able to get cpu-freq/cpupower working under Arch? Dec 04 10:20:06 hi! Dec 04 10:20:39 What is a good identifiers for the omap board? Dec 04 10:21:00 is TAP_ID a proper one or is there something better? Dec 04 10:21:26 I would like to disciminate between the BBXM / and the BBB and BBW Dec 04 12:18:00 I am flipping btw ubuntu and angstrom on the BBB, because I can't get wifi up and running on ubuntu (I need the source to compile drivers, but can't find it)... I am on ubuntu because I need to run nodejs and python, since I have no experience w/ angstrom, does anyone here have nodejs and python running on angstrom? Dec 04 12:34:03 j105rob: afaik the default angström image for bbb comes with node.js installed Dec 04 12:34:13 j105rob: but why would you need node.js anyways? Dec 04 12:47:06 KotH: because I'm lazy :) Dec 04 12:48:46 I have several classes of code I have already written in JS and really don't want to port them Dec 04 12:49:26 Holding on hard to my DRY beliefs Dec 04 13:21:22 j105rob: DRY does not equal to totally-inefficient-and-not-the-right-tool behaviour Dec 04 14:44:16 KotH: :) hence my laziness Dec 04 14:45:13 just trying to throw together a quick prototype for a demo, not doing productin work yet.... and since this development effort is on overhead dollars, just makes sense to do it quick and dirty Dec 04 14:48:52 j j dj1 ohk. then i t makes sense Dec 04 14:59:03 hello Dec 04 15:05:05 i have debian wheezy 7.2 running on a bb black, rev a5c. currently playing with this http://www.4dsystems.com.au/product/22/138/Beagle_Bone_LCD_Capes/4DCAPE_70T/ . the display works well (being based on the LCD7 display), i managed to setup with ts_calibrate, but the touch-pointing device is still not usable, can't click on large parts of the screen. do you guys have any suggestions?? Dec 04 15:10:35 here are some more details http://paste.debian.net/69305/ Dec 04 15:14:02 samael: ask me again in a couple of weeks :) Dec 04 15:15:42 * samael takes note ;) Dec 04 15:16:56 meanwhile, is there a 7" touch display for the bbb correctly working on debian? i'd need it to show in a demo Dec 04 15:30:37 samael: it's most probably a software problem, and also most likely not directly related to the display Dec 04 15:30:51 samael: but as i have not worked with touchscreens myself yet, i cannot tell for sure Dec 04 15:53:29 KotH: i suspect this too. i'm going to play with angstrom to have a look Dec 04 19:00:40 Hi all Dec 04 19:01:03 where can I find latest beaglebone black image Dec 04 19:27:38 viraniac, you could get it at http://beagleboard.org/Support/Software%20Support Dec 04 19:35:42 I tried to update my BBB's packages, while booted to eMMC, ran out of room, and apparently trashed my OS, even though my heartbeat LEDs are still working. I get no client USB functionality on any computer. Nothing in device manager or lsusb. I've loaded a SD card with the BBB-eMMC image and tried booting holding the user button, but nothing seems to have changed. Dec 04 19:36:23 Do I have any recourse without the debugging cable? Dec 04 19:36:44 probably not Dec 04 19:40:08 SoCo_cpp_: you do want to have a serial cable anyways. it helps debugging various stuff a lot easier Dec 04 19:40:36 SoCo_cpp_: and you can get those for 5 usd on ebay or somewhere between 10 and 30usd from online stores Dec 04 19:41:04 I got a debugging cable from a coworker, apparently we had some extra. This should shed some light on the issue. Dec 04 19:41:45 (this cable might disappear today and wind up at my house) Dec 04 19:41:50 hehe Dec 04 20:01:37 Hi, what's the best way to connect a thermistor to analog input of bb black? Dec 04 20:01:53 I've screwed up my systemd ( systemd[1]: Failed to start default target: Unit sysinit.target is masked. ) and so my BBB is hanging on boot. On traditional linux distros I would use single user mode to boot up and fix whatever I screwed up. Not sure how to do that with U-Boot and systemd, and my google-fu is failing me. Anyone know of a way to change the boot level target from u-boot? Dec 04 20:02:28 m8: you can look at the schematic for the bacon cape. it has a 10k ohm slider pot that works in a similar fashion Dec 04 20:02:42 prpplague, only one? Dec 04 20:03:00 m8: i did not understand your question Dec 04 20:03:16 read value from a thermistor on a beaglebone analog port Dec 04 20:03:29 of a from :O Dec 04 20:04:24 m8: i am sorry i did not understand your statement Dec 04 20:04:38 prpplague, do you know thermistor? Dec 04 20:05:20 m8: the bacon cape has an example of how to use the analog to digital converters. this example uses an variable resistor which works in a similar manner as a thermistor Dec 04 20:05:26 m8: yes i do Dec 04 20:06:11 prpplague, it's not equal because the resistance is equilibrated in a potentiometer Dec 04 20:07:07 m8: yes not exactly the same, but similar Dec 04 20:07:14 m8: just use one side Dec 04 20:07:32 with one side i can't have voltage divider Dec 04 20:08:32 * prpplague shakes his head and goes back to work Dec 04 20:08:49 carpman: make a note to get a wiki page up with an example for thermistor Dec 04 20:09:14 m8: what is the part number of the thermistor you plan to use? Dec 04 20:12:23 pt1000 Dec 04 20:17:43 m8: got a link to a datasheet or product page? Dec 04 20:20:14 <_av500_> pt1000 is pretty standard Dec 04 20:22:54 _av500_: yea i came up with a pretty large list, just wasn't sure which one Dec 04 20:23:11 _av500_, yes Dec 04 20:23:57 <_av500_> they should be all the same Dec 04 20:24:02 <_av500_> if they are pt1000 Dec 04 20:26:49 * prpplague orders a few Dec 04 20:27:39 <_av500_> I need a few pt100 or 1000 on my BBB to monitor my heating Dec 04 20:47:31 hey I was wondering if anyone knows how to disable/enable the USB host port on the BBB. I'd like to "unplug" the device and "plug" it back in without physically doing it. Dec 04 20:50:28 is it the processor that beagleboard black have http://se.mouser.com/ProductDetail/Texas-Instruments/AM3358ZCZD72/?qs=sGAEpiMZZMtMbLhITnKwtwIIYllslySK Dec 04 20:51:09 kjsa: the current revision of the beaglebone black uses the AM3359 Dec 04 20:51:15 I mean, there's like tens of different places where every little thing on the bbb is described Dec 04 20:52:05 palesius_: there is a generic sysfs entry for doing that on a usb hub Dec 04 20:52:19 kjsa: http://se.mouser.com/ProductDetail/Texas-Instruments/AM3359BZCZA80/?qs=sGAEpiMZZMtF2lsQzIlof6F8BuKgpgv0 Dec 04 20:54:30 prpplague, do you know how many of beagleboard black is produced per year, the processor cost almost the same what the board cost :) and has many components + labor + profit margin + other costs Dec 04 20:54:38 Dear All, I am an absolute beginner to these kinds of boards. i have been doing Low Level Microcontroller programming like over PIC by microchip. Dec 04 20:54:52 but now i want my hand on it. anyone with any advise or suggestions. Dec 04 20:54:54 ? Dec 04 20:55:32 kjsa: just the generic public beaglebone black shipments are listed here - http://www.elinux.org/BeagleBoneBlack#Board_Shipments Dec 04 20:57:20 do you know what omap processor is the cheapest that can run linux? Dec 04 20:57:36 is it the one what beagleboard black has? Dec 04 20:57:55 kjsa: the am3359 is pretty darn cheap Dec 04 20:58:33 (although it is technically not omap) Dec 04 20:58:53 when I saw the end price of the black, I was expecting to see the CPU price like 5 euro or something :) Dec 04 21:04:15 prpplague, I don,t have knowledge or skill to be able to create such embedded board but I wonder if one gets openhardware design and say it uses omap or sitara processor, does the processor need to be programmed in order to run linux Dec 04 21:04:35 or is it the default cpu what it is used on the board Dec 04 21:05:15 kjsa: the processor doesn't need to be "programmed", but it does need to have something to boot Dec 04 21:05:52 kjsa: the processor costs for the beaglebone black are figured in with the purchase of 250,000 units Dec 04 21:05:55 hi Dec 04 21:06:05 kjsa: significant discount for bulk purchase Dec 04 21:06:15 sure it should be Dec 04 21:06:17 guys what's the default password for the angstrong Dec 04 21:06:20 distribt Dec 04 21:06:35 default root password Dec 04 21:06:38 TI does not own any beagle boards, right? Dec 04 21:08:02 I could not understand from the webpage if it is a company produce the beagle boards Dec 04 21:08:10 kjsa: http://www.beagleboard.org/about Dec 04 21:08:34 kjsa: beagleboard.org is a non-profit organization Dec 04 21:08:41 kjsa: the design is open Dec 04 21:08:51 kjsa: it is manufactured by circuitco Dec 04 21:09:49 prpplague, thank you Dec 04 21:32:56 I can't get this BBB to boot from the SD card for anything. I hold down the user button, and it still boots from the MMC. I am trying to run the MMC flasher ISO off the SD card. I am watching the debug cable output. What can I try?

Dec 04 21:51:20 SoCo_cpp, double check the partitons and if first is bootable Dec 04 21:58:37 looks like I have a bootable FAT32 partition and a linux partition on both mmcblk0 and 1 Dec 04 22:03:29 I've got a terminal and I'm just trying to restore the stock image, so I think I can pull this off... Dec 04 22:18:49 Hello all, Dec 04 22:19:05 Has anyone connected a mcp3008 ADC to the BBB using api? Dec 04 22:19:08 spi* Dec 04 22:19:42 Specifically using the Adafruit.SPI python package Dec 04 22:20:40 I can't seem to find any literature out there on it, I can for the raspPik, but not for the BBB Dec 04 22:21:58 Ill just give you guys some time to think doooo but dop baaa Dec 04 22:22:43 no worries, take allll the time yall need Dec 04 22:25:03 Hi everyone, I have an issue with SD card where I can see the partition on my PC when the BBB is connected, but I cannot connect to it via browser or find it using port scanner. I flashed a brand new image to it. Dec 04 22:25:51 It worked initially until I pressed the reset button, I re-flashed it since without any success Dec 04 22:28:04 Without SD card it works just fine, I'm making sure to power it with a 5V 1A power supply and the USB cable together Dec 04 22:34:05 [kernel] clacey09 opened pull request #79: Get Ready for AIC3104 Audio Cape and Clean Audio Patches (3.8...3.8) http://git.io/3WL4jA Dec 04 22:35:05 [kernel] RobertCNelson pushed 2 new commits to 3.8: http://git.io/iOZCEQ Dec 04 22:35:05 kernel/3.8 c5acba3 Cody Lacey: Get Ready for AIC3104 Audio Cape and Clean Audio Patches...

Dec 04 22:49:07 nice github bot Dec 04 22:49:08 :D Dec 04 22:49:13 been away for a few days Dec 04 22:56:58 Hello, I was forced to log out, but I'm still looking for help with a question I asked previously, where I am having an issue trying to boot off SD card with BBB, I can see the partition in Windows just like with the eMMC, but cannot connect via SSH or web browser Dec 04 22:57:32 *Log out of IRC, with a different name Dec 04 23:03:19 wtf, now I can't see the original NAND partition nor connect to it, nor the serial port. Could this be the win64 drivers? Dec 04 23:25:42 Kennetho: it could be, you can always check the serial console if you have a cable Dec 04 23:58:58 thews_: the user lights stopped working, only the power light comes on and off, I'm downloading the flashing image, but this will be another hour. It stopped working on it's own, I had no intervention, it stopped showing the partition with or without the SD card. Does this mean the processor stopped working? Dec 05 00:00:00 do you have a serial console (usb to 3.3 or 5V ttl) cable? Dec 05 00:24:26 Is this the 5 volt FTDI cable that I can make from a USB cable and 6 pin header? Dec 05 00:24:54 And an FTDI chip, yes. Dec 05 00:24:59 Updaite: I downloaded the Flash partition, tried to boot with 5 volt PSU and holding down the boot button, but no user lights come on Dec 05 00:25:18 I don't have that cable Dec 05 00:25:44 Does this mean the processor is dead? Is there any other way to check? Dec 05 00:26:21 I doubt very much the processor is dead. Dec 05 00:27:57 are the user lights supposed to come on when only the power cable, not the USB cable, is plugged in Dec 05 00:33:26 Yup. Dec 05 00:33:43 That is part of the boot process, no matter where the bone is powered from/. Dec 05 00:41:55 I found a blog that corresponds exactly to what happened with my BBB Dec 05 00:41:59 http://www.reuk.co.uk/wordpress/bricking-a-beaglebone-black/ Dec 05 00:42:20 Seems like the device has some hardware issues Dec 05 00:42:57 Could be. Dec 05 00:51:00 if you don't have a serial debug cable there's no way to know Dec 05 00:51:08 if you don't have one, get one. Dec 05 00:52:52 it's that simple. you can bang your head on a wall for days or buy a cheap console cable for a few euros/dollars Dec 05 00:54:43 and that blog.. he would have been fine with a console cable as well ;) Dec 05 00:55:37 although I can read between the lines that the writer doesn't know enough about linux to comfortably muck about with embedded linux.. but I guess that's where we're at today with the RPi bringing embedded linux to the masses ;) Dec 05 00:56:12 ANd the beagle products. ;-P Dec 05 00:56:56 I blame arduino also Dec 05 00:57:13 Because of how many people are running embedded linux poorly on them? Dec 05 00:57:17 yeah, me too. ;-P Dec 05 00:57:43 naah not really, those guys do great work but still.. people move forward faster than their skills and suddenly they're in the deep end of the pool and they can't swim Dec 05 00:58:21 Welcome to literally everything ever. Dec 05 00:58:34 people come on the channel and ask "how can I make own linux from scratch?! omg help pls" Dec 05 00:58:50 and they don't know shit about linux or even the difference between kernel and userland Dec 05 00:59:28 ok, probably half of those are from the indian subcontinent and they're asking us to do their homework Dec 05 00:59:40 A for effort.. Dec 05 01:01:53 it's great that there's a complete stack of stuff all the way up to a node.js gui or something.. but that stack is high and fragile, when it breaks you really fall hard if you just skipped all the basics for the platforms Dec 05 01:03:06 I still find it amazing that for most people using RPis the only way to fix ANYTHING on them is to reflash their SD card with a stock image and start over :D Dec 05 01:03:29 } /* end of rant */ Dec 05 01:04:04 To e fair, with the state of a lot of the software out there for them these days, that frequently *is* the fastest solution. Dec 05 01:04:09 Just saying. ;-P Dec 05 01:05:25 but it is an amazing stack of stuff compared to where you were 10 years ago with embedded linux Dec 05 01:05:41 everything drops into your lap out of the box Dec 05 01:06:59 Well, 10 years ago with embedded linux I was thinking it might be neat if I could have Wikipedia on my iPod, so my 7th-grade homework was easier to do on the bus. Dec 05 01:07:03 But I see your point. Dec 05 01:08:01 D Dec 05 01:08:07 oops.. I feel old Dec 05 01:08:13 Heh. Dec 05 01:08:32 No worries, the rental car agencies will finally stop harassing me next month. Dec 05 01:11:02 when I was in 7th grade, CERN was starting to migrate to TCP/IP Dec 05 01:11:17 so it was a bit early for wikipedia access.. Dec 05 01:12:39 Heh. Dec 05 01:12:45 actually Finland joined the Internet one year later. Dec 05 01:13:12 university network was connected in '88 Dec 05 01:14:02 1988 was a good year. Dec 05 01:20:25 Vaizki_: I see communication on the UART lines with a Logic Analyzer Dec 05 01:20:59 Just decode that. Should be close enough. Dec 05 01:21:16 Use a tac switch on the TX line, and hit it really fast to talk back to the bone. Dec 05 01:22:13 Kennetho: you have a LA but no usb serial? :) Dec 05 02:43:54 hi every one I have a questioin. Does the Beaglebone white come shiped with an os. Ijust got one at a confrence the other day and all I can do is get a power light. Dec 05 02:45:13 Yes, it ships with an OS on the microSD. What conference and what revision? Dec 05 02:47:28 It was more of a demo at my local college. Rev a2 072 Dec 05 02:56:21 any thoughts on what I should check next jkridner? Dec 05 02:56:34 that was me that gave the demo. ;) Dec 05 02:56:42 Hehe Dec 05 02:56:49 The A2 microSD cards are blank. Dec 05 02:58:18 Hazeshadow: program a microSD card using info at http://elinux.org/Beagleboard:BeagleBone Dec 05 02:59:09 I think it is 2GB. Dec 05 02:59:20 so, you might need a bigger card. **** ENDING LOGGING AT Thu Dec 05 02:59:58 2013
