**** BEGIN LOGGING AT Mon Mar 31 03:00:00 2014 Mar 31 03:00:42 Windows 8. Mar 31 03:01:32 check the device list to see if the driver is loaded, Mar 31 03:04:49 Can't find the drivers on win8. Part of the reason I wanted to learn linux. Mar 31 03:06:01 thomson_: "It worked before" from the same win box? Mar 31 03:08:17 Yes, same laptop. Mar 31 03:09:08 the debug tool nr1 is a UART cable for the BBB. there you could see the serial console. connect one Mar 31 03:11:47 the console cable... good thinking... ( I knew I should have ordered one with my BBB from Adafruit... Mar 31 03:11:52 ) Mar 31 03:13:45 jbdatko: got things going finally Mar 31 03:14:35 Unfortunately, when I say I'm new, I mean completely. Most of what is said is Greek, at this point. Mar 31 03:15:03 the beagle bone black spits out a bunch of data out it's serial port.... Mar 31 03:15:07 while it boots up. Mar 31 03:15:48 so if you have this serial console cable connected.... you have a behind the scenes look at what's going on, and it may give you some insite Mar 31 03:17:00 The laptops "sees" it, i can open the START item with Chrome. It then goes into a setup page. It doesn't seem to recognize that the BBB is plugged in and the drivers are installed. Mar 31 03:17:26 I have the BBB open on another monitor, is there anything I can do from there? Mar 31 03:17:41 do you get a login prompt? Mar 31 03:17:44 thomson_: type ifconfig Mar 31 03:18:00 (beat me to it... and I would have messed up the syntax....) :) Mar 31 03:19:02 there you see the IP Addresses Mar 31 03:19:22 forgive my wet-behind-the-ears-ness, but how do I open the command prompt? Mar 31 03:21:44 It skips the login prompt, automatic login. Goes into a GUI. Mar 31 03:21:53 when you look at the BBB screen what do you see? Mar 31 03:21:57 oh Mar 31 03:22:10 then you want "terminal" Mar 31 03:22:21 ah, (my bbb has not arrived yet...) :) Mar 31 03:22:54 lxterminal on debian, depends on which flavour of distro you are using i think Mar 31 03:23:20 oh, well the softwares the same between boards i think..... im quite new to all this as well Mar 31 03:23:20 Angstrom. I cannot find "terminal" Mar 31 03:23:57 Found it. Mar 31 03:24:53 should bring up a command prompt where you can then enter "ifconfig" and hit enter... and it will give you a heap of info Mar 31 03:26:01 It did. the inet addr:192.168.7.2 is what I was trying to connect the laptop to. Mar 31 03:26:59 They are apparently talking, as there has been 115k recieved and 6k sent. Mar 31 03:29:11 Yet chrome cannot connect to that address. Mar 31 03:33:00 gether issue ive yet to nail down myself Mar 31 03:34:05 had this issue when i rolled my own debian, could not connect from the laptop until i pinged the lappy from the BBB ( via ssh ) then i could connect to it for a little while. then it would go round, and around like initially Mar 31 03:34:30 its definately related to gether, butcause over ethernet it works fine Mar 31 03:35:10 So how do I ping via ssh. Mar 31 03:35:12 ? Mar 31 03:35:32 you connect to the BBB via ssh and ping . .. Mar 31 03:36:02 if you do not know what ssh is or how to use it . . yeah i sugget you pick up a good book on linux and start reading Mar 31 03:36:30 ( and ssh for that matter ) Mar 31 03:38:32 Curious though. if neither of you know much about this sort of thing, why are you getting these embedded devices ? Mar 31 03:39:02 dont worry, im not trying ot judge, just curious as to why Mar 31 03:42:11 Oh and yeah Thomas, Lynda.com has a few very good video topics on Linux CBT. very good bringing newbs, and rusty linux users up to speed :) Mar 31 03:44:21 m_billybob: i started on them as a way to do remote temp logging mostly... and gone from there trying to learn as i go along Mar 31 03:44:49 thomson_: ping that 192.168.7.2 from a windows cmd prompt Mar 31 03:45:13 tho started using ubuntu on a pc first, then RPi and now trying to move to a BBB to do even more stuff Mar 31 03:45:33 I started with them out of curiosity, to find out if/how they could be used in conjunction with amateur radio. Mar 31 03:45:38 remote temp logging eh ? Mar 31 03:46:04 thomspn_ sorry about the spelling of my last take on your nick lol Mar 31 03:46:14 kind of multi tasking atm Mar 31 03:46:25 yup, specifically temps for my back yard fishfarm Mar 31 03:46:32 cool Mar 31 03:46:50 which via cacti i get emailed when something is unhappy etc Mar 31 03:46:55 It would work for that but is kind of overkill Mar 31 03:47:06 and depending where i am.... can log in remotely and check things out Mar 31 03:47:11 but if you're not heavy into embedded stuff, its probably a very good place to start Mar 31 03:47:50 and now with the BBB i wana be able to remotely/automatically turn stuff on and off as well Mar 31 03:47:57 me . . . I have an adversion to arduino. But other thigns like an MSP430 could handle that job too, if all you're doing is loggign a couple temps Mar 31 03:48:36 I've also an interest in Linux in general. Never used it, but want to get away from windows. Mar 31 03:48:54 Got to get my feet wet somewhere, I suppose, right? Mar 31 03:48:59 sounds reasonable, if you do not like Windows, or MS Mar 31 03:49:30 ms always used to be the best home operating system imo... but its getting worse and worse Mar 31 03:49:41 Me, i have to have my Windows desktop PC. BUt ive also been using Linux ( Debian ) since the mid to late 90's Mar 31 03:50:24 "best" is subjective though. If you mean entertainment it probably still is, but Linux is gaining ground Mar 31 03:50:33 indeed Mar 31 03:50:39 hence my slowly moving to it Mar 31 03:50:56 Im still using Win7 enterprise Mar 31 03:51:02 now this is the only pc thats ms caus i play games, the htpc and laptops are both ubuntu Mar 31 03:51:13 win7 ultimate here Mar 31 03:51:25 pretty much the same thing differnt liscence though Mar 31 03:51:30 yup Mar 31 03:51:48 i did have ent installed a couple of times, just not currently Mar 31 03:51:56 There is of course notign wrong with using both. Mar 31 03:52:40 I've never used Win8, but I am very familiar with Win7 and I like it a lot, for what it is. Mar 31 03:52:47 I've learned more about Win8 than I planned on just by trying to figure out the BBB. Mar 31 03:52:50 i game too Mar 31 03:53:17 yea i cant see me bothering with win8... tho i have friends who swear by 8.1 Mar 31 03:53:33 One cause for that issue could be that since you reinstalled angstrom on the BBB, you may have to remove and then reinstall the drivers for the BBB Mar 31 03:54:03 its liek a COM miniport driver or something goes wacky when you change things Mar 31 03:54:50 You can try that and see if it works. But I would recommend if you're using Ubuntu that you install eitehr Debian or Ubuntu on your BBB Mar 31 03:54:52 Can't seem to find them, or I'd have done that already. I find it quite likely that that could be the problem. Mar 31 03:55:08 reboot into safe mode if win8 has one Mar 31 03:56:15 thats the problem with those miniport liek drivers, once the device is unplugged or unrecognized, they go missing. There is an option . . .you'd have to google search to show all drivers active or not in hardware manager Mar 31 03:59:18 thomson_, so what you could try if you're up to it. is gettign or using an existing uSD card, and installing Ubuntu on it and give it a go. It's been my personal experience that most Ubuntu users feel intimidated with Debian( probably the CLI interface ), but they're both basically the same Mar 31 04:01:59 And Angstrom? Comes up with a GUI. Probably best for me, since I haven't really used CLI since DOS 6.x Mar 31 04:02:45 if you wantto learn anyting you're going ot have to get your hands dirty on the command line. Tis why i mentioned the Linux CBT videos before Mar 31 04:03:01 ther is also youtube . . . Mar 31 04:03:08 tons of resources Mar 31 04:04:06 I'm actually really wanting to learn the CLI of linux. I took my win95 computer apart with a 12 gauge, didn't own a computer again for 15 years. Mar 31 04:04:21 heh Mar 31 04:04:35 oh while you're at it frind some vids on anger management :P Mar 31 04:05:01 12 guage, why didnt i ever think of that ;) Mar 31 04:05:44 lol Mar 31 04:05:44 heh... that wasn't it. I was a stupid teenager, caught doing things I shouldn't. So I removed the temptation. Mar 31 04:06:07 O.O Mar 31 04:06:14 Seriously though, once you start lernign Ubuntu / Debian, you'll get good at being able to find what you need in a hurry. Just takes time and practice. Mar 31 04:07:05 m_billybob: if your only going to use cli am i right in thinking that it wont really matter if i use debian or ubuntu on the BBB? Mar 31 04:07:11 thomson_: ping that 192.168.7.2 from a windows cmd prompt Mar 31 04:07:16 Thanks for the info. I really appreciate it. Mar 31 04:07:46 Dan it will matter some. I dont expect you under stand what I mean by this , but Debian uses a different init system than Ubuntu Mar 31 04:07:57 ahh ok Mar 31 04:08:07 mazzoo - I did, with no options, just "ping 192.168.7.2" and it returned 100% packet loss Mar 31 04:08:23 Probably not using Ping properly. Mar 31 04:08:26 then its not connected Mar 31 04:08:36 no what you typed is right Mar 31 04:08:43 in windows that will ping 4 times Mar 31 04:08:57 Linux it would ping indefinately until you CTRL C Mar 31 04:10:12 Dangit, I keep typing replies on the BBB command line. Got to move that keyboard. Yes, 4 pings, all timed out. Mar 31 04:10:16 you can also do ping 192.168.7.2 -t in windows which will keep it pinging till you tell it to stop...... which is good to have just barely visable while your screwing around with stuff, if you do osmething and get it right it will suddenly start sending you back pings Mar 31 04:10:34 or ping -n( amount ) Mar 31 04:11:05 i find i use -t a lot :) Mar 31 04:11:45 but yea if you cant ping the BB you have some connection issue, most likely in the windows driver id imagine Mar 31 04:12:09 The windows driver I can't (*@$*($&#@ find, of course. Mar 31 04:12:18 thomson_, try installing the drivers afresh Mar 31 04:12:20 tried just installing it again? Mar 31 04:12:25 heh snap Mar 31 04:12:40 can worry about removing the old drivers later, if the install package doesnt barf lol Mar 31 04:12:41 I tried installing again. Figure I must uninstall them first. Once I find the buggers. Mar 31 04:13:00 hmm Mar 31 04:13:08 replug the BBB Mar 31 04:13:42 Also try each and every USB port . . . on the off chance it requires a HUB port to be used. Mar 31 04:13:48 tried turning it off and back on again? Mar 31 04:13:56 ok, shutting it down. Mar 31 04:13:58 the laptop that is Mar 31 04:14:11 I did, also, restart the laptop, yes. Mar 31 04:14:29 Uh, I thnk I'll try that again though. Be back in a few... Mar 31 04:14:36 kk Mar 31 04:18:00 Ive had similar issues with otehr embedded devices using USB miniport drivers, when the device is not plugged into the first USB port on the HUB controller Mar 31 04:18:16 have no experienced this with the BBB yet though Mar 31 04:18:21 Ok. I'll try ping again, with the BBB in a different usb port Mar 31 04:19:00 Thomson if it is to work it'll show up as a mass storage device, so no need to try and ping until the mass storage device comes up Mar 31 04:19:57 you've got the blinking LEDs after abotu a minute once you bring the BBB up right ? Mar 31 04:21:11 Yeah, the leds come up. The whole thing boots, I've got it into another monitor. And it does show up as drive E in windows. Mar 31 04:22:09 so you can get to a terminal on the BBB ? Mar 31 04:22:29 Yes. Mar 31 04:23:21 OK so ill assume you have a keyboard connected too then. You can always try pinging the windows machine from the BBB Mar 31 04:23:37 how? Mar 31 04:23:58 you log into the BBB and type "ping 192.168.7.1" Mar 31 04:26:30 ping itself? destination host unreachable. Mar 31 04:26:45 ok so still no connection via gether Mar 31 04:26:47 does a default win7/8 firewall respond to icmp echo requests? Mar 31 04:26:52 gether Mar 31 04:27:14 mazzoo, should block by default no Mar 31 04:27:16 don't know, mazzoo. Mar 31 04:27:27 especially ifthere is a DHCP server running in software Mar 31 04:27:47 shold not block by default* Mar 31 04:28:34 so hmm Mar 31 04:29:01 wonder is lsmod would show anythign meaningful Mar 31 04:29:02 thomson: and you changed the physical usb port on the pc? Mar 31 04:29:18 (sounded like a good idea to me wrt windows) Mar 31 04:29:18 Yes. Mar 31 04:29:20 is/if Mar 31 04:29:21 meh Mar 31 04:30:00 Thomson, so you tried every usb port ? Mar 31 04:30:08 No. Mar 31 04:31:06 trying another now. Mar 31 04:31:48 if you have a single USB 3.0 port like I do that should be on a seperate HUB controller ( by its self ) Mar 31 04:32:50 you can tell if its USB 3.0 or not by the color of the little tab inside the slot. if it is blue then it should be a 3.0 port Mar 31 04:34:58 Any idea whick kernel version the Angstrom you have installed is using ? uname -a from the command line should tell all Mar 31 04:35:57 the one i have installed is still 3.8.11 i think, I netboot my BBB Mar 31 04:37:36 no, it's white. I've tried all the ports, ping comes back negative. I've got to hang it up for tonight. That website was Lydia.com, you said? Mar 31 04:39:20 thomson yes, but that wont fix this issue Mar 31 04:39:31 lynda.com Mar 31 04:40:14 Yes, but all knowledge is welcome. This issue has to be benched for today. Thank you for your assistance, though. Mar 31 04:40:21 Hope to see you around again. Mar 31 04:40:23 get on the googlegroups and ask how to fix this issue, ive no idea which kernel version the latest angstrom uses Mar 31 04:40:45 or how the rootfs is setup by default Mar 31 04:42:50 hmm the vids im thinking of may not be on lynda.com Mar 31 04:45:19 heh its actually cbtnuggets.com Mar 31 07:34:02 * N3wbs is back (gone 62:31:49) Mar 31 07:44:15 Hi to all Mar 31 07:44:35 i'm trying to activate uart1, 4 and 5 with rts cts lines Mar 31 07:45:00 i make a mod in the dts file to mux the pins but i can get it work Mar 31 07:45:05 anyone can help me? Mar 31 07:45:10 error message? Mar 31 07:45:13 what have you done? Mar 31 07:45:20 where is my chocolate? Mar 31 07:45:25 lol Mar 31 07:45:26 xD Mar 31 07:45:59 paela would be ok as well ;) Mar 31 07:46:44 KotH this is dmesg output Mar 31 07:46:46 http://pastebin.com/K0AvjN6L Mar 31 07:47:33 and this is the dts for uart1 Mar 31 07:47:36 http://pastebin.com/6F1WJ6C5 Mar 31 07:53:11 you are using overlays.. have you checked whether uart is not alrady configured? Mar 31 07:53:17 whether something else uses the pins? Mar 31 07:53:24 whether the pinmux is correct? Mar 31 07:53:50 [ 35.169659] omap_uart 481aa000.serial: did not get pins for uart5 error: -19 Mar 31 07:53:58 sounds like something is using those pins already Mar 31 07:55:30 KotH cat to slots says nothing is using it Mar 31 07:55:58 http://pastebin.com/CYFBYPLK Mar 31 07:56:40 you can somehow extract the currently running DT from the kernel. use that Mar 31 07:59:00 the pingroups Mar 31 07:59:24 http://pastebin.com/Qn0sCN0d Mar 31 08:01:12 * KotH has no time to check the numbers Mar 31 08:22:34 hi good morning Mar 31 08:23:23 i'm trying to use some boards troght an usb-serial rs485 cable ... Mar 31 08:23:49 ... it works... but only some seconds xD Mar 31 08:24:23 then the usb-serial hangs , and i loose the serial port. Mar 31 08:24:42 something is wrong with ftdi_sio module?? Mar 31 08:25:01 i'm using debian wheezy flashed into the emmc Mar 31 08:25:10 the beaglebone doesn't have rs485 Mar 31 08:26:03 mmmm i'm using an usb-rs485 ftdi cable Mar 31 08:31:57 tbr are you saying that the beaglebone does'nt have rs485 support in the ftdi_sio module? Mar 31 08:33:01 astrapotro: I'm saying that the board doesn't have a physical RS485 port. if you add one by USB it's just another port... Mar 31 08:33:16 astrapotro: does that usb device work on a linux desktop? Mar 31 08:33:32 yep Mar 31 08:33:54 on a wheezy laptop and in the raspberrypi Mar 31 08:33:58 like a charm Mar 31 08:35:39 with the beagle some seconds and the serial port goes to /dev/null xD Mar 31 08:35:39 how are you powering the BBB? Mar 31 08:36:31 i'0m powering it trought an 5v 2A powered hub with an usb-miniusb cable Mar 31 08:37:01 is the same installation that i'm using in my project qith some raspies Mar 31 08:37:03 please power it directly through the barrel connector Mar 31 08:37:34 aham, so do you think it can be a power supply problem? Mar 31 08:37:52 i'll try it, thanks tbr Mar 31 08:37:52 no, I'm giving you hints how to rule out problem sources Mar 31 08:38:05 powering the board properly certainly doesn't hurt Mar 31 08:39:26 ok Mar 31 08:40:19 maybe someone has tried to use usb-serial hardware and has suffered the same problem Mar 31 08:41:10 woot just isolated adc bug, hopefully gets fixed soon Mar 31 08:42:22 wath's adc bug? Mar 31 08:43:30 takes X readings to get the proper value from the adc pin where X is the number of pins you've read from Mar 31 08:44:00 patch 19 to adc that tried to incorporate continious sampling broke it Mar 31 08:44:13 astrapotro: btw, why are you trying to use such a problem prone setup anyway? The BBB has a pile of UARTs. You could just add a RS485 transceiver and be done with it. Mar 31 08:45:18 tbr: is there a list of kernel versions and musb problems? Mar 31 08:45:37 it could be a solution, but i would like to maintein the same installation that i've in my project qith the raspies Mar 31 08:47:01 astrapotro: it might also be a kernel problem Mar 31 08:47:11 astrapotro: it is known that old kernels had problems with usb on the bbb Mar 31 08:47:17 which ones, i dont know Mar 31 08:47:41 what is the problem with USB<-> serial ftdi cables? they usually work under debian 386 or x64 Mar 31 08:48:16 diego_: I've seen FTDI be _very_ unstable on linux under certain signal conditions Mar 31 08:48:25 it was a general problem with usb on the bbb. the hardware driver had bugs Mar 31 08:49:13 tbr: that's mostly because people dont read the datasheet and provide the wrong signal levels, no proper buffer caps etc pp Mar 31 08:49:29 correct Mar 31 08:49:32 tbr: but yes, other than that, ftdi sucks... but it still works, if you do the hardwaree right Mar 31 08:49:49 but we know nothing about the person's ftdi-rs485 contraption Mar 31 08:50:02 also the BBB is powered through USB Mar 31 08:50:11 baaaaad idea Mar 31 08:50:18 i'm using this kernel: 3.8.13-bone30 Mar 31 08:50:23 rs-485 cables use a lot of power Mar 31 08:50:37 and it's with lots of spikes too Mar 31 08:51:03 I tried suggesting powering it properly, but they prefer to look "for people who did xyz" instead Mar 31 08:51:50 another option might be to connect a powered hub to the BBB to "buffer" the consumption of that converter Mar 31 08:52:05 generally, experiment until you narrow down the problem Mar 31 08:52:19 then reassess and implement proper remedies Mar 31 08:52:33 people usually skip the last step and wonder why things break Mar 31 08:53:02 i remember that with the raspberrypi i had some troubles with the ftdi cable, but i get to an stable situation downgrading the usb port speed Mar 31 08:53:20 that did the trick Mar 31 08:53:57 maybe the problem is the same qith the beagle Mar 31 08:55:43 astrapotro: very unlikely Mar 31 08:55:47 astrapotro: very unlikely Mar 31 08:56:22 astrapotro: also, if really usb speed was the problem, then the problem would be the rpi, not the usb cable. hence the problem would not cross over to the bbb Mar 31 08:56:43 maybe i should start a career to teach people basic problem solving in electronics Mar 31 08:56:47 there must be tons of money in it Mar 31 08:57:26 ok, i just thinking maybe the beaglebone has the same hard problem with the usb hub Mar 31 08:57:39 the problem is the bbb usb host driver is quite crappy Mar 31 08:59:14 good to know, c10ud Mar 31 08:59:27 KotH you can do a try and become a richer man. But not with me :-P Mar 31 09:01:38 c10ud: that should be fixed by now, shouldnt it? Mar 31 09:02:20 KotH, I wish: http://pastebin.com/kKniMB4p Mar 31 09:02:29 this is like, 5 mins ago Mar 31 09:03:10 with kernel 2.6.1 ? Mar 31 09:03:39 (7:26:44 PM) KotH: maybe i should start a career to teach people basic problem solving in electronics <--- ive found people either get it or they dont... and usually the ones who dont wont ever Mar 31 09:03:54 some (most?) people just arent logical Mar 31 09:03:58 KotH, 3.8.13bone41 and 3.13 Mar 31 09:05:57 it's kind of weird, doesn't happen everytime but still, sometimes it happens Mar 31 09:06:04 Dan1: it doesnt matter if they dont get it, as long as they pay me Mar 31 09:06:18 c10ud: hmm... Mar 31 09:09:04 USB is a pain especially when you have a long-term problem (ie something that appears every 1-2 days) Mar 31 09:10:03 teralaser: also fun: improper power supply and vendor blaming it on "crappy linux driver", even when confronted with the fact that soldering a dozen capacitors solves the problem Mar 31 09:10:41 nah, I don't think this is the issue Mar 31 09:10:45 (and calling me an idiot in the process) Mar 31 09:10:51 USB power supply can also be a pain, but that is much more tangible. Mar 31 09:10:53 i have a 100u between usb 5v and gnd Mar 31 09:11:01 and I have a reliable supply Mar 31 09:11:07 c10ud: i'm not talking abou tthe bbb, but a company that starts with soe and ends with kris Mar 31 09:11:30 c10ud: 100u is not much, especially when you have devices that have >1A peak power Mar 31 09:11:50 c10ud: also, X5R vs tantal vs alu Mar 31 09:12:02 The USB spec dictates the max capacity on the device side. Mar 31 09:12:27 yeah right, and how many people actually follow the specs? Mar 31 09:12:28 well according to bbb mailing list I shouldn't even have to put a capacitor in there Mar 31 09:13:27 c10ud : You could try changing either side with something else (e.g. another operating system, another driver, another IC ...) Mar 31 09:13:45 usually the fastest way. Mar 31 09:14:16 if it is your own contraption don't rule out signal integrity issues. Mar 31 09:14:25 hi! Mar 31 09:15:29 I think I'll just hope for the best until TI pushes out a better driver :) btw- the issue that annoys me most is the hard lock due to PNG decompression (!) Mar 31 09:49:05 So I have been having a hard time trying to grasp how to work with the ggpio pins. I have figured out how to export them through the command line and how to even somewhat export pwm pins, not sure what pin was exported. I am basically needing to get pins 41-46 on the 98 header enabled. 41-44 as outputs and 45-46 as pwm pins to control dc motor speed. I was considering the adafruit bbio library as i was getting frustrated but wanted this to be strictly a c/ Mar 31 09:49:05 c++ project Mar 31 09:50:12 are there any resources one can recommend for getting started with the gpio pins. It would be nice to see more tutorials on working with different devices and the beaglebone black. If I am able to get this working i may need to write a tutorial Mar 31 09:53:03 heh im writing a ruby library now Mar 31 09:53:09 just finished gpio/pwm/analog stuff Mar 31 09:53:12 gpio is simple Mar 31 09:53:18 direction file contains in/out Mar 31 09:53:22 then 1 or 0 for value Mar 31 09:53:33 you just need the mapping of gpio #'s to pin #'s Mar 31 09:54:02 http://www.digikey.com/~/media/Images/Article%20Library/TechZone%20Articles/2013/September/BeagleBone%20Black%20Brings%20Arduino-Style%20Connectivity%20Simplicity%20to%20Embedded%20Linux/article-2013september-beaglebone-black-brings-arduino-fig3.jpg Mar 31 09:54:22 keep in mind you cant use 45-46 Mar 31 09:54:31 unless you do not load the hdmi cape Mar 31 09:54:35 which is enabled by default Mar 31 09:54:42 see /boot/uboot/uEnv.txt Mar 31 09:55:08 http://pix.cs.olemiss.edu/csci581/BBBlackGPIOMap.png Mar 31 09:55:10 may be helpful Mar 31 09:56:08 oh i like that last one Mar 31 09:56:15 ive been looking for something like taht Mar 31 09:56:22 nyt-, pins that i will be using is it necessary to export them at boot time or should my program be exporting them every time it runs? Mar 31 09:56:35 only need to be exported once Mar 31 09:56:38 whatever you prefer Mar 31 09:56:56 the problem you'll run into is trying to use the pins on p8 Mar 31 09:57:00 from 27 to 46 Mar 31 09:57:03 since theyre used by hdmi Mar 31 09:57:24 also do not ever use the mmc clock or cmd pins Mar 31 09:57:28 even with emmc diabled Mar 31 09:57:50 so i should be looking at using pins on the p9 header then Mar 31 09:58:24 from your diagram i see some on the p8 header that can be used Mar 31 09:59:18 yes Mar 31 09:59:19 just saying Mar 31 09:59:21 the ones you specified Mar 31 09:59:25 are normally occupied by hdmi Mar 31 09:59:32 so how would i export a pwm pin? I was looking at the bbio library which seems to be c with some embedded python. seems like it should be simple to port the python parts to c Mar 31 09:59:33 you can disable that if youre not using by editing uEnv Mar 31 09:59:48 echo 30 > /sys/class/gpio/export Mar 31 09:59:51 to export gpio_30 Mar 31 10:00:03 which translates to P9_11 Mar 31 10:00:06 34 and 36 will be fine for me Mar 31 10:00:33 gpio 34 and 36? Mar 31 10:00:36 or header pins 34 and 36? Mar 31 10:00:42 that will be a serial port. is there a difference for a pwm pin Mar 31 10:00:53 because gpio 34 and 36 you'll need to disable the onboard emmc Mar 31 10:00:53 header pins on the p8 header Mar 31 10:01:05 34 and 36 are analog inputs Mar 31 10:01:06 not gpio Mar 31 10:01:11 look at the image i linked you Mar 31 10:01:16 err p8 is on the right Mar 31 10:01:16 nm Mar 31 10:01:28 you'll have to disable emmc to use those pins Mar 31 10:01:32 otherwise they control the onboard emmc Mar 31 10:01:49 as with the rest of the pins in that last image that are yellow Mar 31 10:01:52 this is fine if you boot off sd Mar 31 10:01:56 which is faster anyway Mar 31 10:02:17 your looking at the p9 header. on the p8 header from the diagram you sent, 34 and 36 would be pwm Mar 31 10:02:32 ah looking at the gpio #'s Mar 31 10:02:35 damn this laptop Mar 31 10:02:37 im vnc'd to my desktop Mar 31 10:02:42 so i have a really small window Mar 31 10:02:50 34 and 36 you can use as pwm or gpio Mar 31 10:02:57 my last question would be how does the pin modes come into play? Mar 31 10:02:59 as long as you do not load the hdmi cae Mar 31 10:03:01 cape Mar 31 10:03:10 loading dtbs activates the capes Mar 31 10:03:29 i know the pwm pins need to be in mode 3 and gpio mode 7 Mar 31 10:03:36 how is this specified and where Mar 31 10:04:35 echo am33xx_pwm > /sys/devices/bonecape_mgr.*/slots Mar 31 10:04:40 to enable the pwm controller Mar 31 10:04:42 then per pin Mar 31 10:04:53 bone_pwm_P8_36 Mar 31 10:04:56 into slots as well Mar 31 10:05:25 http://i.imgur.com/deypWoY.png Mar 31 10:05:28 was just doing this yesterday Mar 31 10:05:59 was cruising along with this ruby lib nicely until i ran into the stupid adc bug Mar 31 10:06:41 what adc bug is this? Mar 31 10:06:58 takes X reads to get the current value where X is the number of pins you've read from Mar 31 10:07:19 was introduced with patch 19 to adc where they were implementing continuous sampling Mar 31 10:07:33 s/pins youve read from/adc pins youve read from/ Mar 31 10:08:05 anyway Mar 31 10:08:07 hope that info helps you Mar 31 10:08:15 took me a while to dig up Mar 31 10:08:21 since so much of the old methods are still floating around Mar 31 10:08:23 its definitely a good start Mar 31 10:08:26 and documentation is not in one place Mar 31 10:08:30 and lacking severely Mar 31 10:09:14 nyt-: ive copied all that down..... im about to need a lot of that info in the next few days i think :) Mar 31 10:10:13 can't wait to have this ruby lib finished Mar 31 10:10:15 and start making nice stuff Mar 31 10:10:17 have some ideas already Mar 31 10:14:50 ok going to sleep, gl Mar 31 10:15:13 thnks again nyt- Mar 31 10:17:46 is it possible to power the BBB from the P8/P9 headers? Mar 31 10:21:13 power to vdd5v pin Mar 31 10:21:39 err Mar 31 10:21:40 sys5v Mar 31 10:21:53 no Mar 31 10:21:54 right the first time Mar 31 10:21:56 vdd 5v pins Mar 31 10:21:59 you can power those Mar 31 10:22:03 and give it ground Mar 31 10:22:06 and youre good to go Mar 31 10:22:22 P9 5&6 Mar 31 10:22:34 then ground on p 1&2 Mar 31 10:22:53 cool Mar 31 10:23:17 thanks nyt- Mar 31 11:08:34 hiiiiiiii Mar 31 11:09:11 which player are use in this board Mar 31 11:09:47 ???????????? Mar 31 11:10:45 any budy help me Mar 31 11:12:38 Guest4031: what do you mean? Mar 31 11:13:14 i use this board Mar 31 11:13:27 i want to play media Mar 31 11:13:43 which distribution do you run on the board? Mar 31 11:13:55 but i dont know which player use Mar 31 11:13:58 Guest4031: go buy a raspberry pi Mar 31 11:14:00 yes Mar 31 11:14:14 Guest4031: it haz fullhd playback and is supa 1337 Mar 31 11:14:29 i have already use thisraspi Mar 31 11:14:31 that's about the only thing it's good at Mar 31 11:14:59 Guest4031: we do not have media playaz Mar 31 11:15:02 to spell this out clearly: the BBB does not have hardware accelerated decoding, so everything will happen in the CPU Mar 31 11:15:07 Guest4031: we only have GPIO Mar 31 11:15:40 so if you are looking for full screen media playback and a media center, this IS the wrong board Mar 31 11:16:38 but in raspberry pi my media not play in sequence............. Mar 31 11:16:54 your keyboard is broken, you might need to fix that. Mar 31 11:16:59 Guest4031: and you do really think that picking another board will fix that? Mar 31 11:17:20 yes Mar 31 11:17:27 Guest4031: go tell the media player folks want you want. you do NOT want a beagleboard. Mar 31 11:17:32 i think Mar 31 11:17:35 no. Mar 31 11:17:38 i disagree. Mar 31 11:18:36 if a RPi cant do it... a BBB is going to do it worse... Mar 31 11:18:41 but why? Mar 31 11:18:52 caus thats how things work Mar 31 11:18:59 BBB has no GPU accelleration Mar 31 11:19:05 Guest4031: do you even know what you are talking about? Mar 31 11:19:11 BBB's were never designed to do something like media, its for other sorts of thing Mar 31 11:19:40 Guest4031: if yes, then please explain in one sentence what the order of playing some media files in some player software has to do with the underlying hardware. Mar 31 11:19:52 Guest4031: we're all listening. Mar 31 11:20:14 ok Mar 31 11:20:16 same as you can use chopsticks to eat ice cream if you want to.... but its going to suck doing it Mar 31 11:20:55 Dan1: no, its more like "eating icecream with chopsticks is hard, will picking another chopstick brand fix it?" Mar 31 11:22:31 and the correct answer is "tell the chopstick manufacturer to shape their chopsticks like a spoon. or just grab a spoon." Mar 31 11:22:52 with the latter being the most sensible option. Mar 31 11:23:27 * tbr hands out free icecream spoons Mar 31 11:23:46 any suggestions about player to play media without gape Mar 31 11:23:58 in raspi Mar 31 11:24:03 Guest4031: no. Mar 31 11:24:13 Guest4031: we are _NOT_ a media player channel Mar 31 11:24:16 in linux Mar 31 11:24:24 Guest4031: we are _NOT_ a raspi channel Mar 31 11:24:34 buy a PC and run ubuntu? Mar 31 11:24:35 ah -- maybe I found how to mitigate the usb issue -- disabling auto suspend. Do you know why the kernel command line doesn't work? Mar 31 11:24:48 then head over to #ubuntumediaplayer Mar 31 11:25:11 Guest4031: so if your next question does not include a clear, meaningful reference to the topic of this channel (the beagleboard family) - please leave. or be left, then. Mar 31 11:25:46 I'd really want to avoid rebuilding the kernel today :\ Mar 31 11:25:54 why Mar 31 11:26:33 because. Mar 31 11:45:36 c10ud: no kernel build today, kernel build tomorrow, there is always a kernel build tomorrow Mar 31 11:46:00 thank god there are RCN's scripts Mar 31 11:46:33 but still - kernel documentation not working is something I didn't witness yet Mar 31 11:47:54 you are new to linux, are you? Mar 31 11:48:31 KotH, let's say I like to run prebaked-generic kernels Mar 31 11:49:47 probably not what the hardcore linux geek expects, but ubuntu kernels work really good, I had to change a kernel command line like once in 8 years... Mar 31 11:49:56 now, arm socs are different but.. Mar 31 11:50:14 c10ud: most of the hardcore lunux geeks i know use distro kernels these days Mar 31 11:50:41 i have my own kernel Mar 31 11:50:45 but then, the hard core linux geeks are a dying race Mar 31 11:50:53 heh Mar 31 11:50:56 with grsec/pax and no loadable module support Mar 31 11:51:01 killed one by one buy those ubuntu zombies Mar 31 11:51:21 single 5.3MB kernel Mar 31 11:51:47 10 years ago you could fit whole distro with X on 2 floppies Mar 31 11:52:18 anyway, I thought usbcore.autosuspend wasn't exactly like rocket science Mar 31 11:52:56 jacekowski, you can get 50mib distros afaik, but you cannot find < gigs sd cards :) Mar 31 11:53:49 jacekowski: i remember building my own boot floppies. single floppy with kernel and rootfs Mar 31 11:54:21 c10ud: the problem is that you are exercising a code path that few people use Mar 31 11:54:48 c10ud: it worked for sure somewhen, but at some point in time a bug got introduced. and nobody discovered it, yet Mar 31 11:55:09 well not according to google though Mar 31 11:55:24 anyway, now I'll just CONFIG_USB_SUSPEND=n *sighs* Mar 31 13:00:41 well, FYI CONFIG_USB_SUSPEND=n makes no difference, yay Mar 31 13:01:42 Good morning guys, I need some help. I have been searching and triyng to figure out the best way to export pins for usage. I have so far seen how to export standard gpio pins through the cli which isnt too hard. How do i go about exporting pwm pins? I will be using 4 pins as outputs for a hbrige and 2 pwm pins for speed control of the motors. How do i go about getting these pins setup for use? Mar 31 13:02:29 mistawright: look at the examples for the baconcape, they should contain exactly that. Mar 31 13:10:57 LetoThe2nd, are these examples in c/c++? I'm looking at the elinux.org webiste and do not see anything specific to the bacon cape on the baconcape reference material section Mar 31 13:12:46 mistawright: its a dtbo basically, and then sysfs nodes as usual. Mar 31 13:15:34 LetoThe2nd, ok so as long as I use the dts file the pins will be in the state necessary on boot? Mar 31 13:16:30 Hi All Mar 31 13:16:46 how the beagle bone boot up with barebox Mar 31 13:17:38 maybe ask the bareboy people? Mar 31 13:17:42 why not use uboot? Mar 31 13:18:03 mistawright: i fail to understand the question. Mar 31 13:18:24 I am try to study barebox, and see it is supported by barebox Mar 31 13:18:40 av500: I will try, thanks Mar 31 13:23:07 LetoThe2nd, my question was with the bacon cape dts file I should already have pins exported for gpio and pwm use? Mar 31 13:26:53 mistawright: yes. Mar 31 13:29:54 av500: I try u-boot, however it can not boot up Mar 31 13:30:09 I'm sure it can Mar 31 13:30:14 I have seen it Mar 31 13:30:26 u-boot 2014.04-rc2 with am335x_evm configuration Mar 31 13:30:41 copy MLO and u-boot.img to TF card Mar 31 13:31:05 it always show up u-boot SPL, while not enter into u-boot Mar 31 13:31:27 any idea about it? Mar 31 13:32:29 pastebin a full boot log Mar 31 13:32:34 www.pastebin.com Mar 31 13:33:23 sorry, can not access pastebin.com Mar 31 13:33:41 it always show up: U-Boot SPL 2014.04-rc2-00091-g0b2da7e (Mar 31 2014 - 21:21:17) Mar 31 13:33:49 repeat it again and again Mar 31 13:38:25 thought this was interesting others might as well, http://eskimon.fr/beaglebone-black-gpio-interactive-map Mar 31 15:11:13 Anyone familiar with the timers you can put into a 120V outlet to switch lights on/off? I'm looking for something similar that switches the 5Volts on a USB cable. I want to use a switch like this to power on/off a BBB for a few hours every night, in order to extend battery life. Is there a name for this kind of timer? I'm having problems googling for such a device. Mar 31 15:13:31 get an microcontroller and a relay Mar 31 15:13:40 tbr: ++ Mar 31 15:14:03 one of those micro/nano/whatever-duino clones should totally suffice Mar 31 15:14:19 IIRC I saw one that was latched to a relay once Mar 31 15:15:39 iandow: https://duckduckgo.com/?q=timeswitch!gi and a relay if u want an off-the-shelf build Mar 31 15:18:21 hmmm, most of the off-the-shelf builds are based on 120V input / output. I need a USB 5Volt inteface. Mar 31 15:20:59 iandow: You know those 120V ones draw some power from the line to run the timer, right? Mar 31 15:21:02 thats the relay for Mar 31 15:21:25 myself: oh, microcontrollers don't? Mar 31 15:21:46 they also need power, all of them Mar 31 15:21:48 mazzoo: my point is, the "Saving battery" is only gonna come if the timer draws less power than the device being timed. Mar 31 15:22:15 myself: yea, but it's a tiny amount. My project can tolerate that kind of draw 24x7 Mar 31 15:23:05 Less than a BBB fully running, anyway. Mar 31 15:23:33 what sort of interface do you want to set the timing cycle? Seems like an RTC chip with an interrupt output should be all you need. Mar 31 15:24:06 question is whether the BBB has an easy way to wake it by such a pin Mar 31 15:24:13 Something like this would work well, but their referenced URL is broken. http://www.raspberrypi.org/forum/viewtopic.php?f=93&t=54653 Mar 31 15:24:46 amusing Mar 31 15:24:52 the timer module runs from battery or sometihng? Mar 31 16:40:32 Can a BBB be powered by 12V instead of 5V, or would that fry it? Mar 31 16:40:36 I'm trying to use a TP-Link TL-WN722N wireless adapter on my BBW but after a few minutes of it being in monitor mode the BBW just hangs until I disconnect the adapter. I'm currently powering it via a USB cell phone charger. Do you guys think my problem is related to power consumption? Mar 31 16:42:33 xa0z: nope probably not power. I tried for a long time to get the WN722N to work. It got it to work temporarily, but the BBW it would always go down after 30 minutes. Maybe related to some power management feature, but I couldn't find the root cause, so I just bought a BBB, which works much easier. Mar 31 16:43:07 That's a bummer. Mar 31 16:43:37 Did you try with a powered USB hub? Mar 31 16:46:28 I read on a raspPI forum that the WN722N uses a lot of power and causes issues, so I wasn't sure. Mar 31 16:48:56 TL-WN722N, TL-WN722NC (ath9k_htc device with htc_9271.fw file from http://linuxwireless.org/download/htc_fw/1.3/htc_9271.fw); needs powered USB Hub (B) Mar 31 16:54:48 iandow: you can do that exactly once, then you need to buy a new board. Mar 31 16:54:52 short answer: no Mar 31 16:55:09 thanks Mar 31 16:55:27 unless I can push all the smoke back in, at least. ;-) Mar 31 16:58:36 I recently ordered a BBB board from special computing. As per the instructions, I connected it to my computer and tried to open START.htm. However, nothing was shown in the browser. When I checked that file on command prompt, it seems that the file size is zero. Also all the other files on that mounted disk have file sizes equal to zero. Has anyone else faced this problem? Mar 31 17:12:10 Guest39825: sounds strange Mar 31 17:12:22 Guest39825: you could always reflash to the latest image Mar 31 18:27:48 somebody recently reported that here Mar 31 18:57:01 Bryanstein: ping Mar 31 19:34:51 can someone tell me the max clean gpio frequency Mar 31 19:40:44 matt_____: before someone answers, maybe you could tell us what you are trying to accomplish? Mar 31 19:56:35 PWM comes to mind . . . Mar 31 19:57:08 Just looking at some questions peopel have abouttheir BBB, I have come to relize im virtually an expert :/ Mar 31 20:04:53 m_billybob: so why would you want to do pwm with a gpio? that is not a good use of resources Mar 31 20:05:58 Not what I meant. Just mean that if i require a freq thats high id probably use PWM instead, or perhaps the PRU's Mar 31 20:17:36 matt_____: few khz, but its not going to be clean like pwm Mar 31 20:25:42 hey guys, just a quick question, if im power the beaglebone black over the usb with 5v 2a, will buying the DC charger (at 2A rather than 1) really make a difference? Mar 31 20:26:51 you're asking if the board would mind having inadequate power available? Mar 31 20:28:33 i wasnt sure, the wats would be the same, wouldnt? im using a wall plug at dv 5v 2a Mar 31 20:29:07 dc 5v 2a is dc 5v 2a one way or another isnt it? Mar 31 20:34:37 the difference is though how you attach it Mar 31 20:34:55 I seem to remember, that the board behaves different if it sees the power from USB Mar 31 20:35:04 e.g. lower CPU frequency Mar 31 20:37:15 okay, that would explain my problem, i ran a minecraft server on my pi before it broke and tried running it on the black with the same settings, on debian, it pretty much just crumbled. So thanks Mar 31 20:45:09 it really runs at a lower clock speed over usb? Mar 31 20:49:14 tbr that is incorrect Mar 31 20:49:58 running cpu frq shows my board is running at 1ghz Mar 31 20:50:02 CPU should be ondemand governor, whcih is 300Mhz at idle and on up to 1Ghz loaded Mar 31 20:50:03 even over the usb Mar 31 20:50:35 or perhaps this is different form image to image Mar 31 20:50:55 root@rbone:~# cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq Mar 31 20:50:55 1000000 Mar 31 20:50:56 yeah ive been powering my BBB via USB since june ish last year Mar 31 20:50:57 i am on debian 7.4 if that matters Mar 31 20:51:02 always been ondemand Mar 31 20:51:19 7.2 here for now Mar 31 20:51:45 custom kernel and rootfs Mar 31 20:51:48 odd, the bbb should be much faster than the pi, wonder why it can hardly run the server Mar 31 20:51:55 because Mar 31 20:51:58 you only have 512mb of memory Mar 31 20:52:04 and minecraft is a pig Mar 31 20:52:05 BBB is faster than the PI Mar 31 20:52:08 pi has 524 Mar 31 20:52:17 and it cant run it well either whats your point Mar 31 20:52:34 that the pi was significantly better Mar 31 20:52:44 use a different jre? Mar 31 20:52:57 im using the most current Mar 31 20:52:59 or use HF binaries . . . Mar 31 20:53:10 hf might be the problem Mar 31 20:53:15 hf? Mar 31 20:53:19 hard float Mar 31 20:53:23 hard float Mar 31 20:54:04 i seriously doubt that hf is the problem id imagine the devloper(s) would be the most likely culprit Mar 31 20:54:09 it sometimes gives the error it cant access low level api buffers, is that why? Mar 31 20:54:40 cant access buffers sounds like mem issue Mar 31 20:54:45 not sure how fp intensive mc is but it may be an issue Mar 31 20:55:46 im assuming theres probably no easy fix then.. Mar 31 20:56:14 i have no idea concerning MC or anythign java related Mar 31 20:56:25 im alergic to JRE Mar 31 20:56:34 well Mar 31 20:56:37 im using debian 7.4 Mar 31 20:56:40 and all the packages are from armhf Mar 31 20:56:54 whats a armhf ? Mar 31 20:57:01 you mean dot com ? Mar 31 20:57:03 arm hard float Mar 31 20:57:38 "packages are from armhf" hints at a place, bot a thing Mar 31 20:57:39 /etc/apt/sources.list:deb [arch=armhf] http://beagle.s3.amazonaws.com/debian wheezy-bbb main Mar 31 20:57:42 \ Mar 31 20:57:46 not a thing* Mar 31 20:57:54 it hints that theyre using the armhf dist Mar 31 20:58:47 thats RCN's repo Mar 31 20:58:51 give me a sec, ill print off the exact error Mar 31 20:58:57 or looks very much like it Mar 31 20:59:19 yes its the official debian repo, showing its using armhf architecture Mar 31 20:59:20 * nyt- sighs Mar 31 20:59:23 try a different jre Mar 31 20:59:29 are you using openjdk or sun? Mar 31 20:59:50 i dont even know whats available on this arch Mar 31 20:59:55 but you might try openjre 6 Mar 31 21:00:20 apt-cache search . . . Mar 31 21:00:32 i installed the default jre..

Mar 31 21:01:45 java -version java version "1.6.0_27" OpenJDK Runtime Environment (IcedTea6 1.12.6) (6b27-1.12.6-1~deb7u1) OpenJDK Zero VM (build 20.0-b12, mixed mode) debian@arm:~/bukkit$ Mar 31 21:01:51 try 7 then Mar 31 21:01:59 So, it wants a kernel drivers for a flipping game server ? Mar 31 21:03:13 im a bit of a beginner, is that what it is referring to? Mar 31 21:03:52 Your platform does not provide complete low-level API for accessing direct buffers reliably <- rather vague Mar 31 21:04:17 exactly, my problem Mar 31 21:04:40 system unstability. <-- lvoely grammar too Mar 31 21:04:47 lovely lol Mar 31 21:04:51 im the one to talk . . . Mar 31 21:04:54 wonder if the version on the pi used the GPU? Mar 31 21:05:18 GPGPU ? Mar 31 21:05:32 no, the gpu is broadcoms, they hadnt released the drivers Mar 31 21:05:47 or anyway to use the gpu like that Mar 31 21:05:53 the GPU was mali400 afaik but i dont own a PI Mar 31 21:06:11 mine broke, thats why i bought a BBB Mar 31 21:09:07 btw Mar 31 21:09:09 that log message Mar 31 21:09:11 isf from netty Mar 31 21:09:22 if (!hasUnsafe()) { Mar 31 21:09:22 80 logger.info( Mar 31 21:09:22 81 "Your platform does not provide complete low-level API for accessing direct buffers reliably.

Mar 31 21:09:56 because its using io.netty Mar 31 21:10:00 which is wanting sun jdk Mar 31 21:10:29 so i need a new verison Mar 31 21:12:05 i see a package for openjdk7 which may be worth trying, otherwise you might be sol, what java was running on your rpi? Mar 31 21:12:49 im assuming 6, it wasnt officially a release when i was running it, it might have been 7 though Mar 31 21:12:58 guesses dont help =[ Mar 31 21:13:03 try installing openjdk7 see if it helps Mar 31 21:13:30 i have both installed, i just noticed.. could the problem be a confliction? Mar 31 21:15:38 read a post on stackoverflow that hinted at raising the memory limit for netty Mar 31 21:15:39 perhaps i should remove jdk6 Mar 31 21:16:07 seems to be a problem several peopel are having i did not see a fix though Mar 31 21:16:33 okay well its good to know im not the only one, i tried looking for it online but couldnt find anything Mar 31 21:16:51 google search your error message you'll find the same stuff i did Mar 31 21:16:59 how would i raise the memory allowances for netty? Mar 31 21:17:05 okay thanks Mar 31 21:17:06 Your platform does not provide complete low-level API for accessing direct buffers reliably <---- is what i searched Mar 31 21:19:34 oh well, guess ill just lurk around, thanks guys Mar 31 21:19:35 everyone with the isue seems to be running debian, so i do not think it is a platform / arch issue Mar 31 21:20:10 yeah, must be a version problem, its what it seems like Mar 31 21:20:30 openJDK has been known to be flaky in some cases Mar 31 21:21:01 i really dislike java to begin with, haha this sure didnt help Mar 31 21:21:34 Last year i was setting up java for Linux for some reason i dont recall ( another embedded device perhaps ) and ran into a few semi related issues Mar 31 21:22:21 Yeah, I abosolutely refuse to run JRE on my windows boexen Mar 31 21:22:29 boxen* Mar 31 21:23:31 well thanks for the info Mar 31 21:23:46 np, and not like I was much help lol Mar 31 21:47:54 I have definitely see openJDK be flaky and once replaced by official Oracle release... problem gone. Mar 31 21:58:03 I am looking at step/ direction for stepper drivers Mar 31 23:15:01 hi.. I've got a problem with a kernel (I'm using http://beagleboard.org/linux to build): it works nicely if I boot it from tftp. If I copy it on the SD it hangs after "booting the kernel". The command line has been set in uEnv.txt and enables using the eMMC as the root partition. Any hints? Mar 31 23:39:14 dwery: I've not done it myself, but normally kernel on block device requires some bootloader tweaking Mar 31 23:40:24 I guess it has something to do with the dtb Mar 31 23:41:36 I'm planning on buying a bbb soon, but haven't Mar 31 23:46:12 Okay, using the BBW and a TP-Link TL-WN722N, using a powered USB hub works fine. Mar 31 23:46:35 Without the powered USB hub, the wireless device seems to kill the BBW by drawing too much power. Mar 31 23:47:07 ok, it was the device tree. It seems the dtc compiler on my system was buggy.. Mar 31 23:47:17 xa0z: how big is your BBB supply? Mar 31 23:48:09 BBW, not BBB. And it's a 5v 2.1A cell phone charger Mar 31 23:50:10 xa0z: that's bigger than I would have guessed (for dying with wifi) Mar 31 23:50:40 According to the RPi wiki, this same wireless card requires a powered hub on their hardware too. Mar 31 23:53:25 does it say somewhere that the BBW+that wifi doesn't need a powered hub? Mar 31 23:55:36 I can't find anything anywhere about it. iandow (in here) told me he had similar issues with the same adapter on his BBW, but on his BBB it works fine. Apr 01 00:46:02 xa0z: I haven't tried the TL-WN722N on BBB, rather I use the DWA-121 - which works on the out-of-the-box Angstrom config, except I have to kill the wpa-supplicant process - can't be perfect can it. Apr 01 00:46:53 Oh, you made it sound like you used the WN722N on BBB and it worked fine. Apr 01 00:49:17 I wouldn't be suprised if it worked. I tried three different ones on the BBW, none worked. BBB seems to have a lot better support for wlan devies Apr 01 00:56:13 Adding in a powered USB hub worked pretty well. Apr 01 02:22:54 It's the kernel that lost support for a lot of the wireless drivers Apr 01 02:23:38 They removed one of the macros the drivers used Apr 01 02:24:48 Contact the company for the beta drivers Apr 01 02:45:52 The BBB advertises a "AM335x 1GHz ARMĀ® Cortex-A8" but since the A5A Revision the BBB has shipped with a AM3359 which appears to run at 800Mhz max... Am I mistaken? Apr 01 02:50:56 Hi guys, quick question, I am new here and to the beaglebone black Apr 01 02:51:19 I updated angstrom and formated a 16gb SD card for extra storage Apr 01 02:51:55 but when I insert SD card and boot the Beaglebone the indicator lights are all lit and steady and no boot happpens Apr 01 02:52:28 did I muff the formating of the SD card or do I need to insert the SD card after boot? Apr 01 02:52:44 when I insert the SD card after boot it shows up as extra storage Apr 01 02:53:42 me! lookin around **** ENDING LOGGING AT Tue Apr 01 02:59:59 2014
