**** BEGIN LOGGING AT Sun Mar 08 02:59:58 2015 Mar 08 03:03:57 i bought a used bbb and i cant get it to connect to linux or windows , i done dmesg in linux terminal and i see the am335x by texas instruments but i have yet to get it to connect someone help please Mar 08 03:10:06 benjie_: did you make an sdcard or are you trying just the eMMC? Mar 08 03:10:35 easiest way to "fix" emmc is with an sdcard... Mar 08 03:11:21 also, you may need to actually configure usb0 on linux Mar 08 03:11:46 *so that you can see the web interface, etc Mar 08 03:11:58 ive done both and how do you configure usb0 Mar 08 03:13:04 this might help => http://www.vctlabs.com/posts/2014/Sep/14/beaglebone_images/ Mar 08 03:13:22 usbnet stuff towards the bottom... Mar 08 03:17:36 nerboy: i tried route add default and it comes back network is unreachable Mar 08 03:46:39 did you do the full route command? Mar 08 03:47:14 if you're bringing everything up manually then you probably need more parameters Mar 08 03:47:31 eg, route add -net 192.168.7.0 netmask 255.255.255.0 usb0 Mar 08 03:50:40 yes , on the bbb the second led from ethernet is barely blinking and the last one from ethernet is flashing and power light is on. Mar 08 03:53:51 here is part of what i get that mentions bbb when i do dmesg.=0 [ 4655.321127] usb 1-1: Product: AM335x USB [ 4655.321134] usb 1-1: Manufacturer: Texas Instruments [ 4655.396698] rndis_host 1-1:1.0 usb0: register 'rndis_host' at usb-0000:00:1d.0-1, RNDIS device, 9a:1f:85:1c:3d:0e [ 4936.356167] usb 1-1: USB disconnect, device number 7 [ 4936.358166] rndis_host 1-1:1.0 usb0: unregister 'rndis_host' usb-0000:00:1d.0-1, RNDIS Mar 08 03:59:42 the disconnect is when you unpluh it right? Mar 08 03:59:53 *unplug even Mar 08 04:00:31 i might try the angstrom flash then, at least i know that works Mar 08 04:02:13 no i kept it plugged in the whole time Mar 08 04:06:44 the emmc flash correct Mar 08 04:08:50 did you actually flash it yourself? Mar 08 04:18:01 the guy i bought it from sold it to me cheap and he said it needed reflashed he had run into a problem instaling ubuntu.im sitting up my sd card to put angstrom image on there Mar 08 04:20:27 https://bpaste.net/show/1af85409e050 Mar 08 04:20:47 that's a rev A6A after booting off USB power Mar 08 04:25:39 benjie_: first time i checked latest debian, but it does have webserver that shows your board as connected Mar 08 04:32:44 im putting angstrom on sd card now . then im gonna power bbb with external power supply . then hold down s2 while i apply power and hold till it starts flashing correct Mar 08 04:36:35 that's "latest debian flas image" Mar 08 04:36:43 +h Mar 08 04:46:32 ive been holding the s2 button and added power and no lights have come on yet Mar 08 04:48:38 the flash card should just boot, flash, and shutdown Mar 08 04:49:40 bang BOARD Mar 08 04:50:21 so just put card in and plug power supply in and let it do its thing Mar 08 07:42:37 hello Mar 08 07:43:28 I'm trying to compile a boot image for bbb. Unfortunatley I'm not very familiar with Linux. Mar 08 07:44:45 RobertCNelson seems to use an SDK directory in his script: /dev/sdX Mar 08 07:45:08 which sdk package should I use? Mar 08 07:46:52 since the script complained about missing lsblk first thing I made was installing util-linux package. But now I'm, stuck. Mar 08 08:05:09 I'm currently downloading ti-sdk-am335x-evm-08.00.00.00-Linux-x86. But I'm only guessing. Mar 08 08:05:22 Chilli_: what are you really trying to do? Mar 08 08:06:24 This http://elinux.org/BeagleBoardDebian#Debian_Stable_.28wheezy.29 Mar 08 08:07:02 What I'm really trying to do is to make a boot image for bbb Mar 08 08:07:12 I thought that's what the article is about Mar 08 08:08:40 i am proposing an idea on Camera calibration using OpenCV in beagle bone -GSoC-2015 Mar 08 08:09:01 please discuss the possibilities Mar 08 08:14:47 Chilli_: you don't need to compile anything for creating a bootable image Mar 08 08:15:30 Chilli_: the /dev/sdX seems to have confused you. Do you have /any/ previous Linux or Unix experience? Mar 08 08:16:21 I have very little Linux experience. I'm confronted with Linux once every 5 years. I just installed debian in a virtualbox for now Mar 08 08:16:22 Chandy: there is a specific GSoC channel. Your missing is to find and join it yourself, without having to ask. Mar 08 08:17:23 whats the free node address of channel Mar 08 08:17:27 Chilli_: right, so you might want to learn some linux basics. Maybe get a book on that or look on the web for things. (not related directly to the BBB Mar 08 08:17:43 "* without having to ask.*" Mar 08 08:18:02 ok Mar 08 08:30:13 I felt that the SDX is the only puzzle peace missing to move on. But I might be wrong. Actually my target is not getting an Linux expert, but making a BBB app ;-). But it could be that one does not go w/o the other :(. Thx 4 ur time. Mar 08 08:31:46 sdx is the device name of your card reader Mar 08 08:31:54 but you have to understand some basics Mar 08 08:32:03 otherwise you'll keep running into problems Mar 08 08:32:48 it's like driving a car, you need to know that the key fits into the ignition and that you have to turn it Mar 08 08:33:29 and as I suspect you're on windows, there are windows instructions on beagleboard.org too Mar 08 08:39:43 @tbr thanks 4 the hint. Didn't stumble about that, yet. I will have a look. Don't get me wrong: I'm interrested in Linux. I'm just afraid to be distracted to much form my primary target when the dive get Mar 08 08:39:49 's to ddep ;-) Mar 08 08:40:09 is your card reader attached to the virtual machine? Mar 08 08:40:57 no. The card reader is on my wifes notebook ;-). Transferring images is my least problem. Mar 08 08:41:38 I could attach an external card reader to my PC. But I don't have donwloaded virtual box extensions for USB2 support, yet. Mar 08 08:44:16 I can still boot Debina from USB stick if virtualbox is a blocking point. For now I'm glad I can switch between OS w/o reboot. Mar 08 08:50:17 so what is the problem then? you just download a debian image, unpack it and write it to a µSD card Mar 08 09:05:24 ohh that's what u r talking about. I have successfully upgraded my BBB to the debian image from http://beagleboard.org/latest-images via windows. But I see there is the latest image available now OoO! So there is indeed not reason for me to struggle. I will just take the new latest image and everything should be fine. Mar 08 09:06:43 Thx for the unexpected solution. Mar 08 09:12:19 what the mranostay is OoO ? Mar 08 09:14:36 hahaha windows has problem accessing the card in the card reader. Nevertheless I wanted to have a look if the guest system can access it (linux is much more tolerant in these things). Guess where I searched for the SD card. /dev/SDx. I'm really getting old. Mar 08 09:16:24 yes, very old... devices.txt tells me that there was never /dev/SD* Mar 08 09:18:25 where can I seek help with ath9k wifi direct in the IRC? Mar 08 09:18:41 I try to run miracast from the bbb, and wifi p2p fails Mar 08 09:19:53 KotH: Eh? Mar 08 09:20:26 mranostay: i didnt want to use any more profane word Mar 08 09:21:10 cityoflights2: ath9k is so old that it should work out of the box on 99.98 of all systems Mar 08 09:21:13 Bite me you dirty Turk :) Mar 08 09:23:31 I mean ath9k_htc Mar 08 09:23:44 it should have p2p Mar 08 15:09:15 Hi, I am trying to understand the BBB boot process a little better. Mar 08 15:09:38 Upon power on, where does the reset vector execute out of? Mar 08 15:10:18 From the TRM for the AM335x chipset, I gathered that on reset it executes TI's ROM code out of a specific location in memory. Mar 08 15:11:26 Is the reset vector mapped to the ROM address permanently? Can we modify the boot ROM code? Mar 08 15:15:39 <_av500_> no Mar 08 15:15:42 <_av500_> you cannot Mar 08 15:15:47 <_av500_> thats the point about ROM Mar 08 15:16:21 <_av500_> when using in the non-xda developers sense Mar 08 15:16:30 <_av500_> used* Mar 08 15:44:52 You don't want to modify the boot ROM, that is the sure path of folly. Mar 08 15:58:48 I do not quite understand what's the pinout of uart port Mar 08 15:59:08 I want to connect uart cable to BBB J1 Mar 08 15:59:21 What should be the order of wires? Mar 08 15:59:50 do I need to connect +5vdc or rx, tx and gnd is enough? Mar 08 16:00:09 Necrosporus .. check the 'debug cable' section on elinux .. http://elinux.org/Beagleboard:BeagleBone_Black_Accessories#Serial_Debug_Cables Mar 08 16:34:43 Anybody have any idea why 'sudo poweroff' or 'sudo shutdown now' does nothing? Mar 08 16:34:54 I can only shutdown with the pushbutton next to the ethernet connector. Mar 08 16:54:17 I suggest checking the HW version and the SW version on your board then give that information as it may be just that version was updated but not the firmware on your board or it may be in the eratta for the HW Mar 08 16:56:46 "sudo halt" and "sudo shutdown -h now" are my favoured options Mar 08 16:57:18 GenTooMan: I'm looking into that now. Mar 08 16:58:04 although I got some strange things with RCN's debian and my allwinner board :/ Mar 08 16:58:05 veremit: Yeah, all of those do the same thing. They say the board is going down, but it never does. Mar 08 16:58:14 weird Mar 08 16:59:10 Yeah I'm running the latest Debian on the bbb and do updates regularly. Mar 08 16:59:31 hi guys i just downloaded the latest image for my beaglebone black, the ubuntu image with the 3.14 kernel, how are overlays handled now and is there a good guide on getting this setup to use overlays? Mar 08 17:17:07 GenTooMan: Is there an easy way to determine what the hardware version is? I know it has a 2G eMMC. Mar 08 17:18:25 I suppose that Makes it a rev B Mar 08 17:20:54 or prior Mar 08 17:21:30 should say on the board itself if you didnt remove the sticker with the serial Mar 08 17:24:02 I haven't removed any sticker and the only sticker is on P8 and has a barcode and A5Con it. Mar 08 17:25:15 revision a5 it is Mar 08 17:25:39 *A5C Mar 08 17:26:26 OK I have revision A5C and the latest debian in the eMMC. Mar 08 17:27:09 What is weird is that I jut put debian on an SC card and when I boot into that poweroff ans shutdown works fine. Mar 08 17:27:50 cnobile_, does it not work right when booting off the emmc? Mar 08 17:28:25 No I just get a message that says it's going down, but it never does. Mar 08 17:29:37 <_av500_> it wants to stay up Mar 08 17:30:08 Yeah, my BBB has a mind of its own I suppose. Mar 08 17:41:07 @av500 : Mar 08 17:41:14 #av500 Mar 08 17:42:03 <_av500_> just av500 Mar 08 17:42:12 <_av500_> or rather _av500_ Mar 08 17:43:26 @ av500 : Mar 08 17:43:33 <_av500_> yes? Mar 08 17:45:49 _av500_: I guess he left without saying a word. Mar 08 18:08:26 Hi Mar 08 18:09:40 I'm trying to make an sgx package for 3.19.1-bone4 according http://elinux.org/BeagleBoardDebian#SGX_BeagleBone.2FBeagleBone_Black Mar 08 18:10:49 I'm getting a certificate viloation Mar 08 18:18:04 It seems there is no way to add --no-check-certificate to sgx_create_package.sh - the problem seems to occure later. Does anybody know a worlaround? Mar 08 18:36:09 If stored the output of sgx_creat_package under http://www.mauterheim.at/Chilli/BBB/sgx_create_Package.sh__outpu.txt Mar 08 18:36:28 someone please give me toolchain link for cross compiling to beaglebone from intel x64 architecture ubuntu os machine Mar 08 19:09:00 thunder_kk .. try http://elinux.org/Building_BBB_Kernel Mar 08 19:09:54 or my personal choice .. Mar 08 19:09:55 !topic Mar 08 19:10:21 .. https://eewiki.net/display/linuxonarm/BeagleBone+Black Mar 08 20:03:13 @veremit thank you very much! you saved my day! can you also please instruct me to install device tree overlay in bbb? Mar 08 20:27:40 hi Mar 08 20:28:17 where is the cape-bone-lcd3-00A0.dts located in my BBB Mar 08 20:35:24 dts is in the kernel source Mar 08 20:35:55 blobs are normally in /boot somewhere Mar 08 21:05:56 cu Mar 08 21:06:42 hi ! my bbb shuts down with a terminal message "going to system halt" Mar 08 21:06:55 whats the problem with it ? Mar 08 21:13:38 and sometimes it says "Power button pressed" "the system is going for system halt now" Mar 08 21:13:45 ZeekHuge, you shuold expect "system halt" on shutdown :) Mar 08 21:13:56 if not, you got a problem! Mar 08 21:14:12 but its automatic. without pressing the button. Mar 08 21:14:27 hm .. you got a hardware problem .. Mar 08 21:14:34 check your button isn't sticking Mar 08 21:15:02 if you have a meter, you can check whether its "on" when its "off" Mar 08 21:16:13 no, it isnt. and this happens moslty when its display intensive work i.e. when i connect a display or when i connect BBB to VNC. Mar 08 21:16:46 hmm .. only other thing is your power supply is failling under load Mar 08 21:16:59 you running via USB or the barrel jack? Mar 08 21:17:10 barrel jack ... Mar 08 21:17:26 hmm and what size is your Power supply? Mar 08 21:17:49 5V 3Amps Mar 08 21:18:54 and a webcam is also connected to the BBB via externally powered usb hub. Mar 08 21:23:11 hmm .. well .. that's what I can think of to start with .. Mar 08 21:45:10 hi guys how i can downgrade my kernel to 3.8 as i cant seem to find much information on using overlays with the 3.14 kernel Mar 08 22:01:53 imanpakii: not what to tell you Mar 08 22:02:11 maybe google it and see which kernel source pops up Mar 08 22:06:21 hello. is there a recommended power supply for bbb? Mar 08 22:29:31 Yes Mar 09 00:03:41 How could I check if my uart cable is 3.3 v an not 5v? maybe multimeter against signal cable and gnd? Mar 09 00:17:06 yup, TxD is high when idle Mar 09 00:17:25 RxD no doubt also has a pull-up Mar 09 00:30:25 Necrosporus Tx idles high, so you can put a meter between Tx pin and GND to see what voltage its putting out Mar 09 00:31:12 similarly you can prove your pinout by measuring pins Tx/Rx and noticing their voltage (nb. RS232 is inverted voltage - ie. -12V is "high") Mar 09 00:31:57 veremit, I have tried to solder this cable to an arm device mainboard and it worked Mar 09 00:33:33 cool Mar 09 01:41:57 note that voltages in excess of max ratings may work too, but cause damage in long term :P Mar 09 02:00:07 You might have to replace the level shifters on the board if you drive them beyond 3.3V due to the internal protection diodes shunting to 3.3V or some such. Mar 09 02:00:45 what level shifters on board? :P Mar 09 02:01:41 hmm there is of course an isolation switch on the console port, depending on how it works it may actually protect against overvoltage Mar 09 02:02:30 if you put 5v into the am335x you're gonna end up with a molten blob of processor :) Mar 09 02:02:39 I swore their was a level shifter between the AM335X and the serial port. I thought the IO for the AM335X was 1.8V Mar 09 02:02:50 veremit: except the serial cable ain't a power supply Mar 09 02:03:01 veremit: it'll dip if you draw enough current Mar 09 02:03:19 GenTooMan .. there's a shifter between the rs232 port yes Mar 09 02:03:26 no Mar 09 02:03:32 I thought the rest of io was 3v3 .. Mar 09 02:03:38 maybe? Mar 09 02:03:43 or well, maybe they used a shifter for it, but it's then 3v3 to 3v3 :P Mar 09 02:03:54 zmatt . the rs232 is a driver chip actually :p Mar 09 02:04:01 there's no rs232 on it Mar 09 02:04:08 oh wrong board then lol Mar 09 02:04:14 my bad Mar 09 02:04:51 my experience of beagle-black serial ports was 3v3 io though .. Mar 09 02:04:56 GenTooMan: am335x can use 1.8V or 3.3V I/O (selectable per bank) Mar 09 02:05:05 GenTooMan: all of them are 3.3V on the beagle Mar 09 02:05:38 "bank" in this case is some non-obvious grouping of pins, wholly unrelated to GPIO banks or anything Mar 09 02:06:27 GenTooMan: check the "Supply" column of my pin-spreadsheet => https://docs.google.com/spreadsheets/d/1CK5c-Cs8G1RtzGo-J3VJsD9m5K-fp06AncgeYWsdjSU/view Mar 09 02:06:35 oh 6 banks sorry Mar 09 02:07:42 they're mostly to allow sd/mmc and ethernet to optionally operate at different voltage than the rest of the ios Mar 09 02:10:32 zmatt U15 isolates the UART pins from the processor. Mar 09 02:10:35 oh hey, the chip they used on the beagle for power isolation is actually fine with 5V Mar 09 02:11:06 Except they powered it with 3.3V Mar 09 02:11:17 GenTooMan: yes that's what I said, hmm there is of course an isolation switch on the console port, depending on how it works it may actually protect against overvoltage Mar 09 02:11:38 if I'm reading its datasheet right, it does Mar 09 02:12:04 I was probably reading the schematic whilst you were saying that. Mar 09 02:12:33 Sadly their are 2 U15s on the schematic on being on the processor :( Mar 09 02:13:15 I'm mostly pissed off they didn't connect RTS/CTS ... they're not even used for a different purpose, just left not-connected on both cpu and header Mar 09 02:13:28 fun when pasting a long line of text Mar 09 02:14:49 They use ORCad for this? Mar 09 02:14:55 * zmatt has no idea Mar 09 02:15:31 I see only one U15 Mar 09 02:15:44 PIN number U15 you don't see? Mar 09 02:15:56 sure, but that's a pin number Mar 09 02:16:08 When you are searching a PDF ... Mar 09 02:16:55 It's hard as heck to see the highlight.. I couldn't find J7 because it kept finding the processor pin (apparently connected several places) Mar 09 02:16:55 try searching for pin 1 of anything :P Mar 09 02:17:03 LOL Mar 09 02:17:19 Well it would be A1 for this IC ;) Mar 09 02:17:40 J1 will be even worse than J7 Mar 09 02:18:01 they really should have used a leading digit for the cpu balls Mar 09 02:18:09 (e.g. J01) Mar 09 02:18:38 OR do U5_J1 or somesuch Mar 09 02:19:21 intermixing pin numbers with other reference designators ... well these IC's are quite the pain Mar 09 02:20:20 so all this bla about making sure you get the 3.3V cable... when in fact U15 ensures a 5V cable would safely work too ... (though, to anyone reading this: better triple-check if I'm right about that before risking a board) Mar 09 02:22:24 though, when working with modern SoCs, it's better to develop an intuitive http://goo.gl/bRU8DV feeling w.r.t. 5V Mar 09 02:23:08 (funny enough it does have 5V tolerant pins.... two of 'em to be exact) Mar 09 02:27:48 The max input is VCC+0.5V so 3.8V is the max Mar 09 02:29:12 ehh, are you sure you're looking at the right datasheet ? mine says 0 to 5.5V in the recommended operating conditions Mar 09 02:30:02 (-0.5V to 6.5V in max ratings) Mar 09 02:30:38 zmatt .. for Vcc or Vio on io pin?¬ Mar 09 02:30:52 veremit: VI, input voltage Mar 09 02:30:56 mk Mar 09 02:31:10 think about it, if the inputs were limited to Vcc+0.5V then it would be useless as isolation Mar 09 02:31:15 since Vcc will be zero when the board is off Mar 09 02:31:24 SN74LVC2G241 Mar 09 02:31:33 its not true isolation is it? Its just level conversion Mar 09 02:31:39 it would have to be opto or something Mar 09 02:31:46 (since I use opto all the time for usb/etc IO) Mar 09 02:32:14 veremit: it's isolation in the sense of making sure no voltage is applied to am335x I/Os when not powered Mar 09 02:32:15 then you got >1 Vcc/Vss/etc Mar 09 02:32:30 zmatt .. well that is probably safe .. since that also blows up the processor :) Mar 09 02:32:45 i.e. it allows you leave your console cable connected when the board is off Mar 09 02:32:55 indeed .. and a wise design choice :) Mar 09 02:32:55 without U15 that would be damaging Mar 09 02:34:26 the fact that it'll also work as a unidirectional level shifter seems to be just a side-effect Mar 09 02:34:44 (its output will still be 3.3V, but I think a 5V serial cable will accept that too) Mar 09 02:39:33 veremit, the wires are +3.3 and +3.2V Mar 09 02:39:46 I'm talking about rx and tx to gnd Mar 09 02:40:01 So the cable should work with bbb Mar 09 02:40:12 Necrosporus .. I would say so Mar 09 02:40:30 It was not uart cable, but an old phone cable Mar 09 02:41:06 There are also other wires I didn't identify Mar 09 02:41:14 Maybe them are useful too? Mar 09 02:41:44 I have identified gnd, +5v, Rx and Tx, but there are three other wires in the cable Mar 09 02:44:24 rts/cts I would imagine are two Mar 09 02:46:00 they would have been useful... except they're left not-connected on the beaglebone -.- Mar 09 02:53:21 It would have required them to have 2 more isolation pins that might have been why. Mar 09 02:54:19 make Mar 09 02:54:25 doh! Mar 09 02:58:13 zmatt .. although it may be desireable to have flow control .. I've never seen an arm board with it actually used .. I dunno whether even uboot supports it, for example. Mar 09 02:58:13 But there are six pins in connector Mar 09 02:58:25 Why only 1, 4 and 5 are used? Mar 09 02:59:05 Necrosporus .. probably other purposes Mar 09 02:59:08 And why are not they 1 2 3? **** ENDING LOGGING AT Mon Mar 09 02:59:58 2015
