**** BEGIN LOGGING AT Sun Jan 12 02:59:59 2014 Jan 12 03:00:03 I can connect to my server @ work usin an SSH app on my blackberry :P~ Jan 12 03:00:53 As I in 192.168.7.2 Jan 12 03:01:07 thats only default for USB afaik Jan 12 03:01:23 it'll DHCP if it can on ethernet Jan 12 03:01:57 Right that is what I thought, I have tried root@beaglebone.local but that does not work Jan 12 03:02:19 hence you need to find its IP from another source .. eg. router devices page/dhcp leases/etc Jan 12 03:02:29 if you don't have a screen connected Jan 12 03:02:40 it's not able to give itself a DNS entry .. Jan 12 03:02:57 thats why the internet has associated servers of its own :) Jan 12 03:03:28 Ok so what do I do to get it to work Jan 12 03:04:19 well.. that depends what you have available to you .. and your level of expertise :) Jan 12 03:05:17 I have a PC running windows px experience is relative, so in this community I will say limited Jan 12 03:05:25 one of the simpler options is to get a USB cable and connect it to a computer .. sort out any drivers .. and connect to the IP you describe Jan 12 03:06:09 you can then do an "ipconfig" to see what IP address it comes up as .. and connect from wherever from there. Jan 12 03:06:45 if you have access to the router it connects to (assuming you have a cable router/etc) you should be able to figure out which device it is under the "attached devices" or "dhcp leases" part of he status pages. Jan 12 03:07:53 Ok will it also work if the BBB is connected via Ethernet and I execute the ipconfig from putty Jan 12 03:07:55 or you can connect a screen, usb hub, kb and mouse and go from there .. Jan 12 03:08:16 you will still need the beagle's IP to connect with Putty .. Jan 12 03:08:38 the shortcut of using USB is it gives you a Known IP of the device .. or else it could be Anything. Jan 12 03:08:53 (limited ot 255 entries for a Class B(?) subnet) Jan 12 03:08:58 It will connect with root@beaglebone.local Jan 12 03:09:07 I severely doubt it Jan 12 03:09:12 who knows what beaglebone is? Jan 12 03:09:25 what is tellin gyou that?! Jan 12 03:09:56 if every computer connected to the internet was called 'mypc' how would we tell them apart?? Jan 12 03:10:38 Well I have a reference book getting started with beaglebone and it works, have been able to flas LEDs and read switches ... Jan 12 03:11:04 hmmm... first I ever heard of that lol but .. ok. Jan 12 03:11:28 You are right if I had more than one BBB on my wifi Jan 12 03:12:15 I am booting up PC now and will see what I get with ip configuration Jan 12 03:14:00 Says command not found is there a particular directory. I need to be in I am in root Jan 12 03:14:22 "ifconfig -a" Jan 12 03:15:02 should give you a couple of blobs of info Jan 12 03:16:46 It does one the Internet address of 192.168.0.16 another a Bcast 192.168.0.255 I assume I use the Internet address Jan 12 03:17:17 veremit: beaglebone.local works if you have bonjour / avahi /zeroconf on your system and are on the same local network Jan 12 03:18:36 for assuming your beaglebone OS has avahi active, which is does by default on angstomr Jan 12 03:19:46 Makes sense I am using angstrum Jan 12 03:22:15 i guess you are using windows, which doesn’t normally have zeroconf. i think if you have itunes installed it will. but anyway “zeroconf” is the thing you need to use beaglebone.local, so serch for taht if you want to go that route Jan 12 03:23:17 Getting closer it now finds the BBB but I do not have a password set up on it and cannot just bypass it as I can with putty, so will probably have to set one up Jan 12 03:24:58 ah Jan 12 03:25:02 its not root/root .. ? Jan 12 03:25:20 I can't remember for stock angstrom .. Jan 12 03:27:21 hmm some say no root password and some 'root. Jan 12 05:15:51 hi Jan 12 05:16:08 hi Jan 12 05:16:23 where can i find beginner python programming instruction for bbb Jan 12 05:16:28 beagle bone black Jan 12 05:17:13 oh Jan 12 05:17:18 adafruit is a good place to start Jan 12 05:17:42 http://learn.adafruit.com/setting-up-io-python-library-on-beaglebone-black/overview Jan 12 05:19:50 ok I will check it out Jan 12 05:20:15 can python be used in ubuntu or linux platform too Jan 12 05:20:22 yeah Jan 12 05:20:28 or windows, osx, etc Jan 12 05:21:49 oh ok, can you recommend any book or site for python program in general Jan 12 05:24:58 maybe here: https://wiki.python.org/moin/BeginnersGuide Jan 12 05:25:37 but that adafruit guide has examples and is a good place to start without looking at other resoureces Jan 12 05:30:30 hi Jan 12 05:30:46 ive been trying to find a good lcd screen to use with beaglebone black Jan 12 05:31:20 but i cant figure out if a 1280x800 monitor will work even though only 1280x720 is supported Jan 12 05:32:56 ok got it thankyou johnwalkr Jan 12 05:51:42 no prob Jan 12 06:08:46 heya every body! Jan 12 06:08:49 Is Koen Kooi here? Jan 12 06:09:23 I'm having a hell of a time debugging failed interrupts on my BBB in Linux 3.8.13-00729-g8a94e04 Jan 12 06:09:45 I'm not seeing ECAP interrupts come down the line, despite seeing the status flags set in the relevant registers Jan 12 06:10:19 does anyone here have strong kernel-fu? :) Jan 12 09:24:21 what the hell ... angstrom does not know emacs o_O Jan 12 09:30:45 hmm no that is not that ... opkg search does not give me the list, why? Jan 12 09:44:07 bah ... #opkg install emacs24 emacs23 emacs23-nox emacs24-nox -> Unknown package -_-' Jan 12 09:48:37 "ed is the standard text editor" Jan 12 09:48:58 ;) Jan 12 09:50:05 ok ... but angstrom team could have build it's package Jan 12 09:50:19 and the opkg search does not give me any list Jan 12 09:51:04 opkg search ed does not give me any response Jan 12 09:51:18 bbb:~$ ed Jan 12 09:51:18 -sh: ed: command not found Jan 12 09:51:38 I wasn't being serious... "ed is the standard text editor" is a famous reply in vi-versus-emacs religious wars Jan 12 09:52:05 bbb:/home/bot# opkg install ed Jan 12 09:52:07 Unknown package 'ed'. Jan 12 09:52:08 (it's an ancient text editor) Jan 12 09:52:34 if all else fails: butterflies ;) Jan 12 09:52:41 bbb:/home/bot# ping gnu.org Jan 12 09:52:41 PING gnu.org (208.118.235.148) 56(84) bytes of data. Jan 12 09:52:57 aurelien: http://www.feep.net/~roth/geek-humor/unix/ed-is-standard-editor Jan 12 09:54:40 \_/°< o o o O Jan 12 09:58:12 it's sad there's no ed available though Jan 12 09:59:53 do no worry it's on debian ... well it's stay strange that it does not list any stuff ... apt-cache search ed list me lot and lot of things where opkg search ed just give me nothing Jan 12 10:00:33 same on your side? Jan 12 10:01:40 dunno, would have to grab my bbb and boot it up, but I also have some version of ångström on it so probably the same Jan 12 10:03:24 you can compile ed yourself of course, the source tgz is only 85K (and that despite being GNU Ed)... doesn't have any dependencies ;) Jan 12 10:03:45 * aurelien shutdown his BBB and will stand to receive some books and eletronical stuff -_- Jan 12 10:03:57 (interesting that the latest release is dated june 2013... people are still maintaining ed... :D ) Jan 12 10:04:42 then after, that will help me to make the choice of the distro for my use and then build the packages if necessary Jan 12 10:05:15 I have virtually no experience with linux on the bbb Jan 12 10:05:24 hmm .... Emacs let me TRAMP the remote machine ... so it's not a problem Jan 12 10:05:25 oh Jan 12 10:05:46 angstrom is a gnu / linux distro ... so you have some Ex! Jan 12 10:06:08 I'm still trying to figure out how to get the JTAG connector soldered onto my bbb so I can start having proper fun with it Jan 12 10:06:50 you sounds to have some electronical engineering background Jan 12 10:08:19 well actually my background is in mathematics, but I ended up working on firmware mostly Jan 12 10:09:24 ah ah! that should be great that you'll make retro engenerring to free some hardware and make them usuable on the linux-libre kernel version! Jan 12 10:09:56 TI chips are actually pretty decently documented Jan 12 10:09:57 which mean by the usuable on all Operating System by the way :-) Jan 12 10:10:09 yep but non-free Jan 12 10:10:37 not sure what you mean by that, I'm referring to publicly available docs (I haven't signed any NDA with TI) Jan 12 10:10:52 free as in freedom Jan 12 10:11:49 I mean that if you get some hardware which are non-free (because of the license) they don't works (not recognize) by linux-libre kernel and some by linux to. Jan 12 10:12:09 retro engenering offer sometime the way to blob the kernel to make it works Jan 12 10:12:12 the main part that isn't publicly documented is the 3d graphics accelerator Jan 12 10:12:28 yep ... often but not only Jan 12 10:12:56 http://www.h-node.org list A / B / C type of compatibility of hardware Jan 12 10:13:14 h-node is recognized by the free software foundation Jan 12 10:15:58 reverse engineering is a lot of work though, I'd say just vote with your money and prefer hardware by manufacturers who actually document their chips... TI seems to be an order of magnitude better than many other companies in that regard, so that's a good reason to get a BBB rather than e.g. a raspberry pi Jan 12 10:16:40 exact, that is why i have choose BBB :-) Jan 12 10:19:18 time to Cook! See ya! Jan 12 10:19:38 see ya Jan 12 12:13:40 ulli: maybe http://www.jerome-bernard.com/blog/2012/06/04/beaglebone-serial-ports-and-xbees/ could help you there is interesting part on configure UARTs and other informations. Jan 12 12:24:25 good morning everyone Jan 12 12:26:04 mooo Jan 12 12:42:05 aurelien: thanks I understand what I have to do but I have debian installed and the path /sys/kernel/debug/omap_mux/ is not available.... Jan 12 12:53:49 ulli, on debian wheezy / BB https://groups.google.com/forum/?fromgroups#!searchin/beagleboard/omap_mux$20debian/beagleboard/VWss3WO2dKA/nm0_Gb1h8UQJ Jan 12 13:21:33 aurelien: looks like I have to use the /sys/class/gpio interface because I do not have the "/sys/kernel/debug/omap_mux/" directory. The device is mounted but no folder like omax_mux available... Jan 12 13:26:15 ulli, afaik, i do not have omap_mux on BBB with it's original angstrom OS Jan 12 13:27:03 bbb:/home/bot# find / -path omap_mux Jan 12 13:27:04 bbb:/home/bot# find / -name omap_mux Jan 12 13:27:04 bbb:/home/bot# Jan 12 13:31:04 aurelien: I executed it as root. nothing found. Jan 12 13:31:41 so it's not coming from the GNU but it seems to be a kernel issue ... maybe someone using FreeBSD could confirm/infirm ... or the UART on/off works by another way. Jan 12 13:32:15 I activated UART over uEnv.txt Jan 12 13:32:36 oh this files once again Jan 12 13:37:03 aurelien: hmm.. Jan 12 14:52:11 hi guys,.. can anyone help me with my touch vontroller ADS7846 ? Jan 12 16:56:49 Hello. I am new to beagle boards. What is the difference between BeagleBoneBlack and BeagleBoard-xM? Jan 12 16:57:18 I am looking for such boards with two or three ethernet ports Jan 12 16:58:23 i don't think you will find one with multiple ethernet Jan 12 17:00:15 thank you jacekowski .. do you have maybe another recommendation? The following boards are interesting but they also don't have multiply ethernet interfaces :( Jan 12 17:00:19 http://hardkernel.com/main/products/prdt_info.php?g_code=G138745696275 Jan 12 17:00:19 http://hardkernel.com/main/products/prdt_info.php?g_code=G137510300620 Jan 12 17:00:23 if you want a router, buy a router. tp-link will sell you one for $30 Jan 12 17:00:49 W1N9Zr0, I want a router with OpenBIOS / WRT Jan 12 17:01:06 lots of tp-link routers are compatible with openwrt Jan 12 17:01:07 not this commercial crap with NSA backdors Jan 12 17:01:35 ironm: http://www.pcengines.ch/ Jan 12 17:02:06 Rickta59, yes .. thank you. I know this hardware. It is quite old one Jan 12 17:02:41 yeah i have one that is probably 15 years old at this point Jan 12 17:03:31 Exynos Samsung boards require only 3 to 5 watts .. I guess Alix boards much more, right ? Jan 12 17:03:34 back when I thought a 64MB compact flash card was huge ; ) Jan 12 17:04:56 Rickta59, well .. my first (self designed) 6502 system had 16KB static RAM . it was a lot 30 years ago ;) Jan 12 17:05:24 what are you going to do with this board? Jan 12 17:09:57 Rickta59, the Exynos one? Jan 12 17:10:05 Hi. In the Angstrom Distribution link, there are two BBB-eMMC-flasher-xxxxxx files. Which one should I use? Jan 12 17:10:47 One is BBB-eMMC-flasher-v2013.06-2013.11.20.img.xz and the other one is BBB-eMMC-flasher-2013.09.12.img.xz Jan 12 17:11:02 one of my targets are to sue some "open hardware / BIOS) hardware as routers Jan 12 17:11:11 s/sue/use/ Jan 12 17:14:03 what about this Development Kit? .. AM3359 Industrial Communications Engine - http://www.ti.com/tool/tmdsice3359#0 Jan 12 17:14:56 the price is less important Jan 12 17:16:50 Hi there, I'm new to BeagleBone Black Jan 12 17:17:30 have you got it already CubeMan3 ? Jan 12 17:17:51 Yes I have, it's pretty cool. Jan 12 17:17:55 maybe I will buy such one Jan 12 17:18:00 I'm just having some trouble getting started Jan 12 17:18:13 CubeMan3: welcome on board! Jan 12 17:18:28 ironm: you will use it as a cap with BBB?? Jan 12 17:19:07 I have a 8GB microSD card and after loading it with the latest image (used Win32 Disk Imager), I think it auto-partitioned my card Jan 12 17:19:14 CubeMan3, what was your main purpose to buy this BeagleBone Black Board ? Jan 12 17:19:32 To learn embedded systems Jan 12 17:19:49 aurelien, I can't follow what you exactly mean *sorry* ... "aurelien> ironm: you will use it as a cap with BBB??" Jan 12 17:20:37 ironm: you speak of http://www.ti.com/tool/tmdsice3359#buy ... so i was trying to understand what you want to do with that? Jan 12 17:21:27 But after loading the image, I think my microSD card was auto-partitioned and the other part of the drive disappeared Jan 12 17:21:45 aurelien, yes .. It is like beagle boards .. with two ethernet interfaces Jan 12 17:22:08 Now it only says there's 70MB available... on an 8GB card Jan 12 17:22:18 and much more ... seems to have also a battery on board Jan 12 17:23:10 CubeMan3, for such experiments I would always use clean microSD .. in case you loose data Jan 12 17:23:27 It was a brand new SD card Jan 12 17:23:52 ironm: a battery ... do you think it can need the use of a fan like the cubieboard2? Jan 12 17:24:28 aurelien, I don't know Jan 12 17:24:43 probably Jan 12 17:26:39 aurelien, it is not quite cheap .. $179.00 Jan 12 17:27:09 ironm: yep, maybe cheap for that sort of functionnality Jan 12 17:27:33 yes . I think so Jan 12 17:29:40 It would be really nice to have a beagle board with at least two ethernet interfaces (better three) .. hopefully GBe NICs Jan 12 17:30:03 maybe a cape could do that :-) Jan 12 17:30:47 I don't know cape yet :( Jan 12 17:31:17 http://elinux.org/Beagleboard:BeagleBone_Capes Jan 12 17:31:29 thanks :) Jan 12 17:31:49 in fact the BBB need a proto cape kit compatible Jan 12 17:32:57 ah ah there is one! http://elinux.org/Beagleboard:BeagleBone_Proto_Cape ironm on that one you could be able to build your own! Jan 12 17:33:52 there a lot of add ons :) Jan 12 17:35:11 Hi. In the Angstrom Distribution link, there are two BBB-eMMC-flasher-xxxxxx files. Which one should I use? Jan 12 17:35:22 ironm: that is the capes, but you can build your own or add some more from the electronical market directly Jan 12 17:36:21 Guest94745: try first uname -a in a terminal to know if you have not already the last one installed Jan 12 17:37:34 aurelien, I wonder that there are no such 2 x 1GBe caps yes Jan 12 17:38:35 in case it is possible to design such one with the available "bus" (connectors on the BBB) Jan 12 17:39:03 ironm: some capes are on project, like the sensorcape and much more ... http://www.michaelhleonard.com/projects/sensorcape/ http://beagleboard.org/project Jan 12 17:39:51 ironm: who knows, maybe you will launch your own on http://www.kickstarter.com/ :-) Jan 12 17:40:26 :) Jan 12 17:41:17 first of all I will save our conversation here .. (a lot of very interesting details from you) Jan 12 18:09:17 aurelien, it is rather not possible to implement a multiply ethernet add on using these two extension header connectors of BBB (according to schematics) Jan 12 18:15:23 ironm: and one on a proto cape + one of the BBB could not make the trick? Jan 12 18:15:28 another question: is BIOS (firmware) of BBB open source ? Jan 12 18:15:52 aurelien, no .. it is not possible Jan 12 18:16:09 in easy way Jan 12 18:16:16 only over USB Jan 12 18:16:23 or like that Jan 12 18:16:58 the CPU should have two ethernet blocks (silicon) Jan 12 18:17:15 oh ok ok Jan 12 18:17:19 depends what CPU you put on the board Jan 12 18:18:11 and a proto cape with the right cpu and one eth? Jan 12 18:19:16 aurelien: the BBB doesn't have a "BIOS" and all boot-loaders that you put on SD or eMMC are open source Jan 12 18:19:41 err ironm that is, sorry aurelien Jan 12 18:19:41 ^ ironm Jan 12 18:20:01 tbr, np, i am also interested :-p Jan 12 18:20:55 MLO is just a cut-down u-boot, then u-boot and then you already have the linux kernel Jan 12 18:23:15 hi guys Jan 12 18:32:28 hi Jan 12 18:32:38 can you help me? Jan 12 18:33:21 maybe Jan 12 18:33:42 yes I can help you! Jan 12 18:34:11 * eintopf open a bottle of beer Jan 12 18:34:20 udani: IRC principle is to come and ask :-) Jan 12 18:35:04 i connect a powersupply to my beaglebone and the usb cable Jan 12 18:35:29 and few seconds turned off Jan 12 18:35:38 and now i cant turn on Jan 12 18:35:54 which type of powersupply? Jan 12 18:36:23 5v switching power supply Jan 12 18:36:39 have you tried to boot with just the usb? Jan 12 18:36:47 with just the powersupply? Jan 12 18:37:11 i tried at the momment but nothing Jan 12 18:37:39 udani: disconnect all, reconnect usb, nothing happen? Jan 12 18:38:01 tbr: there is first stage bootloader burned into rom Jan 12 18:38:15 yes nothinh Jan 12 18:38:20 *nothing Jan 12 18:38:29 udani: how do you connect the powersupply? Jan 12 18:39:03 with a simple cable Jan 12 18:39:03 USB + powersupply could have burn the BBB?? Jan 12 18:39:52 i dont know but i think this happend Jan 12 18:40:19 hmm sounds strange ... your BBB have been hurt by something? Jan 12 18:40:32 no Jan 12 18:41:05 * aurelien have no idea ... and give his tong to the cat Jan 12 18:41:13 jacekowski: read my answer very carefully, again. Jan 12 18:41:52 i read your anwser but the power led doesnt work Jan 12 18:42:02 tbr: you forgot to mention binary only ROM that is loaded before MLO Jan 12 18:42:36 jacekowski: I know about ROMBL, but it does NOT live on SD/eMMC, does it? and that's what I explicitly referred to. Jan 12 18:43:10 yes, but that's not what he asked about Jan 12 18:43:37 also all ROMBL really does is load a boot loader from SD/eMMC/UART/... Jan 12 18:43:43 can i check manually the power supply on board? Jan 12 18:44:10 tbr: at least, that's what you believe it does Jan 12 18:46:06 jacekowski: sigh, you're hell-bent on digging into this topic, aren't you? I am aware of the /other/ things, but most of that is inside the chip or under a pile of NDAs anyway and mostly irrelevant to booting the system, also it's a bloody mask ROM. Jan 12 18:46:26 or if not a mask rom, then a PROM Jan 12 18:46:46 it can have pile of backdoors ther Jan 12 18:46:47 there Jan 12 18:46:57 anything can have a backdoor Jan 12 18:47:14 if you don't trust the chip, then you need to get your own sand, and design your own Jan 12 18:48:03 I still find the situation much preferable to some 'magic' blob of binary that boots a GPU, that then boots an ARMv6 Jan 12 18:49:24 thank you tbr ... there is a kind of SYS/BIOS for this Texas CPU chip ... http://www.ti.com/general/docs/lit/getliterature.tsp?baseLiteratureNumber=spruex3&fileType=pdf Jan 12 18:50:33 what can i do with power button? Jan 12 18:50:43 I would expect something like that .. " tbr: there is first stage bootloader burned into rom" Jan 12 18:51:36 sysbios is not linux though, is it? Jan 12 18:51:49 exactly ... "jacekowski> it can have pile of backdoors ther" Jan 12 18:52:00 not tbr Jan 12 18:52:02 18:47:14< tbr> if you don't trust the chip, then you need to get your own sand, and design your own Jan 12 18:52:20 I don’t trust the sand. Jan 12 18:52:52 ion: ok, back to the cave you go. ;) Jan 12 18:53:02 every operating system (linux, adnroid, openbsd etc) is placed normally a kind of level above Jan 12 18:53:54 what can i do with power switch? Jan 12 18:58:45 tbr: But i don’t trust the cave either! Jan 12 19:00:58 -- ion got eaten by a grue -- Jan 12 19:03:24 ion, you should trust anyone .. just learn and audit every piece of source code that looks suspicious. It is hard job Jan 12 19:03:31 +not Jan 12 19:30:02 different than BeagleBone there is not JTAG interface on BBB. Any idea why ? Jan 12 19:32:43 ironm: wrong, http://www.elinux.org/Beagleboard:BeagleBoneBlack#Optional_JTAG Jan 12 19:32:55 http://elinux.org/Beagleboard:BeagleBoneBlack#Optional_JTAG Jan 12 19:33:01 hah Jan 12 19:33:31 thanks a lot tbr and myself .. I will check this link immediately Jan 12 19:50:03 ahmm ... "To install the JTAG header, all you have to do is install P2 on the back of the board." .. did someone installed this "P2 is a Samtec FTR-110-03-G-D-06 connector>" already on the BBB ? Jan 12 19:50:56 s/ed /e / Jan 12 19:53:51 ironm: JTAG is a not very often used feature on those boards. I believe some people did, but they might not even be here on IRC. Jan 12 19:54:24 this is probably also the reason why they removed the pricy usb-JTAG part from the BBB design Jan 12 19:55:05 what do you need JTAG for, out of curiosity? Jan 12 19:55:22 tbr, as far as I understand adding this connector is just a normal JTAG port .. without the USB stuff, right ? Jan 12 19:55:48 myself, I want to use this board as Development Board Jan 12 19:55:58 If you want to JTAG this board, you need to bring your own JTAG adapter, yes. Jan 12 19:56:13 ironm: correct Jan 12 19:56:36 yes .. it is anyway a good idea to have a separate emulator with JTAG Jan 12 19:56:52 ironm: most people who here claim they need JTAG - they really don't. hence my caution. Jan 12 19:56:54 thank you tbr and myself :) Jan 12 19:57:37 as most people run Linux and there the need for JTAG is quite rare Jan 12 19:57:50 tbr, my goal is like BBB board but with two ethernet interfaces on it (or three in case it is possible) Jan 12 19:57:54 for user space debugging, well, there are better tools Jan 12 19:58:06 ironm: get the AM35xx dev board, it has two Jan 12 19:58:11 tbr, e.g. .. what tools ? Jan 12 19:58:21 gdb, strace, etc. Jan 12 19:58:42 tbr, yes .. that is what I want .. to buy https://estore.ti.com/TMDSICE3359-AM3359-Industrial-Communications-Engine-ICE-P4684.aspx Jan 12 19:58:54 I don't need a hardware debugger to debug a user-space problem, 2-3 layers above the hw Jan 12 19:59:49 am335x, right Jan 12 19:59:52 well .. when you want to "play" with the "BIOS" (auditing) you will rather need JTAG Jan 12 20:00:47 as said, there is no BIOS, only ROMBL and that goes away once you are in MLO Jan 12 20:01:04 and there is probably no way to get to ROMBL with JTAG Jan 12 20:01:17 I guess there will be quite a lot of people interested in an BBB with two ethernet interfaces Jan 12 20:01:44 tbr, well .. I mean such ROMBL Jan 12 20:02:04 btw: you are aware of the excellent documentation from TI (TRM) and CCO (SRM) Jan 12 20:02:16 no idea .. it is possible .. (I hope it is) ... " and there is probably no way to get to ROMBL with JTAG" Jan 12 20:02:35 I didn't read this documentation yet Jan 12 20:02:52 then you should do that before anything else Jan 12 20:03:08 do you have a link maybe ? Jan 12 20:03:19 you're gonna have to read it all anyway, might as well do it now before asking more questoins that waste everyone's time Jan 12 20:03:30 true .. sorry myself Jan 12 20:03:52 I'd expect that beagleboard.org links to SRM and probably TRM Jan 12 20:04:06 it is difficult at the beginning to find the right entry Jan 12 20:04:23 thank you Jan 12 20:05:00 BBB makes a very good impression Jan 12 20:05:25 it builds on a lot of experience of designing open hardware Jan 12 20:05:39 BB classic, BBxm, BBW Jan 12 20:05:46 to an extent PandaBoard Jan 12 20:06:10 I wonder if there is a reason at all to think about BeagleBoard-xM Jan 12 20:06:44 in my case Jan 12 20:13:20 Hey! Who can I contact to be Beaglebone Distributor? Jan 12 20:13:37 *Beagleboard :)) Jan 12 20:14:29 semaf: circuitco Jan 12 20:16:20 Thanks tbr Jan 12 20:25:49 Hi, does anybody know how to disable "pinmux_i2c2_pins" on the BBB. It blocks Uart1! Jan 12 20:50:59 I guess there will be quite a lot of people interested in an BBB with two ethernet interfaces Jan 12 20:51:00 correct Jan 12 20:51:15 are there plans? Jan 12 20:51:38 I was thinking myself about such design Jan 12 20:51:58 did you have a specific purpose in mind? Jan 12 20:52:00 using BBB as base .. Jan 12 20:52:10 base? Jan 12 20:52:10 yes .. router Jan 12 20:52:16 sure, figures Jan 12 20:52:32 shame pyh is so fat Jan 12 20:52:35 phy * Jan 12 20:52:46 the BBB design as base for new design . with two ethernet interfaces on board Jan 12 20:53:24 compared to other connection interfaces Jan 12 20:53:27 I don't know how much effort it means Jan 12 20:53:39 what would you take away from the bbb to preserve the same size, but add PHY? Jan 12 20:53:45 depends what is possible Jan 12 20:54:07 well, just looking at it.. phy looks to be the single biggest component on the board Jan 12 20:54:10 a good question .. " what would you take away from the bbb to preserve the same size, but add PHY?" Jan 12 20:54:39 a router usually doesn't need graphic on board Jan 12 20:55:05 but then ironm, what do you need so many GPIO pins for if your primary use-case for dual ethernet is router? Jan 12 20:55:19 imho, better buy a usb2ethernet adapter Jan 12 20:55:28 than wait for bbb with dual eth Jan 12 20:55:46 well .. an industrie control board does need some GPIOs Jan 12 20:56:11 I don't want to wait .. I want do design myself Jan 12 20:56:18 in case it makes sense Jan 12 20:56:57 a new design shouldn't be only an ordinary router Jan 12 20:59:44 first idea would be to remove the graphic part and to add one ethernet interface more and one usb port Jan 12 21:04:23 awasj, I will buy http://www.ti.com/tool/tmdsice3359#0 .. TI's two ethernet interfaces "AM3359 Industrial Communications Engine" Jan 12 21:10:59 interesting Jan 12 21:12:51 wow, price! Jan 12 21:13:50 Hi there Jan 12 21:14:10 I'm new to BeagleBone Black and I'm having some trouble updating to the latest software Jan 12 21:14:55 I just downloaded and flashed the eMMC with the latest software version using a microSD card Jan 12 21:15:57 After the flashing was complete (all LEDs solid), I went on PuTTy and checked the software Jan 12 21:16:10 And it says that I'm still on the old version Jan 12 21:16:27 I used the command " cat /etc/version " Jan 12 21:16:50 Or is there another way to check the version? Jan 12 21:17:47 My hardware version is A5A Jan 12 21:18:51 Last chance before I fork out £40 on eBay; has anyone seen any UK or European BBB in stock? Thanks. Jan 12 21:18:58 CubeMan3, after Update I would restart the system Jan 12 21:19:36 smssms, I am going to order some BBBs in US Jan 12 21:19:59 ironm - who from? Jan 12 21:20:23 I am in Switzerland Jan 12 21:20:29 I did and it still says I'm on the old version Jan 12 21:22:14 smssms, I didn't decided for any particular US distributor yet Jan 12 21:22:35 Hi, does anybody know how to disable "pinmux_i2c2_pins" on the BBB. It blocks Uart1 RTS!!! Jan 12 21:22:39 CubeMan3, it looks like the upgrade didn't work Jan 12 21:22:59 ironm - I've heard others saying they could not find stock in the US either, but I've ot checked... Jan 12 21:28:04 smssms, it looks like all I have checked don't have BBB on stock yet Jan 12 21:28:28 ironm - thanks, why do you say yet, is something new coing? Jan 12 21:29:31 I don't know if they have had it before .. therefore my "yet" Jan 12 21:29:49 ok Jan 12 21:34:51 smssms, http://uk.farnell.com/jsp/shoppingCart/shoppingCart.jsp?_requestid=225704 Jan 12 21:35:02 32.88 Jan 12 21:35:17 will be available for delivery on 7 Feb, 2014 Jan 12 21:38:03 Good spot, but I am getting impatient and may have to go for the eBay bloke if no shops have it in stock now. Jan 12 21:45:07 http://uk.farnell.com/olimex/a13-olinuxino-micro/a13-cortex-a8-olinuxino-micro-sbc/dp/2308267 Jan 12 21:46:39 These are in stock..... Jan 12 22:50:26 how can i assign the P8 header pin modes on the beaglebone black? Jan 12 22:51:29 ie. i need the lcd_data signals on pins 31-46 on P8 and the manual states they need to be in mode0 for that Jan 12 23:57:12 hey everybody Jan 12 23:59:09 anybody know if there has been any progress on porting pi4j (or a similar tool) to the bbb? Jan 13 00:02:42 quetwo: have you seen http://project-bonsai.org/accessing-beaglebone-black-gpio-from-java-part-1-understanding-gpio/ ? Jan 13 00:03:15 still uses the sysfs though Jan 13 00:03:43 yup. Jan 13 00:03:59 it's a bit too slow for the project I'm trying to work on. Jan 13 00:04:43 i'm trying to collect serial data at 9600bps. haven't been able to get the gpio via sysfs calls to be accurate at anything over 1200bps Jan 13 00:05:09 ah I see Jan 13 00:05:18 I doubt the python bindings are any better .. Jan 13 00:05:28 nod Jan 13 00:06:34 i've seen some c/c++ apps use memcpy to the registers to get descent speeds. don't know if anybody has been working on something similar in java Jan 13 00:06:51 quetwo: somethign along the lines of http://stackoverflow.com/questions/13124271/driving-beaglebone-gpio-through-dev-mem ? Jan 13 00:06:52 is it possible to power the BBB trough both, +5V AND USB? Jan 13 00:07:14 ie. to power capes and be able to have usb comms Jan 13 00:07:16 ssl_: technically yes .. but the board is likely only to use one ... Jan 13 00:07:34 thats ok, thanks Jan 13 00:07:48 ssl_: the recommended method remains to use a capable 5V power supply though Jan 13 00:08:09 since technically USB can only support 500mA max. Jan 13 00:08:12 its just for testing Jan 13 00:08:39 ssl_: should work... but if it doesn't .. thats one possibility to be sure to rule out :) Jan 13 00:09:00 ok Jan 13 00:09:05 veremit: yup. that. Jan 13 00:09:30 quetwo: that get you started? :) Jan 13 00:10:10 seen it already. was just checking to see if you guys knew of anybody who already started such a project. Jan 13 00:10:26 so i don't spin my wheels if somebody else already has ;P Jan 13 00:10:28 if google doesn't know ... :) Jan 13 00:10:33 lol Jan 13 00:12:58 nod. sounds like a plan. going to start with pi4j and map all the registers over. hopefully that bit of trickery will work Jan 13 00:13:31 certainly plenty of results using Pi .. but then th ebeagle has been much slower to permeate than Pi .. Jan 13 00:14:00 it should be possible Jan 13 00:20:52 i have trouble to get my lcd working with my beaglebone black. i have attatched it via the lcd_data lines but i have only a black screen. xrandr over ssh tells me "cant open display" Jan 13 00:20:57 any ideas? Jan 13 00:22:13 is it detected .. uhm .. nvm that - it wont be 'detected' .. so you're gonna have to tell th ebeagle it exists. Jan 13 00:22:37 how to? Jan 13 00:22:45 if you're ssh'in and you want an X- session, you'll have to enable X forwarding .. both at the server end and your ssh client. Jan 13 00:23:47 i want to enable the lcd_data lines so the picture is outputted to the attatched lcd Jan 13 00:24:15 i tried with xrandr --output ... etc but is always tells me cant open display Jan 13 00:24:48 isnt x11 forwarding for displaying the screen over the ssh line? thats not what i want to achive Jan 13 00:25:31 the ssh connection will assume you want to process X command in your current shell Jan 13 00:26:01 if you want to edit the running X session you need to set the DISPLAY variable to :0.0 Jan 13 00:26:16 xrandr will only work on displays that it "knows" about or detects Jan 13 00:26:58 as you're physically connecting to pins on the beagle which have no "intelligence" eg. I2C .. you need to tell the beagle where your display is .. and what resolution/display timings you wish to use with it. Jan 13 00:26:59 thats the issue here. i need to force it to think i have a display attatched, because it cant detect it via the lcd_data lines Jan 13 00:27:08 precisely Jan 13 00:27:35 root@beaglebone:~# xrandr -display :0.0 --output HDMI-0 --mode 640x480 --rate 60 No protocol specified Can't open display :0.0 Jan 13 00:28:00 now .. on the LCD panel I use .. I force a resolution on the kernel command line with a video= line with the resolution/refresh/calculate timings and a Force Enable parameter Jan 13 00:29:59 what file to write that kernel command to? Jan 13 00:30:51 because you need to initialise the beagle's graphics driver Jan 13 00:30:52 else you HAVE no display Jan 13 00:31:25 and this is done via the kernel command? Jan 13 00:31:55 Before I was so Rudely interrupted .... the BBB also assumes that it can detect and set parameters based on the HDMI DDC interface Jan 13 00:32:12 * by default Jan 13 00:33:23 im sorry, didnt mean to interrupt you. Jan 13 00:33:39 * veremit blames the internet/ISP/freenode/etc lol Jan 13 00:33:44 not your fault :) Jan 13 00:33:48 oh ok :) Jan 13 00:35:00 now, since i dont use the hdmi interface, i need to force the kernel to think i have a display attatched by issuing the kernel argument video=... but where do i have to save it? Jan 13 00:35:16 i dont want to type the command every boot, you know? Jan 13 00:35:53 right .. I recommend editing your uEnv.txt file in your boot partition Jan 13 00:36:05 for me .. that /boot/uboot .. but that may not apply to Angstrom Jan 13 00:36:41 i see a uEnv.txt file in /boot/ Jan 13 00:37:11 only content is: optargs=run_hardware_tests quiet Jan 13 00:39:48 and i assume i have to add another line with optargs=video=HDMI-A-1:640x480@60 to this? Jan 13 00:40:02 ill just try it Jan 13 00:42:32 you need to add to the existing line Jan 13 00:42:37 or one with overwrite the other Jan 13 00:43:07 I recommend adding an 'e' after the @60 too .. thanks to rcn-ee for that one :) Jan 13 00:43:45 one will** override Jan 13 00:45:25 like this? optargs=video=HDMI-0:640x480@60e run_hardware_tests quiet Jan 13 00:45:34 whats the "e" for? Jan 13 00:45:40 e Forces the display ON Jan 13 00:45:51 ah cool Jan 13 00:45:53 else without a physical connection it assumes there is no display Jan 13 00:46:14 its a 'feature' of modern display selection mechanisms ;/ Jan 13 00:46:33 took me a long time to find that out .. with a much needed hint from somebody in here Jan 13 00:46:58 did you see the chalkboard 10" display?! :) Jan 13 00:47:07 thats what I'm working with. Jan 13 00:47:45 also .. did you find the lcd pins exposed? I might be able to save a customer some $$ if they do indeed appear on the beagl headers :/ Jan 13 00:47:57 im using and old spare Jan 13 00:48:06 soldered the ports myself Jan 13 00:48:08 aritey Jan 13 00:48:16 ook :) Jan 13 00:53:27 I am writing some pru code (just sort of feeling it out) and I have a loop with a qblt at the bottom that checks the value of a register and jumps back to the top of the loop Jan 13 00:53:58 that uEnv.txt thing dont seem to work, since my cat /proc/cmdline does not inclue the video parameter! Jan 13 00:54:13 the loop exits, but for some reason the register the qblt checks always seems to be 1, do you know if qblt alters register contents in anyway? Jan 13 00:54:17 ssl_ .. you probably got the wrong uEnv.txt then .. Yes .. there's more than one :p Jan 13 00:54:34 ok ill use "find" Jan 13 00:54:52 check whats mounted with 'mount' and 'fdisk -l' Jan 13 00:55:14 you should see .. more than the uEnv in the right folder Jan 13 00:55:29 I won't say kernel .. because some distro's embed it on the disk .. Jan 13 00:56:04 I really need to get a stock Angstrom going lol Jan 13 00:57:26 ok, found the right one: /media/BEAGLEBONE/uEnv.txt Jan 13 00:57:40 now it's on the cmdline, but still no display Jan 13 00:58:21 right .. you may find it helpful to put some extra debug on the drm module .. see whats happening Jan 13 00:58:46 from memory something like "drm.debug=0xFF" was max verbose I think Jan 13 00:59:17 kernel command line again Jan 13 00:59:31 then read the dmesg .. see what hints it gives Jan 13 01:00:07 think you may find an 'M' before your @ after your resolutino is critical Jan 13 01:04:46 The component labeled RT1 near the USB connector sits high above the expansion connectors P8 & P9 which I am guessing will restrict proper seating of a CAPE. Is this a problem? How can it be fixed without damaging the component? Jan 13 01:05:52 rocky1234.. it won't .. the mating part of the header will allow that to Just clear :) Jan 13 01:06:09 I don't think they would have left something like that to be an issue Jan 13 01:06:33 Thanks vermit...don't have a CAPE yet so I was not sure. Jan 13 01:06:50 most pin headers have a plastic "seat" which holds the pins at their spacing Jan 13 01:07:08 so this spaces the board from the matching socket header Jan 13 01:08:58 I thought I saw in some doc where the expansion header mounted from the top down therefore no plastic seat...I will have to check, not sure. Jan 13 01:09:41 rocky1234.. not on the capes I've seen :) Jan 13 01:12:06 Fund it, page 107 of the reference manual, talks about "stacked cape expansion header" and the diagram they show indicates the CAPE sits flat on the P8 & P9 connector. Jan 13 01:13:32 rocky1234.. yes I suppose stackables would .. but I haven't seen a whole lot of stackable capes personally Jan 13 01:15:03 Well if this becomes a problem I will have to desolder it cut it short and reinstall.....thanks for the input veremit Jan 13 01:15:19 yea fraid so Jan 13 01:22:54 veremit, i now see something on my lcd! but its quite flickery and also, it looks cut-off, because the cursor is not in the middle but in the right bottom corner. so the resolution within X11 seems to be wrong Jan 13 01:23:24 also, xrandr still reports cant open display Jan 13 01:23:35 if the framebuffer is set right - should use that resolution Jan 13 01:23:43 did you check in dmesg ? Jan 13 01:24:07 yes, but i cant find anything interesting Jan 13 01:24:17 do you have a keyword to look for? Jan 13 01:24:33 did you look in /var/log/Xorg.0.log Jan 13 01:24:57 [ 0.673944] [drm] forcing HDMI-A-1 connector ON [ 0.673962] [drm:drm_fb_helper_parse_command_line], cmdline mode for connector HDMI-A-1 640x480@60Hz Jan 13 01:25:04 this looks good Jan 13 01:25:15 will check Xorg log Jan 13 01:25:37 did you put the 'M' in your video= line? Jan 13 01:25:50 ie. 640x480M@60e ? Jan 13 01:26:12 some say MR-@ Jan 13 01:26:15 yes Jan 13 01:26:18 ok Jan 13 01:26:33 root@beaglebone:~# cat /proc/cmdline console=ttyO0,115200n8 quiet drm.debug=7 video=HDMI-A-1:640x480M@60e root=/dev/mmcblk0p2 ro rootfstype=ext4 rootwait Jan 13 01:26:44 looks good Jan 13 01:28:10 so you're sure you got the display parameters correct and all your wiring is rght? :) Jan 13 01:28:29 that you've got Something is a good start Jan 13 01:28:47 this is my Xorg.0.log: http://pastebin.com/Hspn6MDC Jan 13 01:29:28 line 93... seems interesting Jan 13 01:30:23 129 does look worrying Jan 13 01:30:28 thing i dont understand: in kernel args, i use HDMI-A-1 and in X11 logs, it's HDMI-0 Jan 13 01:30:52 ahh 100 iswrong Jan 13 01:30:53 270x203 lol Jan 13 01:31:37 you see the console on the screen? Jan 13 01:31:49 and the logo Jan 13 01:31:51 no, the gnome desktop Jan 13 01:32:03 while booting, it is black Jan 13 01:32:04 when it boots I mean Jan 13 01:32:07 ah Jan 13 01:32:26 you might wanna check that parameter Jan 13 01:32:41 you should see the usual 'blah' Jan 13 01:32:56 thats probably why you X resolution is bad Jan 13 01:33:12 unless you fix it in an xorg.conf file Jan 13 01:33:49 ours works fine at boot Jan 13 01:33:54 strange Jan 13 01:33:58 we have a spashscreen Jan 13 01:34:22 check the syntax of that video line Jan 13 01:34:25 i dont :( seems it ignores the 640x480 part Jan 13 01:34:42 yeah something not right there then Jan 13 01:34:51 optargs=quiet drm.debug=7 video=HDMI-A-1:640x480M@60e Jan 13 01:36:59 looks ok to me Jan 13 01:37:13 unless somthing odd in dmesg Jan 13 01:37:44 did you post a dmesg? Jan 13 01:38:06 no, one moment Jan 13 01:38:55 it should tell you what res its setting Jan 13 01:45:52 http://pastebin.com/i6Xav3VJ Jan 13 01:46:44 line 303 Jan 13 01:48:54 actually, it looks like it's doing the same lines over and over again o.O Jan 13 01:51:30 yea thats quite odd Jan 13 01:51:41 only does that loop once for me Jan 13 01:52:22 meh Jan 13 01:55:48 can you check your board if your xrandr outputs anything except "cant open display"? Jan 13 01:56:12 will look tomorrow Jan 13 01:57:05 ill check back here tomorrow evening europe TZ Jan 13 01:57:16 need sleep now (3am) Jan 13 01:57:19 kk Jan 13 01:57:27 thanks for your help!
