Jul 03 03:48:35 <_av500_> and ancient castle Jul 03 03:48:41 <_av500_> up on a hill Jul 03 03:53:09 * ds2 drains _av500_'s moat Jul 03 03:53:42 <_av500_> it does not have one Jul 03 04:12:06 what castle doesn't have a moat? tsk tsk Jul 03 04:45:18 hi i am using beaglebone. would somebody help me? Jul 03 04:46:47 i want to use adc on android Jul 03 04:47:08 but i cannot find adc device driver in android kernel Jul 03 05:07:00 <_av500_> mranostay: one on a steep hill Jul 03 05:10:54 echo c >/proc/sysrq-trigger Jul 03 05:12:20 (don't do this) Jul 03 05:39:37 Hey Folks! I had a quick question. I have a BeagleBoard-xM and have an Ubuntu running on it right now. I wanted to access the onboard ADC and was wondering if anyone had any references/sample code to get me jump started. Jul 03 05:45:13 In fact, I am not even quite sure if the BeagleBoard-xM has an ADC onboard Jul 03 05:47:01 we need a counter for "quick questions" and every 100 we should offer a quick answer. Jul 03 05:52:02 WebcamWonder: have a look at the SRM to check if an ADC is there (and available on the expansion connector) Jul 03 05:52:40 I would assume there is at least one. Jul 03 05:55:29 aholler: There seems to be one and from the looks of it, the Linux kernel seems to have the appropriate patches too. I just can't find the mapped file in /sys/. Perhaps the Kernel I am using doesn't have the ADC support compiled. Trying to research this on Google right now but turning up very little useful info Jul 03 06:06:06 _av500_: so you live in Darmstadt? Jul 03 06:11:06 WebcamWonder: zgrep CONFIG_option_you_found_in_the_patches /proc/config.gz Jul 03 06:21:07 aholler: I checked that and it seems to be a "y" and it is confusing the heck out of me =/ Jul 03 06:21:32 s/checked that/checked that already/ Jul 03 06:23:19 Too much sleep-deprived and going to give up on this. Thanks a lot aholler though! Really appreciate it! Jul 03 06:25:30 WebcamWonder: maybe you are looking at patches for the beaglebone Jul 03 06:29:37 gah! Jul 03 06:30:06 wishs people would stop using chinese characters in their names Jul 03 06:30:18 spam filters do not like that.. Jul 03 06:38:04 Russ: a6 should have a bit more space around the mounting holes (according to the changelog) Jul 03 06:52:40 mranostay: yep Jul 03 06:53:30 koen: https://lkml.org/lkml/2012/7/3/57 Jul 03 06:56:07 aholler: thanks! Jul 03 06:56:37 not attaching it doesn't do any harm ;) Jul 03 07:00:17 but it's nice that there are people out there which even are testing panics. If they just would have used a box with a a time set to some point in the feature ;) Jul 03 07:00:49 s/feature/future/ Jul 03 07:01:45 it still makes me wonder that nobody has box a running somewhere with the time e.g. one week ahead Jul 03 07:08:22 aholler: why not morse "PANIC"? Jul 03 07:09:26 aholler: probably they had a box set into the future, but because CONFIG_FLUXCOMPENSATOR was not set, the box is not accessible anymore. Jul 03 07:09:32 av500: would be funny, but I don't think upstream would me let do that ;) Jul 03 07:10:15 they even complain about spaces after ( Jul 03 07:10:44 av500, how many people *know* morse? Jul 03 07:11:00 sos shoud be known by most people Jul 03 07:15:04 one could try to build a workload which changes the heardbeat to an SOS. Shouldn't be that hard ;) Jul 03 09:42:37 howdy! does anyone have experience developing for the dm3730's DSP? I have a project coming up that would benefit from the DSP's support Jul 03 09:43:13 I will be using linux, and it will be doing some data manipulation from the camera input Jul 03 09:45:26 can anyone recommend tools, build process, etc?.. interfacing - codec engine? Jul 03 10:08:31 Attie: yes Jul 03 10:08:34 can be done Jul 03 10:08:45 codec engine is a good start Jul 03 10:08:52 hi av500 Jul 03 10:08:55 angstrom already has CE integrated Jul 03 10:09:04 so go have a look at the CE examples and get them to run Jul 03 10:09:21 if you manage that, you can start to fill the "dummy" codec with something useful Jul 03 10:09:25 does angstrom have examples online? Jul 03 10:09:35 no Jul 03 10:09:39 there are CE examples Jul 03 10:09:49 if you install angstrom with CE they should be there Jul 03 10:09:57 oh okay Jul 03 10:10:12 you can also download the CE package from TI and look at the examples source code Jul 03 10:10:13 thanks, I'll take a look :) Jul 03 10:10:31 what kind of processing? Jul 03 10:10:41 i thought so, thanks. Jul 03 10:10:54 it's a matter of splitting the incomming stream into 4 frame buffers Jul 03 10:10:59 hmm Jul 03 10:11:01 and? Jul 03 10:11:05 why a DSP for that? Jul 03 10:11:29 the stream goes like so (in byte-terms) ABCDABCDABCD.... Jul 03 10:11:37 yes Jul 03 10:11:40 so we need to split that out into AAA BBB CCC DDD Jul 03 10:11:55 should be doable in neon Jul 03 10:12:01 yup Jul 03 10:12:03 it could be done on the ARM core, but that takes processing power away from the openCV application that will be running there Jul 03 10:12:05 its most memory limited Jul 03 10:12:26 Attie: what resolution? Jul 03 10:12:41 its 4x cameras, each 640x480 @ 15fps Jul 03 10:12:48 hmm Jul 03 10:13:02 should be doable Jul 03 10:13:08 v4l2 camera? Jul 03 10:13:15 with neon? Jul 03 10:13:20 i'm just checking that now Jul 03 10:13:31 or via ISP/CCDC? Jul 03 10:13:45 for v4l2, kernel is touching the data anyway Jul 03 10:13:55 so it could split it there already Jul 03 10:14:21 they are OVM7690 cameras Jul 03 10:14:26 or let the kernel handle raw data and split it later on in userspace Jul 03 10:14:42 Attie: and some fpga I guess to mux the images Jul 03 10:14:46 so ISP/CCDC Jul 03 10:14:49 yep indeed Jul 03 10:14:53 sorry,no idea with v4l2 Jul 03 10:15:02 maybe you could even do the split with DMA Jul 03 10:15:10 program the correct stride and offset Jul 03 10:15:11 or so Jul 03 10:15:28 i'd contemplated that... but the memory overhead gets a little scary Jul 03 10:15:44 overhead? Jul 03 10:15:45 i think i calculated close to 300MB/s to bring it in, and split it Jul 03 10:15:52 not 'overhead' but usage Jul 03 10:15:55 don't worry about memory overhead.....frames can be manipulated easily in neoan Jul 03 10:16:10 well, you need to touch the data anyway at some point Jul 03 10:16:13 i think i need to look into neon Jul 03 10:16:15 so there you can split it Jul 03 10:16:23 id not thought of it Jul 03 10:16:28 its the same mem BW for the whole frame or the 4 parts Jul 03 10:16:53 you sure about that? Jul 03 10:17:37 the camera interface takes data in, and stored it into main memory. then you need to read 1 in 4 bytes, and store to a frame buffer (4x times) Jul 03 10:18:05 u mean take only A out of ABCD? Jul 03 10:18:16 for frame / camera A Jul 03 10:18:23 B relates to a different camera Jul 03 10:18:35 yes Jul 03 10:18:49 can be done...see neon intruction..... Jul 03 10:19:05 there use diffeerent strides options Jul 03 10:19:11 ok, thanks! i'll do some reading and may come back Jul 03 10:27:25 Hi! How can I test the latest kernel (linux-omap) with BeagleBone support? AFAIK device tree plays the tune and in the master branch, the dts file has only definitions for 3 i2c busses. But only their frequences. I have found various places with patches to apply and compile, but the stuff is 3.2 specific. Jul 03 10:34:20 Attie: maybe there is a way not to commit the initial data to main memory Jul 03 10:34:40 thats what I was thinking initially Jul 03 10:34:49 get the line dumped into the DSP's memory Jul 03 10:34:59 then have the DSP split it and write out to main memory Jul 03 10:35:00 but even then, in a typical video encoding case, frame data is read/written more than once Jul 03 10:35:16 so there is memory bandwidth Jul 03 10:35:27 decoding H264 720p is much worse wrt to that Jul 03 10:35:31 and is doable Jul 03 10:35:43 of course, I have no idea what your openCV does Jul 03 10:35:49 do you have any idea what the avaliable bandwidth on a beagleboard is? Jul 03 10:35:51 but I predict that will be the bottleneck Jul 03 10:35:57 Attie: I had but forgot Jul 03 10:36:04 ok Jul 03 10:36:12 consider about 60% of theoretical Jul 03 10:36:23 (TI hates me for saying that :) Jul 03 10:37:20 to a point openCV is the customer's problem, we just need to get them pictures :-) Jul 03 10:37:43 on the other side, i'm trying not to use up all the available everythings getting them the pictures Jul 03 10:42:19 ic Jul 03 10:42:25 yegorich: ignore mainline and/or linux-omap for the next 6 months Jul 03 10:42:48 koen: you know how long that is in internet years? Jul 03 10:42:55 3.5ys Jul 03 10:47:46 av500: and that 6 months is an optimistic estimate Jul 03 10:48:12 koen: what is going on? Jul 03 10:48:25 all arm or 335x? Jul 03 10:48:26 av500: anyway, I was told to stop hating on the crappy am335x support, so I'll do that Jul 03 10:48:46 koen: <3 <3 <3 it Jul 03 10:56:39 av500: no, 3 is not less than 3 Jul 03 10:56:55 although in C, "3 < 3" is indeed < 3 Jul 03 10:57:42 koen: I can't :-( I have some i2c issue and Shubhrajyoti Datta suggested me to test the latest kernel because lots of i2c related patches were committed Jul 03 10:59:39 koen: AnilKumar submitted a patch for device tree and Tony should integrate it into devel-dt branch, but the stuff is not there yet, so I'll have to apply the patches myself and test the stuff. Jul 03 10:59:52 ola Jul 03 11:00:03 I don't understand something with wifi Jul 03 11:00:32 if I disable connman, and connect using ifup wlan0, it works Jul 03 11:01:12 when I restart connmand (after ifdown wlan0)or reboot, connmand just says ADDRCONF(NETDEV_UP): wlan0: link is not ready Jul 03 11:01:55 I don't get it, and I'd like to use dbus to configure the wifi with a configuration interface coded in python Jul 03 11:01:58 ... Jul 03 11:02:26 (connman rock on the paper, but it just sucks on the filed) Jul 03 11:02:29 field* Jul 03 11:17:08 yegorich: for the next 6 motnhs you'll only get ramdisk working as rootfs in linux-omap/mainline Jul 03 11:53:15 io is now totally dead? ;) Jul 03 11:54:51 hmm, kde 4.8.4 compiled here ;) Jul 03 12:03:00 koen, unless you use pending patches, of course Jul 03 12:12:34 what's wrong with io? :P Jul 03 12:24:09 mdp: I'll try this and we will see what is really working. Jul 03 12:24:40 mdp: what will be better to make pinmux in u-boot or via pinctrl driver? Jul 03 12:34:47 kernel Jul 03 12:35:58 /dev/mem Jul 03 12:42:49 hi all, I want to buy beagle board for learning board bringup and device drivers... Are resources available for the same ? Or it can only be used for higher level application code writing only ? Jul 03 12:43:17 no Jul 03 12:43:26 it can be used for a lot of things Jul 03 12:43:37 resources are all over the internet Jul 03 12:43:44 starting from beagleboard.org Jul 03 12:43:46 elinux Jul 03 12:43:48 google Jul 03 12:44:49 I already have a mini2440(ARM9 based).. but it does not have big community support as beagle board has.... Jul 03 12:45:45 I have googled but could not get some guide like: linux porting on beagle board.... Jul 03 12:46:07 porting ... ? what ? Jul 03 12:46:24 I want to know from scratch how the linux was ported for beagle board.. Jul 03 12:47:07 Same way as any port, I imagine. Jul 03 12:47:11 i highly doubt such a document exists since you would have to go back of several years Jul 03 12:47:18 starting from taking a vannila kernel and adding board specific code Jul 03 12:47:35 A good share of that may well have been done by TI. Jul 03 12:47:50 there is a movie coming about porting of linux on beagleboard this summer.....ice age 4:port linux Jul 03 12:47:59 I too agree to that...but beagle board being such popular board for learning should have this Jul 03 12:48:08 rkc_: Why? Jul 03 12:48:17 rkc_: that's basically copying board-sdp3*.c to board-beagle.c, fix gpios/memory and such Jul 03 12:48:26 add the mtype Jul 03 12:48:31 change Makefile/Kconfig Jul 03 12:48:46 and pray that there is no #ifdef BOARD_BEAGLEBOARD everywhere in the code Jul 03 12:48:56 And if there is, refactor it. Jul 03 12:49:13 I understand... but for a beginner like me if a step by step doc is available then it helps Jul 03 12:49:35 rkc_: But you have no need to port Linux to the BeagleBoard--it has already been done. Jul 03 12:49:48 So a tutorial on it serves no purpose. Jul 03 12:49:54 apart from that I never found any doc related to linux porting with a complete example Jul 03 12:50:09 Because porting is done rarely and by small, dedicated groups. Jul 03 12:50:22 rkc_: true, they do not exist Jul 03 12:50:40 It may be needed for the people working on low level firmware and device drivers which wants to make a shift to Linux Jul 03 12:50:55 there are enough who manage without a guide Jul 03 12:51:07 and its learning on-the-job Jul 03 12:51:22 nobody starts by porting linux to XYZ Jul 03 12:51:34 unless he worked on linux on ABC before Jul 03 12:51:38 you know that is the biggest blocker for peop;le like us to join linux community.... there's no such doc for even one example board... Jul 03 12:51:45 true Jul 03 12:51:53 but there is nobody to write them either Jul 03 12:51:58 feel free to contribute Jul 03 12:52:09 one cannot demand from a community Jul 03 12:52:41 rkc_: There is a major difference between porting Linux (a full operating system) and porting a program or a driver. Jul 03 12:52:56 The latter concept is moderately well-documented here and there across the Internet. Jul 03 12:54:39 guyz lets not go on to shooting the messenger stuff... I do use mini2440 and I do help other beginners to learn Jul 03 12:55:09 we dont shoot anybody Jul 03 12:55:12 so question is I am not equipped to write a linux porting guide else I 'd have loved to do Jul 03 12:55:14 rkc_: Who is shooting what messenger? All we are saying is the reasons what you are asking for does not exist. Jul 03 12:56:47 The Linux "community" is a large, fragmented collection of primarily highly-individualistic folk who volunteer to write things because it interests them. If something does not exist as a product of said community, it means that either (or both) no one had time for it or no one was interested in it. Jul 03 12:56:57 since you do not have a need you say its not needed.... I hope beagle board is also a learning platform for all...not only the people who take already ported kernel and use it Jul 03 12:57:12 it can be a lot of things Jul 03 12:57:20 THe way you solve this is to do it yourself, or convince someone else to give up one of their other interests or committments and do it for you. Jul 03 12:57:24 but the "product" you buy is only the hardware Jul 03 12:57:35 I'm one with a need to learn linux porting....whats wrong in that Jul 03 12:57:40 you do not buy support or SW or extensive docs Jul 03 12:57:48 rkc_: nothing wrong with that Jul 03 12:57:50 Nothing, but this is the wrong forum to look for that information. Jul 03 12:57:53 there are enough arm-boards in the kernel-tree with much less stuff than an omap. just use one of those boardfiles as a start Jul 03 12:58:13 and don't use a monster like omap Jul 03 12:58:23 For information on linux porting, I suggest you talk with a group that does porting of linux. Jul 03 12:58:41 if such a group can be identified Jul 03 12:58:49 thats the issue Jul 03 12:58:51 even I do "porting" Jul 03 12:58:51 xda - cookers Jul 03 12:59:03 but not all of linux to brand new hardware Jul 03 12:59:05 The TI developers for the BeagleBoard. Jul 03 12:59:14 there are none Jul 03 12:59:19 beagle is not a TI product Jul 03 12:59:40 av500: There are a few folk who work for TI also active in the BeagleBoard community. Jul 03 12:59:45 yes Jul 03 12:59:56 One of them does pretty regular presentations at my local hackerspace. Jul 03 13:00:06 who is that? :) Jul 03 13:00:08 Thus, TI developer--as in, a developer, from TI. Jul 03 13:00:19 There are two parts of porting.... 1) Chip manufacturer provides port for their processor 2) different board vendors provide board specific port Jul 03 13:00:20 Mmm...let me see if I can come up with the name. Jul 03 13:00:28 I need to learn 2nd one Jul 03 13:00:45 rkc_: So talk to a board vendor? ;-P Jul 03 13:00:55 rkc_: we do that all the time at $work Jul 03 13:01:01 but we dont have a guide, just experience Jul 03 13:01:21 av500: Jason Kridner Jul 03 13:01:30 jkridner... Jul 03 13:01:47 but I would not label him as a boardporter Jul 03 13:02:08 No, but he was involved in it. Jul 03 13:02:18 av500: then you are my man... pls help me understand how to go about it... Jul 03 13:02:39 I think phh did a nice job explaining it a while ago. Jul 03 13:02:56 rkc_: sadly I have to $work :) Jul 03 13:03:54 :-( Jul 03 13:04:15 but irc is not the place to get a turorial Jul 03 13:04:26 ask specific questions and they might get answered Jul 03 13:04:39 asking "how do I port?" gets you nowhere Jul 03 13:04:47 Agree Jul 03 13:06:11 rkc_, You might want to try "Write linux porting guide" here: http://aws.amazon.com/mturk/ Jul 03 13:06:42 well Jul 03 13:06:47 no need to mock him Jul 03 13:08:03 well thx jsabeaudry... I appreciate the link ;-) Jul 03 13:08:07 Oh, now I have seen everything, av500 getting offended at a joke on this channel ha! Jul 03 13:08:27 well, I did not want you to have an incomplete experience here Jul 03 13:08:48 lol Jul 03 13:09:29 ok... so there are multiple beagle configurations availale Jul 03 13:09:41 which one should suit me.. Jul 03 13:09:48 get the XM Jul 03 13:10:18 any specific reason for this... Jul 03 13:10:27 it has the most Jul 03 13:11:02 does it have any revision ...like rev c... Jul 03 13:11:33 yes, but you will get the latest Jul 03 13:12:35 does xM come with any LCD...3.5" ? Jul 03 13:12:54 rkc_, not out of the box Jul 03 13:13:04 no lcd Jul 03 13:13:58 what about beaglebone... Jul 03 13:14:01 rkc_: There are LCDs you can buy for the xM, but it does not come with one. Jul 03 13:14:07 That even less so. Jul 03 13:16:41 Does beagle board support openocd for HW jtag? Jul 03 13:17:14 the other way round Jul 03 13:17:20 does openocd support the beagle board Jul 03 13:17:30 I think it does Jul 03 13:17:39 what did google say? Jul 03 13:17:58 I have one which I use with ARM9 mini2440 board Jul 03 13:18:03 http://www.google.de/search?sourceid=chrome&ie=UTF-8&q=openocd+beagleboard Jul 03 13:18:45 But I guess A8 is a high end AP so my Jtag Hw might not support it Jul 03 13:18:56 what hw? Jul 03 13:19:01 Literally the first result for "beagleboard openocd" is http://elinux.org/BeagleBoardOpenOCD Jul 03 13:19:01 we cannot tell Jul 03 13:19:36 rkc_: If there is one site other than Google that will help you the most with what you are trying to do, it is http://elinux.org. Jul 03 13:20:47 agmlego: thx; I already have it in my bookmarks :-) Jul 03 13:21:21 rkc_: Most, if not all, your questions regarding embedded Linux, on the BeagleBoard or other platforms, are probably already answered there. Jul 03 13:23:18 agmlego: I have it in bookmarks... but I never browsed it extensively.... after your remarks I'm certainly going to use it most often Jul 03 13:25:41 e Jul 03 13:25:53 f Jul 03 13:26:37 av500: I have the cheapest of them all...its here: http://www.olimex.com/dev/index.html Jul 03 13:32:53 hi...am i connected still ? Jul 03 13:33:01 looks like yes Jul 03 13:49:02 one could write a book "Harry Porters" ;) Jul 03 13:49:22 s/Harry/Hary Jul 03 14:03:57 hairy? Jul 03 14:04:19 hail the porter Jul 03 14:11:21 the longer the beard the better the porter ;) Jul 03 14:42:06 koen: I've realized I've always misinterpreted the '-c' of MKUBIFS_ARGS. I'll just take the largest for Narcissus config files. Jul 03 15:15:09 has anybody here had experience with mixing high and full speed usb devices on a bbxm? does the high speed device slow down to full speed? Jul 03 15:16:41 usb is, despite the name, a point-to-point link Jul 03 15:17:06 a hub multiplexes multiple downstream endpoints onto its upstream link Jul 03 15:17:29 the downstream links can run at different speeds Jul 03 15:17:43 there is a kernel-option you can play with Jul 03 15:17:54 if you really have problems Jul 03 15:17:55 the transaction translator stuff? Jul 03 15:18:00 yes Jul 03 15:18:04 not applicable Jul 03 15:18:31 the only thing connected to the host controller is a high-speed hub Jul 03 15:19:07 right Jul 03 15:20:38 of course a slow device will eat more of the shared link between host and hub to do the same job compared to a fast device Jul 03 15:20:47 bobsickle: and wothout knowing the device, nobody could really answer. low-speed stuff usually are mice or keyboards, they are that slow that a speed degratation of the hs-bus shouldn't be measurable Jul 03 15:21:12 s/bus/stuff/ Jul 03 15:22:43 ok, I basically want to know whether attaching a : you have my condolences Jul 03 15:22:47 argh Jul 03 15:22:50 putty fail Jul 03 15:22:59 I am sorry for your loess Jul 03 15:23:03 -e Jul 03 15:23:53 ok, I basically want to know whether attaching a MCP2210 usb-to-spi chip (full speed usb at 12mbps) will affect the speed of a foo-yip uvc camera Jul 03 15:24:42 try and find out Jul 03 15:25:33 yeah I read about the transaction controller stuff but I swear I've read elsewhere that attaching a slower device will make everything run slow Jul 03 15:25:46 does it work on your pc? Jul 03 15:25:50 easy test Jul 03 15:26:20 I haven't actually got the usb-spi yet Jul 03 15:26:35 I'm designing a peripheral board Jul 03 15:26:53 so I'm totally open to suggestions here Jul 03 15:27:51 where peripheral == 12 servos, 2 motors, 16 GPIO, 6 analog in Jul 03 15:33:26 so why do you need usb2spi? Jul 03 15:33:31 the panda *has* SPI already Jul 03 15:33:52 I'm using a bbxm because of its dimensions Jul 03 15:35:02 I'm doing a new controller for these http://robotics.ee.uwa.edu.au/eyebot/ Jul 03 15:35:03 xM has SPI, I thought. Jul 03 15:35:37 and I'm trying to make it easily modular, so the interface to the IO board I'm making must be usb Jul 03 15:35:59 I know this sounds roundabout, but there is method to my madness Jul 03 15:36:20 well, usb is fine too Jul 03 15:36:30 saves you the hassle of pinmux and level shifters :) Jul 03 15:39:24 yeah the last guy who tried what I'm doing did all the IO on a gumstix expansion board. By the time they worked out the bugs in it, the COM had been discontinued Jul 03 15:40:02 yay university students! Jul 03 15:40:15 (I'm one too btw) Jul 03 15:41:12 ooher, I might be able to avoid the problem altogether with an FT2232H Jul 03 16:36:57 hey Jul 03 16:37:02 how do I reset the journalctl ? Jul 03 16:38:09 howdy, I have a question regarding I2C on beagle Board xM trainer board... :) can anyone assist :) Jul 03 16:40:33 waltermixxx: ask, dont ask to ask Jul 03 16:41:11 "quick questions" are trendy ;) Jul 03 16:42:25 okie doke... :) Jul 03 16:43:47 is I2C working by default on the xM trainer board by default, or do I have to recompile the kernal to get it working? I suspect it is working, so it can read the little eprom on expansion cards, but is it fully accessible Jul 03 16:44:19 I'm wondering how I would read data from it... Jul 03 16:44:39 i will have a look at the nunchuck example and see if it answers my questions. :) Jul 03 16:44:55 i guess I was wondering if anyone has experience with it :) Jul 03 16:46:11 Hey everyone! I wanted to try a first example with beaglebone, and I was looking for a tutorial about how to make a blink program with the onboard LED, but I couldnt find any. Does anyone know where can I find one? Jul 03 16:46:28 are there any professional embedded linux engineers in here? Jul 03 16:46:46 i think everything I need is in the nunchuck example... I will paruse it first :) Jul 03 16:47:07 but it would be nice to know if anyone has already gone through it :) Jul 03 16:47:09 cheers Jul 03 16:50:15 SmashLink: blinking a LED is something that can be googled Jul 03 16:51:17 youtube also have a few video's on beaglebone and blinking leds. Jul 03 16:51:55 this dude is awesome: http://www.youtube.com/watch?v=z6b4zlh0IrE Jul 03 16:51:57 there are literal thousands of howtos on this Jul 03 16:52:02 *literally Jul 03 16:52:04 he has several tutorials... Jul 03 16:53:37 i may pick up a beaglebone as well ( I have a beagle board xM currently, which rocks...) I like the hackability of it, and the communitee around it appear to be more Hacker based? :) Jul 03 16:54:14 refering to the beaglebone that is :) miss placed modifyer... (grammer et all) Jul 03 16:54:16 hacker based rather than? Jul 03 16:55:45 not sure, I get a good hacker vibe from the beagle bone community ... I think the beagle board folks may be a bit more serious? but that is an impression, not a fact and not meant to upset anyone :) Jul 03 16:56:03 wont upset anybody Jul 03 16:56:10 having both I think would be cool :) Jul 03 16:56:10 and the crowd is mostly compatible Jul 03 16:56:23 lol :) i think you are right Jul 03 16:56:36 either way both platforms rock... Jul 03 16:56:46 certainly :) Jul 03 16:58:20 SmashLink should have no issues finding resources for beaglebone. :) and here is a good place to ask questions should one need help...( assuming one has done some googling and reading first..me included....which I did shortly after I asked my question... :) Jul 03 16:58:28 yes, it's impressive how many computation power is needed to make leds blink ;) Jul 03 16:59:44 well it's the start, once one knows one can, then linking them to a webserver is the next step, that's where the computational power comes in...multiple socket connections, monitoring different things.. :) Jul 03 17:01:01 all in one package vs arduino and computer combination :) Thats why I love this trainer xM add on board... arduino built in ( incase it's needed ... ) :) Jul 03 17:02:26 where would I post a picture of my handy dandy beagleboard xM with Trainer xM board on my home made plexy-glass base? :) Jul 03 17:02:58 I guess i could use flicker then post a link to it :) Jul 03 17:03:44 I've seen many many tutorials on how to blink an external LED, but none of how to make the onboard one working... well, actually, i've seen one written in C, but I don't know how to compile C in the beaglebone yet Jul 03 17:04:00 I will check this video, thanks waltermixxx Jul 03 17:04:39 this guy has lots of tutorial video's one built upon the last Jul 03 17:05:27 so watch them in order, they are pretty long, but very informative... :) Jul 03 17:07:07 oh, damn, I didn't check the cloud9 examples... i'm gonna do this right now Jul 03 17:07:15 Great video, btw Jul 03 17:07:31 * djlewis anxiously awaits pizza delivery Jul 03 17:10:50 hey all, is there anyone else running debian on their beagle board out there right now? Jul 03 17:11:45 i'm getting errors on running the blinked.js example, you know anything about this? It says it can't find the resource 'bonesript' Jul 03 17:12:41 jmonk, 24/7... need something? Jul 03 17:13:00 just have a wierd issue where i can't get my console to go over the serial port Jul 03 17:13:15 works fine with other distributions i've run on it, but not squeeze Jul 03 17:13:23 seems to be independent of kernel Jul 03 17:13:36 /etc/iniitab should be enough.. http://elinux.org/BeagleBoardDebian#Serial_Ports Jul 03 17:13:56 and as long as it's also in the bootargs.. console=ttyO2,115200.... Jul 03 17:14:07 yeah thats what i have Jul 03 17:14:29 and i tried both ways on your link (despite the fact i'm running squeeze) Jul 03 17:14:51 is it possible i did something somewhere else to screw it up? Jul 03 17:15:27 there really isn't anywhere it can be messed up... specially if it's in that file... it's not defined twice or anything? Jul 03 17:15:39 hmm, didn't check for that Jul 03 17:15:42 give me a second Jul 03 17:15:45 and it's O as omap and not 0 as in zero? Jul 03 17:16:02 oh, really? Jul 03 17:16:57 maybe i typed it wrong Jul 03 17:17:14 (it's an easy mistake that's made a lot on the mailing list..) Jul 03 17:18:04 that might have done it, i'm in the middle of a couple things, but hopefully when they are done I won't have any more issues Jul 03 17:18:44 so in the boot args its an O as well not a 0? Jul 03 17:19:17 yeap, it's O in both... think tty Omap #port number.. Jul 03 17:21:02 that worked great, thanks Jul 03 17:21:37 no problem. ;) Jul 03 17:22:40 i seem to get these io error after intense writing/reading for a while, you thinks its likely i have a faulty sd card a few weeks after it being brand new? Jul 03 17:23:27 nah, ubuntu/debian can be a little rough on sd cards... are you using ext3/4 or btrfs? Jul 03 17:23:35 ext3 Jul 03 17:24:05 enable noatime in fstab.. Jul 03 17:24:15 will do Jul 03 17:24:53 that'll help a little... for most of my systems, i bypass the sd card fully, and just run the main os on an external usb sata drive.. Jul 03 17:25:17
