Oct 01 09:17:39 hey i have a question Oct 01 09:17:50 is somone there? Oct 01 09:18:04 or her Oct 01 09:18:09 :) Oct 01 09:19:36 no, we all went to #pandaborad Oct 01 09:20:21 ..wait for his answer he gives on #pandaboard Oct 01 09:21:14 lol Oct 01 10:28:45 hey I'm new around here and would like to contribute Oct 01 10:28:52 someone please help me Oct 01 10:29:31 step 1: do not ask for help, but help other people Oct 01 10:29:41 step 2: find something that interests you and work on it Oct 01 10:29:45 step 3: ... Oct 01 10:29:48 step 4: profit Oct 01 10:38:20 hey I'm new and I'd like to contribute Oct 01 10:39:18 ksk_: in which area? Oct 01 11:06:00 area 51 Oct 01 11:13:26 Hi.. has anyone tried to connect BBB to D-Link router via ethernet.. I am not getting the connection with BBB but with BB white everything is perfect Oct 01 11:15:07 hmm Oct 01 11:15:17 nothing special about dlink Oct 01 11:15:45 I think my router is D-Link, actually, and I haven't had any problems Oct 01 11:15:50 I'd have to double check Oct 01 11:16:16 i'd check the cable/plug Oct 01 11:16:17 etc Oct 01 11:16:24 also, serial console and dmesg Oct 01 11:16:34 or ssh over USB and dmesh Oct 01 11:16:36 dmesg Oct 01 11:16:38 the usual Oct 01 11:16:45 oh, it's netgear, my mistake Oct 01 11:16:54 if DHCP, does the BBB get an IP? Oct 01 14:40:56 Hey, I'm new here. An aspirant of Gsoc and would like to contribute Oct 01 14:41:03 please help me Oct 01 14:41:52 .o0(is it that time again?) Oct 01 14:42:50 Hey I'm new and would like to contribiute Oct 01 14:42:51 deja vu Oct 01 14:43:00 I'm an aspirant og GSoc Oct 01 14:43:20 Please guide me through Oct 01 14:44:28 um, isn't gsoc 2014 over by now? Oct 01 14:44:36 .. and 2015 still a bit away Oct 01 14:45:31 hm he seems confused a lot Oct 01 14:46:22 well confusion itself is not necessarily bad. Oct 01 14:49:26 there is WSoC Oct 01 14:49:29 winter is coming Oct 01 14:49:39 you mean gwoc, then. Oct 01 14:49:41 in WSoC you pay $5k to work on open source Oct 01 14:51:25 applications welcome Oct 01 14:53:40 wsoc, winter summer of code? Oct 01 14:54:09 meh Oct 01 14:54:18 GWOC then Oct 01 14:54:23 :P :) Oct 01 14:54:27 well i told you ;) Oct 01 14:54:35 DO I LISTEN!!!! Oct 01 15:03:37 Hello People Oct 01 15:04:56 Hello! I am people Oct 01 15:05:34 hi people, i'm KotH Oct 01 15:08:03 har Oct 01 15:59:42 My terminology will be incorrect with the description of what I am trying to do. I attempted to write a bootable image of FreeBSD to a BBB by pressing and holding the boot switch for ten or so seconds. The write process did not start. However, using the same process with both Debian and Ubuntu worked. Oct 01 16:01:06 Does anyone know of any resources describing the firmware update capabilities and / or processes? I want to see if there is some reason I was unable to write a FreeBSD image to the BBB and fix it if I can. Oct 01 16:02:07 VirG: the freebsd image you tried to flash was built for the bbb? Oct 01 16:02:14 Yes Oct 01 16:02:29 I can boot it from SD. It has been running for several days now. Oct 01 16:03:24 the boot switch just forces boot off of SD, it doesn't trigger any sort of flashing mode Oct 01 16:03:55 VirG: so your freebsd image would have to handle the flashing Oct 01 16:04:29 that's why there's a separate image for running off of SD and flashing Oct 01 16:05:43 I see. Oct 01 16:05:44 OK Oct 01 16:06:16 I thought that was triggered by the boot button as the instructions I followed specified holding the boot button until the LEDs start flashing. Oct 01 16:08:23 the flashing is just a script though, AFAIU Oct 01 16:18:36 With that in mind I am searching for descriptions of how flashing works and what the requirements are. Oct 01 16:18:37 thanx Oct 01 16:25:14 Hey all, new guy here just getting started with the BBB rev c. Quick question: It seems that the initial "Getting Started" tutorial really tries to sell the Cloud9 IDE. Does anyone here really use that or is it more cramware when we're talking about higher level programming? Oct 01 16:40:31 RedWolf: I think it depends on your level of experience and background. I'm a self-identifying C programmer, so I wasn't interested in Cloud 9. That said, I did try it, and found it to be cool how quickly you could perform some actions (like the Arduino IDE). Oct 01 16:40:55 RedWolf: That said, besides the test run, I don't use it. But I don't think I'm the intended auidence. Oct 01 16:41:41 * jbdatko_ needs to watch his "that said" usage... Oct 01 16:43:56 I used it once to regenerate a broken ssh private key that dropbear had made Oct 01 16:44:07 so I guess it's not completely worthless? Oct 01 16:44:57 jbdatko_: Thanks for your input on it anyway though. I'm more of a python and c# kinda guy, so it's definitely going to take a bit for me to power through all the initial low level stuff that I know very little about. It's all about learning though, so no complaints here Oct 01 16:45:57 torque: So do you find it has a lot of limitations? Oct 01 16:47:19 well, the bonescript interface for javascript makes it very easy to quickly pick up and learn how to use the the IO capabilities of the bbb Oct 01 16:48:33 though I probably wouldn't use the cloud9 ide even if I were writing javascript because I have a perfectly fine editor on my computer that I much prefer Oct 01 16:49:58 Haha, yeah I saw that. I went ahead and wrote a little mini library for myself to just be able to do that in python without having to write to the files. My ultimate goal is setting up OpenNI to get kinect depth data Oct 01 16:51:09 and I really don't see cloud9 being any more useful than a custom ide where I develop and then just sftp files into a some folder that runs on startup with a service Oct 01 16:51:23 Thanks for your help though. I appreciate it Oct 01 17:04:49 Anyone ever tried running Docker on a BBB? Is that even a good idea? Oct 01 17:21:57 good afternoon guys, does anyone knows if its possible using beagleboard black make a real-time data aquisition by an 8ch ADC in parallel processing of these data Oct 01 17:23:31 hello, Im looking for a compact system based on BeagleBoard for survival kits, like very-low-consumption small screen with a small keyboard attached, preferably with AA batteries, running all the system for some 4 hours or so. Do you think it is possible? Where can I learn more about such a system? Oct 01 17:23:41 good afternoon guys, does anyone knows if its possible using beaglebone black make a real-time data acquisition by an 8ch ADC and a parallel processing of these data Oct 01 17:27:30 EddyUFCG: YOu might want to have more than two minutes' patience. Oct 01 17:30:43 EddyUFCG: that will depend on how much data Oct 01 17:31:37 Aytac_: there are battery capes for the BBB Oct 01 17:32:19 Aytac_: essentially using something like the lapdock with the BBB will get you there too Oct 01 17:33:19 tbr: can we add more than one cape? i saw also touchscreen capes but thought they use the same slot. i saw also Motorola lapdock but i didnt think you can easily charge its battery by solar, but AA is easier to charge in emergency situations Oct 01 17:33:37 YOu can have up to four capes. Oct 01 17:34:10 However, cape compatibility is largely up to the user to determine. Oct 01 17:34:49 agmlego: thanks! thats clarifies. do you know where i can learn about least-power-consuming screens for BeagleBoard? i thought those touchscreen ones can use a lot of energy, i can be wrong Oct 01 17:36:06 Aytac_: I think the problem with the way you are coming abolut this is the "for Beaglebone" bit. Oct 01 17:36:47 Aytac_: Find any screen that accepts the outputs the bone can provide, and it will probably work fine. Power optimize among those choices. Oct 01 17:37:52 agmlego: thank you so much. i really appreciate it. these are enough explanations i think. best wishes! Oct 01 17:45:27 tbr: It's have to be more than 200 kSPS Oct 01 17:46:16 that's 1.6 MSPS. I'd guess that SPI can do that. Oct 01 17:48:59 I know that the BBB has 2 microprocessors (PRU), I would like to know if I can do the acquisition with than continually and do the processing with the main processor Oct 01 17:50:55 With the SPI I will have to stop the acquisition when treating the data. Oct 01 17:51:11 The PRUs can use SPI. Oct 01 17:52:25 I'm not sure if they would be strictly necessary. Oct 01 17:53:35 So yes for my question? The PRUs can read the 8ch ADC and write in the shared memory and the mains processor could read this shared memory in parallel? Oct 01 17:53:54 Sure. Oct 01 17:53:58 Why not? Oct 01 17:54:58 Dont know.. I'm new.. I'm stating to search about the PRUs and I dont know how to program than yet Oct 01 17:54:59 still not sure what the PRU would be necessary for Oct 01 17:55:29 * agmlego neither, but EddyUFCG seems to want to use it. Oct 01 17:55:36 To garantee the Real-time Oct 01 17:55:37 asynchronous capture and processing, perhaps Oct 01 17:56:40 EddyUFCG: you keep saying real time, but then your data ends up inside a linux system anyway Oct 01 17:57:19 And yes for asynchronous. I cant stop the acquisition when treating the data. Oct 01 17:57:35 or are you going to do more than passing it on to linux Oct 01 17:57:46 Real-time just for acquisition Oct 01 17:58:00 I don't see where you would need to _stop_ acquisition under linux. Oct 01 17:59:03 but if you want to use the PRU for the fun of it, nobody here will stop you Oct 01 17:59:53 Hahaha.. I dont want to use than if I can. Oct 01 18:01:12 I just dont know how to do the real-time acquisition and the parallel processing with main processor that runs linux Oct 01 18:09:47 EddyUFCG, is it possible you are trying to do something akin to this https://github.com/abhishek-kakkar/BeagleLogic/ Oct 01 18:12:01 Thank you. I will see it Oct 01 18:44:37 If i clone the eMMC of BBB_A to a SD card and then flash it to the eMMC of BBB_B do I need to do anything else to BBB_B to have an identical working copy of BBB_A? Oct 01 18:45:51 That's the way I do it, and it's worked just fine up to this point. Oct 01 18:46:50 I tried it today and I looks like it flashed alright but but I can't ssh, view the lighttpd webserver i have setup or mysql Oct 01 18:47:12 WHat does the serial output look like? Oct 01 18:47:56 I haven't checked the output but I can access the cloud9 ide and terminal that way Oct 01 18:48:31 I suggest logging into the machine and verify that the image that booted is in faxct the image you think you flashed. Oct 01 18:58:23 agmlego, thats the easiest way to check that? Oct 01 18:58:50 ...logging in over the serial console like usual, and checking to see that the changes you made on A are on B? Oct 01 18:59:19 I've fairly confident that its the same image because I can access the console via cloud9 and see that the new files are there Oct 01 19:02:16 Except that your services are not starting up in the configuration you expect. Oct 01 19:02:25 And thus, it is clearly not the same image. Oct 01 19:06:10 Hello Oct 01 19:06:41 Is it possible to debug kernel on beaglebone using KGDB? Oct 01 19:29:45 so my beaglebone rev C just stopping booting up -- PWR flashes for a split second when i press the power button, but nothing else, so i assume it's fried Oct 01 19:30:11 We assume you have looked a tthe boot output on the serial terminal. Oct 01 19:30:49 i uh.. haven't. i guess i will go learn how to do that and do that. Oct 01 19:31:30 Yup. ;-P Oct 01 19:32:12 Simple, though. Connect your FTDI adapter to the serial port pins, connect the USB end to your computer, and open a serial terminal program like screen or PuTTY. THen power the bone. Oct 01 19:32:49 thanks! i need to track down an ftdi adapter Oct 01 19:33:17 Yup. Oct 01 19:33:38 IIRC, the bone natively talks at 115200 8N1, but it might be 9600 8N1. Oct 01 19:33:45 The documentation says all this. Oct 01 19:36:48 115200 should work Oct 01 19:37:21 thanks guys. i think i have one of those at home actually since i think i needed it to hook up my arduino pro mini Oct 01 19:37:29 (or ladies) Oct 01 19:37:34 (or lady and guy) Oct 01 19:37:52 heh Oct 01 19:38:09 /whois generally tells a good story. Oct 01 19:38:39 indeed Oct 01 19:39:11 Has anyone had any success using Bittorrent Sync on the BBB. I see they have an arm version. Oct 01 19:41:36 kamileon: Not specifically, but I would suggest trying it out and seeing if it works. Oct 01 19:41:53 I see no reason in specific to the bone that would cause it to fail. Oct 01 19:44:05 Yea I was going to give it a try tonight when I get home. Thought I would ask first to see if anyone has had any headaches with it. Oct 01 19:45:26 kamileon: can i ask what the application is? use it as an always-on bittorrent sync server? Oct 01 19:48:10 Its a peer to peer file/folder sync. It allows you to access files and folders on any device. And it keeps it synced between all authorized devices. Oct 01 19:48:43 sorry, my question wasn't clear. i was just curious as to why you want to install bittorrent sync on the BBB Oct 01 19:49:02 Sorta of like a cloud service but without the cloud. It stores everything locally and just keeps it all synced together. Oct 01 19:49:51 Im using my bbb to caputer radio data with my rtl-sdr and want to be able to send the captured data to my home server. Oct 01 19:50:42 nice Oct 01 19:52:00 For me it seemed like the easiest way to do it. Oct 01 19:52:45 (netcat, ssh, scp, rsync, ftp) Oct 01 19:53:47 . Oct 01 19:54:48 But BTSync works OK too. Oct 01 19:56:28 I just figured BTSync was fast and easy to setup for testing purposes. Oct 01 19:57:28 Depends on what is on the other end processing the data. Oct 01 20:00:27 My home pc running Ubuntu 14.04 Oct 01 20:00:59 Yeah, but what is it doing with the data? Oct 01 20:01:22 Are you breaking the data up into regular chunks as files, or treating the stream as continuous? Oct 01 20:03:02 the stream from my BBB is continuous. My pc takes the sent data, decodes it and saves it in a text file Oct 01 20:03:24 So, you have the bone writing to the file while the pC reads from it? Oct 01 20:03:34 BTSync is probably the wrong way to do that then. Oct 01 20:04:21 yea Oct 01 20:05:07 I suggest using something more suitable to a stream of data, as opposed to individual files. Oct 01 20:06:24 alright, i'm going to head home and look for my serial to USB converter so i can hook it up and have my bone tell me its boned Oct 01 20:06:37 thanks for the help, "BB" later Oct 01 20:08:07 heh, boned Oct 01 20:09:30 so what would you suggest? Oct 01 20:13:37 kamileon: What software is at either end? Are you writing it, or is it prewritten? Oct 01 21:11:38 is the spidev api the only one provided for spi devices? Oct 01 21:11:43 it appears it only works as an spi master - is that true? Oct 01 21:11:48 i need to run my spi as a slave. Oct 01 21:13:20 spidev is the only one I have heard of on the bone, but that is not to say that a) you could not find some other api or b) simply write your own. Oct 01 21:22:22 spidev is for debugging only Oct 01 21:22:27 write a proper kernel driver Oct 01 21:33:01 ds2: got any hints/tutorials/examples/wild guesses? Oct 01 21:33:18 plenty of SPI drivers in the kernel tree Oct 01 21:33:31 for slave mode, you will have to write one using information from the TRM Oct 01 21:34:26 ds2: what is the "kernel tree" Oct 01 21:34:27 ? Oct 01 21:36:45 ds2: could you write such a driver as a kernel module, and simply modprobe it into a standard kernel prebuilt kernel? Oct 01 21:36:53 yates: The kernel tree is the kernel source code. Oct 01 21:37:00 I could Oct 01 21:37:18 but modules blow chunks so I prefer not to Oct 01 21:37:27 s/you/one/ Oct 01 21:37:43 why do modules blow chunks? Oct 01 21:37:48 agmlego: thanks. Oct 01 21:41:45 ds2: would you use the PRU in such a driver or just native ARM code? Oct 01 21:43:53 i guess ds2 likes throwing terms around to look smart without imparting any real knowledge... Oct 01 21:47:18 Or maybe ds2 is busy doing other things, and does not like hand-holding a person in a random IRC channel who feels it necessary to be snarky and rude to him after less than ten minutes' elapsed time. Oct 01 21:47:32 But yeah, probably the former, you are totally right, yates. Oct 01 21:49:04 one of the latter is certainly possible. Oct 01 21:50:12 i dare say learning how to write a kernel driver is hand-holding. it's not like asking how to configure my environment variables... Oct 01 21:51:15 agmlego: +1 Oct 01 22:33:44 yates: Sure, but things like "what is the kernel tree"... Oct 01 22:49:10 so my BBB seems to have have suddenly given up the ghost and i'm not able to see anything on the serial monitor when i try to boot Oct 01 22:49:26 i just get a brief flash of the PWR led when i press the button Oct 01 22:49:58 Interesting. Oct 01 22:50:15 So what changed between when it was working and when it was not? Oct 01 22:50:18 does it seem surprising that nothing shows on the serial monitor? Oct 01 22:50:33 it looks like the thing only shows activity for about a millisecond Oct 01 22:51:08 that's the weird thing, i had just successfully finished configuring it to use a usb wifi dongle Oct 01 22:51:22 The serial output will be from u-boot and the kernel. If the machine does not stay up long enough for u-boot to start... Oct 01 22:51:41 it only had the wifi dongle attached, and it was powered from a 5V 4A power supply from adafruit, nothing fancy Oct 01 22:51:57 i rebooted it to make sure it would auto-rejoin my network Oct 01 22:52:05 tested avahi by sshing using the hostname Oct 01 22:52:07 was pleased Oct 01 22:52:11 left for a half hour Oct 01 22:52:32 came back, reconnected a circuit i had been using successfully for the last week, and it wouldn't start Oct 01 22:52:40 disconnected the circuit, still no dice Oct 01 22:52:56 YOu powered it down before connecting the circuit? Oct 01 22:53:06 yep Oct 01 22:53:13 i have a fritzing diagram of the circuit -- it's pretty basic and there are no inputs at all, so i dont think i fried it with a high voltage input Oct 01 22:53:22 And were taking adequate ESD prevention measures? Oct 01 22:53:53 i believe so, but it's always a possibility Oct 01 22:54:07 Grounded mat, wrist strap to same? Oct 01 22:54:38 no Oct 01 22:55:06 not a staticky environment, but i wasn't wearing a strap Oct 01 22:55:10 Grounded wrist strap attached to one of the grounding vias on the mounting holes of the bone? Oct 01 22:55:13 Oh. Oct 01 22:55:23 Well, then we cannot rule out ESD. Oct 01 22:55:52 It does not take much--human beings can carry pretty significant charge and not feel it. Oct 01 22:56:20 i've been working on it without an issue in the same room for the past week, unplugging and replugging stuff in Oct 01 22:56:23 THis is why the bone ships in an ESD bag, and all the documentation is pretty loud about taking precautions. Oct 01 22:56:32 not ruling it out for sure Oct 01 22:56:37 markneub: And now your bone stopped working, so something changed. Oct 01 22:56:49 markneub: Past success does not indicate future performance. Oct 01 22:57:49 well, for lack of any other ideas about why it decided to stop working, i guess i'll just try again and be more careful about static Oct 01 22:58:13 do you know what's involved in the RMA process? i see there's a form to fill out Oct 01 22:58:34 but i'm curious as to what the turnaround time is, and whether there's a fee to have it repaired or whatever Oct 01 22:59:24 With boards this cheap I doubt there is repair service offered, and ESD damage is usually explicitly excluded from warranties on development boards. Oct 01 23:00:46 the support page indicates that there are repairs and replacements on unmodified boards offered by authorized resellers Oct 01 23:01:44 OK. Oct 01 23:45:22 dear all, I think I bricked my BBB, is there any sure way to make sure? Oct 01 23:46:47 serial console Oct 02 00:08:30 so? With the analog write what does changing the frequency do for you? Oct 02 00:09:38 my chip says it will do 100Hz-1Khz Oct 02 00:16:45 no, I would not use the PRU Oct 02 00:17:17 I have written code for a slave mode driver but that code was done for someone else and I cannot give it away. Oct 02 00:44:04 I hope writing yet another description of the pinmux won't cause a storm... :/ Oct 02 02:58:41 ds2: thanks for your responses. i certainly understand re: not giving away code. i was just looking for a little direction/guidance. **** ENDING LOGGING AT Thu Oct 02 03:00:00 2014
