**** BEGIN LOGGING AT Mon Apr 27 02:59:57 2020 Apr 27 03:00:15 Ha. Be careful. I am waiting for the influx of spam as we speak. Apr 27 03:00:39 I get some spam but not too often these days. I think the spammers are getting bored, i.e. if that is possible. Apr 27 03:01:09 Well if you have any questions or comments ou can e-mail my public address Apr 27 03:01:18 Oh. I got you. Okay. Apr 27 03:01:24 I will go to github to look. Apr 27 03:01:58 Here it is : ken.at.github@gmail.com Apr 27 03:02:21 Ut oh. Apr 27 03:02:34 Okay. I will send over an email one day. Apr 27 03:03:01 KenUnix: Just to say this out loud, this is being recorded and the logs are visable. Apr 27 03:03:19 So, you might receive some odd emails b/c of logging. Apr 27 03:03:43 I hope in the future to do more then bwbasic. That's OK it is a public address and I cn block spammers Apr 27 03:03:56 Oh. Okay. Apr 27 03:04:36 KenUnix: I know sometimes you split quickly. Apr 27 03:05:04 For whatever reason, you just leave. That is fine by me but I am left hanging in 'da breeze. Mate? Apr 27 03:05:13 Why do you leave so quickly around this time? Apr 27 03:05:16 e-mailing with RCN he suggested I can update online docs for the BBB to bring them more up to today Apr 27 03:05:24 Good idea. Apr 27 03:05:35 I can help you if necessary. Apr 27 03:05:42 Docs need updating. Apr 27 03:06:03 On elinx? Apr 27 03:06:10 Sorry. On elinux? Apr 27 03:06:16 Well you need to register which Apr 27 03:06:26 Oh. Apr 27 03:06:27 I did and am waiting Apr 27 03:06:31 Good luck. Apr 27 03:06:38 That is a big agenda to take on. Apr 27 03:06:55 Even updating the updates is hard. Apr 27 03:07:26 Then, trying to find out what updates work compared to prioritizing what has not worked in so long is another idea. Apr 27 03:07:28 But yep. Apr 27 03:07:29 Already took care of somr sites gone or discontinued serial adapers Apr 27 03:07:35 Good luck. Apr 27 03:07:36 Oh. Apr 27 03:07:38 Nice. Apr 27 03:07:56 They went out of biz? Apr 27 03:08:11 Oh. I got you. Apr 27 03:08:20 Yes tilde Apr 27 03:08:30 `? Apr 27 03:09:05 If you see any wrong info please e-mail me and let me know Apr 27 03:09:10 What? Apr 27 03:09:13 Serious? Apr 27 03:09:17 Okay. Fine. Apr 27 03:09:23 why not Apr 27 03:09:24 Where would I see bad info? Apr 27 03:09:40 Like online at elinux or other sites or just in general? Apr 27 03:10:01 I think I need a list first. Then, I can read over what has happened. Apr 27 03:10:03 for examples in BB online docs that point to bad addresses Apr 27 03:10:09 Oh. Apr 27 03:10:17 Got it. I have found many of those. Apr 27 03:10:44 I would like to fix or remove Apr 27 03:10:57 Okay. Are you handy w/ js? Apr 27 03:11:18 no jerk script sorry Apr 27 03:11:31 Oh. I thought the site was comprised of js. Apr 27 03:12:01 the one i passed also has a lot of 'c' code Apr 27 03:12:33 Okay. Apr 27 03:12:40 Let me send over a test e-mail. Apr 27 03:13:02 I will test the email address as seth@______.com. Apr 27 03:14:43 Did you get it? Apr 27 03:16:02 By the way that site some of the 'c' examples don't compile they need TLC. Wait i'll check Apr 27 03:17:05 Got it : Here is the test email I told you I would make quickly. Apr 27 03:17:15 So, on the site (the current site @ bbb.io), and let me get this right, you want me to check current site status on specific pages and make sure the "go-to" site is available still? Apr 27 03:17:19 Right... Apr 27 03:17:21 That was me. Apr 27 03:18:28 and then report the findings in an easy to view manner? Apr 27 03:18:56 No, the docs pages for the BB on elinux Apr 27 03:19:27 What ever RCN has a hand in Apr 27 03:21:01 Oh. Okay. Apr 27 03:21:15 I just went to bbb.io/videos and the videos are not loading. Apr 27 03:22:28 Whats the full URL? Apr 27 03:22:34 I will try on elinux. Is there a start page you have in mind. This way, I can just scroll to specific sites available from that start page. Apr 27 03:22:37 Oh. Apr 27 03:22:39 Please hold. Apr 27 03:23:05 this one: https://beagleboard.org/Videos Apr 27 03:24:35 KenUnix: Are you about to leave? Apr 27 03:24:50 If so, I will see you another day. If not, I will brb Apr 27 03:24:51 I ear marked it will look tomorrow Apr 27 03:24:56 Okay. Apr 27 03:25:02 Yep eyes shot bed time Apr 27 03:25:05 Okay. Apr 27 03:25:08 Later mate. Apr 27 04:56:09 hi Apr 27 04:56:23 anybody out there? Apr 27 04:59:15 nope .. nobody is here. Not a soul. Or even a vampire. Apr 27 04:59:53 ;) Apr 27 11:59:10 m Apr 27 12:50:21 dear all, can help me to provide me a reference document which has steps to compile uboot and linux kernel ? Apr 27 17:34:15 ankur: can you check https://www.digikey.com/eewiki/display/linuxonarm/BeagleBone+Black and see if it helps? Apr 27 17:39:43 hi Apr 27 17:40:08 can you help me ? Apr 27 17:40:29 luna: the theme here is "just ask, be patient", don't ask to ask. Apr 27 17:40:55 noone can help you as long as you haven't explained what it is you need help with Apr 27 17:43:38 the BeagleboneBlack send this data : [32, 11, 110, 22, 220] via SPI ... but the output is [0,0,0,0,0] Apr 27 17:44:09 luna: start with what you are trying to do. Apr 27 17:44:30 Then, say what you've done, what you expected and then what happened. Apr 27 17:45:05 If I were to zip straight to a totally uninformed guess, you probably didn't set the pinmux. Apr 27 17:45:35 in general, if you're not seeing data on the pins where you were expecting them, double-check you're using the right spi device, that you're checking the right pins, and like jkridner[m] just said that pinmux has been correctly set up Apr 27 17:46:07 luna: are you the one contacting BeagleBoard on Facebook? Apr 27 17:48:05 jkridner : yes Apr 27 17:48:27 I am trying to connect a BBB to a microcontroller via SPI, Apr 27 17:49:49 i have the last version Debian , Apr 27 17:50:09 Check the pins and the pinmux configuration. Apr 27 17:50:26 i tryed to send data from BBB to logic analyses Apr 27 17:50:48 one way to verify your pinmux is correct is using my show-pins utility: https://github.com/mvduin/bbb-pin-utils/#show-pins Apr 27 17:53:07 i try with Adafruit Library with SPI0 . pin17 , pin18 , pin21 ,pin22 Apr 27 17:54:00 if i press run in cloud9 .. it give me this output [0, 0, 0, 0, 0] Apr 27 17:57:18 zmatt : thanks i would like to read it , Apr 27 17:58:37 zmatt : "check you're using the right spi device," how can i check it ? Apr 27 17:58:43 I wouldn't be surprised if the adafruit library is to blame. I suggest just setting up pinmux explicitly (either by using the config-pin utility or by using these tiny python library: https://pastebin.com/MKtWJ8G8 ) and then using the python "spidev" library, which unfortunately doesn't seem to be installed by default. if your bbb has internet access (e.g. via Ethernet) then you can install it using ... Apr 27 17:58:49 ..."pip3 install spidev" Apr 27 18:03:32 if your bbb doesn't have internet access, here's the alternative way to install it: https://pastebin.com/Dc7Bk8UD Apr 27 18:06:13 zmatt : my bbb has internet , i installed it already , do you have a Example with spidev library ? Apr 27 18:08:59 hold on Apr 27 18:16:31 untested example: https://pastebin.com/kNcsChRF Apr 27 18:19:41 I don't know if my message got through before my connection died so I'll just repeat what I said: Apr 27 18:19:45 untested example: https://pastebin.com/kNcsChRF Apr 27 18:19:48 instead of using the little bone_pinmux library you can also use the config-pin utility prior to using the port, or use an overlay to set it up. but this is probably the simplest way for experimenting Apr 27 18:21:16 (the one thing I really don't like about the python spidev library is that you can't specify the device by path, which prevents using symlinks created by udev) Apr 27 18:39:38 zmatt finally got all the libs installed for the usb to web server thing on the BBB. However, I'm getting VIDOIC_QBUF: Invalid Arguement. I followed this here and I'm using his source (it works on Windows no problem) Apr 27 18:39:39 https://www.pyimagesearch.com/2019/09/02/opencv-stream-video-to-web-browser-html-page/ Apr 27 18:39:40 Ideas? Apr 27 18:43:15 dunno, streaming video from a usb webcam on a beaglebone sounds like a masochistic exercise to me Apr 27 18:43:54 I'm super close. The program runs now (after stumbling over tons of lib installs). Google says something about UV4L issue, but I can't seem to find the repo for Buster to try to reinstall Apr 27 18:44:59 Also it's a VIDIOC_QBUF: Invalid argument, I think I mistyped the first part Apr 27 18:45:51 But you are right...it's a severe headache. Apr 27 18:45:59 uv4l ? why are you using that? o.O Apr 27 18:46:15 That's what Google said may be causing the issue I'm having Apr 27 18:46:28 why would you be using it in the first place? Apr 27 18:46:41 instead of just the normal v4l2 api that opencv uses by default Apr 27 18:46:41 To be 100% honest, I'm not totally sure what it is yet. Apr 27 18:46:56 I linked the exact code I'm running to do this with Apr 27 18:47:06 https://www.pyimagesearch.com/2019/09/02/opencv-stream-video-to-web-browser-html-page/ Apr 27 18:47:35 I don't see any mentions of it, it was just the hole I was going down to try to fix Apr 27 18:47:46 I was about to say, I see no mention of uv4l Apr 27 18:48:13 That's just how Google said to start looking. I'm so burned out on this...but have to get it going XD Apr 27 18:48:18 and there's no debian package for it (in debian's own repos anyway), which also implies it's not used as a dependency by the opencv libs which do have debian packages Apr 27 18:48:31 Yea; this is OpenCV Apr 27 18:48:54 so I see no reason to think uv4l is relevant Apr 27 18:49:12 Yup; I just don't know where to go from here then. Apr 27 18:49:42 It's spinning up the web server too, so it has to be somethign with accessing the usb Apr 27 18:50:07 I mean yeah, clearly something is going wrong with the video capture Apr 27 18:50:18 wonder if i need sudo? Apr 27 18:50:22 you don't Apr 27 18:50:26 this is not a permission error Apr 27 18:50:47 have you tested the same webcam on some other linux system? Apr 27 18:51:36 sorry, got booted for a sec Apr 27 18:51:45 every once in a while I get this too ImportError: /usr/local/lib/python3.7/dist-packages/cv2/cv2.cpython-37m-arm-linux-gnueabihf.so: undefined symbol: __atomic_fetch_add_8 Apr 27 18:52:16 I'm just about to say switch to Windoze Apr 27 18:52:22 Hi Apr 27 18:52:41 I have issue with setting up SPI on the latest buster image Apr 27 18:53:12 I actually only get the atomic fetch error when i run sudo Apr 27 18:53:15 that's weird Apr 27 18:53:17 can anyone point out solution for SPI setup? Apr 27 18:53:25 Thanks in advance Apr 27 18:53:26 Guest14802: what programming language? Apr 27 18:53:37 Python SPI Apr 27 18:53:46 but SPI has to enabled first Apr 27 18:55:05 anyone availalbe now? Apr 27 18:55:27 Guest14802: have patience, it can take time for someone to respond Apr 27 18:55:40 ok thanks Apr 27 18:56:10 I think there may be some issue with the adafruit spi library on the latest image. you can try this (untested) example that uses the spidev library: https://pastebin.com/kNcsChRF Apr 27 18:57:04 (install with pip3 install spidev if your beaglebone has internet access, or use these instructions https://pastebin.com/Dc7Bk8UD if it doesn't) Apr 27 18:59:05 jkridner: while I approve that the bogus spidev numbering has been fixed in the latest image, it's annoying that this has been done without ensuring that common ways to use spi (like the adafruit library) actually still work. creating the symlinks in /dev/spi/ doesn't automagically ensure people use it Apr 27 19:02:25 zmatt: do you think the issue is with this line? vs = VideoStream(src=0).start() Apr 27 19:02:28 I'm starting to wonder Apr 27 19:04:01 biggi_: I have no thoughts on this issue, other than wondering whether it might not be simply caused by the crappy usb driver or the poor performance Apr 27 19:04:24 I'd expect it to at least open the camera up Apr 27 19:04:29 I think he did it on an RPi Apr 27 19:04:35 So I'm wondering what could be the difference. Apr 27 19:04:37 I guess Apr 27 19:04:47 I mean, the rpi is not the same as a beaglebone Apr 27 19:05:53 I don't disagree. However, I'd think they'd be close enough going USB and since Raspbian is based off Debian Apr 27 19:06:33 I'm pretty sure some of the driver problems and the performance problems deriving from that are specific to the AM335x Apr 27 19:07:18 (and some are probably fixable if someone with enough knowledge cared enough to sink some time into them) Apr 27 19:07:42 but I generally just avoid using usb :) Apr 27 19:07:49 I just wonder if it's not initializing the camera right. Apr 27 19:07:56 perhaps Apr 27 19:08:06 Which brings me back to that line XD Apr 27 19:08:26 I have basically zero experience with v4l2 and absolutely zero with opencv, so I'm afraid I won't be very helpful with this Apr 27 19:08:47 It's no problem :D Apr 27 19:08:55 I'll get it figured out, it's just a pain in the rear Apr 27 19:09:16 i am trying to check if spi works with spidev_test.c Apr 27 19:09:32 which retruns spi mode: 0bits per word: 8max speed: 500000 Hz (500 KHz)00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 Apr 27 19:09:55 I have put a jumper on p9_18 and p9_21 Apr 27 19:10:49 biggi_: I have done some stuff w/ opencv adn v4l2 (sort of). Apr 27 19:10:58 But just for video stuff. Apr 27 19:11:18 Not for using it for calculating movement or understanding colors. Apr 27 19:11:35 set: I'm using this exact code to just stream to a web server https://www.pyimagesearch.com/2019/09/02/opencv-stream-video-to-web-browser-html-page/ Apr 27 19:11:49 getting error VIDIOC_QBUF: Invalid argument Apr 27 19:12:12 seems like it throws the error everytime it's trying to take a frame, so I'm feeling it's in the camera init Apr 27 19:13:20 Oh. I think that page is not collective. I signed up to get info. from that business man a while back and... Apr 27 19:13:30 W/out the book or the source, it is a waste of time. Apr 27 19:13:38 he has the source there Apr 27 19:13:49 i think you have to enter email and it'll send it to you to download Apr 27 19:14:40 Because I run that on Windows and it's no issues at all. Just can't get it to run on the BBB. Haven't tried it on my laptop running Debian yet either though. Apr 27 19:14:57 Right. I tried it before. I am not downing that person or anything. It just seems like the person learned a lot in that dept. and the book is what he was trying to sell instead of just the open source library. Apr 27 19:15:16 biggi_: Let me show another library. Apr 27 19:15:29 Gotcha. I'm open to whatever. I just want to try to stream from the USB camera to a web server thing. Apr 27 19:16:00 https://github.com/jacksonliam/mjpg-streamer has helped me stream from a WiFi bot to a web server online. Apr 27 19:16:23 on BBB? Apr 27 19:16:42 It is easy to set up w/ make and sudo make install. YOu can use opencv w/ it and other ideas. Apr 27 19:16:44 yes. Apr 27 19:16:52 On the BBB. Apr 27 19:17:13 Well. BBBW. Apr 27 19:17:14 Sorry. Apr 27 19:17:14 do you have a git/gist of the source you used to stream it? Apr 27 19:17:25 If you dont mind sharing, it might help. If you do mind, I totally get it :D Apr 27 19:17:34 No. But, I am willing to look it up. Apr 27 19:17:38 Please hold. Apr 27 19:17:48 No problem; and I thank you! Apr 27 19:19:34 https://pastebin.com/pw2WNa2p shows the simple command you can try from the command line. Apr 27 19:20:15 So, just git clone the repo, get into the directory it states you need to be in, and then make and sudo make install. Apr 27 19:20:27 does that run from local host? Apr 27 19:21:12 No. It runs from your ip address. You might have to set up local configs. for it to work like that. Apr 27 19:21:58 I'll give it a shot. Getting cmake and what not installed Apr 27 19:22:29 So, instead of beaglebone.localhost or whatever, you would run it from 192.168.7.2: and/or 192.168.13.145:. Apr 27 19:22:44 You do not need cmake. Apr 27 19:22:58 you only need make and sudo make install to get all libraries. Apr 27 19:23:17 but cmake can help if you plan on disabling specific parts to that library. Apr 27 19:23:27 gotcha. trying to find best way to clone the git repo into the directory too. i haven't done anything like this in linux XD Apr 27 19:23:32 I'm a windows boy Apr 27 19:23:42 git clone ...... Apr 27 19:24:00 lol Apr 27 19:24:12 that's the best way yup Apr 27 19:24:18 I'm big dumb on this stuff Apr 27 19:24:25 Learning as I go Apr 27 19:24:27 git clone the_repo_github_site Apr 27 19:24:32 yup that's done Apr 27 19:24:34 Okay. Apr 27 19:25:13 Oh. You will need a couple libraries too. Apr 27 19:26:05 doing the make now Apr 27 19:26:18 I'm following the instructions he has on that github Apr 27 19:26:25 Hopefullyt hose are right? Apr 27 19:26:40 The repo states libjpeg8-dev but you will need 64 and not 8. 8 is no longer available. Apr 27 19:26:48 Yup; already figured that out Apr 27 19:26:51 Okay. Apr 27 19:27:50 There are errors to read over at times but the errors show what to install if you have missed any installs on your machine. Apr 27 19:28:11 so i did the make and then make install and then ran your command and I'm getting address already in use Apr 27 19:28:20 Right. Apr 27 19:28:20 and inappropriate ioctl for device Apr 27 19:28:24 Right. Apr 27 19:28:41 That is b/c of port :8080 already being in use. Apr 27 19:28:50 right Apr 27 19:29:01 The port is being used by nginx Apr 27 19:29:14 So, you will have to go to the nginx directory. Apr 27 19:29:32 Then, change nginx's port 8080 to another port. Apr 27 19:31:01 so, sudo nano (or your favorite editor) /etc/nginx/sites-available/default Apr 27 19:31:36 Then, change the default server if you want to use the opencv and the newly used repo. for web servers and video. Apr 27 19:31:48 That is one way. Apr 27 19:31:55 right, i changed 8080 to 8081 Apr 27 19:32:02 Okay. What happened? Apr 27 19:32:13 then went to relaunch the program and still get 8080 in use. Apr 27 19:32:16 wonder if i need to reboot Apr 27 19:32:18 Did you restart nginx yet? Apr 27 19:32:31 Let me go and see the command for nginx. Apr 27 19:32:33 no, i was going to ful reboot Apr 27 19:32:50 Oh. Okay. That will help too but I suggest restarting nginx. Apr 27 19:32:58 sudo systemctl restart nginx Apr 27 19:33:11 alright so now looks like I'm ok Apr 27 19:33:14 Right. Apr 27 19:33:19 Okay. Apr 27 19:33:25 It works? Apr 27 19:33:28 no errors except for saying pan/tilt is an inappropriate ioctl, but i don't care about those Apr 27 19:33:29 i think? Apr 27 19:33:34 need to check to see if I can get the stream Apr 27 19:33:39 Right. Apr 27 19:34:43 It works...but the camera is wonky. It's like 1/4 of the left is on the right side Apr 27 19:34:50 What/ Apr 27 19:34:51 ? Apr 27 19:34:52 Odd. Apr 27 19:35:03 What camera are you using? Apr 27 19:35:15 brio Apr 27 19:35:37 I have a MS HD-3000 and it works like a charm and w/ the new image from BBB.io/latest-images, it works well. Apr 27 19:35:46 brio? Apr 27 19:35:53 Logitech Brio Apr 27 19:35:55 I never heard of one. I will go and look it up. Apr 27 19:35:56 Oh. Apr 27 19:36:08 Wonder if this is the performance. It can't write the images. Apr 27 19:37:21 YOu can go to fps at 50 and change to 720p for seeing if that helps. Apr 27 19:37:35 But, those are camera effect issues. That might be of use. Apr 27 19:37:42 https://imgur.com/OUSRBAo Apr 27 19:37:57 It's running 640x480 atm Apr 27 19:38:07 FPS is set to -1? Apr 27 19:38:44 Okay. I am not sure what that means just yet. Oh and that imgur site is not functioning on my end. Let me try to erase my cache. Apr 27 19:39:38 OH. Apr 27 19:39:59 Do you have your BBB plugged in via USB and Barrel Jack? Apr 27 19:40:15 No, just USB on a 3A plug Apr 27 19:40:40 Oh. Apr 27 19:40:45 Try Barrel Jack. Apr 27 19:40:58 Do you have a barrel jack? Apr 27 19:41:08 w/ 5v 1A supply? Apr 27 19:41:11 Small problem with that is I dont' have one here and I currently can't even go into work XD Apr 27 19:41:35 Ideally, we're going to run this PoE splitter to USB anyways. Is the USB input limited to 500mA on this? Apr 27 19:41:56 Got it. Okay. On my BBBW and BBG and BBGW, they need extra mA supplied to support usb webcams. Apr 27 19:42:00 They are power hungry. Apr 27 19:42:08 So it needs both? Apr 27 19:42:17 A 3A USB isn't enough? Apr 27 19:42:37 Just like WiFi adapters. Well, not really. They can use 5v only from the wall adapter or battery source. Apr 27 19:43:16 I think things are set up to work in a particular manner. Apr 27 19:43:22 For instance... Apr 27 19:44:12 I had a BBGW and it worked. It worked so well so that I had to make it into a bot. This bot needed 12v Battery for the Cape and to power the BBGW. But... Apr 27 19:44:40 The extra mA needed was supplied via the Micro USB onboard the BBGW for use w/ a WiFi webcam. Apr 27 19:45:57 Gotcha. I'll order one today and have it here tomorrow to test. I think for now I'm ok, but we will be doing other things on here as well instead of just processing camera. Apr 27 19:46:01 So now I'm a tad worried. Apr 27 19:46:04 biggi_: I am not sure if it is safe to run 3A into the BBB alone just w/ a webcam. I know people use 5v 1A if no Cape is attached via the barrel jack. I am not sure about usb at 5v 3A. Apr 27 19:46:19 Worried? Apr 27 19:46:20 3A is just the supply it can pull, not what's being supplied at all times. Apr 27 19:46:37 Worried as in I think I may be trying to do too much on one board. Apr 27 19:46:45 Okay. I read on the SRM that 1A at 5v was good for it. Apr 27 19:46:47 I'm still going to be also working with some motor drivers/encoders Apr 27 19:46:58 Okay. Nice! Apr 27 19:47:06 Which ones? Apr 27 19:47:18 There are unlimited as I can tell. Apr 27 19:47:22 So I'm worried if I'm needing extra current at this point that I'm going to not be able to use them all on one board. Apr 27 19:47:23 Which what? Apr 27 19:47:34 motor drivers? Apr 27 19:47:42 Oh. The BBB can handle it. Apr 27 19:48:40 Something like these https://www.omc-stepperonline.com/digital-stepper-driver/digital-stepper-drive-10-32a-18-30vdc-for-nema-17-23-stepper-motor-dm332t.html Apr 27 19:48:46 I know people say this and that but I have had a 12v 1.3A battery on the BBBW w/ MotorCape plugged in and another battery in the barrel jack. Apr 27 19:49:23 Oh. Apr 27 19:49:45 Yea. I have two of those, well, in a different package. Let me see. Apr 27 19:50:27 Yep. I have a generic one. Oops. Apr 27 19:50:36 9 to 42V. Apr 27 19:51:12 But... Apr 27 19:51:31 Like the MotorCape, there are specific parts that need to be used to make sure the BBB is safe. Apr 27 19:51:49 The MotorCape uses L298 drivers. Apr 27 19:52:02 There are a ton of ideas relative to the L298 drivers. Apr 27 19:52:15 I'm just going to use the PWM output to a transistor set to drive the driver Apr 27 19:52:22 So, it uses onboard the PWM signals and GPIO. Apr 27 19:52:23 Okay. Apr 27 19:54:04 Anyway, if you need anymore ideas for opencv, look here at this short article I tried out: https://www.hackster.io/functt/recording-and-usb-web-cameras-with-the-bbai-and-opencv-d8d68d. It is for recording w/ opencv. Apr 27 19:54:41 Thanks! gotta run, skype meeting, thanks again for the help! I'll see what happens after I get extra power. Apr 27 19:55:21 Okay. Later. Apr 27 19:55:42 Thank you so much again, hopefully the extra power gets it going Apr 27 23:56:44 If the correct PHY is placed on the AM3358 it can do 1G ethernet? Apr 27 23:57:06 I guess I didn' Apr 27 23:57:20 t realize that since the BBB comes with 10/100 PHY Apr 27 23:58:52 correct, it can even have two gigabit ports Apr 27 23:58:52 just like the am572x Apr 28 00:01:10 yet another thing that states blatantly RTFM on it. Apr 28 00:09:00 Does the fritzing part for the BBAI work on your end? Apr 28 00:11:04 I am asking b/c the part says it is already loaded to fritzing on my end when I try to "import" it into my "bin." Apr 28 00:18:32 If this means anything to anyone, this is the part number that keeps coming up 'prefix0000_54b7cd94fdd33f8e98c7b4d8_2' Apr 28 01:07:38 Do not worry about it. It is miraculously working for some reason. Apr 28 01:16:43 Did anyone ever make a Cape Fritzing before? Apr 28 01:20:18 Outside of BELA? Apr 28 01:35:14 Hi guys Apr 28 01:35:50 set_ you gave me quite the project with those capes. Apr 28 01:36:16 Found one 4 motors or 6 servos... Apr 28 01:39:21 Ha. Apr 28 01:39:32 Discontinued was most of 'em. Apr 28 01:39:50 even from OnLogic. Apr 28 01:40:35 KenUnix: Do you mess w/ Fritzing at all? I am asking b/c I want to make some Fritzing diagrams and although I have been a user of fritzing before, I never really used their nuts and bolts to produce anything. Apr 28 01:43:01 "Produce anything" in this context basically means the GHI Capes or the Seeed Studio Cape for making alternate diagrams. Apr 28 01:43:33 https://www.seeedstudio.com/Motor-Bridge-Cape.html Apr 28 01:44:26 The one I sent you and the one regarding online capes Apr 28 01:47:40 Okay. Apr 28 01:47:42 I can't find the link to "BeagleBone Community" you sent me Apr 28 01:48:04 Oh? Apr 28 01:48:09 Let me go and look. Apr 28 01:52:56 https://pastebin.com/11NXVaNM Apr 28 01:56:47 The Go To Community Wiki Page is a large orange radio button on the right side of the screen. Apr 28 01:57:38 I did not complete it yet and the Official Wiki Page has not been touched by me (yet). Apr 28 02:02:18 OK great. After all that work on the video page now their not interested. WTF? Apr 28 02:02:26 Ha. Apr 28 02:02:28 Okay. Apr 28 02:02:39 Odd days. Apr 28 02:02:50 I guess people do not want to have things changed just yet. Apr 28 02:02:55 I like it.. Brought up to date Apr 28 02:03:03 That is all. Apr 28 02:03:41 I'm still working on the other one. That spreadsheet Apr 28 02:04:03 Oh? So, it is off or you want to keep trying w/ the eLinux.org site? Apr 28 02:04:16 I cleaned up and marked all the dead one or sold out ones ouy want it back in Excel format? Apr 28 02:05:00 no, not me. Apr 28 02:05:04 I'll keep tring who is Jason? Apr 28 02:05:20 One of the original founders. Apr 28 02:05:26 The spread sheet you ssent me Apr 28 02:05:46 RCN said to talk to him Apr 28 02:05:54 Wait? I did not send a spread sheet. Apr 28 02:06:10 I sent that messed up article for testing. Apr 28 02:06:14 It was a .docx file. Apr 28 02:07:02 No the attachment on capes new or under developement Apr 28 02:07:08 testy article? Apr 28 02:07:11 Oh. Apr 28 02:07:30 Yes GenTooMan, testy articles on my end. Apr 28 02:08:10 If you guys are interested I will uplead the fixed video html. set_ already tried it Apr 28 02:08:18 It works! Apr 28 02:08:54 I also found a bunch of old info. that no one looks over any longer (I am guessing). Apr 28 02:09:04 * GenTooMan officially declares he's a blind deaf mutt and thus has nothing to see hear or say for that matter. :D Apr 28 02:09:13 Just download it and call it xxxx.html and open it in your browser wait Apr 28 02:09:43 GenTooMan: Are you upset at something? Apr 28 02:09:52 If the info is moldy and oldy people give up Apr 28 02:10:01 Just attempting to be humorous. Apr 28 02:10:12 GenTooMan: It works! Apr 28 02:10:42 Some people are traditionalists while others are progressive. Apr 28 02:10:49 It really depends. Apr 28 02:11:16 Some people want things to not work b/c it has worked so well. Apr 28 02:13:12 Heres that html gentooman https://pastebin.com/PcVhgzBF Apr 28 02:13:40 What did my dear grandpa used to day, "If it ain't broke, don't fix _____." Apr 28 02:14:01 day = say, dang it. I thought I had it down pat. Apr 28 02:14:27 well their is a good reason for things. For example ever wonder why a car has a steering wheel and not a joystick or something else? Apr 28 02:16:06 Try that link again it was locked Apr 28 02:18:37 looks to be a hide text mangled library :D Apr 28 02:18:50 Oh I mean an HTML file? Apr 28 02:19:45 Hey. I once say a square steering wheel. Apr 28 02:20:22 you mean you saw right? Also is the beagle bone blue a black derivative? Apr 28 02:20:41 I saw it! I did not drive it. Right. Apr 28 02:20:57 The Blue? A black derivative? Hmm. Apr 28 02:21:01 Yes! Apr 28 02:21:19 Well, it has the am335x on it. Apr 28 02:21:34 Look at the html one of the videos not tell you the differences between them Apr 28 02:21:39 Instead of SoC, it is a SiP. Similar but different. Apr 28 02:22:00 shouldn't it be heirarchically catagorized under it? If it doesn't have the same headers then it's not the same. Apr 28 02:22:23 By way of headers, yes. I see it. I see the difference. Apr 28 02:22:30 But, programmatically, it is similar. Apr 28 02:22:46 The am335x is still around! Apr 28 02:22:46 the pocket beagle isn't a beagle bone black derivative whereas a beaglebone green from seeed is. Apr 28 02:23:19 yeah the pocketbeagle doesn't really have anything in common with the beaglebone other than both being am335x-based Apr 28 02:23:33 Yep. Apr 28 02:24:09 The am335x makes it similar but it is different b/c it is a real soldering joy for those who love to solder and apply their own workings. Apr 28 02:25:11 Was reading an article re PBB and adding a USB port to it Apr 28 02:26:01 That video along with the comparision video got dropped from html file Apr 28 02:26:43 GenTooMan: I just received some nifty info. on the Dynamixel Servo. Apr 28 02:26:57 I just like being sure I know what I'm looking at. I have 2 beagleboards ... not that I used them for anything more than projecting a low rez movie on my wall a bunch of times. I had to use an Apple USB network toy. Apr 28 02:27:03 RCN said don't add just update. i said it was a disaster Apr 28 02:27:30 The fellow gave out a nice schematic for working w/ 3.3v logic and their servos. Apr 28 02:27:43 Wait. I will show you. Apr 28 02:27:45 ahh that might be useful. Apr 28 02:27:55 it is not like the garbage they have on their site. Apr 28 02:28:01 It is actually useful. Apr 28 02:28:42 Why do they have sub par information on their site afraid people will use their servos for something? :D Apr 28 02:29:05 Oh the other file references WiFi adapters that don't work. just ask me. Apr 28 02:29:07 Probably. Like making neat things. Apr 28 02:30:01 https://community.robotsource.org/t/re-half-duplex-uart-for-ttl-commincation-and-wiring-w-the-hc126-and-hc04/1844/7 is for 3.3v logic that might happen on my end. But... Apr 28 02:30:18 I do not want to destroy my board just yet by accident. Apr 28 02:30:25 I wonder if TI has any schematics on how to add a 1G PHY to the AM3358 ... I don't seem to be able to find much. Apr 28 02:31:57 Hmm. I definitely do not know. Apr 28 02:32:00 GenTooMan: I mean, you just look up the rgmii pins and hook it up... there's really not much to it Apr 28 02:32:13 or look at the BeagleBone Enhanced as example Apr 28 02:32:15 So what is the HC126 some kind of fancy op-amp? Apr 28 02:33:01 GenTooMan: see also section 14.2.7 of the AM335x TRM Apr 28 02:33:25 HC126...it is a quad-buffer/line driver. Apr 28 02:33:38 It has three outputs. Apr 28 02:34:01 Oh. Cause it's diagram look like an op-amp Apr 28 02:34:46 KenUnix: Are we still embarking on this journey? Apr 28 02:34:47 zmatt hmm right I was looking at the schematic for the starter kit because it has 2 1G ethernet ports.. OK I was trying to see if I missed something. I guess look at the TRM to be sure. Apr 28 02:35:17 set_ you mean it has tristate outputs? Apr 28 02:35:46 Maybe not for bbb.io but for the eLinux.org pages. It may be helpful to new people looking to use the board. Apr 28 02:35:58 tristate outputs. yes. Apr 28 02:36:18 the Board! Boards! Apr 28 02:37:15 Journey? Apr 28 02:37:33 the hc126 is an inverting control tristate buffer. So you can drive the input and disable the output. It has 4 such circuits to allow you to make different buffer arrangements. The HC125 is it's compliment and has a non inverting control input. Apr 28 02:38:25 GenTooMan: https://pastebin.com/raw/KVQUkuaG Apr 28 02:38:40 Tristate like NJ NY a,d PA. Sorry couldn't resist Apr 28 02:38:58 Or qaud like four-corners. Apr 28 02:39:42 better known as TexArKanana. Apr 28 02:40:04 set_ Journey? Apr 28 02:40:30 TexArKanana oh here comes the bandit Apr 28 02:41:33 KenUnix: Yes. Journey. Apr 28 02:41:48 GenTooMan: note however that the am335x does not support RGMII internal delay, so either internal delay must be enabled in the phy (and if support for ethernet boot is desired then it needs to have it enabled by default) or you somehow need to insert sufficient delay in the pcb trace itself Apr 28 02:42:00 Were are we goin to Florida? Apr 28 02:42:18 KenUnix: Are we still planning on me relaying info. to you for the change up of the eLinux.org pages? Apr 28 02:42:32 You know. Basics and such. Apr 28 02:42:43 zmatt thanks ... I'll have a look at it. Apr 28 02:42:44 Sure Apr 28 02:42:49 Okay. Apr 28 02:42:58 I am all in. I will deal w/ it still. Apr 28 02:43:29 I get bored not making source. So, this will give me a venture to direct attention towards when I am not reading. Apr 28 02:43:31 GenTooMan: iirc ds2 once patched a gigabit phy onto a BBB Apr 28 02:43:56 zmatt That would explain the fore knowledge. :D Apr 28 02:51:56 GenTooMan: this explains the delay issue quite nicely: https://ethernetfmc.com/rgmii-interface-timing-considerations/ Apr 28 02:52:43 the AM335x does not support internal delay for the tx clk nor for the rx clk Apr 28 02:54:50 right sounds like I have to find the correct PHY or do some work on the PCB. Apr 28 02:59:57 thanks zmatt **** ENDING LOGGING AT Tue Apr 28 02:59:59 2020
