**** BEGIN LOGGING AT Mon Oct 02 03:00:01 2017 Oct 02 03:48:45 ... Oct 02 03:49:05 I am starting out new with a fresh image. I will keep this chat updated. Oct 02 09:52:42 Hi People Oct 02 10:40:25 'allo Oct 02 11:01:28 Hi guys. I have a requirement. I want to access BBB from internet just like Teamviewer but i dont want to forward my BBB's IP on router and also no desktop sharing. Only ssh stuff. Is it possible?? I am looking into the matter and most options are related to vnc and x11 stuff. any leads to proper direction or where i should look into. Thanks Oct 02 11:02:32 maheen: you can look into yaler Oct 02 11:03:08 maheen: given the description, you will always need some external relay service. Oct 02 11:04:04 yaler is a third party just like teamviewer minus desktop sharing? Oct 02 11:04:48 yaler is a lot simpler Oct 02 11:05:20 Hello Oct 02 11:06:36 The wireless LED on beaglebone black wireless is not glow. Can anybody help to fix it ? Oct 02 11:07:17 I am using debian 9.1 latest image Oct 02 11:58:12 Give it time. How long has it been since it was plugged in? Oct 02 13:14:55 I will be back. Mark my words. See 'ya later, gator. Oct 02 13:59:14 Does anyone have an Eagle library for the USB Type A Host port on the BBB? Oct 02 15:21:59 Hi all, I'm currently flashing my BBB from uSD, and it has been doing so for over an hour. I was wondering if people have had similar experiences? Oct 02 15:25:07 zcarter: what are the board LEDs doing? Oct 02 15:34:00 veremitz: 0 is flashing the heartbeat pattern, 2 is rapidly flashing Oct 02 15:34:20 1 and 3 are off Oct 02 15:34:22 are you sure its actually flashing? Oct 02 15:34:22 then it's not flashing anything, it's just a running linux system Oct 02 15:34:37 okie doke. that would be a problem Oct 02 15:35:05 the default images are not flasher any more .. just so you're aware .. you have to modify them or use a special image from the bb debian wiki page .. Oct 02 15:35:25 Oh! okay. I didn't know that Oct 02 15:35:32 Are they bootable? Oct 02 15:35:33 you can log in on the system and uncomment one line in /boot/uEnv.txt to make the card a flasher Oct 02 15:37:21 the led pattern you're describing is a running system (that's busy doing stuff apparently, since led 2 is by default configured to indicate cpu activity) Oct 02 15:37:48 default led config is { 0: heartbeat, 1: sd card, 2: cpu, 3: emmc } Oct 02 15:37:49 Yeah that's why I thought it was flashing Oct 02 15:37:54 ahh got it Oct 02 15:38:10 so led 3 should be active during the flashing? Oct 02 15:38:26 flashing overrides the leds and shows a back-and-forth ("cylon" / "knight rider") led pattern Oct 02 15:38:43 got it. I just found the wiki page to flash the bbb Oct 02 15:38:56 didn't realize I needed to comment out the lines Oct 02 15:39:06 Thanks a bunch! Oct 02 15:39:15 the same wiki page also has ready-made flasher images Oct 02 15:39:54 but the only difference is uncommenting that one line in /boot/uEnv.txt so it's not really worth downloading a new image :) Oct 02 15:40:26 sounds like it! Oct 02 15:47:16 zmatt: there aren't flasher images on the main pages, unless jkridner reinstated them .. Oct 02 15:47:31 it seemed a stupid idea to me .. but the caliber of people downloading them seemed ... below average :/ Oct 02 15:47:47 perhaps someone can update me :) Oct 02 15:47:55 I'm assuming that with "wiki page" we mean http://elinux.org/Beagleboard:BeagleBoneBlack_Debian Oct 02 15:48:00 no Oct 02 15:48:03 yes. sorry Oct 02 15:48:08 not the "images" page via bb.org/ Oct 02 16:03:36 hi , anybody in here driving AC industrial servo drives with BeagleBone board ? Oct 02 16:03:55 I am planning to use one for a cnc big plasma cutting machine Oct 02 16:04:06 any advices ? Oct 02 16:05:09 be careful? Oct 02 16:07:36 yeah Oct 02 16:07:38 sure Oct 02 16:08:03 i mean , I would like to know if anybody have any similar project already Oct 02 16:08:35 and if there is any troubles driving big AC servo drives with that BB Oct 02 16:09:02 the drives should take PWM input and thats it afaik Oct 02 16:09:35 well the bbb has a fair number of pwm outputs Oct 02 16:09:42 AC 220V, 2 drives 1kW power, and 1 drive 750W all from DMM Tech Oct 02 16:09:45 and more can be made using pru if necessary Oct 02 16:10:29 what is pru ? Oct 02 16:11:00 programmable real-time unit. if you only need 3 pwm outputs then don't worry about it Oct 02 16:11:16 sounds like your main concern would be electrical interfacing Oct 02 16:11:45 including making sure not to couple some awful noise or voltage spikes back to the bbb i/o :) Oct 02 16:13:37 Are people have issues running PWM software on P8_13 with the BBBW with 4.9.50-ti-r61? Oct 02 16:14:01 set_: I thought you were using BBGW ? Oct 02 16:14:12 I am but I use the BBBW, too. Oct 02 16:14:14 I have both. Oct 02 16:14:20 ah ok Oct 02 16:14:30 zmatt: Do you use the BBBW at all? Oct 02 16:14:56 no Oct 02 16:15:02 Oh. Oct 02 16:15:15 zmatt: thx, i have to go now, but later i am back here :) Oct 02 16:15:42 RuntimeError: Problem with a sysfs file Oct 02 16:15:50 ^ That is my error. Oct 02 16:15:58 very descriptive Oct 02 16:16:02 I know? Oct 02 16:16:18 I'm assuming this is coming from some adafruit crap Oct 02 16:16:19 ? Oct 02 16:16:23 Yes. Oct 02 16:16:35 BBIO! Oct 02 16:16:48 by default I'd assume it's a bug in that Oct 02 16:16:50 :) Oct 02 16:17:02 Are their software gurus having issues? Oct 02 16:17:36 do they have any? Oct 02 16:17:50 I have no clue. I just thought they did. Oct 02 16:18:20 Off to github.com to promote the error. Oct 02 17:29:45 Hello every one! Oct 02 17:30:33 the WL led in wireless beaglebone is not blink. kindly help me to figure out this issue Oct 02 17:30:36 ??? Oct 02 17:59:53 what's the log for this channel? Oct 02 18:05:05 Hello. I was hoping someone could point me in the right direction. I have a Beglebone Black that I am tring to install new firmware to but although the SD card has the OS on it, the unit still uses the old OS. I can't seem to get it to install on the unit itself. Can anyone direct me to something that can help? Oct 02 18:10:40 kindly somebody help me to activate the wireless in beaglebone black wireless. It's WL led is not glow Oct 02 18:13:29 Over 100 people sitting idlely in this chatroom and no one can answer two simple questions. Why bother being here? , you and I will need to find answers to our questions somewehere else. Oct 02 18:14:26 Pezz: patience is a virtue. people are in different timezones or just busy with other stuff most of the day and may not always be paying attention to irc Oct 02 18:14:51 The why be signed in? Oct 02 18:15:46 that's pretty normal on irc. also, it's not uncommon to communicate across time (many irc clients will highlight or even separately log messages that contain your nickname) Oct 02 18:16:19 understood. Oct 02 18:17:18 as for your question, the images at https://beagleboard.org/latest-images are "standalone" images which just run from SD, but you can change those into flashers by uncommenting a single line un /boot/uEnv.txt. there's a paragraph on that page that explains that (below the "Recommended Debian Images") Oct 02 18:17:53 http://elinux.org/Beagleboard:BeagleBoneBlack_Debian has more detailed instructions, and also has premade flasher images Oct 02 18:19:04 flasher cards are slightly dangerous since booting a bbb with such a card inserted will wipe any existing contents of the eMMC. that's why the direct downloads at https://beagleboard.org/latest-images are no longer flashers Oct 02 18:19:10 Yes, thank you. However, I have a good image but when I try to flash it the board does not accept it and reverts to the previous OS. I can't get the flash memory to accept the new version. Oct 02 18:19:46 that sounds odd. what happens exactly? a failed flash would leave the emmc unbootable, not untouched Oct 02 18:21:01 When I flash the emmc it appears to be working and takes about an hour to complete. Then when the unit boots it doesn't have the new OS, it has the original one that I was trying to replace and boots to that version. Oct 02 18:22:00 that really makes no sense. step one of reflashing is erasing the emmc, so if it even *begins* the flashing procedure then the old OS is gone Oct 02 18:23:06 did you download a flasher image or did you modify a standalone image to become a flasher image? Oct 02 18:23:38 Thats what I thought. This is a bbb from a old Bitcoin mining rig so maybe it has a problem. Oct 02 18:23:55 oh you mean it isn't a bbb at all Oct 02 18:24:12 No it is. Oct 02 18:24:25 a controller for mining rigs? Oct 02 18:24:27 you mean the thing from antminer right? Oct 02 18:24:32 or something like that Oct 02 18:25:12 those guys make boards that are derived from the beaglebone design, but they're not beaglebones Oct 02 18:25:15 I believe it was an KNC unit. It has been modified and does not have a USB port on the board Oct 02 18:25:24 right, those are not beaglebones Oct 02 18:25:44 does it even have eMMC at all? Oct 02 18:26:39 Yes it does and it does say "Beaglebone" on it as well as "Beaglebone.org" Oct 02 18:27:01 yes well they can print anything they want on it, that doesn't make it so Oct 02 18:27:23 can you pastebin the kernel log? Oct 02 18:28:33 Yes I can in about a 1/2 hour or so. Oct 02 18:29:37 images of both sides of the pcb might also be useful Oct 02 18:29:53 sure, no problem Oct 02 18:39:30 afk, back in a bit Oct 02 18:43:31 zarzar: http://logs.nslu2-linux.org/livelogs/beagle/ Oct 02 18:43:57 thanks ee1932, found 'em Oct 02 19:00:27 back Oct 02 19:26:34 Looking for 'How-To's' / Guides / instructions /etc, related to building a Rover with the BeagleBone Blue...... Oct 02 19:26:58 Not much info available~ Oct 02 19:54:31 is it possible to transfer my BBB sd card image from one sd card to another (larger card)? Oct 02 19:55:19 * using windows 10 host OS Oct 02 20:02:59 yes Oct 02 20:03:00 * no Oct 02 20:03:19 actually, I suppose you can, it's just a bit icky Oct 02 20:05:23 you can just transfer the raw content of the card, then boot up the new card, repartition it (yes, the boot device, while running from it), reboot, then expand the filesystem to the new larger partition (ext4 supports expanding a mounted filesystem) Oct 02 20:06:26 doing this is a bit more convenient using a linux host system though... don't you have a usable system on the beaglebone's eMMC ? Oct 02 20:10:50 zmatt is in the house! Oct 02 20:10:58 Hello! Oct 02 20:11:15 I know you are busy right now...no issue. Oct 02 20:16:23 really, how do you know? you have a spy cam in my house? :p Oct 02 20:16:50 No spy cam here. Just a ESPN. Oct 02 20:38:36 zmatt: i only have a virtualbox ubuntu, i am trying copying with win32diskimager now Oct 02 20:39:43 zmatt: tried copying with diskinternals linux reader and writting with win32diskimager but the bbb would not boot the sd card Oct 02 20:41:51 zarzar: Use the other tool to copy your image. Oct 02 20:42:01 i.e. etcher! Oct 02 20:43:05 https://etcher.io/?ref=etcher_update Oct 02 20:43:13 set_: ok will try etcher Oct 02 20:43:42 Use 7-zip and etcher. That should work. Oct 02 20:44:09 I used etcher last night. Oct 02 20:44:23 what is 7zip used for in this process? Oct 02 20:44:31 compression tool Oct 02 20:44:54 You need to download the image file, i.e. .img file. Oct 02 20:45:09 You have to extract it the tz file to get the img file. Oct 02 20:45:20 no i want to copy an existing sd card, make an image, move to another larger sd card Oct 02 20:45:37 Oh. Please hold. I have a book on that. Let me read real quickly. Oct 02 20:45:45 haha ok Oct 02 20:49:04 So zarzar: You can access your info. (.img file and software) but you cannot get the .img file saved to the computer to address uploading that info. (.img file and software) to a larger SD card. Oct 02 20:49:40 Got it...please hold. Oct 02 20:53:34 zarzar: I am going to walk you through this but you have to be okay with my lack of understanding. Oct 02 20:53:59 set_: trying with win32diskimager now, writing image to larger card, i created the image from the other sd card Oct 02 20:54:10 set_: not sure if it will work or not Oct 02 20:54:22 Oh...okay. If you fail, let me know. I will walk you through this setup. Oct 02 20:55:05 set_: does that sound like a valid process that should work? Oct 02 20:55:31 Not to me but I do not use diskimager anymore. Oct 02 20:55:50 I was catching errors. Oct 02 20:56:25 set_: ok what was your process? what were you using to pull the sd card image? did you use etcher? seems like that is only for writing... Oct 02 20:57:10 Forget etcher. Look: df -h and tell me what you get. Oct 02 20:58:07 zarzar: what's "diskinternals linux reader" ? whatever you're using to make an image shouldn't care about whether it's linux or not Oct 02 20:58:13 just copy the raw bits Oct 02 20:58:44 (of the whole card, not the partition) Oct 02 20:58:48 yea the prob is that only some readers work since the file system is not a windows type (btfs or whatever) Oct 02 20:59:09 filesystem is (or rather, should be) completely irrelevant for this process Oct 02 20:59:41 I get what you are saying, e.g. just downloading the entire sd card to the main computer. Oct 02 21:00:08 I'd assume win32diskimager should be able to do it Oct 02 21:00:29 zmatt: in process now with win32diskimager Oct 02 21:01:36 it boots Oct 02 21:02:22 ok, so... now you won't have more space yet Oct 02 21:03:12 zmatt: right, so now i need to expand file system Oct 02 21:03:28 boots and runs, looks like it working fine, 8GB now Oct 02 21:03:48 oh, you mean it auto-expanded? Oct 02 21:04:05 no i mean the physical size is 8GB Oct 02 21:04:07 or was 8G the old size? Oct 02 21:04:11 ok Oct 02 21:04:18 sorry, i think i still need to expand Oct 02 21:05:08 so, anyway, so, you'll need to repartition the card now. make sure the partition's start offset remains the same in the process Oct 02 21:06:40 can you tell me sfdisk --version Oct 02 21:07:47 zmatt: sfdisk from util-linux 2.25.2 Oct 02 21:08:21 ok, old version, then I'm not going to take a chance with giving an sfdisk-based one-liner :) Oct 02 21:08:38 is this the command: resize2fs /dev/mmcblk0p2 from https://elinux.org/Beagleboard:Expanding_File_System_Partition_On_A_microSD Oct 02 21:08:49 you first need to repartition Oct 02 21:08:55 then reboot, then resize2fs Oct 02 21:09:15 walked through this but did not see an additional partition: https://elinux.org/Beagleboard:Expanding_File_System_Partition_On_A_microSD Oct 02 21:10:07 those instructions are from 2013 Oct 02 21:10:27 dang Oct 02 21:10:30 all images since a long time use only a single partition Oct 02 21:11:29 if you hang on a moment I'll make better instructions Oct 02 21:11:34 ok cool Oct 02 21:18:14 Sorry for interrupting earlier. If you guys need suggestions, please let me know. Oct 02 21:19:29 no worries set_ Oct 02 21:22:42 opt / script / tools Oct 02 21:23:25 sorry.../opt/scripts/tools Oct 02 21:24:18 I'm dragging the wiki page into the modern age ;) Oct 02 21:24:28 Cool! Oct 02 21:24:49 2017 and beyond! Oct 02 21:25:46 <<<< on break for five minutes while this BBB Wiki gets updated Oct 02 21:26:00 thanks zmatt! Oct 02 21:27:01 will be back later, have to go walk the dog and eat Oct 02 21:40:23 almost done, doing final check Oct 02 21:46:40 saved Oct 02 22:55:10 I just plugged in a 12v 2amps to my BB Blue, now it no longer boots Oct 02 22:55:30 Can anyone help? Oct 02 22:59:01 * zmatt . o O ( well, no, since you left ) Oct 03 00:30:47 Phew! Oct 03 01:31:13 How did that guy find a 12v, Barrel Jack? Oct 03 01:34:09 Bang! :D Oct 03 01:40:24 Hey veremitz: Do you use the BBBW? Oct 03 01:40:42 no .. I only got two BBB's Oct 03 01:40:51 I wanna get a BBblue though soonish Oct 03 01:41:51 Oh...those are great too. Oct 03 01:42:43 What are you going to make with a Blue? Oct 03 01:43:42 A set of pneumatic, rolling lawn mowers? Oct 03 01:44:23 ... Oct 03 01:45:46 i.e. locomotive inertia and blades could not hurt? Oct 03 01:46:34 All I have to say is poor lawn and geaux BBB! Oct 03 02:05:37 set_: I've got a 12V 2A PSU with a 2.5mm barrel jack Oct 03 02:05:45 for the beagleboard x15 Oct 03 02:05:54 Oh. Oct 03 02:05:55 they're a little pricey but they exist Oct 03 02:06:07 Where did you find that jack? Oct 03 02:08:28 ee1943: Did you ever get involved with the issue pertaining to that old software I showed you? Oct 03 02:08:54 the PWM on the BBBW? Oct 03 02:08:59 Yea. Oct 03 02:09:09 I checked the IRC logs and saw that you filed an issue with the adafruit guys Oct 03 02:09:10 got a link? Oct 03 02:09:23 Yea. Please hold. Oct 03 02:10:03 https://github.com/adafruit/adafruit-beaglebone-io-python/issues/168 is the link to the issue on GitHub.com. Oct 03 02:10:10 it's pretty tricky to debug with the crappy error message they've got Oct 03 02:10:29 Yep. I noticed that the person wanted me to look into strace. Oct 03 02:10:34 my gut tells me that the PWM isn't enabled Oct 03 02:10:47 That is what I thought. Oct 03 02:10:50 i.e. that specific pin Oct 03 02:11:14 I tried to enable it with bone_capemgr and config-pin. Oct 03 02:11:22 No-go so far. Oct 03 02:11:24 hmmm Oct 03 02:11:32 yeah that eliminates what I was going to say Oct 03 02:11:53 one option is manually turning the PWM off and on using the sysfs Oct 03 02:12:04 I figured that strace will show this fellow on GitHub exactly what my system states. Oct 03 02:12:05 Oh? Oct 03 02:13:05 So, I can go to the dir sys/fs and turn things on and off, heh? Oct 03 02:13:20 this link is decent, some of the paths he references might have changed though: https://briancode.wordpress.com/2015/01/06/working-with-pwm-on-a-beaglebone-black/ Oct 03 02:13:36 ... Oct 03 02:13:41 I will look at it. Oct 03 02:13:45 also re: strace, you can just install it with apt on the beaglebone. no need to compile from source Oct 03 02:13:58 oh...that is good news. Oct 03 02:15:10 That info. was complicated. Knowing me, I would have made more than one mistake. Oct 03 02:15:26 don't worry about it, we've all got to start from somewhere Oct 03 02:15:31 'configure' here and not there and this not that. Oct 03 02:15:56 have you tried getting the program to run using a different PWM pin? Oct 03 02:15:57 Yep. Oct 03 02:17:05 Oh...yes. I tried some other pins and found that bone_capemgr=GPIO_xx killed my system. Oct 03 02:17:18 I had to get another image file and boot. Oct 03 02:17:45 I tried the actual PWM name and it did not work. Oct 03 02:19:43 i.e. bone_capemgr=EHRPWM2B. Oct 03 02:20:12 I mean bone_capemgr=BB-EHRPWM2B. Oct 03 02:20:14 Sorry. Oct 03 02:20:22 no worries Oct 03 02:20:45 so the way it works is that bone_capemgr loads capes that might enable a bunch of different inputs and ouputs Oct 03 02:21:07 Oh. Oct 03 02:21:12 this is the list you can choose from: https://github.com/beagleboard/bb.org-overlays/tree/master/src/arm Oct 03 02:21:36 and so the BB-PWM{0, 1, 2} capes are the ones you're interested in Oct 03 02:21:46 Okay. Oct 03 02:21:59 the reason your system "died" was because you told it to look for a cape that doesn't exist Oct 03 02:22:09 Dang. Oct 03 02:22:49 I will check out those BB-PWMx.x.x capes and let you know what happens. Oct 03 02:23:14 Be back in the wind of lamb's jaw. Oct 03 02:25:27 yes, I've got to get going as well. I loiter in this channel though so if you need any help feel free to ping or PM me :) Oct 03 02:26:33 Okay. Thank you, again. Oct 03 02:35:15 ee1943: I found how to produce results via the capemgr. The issue was a problem with sysfs again. Oct 03 02:37:46 I am rebooting now to test if the default cape was in the way when I enabled one of those PWM capes. Oct 03 02:41:19 Well, something changed. Oct 03 02:41:20 ... Oct 03 02:41:34 RuntimeError: Problem with cape manager. **** ENDING LOGGING AT Tue Oct 03 03:00:00 2017
