**** BEGIN LOGGING AT Wed Jul 25 03:00:02 2018 Jul 25 04:31:20 hai i m trying to boot begalbone blue from uart in ubuntu 14.04 could you share the working bootlaoder images Jul 25 04:31:41 boot from uart? o.O Jul 25 04:32:20 yes ..uart 0 Jul 25 04:33:02 zmatt: Hello! Jul 25 04:33:06 I am learning Git. Jul 25 04:33:11 Update! Jul 25 04:33:16 Hhahaah. Sorry. Jul 25 04:33:48 "too little, too late!" Jul 25 04:33:49 I know it's theoretically possible, but I've never heard of anyone actually doing that... surely it takes ages to upload u-boot via xmodem, let alone a kernel or initramfs Jul 25 04:34:53 and I don't see why you'd ever want to use uart boot instead of sd card or usb Jul 25 04:36:46 because my board is customized one in this sd card slot is not working and we are using usb for power supply so i have the only way to boot that is uart Jul 25 04:39:45 why would using usb as power supply conflict with using it to boot? a standard usb port can deliver 500 mA and nowadays it's quite common (at least on laptops) to have a power that can deliver much more than that (to support charging a phone) Jul 25 04:39:56 *to have a port Jul 25 04:43:20 ...If I wanted to make some motors go on the BBBlue and I added a LiPo battery pack (2 cell), would I have to use the power out connection to make this possible? Jul 25 04:43:21 ... Jul 25 04:43:43 what do you mean? Jul 25 04:43:55 They have LiPo in and power out on the BBBlue. Jul 25 04:44:30 I'm sure there are various power outputs on the blue, but I don't understand how that's related to your question Jul 25 04:44:39 I have all my other connections made, e.g. except for the BBBlue's power in and power out. Jul 25 04:44:42 ... Jul 25 04:45:22 after connecting the lipo back via the battery header, you can charge it by providing power via the 12v power input Jul 25 04:45:59 I saw the power out pins. There are a bunch of pins in that little power out "pinage." Jul 25 04:46:12 yes, and? Jul 25 04:46:28 I have only two wires for to connect to it. Jul 25 04:46:28 (the word you're looking for is "header") Jul 25 04:46:32 Oh. Jul 25 04:46:34 header! Jul 25 04:46:37 connect what? Jul 25 04:46:51 A power board for a drone. Jul 25 04:47:20 But that little header does not seem like the type. Jul 25 04:47:48 zmatt: Do you know the name for that little header pin? Jul 25 04:48:04 off hand? Jul 25 04:48:38 schematic calls it PWR, or the "Prototyping Power Pads" Jul 25 04:49:07 Oh. Hmm. I am not sure if that is an actual pin setting. Jul 25 04:49:09 which you can use for powering 5v or 3.3v external electronics Jul 25 04:49:12 I will have to look that up. Jul 25 04:49:16 Okay. Jul 25 04:49:19 "pin setting" ? Jul 25 04:49:25 sorry...header. Jul 25 04:49:44 it's a JST connector Jul 25 04:49:49 Aw! Jul 25 04:49:57 JST! Jul 25 04:49:57 so if you're talking about an actual pin header then I'm not sure which you're talking about Jul 25 04:50:10 How can I show you a photo? Jul 25 04:50:33 I have a photo of the labeling on the BBBlue. Jul 25 04:50:39 but the connector or header should be labeled on the silkscreen on the pcb Jul 25 04:50:47 just tell me the name of the connector Jul 25 04:51:08 Let me look up the name. Please hold. Jul 25 04:53:22 Oh. Jul 25 04:53:32 I think you are right. Power Prototyping Rails. Jul 25 04:54:11 JST-SH Jul 25 04:54:36 I was mistaken for thinking it was not listed as something I could understand. Jul 25 04:54:44 so it's a connector, not a header Jul 25 04:54:50 Yes sir. Jul 25 04:54:50 JST-SH is the connector type Jul 25 04:55:50 It is a four pin connector but it does not specifically call it a power out connector. Jul 25 04:56:02 https://raw.githubusercontent.com/iplayfast/beaglebone-blue/master/docs/BeagleBone_Blue_pinouts.png Jul 25 04:57:02 That works. I was discussing the "power out" on that page. Jul 25 04:57:14 It has four pins in the connector. Jul 25 04:57:55 anyway...I think I can try to make that work. I think. Jul 25 04:58:19 zmatt: Do you know what happened to "myself." Jul 25 04:58:50 no idea Jul 25 04:58:57 so, what was your actual question? Jul 25 04:59:25 Can I use that "Power Out" connector to power a drone power board? Jul 25 04:59:42 3.3v! Jul 25 04:59:48 or 5v! Jul 25 04:59:51 if it runs on 5v or 3.3v and doesn't require much current Jul 25 05:00:09 Oh. Which connector would you recommend for more current? Jul 25 05:00:23 but "drone power board" sounds more like something that would be connected directly to the battery? Jul 25 05:00:48 assuming it's designed to do so normally Jul 25 05:00:58 Oh. Jul 25 05:01:01 Okay. Jul 25 05:01:28 I am using this BBBlue as a microcontroller to support ArduPilot for drone usage. Jul 25 05:01:32 note I'm basically just speculating here since you haven't provided any information of substance about what this board needs Jul 25 05:01:40 I know. Jul 25 05:01:46 The damn board came w/ no info. Jul 25 05:01:59 I will have to test it. Jul 25 05:02:38 Plus, I have motors, ESCs, and some odd connections. Jul 25 05:02:53 Oh well. Jul 25 05:02:56 I will test it soon. Jul 25 05:03:13 That photo works, though. I apperciate it. Jul 25 05:03:15 try to avoid starting a fire when messing around with a lipo pack Jul 25 05:03:25 I know. I heard they blow. Jul 25 05:03:43 Boom-boom batteries. Jul 25 05:04:11 I charged it today for 30 minutes on concrete. Jul 25 05:04:11 this is also a good photo: it shows the connector labels quite clearly, and the little white dot that marks which side of the connector is pin 1: https://makezine.com/wp-content/uploads/2017/04/BeagleBoneBlue_BoardsGuide-3.jpg Jul 25 05:04:25 Okay. Jul 25 05:04:50 though they should have rotated it 180 degrees Jul 25 05:05:12 (the labels that aren't sideways are upside down) Jul 25 05:05:33 Okay. Jul 25 05:06:09 I only got a fourth charge from the 30 minute charging that took place. Jul 25 05:06:20 I will have to purchase a new one. Jul 25 05:08:16 anyway... Jul 25 05:08:19 Later for now. Jul 25 06:06:36 hello i downloaded the latest image and now i putted the sd card into my beagleboneblack. the next step is if i desire to flash the image to an emmc , do i need that ? Jul 25 07:30:49 i am having a weird issue when loading a newer kernel, my old kernel knew how to boot from mmcblk0p2 but this doesn't work with my new kernel it wants mmcblk1p2, when i boot the new kernel and do a lsblk it is indeed listed as mmcblk1 is there anyway to change this behaviour without changing my bootloader ? Jul 25 07:31:16 probably not since it's a problem in the bootloader Jul 25 07:31:35 why not simply upgrade it? Jul 25 07:31:49 i can't remotely upgrade a bootloader ? Jul 25 07:31:54 why not? Jul 25 07:32:47 i actually do not know :D Jul 25 07:33:18 you'll need to be careful, but that's equally true for the kernel upgrade Jul 25 07:34:54 you can either replace the files in the FAT partition on /dev/mmcblk1p1 or delete that partition entirely and dd the MLO and u-boot.img to fixed offsets (I think I'd personally do the latter to match the standard images) Jul 25 07:35:08 but why does the new kernel want mmcblk1p2 while the bootloader passes mmcblk0p2 ? i am just trying to get a understanding why this happens Jul 25 07:35:21 I actually explained why last time Jul 25 07:35:57 ok i'll have a look back in the history :) Jul 25 07:36:32 https://pastebin.com/raw/snGSC3G4 Jul 25 07:37:25 basically the kernel behaviour was wrong, but u-boot's script was made to work with that Jul 25 07:37:46 (mostly anyway, it failed to boot from eMMC if a non-bootable sd card was inserted at boot time) Jul 25 07:47:06 i want to flash the image to the emmc but the 4 usr leds are not flashing only the heartbeat one Jul 25 07:47:13 what am i doing wrong ? Jul 25 07:47:46 zmatt: thanks :) now it's clear. Jul 25 07:50:04 hello, have you touched the /boot/uEnv.txt file? Jul 25 07:50:24 (side note: hello is an awkward name for a chat handle) Jul 25 07:50:47 i am doing it on windows i thought that i dont have to to it with this file Jul 25 07:50:56 but where can i find that file ? Jul 25 07:51:50 hello, the default behavior of the images you would download is to *boot*, not to *flash* Jul 25 07:52:05 so, if you want it to flash, you have to uncomment the last line of /boot/uEnv.txt Jul 25 07:52:34 On Windows, I am not sure how easy it is to edit that file; I have not idea what file system /boot uses Jul 25 07:52:45 you can't on windows, just boot the bbb and do it there Jul 25 07:52:54 then reboot the bbb and it'll flash the eMMC Jul 25 07:52:55 ^^^ beat me to it Jul 25 07:53:26 :-) Jul 25 07:54:46 i wrote the image on sd card, now i put it in and i have to hold the 3rd button on the board while i am power the board ? Jul 25 07:55:15 that button is very rarely needed Jul 25 07:55:54 and all 4 leds have to be constant ? Jul 25 07:56:01 i try it one moment Jul 25 07:56:30 when it's done flashing it turns itself off Jul 25 07:57:13 i know but which leds have to shine ? Jul 25 07:57:21 I just made an image of my flash drive, for archival purposes. However, the last 7GB belong to unpartitioned space. Can I use truncate to lop off the unused data, and still have a flashable image? Jul 25 07:57:52 dcmertens: yes, you can trim off unpartitioned space Jul 25 07:57:57 thanks Jul 25 07:59:26 I often just image the filesystem rather than the whole disk, and shrink that to minimum size with resize2fs -M Jul 25 08:00:31 then to flash I have a script that erases, partitions, installs bootloader, writes filesystem and expands it to fit the partition, and mounts it to set the hostname, generate ssh keys, generate machine id, etc Jul 25 08:02:01 that sounds pretty clean. Do you have those scripts on github? Jul 25 08:08:12 during flashing the image to the emmc which leds should shine ? Jul 25 08:12:13 ? Jul 25 08:12:36 a repeating pattern: led0 - led1 - led2 - led3 - led2 - led1 - led0 - .. etc Jul 25 08:13:32 led 3 is constant and 0 is in heartbeat Jul 25 08:13:40 i am doing sth wrong Jul 25 08:14:03 did you modify the /boot/uEnv.txt file on the sd card as instructed previously? Jul 25 08:14:33 i am doing it on windows as i said and u said i dont have to do this Jul 25 08:14:58 that is not what I said Jul 25 08:16:22 along those lines... Jul 25 08:16:43 i dont understand where i can find this file ? Jul 25 08:16:45 you can't modify it on windows, but you can simply modify it by booting the bbb from sd card (as you now have) and then log in and modify the file Jul 25 08:16:56 e.g. with sudo nano /boot/uEnv.txt Jul 25 08:17:26 I have this nice new image ready for flashing, but the flasher says this: https://pastebin.com/BuZEH4LL Jul 25 08:17:27 where do i have to login ? Jul 25 08:17:54 hello: ... Jul 25 08:17:59 hello: on the bbb Jul 25 08:18:03 hello: use putty Jul 25 08:18:23 dcmertens: what am I looking at? Jul 25 08:18:55 zmatt, I have copied the output of the J1 tty device Jul 25 08:18:57 what flasher are you using? Jul 25 08:19:12 this is what I get from an image that boots from SD card Jul 25 08:19:28 but when I enable the flasher by uncommenting the last line of uEnv.txt Jul 25 08:19:35 I encounter trouble Jul 25 08:20:05 dcmertens: oh I don't know anything about that script, sorry Jul 25 08:20:15 my bad Jul 25 08:20:17 maybe it doesn't work without initramfs? Jul 25 08:20:23 oh!!! Jul 25 08:20:25 I'm just making a wild guess Jul 25 08:20:27 hahaha Jul 25 08:20:35 that well could be Jul 25 08:21:09 zmatt: why is this standing nowhere? the tutorial is so bad for a person who is doing this the first time Jul 25 08:21:17 well that's fairly easy to test... Jul 25 08:22:17 hello: a link to step by step instructions for flashing was given in the getting-started guide Jul 25 08:23:13 hello: you've simply shown repeatedly that you don't really read carefully what is being said, neither in documentation nor here in chat Jul 25 08:23:31 that is the root cause of your difficulties I think Jul 25 08:23:47 yeah but there is nothing saying about that i have to work with putty Jul 25 08:24:34 hello: can you link to the instructions that explain how to turn the image into a flashing image? Jul 25 08:24:40 I am curious what they say Jul 25 08:25:07 https://beagleboard.org/getting-started the last step of step 0 Jul 25 08:25:50 okay I'll admit that there seems to be a lack of reference to ssh in general... I guess it's implied for anyone with any previous experience with embedded systems, but you're right that it shouldn't assume such a thing Jul 25 08:26:40 in putty i have to enter now the ip address 192.168.7.2, right ? Jul 25 08:27:24 yes Jul 25 08:28:12 okay im in Jul 25 08:29:52 Hello all, what is the best wifi module for Beagle board industrial? Jul 25 08:31:06 zmatt: i write debian as login and then i cant enter the passwd Jul 25 08:32:08 it doesn't echo the password as you're typing it Jul 25 08:32:52 okay im in Jul 25 08:35:48 does anybody know if the channel log bot is working? Jul 25 08:36:10 rarely I think Jul 25 08:36:14 int the Env.txt i cant find the lines as in the tutorial Jul 25 08:38:13 all the way at the bottom Jul 25 08:38:33 ##enable Generic eMMC Flasher: ##make sure, these tools are installed: dosfstools rsync #cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh Jul 25 08:38:46 this is what i red there Jul 25 08:39:07 we know what it says, don't copy paste into chat Jul 25 08:39:15 sorry Jul 25 08:39:27 do i have to uncommand the cmdline.... Jul 25 08:39:30 ? Jul 25 08:40:25 the instructions on the wiki seem very unambiguous to me Jul 25 08:40:51 it states exactly which part you need to find in the uEnv.txt and shows which change to make Jul 25 08:41:15 well, it would help if the instructions indicated that said line is at the bottom of the file Jul 25 08:41:57 it would perhaps help in locating the line more easily yes. fortunately for hello we've also mentioned that fact here in chat Jul 25 08:42:07 true. :-) Jul 25 08:42:38 I can understand why you wouldn't include that line in the wiki though, since I don't know if it's really true that it's the last line of the file in every image that a person might want to flash Jul 25 08:42:45 I just know it's true in current images Jul 25 08:44:18 really? I reasoned it's always the last line so that no matter what else you have in your uEnv.txt, uncommenting it will work, because there is nothing to override it Jul 25 08:44:34 I would be shocked to see it located anywhere else Jul 25 08:44:41 but I don't have any data to back that up Jul 25 08:44:58 git pull Jul 25 08:45:06 s/shocked/a bit surprised/ Jul 25 08:45:10 hello: you can skip those optional steps Jul 25 08:45:17 that's why they're optional Jul 25 08:45:29 (honestly I don't even know why they're included) Jul 25 08:45:41 will they change sth big ? Jul 25 08:46:07 they're probably in case you want to turn an old image into a flasher and want to have any improvements that may have been made to the flasher Jul 25 08:46:16 okay Jul 25 08:46:19 not relevant when you've just downloaded the latest image Jul 25 08:46:40 now i uncommanded that line and now i do the step with the boot and power button? Jul 25 08:46:48 just reboot Jul 25 08:47:08 (and you mean "uncomment", not "uncommand") Jul 25 08:47:24 yeah Jul 25 08:52:30 anybody know where update-initramfs is located? Jul 25 08:52:35 It does not appear to be in my path Jul 25 08:52:41 * dcmertens realizes he can check the deb Jul 25 08:52:58 /usr/sbin Jul 25 08:53:15 but didn't you remove initramfs-tools ? Jul 25 08:53:36 oh dangit Jul 25 08:54:46 hahaha Jul 25 08:55:12 if I try to "sudo apt-get purge initramfs-tools", it tells me I also need to get rid of my kernels! Jul 25 08:55:34 try: sudo apt-get install initramfs-tools/stretch Jul 25 08:55:42 * dcmertens tries Jul 25 08:55:53 or include the --reinstall option maybe Jul 25 08:56:33 the first one did the trick Jul 25 08:56:42 the (completely unnecessary) kernel -> initramfs dependency was the reason for the dummy package in the first palce Jul 25 08:56:45 *place Jul 25 08:57:25 really? Hmm... interesting Jul 25 08:58:08 as a substitute for removing initramfs-tools Jul 25 09:03:54 now the lights gone out of the board.. now i have updated the board with the latest software Jul 25 09:03:58 fun fact: you can mount nfs in initramfs Jul 25 09:04:15 hello, yes; pop out the card and hit the reset button Jul 25 09:04:25 power button Jul 25 09:05:39 can u decide please Jul 25 09:05:49 listen to zmatt Jul 25 09:05:50 always Jul 25 09:06:27 He knows what he's talking about; I'm just here for the laughs Jul 25 09:07:02 lol Jul 25 09:10:29 so, fun fact, update-initramfs does not want to produce anything for me Jul 25 09:10:31 :/ Jul 25 09:10:49 sudo update-initramfs -kall -c Jul 25 09:10:57 ^^^ produces nothing Jul 25 09:11:26 argh Jul 25 09:11:28 n/m Jul 25 09:11:31 sudo update-initramfs -k 4.14.55-bone16 -c Jul 25 09:11:38 ^^^ this seems to be doing something Jul 25 09:14:26 wow, booting with initramfs seems to have added 20s to the boot time Jul 25 09:14:35 anyway, let's see if the flasher works Jul 25 09:16:44 zmatt, that did it. Apparently it is needed for the flashing process Jul 25 09:17:33 kinda makes me want to update the flashing script to remove that file at the end of the flash, though Jul 25 09:19:14 should the beagleboard be a network adapter in the devicemanager ? for me its portable devies Jul 25 09:19:50 devices* Jul 25 09:54:08 hi Jul 25 09:54:43 I work with a bbw Jul 25 09:55:31 beaglebonewhite, now that's vintage Jul 25 09:56:22 at few day I am done a board update and I pass the kernel 4.4.x to 4.14.56 Jul 25 09:57:03 sorry beaglebone black wireless Jul 25 09:58:55 now I can't pass the board in standby mode I have just the mem mode and the wake up don't work (rtc, ttyS0, gpio...) Jul 25 09:59:56 some thing was change in the command fore the power management ? Jul 25 10:02:52 I reinstall a kernel 4.4.113-ti-r149 and all work well Jul 25 10:24:29 hi Jul 25 10:24:49 when the board inserted SD card is turn on, it doesn't boot as SD card. but if SD card is poped and pushed again, it recognizes a SD card and boots as SD card. I suspect that BIOS is faster than interrupt that's why it can't recognize a SD card. i want to know this problem certainly. Jul 25 10:41:17 philippefouquet: hmm, something you might want to bring up with rcn, probably best on the google group. Jul 25 10:42:04 codeError110: sorry? what are you trying to do? boot from sd-card? Jul 25 11:09:49 can anybody help me, why i cant install node red onto the beagle bone Jul 25 11:10:06 error : failed to fetch ... Jul 25 11:13:42 ? Jul 25 11:19:02 mister: please be more verbose Jul 25 11:21:02 i want downloaded the newest image, flashed it to the emmc and now i want node red i got the 4gb version but when i want to start node red it says unable to listen on 127.0.0.1:1880 Error: port in use Jul 25 11:21:18 have downloaded * Jul 25 11:27:11 then configure it to listen to a different port Jul 25 11:28:25 how Jul 25 11:29:15 I haven't touched nodered, but I'm sure it has documentation Jul 25 11:31:28 tbr: thank I will ask Jul 25 11:48:42 How can i run an iot core on the beagle bone ? Jul 25 11:49:42 what's an "IoT core"? Jul 25 11:50:02 like an server Jul 25 11:50:33 well, the beaglebone is a linux computer and you can run server software on it Jul 25 11:50:41 an how Jul 25 11:50:52 do you have a link Jul 25 11:51:07 to what? Jul 25 11:51:28 maybe you should try being even vaguer, try: "I want to do a thing, how do I do it?" Jul 25 11:51:50 "by doing THAT /other/ thing obviously, duh!" Jul 25 11:52:55 mister: We would really like to help you, but for that you should explain a bit more what you are doing and what you want to achieve. Jul 25 11:53:30 mister: please keep in mind that we do not sit next to you and can not see what you are doing. So please explain such things so that we can understand your situation better. Jul 25 11:56:58 i am building kernel modules/driver and i notice that the folder with the version name has a + appended to it. why is this? sometimes it has it and sometimes it doesn't Jul 25 11:57:14 like so: lib/modules/4.1.30+ Jul 25 11:58:46 you mean an out-of-tree module? Jul 25 11:58:59 also, you're not using a -bone or -ti kernel? Jul 25 12:00:02 this is bone right? https://github.com/beagleboard/linux Jul 25 12:00:31 are you using this? https://github.com/RobertCNelson/linux-dev Jul 25 12:01:06 uhh that'll depend on the branch you pick. to be honest I don't use the patched snapshot repos other than if I want to link to e.g. snippets of driver code Jul 25 12:02:33 to build a kernel it makes more sense to use rcn's bb-kernel (for -bone) or ti-linux-kernel-dev (for -ti) repository, which is also how he builds kernels Jul 25 12:04:00 or actually https://github.com/beagleboard/kernel Jul 25 12:04:21 never heard of that repo Jul 25 12:04:27 meh, still wrong Jul 25 12:04:29 looks completely unmaintained Jul 25 12:04:41 I'm looking for the kernel build scripts. I always find the wrong ones first Jul 25 12:04:50 I just mentioned the repo names for that Jul 25 12:04:59 https://github.com/RobertCNelson/bb-kernel for -bone Jul 25 12:05:07 https://github.com/RobertCNelson/ti-linux-kernel-dev for -ti Jul 25 12:05:19 (no idea why the naming is so inconsistent, but *shrug* ) Jul 25 12:06:02 i see Jul 25 12:06:38 its scripts will check whether necessary host tools are installed, create a patched kernel tree, apply configuration, compile the kernel, modules, and dtbs, and build a debian package from it Jul 25 12:08:41 regarding your original question, maybe the + suffix indicates a modified kernel tree? I've never seen it myself but the version suffix is being overridden by rcn's scripts so that would explain that Jul 25 12:09:13 I add a custom suffix on top of that to keep my custom kernels distinguished from rcn's, e.g.: https://github.com/dutchanddutch/bb-kernel/blob/am33x-v4.14/version.sh#L48 Jul 25 12:15:09 i have so much to learn -.- Jul 25 12:15:24 does anybody know why there are a gazillion scripts in /opt/scripts/tools? Jul 25 12:15:29 it seems like most of them are old Jul 25 12:16:10 I discovered long ago that I need to modify one of them to write a proper fstab when I perform a flash, but the file I used to modify is not the right one anymore, so it seems Jul 25 12:19:10 Hello, i have a server.exe and whant to run this on my beagleboneblack. does somebody have a tutorial ? i cant find anything Jul 25 12:19:19 perhaps a better question: how do I set up a SD card so that when it flashes, it produces the correct fstab? Jul 25 12:20:10 mister, in short, that is a question about linux system administration Jul 25 12:20:15 just so you know roughly where you're headed Jul 25 12:20:42 is your server.exe a linux executable, or Windows? Jul 25 12:20:48 i have the exe on my windows pc is this a problem ? Jul 25 12:20:54 probably Jul 25 12:21:09 can you execute it on Windows? Jul 25 12:21:20 if so, you will have to recompile it under LInux Jul 25 12:21:30 yeah but i think it is also for linux Jul 25 12:21:55 do you have a reference explaining that, because this is new to me Jul 25 12:22:37 your BeagleBone is a Linux machine running on an arm architecture, whereas your main machine is a Windows box probably running on x86 Jul 25 12:22:39 i dont know a reference but you can compile it also on linux i think Jul 25 12:22:49 oh, yes, if properly written Jul 25 12:23:42 so, I suggest asking google about how to (1) compile a program on linux and (2) how to start a server on linux on boot-up Jul 25 12:24:27 i dont understand how i will get the file to the beaglebone Jul 25 12:24:37 im working with ssh and putty Jul 25 12:24:59 ssh will do it. Use that to copy the source code. Do you have a tutorial for that? Jul 25 12:25:22 i have nothing for that all im doing that for the first time Jul 25 12:25:42 fun times. :-) Jul 25 12:26:46 the source code is very big for that all i dont understand everything how to do that Jul 25 12:27:12 mister, here is a youtube video that google suggest to me when I asked about "how to copy file from windows to beaglebone" Jul 25 12:27:32 here's a blog: https://billwaa.wordpress.com/2014/10/08/beaglebone-black-file-transfer-with-pc-using-scp/ Jul 25 12:28:12 Personally, when I used to use Windows, I preferred bitvise over putty Jul 25 12:28:20 it has a built-in file browser, with drag-and-drop support Jul 25 12:28:22 check out https://www.bitvise.com/ssh-client Jul 25 12:28:30 okay Jul 25 12:28:45 but it would work with putty? Jul 25 12:28:55 it is an alternative to putty Jul 25 12:29:03 with other bells and whistles Jul 25 12:29:16 it certainly won't get in the way of putty, though Jul 25 12:33:01 mister, are the sources for you server public? I ask because if you use MS project stuff to organize the compilation process, you will have to do a bit of work/research to compile it on linux Jul 25 12:33:18 I figured I could offer to look over them quickly, if they are on github or something Jul 25 12:37:38 no im a student in a company and its their software Jul 25 12:38:35 i can tell you that it is a server i can connect to and request over http requester and that i want to to on beaglebone Jul 25 12:38:49 do* Jul 25 12:40:08 mister, to compile it, do you run the Compiler from Visual Studio, or does it have a Makefile? Jul 25 12:40:31 if the latter, then there's a good chance you can compile it on Linux with a small amount of work Jul 25 12:40:34 it has a makefile Jul 25 12:40:41 good Jul 25 12:41:47 and ? Jul 25 12:44:36 anyway i got a kernel working and modules loaded. with the source from here https://github.com/beagleboard/linux Jul 25 12:45:12 but it seems that certain things do not work, like lsusb says -99 and no network interfaces show up Jul 25 12:45:18 mister, if you know nothing about Linux, then that means you may no nothing about compiling on Linux. If you didn't have a makefile, you'd have yet another thing to learn about. You have a makefile, so one less hurdle. Jul 25 12:45:53 so should i give up and try a ti or bone version, which were shared? Jul 25 12:55:38 but what do if i have to do know ? i have to compile the makefile into linux ? Jul 25 12:56:21 mister, once you copy your project over the beaglebone with bitvise, then log in over putty or bitvise's ssh, cd into the project directoyr, and run make Jul 25 12:56:35 with luck, you'll have a working executable Jul 25 12:56:41 and thats all ? *_* Jul 25 12:56:46 almost Jul 25 12:56:53 that means you could ssh onto the machine and run it Jul 25 12:57:00 it does not mean it'll start when you boot the BB Jul 25 12:57:33 that doesnt matter if it runs when i click something Jul 25 12:57:54 i only want the connection from the server on beaglebone to my pc Jul 25 12:58:27 I am not entirely sure what kind of arrangement or startup you are looking for, based on that description Jul 25 12:58:38 but, well, one step at a time Jul 25 12:58:43 https://www.youtube.com/watch?v=u_ohQMGV4Ug will this also work for me ? Jul 25 12:59:03 to copy the files to the beagle bone or is bitvise easier ? Jul 25 12:59:16 I found bitvise easier Jul 25 12:59:39 If you have installed it, I would just use that Jul 25 12:59:51 I found the interface very Windows-y, i.e. intuitive for my Windows brain Jul 25 13:00:33 Which version do i need of bitvise ? Jul 25 13:01:15 do i want to connect to an ssh server or will i create one that other cann connect Jul 25 13:01:23 the second if im right ? Jul 25 13:01:30 no Jul 25 13:01:35 the bb will have an ssh server running Jul 25 13:01:39 you want to log into it Jul 25 13:02:42 If by version you mean server vs client, you want the SSH client Jul 25 13:03:12 Indeed, the query on this download page seems to address you question directly: https://www.bitvise.com/download-area Jul 25 13:06:53 okay Jul 25 13:09:03 dcmertens: I just asked someone i only have to copy and make the makefile and i will able to run it Jul 25 13:09:55 mister, I'm going to assume that you've also copied your source files. :-) Jul 25 13:10:15 good, sounds like you work with devs who know how to write cross-platform stuff Jul 25 13:26:03 can i copy only files with the psftp to beaglebone ? if i want to copy the project it says unable to open Jul 25 13:26:29 I don't know, it's been a long time since I used any of that Jul 25 13:27:39 does anybody know why "poweroff" and "shutdown now" both cause a reboot instead of power off? Jul 25 13:36:05 dcmertens: ehh what? Jul 25 13:36:15 they absolutely should not Jul 25 13:36:34 zmatt, it turns out that sometimes it reboots, and sometimes it listens Jul 25 13:36:49 dcmertens: sounds like a hardware problem Jul 25 13:36:49 I haven't played with it enough to know when I get what Jul 25 13:36:54 no..... Jul 25 13:36:56 or a software problem Jul 25 13:37:02 that's more like it! Jul 25 13:37:18 thankfully, for this BB, it actually powered off after the third time I asked Jul 25 13:37:40 this is with external stuff connected right? Jul 25 13:37:46 yeah Jul 25 13:37:54 by external I mean eth Jul 25 13:38:03 no I meant expansion header stuff Jul 25 13:38:04 and monitoring via J1 Jul 25 13:38:10 no expansion headers on this one Jul 25 13:38:17 okay then it's getting weird Jul 25 13:39:26 any chance it might be something like a watchdog timeout during shutdown? Jul 25 13:39:50 hmm, I consistently get warnings about watchdog timers not working, or some such Jul 25 13:39:58 ehh Jul 25 13:40:02 gimme a sec, I'll post what I see Jul 25 13:40:19 on the clean power-down, I had no such warnings Jul 25 13:41:25 hmm, well I've seen warnings about that over the last couple of days, but nothing at the moment Jul 25 13:41:51 I'm in the middle of reconfiguring power to my boards, I'll try to power cycle them when all of that is in place Jul 25 13:41:53 in a couple of minutes Jul 25 14:18:35 Duality: sounds like you did something wrong :) Jul 25 14:20:48 Duality: you should be able to produce a working kernel from the beagleboard/linux tree if you pick the right branch, use the right kernel config, and correctly build and install the kernel, but overall it's a lot easier and less error-prone to use the build repo Jul 25 14:22:03 another reason to use the build repo is because that makes it easier to add custom patches or customize the kernel config and still be able to easily upgrade to newer versions Jul 25 14:23:31 (and presumably you do want to customize it, otherwise there'd be no reason to compile the kernel yourself in the first place) Jul 25 14:41:09 debuging this thing isn't always so clear to me Jul 25 14:41:36 i just tried from the ti repo, and it won't load my modules Jul 25 14:44:21 what do you mean? Jul 25 14:48:20 i am almost free from work, but for example iptables can't modprobe a certain module it needs Jul 25 14:48:34 try: sudo depmod Jul 25 14:48:43 to ensure the modules are correctly indexed Jul 25 14:49:05 this is supposed to happen automatically after installing a kernel, but I noticed that for some reason it doesn't seem to happen always Jul 25 14:49:46 i ran depmod with root Jul 25 14:49:53 there is no other user in this system :) Jul 25 14:50:02 depmod doesn't complain or anything Jul 25 14:50:16 okay, so check if this fixed the problem Jul 25 14:50:36 you're running everything as root? ... ew Jul 25 14:50:53 i know, not my choice Jul 25 14:54:02 just did a depmod again it does not fix it :) i am probably missing something simple :D Jul 25 14:54:56 running depmod more than once does nothing (unless you installed or removed kernel modules since the last depmod) Jul 25 14:55:48 but I mean, if iptables needs a certain module and is unable to load it... is the module actually present in the filesystem? Jul 25 14:56:14 i have multiple directories in my /usr/lib/modules could that be a problem Jul 25 14:56:31 kernel modules should be in /lib/modules/$VERSION Jul 25 14:57:16 the system before i started working on it had them in /usr/lib/modules Jul 25 14:57:43 again, if you use rcn's build repository then the scripts will directly produce a debian package you can install or a tarball you can expand with all files in the right place Jul 25 14:57:50 wtf, in /usr/lib/modules ? that makes zero sense Jul 25 14:58:47 ha Jul 25 14:58:55 so i copied them to /usr/lib/modules Jul 25 14:58:59 and ran depmod Jul 25 14:59:06 and when i look in /lib/modules it's there Jul 25 14:59:14 "it" ? Jul 25 14:59:30 the files depmod produces you mean? Jul 25 14:59:56 i though you implied that i had to copy my modules to /lib/modules Jul 25 15:00:10 (i haven't) Jul 25 15:00:41 they're normally installed in /lib/modules and I'm surprised if having them installed in /usr/lib/modules works *at all* Jul 25 15:01:11 but it sounds like you have a weird system, so who knows Jul 25 15:01:39 ok i think there is a misunderstanding? or atleast i lost it :D Jul 25 15:01:59 i copy my modules to /usr/lib/modules, but i should instead copy them to /lib/modules? Jul 25 15:02:16 anyway i'll have to get back on it tommorow. so thanks for the help so far! Jul 25 15:02:20 on a normal linux system /usr/lib/modules does not exist Jul 25 15:02:23 ~$ ls /usr/lib/modules Jul 25 15:02:23 ls: cannot access '/usr/lib/modules': No such file or directory Jul 25 15:02:50 hello Jul 25 15:02:55 Duality: based on some googling it looks like only Arch Linux puts them there, and I have no idea what the hell they're thinking Jul 25 15:05:35 im having trouble with a cape and according to nelson the only he only way to debug/etc is thru the debug serial port in u-boot. Jul 25 15:06:40 depends on what sort of trouble Jul 25 15:07:11 i want to know if its being loaded Jul 25 15:07:50 i dont know if its dtc is being loaded by u-boot Jul 25 15:08:22 that can typically be easily determined simply by looking at the DT representation in /proc/devicetree, or even more simply by looking at the current pinmux Jul 25 15:08:23 is there any way to read serial from inside bbb? Jul 25 15:09:06 eh, that doesn't even make sense Jul 25 15:10:24 i see so i need a serial device? Jul 25 15:11:07 if you want to see the serial output then see https://elinux.org/Beagleboard:BeagleBone_Black_Serial Jul 25 15:11:18 but if you just want to know whether your overlay is being loaded, I just gave two alternatives Jul 25 15:11:27 Hey, I thought you guys might be interested in this blog by freenode staff member Bryan 'kloeri' Ostergaard https://bryanostergaard.com/ Jul 25 15:11:27 or maybe this blog by freenode staff member Matthew 'mst' Trout https://MattSTrout.com/ Jul 25 15:11:27 Read what IRC investigative journalists have uncovered on the freenode pedophilia scandal https://encyclopediadramatica.rs/Freenodegate Jul 25 15:11:30 Jul 25 15:11:33 This message was brought to you by Private Internet Access Jul 25 15:12:04 *sigh* fucking spammers Jul 25 15:12:17 zmatt thank you!! im not sure how to see it from current pinmux Jul 25 15:14:15 actually let me back up a step: presumably you have a reason you're suspecting it's not being loaded? Jul 25 15:14:35 its not working kkk Jul 25 15:14:49 is this about a real physical cape with auto-detected overlay, or a custom-configured overlay? Jul 25 15:14:57 also, are you booting from sd card or from eMMC ? Jul 25 15:15:11 a real physical one, im booting from emmc Jul 25 15:15:27 are you using a fairly recent system? Jul 25 15:15:58 DLPDLCR2000 Jul 25 15:16:08 yeah that is part of the trouble i think Jul 25 15:16:10 I mean the linux system Jul 25 15:16:13 cat /etc/dogtag Jul 25 15:16:34 it used to use kernel overlay Jul 25 15:16:55 BeagleBoard.org Debian Image 2018-07-15 Jul 25 15:17:04 okay good Jul 25 15:17:37 if you do: ls /sys/bus/i2c/devices/ Jul 25 15:18:00 does it show a 2-0070 device? Jul 25 15:18:07 i know that i need to set P2_15 to out 1 to turn the device on Jul 25 15:18:33 yeah Jul 25 15:18:47 "P2" ? that makes no sense Jul 25 15:18:50 P2 is the jtag header Jul 25 15:19:00 P9_15 Jul 25 15:19:04 sorry Jul 25 15:19:09 okay it sounds like the overlay is loaded then Jul 25 15:19:50 as a double-check: does /proc/devicetree/panel exist? Jul 25 15:20:01 sorry, /proc/device-tree/panel Jul 25 15:20:06 yeah Jul 25 15:20:15 the overlay is definitely loaded Jul 25 15:21:21 maybe just to be on the safe side, uncomment disable_uboot_overlay_video=1 Jul 25 15:21:24 in /boot/uEnv.txt Jul 25 15:21:35 (to disable hdmi-video) Jul 25 15:21:59 but /proc/device-tree/ocp/P9_15_pinmux doesnt show up Jul 25 15:22:12 aah cool Jul 25 15:24:45 that *is* weird Jul 25 15:25:18 although the overlay disables that node, that shouldn't prevent it from showing up in /proc/device-tree as far as I understand Jul 25 15:26:19 okay this is weird Jul 25 15:26:35 i tried disabling the video and am rebooting to see if that could be it Jul 25 15:26:50 it configures P9.15 and P8.26 to gpio mode, but doesn't reference these gpios anywhere in the overlay Jul 25 15:27:30 it is not that well made i think Jul 25 15:28:37 evidently Jul 25 15:30:00 it is showing up now Jul 25 15:30:24 but if i try to set it manually trough echo 48 > /sys/class/gpio/export Jul 25 15:30:34 then setting it to out and 1 Jul 25 15:30:41 it continues as disabled Jul 25 15:31:36 maybe try double-checking the pinmux using my show-pins utility: https://github.com/mvduin/bbb-pin-utils/#show-pins Jul 25 15:31:45 and check kernel log for errors Jul 25 15:34:29 very cool your utility! Jul 25 15:34:39 it seems like all is correct Jul 25 15:34:57 just the device doesnt live Jul 25 15:35:11 i think it could be something else so Jul 25 15:35:39 P9.15 16 fast 7 gpio 1.16 hi >> sysfs (pinmux_dlp_gpio_pins) Jul 25 15:37:11 How do I connect bipolar stepper motor to BB Blue? Do I just need to use two motor drivers, and Is there any example code for testing with this motor? Jul 25 15:41:41 do you know what could i do to further debug this stuff? Jul 25 16:03:28 Hey, I thought you guys might be interested in this blog by freenode staff member Bryan 'kloeri' Ostergaard https://bryanostergaard.com/ Jul 25 16:09:20 but cat /proc/device-tree/ocp/P9_15_pinmux/status returns disabled, is this right? Jul 25 16:13:42 greboide: the overlay configures that yes Jul 25 16:14:02 https://github.com/beagleboard/bb.org-overlays/blob/master/src/arm/DLPDLCR2000-00A0.dts#L103 Jul 25 16:14:08 since it configures them fixed to gpio Jul 25 16:14:23 (but subsequently doesn't do anything with those gpios bizarrely) Jul 25 16:35:47 zmatt thank you Jul 25 16:36:09 if you have any idea of what i could do plz tell Jul 25 16:36:27 Hey, I thought you guys might be interested in this blog by freenode staff member Bryan 'kloeri' Ostergaard https://bryanostergaard.com/ Jul 25 16:36:27 or maybe this blog by freenode staff member Matthew 'mst' Trout https://MattSTrout.com/ Jul 25 16:36:27 Read what IRC investigative journalists have uncovered on the freenode pedophilia scandal https://encyclopediadramatica.rs/Freenodegate Jul 25 16:36:30 Jul 25 16:36:33 This message was brought to you by Private Internet Access Jul 25 16:44:05 Hey, I thought you guys might be interested in this blog by freenode staff member Bryan 'kloeri' Ostergaard https://bryanostergaard.com/ Jul 25 16:44:08 or maybe this blog by freenode staff member Matthew 'mst' Trout https://MattSTrout.com/ Jul 25 16:44:12 Read what IRC investigative journalists have uncovered on the freenode pedophilia scandal https://encyclopediadramatica.rs/Freenodegate Jul 25 16:44:15 Jul 25 16:44:18 This message was brought to you by Private Internet Access Jul 25 17:13:28 Hey, I thought you guys might be interested in this blog by freenode staff member Bryan 'kloeri' Ostergaard https://bryanostergaard.com/ Jul 25 17:13:28 or maybe this blog by freenode staff member Matthew 'mst' Trout https://MattSTrout.com/ Jul 25 17:13:28 Read what IRC investigative journalists have uncovered on the freenode pedophilia scandal https://encyclopediadramatica.rs/Freenodegate Jul 25 17:13:31 Jul 25 17:13:34 This message was brought to you by Private Internet Access Jul 25 17:32:58 Hey, I thought you guys might be interested in this blog by freenode staff member Bryan 'kloeri' Ostergaard https://bryanostergaard.com/ Jul 25 17:32:58 or maybe this blog by freenode staff member Matthew 'mst' Trout https://MattSTrout.com/ Jul 25 17:32:58 Read what IRC investigative journalists have uncovered on the freenode pedophilia scandal https://encyclopediadramatica.rs/Freenodegate Jul 25 17:33:01 Jul 25 17:33:04 This message was brought to you by Private Internet Access Jul 25 17:33:37 Hey, I thought you guys might be interested in this blog by freenode staff member Bryan 'kloeri' Ostergaard https://bryanostergaard.com/ Jul 25 17:33:40 or maybe this blog by freenode staff member Matthew 'mst' Trout https://MattSTrout.com/ Jul 25 17:33:44 Read what IRC investigative journalists have uncovered on the freenode pedophilia scandal https://encyclopediadramatica.rs/Freenodegate Jul 25 17:33:47 Jul 25 17:33:49 This message was brought to you by Private Internet Access Jul 25 17:56:54 Hey, I thought you guys might be interested in this blog by freenode staff member Bryan 'kloeri' Ostergaard https://bryanostergaard.com/ Jul 25 17:57:33 looks like they're finally doing some spam control Jul 25 18:01:58 zmatt, what the hell is that crap?

Jul 25 18:05:02 so yeah, they got me Jul 25 18:43:10 Hey, I thought you guys might be interested in this blog by freenode staff member Bryan 'kloeri' Ostergaard https://bryanostergaard.com/ Jul 25 18:43:10 or maybe this blog by freenode staff member Matthew 'mst' Trout https://MattSTrout.com/ Jul 25 18:43:18 Read what IRC investigative journalists have uncovered on the freenode pedophilia scandal https://encyclopediadramatica.rs/Freenodegate Jul 25 18:43:19 Jul 25 18:43:19 This message was brought to you by Private Internet Access Jul 25 18:48:11 Hey, I thought you guys might be interested in this blog by freenode staff member Bryan 'kloeri' Ostergaard https://bryanostergaard.com/ Jul 25 18:48:11 or maybe this blog by freenode staff member Matthew 'mst' Trout https://MattSTrout.com/ Jul 25 18:48:11 Read what IRC investigative journalists have uncovered on the freenode pedophilia scandal https://encyclopediadramatica.rs/Freenodegate Jul 25 18:48:14 Jul 25 18:48:16 This message was brought to you by Private Internet Access Jul 25 18:53:42 Hey, I thought you guys might be interested in this blog by freenode staff member Bryan 'kloeri' Ostergaard https://bryanostergaard.com/ Jul 25 18:53:45 or maybe this blog by freenode staff member Matthew 'mst' Trout https://MattSTrout.com/ Jul 25 18:53:49 Read what IRC investigative journalists have uncovered on the freenode pedophilia scandal https://encyclopediadramatica.rs/Freenodegate Jul 25 18:53:52 Jul 25 18:53:55 This message was brought to you by Private Internet Access Jul 25 19:01:55 Hey, I thought you guys might be interested in this blog by freenode staff member Bryan 'kloeri' Ostergaard https://bryanostergaard.com/ Jul 25 19:01:58 or maybe this blog by freenode staff member Matthew 'mst' Trout https://MattSTrout.com/ Jul 25 19:02:02 Read what IRC investigative journalists have uncovered on the freenode pedophilia scandal https://encyclopediadramatica.rs/Freenodegate Jul 25 19:02:05 Jul 25 19:02:08 This message was brought to you by Private Internet Access Jul 25 19:05:39 __av500__: jkridner: LetoThe2nd: can't we add an auto-ban on the first line of this spam or something? Jul 25 19:06:54 Hey, I thought you guys might be interested in this blog by freenode staff member Bryan 'kloeri' Ostergaard https://bryanostergaard.com/ Jul 25 19:13:59 ugh. Jul 25 19:14:09 do you know the IRC magic foo? Jul 25 19:16:17 jkridner / zmatt - "sigyn" is already taking care of that on a network level. what you see is the latency between the line entering the network and sigyn killing off the client Jul 25 19:16:26 okay Jul 25 19:16:58 then a bot wouldn't be able to do any good either Jul 25 19:18:20 jkridner: as we have "guest" traffic we don't have many options. could set "+q $~a" but that would mute everyone who's not authenticated against nickserv. Dunno if you can exempt *!*@gateway/web/freenode/* with an additional line Jul 25 19:19:04 tbr: not sure what is reasonable. Jul 25 19:19:14 tbr: I want newbs to be able to join. :-( Jul 25 19:19:38 http://freenode.net/kb/answer/channelmodes Jul 25 19:20:25 "Ban exemption matches override +b and +q " Jul 25 19:21:01 is a join throttle a good thing? Jul 25 19:21:09 so you could add a "+e *!*@gateway/web/freenode/*" line to relax "+q $~a" Jul 25 19:21:40 but, that only allows people in from the web interface... Jul 25 19:21:46 and maybe a +z, but that would require chanops to be around Jul 25 19:21:59 I guess that's where most newbs arrive, but what happens to those on other clients? Jul 25 19:22:08 jkridner: rationale, if you know how to start an IRC client, you should be able to figure out nickserv Jul 25 19:22:34 I guess +z would allow others to enter, but I'd need come chanops to be notified. Jul 25 19:22:36 jkridner: IIRC nickserv or chanserv will message you and tell you that you are muted Jul 25 19:22:45 zmatt: what do you think? Jul 25 19:22:55 tbr: what would be the equivalent for riot.im? Jul 25 19:22:58 +q allows people to enter, but they can't say anything Jul 25 19:23:08 gateway/shell/matrix.org Jul 25 19:23:20 *!*@gateway/shell/matrix.org ? Jul 25 19:23:52 *!*@@gateway/web/irccloud.com/* Jul 25 19:23:55 so, I prefix each of those with /mode #beagle ? Jul 25 19:24:00 *!*@gateway/shell/matrix.org* actually Jul 25 19:24:10 just in here type: Jul 25 19:24:23 and individuals could still be kicked/banned on those channels? Jul 25 19:24:26 er, gateways Jul 25 19:24:26 /mode +e *!*@gateway/shell/matrix.org* Jul 25 19:24:48 unless you have chanserv enforcing modes Jul 25 19:25:31 /mode +ee *!*@@gateway/web/irccloud.com/* *!*@gateway/web/freenode/* Jul 25 19:25:39 ee? Jul 25 19:25:49 means two modes Jul 25 19:25:57 as that line contains two host masks Jul 25 19:25:59 k, well I've set those modes now. Jul 25 19:26:31 did you set +q $~a Jul 25 19:26:58 not yet... Jul 25 19:27:10 /mode +z doesn't seem to take Jul 25 19:28:13 k, I've now quieted all those w/o nickserv and not on those gateways. Jul 25 19:28:16 yup, that line didn't make it through from tbr-test Jul 25 19:28:28 tbr-test: hmmm... came through to me. Jul 25 19:28:48 zmatt: can you see what tbr-test said? Jul 25 19:30:14 I wonder if chanop is too generic. Jul 25 19:30:32 jkridner: actually "please authenticate with nickserv" Jul 25 19:30:37 really, jkridner[m] gets my attention best due to the app. Jul 25 19:34:36 zmatt: when back, please let me know. Jul 25 19:34:50 back Jul 25 19:34:56 I didn't see tbr-test Jul 25 19:35:41 http://logs.nslu2-linux.org/livelogs/beagle.txt looks clean... Jul 25 19:35:52 just figured I could use that. Jul 25 19:36:13 k. if traffic dies down way too much, let me know. Jul 25 19:36:47 random people on the webclient can still post. Jul 25 19:37:23 grrr. rc_test_imu Jul 25 19:37:29 but... are you *truly* random? Jul 25 19:37:37 as can folks from riot.im Jul 25 19:37:54 never truly random, but i try. Jul 25 19:38:14 /nick 9 Jul 25 19:38:15 http://dilbert.com/strip/2001-10-25 Jul 25 19:38:35 reasonably unpredictable Jul 25 20:12:23 Can I connect a stepper motor to the built-in motor driver tb6612fng on BB Blue? if so how? Jul 25 20:13:52 (bipolar stepper) Jul 26 00:11:34 doh Jul 26 00:12:02 oh, maybe I'm the only one that sees ruunyan17 just ^^^? Jul 26 00:12:18 yup Jul 26 00:12:31 sweet. Jul 26 00:12:43 otherwise, we'd've just got another huge batch of spam. Jul 26 00:13:15 fe35w: you'd use a 4-wire stepper and you'd have to alternate the drive of each of the motors. Jul 26 00:13:39 you'd use a pair of the 2-wire motor drivers to connect the 4-wire stepper. Jul 26 00:14:37 right, so i would have to use M1 and M2 for instance. one for each coil in the motor Jul 26 00:14:51 In my code, I would just have to alternate turning one off and the other on? Jul 26 00:14:52 fe35w: exactly. Jul 26 00:14:56 fe35w: yes. Jul 26 00:15:17 Thanks. Are there any example codes you know of? Jul 26 00:15:33 fe35w: I eventually plan to get some PRU code to do stepping for you as well as some microstepping, but none of it is written yet. Jul 26 00:15:45 no, but I could probably throw some together. Jul 26 00:16:25 That would be great Jul 26 00:16:32 I know I have a stepper around here somewhere. Jul 26 00:16:35 Just to see the basic commands necessary to operate Jul 26 00:17:00 fe35w: you comfortable with C? Jul 26 00:17:25 Sure, C and Python are both fine Jul 26 00:19:39 well, won't happen today. I'll look for a stepper tonight and take a stab at it tomorrow. Jul 26 00:22:06 Thanks! Would it be posted on github if you figured it out? Jul 26 00:26:55 yes and Blue wiki. **** ENDING LOGGING AT Thu Jul 26 03:00:01 2018
