Jan 28 08:48:17 <jediMind> Hello all
Jan 28 08:48:27 <jediMind> Where can I find peripheral drivers for the beagle bone blue??
Jan 28 08:48:34 <Humpelstilzchen> To use the overlays from https://github.com/beagleboard/bb.org-overlays - which kernel should I compile?
Jan 28 08:48:43 <Guest81141> like for th eIMU, pressure sensor, pwm (using PRU) etc
Jan 28 10:38:45 <Alkabal> Hi all, do you know if this is possible to use BeagleBoard Blue with machinekit and use stepper motor driver (leadshine dm556) ?
Jan 28 10:40:20 <kremlin> i don't know what machinekit is but i know that you can use the BBB to control stepper motors
Jan 28 10:48:04 <Alkabal> machinekit is linuxcnc for ARM
Jan 28 10:48:36 <Alkabal> i know for the BB-black that can driver stepper
Jan 28 10:48:57 <Alkabal> question is for new Blue version
Jan 28 10:50:26 <kremlin> oh, i dont know about that
Jan 28 10:50:37 <Alkabal> https://beagleboard.org/blue
Jan 28 10:51:01 <kremlin> yeah, i don't know if it can do it or not
Jan 28 10:51:04 <Alkabal> they only write about other type of motor
Jan 28 10:51:06 <Alkabal> Motor control: 8 6V servo out, 4 DC motor out,
Jan 28 10:51:28 <Alkabal> thanks for reply
Jan 28 10:51:55 <kremlin> you're welcome
Jan 28 10:57:07 <jues> Hi there. Anyone with a Beaglebone Balck Wireless here?
Jan 28 11:34:23 <Shatodor> Hello! What does this means "fsck: error 2 (No such file or directory) while executing fsck.ext4 for /dev/mmcblk1p1 fsck exited with status code 8"?
Jan 28 11:34:49 <kremlin> post your specific invocation
Jan 28 11:35:19 <kremlin> you probably passed a device that doesn't exist
Jan 28 11:35:30 <kremlin> that makes fsck bomb out for me with errno 8
Jan 28 11:46:38 <Shatodor> What is "invocation"?
Jan 28 11:47:24 <tbr> the exact command that you attempted
Jan 28 11:48:26 <Shatodor> It shows during boot process
Jan 28 11:50:02 <zmatt> sounds like fsck.ext4 managed to not get included in the initramfs somehow?
Jan 28 11:50:23 <zmatt> maybe
Jan 28 11:50:39 <tbr> which distro/version is this anyway?
Jan 28 11:52:32 <Shatodor> BBB-blank-debian-8.10-lxqt-2gb-armhf-2018-01-01-2gb.img.xz
Jan 28 11:53:22 <Shatodor> BeagleBone Black rev 00C0
Jan 28 11:53:46 <zmatt> still using jessie (debian 8) instead of stretch (debian 9) ? why?
Jan 28 11:58:01 <Shatodor> I somehow corrupted preinstaled vesrion of debian and found only this version wich has eMMC auto flasher/
Jan 28 12:12:38 <zmatt> there are instructions below the download links at bbb.io/latest-images on how to turn an image into a flasher, also you can get prebuilt flashers at https://elinux.org/Beagleboard:BeagleBoneBlack_Debian
Jan 28 12:13:28 <zmatt> get stretch-lxqt if you really want a desktop environment (gui), otherwise stretch-iot if you just use ssh, cloud9, etc
Jan 28 12:21:01 <Shatodor> Thanks, I will try to do it.
Jan 28 12:28:46 <Shatodor> What password is for sudo in latest versions of debian?
Jan 28 12:28:46 <zmatt> although I still wonder what the hell happened to the system you had, but I'm not in the mood for remote debugging weird boot issues
Jan 28 12:29:18 <zmatt> sudo asks for the password of the account you're on, i.e. temppwd
Jan 28 12:29:32 <zmatt> (by default)
Jan 28 14:17:17 <Shatodor> I connected to BB desktop through VNC. Trying to use terminal but keybord typing random characters. Why is that?
Jan 28 14:51:51 <tbr> I personally would not want to run a graphical environment on the BBB, especially not to run a terminal
Jan 28 14:57:59 <zmatt> sounds weird, but why are you using a terminal via vnc instead of ssh?
Jan 28 14:58:43 <Shatodor> I trying to test OpenCV.
Jan 28 14:59:51 <Shatodor> and webcam.
Jan 28 15:03:53 <tbr> there won't be many cycles left with the desktop and vnc being busy
Jan 28 15:04:28 <zmatt> and usb
Jan 28 15:06:41 <Shatodor> So what should i do?
Jan 28 15:11:23 <zmatt> if you really need video output (to monitor the cam or some sort of graphical output from opencv) then connect a hdmi monitor
Jan 28 15:11:48 <zmatt> otherwise just stick to ssh
Jan 28 15:16:08 <Shatodor> Ok, thanks. Maybe you can also recommend sources describing using openCV with BBB in C/C++?
Jan 28 15:17:23 <zmatt> I have no idea, I don't have any experience with it
Jan 28 15:18:12 <zmatt> opencv potentially sounds a bit heavy for the bbb? I guess it depends
Jan 28 15:18:52 <zmatt> hopefully it makes good use of Neon
Jan 28 15:50:01 <jediMindTricks> hello all
Jan 28 15:50:12 * myself is not the pronoun you're looking for
Jan 28 15:50:50 <jediMindTricks> please tell me where I can find peripheral libraries for the BeagleBone Blue
Jan 28 15:50:57 <jediMindTricks> Also, for the PRU
Jan 28 15:51:15 <myself> Oh man. the Blue needs a support group.
Jan 28 15:51:32 <myself> And I don't mean like a page of resources. I mean like an emotional everyone-cry-together club.
Jan 28 15:51:44 <myself> although a page of resources would be great too.
Jan 28 15:51:49 <tbr> I haven't seen any proper documentation on the blue, last time I checked.
Jan 28 15:52:23 <myself> If only we could get everyone who asks this question to *stay in the channel* long enough to meet each other and start assembling such documentation
Jan 28 15:52:31 <jediMindTricks> well..?
Jan 28 15:54:28 <myself> This is a good start: https://github.com/beagleboard/beaglebone-blue/wiki/Accessories
Jan 28 15:54:34 <myself> hit all the links down the right side ofthe page
Jan 28 15:56:52 <tbr> myself: h(a)unting jkridner[m] would be a good idea too
Jan 28 15:57:34 * tbr still doesn't see a SRM
Jan 28 15:58:04 <myself> As I understand it, the Blue is just a Black with a Robotics Cape mushed into it, to a first approximation. Some stuff about power is different but only a little.
Jan 28 15:58:13 <myself> So all the Robotics Cape docs should apply.
Jan 28 15:58:32 <jediMindTricks> page*
Jan 28 15:58:40 <jediMindTricks> I can't use that library
Jan 28 15:58:57 <jediMindTricks> that mage is for the devices right??
Jan 28 15:59:01 <jediMindTricks> My question is
Jan 28 15:59:01 <jediMindTricks> so
Jan 28 15:59:10 <myself> backwards?
Jan 28 15:59:12 <myself> do you always talk
Jan 28 15:59:15 <jediMindTricks> afaik i can user any mpu9250 driver right
Jan 28 15:59:30 <jediMindTricks> how do i find out which i2c pins the emu etc are connected to
Jan 28 16:00:05 <jediMindTricks> imu*
Jan 28 16:00:56 <zmatt> presumably the imu is already declared in DT and usable
Jan 28 16:01:13 <zmatt> check /sys/bus/iio/devices
Jan 28 16:02:14 <jediMindTricks> bio:device0
Jan 28 16:02:16 <jediMindTricks> iio*
Jan 28 16:02:46 <zmatt> hm, that's probably the adc, so I guess they didn't declare the devices in DT
Jan 28 16:02:47 <zmatt> I dunno
Jan 28 16:02:50 <zmatt> I don't have a blue
Jan 28 16:03:19 <jediMindTricks> what is pruspeak
Jan 28 16:05:54 <jediMindTricks> tbh I don't see how you can have robots. faster. with the blue
Jan 28 16:06:29 <jediMindTricks> its been a horrible experience for me so far
Jan 28 16:06:50 <zmatt> sorry to hear that
Jan 28 16:06:53 <jediMindTricks> Mainly because I am not a embedded programmer
Jan 28 16:07:00 <jediMindTricks> But isn't that a point about the blue?
Jan 28 16:07:03 <jediMindTricks> anyway
Jan 28 16:07:27 <jediMindTricks> Is pruspeak a library?
Jan 28 16:07:51 <myself> I don't think it's meant to be a lego kit... it's a board for embedded programmers to save time vs spinning their own board
Jan 28 16:08:42 <myself> first sentence of the first page when I google "pruspeak" says: PRU Speak is an implementation of the BotSpeak language for the PRU.
Jan 28 17:59:36 <dhruvlaad> Hello all, I run i2cdetect on the blue to see where imu device is, but how can i find which i2c bus/pins its connected to?
Jan 28 18:02:02 <dhruvlaad> hello is anyone there?
Jan 28 18:05:59 <dhruvlaad> like I know its on I2C_SDA/SCL
Jan 28 18:06:13 <dhruvlaad> but
Jan 28 18:06:34 <dhruvlaad> I have a mpu9250 library written in C that i need to use, which requires the I2C pins as an argument
Jan 28 18:06:41 <dhruvlaad> so what do I enter here?
Jan 28 18:12:45 <myself> which type of pin designator does it want? the package ball? the register address? the linux device node?
Jan 28 18:14:24 <myself> I'm pretty sure there's a spreadsheet around that gives all the pins and how they're named, but I just lost my scrollback and don't have the link handy.
Jan 28 18:14:50 <myself> that would be a nice thing to have in the /topic instead of the broken links that're there now :P
Jan 28 18:15:55 <dhruvlaad> I have a very new question,
Jan 28 18:15:56 <dhruvlaad> newb*
Jan 28 18:16:20 <dhruvlaad> are there i2c drivers available for the blue? won't i2c drives made for the black work just as well?
Jan 28 18:16:39 <myself> As far as I know, the blue _is_ a black with a cape on top of it
Jan 28 18:16:46 <myself> to a first approximation
Jan 28 18:16:53 <myself> so yes, try that
Jan 28 19:18:07 <zmatt> myself: which they seem to work fine for me
Jan 28 19:18:09 <zmatt> the links
Jan 28 19:19:30 <zmatt> and yeah the blue is more-or-less a beaglebone black wireless + robotics cape (+ some stuff)
Jan 28 20:09:16 <myself> Huh. https://beagleboard.org/start for me loads a blank page with just a last-edited-by date.
Jan 28 20:10:11 <zmatt> it redirects to https://beagleboard.org/getting-started for me
Jan 28 20:11:08 <myself> interesting!
Jan 28 20:13:26 <myself> I'm on firefox 58 on ubuntu, no add-ons
