Mar 31 20:09:14 <vantomcat> Hi folks! I am struggling with DHT11 on bb green + grove cape, sensor is seeed grove. Need help in debugging. I suspect cape may not be enabled or something gpio wise...
Mar 31 20:09:41 <vantomcat> Can't get any readings... very frustrating
Mar 31 20:11:16 <vantomcat> I tried several different libs, attached sensor to different ports, installed latest Linux but nothing really works
Mar 31 20:32:12 <zmatt> vantomcat: hmm, DHT11 is the annoying one-wire protocol right?
Mar 31 20:34:57 <zmatt> it'll be very tricky to get reliable readings using userspace code, since it would require gpios to be controlled with precise timing
Mar 31 20:35:48 <zmatt> iirc there's also a kernel driver, but that would need to be enabled using an overlay (and you'd lose cape-universal as a consequence)
Mar 31 20:36:54 <zmatt> the code I can find seems to use /dev/mem to directly manipulate the gpio (which is kinda icky and unsafe)
Mar 31 20:37:15 <zmatt> presumably since the sysfs interface has too much overhead
Mar 31 20:38:55 <zmatt> the most elegant solution would probably be to use PRU for it, but I'm not sure if you can find a simple "plug & play" example for that
Mar 31 20:39:52 <zmatt> really, the big question is: why the fuck doesn't that stupid sensor use i2c ? :P
Mar 31 20:40:52 <zmatt> oh, he left at some point
Mar 31 20:40:53 <zmatt> damnit
Mar 31 20:41:18 <zmatt> well, for the irc logs I guess :P
Mar 31 23:59:28 <fortnight> hello...
Mar 31 23:59:45 <FL4SHK> Helo
Mar 31 23:59:57 <fortnight> Hey...what are you doing w/ your BBB/etc?
Apr 01 00:00:29 <FL4SHK> I've got ALARM On it.  I wish to get X11 working.
Apr 01 00:00:51 <fortnight> Alarm! Cool...
Apr 01 00:01:07 <fortnight> Your x11 does not work (Debian)?
Apr 01 00:01:14 <FL4SHK> Oh, excuse me, Arch Linux ARM
Apr 01 00:01:21 <fortnight> Oh.
Apr 01 00:01:22 <FL4SHK> That's what I meant by "ALARM".
Apr 01 00:01:29 <fortnight> Aw!
Apr 01 00:01:42 <fortnight> I use Debian mostly.
Apr 01 00:01:45 <fortnight> Sorry mate.
Apr 01 00:01:53 <FL4SHK> Oh, no problem.
Apr 01 00:02:03 <fortnight> Wait around. I am sure someone will see the post.
Apr 01 00:02:08 <FL4SHK> Oh, no problem.
Apr 01 00:02:20 <FL4SHK> I get the feeling I installed the wrong libgl.
Apr 01 00:02:37 <fortnight> Oh. Are you cross-compiling?
Apr 01 00:03:00 <FL4SHK> Nah, don't have to do that.  Arch Linux ARM is mainly a binary distro.
Apr 01 00:03:06 <fortnight> Oh!
Apr 01 00:03:11 <FL4SHK> However I noticed that the BBB is quite fast even if you do have to compile stuff.
Apr 01 00:03:43 <fortnight> If you use it as a target board, yes. But not w/ the compiling of source.
Apr 01 00:04:05 <FL4SHK> Well I guess it was only some small packages I compiled.
Apr 01 00:04:17 <fortnight> Oh. That should be fine.
Apr 01 00:04:26 <fortnight> Hey...give me a link. Maybe I can help.
Apr 01 00:04:41 <FL4SHK> A link?
Apr 01 00:04:51 <FL4SHK> https://archlinuxarm.org/platforms/armv7/ti/beaglebone-black
Apr 01 00:04:57 <fortnight> Yea. For what Distro you are putting on your board.
Apr 01 00:05:00 <fortnight> Oh...okay.
Apr 01 00:05:12 <FL4SHK> I have got the distro up and running, mind you.
Apr 01 00:05:37 <fortnight> Aw...what is the issue. No OS?
Apr 01 00:05:57 <FL4SHK> Oh, no, that's not the problem.  I have the thing booted.  I just ran into an X11 error when I tried to run startx.
Apr 01 00:06:05 <fortnight> eMMC or SD Card?
Apr 01 00:06:09 <FL4SHK> SD Car
Apr 01 00:06:12 <FL4SHK> d
Apr 01 00:06:23 <FL4SHK> I decided to just use the SD card for booting because much more space
Apr 01 00:06:35 <fortnight> This is cool. I have not seen this site before.
Apr 01 00:06:44 <fortnight> They have some nice info.
Apr 01 00:06:50 <FL4SHK> Oh, yes, they have builds for a lot of ARM boards.
Apr 01 00:07:17 <fortnight> I was cross-compiling w/ Ubuntu to the BBB. I use crosstools-ng for now.
Apr 01 00:07:34 <fortnight> FL4SHK: Let me read some and I will get right back to you.
Apr 01 00:07:50 <FL4SHK> Alright
Apr 01 00:10:49 <fortnight> I am learning about startx right now. I was unaware of this program (for many reasons).
Apr 01 00:10:56 <FL4SHK> Oh, right
Apr 01 00:11:00 <FL4SHK> startx isn't the problem, mind you
Apr 01 00:11:05 <fortnight> Oh.
Apr 01 00:11:11 <FL4SHK> It's X itself having issues :P
Apr 01 00:11:39 <fortnight> Hmm. So, the Distro is giving feedback issues, i.e. negative feedback.
Apr 01 00:11:46 <FL4SHK> Well
Apr 01 00:11:49 <fortnight> Pastebin!
Apr 01 00:12:07 <fortnight> Well what/
Apr 01 00:12:27 <fortnight> I know. It is complicated.
Apr 01 00:13:16 <FL4SHK> I think I just need to find out what specific packages I need
Apr 01 00:13:38 <fortnight> So...you can sign in, complete cmds, and the system gives your garbage in return once you use the cmd startx?
Apr 01 00:13:50 <FL4SHK> Yes because the X server is failing
Apr 01 00:14:03 <fortnight> WiFi or Ethernet?
Apr 01 00:14:12 <FL4SHK> Ethernet
Apr 01 00:14:26 <fortnight> Can you update and upgrade your system?
Apr 01 00:14:29 <FL4SHK> Yes
Apr 01 00:14:36 <FL4SHK> I mean I'm installing various packages
Apr 01 00:14:44 <fortnight> Okay. I got you.
Apr 01 00:15:08 <FL4SHK> getting "EGL_MESA_drm_image required"
Apr 01 00:15:17 <fortnight> Oh.
Apr 01 00:15:22 <FL4SHK> and "modeset(0): glamor initialization failed"
Apr 01 00:15:40 <fortnight> Did you look up those errors yet?
Apr 01 00:16:04 <fortnight> I can look them up if you have not.
Apr 01 00:16:20 <FL4SHK> Yeah, I've looked them up.
Apr 01 00:16:36 <FL4SHK> I didn't get any useful results.
Apr 01 00:17:01 <fortnight> Okay! So, if you want (still), I will look up what i can find on those specific errors and we can share.
Apr 01 00:17:20 <fortnight> Who knows? We may be able to figure it out.
Apr 01 00:17:35 <FL4SHK> Oh, yeah, that's fine.
Apr 01 00:17:49 <fortnight> Okay. Up, up, and away!
Apr 01 00:17:52 <fortnight> Brb
Apr 01 00:18:02 <FL4SHK> At the very least I could just use X forwarding over SSH if need be, but that's not ideal at all.
Apr 01 00:18:42 <fortnight> You are using a Virtual Box or something?
Apr 01 00:22:06 <fortnight> Do you have the server?
Apr 01 00:22:20 <GigaFL4SHK> Server?
Apr 01 00:22:23 <GigaFL4SHK> oh
Apr 01 00:22:30 <GigaFL4SHK> also brb
Apr 01 00:22:34 <fortnight> Okay.
Apr 01 00:23:31 <fortnight> https://bbs.archlinux.org/viewtopic.php?id=206470 <<<< something interesting I have been reading on this subject.
Apr 01 00:25:10 <fortnight> https://wiki.archlinux.org/index.php/Main_page <<<<< damn! You have all sorts of issues solved for Arch Linux.
Apr 01 00:28:38 <fortnight> FL4SHK: I found something about running things for Archers ----> https://wiki.archlinux.org/index.php/Frequently_asked_questions
Apr 01 00:28:44 <fortnight> ...
Apr 01 00:28:59 <fortnight> Look for starting package X.
Apr 01 00:30:06 <FL4SHK> Yeah, that's not X11, heh.
Apr 01 00:30:12 <FL4SHK> I think I've got the wrong driver of some sort installed.
Apr 01 00:30:26 <fortnight> Sir, do you want a desktop environment or a window manager?
Apr 01 00:30:35 <FL4SHK> I'd be happy getting either of those working.
Apr 01 00:30:43 <fortnight> Okay. Please hold.
Apr 01 00:31:41 <fortnight> What did you install w/ pacman, e.g. gnome, xfce, etc?
Apr 01 00:31:57 <FL4SHK> I installed simply twm.
Apr 01 00:32:07 <fortnight> twm. Okay. Hold again.
Apr 01 00:33:36 <fortnight> Sir, I could not find twm. But I found a ton of stuff on Desk. Env.
Apr 01 00:33:58 <FL4SHK> Oh, well, I think this is an Arch specific problem.
Apr 01 00:34:49 <fortnight> I found LXDE, you can install this w/ https://wiki.archlinux.org/index.php/LXDE.
Apr 01 00:35:43 <FL4SHK> It's not the DE installation that I'm struggling with, mind you.  It's the fact that I can't boot X at all :P
Apr 01 00:36:09 <fortnight> I understand. Maybe it is not installed correctly w/in the arm distro from Arch.
Apr 01 00:36:20 <FL4SHK> That's possible
Apr 01 00:36:36 <FL4SHK> Let me double check the hardware again
Apr 01 00:36:40 <fortnight> Okay.
Apr 01 00:37:28 <FL4SHK> powervr
Apr 01 00:37:41 <fortnight> lxde-common, lxsession, and openbox is needed for LXDE.
Apr 01 00:37:51 <fortnight> powervr is your desktop environment?
Apr 01 00:37:58 <FL4SHK> PowerVR is the hardware
Apr 01 00:38:05 <FL4SHK> sounds like that's the name of the GPU
Apr 01 00:38:29 <FL4SHK> https://archlinuxarm.org/platforms/armv7/ti/beaglebone-black from this page :P
Apr 01 00:39:31 <fortnight> Hacking is not easy. Try the LXDE.
Apr 01 00:40:43 <FL4SHK> Eh, alright.
Apr 01 00:41:07 <fortnight> If not, we can also try others like gnome or xfce.
Apr 01 00:41:15 <fortnight> LXDE is lightweight.
Apr 01 00:41:20 <FL4SHK> I don't think the DE is the issue though.
Apr 01 00:41:25 <fortnight> Oh.
Apr 01 00:41:39 <FL4SHK> Still probably going to use LXDE once all the issues are gone though :P
Apr 01 00:41:47 <fortnight> Okay. So, there is a set up/configuration issue from the past that may be an issue?
Apr 01 00:42:02 <fortnight> ...
Apr 01 00:42:15 <FL4SHK> No, nope, this is a fresh install.
Apr 01 00:42:43 <fortnight> I just do not know everything you are going through on your system. You could have config. issues that have nothing to do w/ what we are discussing.
Apr 01 00:43:07 <FL4SHK> Well, alright, at least we tried :P
Apr 01 00:43:13 <fortnight> HHeh?
Apr 01 00:43:17 <fortnight> Wait.
Apr 01 00:44:05 <fortnight> once in LXDM, your display manager in LXDE, define LXDE in xinitrc.
Apr 01 00:44:10 <FL4SHK> Okay.
Apr 01 00:44:26 <fortnight> so, ~/.xinitrc
Apr 01 00:44:30 <fortnight> then...
Apr 01 00:44:37 <fortnight> exec startlxde
Apr 01 00:45:42 <FL4SHK> "failed to load driver: tilcdc"
Apr 01 00:46:40 <fortnight> Wait...did you install lxde-common, lxsession, and openbox?
Apr 01 00:46:47 <FL4SHK> Yes
Apr 01 00:49:44 <fortnight> Who knows, maybe that LXDE is not available on the Arm Distro. Let me check.
Apr 01 00:49:59 <catchra> hi i just flashed  Debian 9.3 2018-01-28 4GB SD LXQT to my BBBW and i am getting Error wifi: Method "SetProperty" with signature "sv" on interface "net.connman.Technology" doesn't exist
Apr 01 00:51:10 <fortnight> FL4SHK: There are dependencies.
Apr 01 00:52:03 <FL4SHK> LXDE is available.
Apr 01 00:52:15 <FL4SHK> It is definitely the drivers causing me problems.
Apr 01 00:52:18 <FL4SHK> I might as well switch distros.
Apr 01 00:52:42 <fortnight> Look for https://archlinuxarm.org/packages/any/lxde-common. They are optional but may be useful. Oh and sir, use groups.
Apr 01 00:52:58 <FL4SHK> I already have LXDE installed.
Apr 01 00:53:02 <fortnight> I am a newbie w/ groups but it seems like you must have groups enabled (or something  like that).
Apr 01 00:53:54 <fortnight> Let me look up your error.
Apr 01 00:55:24 <fortnight> https://e2e.ti.com/support/arm/sitara_arm/f/791/p/610110/2246324. It states you need both LXDE and gtk3.
Apr 01 00:55:34 <fortnight> Install gtk3. That should work.
Apr 01 00:57:55 <FL4SHK> already got it
Apr 01 00:58:00 <fortnight> Hmmm.
Apr 01 00:58:11 <fortnight> The damn instructions state what the instructions state.
Apr 01 00:58:18 <fortnight> I am beat. Please hold.
Apr 01 00:58:22 <FL4SHK> No, that's alright
Apr 01 00:58:27 <FL4SHK> I think it's a drivers issue.
Apr 01 00:58:29 <fortnight> Hahahah.
Apr 01 00:58:30 <fortnight> Okay.
Apr 01 00:59:08 <fortnight> https://archlinuxarm.org/forum/viewtopic.php?f=28&t=5780 <----- BBB stuff!
Apr 01 01:00:28 <FL4SHK> oh apparently there's just an Xorg config thing.
Apr 01 01:00:32 <FL4SHK> time to get ahold of that.
Apr 01 01:00:38 <fortnight> Hey...do you have a cape?
Apr 01 01:00:50 <FL4SHK> Not yet.
Apr 01 01:00:59 <fortnight> So, just a usb to monitor/computer?
Apr 01 01:01:00 <FL4SHK> I have ideas for things to do with this thing.
Apr 01 01:01:04 <fortnight> Okay.
Apr 01 01:01:06 <kremlin> use the pru
Apr 01 01:01:06 <FL4SHK> actually microHDMI
Apr 01 01:01:11 <fortnight> Oh. Okay.
Apr 01 01:01:16 <FL4SHK> the PRU interests me as well
Apr 01 01:01:20 <fortnight> Me too.
Apr 01 01:01:26 <fortnight> Fast!
Apr 01 01:01:32 <FL4SHK> I'll have to look at the instruction set for that thing.
Apr 01 01:02:04 <fortnight> I was reading. I found a ton of resources. I will understand if you want to discuss this issue w/ other people.
Apr 01 01:02:31 <FL4SHK> Yeah, I think that thing you posted will work.
Apr 01 01:02:36 <FL4SHK> I bet that 10-screen.conf will work.
Apr 01 01:02:47 <fortnight> It seems like they "solved" it.
Apr 01 01:02:56 <fortnight> Maybe that last link will help.
Apr 01 01:04:30 <fortnight> ...
Apr 01 01:04:48 <fortnight> If all else fails, I can set up the system on my BBB and try. I would have to get back to you, though.
Apr 01 01:06:48 <FL4SHK> yes so that last link got it
Apr 01 01:06:50 <FL4SHK> I am now in.
Apr 01 01:06:52 <FL4SHK> Woo
Apr 01 01:06:56 <FL4SHK> excellent.
Apr 01 01:07:31 <FL4SHK> https://archlinuxarm.org/forum/viewtopic.php?f=28&t=5780 last post on this page
Apr 01 01:10:04 <fortnight> Yep.
Apr 01 01:10:06 <fortnight> Cool.
Apr 01 01:10:12 <fortnight> What next?
Apr 01 01:11:54 <fortnight> Hey man...I am sorry to send you for a loop but I only know so much about that issue from what I read. I guess, since it worked, we are even.
Apr 01 01:12:11 <fortnight> loop = answer
Apr 01 01:17:19 <FL4SHK> Yeah it was a simple fix.
Apr 01 01:17:26 <FL4SHK> I probably don't have OpenGL acceleration here.
Apr 01 01:17:32 <FL4SHK> I'm gonna want to set up a VNC session
Apr 01 01:17:36 <FL4SHK> And then use a mouse via that.
Apr 01 01:17:44 <FL4SHK> Since my USB hub appears to be dead, heh.
Apr 01 01:18:01 <FL4SHK> oh wait
Apr 01 01:18:06 <FL4SHK> no, it's just not powered well enough.
Apr 01 01:18:08 <FL4SHK> That explains it
Apr 01 01:18:24 <fortnight> Oh.
Apr 01 01:18:42 <fortnight> Hmmm.
Apr 01 01:18:58 <fortnight> Damn hubs suck. I used to use them.
Apr 01 01:19:36 <FL4SHK> I didn't give it a high enough voltage.
Apr 01 01:19:43 <FL4SHK> it wanted 7.5V, but I gave it 5.0V
Apr 01 01:19:52 <fortnight> Oops.
Apr 01 01:21:23 <fortnight> Hey.
Apr 01 01:21:43 <fortnight> You can type tightvnc and get online that way w/ a GUI.
Apr 01 01:22:07 <FL4SHK> Yes
Apr 01 01:22:21 <fortnight> just remember to use the :1 or whatever number you are using to use vnc viewer.
Apr 01 01:22:26 <FL4SHK> ye
Apr 01 01:23:06 <fortnight> I had some trouble a while back and found my vnc viewer did not work but it was b/c of the number, e.g. 192.168.7.2:1 and I needed :2 instead.
Apr 01 01:23:26 <FL4SHK> I've got ethernet set up.
Apr 01 01:23:32 <fortnight> Cool beans!
Apr 01 01:26:39 <fortnight> small details. Shessh.
Apr 01 01:32:50 <fortnight> My desktop env. is acting up. I have as gray screen w/ odd values posted when I type in the terminal.
Apr 01 01:33:04 <fortnight> My distro works but not LXDE.
Apr 01 01:33:35 <FL4SHK> oh
Apr 01 01:33:43 <fortnight> I know. Odd days.
Apr 01 01:33:53 <fortnight> It is no issue though. I do not use it all that much.
Apr 01 01:34:08 <fortnight> Actually never. I just like to test it out every now and then.
Apr 01 01:35:03 <fortnight> Hey FL4SHK: Does your DE work well?
Apr 01 01:35:15 <FL4SHK> I just wanted to get X working as a whole
Apr 01 01:35:38 <fortnight> Oh...okay.
Apr 01 01:35:49 <fortnight> So, does it?
Apr 01 01:37:38 <FL4SHK> I haven't tested it yet.  Saving that for tomorrow possibly.
Apr 01 01:37:54 <fortnight> Oh.
Apr 01 01:38:14 <FL4SHK> Reason for that is that I'm getting off the computer for the night.
Apr 01 01:38:23 <fortnight> Okay. I guess if nothing is working then (tomorrow), you can always come back and ask away.
Apr 01 01:38:30 <FL4SHK> I'm sure it'll work.
Apr 01 01:38:48 <fortnight> There are more intelligent people here w/ more info. than I.
Apr 01 01:38:56 <fortnight> Good luck!
Apr 01 01:39:28 <FL4SHK> Thank
