**** BEGIN LOGGING AT Sun Apr 28 02:59:57 2019
Apr 28 07:26:24 <Simons> Anybody use BBB for Serial communications.  I can easily get UART Pins configured and tested with MiniComm and screen /dev/ttyO1.  When I use OpenSerial() in bone, I get an Error "err":"Kernel does not include CapeMgr module".
Apr 28 07:27:59 <Simons> I have read many message boards, tried several Debian versions, several get-installs, even tried python for a bit.
Apr 28 08:08:25 <tbr> Simons: sounds like it's trying to use the old capemanager to control pinmux and such
Apr 28 08:09:09 <tbr> Simons: if you set up pinmux externally, then you could just short out that logic or just straight use the serial device without that library
Apr 28 14:25:54 <CoffeeBreakfast> Hello all. Suppose I have a command: foo -f text.txt. Can I emulate that text.txt? in order to avoid having that file in the wd?
Apr 28 14:31:34 <zmatt> you mean you want to invoke a program that wants a file argument, but instead of a file you want to pass it... what? the output of some other command?
Apr 28 14:52:49 <CoffeeBreakfast> zmatt yes
Apr 28 14:54:29 <CoffeeBreakfast> maybe sounds bad... because foo, i guess, would create a file descriptor of text.txt and yada yada
Apr 28 17:05:06 <zmatt> bash has <( COMMAND )
Apr 28 17:05:13 <zmatt> cat <(echo foo) <(echo bar)
Apr 28 17:06:43 <tbr> also xargs can be helpful
Apr 28 17:07:29 <mawk> CoffeeBreakfast: most commands support - instead of a file name
Apr 28 17:07:34 <mawk> to read data from stdin
Apr 28 17:08:06 <zmatt> that oo
Apr 28 17:08:08 <mawk> else if it doesn't work you can force it by using /dev/stdin as the file name and supply to stdin, else you can use what zmatt said by using <(make some text) as the file name
Apr 28 17:08:09 <zmatt> *that too
Apr 28 18:23:36 <gbguac> I need some guidance. I'm set to learn and develope an embedded pro audio device running on a Beaglebone Black. UI will be three low res displays (128x64px) and a bunch of push switches and rotary encoder. What would be an appropriate linux version to run this on? It needs to be compatible with ALSA and have drivers ready to go (No writing drivers myself)
Apr 28 18:29:54 <veremitz> zmatt: ^ :)
Apr 28 18:32:30 <zmatt> gbguac: as a general rule, if you feel the need to ask such a question, you probably just want to use the default distro (debian stretch), regardless of application
Apr 28 18:36:53 <gbguac> zmatt: Just trying to get a hint on where to start the journey... You are recommending debian. Can I boot directly into my application with that?
Apr 28 18:37:00 <gbguac> (thats my only question)
Apr 28 18:37:23 <zmatt> I mean, why not? why do you think that that's in any way distro-dependent?
Apr 28 18:38:04 <zmatt> that's just a simple matter of making your application a startup service
Apr 28 18:40:52 <gbguac> Cool beans.
Apr 29 00:01:40 <Throwaway> im drunk :$
Apr 29 00:20:00 <CoffeeBreakfast> Throwaway why?
Apr 29 00:20:56 <CoffeeBreakfast> I have OCD, so, i'm drunk with clonazepam
Apr 29 00:21:06 <zmatt> more importantly, why share that here of all places? :P
Apr 29 00:25:23 <CoffeeBreakfast> denial is a bad thing (speaking of me)
Apr 29 00:41:02 <Thisara> Can you please help me to update BBB
Apr 29 00:42:08 <set_> apt update?
Apr 29 00:42:44 <set_> Thisara: sudo apt update?
Apr 29 00:43:00 <mawk> update then upgrade
Apr 29 00:43:07 <mawk> update only updates the package database
Apr 29 00:43:08 <set_> Right-o!
Apr 29 00:43:13 <mawk> not the packages themselves
Apr 29 00:43:18 <set_> Got it.
Apr 29 00:43:20 <zmatt> depends on the context of "update"
Apr 29 00:43:27 <set_> Ut oh?
Apr 29 00:43:31 <zmatt> if it's for a big update, reflashing is usually the way to go
Apr 29 00:43:45 <zmatt> at least for people who need to ask how to update :P
Apr 29 00:44:24 <set_> Oh. I guess if you configure things to malfunction, a clean, new image is available for your taking.
Apr 29 00:44:55 <set_> bbb.io/latest-images is a site for the BBB to get a new image.
Apr 29 00:46:13 <set_> Hey zmatt: did you see my post about getting the gps3 w/ GPSD to write to a file in python?
Apr 29 00:46:27 <set_> Finally. I thought I was going to eat my keyboard for a second.
Apr 29 00:46:59 <set_> Here I come ---> Google Earth Pro!
Apr 29 00:49:35 <set_> Now. time to append!
Apr 29 00:51:50 <mawk> I'm learning usb, doing a usb to ttl converter to learn
Apr 29 00:51:56 <mawk> it's pretty complicated stuff
Apr 29 00:51:59 <mawk> descriptors all the way down
Apr 29 00:52:02 <Thisara> hello
Apr 29 00:52:08 <Thisara> hold on
Apr 29 00:52:09 <set_> Thisara!
Apr 29 00:52:11 <set_> Okay.
Apr 29 00:52:16 <mawk> device descriptor, configuration descriptor, interface descriptor, endpoint descriptors
Apr 29 00:53:09 <set_> So, you are learning how to transfer info. w/ and w/out powered electronics?
Apr 29 00:57:20 <Thisara> I need to reinstall original os
Apr 29 00:58:05 <set_> Thisara: Okay!
Apr 29 00:58:20 <set_> When you say original, did you erase something you are trying to get back?
Apr 29 00:58:24 <set_> Did you back up?
Apr 29 00:59:40 <Thisara> I tried to update the os. But it was unsuccessful
Apr 29 00:59:55 <Thisara> Now I need go back to original OS
Apr 29 00:59:57 <set_> Oh. did you use etcher w/ Win 10?
Apr 29 01:00:09 <set_> Or are you using Linux development desktop?
Apr 29 01:00:12 <Thisara> Etcher W
Apr 29 01:00:18 <set_> Okay.
Apr 29 01:00:24 <Thisara> I'm using window
Apr 29 01:00:26 <Thisara> 7
Apr 29 01:00:30 <set_> Okay. Ut oh.
Apr 29 01:01:07 <set_> I thought you might be on an updated system. Please hold.
Apr 29 01:01:25 <Thisara> ok
Apr 29 01:01:57 <set_> https://beagleboard.org/getting-started
Apr 29 01:02:05 <set_> This has some info. for you to review.
Apr 29 01:02:47 <set_> Hey Thisara: Did you wait long enough to sign in?
Apr 29 01:02:59 <set_> 192.168.7.2?
Apr 29 01:03:00 <Thisara> OK.! I followed all the instruction
Apr 29 01:03:12 <set_> Oh. Okay.
Apr 29 01:03:27 <set_> So, I am being nosey b/c I am trying to figure out what you may have done.
Apr 29 01:03:32 <Thisara> I write the image on the SD card
Apr 29 01:03:39 <set_> Okay.
Apr 29 01:03:41 <set_> And...
Apr 29 01:03:58 <set_> Flasher or Stanalone?
Apr 29 01:03:59 <Thisara> I boot up with pressing boot button
Apr 29 01:04:04 <set_> Okay.
Apr 29 01:04:16 <set_> Sorry. Standalone or Flasher?
Apr 29 01:04:32 <Thisara> but it did not came on the all light standalone
Apr 29 01:04:49 <Thisara> Flasher
Apr 29 01:04:52 <set_> Standalone?
Apr 29 01:04:55 <set_> Oh. Flasher?
Apr 29 01:05:00 <set_> Okay.
Apr 29 01:05:19 <set_> Did you take out the sd card before powering the board back on for it to boot up?
Apr 29 01:05:27 <Thisara> yes
Apr 29 01:05:48 <set_> So, you have no sd card in your BBB and you installed the Flasher image and no go?
Apr 29 01:06:00 <Thisara> but it's not showing on the my computer as flash drive
Apr 29 01:06:06 <set_> Oh.
Apr 29 01:06:08 <set_> Got it.
Apr 29 01:06:32 <Thisara> I was trying connect using Putty
Apr 29 01:06:38 <Thisara> but time out
Apr 29 01:06:45 <set_> There is a section to install drivers. I am not sure but i think in Win 7 there were drivers. But! Try to use PuTTY and sign in anyway.
Apr 29 01:06:46 <set_> Oh.
Apr 29 01:07:12 <set_> Thisara: Where did you get this flasher image?
Apr 29 01:07:30 <set_> Site or repo?
Apr 29 01:08:41 <Thisara> I downloaded form BB website
Apr 29 01:08:59 <set_> The newer image on IoT or Lxqt?
Apr 29 01:09:01 <set_> Or another one?
Apr 29 01:10:01 <Thisara> I tried Debian 8.5 2016-05-13 4GB SD LXQT
Apr 29 01:10:23 <Thisara> But did not works
Apr 29 01:10:42 <Thisara> I followed https://medium.com/@zageollc/updating-the-software-image-on-a-beaglebone-black-fc73ffcc700
Apr 29 01:10:43 <set_> Okay. I know this may be annoying but try the newer image in BLUE. Serious. It will work just fine. They have iot and lxqt for a GUI.
Apr 29 01:11:40 <Thisara> I tried Debian 9.5 2018-10-07 4GB SD IoT
Apr 29 01:11:50 <Thisara> but still same
Apr 29 01:11:51 <set_> Okay.
Apr 29 01:11:54 <set_> Oh.
Apr 29 01:12:06 <set_> You need to update your bootloader or just erase the eMMC.
Apr 29 01:12:16 <set_> Do you have important info. on your BBB?
Apr 29 01:12:27 <Thisara> how can I erase the EMMC
Apr 29 01:12:59 <set_> Please hold.
Apr 29 01:13:14 <Thisara> But my BBB not detecting now
Apr 29 01:13:14 <set_> I will have to look that up on the google groups.
Apr 29 01:13:25 <set_> It may take a while.
Apr 29 01:13:36 <Thisara> ok
Apr 29 01:14:15 <set_> Thisara: While you are waiting, you can review that info. too. For instance, on google or the google groups, search: erase eMMC on BBB.
Apr 29 01:14:19 <set_> I will do the same.
Apr 29 01:14:27 <set_> First one back wins!
Apr 29 01:14:30 <set_> Go!
Apr 29 01:15:36 <Thisara> I'm looking at it
Apr 29 01:16:12 <set_> Oh.
Apr 29 01:16:24 <set_> Me too. I just forgot. You cannot sign in for some reason.
Apr 29 01:16:33 <set_> This will not work either.
Apr 29 01:16:39 <set_> Dang!
Apr 29 01:17:18 <set_> Hmm. I wonder.
Apr 29 01:17:28 <set_> What is your usb cable like as of now/
Apr 29 01:17:30 <Thisara> mmm
Apr 29 01:17:51 <set_> I mean...is it plugged in via a usb connector on your computer that accepts power too?
Apr 29 01:18:12 <Thisara> its plugged
Apr 29 01:18:18 <set_> Some usb connections on computers do not accept power. They will not power your device.
Apr 29 01:18:43 <set_> I actually had a problem w/ my BBB not working on my computer uSB port b/c of this issue.
Apr 29 01:19:20 <Thisara> OK. I tried both the method
Apr 29 01:19:41 <set_> Thisara: I am trying here. I do not know everything but from what I can tell, there might be a step you are missing.
Apr 29 01:19:44 <Thisara> Separate power supply
Apr 29 01:19:52 <set_> Did you use 7-zip?
Apr 29 01:19:59 <Thisara> yes
Apr 29 01:20:05 <set_> Okay.
Apr 29 01:20:24 <set_> So, you are using a 5v adapter and the USB?
Apr 29 01:22:35 <Thisara> I used separate power supply for BBB
Apr 29 01:22:57 <Thisara> but now its only on USB with out powered
Apr 29 01:23:21 <Thisara> Now its detecting with micro SD
Apr 29 01:23:27 <set_> yea!
Apr 29 01:23:29 <Thisara> In Putty
Apr 29 01:23:32 <set_> Yea!
Apr 29 01:23:51 <set_> Sometimes it takes a one to conquer a million.
Apr 29 01:23:51 <Thisara> But it has to be with microSD
Apr 29 01:23:58 <set_> Wait.
Apr 29 01:24:16 <set_> You want to have the SD Card version of the image on your BBB?
Apr 29 01:24:24 <set_> Right/
Apr 29 01:24:39 <Thisara> yes
Apr 29 01:24:59 <set_> I say update your image from the site: bbb.io/latest-images and pick on of the two BLUE options.
Apr 29 01:25:14 <set_> They are both SD Card versions.
Apr 29 01:26:14 <set_> Now, if you want to test and make trials, you can always go to https://elinux.org/Beagleboard:BeagleBoneBlack_Debian.
Apr 29 01:26:26 <Thisara> the problem is I'm going to use this BBB with MATHLAB
Apr 29 01:26:32 <set_> Most of those work constantly.
Apr 29 01:26:38 <set_> MATLAB?
Apr 29 01:26:48 <set_> Or is it actually MATHLAB?
Apr 29 01:26:49 <Thisara> yes
Apr 29 01:27:11 <Thisara> sorry
Apr 29 01:27:14 <Thisara> Matalb
Apr 29 01:27:20 <set_> There was some older stuff I remember from Lynx and Matlab.
Apr 29 01:27:25 <Thisara> Matlab
Apr 29 01:27:28 <set_> W/ the BBB!
Apr 29 01:27:37 <set_> Hold on.
Apr 29 01:27:39 <set_> I am going to find it.
Apr 29 01:27:45 <Thisara> ok
Apr 29 01:29:33 <set_> Sorry. That was Labview instead. I was wrong.
Apr 29 01:30:30 <Thisara> https://www.mathworks.com/matlabcentral/answers/264680-error-on-coI saw this mpilation-of-example-getting-started-with-embedded-coder-support-package-for-beaglebone
Apr 29 01:30:45 <Thisara> I saw this .-https://www.mathworks.com/matlabcentral/answers/264680-error-on-compilation-of-example-getting-started-with-embedded-coder-support-package-for-beaglebone
Apr 29 01:33:08 <Thisara> hello
Apr 29 01:33:23 <set_> Hello.
Apr 29 01:33:44 <set_> Sorry. I am getting beat here. The append portion to my software is not working right now.
Apr 29 01:34:04 <set_> The first portion of the software gets appended and then boinkers happens.
Apr 29 01:34:05 <set_> ...
Apr 29 01:34:12 <set_> Do you want me to look at that link?
Apr 29 01:34:32 <Thisara> Yes the second link.
Apr 29 01:34:40 <set_> Okay.
Apr 29 01:35:12 <set_> Hey. Why do you want me to look at that site?
Apr 29 01:35:31 <Thisara> I had a issue with Matab communication
Apr 29 01:36:02 <set_> Okay.
Apr 29 01:36:09 <Thisara> It is the problem
Apr 29 01:36:11 <set_> What was the issue?
Apr 29 01:36:32 <set_> You want to communicate and it says "NO COMMUNICATION!" here?
Apr 29 01:36:59 <Thisara> There was set of errors
Apr 29 01:37:07 <set_> pastebin.com!
Apr 29 01:37:30 <Thisara> I talked to matlab
Apr 29 01:37:36 <set_> How are you communicating, i.e. adc, uart, i2c, blah?
Apr 29 01:38:25 <Thisara> I was triying to communicate through matlab
Apr 29 01:39:38 <Thisara> Mat lab recommended  me to do some works
Apr 29 01:40:07 <set_> Oh.
Apr 29 01:40:18 <set_> So, they want to have you search around the net?
Apr 29 01:41:10 <set_> Thisara: Do you know how to append c = new_data after I write to a file w/ d = open('blah.txt', 'w')?
Apr 29 01:41:14 <set_> In Python3?
Apr 29 01:42:39 <Thisara> they commandeered me to do following
Apr 29 01:42:52 <Thisara> Hello
Apr 29 01:43:12 <Thisara> sorry
Apr 29 01:43:20 <set_> Okay.
Apr 29 01:43:26 <set_> It is okay.
Apr 29 01:43:29 <set_> I do not mind.
Apr 29 01:43:37 <set_> I just wondered something...
Apr 29 01:43:45 <Thisara> What do you need to do
Apr 29 01:43:56 <set_> pastebin.com would be a good source for error codes?
Apr 29 01:43:57 <Thisara> What Do I need to do
Apr 29 01:44:21 <Thisara> ok
Apr 29 01:44:42 <set_> Thisara: Hey! I am on break for 10 minutes. I will brb.
Apr 29 01:45:02 <Thisara> ok.
Apr 29 01:45:08 <Thisara> sorry
Apr 29 01:48:54 <set_> Okay.
Apr 29 01:49:05 <set_> Man. I am beat. This dang append is killin' me.
Apr 29 01:49:18 <set_> pastebin?
Apr 29 01:50:18 <set_> Oh hey.
Apr 29 01:51:14 <set_> I saw your link. Look here: https://www.digikey.com/eewiki/display/linuxonarm/BeagleBone+Black.
Apr 29 01:52:02 <set_> I saw what the person said. It looks like your toolchain is non-configurable w/ the version of Debian.
Apr 29 02:01:17 <Thisara> Hello
Apr 29 02:01:37 <Thisara> I think I got some installation date pattern
Apr 29 02:01:43 <Thisara> let see

Apr 29 02:35:50 <set_> Hello!
Apr 29 02:36:06 <set_> Thisara...can you get into the BBB?
Apr 29 02:36:18 <set_> sign in?
Apr 29 02:41:37 <Thisara> yes
Apr 29 02:42:08 <Thisara> I think it problem with pc. Ill reinstall BBB brivers
Apr 29 02:42:19 <Thisara> Drivers
Apr 29 02:53:58 <set_> Okay.
