**** BEGIN LOGGING AT Fri Apr 20 03:00:01 2018 Apr 20 07:28:12 hi how to i make it free HDMI pins as a GPIO pins Apr 20 07:29:16 some pins are reserved for HDMI how should i disabled that pins and used for gpio purpose Apr 20 07:31:24 Nagarjuna: you need to disable the overlay that reserves them. When flashing latest images, this is now done in U-Boot. Information is available if you search the web for this. Apr 20 07:33:14 sir i was not flashing OS in eMMc . i was enabled all gpio pins purpose i have used SD card direct inserted into beagleboneblack. is there all HDMI pins are now not free Apr 20 07:33:46 i tested /sys/class/gpio Apr 20 07:34:01 yes, obviously you need to boot from microSD. Still it applies to latest images that you need to make changes in U-Boot Apr 20 07:34:12 43 pins are enabling there it it showing Apr 20 08:07:37 hello Apr 20 08:08:02 do the new images for the bbb have the "jitter patch" mentioned here: https://groups.google.com/d/msg/beagleboard/lsCJzpLCXsw/_Wrg7y3LAwAJ ? Apr 20 08:08:21 (patch fot the touchscreen capes) Apr 20 09:56:21 Hi, Apr 20 10:34:36 Hi, we are in need of BBONE-BLACK-4G. whom to contact? Apr 20 11:18:23 Hi ..im manu Last month i buying beagle bone black rev c But in this board having 65 pin gpii, but in this goio only 30 pins are input pins.. So my question is "How to expand gpio input pins"?? Or how to make gpio output pin into input pin?? bcoz i need 60 pin as input pin so Plz reply me Apr 20 11:19:09 have a look at the system reference manual Apr 20 11:19:19 that will give you an idea which pins are available Apr 20 11:19:37 if you boot from microSD card and disable HDMI, you can free some additional pins for GPIO Apr 20 11:20:43 my queston is simple how to make gpio output pin into input pin?? bcoz i need 60 pin as input pin so Plz reply me Apr 20 11:21:04 i need ans for this Apr 20 11:21:10 plz reply me Apr 20 11:21:32 in python...not in terminal Apr 20 11:21:53 manu_: it does not work like that. Apr 20 11:22:16 manu_: look at the advice tbr gave you, you will need to modify the system configuration. Apr 20 11:23:42 how yto modified system configuration../.// Apr 20 11:25:37 manu_: here is some idea to get you started: https://elinux.org/EBC_Disabling_HDMI Apr 20 11:26:13 manu_: as well as here: https://elinux.org/Beagleboard:BeagleBone_Black_FAQ#What_is_the_process_for_disabling_the_HDMI_and_eMMC_Virtual_Capes.3F Apr 20 11:27:52 not sure if that still applies though Apr 20 11:28:09 overlays moved to U-Boot and capemgr is off by default AFAIU Apr 20 11:50:10 do the new images for the bbb have the "jitter patch" mentioned here: https://groups.google.com/d/msg/beagleboard/lsCJzpLCXsw/_Wrg7y3LAwAJ ? Apr 20 12:04:44 parduz: doesn't look like it. maybe contact rcn and ask him why the patch was dropped Apr 20 12:06:49 zmatt: only read your answer about contacting him Apr 20 12:07:02 then had to reload Apr 20 12:07:15 that was all I said Apr 20 12:07:24 ok Apr 20 12:07:30 how to reach him? Apr 20 12:07:44 he did'nt ansered to my question there Apr 20 12:09:59 that's probably because the core question was mixed with a couple of noob questions ;) he doesn't have the time to pay attention to everything on that mailing list Apr 20 12:14:04 ok :) Apr 20 12:14:19 so what's the best way to reach him? Apr 20 12:14:22 I'll reply to your post and cc him Apr 20 12:14:55 oh. thanx Apr 20 12:22:12 parduz_: actually, can you pm me your email address? I'll just send him a direct message and cc you Apr 20 12:23:23 since I'm not sure how he organizes his inbox... it's possible replying to an old thread might just cause the message to get buried somewhere Apr 20 12:24:19 dunno how to PM you from here. Apr 20 12:24:28 /msg zmatt ... Apr 20 12:30:31 got it? Apr 20 12:30:41 yes Apr 20 12:30:51 :) Apr 20 12:31:08 mail sent Apr 20 12:33:58 thanks a lot Apr 20 12:37:27 it's also not very hard to apply the patch yourself if you have a somewhat decent debian/ubuntu system to recompile the kernel (a VM running on windows may suffice) Apr 20 12:44:32 zmatt: i'll need a step-by-step guide (up to date). I already struggle so much with what i'm done without the doubt that i may be the cause of my own problem :) Apr 20 12:45:15 i have a functioning Debian VM, anyway Apr 20 12:46:35 but in the end, i tend to trust more the ones that dropped the patch.... i suppose it happened for a reason.... i hope :) Apr 20 12:46:50 can just as easily have been an oversight/accident Apr 20 12:47:42 I guess it's probably easier to just wait for rcn's reply Apr 20 12:53:18 yep :) Apr 20 13:08:03 I want to access "GPIO_86" in beagle bone black. Whenever I give " ls " command in " root@beaglebone:/sys/class/gpio# " , "GPIO_86" is not visible. Is that pin configured for HDMI? Apr 20 13:20:16 that's... gpio 2.22 ... P8.27 / lcd vsync . yep, if you have a beaglebone with hdmi output it will be configured for hdmi by default unless you disable that in /boot/uEnv.txt Apr 20 13:21:06 assuming you're using a recent image, uncomment (i.e. remove the # in front of) disable_uboot_overlay_video=1 Apr 20 14:34:50 is the "supercar pattern" while flashing still a thing? Apr 20 14:46:43 yes Apr 20 14:47:39 then i did'nt flash anything on my new BBB WiFi :| Apr 20 14:48:03 it do not boot without the mSD, now Apr 20 14:49:33 how did you try to flash it? Apr 20 14:49:46 the uEnv nano mod Apr 20 14:50:16 if it boots normally from the sd card then that would suggest you didn't do the mod right, since if you did it would always boot straight into the flasher Apr 20 14:50:50 hi how can i boot the os in SD card not boot in eMMC Apr 20 14:50:52 ....i nanoed the uEnv on the eMMC, not on the mSD. Apr 20 14:50:54 geez Apr 20 14:51:15 parduz_: lol Apr 20 14:51:28 reddy: if a bootable sd card is inserted it will normally boot from it automatically Apr 20 14:52:08 but here the problem is when i was inserted SD card in beagleboneblack it is flashing Apr 20 14:52:23 than automatically it is used the eMMC Apr 20 14:52:33 then the sd card is a flasher and not a standalone bootable sd card Apr 20 14:52:42 you can change that by editing the /boot/uEnv.txt file on the sd card Apr 20 14:54:30 when i was connected SD card from the PC it is asking format it con't open Apr 20 14:54:46 windows doesn't support linux filesystems Apr 20 14:55:06 if your beaglebone boots from emmc, you can use that to edit the contents of the sd card Apr 20 14:55:27 or download a standalone image from the website and flash that onto the sd card Apr 20 14:55:43 i was used 9.1 Apr 20 14:55:44 all images at https://bbb.io/latest-images are standalone Apr 20 14:56:26 (in contast, https://elinux.org/Beagleboard:BeagleBoneBlack_Debian has both standalone images and flashers... you just need to pay attention to which one you download) Apr 20 14:57:04 9.1 is pretty old btw Apr 20 14:57:12 current images are 9.3 Apr 20 14:57:30 (or 9.4 for the testing images) Apr 20 14:57:41 oho kk 9.2 is also very old Apr 20 14:57:53 or can i use that one Apr 20 14:58:40 uhh, you can use whatever version you want of course, but unless you have a specific reason to use an old image I would recommend using the latest Apr 20 14:59:08 the first download link at https://beagleboard.org/latest-images is recommended for most users Apr 20 15:03:35 ...short linux question (so, no strictly BBB related): Apr 20 15:04:13 how could i avoid to type "xhost +" each time i want to compile and see output via SSH? Apr 20 15:04:23 so, having it permanently enabled? Apr 20 15:04:40 uhh, what?! Apr 20 15:04:46 xhost + is normally never needed Apr 20 15:04:53 what are you doing exactly? Apr 20 15:05:05 also, what does this have to do with compiling stuff and using ssh ? Apr 20 15:05:12 xhost is purely related to x11 Apr 20 15:05:43 i launch UI app from SSH, it don't start if i dont do that on the BBB and export DISPLAY=:0 via SSH Apr 20 15:06:40 ahh Apr 20 15:07:12 so, i compile my app from my WinPC, launch it, and have the app on the LCDcape and the debug output on my PC Apr 20 15:07:27 setting DISPLAY should suffice? unless you've logged in as a different user as the one that's logged into x11 Apr 20 15:08:04 i log as root, while the user on the desktop is Debian Apr 20 15:08:17 generally you shouldn't log in as root Apr 20 15:09:34 it saves time when i need to recompile/apt-get libraries Apr 20 15:09:59 just use sudo Apr 20 15:10:05 sudo apt-get whatever Apr 20 15:10:32 doing random stuff like compiling software as root is a bad habit Apr 20 15:10:47 also, it's what's causing your x11 permission issues Apr 20 15:10:47 oh Apr 20 15:11:30 i'll look about why it is bad habit . Apr 20 15:11:44 now, it's friday at 5pm. Apr 20 15:11:50 it's a bad habit because root bypasses all filesystem privileges Apr 20 15:12:00 so a small accident can easily wreak havoc Apr 20 15:12:09 i see. Apr 20 15:12:39 ok, i'll set my connections next week Apr 20 15:12:46 now is time to shut everything off Apr 20 15:12:55 have a nice w.e., zmatt :) Apr 20 15:12:57 thnx a lot Apr 20 15:16:09 Hi, what is the easier or "lightest" way to display an IP camera streaming in a beaglebone lcd7 ? Apr 20 16:16:40 vlc? Apr 20 16:21:32 I doubt vlc qualifies as "light" Apr 20 16:22:15 sure it can....if emacs is "normal weight", vlc is light ;) Apr 20 16:51:17 "Easier" was also a criterion. Apr 20 18:11:05 the only software that seems to insist on being compiled as root appears to be pip install python crap Apr 20 18:11:29 there may be a fakeroot way around it, but i've never found one Apr 20 18:48:07 might pypi-install from https://pypi.org/project/stdeb/ be a solution? Apr 20 18:48:16 also to make it easier to remove stuff Apr 20 18:50:03 (actually I don't know if the latter comment applies... for some reason I just assumed there's no tracking of installed files when you use pip but I actually have no idea, I don't use python that much) Apr 20 20:47:06 hi there channel :-) Apr 20 20:49:41 ;;seen fortnight Apr 20 20:54:20 !seen #beagle fortnight Apr 20 20:54:49 !seen #channel fortnight Apr 20 20:54:56 stop that please Apr 20 20:55:00 there's no bot here with !-commands Apr 20 20:55:52 how do I see when was last seen for fortnight Apr 20 20:55:56 but you can probably ask nickserv with: /msg nickserv info set_ (he was temporarily using the nick "fortnight" earlier because set_ was taken) Apr 20 20:56:34 ok Apr 20 20:57:05 sorry about that, zmatt Apr 20 20:58:46 zmatt, robotics cape with rev c. matches great? Apr 20 20:59:45 syntax error: unable to parse sentence Apr 20 21:01:43 zmatt, robotics cape with rev c. I mean.. Is it good for drone and other projects Apr 20 21:02:04 I have no experience with the robotics cape Apr 20 21:02:35 all right Apr 20 21:38:27 good night all :-) Apr 20 22:10:57 hello Apr 20 22:11:08 Hello, this is my 1st access and question. I just bought this BBG a few days ago. I can connect via USB at 192.168.7.2 and via putty on ethernet at 192.168.0.109 (my local IP for this BBG). I also did update and upgrade after fresh flashings. I tried most of the "getting started" things okay. I have Debian 9.3 (I tried both iot and graphical desktop versions). I have searched the web and found numerous references and "how-to's" for get Apr 20 22:11:46 alice: too much text in one line, it got cut off after: references and "how-to's" for get Apr 20 22:11:56 without requiring a login. I tried a number of them; "bricked" my BBG and had to restart from the SD card and flash that to the eMMC. Many of those were very old posts. I tried looking only for the later Debian methods but, IF they would have worked, I am new to Linux and I don't know enough (yet) to do those things. Apr 20 22:12:18 I am using the BBG on a locall network and so I have no security issues with this BBG not having a login/password (it is not accessible via internet; it is private). I have applications (for home automation) and so I do not need a display monitor or keyboard/mouse; it will be headless with only an ethernet and 5v power connections (aside from a cape to local sensors). Apr 20 22:12:37 I have a python program that I had previously used on a Windoze PC and an Arduino application that I am/will port to the BBG as soon as I figure it out. Apr 20 22:12:52 Here is what I need: 1) when power is applied it should boot without any human interaction --- I assume this means no login/password 2) after booting it should run both my python app and my ported Arduino app (I haven't decided to keep the sketch with .ino and use Cloud9 or convert it to C and gcc it or start over with Node-Red)(whichever is better?). These must be simple things but I'm new to both BB and Linux so I hope you can help Apr 20 22:13:09 direction --- thanks! Apr 20 22:13:40 jeez what a wall of text... but I'm getting the impression you're just asking "how do I make a service that runs at startup?" Apr 20 22:14:25 and alice might want a connection from the BBG to the Arduino, too? Apr 20 22:15:02 no connectoin to Arduino, I already have that working to my PC Apr 20 22:15:08 Oh. Apr 20 22:15:11 Okay. Apr 20 22:15:15 I want to avoid the login. Apr 20 22:15:42 Oh. No login at boot? Apr 20 22:15:58 alice: i.e. you just want your program to run at startup Apr 20 22:16:00 and, whats the diff between "service" and an "application program" ? Apr 20 22:16:00 i.e. make a service Apr 20 22:16:17 a service is a program that runs on the system to perform some task in the background Apr 20 22:16:30 (either automatically at startup, or in response to some sort of request) Apr 20 22:16:39 as opposed to something you run as a user after logging in Apr 20 22:16:59 ah, ok, so I don't care if background or foreground cause theres no display or keyboard Apr 20 22:18:11 So...get a service to run when the BBG starts up w/out any input or... Apr 20 22:18:12 Or... Apr 20 22:18:16 it will monitor water pump and batteries and takes commands via UDP from my PC and reports back via UDP those parms Apr 20 22:18:34 you were right zmatt. Apr 20 22:18:39 alice needs a service. Apr 20 22:18:53 yup, I just want power-up and run app (or service) Apr 20 22:18:55 https://pastebin.com/Wkx6r9b3 Apr 20 22:19:33 this runs your program as root. if you don't need that you can e.g. put: User=debian in the [Service] section Apr 20 22:20:04 there are lots more config variables available to tweak the environment in which your service runs, this is just the basics Apr 20 22:21:06 alice, are you using the Greg-R stuff on GitHub.com? Apr 20 22:21:07 I don't want to bother you too much, so where can I find more about config variables to tweak? Apr 20 22:21:30 WorkingDirectory=/some/dir may also be useful to set the current dir (like "cd" would in the shell) Apr 20 22:21:32 no (Greg-R stuff) Apr 20 22:21:36 Okay. Apr 20 22:21:40 https://www.freedesktop.org/software/systemd/man/systemd.service.html Apr 20 22:22:05 and a few other man pages that are linked to in the Description section of this man page Apr 20 22:22:38 gotem (open other tabs - I'll bookmark) - - - thanks much ! Apr 20 22:23:15 now I'll go try stuff again. Nice knowing I can always revert to SD card if I goof up. Apr 20 22:23:33 the systemd.unit manpage describes how to add dependencies, e.g. if you make two services and start one before the other Apr 20 22:24:10 I'm not afraid to jump in deep water, I just don't want to drown. Apr 20 22:24:34 But I need to take baby steps right now - thanks for your helps **** ENDING LOGGING AT Sat Apr 21 03:00:05 2018
